The lifting assembly includes a cover, with sprockets rotatably installed at both ends of the cover. The sprockets are located on both sides of the car, and both sprockets are engaged with a plate chain. One end of the plate chain is fixedly connected to the bottom of the support column on one side of the car, and after engaging with the top of the sprocket on the same side and the bottom of the sprocket on the other side, the other end is fixedly connected to the top of the support column on the other side of the car.

[0005] Furthermore, two sets of sprockets are provided in the housing, and the two sets of sprockets are arranged in the opposite direction to the plate chain.

[0006] Furthermore, the cover is provided in multiple sets at the bottom of the car, and a fixed frame is provided at the bottom of the car. A hydraulic motor is installed on the fixed frame, and the output end of the hydraulic motor is fixedly connected to a connecting rod. The connecting rod is fixedly connected to multiple sprockets on one side of the car.

[0007] Furthermore, the sprockets at both ends of the cover rotate coaxially with the first bevel gear, the two first bevel gears mesh with the second bevel gear respectively, and the two second bevel gears are connected by a rotating shaft, which is rotatably installed at the bottom of the car.

[0008] Furthermore, the bottom of the car is equipped with a tilt sensor and an infrared sensor, which are connected to a hydraulic motor and an alarm device.

[0009] Furthermore, sliding blocks are provided on both sides of the car, and the sliding blocks are movably connected to the vertical sliding grooves on the support columns.

[0010] Furthermore, an anti-fall cylinder is provided at the bottom of the car, and the output end of the anti-fall cylinder is connected to a limiting block.

[0011] The beneficial effects of this utility model are that the hydraulic motor drives multiple sprockets to rotate synchronously through connecting rods and bevel gear sets. Through the meshing of multiple sets of sprockets with plate chains, the car is driven to rise and fall, enhancing the stability of the lifting. When the infrared sensor detects that there is someone under the car, or the tilt sensor detects that the car is tilted due to heavy objects, the hydraulic motor stops running and issues a reminder through the alarm device, enhancing the safety of the freight elevator operation.

The lifting assembly includes a cover 3, with sprockets 4 rotatably mounted at both ends of the cover 3. The sprockets 4 are located on both sides of the car 1, and both sprockets 4 are engaged with a plate chain 5. One end of the plate chain 5 is fixedly connected to the bottom of the support column 2 on one side of the car 1, and after engaging with the top of the sprocket 4 on the same side and the bottom of the sprocket 4 on the other side, the other end is fixedly connected to the top of the support column 2 on the other side of the car 1.

[0020] Two sets of sprockets 4 are provided in the housing 3, and the two sets of sprockets 4 are arranged in opposite directions to the plate chain 5.
