Description

Technical Field

[0001] This utility model relates to the field of steel pipe rust removal technology, specifically a steel pipe rust removal feeding device. Background Technology

[0002] Seamless steel pipes are primarily used for transporting fluids and gases, possessing excellent airtightness and mechanical properties. However, like other steel materials, seamless steel pipes are prone to corrosion, necessitating the application of anti-rust paint to their outer surface. Before painting, a rust removal process is required. Existing rust removal devices typically deliver steel pipes one by one to the rust removal station via a guide rail. However, this method is prone to impacts, leading to pipe accumulation and hindering the rust removal process. Furthermore, it is inconvenient to separate multiple pipes. Existing pipe feeding devices also utilize a bottom conveyor belt, but this method suffers from poor stability and is prone to pipe movement. Therefore, a rust removal feeding device is designed to facilitate stable, single-pipe feeding, preventing pipe accumulation and ensuring convenient rust removal. Utility Model Content

[0022] 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.

[0023] Example:

[0024] Please see Figure 1-6 A steel pipe rust removal and feeding device includes a support frame 1. The top of the support frame 1 is symmetrically provided with adjustable-spaced slides 2. The bottom of each slide 2 is provided with parallel feeding racks 3. Each feeding rack 3 is equipped with a conveyor. Multiple pipe end rotating support mechanisms are installed circumferentially on the conveyor. A steel pipe outer wall rust removal mechanism that can be detached between the two slides 2 is provided above the middle position of the two conveyors. An L-shaped guide plate 19 and a flat guide plate 21 are fixedly installed on both sides of each feeding rack 3, and a busbar 20 is provided on the L-shaped guide plate 19.

[0025] Specifically, the conveyor includes a conveyor chain and a feeding motor 15. The pipe end rotating support mechanism includes a fixed frame 4 fixedly installed on the chain links of the conveyor chain. Sliding columns 6 are laterally slidably connected to the fixed frame 4. The outer ends of multiple sliding columns 6 are fixedly connected by a sliding plate 5. Limit blocks 8 are fixedly installed on the inner ends of the sliding columns 6. Springs 7 are sleeved on the sliding columns 6, and the two ends of the springs 7 are fixedly connected to the fixed frame 4 and the sliding plate 5 respectively. An inner support column 9 is rotatably connected to the outward end of the sliding plate 5, and the free end of the inner support column 9 is set as an arc shape, so that steel can be easily inserted through the inner support column 9. Inside the pipe end, the inner support column 9 can be elastically extended and retracted towards the conveyor side by the spring 7, which facilitates the insertion of the steel pipe and ensures the stability of the conveying. Furthermore, the feeding frame 3 is rotatably connected to the conveyor chain roller that supports the conveying strip. The output shaft of the feeding motor 15 is fixedly connected to one of the conveyor chain rollers. Starting the feeding motor 15 can easily drive the conveying strip to rotate, thereby driving the pipe end rotation support mechanism to rotate. Furthermore, the feeding frame 3 also includes a support frame that supports the conveying chain to ensure the stability of the steel pipe during the conveying process.

[0026] Specifically, the steel pipe outer wall rust removal mechanism includes multiple grinding rollers 11 arranged in sequence. Each grinding roller 11 has a fixing strip 10 at both ends, and one side of each grinding roller 11 is rotatably connected to the fixing strip 10 on the same side. Both slides 2 are provided with slots that engage with the fixing strips 10. The multiple grinding rollers 11 facilitate pre-rust removal and grinding of the steel pipe when it passes through from the bottom. The engagement of the slots with the fixing strips 10 facilitates the disassembly and replacement of the multiple grinding rollers 11, thereby making it easy to replace grinding rollers 11 of different lengths to suit the feeding operation of steel pipes of different lengths.

[0027] Specifically, the slide 2 is equipped with a lifting mechanism for lifting the grinding rollers 11. The lifting mechanism includes a lifting slider 12 that slides vertically on the slide 2. A slot is provided on the lifting slider 12. A one-way screw 13 that is threadedly connected to the lifting slider 12 is vertically rotatably connected to the slide 2. An adjustment knob 14 is fixedly installed at one end of the one-way screw 13. By rotating the adjustment knob 14, the one-way screw 13 can be rotated, which can drive the lifting slider 12 to perform lifting and lowering operations. This allows for the adjustment of the slot, thereby allowing for the lifting and lowering of the fixing bar 10 and multiple grinding rollers 11. This facilitates the adjustment of the vertical distance between the grinding rollers 11 and the steel pipe being conveyed.

[0028] Specifically, the support frame 1 also includes a spacing adjustment mechanism for adjusting the distance between the two slides 2. The spacing adjustment mechanism includes a bidirectional screw 16 rotatably connected to the support frame 1. The two slides 2 are symmetrically threaded to the bidirectional screw 16 and both slides 2 are guided and slidably engaged with the support frame 1. An adjustment motor 17 that drives the bidirectional screw 16 to rotate is fixedly installed on the support frame 1. When the adjustment motor 17 is started, the output shaft of the adjustment motor 17 rotates clockwise or counterclockwise, thereby driving the bidirectional screw 16 to rotate clockwise or counterclockwise, thereby driving the two slides 2 to rotate towards the middle or towards both sides.

[0029] Specifically, it also includes a guide rod 18 fixedly installed on the support frame 1. Both slides 2 are guided and slidably engaged with the guide rod 18. The guide rod 18 facilitates the support of the two slides 2 and increases the stability of the two slides 2.
