Suspension bridge tunnel type anchorage cable crane and construction method thereof

Abstract

The invention discloses a suspension bridge tunnel type anchorage cable crane and a construction method thereof and relates to the technical field of bridge hoisting construction. The suspension bridge tunnel type anchorage cable crane includes an anchoring assembly and a hoisting assembly, and the anchoring assembly comprises a gantry disposed at an opening and a rock anchor disposed on the rearrock surface in a hole. The hoisting assembly includes a bearing cable erected between the rock anchor and the top end of the gantry, a traction pulley and a traction cable for pulling the traction pulley are suspended below the bearing cable, and the lower end of the traction pulley is provided with a hook for hoisting a heavy object. The gantry includes a gantry cross beam and two gantry columns, the gantry cross beam is transversely disposed at the top of the two gantry columns, the gantry cross beam is provided with a lifting lug, and the lifting lug is connected with one end of the bearing cable. According to the suspension bridge tunnel type anchorage cable crane, the problem that the hoisting heights of a positioning bracket and a tunnel anchor steel pull rod are limited under the conditions that the height in a hole is limited can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of bridge hoisting construction, in particular to a suspension bridge tunnel type anchorage cable crane and a construction method thereof. Background technique [0002] The construction contents of tunnel type anchorage of suspension bridge mainly include: primary support, installation of anchorage system, reinforced concrete construction of anchor plug body and secondary lining construction. Except for the installation of the anchoring system, the rest of the processes are required to be carried out in an orderly manner in the tunnel anchor. However, for suspension bridges whose main cable anchorage system is designed as high-strength prestressed steel tie rods and positioning brackets are designed as trusses, it is basically impossible to hoist the positioning brackets in pieces and the overall hoisting of steel tie rods in the tunnel anchor according to the traditional method. There are relatively few ap...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the defects existing in the prior art, the purpose of the present invention is to provide a suspension bridge tunnel type anchorage cable crane, which can effectively solve the problem of the limited hoisting height of the positioning bracket and the tunnel anchor steel tie rod in the case of limited height in the cave.
