Abstract
The utility model relates to a maintenance platform in a huge project, in particular to a mobile fixed point maintenance platform for a large dam road bridge, which comprises a hanger platform and guardrails arranged on the road bridge, wherein the two sides of the hanger platform are connected with a cross beam by a connecting rod; a chain block is arranged between the cross beam and the hanger platform; the cross beam is hinged with a pulling rod with a chain wheel on the upper end; the guardrail is provided with bearing tubes in parallel; one end of the bearing tube is connected with a weight tray, and the other end thereof is provided with a slideway which is matched with the chain wheel. Compared with the prior art, the utility model is simple in the structure, is convenient to manufacture, can be recycled, has high safety factor and convenient operation, can not effect the normal living and production, and is short in the repair time.
Description
Technical field
The utility model relates to maintenance platform in the major works, specifically a kind of dam road bridge fixed point maintenance mobile platform.
Background technology
Fixed point inspection, the service work of lower storage reservoir dam road bridge are heavy, present repair method is to use ship to build scaffold with steel pipe under road bridge between the water surface and bridge to carry out service work, because the steel pipe quantity that the every bridge of road bridge uses is many, volume, the weight of steel pipe are big, repair time is quite long, waste bigger man power and material, and in maintenance process, need the vehicle of road bridge to break off a friendship, have a strong impact on normal production and life.
The utility model content
The utility model technical issues that need to address are: provide a kind of simple in structure, and under the situation that road bridge is not broken off a friendship, the dam road bridge fixed point maintenance mobile platform that can overhaul road bridge at short notice.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of dam road bridge fixed point maintenance mobile platform, comprise suspension bracket platform and the guardrail that places on the road bridge, the both sides of described suspension bracket platform are connected with crossbeam with connecting rod, between crossbeam and the suspension bracket platform Chain block are housed; Be hinged with the pull bar of upper end band pulley on the described crossbeam; Be set side by side with bearing tube on the guardrail, an end of this bearing tube is connected with ballast box, on its other end slideway is housed, and this slideway and pulley are used.
Compared with prior art, the utility model is simple in structure, and is easy to make, can be recycled, and the safety factor height, easy to operate, do not influence normal life, production, the repair time is short.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing 1-2, in the present embodiment, use diameter as the weldering of the steel pipe of 50mm make a long 10m, wide 1m, high 1m is the suspension bracket platform 5 of cuboid frame construction, the bottom of this suspension bracket platform 5 is fixing with the bamboo raft tiling.All be connected with crossbeam 9 above the suspension bracket platform 5 in the both sides of suspension bracket platform 5, a Chain block 11 is housed respectively between crossbeam 9 and the suspension bracket platform 5 with connecting rod 10.What described crossbeam 9 adopted is that diameter is the steel pipe of 20mm, is hinged with two pull bars 12 on the crossbeam 9, and these pull bar 12 upper ends all are equipped with pulley 8.Being set side by side with diameter on the guardrail 2 is the bearing tube 3 of 50mm, and an end of this bearing tube 3 is connected with ballast box 4 on being fixed on road bridge 6, is welded with a grooved slideway 7 on its other end, and this slideway 7 is used with the pulley 8 of pull bar 12 upper ends.
Using method of the present utility model is: after suspension bracket platform 5 installs, the maintainer can be by walking back and forth in suspension bracket platform 5, diverse location to road bridge 6 carries out highly difficult operations such as drill hole sampling, charing, after a hole road bridge inspection finishes, remove the connecting rod 10 of platform upstream side, make suspension bracket platform 5 one ends sagging, unsettled, utilize the connecting rod 10 in downstream on slideway 8, to slide, realize that suspension bracket platform 5 integral body are moved to next hole road bridge, reconnect the connecting rod 10 of inspection platform upstream side then.So repeatedly, can finish the fixed point service work of road bridge at short notice.
