Technical Field

[0001] The utility model relates to a wall strength detection device for construction engineering detection, belonging to the technical field of construction detection equipment. Background Technique

[0002] Wall tiles are provided for functions such as external protection and heat preservation of the wall. Wall tiles are widely used, but wall tiles are prone to many problems such as hollowing and falling off, seriously affecting safety and aesthetics. There is a lack of necessary supervision and inspection methods for the construction quality of wall tiles. Accidents of falling off, injuring people and causing property losses due to the bonding strength problem of the exterior wall facing tiles of buildings occur from time to time; for example, a wall tile bonding strength detection device with the Chinese patent publication number: CN218766557U mainly detects the tensile force between the bonding ends through a detector until the wall tile is pulled out from the wall. The combined use of the moving part and the detection connecting part improves the stability of the detection. However, in the prior art, its height cannot be effectively adjusted to quickly knock and detect the specified high wall surface, and the wall quality cannot be quickly and intuitively detected. Therefore, it is necessary to propose an improved wall strength detection device for construction engineering detection. Content of the Utility Model

[0007] Further improvement is: The crank-slider mechanism includes a crank cam installed inside the installation frame, and a driving motor installed outside the installation frame for driving the crank cam to rotate. The end of the crank cam is rotatably connected with a connecting rod, and the connecting rod is hinged to one side of the sliding block.

[0008] Further improvements are as follows: Cover plates are fixedly locked on the opposite sides of the knocking block and the slider. Both ends of the connecting rod penetrate through the two cover plates respectively, and the convex edge head is clamped inside the movable limiting groove through the cover plates.

[0009] Further improvements are as follows: A screw rod is rotatably installed at the bottom of the rectangular groove. An activity groove is provided at the bottom of the installation box body.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution for a wall strength detection device used in construction engineering detection: including an installation box body 1, a rectangular lifting cylinder 3 vertically installed in the middle of the installation box body 1, and a knocking component 4 installed on the top of the rectangular lifting cylinder 3; the knocking detection component 4 includes an installation frame 40 fixedly installed on the top of the rectangular lifting cylinder 3, a sliding groove 41 is provided on one side of the installation frame 40, a knocking block 42 and a slider 43 are slidably arranged in the sliding groove 41, and the knocking block 42 and the slider 43 are elastically connected. One side of the knocking block 42 protrudes outside the sliding groove 41. A crank-slider mechanism is provided in the installation frame 40 for pushing and pulling the slider 43 to reciprocate in the sliding groove 41. Opposite sides of the knocking block 42 and the slider 43 are respectively provided with movable limit grooves 48, and a connecting rod 49 is movably inserted through the two movable limit grooves 48. Both ends of the connecting rod 49 are provided with protruding edge heads 491 for being clamped at the outer notch of the movable limit grooves 48 of the knocking block 42 and the slider 43. The crank-slider mechanism includes a crank cam 44 installed inside the installation frame 40, and a driving motor 45 installed outside the installation frame 40 for driving the crank cam 44 to rotate. The end of the crank cam 44 is rotatably connected to a connecting rod 46, and the connecting rod 46 is hinged to one side of the slider 43. Cover plates 410 are fixedly installed on opposite sides of the knocking block 42 and the slider 43, which is convenient for later disassembly of the cover plates 410. Both ends of the connecting rod 49 respectively penetrate through the two cover plates 410, and the protruding edge heads 491 are clamped inside the movable limit grooves 48 through the cover plates 410. A screw rod 5 is rotatably installed at the bottom of the rectangular groove 2. An activity groove 7 is provided at the bottom of the installation box body 1. A rotating shaft 60 is installed inside the activity groove 7. A rotating motor 6 for driving the rotating shaft 60 to rotate is installed on one side of the installation box body 1. A driven bevel gear 51 is installed at the bottom of the screw rod 5. A driving bevel gear 61 meshing with the driven bevel gear 51 is installed on the rotating shaft 60. Two installation sleeves 8 are horizontally arranged on one side of the installation box body 1. A positioning plate 81 is vertically arranged on one side of the two installation sleeves 8. The positioning plate 81 is fixedly provided with a plug rod 82 that can be inserted inside the two installation sleeves 8, and a scale line 83 is provided on the surface of the plug rod 82. A return spring 84 is provided inside the installation sleeve 8, and one end of the plug rod 82 is elastically in contact with the return spring 84. By closely attaching the positioning plate 81 to the wall surface and observing according to the distance that the plug rod 82 penetrates into the installation sleeve 8, the scale line 83 on the plug rod 82 can be observed, so as to grasp the distance between the device and the wall surface, and enable the knocking detection component 4 to perform knocking detection better.

[0023] Four knocking springs 47 are connected between the knocking block 42 and the slider 43. Of course, the knocking springs 47 can also be replaced with elastic rubber air bags in the prior art, and only need to fix both ends of the rubber air bag on the opposite sides of the knocking block 42 and the slider 43 respectively.

[0024] Specific principle of use: Move the installation box body 1 to one side of the wall and make the alignment plate 81 closely adhere to the wall for alignment. Then, rotate the motor 6 to drive the rotating shaft 60, the driving bevel gear 61, the driven bevel gear 51 and the screw rod 5 in sequence, so that the screw rod 5 drives the rectangular lifting cylinder 3 to rise along the rectangular groove 2 through thread transmission, thereby adjusting the height of the upper side of the knocking detection component 4, so that the knocking block 42 of the knocking detection component 4 can correspond to the wall at a higher position. Then, based on the principle of the crank-slider mechanism, let the driving motor 45 drive the crank cam 44 to rotate, and the crank cam 44 drives the rotating connecting rod 46 to push and pull the slider 43 to reciprocate in the sliding groove 41. When the slider 43 pushes towards the knocking block 42, it can elastically push the knocking block 42 to displace towards the wall to knock through the knocking spring 47. In this way, the knocking uniformity of the wall is good, and it can be directly observed whether the paint drops or depresses, so as to judge the wall strength. When knocking, the displacement distance between the slider 43 and the knocking block 42 decreases, so that the connecting rod 49 between them retracts into the movable limiting groove 48; when the slider 43 is pulled towards the rotating connecting rod 46, the connecting rod 49 simultaneously slides out of the movable limiting grooves 48 of the slider 43 and the knocking block 42, and the protruding edge heads 491 at both ends are respectively stuck on the cover plate 410 connected outside the movable limiting grooves 48 of the slider 43 and the knocking block 42. In this way, when the slider 43 pulls back the knocking block 42, it can directly pull the knocking block 42 through the connecting rod 49, reducing the effect of pulling the knocking block 42 through the knocking spring 47. This pulling is not only more stable, but also can improve the service life of the knocking spring 47.

[0025] It should be noted that for a wall strength detection device for building engineering detection of the present utility model, its main structure has been improved. For functions, components and structures not mentioned, components and structures capable of realizing corresponding functions in the prior art can be adopted for implementation.
