Abstract
Description
Technical Field
[0001] The utility model relates to a hoisting device for a tractor cab, belonging to the technical field of cab hoisting auxiliary equipment. Background Technique
[0002] With the continuous development of agriculture, tractors play a crucial role in agricultural development due to their high operation efficiency, simple operation, good driving comfort, adjustable strength, strong adaptability and other advantages. As an important operation and control mechanism of the tractor, the cab is difficult to hoist during the hoisting process due to its large weight and irregular shape, which seriously affects the work efficiency and line balance of the assembly operation.
[0003] The traditional cab hoisting method adopts the form of a crane plus a sling. In this method, the sling is passed through the inside of the cab, and then the crane is used to lift the sling (the sling leans against the inner side of the cab roof) for assembly. This method is relatively cumbersome to operate, takes a long time, affects the operation efficiency, and is easy to damage the interior trim of the roof, affecting the quality of the cab. In addition, at least three people are required to cooperate to complete this assembly method, and the cost is relatively high. Content of the Utility Model

Two first hooks are arranged below the left longitudinal beam, and two second hooks are arranged below the right longitudinal beam. The first hooks are installed on the left longitudinal beam through an adjusting mechanism, and the adjusting mechanism adjusts the position of the first hooks on the left longitudinal beam. The second hooks are installed on the right longitudinal beam through slings. A lifting ring is arranged on the cross beam, and the lifting ring is installed on the cross beam through a second lifting plate.
[0007] The beneficial effects of the utility model are as follows: The utility model can adjust the position of the first hooks through the adjusting mechanism according to the weight and shape of the cab, so as to adapt to different cabs. The center of gravity of the hoisting bracket is adjusted through the second lifting plate, so as to balance the cab, and it is applicable to a variety of models. The utility model replaces the traditional hoisting method of a crane plus a sling, has higher safety, simpler operation method, saves manpower, and can better protect the interior trim of the cab from damage through the first hooks and the second hooks.
[0008] On the basis of the above technical solution, the utility model can also make the following improvements:

[0011] Furthermore, the adjusting mechanism further includes a U-shaped connecting piece. The sling is mounted in the middle of the U-shaped connecting piece. Pin holes are provided at both ends of the U-shaped connecting piece. The U-shaped connecting piece is mounted on the mounting hole of the first suspension plate through a pin shaft.
[0012] The beneficial effect of adopting the above further technical solution is that the connection of the U-shaped connecting piece is convenient, easy to disassemble and assemble, and convenient to adjust the installation position.
[0013] Furthermore, the second hook is an eye hook.
[0014] The beneficial effect of adopting the above further technical solution is that the eye hook can realize the quick connection and locking between the second hook and the hoisting ring at the rear of the cab, avoid the second hook from falling off, and improve the stability and safety of hoisting.
[0015] Furthermore, a plurality of balance holes are provided on the second suspension plate, and the lifting ring is mounted on the balance holes of the second suspension plate.
[0016] The beneficial effect of adopting the above further technical solution is that by providing a plurality of balance holes on the second suspension plate, the position of the lifting ring on the cross beam can be adjusted, so that different balance holes on the second suspension plate can be selected according to the weight and shape of the cab to better balance the cab and be applicable to cabs of various weights.
[0017] Furthermore, the lifting ring is mounted on the mounting hole of the second suspension plate through a shackle.
[0018] The beneficial effect of adopting the above further technical solution is that the lifting ring can be quickly installed and locked by using a shackle. Description of the Drawings
