Description

Technical Field

[0001] The invention relates to the field of drill rod quenching, and in particular to a drill rod quenching device for a mining skidding trolley breaker hammer. Background Art

[0002] In mining, drill rods used in mining trolley breaker hammers are key components, undertaking arduous tasks such as rock crushing. Quenching drill rods is a crucial process for improving their hardness, wear resistance, and fatigue strength. The basic process for conventional quenching is as follows: Newly produced drill rods are first heated to above the critical temperature, held for a sufficient time to fully austenitize the structure, and then rapidly cooled. Through phase transformation, a strengthening structure, such as martensite, is obtained, thereby enhancing the overall mechanical properties of the drill rod. However, in actual use, due to long-term exposure to high-frequency impact, alternating stress, and harsh working environments, the surface and interior of drill rods are prone to cracks, wear, and reduced hardness. These damages can reduce the working performance of drill rods. To extend the service life of drill rods and reduce production costs, it is necessary to quench and repair damaged old drill rods.

[0003] Currently, most quenching devices on the market are designed only for newly produced drill rods, and rarely can they quench and repair old drill rods after use. After disassembly, old drill rods often rely on manual repair, which is not only inefficient but also difficult to guarantee repair quality. In addition, before repairing old drill rods, it is necessary to accurately determine whether they are still worth repairing to avoid ineffective repair work on drill rods that are meaningless and result in wasted resources. During the repair process, since damage is often concentrated in a localized area, it is necessary to quickly locate the repair location and perform precise heating and quenching on the local area of ​​the drill rod to improve repair efficiency and quality.

[0004] In the prior art, patent publication CN111041545B discloses a drill rod fatigue crack repair device. This device utilizes an electrolytic cell, a drill rod rotation adjustment assembly, a sliding heating assembly, and a drive assembly on a workbench to work together. The drill rod rotation adjustment assembly drives the drill rod through various stations, including mounting, electrolytic cleaning, drying, preheating, and pulse current repair, allowing multiple drill rods to be processed simultaneously at different stations. The sliding heating assembly preheats the drill rod surface and, combined with the pulse current, promotes crack healing. However, while this technology has improved some of the original problems, there are still areas that require further optimization to better meet actual repair needs.

[0005] Before repair, old drill rods are often clinging to residues like slag and oil. However, the aforementioned device relies solely on the electrolytic cell to electrolytically remove the oxide film on the microcracks of the drill rod, failing to fully clean the residue on the rod's exterior. This causes dirt to fall into the cell during electrolysis, contaminating the electrolyte, impacting its effectiveness and lifespan, and potentially clogging the cell's circulation system, increasing equipment maintenance costs and frequency.

[0006] While the aforementioned device can repair multiple drill rods simultaneously, high heat remains on the outside of the rods after repair. Because the rods can only be removed manually, operators must wait for them to cool naturally before safely removing them. This significantly reduces repair efficiency and prolongs the overall repair cycle, failing to meet the urgent need for rapid repair and commissioning of drill rods at mines and other work sites.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing drill rod repairing device. Summary of the Invention

[0041] In addition, rotating screws 15 are rotatably penetrated by the inner walls on both sides of the rectangular frame 10, and the rotating screws 15 are threadedly connected to the cross plate 12. One side of the rotating screw 15 extends to the outside of the rectangular frame 10 and can be connected to an external drive motor to drive the rotating screw 15 to rotate to drive the cross plate 12 to move in the rectangular frame 10. Furthermore, an installation cavity is also provided in the cross plate 12, and one side of the installation cavity is connected to the sliding groove 13. The operator can install a moving rack in the sliding groove 13 on the outside of the sliding plate 14, and install a driving motor in the installation cavity, and set a driving gear meshing with the moving rack on the main shaft of the driving motor. Starting the driving motor can drive the sliding plate 14 to move left and right in the sliding groove 13 through the cooperation of the driving gear and the moving rack.

[0042] A heating frame 16 is also provided on one side of the rectangular frame 10. Several heating cavities are provided on the outer wall of the heating frame 16 and the rectangular frame 10. A heating detection unit 6 for heating and detecting the drill rod is provided in the heating cavity. The drill rod can be driven by the supporting unit 2 from the port of the heating cavity into the heating detection unit 6, and then the drill rod is subjected to quality inspection and quenching repair by the heating detection unit 6.

[0043] Reference Figure 3 and Figure 4The supporting unit 2 is used for supporting the drill rod, and specifically comprises a supporting plate 20, a plurality of rectangular grooves 21, a plurality of swing grooves 22, a plurality of swing shafts 23, a plurality of swing plates 24, a lower circular plate 25 and an upper circular plate 26. The supporting plate 20 is arranged at the upper end of the sliding plate 14, that is, the sliding plate 14 can drive the supporting plate 20 to move synchronously. The supporting plate 20 is provided with the plurality of rectangular grooves 21, and the inner wall of one side of each rectangular groove 21 is provided with the swing groove 22. The swing shaft 23 penetrates through the supporting plate 20 and extends into the swing groove 22. The swing shaft 23 is provided with the spring clamping piece, and the swing plate 24 is arranged outside the swing groove 22. The swing plate 24 is provided with the lower circular plate 25. The supporting plate 20 is further provided with the upper circular plate 26 corresponding to each rectangular groove 21.

[0044] The swing shaft 23 can drive the lower circular plate 25 to swing in the rectangular groove 21 and the swing groove 22 through the swing plate 24. In use, the lower circular plate 25 is driven by the swing shaft 23 to swing into the swing groove 22 for storage. Then the drill rod is moved from the lower end to the upper end of the rectangular groove 21 to contact the inner diameter of the upper circular plate 26. Then the lower circular plate 25 is driven by the corresponding swing shaft 23 to contact the outer side of the drill rod. At this time, the upper circular plate 26 and the lower circular plate 25 cooperate to support and limit the drill rod. The swing shaft 23 is limited by the corresponding spring clamping piece in the initial state.

[0045] The spring clamping piece comprises a spring push rod mounted in the supporting plate 20, and a plurality of triangular clamping grooves are arranged outside the swing shaft 23. The extension end of the spring push rod is provided with a clamping block clamped in the corresponding clamping groove. Therefore, when the swing shaft 23 swings, the extension end of the spring push rod can be indirectly contacted to drive the clamping block to no longer contact the clamping groove. At this time, the swing shaft 23 can be driven to rotate by the external driving motor. After the lower circular plate 25 contacts the outer side of the drill rod, the clamping block of the spring push rod can continue to limit the swing shaft 23, so that the swing shaft 23 has enough supporting force to support the bottom of the drill rod. Further, a plurality of spring clamping pieces can be arranged between the single swing shaft 23 and the supporting plate 20 to clamp and limit the clamping shaft, so as to ensure that the clamping shaft has enough supporting force.

[0046] Referring to Figure 5As shown, the rectangular plate 1 is also provided with a supporting assembly 3 that cooperates with the supporting unit 2 to support the drill rod; specifically, the supporting assembly 3 includes a limit plate 30, a supporting block 31, a semicircular groove 32, a structural groove 33, a strip plate 34, a U-shaped plate 35, a sliding frame 36 and a sliding shaft 37. The two limit plates 30 are symmetrically arranged at the upper end of the rectangular plate 1 and are located on both sides of the rectangular frame 10. A supporting block 31 is sliding on the limit plate 30. The supporting block 31 is provided with several semicircular grooves 32 that correspond one to one with the rectangular grooves 21, that is, the supporting block 31 can move up and down on the limit plate 30, and the drill rod can be placed in several semicircular grooves 32 on one side, so that the supporting block 31 can drive the drill rod to move up and down.

[0047] A structural groove 33 is provided on one side of the rectangular plate 1, and a strip plate 34 is provided at the bottom of the rectangular frame 10. A C-shaped plate 35 is rotated at the end of the strip plate 34, and the extension sections on both sides of the C-shaped plate 35 slide through the structural groove 33 on the corresponding side to provide a sliding frame 36 corresponding to the supporting block 31, and a sliding shaft 37 extending into the sliding frame 36 is provided on one side of the supporting block 31.

[0048] That is, in actual use, the external drive motor is connected to the U-shaped plate 35 to drive the U-shaped plate 35 to swing on the strip plate 34. The structural groove 33 is used to avoid the bending sections on both sides of the U-shaped plate 35. When the U-shaped plate 35 swings, it can drive the sliding frame 36 to move synchronously. The sliding frame 36 can drive the supporting block 31 to move up and down under the limit of the limit plate 30 through the sliding shaft 37. When a drill rod is placed in the semicircular groove 32 on one side, the drill rod is placed in the semicircular groove 32 on the other side. The corresponding supporting block 31 drives several drill rods to descend, and the swing shaft 23 drives the lower circular plate 25 to retract into the swing groove 22. Then the supporting block 31 drives the drill rod to rise, so that the end of the drill rod is located in the rectangular groove 21 and finally contacts the upper circular plate 26. Then the swing shaft 23 drives the lower circular plate 25 to support the outside of the drill rod, and then the supporting block 31 descends. At this time, the drill rod is clamped by the upper circular plate 26 and the lower circular plate 25 and is driven into the rectangular frame 10 for repair (quenching) work.

[0049] When the repair is completed, the supporting unit 2 drives the drill rod from the through groove 11 on the other side to the corresponding supporting block 31 on the other side. At this time, the supporting block 31 on the other side rises so that the drill rod can enter the corresponding semicircular groove 32. At this time, the swing shaft 23 drives the lower circular plate 25 to no longer support the lower end of the drill rod. At this time, the drill rod is completely supported by the corresponding supporting block 31, and then the supporting block 31 drives the drill rod to descend, and the supporting unit 2 is driven back to the initial position by the cross plate 12 and the sliding plate 14. Repeating the above steps can achieve continuous repair of the drill rod.

[0050] Reference Figure 6As shown, a cleaning unit 4 for cleaning the drill rod is also provided in the rectangular frame 10; specifically, the cleaning unit 4 includes a partition plate 40, a storage chamber 41, a push plate 42, a push cylinder 43, a one-way valve 44, a water outlet 45, a connecting plate 46 and a downward pressure cylinder 47. The partition plate 40 is provided on the inner wall of the rectangular frame 10, and the area between the partition plate 40 and the rectangular frame 10 forms a storage chamber 41. A push plate 42 slides in the storage chamber 41, and a push cylinder 43 is provided on the push plate 42. One side of the push cylinder 43 slides through to the outside of the rectangular frame 10. A one-way valve 44 that penetrates the storage chamber 41 is provided in the push cylinder 43, and the valve of the one-way valve 44 opens toward the storage chamber 41.

[0051] The partition plate 40 is provided with several water outlet ends 45 which are in communication with the storage chamber 41. The water outlet end 45 is a pressure-triggered one-way valve of existing equipment. It is a control valve that automatically opens only when the fluid pressure reaches a set threshold, allowing the fluid to flow out in one direction, and closes to prevent backflow when the pressure is insufficient. That is, the water outlet end 45 can only discharge water after being pressed by sufficient water pressure.

[0052] A connecting plate 46 is installed on the outside of the pushing cylinder 43 , and a pressing cylinder 47 is installed between the connecting plate 46 and the rectangular frame 10 .

[0053] That is, when the drill rod is driven by the supporting unit 2 to move into the rectangular frame 10, the connecting plate 46 is driven down by the downward pressure cylinder 47, and the connecting plate 46 drives the push plate 42 to move in the storage chamber 41 through the push cylinder 43, pushing the water in the storage chamber 41 out from the water outlet 45, and the pushed water falls on the outside of the drill rod in the rectangular frame 10, washing away the pollutants on the outside of the drill rod, and can be connected to the upper end port of the push cylinder 43 through an external water supply device, and then water is supplied to the push cylinder 43, and the water enters the storage chamber 41 through the one-way valve 44.

[0054] Continue to refer to Figure 6 、 Figure 7 and Figure 8 As shown, a wiping assembly 5 for wiping the outside of the drill rod is provided on the inner wall of one side of the heating chamber; specifically, the wiping assembly 5 includes a rotating ring 50, a sliding groove 51, an arc plate 52, a scraping plate 53, an electric push rod 54, a dropping groove 55, a receiving frame 56 and a rectangular cavity 57. The rotating ring 50 is rotatably arranged on the inner wall of the heating chamber. Several sliding grooves 51 are opened on the rotating ring 50. An arc plate 52 slides in the sliding groove 51. A scraping plate 53 is provided on the inner side of the arc plate 52, and an electric push rod 54 is installed between the arc plate 52 and the sliding groove 51. The rotating ring 50 can rotate in the heating chamber when driven by an external force, and the electric push rod 54 can drive the corresponding arc plate 52 to move in the sliding groove 51 toward the axis of the rotating ring 50 or away from it. When the arc plate 52 moves, it will drive the scraping plate 53 to move synchronously.

[0055] That is, when the drill rod in the rectangular frame 10 is cleaned by the cleaning unit 4, at this time, the end of the drill rod is moved towards the direction of the rotating ring 50 by the indirect driving of the horizontal plate 12, until the end of the drill rod is inserted into the rotating ring 50, then the rotating ring 50 indirectly drives the arc-shaped plate 52 to rotate, and the electric push rod 54 indirectly drives the scraping plate 53 to contact the outer side of the drill rod, so that the stubborn stains on the outer side of the drill rod are wiped off, and then the end of the drill rod completely enters the heating cavity, and the drill rod is heated by the heating detection unit 6, and during the heating process, the electric push rod 54 can drive the arc-shaped plate 52 and the scraping plate 53 not to contact the outer side of the drill rod, so as to avoid the heat in the drill rod from being transferred to the scraping plate 53 to cause overheating and melting of the scraping plate 53, and then when the next drill rod corresponds to the scraping plate 53, the electric push rod 54 again pushes the arc-shaped plate 52 to drive the scraping plate 53 to contact the outer side of the drill rod.

[0056] The bottom wall in the rectangular frame 10 and the rectangular plate 1 are provided with a falling groove 55, and the bottom of the rectangular frame 10 is also provided with a receiving frame 56 corresponding to the falling groove 55. If the drill rod is damaged during the heating process, or it is detected that there is no possibility of repair, at this time, when the drill rod is driven out by the corresponding supporting unit 2, the corresponding swing shaft 23 can be driven by an external force to cancel the support of the bottom of the drill rod, so that the drill rod falls off from the rectangular groove 21, and then falls from the falling groove 55 to the receiving frame 56, while the remaining drill rods that have been repaired are supported by the corresponding supporting blocks 31, and the water outlet 45 can also flow out from the gap between the falling groove 55 and the receiving frame 56. The operator can place a receiving frame (not shown) on the ground to receive the water, and the water flow can fall into the receiving frame for subsequent use.

[0057] The rectangular frame 10 is also provided with a rectangular cavity 57 that communicates with the plurality of heating cavities, and the plurality of rotating rings 50 are connected by belt transmission.

[0058] In the specific implementation process, an external motor can be installed in the rectangular cavity 57, and the main shaft of the external motor is connected to one side of the rotating ring 50 by belt transmission, so that the external motor can drive one side of the rotating ring 50 to rotate by belt transmission, and one side of the rotating ring 50 can drive the other rotating rings 50 to rotate synchronously by belt transmission.

[0059] Referring to Figure 8 and Figure 9As shown, the heating detection unit 6 is used to heat and detect the drill rod; specifically, the heating detection unit 6 includes an annular plate 60, a heating magnetic ring 61, a ratchet member 62, an accommodating chamber 63, a reset push spring 64 and a contact plate 65, the annular plate 60 is rotatably arranged inside the heating chamber, a plurality of heating magnetic rings 61 are arranged on the inner diameter of the annular plate 60, and a ratchet member 62 is arranged between the annular plate 60 and the rotating ring 50, that is, the rotating ring 50 can drive the annular plate 60 to rotate in the heating chamber through the ratchet member 62, and the annular plate 60 can drive the heating magnetic ring 61 to heat the drill rod inserted into the heating chamber when rotating, and the rotation of the heating magnetic ring 61 can uniformly heat the drill rod, so that the heating magnetic ring 61 can quickly heat the drill rod to a predetermined quenching temperature.

[0060] Furthermore, when the wiping assembly starts to wipe the drill rod, since the drill rod is being wiped and wiping and heating cannot be performed at the same time, the rotating ring in the wiping assembly rotates in the opposite direction. Due to the one-way transmission characteristics of the ratchet part, the rotating ring does not drive the annular plate to rotate through the ratchet part at this time, thereby preventing the larger annular plate from idling and causing energy waste. Then, when heating is performed, the rotating ring rotates in the forward direction and drives the annular plate to rotate through the ratchet part, thereby achieving uniform heating of the drill rod.

[0061] The heating frame 16 is also provided with several accommodating cavities 63 corresponding to the heating cavities one by one. A reset spring 64 is installed in the accommodating cavity 63. The end of the reset spring 64 is installed with a contact plate 65 located in the heating cavity. An ultrasonic detection device (known technology) is installed in the contact plate 65.

[0062] When the drill rod is inserted into the heating chamber, its end pushes the contact plate 65 to compress the reset spring 64, and the reset spring 64 provides support for the drill rod through the contact plate 65; at this time, the ultrasonic detection equipment in the contact plate 65 is synchronously started, and internal defects are detected in real time during the heating process of the drill rod, ensuring accurate identification of defective products before quenching. After heating is completed, the drill rod is transferred from the supporting unit 2 to the rectangular frame 10, and then water is discharged through the water outlet 45 to rinse the heated drill rod to complete quenching, and the defective drill rods detected are automatically removed through the drop groove 55.

[0063] In practice, a fan-shaped nozzle (commonly known as a fan-shaped nozzle) can be installed at the outlet 45. This nozzle sprays a fan-shaped water mist, which forms a diffuse cooling area within the rectangular frame 10, covering the entire surface of the drill rod. When high-pressure water flows through the fan-shaped nozzle and is atomized, fine water mist particles evenly adhere to the outside of the drill rod. Through the dual mechanisms of vaporization heat absorption and heat conduction, they quickly remove heat from the high-temperature drill rod. At the same time, as the unvaporized water mist slides down the surface of the drill rod, it further cools the lower end area, ensuring that the entire length of the drill rod is in full contact with the water mist, thereby efficiently completing the quenching process.

[0064] Example 2: Reference Figure 10 As shown, on the basis of Example 1, in order to separate the drill rods that fail quenching after the drill rods are tested and heated, a swing assembly 7 for driving the swing shaft 23 to swing is provided on one side of the support plate 20; specifically, the swing assembly 7 includes a linkage gear 70, a driven gear 71, a push rod 72, a push cylinder 73 and a push rack 74. The linkage gear 70 is sleeved on the outer wall of one end of the swing shaft 23 that passes through the support plate 20, and several linkage gears 70 correspond to each other. Furthermore, a driven gear 71 is also sleeved on the outside of the swing shaft 23, and the driven gears 71 on the outsides of several swing shafts 23 are staggered and do not correspond to each other, that is, the linkage gear 70 or the driven gear 71 can drive the swing shaft 23 to rotate when driven by an external force, so as to drive the swing shaft 23 to drive the corresponding lower circular plate 25 to support or not support the bottom of the drill rod.

[0065] A push rod 72 is further provided on the outside of the support plate 20 . A push cylinder 73 is provided at the telescopic end of the push rod 72 through a cylinder seat. A push rack 74 is provided on the telescopic shaft of the push cylinder 73 .

[0066] The push rack 74 is engaged with the plurality of linkage gears 70 , that is, the push rod 72 can drive the push cylinder 73 to move in the front-rear direction, so that the push rack 74 is engaged with the plurality of linkage gears 70 or engaged with the plurality of driven gears 71 respectively.

[0067] When the pushing cylinder 73 drives the pushing rack 74 to engage with several linkage gears 70, the pushing cylinder 73 can drive the linkage gear 70 to rotate together by pushing the rack 74, so that the linkage gear 70 can drive the corresponding swing shaft 23 to rotate together, so that the swing shaft 23 drives the corresponding lower circular plate 25 to rotate in the swing groove 22 and the rectangular groove 21, so that the lower circular plate 25 can uniformly support or not support the drill rod when the drill rod enters or moves away from the rectangular groove 21.

[0068] When the drill rod is quenched, and the unqualified drill rod needs to be separated, it is only necessary to drive the swing shaft 23 corresponding to the unqualified drill rod to swing. At this time, the push rod 72 can drive the push rack 74 to engage with the corresponding driven gear 71 by pushing the cylinder 73. Then, the pushing cylinder 73 can indirectly drive the corresponding swing shaft 23 to swing by pushing the rack 74, so that the swing shaft 23 drives the lower circular plate 25 to no longer support the bottom of the drill rod, so that the drill rod falls off from the rectangular groove 21, and then falls from the drop groove 55 into the receiving frame 56.

[0069] During operation: Step 1: Place the drill rod in the semicircular groove 32 of the supporting block 31 of the supporting assembly 3 on one side of the rectangular plate 1. The external drive motor drives the curved plate 35 to swing on the strip plate 34, driving the sliding frame 36 and the sliding shaft 37 to rise the supporting block 31 and send the drill rod into the rectangular groove 21 of the supporting unit 2 until it contacts the upper circular plate 26.

[0070] Step 2: The swing shaft 23 of the supporting unit 2 overcomes the resistance of the spring clamping part and rotates under the drive of the external drive motor. The swing plate 24 drives the lower circular plate 25 to rotate out of the swing groove 22 and cooperates with the upper circular plate 26 to clamp the drill rod. The spring clamping part is re-limited to provide supporting force.

[0071] Step 3: The rotating screws 15 on both sides of the rectangular frame 10 rotate under the drive of the external drive motor, driving the cross plate 12 to move back and forth in the through slot 11. At the same time, the drive motor in the cross plate 12 drives the sliding plate 14 to move left and right in the sliding slot 13 through the driving gear and the moving rack, so that the supporting unit 2 drives the drill rod through the through slot 11 into the rectangular frame 10.

[0072] Step 4: After the drill rod enters the rectangular frame 10, the downward pressure cylinder 47 drives the connecting plate 46 to descend, and drives the push plate 42 to move in the storage chamber 41 through the push tube 43, pushing the water in the storage chamber 41 out from the water outlet end 45 of the pressure-triggered one-way valve 44 to flush the contaminants on the surface of the drill rod.

[0073] Step 5: After cleaning, the end of the drill rod is driven by the horizontal plate 12 to insert into the rotating circle 50 on one side of the heating chamber. The electric push rod 54 drives the arc plate 52 to drive the scraper plate 53 to fit the drill rod. When the rotating circle 50 rotates, the scraper plate 53 removes stubborn stains. Then the electric push rod 54 retracts the scraper plate 53, and the drill rod enters the heating chamber.

[0074] Step 6: Insert the drill rod into the heating chamber, and the end pushes the contact plate 65 to compress the reset spring 64 to obtain flexible support. The ultrasonic detection equipment in the contact plate 65 is started. When the heating magnetic ring 61 uniformly heats the drill rod, internal defects are detected in real time.

[0075] Step 7: After the heating is completed, the outside of the drill rod is rinsed through the water outlet 45. After quenching is completed, the qualified drill rod is driven by the supporting unit 2 to move out from the through groove 11 on the other side, corresponding to the supporting block 31 on the other side. The supporting block 31 rises to receive the drill rod, and the swing shaft 23 drives the lower circular plate 25 to retract, and the supporting block 31 drives the drill rod to descend to complete the unloading; for the defective drill rod detected, the push rod 72 drives the push rack 74 to engage with the corresponding driven gear 71 through the pushing cylinder 73, drives the swing shaft 23 to swing, and the lower circular plate 25 no longer supports it. The defective drill rod falls off from the rectangular groove 21 and falls into the receiving frame 56 through the drop groove 55.
