Vertical shaft hanging scaffold stabilizing device

Abstract

The invention relates to a vertical shaft hanging scaffold stabilizing device, belonging to a pit shaft construction hanging scaffold of a vertical shaft. The scaffold stabilizing device comprises a base plate, support seats, a connecting rod, an adjuster and a rubber wheel. The base plate is provided with two support seats, wherein one support seat is connected with the connecting rod, the adjuster is arranged between the connecting rod and the other support seat, and the connecting rod is connected with the rubber wheel. An upper-layer scaffold and a lower-layer scaffold of the hanging scaffold are respectively provided with four scaffold stabilizing devices. When in work, the solid rubber wheel and the scaffold stabilizing devices tightly support the shaft wall, so the hanging scaffoldcannot shake in the annular space. The vertical shaft hanging scaffold stabilizing device has the advantages that: firstly, the device can be repeatedly used has simples processing and convenient installation and use, saves processing materials and the capital and is free from manual operation and control on the hanging scaffold when the hanging scaffold is lifted; secondly, the device can not only stabilize the hanging scaffold, but also can be used for adjusting the gap between a hanging bucket and a horn so as to ensure that the hanging bucket has enough safe distance in the running process; and thirdly, the device creates the conditions for quick construction of the vertical shaft, saves labor force and physical resource, is safe and reliable and shortens the circulation time.

Description

technical field [0001] The invention relates to a shaft construction hanging plate, in particular to a vertical shaft hanging plate stabilizing device. Background technique [0002] At present, in order to speed up the construction speed and the safety of employees during the drilling of shaft shafts, hanging pans are installed in most of the well shafts, and central rotary rock grabbers are installed on the hanging pans. Since the hanging plate is suspended in the wellbore, during the use of the hanging plate during drilling, the hanging plate and the wellbore collide and damage each other, especially as the wellbore extends downward, the hanging plate also extends downward with the wellbore. Liftable function. [0003] In order to avoid the collision between the suspension plate and the shaft, the screw jacks, lead screws, wooden brakes and other stabilization devices used on the vertical shaft construction suspension plate can only be used once, and the reuse rate is low...

AI Technical Summary

Problems solved by technology

[0003] In order to avoid the collision between the hanging plate and the shaft, the screw jacks, screw, wooden brakes and other stabilizing devices used on the vertical shaft construction hanging plate can only be used once, and the reuse rate is low

It is easy to bend and deform during use, and it needs to be replaced frequently. During the construction of a wellbore, it needs to be replaced several times.

The lifting and lowering of the suspension plate will damage the surface quality of the shaft wall, and manual manipulation and control are required, and the safety performance is unreliable, and parts such as screw jacks, lead screws, and wooden brakes are easy to fall from the gap between the suspension plate and the shaft wall to the head, causing damage Construction workers
