Description

Technical Field

[0001] This utility model relates to the field of ultra-high voltage switch housing processing technology, specifically to an ultra-high voltage switch housing flipping device. Background Technology

[0002] Ultra-high voltage switches are frequently used in large-scale power transmission equipment. The structures of ultra-high voltage switch housings vary; some use a large-diameter cylindrical tube as the housing, with other branch pipes welded to the outer wall for easy overall switch installation. During manufacturing, drilling, grinding, and welding are required on the housing, necessitating its rotation to allow for machining in different positions. Currently, the rotation of the housing is primarily done manually, and after the position is determined, it is fixed using pipe clamps. This rotation process is time-consuming, labor-intensive, inefficient, and poses low operational safety risks. Furthermore, the stability after fixing is poor, easily leading to machining errors and overall inconvenience in use. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an ultra-high voltage switch housing flipping device, which solves the problems of inconvenient operation, low efficiency, and poor stability of ultra-high voltage switch housing flipping.

[0004] This utility model is achieved through the following technical solution: an ultra-high voltage switch housing flipping device, comprising a workbench, on which a first flipping mechanism and a second flipping mechanism are symmetrically arranged left and right. Each of the first and second flipping mechanisms includes a bracket, a rotating shaft rotatably connected to the bracket, a support base fixed to one end of the rotating shaft, and a bidirectional telescopic cylinder fixed to the support base. Each of the two telescopic rods of the bidirectional telescopic cylinder has a top block fixedly attached. A motor for driving the rotating shaft to rotate is fixedly mounted on the bracket. The first flipping mechanism is fixedly mounted on the workbench, and the second flipping mechanism slides on the workbench. A first driving mechanism for driving the second flipping mechanism to slide in the left and right direction is provided on the workbench.

[0005] This design uses a first drive mechanism to drive the second tilting mechanism to slide left and right, allowing for convenient adjustment of the distance between the first and second tilting mechanisms to accommodate shells of varying lengths. This enables the bidirectional telescopic cylinders of both mechanisms to be inserted into the openings at both ends of the shell. The synchronous extension of the two telescopic rods of the bidirectional telescopic cylinders causes the top blocks at both ends to press against the inner walls of the shell, thus securing the ends of the shell. Furthermore, a motor drives the rotating shafts of both mechanisms to rotate synchronously in the same direction, causing the support base to rotate and ultimately tilting the shell. This design is convenient, time-saving, labor-saving, and improves processing efficiency.

[0006] As an optimization, at least one support assembly is slidably connected to the worktable. The support assembly is located between the first and second tilting mechanisms and slides in the left-right direction. The support assembly includes a first slider that slides onto the worktable. A first one-way telescopic cylinder is fixedly connected to the bottom of the first slider. The telescopic rod of the first one-way telescopic cylinder passes through the first slider and is fixedly connected to a support plate. Two support rollers are mounted on the top of the support plate, arranged in a front-to-back pattern. This optimization uses the support assembly to support the bottom of the housing. The sliding of the support assembly allows for convenient support at different positions of the housing. The first one-way telescopic cylinder can drive the lifting and lowering of the support plate, thereby adjusting the height of the support rollers according to the housing diameter, enabling the support rollers to support housings of different diameters and heights, improving the stability of the housing during tilting.

[0007] As an optimization, the worktable is provided with a sliding groove extending in the left-right direction. The first slider slides in cooperation with the sliding groove, and a second slider is fixedly connected to the bottom of the support of the second flipping mechanism, which also slides in cooperation with the sliding groove. This optimized support assembly and the second flipping mechanism both slide left and right along the sliding groove, ensuring stability during sliding.

[0008] As an optimization, the first driving mechanism is a second one-way telescopic cylinder. The second one-way telescopic cylinder is located on the side of the second tilting mechanism away from the first tilting mechanism and is fixedly connected to the worktable. The telescopic rod of the second one-way telescopic cylinder is connected to the second slider. This optimization drives the left and right sliding of the second tilting mechanism through the extension and retraction of the second one-way telescopic cylinder.

[0009] As an optimization, a buffer assembly is provided on the side of the second tilting mechanism away from the first tilting mechanism. The buffer assembly includes a vertical plate fixed to the worktable, and a push rod extending in a left-right direction passes through the vertical plate. A limit block is fixed to the end of the push rod near the second tilting mechanism. The limit block is located on the sliding path of the second tilting mechanism, and a spring is provided between the limit block and the vertical plate. This optimization improves stability by buffering and limiting the second tilting mechanism when it moves away from the first tilting mechanism.

[0010] As an optimization, the top block includes a fixed plate and a semi-circular rubber pad. The fixed plate is fixedly connected to the telescopic rod of the bidirectional telescopic cylinder, and the rubber pad is fixedly connected to the side of the fixed plate away from the bidirectional telescopic rod. This optimized top block contacts the housing through the rubber pad, resulting in stronger friction when it presses against the housing, thus providing a more stable fixation and enabling the housing to rotate.

[0011] As an optimization, multiple notches are formed on the outer wall of the rubber pad along the arc direction. This optimization, by creating notches on the rubber pad, provides deformation space when tightened against the housing, improving durability. Furthermore, when the rubber pad contacts the housing, multiple contact surfaces are formed, and the force is more concentrated on each contact surface, thereby improving the tightening and fixing effect on the housing.

[0012] The beneficial effects of this utility model are as follows: The first driving mechanism drives the second flipping mechanism to slide left and right, allowing for convenient adjustment of the distance between the first and second flipping mechanisms according to different shell lengths. This enables the bidirectional telescopic cylinders of the first and second flipping mechanisms to be inserted into the openings at both ends of the shell. The two telescopic rods of the bidirectional telescopic cylinders extend synchronously, causing the top blocks at both ends to press against the inner walls of the shell, achieving a tightening and fixing of the shell ends. The support assembly supports the bottom of the shell, and its sliding motion allows for convenient support at different positions. The first unidirectional telescopic cylinder drives the support plate to rise and fall, allowing for adjustment of the support roller height according to different shell diameters, thus improving the stability of the shell during flipping. Furthermore, the motor drives the rotating shafts of the first and second flipping mechanisms to rotate synchronously in the same direction, causing the support base to rotate and consequently the shell to flip. This design is convenient, time-saving, labor-saving, and improves processing efficiency. Attached Figure Description

[0026] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0027] like Figures 1-7 As shown, an ultra-high voltage switch housing flipping device includes a workbench 1. A first flipping mechanism 2 and a second flipping mechanism 3 are symmetrically arranged on the workbench 1, and the first flipping mechanism 2 and the second flipping mechanism 3 have identical structures. Both the first flipping mechanism 2 and the second flipping mechanism 3 include a bracket 21, a rotating shaft 22 rotatably connected to the bracket 21, a support seat 23 fixed to one end of the rotating shaft 22, and a bidirectional telescopic cylinder 24 fixed to the support seat 23. Each of the two telescopic rods of the bidirectional telescopic cylinder 24 has a top block 25 fixedly attached. A motor 26 for driving the rotating shaft 22 is fixedly mounted on the bracket 21. The first flipping mechanism 2 is fixedly mounted on the workbench 1, and the second flipping mechanism 3 is slidably mounted on the workbench 1. A first driving mechanism for driving the second flipping mechanism 3 to slide in the left-right direction is provided on the workbench 1.

[0028] Specifically, the bracket 21 is perpendicular to the worktable 1. The bracket 21 of the first flipping mechanism 2 is fixedly connected to the worktable 1, and the bracket 21 of the second flipping mechanism 3 is slidably connected to the worktable 1. The rotating shaft 22 is horizontally arranged and rotatably connected to the bracket 21. The support base 23 of the first flipping mechanism 2 and the support base 23 of the second flipping mechanism 3 are arranged opposite to each other. The support base 23 has a C-shaped structure. The bidirectional telescopic cylinder 24 is perpendicular to the rotating shaft 22. The bidirectional telescopic cylinder 24 is fixedly installed in the opening of the C-shaped support base 23. The two telescopic rods of the bidirectional telescopic cylinder 24 pass through the two opposite side walls of the C-shaped support base 23 and are fixedly connected to the top block 25. In this way, the stability of the telescopic rods of the bidirectional telescopic cylinder during extension and retraction can be improved by the guiding support of the two opposite side walls of the C-shaped support base 23.

[0029] Specifically, the top block 25 includes a fixed plate 251 and a semi-circular rubber pad 252. The fixed plate 251 is fixedly connected to the telescopic rod of the bidirectional telescopic cylinder 24, and the rubber pad 252 is fixedly connected to the side of the fixed plate 251 away from the bidirectional telescopic cylinder 24. Through the contact between the rubber pad 252 and the housing 8, the friction is stronger when it presses against the housing, resulting in a more stable fixation of the housing and better enabling the housing to rotate.

[0030] Preferably, the outer wall of the rubber pad 252 has multiple notches 253 along the arc direction. By creating multiple notches 253 on the rubber pad 252, multiple contact surfaces are formed when the rubber pad 252 contacts the housing 8, and the force on each contact surface is more concentrated, thereby improving the tightening and fixing effect on the housing. In addition, the notches allow for deformation space on the contact surfaces, improving durability.

[0031] Specifically, the workbench 1 has a sliding groove 11 extending in the left-right direction. The bottom of the bracket 21 of the second flipping mechanism 3 is fixedly connected to a second slider 7, which slides in cooperation with the sliding groove 11. In this embodiment, the sliding groove 11 has protruding limiting protrusions 12 on its front and rear opposite sidewalls, which extend along the length of the sliding groove 11. The second slider 7 has grooves on its front and rear sidewalls that fit with the limiting protrusions 12. The second slider 7 engages with the limiting protrusions 12 through the grooves and slides along the limiting protrusions 12, thus achieving a sliding cooperation with the sliding groove 11 and ensuring the stability of the second flipping mechanism 3 when sliding left and right.

[0032] Specifically, the first driving mechanism is a second one-way telescopic cylinder 6. The second one-way telescopic cylinder 6 is located on the side of the second flipping mechanism 3 away from the first flipping mechanism 2 and is fixedly connected to the worktable 1. The telescopic rod of the second one-way telescopic cylinder 6 is connected to the second slider 7. In this embodiment, the telescopic rod of the second one-way telescopic cylinder 6 passes through the worktable 1 and is fixedly connected to the second slider 7. The extension and retraction of the second one-way telescopic cylinder 6 drives the left and right sliding of the second flipping mechanism 3.

[0033] Preferably, a buffer assembly 5 is provided on the side of the second flipping mechanism 3 away from the first flipping mechanism 2. The buffer assembly 5 includes a vertical plate 51 fixedly connected to the worktable 1. A top rod 53 extending in a left-right direction is passed through the vertical plate 51. A limit block 52 is fixedly connected to one end of the top rod 53 near the second flipping mechanism 3. The limit block 52 is located on the sliding path of the second flipping mechanism 3. A spring 54 is provided between the limit block 52 and the vertical plate 51. In this embodiment, a stop block 55 is fixedly connected to the end of the top rod 53 away from the limit block 52. The stop block 55 and the limit block 52 are located on the left and right sides of the vertical plate 51, respectively, to prevent the top rod from detaching from the vertical plate. The spring 54 is sleeved on the top rod 53, and the limit block 52 contacts the bracket 21 of the second flipping mechanism 3. When the second flipping mechanism 3 slides away from the first flipping mechanism 2, the buffer assembly 5 provides buffering and limiting, improving stability.

[0034] At least one support component 4 is slidably connected to the workbench 1. The support component 4 is located between the first flipping mechanism 2 and the second flipping mechanism 3 and slides in the left and right direction. In this embodiment, two support components 4 are provided between the first flipping mechanism 2 and the second flipping mechanism 3.

[0035] Specifically, the support assembly 4 includes a first slider 41 that slides against the worktable 1, and the first slider 41 is slidably engaged with the slide groove 11. The front and rear sidewalls of the first slider 41 are also provided with grooves that fit into the limiting protrusion 12. The first slider 41 is also engaged with the limiting protrusion 12 through the grooves and slides along the limiting protrusion 12, achieving a sliding engagement with the slide groove 11 and ensuring the stability of the support assembly 4 when sliding left and right.

[0036] A first one-way telescopic cylinder 42 is fixedly connected to the bottom of the first slider 41. The telescopic rod of the first one-way telescopic cylinder 42 passes through the first slider 41 and is fixedly connected to a support plate 43. The support plate 43 is located above the first slider 41, and two support rollers 44 are installed on the top of the support plate 43, arranged in a front-to-back pattern. The first one-way telescopic cylinder 42 can drive the support plate 43 to rise and fall, thereby adjusting the height of the support rollers 44 according to the height of the housing. The two support rollers 44 support the housing 8, improving the stability when the housing is flipped. The bottom of the housing 8 is supported by two support components 4, further improving stability. The sliding arrangement of the support components 4 allows for easy adjustment of the spacing to support different positions of the housing 8.

[0037] Working principle: In use, the housing 8 is placed on two support components 4, with two support rollers 44 supporting the lower part of the housing 8. The height of the housing 8 is adjusted by the extension and retraction of the first one-way telescopic cylinder 42, which drives the support rollers 44 to rise and fall, so that both ends of the housing 8 are coaxially opposite to the first flipping mechanism 2 and the second flipping mechanism 3, respectively. By sliding the support components 4, the housing 8 is moved to the left, so that the support seat 23 of the first flipping mechanism 2 is inserted into one end of the housing 8. Then, the second one-way telescopic cylinder 6 drives the second flipping mechanism 3 to slide, so that the support seat 23 of the second flipping mechanism 3 is inserted into the other end of the housing 8. Finally, the two telescopic rods of the bidirectional telescopic cylinder 24 extend synchronously, so that the two top plates 25 press against the inner wall of the housing 8. The rotating shaft 22 is driven by the motor 26 to rotate, which drives the housing 8 to flip.
