Working platform load overrun protection device of bridge inspection vehicle and control method thereof

Abstract

The invention discloses a working platform load overrun protection device of a bridge inspection vehicle. The device comprises an elevating tower, a working platform and a protective frame, an installation seat is fixed at the bottom of the elevating tower, the working platform is movably installed on one side of the installation seat through a rotary shaft, the protective frame is fixedly supported on the edge positions of two sides of the top of the working platform through a supporting frame, a sliding groove is formed in the protective frame, a supporting plate is fixed on the end, away from the installation seat, of the top of the working platform, a driving motor is installed on the top of the outer side of the supporting plate through a bolt, the output end of the driving motor penetrates through the supporting plate and is fixedly connected with a lead screw, a driving block is movably installed on the lead screw, and a sliding block matching with the sliding groove is arrangedat the bottom of the driving block. By means of the device, a load bearing point of the working platform is monitored in real time, loads borne by the working platform are accurately monitored to strictly prevent the load overrun of the working platform from occurring and put an end to the occurrences of the phenomenons of the fracturing of the platform and the like, and therefore the safety of aworker and equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of high-altitude operation safety of construction machinery, in particular to a load overrun protection device for a workbench of a bridge inspection vehicle and a control method thereof. Background technique [0002] The bridge inspection vehicle is currently the most important equipment in the inspection and maintenance of highway bridges. It can provide a flexible and mobile manned platform, which is convenient for personnel to carry out all-round inspection and maintenance of bridges. [0003] However, in the actual use process, the bridge inspection vehicle is overloaded from time to time, resulting in serious phenomena such as the platform falling. An effective device or measure is urgently needed to prevent the bridge inspection vehicle from overloading and ensure the safety of man and machine. The overload protection of the existing bridge inspection vehicle mainly collects data by installing weighin...
