1、Scheduling winch models commonly used mainly JD-0.4 (JD-4.5)、 JD-1 (JD) -11.4)、 JD-1. (JD-22)、 JD-2 (JD-25)、 JD-3 (JD - 40). Below the JD-3 (that is、 JD-40) as an example of scheduling winch on the composition and scheduling transmission principle. (A) JD-3-scheduling of the winch JD-3-scheduling th
2、e main component of the winch drum for、 brakes and motor frame. From the winch drum made of cast steel、 its main function is winding rope traction load. Drum、 and the slowdown in gear with the gear. Winch on the two groups with a total installed-gate that is Brake 2、the gateway 3. Motor side of the
3、gate 2 to brake drum brakes、 the gear in the work of three gates used to control Z7 group functioning. Use made of cast iron frame、 the motor bearings and gates with stent-positioning are fixed with bolts in the plane seat. For Flameproof for the thee-phase motor .(B) JD-3-Dispatch winch the drive p
4、rinciple this type of winch used two Internal Drives and a planetary gear transmission. Z1/Z2 and Z3/Z4 for two Internal Drive、 Z5、 Z6、 Z7 composition of planetary transmission mechanism. Motor head in the installation of a 5-axis extended sets of gear Z1、 through the gears Z2、 with gear Z3 and Z4、
5、the movement spread to gear Z5、 the Z5 is the planetary gear wheel of a central round (or round of the Sun) And then led the two planetary gear Z6、 and the gear Z7. Planetary gear freely installed in the two driven and connected to a fixed axis、 the largest in the gear Z7 Gear work with the external
6、 gateway、 used to control winch drum operation. If the big gear Z7 gate on the work of three gates to live、 and will be on the brake drum gates 2 release、 this time by two motor rotation within the rodents to gear wheel drive Z5、 Z6 and Z7. However、 due to Z7 gate has been living and can not rotate、
7、 so gear Z6 only on the one hand around its own axis of rotation、 but also around the axis of gear Z5 (drum center) to the public. Thus connected with the rotation of the lead、 then Z6 the operation mode very similar to the planets in the solar system (such as Earth) movement、 also known as the plan
8、etary gear Z6、 its transmission mode known as the planetary transmission. Conversely、 if the gear Z7 in the work release gate 3、 and will brake drum on the live gate 2、 the Z6 directly connected with the drum、 only for the rotation、 not revolution、 the Z1 from the transmission system changed to Z7 F
9、or the fixed axis of the round、 gear Z7 to go short. Inverted for the release (or live gate) gate work Brake 2 or 3、 you can make scheduling winch in the case of non-stop motor to achieve operating and parking. When the need to reverse upgrade、 must be re-activated the launch button、 reverse the mot
10、or running. It should be noted that、 when the motor is turned on、 the gate and not allowed to work Brake live gate at the same time、 it will burn motor or other accidents. Second、 scheduling winch day-to-day maintenance check the contents of (1) check each part of bolts、 pin、 nuts、 washers、 etc.、 if
11、 loose、 loss should be tightened and timely complement. (2) to check installations and electrical signal Operation button is intact and whether stolen explosive phenomenon、 whether the signal sent clear and bright、 it should be repaired or replaced. (3) to check whether damaged or broken drum、 the f
12、irst wire rope is firmly fixed、 bearing oil spill there、 the rope is neatly arranged、 the problems should be promptly dealt with. (4) inspection gate with a crack-free、 wear-gauge whether or not (should have a thickness of not less than 3 mm)、 the tension bar bolts、 fork first、 the gate、 such as whe
13、ther there is a pin deformation or injury、 whether the loose nuts back tight、 Problems should be adjusted and dealt with. (5) Check the gate and lever action is a flexible system、 Shi gate、 the ate may not reach the level position、 it should be slightly Sangria than the horizontal position. (6) to c
14、heck the roof fixed winch-and-beam is solid、 based on whether there is a bolt or bolts loose、 whether crack base、 the issue should be dealt with promptly. (7) To check whether the normal start motor idling、 whether good grounding to start with、 and so whether the explosion-proof electrical equipment
15、 and good demand. (8) Check bearings and motors、 switches、 cables、 such as whether the gate with the temperature too high、 the problem should be found to identify the reasons for、 to take measures to deal with. (9) Often wipe winch to remove dust and debris、 and maintain the environment clean and ti
16、dy. Winch the safe operation、 inspection and maintenance Third、 winch common faults and deal with (A) a winch drum abnormal sound and the main approach 1. Winch drum produce abnormal sound the main reason (1) drum cartridge case bolts loose. (2) Shell and tube-round (flange) gap between too large. (
17、3) Drum cylinder shell cracks. (4) Welding a cylinder shell welding. (5) Walks drum and hub of the fixed screw loose、 causing swimming drum and hub between the relative sliding. (6) Gap between the hub and spindle wear too large. (7) A clutch worm screw loose. 2. Approach According to the inspection
18、 to determine treatment. If the loosening of the nut、 in Jiao Ban shutdown when fastening If noise is not serious、 may be appropriate to reduce winch load、 pay attention to observe、 to maintain the provisions of the maintenance shutdown at the repair if the beep serious、 they should immediately Park
19、ing repaired or replaced、 so as to avoid accidents expand. (B) On the rope winch drum with Bu Shangri hazards、 causes and treatment methods、 1. Winch drum on the rope with the harm Bu Shangri (1) speed up the rope wear. Rope in the mess on the winding drum、 traction force to justice often ranked in
20、the mess in the rope and pressure to get out、 causing serious wear、 resulting in diameter steel wire rope and wire break more ground and shorten the life of the rope. (2) Of wire rope slid off the drum. Rope with Bu Shangri、 an inevitable phenomenon of a crowded heap for damage to justice board、 whe
21、n the reactor crowded the edge of more than high rollers、 the rope easily slid off the drum、 light、 broken wires、 heavy sports car、 and broken rope. 2. Winch drum on the main rope with Bu Shangri (1) winch layout properly that is hoisting cable angle non-compliance requirements. (2) Winch Titanium (
22、Preliminary round) Quemoy not with the rope on the winding drum at about sliding. (3) Ranked rope winch device failure or have been removed. (4) Improper operation the wound is not tight. 3. Approach According to different situations symptomatic treatment. The installation of quality and exclusive r
23、ope devices such as the failure to timely report on the request sent treatment、 operation or maintenance of an improper、 we should conscientiously in accordance with the provisions of meticulous operation and maintenance; Inclined Drift winch paying particular attention to removing obstacles on thei
24、r way to prevent the re-delegate Of Mandrel、 tight-rope Mandrel. (C) Winch reducer operation abnormal sound and vibration generated in the causes and treatment 1. Reducer functioning of abnormal sound and vibration generated in the main (1) gears meshing space tight or too loose. (2) Bearing gap is
25、too large、 the general performance of the decentralization empty at the beep、 beep when upgrading heavy small. (3) Or bearing reducer bolts loose. (4) Reducer in the swap was foreign bodies. 2. Approach (1) adjusting the gears meshing gap to a suitable position、 if the wear and gear should be replac
26、ed. (2) Relaxation of the repair or replacement of bearings. (3) Pay attention to tighten loose screws. (4) If it has fallen into foreign body reducer、 should be immediately suspended、 and troubleshooting. (D) Winch brake gate of the reasons for and treatment of fever 1. Brake winch for fever (1) a
27、gate too early、 too excessive. (2) Weights are often delegated to use Brake、 no electrical power winch braking system EC、 single-drum winch often such a situation. (3) Brake shoe loose bolts or excessive brake wear、 the bolt hit the first round of gate (or gateway disc). (4) Brake shoe and the gatew
28、ay round (or gateway disk) was not installed correctly; the contact area is too small. (5) Gate Ferry (or gateway disc) swing more. 2. Prevention and treatment Constantly sum up experience in operations、 and explore methods of operation and improve the level of technique; strict winch the safe operation、 inspection and maintenance of traction control grid load、 no-load、 do not send delegate at the motor-vehicle gate flying; regular maintenance checks、 pay attention to brake shoe and the gat
