Description
Technical Field
[0001] This utility model relates to the technical field of aperture detection auxiliary devices, and more specifically, to an aperture detection auxiliary device for a hole forming quality detector. Background Technology
[0002] In the construction of bored piles and trenches in building and transportation engineering, trench quality monitoring is a key link to ensure project safety. For example, Chinese Patent Publication No. CN221744896U discloses a hole diameter detection auxiliary device for a hole quality testing instrument, specifically involving the field of hole diameter detection auxiliary devices. Through innovative design, it improves the detection accuracy: its structure includes a universal connector, a guide rail measuring component, measuring legs, and rollers. In this solution, one end of the measuring leg is hinged to the universal connector, the side is linked with the guide rail component, and the end roller can move along the hole wall. By measuring the displacement of the guide rod in the track, the unfolding angle of the measuring leg can be calculated, thereby obtaining hole diameter change data in different directions.
[0003] However, the device has two major drawbacks in practical applications: First, rainwater and groundwater often seep into the slots, causing water accumulation and damage to the measuring elements; second, the slots are mostly cylindrical, and it is difficult to fully cover the inner wall by simply moving the rollers up and down in a straight line. Manual operation is required to rotate the equipment synchronously, which is complex and prone to data loss. Therefore, this application proposes an auxiliary device for hole diameter detection in a hole forming quality tester, which aims to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an auxiliary device for pore diameter detection in a hole forming quality testing instrument, so as to solve the problems mentioned in the background art above:
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An auxiliary device for hole diameter detection in a hole forming quality detector includes a clamping frame. A clamping bolt is movably installed on one side of the clamping frame, and a telescopic tube is movably installed on the other side of the clamping frame. A lead screw is threaded into the telescopic tube. The lead screw is movably connected to a limiting plate. A measuring tube is movably connected to the lower end of the lead screw. A measuring slide rod is movably installed inside the measuring tube.
[0007] A measuring plate is fixedly connected to the telescopic tube, and a slider is slidably connected inside the measuring plate. A movable tube is fixedly connected below the slider, and a movable rod is movably installed inside the movable tube. The lower end of the movable rod passes through the measuring tube and is fixedly connected to the measuring slide rod.
[0008] By adopting the above technical solution, the clamping frame is fixed above the slot. Rotating the handle causes the telescopic tube to rotate, thereby extending the lead screw downwards. The slider at one end of the measuring slide slides on the inner wall of the slot. The rotation of the telescopic tube simultaneously drives the measuring plate, movable tube, movable rod, measuring tube, and other structures to rotate, ultimately causing the measuring slide to rotate. This causes the measuring slide to rotate and move upwards on the inner wall of the slot, resulting in more comprehensive detection data and more convenient operation.
[0009] Preferably, one end of the clamping bolt is fixedly connected to a clamping plate, and the clamping plate is located inside the clamping frame.
[0010] By adopting the above technical solution, the contact area of the clamping plate is increased, which makes the structure of the clamping frame and the slotted accessory fixed.
[0011] Preferably, the telescopic tube is rotatably connected to the clamping frame via an upper bearing, and a limiting groove is provided inside the lead screw, with the limiting plate movably installed in the limiting groove.
[0012] By adopting the above technical solution, the limiting plate prevents the lead screw from rotating synchronously with the telescopic tube.
[0013] Preferably, an adjusting frame is fixedly connected to the clamping frame, and a handle is provided on the adjusting frame. The handle is rotatably connected to the adjusting frame via a drive bearing. A drive gear is fixedly connected to the lower end of the handle, and a driven gear is fixedly connected to the telescopic tube. The drive gear and the driven gear mesh with each other.
[0014] By adopting the above technical solution, the handle can be easily rotated by operating the telescopic tube through the driven gear and the driving gear.
[0015] Preferably, the lower end of the lead screw is rotatably connected to the measuring tube via a lower bearing. The measuring tube has a movable groove, and the movable rod passes through the movable groove and is fixedly connected to the measuring slide rod. A spring is movably installed inside the measuring tube at a position located on the side of the measuring slide rod.
[0016] By adopting the above technical solution, the measuring slide rod is pushed downward by the spring, giving the movable rod, movable tube and slider the ability to move to the side, so that the sliding head set at one end of the measuring slide rod can slide along the inner wall.
[0017] Preferably, the measuring plate has grooves on both sides, the slider is slidably connected to the grooves, pointers are fixedly connected to both sides of the slider, and the measuring plate has scales corresponding to the pointers on both sides.
[0018] By adopting the above technical solution, the pointer moves synchronously with the slider, and the measurement is set with scales to clearly display the distance the pointer moves.
[0019] Preferably, the upper end of the movable rod is fixedly connected to a sliding column, which is slidably connected inside the movable tube.
[0020] By adopting the above technical solution, the sliding column is used to prevent the movable rod and movable tube from detaching from each other.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1) This aperture detection auxiliary device rotates the telescopic tube, making it easier for the lead screw to move downwards, driving the measuring slide rod to move linearly up and down on the inner wall of the aperture groove, measuring the aperture inner wall in the vertical direction.
[0023] 2) In this aperture detection auxiliary device, when the telescopic tube rotates, the measuring plate, movable rod and other structures rotate synchronously, which drives the measuring slide rod to rotate synchronously. This allows the measuring slide rod to rotate synchronously during the linear lifting and lowering process, thereby moving circumferentially along the inner wall of the aperture groove, resulting in more comprehensive measurement data.
[0024] 3) This aperture detection auxiliary device only requires rotating the handle to operate the measuring slide rod to move linearly and circumferentially, making operation more convenient. Attached Figure Description

[0032] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 An auxiliary device for hole diameter detection in a hole forming quality detector includes a clamping frame 1. A clamping bolt 3 is movably installed on one side of the clamping frame 1 and is threadedly connected to the clamping frame 1. A telescopic tube 4 is movably installed on the other side of the clamping frame 1. A lead screw 6 is threadedly connected to the telescopic tube 4. The inner wall of the telescopic tube 4 is engraved with threads. The lead screw 6 is movably connected to a limiting plate 7 and is slidably connected to the lead screw 6. A measuring tube 11 is movably connected to the lower end of the lead screw 6. A measuring slide rod 13 is movably installed inside the measuring tube 11 and a slide head is provided at one end of the measuring slide rod 13.
[0033] One end of the clamping bolt 3 is fixedly connected to the clamping plate 2, which is located inside the clamping frame 1. The clamping plate 2 increases the contact area and improves the stability of the clamping frame 1. The telescopic tube 4 is rotatably connected to the clamping frame 1 through the upper bearing 5, so that the telescopic tube 4 can easily rotate on the lead screw 6. The lead screw 6 has a limiting groove 8, and the limiting plate 7 is movably installed in the limiting groove 8. The upper end of the limiting plate 7 is fixedly connected to the adjusting frame 22.
[0034] An adjusting frame 22 is fixedly connected to the clamping frame 1. A handle 24 is provided on the adjusting frame 22. The handle 24 is rotatably connected to the adjusting frame 22 through a drive bearing 25. The handle 24 facilitates the operation of the drive gear 23 for rotation. The lower end of the handle 24 is fixedly connected to the drive gear 23. A driven gear 9 is fixedly connected to the telescopic tube 4. The drive gear 23 and the driven gear 9 mesh with each other, and the driven gear 9 and the drive gear 23 drive each other.
[0035] The steps of using this utility model are as follows: In this aperture detection auxiliary device, the handle 24 is rotated, which causes the drive gear 23 to rotate and drive the driven gear 9 to rotate. The driven gear 9 drives the telescopic tube 4 to rotate. The lead screw 6 inside the telescopic tube 4 is restricted by the limiting plate 7 and cannot rotate synchronously. It can only move linearly along the direction of the limiting plate 7. When the telescopic tube 4 rotates, the lead screw 6 extends outward, causing the two measuring slide rods 13 below the lead screw 6 to move linearly on the inner wall of the hole groove, thereby measuring the linear position data on the inner wall.
[0036] Example 2, please refer to Figures 1 to 5The difference from the basic embodiment 1 is that a measuring plate 20 is fixedly connected to the telescopic tube 4. The measuring plate 20 rotates synchronously with the telescopic tube 4. A slider 18 is slidably connected inside the measuring plate 20. The slider 18 maintains a relative position with the measuring slide rod 13 through structures such as the movable tube 15 and the movable rod 16. When the measuring slide rod 13 moves, the slider 18 moves synchronously. The movable tube 15 is fixedly connected to the lower position of the slider 18. The movable rod 16 is movably installed inside the movable tube 15. The lower end of the movable rod 16 passes through the measuring tube 11 and is fixedly connected to the measuring slide rod 13, so that the movable rod 16 drives the measuring slide rod 13 to move synchronously.
[0037] The lower end of the lead screw 6 is rotatably connected to the measuring tube 11 via the lower bearing 10, making the measuring tube 11 easy to rotate. The measuring tube 11 has a movable groove 12, and the movable rod 16 passes through the movable groove 12 and is fixedly connected to the measuring slide rod 13, making it easy for the movable rod 16 to move laterally along the movable groove 12. A spring 14 is movably installed inside the measuring tube 11 at the side position of the measuring slide rod 13. Through the structure of the spring 14, the measuring slide rod 13, the movable rod 16, the movable tube 15 and the slider 18 are pushed to the side.
[0038] The measuring plate 20 has grooves 21 on both sides, and the slider 18 is slidably connected to the grooves 21. The slider 18 moves linearly along the grooves 21. The two sides of the slider 18 are fixedly connected to pointers 19. The measuring plate 20 has scales on both sides corresponding to the pointers 19, which make it easy to show whether the pointers 19 have moved.
[0039] The upper end of the movable rod 16 is fixedly connected to a sliding column 17, which is slidably connected inside the movable tube 15. The diameter of the through hole at the lower end of the movable tube 15 is smaller than that of the sliding column 17, so that the movable rod 16 is not easily detached from the movable tube 15.
[0040] The steps of using this utility model are as follows: In this aperture detection auxiliary device, the spring 14 pushes the measuring slide rod 13 outward in the measuring tube 11, causing the measuring slide rod 13 to slide against the inner wall of the aperture groove. The measuring slide rod 13 maintains a relative position with the slider 18 through the movable rod 16, movable tube 15, and other structures. The two sliders 18 slide in the grooves 21 on both sides of the measuring plate 20. The position of the slider 18 is displayed by the scale on the side of the measuring plate 20. When the telescopic tube 4 rotates, the measuring plate 20, movable tube 15, and movable rod 16 move together. The step rotation causes the measuring slide rod 13 and measuring tube 11 to rotate through the lower bearing 10, so that the measuring slide rod 13 moves in a straight line and also moves in a circle along the inner wall of the groove, thus collecting data more comprehensively. When the pointer 19 of the slider 18 moves, it indicates that there is a problem with the structure and size of the inner wall of the groove. When the pointer 19 does not change position, it indicates that the inner wall of the groove is smooth, thus more comprehensively detecting the inner wall of the groove. Moreover, this auxiliary device is a purely mechanical structure, and water accumulation has no effect on it, improving its applicability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
