Running mechanism for suspension type bridge inspection trolley

Abstract

The invention relates to a running mechanism for a suspension type bridge inspection trolley, and belongs to the field of running devices of the suspension type bridge inspection trolley. The running mechanism is innovative in structure and concise in mode, a left running wheel and a right running wheel are symmetrically installed on the upper surfaces of the lower edges of the two sides of a running track, and connected with an n-shaped frame hinge pin of a main frame through connecting rods and connecting bases; a driving mechanism is composed of a motor and a manual chain driving mechanism, the motor and the manual chain driving mechanism are correspondingly connected with wheel shafts of the two running wheels respectively, the motor or the manual chain driving mechanism is controlled to achieve driving running of the running wheel on the corresponding side and driven running of the running wheel on the other side, running of the running mechanism which is driven by the motor or the manual chain driving mechanism and carries the main frame along the running track is achieved, when the motor has temporary failures in work, running can be completed through manual driving by pulling a chain, and then the stable and safe running work of the running mechanism can be guaranteed. The running mechanism is simple, safe and reliable in structure, convenient to install, easy to disassemble and replace and convenient to maintain.

Description

technical field [0001] The invention relates to a running mechanism for a suspended bridge inspection vehicle, which belongs to the field of running equipment for a suspended bridge inspection vehicle. Background technique [0002] The bridge inspection vehicle is a working platform provided for bridge inspectors during the inspection process. It is equipped with bridge inspection instruments and is a special engineering vehicle for mobile inspection or maintenance operations. It can move the position at any time, and can safely, quickly and efficiently allow inspectors to enter the working position for mobile inspection or maintenance operations, without affecting traffic during work. [0003] The working area of ​​the suspended bridge inspection vehicle is the bottom or side of the bridge. At present, the general-purpose bridge inspection vehicle is integrated with the running device. The existing inspection vehicle running mechanism widely used in rivers and seas adopts ...

AI Technical Summary

Problems solved by technology

At present, the general-purpose bridge inspection vehicle is integrated with the running device. The existing inspection vehicle running mechanism widely used in rivers and seas adopts a suspended structure. Provide power to drive the running wheels on both sides at the same time, and the motor shaft is fixedly connected to the shafts driving the running wheels on both sides. Although this running mechanism can meet the requirements of moving the position at any time, its structure is complex and inconvenient to disassemble and replace, and it needs an external power supply. , when the motor fails during work, the inspection vehicle cannot be returned to the original parking point for maintenance
