Description

Technical Field

[0001] The utility model relates to special equipment for polishing composite pipes FRP-PVC, belonging to the technical field of pipe polishing equipment. Background Art

[0002] Composite pipe FRP / PVC is made of rigid polyvinyl chloride as inner lining and glass fiber reinforced plastic as outer reinforcement layer through fiber winding process. This pipe is mainly used to transport corrosive fluids with temperature of -10℃-80℃ and pressure ≤1.6Mpa. It has the characteristics of acid and alkali corrosion resistance of PVC pipe, and overcomes the low compressive strength of PVC pipe under temperature conditions. PVC pipe only plays the role of medium corrosion resistance, and the compressive strength is completely borne by the FRP reinforcement layer. This kind of pipe has good corrosion resistance, good temperature resistance, low fluid resistance, no electrochemical corrosion, easy installation, and is often used in environments with corrosive media. The excellent characteristics of this composite pipe will replace carbon steel lined rubber pipes in the transportation of low-pressure and corrosive media in chlor-alkali and other chemical production and will be widely promoted and applied.

[0003] During the production process of FRP / PVC composite pipes, in order to ensure the adhesion between the inner lining PVC pipe and the wrapped FRP outer reinforcement layer, the inner lining PVC pipe must be polished to varying degrees before winding. After polishing and cleaning, the interface adhesive is evenly applied, and finally the FRP reinforcement layer is wrapped.

[0004] The lined PVC pipes are polished to different degrees, usually manually. During the polishing process, the speed is very slow, and because the requirements for polishing are different, workers have difficulty controlling manual tools and accidents are prone to occur. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] The utility model is a special equipment for grinding FRP-PVC composite pipes, which is mainly used for grinding the outer surface of the hard polyvinyl chloride pipe in the composite pipe for subsequent processing.

[0021] The equipment includes a grinder, which can grind the lining PVC to different degrees by controlling the extension and retraction of the tool. The main design point is that a pipeline rotation support mechanism is provided for the grinder.

[0022] like Figure 1 As shown, the pipeline rotation support mechanism includes two rotating shafts, respectively named as rotating shaft 1 and rotating shaft 2. Both rotating shaft 1 and rotating shaft 2 are driven to rotate by a motor. Rotating shaft 1 and rotating shaft 2 are set at a distance. The two ends of rotating shaft 1 and rotating shaft 2 are respectively rotatably mounted on the support frame through bearings. The lower part of the support frame here is set on a slide rail, which can slide to change the distance between rotating shaft 1 and rotating shaft 2. The distance between rotating shaft 1 and rotating shaft 2 is used to place the pipeline to be polished. Since the distance between rotating shaft 1 and rotating shaft 2 can be changed, the equipment can be suitable for pipelines of different diameters.

[0023] The distance between the first rotating shaft 1 and the second rotating shaft 2 can be adjusted. Correspondingly, a telescopic rod 3 is provided between the two rotating shafts to adjust the distance between them. Figure 1 As shown, telescopic rods 3 are arranged at both ends of the rotating shaft, and the two ends of the telescopic rod 3 are respectively connected to the rotating shaft 1 and the rotating shaft 2. The telescopic rod 3 adjusts the distance between the rotating shaft 1 and the rotating shaft 2 by telescoping. The telescopic rod 3 arranged here is a hydraulic telescopic rod or a pneumatic telescopic rod, preferably a hydraulic telescopic rod. In a specific implementation, further, the telescopic rod 3 uses a double-head telescopic rod, so that the telescopic rod 3 can be telescoped from the middle to both sides.

[0024] The grinder provided in the arrangement is located below the space between the two rotating shafts, and the grinder can move linearly, so as to grind various positions of the pipeline. To this end, a grinding track 4 is provided, and the grinding track 4 is linearly arranged along the axial direction of the rotating shaft, and the grinder moves linearly on the grinding track 4. Furthermore, a grinding platform 5 can be installed on the grinding track 4, and then the grinder is installed on the grinding platform 5.

[0025] The utility model is also provided with a conveying track 6, through which the polished pipe is conveyed. The feeding end of the conveying track 6 corresponds to the lower part of the space between the two rotating shafts, and after the pipe is polished, the pipe can enter the conveying track 6 and be conveyed forward.

[0026] In actual work, the grinding efficiency of the utility model is very high, which is greatly improved compared with manual grinding. At the same time, the scrap rate is significantly reduced compared with manual operation. The overall use effect is good.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
