Description

Technical Field

[0001] This utility model relates to the field of combined support technology, and in particular to a combined auxiliary support device for anchor bolt and anchor cable testing. Background Technology

[0002] In engineering fields such as mining, tunnel construction, and slope reinforcement, anchor bolts and cables are key components for ensuring the stability of geotechnical engineering, and their anchoring quality directly affects project safety. To accurately detect parameters such as pull-out force and stress distribution of anchor bolts and cables, a combined auxiliary support device for anchor bolt and cable testing has been developed.

[0003] Currently, most existing anchor bolt and cable testing auxiliary supports employ fixed mechanical structures. Their technical principle primarily involves assembling the various components of the support into a single frame through welding or bolting. The height, angle, and other parameters of this frame are determined during manufacturing. In use, it is placed at the testing point and simply fixed to the ground or rock face with bolts, thus supporting the testing equipment. During testing, the rigid structure of the support provides a stable load-bearing platform for the testing equipment, thereby completing the relevant testing work for anchor bolts and cables.

[0004] However, existing fixed anchor bolt and cable testing auxiliary supports have significant problems. Due to their simple structure, their height, angle, and other parameters cannot be flexibly adjusted according to the actual terrain or the installation angle of the anchor bolts and cables. In complex geological environments, such as undulating tunnels and slopes with varying inclination angles, fixed supports are difficult to adapt to the anchor bolts and cables, and are prone to swaying or even tilting. This not only affects the stability of the testing equipment but also leads to large errors in the testing data, severely reducing the reliability of the test results and failing to meet the engineering requirements for accurate anchor bolt and cable testing. Therefore, a combined auxiliary support device for anchor bolt and cable testing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a combined auxiliary support device for anchor bolt and anchor cable testing, which aims to improve the problem that the existing support structure is simple, cannot be flexibly adjusted according to the terrain or anchor bolt angle, and is prone to swaying in complex geological environments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A combined auxiliary support device for anchor bolt and anchor cable testing includes a base, a connecting rod rotatably connected to the side wall of the base, a sleeve rod slidably connected to the outer wall of the connecting rod, a rotating component at one end of the sleeve rod, and a locking component at one end of the connecting rod.

[0008] The clamping assembly includes a connecting block, the side wall of which is fixedly connected to the inside of the connecting rod, a spring plate fixedly connected to the top of the connecting block, a second spring provided on the side wall of the spring plate, both ends of the second spring being fixedly connected to the side wall of the spring plate, and a locking ball fixedly connected to the side wall of the spring plate, the outer wall of the locking ball being disposed inside the sleeve rod.

[0009] As a further description of the above technical solution:

[0010] The rotating assembly includes a universal ball joint, one end of which is fixedly connected to one end of a sleeve rod. A sleeve is provided on the outer wall of the universal ball joint, a locking assembly is provided on the outer wall of the sleeve, and a support assembly is provided at one end of the sleeve.

[0011] As a further description of the above technical solution:

[0012] The locking assembly includes a bolt, the outer wall of which is threaded into the inside of the sleeve, and one end of the bolt is located on the outer wall of the universal ball.

[0013] As a further description of the above technical solution:

[0014] The support assembly includes a chassis, the bottom of which is fixedly connected to one end of a sleeve, and a base plate is fixedly connected to the inner wall of the chassis.

[0015] As a further description of the above technical solution:

[0016] A hollow block is fixedly connected to the top of the base plate, a limit ring is fixedly connected inside the hollow block, and a sliding column is slidably connected inside the limit ring.

[0017] As a further description of the above technical solution:

[0018] A soft block is fixedly connected to one end of the sliding column, the outer wall of the sliding column is slidably connected to the inside of the hollow block, and a locking post is fixedly connected to the outer wall of the sliding column.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the locking post is slidably connected to the inside of the hollow block. One end of the sliding post is fixedly connected to a connecting plate. A first spring is provided on the side wall of the connecting plate, and both ends of the first spring are fixedly connected to the side wall of the connecting plate.

[0021] As a further description of the above technical solution:

[0022] The hollow block has a connecting plate slidably connected to its outer wall, and a hollow plate is fixedly connected to the side wall of the connecting plate. The outer wall of the locking post is located inside the connecting plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the connecting rod slides on the inner wall of the sleeve rod, and then drives the locking ball to lock it inside the sleeve rod, thereby moving the elastic plate on the side wall and causing the second spring to contract, achieving the effect of a combined support. This solves the problem of the support structure being too simple, unable to be flexibly adjusted according to the terrain or anchor angle, and prone to shaking in complex geological environments, thus improving the convenience of the combined auxiliary support device for testing.

[0025] 2. In this utility model, pressing the soft block drives the sliding column to move, which in turn drives the outer wall's locking column to move. Next, the locking column is disengaged from the inside of the connecting plate, achieving the effect of quick-release testing device. This solves the problem that traditional brackets need to be disassembled piece by piece using bolts, buckles, and other fixing components, which takes a long time to assemble or disassemble before and after a single test, significantly extending the overall testing cycle. This improves the practicality of the combined auxiliary bracket device for testing. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4 The present invention provides an embodiment of a combined auxiliary support device for anchor bolt and anchor cable testing, comprising a base 1, a connecting rod 2 rotatably connected to the side wall of the base 1, the connecting rod 2 being slidably nested inside a sleeve rod 3, and the length of the support can be freely extended and retracted by adjusting the relative position of the two to adapt to the anchor bolt and anchor cable testing needs of different heights, and to improve the applicability of the device in narrow or complex spaces. The outer wall of the connecting rod 2 is slidably connected to the sleeve rod 3, one end of the sleeve rod 3 is provided with a rotating component, and one end of the connecting rod 2 is provided with a locking component.

[0035] The clamping assembly includes a connecting block 16, the side wall of which is fixedly connected to the inside of the connecting rod 2. A spring plate 17 is fixedly connected to the top of the connecting block 16. The spring plate 17, the first spring 15, and the second spring 19 are made of 65Mn spring steel and are used to provide elastic restoring force. This is existing technology and will not be described in detail here. The side wall of the spring plate 17 is provided with a second spring 19, both ends of which are fixedly connected to the side wall of the spring plate 17. A locking ball 18 is fixedly connected to the side wall of the spring plate 17. The locking ball 18, through the elastic restoring function of the spring plate 17 and the second spring 19, forms a locking engagement with the inner wall of the sleeve rod 3. After telescopic adjustment, the relative position of the connecting rod 2 and the sleeve rod 3 is automatically fixed to prevent the bracket from accidentally slipping off during the testing process. The outer wall of the locking ball 18 is located inside the sleeve rod 3.

[0036] Reference Figure 1 and Figure 5The support assembly includes a chassis 4, with its bottom fixedly connected to one end of a sleeve 6. A base plate 13 is fixedly connected to the inner wall of the chassis 4, and a hollow block 9 is fixedly connected to the top of the base plate 13. A limit ring 21 is fixedly connected inside the hollow block 9, and a sliding post 10 is slidably connected inside the limit ring 21. A soft pad 11 is fixedly connected to one end of the sliding post 10. Pressing the soft pad 11 drives the sliding post 10, causing the locking post 12 to disengage from the connecting plate 7, thus releasing the hollow block 9 from the connecting plate 7. This enables quick disassembly and replacement of the detection device, reducing [the risk of damage / reduction]. To reduce downtime and improve testing efficiency, the outer wall of the sliding column 10 is slidably connected to the inside of the hollow block 9. A locking column 12 is fixedly connected to the outer wall of the sliding column 10. The outer wall of the locking column 12 is slidably connected to the inside of the hollow block 9. A connecting plate 14 is fixedly connected to one end of the sliding column 10. A first spring 15 is provided on the side wall of the connecting plate 14. Both ends of the first spring 15 are fixedly connected to the side wall of the connecting plate 14. A connecting plate 7 is slidably connected to the outer wall of the hollow block 9. A hollow plate 8 is fixedly connected to the side wall of the connecting plate 7. The outer wall of the locking column 12 is located inside the connecting plate 7.

[0037] Reference Figures 1-3 The rotating assembly includes a universal ball 5, one end of which is fixedly connected to one end of the sleeve rod 3. A sleeve 6 is provided on the outer wall of the universal ball 5, and a locking assembly is provided on the outer wall of the sleeve 6. A support assembly is provided at one end of the sleeve 6. The locking assembly includes a bolt 20. The bolt 20 is made of 8.8 grade high-strength carbon steel to meet the locking force requirements. This is existing technology and will not be described in detail here. The outer wall of the bolt 20 is threaded into the inside of the sleeve 6. One end of the bolt 20 is located on the outer wall of the universal ball 5. The spherical surface of the universal ball 5 and the sleeve 6 are engaged, allowing the sleeve rod 3 to rotate at multiple angles. This supports the bracket device to be flexibly adjusted in the horizontal, vertical, or inclined directions, ensuring the accurate alignment of the testing equipment with the anchor rod and anchor cable. The bolt 20 is screwed into the sleeve 6 through the thread and presses against the outer wall of the universal ball 5, quickly locking the rotation angle of the sleeve rod 3 and preventing angle deviation caused by external force interference during the testing process.

[0038] Working principle: When using the combined auxiliary support device for anchor bolt and anchor cable testing, firstly, the connecting rod 2 is slid into the inside of the sleeve rod 3. Then, when the connecting rod 2 moves, the connecting block 16 is driven to slide into the inside of the sleeve rod 3. Then, when the connecting block 16 moves, the locking ball 18 will press against the inside of the sleeve rod 3. At the same time, after the locking ball 18 is subjected to force, it will drive the elastic plate 17 on the side wall to move. Next, the second spring 19 will contract, and then the locking ball 18 will be reset to its original position, pressing against the inside of the sleeve rod 3, thus achieving the effect of the combined support.

[0039] Next, when quickly disassembling the testing device, first press the soft block 11. The soft block 11, under force, will drive the sliding column 10 on the side wall to slide inside the hollow block 9. Then, the sliding column 10 slides inside the limiting ring 21, limiting the sliding column 10. At the same time, when the sliding column 10 moves, it will drive the connecting plate 14 on the side wall to slide inside the hollow block 9. Then, the connecting plate 14, under force, will drive the first spring 15 on the side wall to retract. At the same time, the retraction of the first spring 15 will reset the position of the locking column 12. In summary, when the sliding column 10 moves, it will drive the locking column 12 on the outer wall to move. Next, the outer wall of the locking column 12 will be disengaged from the inside of the connecting plate 7, and the inner wall of the connecting plate 7 can be disengaged from the outer wall of the hollow block 9, achieving the effect of quick disassembly of the testing device.

[0040] At the same time, the lever 3 can be moved. The force on the lever 3 will drive the universal ball 5 at one end to rotate inside the sleeve 6. The lever 3 can be moved at multiple angles through the universal ball 5 and the sleeve 6. At the same time, the bolt 20 can be rotated. The bolt 20 rotates inside the sleeve 6, and one end of the bolt 20 can be pressed against the outer wall of the universal ball 5 to lock the angle of the lever 3.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
