Description

Technical Field

[0001] The invention relates to the technical field of axial force meters, and more specifically to a groutable hollow fan-shaped self-anchored anchor rod axial force meter. Background Art

[0002] Anchor rods are the most basic component of tunnel support in contemporary coal mines. In the fields of underground engineering and slope engineering, anchor support is the most widely used reinforcement technology. Due to the different characteristics of the rock masses at different depths around the tunnels and the different stress environments, uncoordinated deformation is prone to occur. Therefore, when using anchor rods, nuts are needed to pre-tighten the anchor rods to prevent the nuts from loosening due to deformation of the surrounding rock, which may lead to support failure.

[0003] A Chinese patent with authorization publication number CN110631744B discloses an anchor dynamometer for monitoring the axial force of an anchor rod. A plurality of anchor limit sleeves are arranged to avoid the error caused by the operation of a single anchor limit sleeve, and the limit nut and the adjusting screw cooperate to fix the position of the upper support arm and the lower support arm, thereby achieving the sealing of the upper arc limit plate and the lower arc limit plate, ensuring the accuracy of the force measuring assembly and avoiding interference of the force measuring assembly by the external environment.

[0004] Although the anchor dynamometer used to monitor the axial force of the anchor bolt realizes the sealing of the upper arc limit plate and the lower arc limit plate, ensures the accuracy of the force measuring assembly, and avoids the interference of the force measuring assembly by the external environment, it needs to be welded and installed during actual use. As for the welding process, not only the welding process requirements are high, but also the welding equipment needs to be carried to the construction site, which increases the complexity and cost of the construction.

There are problems such as complex installation, affected measurement accuracy, many safety hazards, high cost, poor environmental adaptability and insufficient long-term reliability. Therefore, it is necessary to adopt a non-welding installation method to improve the installation efficiency, measurement accuracy and long-term reliability of the axial force gauge.

[0032] See also Figures 1 to 8 A groutable hollow fan-shaped self-anchored anchor axial force meter, comprising an anchor active head 1, a steel plate 2 is fixedly mounted on the upper end of the anchor active head 1, an axial force meter body 3 is arranged on the upper side of the steel plate 2, a fixing mechanism 1 is arranged on the outer side of the axial force meter body 3, a fixing mechanism 2 is arranged inside the fixing mechanism 1, and a fixing mechanism 3 is arranged inside the fixing mechanism 2;

[0033] The fixing mechanism 1 includes a plurality of groups of slide grooves 4 provided on the outer surface of the axial force meter body 3, a slider 5 is slidably connected inside the slide groove 4, a transmission ring 6 is sleeved on the outer side of the axial force meter body 3, and the plurality of sliders 5 are fixedly connected to the transmission ring 6, a telescopic rod 7 is provided inside one group of slide grooves 4, and the telescopic rod 7 is fixedly installed between the slider 5 and the inner wall of the slide groove 4, a fixing ring 8 is provided on the lower side of the transmission ring 6, and a plurality of groups of fixing parts 9 are fixedly installed between the fixing ring 8 and the axial force meter body 3, and a pair of fixing mechanisms are provided between the axial force meter body 3 and the steel plate 2. The transmission ring 6 is preliminarily fixed, the outer surface of the transmission ring 6 is sleeved with a ring sleeve 10, the outer surface of the ring sleeve 10 is rotatably connected with a connecting rod 11, the outer surface of the fixing ring 8 is sleeved with a ring sleeve 2 12, the outer surface of the ring sleeve 2 12 is rotatably connected with a connecting rod 2 13, a support column 14 is fixedly installed at the corner of the upper end surface of the steel plate 2, a slot 17 is provided on the side end surface of the support column 14, a plug rod 16 is inserted into the inside of the slot 17, one end of the plug rod 16 is rotatably connected with a connecting piece 15, and the connecting rod 11 and the connecting rod 2 13 are both rotatably connected to the connecting piece 15.

[0034] The existing axial force meter main body 3 needs to be welded and installed during actual use. However, the welding process not only requires high welding process requirements but also requires carrying welding equipment to the construction site, which increases the complexity and cost of the construction. At the same time, the welding process is time-consuming. Especially for large-scale pipe-penetrating projects, welding installation will significantly extend the construction period. There are problems such as complex installation, affected measurement accuracy, many safety hazards, high cost, poor environmental adaptability and insufficient long-term reliability. Therefore, it is necessary to adopt a non-welding installation method to improve the installation efficiency, measurement accuracy and long-term use reliability of the axial force meter. Therefore, this scheme can achieve the initial and quick installation of the axial force meter by setting a fixing mechanism 1, which greatly simplifies the on-site operation process and improves the installation efficiency. It also reduces the dependence on professional tools, making the construction more convenient and efficient. Specifically: when the axial force meter body 3 needs to be installed on the steel plate 2 on the anchor rod flexible head 1, first put the clamping ring of the axial force meter body 3 into the clamping groove on the steel plate 2, and then start the telescopic rod 7, so that the telescopic rod 7 drives the slider 5 to slide down inside the slide groove 4, and the slider 5 will synchronously carry the transmission ring 6 to slide down synchronously, and the transmission ring 6 will synchronously carry the ring sleeve 10 to slide down, and the ring sleeve 10 will carry the connecting rod 11 to descend, and the connecting rod 2 13 on the ring sleeve 2 12 is synchronously connected with the connecting rod 11 with the connecting piece 15 on the plug rod 16. Therefore, the plug rod 16 will move to the slot 17 on the support column 14 and be inserted into the inside of the slot 17 to perform a preliminary fixed installation on the axial force meter body 3.

[0035] The second fixing mechanism includes a cross bar 18 fixedly installed on the outer surface of the transmission ring 6, a vertical bar 19 fixedly installed on one end of the cross bar 18, a transmission frame 23 fixedly installed on the lower end of the vertical bar 19, a ring sleeve 3 20 is provided on the outer surface of the fixing ring 8 corresponding to the cross bar 18, a buckle 1 21 is fixedly installed on the outer surface of the ring sleeve 3 20, and the buckle 1 21 is arranged in a hook shape, and slide rails 24 are fixedly installed on both sides of the lower end of the transmission frame 23, and a slide rod 22 is slidably connected between the two sets of slide rails 24, and the slide rod 22 is fixedly connected to the buckle 1 21.

[0036] This scheme can achieve secondary reinforcement of the axial force meter by setting up a second fixing mechanism, ensure its stability and reliability in complex environments, further enhance the safety performance of the installation, and meet high-standard engineering requirements. Specifically: when the transmission ring 6 descends, the transmission frame 23 will be driven to descend through the horizontal bar 18 and the vertical bar 19, and the sliding bar 22 on the buckle 21 is slidably connected to the sliding rail 24 fixedly installed at the lower end of the transmission rod. Therefore, as the transmission frame 23 descends, the buckle 21 will be driven to rotate around the fixing ring 8 and deflect ninety degrees, so that the buckle 21 is clamped with the edge of the steel plate 2, thereby further enhancing the stability of the axial force meter body 3.

[0037] The fixing mechanism three includes a slot 28 opened inside the buckle 21, and the inside of the slot 28 is rotatably connected with the rotating shaft 25, a coil spring 26 is arranged on the front side of the buckle 21, one end of the rotating shaft 25 extends to the front side of the buckle 21 and is fixedly connected to one end of the coil spring 26, and a fixing column 27 is fixedly installed between the other end of the coil spring 26 and the buckle 21, and a buckle 29 is arranged inside the slot 28. The buckle 29 is arranged in a curved shape and is fixedly connected to the rotating shaft 25. A top block 30 is fixedly installed on one end of the buckle 29, and a cross plate 31 is fixedly installed on the other end of the buckle 29. The upper end of the cross plate 31 is spirally connected with a bolt 33, and a threaded groove 32 is arranged on the upper end surface of the steel plate 2 corresponding to the bolt 33.

[0038] By setting up a third fixing mechanism, the present scheme can further enhance the stability of the axial force meter, ensure its reliable performance in harsh environments, improve the stability of the overall structure, and meet higher engineering safety standards. Specifically: when the buckle 1 21 is engaged with the steel plate 2, the steel plate 2 will push the top block 30 on the buckle 29, causing the buckle 29 to deflect counterclockwise around the rotating shaft 25, and the cross plate 31 on the buckle 29 is tightly attached to the steel plate 2, and then the bolt 33 is twisted, and the bolt 33 is spirally connected through the threaded groove 32 on the steel plate 2, and cooperates with the buckle 29 to further increase the stability of the axial force meter body 3. At the same time, when it is necessary to release the installation, first release the fixing of the bolt 33, and then flip the telescopic rod 7 to make the buckle 1 21 away from the steel plate 2, and under the action of the coil spring 26, the rotating shaft 25 carrying the buckle 2 29 can be restored to its original position.

[0039] Four groups of the fixing mechanism 1, the fixing mechanism 2 and the fixing mechanism 3 are respectively arranged and dispersedly arranged in a ring shape.

[0040] Directions:

[0041] When the axial force meter body 3 needs to be installed on the steel plate 2 on the anchor bolt active head 1, first put the clamping ring of the axial force meter body 3 into the clamping groove on the steel plate 2, then start the telescopic rod 7, so that the telescopic rod 7 drives the slider 5 to slide down inside the slide groove 4, and the slider 5 will synchronously carry the transmission ring 6 to slide down synchronously, and the transmission ring 6 will synchronously carry the ring sleeve 10 to slide down, and the ring sleeve 10 will carry the connecting rod 11 to descend, and the connecting rod 2 13 on the ring sleeve 2 12 is synchronously connected with the connecting rod 11 to rotate with the connecting piece 15 on the plug rod 16, so the plug rod 16 will move to the slot 17 on the support column 14 and be inserted into the inside of the slot 17, so as to preliminarily fix and install the axial force meter body 3;

[0042] Secondly, when the transmission ring 6 descends, the transmission frame 23 is driven to descend through the horizontal rod 18 and the vertical rod 19, and the slide bar 22 on the buckle 21 is slidably connected with the slide rail 24 fixedly installed at the lower end of the transmission rod. Therefore, as the transmission frame 23 descends, the buckle 21 is driven to rotate around the fixed ring 8 and deflect 90 degrees, so that the buckle 21 is engaged with the edge of the steel plate 2, thereby further strengthening the stability of the axial force meter body 3;

[0043] Secondly, when the buckle 1 21 is engaged with the steel plate 2, the steel plate 2 will push the top block 30 on the buckle 29, causing the buckle 29 to deflect counterclockwise around the rotating shaft 25, so that the cross plate 31 on the buckle 29 is tightly attached to the steel plate 2, and then the bolt 33 is twisted, and the bolt 33 is spirally connected through the threaded groove 32 on the steel plate 2, and cooperates with the buckle 29 to further increase the stability of the axial force meter body 3. At the same time, when it is necessary to release the installation, first release the fixation of the bolt 33, and then flip the telescopic rod 7 to make the buckle 1 21 away from the steel plate 2, and under the action of the coil spring 26, the rotating shaft 25 carrying the buckle 29 can be restored to its original position.

[0044] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
