Description

Technical Field

[0001] This utility model relates to the field of shear wave testing equipment, specifically a shear wave tester with a retractable probe. Background Technology

[0002] Shear wave velocity testers use hammering, electric sparks, or explosions as excitation sources. They can be used to explore depths from a few meters to over a hundred meters. With a delay function, the accuracy of vibration signals in deep strata can be guaranteed. They are suitable for wave velocity testing. Existing tester probes cannot be buffered and retracted, making them prone to damage upon impact.

[0003] According to patent document CN215297691U, a shear wave velocity tester with probe storage is disclosed. It includes a tester body and a protective case. The tester body is housed inside the protective case, and an opening is provided on one side of the protective case. A storage box is slidably connected within the opening. The storage box contains two partitions. Two first elastic bands are fixedly connected to the middle of the upper inner wall of the storage box, and two second elastic bands are fixedly connected to one side of the upper inner wall of the storage box. A spare probe is secured by both second elastic bands. This technical solution allows for quick probe replacement via the storage box, and the second elastic bands secure the spare probe, facilitating replacement when the test probe is damaged. However, while this solution enables rapid probe replacement, it lacks cushioning protection during probe descent and cannot protect the probe during brief device movements, causing inconvenience in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a shear wave tester with a retractable probe to solve the problems mentioned in the background. This invention features a novel structure. When the fixed box needs to be moved a short distance, the cable is wound up on a winch. As the cable winding support moves to the side of the fixed box, the support provides a limit for the support tube. Under the tension of the cable, the probe retracts inside the support tube for protection, thus avoiding damage caused by probe collisions during short-distance movement.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a probe-extendable shear wave tester, comprising a fixed box, a movable box hinged to one end of the fixed box, a test mechanism embedded inside the movable box, a display screen fixedly mounted on the test mechanism, a button fixedly mounted at the bottom of the display screen, a cavity inside the fixed box, a fixed plate fixed inside the cavity, a winch wheel rotatably mounted between the fixed plates, a drive motor fixedly mounted on one side of the fixed plate, and a cable wound around the winch wheel.

[0006] Furthermore, a support tube is movably installed on the cable, and a probe is movably installed inside the support tube. The probe is fixedly installed at one end of the cable.

[0007] Furthermore, a baffle is welded to the inner wall of the cavity, and a movable plate is movably installed on the top of the baffle, with a partition plate fixed on the movable plate.

[0008] Furthermore, the fixed box has an opening on its side, the cable is movably installed inside the opening, and a support base is movably installed on the side of the fixed box.

[0009] Furthermore, the support base has a fixing groove, and a fixing block is movably installed inside the fixing groove. A limit bolt is rotatably installed on the fixing block.

[0010] Furthermore, a limiting groove is opened on the side of the support base, the limiting bolt is movably installed inside the limiting groove, and a fixing tube is fixed on one side of the fixing block.

[0011] Furthermore, a ring seat is movably installed inside the support tube. The ring seat is installed inside the support tube by a support mechanism, and the ring seat is movable in conjunction with the probe.

[0012] Furthermore, the fixed tube has an installation groove inside, and a roller is rotatably installed inside the installation groove, the roller being in contact with the cable.

[0013] The beneficial effects of this utility model are:

[0014] 1. This telescopic shear wave tester allows the cable to be wound up on a winch when the fixed box needs to be moved a short distance. As the cable winding support moves to the side of the fixed box, the support provides a limit for the support tube. Under the tension of the cable, the probe retracts inside the support tube for protection, avoiding damage caused by probe collision during short-distance movement.

[0015] 2. In this telescopic shear wave tester, when the probe is installed inside the borehole, the support base is installed at the top of the borehole to provide support for the descent of the cable, so that the support tube and the probe descend along the center of the borehole. During the descent of the cable, the rollers provide support for the cable and reduce friction damage to the cable. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a shear wave tester with a retractable probe, including a fixed box 1, a movable box 5 hinged to one end of the fixed box 1, a testing mechanism 6 embedded inside the movable box 5, the testing mechanism 6 being the body of the shear wave tester, the wave velocity being tested through the testing mechanism 6, a display screen 7 fixedly mounted on the testing mechanism 6, a button 8 fixedly mounted at the bottom of the display screen 7, a cavity 2 opened inside the fixed box 1, a fixed plate 17 fixed inside the cavity 2, a winch 19 rotatably mounted between the fixed plates 17, a drive motor 18 fixedly mounted on one side of the fixed plate 17, a cable 12 wound around the winch 19, a support tube 13 movably mounted on the cable 12, a probe 14 movably mounted inside the support tube 13, the probe 14 fixedly mounted at one end of the cable 12, the cable 12 driving the probe 14 to move and compress a ring seat 23, the compression and movement of the ring seat 23 providing the necessary space for the probe 14 to be stored.

[0023] In this embodiment, a baffle 20 is welded to the inner wall of the cavity 2, and a movable plate 3 is movably installed on the top of the baffle 20. A partition plate 4 is fixed on the movable plate 3. An opening is opened on the side of the fixed box 1, and the cable 12 is movably installed inside the opening. A support base 9 is movably installed on the side of the fixed box 1, and a fixing groove 10 is opened on the support base 9. A fixing block 11 is movably installed inside the fixing groove 10. A limit bolt 16 is rotatably installed on the fixing block 11. After the fixing block 11 moves in the fixing groove 10, the limit bolt 16 rotates to complete the position limit and fixation of the fixing block 11, which facilitates the fixed-point descent movement of the cable 12.

[0024] In this embodiment, the support base 9 has a limiting groove 15 on its side, and the limiting bolt 16 is movably installed inside the limiting groove 15. A fixing tube 21 is fixed on one side of the fixing block 11. A ring seat 23 is movably installed inside the support tube 13. The ring seat 23 is installed inside the support tube 13 through a support mechanism 24. The ring seat 23 is movably engaged with the probe 14. An installation groove is opened inside the fixing tube 21. A roller 22 is rotatably installed inside the installation groove. The roller 22 is in movable contact with the cable 12. The support mechanism 24 is a support spring. The support spring pushes the ring seat 23 to move downward. The downward movement of the ring seat 23 pushes the probe 14 out for testing.

[0025] When the device is in use, the drive motor 18 is started and reversed to rotate the winch 19. The rotation of the winch 19 loosens and pulls out the cable 12. After the support base 9 loses the tension of the cable 12, the support base 9 moves the support tube 13 to the required installation position. The support base 9 is placed at the drilling position and provides support for the probe 14. Before the probe 14 is placed, the fixing block 11 slides inside the fixing groove 10. The sliding of the fixing block 11 adjusts the position of the support tube 13 as it descends. After the fixing block 11 is adjusted, the limiting bolt 16 is rotated. One end of the limiting bolt 16 contacts the outer wall of the support base 9 for fixation, thus completing the limitation of the fixing block 11. When the probe 14 is lowered, the cable 12 descends together with the support tube 13. The cable 12 contacts the roller 22 during descent and moves on the roller 22. The roller 22 reduces the friction between the cable 12 and the fixing tube 21. When the probe 14 descends and encounters... After encountering resistance, the resistance point pushes the probe 14 upward, and the upward movement of the probe 14 compresses the ring seat 23. Under the compression, the ring seat 23 retracts and moves through the support mechanism 24, and the probe 14 enters the interior of the support tube 13 for buffer protection. When the cable 12 can no longer descend, the cable 12 is pulled upward a certain distance, so that the obstacle point loses its compression on the probe 14. Under the push of the ring seat 23, the probe 14 is exposed downward for testing. When it is necessary to move the fixed box 1 a short distance, the drive motor 18 is started to drive the winch 19 to rotate. The winch 19 winds the cable 12. As the cable 12 winds, the support seat 9 contacts the outer wall of the fixed box 1. One end of the support tube 13 contacts the support seat 9 and is limited. Under the continuous tension of the cable 12, the probe 14 is compressed and retracted into the support tube 13 by the ring seat 23. Thus, the probe 14 can be shielded and protected without disassembling it during short-distance movement.
