Abstract
The utility model relates to a lifting maintenance car, which comprises a maintenance car assembly, a driving mechanism, a lifting mechanism and a braking mechanism. The utility model is characterized in that the maintenance car also comprises the lifting mechanism, wherein the lifting mechanism comprises a U-shaped main truss and a movable truss; the U-shaped main truss is connected with the movable truss by a lifting system; the lifting system is fixed on a lifting platform of the U-shaped main truss and adopts four ring-chain type electric hoists as the lifting power plants; the upper and the lower parts of the U-shaped main truss are respectively provided with a corresponding lead limit switch; and the braking mechanism is the electrical control hydraulic brake. In the lifting maintenance car, with the adoption of the structural design of the combined truss, the main truss is designed into the U-shaped structure, the movable truss can goes up and down freely in the main truss by the lifting system, and the structure form is safe and reliable and has convenient operation and superior performance.
Description
Technical field
The utility model relates to a kind of lift maintaining car, is mainly used in the periodic inspection and the anti-corrosion repair of the superimposed steel box girder bridge of variable cross-section.
Background technology
In the bridge of steel work, bridge inspection car all adopts fixed truss at present.By electric drive system or directly drive fixedly that truss travels with manual drives, its braking then employing all be hand-operated brake.All adopting in the bridge of multi span structure and variable section structure increases tool car or interim erection construction platform, solves the position that fixed truss tool car can't arrive.Its defective with increase the cost input, it is attractive in appearance to influence integral bridge simultaneously.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can freely rise, descend, the comprehensive bridge inspection car that satisfies bridge maintenance.
For solving the problems of the technologies described above, the utility model comprises inspection trolley assembly, driving mechanism, elevating mechanism, arrestment mechanism, it is characterized in that, described tool car also comprises elevating mechanism, this elevating mechanism comprises U type main couple and a bascule, adopts jacking system to connect between bascule and the U type main couple.
In the such scheme, described jacking system is fixed on the lift platform of U type main couple, and it is lifting power plant that this jacking system adopts four loop chain type electric blocks.
In the such scheme, the upper and lower position of described U type main couple respectively is provided with corresponding lead limit switch.
In the such scheme, described arrestment mechanism is the electric control hydraulic braking device.
The utility model is owing to adopted combined truss structure design, main couple to be designed to U type structure, and bascule is by jacking system upper and lower free lifting in main couple, and its form of structure is safe and reliable, and is easy to operate, superior performance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is the structural representation of the utility model elevating mechanism.
The specific embodiment
As shown in the figure, in the middle of U type main couple 1 bascule 7 is arranged, bascule 7 is connected by fixed connecting piece 5 with U type main couple 1; Jacking system 3 is arranged on the jacking system workbench 2, and is connected with guide rail 4 by lifting connector 6.
It should be noted last that, the above specific embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
