Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete detection, in particular to a water conservancy project concrete quality detection device. Background Art
[0002] The rebound test hammer is a comprehensive instrument for testing the strength of concrete. It is suitable for non-destructive testing of the compressive strength of ordinary concrete in various water conservancy projects.
[0003] First, when using the existing rebound hammer, the user needs to hold the rebound hammer in hand and put its detection end in contact with the concrete for detection. However, when the handheld rebound hammer is moved horizontally for detection, the user's hand is often unstable, which causes the detection end to slip from the concrete surface, resulting in errors in the detection results and reducing the detection effect of the device.
[0004] Second, when using the existing rebound tester, the user needs to hold the device in hand and contact the device with the concrete surface to be tested. Since the positions and heights of the points to be tested are different, the user needs to use tools to climb to the testing point when testing the concrete at a high place, which increases the operation steps and reduces the practicality of the device. Utility Model Content
[0005] The purpose of the utility model is to provide a water conservancy project concrete quality detection device to solve the problems raised in the above background technology.
[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a water conservancy project concrete quality detection equipment, comprising a rebound hammer for detecting concrete hardness; a connecting plate located at one end of the rebound hammer, the connecting plate is used to install the rebound hammer; side rods located at both sides of the rebound hammer, the side rods are used to drive the rebound hammer to move horizontally; clamping plates are clamped on the upper and lower sides of the rebound hammer, a movable plate is welded on the side of the clamp away from the rebound hammer, two movable plates are provided, an elastic member is bolted between the two movable plates, fixed blocks are welded on both sides of the connecting plate, a slider is bolted on the side of the fixed block away from the connecting plate, the slider is movably embedded in the side rod, a pressure plate is movably embedded on the top of the side rod, a lifting block is bolted on the side of the side rod away from the rebound hammer, the lifting block is movably embedded in the vertical pole, a rotating motor is bolted on the bottom of the vertical pole, a screw is bolted on the output end of the rotating motor, and the screw is threadedly connected to the lifting block.
[0007] Preferably, a rubber pad is bolted to one side of the clamping plate close to the rebound hammer, and the surface of the rubber pad is in close contact with the surface of the rebound hammer.
[0008] Preferably, a movable groove is formed on one side of the connecting plate close to the rebound hammer, and the two movable plates are movably engaged at the upper and lower sides of the movable groove.
[0009] Preferably, a sliding groove is formed on a side of the side rod close to the rebound hammer, the sliding block is movably engaged in the sliding groove, and a spring sheet is bolted to one side of the sliding block.
[0010] Preferably, a side of the spring sheet away from the sliding block is bolted in the sliding groove, and a communicating pressing groove is formed at the top of the sliding groove.
[0011] Preferably, the pressing plate is movably embedded in the pressing groove, and limiting rods are welded to the bottoms of both ends of the pressing plate, and the limiting rods are movably embedded on both sides of the side rods.
[0012] Preferably, a lifting groove is formed on the vertical pole, the lifting block is movably embedded in the lifting groove, and the bottom of the vertical pole is bolted to a base.
[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0014] First, align the detection end of the rebound tester with the detection point, so that the side of the base that faces the same direction as the detection end of the rebound tester is against the concrete surface. The user steps on the base with his foot and moves the detection end of the rebound tester toward the detection point. At this time, the slider will squeeze the spring piece in the slide groove, and the top of the spring piece will arch and push the pressure plate out of the pressure groove. When the detection end of the rebound tester contacts the concrete surface, hardness detection will be carried out. After the detection, the connecting plate will no longer be pushed. At this time, the pressure plate will drop by its own weight and press the spring piece back into the slide groove. The spring piece rebounds to its original state by its own elasticity and pushes the slider back to its original position, thereby bringing the rebound tester back to its original position to complete the detection. The cooperation of multiple components can reduce the steps for the user to hold the rebound tester for detection, make the rebound tester more stable during movement, and improve the detection effect.
[0015] Second, turn on the rotating motor, which drives the screw to rotate, and then drives the lifting block connected to the screw thread to move up and down in the lifting slot. The lifting block moves the rebound hammer to an appropriate height for use through the side rod. The user only needs to use the push rod of the corresponding height to push the rebound hammer without changing its own position. The rebound hammer with adjustable height can meet the needs of users to quickly detect the hardness of concrete at different heights, thereby improving the practicality of the device.

At this time, the slider 9 will squeeze the spring piece 12 in the slide groove 11, and the top of the spring piece 12 under force will arch and push the pressure plate 13 out of the pressure groove 15. When the detection end of the rebound tester 1 contacts the concrete surface, a hardness test will be performed. After the test, the connecting plate 2 will no longer be pushed.

[0029] Through the above technical solution, the spring piece 12 is made of a spring sheet material, and the middle portion of the spring piece 12 is in an upwardly arched shape.
[0030] Specifically, a side of the spring piece 12 away from the slider 9 is bolted in the slide slot 11 , and a communicating pressing groove 15 is formed at the top of the slide slot 11 .

[0033] Through the above technical solution, the pressure plate 13 is made of copper and has a certain weight. When the pressure plate 13 is not pushed upward by the spring sheet 12, it will press the spring sheet 12 back into the slide groove 11 by its own weight, and the limit rod 14 is used to keep the pressure plate 13 moving up and down in the vertical direction.
[0034] Specifically, a lifting groove 19 is formed on the vertical pole 17 , and the lifting block 16 is movably engaged in the lifting groove 19 . The bottom of the vertical pole 17 is bolted to a base 21 .

When the rebound test hammer 1 moves horizontally, it will squeeze the spring piece 12 in the slide groove 11 through the slider 9. The top of the spring piece 12 under force will arch and push the pressure plate 13 out of the pressure groove 15.
