[0022] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0023] See also Figure 1 , a vehicle maintenance rack provided in this embodiment includes:

[0024] A base, wherein a roller is installed on the bottom of the base and a column is arranged on the top;

[0025] A hanging frame 1, which is installed on the top of the column and is parallel to the ground;

[0026] A limit arm 2, one end of which is mounted on the hanging frame, and the other opposite end of which extends downward to form a connecting portion;

[0027] A positioning plate 3, the positioning plate is installed on the connecting portion, and a positioning hole 31 is opened on the positioning plate;

[0028] and a hoisting mechanism 4, the hoisting mechanism 4 comprises a hoist 41, a cable 42 and a clamp 43 for clamping the engine, the hoist is installed on a hoisting frame, one end of the clamp is a limit end, and the other opposite end is a hoisting end, the hoisting end is used to hoist the engine, and in this embodiment, the hoisting end is provided with a hook to facilitate the hoisting operation. The limit end can be inserted into the positioning hole and clamped with the positioning plate, one end of the cable is connected to the power output end of the hoist, and the other opposite end passes through the positioning hole and is connected to the limit end.

[0029] When the engine needs to be hoisted, the clamp 43 is pulled downward to allow the cable to extend downward through the positioning hole. At this time, since the cable is flexible, it is convenient to adjust the position and direction of the hook, so as to facilitate the hoisting of the engine. The hook is connected to the engine, and the winch is started. Under the action of the winch, the cable is continuously retracted, and the engine is lifted upward through the hook until the limit end is inserted into the positioning hole and is clamped with the positioning plate. At this time, the hook is fixed on the positioning plate and loses the freedom to swing left and right. It is convenient to prevent the engine from swinging left and right when the engine is transported, and it is convenient to prevent the engine from colliding with other equipment in the maintenance workshop and causing damage to the engine. A conical end is provided at the top of the limit end, which is convenient for inserting the limit end into the positioning hole. The cable of this embodiment is a flat lifting belt. It is convenient for the winch to reel in the cable. The cable includes a flat lifting belt body, and mesh fiber cloth is provided on both sides of the flat lifting belt body; a plurality of steel wire ropes are provided in the middle of the mesh fiber cloth. The mesh fiber cloth increases the stability of the lifting belt body, improves the wear resistance, and increases the structural stability of the steel wire rope while increasing the load-bearing capacity.

[0030] As a further improvement of the above technical solution, it also includes a fixed hollow tube 5 and a movable hollow tube 6; the fixed hollow tube is fixed on the hanging frame; one end of the movable hollow tube is sheathed on the bottom of the fixed hollow tube, and the other opposite end extends vertically downward and is connected to the positioning plate, and the movable hollow tube can slide in the fixed hollow tube along the vertical direction;

[0031] The limit arm 2 includes an upper swing arm 21 and a lower swing arm 22. The top of the upper swing arm is hinged to the hoisting frame, the top of the lower swing arm is hinged to the bottom of the upper swing arm, and the bottom of the lower swing arm is hinged to the positioning plate. The movable hollow tube slides up and down to facilitate adjusting the engine hoisting height.

[0032] As a further improvement of the above technical solution, the limit arm 2 also includes a motor 23. On the hoisting frame, the top of the upper swing arm is connected to the power output shaft of the motor. When the hoisting height needs to be adjusted, the motor 23 is started, the upper swing arm rotates, and the positioning plate is driven to move up and down through the lower swing arm, so as to facilitate the adjustment of the hoisting height.

[0033] As a further improvement to the above technical solution, the lower swing arm includes two arm bodies, and the two arm bodies are respectively located on both sides of the upper swing arm, so as to increase stability.
