Description

Technical Field

[0001] The present application relates to the field of track repair technology, and in particular to an armored vehicle track wear repair device based on laser cladding. Background Art

[0002] During the use of armored vehicle tracks, due to complex terrain, extreme environment and long-term high-load operation, the track chain plates are subjected to periodic impact loads and shear stresses, which often cause severe wear on the track chain plate surface.

[0003] In the related art, the repair of crawler chain plates usually involves disassembling the entire crawler track, then disassembling multiple chain plates in sequence, then repairing the individual chain plates, and finally reinstalling the repaired chain plates. However, the repair of crawler chain plates under this disassembly-repair-reinstallation process often relies on manual operation in the front and back processing links, resulting in unstable repair quality, which will cause the overall performance to decline and the measured vibration amplitude to increase significantly, affecting the dynamic balance performance in subsequent use.

[0004] Moreover, as for the track wear of armored vehicles, since long-term continuous operation is often required, the damage rate of the entire track chain is 65%-80%, and more than 70% of the track chain damage is concentrated on 5-8 consecutive chain plates. If the above-mentioned method of disassembling and repairing the tracks in sections is adopted, the repair work of a single track will take a long time and the overall work efficiency will be low.

DETAILED DESCRIPTION

[0033] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0034] The following describes the armored vehicle track wear repair device based on laser cladding in accordance with an embodiment of the present application in conjunction with the accompanying drawings.

[0035] like Figure 1 As shown, the armored vehicle track wear repair device based on laser cladding of an embodiment of the present application may include a transmission device 100, a traction device 200, a longitudinal cleaning device 300, a preheating chamber 400, a slow cooling chamber 500, a post-processing component 600 and a laser cladding device 700.

[0036] The traction device 200 is disposed in the transmission device 100 , and the crawler chain 800 moves on the transmission roller 101 of the transmission device 100 through the traction of the traction device 200 .

[0037] The longitudinal cleaning device 300 , the preheating chamber 400 , the working end of the laser cladding equipment 700 , the slow cooling chamber 500 and the post-processing assembly 600 are sequentially arranged on the transmission device 100 in a transverse direction.

[0038] It should be noted that by pulling the entire track chain 800 by the traction device 200, the entire track chain 800 passes through the longitudinal cleaning device 300, the preheating chamber 400, the working end of the laser cladding equipment 700, the slow cooling chamber 500 and the post-processing component 600 in sequence, forming a complete operation line, thereby improving the overall repair efficiency.

[0039] Specifically, when the relevant staff repairs the track chain 800 , they hook the inner wall end of the track chain 800 onto the traction device 200 , and start the traction device 200 to drag the track chain 800 to move on the transmission roller 101 .

[0040] The crawler chain 800 first passes through the longitudinal cleaning device 300 on the transmission device 100. By longitudinally cleaning the crawler chain 800, its surface can be cleaned to remove oil, rust and attachments, ensuring the cleanliness of the subsequent cladding area.

[0041] The cleaned crawler chain plate 800 enters the preheating chamber 400, where the substrate temperature of the crawler chain plate 800 is increased by uniform heating, thereby reducing the thermal stress gradient during laser cladding and avoiding poor bonding between the cladding layer and the crawler chain plate 800 due to a large temperature difference.

[0042] The preheated track chain 800 moves to the working end of the laser cladding equipment 700, and the laser beam clads the alloy powder layer by layer in the worn area to form a high-density repair layer, thereby restoring the geometric dimensions and mechanical properties of the track chain 800.

[0043] The track chain plate 800 after cladding is put into the slow cooling chamber 500, and the repair layer and the substrate are cooled synchronously through programmed gradient cooling, thereby suppressing the generation of grain boundary cracks and optimizing the microstructure.

[0044] Finally, the track chain 800 passes through the post-processing assembly 600 to remove residual impurities on the surface, ensuring that the repaired surface meets the repair requirements.

[0045] It should be noted that the traction device 200 can adopt a step-by-step traction method, that is, periodic start and stop, so that the crawler chain 800 moves forward step by step according to a preset time interval or displacement interval, and completes specific process actions during the pause period, such as preheating, laser cladding, cooling and other processes.

[0046] In addition, the laser cladding equipment 700 can be operated by relevant staff to perform cladding repair work. A visual recognition system can also be set up to identify the wear position on the crawler chain 800 and control the robotic arm and cladding end of the laser cladding equipment 700 through a controller to achieve an automatic repair effect.

[0047] As a possible scenario, Figure 2 As shown, the post-processing assembly 600 includes an impact device 610 , a cleaning roller 620 , and an elastic hammer 630 .

[0048] Among them, the impact device 610 can be lifted and lowered reciprocatingly and is mounted above the transmission device 100. The rotating shaft 621 of the cleaning roller 620 is intermittently engaged with the driving end of the impact device 610 through the second intermittent gear 622, and a torsion spring 623 for resetting is provided on the rotating shaft 621. The elastic hammer 630 is set on the rotating shaft 621, so that when the impact end of the impact device 610 descends to impact the track chain 800, the cleaning roller 620 engages and rotates, causing the elastic hammer 630 to rotate and hammer the impact end of the impact device 610, thereby achieving a secondary impact on the track chain 800.

[0049] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 3 As shown, the impact device 610 includes a first intermittent gear 611 , a rack 612 , a limiting bar 613 , a connecting frame 614 , an impact head 615 , a column 616 and a tension spring 617 .

[0050] Among them, the first intermittent gear 611 can be rotatably set on the first mounting frame 601 on the side of the transmission device 100, and is connected to the adjacent transmission roller 101 through a sprocket. The rack 612 is slidably embedded in the vertically set limit bar 613 and intermittently meshes with the first intermittent gear 611.

[0051] The connecting frame body 614 is set on the rack 612, the impact head 615 is set at the bottom of the connecting frame body 614, the column 616 is set at the top of the rack 612 and passes through the top of the first mounting frame 601, the tension spring 617 is sleeved on the column 616, and the two ends of the tension spring 617 are respectively connected to the connecting head at the top of the column 616 and the top of the first mounting frame 601, wherein the first intermittent gear 611 is intermittently meshed with the second intermittent gear 622.

[0052] Specifically, when the post-processing component 600 processes the track chain 800 after cladding and cooling, first, the first intermittent gear 611 engages with the rack 612 under the drive of the transmission roller 101, and the rack 612 drives the connecting frame 614 and the impact head 615 to rise, and the tension spring 617 is stretched to store energy.

[0053] When the first intermittent gear 611 disengages from the rack 612, the tension spring 617 rebounds, causing the column 616 to drive the rack 612, the connecting frame 614 and the impact head 615 downward, and the impact head 615 impacts the surface of the track chain 800. The impact energy causes the cladding layer and the impurity layer on the surface of the cladding layer to be peeled off. At the same time, the impact vibration causes the internal residual stress in the cladding layer of the track chain 800 to be redistributed, thereby improving the overall fatigue resistance.

[0054] After the first intermittent gear 611 disengages from the rack 612 and engages with the second intermittent gear 622, the cleaning roller 620 rotates along with the rotating shaft 621. The bristles of the cleaning roller 620 remove slag, oxide scale and splashes on the surface of the track chain 800 during rotation. The rotating shaft 621 drives the elastic hammer 630 to hammer the connecting frame 614, causing the impact head 615 to impact the track chain 800 for the second time, further stripping off the cladding layer and impurity layer and eliminating the residual stress inside the cladding layer.

[0055] As the first gap gear continues to rotate, when the second intermittent gear 622 disengages from the first gap gear, the torsion spring 623 drives the cleaning roller 620 to rotate in the opposite direction, and the contact angle of the bristles of the cleaning roller 620 changes. The grooves and concave and convex surfaces of the track chain 800 are covered through the shear-peeling composite action, thereby improving the cleaning uniformity. At the same time, the elastic hammer 630 rotates in the opposite direction with the rotating shaft 621 and resets to the initial position to prepare for the next cycle.

[0056] When the first intermittent gear 611 is meshed with the rack 612 again, the tension spring 617 stores energy again, and the rack 612 drives the impact head 615 to return to the high position, entering the next impact cycle.

[0057] It should be noted that the elastic hammer 630 may include an elastic metal plate and a hammer head, one end of the elastic metal plate is set on the rotating shaft 621, and the hammer head is set at the other end of the elastic metal plate. The elastic metal plate can be driven to rotate by rotating the rotating shaft 621.

[0058] It is understandable that when the rotating shaft 621 rotates, the elastic metal plate is bent and deformed by the centrifugal force, storing elastic potential energy. When the hammer head contacts the connecting frame 614, the elastic metal plate rebounds quickly, releasing the stored energy and increasing the impact force.

[0059] In one embodiment of the present application, Figure 4 and Figure 5 As shown, the transmission device 100 is provided with transmission rollers 101 spaced side by side, and the transmission rollers 101 near the feed end are coaxially provided with elastic knocking structures 102 to knock the back of the crawler chain plates 800 .

[0060] The elastic striking structure 102 includes an elastic cord 1021 circumferentially arranged at equal angles at the rotating end of the transmission roller 101 and a striking head 1022 arranged on the elastic cord 1021 .

[0061] When the traction device 200 drags the track chain 800 to move, the track chain 800 can drive the transmission roller 101 to rotate, so that the elastic knocking structure 102 coaxially arranged with the transmission roller 101 works, that is, the elastic rope 1021 rotates with the corresponding transmission roller 101, and can drive the knocking head 1022 to rotate to knock on the track chain 800. The vibration generated by knocking on the back is transmitted to the front, causing impurities such as oxide scale and mud and sand attached to the surface of the positive track chain 800 to loosen and fall off, making it convenient for the subsequent longitudinal cleaning device 300 to clean the surface of the track chain 800.

[0062] It should be noted that although the entire track chain 800 will be pre-treated with water flushing to remove surface mud and dirt after being removed from the armored vehicle, the mud and sand in some gaps and the oxide scale on the surface cannot be effectively removed. Therefore, the elastic knocking structure 102 can make the impurities fall off, which is convenient for subsequent processing to ensure the surface cleanliness of the track chain 800 during cladding.

[0063] In one embodiment of the present application, Figure 6 As shown, the transmission device 100 is provided with a slide rail 103 along the discharging direction, and the traction end of the traction device 200 is movably provided in the slide rail 103. The traction device 200 includes a driving motor 210, a transmission structure 220 and a traction head 230.

[0064] Among them, the driving motor 210 is arranged on the transmission device 100, the transmission structure 220 is arranged in the transmission device 100 and connected to the output end of the driving motor 210, the traction head 230 is arranged on the transmission structure 220, and is movably arranged in the slide rail 103, and the traction head 230 is arranged between two rows of transmission rollers 101.

[0065] It should be noted that the transmission structure can be a synchronous belt structure or a sprocket structure.

[0066] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 7 As shown, the traction head 230 includes a traction plate 231 , a roller 232 , a fixing frame 233 , a rotating arm 234 and a damping knob 235 .

[0067] Among them, rollers 232 are provided at the corners of the traction plate 231, and the rollers 232 are embedded in the slide rail 103. The fixed frame 233 is provided at the bottom of the traction plate 231 and is connected to the transmission end of the transmission structure 220. The rotating arm 234 can be rotatably set on the traction plate 231 and locked by the damping knob 235. The end of the rotating arm 234 is detachably connected to the bottom of the crawler chain plate 800.

[0068] It should be noted that before repairing the track chain 800, the relevant staff will rotate the rotating arm 234 to an appropriate height, and then connect the end of the track chain 800 to the rotating arm 234 by bolt locking, and lock the damping knob 235. Then start the drive motor 210, and the drive motor 210 drives the transmission structure 220 to rotate, so that the traction plate 231 follows the movement. At the same time, the roller 232 rolls in the slide rail 103, so that the track chain 800 is pulled by the traction device 200 and moves on the transmission roller 101.

[0069] In one embodiment of the present application, Figure 8 and Figure 9 As shown, the longitudinal cleaning device 300 includes a track frame 310 , a cleaning brush 320 , an opening and closing structure 330 , a pushing frame 340 and a horizontal reciprocating structure 350 .

[0070] Among them, the track frame 310 is mounted above the transmission device 100 through the second mounting frame 301. Two symmetrical annular track grooves 311 are opened in the longitudinal direction of the track frame 310. Two cleaning brushes 320 are slidably set in the corresponding annular track grooves 311 through elastic heads (not marked in the figure). A guide part 312 is set at the arc position at the bottom of the annular track groove 311 away from the center of the transmission device 100 to guide the cleaning brush 320 to deviate upward.

[0071] It should be noted that the guide portion 312 is designed with a gradually changing slope height. When the cleaning brush 320 moves to the bottom arc, due to the existence of the guide portion 312, the elastic head is gradually compressed until the elastic head passes through the guide portion 312 and resets. At this time, due to the blocking effect of the guide portion 312, the elastic head on the cleaning brush 320 cannot be reset from the bottom of the annular track groove 311, and can only move along the top track of the annular track groove 311. Therefore, when the cleaning brush 320 is reset, the cleaning brush 320 can be separated from the contact with the surface of the track chain 800, thereby avoiding the impurities to be cleaned being brought to the middle of the track chain 800 due to the reset of the cleaning brush 320.

[0072] As a possible scenario, the elastic head includes two metal plates and a rubber pad arranged between the metal plates, one of the metal plates is connected to the end of the cleaning brush 320, and the other metal plate and the rubber pad are embedded in the annular track groove 311. When the elastic head is squeezed by the guide part 312, the rubber pad can be squeezed and deformed, and after the elastic head passes through the guide part 312, the rubber pad is restored.

[0073] The opening and closing structure 330 is arranged at the top of the second mounting frame 301, and the two opening and closing ends of the opening and closing structure 330 are respectively slidably connected to the two cleaning brushes 320, wherein when the opening and closing ends slide horizontally on the cleaning brush 320, they can slide vertically with the cleaning brush 320.

[0074] It should be noted that when the opening and closing end pushes the cleaning brush 320 outward, the opening and closing end slides horizontally on the cleaning brush 320, and when the opening and closing end pulls the cleaning brush 320 inward to reset it, the cleaning brush 320 moves upward due to the guiding effect of the guide part 312. At this time, the opening and closing end can slide vertically with the cleaning brush 320.

[0075] The driving end of the horizontal reciprocating structure 350 is connected to the rotating end of the adjacent transmission roller 101, and the pushing frame 340 is set on the reciprocating end of the horizontal reciprocating structure 350, and the pushing frame 340 is connected to the opening and closing driving end of the opening and closing structure 330 through the laterally arranged pushing rod 341, so that the reciprocating motion of the horizontal reciprocating structure 350 drives the opening and closing structure 330 to perform the opening and closing action through the pushing frame 340.

[0076] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 10 As shown, a slide frame 321 is provided on the side of the cleaning brush 320 away from the center of the transmission device 100, and a sliding sleeve 322 is provided in the slide frame 321 for sliding connection. A sliding rod 3301 is provided at the opening and closing end of the opening and closing structure 330, and the sliding rod 3301 passes through the sliding sleeve 322 and extends downward, and an extrusion spring 3302 is provided on the sliding rod 3301.

[0077] It should be noted that when the cleaning brush 320 moves from the top of the annular rail groove 311 to the side away from the guide portion 312, the cleaning brush 320 moves downward along the annular rail groove under the reset action of gravity and the extrusion spring 3302, so that when the cleaning brush 320 is pushed outward subsequently, it can clean the impurities on the track chain 800.

[0078] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 8 As shown, the horizontal reciprocating structure 350 includes a rotating disk 351 , a limiting head 352 , a sliding frame 353 and an extension rod 354 .

[0079] Among them, the rotating disk 351 is coaxially connected to the adjacent transmission roller 101, the limit head 352 is eccentrically set on the rotating disk 351, the sliding frame 353 is a vertical long strip, and the limit head 352 is embedded in the sliding frame 353, and extension rods 354 are respectively provided on both sides of the sliding frame 353. The extension rods 354 are slidably connected to the limit rod sleeve 3011 on the second mounting frame 301, wherein the pushing frame 340 is connected to the extension rod 354.

[0080] To clearly illustrate the above embodiment, in one embodiment of the present application, Figure 11 As shown, the opening and closing structure 330 includes a top plate 331 , a connecting rod 332 and an opening and closing rod 333 .

[0081] Among them, the top plate 331 is horizontally arranged on the top of the second mounting frame 301, and a slot is opened on the top plate 331 for one end of the connecting rod 332 to slide. The adjacent rod ends of the two opening and closing rods 333 are respectively engaged through gears, and the other end of the connecting rod 332 is hinged to one of the opening and closing rods 333.

[0082] The pushing rod 341 on the pushing frame 340 is connected to the end of the connecting rod 332 sliding in the slot.

[0083] Specifically, when the transmission roller 101 drives the rotating disk 351 to rotate, the eccentric movement of the limiting head 352 pushes the sliding frame 353 to move laterally, and the extension rod 354 drives the pushing frame 340 to move back and forth laterally.

[0084] When the pushing frame 340 pushes the connecting rod 332 through the pushing rod 341, the connecting rod 332 slides along the groove of the top plate 331 and pushes the opening and closing rod 333 to rotate outward around the gear meshing point, and the two opening and closing rods 333 push the cleaning brush 320 to move outward to clean impurities on the surface of the crawler chain 800.

[0085] As the opening and closing rod 333 pushes, the cleaning brush 320 drives the elastic head to move in the annular track groove 311 until it is blocked by the inclined surface of the guide part 312. After being compressed, the elastic head passes through the guide part 312.

[0086] During resetting, the pushing frame 340 pulls back the connecting rod 332 through the pushing rod 341, driving the opening and closing rod 333 to rotate inward, and the distance between the two cleaning brushes 320 is reduced, so that the cleaning brush 320 is forced to rise upward along the annular track groove 311, and the bristles of the cleaning brush 320 are separated from the chain plate surface and reset. After resetting, when the cleaning brush 320 passes through the arc structure on the other side of the annular track groove 311, it is subjected to the dual action of gravity and the extrusion spring 3302, pressing the cleaning brush 320 down to the bottom of the annular track groove 311. At this time, the opening and closing structure 330 has completed its contraction and is waiting for the horizontal reciprocating structure 350 to open and close again through the pushing frame 340.

[0087] In one embodiment of the present application, the preheating chamber 400 and the slow cooling chamber 500 both include a chamber and heating wires, and the heating wires are arranged along the inner wall of the chamber.

[0088] It should be noted that before laser cladding, when the track chain plate 800 passes through the preheating chamber 400, the electric heating wire radiates and heats its surface temperature. After the temperature of the track chain plate 800 rises, the temperature difference between the track chain plate 800 and the cladding layer decreases during laser cladding, which can suppress cracks in the cladding layer. In addition, the preheating of the track chain plate 800 can accelerate the rupture of the surface oxide film, expose the fresh metal interface, and improve the bonding strength of the cladding layer.

[0089] After cladding, the crawler chain plate 800 enters the slow cooling chamber 500, and the electric heating wire controls the cooling process at a programmed cooling rate, which can promote the transformation of the austenite in the cladding layer into fine-grained martensite, improve the hardness of the repaired connection, and reduce residual stress.

[0090] In summary, according to the armored vehicle track wear repair device based on laser cladding of the embodiment of the present application, a closed-loop production line is formed by integrating a longitudinal cleaning device 300, a preheating chamber 400, a laser cladding device 700, a slow cooling chamber 500 and a post-processing component 600 on the transmission device 100. A single operation can cover all repair processes, which not only reduces manual intervention, but also improves the repair quality and ensures the overall performance of the track chain 800; through the coordinated action of the traction device 200 and the transmission device 100, the transmission and positioning of the entire track chain 800 are realized, and repair can be carried out without disassembling a single chain plate, thereby improving the overall repair efficiency.
