[0002] At present, during the construction of power transmission projects in my country, most of the heavy objects and tools used for lifting are capstans. Capstans are essential construction tools for tower assembly process, and can provide necessary power for tower assembly construction smoothly and conveniently in various complex plateau and mountainous terrains. Existing capstans are generally driven by oil extraction machines, which are seriously polluting. The gearboxes are mostly manually operated for speed change, which is inefficient and not very maneuverable. The layout of the capstans is not compact enough, and the overall volume is relatively large, which is not convenient for transportation and is not suitable for construction environments with complex terrain.

[0003] Therefore, it is necessary to develop a reasonable pure electric servo motor driven winch to solve the above problems.

The utility model slides the support block mechanism backward, the front end of the drum wheel slides into the inner wall of the support block mechanism, and then presses the limit block downward, so that the limit block presses the connecting rod, thereby increasing the tightness of the support block mechanism, so that the drum wheel does not need to be pressed on the output end of the transmission member mechanism all the time, and the cleaning block at the lower end of the cleaning column cleans the wire rope wound on the drum wheel; but the device is driven by a generator, and the gear shifting is manual, so the structure is complicated, the maneuverability is not strong, and the volume is large, and it is not easy to transport.

In this way, the execution drum assembly 1 is in a suspended state, and the wire rope can be wound around the groove of the upper drum through its bottom.

[0032] When implementing:

[0033] Before the capstan driven by the pure electric servo motor works: first, pass the anchor wire through the two pull rings 34 to fix the anchor to the ground, thereby ensuring that the capstan can be stably maintained in place when working. Then, remove the four pins 515 installed in the support plate 511 and the fixing seat 514, then pull the lifting handle 513 to rotate the support plate 511 around the sliding sleeve 512 (when the support plate 511 rotates, the lower end has enough rotation space to avoid interference with 315). Please refer to Figure 4 The figure shows a schematic diagram of the capstan support plate being opened. At this time, one end of the traction wire rope can be placed in the tail rope rack, starting from the bottom of the second drum 42 close to the side of the gear reducer 2, the wire rope is placed in the groove of the drum, and is wound clockwise around the two drums. After winding seven times, the grooves of the two drums are filled, and the other end of the wire rope comes out from the bottom of the first drum 41 away from the side of the gear reducer 2. The wire rope at this end is placed in the rope outlet rack 32. At this point, the winding of the wire rope of the capstan is completed, and the wire rope at one end of the rope outlet rack 32 can be connected to pull the heavy object to perform the lifting work.

[0034] When the capstan driven by a pure electric servo motor is working: first, the first servo motor 11 and the second servo motor 12 are started synchronously to provide sufficient torque and speed to drive the rotation of the first input shaft 21 and the second input shaft 22, and the transmission is carried out through the gears in the gear reduction box. After multi-stage transmission, large torque and low speed are provided to the first output shaft 23 and the second output shaft 24 (the gear reduction box is a prior art, and the specific structure is not described here). The splines on the output shafts drive the first drum and the second drum to rotate synchronously, and then the friction force drives the wire rope wrapped in the groove of the drum to lift or the heavy objects below. When the capstan needs to change speed or reverse direction, the speed regulation and lifting and lowering functions can be performed by controlling the speed or direction of the servo motor.

[0035] The utility model has fully described a capstan driven by a pure electric servo motor. The transmission mechanism realizes stepless speed regulation and flexible reversing of the capstan through the drive and control of the servo motor, which solves the problems of serious pollution and poor maneuverability of the diesel engine driven and manually operated gearbox of the traditional motorized capstan. The overall structure of the capstan is reasonable, the operation is convenient, and the layout is more compact.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
