Hoisting mechanical arm for vertical shaft slag removal and using method of hoisting mechanical arm

Abstract

A hoisting mechanical arm for vertical shaft slag removal comprises a chuck and a rotating arm which are connected, a rotating base matched with the rotating arm is formed in the middle of the chuck, the rotating arm is rotationally connected to the rotating base, and the rotating base is rotationally connected to the chuck; the rotating arm comprises a first supporting arm and a second supporting arm which are rotationally connected, the first supporting arm is provided with a first driving piece connected with the end of the second supporting arm, and the rotating seat is provided with a driving motor connected with the first supporting arm; a rotary connecting piece is arranged at the end part of the second support arm, and a second driving piece connected with the rotary connecting piece is arranged on the second support arm; a slag removing shovel or a drill rod is arranged on the rotary connecting piece; compared with the prior art, by arranging the hoisting type mechanical arm, mechanical slag removal operation can be conducted in the vertical shaft, a slag removal shovel or a drill rod can be arranged on the rotating connecting piece according to needs, the mechanical arm can ascend and replace, descend to remove slag or drill holes, and better safety is achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical arms, in particular to a hoisting mechanical arm for removing slag in a shaft and a method for using the same. Background technique [0002] With the extension of the expressway network to the vast mountainous areas, a large number of long road tunnels have emerged, and the number of tunnels using vertical shaft ventilation is increasing. Under the pressure of operational ventilation and disaster prevention and relief, the diameter of road tunnel ventilation shafts is also increasing. The cost and safety issues of shaft construction are also becoming increasingly prominent. [0003] Among them, the shaft excavation technology of raising drilling rig method belongs to a new technology in the construction of ventilation shafts of highway tunnels. It has the advantages of fast construction speed, no special construction ventilation, convenient construction drainage, high project quality, low labor...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, manual slag removal is usually used in the process of excavating shafts by the raise drilling rig method. However, when the cross-sectional shaft size is large and the depth is deep, the manual slag removal method is labor-intensive and low in efficiency. , and there are certain security risks
