The specific embodiment
Below in conjunction with accompanying drawing, by instantiation, the utility model is described in further detail.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of highway special bridge bridge below apparatus for work, its innovation is: by the first work car 1, the second work car 15, construction mechanism, insurance institution, operation lower platform and People's Bank of China's cat ladder 5 form, the first work car comprises car body, mounting rail 2, supporting leg 4 and wheel 12, described supporting leg is arranged on four angles of car body below, the second described work car comprises car body, shelf, supporting leg and wheel form, between the first work car and the second work car, be provided with the construction mechanism that is positioned at bridge floor bottom, bottom at the top of construction mechanism bridge floor is provided with insurance institution, described operation lower platform is separately positioned on the bottom of the first work car and the second work car, on operation lower platform, be provided with People's Bank of China's cat ladder.
Construction mechanism consists of the Worker carrying basket 17 of Chain block 14, cable wire slideway 13, assembly pulley 18 and the cage structure of being welded by reinforcing bar, on the mounting rail of the first work car, be arranged with Chain block in parallel, on two Chain blocks, be connected with respectively one end of cable wire slideway, the other end at two cable wire slideways is fixed on the second work car, the middle part of each cable wire slideway is arranged on assembly pulley, and described Worker carrying basket is lifted on cable wire slideway by the hook on its four jiaos.
Insurance institution consists of chemical anchor bolts 11, cable wire 10 and safety rope (not shown), and cable wire is installed in the top of construction mechanism Worker carrying basket on bridge bottom surface by chemical anchor bolts, be provided with safety rope on cable wire.
In the second work car, be provided with balancing weight 16, the optional cement block of using of this balancing weight.
The car body of the first work car and the second work car is welded by steel, and its wheel is solid rubber tire, and this solid rubber wheel has advantages of anti-pressure and abrasion-proof.
Working vehicle's lower platform consists of fixed part 7 and movable part 6, in the both sides of fixed part, be provided with by the movable part of the folding collapsible installation of part, this folding part can be selected pin or hinge etc., and all can carry out movable part the part of telescopic folding, and this folding design has met that site operation environment is changeable, the adjustable needs of the scope of operation.
Operating principle of the present utility model is:
In the job area that Worker carrying basket can be installed at steel platform by cable wire slideway, move freely, the first work car and the second work car fixing tightwire slideway by the bridge floor left and right sides, under special construction environment, effectively carry out the scope of operation, improve operating efficiency, by insurance institution, provide construction operation personnel effective second protection measure simultaneously; Operation lower platform is made as the structure of detachability, when handling being installed when leaving office downwards from bridge floor position, because the restriction in space can be taken off the movable part of platform both sides, reaches the object of smooth assembling operation car.After arriving bridge below, can be according to the area that bases oneself upon of required increase platform, for construction operation is provided convenience.
During construction, by the supporting leg of the first work car on the guardrail 3 of up bridge 8 and downward bridge 9, Chain block is above the space between up bridge and downward bridge guardrail, weld job lower platform on the Liang Bi of bridge bearing beam below this space is provided with the People's Bank of China's cat ladder being connected on guardrail on operation lower platform; By the second work car be arranged on the outer side rail of bridge near, and place cement block on the shelf in car, prevent the movement of car, weld job lower platform on the Liang Bi of spandrel girder outside bridge is provided with the People's Bank of China's cat ladder being connected on guardrail on operation lower platform; Cable wire installation of slide track is below bridge floor, its one end is arranged on Chain block, the other end is arranged on the second work car by assembly pulley, by Chain block, realize forward and the counter motion of cable wire slideway on assembly pulley, two pass cable wire slideway guarantees operating steadily of Worker carrying basket, and the basket wall of hanging basket surrounding and safety rope have guaranteed constructor's safety.Constructor by under People's Bank of China's cat ladder to operation lower platform, and then from operation lower platform to Worker carrying basket, simultaneously, with it safety rope on cable wire is bundled in, play the effect of double insurance, along with personnel on bridge realize the motion of cable wire slideway to the control of Chain block, thereby play the object of adjusting Worker carrying basket position, the constructor in Worker carrying basket just can need to construct in the position of regulation according to construction.The process that safety rope can avoid constructor to change from operation lower platform to Worker carrying basket, step on that sky or Worker carrying basket fall and the safety problem that causes.There is convenient construction, safe and reliable to operation, changed the form of construction work of traditional lifting, saved to greatest extent resource, reduced cost.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
