Electric sliding loading trolley

Abstract

The invention provides an electric sliding loading trolley. The electric sliding loading trolley adopts numerical automatic control, cooperates with existing I-shaped steel guide rails or other guiderails and drives a Bailey beam to slide, and high-altitude-span synchronous transportation is achieved. According to the device, operation is easy, manual traction control is not needed, the high-altitude operation danger is reduced, the manual cost is reduced, and two-side precise synchronous control can be achieved; in addition, the electric sliding loading trolley comprises an intelligent speedcontrol system, the sliding speed can be intelligently controlled, precise transportation in the horizontal direction can be achieved, and the risk that the trolley slides out of a track is reduced;and an obstacle detection device is arranged, obstacles can be automatically detected, automatic alarming is conducted and the trolley is controlled to be braked when the obstacles are detected, the trolley rollover probability is reduced, the accident risk is greatly reduced, the Bailey beam bracket dismantling safety is improved, the safety and the reliability are achieved, the dismantling efficiency is high, the construction quality can be guaranteed, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, in particular to an electric sliding trolley. Background technique [0002] Bailey beams are mostly used in engineering construction. They are truss beams composed of Bailey frames. Flower windows are mostly used as connecting components between Bailey frames and fixed with bolts. Because of their rapid erection and strong mobility, they are mostly used in rivers, Erection of simple bridges on cliffs is an important support system in the construction of many cast-in-place continuous box girders across highways and rivers. [0003] When dismantling construction work after using the Bailey beam at high altitude, the most commonly used construction method is to manually control the winch for traction to realize horizontal transportation. After the Bailey beam is moved to the outside, the Bailey beam is hoisted and dismantled by a crane. , such as the patent document CN208668283U di...

AI Technical Summary

Problems solved by technology

However, due to the high height, large volume and limited operating space of the Bailey beam, manual control of the horizontal traction is difficult to operate. Due to the large weight of the Bailey beam, the inertia of the Bailey beam is large when it is driven, and it is difficult to control, and it is prone to rollover Or the problem of rushing out of the end of the slide rail is very dangerous. In addition, manual control of traction also has problems such as low demolition efficiency and affecting the progress of the construction period.
