Description

Technical Field

[0001] This invention relates to the field of material surface treatment technology for submerged arc furnaces, specifically to a calcium carbide material surface treatment machine and its supporting device. Background Technology

[0002] During the smelting process of calcium carbide, a hard shell easily forms inside the furnace. Below the hard shell is molten liquid calcium carbide, and above it are solid granular semi-coke and quicklime. As the weight on top increases, the hard shell will suddenly collapse at a certain point, causing the molten liquid calcium carbide to splash. More seriously, the gas pressure under the hard shell will be suddenly released, generating a shock wave that damages the furnace. To prevent safety issues, the hard shell needs to be broken up with steel rods. The invention of the material surface processing machine for calcium carbide furnaces has saved labor, improved work efficiency, and reduced the labor intensity of manual material surface processing.

[0003] The rock drill on the calcium carbide material processing machine is mounted on a rail via a trolley. It is used to install impact devices such as steel chisels and is driven by a traction device to reciprocate on the rail to adjust the position of the steel chisels. During operation, due to the pitching and swaying of the trolley along with the vibration of the rail and the rock drill, the service life of the trolley rollers will be greatly reduced after a period of use. Furthermore, calcium carbide debris scattered in the calcium carbide furnace enters the bearings of the trolley, further accelerating the deterioration of the rollers. This can also cause the trolley to loosen with the rail, resulting in a significant reduction in the stability between the trolley and the rail. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention provides a calcium carbide material surface processing machine and its supporting device.

[0005] This invention provides the following technical solution: a supporting device for a calcium carbide surface processing machine, comprising a rock drill trolley, wherein the side of the rock drill trolley and the top side of an anti-tilting wheel support frame are fixedly connected, and an anti-tilting wheel mounting seat is provided on the side of the anti-tilting wheel support frame below the rock drill trolley. The anti-tilting wheel mounting seat is in the shape of a boss, the top of which is cylindrical. The bottom surface of the anti-tilting wheel mounting seat is fixedly connected to the anti-tilting wheel support frame. An anti-tilting wheel is provided at the top of the anti-tilting wheel mounting seat. The anti-tilting wheel includes an anti-tilting roller, a cylindrical roller bearing, and a shaft elastic retaining ring. The top of the anti-tilting wheel mounting seat is fixedly sleeved with the inner ring of the cylindrical roller bearing, and the outer ring of the cylindrical roller bearing is fixedly sleeved with the anti-tilting roller. A shaft elastic retaining ring is provided on the side wall of the anti-tilting wheel mounting seat near the rail of the cylindrical roller bearing. The shaft elastic retaining ring is used to fix the cylindrical roller bearing.

[0006] Preferably, the cylindrical roller bearing has a dustproof plate on its outer ring, and an elastic retaining ring for fixing the dustproof plate is provided on the inner wall of the anti-warping roller outside the dustproof plate. The anti-warping roller mounting base and the anti-warping roller support frame have through holes along the rotation axis of the cylinder at the top of the anti-warping roller mounting base. The anti-warping roller mounting base is provided with a straight-through pressure injection cup near the through hole of the anti-warping roller support frame. The oil injection of the cylindrical roller bearing is achieved through the cooperation of the straight-through pressure injection cup and the dustproof plate.

[0007] Preferably, the anti-tilting wheel support frame and the rock drill trolley are fixedly installed by using hexagonal screws and locating pins.

[0008] Preferably, the anti-tilting wheel mounting base includes a sealing plate and a movable shaft. The sealing plate is fixedly connected to the anti-tilting wheel support frame. The movable shaft is movably sleeved with both the sealing plate and the anti-tilting wheel support frame. The fastening surfaces of the sealing plate and the anti-tilting wheel support frame are both annularly slotted along the axial direction of the movable shaft. The two slots are simultaneously fastened to form an annular cavity. An annular plate is provided inside the annular cavity. The annular plate is fixedly engaged with the outer wall of the movable shaft. Several shock-absorbing springs are provided on the side of the annular plate near the anti-tilting wheel support frame.

[0009] Preferably, the anti-tilting wheel support frame includes a support column and a mounting ring. The support column is used to connect the rock drill trolley and the anti-tilting wheel mounting seat. The mounting ring is coaxial with the movable shaft. A plurality of hydraulic rods are provided on one side of the mounting ring. One end of the hydraulic rod is fixedly mounted on the mounting ring, and the other end of the hydraulic rod is movably sleeved with a wedge block. The end of the wedge block near the hydraulic rod is fixedly connected to a return spring, and the other end of the return spring is fixedly connected to the hydraulic rod. The anti-warping roller has several radially formed slots on its side. These slots are arranged in a zero-pitch circular array on the side of the anti-warping roller. The depth of the slots gradually decreases from the edge of the anti-warping roller towards the center. The slots can be fitted and engaged with wedge blocks.

[0010] Preferably, a hydraulic cylinder is embedded in the annular cavity, and the annular plate is located inside the hydraulic cylinder and cooperates with the inner wall of the hydraulic cylinder to form a piston. The hydraulic cylinder is filled with hydraulic oil, and a damping hole for connecting the two inner cavities is opened on the piston. A one-way valve core is provided at one end of the damping hole near the anti-tilting wheel support frame. A telescopic rod is fixedly connected to one side of the one-way valve core, and one end of the telescopic rod is fixedly connected to the inner wall of the hydraulic cylinder. A compression spring is sleeved on the outside of the telescopic rod to press the one-way valve core tightly at the damping hole. An electromagnet is fixedly installed on the inner wall of the hydraulic cylinder. The electromagnet is used to attract the one-way valve core away from the damping hole. When the rock drill trolley moves, the electromagnet is energized and attracts the valve core. When the rock drill trolley is stationary, the electromagnet is disconnected and has no attraction ability.

[0011] Preferably, several magnets are provided on the side of the anti-tilting roller near the sealing plate, and a coil is provided on the side of the sealing plate corresponding to each magnet. The induced current generated by the coil is amplified and then used to control the opening and closing of the electromagnet.

[0012] A calcium carbide surface processing machine includes a support device, a boom mechanism, and a track set on the boom mechanism as described above. A rock drill trolley is provided on the track, and the rock drill is slidably set on the track via the rock drill trolley.

[0013] The present invention has the following beneficial effects: 1. This invention enhances the shear resistance of the trolley by adding a positioning pin to the connecting parts of the mounting bracket and the rock drill trolley. At the same time, it protects the bearing by setting a dustproof plate and makes an opening on the rotating shaft of the anti-tilting wheel to cooperate with the dustproof plate to enable oil injection without disassembly.

[0014] 2. This invention reduces the axial impact on the bearing during trolley movement by incorporating a shock-absorbing device on the anti-tilting wheel mounting component, thereby further protecting the safety of bearing use.

[0015] 3. This invention uses a wedge block between the anti-tilting wheel and the mounting plate. When the trolley is stationary, the wedge block fills the gap between the anti-tilting wheel and the mounting plate without power by swinging left and right. The rigidity of the wedge block itself makes the anti-tilting wheel press against the rail web, reducing the impact on the bearing, assisting in the stability of the trolley, and helping the rack and pinion of the rock drill trolley to share the reaction force of the impact device.

[0016] 4. This invention uses a ring plate as a piston structure and damping holes to achieve shock absorption and energy dissipation, thereby protecting the axial safety performance of the roller bearing. At the same time, the opening and closing of the one-way valve is controlled by an electromagnet, so that when the trolley is stationary, the anti-tilting roller and the rail can be pressed tightly together to maintain stability, and when the trolley is moving, the anti-tilting roller and the rail can be connected with low friction to maintain shock absorption performance.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1

[0021] Please see Figures 1 to 3A supporting device for a calcium carbide surface processing machine includes a rock drill trolley 9. The side of the rock drill trolley 9 is fixedly connected to the upper part of the side of the anti-tilting wheel support frame 3 near the rail. The connecting parts include hexagonal socket screws and positioning pins 30. The positioning pins 30 are added to enhance the shear resistance of the rock drill trolley 9. An anti-tilting wheel mounting seat 2 is provided below the rock drill trolley 9. The anti-tilting wheel mounting seat 2 is in the shape of a boss, and the top of the boss is cylindrical. The bottom surface of the anti-tilting wheel mounting seat 2 is fixedly connected to the side of the anti-tilting wheel support frame 3 near the rail. The anti-tilting wheel mounting seat 2 and the anti-tilting wheel support frame 3 have through holes along the axial direction of the anti-tilting wheel mounting seat 2. A straight-through pressure injection cup 7 is provided at the opening of the anti-tilting wheel mounting seat 2 near the anti-tilting wheel support frame 3. The cylindrical outer wall of the bearing is fixedly sleeved with the inner ring of the cylindrical roller bearing 5. The outer ring of the cylindrical roller bearing 5 is fixedly sleeved with an anti-warping roller 1. A shaft elastic retaining ring 8 is provided between the inner ring of the cylindrical roller bearing 5 and the outer wall of the anti-warping roller mounting seat 2. The shaft elastic retaining ring 8 is used to fix the cylindrical roller bearing 5. The outer ring of the cylindrical roller bearing 5 is covered with a dustproof plate 6. A hole elastic retaining ring 4 is provided between the outer edge of the dustproof plate 6 and the inner wall of the anti-warping roller 1. The hole elastic retaining ring 4 is used to press the dustproof plate 6 against the outer ring of the cylindrical roller bearing 5. Lubricating grease is injected into the through hole in the anti-warping roller mounting seat 2 through a straight-through pressure grease cup 7. The lubricating grease is dispersed into the interior of the cylindrical roller bearing 5 by the obstruction of the inner wall of the dustproof plate 6, achieving the effect of convenient lubrication.

[0022] The right side of the anti-tilting roller 1 and the boss of the anti-tilting roller mounting seat 2 fit tightly together, locking the grease that overflows from the rollers of the cylindrical roller bearing 5, preventing the grease from leaking to the outside of the anti-tilting roller 1, ensuring that the cylindrical roller bearing 5 can maintain lubrication for a long time, and extending the service life of the cylindrical roller bearing 5.

[0023] By modifying the structure of the anti-tilting wheel mounting base 2, it is now fixed using hexagonal socket head cap screws and locating pins. The mechanical strength and anti-loosening performance of the anti-tilting wheel mounting base 2 are far superior to the mounting method using bearing mounting shafts and round nuts, preventing the cylindrical roller bearing 5's mounting shaft from loosening and breaking. This also solves the problem of insufficient mechanical strength and easy loosening of the anti-tilting wheel mounting shaft on the rock drill trolley 9. By adding anti-tilting rollers 1 to tightly wrap the outer ring of the cylindrical roller bearing 5, the bearing's compressive and impact resistance is improved. The addition of a dustproof plate 6 prevents the cylindrical roller bearing 5 from directly contacting calcium lime during field use, solving the problem of calcium lime easily entering the bearing and shortening its service life.

[0024] Example 2

[0025] Please see Figure 4 Figure 5This embodiment is a further improvement on the anti-tilting wheel mounting base 2 of Embodiment 1. The anti-tilting wheel mounting base 2 includes a sealing plate 20 and a movable shaft 21. The sealing plate 20 is fixedly connected to the anti-tilting wheel support frame 3, and the fixing method can be welding, anchor bolt fixing, etc. One end of the movable shaft 21 is movably sleeved with the sealing plate 20, and the other end of the movable shaft 21 is fixedly sleeved with the inner ring of the cylindrical roller bearing 5. A through hole is opened in the movable shaft 21 and a straight-through pressure injection cup 7 is provided. Annular grooves are made on the contact surfaces of the sealing plate 20 and the anti-tilting wheel support frame 3. When the sealing plate 20 and the anti-tilting wheel support frame 3 are in contact, the sealing plate 20 and the anti-tilting wheel support frame 3 are connected. After the support frame 3 is fastened, the slotted synchronous fastening forms an annular cavity. An annular plate 22 is placed inside this annular cavity. The annular plate 22 is fixedly engaged with the movable shaft 21. The annular plate 22 is used to limit the range of axial movement of the movable shaft 21. Several shock-absorbing springs 23 are provided on the side of the annular plate 22 near the anti-tilting wheel support frame 3. When the trolley swings left and right, the anti-tilting wheel and the movable shaft 21 dissipate the axial impact on the cylindrical roller bearing 5 through the compression and rebound of the shock-absorbing springs 23.

[0026] Example 3

[0027] Please see Figures 6 to 9 This embodiment is a further improvement on the shock absorption device in Embodiment 2. The anti-tilting wheel support frame 3 includes a support column 31 and a mounting ring 32. The support column 31 is used to connect the rock drill trolley 9 and the anti-tilting wheel mounting seat 2. The mounting ring 32 is fixedly connected to the support column 31 or integrally formed. The mounting ring 32 is coaxial with the movable shaft 21. Several hydraulic rods 33 are provided on the side of the mounting ring 32 and radially. The hydraulic rods 33 are connected to the hydraulic system on the rock drill trolley 9. One end of the hydraulic rod 33 is fixedly connected to the mounting ring 32. The other end is movably connected to the wedge block 35. The end of the wedge block 35 near the hydraulic rod 33 is fixedly connected to the return spring 34. One end of the return spring 34 is fixedly connected to the end of the hydraulic rod 33 away from the wedge block 35. One side of the wedge block 35, the output end of the hydraulic rod 33 and the return spring 34 are all embedded in the sealing plate 20. A groove 12 is radially provided on the side of the anti-tilting roller 1. The depth of the groove 12 gradually becomes shallower from the edge of the anti-tilting roller 1 towards the axis. The wedge block 35 can be inserted into the groove 12 and slide along the length direction.

[0028] When the trolley is stationary, the power of the hydraulic system is cut off. The return spring 34 rebounds and drives the wedge block 35 to move toward the movable shaft 21. Under the torque of the return spring 34, the wedge block 35 tends to be perpendicular to the sealing plate 20. The torque here can be understood as the initial installation position of the return spring 34 and the wedge block 35 being the side of the wedge block 35 perpendicular to the sealing plate 20. Under the action of external force, the wedge block 35 rotates itself and drives the return spring 34 to be torsion in the circumference. Under the action of no external force, the return spring 34 can drive the wedge block 35 to return to its original initial state. As the wedge block 35 moves toward the movable shaft 21, it gradually comes into contact with the two surfaces of the slot 12 and the sealing plate 20. When the rock drill trolley 9 swings, the gap between the sealing plate 20 and the slot 12 widens. The wedge block 35 continues to move toward the movable shaft 21 and fills the increased gap caused by the swinging motion, ultimately causing the anti-tilting roller 1 to press tightly against the web of the rail. At this point, the trolley becomes stable due to the contact between the anti-tilting roller 1 and the rail, protecting the bearings. When the impact structure on the rock drill trolley 9 operates, the friction between the side of the anti-tilting roller 1 and the rail can offset some of the reaction force from the impact structure, preventing all the impact from acting on the rack line that pulls the rock drill trolley 9, thus extending the service life of the rack line. For ease of understanding, the rack line here refers to the traction system of the rock drill trolley 9 (not shown in the figure), which pulls the rock drill trolley 9 forward or backward along the length of the rail via a chain.

[0029] When the rock drill trolley 9 moves, the anti-tilting roller 1 starts to rotate, and the edge of the slot 12 pushes the wedge block 35 to rotate to the side of the hydraulic rod 33. The hydraulic rod 33 is connected to the hydraulic system on the rock drill trolley 9, lifting the wedge block 35 to the mounting ring 32. The wedge block 35 and the slot 12 are released from their limit, so that the distance between the anti-tilting roller 1 and the sealing plate 20 returns to a variable state, thereby restoring the rock drill trolley 9 to a low friction resistance and shock absorption state when it moves.

[0030] To ensure that the wedge block 35 can accurately engage with the slot 12 without misalignment, the width of the slot 12 is adapted to the width of the wedge block 35, and several slots 12 are arranged in a zero-pitch circular array on the side of the anti-warping roller 1.

[0031] Therefore, when the rock drill trolley 9 is stationary, its left-right swaying causes the gap between the anti-tilting roller 1 and the sealing plate 20 to fluctuate. This variation allows the wedge block 35 to slide along the groove 12 under the elastic force of the return spring 34. The change in the depth of the groove 12 allows the wedge block 35 to fill the movable gap between the anti-tilting roller 1 and the sealing plate 20, thus ensuring the anti-tilting roller 1 presses firmly against the rail web and guarantees the stable operation of the rock drill trolley 9. When the rock drill trolley 9 begins to move, the hydraulic rod 33 can drive the wedge block 35 to disengage, restoring the rock drill trolley 9's walking friction resistance and shock absorption performance.

[0032] Example 4

[0033] Please see Figure 10 This embodiment is a further improvement on embodiment two. Sealing rings 27 are provided on the surfaces of the sealing plate 20 and the anti-tilting wheel support frame 3 that contact the movable shaft 21. A hydraulic cylinder 26 is installed within the annular cavity formed by the fastening of the sealing plate 20 and the anti-tilting wheel support frame 3. In this embodiment, the annular plate 22 in embodiment two is a piston. The hydraulic cylinder 26 and the piston together constitute a piston-cylinder configuration. The piston is fixedly engaged with the movable shaft 21. Hydraulic oil is filled into the hydraulic cylinder 26. A damping hole 28 is provided on the piston to allow the hydraulic oil on both sides of the piston to communicate. A one-way valve core 39 is provided at the end of the damping hole 28 near the anti-tilting wheel support frame 3. The narrow end of the one-way valve core 39 is used to block the damping hole 28. The thick end of the one-way valve core 39 is fixedly connected to one end of the telescopic rod 38, and the other end of the telescopic rod 38 is fixedly connected to the inner wall of the hydraulic cylinder 26. A compression spring 37 is provided on the outer side of the telescopic rod 38. The two ends of the compression spring 37 are fixedly connected to the one-way valve core 39 and the hydraulic cylinder 26, respectively. The compression spring 37 is used to press the one-way valve core 39 tightly at the damping hole 28. An electromagnet 36 is fixedly installed on the inner wall of the hydraulic cylinder 26 on the side of the one-way valve core 39 away from the anti-tilting roller 1. The electromagnet 36 is powered by the circuit system on the rock drill trolley 9 and is used to attract the one-way valve core 39. When the rock drill trolley 9 moves, the electromagnet 36 is energized and attracts the one-way valve core 39. When the rock drill trolley 9 is stationary, the electromagnet 36 is disconnected and has no attraction capacity.

[0034] To further enable the rock drill trolley 9 to accurately control the opening and closing of the electromagnet 36 during automatic movement, several magnets 13 are provided on the side of the anti-tilting roller 1 near the sealing plate 20. Each magnet 13 is provided with a coil 24 on the side of the sealing plate 20. The coil 24 is connected to the circuit on the rock drill trolley 9. The induced current generated by the coil 24 is amplified and then used to control the opening and closing of the electromagnet 36.

[0035] When the rock drill trolley 9 moves, the anti-tilting roller 1 drives the magnet 13 to rotate synchronously, generating an induced current in the coil 24. This induced current is amplified by an external circuit, triggering the circuit on the rock drill trolley 9 to supply power to the electromagnet 36. The electromagnet 36 attracts the one-way valve core 39, at which point the damping orifice 28 opens. Under the action of the piston and hydraulic oil, it provides axial damping and protects the cylindrical roller bearing 5. When the rock drill trolley 9 is stationary, the electromagnet 36 loses power, and the one-way valve core 39 is blocked by the elastic force of the compression spring 37. Nikon 28, the hydraulic oil can only flow unidirectionally from the side near the anti-tilting roller 1 to the side near the anti-tilting roller support frame 3. When the rock drill trolley 9 is swayed by external force, the hydraulic oil on the side of the piston near the anti-tilting roller support frame 3 increases continuously, causing the piston to drive the movable shaft 21 and the anti-tilting roller 1 to move towards the rail web until the anti-tilting roller 1 and the rail are pressed together. At this point, the rock drill trolley 9 is stable. When the rock drill trolley 9 is started, the electromagnet 36 is connected and then attracts the one-way valve core 39, and the rock drill trolley 9 restores the shock absorption effect.

[0036] Example 5

[0037] Please see Figure 11 A calcium carbide surface processing machine includes a bearing device, a boom mechanism, and a track 11 provided on the boom mechanism as described in the above embodiments. A rock drill trolley 9 is provided on the track 11. An impact device 91 is provided on the top of the rock drill trolley 9. Both ends of the rock drill trolley 9 are connected to a traction device 92. The rollers on the rock drill trolley 9 are located between the upper and lower flanges of the track 11. Due to the locking of the upper and lower flanges of the track 11, the rock drill trolley 9 will not derail due to tilting when the track 11 changes pitch. By locking the track 11, the rock drill trolley 9 helps the traction device 92 to bear the reaction force generated by the impact device 91 when it works. On the other hand, by locking the track 11, the rock drill trolley 9 is rigidly connected to the track 11, avoiding damage to the bearings at the rollers of the rock drill trolley 9 caused by the left and right swing of the track 11. Furthermore, the boom mechanism can be positioned above the traveling mechanism (not shown in the figure), and the boom mechanism can perform pitching and swinging movements relative to the traveling mechanism. The traveling mechanism is also used to drive the boom mechanism to move, but the embodiments of this application are not limited thereto.
