Description

Technical Field

[0001] The utility model belongs to the technical field of oil pipe protection, in particular to a protection device for an oil cylinder pipeline. Background Art

[0002] In a hydraulic system, the oil cylinder and oil pipe are two indispensable components of the hydraulic system. They are closely connected and play a vital role in mechanical equipment. The oil pipe transports the oil generated by the hydraulic pump to the oil cylinder. The oil pressure acts on the piston of the oil cylinder, pushing the piston to move the oil cylinder, converting hydraulic energy into mechanical energy, thereby realizing various mechanical actions. Therefore, the quality and performance of the oil pipe directly affect the working effect of the oil cylinder and the overall performance of the hydraulic system. There is currently a one-piece oil cylinder, in which the oil cylinder and oil pipe are integrally molded. This ensures good sealing between the oil cylinder and oil pipe, and reduces the risk of leakage. However, in this design, the oil pipe cannot be removed from the oil cylinder, so it is easily damaged by factors such as collisions during transportation. Utility Model Content

[0003] The purpose of the present utility model is to provide a protection device for an oil cylinder pipeline, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0004] A protective device for an oil cylinder pipeline comprises a cylinder barrel, an oil pipe shield and a compression screw, wherein a pad is fixedly mounted on the outer wall of the cylinder barrel, a compression block is provided on the side of the pad away from the cylinder barrel, the oil pipe shield is sleeved outside the compression block and the pad, locking parts are provided on both sides of the oil pipe shield, a limiting cavity is fixedly mounted on the outer wall of the cylinder barrel, the limiting cavity corresponds to the position of the locking part, a through opening is formed on the limiting cavity, the compression screw passes through the locking part and the through opening of the limiting cavity and extends into the limiting cavity, and a limiting block is provided on the end of the compression screw extending into the limiting cavity;

[0005] One end of the compression screw away from the limiting cavity is fixedly connected to a rotating block, and a strong spring is also sleeved on the compression screw, and the strong spring is arranged between the rotating block and the locking portion.

[0006] The pressing screw is sleeved with an adjusting nut, which is arranged between the rotating block and the strong spring.

[0007] A screw hole is provided on the surface of the pad block opposite to the pressure block, and a stepped through hole corresponding to the screw hole is provided on the surface of the pressure block opposite to the pad block. The limiting screw passes through the stepped through hole and is assembled in the screw hole.

[0008] The portion of the pressing block close to the cushion block and the portion of the cushion block close to the pressing block are both soft layers.

[0009] The portion of the pressing block away from the cushion block and the portion of the cushion block away from the pressing block are both hard layers.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This solution installs a pad on the oil cylinder, sets a pressure block on the pad, places the entire oil pipe between the pad and the pressure block, and puts on the oil pipe cover. The oil pipe cover is fixed to the oil cylinder by the compression screw. The oil pipe cover can play a protective role to prevent the oil pipe from being damaged by collision with other objects during transportation. The pad and the pressure block will compress the oil pipe to prevent the oil pipe from shaking due to vibration during transportation and colliding with the inner wall of the oil pipe cover to cause damage.

[0012] 2. This solution adds a limit cavity to the oil cylinder, and passes through the locking parts on both sides of the oil pipe shield through a tightening screw, and extends into the limit cavity. Then, the tightening screw is rotated so that the two ends of the limit blocks at the end of the tightening screw are stuck to the opening of the limit cavity. The strong spring set on the tightening screw will press the limit part of the oil pipe shield toward the oil cylinder, so that the inner wall of the oil pipe shield will squeeze the pressure block onto the pad, and then compress the oil pipe between the pad and the pressure block; this design makes it very convenient to disassemble and assemble the oil pipe on the protective device, without the need for tools and cumbersome operations. Only the tightening screw needs to be rotated to make the two ends of the limit block engage with the entrance of the limit cavity or release the limit, thereby fixing or removing the oil pipe shield.

[0013] 3. Since this solution uses the force provided by a strong spring for fixation, and the spring is elastic, this solution can adapt to oil pipes of different diameters and can stabilize and protect oil pipes of different specifications without the need for other adaptive modifications.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4As shown in the embodiment of the present invention, a protective device for an oil cylinder pipeline includes a cylinder barrel 1, an oil pipe shield 201 and a compression screw 404. A pad 302 is fixedly installed on the outer wall of the cylinder barrel 1. A pressure block 301 is provided on the side of the pad 302 away from the cylinder barrel 1. The oil pipe shield 201 is sleeved on the pressure block 301 and the pad 302. Locking parts 202 are provided on both sides of the oil pipe shield 201. A limited cavity 5 is fixedly installed on the outer wall of the cylinder barrel 1. The limited cavity 5 and the locking part 202 are fixedly installed on the outer wall of the cylinder barrel 1. The position of the tightening part 202 corresponds to that of the limit cavity 5, and a through opening is opened on the limit cavity 5. The clamping screw 404 passes through the locking part 202 and the through opening of the limit cavity 5 and extends into the limit cavity 5. A limit block 405 is provided at one end of the clamping screw 404 extending into the limit cavity 5. The end of the clamping screw 404 away from the limit cavity 5 is fixedly connected to the rotating block 401. A strong spring 403 is also installed on the clamping screw 404, and the strong spring 403 is arranged between the rotating block 401 and the locking part 202. Place the entire oil pipe 304 between the pressure block 301 and the cushion block 302, and put on the oil pipe shield 201, extend the limit block 405 at the end of the pressing screw 404 into the limit cavity 5, rotate the pressing screw 404, so that the two ends of the limit block 405 are clamped in the through opening of the limit cavity 5, and the strong spring 403 will push the oil pipe shield 201 toward the cylinder 1, thereby fixing the oil pipe shield 201 on the cylinder 1. The oil pipe shield 201 can protect the oil pipe 304 to prevent damage caused by collision during transportation. The thrust of the strong spring 403 , the oil pipe shield 201 will press the pressure block 301 onto the cushion block 302, thereby stabilizing the oil pipe 304 between the pressure block 301 and the cushion block 302, and preventing the oil pipe 304 from colliding with the inner wall of the oil pipe shield 201 and causing damage due to vibration generated during transportation. If disassembly is required, rotate the tightening screw 404 so that the two ends of the limit block 405 are no longer stuck with the opening of the limit cavity 5, and then the tightening screw 404 can be taken out from the limit cavity 5, and then the oil pipe shield 201 can be removed to release the oil pipe 304 from the clamped and fastened state.

[0023] It should be noted that, since the above design uses a strong spring 403 to provide force to clamp and stabilize the oil pipe 304, the elastic force of the spring enables the design to match oil pipes of different diameters without the need for other adaptive modifications.

[0024] In one embodiment, see Figure 2 As shown, the clamping screw 404 is provided with an adjusting nut 402, which is arranged between the rotating block 401 and the strong spring 403. By rotating the adjusting nut 402, the elastic force of the strong spring 403 can be adjusted. The elastic force can be flexibly adjusted according to the diameter of the oil pipe 304, so that the clamping can be made more stable without damaging the oil pipe 304.

[0025] In one embodiment, see Figure 2As shown, a screw hole is provided on the surface of the pad 302 on the side opposite to the pressure block 301, and a stepped through hole corresponding to the screw hole is provided on the surface of the pressure block 301 on the side opposite to the pad 302. After the oil pipe 304 is placed on the pad 302, the pressure block 301 is covered, and a limiting screw 303 is passed through the stepped through hole and assembled in the screw hole to limit the position and prevent the pressure block 301 and the pad 302 from being misaligned when clamped.

[0026] In one embodiment, see Figure 4 As shown, the portion of the pressure block 301 close to the cushion block 302 and the portion of the cushion block 302 close to the pressure block 301 are both soft layers 305. When the pressure block 301 and the cushion block 302 clamp the oil pipe 304, the two soft layers 305 will be forced to sink inward and thus wrap around the oil pipe 304, making the clamping more stable. The soft layers 305 can also reduce the probability of the oil pipe 304 being damaged due to excessive clamping force.

[0027] In one embodiment, see Figure 4 As shown, the portion of the pressing block 301 away from the cushion block 302 and the portion of the cushion block 302 away from the pressing block 301 are both hard layers 306. Since the hard layer 306 is provided at the supporting and force-bearing position, the hard material makes the force-bearing strength higher.

[0028] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
