Description

Technical Field

[0001] The utility model relates to the field of double-drum winches, and more specifically, to a double-drum winch. Background Art

[0002] A winch generally refers to a motorized winch. A motorized winch is a construction tool for erecting high-voltage transmission lines in the air and laying underground cables. It can smoothly and conveniently perform hoisting and traction operations such as erecting iron towers and erecting conductors (ground wires) under various complex conditions. Motorized winches are divided into diesel motorized winches and gasoline motorized winches, and are also divided into hand-held and belt-wheel types. They are widely used in the construction of power and postal lines for erecting poles, motorized wire laying, and tight wire. They can also be used for hoisting and towing heavy objects in places such as construction sites and docks. They are suitable for places without electricity in the wild, are flexible to use, and a double-drum winch has two drums that can rotate synchronously to realize one wire winding and one wire unwinding, with higher operation efficiency.

[0003] For example, the patent application No. 202321633607.4 discloses a double-drum motorized winch, which includes an internal combustion engine, a control box rotatably connected to the internal combustion engine, a drum rotatably connected to the output bearing of the control box, a transmission device connected to the output bearing, a fixing member connected to the transmission device. The transmission device includes two gear sets, each gear set includes two parallel gear plates, the gear set is sleeved on the corresponding output bearing, two chains are meshed and connected between the two gear sets, and a drum is connected between the two chains. The utility model has an automatic rope threading function. One end of the traction rope is fixed by a rope threading block and a bolt, and the transmission device is rotated to wind the traction rope in circles, eliminating the need for manual running back and forth to thread and pull the rope, saving time and effort. As long as the drum is rotated through the control box, the transmission device will rotate synchronously, with simple operation and convenient use.

[0004] In the existing double-drum winches, due to their more complex structure and greater weight, a driving vehicle body is generally installed for auxiliary movement during use. To maintain stable use, the take-up drum and the vehicle body are generally in a straight line and perpendicular to the wire travel to increase the stability of the device. However, in the above method, during the initial stage of gear shifting and the application of force for lifting heavy objects, the vehicle body will still swing, and even operational errors may occur. If the object is too heavy, it will cause the vehicle body to shift and pose a danger. Summary of the Utility Model

Auxiliary support blocks 6 are hinged at both ends of the loading plate 2. The auxiliary support blocks 6 are in contact and cooperation with the bottom frame 1.

[0023] In the present invention, the two frames 1 and the loading plate 2 form a supporting vehicle body. The double-drum winch 5 is fixedly installed in the middle of the loading plate 2. When in use, one end of the steel wire is first wound around the drum part of the double-drum winch 5 for a specified number of turns and fixed, and then the double-drum winch 5 is started to drive the steel wire to wind up, so as to realize the vertical lifting of the object at the other end. And when it needs to be moved, the two vertical driving members 4 are started to drive the loading plate 2 to vertically rise with the frame 1 as the support, driving the double-drum winch 5 to rise. At this time, the bottom of the loading plate 2 is off the ground, so that the two frames 1 can move smoothly. And as the loading plate 2 rises, the two auxiliary support blocks 6 swing downward under the action of gravity until they are vertical. At this time, the vertical driving member 4 stops rising and descends a certain distance, so that the auxiliary support blocks 6 are in contact with the frame 1 to realize auxiliary support, improving the stability of the loading plate 2 during movement. Thus, the device has the advantages of being convenient to move, having better stability when in contact with the ground during use, and higher use safety, solving the problems in the prior art that during the initial stage of force application for equipment gear shifting and heavy object lifting, the vehicle body will still swing, and even operation errors may occur, and when the object weight is too large, the vehicle body will shift and cause danger.

[0025] In the present utility model, by starting the vertical hydraulic cylinder 41 to drive the top plate 42 to rise vertically, the connecting rod 43 and the bottom carrier plate 2 are driven to rise with the vertical support block 3 as the support, so as to realize the smooth lifting and adjustment of the carrier plate 2, with good stability and more flexible use.

[0026] Please refer to Figure 1 , wherein: a positioning groove 7 for vertically inserting the auxiliary support block 6 is provided on the vehicle frame 1.
