Description
Technical field
The present invention relates to a kind of building engineering equipment, particularly about surface of construction catwalk of suspension bridge set up, remove anti-hanging mobile trolley used.
Background technology
Along with advancing by leaps and bounds of infrastructures such as highway in China traffic,, progressively become one of first-selected bridge type of striding river, passage over strait as the strongest suspension bridge of span ability.The cat road is construct most important overhead work passage and one-shot job place of suspension bridge superstructure.The work high above the ground that cat road surface layer sets up, removes is very loaded down with trivial details and dangerous.Cat road surface layer is removed common way: personnel stand on the cat road surface layer, and veil is cut an opening, and hand and instrument are reached below the surface layer, turn on the U-bolt that is connected of cat road surface layer and cat road track cable.Cao Zuo shortcoming has like this: (1) complicated operation, inefficiency; (2) veil need be cut off, veil has suffered destruction, and recyclable utilization rate is low, has increased the waste of material; (3) bolt of turning on is easy to fall from the high-altitude, has increased below, cat road passing ships, personnel's potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple to operate, high efficiency, potential safety hazard is little and the surface of construction catwalk of suspension bridge of economical with materials sets up, removes mobile trolley used.
In order to solve the problems of the technologies described above, surface of construction catwalk of suspension bridge of the present invention sets up, removes mobile trolley used locking device, rolling pulley, tractive otic placode, anti-hanging bracket and the operating platform of mainly comprising.One end of described each anti-hanging bracket vertical fixing respectively is installed in the operating platform rear and front end, and the other end of anti-hanging bracket is being fixed rolling pulley respectively, hangs on the cat road track cable working platform is counter by rolling pulley and anti-hanging bracket.Tractive otic placode and rolling pulley are fixedly mounted on the upper end of the anti-hanging bracket of working platform one end jointly.Locking device and rolling pulley are fixedly mounted on the upper end of the anti-hanging bracket of the working platform other end jointly.
Surface of construction catwalk of suspension bridge of the present invention sets up, removes and mobile trolley usedly carries out work by following mode: when the constructor carries out setting up or removing operation and tightening or loosening U bolt of cat road surface layer, at first surface of construction catwalk of suspension bridge of the present invention is set up, removes the mobile trolley used anti-position that needs operation on the cat road track cable that hangs over, screw locking device, surface of construction catwalk of suspension bridge is set up, removes mobile trolley used fixing, and the constructor can carry out operation on working platform then.When carrying out the work of next work plane, loosen locking device earlier, carrying out tractive by the tractive otic placode again makes whole chassis move freely on cat road track cable by rolling pulley, screw locking device behind the arrival job position chassis is fixed, the constructor can continue operation on working platform then.
Adopt surface of construction catwalk of suspension bridge of the present invention to set up, remove mobile trolley used structure, easy and simple to handle, high efficiency and economical with materials.
As a kind of preferred structure of the present invention, can on working platform, lay veil.Adopt this structure, can the convenient construction personnel stand and prevent falling object from high altitude, strengthened security protection, reduced potential safety hazard.
As the further improvement of above-mentioned preferred structure, side that can working platform is with the side net.Adopt this structure, the side function of safety protection in the time of can playing constructor's work high above the ground.
The beneficial effect that the present invention reaches is, surface of construction catwalk of suspension bridge of the present invention sets up, removes mobile trolley used not only simple to operate, high efficiency, potential safety hazard is little but also economical with materials.
