Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a bridge crack depth detector. Background Technology

[0002] Bridges generally consist of a superstructure (also known as the bridge span structure, which is the main structure that crosses obstacles), a substructure (including abutments, piers, and foundations), bearings (force transmission devices installed at the support points between the bridge span structure and the piers or abutments), and ancillary structures (such as approach slabs, tapered slopes, revetments, and diversion works).

[0003] As described in announcement number CN220818813U, a bridge crack detection device belongs to the field of crack detection technology. It includes a base with a fixed structure on top and an adjustment structure on the top wall of the base. The fixed structure includes a detection plate on the top of the base, with graduations on the plate and a slider slidably connected inside. By using the fixed structure, a planar transducer of a concrete depth detector is placed on a placement block. Turning the left and right screws moves the placement block to a suitable position, and then activating the second electric telescopic rod brings the planar transducer into contact with the bridge surface to detect cracks. Through the placement block and the second electric telescopic rod, bridge cracks can be detected without personnel holding the planar transducer, effectively solving the problems of inconvenience in continuously holding the planar transducer due to the location of bridge cracks, and the inaccuracy caused by handheld detection.

[0004] This patent can improve the accuracy of detecting bridge cracks. However, existing detection devices often require operators to climb using A-frame ladders to place the detection probe close to the surface of the bridge pier when detecting cracks in the pier. This operation method is not only cumbersome, but also poses significant safety risks and threatens the safety of the operators.

[0005] Therefore, we propose a novel bridge crack depth detector. Utility Model Content

[0006] The purpose of this invention is to address the problem that existing detection devices for detecting cracks in bridge piers often require operators to climb using ladders to place the detection probe close to the pier surface. This method is not only cumbersome but also poses significant safety risks and threatens the safety of the operators.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a bridge crack depth detector, comprising a detector body, a connecting line connected to the top of the detector body, a detection head connected to one end of the connecting line, a telescopic adjustment assembly connected to the bottom of the detection head, the telescopic adjustment assembly comprising a main rod, a telescopic rod inserted inside the main rod, a connecting seat connected to the top of the telescopic rod, bolts inserted into the bottom of both sides of the connecting seat, an insertion hole on one side of the telescopic rod, a fixing block connected to the outer surface of one side of the main rod, two sets of springs connected inside the fixing block, push rods inserted inside the two sets of springs, handles connected to the rear ends of the two sets of push rods, push plates connected to the front ends of the two sets of push rods, and an insertion rod on one side of the push plate.

[0008] Furthermore, the outer surface of the telescopic rod is in contact with the inner wall of the detector body, and a sliding connection is formed between the telescopic rod and the detector body, so that the length of the telescopic rod can be adjusted through the sliding connection.

[0009] Furthermore, the position and size of the insertion rod match the position and size of the insertion hole, and the insertion rod and the insertion hole form a plug-in connection, which allows for quick and easy fixing of the length of the telescopic rod after adjustment.

[0010] Furthermore, the outer surface of the push plate is in contact with the inner wall of the fixing block, and the push plate and the spring form an elastic structure. The elastic structure can automatically push the push plate to drive the insertion rod to be inserted into the insertion hole for fixing.

[0011] Furthermore, a protective component is connected to the rear end of the main body of the detector. The protective component includes Velcro A and Velcro B, which can easily fix the arm.

[0012] Furthermore, the Velcro A and Velcro B are respectively connected to the upper and lower ends of the rear end of the detector body, and a handle is connected to one side of the rear end of the detector body, which can facilitate hand gripping.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when it is necessary to inspect cracks on bridge piers, the inspection head can be attached to the cracks on the bridge pier by adjusting the telescopic rod, eliminating the need to climb using an A-frame ladder, thus improving the safety of personnel when inspecting cracks.

[0015] 2. In this utility model, the arm is fixed by Velcro A and Velcro B to prevent the main body of the detector from being easily damaged during operation, and to avoid the risk of injury caused by the accidental detachment of the main body of the detector. Attached Figure Description

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1 - Figure 3As shown, this utility model provides a bridge crack depth detector, including a detector body 1. A connecting line 2 is connected to the top of the detector body 1, and a detection head 3 is connected to one end of the connecting line 2. A telescopic adjustment assembly 4 is connected to the bottom of the detection head 3. The telescopic adjustment assembly 4 includes a main rod 401, a telescopic rod 402 inserted inside the main rod 401, a connecting seat 404 connected to the top of the telescopic rod 402, bolts 405 inserted into the bottom of both sides of the connecting seat 404, an insertion hole 403 on one side of the telescopic rod 402, and a fixing block 406 connected to the outer surface of one side of the main rod 401. Two sets of springs 405 are connected inside the fixing block 406. 7. Push rods 408 are inserted into the interior of both sets of springs 407. Handles 411 are connected to the rear ends of the two sets of push rods 408. Push plates 409 are connected to the front ends of the two sets of push rods 408. Insert rods 410 are provided on one side of the push plate 409. The outer surface of the telescopic rod 402 is in contact with the inner wall of the detector body 1. The telescopic rod 402 and the detector body 1 form a sliding connection. The position and size of the insert rod 410 match the position and size of the insertion hole 403. The insert rod 410 and the insertion hole 403 form an insertion connection. The outer surface of the push plate 409 is in contact with the inner wall of the fixing block 406. The push plate 409 and the spring 407 form an elastic structure.

[0024] The overall effect of Embodiment 1 is that when it is necessary to detect the crack depth of the bridge pier, the connecting wires 2 can be connected to each other first, and then the connecting seat 404 can be directly attached to the bottom of the detection head 3 and fixed with bolts 405. When it is necessary to extend the telescopic rod 402, the handle 411 can be pulled outward, so that the handle 411 can drive the push plate 409 through the push rod 408 to compress the spring 407, so that the insertion rod 410 can be pulled out from the insertion hole 403 at the current height. Afterwards, slide and adjust the length of the telescopic rod 402. When the telescopic rod 402 is adjusted to a suitable length from the main body 1 of the detector, the handle 411 can be released, so that the spring 407 pushes the push plate 409 through its own elasticity, thereby driving the insertion rod 410 to be inserted into the insertion hole 403 for fixation. Then, grasp the main rod 401 and place the detection head 3 on the gap. The detection can be performed through the display on the main body 1 of the detector. There is no need to climb the ladder to operate, which improves the safety of personnel when detecting cracks.

[0025] Example 2, as Figure 1 and Figure 4 As shown, a protective component 5 is connected to the rear end of the detector body 1. The protective component 5 includes Velcro A501 and Velcro B502. Velcro A501 and Velcro B502 are respectively connected to the upper and lower ends of the rear end of the detector body 1. A handle 503 is connected to one side of the rear end of the detector body 1.

[0026] The effect achieved by the entire embodiment 2 is that when using the detector body 1, the left arm can be passed through Velcro A501 and Velcro B502 and fixed by Velcro A501 and Velcro B502. Then the left hand can grasp the handle 503, so as to avoid the detector body 1 from being easily damaged during operation and reduce the risk of injury caused by the detector body 1 accidentally falling off.

[0027] Working principle: When it is necessary to inspect the cracks on the bridge pier, the inspection head 3 can be attached to the crack of the bridge pier by adjusting the telescopic rod 402. There is no need to climb the ladder to operate, which improves the safety of personnel when inspecting cracks. The arm is fixed by Velcro A501 and Velcro B502 to prevent the main body of the inspection instrument 1 from being easily damaged during operation, and to avoid the risk of injury caused by the accidental detachment of the main body of the inspection instrument 1.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
