Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering testing technology, specifically a testing device for water conservancy engineering quality supervision. Background Technology

[0002] Quality inspection of water conservancy projects, or simply quality inspection, refers to the activities carried out by water conservancy project quality inspection units in accordance with relevant national laws, regulations, and standards. These activities involve inspecting, measuring, testing, or measuring the physical structure of water conservancy projects, as well as the raw materials, intermediate products, metal structures, and electromechanical equipment used in the projects. The results are then compared with relevant standards and requirements to determine whether the project quality is up to standard. Quality inspection of water conservancy projects inevitably involves testing the main structure of the projects, such as testing the compressive strength of the concrete in dams and bridges.

[0003] In existing water conservancy projects, concrete inspection is generally carried out using a rebound hammer. However, the applicant found that before testing with the rebound hammer, personnel need to draw a cross grid in the test area and then perform rebound tests on the grid areas one by one. This operation is cumbersome, especially the drawing of the cross grid. In order to simplify the operation, an inspection device for quality supervision of water conservancy projects is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an inspection device for quality supervision of water conservancy projects in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: A quality supervision and inspection device for water conservancy projects includes a rebound hammer for testing the compressive strength of concrete in water conservancy projects. A collar is fitted onto the rebound hammer, and a locking bolt is threaded onto the outer wall of the collar. Two support plates are symmetrically fixedly connected to the outer wall of the collar. A guide rod is slidably connected to the support plate, and a return spring is fitted onto the guide rod. A stop block is fixedly connected to one end of the guide rod, and a square plate is detachably threaded onto the other end of the guide rod. A square ring-shaped sponge for absorbing ink is fixedly connected to one side of the square plate, and positioning protrusions are fixedly connected to both ends of each side of the square plate.

[0006] In a preferred embodiment, a raised retaining ring is formed on the outer wall of the rebound spring.

[0007] In a preferred embodiment, the square plate has a square hole.

[0008] In a preferred embodiment, a handle is fixedly connected to one of the support plates.

[0009] In a preferred embodiment, a handle 2 is fixedly installed at the tail of the rebound device.

[0010] In a preferred embodiment, the second handle and the support plate are arranged perpendicularly.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, compared with the prior art, it is not necessary for technicians to draw a positioning cross grid on the concrete in advance, which simplifies the measurement operation. At the same time, in this application, the measurement point of the rebound hammer is always in the center of the measurement grid, thereby improving the detection accuracy.

[0013] 2. In this utility model, the locking bolts are loosened, and then the collar can be removed from the springback device.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The following will combine Figures 1-3 A detailed description is provided of an inspection device for quality supervision of water conservancy projects according to an embodiment of this utility model.

[0020] Example:

[0021] This utility model provides an inspection device for quality supervision of water conservancy projects, with reference to... Figures 1 to 3As shown, the device includes a rebound hammer 1 for testing the compressive strength of concrete in hydraulic engineering. A collar 2 is fitted onto the rebound hammer 1, and a locking bolt 3 is threaded onto the outer wall of the collar 2. Two support plates 4 are symmetrically fixed to the outer wall of the collar 2. A guide rod 5 is slidably connected to the support plate 4, and a return spring 6 is fitted onto the guide rod 5. A square plate 7 is detachably threaded to one end of the guide rod 5. A square annular sponge 8 for absorbing ink is fixedly connected to one side of the square plate 7. Positioning protrusions 9 are fixedly connected to both ends of each side of the square plate 7. This structure constitutes a concrete strength testing device for hydraulic engineering dams. In use, the operator first absorbs sufficient ink into the square annular sponge 8. Then, the operator aligns the square annular sponge 8 on the square plate 7 with the concrete to be tested in the dam. The operator then continuously pushes the rebound hammer 1 inwards towards the concrete. At this time, the telescopic rod of the rebound hammer 1... The material will be squeezed back into the rebound hammer 1. Once fully retracted, the dam concrete can be rebound tested. During the operation of the rebound hammer 1, the rebound hammer 1 will push the return spring 6 to squeeze the square plate 7, thereby causing the square annular sponge 8 to adhere to the dam concrete. After the measurement is completed, a square mark will be left on the surface of the dam concrete. When measuring the next point, the operator only needs to align the positioning protrusion 9 with two sides of the previous square mark and align the square plate 7 with one side of the square mark. Then the measurement operation can be repeated. By repeating the above operation, the dam concrete can be tested at multiple points in a grid pattern. Compared with the existing technology, the operator does not need to draw a positioning cross grid on the concrete in advance, which simplifies the measurement operation. At the same time, in this application, the measurement point of the rebound hammer 1 is always in the center of the measurement grid, thereby improving the accuracy of the test.

[0022] Furthermore, when the above structure is not in use, personnel can loosen the locking bolt 3, and then remove the collar 2 from the springback device 1. Then, personnel can remove the guide rod 5 from the reverse plate 7, thereby disassembling the entire printing frame mechanism for easy storage and carrying.

[0023] It should be noted that the above-mentioned square ring-shaped sponge 8 can print multiple squares at once, meeting the needs of a single test.

[0024] refer to Figures 1 to 3 As shown, a stop block 14 is fixedly connected to one end of the guide rod 5. This structure uses the stop block 14 to prevent the guide rod 5 from detaching from the support plate 4.

[0025] refer to Figures 1 to 3 As shown, a raised retaining ring 10 is constructed on the outer wall of the rebounder 1, and the raised retaining ring 10 is used to position the positioning collar 2.

[0026] refer to Figures 1 to 3 As shown, a square hole 11 is provided on the square plate 7. This structure allows the rebound hammer 1 to pass through the square plate 7 and come into contact with the dam concrete.

[0027] refer to Figures 1 to 3As shown, a handle 12 is fixedly connected to one of the support plates 4, and a handle 23 is fixedly installed at the tail of the rebounder 1. With this structure, handle 12 is convenient for the person to hold with their left hand, and handle 23 is convenient for the person to hold with their right hand.

[0028] refer to Figures 1 to 3 As shown, the handle 13 and the support plate 4 are arranged vertically, which prevents the handle 13 from interfering with the guide rod 5.

[0029] It should be noted that the above-mentioned concrete rebound hammer 1 is used for concrete strength testing of dams in water conservancy projects, and the rebound hammer 1 is a publicly disclosed device. For specific models, please refer to HT-225A. You can also refer to the structure of the rebound hammer 1 disclosed on the patent website. This application does not make any improvements to the specific structure of the rebound hammer 1, so it will not be described in detail here.

[0030] The implementation principle of a water conservancy project quality supervision and inspection device according to an embodiment of this application is as follows: During use, the operator first absorbs sufficient ink into the square annular sponge 8. Then, the operator aligns the square annular sponge 8 on the square plate 7 with the concrete of the dam to be inspected. The operator then continuously pushes the rebound hammer 1 inwards towards the concrete. At this time, the telescopic rod of the rebound hammer 1 is squeezed and retracted into the rebound hammer 1. Once fully retracted, the dam concrete rebound test can be performed. During the operation of the rebound hammer 1, the rebound hammer 1 pushes the return spring 6 to squeeze the square plate 7, thereby causing the square annular sponge 8 to... The dam concrete is bonded together, so that after the measurement is completed, a square mark will be left on the surface of the dam concrete. Then, when measuring the next point, the personnel only need to align the positioning protrusion 9 with two sides of the previous square mark and align the square plate 7 with one side of the square mark. Then the measurement operation can be repeated. By repeating the above operation, the dam concrete can be inspected in a grid pattern. Compared with the existing technology, the personnel do not need to draw a positioning cross grid on the concrete in advance, which simplifies the measurement operation. At the same time, in this application, the rebound hammer is always in the center of the measurement grid, thereby improving the accuracy of the detection.

[0031] Furthermore, when the above structure is not in use, personnel can loosen the locking bolt 3, and then remove the collar 2 from the springback device 1. Then, personnel can remove the guide rod 5 from the reverse plate 7, thereby disassembling the entire printing frame mechanism for easy carrying, storage, and transport.
