Description

Technical Field

[0001] This application relates to the field of water conservancy projects, and particularly to a construction device for a horizontal drill for advanced geological prediction of small-section tunnels in water conservancy projects. Background Art

[0002] During the construction of water conservancy projects, in order to meet the requirements of water diversion, drainage, and laying of power supply lines during the construction process, small-section tunnel construction is usually carried out according to the specific needs of the project. The construction of small-section tunnels is a complex and delicate process that requires comprehensive consideration of geological conditions, engineering requirements, construction techniques, and safety and environmental protection factors. Through scientific planning, careful construction, and strict management, the construction quality and safety of the tunnel can be ensured.

[0003] During the small-section construction process, in order to reduce the drilling and use of explosive charges for cut holes and increase the footage per cycle of the tunnel, a tunnel drilling jumbo composed of a horizontally arranged drill rig and a vehicle is usually used as a construction device to achieve the construction of the tunnel in the horizontal direction.

[0004] In view of the above related technologies, the position of the drill rig during the tunnel construction process is usually fixed, which is not convenient for quickly realizing the construction of different positions of the tunnel, and the applicability is poor. Summary of the Utility Model

[0005] In order to facilitate the quick realization of the construction of different positions of the tunnel and improve the applicability, this application provides a construction device for a horizontal drill for advanced geological prediction of small-section tunnels in water conservancy projects.

[0006] The construction device for a horizontal drill for advanced geological prediction of small-section tunnels in water conservancy projects provided by this application adopts the following technical solutions:

[0007] A construction device for a horizontal drill for advanced geological prediction of small-section tunnels in water conservancy projects includes a vehicle body, an installation platform, and a drill rig. The installation platform is arranged on the vehicle body. The installation platform includes a fixed seat, a rotating seat, an adjusting seat, and an installation seat. The rotating seat is rotatably installed on the fixed seat. The fixed seat is provided with a rotating mechanism for driving the rotating seat to rotate. The rotating seat is provided with a first moving mechanism for driving the adjusting seat to move in the x-axis direction. The adjusting seat is provided with a second moving mechanism for driving the installation seat to move in the y-axis direction. The drill rig is installed on the installation seat.

[0008] By adopting the above technical solution, during the construction of the tunnel, the construction in the horizontal direction of the tunnel is realized through the drill rig. During the construction process, the first motion mechanism drives the adjusting seat to move along the x-axis direction, and the second motion mechanism drives the mounting seat to move along the y-axis direction, which facilitates quickly realizing the drilling process of the tunnel at different horizontal positions by the drill rig. At the same time, the setting of driving the rotating seat to rotate through the rotating mechanism facilitates the drill rig to process more different positions of the tunnel at different angles, with strong applicability.

[0009] Optionally, the first motion mechanism includes an x-axis motion motor and an x-axis motion lead screw. The x-axis motion lead screw is rotatably installed on the rotating seat and is arranged along the x-axis direction. The x-axis motion lead screw passes through the adjusting seat and is in threaded cooperation with the adjusting seat. The x-axis motion motor is used to drive the x-axis motion lead screw to rotate, and the adjusting seat is slidably fitted to the rotating seat along the x-axis direction.

[0010] By adopting the above technical solution, when the x-axis motion motor drives the x-axis motion lead screw to rotate, the adjusting seat moves along the x-axis direction due to the threaded cooperation with the x-axis motion lead screw and under the limiting action of the rotating seat, thereby realizing the adjustment of the x-axis position of the drill rig in the horizontal direction, which is convenient and stable.

[0011] Optionally, the second motion mechanism includes a y-axis telescopic cylinder arranged along the y-axis. The cylinder body of the y-axis telescopic cylinder is installed on the adjusting seat, and the piston rod of the y-axis telescopic cylinder is installed on the mounting seat.

[0012] By adopting the above technical solution, when the y-axis telescopic cylinder drives its piston rod to move, it drives the mounting seat to move along the y-axis direction, thereby realizing the adjustment of the y-axis position of the drill rig in the horizontal direction, which is convenient and fast.

[0013] Optionally, the mounting seat is fixedly installed with a mounting guide block, and the top of the adjusting seat is provided with a mounting guide groove extending along the y-axis direction. The mounting guide block is slidably fitted in the mounting guide groove.

[0014] By adopting the above technical solution, the cooperation between the mounting guide block and the mounting guide groove plays a further limiting role in the sliding of the mounting seat, which is beneficial to further ensuring the stability of the mounting seat during sliding.

[0015] Optionally, the rotating mechanism includes a rotating shaft, a rotating motor, and a commutation component. The rotating shaft is fixedly installed on the rotating seat, and the rotating motor is installed on the fixed seat and drives the rotating shaft to rotate through the commutation component.

[0016] By adopting the above technical solution, when the rotating motor drives the rotating shaft to rotate through the commutation component, the rotating seat, the adjusting seat, and the mounting seat rotate together, thereby finally realizing the adjustment of the rotation angle of the drill rig. The setting of the commutation component facilitates the rotating motor to finally realize the rotation of the drill rig at different installation positions, with strong applicability.

[0017] Optionally, the commutation component includes a worm gear and a worm. The worm is fixedly installed at the output end of the rotating motor, and the worm gear is coaxially and fixedly installed on the rotating shaft and meshes with the worm.

[0018] By adopting the above technical solution, when the rotating motor drives the worm to rotate, the worm gear drives the rotating shaft and the rotating seat to rotate together. The self-locking effect between the worm gear and the worm is beneficial to ensuring the stability of the position where the rotating seat is located after rotation.

[0019] Optionally, the rotating seat is provided with a rotating guide block, and the fixed seat is provided with a rotating guide groove arranged in an arc shape. The rotating guide block is slidably fitted in the rotating guide groove.

[0020] By adopting the above technical solution, the cooperation between the rotating guide block and the rotating guide groove plays a further limiting role in the rotation of the rotating seat, which is beneficial to fully ensuring the stability of the rotating seat during rotation.

[0021] Optionally, the rotating guide block includes a guide fixing part and a guide roller. The guide fixing part is fixedly installed on the rotating seat, the guide roller is rotatably installed on the guide fixing part, and the guide roller is in rolling fit with the rotating guide groove.

[0022] By adopting the above technical solution, the setting of the guide roller reduces the friction force when the rotating guide block slides in the rotating guide groove, which is beneficial to reducing the wear of the rotating guide block caused by friction and facilitating the guarantee of the service life of the rotating guide block.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. During the construction process, driving the adjusting seat to move along the x-axis direction by the first motion mechanism and driving the mounting seat to move along the y-axis direction by the second motion mechanism facilitate quickly realizing the drilling of the tunnel by the drilling rig at different horizontal positions. At the same time, the setting of driving the rotating seat to rotate by the rotating mechanism facilitates the drilling rig to process more different positions of the tunnel at different angles, and has strong applicability.

[0025] 2. When the rotating motor drives the rotating shaft to rotate through the commutation component, the rotating seat, the adjusting seat and the mounting seat rotate together, so as to finally realize the adjustment of the rotation angle of the drilling rig. The setting of the commutation component facilitates the rotating motor to finally realize the rotation of the drilling rig at different installation positions, and has strong applicability.

[0026] 3. The setting of the guide roller reduces the friction force when the rotating guide block slides in the rotating guide groove, which is beneficial to reducing the wear of the rotating guide block caused by friction and facilitating the guarantee of the service life of the rotating guide block.

Specific embodiments

[0031] The following will Figure 1 and Figure 2 further elaborate on the present application in conjunction with the attached

[0032] An embodiment of the present application discloses a construction device for a horizontal drill for advanced geological prediction of a small-section tunnel in a water conservancy project. Referring to Figure 1 and Figure 2 , the construction device for the horizontal drill for advanced geological prediction of the small-section tunnel in the water conservancy project includes a vehicle body 1, an installation platform 2, and a drilling rig 3. Among them, the installation platform 2 includes a fixed seat 201, a rotating seat 202, an adjusting seat 203, and a mounting seat 204. The drilling rig 3 is arranged on the mounting seat 204, the mounting seat 204 is arranged on the adjusting seat 203, the adjusting seat 203 is arranged on the rotating seat 202, and the rotating seat 202 is arranged on the fixed seat 201.

[0033] Continuing to refer to Figure 1 and Figure 2, specifically, the fixed seat 201 is fixedly installed on the vehicle body 1, and the rotating seat 202 is rotatably installed on the fixed seat 201. The rotating seat 202 is in the shape of a rectangular plate. In the embodiment of the present application, the width direction of the rotating seat 202 is the x-axis direction, and the length direction is the y-axis direction. The fixed seat 201 is provided with a rotating mechanism for driving the rotating seat 202 to rotate. The rotating mechanism includes a rotating shaft 4, a rotating motor 5, and a commutation component. Among them, the rotating shaft 4 is horizontally fixedly installed on the rotating seat 202, the rotating shaft 4 is arranged along the x-axis direction, and the rotating shaft 4 horizontally penetrates and is rotatably installed on the fixed seat 201. The rotating motor 5 is installed on the fixed seat 201. The commutation component includes a worm wheel 6 and a worm 7. Among them, the worm 7 is fixedly installed on the output end of the rotating motor 5 and is rotatably installed on the fixed seat 201. The worm wheel 6 is coaxially fixedly installed on the rotating shaft 4 and meshes with the worm 7. When the rotating motor 5 drives the worm 7 to rotate, the worm wheel 6 drives the rotating shaft 4 and the rotating seat 202 to rotate together around the x-axis.

[0034] Referring to Figure 2 , to further ensure the stability of the rotating seat 202 during rotation, the rotating seat 202 is installed with a rotating guide block 8. Specifically, the rotating guide block 8 includes a guide fixing part 801 and a guide roller 802. The guide fixing part 801 is fixedly installed on the rotating seat 202, and the guide roller 802 is rotatably installed on the guide fixing part 801. The fixed seat 201 is provided with a rotating guide groove 9 arranged in an arc shape. The guide roller 802 is in rolling fit in the rotating guide groove 9. When the rotating seat 202 rotates around the axis of the rotating shaft 4, that is, the x-axis, the guide roller 802 rolls in the rotating guide groove 9 to play a limiting role in the rotation of the rotating seat 202. At the same time, the friction between the rotating guide block 8 and the rotating guide groove 9 during the rotation of the rotating seat 202 is small, which is beneficial to ensuring the service life of the rotating guide block 8.

[0035] Continue to refer to Figure 2, the adjusting seat 203 is slidably fitted to the rotating seat 202 in the x-axis direction. The rotating seat 202 is provided with a first motion mechanism. Specifically, the first motion mechanism includes an x-axis motion motor 10 and an x-axis motion lead screw 11. Among them, the x-axis motion motor 10 is installed on the rotating seat 202, the x-axis motion lead screw 11 is fixedly installed at the output end of the x-axis motion motor 10, the x-axis motion lead screw 11 passes through the adjusting seat 203 and is in threaded cooperation with the adjusting seat 203. When the x-axis motion motor 10 drives the x-axis motion lead screw 11 to rotate, the adjusting seat 203 drives the drilling rig 3 to move in the x-axis direction due to the threaded cooperation with the x-axis motion lead screw 11 and under the limiting action of the rotating seat 202. The setting of the x-axis motion lead screw 11 is beneficial to ensuring the stability when the drilling rig 3 is horizontally adjusted in the x-axis direction. To further ensure the stability of the adjusting seat 203 when moving in the x-axis direction, the rotating seat 202 is fixedly installed with an x-axis guide rod 12, and the x-axis guide rod 12 passes through and is slidably fitted to the adjusting seat 203 in the x-axis direction to play a further limiting role on the adjusting seat 203.

[0036] Refer to Figure 1 and Figure 2 , the adjusting seat 203 is provided with a second motion mechanism. The second motion mechanism includes a y-axis telescopic cylinder 13 arranged along the y-axis. Among them, the cylinder body of the y-axis telescopic cylinder 13 is fixedly installed on the adjusting seat 203, and the piston rod of the y-axis telescopic cylinder 13 is fixedly installed on the mounting seat 204, so that when the y-axis telescopic cylinder 13 drives its own piston rod to move, it drives the mounting seat 204 to move in the y-axis direction. The y-axis telescopic cylinder 13 is selected as a hydraulic cylinder in the embodiment of the present application, so that the y-axis telescopic cylinder 13 can drive a large stable bearing capacity, and at the same time is beneficial to ensuring the movement stability of the y-axis telescopic cylinder 13 driving its own piston rod. To further ensure the stability of the mounting seat 204 when moving in the y-axis direction, the mounting seat 204 is fixedly installed with a mounting guide block 14, and the top of the adjusting seat 203 is provided with a mounting guide groove 15 extending along the y-axis direction, and the mounting guide block 14 is slidably fitted in the mounting guide groove 15 to play a limiting role on the mounting seat 204 when sliding in the y-axis direction.

[0037] The implementation principle of the construction device of the advanced geological prediction horizontal drill for small-section tunnels in a water conservancy project in an embodiment of the present application is as follows: During the tunnel construction process, when the drill rig 3 drives its own drill pipe to rotate, the installation seat 204 is driven to move in the y-axis direction through the y-axis telescopic cylinder 13, thereby realizing the drilling construction of the drill rig 3; the rotation of the x-axis movement screw rod 11 is driven by the x-axis movement motor 10, so that the adjustment seat 203 drives the installation seat 204 and the drill rig 3 to adjust the position in the y-axis direction together, thereby facilitating the construction of the tunnel by the drill rig 3 at different horizontal positions on the y-axis; the rotation of the worm 7 is driven by the rotation motor 5, so that the worm gear 6 drives the rotating shaft 4, the rotating seat 202, the adjustment seat 203 and the installation seat 204 to rotate around the x-axis together, thereby facilitating the drill rig 3 to perform drilling treatment on more different positions of the tunnel at different angles, with strong applicability and convenient and fast operation for drilling construction at different positions of the tunnel.
