Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and specifically relates to a lifting device for an elevator. Background Art

[0002] The background and role of car lifts are very extensive and can be traced back to the development of the automobile manufacturing industry in the mid-20th century. During this period, the automobile industry and logistics industry developed rapidly, resulting in an increasing number of cars and an expanding scale. For production, repair and storage units, the work of safely moving a large number of cars and other vehicles from the ground to a higher position has become quite difficult. Since manual or manual methods are inefficient and dangerous, a new type of equipment is needed to solve this problem. The lift came into being.

[0003] The main function of the car lift is to lift the vehicle. It can easily lift the vehicle to a higher position for repair and maintenance of the vehicle, such as lifting the body, checking the chassis, etc. It can also operate in a narrow space, which greatly reduces the difficulty and time of the staff's work.

[0004] When the car lift encounters excessive resistance, support system failure or other abnormal conditions during operation, the lift may drop suddenly. If the car lift drops suddenly, it will cause mechanical damage to the vehicle and the structure of the car lift. If it touches the staff below during the descent, it will cause harm to the staff. In serious cases, it will cause safety accidents or casualties. Therefore, we propose a lifting device for the lift to avoid accidents. Utility Model Content

[0009] Preferably, an arc-shaped depression is provided on one side of the upper surface of the support plate.

[0010] Preferably, the number of the hydraulic cylinders is four.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the hoist body and the lifting arm form a complete hoist, the surface of the support plate is provided with a depression, so that the placement of the vehicle is more stable, and when the vehicle stops, it is lifted upward by the hoist. When the height of the hoist is determined, auxiliary lifting and protection are provided by the lifting structure. The frame is square-shaped and leaves enough construction space, avoiding space limitations during operation and not affecting the operation of the staff. Failures of the hydraulic system are usually easier to diagnose and repair than mechanical systems, and the design of the exposed frame makes it easier to replace the hydraulic cylinder, and also provides protection through the powerful thrust of the hydraulic cylinder. Moreover, the hoist and the lifting structure are driven by separate power. Even if the power system of the hoist fails, the lifting structure can still provide support and protection, which ensures that in an emergency, the car and the staff can be protected, and there will be no danger due to hoist failure, providing sufficient safety.
