Description

Technical Field

[0001] The utility model relates to the field of strength detection, in particular to a concrete strength automatic rebound detection robot. Background Art

[0002] Concrete strength testing is a process used to evaluate the compressive resistance of concrete structures. Concrete strength testing is crucial for construction projects and infrastructure construction. It can ensure the safety and reliability of concrete structures and improve project quality and durability. Non-destructive testing methods are usually used, including rebound method, ultrasonic method, resistance method, etc. These methods can accurately evaluate the strength of concrete without destroying the concrete structure. Among them, rebound method is the most commonly used method. The rebound hammer is applied to the concrete surface for impact, and the strength of the concrete is inferred based on the rebound degree of the rebound hammer.

[0003] When using the rebound method to test the strength of concrete, traditional concrete strength rebound testing devices generally use a handheld rebound tester to detect the position of the concrete. However, due to manual alignment of the test point, this will greatly increase the complexity and time cost of the operation, which may cause the test point to be inconsistent with the predetermined test area, affecting the accuracy of the test results, and increasing the risk of human error, which may lead to unreliable test results. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a concrete strength automatic rebound detection robot to solve the problem that the results of manual concrete strength automatic rebound detection in the prior art are unreliable.

[0005] To achieve the above object, the utility model provides a concrete strength automatic rebound detection robot, comprising a cart, a Z-axis drive module, a lifting seat, an X-axis drive module, a movable shell and a rebound detector;

[0006] The Z-axis drive module is installed on the cart;

[0007] The Z-axis driving module is connected to the lifting base to drive the lifting base to move along the Z-axis direction;

[0008] The X-axis drive module is installed on the lifting seat;

[0009] The X-axis driving module is connected to the movable shell to drive the movable shell to move along the X-axis direction;

[0010] The rebound detector can be detachably mounted on the movable shell.

[0011] By adopting this technical solution, after the rebound tester is installed on the movable shell, it can first be moved to the designated working area under the movement function of the cart itself, and then be moved freely on the moving surface formed by the Z-axis drive module and the X-axis drive module under the action of the Z-axis drive module and the X-axis drive module, so as to move the rebound tester to the designated detection position. Subsequently, the rebound tester can be used to perform automatic rebound detection at the corresponding position to ensure that the test point of the rebound tester is consistent with the predetermined detection area, thereby ensuring the accuracy of the test results and solving the problem of unreliable test results caused by errors in manually holding the rebound tester.

[0012] Furthermore, it also includes a drive shell installed on the cart, and the Z-axis drive module is installed inside the drive shell.

[0013] By adopting this technical solution, the installation complexity of the Z-axis drive module on the cart is reduced through the drive housing, while protecting the Z-axis drive module.

[0014] Furthermore, the Z-axis drive module includes a first motor, a first transmission wheel, a transmission belt, a second transmission wheel, a screw rod, a threaded sleeve, a sliding rod, a sliding sleeve and a connecting seat;

[0015] The first motor and the connecting base are an integrated structure and are connected to the drive housing through the connecting base;

[0016] The first transmission wheel and the second transmission wheel are respectively connected to the output shaft of the first motor and the lead screw, and the first transmission wheel and the second transmission wheel are connected in transmission via a transmission belt;

[0018] The threaded sleeve is fixed to the lifting seat and the sliding sleeve respectively. The threaded sleeve is threadedly connected to the screw rod, and the sliding sleeve is sleeved on the sliding rod.

[0019] By adopting this technical solution, after the first motor is started, the first transmission wheel connected to its output shaft drives the second transmission wheel to rotate through the transmission belt, thereby driving the screw to rotate. After the screw rotates, the threaded sleeve threaded on it can move up and down along the screw under the limiting action of the sliding sleeve and the sliding rod, thereby driving the lifting seat to move up and down, realizing the movement control in the Z-axis direction, and providing the prerequisite for the rebound tester to move in the Z-axis direction.

[0020] Furthermore, a second support frame is provided between one side of the drive housing and the top of the cart.

[0021] By adopting this technical solution, the second support frame is used for support to increase the stability of the drive housing on the cart.

[0022] Furthermore, the X-axis drive module includes a gear plate, a dual-axis motor, a gear, a limit sleeve and a limit rod;

[0023] The tooth plate is arranged horizontally and one end thereof is fixed to the lifting seat;

[0024] The dual-axis motor is installed inside the movable shell;

[0025] The gear is mounted on the output shaft of the dual-shaft motor, and the bottom end of the gear passes through the interior of the movable housing and engages with the gear plate;

[0026] The limiting sleeve is fixed to the bottom of the movable shell and is sleeved on the limiting rod;

[0027] The limiting rod is arranged parallel to the tooth plate and is fixed on the tooth plate.

[0028] By adopting this technical solution, after the dual-axis motor is started, the gear connected to its output shaft rotates. After the gear rotates, the movable shell can move along the tooth plate under the limiting action of the limit sleeve and the limit rod, thereby driving the movable shell to move along the X-axis on the tooth plate, providing the prerequisite for the rebound tester to move in the X-axis direction.

[0029] Furthermore, a first support frame is provided between the lower side of the tooth plate and the lifting seat.

[0030] By adopting this technical solution, the first support frame is used for support to increase the installation stability of the tooth plate on the lifting seat.

[0031] Furthermore, it also includes a card shell and a connecting block;

[0032] The card shell is movably connected to one side of the movable shell through a rotating shaft, and the other side of the movable shell is fixedly connected to a connecting block;

[0033] One side of the connecting block is clamped with the clamping shell.

[0034] By adopting this technical solution, after the rebound tester is placed on the movable shell, the clamping shell is flipped to the other side of the movable shell and engaged with the connecting block, and the rebound tester is tightened on the movable shell, thereby realizing rapid installation of the rebound tester. At the same time, the extension length of the rebound tester can be quickly adjusted, which can meet the needs of concrete strength testing under different situations.

[0035] Furthermore, the cart includes a bottom plate and a pulley, wherein the pulley is connected to the lower side of the bottom plate;

[0036] By adopting this technical solution, the cart is ensured to have the function of rapid movement.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The cooperation of the pallet, Z-axis moving module and X-axis moving module enables the rebound tester to move accurately to the predetermined testing position and ensure the accuracy of the testing position, thereby ensuring the accuracy of the test results and solving the problem of unreliable test results of manual handheld rebound testers.
