Description

Technical Field

[0001] The utility model relates to the technical field of rock drill testing, and in particular to a rock drill trolley arm drilling function testing device. In addition, the utility model also relates to a rock drill testing system including the rock drill trolley arm drilling function testing device. Background Art

[0002] When drilling inside the rock, the rock drill fully breaks the rock by impacting the rock surface with high frequency and continuously rotating at a small angle. Therefore, the drill bit is mainly subjected to the axial thrust load of the rock surface and the circumferential rotation load of the hole wall.

[0003] At present, some companies have independently designed and used some devices that can simulate the resistance and friction encountered by rock drills during drilling. That is, the circumferential rotational load is simulated through the gearbox and hydraulic motor, and the axial thrust load is simulated through the cylinder. However, in the existing design, the drill rod needs to pass through the freely rotating hexagonal hole in the gearbox. In order to effectively drive the drill rod to rotate, the size of the hexagonal hole is almost the same as the drill rod. Due to the low control accuracy of the rock drilling rig boom actuator, the cylinder and motor, it is often very difficult for the drill rod to pass through the hexagonal hole. In addition, because the drill rod will reciprocate back and forth in a small amplitude during high-frequency impact, the drill rod and the hole are easily worn, and the gap between the two becomes larger, affecting the rotation function.

[0004] On the other hand, in terms of propulsion load simulation, the free end of the impact cylinder piston rod in the existing equipment is directly impacted by the drill pipe, which places high demands on the rod strength and connection strength of the cylinder piston rod. Moreover, once the piston rod is deformed and damaged, the replacement cost and time will seriously restrict the economic efficiency of the equipment. Utility Model Content

[0005] The utility model provides a rock drilling rig arm drilling function test device and a rock drill test system, which solve the technical problem of the difficulty in connecting the gear box and the drill rod of the existing rock drill test equipment.

[0006] According to one aspect of the present invention, a drilling function test device for a drilling rig boom is provided, comprising:

[0007] a rack, used as a structural support;

[0008] a propulsion load simulation mechanism, mounted on the frame, for applying an axial load to the drill rod of the target rock drill under test to simulate the axial resistance during drilling;

[0009] a rotary load simulation mechanism, mounted on the frame, comprising a driver, a transmission box, a mobile platform, and a mobile assembly, wherein the transmission box is mounted on the mobile platform via the mobile assembly, and the mobile platform is axially slidably connected to the frame, the mobile assembly being configured to move and adjust the position of the transmission box in a plane perpendicular to the axial direction of the test device so that the transmission box can dock with the drill rod, and the driver being configured to apply a rotary load to the drill rod of the target rock drill via the transmission box;

[0010] The vibration absorbing mechanism is installed on the frame and is arranged between the output end of the propulsion load simulation mechanism and the rotation load simulation mechanism, and is used to reduce the impact load on the reverse thrust mechanism caused by the high-frequency impact of the drill rod.

[0011] As a further improvement of the above technical solution, the output shaft of the driver extends into the transmission box, and the transmission box includes an output gear arranged on the output shaft of the driver, a central shaft passing through the transmission box, and a main gear arranged on the central shaft and meshing with the output gear. A connecting sleeve is provided at the first end of the central shaft for connecting to the drill rod, and an impact head is provided at the second end of the central shaft for cooperating with the vibration absorbing mechanism.

[0012] As a further improvement of the above technical solution, the moving assembly includes a transverse guide rail arranged on the frame, a longitudinal guide rail slidably connected to the transverse guide rail and used for installing the transmission box, and a locking mechanism for fixing the position of the transmission box.

[0013] As a further improvement of the above technical solution, the moving component also includes an adjusting mechanism, which includes a translating screw and a lifting screw arranged on the moving platform, a first screw sleeve threadedly connected to the translating screw is provided on the longitudinal guide rail, and a second screw sleeve threadedly connected to the lifting screw is provided on the transmission box.

[0014] As a further improvement of the above technical solution, the vibration absorbing mechanism includes a cylinder body, a hydraulic rod passing through the cylinder body, a piston head arranged at the first end of the hydraulic rod and cooperating with the inner cavity of the cylinder body, and a punch head arranged at the second end of the hydraulic rod.

[0015] As a further improvement of the above technical solution, the piston head divides the inner cavity of the cylinder into a rod cavity and a rodless cavity, and the cylinder includes an oil passage connecting the rod cavity and the rodless cavity, and a damper is provided in the oil passage.

[0016] As a further improvement of the above technical solution, internal teeth are provided in the middle of the main gear, and external teeth for meshing with the internal tooth grooves are provided on the outer wall of the central shaft.

[0017] As a further improvement of the above technical solution, the test device includes a hydraulic pump station and a controller. The hydraulic pump station is used to provide power to the vibration absorption mechanism and the propulsion load simulation mechanism respectively, and the controller is used to control the oil supply pressure and oil supply direction of the hydraulic pump station.

[0018] As a further improvement of the above technical solution, a limit switch electrically connected to the controller is provided on the frame, which is used to cut off or switch the oil supply of the hydraulic pump station to the propulsion load simulation mechanism when the mobile platform moves into place.

[0019] According to another aspect of the present invention, a rock drill testing system is provided, which includes the above-mentioned rock drilling rig boom drilling function testing device.

[0020] The utility model has the following beneficial effects:

[0021] Before starting the test, the rock drill to be tested is in place. This test device pushes the transmission box through the propulsion load simulation mechanism to make the mobile platform slide axially on the frame toward the rock drill. After the mobile platform is in place, the position of the transmission box is adjusted by the mobile component to align the center of its output axis with the drill rod, avoiding the drill rod with low operating control accuracy to align the hole, reducing the difficulty of operation while ensuring accurate hole alignment; after the hole is aligned, the propulsion load simulation mechanism and the vibration absorption mechanism are ready for testing, and the rock drill is started for testing. The drill rod drives the impact head to rotate and simultaneously impacts the vibration absorption mechanism at high frequency. The driver action applies a torque opposite to the drill rod's rotation through the rotary load simulation mechanism to simulate the rotary load on the drill rod. The propulsion load simulation mechanism applies an axial load to the drill rod of the target rock drill under test to simulate the axial resistance during the drilling process. The force, drill rod advancement speed and stroke are all controlled by the rock drill. Different parameters are set according to the test requirements. The drill rod pushes the mobile platform to move slowly in the axial direction, and at the same time, the load simulation mechanism is slowly retracted under the thrust of the drill rod. After the drill rod is advanced to the set distance, the rock drill stops impacting and advancing, and after reversing, it separates from the transmission box and returns to its initial position. The transmission box is connected to the end of the drill rod so that the rotary load is applied to the end of the drill rod, which is closer to the actual working condition. The vibration absorption mechanism and the thrust load simulation mechanism are separate mechanisms with low structural complexity, which reduces the manufacturing difficulty and cost, and is more convenient to maintain and replace. By setting the mobile component to adjust the position of the transmission box to match the drill rod, the docking operation steps are simplified, the docking time and difficulty are shortened, and the test efficiency is effectively improved.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0032] like Figures 1 to 4 As shown, the drilling function test device of the drilling rig boom of this embodiment includes:

[0033] a rack, used as a structural support;

[0034] A propulsion load simulation mechanism 1 is mounted on a frame and includes a reverse thrust cylinder. A sliding platform 12 is axially slidably connected to the frame and is used to support the end of the output end of the reverse thrust cylinder and to apply an axial load to the drill rod 5 of the target rock drill 7 under test to simulate the axial resistance during drilling.

[0035] A rotary load simulation mechanism 4 is mounted on the frame and includes a driver 402, a transmission box 401, a mobile platform 11, and a moving assembly. The transmission box 401 is mounted on the mobile platform 11 via the moving assembly. The mobile platform 11 is axially slidably connected to the frame. The moving assembly is used to move and adjust the position of the transmission box 401 in a plane perpendicular to the axial direction of the test device so that the transmission box 401 can dock with the drill rod 5. The driver 402 is mounted on the transmission box 401 and is used to apply a rotary load to the drill rod 5 of the target rock drill 7 via the transmission box 401.

[0036] The vibration absorbing mechanism 3 is mounted on the frame and disposed between the output end of the propulsion load simulation mechanism 1 and the rotary load simulation mechanism 4 , and is used to mitigate the impact load on the reverse thrust mechanism caused by the high-frequency impact of the drill rod 5 .

[0037] It should be understood that the rock drill 7 is conventional and includes a propulsion beam 8 and a drill rod 5. A support plate 6 is provided on the frame for cooperating with the propulsion beam 8. Before the test, the driver operates the rock drill 7 to press against the support plate 6, and the drill rod 5 is aligned with the through-hole on the support plate 6. The thrust of the propulsion load simulation mechanism 1 is applied to the drill rod 5 via the rotary load simulation mechanism 4.

[0038] Specifically, the driver 402 is a hydraulic motor. The output shaft 4014 of the driver 402 extends into the transmission case 401. The transmission case 401 includes an output gear 4013 disposed on the output shaft 4014 of the driver 402, a central shaft 4011 extending through the transmission case 401, and a main gear 4012 disposed on the central shaft 4011 and meshing with the output gear 4013. A connecting sleeve 410 is disposed at a first end of the central shaft 4011 for connecting to the drill rod 5. An impact head 416 is disposed at a second end of the central shaft 4011 for cooperating with the vibration absorbing mechanism 3.

[0039] The test device includes a hydraulic pump station 16 and a controller 15. The hydraulic pump station 16 is used to provide power to the vibration absorption mechanism 3, the rotary load simulation mechanism 4, and the propulsion load simulation mechanism 1 respectively. The controller 15 is used to control the oil supply pressure and oil supply direction of the hydraulic pump station 16.

[0040] The frame includes a first base 17 and a second base 10, both of which are fixed to the ground by anchor bolts. The first base 17 and the second base 10 are connected by a hinge mechanism 13. The propulsion load simulation mechanism 1 is installed on the first base 17 through the cylinder fixing base 2. The hydraulic pump station 16 is set on the first base 17. The slide rail 9 is set on the second base 10. The mobile platform 11 and the sliding platform 12 are both set on the slide rail 9 of the second base 10.

[0041] It can be understood that before starting the test, the rock drill 7 to be tested is in place, and the test device pushes the transmission box 401 through the propulsion load simulation mechanism 1 to make the mobile platform 11 slide axially on the frame toward the rock drill 7. After the mobile platform 11 is in place, the position of the transmission box 401 is adjusted by the mobile component to align the center of the output end axis with the drill rod 5, avoiding the drill rod 5 with low control accuracy to align the hole, reducing the difficulty of operation while ensuring accurate hole alignment; after the hole is aligned, the load simulation mechanism 1 and the vibration absorption mechanism 3 are pushed to prepare for the test, and the rock drill 7 is started for testing. The drill rod 5 drives the impact head 416 to rotate and simultaneously impacts the vibration absorption mechanism 3 at high frequency. The driver 402 acts to apply a torque opposite to the direction of the drill rod 5 through the rotary load simulation mechanism 4 to simulate the rotary load on the drill rod 5, and the load simulation mechanism 1 is pushed to apply an axial load to the drill rod 5 of the target rock drill 7 under test to simulate The axial resistance during the drilling process, the advancement speed and stroke of the drill rod 5 are all controlled by the rock drill 7. Different parameters are set according to the test requirements. The drill rod 5 pushes the mobile platform 11 to move slowly in the axial direction, and at the same time, the load simulation mechanism 1 is slowly retracted under the thrust of the drill rod 5; after the drill rod 5 is advanced to the set distance, the rock drill 7 stops impacting and advancing, and after reversing, it separates from the transmission box 401 and returns to the initial position; this transmission box 401 is connected to the end of the drill rod 5, so that the rotary load is applied to the end of the drill rod 5, which is closer to the actual working conditions. The vibration absorption mechanism 3 and the thrust load simulation mechanism are separate mechanisms with low structural complexity, which reduces the manufacturing difficulty and cost, and is more convenient to maintain and replace; by setting a mobile component to adjust the position of the transmission box 401 to match the drill rod 5, the docking operation steps are simplified, the docking time and difficulty are shortened, and the test efficiency is effectively improved.

[0042] In one embodiment, the moving assembly includes a base plate 409 provided on the moving platform 11, a transverse guide rail 411 provided on the base plate 409, a bracket 415 slidably connected to the transverse guide rail 411, a longitudinal guide rail 414 provided on the bracket 415 and used for mounting the transmission box 401, and a locking mechanism 412 for fixing the position of the transmission box 401, wherein the transverse guide rail 411 is slidably connected to the transverse slider 406, the bracket 415 is mounted on the transverse slider 406, the longitudinal guide rail 414 is symmetrically distributed and provided on the bracket 415, and the longitudinal guide rail 414 is slidably connected to the longitudinal guide rail 414. The sliders 413 are respectively connected to both sides of the transmission box 401; it should be understood that the layout direction of the transverse guide rail 411 is perpendicular to the axial direction of the device; when adjusting the transverse position of the transmission box 401, the longitudinal guide rail 414 drives the transmission box 401 to slide on the transverse slide rail 9, and when adjusting the longitudinal position of the transmission box 401, the longitudinal slider 413 slides on the longitudinal guide rail 414; the locking mechanism 412 includes locking screws respectively threadedly connected to the transverse slider 406 and the longitudinal slider 413. Tightening the locking screws until they hit the corresponding guide rails can achieve positioning and fixation of the corresponding moving direction of the transmission box 401.

[0043] Furthermore, the mobile assembly also includes an adjustment mechanism, which includes a translation screw 404 and a lifting screw 407 arranged on the mobile platform 11, a first screw sleeve 403 threadedly connected to the translation screw 404 is provided on the longitudinal guide rail 414, and a second screw sleeve threadedly connected to the lifting screw 407 is provided on the transmission box 401; the translation screw 404 and the lifting screw 407 are respectively installed on the mobile platform 11 through the mounting seat 405, and the translation screw 404 and the lifting screw 407 are kept in the same position by the mounting seat 405. 7 is fixed in axial position, and by rotating the translation screw 404, the first screw sleeve 403 moves axially along the translation screw 404, thereby driving the longitudinal guide rail 414 and the transmission box 401 to move horizontally; similarly, the rotating lifting screw 407 drives the transmission box 401 to move up and down; for the convenience of operation, the second screw sleeve is arranged longitudinally and mounted on the transmission box 401 through the Z-shaped mounting plate 408, and the lifting screw 407 is arranged transversely on the mobile platform 11 and is connected to the second screw sleeve through a transmission structure such as a bevel gear or a coupling, which makes operation more convenient.

[0044] In one embodiment, the vibration absorbing mechanism 3 includes a cylinder 301, a hydraulic rod 303 passing through the cylinder 301, a piston 302 disposed at a first end of the hydraulic rod 303 and cooperating with the inner cavity of the cylinder 301, and a punching head 305 disposed at a second end of the hydraulic rod 303. The diameter of the through hole formed in the support plate 6 corresponds to the range of motion of the transmission box 401 and the force-bearing surface of the punching head 305. The cylinder 301 is further provided with a guide sleeve 304 to cooperate with the hydraulic rod 303.

[0045] In one embodiment, the piston 302 separates the inner cavity of the cylinder body 301 into a rod cavity and a rodless cavity. The cylinder body 301 includes an oil passage connecting the rod cavity and the rodless cavity. Before the test, the controller 15 controls the hydraulic pump station 16 to adjust the oil pressure entering the vibration absorption mechanism 3 and the reverse thrust cylinder to a set pressure; the oil enters the rod cavity and the rodless cavity respectively through the oil port 307 of the cylinder body 301. Due to the area difference, the thrust in the rod cavity is greater than that in the rodless cavity, and the hydraulic rod 303 is extended to the maximum stroke to prepare for the impact; a damper 306 is provided in the oil passage. When the impact When the striking head 416 hits the receiving punch 305, the hydraulic rod 303 will retract a certain distance, the high-pressure oil in the rodless chamber will be compressed, the pressure will increase, and part of the oil will flow out through the overflow device bypassing the oil inlet hole. The oil pressure will return to the level before the impact, pushing the hydraulic rod 303 to reset and prepare to withstand the next impact; when the oil in the rodless chamber flows out through the damper 306 during the resetting process of the hydraulic rod 303, the damper 306 limits the outflow speed of the oil, thereby avoiding rapid collision between the piston 302 and the guide sleeve 304, and playing a buffering and protective role for the shock absorber.

[0046] In one embodiment, internal teeth are provided in the middle of the main gear 4012, and external teeth for engaging with the internal teeth are provided on the outer wall of the central shaft 4011, so that the transmission connection is stable and easy to assemble and disassemble.

[0047] In one embodiment, a limit switch 14 electrically connected to the controller 15 is provided on the frame, and is used to cut off or switch the oil supply of the hydraulic pump station 16 to the propulsion load simulation mechanism 1 when the mobile platform 11 moves into position;

[0048] Specifically, a front limit sensing unit and a rear limit sensing unit can be provided respectively. The output end of the reverse thrust cylinder extends to push the transmission box 401 to move toward the rock drill 7 based on the mobile platform 11 until it touches the front limit sensing unit. The controller 15 cuts off the oil source of the reverse thrust cylinder to stop extending it, and then performs subsequent test operation steps.

[0049] During the test, if the driver incorrectly sets the propulsion distance or the system fails, causing the drill rod 5 to push the sliding platform 12 to continuously retreat and trigger the rear limit sensing unit, the proportional relief valve in the hydraulic pump station 16 controls the rod chamber pressure of the reverse thrust cylinder to automatically increase, preventing the output end of the reverse thrust cylinder from continuing to retract, and an alarm device can be set to interact to remind the operator.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
