Abstract
The utility model relates to a bridge maintenance device, in particular to a working vehicle for a main cable of a suspension bridge. The working vehicle for the main cable of the suspension bridge is used for maintenance of the main cable of the suspension bridge and comprises a vehicle frame, a plurality of walking wheels are distributed at intervals under the vehicle frame along the longitudinal direction, the vehicle frame can be placed on the main cable through the walking wheels and can move along the main cable, a hoisting device used for providing motive power for the movement of the vehicle frame is arranged on the front portion of the vehicle frame, a hanging basket connected to the vehicle frame in hinged mode is hung on the vehicle frame, each walking wheel is mounted on a lifting seat which can move up and down, and each lifting seat is driven to move up and down through a power device which is independently mounted on the vehicle frame. According to the working vehicle for the main cable of the suspension bridge, in the walking process of the working vehicle, the walking wheels are lifted in sequence to enable the vehicle frame to go cross appending obstacles on the main cable, construction difficulty is lowered, and maintenance efficiency is improved. In addition, side idler wheels and deviation rectification devices are arranged on two sides of the vehicle frame, the vehicle frame is not deflected in the walking and maintenance process, maintenance is convenient, and safety is improved.
Description
Technical field
The utility model relates to bridge maintenance equipment, specifically the main rope of suspension bridge work car that overhauls of a kind of main push-towing rope that is used for to suspension bridge.
Background technology
Suspension bridge is one of principal mode of large span bridge, with respect to other structural bridge, suspension bridge can be finished larger span with less material, bridge floor is relatively higher, the boats and ships trafficability characteristic is better, do not need to build interim bridge pier in the bridging process yet, can build at the water surface that The turbulent river crashes its way through, therefore become one of first-selected structure of modern bridge construction.
Main rope is the main supporting member of suspension bridge, generally make of high-tensile steel (steel wire, steel strand, wirerope etc.), at present bridge design application life all in 50 years to more than 100 years, even more than 150 years, the Corrosion Maintenance of steel member is most important, generally all more than hundred meters, the appurtenance service work difficulties such as main push-towing rope, hoist cable locker and main push-towing rope dehydrating unit are very large for the discrepancy in elevation of main push-towing rope from the bridge main tower to the bridge floor.At present, usually employing can be carried out the auxiliary repair operation along the work car that main push-towing rope is advanced, but existing main push-towing rope work car is subjected to structural limitations, is difficult to safety and keeps away the appurtenances such as cord clip on the main push-towing rope, intake and exhaust cover, Temperature Humidity Sensor, has increased the difficulty of maintenance; In addition, be difficult to rectify a deviation because External Force Acting causes the center of gravity deflection in the work car running with being, make troubles to operation, safety also is affected.
Summary of the invention
Technical problem to be solved in the utility model is, providing a kind of can advance and can stride across appurtenance on the main push-towing rope, the main rope of suspension bridge work car that upkeep operation efficient is high, easy to operate, safety is good at main push-towing rope.
Main rope of suspension bridge work car of the present utility model includes a vehicle frame, bottom of frame a plurality of road wheels that longitudinally have been intervally arranged, vehicle frame is located on the main push-towing rope by road wheel and can moves along the main push-towing rope walking, and the vehicle frame front portion arranges the winding plant that promising walking movement provides power; Also be hung with the hanging basket that is articulated and connected with vehicle frame on the vehicle frame; Each road wheel is installed on the liftable elevating bracket, and each elevating bracket drives lifting by power set that independently are installed on the vehicle frame.
Described vehicle frame both sides are respectively arranged with several side wheels, and the vehicle frame both sides are supported on the handrail wire rope of top, cable bridge main push-towing rope both sides by side wheel.
Deviation correcting device also is installed on the described vehicle frame, described deviation correcting device includes the pedestal that is installed on the vehicle frame, telescopic adjustment hydraulic cylinder is installed on the pedestal, it is hinged to adjust hydraulic cylinder rear end and pedestal, it is hinged with a swing arm to adjust the hydraulic cylinder front end, and the swing arm lower end is hinged on the vehicle frame and can it swings by the adjustment Driven by Hydraulic Cylinder; Be connected with a telescopic telescopic arm on the swing arm, be provided with the profiling piece that can engage with the handrail wire rope on the telescopic arm.
Described adjustment hydraulic cylinder and be provided with two groups by swing arm and the telescopic arm of adjusting Driven by Hydraulic Cylinder, the adjustment hydraulic cylinder in two groups stretch out direction respectively towards the both sides of vehicle frame, corresponding with the handrail wire rope of both sides respectively.
The utility model in the work car walking process, can pass through one by one lifting road wheel owing to adopt liftable road wheel, makes vehicle frame cross appurtenance obstacle on the main push-towing rope, has reduced difficulty of construction, has improved overhaul efficiency; In addition, can guarantee that by side wheel and the deviation correcting device that is arranged in the vehicle frame both sides vehicle frame walking and maintenance process keep not deflection, made things convenient for maintenance, have improved safety.
