Description

Technical Field

[0001] This utility model relates to the field of mine switchboard technology, specifically to a pneumatic switchboard device. Background Technology

[0002] The mine pneumatic automatic switch device refers to a device used to adjust the switch. Mine pneumatic automatic switch devices are often used in mining areas, and workers often use the drive on the pneumatic switch to adjust them.

[0003] A search revealed CN216833687U, entitled "A Pneumatically Controlled Automatic Track Switch Device for Mining." This application addresses the problem that after prolonged use, the friction between the driver and the pneumatic switch increases, affecting the driver's sliding and reducing its lifespan, thus impacting the switch's adjustment. While a lubrication device can lubricate the driver, reducing wear and extending its lifespan, this application involves injecting lubricating oil into a sponge and then applying it through friction between the driver and the sponge. This requires the sponge to be in contact with the driver for lubrication, which can lead to aging and wear over time, affecting the stability of the application. Furthermore, the driver surface lacks effective protection, and the harsh working conditions in mines pose a risk of collision damage. Further improvements are needed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a pneumatic switch device, which has the following advantages:

[0019] (1) This utility model adopts a nozzle and an outer sleeve. The outer sleeve is fitted on the outside of the driver. The inside of the outer sleeve contains lubricating oil. The level of the lubricating oil is lower than the bottom of the through hole. The bottom of the suction pipe is submerged in the lubricating oil.

When the piston moves, the air pressure inside the delivery cylinder decreases. The suction pipe draws the lubricating oil into the delivery cylinder. When the driver moves inward, the piston moves in the opposite direction, squeezing the lubricating oil into the delivery pipe and spraying it out along the nozzle onto the outer surface of the driver to lubricate the driver, reduce driver wear, and extend the driver's service life. By spraying lubricating oil, the driver surface is lubricated.

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a pneumatic switch device is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the pneumatic switch device according to an embodiment of the present invention includes a pneumatic switch body 1 and a driver 3. The driver 3 is installed at the output end of the pneumatic switch body 1, which is a common structure in the art. An outer sleeve 2 is fixedly sleeved on one side surface of the pneumatic switch body 1 on the outside of the driver 3, and a through hole 5 is opened at the other end of the outer sleeve 2. The driver 3 passes through the outer sleeve 2. A conveying cylinder 6 is fixedly suspended inside the outer sleeve 2 by a lifting ring 13. A piston 7 is slidably connected inside the conveying cylinder 6, and a connecting rod 8 is fixedly installed at one end of the piston 7. A fixing ring 9 is fixedly sleeved on the outer surface of the driver 3, and a moving plate 10 is fixedly installed on the top surface of the fixing ring 9. The moving plate 10 is fixedly connected to the other end of the connecting rod 8. An infusion tube 4 is connected through one end of the conveying cylinder 6, and a nozzle 12 is connected through the surface of the infusion tube 4. A suction tube 11 is connected through one end of the conveying tube below the infusion tube 4, and the suction tube 11 extends around the driver 3 to the bottom of the outer sleeve 2. The drive unit 3 is equipped with a lubricating oil inside, with the oil level below the bottom of the through hole 5. The outer sleeve 2 is fitted onto the outside of the drive unit 3. The outer sleeve 2 is also equipped with lubricating oil inside, with the oil level below the bottom of the through hole 5. The bottom of the suction pipe 11 is submerged in the lubricating oil. When the drive unit 3 moves outward, it moves the fixing ring 9 and the moving plate 10, which in turn moves the connecting rod 8 and pulls the piston 7. When the piston 7 moves, the air pressure inside the delivery cylinder 6 decreases, and the suction pipe 11 draws the lubricating oil into the delivery cylinder 6. When the drive unit 3 moves inward, the piston 7 moves in the opposite direction, squeezing the lubricating oil into the delivery pipe 4 and spraying it out along the nozzle 12 onto the outer surface of the drive unit 3. This lubricates the drive unit 3, reduces wear, and extends its service life. By spraying lubricating oil, the surface of the drive unit 3 is lubricated. The automatic spraying is completed by the movement of the drive unit 3, avoiding contact between the drive unit 3 and the sponge. This avoids the problem of sponge aging and wear affecting the service life, further extending the service life and improving the stability of operation.

[0031] In one embodiment, a first check valve 14 is installed on the surface of the infusion tube 4, and the first check valve 14 is installed in the direction that lubricating oil enters the infusion tube 4, so as to prevent air from entering the delivery cylinder 6 when the piston 7 moves outward.

[0032] In one embodiment, a second one-way valve 15 is installed on the surface of the suction pipe 11, and the second one-way valve 15 is installed in the direction that the lubricating oil enters the inside of the delivery cylinder 6, so as to prevent the lubricating oil from flowing back into the suction pipe 11 when the piston 7 moves.

[0033] In one embodiment, the conveying cylinder 6 is a cylindrical closed structure, and the inner wall of the conveying cylinder 6 is polished to facilitate the movement of the piston 7 and reduce residue.

[0034] In one embodiment, the lifting ring 13 is fixedly connected to the outer surface of the outer sleeve 2, and the top surface of the lifting ring 13 is fixedly connected to the inner top surface of the outer sleeve 2. Multiple lifting rings 13 are arranged to improve the stability of the fixation.

[0035] In one embodiment, the suction tube 11 is a bent tube, and the suction tube 11 is located on one side of the driver 3, so as not to affect the operation of the driver 3.

[0036] In one embodiment, the outer sleeve 2, the driver 3, and the through hole 5 are arranged coaxially, and the diameter of the through hole 5 is larger than the outer diameter of the driver 3 to facilitate the passage of the driver 3.

[0037] In one embodiment, the length of the outer sleeve 2 matches the length of the driver 3, and the outer sleeve 2 is made of stainless steel tube with a wall thickness of not less than 3mm, which has high structural strength. In addition to holding lubricating oil, the outer sleeve 2 also provides external protection for the driver 3, avoiding damage to the driver 3 caused by impacts from debris such as gravel, further extending the service life of the driver 3 and improving the safety of use. At the same time, when replenishing lubricating oil, it is only necessary to use a syringe to inject the lubricating oil into the inner cavity of the outer sleeve 2 through the through hole 5, which is more convenient to use.

[0038] Working principle:

[0039] The outer sleeve 2 is fitted onto the outside of the driver 3. The outer sleeve 2 contains lubricating oil, with the oil level below the bottom of the through hole 5. The bottom of the suction pipe 11 is submerged in the lubricating oil. When the driver 3 moves outward, it moves the fixed ring 9 and the moving plate 10, which in turn moves the connecting rod 8, pulling the piston 7. When the piston 7 moves, the air pressure inside the delivery cylinder 6 decreases, and the suction pipe 11 draws the lubricating oil into the delivery cylinder 6. When the driver 3 moves inward, the piston 7 moves in the opposite direction, squeezing the lubricating oil into the delivery pipe 4, which is then sprayed out along the nozzle 12 onto the outer surface of the driver 3, lubricating the driver 3, reducing wear, and extending its service life. The lubricant is applied to the surface of the actuator 3 by spraying lubricating oil. The spraying is completed automatically by the movement of the actuator 3, avoiding contact between the actuator 3 and the sponge. This avoids the problem of sponge aging and wear affecting service life, further extending service life and improving operational stability. At the same time, the outer sleeve 2 not only holds the lubricating oil but also provides external protection for the actuator 3, preventing damage to the actuator 3 caused by impacts from gravel or other debris. This further extends the service life of the actuator 3 and improves safety. In addition, when replenishing the lubricating oil, it is only necessary to use a syringe to inject the lubricating oil into the inner sleeve 2 through the through hole 5, making it more convenient to use.
