Description

Technical Field

[0001] This utility model relates to the field of railway bridge grout density testing technology, specifically a railway bridge grout density testing device. Background Technology

[0002] In the railway transportation network, railway bridges are key hubs, and their engineering quality directly affects the safety of train operation and transportation efficiency. Grouting is a core part of railway bridge construction. Whether it is the reinforcement of bridge pier foundations or the filling of prestressed pipes, high-quality grouting can ensure that the bridge structure is tightly connected and shares the load. Grouting density is the core indicator for measuring grouting quality. If the density is insufficient, it will lead to uneven stress on the bridge structure, increase the risk of defects such as cracks and displacement, and even threaten traffic safety.

[0003] Currently, the grout density testing of railway bridges mostly uses a combination of grout density testing instruments and manual tapping. Manual tapping relies on the experience and technique of the testers, and the tapping force and frequency vary significantly among different personnel. Even the same tester cannot guarantee that the tapping force is completely consistent every time. Excessive force may damage the bridge structure, while insufficient force will not allow the vibration to be fully transmitted, resulting in unstable and inaccurate signals received by the testing instrument. In addition, the rhythm and position of manual tapping are highly random, making it difficult to achieve standardized operation and easily missing key testing points, leading to misjudgment or omission of defects. Therefore, there is an urgent need for a railway bridge grout density testing device to solve the above problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-3 This utility model provides a railway bridge grouting density testing device, including a main frame 1, a grouting density testing instrument installed on the top surface of the main frame 1, and further including: Tapping component 2 is installed on the inner wall of the main frame 1 and is used to work with the grouting density tester to uniformly tap the bridge test surface. Drive component 3 is located on the inner wall of the main frame 1 and is used to drive the striking component 2 in conjunction with the grouting density tester. Adjustment component 4 is located on the inner wall of the main frame 1 and is used to adjust the striking force of the striking component 2. Counterweight component 5 is installed on the inner wall of the main frame 1 and is used to position the main frame 1. The striking component 2 is designed to allow for uniform tapping of the bridge's test surface during grout density testing of railway bridges. This improves the accuracy of vibration signal propagation, reduces human error, and enhances testing precision. Furthermore, the driving component 3 facilitates the driving of the striking component 2, improving operational stability. Finally, the adjustment component 4 allows for adjustment of the striking force of the striking component 2 according to actual needs, thus enhancing overall practicality.

[0016] Furthermore, the striking assembly 2 includes a striking hammer 201, which is slidably connected to the inner wall of the main frame 1. A constraint frame 202 is slidably connected to the surface of the striking hammer 201, and the constraint frame 202 is fixedly connected to the inner wall of the main frame 1. A compression spring 203 is fitted onto the surface of the hammer 201. A connecting block 204 is fixedly connected to the left end of the hammer 201. A movable block 205 is rotatably connected to the inner wall of the connecting block 204. A connecting column 206 is rotatably connected to the inner wall of the movable block 205. A connecting plate 207 is rotatably connected to the surface of the connecting column 206. A rubber ring 208 is fixedly connected to the left end of the constraint frame 202. Through the set hammering component 2, the hammer 201 moves and pushes the compression spring 203 to contract and deform. When the hammer 201 is released, the compression spring 203 extends and releases the stored elastic force, thereby pushing the hammer 201 to move forward quickly. This allows the right end of the hammer 201 to strike the bridge surface to be inspected with uniform force, thereby improving the accuracy and stability of vibration signal propagation, reducing human experience errors, and improving detection accuracy.

[0017] Furthermore, the drive assembly 3 includes a drive column 301, which is rotatably connected to the inner wall of the main frame 1. A motor 302 is fixedly connected to the inner wall of the main frame 1. The surface of the drive column 301 is fixedly connected to the output end of the motor 302. A rotating disk 303 is fixedly connected to the surface of the drive column 301, and a toggle block 304 is fixedly connected to the surface of the rotating disk 303. Through the drive assembly 3, the output end of the motor 302 rotates at a constant speed, causing the drive column 301 and the rotating disk 303 to rotate at a constant speed. The constant rotation of the rotating disk 303 causes the toggle block 304 to toggle the connecting column 206 at the same rhythm, thereby improving the convenience and stability of use.

[0018] Furthermore, the adjusting component 4 includes a threaded post 401, which is rotatably connected to the inner wall of the main frame 1. A pushing block 402 is sleeved on the surface of the threaded post 401, and the pushing block 402 is slidably connected to the surface of the striking hammer 201. The right end of the compression spring 203 is fixedly connected to the left end of the pushing block 402. An adjusting nut 403 is threadedly connected to the surface of the threaded post 401, and the pushing block 402 is slidably connected to the striking hammer 201. A fixing nut 404 is threadedly connected to the surface of the threaded post 401, and the left end of the fixing nut 404 abuts against the right end of the pushing block 402. Through the adjusting component 4, the adjustment is made so that... Rotating the adjusting nut 403 moves the pushing block 402, which in turn moves the compression spring 203 in its initial state, thereby changing the release force of the subsequent elastic force. This allows for adjustment of the striking force of the striking component 2 according to actual needs, improving overall practicality. By using the fixed nut 404, after the pushing block 402 is adjusted, rotating the fixed nut 404 causes the left end of the fixed nut 404 to abut against the right end of the pushing block 402, thus facilitating the positioning of the adjusting nut 403 and ensuring stability during use after adjustment.

[0019] Furthermore, the counterweight assembly 5 includes a fixing frame 501, which is fixedly connected to the inner wall of the main frame 1. The surface of the fixing frame 501 is provided with a counterweight block 502, which is made of cement. The counterweight assembly 5 is used to position the main frame 1 by means of the counterweight block 502, thereby preventing the main frame 1 from moving during use. The counterweight block 502 is made of cement, which makes it easy to obtain materials and saves manufacturing costs.

[0020] Working principle: During use, the two testing ends of the grout density tester are tightly fitted to the bridge surface to be tested. Then, the hammer 201 of the testing equipment is placed against the striking point of the bridge surface. At the same time, the main frame 1 is positioned by adding a counterweight 502. Then, the hammer 201 moves through the set striking component 2, which pushes the compression spring 203 to contract and deform. When the hammer 201 is released, the compression spring 203 extends and releases the stored elastic force, thereby pushing the hammer 201 to move forward quickly. This allows the right end of the hammer 201 to strike the bridge surface to be tested with uniform force, thereby improving the accuracy and stability of vibration signal propagation, reducing human experience error, and improving testing accuracy.

[0021] Meanwhile, the drive assembly 3 ensures that the output of the motor 302 rotates at a constant speed, driving the drive column 301 and the rotating disk 303 to rotate at a constant speed. The rotating disk 303 rotates at a constant speed, causing the actuating block 304 to actuate the connecting column 206 in the same rhythm, thereby improving the convenience and stability of use. Secondly, by setting the adjustment component 4, rotating the adjustment nut 403 causes the push block 402 to move, which in turn changes the deformation of the compression spring 203 in its initial state, thereby changing the subsequent release force of the elasticity. This makes it easier to adjust the striking force of the striking component 2 according to actual needs, thus improving the overall practicality.
