Description

Technical Field

[0001] The utility model discloses an anti-corrosion structure with a long protection period, belonging to the field of anti-corrosion equipment for disc spring support and hanger brackets. Background Art

[0002] Disc springs are the main components of variable disc spring supports and hangers, and are often installed on large equipment as powerful buffers and vibration damping springs. The disc spring body is composed of multiple disc spring discs, and there are many gaps between the spring discs, which is not conducive to anti-corrosion treatment after installation. Although some anti-corrosion treatment is performed on the surface before the spring is installed, it will face industrial atmospheric corrosion, electrochemical corrosion, crevice corrosion, etc. during service, which will cause corrosion damage to the spring discs of the spring body. As the corrosion damage further expands, if effective protection is not carried out, it will seriously affect the overall buffering and shock absorption effect of the spring.

[0003] In the prior art, multiple layers of anti-corrosion coatings are sprayed on the outside of each part of the disc spring support and hanger for anti-corrosion protection. The anti-corrosion coatings can only provide individual anti-corrosion protection for the parts. Due to friction between the parts during the operation of the disc spring support and hanger, the coating is scratched. The top end of the spring rod of the disc spring support and hanger is facing in the direction, and there is a gap at the connection, which makes it easy for external water to enter the interior of the disc spring support and hanger through the connection gap, causing the interior of the disc spring support and hanger to be in a humid environment for a long time, reducing the anti-corrosion effect.

[0004] In summary, the utility model therefore provides an anti-corrosion structure with a long protection period to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an anti-corrosion structure with a long protection period, so as to solve the problem of poor anti-corrosion effect caused by wear of the anti-corrosion coating proposed in the above background technology.

[0012] Furthermore, one end of the air outlet pipe away from the telescopic rubber airbag is installed in a downwardly inclined state, and a one-way valve is installed on the air outlet pipe.

[0013] Beneficial effects of the utility model:

[0014] During the extension and retraction work of the spring rod on the top of the disc spring support and hanger body, the mounting block can be driven to move up and down, and the telescopic rubber airbag covering the spring rod and the top of the disc spring support and hanger body can be squeezed and stretched, and air is sucked and exhausted through the air inlet pipe and the air outlet pipe to ensure that the telescopic rubber airbag can be used normally as the spring rod inside the disc spring support and hanger body is extended and retracted. The telescopic rubber airbag can cover the connection between the spring rod and the disc spring support and hanger body, effectively improving the anti-corrosion effect inside the disc spring support and hanger body.

[0015] By holding the swivel and rotating the second connecting ring in the opposite direction, the second connecting ring moves upward while rotating to disconnect the connection with the swivel, and then the first connecting ring is rotated in the opposite direction, so that the first connecting ring can be removed from the outside of the mounting ring, and then the telescopic rubber airbag can be removed from the outside of the spring rod as a whole from bottom to top, and the anti-corrosion structure can be replaced, which effectively improves the convenience of replacing the anti-corrosion structure and extends the life of the anti-corrosion protection effect of the disc spring support bracket.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1-4The utility model provides a technical solution: an anti-corrosion structure with a long protection period, including a disc spring support and hanger body 1 and a spring rod 2, the top of the disc spring support and hanger body 1 is fixedly connected with a mounting ring 5, the outside of the mounting ring 5 and located at the top of the disc spring support and hanger body 1 is sleeved with a first connecting ring 6, the spring rod 2 is installed on the top of the disc spring support and hanger body 1 and is located inside the mounting ring 5, the top of the spring rod 2 is fixedly connected with a mounting block 3, a return spring 4 is sleeved between the top of the disc spring support and hanger body 1 and the bottom of the mounting block 3 and located on the rod surface of the spring rod 2, the outside of the mounting block 3 is sleeved with a limiting ring 8, the outside of the mounting block 3 and located directly above the limiting ring 8 is sleeved with a swivel 7, the outside of the swivel 7 and A second connecting ring 9 is sleeved on the top of the limiting ring 8, and a telescopic rubber airbag 10 is sleeved between the top of the first connecting ring 6 and the bottom of the second connecting ring 9. The bottom of one side of the telescopic rubber airbag 10 is connected to an air inlet pipe 11, and the bottom of the other side of the telescopic rubber airbag 10 is connected to an air outlet pipe 12. Since the telescopic rubber airbag 10 is made of rubber, it has elastic deformation ability, so that the second connecting ring 9 can rotate without restriction. One end of the reset spring 4 is fixedly connected to the top of the disc spring support and hanger body 1, and the other end of the reset spring 4 is fixedly connected to the bottom of the mounting block 3. The mounting ring 5 is threadedly connected to the first connecting ring 6, and the bottom of the first connecting ring 6 is in contact with the top of the disc spring support and hanger body 1.

[0024] See also Figure 3-4The limiting ring 8 is fixedly connected to the mounting block 3, and the swivel 7 is rotatably connected to the mounting block 3. The second connecting ring 9 can be limited by the limiting ring 8 to improve the threaded connection stability of the second connecting ring 9 and the swivel 7. The outer diameter of the limiting ring 8 is smaller than the inner diameter of the first connecting ring 6, so that the first connecting ring 6 is sleeved from top to bottom to the outside of the mounting ring 5, and the thread of the outer ring surface of the swivel 7 is only located at the bottom of the outer ring surface, ensuring the threaded connection with the second connecting ring 9 and does not affect the disassembly operation of the second connecting ring 9. The swivel 7 is rotatably connected to the mounting block 3, so that after the installation of the telescopic rubber airbag 10 is completed, the two ends of the telescopic rubber airbag 10 can be automatically adjusted to align up and down. The swivel 7 is threadedly connected to the second connecting ring 9, and the bottom of the second connecting ring 9 contacts the top of the limiting ring 8. The end of the inlet pipe 11 away from the telescopic rubber airbag 10 is installed in a downward tilted shape, and a one-way valve is installed on the inlet pipe 11. The end of the outlet pipe 12 away from the telescopic rubber airbag 10 is installed in a downward tilted shape. The one-way valve is installed on the air outlet pipe 12. When the mounting block 3 moves downward, the spring rod 2 can be driven to move downward. The mounting block 3 drives the top of the telescopic rubber airbag 10 to move downward through the second connecting ring 9, so that the telescopic rubber airbag 10 can be squeezed, so that the air inside the telescopic rubber airbag 10 can be discharged through the one-way valve on the air outlet pipe 12. When the mounting block 3 is not squeezed, the return spring 4 can push the mounting block 3 to move upward and reset, and assist the telescopic rubber airbag 10 to restore its deformation. The resilience of the telescopic rubber airbag 10 itself can assist the shape restoration of the telescopic rubber airbag 10. During the restoration process of the telescopic rubber airbag 10, negative pressure can be used to absorb external air from the one-way valve on the air inlet pipe 11 to ensure that the telescopic rubber airbag 10 can be used normally with the extension and contraction of the spring rod 2 inside the disc spring support and hanger body 1. The telescopic rubber airbag 10 can cover the connection between the spring rod 2 and the disc spring support and hanger body 1, effectively improving the anti-corrosion effect inside the disc spring support and hanger body 1.

[0025] Specific implementation method: During the telescopic work of the spring rod 2 at the top of the disc spring support and hanger body 1, the mounting block 3 can be driven to move up and down. The mounting block 3 drives the top of the telescopic rubber airbag 10 to move downward through the second connecting ring 9, and squeezes the return spring 4, so that the telescopic rubber airbag 10 can be squeezed, and then the air inside the telescopic rubber airbag 10 can be discharged through the one-way valve on the outlet pipe 12. When the mounting block 3 is not squeezed, the return spring 4 can push the mounting block 3 to move upward and reset, and assist the telescopic rubber airbag 10 to restore its deformation. The resilience of the telescopic rubber airbag 10 itself can assist the telescopic rubber airbag 10 in restoring its shape. During the recovery process of the telescopic rubber airbag 10, the negative pressure can be used to absorb external air from the one-way valve on the intake pipe 11 to ensure the telescopic The retractable rubber airbag 10 can be used normally as the spring rod 2 inside the disc spring support and hanger body 1 is extended and retracted. The retractable rubber airbag 10 can cover the connection between the spring rod 2 and the disc spring support and hanger body 1, effectively improving the anti-corrosion effect inside the disc spring support and hanger body 1. When the anti-corrosion structure needs to be replaced, the swivel 7 can be held and the second connecting ring 9 can be rotated in the opposite direction. The second connecting ring 9 can move upward while rotating to disconnect the connection with the swivel 7, and then the first connecting ring 6 can be rotated in the opposite direction, so that the first connecting ring 6 can be removed from the outside of the mounting ring 5, and then the retractable rubber airbag 10 can be removed from the outside of the spring rod 2 as a whole from bottom to top, and then the anti-corrosion structure can be replaced, which effectively improves the convenience of replacing the anti-corrosion structure and extends the life of the anti-corrosion protection effect of the disc spring support and hanger.
