Description

Technical Field

[0001] The present invention relates to a bridge maintenance equipment, and more particularly to a foldable maintenance vehicle for traveling along the bridge pier. Background Art

[0002] Bridge maintenance vehicles are indispensable auxiliary facilities for daily maintenance, inspection and repair of bridges, and also provide an operating platform for the bridge inspection process, equipped with bridge inspection and maintenance instruments. Existing bridge maintenance vehicles are mostly simple and motorized; simple bridge maintenance vehicles can only be moved manually, which is inconvenient to use; motorized bridge maintenance vehicles need to be carried on motor vehicles, wasting resources. Summary of the Invention

[0003] The present invention provides a foldable maintenance vehicle for traveling along the bridge pier, which has its own power and can travel along the bridge pier to safely and reliably complete bridge inspection, maintenance and repair work.

[0004] The technical solution of the present invention is as follows:

[0005] A foldable maintenance vehicle for traveling along the bridge pier includes a folding vehicle body, a driving wheel, a driven wheel, two supporting wheels, a traveling motor and a speed reducer. The driving wheel and the driven wheel are respectively arranged at both upper ends of the folding vehicle body, and the two supporting wheels are respectively arranged at both lower ends of the folding vehicle body. The driving wheel and the driven wheel are placed in the load-bearing track of the bridge pier, and the supporting wheels are placed on the supporting track of the bridge pier. The traveling motor and the speed reducer are installed on the folding vehicle body, and the traveling motor drives the driving wheel through the speed reducer to achieve traveling.

[0006] The preferred embodiment of the foldable maintenance vehicle for traveling along the bridge pier is that the folding vehicle body includes a side frame, a connecting rod, a support buckle and a support plate. The side frame is formed into a square structure by fixedly connecting a top side, a side edge and a bottom side. A cross beam is arranged between the two side edges. The support buckle is a channel steel structure, and both sides of the support buckle are rotatably connected to one end of the two connecting rods through pin shafts respectively, and the opening of the support buckle faces downward. The other end of the connecting rod is rotatably connected to the side edge and the bottom side of the two side frames through pin shafts respectively to form a foldable structure. The support plate is fixedly arranged on the side frame, and the traveling motor, the speed reducer and the driving wheel are arranged on the support plate.

[0007] The preferred embodiment of the foldable maintenance vehicle for traveling along the bridge pier is that the traveling motor is powered by a storage battery, and the storage battery is placed on the support plate.

[0008] The preferred embodiment of the foldable maintenance vehicle for traveling along the bridge pier is that the folding vehicle body is made of aluminum alloy material.

[0009] The working process of the foldable inspection vehicle used for traveling along the bridge pier is as follows: The load-bearing track and the supporting track on the bridge pier include a straight section and a curved section, and the radius of the curved section is about 1.8 meters; the storage battery provides power for the traveling motor, and the traveling motor drives the driving wheel to travel through a speed reducer. The driven wheel and the two supporting wheels rotate accordingly, realizing the movement of the folding vehicle body along the straight section of the load-bearing track and the supporting track; when passing through the curved section of the load-bearing track and the supporting track, first, pull up the support buckle, and the support buckle drives the two connecting rods connected to it to rotate. The two connecting rods are in a combined state, making the folding vehicle body in a folded state; then, the traveling motor drives the driving wheel to travel through a speed reducer, and the driven wheel and the two supporting wheels rotate accordingly, realizing the movement of the folding vehicle body along the curved section of the load-bearing track and the supporting track; on the straight section of the load-bearing track and the supporting track, press down the support buckle, and the support buckle drives the two connecting rods connected to it to rotate. The two connecting rods are in an open state, making the folding vehicle body in an open state, so as to store and transport the equipment used for daily maintenance, inspection and repair.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. The folding vehicle body is a foldable structure. When passing through the straight section of the track, the inspection vehicle is in an open or folded state. When passing through the curved section of the track, the inspection vehicle is in a folded state, and it can smoothly pass through the track curved section with a radius of 1.8 meters, ensuring that the folding vehicle body can continuously run around the bridge pier for one week.

[0012] 2. The folding vehicle body is made of aluminum alloy material, which improves the strength of the inspection vehicle body and is safe, light and not easy to rust.

[0013] 3. The storage battery is adopted to provide the running power source, which provides the traveling power for the inspection vehicle and can also be used as the power source for electric tools.

[0014] 4. The inspection vehicle is installed on the bridge pier, and the road does not need to be closed during the inspection operation, ensuring the smooth passage of vehicles on the bridge deck.

[0015] 5. The specific advantages of the present invention are: light, flexible and safe. Description of the Drawings
