[0015] The embodiments of the present utility model will be described in detail below with reference to the drawings. These embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific working processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.

[0016] As Figures 1-4 shown, the multifunctional unobstructed mobile bridge inspection vehicle of the present utility model includes an inspection vehicle body 1, an auxiliary vehicle body 3 connected to the inspection vehicle body 1 through a flipping bracket 2, a robotic arm is arranged on the auxiliary vehicle body 3, a detection camera 4 and a grouting repair gun 5 are arranged at the end of the robotic arm, and an unobstructed mobile reinforcement member 6 is further arranged between the robotic arm and the bottom surface of the bridge M.

[0017] Specifically, the detection vehicle body 1 is relatively small in volume. The first traveling wheels 11 are provided at the bottom thereof, and it travels along the edge of the road surface of the bridge M without occupying the normal traffic lane and without affecting normal traffic. The flipping bracket 2 is located at the top of the detection vehicle body 1 and close to one side of the guardrail of the bridge M. It includes a support 21 provided on the detection vehicle body 1 and a first connecting rod 22 provided on the side of the auxiliary vehicle body 3. The top of the first connecting rod 22 is hinged to the second connecting rod 23. A sliding block is provided at the bottom of the first connecting rod 22. The rod body of the second connecting rod 22 is fixedly connected to the support 21. The end of the second connecting rod 23 is hinged to the hydraulic arm 24, and the other end of the hydraulic arm 24 is hinged to the sliding block. The second traveling wheels 31 are provided at the bottom of the auxiliary vehicle body 3. In the non-detection state, the detection vehicle body 1 and the auxiliary vehicle body 3 travel side by side on the bridge surface, which is beneficial to maintaining the stability of the vehicle body. When detection is required, the length of the hydraulic arm 24 is adjusted to lift the auxiliary vehicle body 3 and flip it towards the guardrail of the bridge M. At this time, the second traveling wheels 31 are suspended.

[0018] A robotic arm is provided at the top of the auxiliary vehicle body 3. The robotic arm includes a multi-section first folding arm 71 hinged to the auxiliary vehicle body. The end of the first folding arm 71 is hinged to a multi-section telescopic arm 72. The end of the telescopic arm 72 is hinged to a second folding arm 73. A detection camera 4 and a grouting repair gun 5 connected by a universal joint are provided at the end of the second folding arm 73. In this embodiment, the first folding arm 71 has a two-section structure and is provided on the side of the bridge M. The telescopic arm 72 has a three-section structure, and both it and the second folding arm 73 are provided at the bottom of the bridge M. Between the above-mentioned first folding arm 71 and the auxiliary vehicle body 3, between adjacent segments of the first folding arm 71, between the first folding arm 71 and the telescopic arm 72, and between the telescopic arm 72 and the second folding arm 73, they are all connected by joint locks.

[0019] When the robotic arm is in the folded and retracted state, it is located on the side of the bridge M and is connected to the auxiliary vehicle body 3 through a first fixing buckle 81. When the robotic arm is in the unfolded state, in addition to being fastened by the first fixing buckle 81, a hydraulic support arm 82 hinged to both the first folding arm 71 and the telescopic arm 73 is also provided between the first folding arm 71 and the telescopic arm 73.

[0020] Since the bridge M is relatively wide and the horizontal section of the robotic arm is relatively long, in order to obtain good stability and ensure the shooting effect, a non-blocking movable reinforcement 6 is also provided between the robotic arm and the beam bottom.

[0021] The unobstructed mobile reinforcement member 6 includes a guide shaft 61 provided on the telescopic arm 72. The guide shaft 61 is driven by a micro-motor to rotate. The top of the guide shaft 61 passes through a linear guide groove 63 of the steering wheel plate 62. The linear guide groove 63 is perpendicular to the telescopic arm 72 (i.e., arranged along the traveling direction of the inspection vehicle body 1), and suction cup brackets 64 are provided at both ends of the linear guide groove 63. A telescopic locking pin is provided between the suction cup bracket 64 and the guide shaft 61. When the locking pin extends, the suction cup bracket 64 and the guide shaft 61 can be locked together to keep them relatively stationary; when the locking pin retracts, the suction cup bracket 64 is separated from the guide shaft 61 and they can move separately. A negative pressure suction cup 65 rotatably connected thereto is provided at the top of each of the above-mentioned suction cup brackets 64. When the two negative pressure suction cups 65 alternately adsorb to the bottom of the beam, certain support can be provided for the telescopic arm 72 and the second folding arm 73 without affecting the traveling of the inspection vehicle body 1.

[0022] The working process of the unobstructed mobile reinforcement member 6 is described in detail below. For the convenience of narration, the negative pressure suction cup 65 located on the front side of the traveling direction of the inspection vehicle body 1 is called the "front suction cup", and the other is the "rear suction cup". Since the traveling speed of the telescopic arm 72 is basically the same as that of the inspection vehicle body 1, therefore, the "traveling of the telescopic arm 72" is used instead of the "traveling of the inspection vehicle body 1".

[0023] When the telescopic arm 72 starts to travel, the front suction cup adsorbs to the bottom of the beam, the rear suction cup does not adsorb to the bottom of the beam, the guide shaft 61 is located at the rear end of the linear guide groove 63, and the guide shaft 61 and the rear suction cup bracket 64 are in an unlocked state; when the inspection vehicle body 1 starts, the telescopic arm 72 moves forward accordingly, and the guide shaft 61 moves forward along the linear guide groove 63 until it reaches the front end of the linear guide groove 63; at this time, the inspection vehicle body 1 pauses moving, the locking pin extends to lock the front suction cup bracket 64 and the guide shaft 61 together. After that, the micro-motor starts, the guide shaft 61 rotates, the steering wheel plate 62 rotates 180°, the linear guide groove 63 rotates accordingly, so that the guide shaft 61 is located at the rear end of the linear guide groove 63 again, and the original "front suction cup" and the original "rear suction cup" swap positions with each other, that is, the original "front suction cup" is located behind the original "rear suction cup". At this time, the original "rear suction cup" currently in the front is made to adsorb to the bottom of the beam, and the adsorption relationship between the original "front suction cup" currently in the rear and the bottom of the beam is released, that is, it returns to the initial traveling state; at this time, according to the above steps, a new round of "traveling of the inspection vehicle body 1" is carried out. During this process, due to the action of the unobstructed mobile reinforcement member 6, the wind vibration of the robotic arm is small, the stability is good, and a good shooting effect can be maintained.

[0024] Furthermore, in order to facilitate the movement of the negative pressure suction cup 65, the negative pressure suction cup 65 adopted in the present utility model includes a suction cup body. An annular wheel seat 652 is provided inside the annular sealing strip 651 of the suction cup body, and a plurality of universal wheels 653 are installed on the annular wheel seat 652.

[0025] In the present utility model, the detection camera 4 can comprehensively photograph the bridge and synchronously upload pictures during the photographing process. Diseases such as cracks are identified and rated through automatic image recognition technology in the cloud. When the crack level is relatively low, it is marked as a repairable crack. The robotic arm adjusts the angle of the grouting repair gun 5 under the instruction of the numerical control drive group to aim at and approach one side of the crack, and the internal crack repair material is extruded onto the crack. When the crack is on the side and concave surface of the small box girder, the grouting repair gun 5 can penetrate to ensure that photographing and repair operations can be carried out for all angles of the small box girder without dead angles for photographing and repair.

[0026] It should be noted that in the description of the present utility model, terms indicating orientation or positional relationships such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
