Description

Technical Field

[0001] This invention relates to the field of open-pit mine drilling technology, and in particular to an open-pit mine drilling positioning device. Background Technology

[0002] Open-pit mining involves stripping away the topsoil and surrounding rock of the ore body, transporting waste rock to a spoil heap, and directly extracting ore from the exposed ore body. Drilling and blasting is the most crucial step in the open-pit mining process. The quality of drilling and blasting directly impacts the overall production of the open-pit mine. The layout of borehole locations is the first step before drilling; the accuracy of the borehole location is a major factor in whether the drilling rig can operate according to the design. Therefore, the layout of borehole locations is particularly important in open-pit mining, as drilling and blasting requires the placement of a large number of boreholes in the ore body.

[0003] Patent document CN220136352U discloses an open-pit mine drilling positioning device, which includes an installation body and a support component installed on the installation body. The support component can be used to support the installation body. The positioning component is installed on the installation body by means of a ball. The positioning component can mark the location on the ground. The ball can adjust the verticality of the positioning component to the ground.

[0004] The above-mentioned technical solutions can only mark a single location at a time during positioning, resulting in low efficiency. Furthermore, the locking mechanism relies solely on the engagement of the top screw, which is prone to loosening and thus affects positioning accuracy. Therefore, we propose an open-pit mine drilling positioning device to solve this problem. Summary of the Invention

[0015] Preferably, an arc-shaped frame is fixedly installed at the bottom of the mounting frame, and an annular guide rail is fixedly installed at the top of the adjusting ring, with the arc-shaped frame slidably sleeved on the outside of the annular guide rail;

[0016] An external gear ring is fixedly sleeved on the outer side of the mounting ring, a servo motor is fixedly mounted on the top of the adjusting ring, and a drive gear is fixedly mounted on the output shaft of the servo motor. The drive gear meshes with the external gear ring.

[0017] Preferably, a limiting ring is fixedly installed at the bottom of the sliding seat, and the limiting ring movably abuts against the outside of the connecting ball. A connecting rod is fixedly installed on the output end of the electric push rod, and multiple positioning grooves are opened on the outside of the connecting rod. A guide frame is fixedly installed at the top of the fixed ring, and the guide frame is slidably sleeved on the outside of the connecting rod.

[0018] Preferably, an electromagnet is fixedly installed at the bottom of the side plate, an iron plate is fixedly installed at the top of the connecting ring, the iron plate and the electromagnet are magnetically attracted to each other, a connecting spring is fixedly installed at the bottom of the connecting ring, and the bottom end of the connecting spring is fixedly installed at the top of the fixed ring.

[0019] Preferably, multiple levels are fixedly installed on the top of the adjusting ring, and a controller is fixedly installed on the bottom of the adjusting ring. The controller has signal connections to the levels and electric push rods. Three support columns are fixedly installed on the bottom of the fixed ring. A lifting plate is slidably sleeved on the outer side of the support columns. A caster wheel is fixedly installed on the bottom of the lifting plate. Three cylinders are fixedly installed on the top of the fixed ring, and the output end of the cylinder is fixedly installed on the top of the corresponding lifting plate.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. In this invention, an open-pit mine drilling positioning device is described. A starting cylinder drives a lifting plate downwards, bringing the casters into contact with the ground, thus facilitating the movement of the device to the work area. Then, the starting cylinder controls the lifting plate to rise, bringing the support column into contact with the ground. An electromagnet is activated, generating magnetism, which in turn attracts the iron sheet, causing the connecting ring to move upwards. The vertical plate and linkage plate work together to move the positioning pin outwards, disengaging it from the positioning slot. Next, the controller activates the electric push rod. When the ground tilts, both the fixed ring and the adjusting ring tilt accordingly, while the column remains vertical under the action of the counterweight plate. This allows the column to contact the touch button on the lower side of the ground, controlling the output end of the corresponding electric push rod to extend. The connecting ball, sliding seat, and slide rail work together to move the lower side of the adjusting ring upwards. Once the column and the three touch buttons are no longer pressed together, the electric push rod stops working, thus achieving rough leveling.

[0022] 2. In this invention, the open-pit mine drilling positioning device detects the horizontal state of the adjusting ring by activating multiple levels and transmits the signal to the controller. The controller then controls the corresponding electric push rod to start until all levels detect that the adjusting ring is horizontal. Next, the electric push rod stops operating and the electromagnet is de-energized, causing the connecting ring to move downward under the action of the connecting spring. The vertical plate and the linkage rod drive the positioning pin to insert into the positioning groove, thereby locking the connecting rod and locking the horizontal state of the adjusting ring.

[0023] 3. In this invention, the open-pit mine drilling positioning device, by starting a drive motor to drive a bidirectional screw to rotate, the bidirectional screw, through its threaded engagement with two sliding plates, causes the two sliding plates to move away from each other, thereby adjusting the distance between the marking cylinder and the mounting frame. Next, a servo motor is started to drive a drive gear to rotate, and the drive gear, through meshing with an external gear ring, causes the mounting ring and mounting frame to rotate, thereby causing the marking cylinder to perform circular motion, facilitating the movement of the marking cylinder to a designated position. Then, a rotary motor is started to drive a drive gear to rotate slowly, and the drive gear, through meshing with a driven gear, causes the marking cylinder to rotate. Simultaneously, the rotation of the marking cylinder, through the engagement of the positioning ring and the vertical rod, causes... The piston plate rotates synchronously, driving the lead screw to rotate. The lead screw rotates and moves downwards while engaging with the threaded sleeve, thereby squeezing the ink pre-stored in the marking head from the outlet nozzle, causing the ink to drip onto the ground and form a mark. Since the marking head rotates while spraying ink, the sprayed ink can form a ring mark on the ground, which is convenient for subsequent drilling positioning. The marking cylinder can be moved to another position by the cooperation of the servo motor and the drive motor, and the above steps can be repeated to achieve marking at different positions. Since the adjusting ring is fixed to a horizontal position while marking, there is no need to readjust the marking cylinder.

[0024] 4. In this invention, the open-pit mine drilling positioning device can achieve automatic leveling through the combination of the set adjustment mechanism, touch button and level. Through the combination of the set marking cylinder, servo motor and drive motor, multi-point marking can be performed after a single leveling, improving positioning efficiency. And by controlling the rotation of the marking head to achieve ink injection, a ring mark can be formed, thereby improving positioning accuracy. Attached Figure Description

A connecting rod 8 is fixedly installed on the output end of the electric push rod 7. Multiple positioning grooves are opened on the outside of the connecting rod 8. A guide frame 801 is fixedly installed at the top of the fixing ring 1. The guide frame 801 is slidably sleeved on the outside of the connecting rod 8. A guide plate 803 and a side plate 810 are fixedly installed on the outside of the guide frame 801. A positioning pin 802 is slidably installed in the guide plate 803. The positioning pin 802 is movably inserted into the corresponding positioning groove. A vertical plate 805 is slidably installed in the side plate 810. A linkage rod 804 is hinged between the vertical plate 805 and the positioning pin 802. The bottom of multiple vertical plates 805 is fixedly installed with the same connecting ring 806.

[0050] In this embodiment, an electromagnet 809 is fixedly installed at the bottom of the side plate 810, and an iron plate 808 is fixedly installed at the top of the connecting ring 806. The iron plate 808 and the electromagnet 809 are magnetically attracted to each other. A connecting spring 807 is fixedly installed at the bottom of the connecting ring 806. The bottom end of the connecting spring 807 is fixedly installed at the top of the fixing ring 1, thereby resetting the connecting ring 806.

[0051] In this embodiment, multiple levels 9 are fixedly installed on the top of the adjusting ring 2, and a controller 10 is fixedly installed on the bottom of the adjusting ring 2. The controller 10 is connected to the levels 9 and the electric push rod 7. Three support columns 101 are fixedly installed on the bottom of the fixed ring 1. A lifting plate 103 is slidably sleeved on the outer side of the support column 101. A caster wheel 102 is fixedly installed on the bottom of the lifting plate 103. Three cylinders 104 are fixedly installed on the top of the fixed ring 1. The output end of the cylinder 104 is fixedly installed on the top of the corresponding lifting plate 103.

[0052] In this embodiment, during use, the lifting plate 103 is moved downward by the starting cylinder 104, so that the caster wheel 102 contacts the ground, thus facilitating the movement of the device to the work area. Then, the lifting plate 103 is raised by the starting cylinder 104, so that the support column 101 contacts the ground. The electromagnet 809 is activated, causing it to generate magnetism. Through the magnetic attraction of the iron plate 808, the connecting ring 806 moves upward. The positioning pin 802 moves outward through the cooperation of the vertical plate 805 and the linkage plate, so that the positioning pin 802 disengages from the positioning groove. Then, the electric push rod 7 is activated by the controller 10. When the ground tilts, the fixed ring 1 and the adjusting ring 2 will tilt accordingly, while the column 601 is counterweighted. The plate 6 keeps the plate vertical, causing the column 601 to contact the touch button 11 on the lower side of the plate. This controls the output end of the corresponding electric push rod 7 to extend, thereby causing the lower side of the adjusting ring 2 to move upward through the cooperation of the connecting ball 701, the sliding seat 703, and the slide rail 704. When the column 601 and the three touch buttons 11 are no longer pressed together, the electric push rod 7 stops working, thus achieving rough leveling. Multiple levels 9 are activated to detect the level of the adjusting ring 2 and transmit the signals to the controller 10. The controller 10 then controls the corresponding electric push rod 7 to start until all levels 9 detect that the adjusting ring 2 is level. Finally, the electric push rod 7 stops operating and the electromagnet 8 is activated. 09. Power is cut off, causing the connecting ring 806 to move downward under the action of the connecting spring 807. This, along with the vertical plate 805 and the linkage rod 804, drives the positioning pin 802 to insert into the positioning groove, locking the connecting rod 8 and thus locking the adjusting ring 2 to its horizontal position. The drive motor 402 is then activated, driving the bidirectional screw 401 to rotate. The bidirectional screw 401, through its threaded engagement with the two sliding plates 4, moves the two sliding plates 4 away from each other, thus adjusting the distance between the marking cylinder 5 and the mounting frame 3. Next, the servo motor 304 is activated, driving the drive gear 303 to rotate. The drive gear 303, through its meshing with the external gear ring 302, drives the mounting ring 301 and the mounting frame 3 to rotate, thereby causing the marking cylinder 5 to perform a circular motion, facilitating the movement of the marking cylinder 5. Once the device moves to the designated position, the rotary motor 511 is activated, driving the drive gear 510 to rotate slowly. The drive gear 510, through meshing with the driven gear 509, drives the marking cylinder 5 to rotate. Simultaneously, the marking cylinder 5 rotates, and through the engagement of the positioning ring 506 and the vertical rod 505, it drives the piston plate 503 to rotate synchronously. The piston plate 503 drives the lead screw 504 to rotate. The lead screw 504, through its threaded engagement with the threaded sleeve 507, rotates and moves downwards, thereby squeezing the ink pre-stored in the marking head 501 from the dispensing nozzle 502, causing the ink to drip onto the ground, forming a mark. Because the marking head 501 rotates while spraying ink, the sprayed ink forms a ring-shaped mark on the ground, facilitating subsequent drilling positioning.Furthermore, the marking cylinder 5 can be moved to another position through the cooperation of the servo motor 304 and the drive motor 402, and the above steps can be repeated to achieve marking at different positions. Since the adjusting ring 2 is already fixed in a horizontal position during marking, there is no need to readjust the marking cylinder 5.
