Description

Technical Field

[0001] This utility model relates to the field of building testing equipment technology, specifically a reciprocating building wall strength testing machine. Background Technology

[0002] In the field of construction engineering, walls are an important component of building structures, and their strength is directly related to the stability, safety, and durability of buildings. From the quality control of new buildings to the maintenance and renovation of existing buildings, accurate testing of the strength of building walls is indispensable. Accurately assessing the strength of walls is a key link in ensuring that buildings meet safety standards and usage requirements.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219606453U) discloses a wall strength testing device for building construction, comprising a support frame, a moving mechanism at the bottom of one side of the support frame, a positioning mechanism at one side of the moving mechanism, an electric push rod fixed to the top of the support frame, a guide mechanism at the top of one side of the support frame, and a support platform fixedly connected to the output rod of the electric push rod. This utility model, through the support platform, support block, screw, rotating rod, threaded sleeve, contact plate, limiting mechanism, limiting sleeve, limiting rod, and wall strength detector, allows for better replacement of the testing machine according to different walls being tested. This avoids the problem of most wall strength testing devices for building construction being difficult to replace when testing different walls, thus bringing convenience to the use of wall strength testing devices for building construction.

[0004] While the aforementioned patent allows for better replacement of the inspection machine based on different walls through a support platform, support block, screw, rotating rod, threaded sleeve, contact plate, limiting mechanism, limiting sleeve, limiting rod, and wall strength detector, the position of the wall strength detector on the support platform is not adjustable. Furthermore, wall strength testing requires testing multiple points within the same area. Consequently, in practical use, the device necessitates frequent pushing of the entire unit by staff, making the operation cumbersome and increasing the workload of workers. This significantly reduces testing efficiency and delays construction progress.

[0005] Therefore, this utility model provides a reciprocating building wall strength testing machine to solve the above problems. Utility Model Content

A movable groove is provided on one side of the mounting shell. Two transmission wheels are symmetrically rotatably connected to the inner side of the mounting shell, and a synchronous belt is connected between the outer edges of the two transmission wheels. A limiting block is fixedly connected to the outer side of the synchronous belt, and a fixing rod is fixedly connected to the end of the limiting block. A detection component is fixedly connected to the top of the fixing rod.

[0008] As a preferred technical solution of this application, the lower surface of the mounting shell is fixed with a bracket A, and a drive motor B is fixedly connected to the inner side of the bracket A. The output shaft of the drive motor B passes through the interior of the mounting shell and is fixedly connected to the inner wall of one of the transmission wheels.

[0009] As a preferred technical solution of this application, the detection component includes a movable frame fixedly connected to a fixed rod, the inner wall of the bottom of the movable frame being slidably connected to the outer wall of the limiting guide rail, a fixed frame B fixedly connected to the outer wall of the movable frame, an electric push rod fixedly connected to the inner side of the fixed frame B, a fixed sleeve fixedly connected to the output end of the electric push rod through the inner wall of the movable frame, and a rebound spring fixedly connected to the inner side of the fixed sleeve.

[0010] As a preferred technical solution of this application, the movable frame has limit grooves on both sides, and the inner sides of the two limit grooves are respectively slidably adapted to the protrusions on both sides of the fixed sleeve.

[0011] As a preferred technical solution of this application, two sets of limiting strips are symmetrically fixedly connected to both sides inside the mounting shell, and the outer side between each pair of limiting strips abuts against the outer side of the timing belt.

[0012] As a preferred technical solution of this application, the inner side of the support frame is symmetrically fixedly connected with two limiting posts, and the outer walls of the two limiting posts are slidably connected to the outer wall of the connecting frame.

[0014] By activating drive motor A to rotate the lead screw, the screw engages with the connecting frame via a threaded connection, allowing the connecting frame to vertically raise and lower the detection assembly via the mounting housing. This adjusts the height of the detection assembly to accommodate wall surface inspection needs of varying heights. Through the transmission between two drive wheels and a drive belt, the synchronous belt drives a limiting block to move laterally along the inner side of the movable groove. This limiting block, via a fixed rod, causes the detection assembly to move laterally along the outer side of the limiting guide rail. Throughout the inspection process, the rebound hammer's inspection range can be adjusted to cover multiple inspection points on the wall surface without moving the entire device, significantly improving inspection efficiency and reducing the workload of personnel.

[0017] 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.

[0018] Please see Figures 1-5As shown, the purpose of this embodiment is to provide a reciprocating building wall strength testing machine, including a support frame 1, a drive motor A101 fixedly connected to the upper surface of the support frame 1, a lead screw 102 fixedly connected to the output end of the drive motor A101 through the inside of the support frame 1, a connecting frame 103 threadedly connected to the outside of the lead screw 102, and a mounting shell 2 fixedly connected to one side of the connecting frame 103. The upper surface of the mounting shell 2 is fixedly connected to a limiting guide rail 201. A movable groove 202 is provided on one side of the mounting shell 2. Two transmission wheels 203 are symmetrically rotatably connected to the inner side of the mounting shell 2, and a synchronous belt 204 is connected between the outer edges of the two transmission wheels 203. A limiting block 205 is fixedly connected to the outer side of the synchronous belt 204, and a fixing rod 206 is fixedly connected to the end of the limiting block 205. A detection component is fixedly connected to the top of the fixing rod 206.

[0019] In this embodiment, by activating the drive motor A101, the drive motor A101 drives the lead screw 102 to rotate inside the support frame 1. When the lead screw 102 rotates, it engages with the connecting frame 103 via a threaded connection, thereby driving the connecting frame 103 to move along the axial direction of the lead screw 102. This allows the connecting frame 103 to vertically raise and lower the detection assembly via the mounting housing 2, thus adjusting the height of the detection assembly to accommodate wall detection needs of different heights. Through the transmission between the two transmission wheels 203 and the transmission belt, the rotation of one of the transmission wheels 203 will... The synchronous belt 204 drives another transmission wheel 203 to rotate synchronously, so that the synchronous belt 204 transmits along the outer edge of the two transmission wheels 203. During the transmission process, the synchronous belt 204 drives the limiting block 205 to move laterally along the inner side of the movable groove 202. The limiting block 205 drives the detection component to move laterally along the outer side of the limiting guide rail 201 through the fixed rod. During the entire detection process, the detection range of the rebound hammer 304 can be adjusted to cover multiple detection points in the wall detection area without moving the entire device, thereby greatly improving detection efficiency and reducing the workload of the staff.

[0020] In this embodiment, as Figure 2 and Figure 3 As shown, the lower surface of the mounting housing 2 is fixed with a bracket A4. A drive motor B401 is fixedly connected to the inner side of the bracket A4, and the output shaft of the drive motor B401 passes through the interior of the mounting housing 2 and is fixedly connected to the inner wall of one of the transmission wheels 203.

[0021] In this embodiment, by starting the drive motor B401, the drive motor B401 will drive one of the transmission wheels 203 to rotate. While one transmission wheel 203 is rotating, it will drive the other transmission wheel 203 to rotate synchronously through the synchronous belt 204. In this way, the synchronous belt 204 can transmit power along the outer edge of the two transmission wheels 203. Then, the transmission of the synchronous belt 204 can cause the limit block 205 to drive the detection component to move laterally through the fixing rod 206, thereby completing the adjustment of the lateral detection range of the detection component.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the detection assembly includes a movable frame 3 fixedly connected to the fixed rod 206. The inner wall of the bottom of the movable frame 3 is slidably connected to the outer wall of the limiting guide rail 201. A fixed frame B301 is fixedly connected to the outer wall of the movable frame 3. An electric push rod 302 is fixedly connected to the inner side of the fixed frame B301. The output end of the electric push rod 302 passes through the inner wall of the movable frame 3 and is fixedly connected to a fixed sleeve 303. A rebound spring 304 is fixedly connected to the inner side of the fixed sleeve 303.

[0023] In this embodiment, when the movable frame 3 in the testing assembly moves the rebound hammer 304 along the outer side of the limiting guide rail 201 to the testing point via the fixed sleeve 303, the electric push rod 302 is activated. After activation, the electric push rod 302 will push the rebound hammer 304 towards the end opening of the movable frame 3 via the fixed sleeve 303, so that the rebound hammer 304 contacts the wall surface to test the strength of the wall surface, and record the test data in real time, thereby completing the wall surface strength test.

[0024] In this embodiment, as Figure 4 As shown, the movable frame 3 has limit grooves 5 on both sides, and the inner sides of the two limit grooves 5 are respectively adapted to slide with the protrusions on both sides of the fixed sleeve 303.

[0025] In this embodiment, the limiting grooves 5 on both sides of the movable frame 3 are slidably adapted to the protrusions on both sides of the fixed sleeve 303, which are used to guide and limit the movement of the rebound spring 304 inside the movable frame 3 when the fixed sleeve 303 drives it. This ensures that the rebound spring 304 is accurate when it performs detection work on the monitoring area under the push of the electric push rod 302, and avoids the rebound spring 304 from deviating during movement.

[0026] In this embodiment, as Figure 3 As shown, two sets of limiting strips 6 are symmetrically fixedly connected to both sides inside the mounting housing 2, and the outer side between each pair of limiting strips 6 abuts against the outer side of the synchronous belt 204.

[0027] In this embodiment, the limiting strip 6 is used to limit and support the outer edge of the synchronous belt 204, ensuring the stability of the synchronous belt 204 when it is transmitting power between the two transmission wheels 203, and preventing the synchronous belt 204 from shaking.

[0028] In this embodiment, as Figure 5 As shown, two limiting posts 7 are symmetrically fixedly connected to the inner side of the support frame 1, and the outer walls of the two limiting posts 7 are slidably connected to the outer wall of the connecting frame 103.

[0029] In this embodiment, the limiting post 7 is used to limit the vertical lifting of the connected cable inside the support frame 1, so as to ensure the stability of the connection frame 103 when the detection component moves up and down through the mounting shell 2.

[0030] In this embodiment, as Figure 1 As shown, a support plate 8 is fixedly connected to the bottom of the support frame 1, two sets of casters 9 are symmetrically fixedly connected to the lower surface of the support plate 8, and a handrail 10 is fixedly connected to the upper surface of the support plate 8.

[0031] In this implementation scheme, through the cooperation between the handrail 10 and the casters 9, when it is necessary to change the working area of ​​the device, simply push the handrail 10 so that the support plate 8 can drive the entire device to the designated testing area, thereby facilitating the transfer of the entire device.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
