Description

Technical Field

[0001] This utility model relates to the technical field of top anchor torque testing tools, and in particular to a special tool for testing top anchor torque force. Background Technology

[0002] In order to ensure the quality of anchor bolt installation during the tunneling process, it is necessary to test the torque force of the anchor bolts. When testing the top anchor bolts, it is often necessary to stand on a ladder. On the one hand, it is inconvenient for the testing personnel to operate while standing on the ladder, and on the other hand, working at height poses safety hazards. When using top anchor torque testing tools, most traditional testing devices are fixed structures. The support height of these devices is preset and cannot be changed. Their design is often intended for testing top anchors in roadways at a specific height. In terms of construction, they usually adopt an integrated rigid structure with fixed relative positions between components and lack height adjustment modules. For example, a common traditional testing device may consist of a fixed-length support rod and an upper testing mechanism. The support rod is in direct contact with the ground and cannot be extended, retracted, or adjusted.

[0003] Therefore, to address the issue of inconvenience in adapting to the testing needs of top anchors at different heights in roadway testing scenarios, a dedicated tool for testing top anchor torque can be designed. When using this tool, during height adjustment, the locking mechanism is squeezed inwards. This mechanism causes the locking rod to disengage from the locking hole inside the guide column. At this time, the upper sleeve can slide along the inner wall of the lower sleeve, while the guide column moves synchronously with the sliding ring, achieving the extension and retraction adjustment of the support rod. After adjustment to the desired height, the locking rod aligns with another set of locking holes. Releasing the locking mechanism drives the locking rod to reset, and the locking rod re-inserts into the corresponding locking hole to complete height locking. During testing, the anchor rod agitator is fitted onto the bottom of the anchor rod to be tested. By using a wrench to remove the fixing nut at the bottom of the sleeve and applying torque, the torque force of the anchor rod can be detected. This tool, through the coordinated design of the guide mechanism and the locking mechanism, achieves precise extension and retraction adjustment and reliable locking of the support rod, adapting to the testing needs of top anchors in roadways at different heights and improving testing efficiency.

[0012] The beneficial effects of this utility model are: 1. When using this top anchor torque testing tool, during height adjustment, squeeze the locking mechanism inward. The locking mechanism causes the locking rod to disengage from the locking hole inside the guide column. At this time, the upper sleeve can slide along the inner wall of the lower sleeve, and the guide column moves synchronously with the sliding ring to achieve the extension and retraction adjustment of the support rod. When adjusted to the required height, the locking rod aligns with another set of locking holes. Releasing the locking mechanism drives the locking rod to reset, and the locking rod re-inserts into the corresponding locking hole to complete the height locking. During testing, the anchor rod agitator is fitted onto the bottom of the anchor rod to be tested. The fixing nut at the bottom of the sleeve is removed by using a wrench, and torque is applied to detect the torque force of the anchor rod. This tool, through the coordinated design of the guide mechanism and the locking mechanism, achieves precise extension and retraction adjustment and reliable locking of the support rod, and can adapt to the testing needs of top anchors in roadways of different heights, improving testing efficiency.

[0013] 2. Firstly, by sliding the support rod and the lower sleeve, traditional high-altitude operations are transformed into ground operations.

The lower sleeve 4 is slidably sleeved on the outer wall of the lower end of the support rod 1, a fixing nut 5 is fixedly installed at the lower end of the lower sleeve 4, a fixing ring 6 is fixedly installed at the lower end of the upper sleeve 3 and the upper end of the lower sleeve 4, a sliding ring 7 is slidably sleeved on the outer wall of the lower sleeve 4, a guide post 8 is fixedly installed between the sliding ring 7 and the upper fixing ring 6, a locking mechanism is provided inside the lower fixing ring 6, each locking mechanism is provided with a locking rod 9, and multiple locking holes 10 are opened through the inner wall of each guide post 8, with the locking rod 9 embedded inside the locking holes 10.

[0017] Please see Figure 2 and Figure 3 The bottom of the anchor bolt mixer 2 is fixedly connected to the upper end of the support rod 1. A guide plate 11 is fixedly installed between the sliding ring 7 and the upper fixed ring 6. Both sets of guide columns 8 and guide plates 11 slide through the interior of the lower fixed ring 6. The upper sleeve 3 can slide along the inner wall of the lower sleeve 4. At the same time, the guide columns 8 and guide plates 11 move synchronously with the sliding ring 7 to realize the extension and retraction adjustment of the support rod 1.

[0018] Please see Figure 3 and Figure 4The locking mechanism includes a guide groove 12, a guide rod 13, an adjusting plate 14, and a return spring 15. Two sets of guide grooves 12 are opened through the lower fixing ring 6. A guide rod 13 is fixedly installed inside each set of guide grooves 12. An adjusting plate 14 is slidably sleeved on the side wall of each set of guide rods 13. A return spring 15 is fixedly installed between the upper side wall of each set of adjusting plates 14 and the inner wall of the corresponding guide groove 12. When the two sets of adjusting plates 14 are squeezed inward, the adjusting plates 14 compress the return spring 15. At this time, the upper sleeve 3 can slide along the inner wall of the lower sleeve 4. The locking rod 9 is fixedly installed on the lower side wall of the adjusting plate 14. One end of the return spring 15 is fixedly connected to the upper side wall of the adjusting plate 14, and the other end is fixedly connected to the inner wall of the guide groove 12.

[0019] When the top anchor torque testing tool is used, the working principle of this utility model top anchor torque force testing tool is as follows: When adjusting the height, pinch the two sets of adjusting plates 14 of the locking mechanism inward. The adjusting plates 14 compress the return spring 15 and drive the locking rod 9 to disengage from the locking hole 10 inside the guide column 8. At this time, the upper sleeve 3 can slide along the inner wall of the lower sleeve 4. At the same time, the guide column 8 and the guide plate 11 move synchronously with the sliding ring 7 to realize the extension and retraction adjustment of the support rod 1. When the desired height is reached, the locking rod 9 is aligned with another set of locking holes 10. Release the adjusting plate 14, the return spring 15 drives the adjusting plate 14 to reset, and the locking rod 9 is reinserted into the corresponding locking hole 10 to complete the height locking.

[0020] During testing, the anchor bolt mixer 2 is fitted onto the bottom of the anchor bolt to be tested. The fixing nut 5 at the bottom of the sleeve 4 is removed by using a wrench and torque is applied to detect the torque force of the anchor bolt. The entire process achieves height self-adjustment through mechanical structure, avoiding the risk of high-altitude operation for workers.

[0021] The beneficial effects of this tool are mainly reflected in the following aspects: First, through the coordinated design of the guiding mechanism and the locking mechanism, the support rod 1 can be precisely extended and reliably locked, which can adapt to the testing needs of top anchors in roadways of different heights and improve testing efficiency.

In use, first connect the threaded hole 16 at the bottom of the anchor mixer 2 to the threaded head 17 at the top of the support rod 1. At this point, the transverse threaded holes 18 of both are aligned. Insert the fastening bolt 19 and tighten the fastening nut 20 to securely install the anchor mixer 2. Disassembly is performed by reversing the operation. The dual fixing method of threaded connection and fastening bolt 19 ensures a stable connection between the anchor mixer 2 and the support rod 1, preventing components from loosening during testing. The modular design allows for quick assembly and disassembly of the anchor mixer 2, facilitating tool maintenance and component replacement, and reducing operating costs.

[0024] Through the above steps, when the top anchor torque testing tool is in use, during height adjustment, the locking mechanism is squeezed inward. The locking mechanism drives the locking rod 9 to disengage from the locking hole 10 inside the guide column 8. At this time, the upper sleeve 3 can slide along the inner wall of the lower sleeve 4, and the guide column 8 moves synchronously with the sliding ring 7 to realize the extension and retraction adjustment of the support rod 1. When the desired height is reached, the locking rod 9 is aligned with another set of locking holes 10. The locking mechanism is released to drive the locking rod 9 to reset, and the locking rod 9 is reinserted into the corresponding locking hole 10 to complete the height locking. During testing, the anchor rod agitator 2 is sleeved on the bottom of the anchor rod to be tested. The fixing nut 5 at the bottom of the sleeve 4 is removed by wrench and torque is applied to detect the torque force of the anchor rod. Through the coordinated design of the guide mechanism and the locking mechanism, this tool realizes the precise extension and retraction adjustment and reliable locking of the support rod 1, which can be adapted to the testing needs of top anchors in roadways of different heights and improve testing efficiency.
