Description

Technical Field

[0001] This utility model relates to the field of GIL gas-insulated metal-enclosed transmission line technology, and in particular to a GIL sliding support device. Background Technology

[0002] GIL is a gas-insulated metal-enclosed transmission line, a long-distance power transmission device that uses gas insulation. During installation, it requires a sliding support device. During the installation process, the GIL needs to be moved, and friction will occur between the GIL and the sliding support device during the movement. Chinese Patent Publication No. CN218124141U discloses a GIL sliding support device, including a mounting plate and a sliding support device. The sliding support device includes an arc-shaped plate, a connecting plate, a connecting rod, a mounting groove, balls, a locking block, a bearing, and mounting holes. The arc-shaped plate is symmetrically mounted on the top of the mounting plate. Each arc-shaped plate has three mounting grooves on its outer wall, and balls are installed inside each mounting groove. The top of the mounting plate has symmetrically opened limit holes and two sets of second threaded holes. In this existing design, although the installation groove and ball bearings effectively solve the problem of friction between the GIL and the sliding support during installation, which can lead to damage, the ball bearings installed inside the installation groove effectively reduce friction and wear during movement, thus extending the lifespan of the GIL. The connecting rod, second threaded hole, and bearings effectively solve the problem of inconvenient disassembly and maintenance after installation of traditional sliding support devices. The threaded connection of the connecting rod to the second threaded hole facilitates the fixing of the sliding device and makes disassembly easier. However, the existing device relies on the threaded connection to directly fix it to the mounting surface. Each installation and disassembly requires fixing multiple bolts one by one, which is a cumbersome process, increases maintenance time and labor costs, and has high requirements for the flatness of the mounting surface. If the mounting surface is slightly uneven or the material hardness is uneven, it can easily lead to loose fixing or local stress, affecting the fixing effect of the device. Therefore, a GIL sliding support device is designed to solve the above problems. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides a GIL sliding support device, which features quick installation and disassembly.

[0004] The present invention adopts the following technical solution: a GIL sliding support device, including a mounting plate, a support plate fixedly mounted on the surface of the mounting plate, an arc-shaped plate fixedly mounted on the top surface of the support plate, a fixing component mounted on the surface of the mounting plate, the fixing component including a threaded rod and a suction cup, the threaded rod being rotatably connected to the surface of the mounting plate, the suction cup being fixedly mounted on the back of the mounting plate, a piston cavity being opened on one side of the suction cup, a piston rod being inserted inside the piston cavity, a piston head being fixedly mounted on one end of the piston rod, and a threaded groove being opened on the other end of the piston rod.

[0005] As a preferred embodiment of the GIL sliding support device of this utility model, a rotating block is fixedly installed at one end of the threaded rod.

[0006] In a preferred embodiment of the GIL sliding support device of this utility model, the edge of the piston head and the inner wall of the piston cavity are in close contact.

[0008] As a preferred embodiment of the GIL sliding support device of this utility model, a groove is provided on the back of the mounting plate, and the piston rod is slidably connected to the inside of the groove.

[0009] In a preferred embodiment of the GIL sliding support device of this utility model, the threaded rod is inserted into the inside of the threaded groove, and the threads on the surface of the threaded rod and the threads inside the threaded groove are engaged.

[0010] As a preferred embodiment of the GIL sliding support device of this utility model, the number of fixing components is four sets, and the four sets of fixing components are respectively installed at the four corners of the back of the mounting plate.

[0011] In a preferred embodiment of the GIL sliding support device of this utility model, the mounting plate and the support plate are vertically distributed, a support rod is fixedly installed between the mounting plate and the support plate, and a reinforcing rib is fixedly installed between the support rod and the mounting plate.

[0012] As a preferred embodiment of the GIL sliding support device of this utility model, the reinforcing rib is made of aluminum alloy.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: through the threaded rod and the suction cup with the piston cavity, when the threaded rod rotates, it can drive the piston rod to move in the piston cavity, so that a negative pressure is formed inside the suction cup, thereby generating an adsorption force. The suction cup is firmly adsorbed by utilizing the air pressure difference, without the need for drilling or complex pretreatment on the mounting surface. Furthermore, the four sets of fixing components are distributed at the four corners of the mounting surface, forming a uniformly distributed adsorption force, which effectively enhances the overall vibration resistance and anti-displacement capability. The exhaust channel can smoothly expel air during the adsorption process, avoiding the air cushion effect from affecting the adsorption effect. The slide can guide the piston rod to move along the set path, avoiding deflection or jamming, and ensuring smooth movement. The support rod and reinforcing ribs further strengthen the structural rigidity, so that the device maintains its shape stability when under load. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1 In existing technology, the existing GIL sliding support device includes a mounting plate and a sliding support device. The sliding support device includes an arc-shaped plate, a connecting plate, a connecting rod, mounting grooves, ball bearings, a locking block, bearings, and mounting holes. The arc-shaped plate is symmetrically mounted on the top of the mounting plate. Each arc-shaped plate has three mounting grooves on its outer wall, and ball bearings are installed inside each mounting groove. Limit holes are symmetrically opened on the top of the mounting plate, and two sets of second threaded holes are also symmetrically opened on the top of the mounting plate. This GIL sliding support device effectively solves the problem of GIL installation issues during the use of traditional sliding support devices by setting up mounting grooves and ball bearings. When the glider needs to be moved, friction will occur between it and the sliding support device during the movement, which can lead to damage to the glider. The ball bearings are installed inside the mounting groove, which effectively reduces the friction between the glider and the sliding device during the movement, thus reducing the wear of the glider and extending its service life. The design of the connecting rod, the second threaded hole, and the bearing effectively solves the problem of the inconvenience of disassembly, replacement, and maintenance of the traditional sliding support device after installation. The connecting rod is threaded to the second threaded hole, which facilitates the fixing of the sliding device and also makes disassembly more convenient.

[0019] This application incorporates the aforementioned prior art, such as Figures 1 to 4 As shown, this utility model provides a technical solution: a GIL sliding support device, including a mounting plate 1, a support plate 2 fixedly mounted on the surface of the mounting plate 1, an arc-shaped plate 3 fixedly mounted on the top surface of the support plate 2, a fixing component 4 mounted on the surface of the mounting plate 1, the fixing component 4 including a threaded rod 401 and a suction cup 402, the threaded rod 401 being rotatably connected to the surface of the mounting plate 1, the suction cup 402 being fixedly mounted on the back of the mounting plate 1, a piston cavity 404 being opened on one side of the suction cup 402, a piston rod 406 being inserted into the piston cavity 404, a piston head 407 being fixedly mounted on one end of the piston rod 406, and a threaded groove 408 being opened on the other end of the piston rod 406.

[0020] In this implementation scheme: the threaded rod 401 and the suction cup 402 with piston cavity 404 are connected. When the threaded rod 401 rotates, it can drive the piston rod 406 to move in the piston cavity 404, so that negative pressure is formed inside the suction cup 402, thereby generating suction force. The suction cup 402 is firmly adsorbed by the air pressure difference, without the need for drilling or complex pretreatment on the mounting surface. Furthermore, the four sets of fixing components 4 are distributed at the four corners of the mounting surface to form a uniformly distributed suction force, which effectively enhances the overall anti-vibration and anti-displacement ability. The exhaust channel 409 can smoothly expel air during the adsorption process, avoiding the air cushion effect from affecting the adsorption effect. The slide groove 405 can guide the piston rod 406 to move along the set path, avoiding deflection or jamming, and ensuring smooth movement.

[0021] Combining the above solutions: Furthermore: like Figures 1 to 3 As shown; In an optional embodiment, to facilitate the rotation of the threaded rod 401, a rotating block 403 is fixedly mounted on one end of the threaded rod 401.

[0022] In this embodiment, a rotating block 403 is fixedly installed at one end of the threaded rod 401. By rotating the rotating block 403, the threaded rod 401 can be driven to rotate, thereby causing the piston rod 406 to move.

[0023] Combining the above solutions: Furthermore: like Figures 3 to 4 As shown; In order to create a negative pressure inside the suction cup 402, in an optional embodiment, the edge of the piston head 407 is in close contact with the inner wall of the piston chamber 404.

[0024] In this embodiment: the edge of the piston head 407 is in close contact with the inner wall of the piston cavity 404. When the threaded rod 401 rotates, it can drive the piston rod 406 to move in the piston cavity 404, so that a negative pressure is formed inside the suction cup 402, thereby generating an adsorption force, and the suction cup 402 is firmly adsorbed by utilizing the air pressure difference.

[0025] Combining the above solutions: Furthermore: like Figures 3 to 4 As shown; In order to avoid the air cushion effect from affecting the adsorption effect, in an optional embodiment, an exhaust channel 409 is provided between the suction cup 402 and the mounting plate 1.

[0026] In this embodiment, an exhaust channel 409 is provided between the suction cup 402 and the mounting plate 1, which allows the air in the piston chamber 404 to be smoothly discharged during the adsorption process, so that a negative pressure is formed inside the suction cup 402, thereby generating an adsorption force.

[0027] Combining the above solutions: Furthermore: like Figures 3 to 4 As shown; To improve the movement stability of the piston rod 406, in an optional embodiment, a groove 405 is provided on the back of the mounting plate 1, and the piston rod 406 is slidably connected to the inside of the groove 405.

[0028] In this embodiment: a groove 405 is provided on the back of the mounting plate 1, and the piston rod 406 is slidably connected to the inside of the groove 405. When the threaded rod 401 is rotated, the threaded rod 401 can drive the piston rod 406 to move, and the piston rod 406 can then slide in the groove 405, thereby improving the movement stability of the piston rod 406.

[0029] Combining the above solutions: Furthermore: like Figures 3 to 4 As shown; In order to make the threaded rod 401 rotate and drive the piston rod 406 to move, in an optional embodiment, the threaded rod 401 is inserted into the inside of the threaded groove 408, and the threads on the surface of the threaded rod 401 and the threads inside the threaded groove 408 are engaged.

[0030] In this embodiment, the threaded rod 401 is inserted into the threaded groove 408. When the threaded rod 401 rotates, the threads on the surface of the threaded rod 401 and the threads inside the threaded groove 408 mesh with each other. Therefore, the threaded rod 401 can drive the piston rod 406 to slide inside the slide groove 405, thereby creating a negative pressure inside the suction cup 402.

[0031] Combining the above solutions: Furthermore: like Figures 1 to 2 As shown; To improve the fixing effect of the mounting plate 1, in an optional embodiment, there are four sets of fixing components 4, which are respectively installed at the four corners of the back of the mounting plate 1.

[0032] In this embodiment, there are four sets of fixing components 4. The four sets of fixing components 4 are installed at the four corners of the back of the mounting plate 1. The four sets of fixing components 4 are distributed at the four corners of the mounting surface to form a uniformly distributed adsorption force, which effectively enhances the overall vibration resistance and offset resistance.

[0033] Combining the above solutions: Furthermore: like Figures 1 to 2 As shown; To improve the fixing effect of the support plate 2, in an optional embodiment, the mounting plate 1 and the support plate 2 are vertically distributed, a support rod 5 is fixedly installed between the mounting plate 1 and the support plate 2, and a reinforcing rib 6 is fixedly installed between the support rod 5 and the mounting plate 1.

[0034] In this embodiment: the mounting plate 1 and the support plate 2 are vertically distributed, a support rod 5 is fixedly installed between the mounting plate 1 and the support plate 2, and a reinforcing rib 6 is fixedly installed between the support rod 5 and the mounting plate 1, so that the device maintains a stable shape when bearing load.

[0035] Combining the above solutions: Furthermore: like Figures 1 to 2 As shown; To improve the strength of the support rod 5, in an optional embodiment, the reinforcing rib 6 is made of aluminum alloy.

[0036] In this embodiment, the reinforcing rib 6 is made of aluminum alloy. Aluminum alloy is lightweight, has high strength and good wear resistance, which can improve the supporting strength of the reinforcing rib 6 and extend its service life.

[0037] Working principle: During installation, the suction cup 402 on the back of the mounting plate 1 is attached to the preset mounting surface. Then, the threaded rod 401 is rotated, and the threaded groove 408 at the end of the threaded rod 401 meshes with it, converting the rotational motion into the linear motion of the piston rod 406. The piston rod 406 slides in the sliding groove 405 on the back of the mounting plate 1. The linear motion of the piston rod 406 pushes the piston head 407 at one end to move in the piston cavity 404 of the suction cup 402. Since the edge of the piston head 407 is tightly attached to the inner wall of the piston cavity 404, an effective seal can be formed. When the piston head 407 moves into the suction cup 402, it will displace and reduce the air volume in the piston cavity 404. The displaced air passes through the opening in the suction cup 402. The exhaust channel 409 between the disc 402 and the mounting plate 1 is directed to the outside, creating a partial vacuum inside the piston chamber 404. This generates a negative pressure state lower than the atmospheric pressure of the external environment. The pressure difference between the inside and outside acts on the suction cup 402, causing it to be firmly adsorbed onto the mounting surface, thus achieving the initial fixation of the device. When it is necessary to remove the mounting plate 1, the threaded rod 401 is rotated in the opposite direction, driving the piston rod 406 and piston head 407 to return to their original positions away from the inside of the suction cup 402. The return movement of the piston head 407 releases the sealing state of the piston chamber 404, and external air can re-enter the cavity through the exhaust channel 409 and other paths, quickly eliminating the pressure difference between the inside and outside. The adsorption force then disappears, and the mounting plate 1 can be easily removed from the mounting surface.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
