Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a construction device for lifting vertical shafts. Background Technology

[0002] Shaft construction is an engineering construction technology that involves vertically excavating and building shaft structures underground or in mountains. Its core purpose is to provide a vertical passage for personnel, materials, and equipment to enter and exit underground projects such as tunnels, subway stations, mine roadways, underground caverns, and hydropower station pressure pipelines. It is mainly used in mining engineering, transportation tunnels, water conservancy and hydropower, municipal engineering, resource exploration, and other fields. It is a technically complex and high-risk underground engineering operation.

[0003] Chinese patent CN222374137U discloses a vertical shaft soil removal and lifting device, which includes two side frames connected by a crossbar. The crossbar is connected to a lateral movement mechanism, which is connected to a winch. A hoisting rope is installed on the winch, and a slag frame is installed at the end of the hoisting rope. In actual use, the soil material at the bottom of the shaft is placed in the slag frame, and the winch is started to drive the hoisting rope to rise, thereby completing the removal and lifting of the soil material from the bottom of the shaft.

[0004] However, the aforementioned technologies have the following drawbacks: if the earthwork material is not evenly distributed in the slag frame at the beginning, the slag frame itself will tilt and deflect during the subsequent lifting of the earthwork material. On the one hand, this will cause the earthwork material in the slag frame to spill out; on the other hand, the deflection of the slag frame itself is very likely to cause collisions between the slag frame and the shaft wall during the lifting process. During the shaft construction process, the protection of the shaft wall is crucial. If the slag frame containing earthwork waste collidees with the support structure on the shaft wall, it is very likely to cause permanent damage to the support structure on the shaft wall, posing a serious safety hazard to the shaft construction.

The crane 11 drives the slag frame 2 to move upward. During the upward movement, the level of the slag frame 2 is detected by the detection component 8. When the slag frame 2 is detected to have an angular deviation, the drive component 4 drives the mounting frame 3 to move, which in turn drives the counterweight 9 to move. This makes the angular deviation of the counterweight 9 and the slag frame 2 cancel each other out, so that the slag frame 2 is in a horizontal state during the lifting process, which can effectively improve the balance and stability of the slag frame 2 during the lifting process.
