Novel vertical shaft excavating vehicle

Abstract

The invention discloses a novel vertical shaft excavating vehicle. The novel vertical shaft excavating vehicle comprises a chassis part and a top-entry part, wherein the chassis part comprises a power and heat dissipation system, an underframe and a supporting leg system; the top-entry part comprises a telescopic arm assembly, a luffing mechanism, a bendable grab bucket mechanism, a high-pressure water spray device and a hydraulic and electrical control system. Stagnating objects within a certain turning radius range in the vertical direction of a vertical shaft can be grabbed out of the shaft, stagnating objects of an underground pipe network located within a certain range close to the vertical shaft to be dredged and vertically communicated with the vertical shaft are grabbed for dredging, and the vertical shaft can be dredged by 360 degrees in an all-around mode without a dead angle; after the vertical shaft is preliminarily dredged through a grab bucket, the high-pressure water spray device integrated on an excavating vehicle body is used for high-pressure water spraying to thoroughly dredge the drainage pipe network.

Description

technical field [0001] The invention belongs to the technical field of dredging equipment for shafts, and in particular relates to a novel shaft dredging vehicle. Background technique [0002] At present, silting often occurs in the inspection wells of urban drainage pipes, and at this time, it is necessary to use a shaft excavator to carry out shaft dredging. Existing shaft excavation vehicle is made up of automobile chassis, power and cooling system, underframe and outrigger system, hydraulic pressure and electric control system, luffing mechanism, telescopic arm assembly, grab mechanism. Utilize the automobile chassis with self-maneuvering ability, drive the car to the vicinity of the shaft to be dredged, open the outriggers, assist the chassis to support the weight, operate the control system, and vertically lower the grab mechanism installed on the telescopic arm along the shaft. The opening and closing of the bucket realizes digging and dredging operations. [0003] ...

AI Technical Summary

Problems solved by technology

[0003] However, the blockage of the shaft is often accompanied by the blockage of the underground pipe network that is vertical and connected to the shaft and close to the shaft to be dredged within a certain range. It is impossible to carry out all-round dredging work on the shaft without dead ends

[0004] In addition, if the shaft is blocked, the purpose of completely dredging the drainage pipe network cannot be achieved only by grabbing the blocked silt.
