Description
Technical field
The present invention relates to bridge inspection field, particularly relate to a kind of bridge top chord check car.
Background technology
Bridge inspection vehicle is that one provides job platform for bridge inspection maintenance personal in bridge inspection and maintenance process, can equip bridge inspection equipment and maintenance facility, detects or maintain the special engineered vehicle of operation for flowing checking.It can shift position at any time, allows bridge inspection maintenance personal enter job position safe, fast, efficiently and carries out upkeep operation.Current bridge inspection vehicle become large bridge especially steel structure bridge carry out routine servicing and keep in repair indispensable equipment.
Steel truss girder was mostly flat beam string structure form in the past, the checkout facility that winds up adopts railing walking type, electric railway top chord check car adopts steel bridge anti-power repairing vehicle, driven by manpower, structure is simple, and cost is lower, be widely used, owing to not possessing climbing function, the parallel chords steel truss girder that the scale that is applicable to is less winds up inspection use, and total length arranges bilateral track out of shape.
Because longspan steel truss girder adopts curve form to get more and more, domestic current existing railway curve trussed bridge mostly is arch, top chord check car is bridge one design substantially, need inspection trolley to possess climbing capacity by the bridge of Nanjing being won completely to Guan Qiao, the new Gan Jiangqiao in east, aqueduct etc. of conquering east has curve truss, inspection trolley main is at present rubber-tyred inspection trolley, chain type inspection trolley and oil cylinder replace jacking walking inspection trolley etc.
Rubber-tyred inspection trolley uses solid tyre as heavy burden parts, act on the i iron or T shaped steel that are connected to and wind up, ensured the normal pressure of tire and track by the clamping device of acting in opposition, thus make tire and track produce enough frictional force to walk on the slope to make inspection trolley; Rubber-tyred inspection trolley simple structure, reliable in action, but provide frictional force owing to leaning on rubber tyre, the problem of aging of rubber tyre in outdoor will determine the life and reliability of inspection trolley, and the pollution of inspection trolley raceway surface also may affect the frictional force at interface.
Chain type inspection trolley is improved on the basis of rubber-tyred inspection trolley, i iron or T-shaped steel track embed a continuous print chain, inspection trolley directive wheel then there are the wheel of a gear-like and chain interact, drive this pinion rotation inspection trolley namely to move ahead, the engaging of gear and chain can ensure that inspection trolley is climbed and walk; Chain type inspection trolley climbing capacity is strong, and without ageing of rubber problem, more reliably, but chain type inspection trolley does not possess the ability of crossing pinnacle, and the chain track system that needs are more complicated, its expense and maintenance difficulties higher.
Hydraulic cylinder replaces jacking walking inspection trolley and is derived by frame mast crane, reliable in action, and track structure is simple, but the speed of travel is comparatively slow, and latch action is wayward, and hydraulic test is many, difficult in maintenance and complicated.
Some other inspection trolley body design all can not cross pinnacle for above-mentioned top chord check car and market, realized top by can pinnacle be changed into curve top after track transformation, but need extra support and connection and have considerable influence to bridge appearance; Another shortcoming of above-mentioned inspection trolley all needs to arrange dedicated track, comparatively waste for the large bridge that main bridge is larger, dedicated track also needs the tie point of One's name is legion to be fixed in agent structure, tie point is difficult to Inspection and maintenance as concealed work, easily breaks down and jeopardizes personal safety; And locking structure reliability is lower, climbing Reliability of Microprocessor is difficult to ensure.
Therefore, for above deficiency, need to provide a kind of bridge top chord check car.
Summary of the invention
The technical problem to be solved in the present invention be present stage bridge inspection vehicle cross pinnacle by track transformation, need extra support and connection and dedicated track, for the problem of comparatively wasting the large bridge that main bridge is larger.
In order to solve the problems of the technologies described above, the invention provides a kind of bridge top chord check car, comprise and connect corridor and column, described column is fixed on described connection corridor, two ends, described connection corridor are symmetrical is respectively provided with walking mechanism, described connection corridor is arranged on bridge movably by described walking mechanism, described walking mechanism comprises walking beam and carrying platform, described carrying platform is arranged on described walking beam movably, described walking beam is arranged on bridge movably, the bottom of described walking beam is provided with claw, the top of described carrying platform is fixed with the described corridor that is connected, liftable support clips is provided with bottom it, bridge is provided with multiple connector, described claw and described support clips can be connected on the connector on bridge.
Wherein, described walking beam is equipped with tooth bar, the bottom of described carrying platform is provided with the gear be meshed with described tooth bar, and described carrying platform is arranged on described walking beam movably respectively by described tooth bar and described gear.
Wherein, the bottom of described walking beam is also provided with directive wheel, and described walking beam is arranged on bridge movably by directive wheel.
Wherein, described connector is provided with loaded axle, and claw can be connected on described loaded axle.
Wherein, described support clips is liftably arranged on the bottom of described carrying platform by screw mandrel, and described support clips can be connected on described loaded axle.
Wherein, the internal sleeve of described column is connected to flexible truss, and described column matches by regulating flexible truss and bridge depth of beam.
Wherein, described column is provided with working platform.
Wherein, described column is provided with antiswing device, and described antiswing device is used for preventing described connection corridor and described column from swinging in advance process.
Wherein, described connection corridor mid-mounting has hanging basket.
Technique scheme tool of the present invention has the following advantages: bridge top chord check car provided by the present invention can be climbed without the need to laying track by the setting of walking mechanism, compare traditional inspection trolley, save the material laying track, utilize bridge construction installation connecting element, do not need boring, because connector quantity is few, simple structure, reaches same agent structure and uses with the life-span, solves the problem of inspection trolley track maintenance difficulty, simultaneously because quantity is few, the expense of rail portion does not increase and even can reduce; Because connector can be accomplished non-maintaining, then only need maintenance test car can ensure the normal operation of whole system, then the maintenance point of whole system is few, and the workload of maintenance and expense can reduce greatly; Full-bridge is with low cost only just can complete task of needing multiple devices simultaneously to work with a complete equipment, and detection range involves full-bridge, and dead angle is almost nil, overall appearance.Without the need to welding, the present invention is lightweight, and cost of transportation is low, and simple installation is applied widely.
