Description

Technical Field

[0001] The utility model relates to the technical field of accumulators, in particular to an anti-wear accumulator. Background Art

[0002] The accumulator is an energy storage device in the hydraulic and pneumatic system. It converts the energy in the system into compression energy or potential energy and stores it at the right time. When the system needs it, it converts the compression energy or potential energy into hydraulic or air pressure energy and releases it to replenish the system. When the system pressure increases instantly, it can absorb this part of the energy to ensure the normal pressure of the entire system.

[0003] When the existing accumulator is put into use after installation, because there is a rigid contact between the accumulator and the mounting frame, and the accumulator will generate vibration when working, so the accumulator and the mounting frame will be worn under the rigid contact. The existing anti-wear device clamps the accumulator and cooperates with the damping spring pad at the bottom of the accumulator to reduce the wear on the accumulator. However, this method has certain limitations because the clamping assembly is in direct contact with the accumulator. During the operation of the accumulator, the clamping assembly will also be vibrated to cause damage to the accumulator. In order to solve this problem, we propose an anti-wear accumulator.

[0023] 1. The wear-resistant accumulator has an airbag and a rubber pad arranged on the clamp arm. The airbag is inflated to ensure that the clamping part of the clamp arm on the accumulator has deformation space. The rubber pad is used to prevent the clamp arm from directly contacting the accumulator body, and prevent the accumulator from being worn due to vibration and friction of the clamp arm during the operation of the accumulator. At the same time, the airbag can fill the gap of the rubber pad to provide support for the clamp arm and improve the stability of the clamping work.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0036] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] When the existing device is in use, the staff puts the accumulator body into the support plate inside the fixing frame, and then uses bolts to control the clamping arm to fix the accumulator.

[0038] In the related art, since there is a rigid contact between the accumulator and the mounting frame, and the accumulator will generate vibration when working, wear will occur between the accumulator and the mounting frame under the rigid contact. The existing anti-wear device reduces the wear on the accumulator by clamping the accumulator and cooperating with the damping spring pad at the bottom of the accumulator. However, in this way, the clamping assembly is in direct contact with the accumulator. During the operation of the accumulator, the clamping assembly will also be vibrated to cause damage to the accumulator, which has certain limitations.

[0039] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an anti-wear accumulator. When it is needed, the accumulator body 13 only needs to be placed on the support plate 251 inside the fixing frame 11, and then the handle 212 is controlled to rotate to make the screw 211 rotate to control the shell 22 to drive the clamping arm 23 to clamp the accumulator body 13. The user then uses an external air pump to inflate the airbag 24 from the inflation port 241 to make the airbag 24 bulge and contact the outer wall of the accumulator body 13. The airbag 24 and the rubber pad 242 avoid direct contact between the clamping arm 23 and the accumulator body 13, thereby preventing the accumulator body 13 from being damaged during operation. When the accumulator body 13 is in operation, the vibration generated by itself conflicts with the clamping force of the clamp arm 23, causing the outer wall of the accumulator body 13 to be worn. At the same time, when the accumulator body 13 is working, the slider 231 arranged on the clamp arm 23 slides up and down in a small range on the slide groove 221 arranged on the shell 22 for controlling the clamp arm 23. At the same time, a damping spring pad 232 is arranged inside the slide groove 221. Therefore, when the accumulator body 13 is working, the clamp arm 23 can move up and down in a small range on the shell 22, thereby further avoiding the conflict between the vibration force of the accumulator body 13 and the clamping force of the clamp arm 23, and further reducing the wear caused by vibration between the clamp arm and the accumulator body.

[0040] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0041] Combination Figure 1-Figure 4The embodiment of the present application provides an anti-wear accumulator, including an accumulator device 1; the accumulator device 1 includes: a footrest 12 is arranged at the bottom of a fixing frame 11, and an accumulator body 13 is arranged on the fixing frame 11; an anti-wear device 2 is arranged on the accumulator device 1, and the anti-wear device 2 includes: a frame 21 is symmetrically arranged on the fixing frame 11, a screw 211 is threadedly arranged on the frame 21, and a handle 212 is arranged on the screw 211; a shell 22 is rotatably arranged on the screw 211 through a bearing 213, and a slide groove 221 is arranged on the shell 22; a clamp arm 23 is slidably connected to the slide groove 221 through a slider 231, and a damping spring pad 232 is arranged inside the slide groove 221, and the slider 231 and the damping spring pad 232 are fixedly connected; an airbag 24 is arranged on the clamp arm 23, and an inflation port 241 is penetrated through the clamp arm 23.

[0042] When it is needed, the accumulator body 13 only needs to be placed on the support plate 251 inside the fixing frame 11, and then the handle 212 is controlled to rotate so that the screw 211 rotates to control the housing 22 to drive the clamping arm 23 to clamp the accumulator body 13. The user then connects an external air pump to inflate the airbag 24 from the air charging port 241, so that the airbag 24 swells and contacts the outer wall of the accumulator body 13. The airbag 24 and the rubber pad 242 avoid direct contact between the clamping arm 23 and the accumulator body 13, thereby preventing the accumulator body 13 from vibrating and the clamping force of the clamping arm 23 when working. The collision causes the outer wall of the accumulator body 13 to be worn. At the same time, when the accumulator body 13 is working, the slider 231 arranged on the clamp arm 23 slides up and down in a small range on the slide groove 221 arranged on the shell 22 for controlling the clamp arm 23. At the same time, a damping spring pad 232 is arranged inside the slide groove 221. Therefore, when the accumulator body 13 is working, the clamp arm 23 can move up and down in a small range on the shell 22, thereby further avoiding the conflict between the vibration force of the accumulator body 13 and the clamping force of the clamp arm 23, and further reducing the wear caused by vibration between the clamp arm and the accumulator body.

[0043] In some embodiments, the handle 212 is wheel-shaped, which makes it easier for the user to control the rotation angle of the handle 212 and the force applied to rotate the handle 212.

[0044] In some embodiments, the clamp arm 23 is half-ring-shaped, and the diameter of the clamp arm 23 is not less than the diameter of the accumulator body 13. Because the accumulator body 13 is a can-shaped object, the clamp arm 23 is half-ring-shaped with a diameter larger than the accumulator body 13, and can contain the accumulator body 13 when clamping, so as to facilitate a more secure clamping and fixing of the accumulator body 13.

[0045] In some embodiments, the outer side wall of the clamp arm 23 is provided with a plurality of rubber pads 242, and the rubber pads 242 are distributed on both sides of the airbag 24. The rubber pads 242 have a good friction coefficient, and cooperate with the airbag 24 to avoid direct contact with the accumulator body 13 while also enhancing the clamping of the accumulator body 13.

[0046] In some embodiments, the bulging height of the airbag 24 is the same as the thickness of the rubber pad 242. The bulging height of the airbag 24 and the thickness of the rubber pad 242 are the same to ensure that the airbag 24 can function.

[0047] In some embodiments, a one-way valve is disposed inside the inflation port 241 of the airbag 24. The inflation port 241 is a one-way valve component to ensure that the airbag 24 will not leak after being filled.

[0048] Specifically, the gas is controlled by the air pump to be added into the inflation port 241, and the gas pushes the plug downward, causing the plug to compress the spring. At the same time, the two ends of the top of the plug are slidably connected to the shell through a slide groove, so that the plug moves downward along the slide groove and stops moving when it moves to the bottom of the limit block. At this time, the air inlet and the air outlet are completely opened, and the air enters from the air inlet and is discharged from the air outlet to the inside of the airbag 24, causing the airbag 24 to swell.

[0049] In some embodiments, a plurality of damping spring pads 25 are disposed inside the fixing frame 11, and a support plate 251 is disposed on the damping spring pads 25. The plurality of damping spring pads 25 disposed at the bottom of the support plate 251 can reduce the vibration of the accumulator body 13 when it is working.

[0050] In some embodiments, a gasket 252 is disposed on the support plate 251, and the gasket 252 is made of rubber material. Rubber material has a good friction coefficient and good deformation characteristics, and can protect the bottom of the accumulator body 13.
