Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection equipment, in particular to a guardrail-hanging intelligent bridge detection vehicle. Background Art

[0002] In order to ensure driving safety, it is necessary to regularly monitor diseases after the bridge is built. Among them, for the detection of bearings, capping beams and cracks on the outer side of the bridge, a truss-type detection vehicle is mostly used. This type of detection vehicle has a large volume and occupies one lane when traveling on the bridge deck, affecting traffic. Secondly, in order to pass smoothly, when encountering bridge cables, it is necessary to retract the truss hanging basket that is on the outer side of the bridge in the working state, and then put it down again after passing the bridge cables, which seriously affects the work efficiency. Thirdly, the detection personnel stand in the truss hanging basket, which has certain potential safety hazards. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a guardrail-hanging intelligent bridge detection vehicle, and the following specific technical solutions can be adopted:

[0004] The guardrail-hanging intelligent bridge detection vehicle of the utility model includes a main body moving frame, on which a traveling track is arranged on the side and a first traveling wheel is arranged at the bottom, and the traveling track corresponds to the bridge guardrail cross bar; an auxiliary moving frame is also arranged on the main body moving frame and is connected through a flipping bracket. The auxiliary moving frame is located on one side of the traveling track, and a second traveling wheel is arranged at its bottom and a detection camera is arranged at the top and is connected through a folding arm; wherein, the auxiliary moving frame has a first state in which the second traveling wheel is in contact with the bridge road surface and a second state in which the second traveling wheel is suspended outside the bridge guardrail.

[0005] A solar power supply component is arranged on the main body moving frame, and the solar power supply component is connected to the driving mechanisms of the first traveling wheel and the traveling track.

[0006] A counterweight block is arranged on the main body moving frame.

[0007] A pressing member that is in sliding contact with the bridge guardrail cross bar is arranged on the main body moving frame.

[0008] The flipping bracket includes a support arranged on the top of the main body moving frame and a first connecting rod arranged on the side of the auxiliary moving frame. The top of the first connecting rod is hinged to a second connecting rod, a sliding block is arranged at the bottom of the first connecting rod, the rod body of the second connecting rod is fixedly connected to the support, the end of the second connecting rod is hinged to a hydraulic arm, and the other end of the hydraulic arm is hinged to the sliding block.

[0016] The embodiments of the utility model will be described in detail below in conjunction with the drawings. These embodiments are implemented on the premise of the technical solution of the utility model, and detailed implementation manners and specific working processes are given. However, the protection scope of the utility model is not limited to the following embodiments.

[0017] As Figures 1-4 shown, the intelligent inspection vehicle for bridge with guardrail suspension described in the utility model is applicable to the operation of small box girders with a span within 30 meters, and includes a main mobile frame 1, a flipping bracket 2, an auxiliary mobile frame 3, a folding arm 4, a detection camera 5, etc.

[0018] Specifically, the main body moving frame 1 is small in size, with a flat and long bottom surface. Its top surface is higher than the bridge guardrail M, and it can move forward closely along the bridge guardrail M without occupying the normal driving lane of the bridge deck road N. The first walking wheels 11 are installed at the bottom of the main body moving frame 1, and the walking tracks 12 are installed on the side facing the bridge railing M. Among them, the walking tracks 12 are arranged corresponding to the crossbars of the bridge guardrail M, and at least two are arranged in parallel. During operation, the first walking wheels 11 are in contact with the bridge deck road N, and the walking tracks 12 are in contact with the crossbars of the bridge guardrail M, realizing dual-drive walking.

[0019] Both the above-mentioned first walking wheels 11 and the walking tracks 12 are powered by a solar power supply component 13 arranged on the main body moving frame 1. The solar power supply component 13 includes a solar panel 131 and a battery pack 132. Among them, the solar panel 131 is arranged on the top of the main body moving frame 1 and on the side opposite to the walking track 12, and the battery pack 132 is arranged below the top solar panel 131.

[0020] Since components such as the auxiliary moving frame 2 and the folding arm 3 are installed on one side of the main body moving frame 1, in order to prevent the main body moving frame 1 from tipping over, a counterweight 14 is installed at its bottom, and a pressing member 15 connected to a jack rod is installed on its side. The above-mentioned pressing member 15 is arranged on the same side as the walking track 12, is located under the side of the crossbar of the bridge guardrail M, and is installed with a rubber roller connected to the crossbar of the bridge guardrail M.

[0021] An auxiliary moving frame 3 connected through a flipping bracket 2 is also arranged on the main body moving frame 1. The auxiliary moving frame 3 is located on one side of the walking track 12. Its bottom is provided with second walking wheels 31, and its top is provided with a detection camera 5 connected through a folding arm 4.

[0022] The above-mentioned flipping bracket 2 includes a support 21 installed on the top of the main body moving frame 1 and a first connecting rod 22 installed on the side of the auxiliary moving frame 3. The top of the first connecting rod 22 is hinged to the second connecting rod 23, and a sliding block 24 is sleeved at the bottom of the first connecting rod 22. The rod body of the second connecting rod 23 is fixedly connected to the support 21, and the end of the second connecting rod 23 is hinged to the hydraulic arm 25. The other end of the hydraulic arm 25 is hinged to the sliding block 24. When the piston rod of the hydraulic arm 25 fully extends, the second traveling wheel 31 is located at the bottom of the auxiliary moving frame 3. When on the bridge deck road N, the auxiliary moving frame 3 and the main body moving frame 1 travel in parallel, that is, the auxiliary moving frame 3 is in the first state. Since the auxiliary moving frame 3 also touches the ground and travels, the pulling and pressing forces on the main body moving frame 1 by the folding arm 4, the detection device, etc. are reduced. When detection is required, the main body moving frame 1 approaches the bridge guardrail M. By contracting the piston rod of the hydraulic arm 25, the auxiliary moving frame 3 is flipped upward. Then, the piston rod of the hydraulic arm 25 extends, causing the auxiliary moving frame 3 to fall and be located outside the bridge guardrail M. At this time, the second traveling wheel 31 is suspended, and the auxiliary moving frame 3 is in the second state.

[0023] The above-mentioned folding arm 4 includes a longitudinal robotic arm 41 and a transverse robotic arm 42 made of carbon fiber. It is light in weight but good in stability, and can weaken the influence of wind vibration during long-radius operations. The longitudinal robotic arm 41 is hinged to the auxiliary moving frame 3, and the transverse robotic arm 42 is hinged to the end of the longitudinal robotic arm 41. A joint lock 43 is provided at the connection between the transverse robotic arm 42 and the longitudinal robotic arm 41. A detection camera 5 is installed at the end of the transverse robotic arm 42, and a repair device can also be installed when necessary. When long-term shooting, repair, etc. need to be carried out in a certain area, in order to prevent the transverse robotic arm 42 from sagging, a negative pressure suction cup 44 can be installed on it to adsorb it to the bottom of the box girder.
