An electric skid steer truck

Abstract

The invention provides an electric load-carrying sliding trolley, which adopts numerical automatic control, cooperates with the existing I-beam guide rail or other guide rails, drives the Bailey beam to slide, and realizes the synchronous transportation of high-altitude spans. The device of the invention is simple to operate, does not require manpower for traction control, reduces the risk of high-altitude operations, reduces labor costs, can realize precise synchronous control on both sides, and contains an intelligent speed control system, intelligently adjusts the sliding speed, and can realize horizontal direction. Accurate transportation reduces the risk of the trolley slipping off the track. An obstacle detection device is installed to automatically detect obstacles. When an obstacle is detected, it will automatically alarm and control the brakes of the trolley, reducing the possibility of the trolley rolling over, which greatly reduces the The risk of accidents improves the safety of the demolition of the Bailey beam support, which is safe and reliable with high demolition efficiency, and can ensure the construction quality and save the construction period.

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.
