Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to an auxiliary device for external plastic coating of steel pipes. Background Technology

[0002] Plastic-coated steel pipe, also known as plastic-coated pipe, steel-plastic composite pipe, or plastic-coated composite steel pipe, is a steel-plastic composite steel pipe with a steel pipe as the base material. A layer of plastic anti-corrosion layer is fused to the inner surface of the steel pipe (base pipe) or the inner and outer surfaces through spraying, rolling, dipping, or suction processes. Plastic-coated steel pipe has excellent corrosion resistance and relatively low frictional resistance. Epoxy resin plastic-coated steel pipe is suitable for conveying media such as water supply and drainage, seawater, warm water, oil, and gas. Polyvinyl chloride plastic-coated steel pipe is suitable for conveying media such as drainage, seawater, oil, and gas.

[0003] In existing technologies, when coating steel pipes with plastic, it is mostly necessary to use a gantry crane to hoist the steel pipes onto the processing equipment. However, hoisting can easily cause the steel pipes to sway, resulting in poor stability, which is not conducive to the current use of steel pipe plastic coating processing. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. In the prior art, when coating steel pipes with plastic, it is mostly necessary to use a gantry crane to hoist the steel pipes onto the processing equipment. However, hoisting can easily cause the steel pipes to swing and have poor stability, which is not conducive to the current steel pipe coating processing. Therefore, an auxiliary device for external plastic coating of steel pipes is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A steel pipe external plastic coating auxiliary device includes a box and a lower slide plate, wherein the lower slide plate is fixedly connected to one side of the box; The housing is slidably connected to a moving block, and a feeding component is installed on the moving block. The feeding component includes a rotating shaft, a connecting plate, a disc, and a push plate. One end of the rotating shaft is rotatably connected to the moving block, one end of the connecting plate is slidably connected to the rotating shaft, and the disc is rotatably connected to the other end of the connecting plate. Two through slots are opened on the disc, and two push plates are slidably connected in the through slots respectively. An arc-shaped plate is fixedly connected to the end of the push plate away from the disc.

[0006] Preferably, the unloading component further includes a fixed plate, a hydraulic cylinder, a gear, and a rack plate. The gear is fixedly connected to the rotating shaft. One end of the fixed plate is fixedly connected to the moving block. A limit box is fixedly connected to the moving block. The rack plate is slidably connected to the limit box. The hydraulic cylinder is fixedly connected to the fixed plate and the rack plate. The rack plate is meshed with the gear.

[0007] Preferably, a support plate is fixedly connected to one side of the moving block, and two servo motors are fixedly connected to the support plate.

[0008] Preferably, two rotating rollers are rotatably connected to the moving block, and the two rotating rollers are respectively fixedly connected to the drive shaft of the servo motor, with a steel pipe slidably connected between the two rotating rollers.

[0009] Preferably, a square box is fixedly connected to the fixed plate, a piston plate is slidably connected to the square box, and the end of the piston plate away from the square box is fixedly connected to the rack plate.

[0010] Preferably, a connecting pipe is fixedly connected between the square box and the disc, and an exhaust port is provided on the disc.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The hydraulic cylinder retracts and pulls the rack plate downward. When the rack plate moves downward, it first pushes the piston plate downward in the square box and squeezes the gas in the square box into the disc through the connecting pipe. As the gas in the disc increases, it pushes the two push plates away from each other. When the arc plate moves with the push plate, it can fit against the inner wall of the steel pipe, thereby achieving the effect of fixing the steel pipe. The disc's fixation of the steel pipe can prevent shaking when the steel pipe is unloaded.

[0012] 2. As the rack plate continues to move downward, the teeth on the rack plate can mesh with the gear, so the rack plate can drive the gear to rotate. When the shaft rotates counterclockwise with the gear, it can drive the disc to move in a circular motion through the connecting plate. When the steel pipe moves in a circular motion with the disc, it can be placed on the sliding plate to realize the feeding of the steel pipe. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0017] Reference Figure 1 A steel pipe external plastic coating auxiliary device includes a box body 1 and a lower slide plate 2, the lower slide plate 2 being fixedly connected to one side of the box body 1.

[0018] Reference Figures 1-4 The housing 1 is slidably connected to a movable block 17, and a feeding component is installed on the movable block 17. The feeding component includes a rotating shaft 19, a connecting plate 9, a disc 4, and a push plate 14. One end of the rotating shaft 19 is rotatably connected to the movable block 17, and one end of the connecting plate 9 is slidably connected to the rotating shaft 19. The connecting plate 9 can only move horizontally on the rotating shaft 19 and will not rotate on the rotating shaft 19. The disc 4 is rotatably connected to the other end of the connecting plate 9. Two through slots are opened on the disc 4, and two push plates 14 are slidably connected in the through slots respectively. An arc plate 20 is fixedly connected to the end of the push plate 14 away from the disc 4. The gas entering the disc 4 can push the push plate 14 to move, thereby causing the two arc plates 20 to move away from each other.

[0019] Reference Figures 1-2 The unloading component also includes a fixed plate 15, a hydraulic cylinder 8, a gear 10, and a rack plate 18. The gear 10 is fixedly connected to the rotating shaft 19. One end of the fixed plate 15 is fixedly connected to the moving block 17. A limit box 16 is fixedly connected to the moving block 17. The rack plate 18 is slidably connected to the limit box 16. The limit box 16 can limit the rack plate 18, allowing the rack plate 18 to move vertically. The hydraulic cylinder 8 is fixedly connected to the fixed plate 15. The hydraulic cylinder 8 is fixedly connected to the rack plate 18, and the rack plate 18 is meshed with the gear 10.

[0020] Reference Figure 2A square box 13 is fixedly connected to the fixed plate 15. A piston plate 12 is slidably connected to the square box 13. The end of the piston plate 12 away from the square box 13 is fixedly connected to the rack plate 18. A connecting pipe 11 is fixedly connected between the square box 13 and the disc 4. An exhaust port is provided on the disc 4. When the rack plate 18 squeezes the piston plate 12 to move inside the square box 13, it can squeeze the gas inside the square box 13 into the disc 4. At the same time, the gas inside the disc 4 will be continuously discharged through the exhaust port, thereby achieving a balance between the gas entering and the gas being discharged.

[0021] Reference Figures 1-2 A support plate 7 is fixedly connected to one side of the moving block 17. Two servo motors 6 are fixedly connected to the support plate 7. Two rotating rollers 5 are rotatably connected to the moving block 17. The two rotating rollers 5 are fixedly connected to the drive shafts of the servo motors 6 respectively. A steel pipe 3 is slidably connected between the two rotating rollers 5.

[0022] In this utility model, during use, the attached... Figure 1 As shown, all components installed on the moving block 17 are symmetrically arranged so that the structures on both sides of the box 1 are the same. The two ends of the steel pipe 3 are placed between the two rotating rollers 5 respectively, and the two servo motors 6 are driven to rotate synchronously, which can drive the steel pipe 3 to rotate stably, which is beneficial for the plastic coating process of the steel pipe 3.

[0023] After the steel pipe 3 is processed, the hydraulic cylinder 8 is driven to retract and pull the rack plate 18 down. When the rack plate 18 moves down, it first pushes the piston plate 12 down in the square box 13 and squeezes the gas in the square box 13 into the disc 4 through the connecting pipe 11. As the gas in the disc 4 increases, it pushes the two push plates 14 away from each other. When the arc plate 20 moves with the push plate 14, it can fit against the inner wall of the steel pipe 3, thereby achieving the effect of fixing the steel pipe 3.

[0024] As the rack plate 18 continues to move downward, the teeth on the rack plate 18 can mesh with the gear 10, so the rack plate 18 can drive the gear 10 to rotate. When the rotating shaft 19 rotates counterclockwise with the gear 10, it can drive the disc 4 to move in a circular motion through the connecting plate 9. When the steel pipe 3 moves in a circular motion with the disc 4, it can be placed on the lower slide plate 2. Then the hydraulic cylinder 8 is stopped. At this time, the gas in the disc 4 is discharged through the through hole and becomes the same as the outside gas. At this time, the arc plate 20 no longer exerts a squeezing force on the steel pipe 3. Then the connecting plate 9 is pulled to slide horizontally on the rotating shaft 19, thereby causing the disc 4 to separate from the steel pipe 3. The steel pipe 3 can slide down the lower slide plate 2 to the ground. The disc 4 fixes the steel pipe 3 to prevent the steel pipe 3 from shaking when it is unloaded.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
