Description

Technical Field

[0001] This application relates to the field of concrete rebound hammers, and in particular to an auxiliary device for a concrete rebound hammer. Background Art

[0002] A concrete rebound hammer is a detection device, mainly used to detect the strength of general building components, bridges and various concrete components (such as slabs, beams, columns, and bridge trusses).

[0003] The basic principle of a concrete rebound hammer is to use a spring to drive a heavy hammer. The heavy hammer impacts a striker rod that is in perpendicular contact with the concrete surface with a constant kinetic energy, causing local concrete to deform and absorb part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is all converted into potential energy, the heavy hammer rebounds to the maximum distance, and the instrument displays the maximum rebound distance of the heavy hammer in the name of the rebound value (the ratio of the maximum rebound distance to the initial length of the spring).

[0004] During the test, it is necessary for the tester to keep the rebound hammer perpendicular to the concrete test surface. At the same time, the tester usually needs to conduct multiple rebound tests on the same plane. During multiple operations, due to long-term test operation, it is difficult for the tester to ensure the vertical state of the rebound hammer during the test, resulting in deviation of the test results. Utility Model Content

[0005] In order to solve the problem that it is difficult for the tester to ensure the vertical state of the rebound hammer during the test, resulting in deviation of the test results, this application provides an auxiliary device for a concrete rebound hammer.

[0006] The auxiliary device for a concrete rebound hammer provided by this application adopts the following technical solution:

[0007] An auxiliary device for a concrete rebound hammer includes a support frame. An installation frame is vertically slidably installed on the support frame. A first driving member for driving the installation frame to move is arranged on the support frame. A moving frame is horizontally slidably installed on the installation frame. A second driving member for driving the moving frame to move is arranged on the installation frame. An installation block is arranged on the moving frame. The rebound hammer is placed at the installation block and is slidably connected with the installation block. A locking member is slidably installed on one side of the installation block. One end of the rebound hammer is connected with the locking member. The installation block and the locking member are connected by an elastic member. A pushing member for pushing the rebound hammer to move is arranged on the moving frame.

[0008] By adopting the above technical solution, the rebound instrument is placed at the installation block, and one end of the rebound instrument is fixed at the locking member. At this time, the rebound instrument and the test surface are perpendicularly distributed to each other. The first driving member drives the mounting frame to move in the vertical direction, and the second driving member drives the moving frame to move in the horizontal direction to adjust the position of the rebound instrument. The pushing member pushes the rebound instrument to perform a rebound test on the test surface. During the test, the rebound instrument always remains perpendicular to the test surface, and the test result is relatively accurate.

[0009] Optionally, a moving plate is slidably mounted on the moving frame, a screw rod is rotatably mounted on the moving frame, the moving plate is threadedly connected to the screw rod, and the installation block is located on the moving plate.

[0010] By adopting the above technical solution, rotating the screw rod drives the moving plate to slide, adjusting the position of the moving plate and thus adjusting the position of the rebound instrument, which is suitable for performing rebound tests on different test surfaces.

[0011] Optionally, the first driving member includes a first motor and a first lead screw. The first lead screw is rotatably mounted on the support frame, the first motor is arranged on the support frame and drives the first lead screw to rotate. The mounting frame is threadedly connected to the first lead screw, and a guide rod is arranged on the support frame. The mounting frame is slidably connected to the guide rod.

[0012] By adopting the above technical solution, the first motor drives the first lead screw to rotate to drive the mounting frame to move up and down. The guide rod assists in guiding the movement of the mounting frame, adjusting the position of the mounting frame and thus adjusting the position of the rebound instrument, which is suitable for performing rebound tests on test areas at different heights on the test surface.

[0013] Optionally, the second driving member includes a second motor and a second lead screw. The second lead screw is rotatably mounted on the mounting frame, the second motor is arranged at one end of the mounting frame and drives the second lead screw to rotate, and the moving frame is threadedly connected to the second lead screw.

[0014] By adopting the above technical solution, the second motor drives the second lead screw to rotate, and the second lead screw drives the moving frame to move, adjusting the position of the rebound instrument on the moving frame in the horizontal direction. After the test of a test area at one position on the test surface is completed, the moving frame is driven to move to the adjacent test area for testing. After the horizontal test of a row of test areas is completed, the position of the mounting frame is adjusted to another row of test areas, and the tests are carried out successively in the horizontal direction. There is no need for manual adjustment to align the position of the test area, and the operation is relatively convenient.

[0015] Optionally, the locking member includes a fixing ring and a locking bolt. A ring groove for embedding one end of the locking bolt is arranged on the rebound instrument, and the fixing ring is slidably mounted on the moving plate.

[0016] By adopting the above technical solution, during installation, the ring groove at one end of the rebound hammer is placed on the fixing ring, and the locking bolt is rotated until one end is tightly pressed against the ring groove of the rebound hammer. At this time, the position between the rebound hammer and the fixing ring is fixed, and the fixing effect between the rebound hammer and the fixing ring is better.

[0017] Optionally, the elastic member includes a spring, one end of the spring is connected to the mounting block, and one end of the spring facing away from the mounting block is connected to the fixing ring.

[0018] By adopting the above technical solution, when the rebound hammer is pushed for testing, the fixed ring slides and causes the spring to stretch. After the test reading is completed, the rebound hammer is released, and the spring recovers, causing the rebound hammer and the fixed ring to automatically return to their original positions, facilitating the next test.

[0019] Optionally, a sliding rod is provided on one side surface of the fixing ring, the sliding rod is slidingly connected to the mounting block, and the spring is sleeved on the sliding rod.

[0020] By adopting the above technical solution, when the rebound hammer slides, the sliding rod on one side of the fixed ring slides with the mounting block, guiding and limiting the sliding of the fixed ring, and preventing it from shaking during testing.

[0021] Optionally, the pushing member includes a pushing rod and a pushing block, the pushing block is slidably mounted on the mounting block, one side of the pushing block is in contact with one end of the rebound hammer, and the pushing rod is arranged on a side of the pushing block away from the rebound hammer.

[0022] By adopting the above technical solution, during the test, the pushing rod is pushed to drive the pushing block to slide, and the pushing block pushes one side of the rebound hammer to slide to perform the rebound test, and the operation of driving the rebound hammer test is relatively convenient.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The rebound hammer is placed on the mounting block and one end is fixed on the fixing ring. The rebound hammer and the test surface are perpendicular to each other. The first driving member drives the mounting frame to move vertically, and the second driving member drives the moving frame to move horizontally. The position of the rebound hammer is adjusted, and the pushing member pushes the rebound hammer to perform a rebound test on the test surface. During the test, the rebound hammer always remains perpendicular to the test surface, and the test results are more accurate.

[0025] 2. The second screw drives the mobile frame to move and test the horizontal test areas one by one. After the test of one row of horizontal test areas is completed, the first screw is used to adjust the position of the mounting frame to another row of test areas for testing. There is no need to manually adjust the position of the test area, and the operation is more convenient.

[0026] 3. When pushing the rebound hammer for testing, the fixing ring slips to drive the spring to stretch. After reading the value after the test, release the rebound hammer. At this time, the spring returns, driving the rebound hammer and the fixing ring to automatically return to their original positions, facilitating the next test. Description of the Drawings

A second driving member 5 is provided on the mounting bracket 2. The second driving member 5 includes a second motor 51 and a second lead screw 52. The second lead screw 52 is horizontally rotatably mounted on the mounting bracket 2 and is arranged along the length direction of the mounting bracket 2. The second motor 51 is arranged at one end of the mounting bracket 2. The second motor 51 drives the second lead screw 52 to rotate, and the moving bracket 4 is threadedly connected to the second lead screw 52. The second motor 51 drives the second lead screw 52 to rotate, and the second lead screw 52 drives the moving bracket 4 to move.

[0035] Refer to Figure 1 And Figure 2 Refer to FIGS. and, on the moving bracket 4, a moving plate 41 is slidably mounted along the length direction of the moving bracket 4. The moving plate 41 and the second lead screw 52 are perpendicularly distributed to each other. On the moving bracket 4, a screw 42 is rotatably mounted along the length direction of the moving bracket 4. The moving plate 41 is threadedly connected to the screw 42. An installation block 43 is provided on the moving plate 41. The rebound instrument 9 is slidably mounted on the installation block 43. Rotating the screw 42 drives the moving plate 41 to slide, adjusting the position of the moving plate 41 and thus adjusting the position of the rebound instrument 9, which is suitable for performing rebound tests on test surfaces at different positions.

[0036] Refer to Figure 1 And Figure 2 Refer to FIGS. and, on one side of the moving plate 41 located at the installation block 43, a locking member 6 is provided. The installation block 43 and the locking member 6 are connected by an elastic member 7. On the side of the moving plate 41 facing away from the locking member 6, a pushing member 8 is provided. Place the rebound instrument 9 at the installation block 43. One end of the rebound instrument 9 is fixed at the locking member 6. At this time, the rebound instrument 9 and the test surface are perpendicularly distributed to each other. Adjust the position of the rebound instrument 9. The pushing member 8 pushes the rebound instrument 9 to perform a rebound test on the test surface. During the test, the rebound instrument 9 always remains perpendicular to the test surface, and the test result is relatively accurate. When the test on the test area on the test surface is completed, the second lead screw 52 drives the moving bracket 4 to drive the rebound instrument 9 on the moving plate 41 to move to the adjacent test area for testing. After the horizontal test areas in a row are tested, the first lead screw 32 drives the mounting bracket 2 to move, adjusting the position of the rebound instrument 9 in the vertical direction to another row of horizontal test areas, and then successively testing the test areas. There is no need to manually adjust and align the position of the test area, and the operation is relatively convenient.

[0037] Refer to Figure 3 The locking member 6 includes a fixing ring 61 and a locking bolt 62. A chute 411 is formed along the length direction on the moving plate 41. The fixing ring 61 is slidably mounted at the chute 411 and the fixing ring 61 is vertically arranged. A ring groove 91 is provided along the circumferential outer wall of the rebound instrument 9. During installation, place the ring groove 91 at one end of the rebound instrument 9 at the fixing ring 61, and rotate the locking bolt 62 until one end abuts against the ring groove 91 of the rebound instrument 9. At this time, the position between the rebound instrument 9 and the fixing ring 61 is fixed.

[0038] Reference Figure 3 The elastic member 7 includes a spring 71. One end of the spring 71 is connected to the mounting block 43, and the end of the spring 71 facing away from the mounting block 43 is connected to a side surface of the fixing ring 61. When the rebound hammer 9 is pushed to test, the fixing ring 61 slides and causes the spring 71 to stretch. After the test is completed and the rebound hammer 9 is released, the spring 71 recovers, causing the rebound hammer 9 and the fixing ring 61 to automatically return to their original positions, facilitating the next test.

[0039] Reference Figure 3 A sliding rod 611 is provided on one side of the fixing ring 61. The sliding rod 611 is slidably connected to the mounting block 43, and a spring 71 is mounted on the sliding rod 611. When the rebound hammer 9 slides, the sliding rod 611 on one side of the fixing ring 61 slides between the mounting block 43, guiding and limiting the sliding of the fixing ring 61, preventing it from shaking during testing.

[0040] Reference Figure 3 The pushing member 8 includes a pushing rod 81 and a pushing block 82. The pushing block 82 is slidably mounted on the mounting block 43. One side of the pushing block 82 abuts against one end of the rebound hammer 9. The pushing rod 81 is disposed on the side of the pushing block 82 facing away from the rebound hammer 9. Before testing, the pushing block 82 is slidably removed from the mounting block 43 and the rebound hammer 9 is installed. During testing, the pushing rod 81 is pushed to slide the pushing block 82. The pushing block 82 pushes one side of the rebound hammer 9 to slide and perform a rebound test. This makes the operation of driving the rebound hammer 9 for testing more convenient.

[0041] The implementation principle of the auxiliary device of the concrete rebound tester in the embodiment of the present application is as follows: the rebound tester 9 is placed on the mounting block 43, the position of the ring groove 91 and the locking bolt 62 are aligned, and the locking bolt 62 is rotated to lock the rebound tester 9 and the fixing ring 61. At this time, the first screw rod 32 and the second screw rod 52 drive the adjustment position of the rebound tester 9 until the rebound tester 9 corresponds to the test area position of the test surface, and the screw 42 is rotated to adjust the elastic rod at one end of the rebound tester 9 to fit the test surface. At this time, the pushing rod 81 is pushed to drive the rebound tester 9 to perform a rebound test on the test area of the test surface. After the test is completed, the spring 71 pushes the rebound tester 9 back to its position. At this time, the second screw rod 52 drives the moving frame 4 to the adjacent test area for testing. After the testing of one row of horizontal test areas is completed in sequence, the first screw rod 32 drives the mounting frame 2 to move to the position where the rebound tester 9 is located in another row of test areas, and tests are performed one by one in the horizontal direction until the rebound tests of all test areas are completed.
