Description
Technical Field
The utility model belongs to the auxiliary device of bridge construction specifically is a laying device who relates to a single-tower suspension bridge catwalk.
Background
In the work progress of self-anchored suspension bridge, catwalk (the interim built on stilts road in the construction) is the temporary structure that uses in the suspension bridge construction, the main push-towing rope erects in the construction, the essential auxiliary device of transportation of personnel's walking and small-size material, this catwalk mainly comprises bearing cable, net piece and safety handle, the catwalk is aerial structure, under the normal conditions, the operation personnel stand on the bearing cable of catwalk, remove by the manpower, install the net piece, not only intensity of labour is big, and there is the potential safety hazard, the efficiency of construction has been reduced.
Disclosure of Invention
The utility model aims at providing a laying device of suspension bridge catwalk net piece, it is rational in infrastructure not only, convenient operation uses safe and reliable, can improve the efficiency of construction moreover, practices thrift construction cost.
The purpose of the utility model is realized like this: the utility model provides a laying device of suspension bridge catwalk net piece (be referred to net piece laying device for short), includes main tower, anchorage and bearing cable, main tower be located the middle part of bridge floor, have main cable saddle at the top of main tower, concrete placement's anchorage be located the left and right end portion of bridge floor respectively, bearing cable erect on main cable saddle (not drawn in the picture) at main tower top, the left end section of bearing cable fix on left anchorage, the right end section of bearing cable fix on the anchorage on right side, characterized by: the device for laying the suspension bridge catwalk mesh further comprises a winch, a fixed pulley block, a steel cable and the mesh, wherein the winch is fixedly arranged on an anchorage at the left side, the fixed pulley block is fixedly arranged on a main cable saddle at the top of a main tower, the left end section of the steel cable is fixedly connected with a winding drum on the winch, and the right end section of the steel cable penetrates through the fixed pulley block and then is connected with the mesh.
When the mesh laying device is used in construction, an operator only needs to connect each section of mesh on the bridge floor, the right end section of the steel cable is fixedly connected with the mesh, the mesh is supported on the bearing cable, then, the winch is started to upwards pull step by step, and the mesh is pulled from the bottom end of the catwalk and laid on the main cable saddle position on the main tower, so that the labor, material and financial resources are saved, the working efficiency is improved, and the potential safety hazard of mesh laying is reduced.
The utility model provides a laying device of suspension bridge catwalk net piece, it is rational in infrastructure not only, convenient operation uses safe and reliable, has improved the efficiency of construction moreover, has practiced thrift construction cost.
The laying device for the suspension bridge catwalk mesh sheet provided by the present invention will be further described with reference to the accompanying drawings and embodiments.
