Description
Technical field
The utility model relates to bridge, particularly a kind of arch bridge inspection trolley anti-sway device.
Background technology
Along with the construction of high-speed railway and the expansion of the western mountainous areas railway network, the line is busy that road ratio is more and more higher for railroad bridge, crosses over high mountains and deep gullies, the long-span arch bridge on iceberg, plateau also gets more and more.Because these Arch Bridge Ribs sizes are large, the vertical discrepancy in elevation large (55 ~ 100m), the gradient is steep, and variable cross-section, field condition is very complicated, and the maintenance and inspection task of arch ring is more and more heavier, is also more and more difficult to carry out, makes troubles to bridge maintenance.
At present, the mode that large-span arch bridge adopts people to climb carries out Inspection and maintenance, abnormally dangerous, inefficiency, and some check point also cannot arrive.The little span Deck Arch Bridges of common road can adopt bridge floor inspection trolley Inspection, but large span Deck Arch Bridges is because arch ring dimensional structure is large, the gradient steep, variable cross-section on railway, high-mountain gorge areas field condition is very complicated, and common bridge floor inspection trolley checks less than arch ring and bottom surface thereof at all.
In Arch Bridge Ribs inspection, major part adopts instrument to detect at a distance, utilizes the means such as ultrasonic rebound to collect arch bridge data.So remote detection, can not do Direct Analysis to arch bridge disease, lacks field observation, more can not do corresponding process to disease.
Abroad, arch bridge testing fixture mainly adopts common bridge floor inspection trolley, namely special-purpose automobile chassis is equipped with jib or truss, by the flexible and rotation of jib or truss, detection operation is carried out at each position that bridge machinery personnel and equipment deliver to bridge arch.This kind of test mode not only expends height, and degree of safety is low, examination scope limited (encircle the vertical discrepancy in elevation large, field condition is complicated, checks less than full arch), and needs blocked road during Inspection, affects train passage, is not suitable for the inspection of railway arch bridge.Or adopt people to climb mode, this kind of test mode safety is low, and efficiency is low, and working strength is large, check point critical constraints, maintenance difficulty.
At home, the inspection of general arch bridge mainly contains following several mode:
1, common bridge floor inspection trolley.Discuss above, be not suitable for the inspection of railway arch bridge and large span arch ring can not be checked comprehensively.
2, people climbs inspection channel mode.Inspection personnel walks in inspection passage, and safety is low, and checking efficiency is low, and maintenance period is long, check point critical constraints.
3, track travel inspection trolley.This kind of test mode finds application at lower bearing arch bridge, but relevant art is perfect not enough.And in Deck Arch Bridges inspection, also do not have ripe scheme and practical application.
4, proping mode.This kind of test mode builds place limited (complex area such as high mountain gorge can not be built), takes time and effort, inefficiency, and affects traffic, need close traffic passage.
Therefore, arch ring arranges moveable testing fixture owing to checking whole arch ring, and structure being reliable, security performance is high, is the trend that railway arch bridge checks.But existing inspection trolley anti-sway device is all arrange two hydraulic dampers at homonymy, require long three times of being at least range and shortest route difference of the cylinder of hydraulic damper cylinder body.Operating mode for this kind short locating distance, Long Distances just must increase auxiliary body so that mounting arrangement cylinder body.Thus one, whole anti-wabbler mechanism is just very too fat to move, and oil cylinder is also deteriorated because of long whole damping capacity and stability, and cylinder bar slenderness ratio is too small simultaneously, and processing technology is more difficult, and cost increases.For large arch ring bridge inspection vehicle wide-angle beat, existing anti-sway device implements also very difficult.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of arch bridge inspection trolley anti-sway device, effectively to simplify the structure of anti-sway device and inspection trolley, makes the more compact and lightweight of the overall structure of inspection trolley.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
A kind of arch bridge inspection trolley anti-sway device of the present utility model, comprise and be arranged at inspection trolley car body, drive the first hydraulic damper between vehicle frame, second hydraulic damper, inspection trolley car body is hung on by suspension rod and drives on vehicle frame, it is characterized in that: described first hydraulic damper, second hydraulic damper is being arranged in X-shaped perpendicular to driving in the plane of top of frame, first hydraulic damper, the cylinder bar upper end of the second hydraulic damper is hinged with driving vehicle frame, hinged on the right side of the cylinder body lower end of the first hydraulic damper and inspection trolley car body, hinged on the left of the cylinder body lower end of the second hydraulic damper and inspection trolley car body.
The beneficial effects of the utility model are, first hydraulic damper, the second hydraulic damper adopt diagonal angle alternating expression layout, can effectively reduce cylinder long, corresponding auxiliary body can be removed, effectively can simplify the structure of anti-sway device and inspection trolley, make the more compact and lightweight of the overall structure of inspection trolley; Can reduce cylinder damping, increase Stability Analysis of Structures performance, reduced cost, can be easier to realize large arch ring inspection trolley wide-angle beat.
Accompanying drawing explanation
This manual comprises as next width accompanying drawing:
Fig. 1 is the structural representation of a kind of arch bridge inspection trolley of the utility model anti-sway device;
Component shown in figure and corresponding mark: inspection trolley car body 10, driving vehicle frame 11, arch ring 12, suspension rod 13, first hydraulic damper 21, second hydraulic damper 22.
