Description

Lifting support for pi-shaped beam Technical Field The utility model relates to the technical field of transfer equipment, in particular to a lifting bracket for pi-shaped beams. Background In mining, tunnel construction and large-scale infrastructure construction, pi-shaped beams are used as a key supporting member and widely applied to temporary or permanent supporting of tunnel roofs and side walls. The unique pi-shaped structure (the top cross beam and the extending plates at the two sides of the bottom) endows the lifting device with excellent bearing capacity, but also provides requirements for the lifting process. The traditional hoisting mode generally adopts a steel wire rope bundling to realize a fixed hoisting method, however, the traditional hoisting mode has some technical problems in the practical application process. For example, in the binding process of the steel wire rope, the pi-shaped beam is easily inclined due to uneven friction force distribution at each part. Particularly, when long-distance transportation or high-altitude operation is carried out, the possibility of shaking of the beam body is greatly increased, and high safety risks exist. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the lifting support for the pi-shaped beam, which not only can facilitate a worker to lift and transport the pi-shaped beam to a use position, but also can improve the stability of the device when the pi-shaped beam is moved. The utility model is realized through the following technical scheme, the lifting bracket for the pi-shaped beam is provided, the lifting bracket comprises a U-shaped hanging body, vertical plates are fixedly connected to the left side wall and the right side wall of the U-shaped hanging body, two cross bars are arranged on the inner side walls of the vertical plates, the two cross bars are respectively positioned at the front side and the rear side of the U-shaped hanging body, the cross bars transversely extend along the left-right direction and pass through the vertical plates, two vertical plates transversely distributed along the front-rear direction are fixedly connected to the inner side walls of the cross bars, rotating wheels rotationally connected with the front vertical plates and the rear vertical plates are arranged at the inner sides of the cross bars, a connecting plate is fixedly connected to the outer side walls of the cross bars, springs fixedly connected with the connecting plate and the vertical plates are sleeved on the cross bars, a limiting rod is fixedly connected to the inner side walls of the connecting plate, one end of the limiting rod far away from the connecting plate transversely extends through the vertical plates along the left-right direction and is aligned with the inner side walls of the rotating wheels, the bottoms of the limiting rod are aligned with the inner side walls of the rotating wheels, the tops of the limiting rod are aligned with the horizontal axes of the rotating wheels, and the vertical distances between the limiting rod and the inner side walls of the rotating wheels are consistent with the vertical height of the pi-shaped hanging body.
