[0032] The following further elaborates on this application Figure 1-6 in conjunction with the appended drawings.

[0033] An embodiment of this application discloses a bridge pier 7 detection device.

[0034] Referring to Figure 1 and Figure 2 , a bridge pier 7 detection device includes a traveling trolley 1, a camera 2, a conveying assembly 3, and a plurality of cylinders 4. The top of the bridge pier 7 has a capping beam 71, and the traveling trolley 1 is movably installed on the bottom wall of the capping beam 71. The traveling trolley 1 includes a mounting frame 11, a lifting member 12, a double-headed motor 13, and two rotating wheels 14. The two rotating wheels 14 are rotatably installed on the mounting frame 11, the double-headed motor 13 is installed on the mounting frame 11, and the two rotating wheels 14 are respectively installed on the output shafts at both ends of the double-headed motor 13; when the mounting frame 11 is erected above the capping beam 71, both rotating wheels 14 are in contact with the upper part of the capping beam 71. Starting the double-headed motor 13 can cause the rotating wheels 14 to rotate, so that the mounting frame 11 can move on the capping beam 71.

[0035] Referring to Figure 2 , there are two groups of lifting members 12, and the two groups of lifting members 12 are respectively installed on both sides of the mounting frame 11. The lifting member 12 includes a first motor, a winding wheel 121, and a steel wire rope 122.

Starting the first motor can cause the steel wire rope 122 to wind / unwind on the surface of the winding wheel 121, so that the cylinder 4 can move in the height direction of the bridge pier 7.

[0036] Referring to Figure 1 and Figure 3, the casing 4 includes two half-casings 41 which are connected by fixing members; before sleeving the casing 4 on the bridge pile 7, first connect the two half-casings 41 to the two wire ropes 122 respectively; then use the traveling trolley 1 to enable the two half-casings 41 to be connected to the wire ropes 122 at a wide position, and start the double-headed motor 13 to enable the two half-casings 41 to be located on opposite sides of the bridge pile 7 respectively; then start the first motor to enable the wire rope 122 to be released from the surface of the winding wheel 121, so that the casing 4 is lowered underwater.

[0037] Refer to Figure 3 , in this embodiment, the fixing member is made of a first bolt and a first nut. One of the half-casings 41 is provided with a first mounting hole 42, and the other half-casing 41 is provided with a second mounting hole 43; when the two half-casings 41 are spliced, the first mounting hole 42 and the second mounting hole 43 are arranged opposite to each other, the first bolt passes through the first mounting hole 42 and the second mounting hole 43, and the first nut is connected to the first bolt, so that the two half-casings 41 can be connected, and the structure of the first bolt is simple, which is convenient for the staff to connect the two half-casings 41.

[0038] Refer to Figure 1 , after all the casings 4 are sleeved on the bridge pile 7 in sequence, two adjacent casings 4 are connected by connecting members, and there is a gap between the inner wall of the casing 4 and the inner wall of the bridge pile 7 to form a photographing space 46. In this embodiment, the connecting member includes a second bolt and a second nut. One of the casings 4 is provided with a third mounting hole 44, and the other casing 4 is provided with a fourth mounting hole 45. The second bolt passes through the third mounting hole 44 and the fourth mounting hole 45, and the second nut is matched with the second bolt, that is, the two adjacent casings 4 are fixed.

[0039] Refer to Figure 4 , a plurality of racks 5 are arranged on the inner walls of the two half-casings 41, and the extending direction of the racks 5 is the same as the length direction of the bridge pile 7; when all the casings 4 are connected in sequence, the racks 5 of two adjacent casings 4 are arranged opposite to each other. There are multiple groups of cameras 2, and all the cameras 2 are respectively slidably mounted on the racks 5, and all the cameras 2 can detect the bridge pile 7 in all directions, improving the monitoring effect on the bridge pile 7.

[0040] Refer to Figure 5 , the conveying assembly 3 is used to drive the camera 2 to slide on each rack 5. The conveying assembly 3 includes a slider 31, a gear 32 and a driving member 33. The camera 2 is mounted on the slider 31, and the slider 31 is provided with a sliding groove 34 for the rack 5 to slide; a rotating groove 35 is formed in the inner wall of the sliding groove 34, and the rack 5 is rotatably mounted in the rotating groove 35, and the gear 32 is meshed with the rack 5. In this embodiment, the driving member 33 is set as a second motor, and the second motor is mounted on the slider 31 and the output shaft of the second motor is fixed to the gear 32.

[0041] Starting the driving member 33 can engage the gear 32 with the rack 5, causing the gear 32 to move on the rack 5, and further enabling the camera 2 to move on the rack 5. Moreover, the cooperation between the gear 32 and the rack 5 can achieve the precise movement and positioning of the camera 2, realizing the precise shooting of the bridge pile 7.

[0042] Referring to Figure 6 , a limiting wheel 6 is provided on the inner wall of the semi-cylinder 41. The limiting wheel 6 includes a fixed rod 61, a sleeve 62, a telescopic rod 63, a spring 64, and a movable wheel 65. The fixed rod 61 is welded to the inner wall of the semi-cylinder 41. The fixed rod 61 is provided with a first kidney-shaped groove 622, the sleeve 62 is provided with a connecting portion 621, and the connecting portion 621 is provided with a second kidney-shaped groove 66. A third bolt is commonly inserted through the first kidney-shaped groove 622 and the second kidney-shaped groove 66. The cooperation between the first kidney-shaped groove 622 and the second kidney-shaped groove 66 can change the length of the limiting wheel 6, enabling the limiting wheel 6 to abut against bridge piles 7 with different inner diameters, improving the practicability of the device.

[0043] The telescopic rod 63 is movably installed in the sleeve 62. The spring 64 is sleeved on the outer walls of the telescopic rod 63 and the sleeve 62. The two ends of the spring 64 are respectively connected to the ends of the telescopic rod 63 and the sleeve 62 that are far away from each other. The elastic force of the spring 64 is used to drive the telescopic rod 63 to move towards the side away from the sleeve 62. The movable cooperation between the telescopic rod 63 and the sleeve 62 can further change the length of the limiting wheel 6.

[0044] The movable wheel 65 is rotatably installed on the telescopic rod 63. When the two semi-cylinders 41 are sleeved on the outer wall of the bridge pile 7, the movable wheel 65 abuts against the outer wall of the bridge pile 7, which can keep a gap between the bridge pile 7 and the inner wall of the casing 4, reducing the collision between the side wall of the bridge pile 7 and the camera 2 and preventing damage to the camera 2. Moreover, when the movable wheel 65 abuts against the outer wall of the bridge pile 7, the spring 64 can absorb the impact of the contact between the movable wheel 65 and the bridge pile 7, reducing the possibility of damage to the movable wheel 65.

[0045] The implementation principle of a bridge pile 7 detection device in an embodiment of this application is as follows:

[0046] When using the camera 2 to monitor the state of the bridge, all the casings 4 are sleeved on the bridge pile 7, and adjacent casings 4 are connected using second bolts; this creates a shooting space 46 inside the casing 4. At this time, alum is added to the shooting space 46 to make the water inside the shooting space 46 clear. Then, the second motor is started to drive the gear 32 to rotate, enabling the camera 2 to be slidably installed on the inner walls of all the casings 4, facilitating the movement of the camera 2 along the length direction of the bridge pile 7 and shooting it, improving the monitoring effect of the bridge.

[0047] The above is the preferred embodiment of the present application. It does not limit the protection scope of the present application.
