Shield folding and unfolding device

Abstract

The invention discloses a shield folding and unfolding device. The folding and unfolding device comprises a first sliding mechanism arranged between the back face of an upper shield and the front face of a middle shield, and a second sliding mechanism arranged between the back face of the middle shield and the front face of a lower shield, the bottom end of a first translation driving mechanism is arranged on the back face of the middle shield, the driving end of the first translation driving mechanism is connected with the back face of the upper shield, and the telescopic movement of the first translation driving mechanism drives the upper shield to translate on the front face of the middle shield; the bottom end of a second translation driving mechanism is arranged on the back face of the lower shield, the driving end of the second translation driving mechanism is connected with the back face of the middle shield, and the telescopic movement of the second translation driving mechanism drives the middle shield to translate on the front face of the upper shield. According to the shield folding and unfolding device, relative translation of the upper shield, the middle shield and the lower shield is achieved to achieve the folding and unfolding states, folding and unfolding of shields are rapidly and automatically completed, the efficiency is improved, and manpower and time are saved. Meanwhile, the safety of personnel in a dangerous environment is improved. The size of the folded shields is reduced, the occupied space is reduced, storage and transportation are facilitated, and the overall passing ability can be improved.

Description

technical field [0001] The invention relates to the technical field of shield attitude control, in particular to a shield retracting device suitable for robots. Background technique [0002] In order to improve the overall mobility, passability, and concealment of the shield mechanism, it is necessary to reduce the space occupied by the shield when needed. The existing shield is a fixed structure that cannot be automatically extended and retracted. It can only be installed and disassembled by external personnel to realize the erection and retraction of the shield. In a dangerous environment, the process of personnel disassembling and assembling the shield may bring safety problems to it. In addition, existing shields are basically installed and disassembled manually. For small shields, the workload of manual installation and disassembly is acceptable, but for large shields, it takes a lot of manpower and time. Therefore how to realize the automatic retraction of the shield ...
