Problems solved by technology

In order to facilitate the crane to carry out track laying and other operations, a certain lifting operation space is required at the construction site. For some construction sites with open ground and ample operating space, the crane can be used handy. For those special construction sites, such as urban Because of the circular shape of the light rail tunnel, it is very difficult for conventional lifting equipment to walk directly in it, not to mention the lifting operation on the track. In order to ensure that conventional cranes can carry out construction in it, it is often necessary Pre-construct two construction runways in the tunnel and dis

Abstract

The invention discloses a tunnel crane which comprises a beam frame. The beam frame includes an outer beam frame body and an inner frame beam body, the connecting end of the outer beam frame body is slidably connected with the connecting end of the inner beam frame body in a sleeving manner, a left driving roller is arranged at the support end of the outer beam frame layer, a right driving roller is arranged at the support end of the inner beam frame body, both the left driving roller and the right driving roller are connected to a driving device in a transmission manner, a beam frame retraction device is arranged on the beam frame, two ends of the beam frame retraction device are respectively hinged to the outer beam frame body and the inner beam frame body, and a movable winch is arranged on the beam frame. By the arrangement, the tunnel crane can travel in a tunnel directly for lifting operations, and the tunnel crane is reasonable in structural design and safe and reliable in use.

Description

technical field [0001] The invention relates to a construction machine, in particular to a crane used for laying a track in a tunnel. Background technique [0002] During the track construction process, the application of lifting equipment is essential in order to facilitate the movement and laying of the track. With the development of technology, various cranes for special construction environments and special construction needs have emerged, and quite a few of them are very mature, which greatly facilitates construction and plays a role in escorting the safety and progress of construction. In order to facilitate the crane to carry out track laying and other operations, a certain lifting operation space is required at the construction site. For some construction sites with open ground and ample operating space, the crane can be used handy. For those special construction sites, such as urban Because of the circular shape of the light rail tunnel, it is very difficult for co...
