Vehicle-mounted shelter telescopic suspension arm

Abstract

The vehicle-mounted shelter telescopic suspension arm comprises a fixed frame, a movable frame, a sliding guide rail combination, a motor speed reducing unit, a front double-drum winch, a rear double-drum winch, a first electric push rod, a second electric push rod and a hand-cranking transmission case, the movable frame is embedded into the fixed frame, and the outer side of the movable frame is connected with the inner side of the fixed frame through the sliding guide rail combination. A motor speed reducer is fixed to the middle of a groove-shaped bottom plate, the two ends of a worm wheel shaft of the motor speed reducer are fixedly connected with a front double-drum winch and a rear double-drum winch respectively, and the upper side of the rear end of a first electric push rod is fixed below one end of a groove-shaped transverse plate; the rear end of the second electric push rod is fixed below one end of a rear connecting transverse plate of the fixing frame, and one side of the upper portion of the motor speed reducing unit is connected with one side of a hand-cranking transmission box fixed to the groove-shaped bottom plate. Precious use space in the vehicle-mounted square cabin is not occupied, the space utilization rate of the vehicle-mounted square cabin is obviously increased, the structure is compact, use is rapid and efficient, the use cost is low, and the problem that equipment or heavy objects outside the cabin are hoisted into the cabin is solved.

Description

technical field [0001] The invention relates to a special hoisting device for a vehicle-mounted square cabin, in particular to a special hoisting device installed on the inner side of the cabin roof, which can be pulled out of the cabin door when in use, and can be retracted into the inner side of the cabin roof when not in use. Spreader technology. Background technique [0002] The vehicle-mounted shelter is mounted on the vehicle chassis, and is equipped with various special equipment. The personnel in the cabin can work with the moving vehicle, or use it after the vehicle is driven to the field and unload the shelter. It has strong mobility and has been widely used in Communication command, emergency rescue and military field operations. According to the use and maintenance requirements, the equipment or heavy objects in the vehicle cabin need to be unloaded or loaded, and the loading and unloading of heavy equipment or heavy objects by manual labor is time-consuming and...

AI Technical Summary

Problems solved by technology

According to the use and maintenance requirements, the equipment or heavy objects in the vehicle shelter need to be unloaded or loaded, and the heavy equipment or heavy objects are loaded and unloaded by manpower, which is time-consuming and labor-intensive

It is inconvenient and costly to use a truck crane for loading and unloading, so a special spreader that is installed in the car shelter and stable and reliable is needed
