Description

Technical Field

[0001] This invention relates to the technical field of assisted insertion of pre-implantation catheters, and more particularly to an auxiliary device for the insertion of pre-implantation catheters. Background Technology

[0002] Tunnel engineering involves constructing structures underground, underwater, or within mountains to lay railways or build highways for motor vehicles. To determine the tunnel's location, construction methods, and technical solutions such as support and lining types, surveys must be conducted on the topography and geological conditions of the tunnel's location, as well as the hydrological conditions, including the distribution and volume of groundwater. Furthermore, the type of surrounding rock must be understood during tunnel surveying and excavation. During tunnel excavation, pre-supporting pipes are used for grouting in areas with short self-stabilization times, such as weak and fractured zones, shallow buried sections, biased pressure sections at the tunnel entrance, sandy sections, gravel sections, and fault fracture zones. However, when driving in pre-supporting pipes, workers first need to drill multiple sets of pre-drilled holes at the same angle on one side of the guide arch. Currently, most methods involve workers using an angle gauge to pre-aim at the drilling points, then drilling holes at those locations using an electric drill, and then repeatedly measuring before drilling each hole. This process is cumbersome and reduces work efficiency. Therefore, we propose an auxiliary device for inserting advanced small catheters. Summary of the Invention

[0021] Example

[0022] like Figure 1-4As shown, the present invention proposes an auxiliary device for inserting advanced small catheters, comprising a movable component 1 and an installation and adjustment mechanism 2 mounted on the intermediate beam of a guide arch. The movable component 1 includes two sets of drive wheels 101 located below the intermediate beam of the guide arch. A hub motor is installed inside each drive wheel 101, providing driving force to the drive wheel 101. The outer ring of the drive wheel 101 is in close contact with the lower surface of the intermediate beam of the guide arch. The installation and adjustment mechanism 2 includes sliding rods 201 and connecting frames 202 located on both sides of the drive wheel 101. The sliding rods 201 are rectangular, and the outer ring of the sliding rods 201 is fitted with connecting frames 203. One end of the connecting frame 203 is slidably connected to the slide rod 201. A mounting plate is provided on the side of the slide rod 201 near the drive wheel 101. One side of the mounting plate is fixedly connected to one side of the drive wheel 101. One end of the slide rod 201 is fixedly connected to the mounting plate. Two sets of strong springs 204 are provided between the connecting frame 203 and the mounting plate. One end of the strong spring 204 is fixedly connected to one side of the mounting plate, and the other end of the strong spring 204 is fixedly connected to one side of the connecting frame 203. Each set of connecting frames 202 and 203 has a driven wheel 102 at its top. Multiple sets of driven wheels 102 are respectively installed on both sides of the middle beam of the guide arch frame. The 04 setting allows the connecting frame 203 to quickly return to its original position after sliding along the slide bar 201, thus ensuring a tight fit between the driven wheel 102 and both sides of the guide arch beam. This allows it to be used with guide frame inner beams of different widths. Each set of driven wheels 102 has a rotating hole, and the tops of the connecting frame 202 and the connecting frame 203 are respectively installed with corresponding rotating holes on the driven wheels 102. Both the connecting frame 202 and the connecting frame 203 are rotatably connected to the driven wheels 102. Synchronizing rods 9 are provided between the two sets of connecting frames 202 and between the two sets of connecting frames 203. The two ends of one set of synchronizing rods 9 are respectively fixedly connected to the two sets of connecting frames 202. The two ends of another set of synchronizing rods 9 are fixedly connected to the two sets of connecting frames 203 respectively. The synchronizing rods 9 can strengthen and stabilize the two sets of connecting frames 202 or the two sets of connecting frames 203. Multiple sets of the present invention can be installed on the middle beam of the guide arch frame as needed. Equidistant connecting rods can be connected between the two sets of the present invention, so that simultaneous multi-hole pre-drilling operation can be better performed. The moving component 1 and the installation adjustment mechanism 2 are set to slide and adjust along the inner beam of the guide arch frame, so that multiple sets of installation holes of the advanced small guide tube can be pre-drilled simultaneously, thereby greatly improving the work efficiency and facilitating the efficient driving of the advanced small guide tube.

[0023] A mounting bracket 3 is installed at the ends of the slide rod 201 and the connecting bracket 202 that are far apart from each other. The mounting bracket 3 is open on all four sides and top, which facilitates the installation of the self-tapping screw 7. The ends of the slide rod 201 and the connecting bracket 202 that are far apart from each other are respectively installed on the inner walls of the two sides of the mounting bracket 3. Both the slide rod 201 and the connecting bracket 202 are fixedly connected to the mounting bracket 3. A rear adjustment mechanism 4 is provided on both sides of the mounting bracket 3 near the slide rod 201. The rear adjustment mechanism 4 includes a guide rail 401. A hinge seat 10 is installed on the top of the guide rail 401. The mounting end of the hinge seat 10 is fixedly connected to the top of the guide rail 401. Next, hinge seats 21 are respectively provided on both sides of the mounting frame 3 near the slide rod 201. The mounting end of the hinge seat 21 is fixedly connected to the mounting frame 3. An electric telescopic rod 402 is installed between the hinge seat 10 and the hinge seat 21. The two ends of the electric telescopic rod 402 are rotatably connected to the hinge seat 10 and the hinge seat 21 respectively. The electric telescopic rod 402 allows the guide rail rod 401 to be angled and pulled by the hinge seat 10 and the hinge seat 21, making the guide rail rod 401 more stable in the installed state. A positioning rod 403 is provided at one end of the guide rail rod 401. One end of the guide rod 401 is installed corresponding to one side of the mounting bracket 3. The positioning rod 403 is fixedly connected to the mounting bracket 3. One end of the guide rod 401 is rotatably connected to the positioning rod 403. An L-shaped mounting plate 5 is provided on one side of the mounting bracket 3. Movable shafts 404 are provided on both sides of the L-shaped mounting plate 5. One end of the movable shaft 404 is fixedly connected to the L-shaped mounting plate 5. The outer ring of the movable shaft 404 fits against the inner ring of the guide rod 401. The movable shaft 404 and the inner ring of the guide rod 401 are slidably connected. A shaft hole is opened on the L-shaped mounting plate 5. A bushing 12 is installed in the shaft hole. The outer ring of the bushing 12 fits tightly against the shaft hole. An angle sensor is provided on one side of the L-shaped mounting plate 5. Angle sensors are electrically connected to electric telescopic rod 402 and electric telescopic rod 804, respectively. The angle sensors allow for quick adjustment of the pre-processed angle of the self-tapping screw 7. A motor 6 is mounted on top of the L-shaped mounting plate 5. The mounting end of the motor 6 is fixedly connected to the L-shaped mounting plate 5. The output end of the motor 6 is connected to the self-tapping screw 7. One end of the self-tapping screw 7 is fixedly connected to the output end of the motor 6. The outer ring of the self-tapping screw 7 is fitted with the inner ring of the bushing 12. The rear adjustment mechanism 4 allows for adjustment of the angle positions of the L-shaped mounting plate 5, the motor 6, and the self-tapping screw 7, thereby better meeting the needs of construction at different angles.

[0024] The mounting bracket 3 has front adjustment mechanisms 8 on both sides near the connecting bracket 202. Each front adjustment mechanism 8 includes two sets of adjustment brackets 801 located on the inner walls of both sides of the mounting bracket 3 and a stabilizing bracket 802 sleeved on the outer ring of the self-tapping screw 7. One end of each adjustment bracket 801 is fitted with a mounting seat 13, the mounting end of which corresponds to the mounting bracket 3 and is fixedly connected to it. One end of each adjustment bracket 801 is rotatably connected to the mounting seat 13. Mounting seats are provided on both sides of the stabilizing bracket 802. Mounting base 214 has its mounting end fixedly connected to the stabilizing bracket 802. Mounting base 214 is also installed at the other end of the adjusting bracket 801, which is rotatably connected to mounting base 214. The stabilizing bracket 802 has a mounting groove, in which a nut 803 is placed. The outer ring of the nut 803 is installed correspondingly to the mounting groove. The outer ring of the self-tapping screw 7 meshes with the inner ring of the nut 803. The nut 803 allows the self-tapping screw 7 to move forward while rotating. The system allows for rapid pre-drilling of small guide tubes, and the stabilizing bracket 802 guides the movement of the self-tapping screw 7, ensuring its stability during installation and operation. One side of the adjusting bracket 801 is equipped with an electric telescopic rod 804, one end of which is connected to a mounting base 15. The mounting end of the mounting base 15 is correspondingly installed on one side of the adjusting bracket 801, and the mounting base 15 is fixedly connected to the adjusting bracket 801. The other end of the electric telescopic rod 804 is equipped with a mounting seat. Mounting base 416 is installed at the mounting end corresponding to mounting bracket 3. Mounting base 416 is fixedly connected to mounting bracket 3. The two ends of electric telescopic rod 2804 are rotatably connected to mounting base 315 and mounting base 416 respectively. The electric telescopic rod 2804 can adjust the angle of the adjusting bracket 801. The front adjustment mechanism 8 can better cooperate with the rear adjustment mechanism 4, so that the angle of the self-tapping screw 7 can be quickly adjusted, thereby accelerating the effective pre-drilling operation of the advanced small guide tube.

[0025] In this embodiment, multiple sets of the present invention can be installed on the middle beam of the guide arch frame as needed. The operator first pulls the connecting frame 203 to one side, causing the connecting frame 203 to drive the driven wheel 102 to slide along the slide rod 201. At this time, the strong spring 204 is in a stretched state. Then, the driven wheel 102 is installed correspondingly to both sides of the middle beam of the guide arch frame. Then, the operator releases the connecting frame 203, allowing the connecting frame 203 to be repositioned by the strong spring 204, thus fitting the driven wheel 102 to both sides of the middle beam of the guide arch frame. At the same time, the driving wheel 101... The outer ring is fitted to the lower surface of the middle beam. Then the operator removes the self-tapping screw 7, so that the mounting end of the self-tapping screw 7 corresponds to the output end of the motor 6. At the same time, the top of the self-tapping screw 7 meshes with the inner ring of the nut 803, thus completing the overall installation of the equipment. Then the operator powers on the drive wheel 101 and starts it. The drive wheel 101 drives the driven wheel 102 and the mounting bracket 3 to slide along the guide arch through the installation adjustment mechanism 2. When the drive wheel 101 slides to the pre-drilled position, the drive wheel 101 stops working and is locked.

[0026] The operator then uses an angle sensor to detect the angle of the self-tapping screw 7. The angle sensor transmits the detection signal to both the electric telescopic rod 402 and the electric telescopic rod 804. The electric telescopic rods 402 and 804 are then energized and adjusted to match the tip angle of the self-tapping screw 7 with the pre-drilling position. The operator then energizes the motor 6, causing it to rotate the self-tapping screw 7. The rotation of the self-tapping screw 7, through its meshing with the nut 803, causes it to move forward. This movement of the self-tapping screw 7 causes the L-shaped mounting plate 5 and the motor 6 to follow suit. The movement of the L-shaped mounting plate 5 causes the moving shaft 404 to slide along the guide rail 401, thus enabling the self-tapping screw 7 to drill a hole, thereby completing the pre-drilling operation for inserting the advanced small guide tube.
