Profile lifting equipment

Abstract

The invention provides profile lifting equipment which comprises a walking device, a lifting device, a first arm, a second arm and a limiting device, and a walking platform is arranged at the top of the walking device; the lifting device comprises a lifting assembly and a lifting platform, and the lifting assembly is arranged between the walking platform and the lifting platform; a first bracket is arranged at one end of the first arm, the other end of the first arm is assembled on the lifting platform and can swing towards one side of the lifting equipment, a second bracket is arranged at one end of the second arm, and the other end of the second arm is assembled on the lifting platform and can swing towards the other side of the lifting equipment; the limiting device comprises a guide rail and a clamping piece, the guide rail is arranged on the lifting platform, the clamping piece is arranged on the guide rail and can move in the extending direction of the guide rail, and the clamping piece has a first form and a second form. According to the profile lifting equipment, lifting of shed erecting profile is facilitated, the labor intensity of workers is reduced, the situation that production is affected due to the fact that a miner-bolter is occupied for a long time in the prior art is avoided, and the mine production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shed support, in particular to a profile lifting device. Background technique [0002] In order to ensure the safety of underground roadway construction, scaffolding operations are required where the roof conditions of the roadway are poor and where cracks in the roof are developed. During scaffolding work, it is necessary to fix steel beams on the roof of the roadway. In related technologies, the steel beams need to be lifted to the roof of the roadway with the help of a roadheader. In this respect, there are many workers, and the roadheader is not easy to accurately control due to its large size. During the scaffolding process, it is very easy to cause personal injury and there are safety hazards such as falling objects from high altitudes. On the other hand, each scaffolding operation takes a long time, which affects normal excavation, and the bolter cannot be repaired normally, especially when the equ...

Problems solved by technology

During scaffolding work, it is necessary to fix steel beams on the roof of the roadway. In related technologies, the steel beams need to be lifted to the roof of the roadway with the help of a roadheader. In this respect, there are many workers, and the roadheader is not easy to accurately control due to its large size. During the scaffolding process, it is very easy to cause personal injury and there are safety hazards such as falling objects from high altitudes. On the other hand, each scaffolding operation takes a long time, which affects normal excavation, and the bolter cannot be repaired normally, especially when the equipment is faulty. When hidden dangers and scaffolding operations occur at the same time, production will be severely restricted, which is not conducive to safe and efficient scaffolding operations
