Description

Technical Field

[0001] The present invention relates to the technical field of bridge detection, and particularly relates to an auxiliary mechanism for bridge appearance detection. Background Art

[0002] During the process of bridge appearance detection, the detection of the bottom surface of the bridge is particularly important because its position is under the bridge. Therefore, the detection is difficult and usually carried out by a bridge inspection vehicle. During the detection, the steel rails on the inspection vehicle are fixed on the bridge surface to overcome the overturning moment when lowering the workbench. The vehicle body can move along the steel rails within a certain length so that the workbench can detect a section of the area below the bridge surface. Since the detection is carried out within a certain range, multiple inspection vehicles need to work at multiple points to improve the efficiency, which consumes a large amount, and the bolt parts for positioning the steel rails will damage the surface of the bridge body; or the inspection vehicle is fixed at each point for detection, with low efficiency.

[0003] Based on the problems existing in the above-mentioned existing detection mechanisms, we propose an auxiliary mechanism for bridge appearance detection. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the background art, and to propose an auxiliary mechanism for bridge appearance detection.

[0005] To achieve the above object, the technical solution adopted by the present invention is: an auxiliary mechanism for bridge appearance detection, including two parallel vertical frames. A upper platform is arranged below the vertical frame, and a lower platform is fixedly connected below the upper platform. Steering mechanisms are respectively arranged inside the upper platform and the lower platform. The steering mechanism inside the upper platform drives the vertical frame to rotate, and the other steering mechanism drives the side seat to rotate. A telescopic mechanism is connected between the two side seats. A workbench is movably installed between the two side seats through an XY-axis moving mechanism. A suspension mechanism is arranged at the upper end of the vertical frame, and a clamping mechanism is arranged at the lower end of the vertical frame.

[0006] Preferably, the steering mechanism includes a rotating disc rotatably clamped inside the upper platform or the lower platform, a ring gear fixedly arranged on the upper surface of the rotating disc, a mounting seat fixedly installed on the upper surface of the upper platform or the lower platform, a first motor fixedly installed inside the mounting seat, and a driving gear fixedly connected to the output shaft of the first motor. The driving gear meshes with the ring gear. The side seat is fixedly sleeved on the edge of the lower rotating disc, and the lower end of the vertical frame is fixedly connected to the edge of the upper rotating disc.

[0007] Preferably, a connecting steel is fixedly connected between the upper platform and the lower platform.

[0008] Preferably, the telescopic mechanism includes a telescopic cylinder and a transverse cylinder arranged between the two side seats.

[0009] Preferably, the XY-axis moving mechanism includes toothed plates respectively and fixedly connected to the adjacent surfaces of the two side seats. The two toothed plates are staggered from each other. A slide rail is formed on the side surface of one toothed plate, and a slider protrudes from the side surface of the other toothed plate. The slider is slidably inserted into the inner side of the slide rail. A sleeve is slidably sleeved on the outer sides of the two toothed plates. A friction column is rotatably installed inside the sleeve. The friction column presses against the upper surface of the toothed plate. The central axis of the friction column is fixedly connected to the output shaft of a second motor, and the second motor is fixedly installed on the outer surface of the sleeve. The workbench is slidably matched with the upper surface of the sleeve.

[0010] Preferably, a guide seat protrudes from the lower surface of the workbench, and a guide rail is fixedly installed on the upper surface of the sleeve. The guide seat is slidably inserted into the inner side of the guide rail.

[0011] Preferably, a side toothed plate is fixedly arranged on the side surface of the guide seat, a third motor is fixedly installed on the outer surface of the sleeve, an output shaft of the third motor is fixedly connected with a driving gear, and the driving gear meshes with the side toothed plate.

[0012] Preferably, the clamping mechanism includes a connecting seat fixedly installed at the lower end of the vertical frame, a two-way cylinder fixedly clamped inside the connecting seat, and connecting plates respectively and fixedly connected to the two telescopic ends of the two-way cylinder. A clamping frame is fixedly installed on the side surface of the connecting plate.

[0013] Preferably, reinforcing rods are respectively and fixedly connected to the outer surfaces of the two sides of the connecting seat. The reinforcing rods slide through the connecting plate. A guide rod is fixedly connected to the side surface of one of the connecting plates, and the guide rod slides through the other connecting plate.

[0014] Preferably, the suspension mechanism includes a cross beam fixedly connected to the upper end of the vertical frame through an angle steel. The lower surface of the cross beam is fixedly connected to the telescopic end of a lifting cylinder, and a support is fixedly connected to the lower end of the lifting cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This solution is applied to a bridge body with equidistant beam-column distribution. By means of its beam-columns for positioning and overcoming the overturning moment, the coherence and efficiency during detection are ensured, and the surface of the bridge body is not damaged during positioning.

[0017] The auxiliary mechanism is arranged at the edge of the bridge body. The distance between the two vertical frames is controlled by the transverse cylinder, so that it is located on the side of the beam column. By controlling the contraction of the two-way cylinder, the clamping frames on both sides approach each other to fix the beam column. Workers go down from one side of the vertical frame and reach the workbench. By controlling the operation of the second motor, the friction column rotates. The toothed plate has a large friction force, so that the friction column rolls relatively on the surface, and then the workbench moves horizontally. Workers perform appearance inspection under the bridge body. When reaching the other side, the area can be relatively completely inspected. The arrangement and inspection are convenient, and there is no need to install and fix the track on the surface of the bridge body.

[0018] After the inspection of a certain area is completed, the workbench is moved to the middle position between the two vertical frames. At this time, the clamping frame on one side is loosened, and the first motor on the other side operates, so that the driving gear rotates, and the meshing ring gear rolls, and then the rotating disk below rotates, so that the vertical frame and other structures on the other side rotate until reaching the next beam column. Control the operation of the first motor on this side to make the upper rotating disk rotate 180 degrees to ensure that the clamping frame can clamp on the surface of the beam column again. At this time, the inspection under the bridge body of this area can be carried out again, and the consecutive inspection of each area can be carried out, effectively improving the inspection efficiency.

[0019] After the vertical frame rotates to the next beam column and is positioned, by controlling the operation of the third motor, the power gear rotates, and the position of the workbench can be adjusted to ensure that the inspection area under the bridge body can be fully adjusted.

[0038] As Figure 8 、 Figure 9 、 Figure 10 And Figure 11 shown, the XY-axis moving mechanism includes toothed plates 24 respectively fixedly connected to the closer sides of the two side seats 10. The two toothed plates 24 are distributed staggeredly. A slide rail 26 is arranged on the side surface of one toothed plate 24, and a slider 25 protrudes on the side surface of the other toothed plate 24. The slider 25 is slidably clamped inside the slide rail 26. A sleeve 27 is slidably sleeved on the outer sides of the two toothed plates 24. A friction column 28 is rotatably installed inside the sleeve 27. The friction column 28 presses against the upper surface of the toothed plate 24. The central axis of the friction column 28 is fixedly connected to the output shaft of the second motor 29, and the second motor 29 is fixedly installed on the outer surface of the sleeve 27. The workbench 30 is slidably matched with the upper surface of the sleeve 27. Specifically, a guide seat 35 protrudes from the lower surface of the workbench 30, and a guide rail 34 is fixedly installed on the upper surface of the sleeve 27.

[0041] Reinforcing rods 15 are respectively fixedly connected to the outer surfaces on both sides of the connecting seat 12, the reinforcing rods 15 slide through the connecting plate 14, a guide rod 16 is fixedly connected to the side surface of one of the connecting plates 14, the guide rod 16 slides through the other connecting plate 14, and the guide rod 16 improves the stability of the mutual movement of the two connecting plates 14.

[0043] As Figure 13As shown, during use, the auxiliary mechanism is arranged at the edge of the bridge body 36. The distance between the two vertical frames 1 is controlled by the transverse cylinder 22 to place it on the side of the beam column 37. By controlling the contraction of the bidirectional cylinder 13, the clamping frames 17 on both sides approach each other to fix the beam column 37. Workers go down from one side of the vertical frame 1 and, after reaching the workbench 30, control the second motor 29 to operate, thereby causing the friction column 28 to rotate. The toothed plate 24 has a large frictional force, causing the friction column 28 to roll relatively on the surface, and then causing the workbench 30 to translate. Workers conduct appearance inspections under the bridge body 36. When reaching the other side, the area can be relatively completely inspected. The arrangement and inspection are convenient, and there is no need to install and fix tracks on the surface of the bridge body 36. After the inspection of a certain area is completed, the workbench 30 is moved to the middle position between the two vertical frames 1. At this time, the clamping frame 17 on one side is loosened, and the first motor 8 on the other side operates, causing the driving gear 7 to rotate, causing the meshing ring gear 6 to roll, and then causing the rotating disk 5 below to rotate, causing the vertical frame 1 and other structures on the other side to rotate until reaching the next beam column 37. Control the first motor 8 on this side to operate, causing the upper rotating disk 5 to rotate 180 degrees to ensure that the clamping frame 17 can clamp on the surface of the beam column 37 again. At this time, the inspection under the bridge body 36 in this area can be carried out again, and consecutive inspections of each area can be carried out, effectively improving the inspection efficiency. After the vertical frame 1 rotates to the next beam column 37 and is positioned, by controlling the third motor 33 to operate, the power gear 32 rotates, and the position of the workbench 30 can be adjusted to ensure that the inspection area under the bridge body 36 can be fully adjusted.
