[0002] When disassembling and decomposing the hydraulic cylinders in existing mining engineering machinery and equipment, the main method is on-site disassembly. After the hydraulic cylinder is disassembled from the main body of the equipment, the cylinder will be disassembled and placed on the ground before further disassembly. The disassembly process mainly involves first fixing the cylinder barrel of the hydraulic cylinder, then using a wire rope to fix it with the piston rod of the hydraulic cylinder, and then using a forklift to pull the piston rod out of the cylinder barrel. However, when the hydraulic cylinder is disassembled on the ground, the oil inside it is easy to flow to the ground and cause pollution to the ground. When a forklift is used to drag during disassembly, the force cannot be controlled, which can easily cause scraping between the piston rod and the cylinder barrel inside the cylinder, resulting in damage to the cylinder body.

[0003] Based on the above situation, it is necessary to design a hydraulic cylinder disassembly device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0024] Reference Figures 1-8 As shown, a hydraulic cylinder disassembly device includes a support frame 1, and four support legs 16 are fixedly connected to the bottom of the support frame 1. The four support legs 16 stably lift the support frame 1 to a certain height, which is convenient for the operator to disassemble the hydraulic cylinder body 3. The length setting of the support frame 1 should be designed according to the length of the hydraulic cylinder body 3 to be disassembled. The length of the support frame 1 should be greater than twice the length of the hydraulic cylinder body 3, so as to ensure the subsequent disassembly operation of the hydraulic cylinder body 3.

[0025] It also includes: a placement plate 2 connected to the support frame 1, a fixing component, a traction mechanism 6 and a collection box 7, wherein there are several placement plates 2 and they are all connected to the support frame 1. The placement plates 2 are used to carry the hydraulic cylinder body 3. When the hydraulic cylinder body 3 is placed on several placement plates 2, a part of the placement plates 2 will carry the cylinder barrel 5 on the hydraulic cylinder body 3, and the other part of the placement plates 2 will carry the piston rod 4 on the hydraulic cylinder body 3. The two placement plates 2 support the hydraulic cylinder body 3, so that the hydraulic cylinder body 3 is more stable when placed.

[0026] After the hydraulic cylinder body 3 is placed on the placement plate 2, the fixing assembly is used to connect the cylinder barrel 5 on the hydraulic cylinder body 3 to the support frame 1, so that when the piston rod 4 on the hydraulic cylinder body 3 is pulled later, the hydraulic cylinder body 3 can remain stable under the action of the cylinder barrel 5 being fixed.

[0027] While the fixing assembly fixes the cylinder barrel 5 on the hydraulic cylinder body 3, the output end of the traction mechanism 6 is connected to one end of the piston rod 4 on the hydraulic cylinder body 3 and is used to pull the piston rod 4 on the hydraulic cylinder body 3. The traction mechanism 6 is used to pull the piston rod 4 on the hydraulic cylinder body 3, and the piston rod 4 is gradually stretched out from the inside of the cylinder barrel 5 until it is separated from the cylinder barrel 5.

[0028] The above-mentioned traction mechanism 6 is a mechanical equipment with existing technology. The traction mechanism 6 can be a traction device such as a hand hoist, a winch, a pulley block, a traction rope, etc. According to the actual situation, a suitable traction mechanism 6 device is selected. Its main purpose is to be able to stretch and pull the piston rod 4 on the hydraulic cylinder body 3 smoothly and slowly, eliminating the damage to the oil cylinder caused by sudden force. At the same time, personnel working on the support frame 1 can reduce the safety risks in the process.

[0029] After the piston rod 4 on the hydraulic cylinder body 3 is separated from the cylinder barrel 5, oil will flow down between the two as they separate, and a collection box 7 is provided below where the oil falls. The collection box 7 is installed on the support frame 1 and is located below the placement plate 2, and the collection box 7 is used to collect the oil that falls when the hydraulic cylinder body 3 is disassembled. The collection box 7 can be removed from the support frame 1 later, and the oil inside the collection box 7 can be collected and recycled. The hydraulic cylinder body 3 can be placed on the support frame 1 for disassembly, which can effectively avoid environmental pollution caused by the outflow of oil during the process. Secondly, using this technical solution to disassemble the hydraulic cylinder body 3 can reduce the labor intensity caused by disassembly by multiple people, and one person can complete the corresponding maintenance, thereby improving the utilization rate of personnel.

[0030] Reference Figure 1 as well as Figure 3-4 As shown, further, several placement plates 2 are placed at equal distances from each other, and a part of the placement plates 2 are provided with a placement groove 1 8, and another part of the placement plates 2 are provided with a placement groove 2 9. The placement groove 1 8 is used to support and stabilize the cylinder barrel 5 on the hydraulic cylinder body 3, and the placement groove 2 9 is used to support and stabilize the piston rod 4 on the hydraulic cylinder body 3. The placement plates 2 at two positions support the hydraulic cylinder body 3, and then cooperate with the placement groove 1 8 and the placement groove 2 9 to support the piston rod 4 and the cylinder barrel 5 on the hydraulic cylinder body 3, so that the hydraulic cylinder body 3 is more stable when placed.

[0031] Among them, the first implementation scheme of the placement groove 1 8 and the placement groove 2 9 in the utility model is that the shapes of the placement groove 1 8 and the placement groove 2 9 are semicircular corresponding to the outer surfaces of the cylinder barrel 5 on the hydraulic cylinder body 3 and the piston rod 4 on the hydraulic cylinder body 3. When the hydraulic cylinder body 3 is placed on the placement plate 2, the semicircular placement groove 1 8 and the placement groove 2 9 will respectively support and stabilize the cylinder barrel 5 and the piston rod 4 on the hydraulic cylinder body 3, so that the hydraulic cylinder body 3 will not shake easily.

[0032] Among them, the second implementation scheme of the placement groove 1 8 and the placement groove 2 9 in the present invention is that the shapes of the placement groove 1 8 and the placement groove 2 9 are respectively V-shaped, which are in contact with the outer surfaces of the cylinder barrel 5 on the hydraulic cylinder body 3 and the piston rod 4 on the hydraulic cylinder body 3. When the hydraulic cylinder body 3 is placed on the placement plate 2, the V-shaped placement groove 1 8 and the placement groove 2 9 will respectively support and stabilize the cylinder barrel 5 and the piston rod 4 on the hydraulic cylinder body 3, so that the hydraulic cylinder body 3 will not shake easily.

[0033] The advantage of the second embodiment of the placement groove 1 8 and the placement groove 2 9 in the present invention compared to the first embodiment is that the V-shaped placement groove 1 8 and the placement groove 2 9 can adapt to hydraulic cylinder bodies 3 of different sizes and have a wide range of uses, while the semicircular placement groove 1 8 and the placement groove 2 9 can only adapt to hydraulic cylinder bodies 3 of a certain size and have certain limitations.

[0034] Reference Figure 8 As shown, further, the fixing assembly includes a cylindrical pin 17 and a pin plate 10 and a pin plate 2 11 fixedly connected to the support frame 1, and circular holes 12 are provided on the pin plate 10 and the pin plate 2 11. The pin plate 10 and the pin plate 2 11 are located directly below the pin plate 10 and a distance is left between the two. The axis of the circular hole 12 on the pin plate 10 is collinear with the axis of the circular hole 12 on the pin plate 2 11. One end of the cylindrical pin 17 passes through the two circular holes 12 and extends from the side of the pin plate 2 11 away from the pin plate 10. The other end of the cylindrical pin 17 is provided with a limit plate 13. Plate 13 is in movable contact with the side of pin plate 10 away from pin plate 2 11. When in use, when the hydraulic cylinder body 3 is placed on the placement plate 2, the tail end of the cylinder barrel 5 on the hydraulic cylinder body 3 is placed corresponding to the circular hole 12, and then the cylindrical pin 17 is inserted from the circular hole 12 on pin plate 10, and then the cylindrical pin 17 passes through the tail end of the cylinder barrel 5, and finally inserted into the circular hole 12 on pin plate 2 11. At this time, the hydraulic cylinder body 3 is connected to the support frame 1. At this time, when the hydraulic cylinder body 3 is pulled, the cylindrical pin 17 will prevent the hydraulic cylinder body 3 from being pulled.

[0035] Reference Figure 7As shown, finally, a protective plate 14 is provided on the collection box 7, and a plurality of through slots 15 are opened on the protective plate 14. The protective plate 14 is movably mounted on the collection box 7. The protective plate 14 prevents parts from falling into the collection box 7 along with the oil, and the opening of the through slots 15 only allows the oil to fall into the collection box 7, which facilitates the subsequent cleaning and recovery of the oil.
