Description

Technical Field

[0001] This utility model relates to the technical field of lifting and unloading devices, specifically a lifting and unloading device for a vehicle-mounted radar generator. Background Technology

[0002] Vehicle-mounted radar generators are typically diesel generators that support mobile use on vehicles or trailers. They are suitable for emergency power needs in field construction sites, radar vehicles, and other similar applications. Their function is to supply power to all electrical equipment (except the starter motor) when the engine is running normally.

[0003] Most existing vehicle-mounted radar generator lifting devices are single-electric driven. In the event of an unexpected power outage or equipment failure, the generator is prone to free fall, which can cause damage and endanger personal safety. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing vehicle-mounted radar generator lifting and unloading devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a vehicle-mounted radar generator lifting and unloading device. During use, a sling is passed through the generator and connected via a plug connector. Under the action of the drive motor, the first bevel gear rotates. The first and second bevel gears, in turn, drive the third gear to rotate. Under the action of the second chain, the second rotating shaft drives the second pulley to rotate, tightening the sling around it. The third and fourth gears, in turn, drive the first pulley to rotate in the opposite direction to the second pulley, tightening the sling on the other side. In the event of a power failure, the self-locking characteristic of the reducer is used to lock the motor, preventing it from becoming unsupported. Rotating the handle drives the second sprocket to rotate via the second gear. Under the action of the first chain, the second power input end of the reducer starts, driving the first bevel gear to rotate, thereby driving the lifting and unloading assembly. The accelerated gear reduces the operator's workload to some extent in manual mode.
