[0030] The spraying assembly 40 and the detection assembly 50 all include the mounting seat 41, the annular slide 11 for accommodating the mounting seat 41 is arranged above the sleeve ring 10, the first transmission assembly 60 for contacting the bridge pier is arranged in the inside of the rotating ring 20, the second transmission assembly 70 for connecting the rotating ring 20 is arranged on the mounting seat 41, the first transmission assembly 60 includes at least three friction wheels 61 being evenly arranged in the inside of the rotating ring 20 in the circumferential direction;Wherein, the lifting device 30 drives the sleeve ring 10 to move along the axial direction of the bridge pier, the friction wheel 61 generates friction force with the surface of the bridge pier to drive the rotating ring 20 to rotate, and the rotating ring 20 drives the mounting seat 41 to move along the annular slide 11 in the circumferential direction through the second transmission assembly 70.

[0031] It can be understood that by setting the lifting device 30 so that the sleeve ring 10 can move up and down along the pier, and by setting the spraying assembly 40 and the detection assembly 50 on the sleeve ring 10, the surface of the pier can be sprayed with a penetrating liquid and detected, thereby realizing the basic function of pier detection. In addition, in specific implementation, the rotating ring 20 inside the sleeve ring 10 is driven to rotate by the friction wheel 61, so that the rotating ring 20 drives the mounting seat 41 to slide on the annular slide 11 on the sleeve ring 10 through the second transmission assembly 70, so that the spraying assembly 40 and the detection assembly 50 on the mounting seat 41 also rotate around the pier, and then when the lifting device 30 drives the sleeve ring 10 to move up and down, the detection assembly 50 and the spraying assembly 40 will rotate around the pier while moving up and down. So that a single pier quality detection can realize comprehensive detection of the pier without the need to adjust the position and lift the quality detection device from different directions of the pier to comprehensively detect the pier, greatly improving the detection efficiency. Therefore, the utility model solves the problem of low detection efficiency of the existing pier quality detection device in the prior art.

[0032] Specifically, the first transmission assembly 60 further comprises a fixed seat 62 corresponding to the friction wheel 61, one end of the fixed seat 62 is provided with a groove 63 for accommodating the friction wheel 61, both sides of the friction wheel 61 are provided with shafts 64 connected with both sides of the groove 63, and the other end of the fixed seat 62 is connected with the rotating ring 20. Further, the friction wheel 61 is inclinedly arranged relative to the side wall of the groove 63, and a plurality of friction wheels 61 are circumferentially arranged around the axis of the rotating ring 20, so that the friction wheel 61 moves spirally forward and backward around the axis of the pier on the pier. In specific implementation, the friction wheel 61 is inclinedly arranged, so that when the friction wheel 61 moves on the pier, it moves in a spiral trajectory around the axis of the pier, thereby driving the rotating ring 20 to rotate. In addition, in the arrangement, each friction wheel 61 needs to be circumferentially arranged, that is, the orientations of each friction wheel 61 are consistent when moving, thereby ensuring that each friction wheel 61 cooperates with each other to drive the rotating ring 20 to rotate, avoiding interference between the friction wheels 61. In addition, the friction wheel 61 is fixed by the fixed seat 62, so that the friction wheel 61 is convenient to disassemble and replace. In addition, in specific implementation, the inclination angle of the friction wheel 61 can be adjusted to adjust the upward movement distance of the sleeve ring 10 and the angle of the friction wheel 61 relative to the axis of the pier, that is, to control the pitch of the spiral movement trajectory of the friction wheel 61. In order to adjust according to the needs, it is ensured that the spraying assembly 40 and the detection assembly 50 can cover each area of the pier.

[0033] In addition, the second transmission assembly 70 comprises a transmission rod 71 connected with the mounting base 41 and a gear 72 arranged on the transmission rod 71, and the rotating ring 20 is provided with an annular rack 21 matched with the gear 72. In the specific implementation, the rotating ring 20 rotates to drive the annular rack 21 to rotate, the annular rack 21 is engaged with the gear 72, thereby driving the gear 72 to move on the annular rack 21, and the gear 72 is connected with the mounting base 41 through the connecting rod, so that the mounting base 41 rotates around the pier, that is, moves along the sliding slide. Thus, the spraying assembly 40 and the detection assembly 50 move with the mounting base 41, so as to comprehensively detect the pier. In addition, in the specific implementation, a pulley can be arranged at the bottom of the mounting base 41, or the friction coefficient between the annular slide 11 and the mounting base 41 is adjusted, such as material adjustment or lubricant assistance, so that the friction between the mounting base 41 and the annular slide 11 is smaller.

[0034] In addition, the bottom of the rotating ring 20 is provided with an annular flange 22, and the inner side of the sleeve ring 10 is provided with an annular groove 12 matched with the annular flange 22, so that the rotating ring 20 can rotate around the sleeve ring 10. In the specific implementation, a bearing can also be arranged between the annular flange 22 and the annular groove 12, so that the rotating ring 20 can more easily rotate around the axis of the sleeve ring 10.

[0035] Specifically, the rotating ring 20 and the sleeve ring 10 are designed in a split manner, and the rotating ring 20 and the sleeve ring 10 each comprise two half rings 13 of different sizes, one end of the half ring 13 is provided with a fixed groove 131 at the bottom, the other end of the half ring 13 extends outwardly at the bottom and is provided with an extension 132 matched with the fixed groove 131, and the extension 132 and the fixed groove 131 are each provided with a mounting hole 133, so that the two half rings 13 are connected and fixed by fasteners.

[0036] In addition, the bottom of the mounting base 41 is provided with a wedge-shaped block 42, the annular slide 11 is provided with an annular slide groove 111 matched with the wedge-shaped block 42, and the cross-sectional area of the wedge-shaped block 42 gradually increases from the side close to the mounting base 41 to the other side. By arranging the wedge-shaped block 42 with gradually changing volume, the movement of the mounting base 41 along the annular slide groove 111 is limited, thereby avoiding the condition that the mounting base 41 moves too fast and flies out of the annular slide 11.

[0037] Specifically, the plurality of spraying assemblies 40 and the plurality of detecting assemblies 50 are distributed equidistantly around the axis of the sleeve ring 10. By arranging the plurality of spraying assemblies 40 and the plurality of detecting assemblies 50, the uniformity and efficiency of the spraying of the permeating liquid are improved, and the detection efficiency is improved. In addition, by arranging the spraying assemblies 40 and the detecting assemblies 50 alternately instead of arranging them together, the permeating liquid is prevented from being sprayed onto the detecting assemblies 50, thereby preventing damage to the detecting assemblies 50. By way of example but not limitation, in some optional embodiments, the sleeve ring 10 can be arranged as a multi-layer structure, adjacent sleeve rings 10 are supported and connected by connecting rods on the outside, the inside of each sleeve ring 10 is provided with a rotating ring 20, a first transmission assembly 60, a second transmission assembly 70, and a mounting seat 41, and the mounting seat 41 is provided with a spraying assembly 40 and a detecting assembly 50, respectively. When detecting, the bridge above is sprayed with the permeating liquid first, and the detecting assembly 50 below is detected subsequently. By arranging the sleeve ring 10 in layers, the number and position of the detecting assemblies 50 and the spraying assemblies 40 can be arranged more reasonably to meet the actual needs, and the problem that the detecting assemblies 50 and the spraying assemblies 40 are too close to each other and the permeating liquid affects the detecting assemblies 50 is avoided. In addition, the detecting assembly 50 generally includes a probe, and the spraying assembly 40 generally includes a spray head and a liquid storage pipe. The specific structure and arrangement of the detecting assembly 50 and the spraying assembly 40 are not the points to be protected by the present application, and the detecting assembly 50 and the spraying assembly 40 that are suitable for the mounting seat 41 can be directly purchased and installed. Therefore, the specific structure of the detecting assembly 50 and the spraying assembly 40 is not described in detail.

[0038] In addition, the bridge pier quality detection device further comprises a telescopic device, which is arranged on the rotating ring 20 and used to connect the fixing seat 62 and the rotating ring 20. By additionally arranging the telescopic device, the detection range of the bridge pier quality detection device is increased, and thus the bridge pier quality detection device can detect the bridge pier in a moving size range. Therefore, the versatility of the bridge pier quality detection device is improved.

[0039] Specifically, the lifting device 30 comprises a lifting platform 31, a lifting rod 32 connected to the lifting platform 31, and a mounting plate 33 arranged on the lifting rod 32 and used to mount the sleeve ring 10. The sleeve ring 10 on the mounting plate 33 is moved along the axis of the bridge pier by controlling the lifting rod 32 to move up and down by the lifting platform 31, thereby realizing comprehensive detection of the bridge pier.
