Abstract
Description
Technical Field
[0001] This utility model application relates to the field of tank repair equipment technology, specifically to a clamp for tank repair. Background Technology
[0002] In the maintenance of tank track systems, track pins are a key component, responsible for connecting the various parts of the track chain to ensure the stability and durability of the track. Track pins are generally embedded in the track chain and are often subjected to great pressure and friction due to the harsh working environment. Tank maintenance jigs are used for the maintenance of track systems to improve maintenance efficiency and ensure the normal operation of the track system.
[0003] Chinese Patent Publication No. CN221023931U discloses a track pin disassembly fixture for tanks, comprising: a hydraulic cylinder; a connecting seat, the connecting seat including a connecting plate, the connecting plate being vertically folded to form an extension plate, the connecting plate being fixedly sleeved on one end of the piston rod of the hydraulic cylinder, and the connecting plate having a through hole for the piston rod to pass through; and a clamping plate, the clamping plate being fixedly disposed on the end of the extension plate away from the hydraulic cylinder by a fastening plate and several bolts. The end of the hydraulic cylinder near the extended piston rod protrudes outward to form a connecting platform, the outer periphery of which is provided with external threads. This fixture can be used for disassembling tank track pins. The overall structure of this disassembly fixture is simple, space-saving, portable, and suitable for field use.
[0004] The aforementioned patent mentions that when disassembling track pins, it is necessary to clamp and fix the clamping plate to the gap between two adjacent track plates. Then, the hydraulic cylinder is activated to provide hydraulic power, thereby pushing out the track pins to achieve disassembly. During tank operation, the tracks are frequently subjected to ground impacts, which will generate instantaneous alternating stress on the adjacent track plates. The track pins and pin holes are prone to local plastic deformation under impact loads, resulting in an expansion of the mating gap. This makes it difficult to stably clamp the clamping plate to the gap between the two adjacent track plates, making it difficult for the track pin disassembly jig to stably push out the track pins, thereby reducing the disassembly efficiency of the track pin disassembly jig. Therefore, we propose a jig for tank maintenance. Utility Model Content

[0014] The advantages of this utility model application compared to the prior art are:
[0015] 1.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.
[0026] See Figures 1-2 As shown, a tank maintenance clamp includes a power component 1. A fixed frame 11 is provided at one end of the power component 1. Connecting frames 12 slide through both ends of the fixed frame 11, and a ring frame 13 is provided at one end of the connecting frame 12. The ring frame 13 is sleeved with the end of the power component 1 away from the fixed frame 11. A clamping plate 2 is provided at the end of the connecting frame 12 away from the ring frame 13. An adjustment mechanism for adjusting the position of the clamping plate 2 on the outside of the tank track is provided between the power component 1 and the ring frame 13. A positioning mechanism for driving the clamping plate 2 to clamp the tank track is provided on the connecting frame 12. The positioning mechanism is provided with a mechanism for mitigating impact. A buffer mechanism to prevent damage to clamp 2 from impact; an adjustment mechanism including two locking mechanisms, two displacement mechanisms, a transmission mechanism, and two guide mechanisms; the locking mechanisms are set on the power component 1 and the ring frame 13, and are used to restrict the ring frame 13 to the outside of the power component 1; the displacement mechanisms are set between the ring frame 13 and the locking mechanisms, and are used to drive the locking mechanisms to perform linear motion; the transmission mechanism is set on the displacement mechanisms, and is used to synchronously drive the two displacement mechanisms to move; the guide mechanisms are set on the power component 1 and the ring frame 13, and are used to assist the ring frame 13 in performing linear movement.
[0027] Specifically, the power component 1 uses a hydraulic cylinder as the implementing element.
[0028] When operating the tank maintenance fixture, the adjusting mechanism drives the ring frame 13 to move linearly along the outside of the power unit 1. The ring frame 13 drives the connecting frame 12 to move along the fixed frame 11, causing the connecting frame 12 to bring the clamping plate 2 closer to the track. Maintenance personnel can adjust the position of the clamping plate on the outside of the track, moving it above the anti-slip groove on the outside of the track. Then, the positioning mechanism drives the clamping plate to clamp the track, aligning it with the anti-slip groove. Simultaneously, the output end of the power unit 1 is aligned with the track pin, and the power unit 1 is activated. The output end of the power unit 1 pushes the track pin out of the track. By adjusting the position of the clamping plate 2 on the outside of the track, this fixture can adapt to different track deformation conditions, facilitating rapid tank track maintenance.
[0029] See Figure 1 , Figure 2 and Figures 4-7 As shown, the snap-fit mechanism includes a toothed plate 21 and a toothed block 22; the toothed plate 21 is connected to the power component 1; the toothed block 22 is mated with the toothed plate 21; the displacement mechanism includes a connecting pipe 23, a first screw 24, a first slider 25, and a first sliding groove 26; the connecting pipe 23 is connected to the toothed block 22; the first screw 24 is rotatably mounted on the connecting frame 12, and the first screw 24 is threadedly connected to the connecting pipe 23; the first slider 25 is connected to the connecting pipe 23; the first sliding groove 26 is opened on the side of the ring frame 13 near the first slider 25, and the first sliding groove 26 is used to cooperate with the first slider 25 for linear movement; the transmission mechanism includes a first cone The system includes a gear 27, a second bevel gear 28, and a handwheel 29. The first bevel gear 27 is rotatably mounted on the connecting frame 12 and is connected to the first screw 24. The second bevel gear 28 is rotatably mounted on the connecting frame 12 and meshes with the first bevel gear 27. The handwheel 29 is rotatably mounted on the connecting frame 12 and is connected to the second bevel gear 28. The guiding mechanism includes a guide block 210 and a guide rail plate 211. The guide block 210 is connected to the ring frame 13. The guide rail plate 211 is connected to the power component 1 and is used to cooperate with the guide block 210 for linear movement.
[0030] Specifically, the toothed plate 21 meshes with the toothed block 22. The first slider 25 forms a sliding fit with the first sliding groove 26. The first bevel gear 27 meshes with the second bevel gear 28. The guide block 210 slides with the guide rail plate 211.
[0031] During tank maintenance, the handwheel 29 rotates, driving the second bevel gear 28 to rotate. Through the meshing transmission between the first bevel gear 27 and the second bevel gear 28, the two first bevel gears 27 are synchronously driven to rotate, thereby causing each first screw 24 to rotate. Because the first slider 25 slides against the first groove 26, the connecting pipe 23 is prevented from rotating with the first screw 24. Since the connecting pipe 23 is threaded to the first screw 24, as it moves along the first screw 24, it causes the two toothed blocks 22 to disengage from the toothed plate 21. At this time, the maintenance personnel push the ring frame 13 to move outside the power component 1. The ring frame 13 drives the guide block 210 to slide along the groove of the guide rail plate 211. Because the guide block 210 slides against the guide rail plate 211, the ring frame 13's movement suppresses swaying and offset, stably driving the connecting frame 12 to move the clamping plate 2 above the track anti-slip groove. Adjust the power component 1 so that its output end aligns with the track pin. Then, rotate the handwheel 29 in the opposite direction to cause the first screws 24 to rotate in the opposite direction. The connecting pipe 23 drives the toothed block 22 to engage with the toothed plate 21, thus limiting and fixing the toothed block 22 and the toothed plate 21. This keeps the movement distance of the clamping plate 2 constant, improving the adaptability of the clamp to deformable tracks. This allows the tank maintenance clamp to effectively avoid instability caused by local plastic deformation of the track pin and pin hole under impact load, thereby improving the disassembly efficiency of the tank maintenance clamp.
[0032] See Figures 1-3 and Figure 6 As shown, the positioning mechanism includes a connecting plate 212, a second screw 213, and a slide rod 214; the connecting plate 212 is disposed at one end of the connecting frame 12; one end of the second screw 213 passes through the upper and lower sides of the connecting frame 12 and is rotatably disposed on the connecting plate 212, and the second screw 213 is threadedly connected to the connecting frame 12; one end of the slide rod 214 slides through the upper and lower sides of the connecting frame 12 and is connected to the connecting plate 212.
[0033] Specifically, the slide rod 214 and the connecting frame 12 form a sliding fit.
[0034] After the clamping plate 2 is adjusted to its position on the outside of the track, the second screw 213 is rotated. Since the second screw 213 is threadedly connected to the connecting frame 12, the second screw 213 pushes the connecting plate 212 downward. At the same time, the connecting plate 212 drives the sliding rod 214 downward along the connecting frame 12. Through the sliding engagement between the sliding rod 214 and the connecting frame 12, the connecting plate 212 can move downward stably without rotating with the second screw 213. This causes the connecting plate 212 to bring the clamping plate 2 closer to and clamp the anti-slip groove of the track, thus locking the clamping plate 2 into place with the track. At this time, the power unit 1 is activated. The output end of the power unit 1 pushes the track pin, completing the ejection operation of the track pin.
[0035] See Figure 3 and Figure 6As shown, the buffer mechanism includes a second slider 215, a second slide groove 216, and an elastic reset member 217; the second slider 215 is connected to the clamping plate 2; the second slide groove 216 is opened on the side of the connecting plate 212 near the second slider 215, and the second slide groove 216 is used to cooperate with the second slider 215 to move linearly; the elastic reset member 217 is disposed in the second slide groove 216, and the two ends of the elastic reset member 217 are respectively connected to the second slide groove 216 and the second slider 215.
[0036] Specifically, the second slider 215 and the second groove 216 form a sliding fit. The elastic reset element 217 uses a spring as the implementing element.
[0037] After the clamping plate 2 is engaged and limited with the track, the power unit 1 is activated. When the output end of the power unit 1 presses against the track pin, the clamping plate 2 and the anti-slip groove of the track are pressed against each other by the reaction force of the power unit 1. At this time, the clamping plate 2 drives the second slider 215 to slide along the second slide groove 216. Since the second slider 215 and the second slide groove 216 form a sliding fit, the second slider 215 can move stably along the second slide groove 216, thereby suppressing the swaying and deviation of the clamping plate 2 during movement. At the same time, the second slider 215 presses the elastic reset member 217 to make it contract. The elastic reset member 217 can buffer the impact force of the power unit 1 on the clamping plate 2 and prevent damage to the clamping plate 2.
[0038] Working principle: When the tank maintenance clamp is put into use, rotate the handwheel 29 to disengage the ring frame 13 from its limit position, adjust the position of the clamp 2 on the outside of the track, and restrict the adjusted position of the clamp 2. Then, rotate the second screw 213 to move the clamp 2 down and clamp it with the anti-slip groove of the track, and activate the power component 1 to push out the track pin. During the process of the power component 1 pushing out the track pin, the clamp 2 drives the second slider 215 to squeeze the elastic reset component 217, so that the elastic reset component 217 can buffer the impact force of the power component 1 on the clamp 2 and prevent the clamp 2 from being damaged.
[0039] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
