Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline rust removal technology, specifically a fixing device for removing rust from the outer wall of a pipeline. Background Technology
[0002] Pipe fixing devices are equipment or structures used to securely fix pipes in a specific position to prevent them from moving, vibrating, or shaking.
[0003] Currently, most existing pipe external wall rust removal devices use clamps to hold the pipe's outer wall for fixation. This method results in some areas of the pipe's outer wall being obstructed by the clamps, making it difficult for operators to grind these areas. This leads to grinding dead spots on the pipe's outer wall, preventing comprehensive rust removal and affecting the rust removal effect and workpiece quality. Therefore, we propose a fixing device for pipe external wall rust removal. Utility Model Content
[0004] The main objective of this invention is to provide a fixing device for removing rust from the outer wall of a pipe, which can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model proposes a fixing device for rust removal from the outer wall of a pipe, comprising a support platform, movable seats at both ends of the support platform, and a fixing mechanism on the movable seats for fixing the pipe. The fixing mechanism includes:
[0006] A rotating wheel has a sliding groove on one side of its outer wall and a sliding groove on the other side of its outer wall. The side wall of the rotating wheel is penetrated by a screw and threadedly connected to the screw. A sliding rod is slidably connected to the end of the screw. The rotating wheel passes through a toothed sleeve and is fixedly connected to the toothed sleeve.
[0007] A rotating disk with an arc-shaped groove is provided. A fixed sleeve passes through the rotating disk and is fixedly connected to the fixed sleeve. A pull rod is fixedly connected to the outer wall of the rotating disk, and the pull rod is slidably connected to the sliding groove.
[0008] A movable block, which is slidably connected to a sliding groove and an arc-shaped groove.
[0009] Preferably, a shaft is fixedly connected to the inner wall of the rotating wheel, and the shaft passes through the fixed sleeve and is rotatably connected to the fixed sleeve.
[0010] Preferably, the shaft passes through the bearing and is fixedly connected to the inner wall of the bearing, and a fixing plate is fixedly connected to the outer wall of the bearing, and the fixing plate is fixedly connected to the outer wall of the movable seat.
[0011] Preferably, a hydraulic cylinder is fixedly connected to the outer wall of the support platform, a support base is fixedly connected to the output end of the hydraulic cylinder, and a roller is rotatably connected to the support base.
[0012] Preferably, the support platform is rotatably connected to a rotating shaft, and the inner wall of the rotating shaft has an inner groove.
[0013] Preferably, a motor is fixedly connected to the outer wall of the movable seat, and a rotating shaft is fixedly connected to the output end of the motor. The rotating shaft passes through a gear and is fixedly connected to the gear, and the gear meshes with a gear sleeve.
[0014] Preferably, the rotating shaft passes through the rotating shaft and is slidably connected to the rotating shaft, and a protrusion is fixedly connected to the outer wall of the rotating shaft, and the protrusion is slidably connected to the inner groove.
[0015] Preferably, a guide rod is fixedly connected to the outer wall of the movable seat, and the guide rod passes through the support seat and is slidably connected to the support seat.
[0016] This utility model provides a fixing device for rust removal from the outer wall of a pipe. It has the following beneficial effects:
[0017] (1) The fixing device for removing rust from the outer wall of the pipe, by clamping the inner wall of the pipe, is different from the way traditional clamps clamp the outer wall of the pipe. It enables the operator to grind and remove rust from the outer wall of the pipe in a comprehensive manner, without any dead corners, which effectively improves the quality and effect of removing rust from the outer wall of the pipe.
[0018] (2) The fixing device for rust removal on the outer wall of the pipe has two sets of rotating wheels, gears and tooth sleeves. The rotation speed of the two sets of rotating wheels can be made consistent by a single set of motors. After one side of the pipe is polished, the rotating wheel drives the pipe to roll and flip through the transmission of the motor, gears and tooth sleeves. This design improves the stability of the pipe flipping and is beneficial to the subsequent rust removal work on the other side of the pipe.
[0019] (3) The pipe outer wall rust removal fixing device has two sets of rotating shafts. The protrusions on the outer wall of the rotating shafts cooperate with the inner grooves opened on the inner wall of the rotating shafts, so that the two sets of rotating shafts can slide on the inner wall of the rotating shafts. By moving the two sets of rotating shafts to both sides, the transmission distance of the device's transmission shaft can be increased, thereby making the device adaptable to pipes of different sizes and greatly improving the applicability of the device.

[0030] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-7 This utility model proposes a fixing device for removing rust from the outer wall of a pipe, including a support platform 1, with movable seats 2 at both ends of the support platform 1. A guide rod 22 is fixedly connected to the outer wall of the movable seat 2. The guide rod 22 passes through the support seat 12 and is slidably connected to the support seat 12 to improve the stability of the movement of the movable seat 2. A fixing mechanism is provided on the movable seat 2 for fixing the pipe.
[0033] In this embodiment of the utility model, in order to clamp the tube body, the fixing mechanism specifically includes a rotating wheel 31. A sliding groove 311 is formed on one outer wall of the rotating wheel 31, and a sliding groove 313 is formed on the other outer wall of the rotating wheel 31. A screw 314 penetrates the side wall of the rotating wheel 31 and is threadedly connected to the screw 314. A sliding rod 315 is slidably connected to the end of the screw 314 to facilitate rotation of the screw 314. The sliding connection design prevents the rotating wheel 31 from obstructing the sliding rod 315. The rotating wheel 31 penetrates the toothed sleeve 32 and is fixedly connected to the toothed sleeve 32. The inner wall of the rotating wheel 31 is fixedly connected to... There is a shaft 312, which passes through the fixed sleeve 341 and is rotatably connected to the fixed sleeve 341. The shaft 312 passes through the bearing 35 and is fixedly connected to the inner wall of the bearing 35. A fixed plate 36 is fixedly connected to the outer wall of the bearing 35. The fixed plate 36 is fixedly connected to the outer wall of the movable seat 2. The rotating disk 34 has an arc-shaped groove 342. The rotating disk 34 is passed through the fixed sleeve 341 and is fixedly connected to the fixed sleeve 341. A pull rod 343 is fixedly connected to the outer wall of the rotating disk 34. The pull rod 343 is slidably connected to the sliding groove 313. The movable block 33 is slidably connected to the sliding groove 311 and the arc-shaped groove 342.
[0034] Furthermore, a hydraulic cylinder 14 is fixedly connected to the outer wall of the support platform 1, a support base 12 is fixedly connected to the output end of the hydraulic cylinder 14, a roller 13 is rotatably connected to the support base 12, and a rotating shaft 11 is rotatably connected to the support platform 1. An inner groove 111 is opened on the inner wall of the rotating shaft 11.
[0035] Furthermore, a motor 21 is fixedly connected to the outer wall of the movable base 2, and a rotating shaft 23 is fixedly connected to the output end of the motor 21. The rotating shaft 23 passes through and is fixedly connected to the gear 24. The gear 24 meshes with the gear sleeve 32. The rotating shaft 23 passes through and is slidably connected to the rotating shaft 11. A protrusion 231 is fixedly connected to the outer wall of the rotating shaft 23, and the protrusion 231 is slidably connected to the inner groove 111.
[0036] In this invention, during use, the pipe is first placed on the support base 12, then the hydraulic cylinder 14 is activated to raise the pipe until the center of the pipe is level with the center of the rotating wheel 31. Then, the moving base 2 is pushed in sequence, so that the moving block 33 enters the pipe and the outer wall of the pipe coincides with the outer wall of the rotating wheel 31. Then, the pull rod 343 is pulled, so that the rotating disk 34 rotates. During this process, the arc groove 342 applies a force to the moving block 33, so that the moving block 33 expands into the inner wall of the pipe until the pipe is fixed. Then, the screw 314 is rotated, so that the bottom of the screw 314 squeezes the outer wall of the fixing sleeve 341, thereby fixing the rotating disk 34. This device clamps the inner wall of the pipe, which, compared with the traditional clamps that clamp the outer wall of the pipe, allows the operator to fully grind and remove rust from the outer wall of the pipe without any grinding dead corners.
[0037] After one side of the pipe is polished, the rotating wheel 31 can be driven by the motor 21 through the gear 24 and the gear sleeve 32 to flip the pipe over. Figure 1 As shown, there are two sets of rotating wheels 31, gears 24 and gear sleeves 32. By controlling a single set of motors 21, the rotation speed of the two sets of rotating wheels 31 can be made the same, thereby improving the stability of pipe flipping.
[0038] like Figure 6 As shown, there are two sets of rotating shafts 23. Through the design of the protrusions 231 on the outer wall of the rotating shaft 23 and the inner grooves 111 opened on the inner wall of the rotating shaft 11, the two sets of rotating shafts 23 can slide on the inner wall of the rotating shaft 11. By moving the two sets of rotating shafts 23 to both sides, the transmission distance of the device's transmission shaft can be increased, making the device adaptable to pipes of different sizes, thereby improving the applicability of the device.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
