Description

Technical Field

[0001] This application relates to the field of drilling technology, and in particular to a device for controlling the verticality of drilling. Background Technology

[0002] In geological exploration and construction engineering, drilling is a crucial step in obtaining underground geological data and carrying out construction. The quality of the borehole directly affects the smooth progress of subsequent work. For example, in mineral resource exploration, the verticality of the borehole determines the integrity and representativeness of the ore core, while in construction engineering, the precision of the borehole is related to the stability and safety of the building.

[0003] Currently, most drilling rigs on the market lack effective verticality control devices during drilling operations. In the design of traditional drilling rigs, there are no fixing or limiting devices around the drill bit and drill rod, allowing the drill bit to rotate freely, resulting in a hole diameter much larger than the drill bit diameter.

[0004] This results in the drill bit tending to deviate towards the softer surrounding strata when drilling into larger particles such as medium sand, coarse sand, and gravel layers during actual construction, making it difficult to effectively control the verticality of the borehole. Utility Model Content

[0005] The purpose of this application is to solve the problem that, during actual construction, when drilling rigs encounter strata with larger particles, such as medium sand, coarse sand, and gravel layers, the drill bit tends to deviate towards the surrounding softer strata, thus making it impossible to effectively control the verticality of the borehole. This application provides a device for controlling the verticality of the drilling rig.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A device for controlling the verticality of a drilling rig includes a tracked vehicle. A guide frame is hinged to one end of the tracked vehicle, and an electric actuator is also hinged to one end of the tracked vehicle. A follower slide groove is symmetrically formed at one end of the guide frame. A follower slider is slidably connected inside the follower slide groove. The output end of the electric actuator is hinged to the follower slider. A verticality sensor is fixedly connected to one end of the guide frame. A lifting slide groove is formed at one end of the guide frame. A lifting slide is slidably connected inside the lifting slide groove. A drilling rig body is rotatably connected to one end of the lifting slide. A base is fixedly connected to the bottom of the guide frame. A guide hole adapted to the drilling rig body is formed at one end of the base. A lifting assembly for driving the lifting slide to move along the length of the lifting slide groove is installed at one end of the guide frame. A fixing assembly for clamping one end of the drilling rig body is installed inside the guide hole.

[0008] By adopting the above technical solution, and by setting up the lifting component and the fixing component in cooperation, it is convenient to use a verticality sensor to monitor the drilling verticality of the drilling machine body in real time when the starting electric actuator pushes the follower slider to push the guide frame to rotate around the hinge axis to a state perpendicular to the ground. At the same time, when one end of the drilling machine body is driven to pass through the guide hole and drill into the ground, the fixing component is used to clamp and limit one end of the drilling machine body to improve the drilling accuracy of the drilling machine body. This facilitates the monitoring and guidance and limiting of the vertical angle of the drilling machine body, effectively reducing the situation where the drilling machine body deviates during drilling and affects the drilling verticality, thus improving the accuracy of the device.

[0009] Furthermore, the lifting assembly includes a lifting screw rotatably connected inside the lifting slide groove, the lifting screw being threadedly connected to one end of the lifting slide, and a lifting motor being fixedly connected to one end of the guide frame, the output end of the lifting motor being fixedly connected to the lifting screw.

[0010] By adopting the above technical solution, and by setting up the cooperation between the lifting screw and the lifting motor, the starting of the lifting motor can drive the lifting screw to form a threaded connection with the lifting slide, and drive the lifting slide to move the drilling machine body along the length of the lifting slide, which effectively improves the practicality of the device.

[0011] Furthermore, the fixing assembly includes a pair of fixing grooves symmetrically opened inside the guide hole, a fixing rod is slidably connected inside the fixing groove, an arc-shaped clamp is fixedly connected to one end of two adjacent fixing rods, an electric actuator is symmetrically fixedly connected to one end of the base, the output end of the electric actuator is fixedly connected to the arc-shaped clamp, and an abutment is installed at one end of the arc-shaped clamp.

[0012] By adopting the above technical solution, and by setting up the cooperation between the abutment and the electric actuator and the arc-shaped clamp, when one end of the drilling machine body passes through the guide hole and drills into the ground, the electric actuator is activated to drive the arc-shaped clamp to push the abutment and the drilling machine body to form a rolling abutment, thereby realizing the rolling clamping of the drilling machine body, effectively improving the stability of the drilling machine body when drilling into the ground, and further reducing the occurrence of deviation of the drilling machine body.

[0013] Furthermore, the abutting element includes a plurality of abutting balls that are uniformly spherically hinged to opposite sides of the two arc-shaped clamps.

[0014] By adopting the above technical solution, and by setting the contact ball and the arc-shaped clamping plate to work together, the arc-shaped clamping plate forms a rolling contact with the drilling machine body through the contact ball, which effectively reduces the wear between the arc-shaped clamping plate and the drilling machine body and extends the service life of the device.

[0015] Furthermore, a positioning rod is symmetrically hinged to one end of the base, and a positioning groove is provided at one end of the positioning rod. A positioning fork is inserted into the positioning groove, and a limit component is installed at one end of the positioning fork.

[0016] By adopting the above technical solution, and by setting the limit component in conjunction with the positioning groove and positioning fork, it is easy to rotate the positioning rod around the hinge axis to separate it from both sides of the base for unfolding. Then, one end of the positioning fork is pulled through the positioning groove and inserted into the ground to improve the connection strength between the base and the ground, making the drilling of the drilling machine body more stable and maintaining the vertical accuracy of the drilling machine body.

[0017] Furthermore, the limiting component includes a limiting block fixedly connected to one end of the positioning fork, and one end of the positioning rod has a limiting hole adapted to the limiting block.

[0018] By adopting the above technical solution, and by setting the limit block and the limit hole to work together, when one end of the traction positioning fork passes through the positioning groove and is inserted into the ground, the positioning fork drives the limit block to be inserted into the inside of the limit hole, thereby effectively improving the connection strength between the positioning fork and the positioning rod and improving the stability of the device.

[0019] Furthermore, one end of the base is symmetrically and fixedly connected with a storage screw adapted to the positioning groove, and one end of the storage screw is threadedly connected with a storage nut.

[0020] By adopting the above technical solution, and by setting up the cooperation of the storage screw and the storage nut, it is convenient to tighten the storage nut when the positioning rod rotates around the hinge axis and drives the positioning groove to fit one end of the storage screw. This allows the storage nut to push the positioning rod and the base to form a fixed connection along the length of the storage screw, thus facilitating the fixed connection between the positioning rod and the base.

[0021] Furthermore, a counterweight is fixedly connected to the end of the tracked vehicle away from the guide frame.

[0022] By adopting the above technical solution and using counterweights in conjunction with the tracked vehicle, the stability of the tracked vehicle is effectively improved.

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

[0024] 1. By using the lifting and fixing components in conjunction, when the electric actuator pushes the follower slider to rotate the guide frame around the hinge axis to a perpendicular position to the ground, the verticality sensor can monitor the drilling verticality of the drilling machine body in real time. At the same time, when one end of the drilling machine body passes through the guide hole and drills into the ground, the fixing component clamps and limits one end of the drilling machine body to improve the drilling accuracy. This facilitates the monitoring and guiding of the vertical angle of the drilling machine body, effectively reducing the deviation of the drilling machine body during drilling and affecting the drilling verticality, thus improving the accuracy of the device.

[0025] 2. By setting the limit component and using the positioning groove and positioning fork together, it is easy to rotate the positioning rod around the hinge axis to separate it from the two sides of the base and unfold it. Then, one end of the positioning fork is pulled through the positioning groove and inserted into the ground to improve the connection strength between the base and the ground, making the drilling of the drilling machine body more stable and maintaining the vertical accuracy of the drilling machine body.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a device for controlling the verticality of drilling holes.

[0034] Reference Figures 1-3 A device for controlling the verticality of drilling rigs includes a tracked vehicle 1, a guide frame 2 hinged to one end of the tracked vehicle 1, and an electric push rod 3 hinged to one end of the tracked vehicle 1. A follower slide groove 4 is symmetrically opened on one end of the guide frame 2. A follower slider 5 is slidably connected inside the follower slide groove 4. The output end of the electric push rod 3 is hinged to the follower slider 5. A verticality sensor 6 is fixedly connected to one end of the guide frame 2. A lifting slide groove 7 is opened on one end of the guide frame 2. A lifting slide 8 is slidably connected inside the lifting slide groove 7. A drilling machine body 9 is rotatably connected to one end of the lifting slide 8. A base 10 is fixedly connected to the bottom of the guide frame 2. A guide hole 11 adapted to the drilling machine body 9 is opened at one end of the base 10. A lifting component for driving the lifting slide 8 to move along the length direction of the lifting slide groove 7 is installed at one end of the guide frame 2. A fixing component for clamping one end of the drilling machine body 9 is installed inside the guide hole 11.

[0035] The lifting assembly includes a lifting screw 12 rotatably connected inside the lifting slide 7. The lifting screw 12 is threadedly connected to one end of the lifting slide 8. A lifting motor 13 is fixedly connected to one end of the guide frame 2. The output end of the lifting motor 13 is fixedly connected to the lifting screw 12.

[0036] In operation, the tracked vehicle 1 is first started, moving the drilling machine body 9 to the drilling area. The electric actuator 3 is then activated, pushing the follower slider 5 around the hinge shaft. Simultaneously, the follower slider 5 is pushed to contact the guide frame 2, causing it to push the guide frame 2 to rotate around the hinge shaft until it is perpendicular to the tracked vehicle 1, while sliding along the length of the follower groove 4. At the same time, the verticality sensor 6 monitors the perpendicularity of the drilling machine body 9 to the ground. When the drilling machine body 9 is perpendicular to the ground, the lifting motor 13 is activated, driving the lifting screw 12 to rotate. This causes the lifting screw 12 to form a threaded connection with the lifting slide table 8, thereby causing the lifting slide table 8 to drive the drilling machine. The drilling machine body 9 moves towards the ground along the length of the lifting slide 7. Simultaneously, by activating the drilling machine body 9, it moves towards the ground along the length of the lifting slide 7 while passing through the guide hole 11 to rotate and drill a hole in the ground. Then, when one end of the drilling machine body 9 passes through the tracked vehicle 1 and drills into the ground, the fixing component is activated to clamp and fix one end of the drilling machine body 9, thereby reducing the possibility of the drilling machine body 9 deviating when drilling into the ground. This facilitates the monitoring and guidance of the vertical angle of the drilling machine body 9, effectively reducing the possibility of the drilling machine body 9 deviating during drilling and affecting the verticality of the hole, thus improving the accuracy of the device.

[0037] Reference Figures 2-4The fixing component includes a pair of fixing grooves 14 symmetrically opened inside the guide hole 11. The fixing grooves 14 are slidably connected to the fixing rods 15. One end of the two adjacent fixing rods 15 is fixedly connected to an arc-shaped clamping plate 16. One end of the base 10 is symmetrically fixedly connected to an electric actuator 17. The output end of the electric actuator 17 is fixedly connected to the arc-shaped clamping plate 16. One end of the arc-shaped clamping plate 16 is equipped with an abutment.

[0038] The contact element includes a plurality of contact balls 18 that are uniformly ball-hinged to the opposite sides of two arc-shaped clamps 16.

[0039] In use, when one end of the drilling machine body 9 passes through the guide hole 11 and drills into the ground, the two electric actuators 17 are activated, causing the electric actuators 17 to push the arc-shaped clamping plate 16 to move the fixed slide bar 15 along the length of the fixed slide groove 14. At the same time, the two arc-shaped clamping plates 16 drive the contact ball 18 to move closer to each other along the length of the fixed slide groove 14. The arc-shaped clamping plates 16 push the contact ball 18 to form a rolling contact with one end of the drilling machine body 9. The two arc-shaped clamping plates 16 also form a rolling clamping of the drilling machine body 9 passing through the guide hole 11 along the length of the fixed slide groove 14, which effectively improves the stability of the drilling machine body 9 when drilling into the ground and further reduces the possibility of the drilling machine body 9 deviating.

[0040] Reference Figures 1-3 One end of the base 10 is symmetrically hinged with a positioning rod 19, one end of the positioning rod 19 is provided with a positioning groove 20, a positioning fork 21 is inserted inside the positioning groove 20, and a limit component is installed at one end of the positioning fork 21.

[0041] The limiting component includes a limiting block 22 fixedly connected to one end of the positioning fork 21, and a limiting hole 23 adapted to the limiting block 22 is provided at one end of the positioning rod 19.

[0042] Furthermore, one end of the base 10 is symmetrically and fixedly connected with a storage screw 24 that is adapted to the positioning groove 20, and one end of the storage screw 24 is threadedly connected with a storage nut 25.

[0043] When in use, when the electric actuator 3 pushes the guide frame 2 to rotate the drilling machine body 9 around the hinge axis until it is perpendicular to the ground, the fixed connection between the positioning rod 19 and the base 10 is released by manually loosening the storage nut 25. Then, the positioning rod 19 is rotated around the hinge axis to unfold, and the positioning fork 21 is inserted into the positioning groove 20 by pulling. Then, one end of the positioning fork 21 is inserted into the ground by using a hammer or other tools. At the same time, the positioning fork 21 drives the limiting block 22 to embed into the limiting hole 23, thereby improving the connection strength between the positioning fork 21 and the positioning rod 19. This effectively improves the connection stability between the base 10 and the ground, and further improves the vertical accuracy of the drilling machine body 9.

[0044] Then, when the positioning rod 19 is not needed, the positioning rod 19 is manually rotated around the junction shaft to be stored on both sides of the base 10. At the same time, the positioning rod 19 drives the positioning groove 20 to be sleeved on one end of the storage screw 24. Then, the storage nut 25 is tightened so that the storage nut 25 forms a fixed contact with the positioning rod 19 along the length direction of the storage screw 24. This facilitates the quick storage of the positioning rod 19 and effectively improves the practicality of the device.

[0045] Reference Figure 1 and Figure 2 A counterweight 26 is fixedly connected to the end of the tracked vehicle 1 away from the guide frame 2.

[0046] In use, the counterweight 26 effectively increases the weight of the tracked vehicle 1, which in turn improves the stability of the tracked vehicle 1 when the drilling machine body 9 transmits the impact force generated during drilling to the tracked vehicle 1, thereby further improving the drilling stability of the drilling machine body 9.

[0047] The implementation principle of the device for controlling the verticality of drilling in this embodiment is as follows: First, the tracked vehicle 1 is started to move the drilling machine body 9 to the drilling area, and the electric push rod 3 is started to push out the follower slider 5 around the hinge axis. At the same time, the follower slider 5 is pushed to form an abutment with the guide frame 2, so that the follower slider 5 pushes the guide frame 2 to rotate around the hinge axis to a state perpendicular to the tracked vehicle 1, and slides along the length direction of the follower slide groove 4. At the same time, the verticality sensor 6 is started to monitor the verticality of the drilling machine body 9 with the ground. When the drilling machine body 9 is perpendicular to the ground, the fixed connection between the positioning rod 19 and the base 10 is released by manually loosening the storage nut 25. Then, the positioning rod 19 is rotated around the junction axis to unfold, and the positioning fork 21 is inserted into the positioning groove 20 by pulling. Then, a hammer or other tools are used to insert one end of the positioning fork 21 into the ground, so that the positioning fork 21 drives the limiting block 22 to embed into the limiting hole 23, thereby improving the connection strength between the positioning fork 21 and the positioning rod 19, thereby effectively improving the connection stability between the base 10 and the ground.

[0048] Then, by starting the lifting motor 13, the lifting screw 12 is driven to rotate, and the lifting screw 12 is driven to form a threaded connection with the lifting slide 8, so that the lifting slide 8 drives the drilling machine body 9 to move towards the ground along the length direction of the lifting slide 7. At the same time, by starting the drilling machine body 9, the drilling machine body 9 moves towards the ground along the length direction of the lifting slide 7 while passing through the guide hole 11 to rotate and drill a hole in the ground.

[0049] Simultaneously, when one end of the drilling machine body 9 passes through the tracked vehicle 1 and drills into the ground, by activating the two electric push rods 17, the electric push rods 17 push the arc-shaped clamping plate 16 to drive the fixed slide rod 15 to move along the length direction of the fixed slide groove 14. At the same time, the two arc-shaped clamping plates 16 drive the contact ball 18 to move closer to each other along the length direction of the fixed slide groove 14. At the same time, the arc-shaped clamping plates 16 push the contact ball 18 to form a rolling contact with one end of the drilling machine body 9. At the same time, the two arc-shaped clamping plates 16 form a rolling clamping of the drilling machine body 9 passing through the guide hole 11 along the length direction of the fixed slide groove 14.

[0050] Next, when the positioning rod 19 is not needed, the positioning rod 19 is manually rotated around the junction shaft to be stored on both sides of the base 10. At the same time, the positioning rod 19 drives the positioning groove 20 to be sleeved on one end of the storage screw 24. Then, the storage nut 25 is tightened so that the storage nut 25 forms a fixed contact with the positioning rod 19 along the length direction of the storage screw 24, so as to realize the storage of the positioning rod 19.
