Description

Technical Field

[0001] This invention relates to the field of gate valve processing technology, specifically to a rust-proof gate valve and processing equipment. Background Technology

[0002] A gate valve is a valve with a gate as its opening and closing element. The gate moves in a direction perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling. Gate valves achieve sealing through the contact between the valve seat and the gate. Usually, the sealing surface is overlaid with metal material to increase wear resistance. There are rigid gates and resilient gates. Based on the type of gate, gate valves are classified as rigid gate valves and resilient gate valves. The gate valve's opening and closing element is the gate, and the gate moves in a direction perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling.

[0003] However, existing gate valves still have some problems in use: most are manually operated, which is inconvenient. In order to improve the performance of gate valves, anti-rust coatings are sprayed on the surface of the gate valves. However, traditional gate valve anti-rust coating spraying is mostly done manually, which is slow. Therefore, we propose an anti-rust gate valve and processing equipment to solve the above problems.

[0009] As a preferred embodiment of the present invention, the indexing mechanism includes two symmetrically distributed indexing shafts, which are rotatably mounted on both ends of the mounting bracket. An indexing sprocket is fixedly mounted on the bottom of the indexing shaft, and an indexing chain is meshed with the outer sides of the two indexing sprockets. The drive end of the second motor and the top end of one of the indexing shafts are coaxially fixedly mounted.

[0010] As a preferred embodiment of the present invention, the positioning mechanism includes a mounting base, which is fixedly mounted on the outside of the indexing sprocket. A rotating seat is fixedly mounted at the end of the mounting base. A bearing is fixedly mounted on the side of the rotating seat away from the mounting base. A rotating cylinder is fixedly mounted in the middle of the bearing. A positioning disc is fixedly mounted at the bottom end of the rotating cylinder. A positioning outer cylinder is fixedly mounted in the middle of the bottom end of the positioning disc. A plurality of positioning frames arranged in a circular array are slidably mounted at the bottom of the positioning outer cylinder. The opposite ends of the plurality of positioning frames extend into the positioning outer cylinder. A drive disc that cooperates with the positioning frames is rotatably mounted in the positioning outer cylinder. The lower surface of the drive disc contacts the upper surfaces of the plurality of positioning frames. A planar threaded protrusion is integrally formed on the lower surface of the drive disc.

[0011] As a preferred embodiment of the present invention, a second gear is fixedly sleeved on the top outer side of the rotating cylinder, and an external toothed ring frame is fixedly installed on the outer side of the mounting top frame. The second gear and the outer side of the external toothed ring frame in the plurality of positioning mechanisms are meshed and connected.

[0012] As a preferred embodiment of the present invention, a third gear is fixedly sleeved on the top of the second shaft. The ejector assembly includes two electric telescopic rods, which are fixedly installed on one side of the mounting frame. A connecting frame is fixedly installed on the drive end of the electric telescopic rod, and an ejector rack is fixedly installed on the top of the connecting frame. The position of the ejector rack corresponds horizontally to the position of the third gear. The third gear in the plurality of positioning mechanisms can mesh with the ejector rack on the side close to the mounting frame.

[0013] As a preferred embodiment of the present invention, a fixing frame is fixedly installed on the inner side of the arc-shaped rack. The fixing frame is fixedly installed on the side of the mounting top frame near the unloading assembly. The position of the arc-shaped rack and the position of the third gear are horizontally corresponding. The third gear in the plurality of positioning mechanisms can mesh with the side of the arc-shaped rack away from the mounting top frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. By setting up multiple positioning mechanisms and using a rotation mechanism, multiple gate valve outer frames are automatically internally supported and positioned, and multiple gate valve outer frames are driven to rotate. This facilitates the rotary spraying of multi-station anti-rust coating on the gate valve outer frames, improving the efficiency of gate valve outer frame spraying.

[0016] 2. With the material ejection assembly in place, the third gear and the material ejection rack mesh and connect. When the gate valve outer frame continues to drive, the material ejection rack drives the corresponding third gear to rotate in the opposite direction, thereby driving the second shaft to rotate in the opposite direction, which in turn drives the drive disc to rotate in the opposite direction. The planar threaded convex is engaged in the planar threaded groove, synchronously driving multiple positioning frames to slide towards each other. The gate valve outer frame loses its positioning and automatically disengages from the positioning mechanism under its own gravity to automatically eject the material.

[0017] 3. With the help of the arc-shaped rack, when the positioning mechanism after automatic material unloading moves to the feeding station, the outer frame of the gate valve is placed on the outside of the positioning outer cylinder. The positioning mechanism continues to drive the gate valve outer frame. The corresponding third gear and the arc-shaped rack mesh and connect. When the gate valve outer frame continues to drive, the arc-shaped rack drives the corresponding third gear to rotate, drives the second shaft to rotate, and drives the drive disc to rotate. The planar threaded convex is engaged in the planar threaded groove, and the multiple positioning frames are driven to slide in opposite directions to automatically support and position the gate valve outer frame.

[0018] 4. By controlling the start of the first motor to drive the first shaft, the first gear drives the crown gear to rotate, thereby driving the drive tube to rotate and the lifting screw to rotate. This does not affect the lifting screw's sliding up and down in the middle of the drive tube. In conjunction with the internal helical tube, the lifting screw and valve stem are driven to rotate and move up and down, thereby driving the gate to move up and down in the middle of the bottom of the gate valve frame, realizing the automatic opening and closing of the rust-proof gate valve and improving its performance.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: Figure 1-4As shown, the present invention provides a rust-proof gate valve, including a gate valve base frame 1. A gate plate 11 is slidably disposed at the bottom center of the gate valve base frame 1. A sealing gasket 12 that cooperates with the gate plate 11 is fixedly installed on the inner bottom of the gate valve base frame 1. A gate valve top frame 13 is fixedly installed on the top of the gate valve base frame 1 by bolts. A valve stem 14 is movably inserted into the middle of the gate valve top frame 13. The bottom of the valve stem 14 is rotatably engaged with the top of the gate plate 11. A top bracket 15 is fixedly installed on the outer top of the gate valve top frame 13. An internal threaded tube 16 is fixedly installed at the top center of the top of the top bracket 15. A lifting screw 17 is threadedly installed in the middle of the internal threaded tube 16. The lifting screw 17 is fixedly installed on the top of the valve stem 14. By driving the lifting screw 17 to rotate, in cooperation with the internal threaded tube 16, the lifting screw 17 and the valve stem 14 are driven to rotate and move up and down, thereby driving the gate plate 11 to move up and down at the bottom center of the gate valve base frame 1, realizing the opening and closing of the rust-proof gate valve.

[0034] The top end of the inner spiral tube 16 is fixedly installed with a drive outer cylinder 18. The top of the lifting screw 17 moves through the middle of the drive outer cylinder 18. The bottom inner side of the drive outer cylinder 18 is provided with a drive tube 19. The drive tube 19 is movably sleeved on the outside of the lifting screw 17. The inner side of the drive tube 19 has integrally formed symmetrically distributed sliding protrusions 191. The outer side of the lifting screw 17 is provided with a sliding groove 171 that cooperates with the sliding protrusions 191. The sliding protrusions 191 slide and engage in the corresponding sliding grooves 171. By setting the sliding protrusions 191, the sliding protrusions 191 slide and engage in the corresponding sliding grooves 171, controlling the rotation of the drive tube 19, driving the lifting screw 17 to rotate, and not affecting the up and down sliding of the lifting screw 17 in the middle of the drive tube 19.

[0035] A crown gear 111 is fixedly sleeved on the outer bottom of the drive tube 19. The crown gear 111 is rotatably mounted on the inner bottom of the drive outer cylinder 18. A first shaft 112 is rotatably mounted on the side end of the drive outer cylinder 18. One end of the first shaft 112 extends into the drive outer cylinder 18 and is fixedly mounted with a first gear 113. The first gear 113 and the crown gear 111 are meshed together. A first motor 114 is fixedly mounted on the side end of the drive outer cylinder 18. The drive end of the first motor 114 and the end of the first shaft 112 are connected. The valve is coaxially fixed and installed. When in use, the control starts the first motor 114 to drive the first shaft 112 to drive the first gear 113 to drive the crown gear 111 to rotate, thereby driving the drive tube 19 to rotate and the lifting screw 17 to rotate. This does not affect the sliding of the lifting screw 17 up and down in the middle of the drive tube 19. With the help of the inner thread tube 16, the lifting screw 17 and valve stem 14 are driven to rotate and move up and down, thereby driving the gate plate 11 to move up and down in the middle of the bottom of the gate valve base frame 1, realizing the automatic opening and closing of the rust-proof gate valve and improving the use effect.

[0036] A protective tube 115 is fixedly installed at the top center of the drive outer cylinder 18. The top of the lifting screw 17 is movably engaged with the bottom of the protective tube 115. When the lifting screw 17 moves up and down, it moves up and down in the protective tube 115, which protects the lifting screw 17.

[0037] like Figure 5-11 As shown, a processing equipment for rust-proof gate valves includes a top base frame 2. A mounting top frame 3 is fixedly installed at the bottom end of the top base frame 2. A rotation mechanism 4 is provided on the mounting top frame 3. A positioning mechanism 5 is provided on the outer side of the rotation mechanism 4. Multiple positioning mechanisms 5 are evenly distributed. A material ejection assembly 6 is provided on one side of the mounting top frame 3. An arc-shaped rack 7 is provided on the side of the mounting top frame 3 near the material ejection assembly 6. A second motor 9 is fixedly installed at the bottom end of the top base frame 2. The position of the material ejection assembly 6 is set as the material ejection station, and the position of the arc-shaped rack 7 is set as the material feeding station.

[0038] The indexing mechanism 4 includes two symmetrically distributed indexing shafts 41, which are rotatably mounted at both ends of the mounting bracket 3. An indexing sprocket 42 is fixedly mounted at the bottom of the indexing shaft 41, and an indexing chain 43 is meshed with the outer sides of the two indexing sprockets 42. The drive end of the second motor 9 and the top end of one of the indexing shafts 41 are coaxially fixedly mounted. In use, the second motor 9 is turned on to drive one of the indexing shafts 41 to rotate, thereby driving the indexing sprocket 42 to rotate, which in turn drives the indexing sprocket 42 to drive the transmission, thereby driving multiple positioning mechanisms 5 to drive the transmission, which facilitates subsequent multi-station continuous spraying operations on multiple gate valve frames.

[0039] The positioning mechanism 5 includes a mounting base 51, which is fixedly mounted on the outside of the indexing sprocket 42. A rotating seat 52 is fixedly mounted on the end of the mounting base 51. A bearing 53 is fixedly mounted on the side of the rotating seat 52 away from the mounting base 51. A rotating cylinder 54 is fixedly mounted in the middle of the bearing 53. The rotating cylinder 54 can rotate on the rotating seat 52. A positioning disk 55 is fixedly mounted on the bottom end of the rotating cylinder 54. A positioning outer cylinder 56 is fixedly mounted in the middle of the bottom end of the positioning disk 55.

[0040] The bottom of the positioning outer cylinder 56 is slidably fitted with a plurality of positioning frames 57 arranged in a circular array. The opposite ends of the plurality of positioning frames 57 extend into the positioning outer cylinder 56. A drive disk 58, which cooperates with the positioning frames 57, is rotatably mounted in the positioning outer cylinder 56. The lower surface of the drive disk 58 contacts the upper surfaces of the plurality of positioning frames 57. The lower surface of the drive disk 58 is integrally formed with a planar threaded protrusion. The upper surfaces of the plurality of positioning frames 57 are provided with planar threaded grooves that cooperate with the planar threaded protrusion. The planar threaded protrusion is movably engaged in the planar threaded grooves. A second shaft 510 is fixedly mounted at the center of the top of the drive disk 58. The second shaft 510 moves through the positioning disc 55 and the rotating cylinder 54. By driving the second shaft 510 to rotate, the driving disc 58 is driven to rotate. It is engaged with the planar threaded protrusion in the planar threaded groove, and simultaneously drives multiple positioning frames 57 to slide in opposite directions. In use, the gate valve outer frame is placed on the outside of the positioning outer cylinder 56 at the feeding station. Through the backward sliding of the multiple positioning frames 57, the gate valve outer frame is internally supported and positioned, which facilitates stable transmission of the gate valve outer frame. When the rotating cylinder 54 rotates, it drives the positioning outer cylinder 56 and the gate valve outer frame to rotate, which facilitates the rotary spraying of anti-rust coating on the gate valve outer frame and improves the efficiency of gate valve outer frame spraying.

[0041] The outer top of the rotating cylinder 54 is fixedly fitted with a second gear 511, and the outer side of the mounting top frame 3 is fixedly installed with an external toothed ring frame 8. The second gear 511 in the multiple positioning mechanisms 5 is meshed with the outer side of the external toothed ring frame 8. When the indexing sprocket 42 drives the multiple positioning mechanisms 5 to perform transmission, the external toothed ring frame 8 drives the second gear 511 to rotate synchronously due to the meshing connection between the second gear 511 and the outer side of the external toothed ring frame 8, thereby driving the rotating cylinder 54 to rotate on the rotating seat 52.

[0042] A third gear 512 is fixedly sleeved on the top of the second shaft 510. The ejector assembly 6 includes two electric telescopic rods 61, which are fixedly installed on one side of the mounting bracket 3. A connecting frame 62 is fixedly installed on the drive end of the electric telescopic rod 61, and an ejector rack 63 is fixedly installed on the top of the connecting frame 62. The position of the ejector rack 63 corresponds horizontally to the position of the third gear 512. The third gear 512 in the plurality of positioning mechanisms 5 can mesh with the side of the ejector rack 63 near the mounting bracket 3. When the gate valve outer frame is finished with spraying, it is moved to the ejector station. When the control opens the electric telescopic rod 61, it drives the connecting frame 62 and the ejector rack 63 to move closer to the mounting top frame 3, so that the third gear 512 on the corresponding positioning mechanism 5 and the ejector rack 63 mesh and connect. When the gate valve outer frame continues to drive, the ejector rack 63 drives the corresponding third gear 512 to rotate in the opposite direction, thereby driving the second shaft 510 to rotate in the opposite direction, driving the drive disc 58 to rotate in the opposite direction. It works in conjunction with the planar threaded convex movable engagement in the planar threaded groove, synchronously driving multiple positioning frames 57 to slide towards each other. The gate valve outer frame loses its positioning and automatically disengages from the positioning mechanism 5 under its own gravity to automatically eject material.

[0043] A fixing frame 71 is fixedly installed on the inner side of the arc-shaped rack 7. The fixing frame 71 is fixedly installed on the side of the mounting top frame 3 near the unloading assembly 6. The position of the arc-shaped rack 7 and the position of the third gear 512 are horizontally corresponding. The third gear 512 of the multiple positioning mechanisms 5 can mesh with the side of the arc-shaped rack 7 away from the mounting top frame 3. When the positioning mechanism 5 after automatic unloading moves to the feeding station, it puts the gate valve outer frame on the outside of the positioning outer cylinder 56. The positioning mechanism 5 continues to drive with the gate valve outer frame. The corresponding third gear 512 meshes with the arc-shaped rack 7. When the gate valve outer frame continues to drive, the arc-shaped rack 7 drives the corresponding third gear 512 to rotate, drives the second shaft 510 to rotate, drives the drive disk 58 to rotate, and uses a planar threaded convex movable snap-fit ​​in the planar threaded groove to synchronously drive multiple positioning frames 57 to slide in opposite directions, and automatically internally support and position the gate valve outer frame.

[0044] Working principle: When the processing equipment for the rust-proof gate valve is in use, the control opens the second motor 9 to drive one of the indexing shafts 41 to rotate, thereby driving the indexing sprocket 42 to rotate, which in turn drives the indexing sprocket 42 to drive the transmission, thereby driving multiple positioning mechanisms 5 to perform transmission.

[0045] When the positioning mechanism 5 moves to the feeding station, it places the gate valve outer frame on the outside of the positioning outer cylinder 56. The positioning mechanism 5 continues to drive the gate valve outer frame, and the corresponding third gear 512 and arc rack 7 mesh with each other. When the gate valve outer frame continues to drive, the arc rack 7 drives the corresponding third gear 512 to rotate, drives the second shaft 510 to rotate, and drives the drive disc 58 to rotate. It is used in conjunction with the planar threaded convex movable engagement in the planar threaded groove, and synchronously drives multiple positioning frames 57 to slide in opposite directions, so as to automatically internally support and position the gate valve outer frame.

[0046] Multiple positioning mechanisms 5 drive the positioning gate valve outer frame to perform transmission. Since the second gear 511 and the outer toothed ring frame 8 are meshed, the outer toothed ring frame 8 drives the second gear 511 to rotate synchronously, thereby driving the rotating cylinder 54 to rotate on the rotating seat 52, driving the positioning outer cylinder 56 and the gate valve outer frame to rotate, which facilitates the rotary spraying of anti-rust coating on the gate valve outer frame and improves the efficiency of gate valve outer frame spraying.

[0047] When the gate valve outer frame is finished with spraying and moved to the unloading station, the control opens the electric telescopic rod 61 to drive the connecting frame 62 and the unloading rack 63 to move closer to the mounting top frame 3. This causes the third gear 512 on the corresponding positioning mechanism 5 and the unloading rack 63 to mesh and connect. When the gate valve outer frame continues to move, the unloading rack 63 drives the corresponding third gear 512 to rotate in the opposite direction, thereby driving the second shaft 510 to rotate in the opposite direction and driving the drive disc 58 to rotate in the opposite direction. The planar threaded convex is engaged in the planar threaded groove, and the multiple positioning frames 57 are driven to slide towards each other synchronously. The gate valve outer frame loses its positioning and automatically disengages from the positioning mechanism 5 under its own gravity for automatic unloading.
