Box culvert crane working under low clearance conditions

Abstract

The invention relates to a box culvert crane working under the low clearance conditions, comprising a longitudinal moving bracket, a longitudinal moving trolley, a horizontal moving bracket, a horizontal moving trolley, a lifting device, a rotary device and a box culvert support, wherein the longitudinal moving trolley is arranged on the longitudinal moving bracket and connected through the horizontal moving bracket, and the horizontal moving trolley is arranged on the horizontal moving bracket; the rotary device is arranged on the box culvert support, and the lifting device is connected to the horizontal moving trolley and the rotary device respectively; and the box culvert support is in a U-shaped structure. With such structure, the box culverts can be installed under the low clearance conditions; since the box culverts are not required to rotate on a transport vehicle, the requirements for the transport vehicle are reduced, so a plurality of box culverts can be transported at a time, and the transport efficiency of the box culverts is improved; the installation of the box culverts and the tunneling of a shield machine can be implemented synchronously, so that the construction period and cost can be reduced greatly.

Description

technical field [0001] The invention relates to the technical field of box culvert installation, in particular to a box culvert crane working under low headroom conditions. Background technique [0002] In today's society, in order to develop a variety of traffic, tunnel engineering is getting more and more attention. In the design of tunnel sections, especially for tunnels with larger diameters, box culverts are often designed below the tunnel section as pipes for drainage, power, communication, etc. Road installation space. According to different plans, the size and shape of the box culverts are also different. If the headroom height is small due to the large height of the box culvert, it will directly affect the transportation and assembly of the simultaneous box culvert construction, and even cannot be assembled synchronously. However, if synchronous box culvert construction is not carried out, the construction period and cost will be greatly increased. At the same tim...

AI Technical Summary

Problems solved by technology

According to different plans, the size and shape of the box culverts are also different. If the headroom is small due to the large height of the box culvert, it will directly affect the transportation and assembly of the synchronous box culvert construction, and even cannot be assembled synchronously.

However, if synchronous box culvert construction is not carried out, the construction period and cost will be greatly increased

At the same time, due to the problem of transportation distance, the longer the tunnel, the lower the efficiency in the later stage of construction, and the transportation efficiency of box culverts and accessories is also a big problem
