A cantilever type girder lifting system with a tower attached to a mountainous area

Abstract

The invention discloses a cantilever type loop-handled truss hoisting system for a high-altitude attached tower in a mountainous area. The cantilever type loop-handled truss hoisting system for the high-altitude attached tower in the mountainous area comprises cantilever support seats, connecting seats, cushion blocks, a support plate, a guide rail, a supporting and walking mechanism, a truss hoisting bracket I, a walking and lifting mechanism I, a truss hoisting cross beam, pull ropes, a stand column I, a fixed clamping block I, a stand column II, a fixed clamping block II, a truss hoisting bracket II and a walking and lifting mechanism I. The cantilever type loop-handled truss hoisting system for the high-altitude attached tower in the mountainous area provided by the invention is reasonable and simple in structure, low in production cost and convenient to install; through arranging the walking and lifting mechanism I and the walking and lifting mechanism I, the requirements on lifting and hoisting truss components and hoisting during assembling are net, and the working efficiency is further improved. Through the arranged supporting and walking mechanism, the hoisting range can be improved, and especially the cantilever support seats, the connecting seats, the cushion blocks and the supports are hoisted so as to be conveniently installed on tower columns, so that the system can be expanded along with the working procedure, the hoisting assembling of the system can be carried out without the need for adopting a large-sized hoisting device, and a large number of cost and time is saved.

Description

technical field [0001] The invention relates to the field of bridge construction equipment, in particular to a cantilever-type beam-lifting and truss-hanging system with a tower attached to a high altitude in mountainous areas. Background technique [0002] my country has a vast area of ​​mountainous areas. With the rapid development of road traffic construction, more and more continuous steel truss bridges are being built in mountainous areas. However, the construction of large-scale bridge steel truss girders in mountainous areas has difficulties such as steep mountains, difficulties in building temporary structures, narrow bridge locations, large construction site restrictions due to terrain conditions, and large height differences between the steel truss bridge deck and the ground. The overall installation of steel truss girders The difficulty is very great. In areas with more complex landforms, such as V-shaped canyons, it is almost impossible to install steel trusses a...

Problems solved by technology

[0003] The object of the present invention is to provide a cantilever-type girder crane system with a tower attached to a mountainous area in order to solve the above problems, so as to solve the problem that due to the various sizes and weights of girder members, especially large-size and heavy-weight members, it is impossible to use conventional tower cranes. The problem of high-altitude lifting
