Abstract

The invention discloses an overload prevention control method and device for a working platform of a bridge inspection vehicle. The device includes: a first pin sensor, a second pin sensor, an overload prevention controller and an alarm device, wherein: the first pin sensor is used to detect the force Fa of the first detection point a along the axial direction of the retractable oil cylinder , wherein the first detection point a is the hinge point between the retractable oil cylinder and the lifting tower; the second pin sensor is used to detect the force Fb of the second detection point b along the vertical direction, wherein the second detection point b is the hinge point of the working platform and the lifting tower; the anti-overload controller is used to obtain the current load of the platform according to Fa and Fb; and compares the current load of the platform with the allowable load of the platform; the alarm device is used to The comparison result will give an alarm. The invention can accurately monitor the load of the working platform, strictly prevent the load of the working platform from exceeding the limit, prevent the vehicle from overturning, the platform is broken, and the like, thereby ensuring the safety of people and equipment.

Description

technical field [0001] The invention relates to the technical field of high-altitude operation safety of construction machinery, in particular to an overload prevention control method and device for a working platform of a bridge inspection vehicle. Background technique [0002] With the development of traffic engineering, more and more bridges are being built, and regular maintenance is required, resulting in a heavy workload. The bridge inspection vehicle is a powerful auxiliary tool in the bridge maintenance process. It can provide a flexible and mobile manned platform, which is convenient for personnel to carry out all-round maintenance of the bridge. However, in the actual use process, the bridge inspection vehicle is overloaded from time to time, resulting in serious phenomena such as vehicle body tipping and platform falling. An effective device or measure is urgently needed to prevent the bridge inspection vehicle from being overloaded and ensure human-machine safety...
