Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, and in particular to an auxiliary device for installing anchor bolts and its construction method. Background Technology

[0002] Anchor bolts, as an important auxiliary support method to prevent arch foot shrinkage and arch collapse during tunnel construction, are used in almost all ongoing tunnel projects. Meanwhile, to fully utilize the supporting role of anchor bolts on the arch frame, high requirements are placed on the installation angle of the bolts. Currently, the installation of anchor bolts in domestic tunnels mainly involves two methods: manual hand-held pneumatic rock drills and anchor bolt drilling rigs. Anchor bolt drilling rigs, due to their large size and the high space requirements for the swing arm, are severely limited in tunnel construction except for large-section tunnels and cannot be widely used. During the installation of manual hand-held pneumatic rock drills, the long drill rod makes it difficult for operators to maintain a sufficient working height to ensure a normal drilling angle. Furthermore, the thrust generated by the pneumatic leg and the huge reaction force during drilling make it extremely difficult for manual operators to control the angle.

[0003] Chinese patent document CN 218759970 U describes a positioning bracket for tunnel anchor bolts, but it still does not solve the problems of insufficient height for manual operation, large reaction force, and difficulty in angle control. Similarly, Chinese patent document CN 210127863 U describes a positioning platform for tunnel anchor bolts, but it also does not solve the above problems and has defects in use, so it needs to be improved. Summary of the Invention

[0004] This invention provides an auxiliary device for installing anchor bolts and its construction method, which solves the problems of cumbersome manual operation, inconvenient angle adjustment, inability to fully position according to the height of the steel arch frame, large overall structure of the device, and inconvenient installation and dismantling.

[0044] like Figure 1-6In this invention, an auxiliary device for installing a foot anchor bolt includes two support units 4 arranged opposite to each other, which are connected by two first connecting rods 3. A support unit 2 is detachably provided at the bottom of the support unit 4, and an adjustment unit 1 is provided in the middle of the support unit 2. A mounting seat 5 is slidably provided on the upper side of the two support units 4. A rock drill 6 is fixed on the mounting seat 5. The drill rod 7 located at the end of the rock drill 6 is inserted into a guide frame 8, which is set on a steel arch frame 9. This structure allows the support unit 2 to provide stable foundation support, lifting the support unit 4. The support unit 4 then provides a solid moving platform for the rock drill 6, ensuring the efficient operation of the rock drill 6. The drill rod 7, under the action of the guide frame 8, achieves high drilling accuracy while maintaining axial force balance, avoiding stress changes that could cause the drill rod 7 to deviate or break. When a large drilling angle is required, the height of the support unit 4 is too large, exceeding the height of the operator. In this case, it is difficult to drill using ordinary drilling methods, and it is also difficult to guarantee the drilling accuracy, resulting in low construction efficiency and high labor intensity for the operators. With this solution, the operators only need to ensure that the support unit 2 and the support unit 4 are fixed and stable.

[0045] The jacking motor 7 is connected to the mounting base 5 via gears. A rack is provided on the support unit 4. The gears and racks mesh. Due to the complex working conditions, the gears and racks themselves can adapt to high loads and have relatively low environmental requirements. The jacking motor 7 drives the gears to work, thereby enabling the mounting base 5 to move. The overall movement is convenient and efficient.

[0046] In a preferred embodiment, the support unit 4 includes a second sleeve 403, a vertical rod 401, and a first sleeve 402 arranged from top to bottom. The first sleeve 402 is connected to the support unit 2. The upper part of the second sleeve 403 is provided with a transition seat 404. The upper parts of the two vertical rods 401 are connected by an adjusting plate 405. The vertical rod 401 on the side closer to the steel arch frame 9 is lower in height. A disc 406 is provided in the middle of the vertical rod 401. The first connecting rod 3 is connected to the disc 406 by a pin 11. The insert rod 14 passes through the first connecting rod 3 and the disc 406. The adjusting plate 405 is equipped with a rack that meshes with the output gear of the jacking motor 7. This structure allows for easy adjustment of the height of the vertical rod 401, thereby ensuring that the adjusting plate 405 can be adjusted to the required drilling angle. The first connecting rod 3 can connect the two support units 4 to form a unified whole with strong overall rigidity. The disc 406 is equipped with multiple connecting holes, and the first connecting rod 3 can be quickly installed and removed through the insertion rod 14, resulting in better overall locking effect.

[0047] In the preferred embodiment, the adapter 404 has a fifth through hole 409 extending through its upper part. The two sides of the adjusting plate 405 are connected to the adapter 404 via pins 11, which pass through the fifth through hole 409. The adapter 404 has a first threaded hole 410 at its lower part, and a locking pin 15 passes through a second sleeve 403. The adapter 404 is connected to the second sleeve 403 via the locking pin 15. Multiple second connecting rods 12 are provided between the two adjusting plates 405. This structure allows the adapter 404 to adjust its angle as needed, ensuring good clamping and limiting effect on the adjusting plate 405 and constraining it. The adjusting plate 405 is hinged to the adapter 404 on the side closest to the steel arch frame 9. Combined with the two vertical rods 401, this structure can adapt to various scenarios and reduces operating costs.

[0048] like Figure 7 In the preferred embodiment, the adjusting plate 405 has a sixth through hole 411 and an oblong hole 412 on both sides. The sixth through hole 411 is located on the side closer to the guide frame 8, and the pin 11 passes through the sixth through hole 411 and the oblong hole 412. An angle gauge 413 is also provided on the adapter 404, which is farther from the guide frame 8. This structure allows for initial alignment using the laser unit, and the angle gauge 413 visually reflects the angle of the adjusting plate 405. That is, even when the supporting unit 2 and the ground form an angle, it is only necessary to ensure that the laser unit on the adjusting plate 405 is irradiated, and then observe the designed position of the anchor rod in the tunnel. The laser unit can be a laser pointer, which is small in size, easy to install and disassemble, has low operating cost, and good performance.

[0049] like Figure 8-16 In the preferred embodiment, the supporting unit 2 includes four display racks 10 symmetrically arranged on both sides of the adjusting unit 1. Each display rack 10 includes two fixed seats 1005 and four straight plates 1001 arranged opposite each other. A second round rod 1006 is fixed on the fixed seat 1005. One side of the straight plate 1001 is hinged to the second round rod 1006. The four straight plates 1001 are connected by a first support plate 1002. A pin 11 passes through the straight plate 1001 and the first support plate 1002. Two adjacent display racks 10 are connected by a second support plate 1003. The pin 11 passes through the second support plate 1003 and the straight plate 1001. A first sleeve 402 is connected to the fixed seat 1005. This structure allows the four display stands 10 to work together, forming a quadrilateral support. The quadrilateral support can change the area covered by the ground, thereby adjusting the support effect to cope with different soil surface conditions. At the same time, the first support plate 1002 and the second support plate 1003 can connect the different display stands 10 to form multiple triangles. The triangles have stability, and the overall structural strength is higher.

[0050] In the preferred embodiment, the fixing base 1005 has a protrusion 1007 on one side, a slot 1008 in the middle of the protrusion 1007, and a seventh through hole 1009 through both sides of the slot 1008. The bottom of the first sleeve 402 has a T-shaped plate 407, and a fourth through hole 408 on the T-shaped plate 407. The pin 11 passes through the fourth through hole 408 and the seventh through hole 1009. A weight-reducing groove 1004 is through the straight plate 1001. This structure makes the overall assembly and disassembly convenient and provides a better connection effect.

[0051] In a preferred embodiment, the adjustment unit 1 includes two oppositely arranged connecting seats 101. Each connecting seat 101 has an ear plate 105. The ear plate 105 has a first through hole 106. An anti-rotation rod 102 passes through the first through hole 106. The connecting seat 101 has a cavity 103 in the middle. The cavity 103 has a notch 104 on the side near the ear plate 105. The cavity 103 has a groove 112 on one side. A first screw 110 passes through the middle of the anti-rotation rod 102. A frustum 113 is threaded to the bottom of the first screw 110. A stop block 114 is provided at the bottom of the frustum 113. The stop block 114 is inserted into the two grooves 112. The first screw 110 passes through two oppositely arranged fixing plates 115. Each end of the fixing plate 115 has a connecting sleeve 116. The connecting sleeve 116 is connected to the support unit 2 through a second screw 117. This structure allows for quick connection of the connecting seat 101 by adjusting its different states. The connecting seat 101 can be folded. During installation, because the position of the ear plate 105 is fixed, the nut 13 and the pin 11 lock the first screw 110 at the anti-rotation rod 102 on both sides of the height direction, thereby pressing the stop block 114 below the frustum 113 into the groove 112. The ear plate 105 is set on the connecting seat 101, thus allowing the side walls of the two connecting seats 101 to be tightly pressed together. The two grooves 112 connect to form the receiving cavity of the stop block 114. At this time, the stop block 114 and the two connecting seats 101 are interlocked. The fixing plate 115 and the connecting sleeve 116 are eccentrically installed to ensure the two fixed... When the fixed plate 115 is stacked, the four connecting sleeves 116 are at the same height. The connecting sleeves 116 are locked to the supporting unit 2 by the second screw 117. The overall installation is convenient. When it is necessary to disassemble and fold, the pin 11 on the first screw 110 is released to release the first screw 110. The height of the first screw 110 is pulled outward, and then the stop block 114 is moved out of the groove 112. At this time, there is only one disengaged state. The connecting seat 101 can rotate around the anti-rotation rod 102, so that it is in a stacked state with another connecting seat 101 in the height direction. At this time, all the display racks 10 are on the same side, which occupies little space and is convenient for storage and handling. It is conducive to construction personnel to shuttle and transfer between different construction points, and the overall utilization efficiency is high.

[0052] In a preferred embodiment, the supporting unit 2 includes four display racks 10 symmetrically arranged outside the adjusting unit 1. Each display rack 10 is provided with a fixed seat 1005. A mounting plate 118 is provided on one side of the second screw 117. The mounting plate 118 is hinged to the fixed seat 1005 via a pin 11. Multiple sliding grooves 107 are provided in parallel within the first through hole 106. Multiple protrusions 108 are provided on the outer side walls of both sides of the sliding grooves 107. The protrusions 108 and the sliding grooves 107 are inserted into each other. A second through hole 109 is provided in the middle of the anti-rotation rod 102. A first screw 110 passes through the second through hole 109. The first screw 110 is connected to the anti-rotation rod 102 via a nut 13. Two third through holes 111 are provided in parallel on the first screw 110. The pin 11 passes through the third through holes 111. The length of the protrusion 108 of the anti-rotation rod 102 is the same as the width of the ear plate 106 of the connecting seat 101. This structure ensures that the anti-rotation rod 102 can only drive one connecting seat 101 to rotate, and the rotation of the anti-rotation rod 102 does not affect the state of the other connecting seat 101, making the overall operation more stable and efficient.

[0053] like Figure 17-18 In the preferred embodiment, the guide frame 8 includes a C-shaped plate 801, with base plates 807 on both sides of the C-shaped plate 801. A tube 802 is provided on the upper part of the base plate 807, and a drill rod 7 passes through the tube 802. A bolt 803 is threadedly connected to the tube 802. One side of the bolt 803 is connected to a pressure plate 804 via a locking pin 15. The bolt 803 has a second threaded hole 808, and the pressure plate 804 has a stepped hole 809. A first round rod 810 is provided on the outer side of the tube 802. A third threaded hole 812 is provided on the first round rod 810, and a locking pin 15 is provided in the third threaded hole 812. A limiting plate 805 is hinged to the tube 802 via the first round rod 810. A magnetic seat 806 is provided at the bottom of the limiting plate 805, and a knob 811 is provided on the magnetic seat 806. This structure allows for the following steps: after cleaning the bottom plates on both sides of the steel arch frame 9 according to the designed height, adjusting the position, rotating the knob 811 to attach the magnetic seat 806 to the bottom plate, and then clamping the C-shaped plate 801 onto the steel arch frame 9. At this point, rotating the bolt 803 will press the pressure plate 804 against the middle side wall of the steel arch frame. Finally, using external tools to appropriately tap the pressure plate 804 will cause both ends of the pressure plate 804 to be clamped against the inner side wall of the steel arch frame, thus ensuring the stability of itself and the steel arch frame 9 structure. The limiting plate 805 ensures stable support for the C-shaped plate 801 within a certain height range, ensuring accurate drilling position and drilling angle of the drill rod 7, resulting in better overall construction effect. It also provides good limiting support for the drill rod 7, ensuring that the drilling height of different steel arch frames 9 is the same, thereby ensuring better accuracy in tunnel construction and more stable overall stress.

[0054] In the preferred embodiment, the construction method for the auxiliary device for installing the anchor bolt includes the following steps:

[0055] S1. First, complete the fabrication of the guide frame 8. According to the preset height, install the guide frame 8 on the steel arch frame 9.

[0056] S2. Level the ground inside the steel arch frame 9, then complete the installation of the adjustment unit 1 and the support unit 2, and adjust the appropriate unfolded area.

[0057] S3. Complete the installation of the support unit 4 on the support unit 2, and adjust the alignment angle of the adjustment plate 405. Observe through the jacking motor 16.

[0058] S4. Install the mounting base 5 and the rock drill 6 onto the support unit 4 and perform initial adjustments;

[0059] S5. Use the laser unit on the mounting base 5 to make a precise measurement, then finely adjust the positioning and lock it, and then install the drill rod 7 on the rock drill 6.

[0060] S6. After the drill rod 7 passes through the guide frame 8, turn on the rock drill 6 and at the same time turn on the jacking motor 16 on the mounting base 5 to carry out drilling.

[0061] S7. When the designed hole depth is reached, the movement direction of the jacking motor 16 is changed, and at the same time the rock drill 6 works in reverse to pull out the drill rod 7.

[0062] S8. After the grout rolls are filled into the hole or grouting is completed according to the design requirements, the anchor rod is inserted into the hole. When it is difficult to insert it manually, the anchor rod is inserted into the front end of the rock drill 6. Repeat the above steps to send the anchor rod into the hole and complete the construction of the anchor rod.

[0063] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
