Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hollow detection technology, and specifically relates to a device for detecting hollow areas in concrete. Background Technology
[0002] Hollow areas in concrete are caused by improper concrete pouring, vibration, curing, or base treatment, resulting in gaps or voids inside the concrete, on its surface, or between the concrete and the base. The key to preventing hollow areas is to strictly control the concrete mix ratio, optimize the pouring and vibration process, thoroughly treat the base, ensure the quality of the formwork, and provide timely and adequate curing.
[0003] In existing technologies, a striking ball is usually fixed to one end of a rod so that the striking ball can strike the surface of the concrete for detection. The sound generated during the striking process can be used to distinguish whether there are hollow areas inside the concrete. However, striking the concrete for a long time can easily cause fatigue to the workers, thereby reducing the efficiency of detecting hollow areas in the concrete. Utility Model Content
[0004] To address the issue that detecting internal hollowness in concrete involves fixing a striking ball to one end of a rod to strike the concrete surface, using the sound generated during the striking process to identify whether there are hollow areas inside the concrete, but prolonged striking of the concrete can easily cause fatigue for workers, thus reducing the efficiency of concrete hollowness detection, this utility model proposes a concrete hollowness detection device to overcome the aforementioned technical problems existing in related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a device for detecting hollow areas in concrete, including a base plate:
[0007] The base plate is equipped with a drive assembly, a transmission assembly, a lifting assembly, a striking assembly, and a moving assembly.
[0008] The drive component has its output end fixedly mounted to one end of the transmission component, so that the drive component drives the transmission component to rotate.
[0009] The lifting component is fixedly mounted on its outer surface to the interior of the transmission component, so that the transmission component drives the lifting component to operate;
[0010] The striking component is fixedly connected at its top to the outer surface of the lifting component, so that the lifting component can drive the striking component to strike the concrete.
[0011] The top of the movable component is fixedly connected to the bottom of the base plate, so that the movable component can drive the base plate to move.
[0012] Furthermore, the drive assembly includes a mounting bracket, the bottom end of which is fixedly connected to the top end of the base plate, and a motor is fixedly mounted on one side of the mounting bracket.
[0013] Furthermore, the transmission assembly includes a support frame, one side of which is fixedly connected to one side of the mounting frame. A worm gear is rotatably mounted inside the support frame, one end of which is fixedly mounted to the output end of the motor. A worm wheel is meshed with the surface of the worm gear.
[0014] Furthermore, the lifting assembly includes a connecting shaft, the outer surface of the connecting shaft is rotatably mounted to the interior of the mounting bracket, the outer surface of the connecting shaft is fixedly mounted to the interior of the worm gear, a push block is fixedly mounted on the outer surface of the connecting shaft, and a lifting rod is fitted onto the outer surface of the push block.
[0015] Furthermore, the striking assembly includes a fixed frame, the bottom end of which is fixedly installed to the top end of the base plate. A connecting rod is slidably arranged inside the fixed frame, the top end of which is fixedly connected to the outer surface of the lifting rod. A hollow hammer is fixedly connected to the bottom end of the connecting rod, and a spring is fixedly connected inside the hollow hammer. The top end of the spring is fixedly connected to the bottom end of the fixed frame.
[0016] Furthermore, the striking assembly also includes a mounting groove and a limiting groove. The mounting groove is formed inside the fixing frame, and a limiting rod is fixedly installed inside the mounting groove. The limiting groove is formed on the outer surface of the connecting rod, and the inside of the limiting groove is slidably set with the outer surface of the limiting rod.
[0017] Furthermore, the movable component includes a rotating base, the top of which is fixedly connected to the bottom of the base plate, and an installation shaft is rotatably mounted inside the rotating base, with rollers fixedly mounted on the outer surface of the installation shaft.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model drives the transmission component installed at the output end of the start-up drive component to rotate, so that the transmission component drives the lifting component installed inside to move upward, thereby enabling the lifting component to drive the tapping component fixed on the outer surface to move upward. When the lifting component rises to the highest point, it can detach itself and then move downward under the action of the tapping component's own reset, so that the tapping component can tap the concrete. This avoids long-term manual tapping of the concrete, thereby improving the detection efficiency of concrete hollowness.
[0020] 2. In this utility model, when the lifting rod moves upward by the rotation of the push block, the lifting rod can move the connecting rod fixed on the outer surface. Since the outer surface of the connecting rod has a limiting groove, and the inside of the limiting groove is slidably set with the outer surface of the limiting rod, when the connecting rod moves with the limiting groove, the connecting rod can rotate along the direction of the limiting rod, thereby preventing the connecting rod from rotating during the movement. When the connecting rod moves upward, it can move the hollow hammer fixed at the bottom, so that the hollow hammer can compress the spring fixed at the top. When the lifting rod is separated from the push block, the spring can release the compressive stress, so that the spring can push the hollow hammer to knock on the concrete, thereby facilitating the detection of hollow areas in the concrete.
[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0033] Please see Figures 1-6 As shown, this utility model is a device for detecting hollow areas in concrete, including a base plate 1:
[0034] The base plate 1 is respectively equipped with a drive assembly 2, a transmission assembly 3, a lifting assembly 4, a striking assembly 5, and a moving assembly 6;
[0035] The output end of the drive component 2 is fixedly installed at one end of the transmission component 3 so that the drive component 2 drives the transmission component 3 to rotate.
[0036] The lifting component 4 is fixedly installed on its outer surface and inside the transmission component 3 so that the transmission component 3 drives the lifting component 4 to operate.
[0037] The striking component 5 is fixedly connected to the outer surface of the lifting component 4 at its top end, so that the lifting component 4 drives the striking component 5 to strike the concrete.
[0038] The top of the movable component 6 is fixedly connected to the bottom of the base plate 1 so that the movable component 6 can drive the base plate 1 to move.
[0039] In use, by pushing the base plate 1, it moves on the concrete surface in conjunction with the movable component 6 fixed at the bottom. Then, the drive component 2 is activated to drive the transmission component 3 installed at the output end to rotate, so that the transmission component 3 drives the internally installed lifting component 4 to move upward. This allows the lifting component 4 to drive the outer surface fixed striking component 5 to move upward. When the lifting component 4 rises to the highest point, it can detach itself and then move downward under the self-resetting action of the striking component 5, so that the striking component 5 can strike the concrete. This allows the analysis of whether there are hollow areas in the concrete based on the striking sound.
[0040] This invention drives the transmission component 3 installed at the output end of the drive component 2 to rotate, so that the transmission component 3 drives the lifting component 4 installed inside to move upward. This allows the lifting component 4 to drive the striking component 5 fixed on the outer surface to move upward. When the lifting component 4 rises to the highest point, it can detach itself and then move downward under the self-resetting action of the striking component 5, so that the striking component 5 can strike the concrete. This avoids the need for long-term manual striking of the concrete, thereby improving the detection efficiency of hollow concrete.
[0041] In one embodiment, the drive assembly 2 includes a mounting bracket 201, the bottom end of which is fixedly connected to the top end of the base plate 1, and a motor 202 is fixedly mounted on one side of the mounting bracket 201.
[0042] The mounting bracket 201 is designed to support the motor 202 mounted on one side, thereby improving the stability of the motor 202 during operation.
[0043] In one embodiment, the transmission assembly 3 includes a support frame 301, one side of which is fixedly connected to one side of the mounting frame 201. A worm gear 302 is rotatably disposed inside the support frame 301. One end of the worm gear 302 is fixedly installed to the output end of the motor 202. A worm wheel 303 is meshed with the surface of the worm gear 302.
[0044] The worm 302 installed at the output end is driven to rotate by starting the motor 202. Since the outer surface of the worm 302 is rotated with the inside of the support frame 301, and the surface of the worm 302 meshes with the surface of the worm wheel 303, when the worm 302 rotates, it can drive the worm wheel 303 to rotate with the inside of the support frame 301 as the center.
[0045] In one embodiment, the lifting assembly 4 includes a connecting shaft 401, the outer surface of the connecting shaft 401 is rotatably disposed with the interior of the mounting bracket 201, the outer surface of the connecting shaft 401 is fixedly installed with the interior of the worm gear 303, a push block 402 is fixedly installed on the outer surface of the connecting shaft 401, and a lifting rod 403 is attached to the outer surface of the push block 402.
[0046] When the worm gear 303 rotates, it drives the internally mounted connecting shaft 401 to rotate. Since the outer surface of the connecting shaft 401 is rotatably mounted to the inside of the mounting bracket 201, and the outer surface of the connecting shaft 401 is fixedly mounted to the inside of the push block 402, when the connecting shaft 401 rotates, it drives the push block 402 to rotate around the inside of the mounting bracket 201 as the center. This causes the arc end of the push block 402 to push the lifting rod 403 upward. When the push block 402 drives the lifting rod 403 to move to the highest point, the push block 402 disengages from the lifting rod 403, making it easier for the lifting rod 403 to fall. This facilitates subsequent lifting of the lifting rod 403, making it more convenient.
[0047] In one embodiment, the striking component 5 includes a fixing frame 501, the bottom end of which is fixedly installed to the top end of the base plate 1. A connecting rod 502 is slidably arranged inside the fixing frame 501. The top end of the connecting rod 502 is fixedly connected to the outer surface of the lifting rod 403. A hollow hammer 503 is fixedly connected to the bottom end of the connecting rod 502. A spring 504 is fixedly connected inside the hollow hammer 503. The top end of the spring 504 is fixedly connected to the bottom end of the fixing frame 501.
[0048] The striking assembly 5 also includes a mounting groove 505 and a limiting groove 506. The mounting groove 505 is formed inside the fixing frame 501. A limiting rod 507 is fixedly installed inside the mounting groove 505. The limiting groove 506 is formed on the outer surface of the connecting rod 502. The inside of the limiting groove 506 is slidably disposed with the outer surface of the limiting rod 507.
[0049] When the lifting rod 403 moves upward with the rotation of the push block 402, it can drive the connecting rod 502 fixed on the outer surface to move. Since the outer surface of the connecting rod 502 has a limiting groove 506, and the inside of the limiting groove 506 is slidably set with the outer surface of the limiting rod 507, when the connecting rod 502 drives the limiting groove 506 to move, the connecting rod 502 can rotate along the direction of the limiting rod 507, thereby preventing the connecting rod 502 from rotating during the movement. When the connecting rod 502 moves upward, it can drive the hollow hammer 503 fixed at the bottom to move, so that the hollow hammer 503 compresses the spring 504 fixed at the top. When the lifting rod 403 is separated from the push block 402, the spring 504 can release the compressive stress, so that the spring 504 can push the hollow hammer 503 to knock on the concrete, thereby facilitating the detection of hollow concrete.
[0050] In one embodiment, the moving component 6 includes a rotating seat 601, the top end of which is fixedly connected to the bottom end of the base plate 1. An installation shaft 602 is rotatably arranged inside the rotating seat 601, and a roller 603 is fixedly installed on the outer surface of the installation shaft 602.
[0051] Since the base plate 1 has a handle inside, pushing the handle will move the base plate 1, which in turn moves the rotating seat 601 fixed at the bottom. This causes the rotating seat 601 to move the mounting shaft 602 inside, which in turn drives the roller 603 to roll on the concrete surface, so as to move the base plate 1.
[0052] Through the above technical solution, 1. The drive component 2 drives the transmission component 3 installed at the output end to rotate, so that the transmission component 3 drives the lifting component 4 installed inside to move upward. This allows the lifting component 4 to drive the tapping component 5 fixed on the outer surface to move upward. When the lifting component 4 rises to the highest point, it can detach itself and then move downward under the action of the tapping component 5's self-reset, so that the tapping component 5 can tap the concrete. This avoids long-term manual tapping of the concrete, thereby improving the detection efficiency of concrete hollowness.
[0053] 2. When the lifting rod 403 moves upward by the rotation of the push block 402, the lifting rod 403 can move the connecting rod 502 fixed on the outer surface. Since the outer surface of the connecting rod 502 has a limiting groove 506, and the inside of the limiting groove 506 is slidably set with the outer surface of the limiting rod 507, when the connecting rod 502 moves with the limiting groove 506, the connecting rod 502 can rotate along the direction of the limiting rod 507, thereby preventing the connecting rod 502 from rotating during the movement. When the connecting rod 502 moves upward, it can move the hollow hammer 503 fixed at the bottom, so that the hollow hammer 503 compresses the spring 504 fixed at the top. When the lifting rod 403 is separated from the push block 402, the spring 504 can release the compressive stress, so that the spring 504 can push the hollow hammer 503 to knock on the concrete, thereby facilitating the detection of hollow concrete.
