Technical Field

[0001] The utility model relates to the technical field of steel-plastic composite pipe processing, in particular to a fixing device used for steel-plastic composite pipe processing. Background Art

[0002] Steel-plastic composite pipes are based on seamless steel pipes and welded steel pipes. The inner wall is coated with high-adhesion, corrosion-resistant, food-grade hygienic polyethylene powder coating or epoxy T-grease coating. The water supply galvanized inner plastic-coated composite steel pipe is made through pre-treatment, preheating, internal coating, leveling, and post-treatment processes. It is an upgraded product of the traditional galvanized pipe. Steel-plastic composite pipes are generally connected by thread, groove, and flange. In the existing steel-plastic composite pipe processing process, it is often necessary to use a fixing device to fix composite pipes of different diameters. However, most of the existing fixing devices for steel-plastic composite pipe processing are difficult to fix composite pipes of different diameters, which is inconvenient to process. In view of the existing situation, a fixing device for steel-plastic composite pipe processing is proposed to solve the above-mentioned problems.

The utility model solves the problem that the existing fixing device for processing steel-plastic composite pipes usually does not have the function of adjusting the length of the steel-plastic composite pipe during use, and the angle of the steel-plastic composite pipe cannot be adjusted during the processing, which may cause certain inconvenience to the user.

[0004] However, there are deficiencies: the device can adjust the length of the steel-plastic composite pipe during use, and can adjust the angle of the steel-plastic composite pipe processing, but it is difficult for the device to fix composite pipes of different diameters, which is inconvenient for processing.

The two large swing arms are closed one by one, thereby having a restraining effect on the steel-plastic composite pipe and being able to adapt to steel-plastic composite pipes of different diameters.

[0028] See also Figure 1-Figure 5 As shown, the utility model is a fixing device for processing steel-plastic composite pipes, comprising a base column 1, a movable structure 2 is fixedly connected to the upper side of the base column 1, and a supporting structure 3 is movably connected to the outer side of the movable structure 2;

[0029] The mobile structure 2 includes a mobile frame 201, which is fixedly mounted on the top of the base column 1. A mobile motor 203 is fixedly mounted on the outer surface of the mobile frame 201. A motor output shaft 202 is mounted on the output end of the mobile motor 203. One end of the motor output shaft 202 is fixedly connected to a bidirectional screw rod 204. A motor base column is fixedly mounted on the outer surface of the frame 201. The mobile motor 203 is fixedly mounted on the upper surface of the motor base column to provide a stable support force for the mobile motor 203. Two sliding rods 205 are fixedly connected between the inner walls of the mobile frame 201. The sliding rods 205 are arranged parallel to the bidirectional screw rods 204 and pass through the supporting base columns 301 in sequence to ensure that the two supporting base columns 301 can stably move relative to or opposite to each other along the direction of the sliding rods 205.

[0030] The supporting structure 3 includes two supporting base columns 301, which are threadedly installed on the outer surface of the bidirectional screw rod 204. The outer surface of the supporting base column 301 is fixedly installed with a cylinder 303, and the output end of the cylinder 303 is fixedly installed with a T-shaped plate 305. The outer surface of the supporting base column 301 is rotatably installed with a rotating part 307, and the outer surface of the rotating part 307 is installed with a large swing arm 308 and a small swing arm 304. The outer surface of the T-shaped plate 305 is provided with two inclined plates, which are arranged to abut against the small swing arm 304.

[0031] A first roller 306 is provided on the upper surface of the supporting base column 301, and a second roller 309 is installed at one end of the large swing arm 308. When in use, the steel-plastic composite pipe is placed between the two second rollers 309, and the pipe wall of the steel-plastic composite pipe is against the first roller 306 and the two second rollers 309. The provided rollers can effectively prevent the pipe wall of the steel-plastic composite pipe from being scratched.

[0032] A third roller 302 is installed at one end of the small swing arm 304 close to the T-shaped plate 305, and a coil spring 310 is provided in the rotating part 307. The two coil springs 310 rotate in opposite directions, so that the two small swing arms 304 always have a tendency to move relative to each other.

[0033] The rotating part 307 is a cylindrical sleeve with a cavity inside. A connecting column 311 is fixedly installed in the rotating part 307.

[0034] By setting the coil spring 310, the third roller 302 always contacts the T-shaped plate 306, and when the T-shaped plate 305 moves up and down, the two large swing arms are ensured to have a tendency to move relative to each other, thereby effectively constraining the steel-plastic composite pipe.

[0035] When in use, first drive the moving motor 203 according to work requirements, and the moving motor 203 drives the bidirectional screw rod 204 to rotate, so that the two supporting base columns 301 threadedly installed on the bidirectional screw rod 204 are moved relative to each other, thereby adjusting the distance between the two supporting base columns 301 to adapt to steel-plastic composite pipes of different lengths, expanding the scope of application of the device and improving practicality.

[0036] When the device is in use, the cylinder 303 is first started to move the T-shaped plate 305 upward to its maximum value. Under the elastic force of the coil spring 310, the small swing arm 304 always contacts the T-shaped plate 305. As the T-shaped plate 305 moves upward, the two large swing arms 308 are opened to the maximum value. At this time, the steel-plastic composite pipe is placed between the two large swing arms 308, and then the cylinder 303 is started to gradually move the T-shaped plate 305 downward. The two large swing arms 308 are closed one by one, thereby constraining the steel-plastic composite pipe and being able to adapt to steel-plastic composite pipes of different diameters.
