Bridge detects working vehicle, is a kind of disease maintenance of large and medium-sized bridge and special-purpose vehicle of preventive inspection operation of being applicable to.Major function is for comprehensively to check, to repair each structure of bridge, for bridge security provides safeguard.The maintenance content comprises member whether torsional deformation, local damage; Rivet and bolt have non-loosening, come off and rupture, and whether node slides, mistake is split; Weld edge has flawless or disengagement; Skin of paint has flawless, peeling, comes off, and member has non-corroding etc.Bridge detects working vehicle can be divided into suspension type traveling inspection trolley under bridge floor traveling inspection trolley and the bridge.Though it is more convenient that bridge floor traveling inspection trolley uses, but because set in brickwork mode detects bridge on road surface (on the rail) traveling or the ship, certainly will the road pavement traffic, the current hole or the navigation hole of bridge carry out the traffic sealing, bigger to traffic impact, security performance also has certain limitation simultaneously.
The utility model content
The purpose of this utility model has provided a kind of the needs and has avoided influencing road traffic by bridge floor, controls simultaneously conveniently, the inspection trolley that winds up that is used for steel purlin bridge of safety.
The technical solution of the utility model is as follows:
A kind of inspection trolley that winds up that is used for steel purlin bridge, this inspection trolley comprises walking track, horizontal truss, drive unit and vertical truss, described horizontal truss upper berth is provided with working platform, described horizontal truss places on the described walking track by the road wheel that the mobile roof support lower end is provided with, described drive unit clutch end is connected with the road wheel of described mobile roof support, described vertical truss is connected the both sides of described horizontal truss, vertically truss is provided with lift drive mechanism and elevator cage, and this elevator cage is connected the clutch end of described lift drive mechanism.
Adopt said structure walking track laying on the horizontal truss of steel purlin bridge, do not need through Crossing the bridge noodles, drive unit drives the horizontal truss lengthwise movement along steel purlin bridge of horizontal truss and vertical truss integral, elevator cage is vertically moving up and down in the truss under the driving of lifting actuating unit, and the staff can move overhauling and safeguard in positions such as steel bridge panel point at working platform or elevator cage.Having overcome former detection mode need be by the shortcoming of bridge floor, and this detection mode is safe, easy to operate simultaneously, examination scope is big.
This inspection trolley also comprises the top dolly, and this top dolly moves along the trolley track of laying on the described working platform, is hung with Lifting basket on the dolly of described top, and this Lifting basket drives by the electric block that is provided with on the dolly of described top.
The top dolly is laterally promoting to realize walking by manpower on the trolley track; Laterally the dolly below is provided with Lifting basket, and Lifting basket laterally moves with the top dolly, and realizes lifting by electric block.The inspection personnel just may stand in the inspection that realizes in the Lifting basket the steel purlin body of a bridge.
Described drive unit comprises motor, reductor and power transmission shaft, and described motor via reducer links to each other with described power transmission shaft input, and the output of described power transmission shaft is connected with the road wheel of described mobile roof support.
Described elevator cage side is connected with movable rail.
When checking beam body inner side, turn 90 degrees by movable rail is revolved, thereby platform is widened in the work when movable rail is checked as the beam body is inboard.
Beneficial effect: the utility model has changed the detection mode of conventional steel purlin bridge, has avoided in the testing process the influence of bridge deck traffic, and easy to operate, safety detects the path and almost can cover whole beam body.
