Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to an advanced small guide pipe angle positioning device. Background Technology

[0002] Pre-support using small guide pipes is a highly effective support measure for stabilizing the surrounding rock at the tunnel face. During tunnel excavation, in sections where the surrounding rock is fractured, has poor self-stabilizing capacity, or has abundant groundwater requiring pre-sealing, pre-support using small guide pipes combined with grouting can reinforce the surrounding rock within a certain range. Combined with a steel frame, it forms a pre-support system that controls deformation, collapse, and rockfall in weak surrounding rock. Currently, during tunnel construction, workers often struggle to control the external angle of the pre-supporting small guide pipes during installation. This angle is easily affected by the movement of the pneumatic drill, leading to variations in the pipe angle, sometimes even resulting in pipe crossing. This can cause the pipes to fail to effectively reinforce the surrounding rock at the tunnel face, making the top of the face prone to rockfall and collapse, compromising worker safety, and impacting construction progress.

[0003] Application No.: 202420736608.X discloses an advanced small guide tube positioning fixture. By setting the positioning tube, it cooperates with the positioning seat and the preset angle of the preset hole. After its insertion, it plays a guiding role in the use of the drill rod structure. The angle of the advanced small guide tube is determined by the positioning tube on the fixture, thereby solving the problems of difficult angle control and low accuracy. Moreover, the reusability of the device for disassembly and installation can save certain costs and improve construction quality.

[0004] When in use, the angle of the positioning tube is fixed and cannot be adjusted according to needs, thus limiting its applicability. Furthermore, when not in use, the length of the positioning tube extends, making it inconvenient to place the equipment. During transportation, if a collision occurs, the angle of the positioning tube may tilt, affecting its position and impacting the quality of the project during use. Utility Model Content

[0005] The purpose of this invention is to overcome the limitations of current positioning tubes, which cannot be adjusted according to the needs of on-site use and cannot be retracted, causing the positioning tube angle to tilt during transportation. Therefore, this invention proposes an advanced small guide tube angle positioning device.

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

[0007] An advanced small catheter angle positioning device includes a positioning seat with an opening. A rotating shaft is connected to the side wall of the opening. The rotating shaft passes through the side wall of the opening and extends to one side of the positioning seat. A rotating disk is connected to the end of the rotating shaft. An adjusting plate is connected to the rotating shaft. A guide tube is connected to the surface of the adjusting plate. A limit component is provided on the positioning seat.

[0008] The adjusting plate can rotate under the action of the rotating shaft. The angle of the adjusting plate can be controlled according to the needs of use, thereby increasing the applicable range and ensuring the stability of the drill rod during operation.

[0009] Preferably, a limiting plate is connected to one side of the upper surface of the positioning seat, a lead screw is threaded onto the limiting plate, a pressure plate is rotatably connected to the lower end of the lead screw, a connecting plate is connected to one end of the pressure plate, a limiting rod is connected to one side of the surface of the connecting plate, and a limiting port is provided above the adjusting plate, with the limiting port corresponding to the limiting rod.

[0010] The pressure plate connects the positioning seat to the steel arch frame, making it easy to determine the position of the guide tube. The cooperation between the connecting plate and the limiting rod can limit the upper part of the adjusting plate when not in use, preventing the adjusting plate from tilting and affecting the angle of the guide tube.

[0011] Preferably, two sleeves are hinged to the surface of the adjusting plate, and an extension rod is slidably connected inside the sleeve. The end of the extension rod away from the sleeve is hinged to the lower surface of the connecting plate. A second spring is connected inside the sleeve, and one end of the second spring is connected to the end of the extension rod.

[0012] When the limiting rod separates from the limiting port, the second spring rebounds and causes the adjusting plate to tilt. The angle of the adjusting plate can then be adjusted again according to the construction requirements. During construction, the sleeve, the second spring, and the extension rod provide support for the upper part of the adjusting plate.

[0013] Preferably, the limiting component includes a mounting plate disposed on the side of the positioning seat, a rod connected to the mounting plate, a pull plate connected to the upper end of the rod, the lower end of the rod passing through the mounting plate and extending to the bottom of the mounting plate, a first spring sleeved on the rod, the upper end of the first spring connected to the bottom of the pull plate, the lower end of the first spring connected to the mounting plate, and a plurality of limiting grooves provided on the rotating disk, the lower end of the rod extending into one of the limiting grooves.

[0014] The insertion rod and the first spring allow the insertion rod to limit the rotation of the rotating disk, and the rotation of the adjustment plate can be restricted by the rotation shaft.

[0015] Preferably, the pull plate is provided with mounting holes, and the side wall of the positioning seat is provided with multiple limiting holes. A connecting rod is inserted through the mounting hole, and one end of the connecting rod extends into one of the limiting holes.

[0016] Preferably, the side wall of the positioning seat is provided with an angle mark, which corresponds to the rotating disk.

[0017] The angle markings allow you to quickly determine the angular position of the rotating disk and the angle that needs to be rotated.

[0018] Compared with the prior art, the beneficial effects of this utility model are: by cooperating with the adjusting plate, rotating shaft and limiting components, the guide tube is set on the adjusting plate, and the angle of the adjusting plate can be quickly adjusted according to the needs of on-site use, thereby improving the applicability. When not in use, the angle of the adjusting plate can be changed to protect the guide tube and prevent the guide tube from tilting, which would affect subsequent use. Attached Figure Description

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] Reference Figures 1-4 An advanced small guide pipe angle positioning device includes a positioning seat 1 with an opening 18. A rotating shaft 19 is connected to the side wall of the opening 18, passing through the side wall of the opening 18 and extending to one side of the positioning seat 1. A rotating disk 7 is connected to the end of the rotating shaft 19. An angle mark is provided on the side wall of the positioning seat 1, corresponding to the rotating disk 7. The angle mark is set with the horizontal as the zero mark, and then set according to the scale line. This allows for quick determination of the position of the rotating disk 7 and the required rotation angle. An adjusting plate 13 is connected to the rotating shaft 19, and the adjusting plate 13 can rotate under the action of the rotating shaft 19. The angle of the adjusting plate 13 can be controlled according to the needs of use, increasing the range of use and ensuring the drill rod operates smoothly. To ensure stability, the surface of the adjusting plate 13 is connected to a guide tube 12. The drill rod passes through the guide tube 12 for operation, which guides the drill rod and ensures its stability during operation. The positioning seat 1 is equipped with a limit component, which limits the adjusting plate 13 to prevent instability during operation and ensures that the adjusting plate 13 does not affect the operation. When the guide tube 12 is not in use, it can be placed vertically by the adjusting plate 13 to protect it. This ensures that the angle between the guide tube 12 and the adjusting plate 13 is the same, making it easy to adjust during use and ensuring the accuracy of operation. According to the site requirements, the entire equipment can be flipped so that the lead screw 9 is at the bottom, and then the operation can be started again to avoid the lead screw 9 blocking the use of the entire equipment due to insufficient position at the top.

[0027] Reference Figures 1-3 A limiting plate 8 is connected to one side of the upper surface of the positioning seat 1. A screw 9 is threaded onto the limiting plate 8. A pressure plate 10 is rotatably connected to the lower end of the screw 9. A connecting plate 14 is connected to one end of the pressure plate 10. A limiting rod 17 is connected to one side of the surface of the connecting plate 14. A limiting port 11 is provided above the adjusting plate 13. The limiting port 11 is correspondingly set with the limiting rod 17. In use, the screw 9 can control the pressure plate 10 to move up and down. The pressure plate 10 connects the entire positioning seat 1 to the steel arch frame, which facilitates the determination of the position of the guide tube 12. The cooperation of the connecting plate 14 and the limiting rod 17 can limit the upper part of the adjusting plate 13. When not in use, the guide tube 12 is protected to prevent the angle of the guide tube 12 from tilting during transportation.

[0028] Reference Figure 1 and Figure 2 Two sleeves 16 are hinged to the surface of the adjusting plate 13. An extension rod 15 is slidably connected inside the sleeve 16. The end of the extension rod 15 away from the sleeve 16 is hinged to the lower surface of the connecting plate 14. A second spring 20 is connected inside the sleeve 16. One end of the second spring 20 is connected to the end of the extension rod 15. The arrangement of the sleeves 16, the second spring 20 and the extension rod 15 allows the adjusting plate 13 to tilt when the limiting rod 17 separates from the limiting port 11 and the second spring 20 rebounds. The angle of the adjusting plate 13 can then be adjusted again according to the construction requirements. During construction, the arrangement of the sleeves 16, the second spring 20 and the extension rod 15 can provide support for the upper part of the adjusting plate 13.

[0029] Reference Figure 1 The limiting component includes a mounting plate 5 disposed on the side of the positioning seat 1. A rod 3 is connected to the mounting plate 5. The upper end of the rod 3 is connected to a pull plate 2. The lower end of the rod 3 passes through the mounting plate 5 and extends to the bottom of the mounting plate 5. A first spring 4 is sleeved on the rod 3. The upper end of the first spring 4 is connected to the bottom of the pull plate 2, and the lower end of the first spring 4 is connected to the mounting plate 5. The rotating disk 7 is provided with multiple limiting grooves 6. The arrangement of the rod 3 and the first spring 4 enables the rod 3 to limit the rotation of the rotating disk 7. Furthermore, the setting of the rotating shaft 19 can limit the adjustment. The rotation of the adjustment plate 13 prevents it from rotating during use. The lower end of the insertion rod 3 extends into one of the limiting grooves 6. The pull plate 2 is provided with a mounting hole, and the side wall of the positioning seat 1 is provided with multiple limiting holes 21. A connecting rod 22 is inserted through the mounting hole, and one end of the connecting rod 22 extends into one of the limiting holes 21. The connection rod 22 and the limiting hole 21 can limit the insertion rod 3. When adjusting the adjustment plate 13, the insertion rod 3 is prevented from limiting the rotating disk 7 under the action of the first spring 4, thus affecting the adjustment of the adjustment plate 13.

[0030] In use, first pull the pull plate 2 upwards. The pull plate 2 moves the insertion rod 3 upwards together, and the first spring 4 is stretched. Then, use the connecting rod 22 to limit the pull plate 2. Rotate the lead screw 9. The lead screw 9 moves the pressure plate 10 and the connecting plate 14 upwards together. The connecting plate 14 moves the limit rod 17 together. At this time, the second spring 20 in the sleeve 16 will return to its original position, which will push the adjusting plate 13. The adjusting plate 13 changes from vertical to inclined under the action of the rotating shaft 19. Then, rotate the rotating disk 7 according to the required drilling angle. The rotating disk 7 controls the rotation of the rotating shaft 19, thereby driving the adjusting plate 13 to rotate. Rotate to the appropriate position according to the angle marking. After placement, pull out the connecting rod 22. At this time, the first spring 4 returns to its original position, and the first spring 4 drives the insert rod 3 to return to its original position. The insert rod 3 moves into a limiting groove 6 in the rotating disk 7, thereby limiting the rotating disk 7, and then the operation begins. When the adjusting plate 13 needs to be collected after use, pull out the insert rod 3 again through the pull plate 2 to limit the pull plate 2. Then control the screw 9 to rotate, driving the pressure plate 10 and the connecting plate 14 to move upward. The operator manually pushes the adjusting plate 13, and the adjusting plate 13 is in a vertical state. Then rotate the screw 9 again, and the screw 9 controls the limiting rod 17 to move into the limiting port 11. Pull out the connecting rod 22 again, and the insert rod 3 limits the rotating disk 7.
