Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass reinforced plastic (FRP) pipe surface treatment equipment, and in particular to a surface treatment device for FRP pipes. Background Technology

[0002] Fiberglass is a fiber-reinforced plastic, generally referring to reinforced plastics that use glass fibers to reinforce unsaturated polyester, epoxy resin, and phenolic resin matrices, with glass fibers or their products as reinforcing materials. It is called glass fiber reinforced plastic, or fiberglass, and is different from tempered glass.

[0003] Fiberglass reinforced plastic (FRP) pipe is a new type of composite material made of resin as the matrix material, glass fiber and its products as the reinforcing material, and quartz sand as the filler material.

[0004] With its excellent corrosion resistance, hydraulic properties, lightweight and high strength, large flow rate, convenient installation, short construction period and low overall investment, it has become the best choice for chemical industry, drainage engineering and pipeline engineering.

[0005] When used in the chemical industry, the inner surface of the fiberglass reinforced plastic (FRP) pipe is usually ground and cleaned, and then a corrosion-resistant coating is sprayed on it to make the FRP pipe suitable for highly corrosive chemical solutions such as strong acids and strong alkalis.

[0006] To facilitate the installation of two fiberglass reinforced plastic (FRP) pipes, the pipe openings of existing FRP pipes are mostly tapered. However, existing technology makes it difficult to grind the tapered surface at the corners with equal force, which easily leads to uneven grinding. As a result, when spraying the corrosion-resistant coating later, the coating may not adhere evenly or may even fail to adhere to the inner surface of the pipe. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a surface treatment device for fiberglass reinforced plastic (FRP) pipes with sand filling, so as to solve the technical problems mentioned in the background art.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A surface treatment device for fiberglass reinforced plastic (FRP) sand-filled pipe includes a connecting shaft. Several rotating frames are arranged in a ring array on both ends of the connecting shaft. An adjusting rod is rotatably arranged inside the rotating frame. The adjusting rod has a sliding groove inside and is located at both ends of the connecting shaft. The adjusting rods arranged on two corresponding rotating frames intersect each other, and a limit rotating shaft is provided at the intersection of two sliding grooves.

[0010] The connecting shaft has a sliding cavity inside, and the cavity wall of the sliding cavity has a positioning groove that passes through the connecting shaft at a position corresponding to the rotating frame. The sliding cavity has a sliding plate inside, and a hydraulic telescopic rod that inserts into the positioning groove is provided on the outer periphery of the sliding plate. The top end of the hydraulic telescopic rod is rotatably connected to the limiting rotating shaft. The ends of the two intersecting adjusting rods away from the rotating frame are jointly provided with a sanding belt mounting bracket.

[0011] Furthermore, the outer surface of the limiting shaft is rotatably provided with two sliding blocks, and the two sliding blocks are respectively embedded in the interior of the sliding groove. The groove wall of the sliding groove is provided with a guide rail, and the side wall of the sliding block is provided with a guide groove that slides with the guide rail.

[0012] Furthermore, the sliding plate has an internal threaded hole in the middle, and a threaded rod is connected to the internal thread of the internal threaded hole. Both ends of the threaded rod are rotatably connected to the connecting shaft through bearings.

[0013] Furthermore, one end of the threaded rod passes through the connecting shaft, and a drive motor is provided at the end of the threaded rod that passes through the connecting shaft.

[0014] Furthermore, the sanding belt mounting frame includes two rotating shafts, which are respectively mounted on the ends of two intersecting adjusting rods away from the rotating frame. Each rotating shaft has a first guide wheel on its outer periphery and an extension rod at one end of each rotating shaft. The extension rod is an elastic telescopic rod, and the ends of the two extension rods away from the rotating shafts are rotatably connected to each other, with a second guide wheel at the connection point.

[0015] Furthermore, the outer surfaces of the two first guide wheels and the second guide wheel are jointly fitted with a sanding belt.

[0016] In summary, this utility model has at least one of the following beneficial technical effects:

[0017] 1. The surface treatment device for fiberglass reinforced plastic (FRP) sand-filled pipes, when the sliding plate is located at the center of the sliding cavity, the relative positions of the limiting rotating shaft and the two adjusting rods are the same. At this time, by setting the hydraulic telescopic rod, the angle between the straight direction of the adjusting rod and the straight direction of the connecting shaft can be changed, so as to change the distance between the end of the adjusting rod away from the rotating frame and the surface of the connecting shaft, so that the device can adapt to the effect of pipes with different diameters.

[0018] 2. This fiberglass reinforced plastic (FRP) sand-filled pipe surface treatment device, when the pipe has an inclined surface due to the change in pipe diameter, pushes the sliding plate so that the position of the sliding plate intersects with the center of the sliding cavity, so that the relative positions of the limiting rotating shaft and the two adjusting rods are different. At this time, the line connecting the ends of the two adjusting rods away from the rotating frame forms an angle with the axis of the connecting shaft, so as to achieve the purpose of grinding the pipe diameter change.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0028] Reference Figure 1 - Figure 6The present invention discloses a surface treatment device for fiberglass reinforced plastic (FRP) sand-filled pipe, including a connecting shaft 1. Several rotating frames 2 are arranged in a ring array on both ends of the connecting shaft 1. An adjusting rod 3 is rotatably arranged inside the rotating frame 2. The adjusting rod 3 has a sliding groove 4 inside, located at both ends of the connecting shaft 1. The adjusting rods 3 arranged on the corresponding two rotating frames 2 intersect each other, and a limiting rotating shaft 5 is provided at the intersection of the two sliding grooves 4.

[0029] The connecting shaft 1 has a sliding cavity 6 inside, and the cavity wall of the sliding cavity 6 has a positioning groove 7 that passes through the connecting shaft 1 at a position corresponding to the rotating frame 2. The sliding cavity 6 has a sliding plate 8 inside, and the outer periphery of the sliding plate 8 has a hydraulic telescopic rod 9 that is inserted into the positioning groove 7. The top end of the hydraulic telescopic rod 9 is rotatably connected to the limiting rotating shaft 5. The ends of the two intersecting adjusting rods 3 away from the rotating frame 2 are jointly provided with a sanding belt mounting bracket 10.

[0030] In this embodiment, during use, the connecting shaft 1 is installed on the drive shaft of the servo motor. The servo motor drives the connecting shaft 1 to rotate, causing the adjusting rod 3 and the sanding belt mounting bracket 10 to perform circular motion. This rotation serves to grind the pipe wall. When the pipe exhibits a slope due to changes in pipe diameter, the position of the sliding plate 8 within the sliding cavity 6 is adjusted to control the angle of the two adjusting rods 3. Figure 6 As shown, by changing the relative position of the two adjusting rods 3, the line connecting the ends of the two adjusting rods 3 away from the rotating frame 2 forms an angle with the axis of the connecting shaft 1, so as to achieve the purpose of grinding the part where the pipe diameter changes.

[0031] Specifically, when the sliding plate 8 is located at the center of the sliding cavity 6, the relative positions of the limiting shaft 5 and the two adjusting rods 3 are the same, such as... Figure 3 As shown, by setting the hydraulic telescopic rod 9, the angle between the straight direction of the adjusting rod 3 and the straight direction of the connecting shaft 1 can be changed, thereby changing the distance between the end of the adjusting rod 3 away from the rotating frame 2 and the surface of the connecting shaft 1, so that the device can adapt to pipes of different diameters.

[0032] On the other hand, when the pipe exhibits an inclined plane due to a change in pipe diameter, the sliding plate 8 is pushed, causing its position to intersect with the center of the sliding cavity 6, such as... Figure 6 As shown, the relative positions of the limiting rotating shaft 5 and the two adjusting rods 3 are different. At this time, the line connecting the ends of the two adjusting rods 3 away from the rotating frame 2 forms an angle with the axis of the connecting shaft 1, so as to achieve the purpose of grinding the part where the pipe diameter changes.

[0033] In a further preferred embodiment of this utility model, such as Figure 1-6As shown, two sliding blocks 11 are rotatably provided on the outer surface of the limiting shaft 5, and the two sliding blocks 11 are respectively embedded in the interior of the sliding groove 4. The groove wall of the sliding groove 4 is provided with a guide rail 12, and the side wall of the sliding block 11 is provided with a guide groove 13 that slides with the guide rail 12.

[0034] In this embodiment, the limiting pivot 5 ensures that the two adjusting rods 3 always have an intersection point, and the two sliding blocks 11 are respectively embedded in the two sliding grooves 4 to improve the stability between the adjusting rods 3 and the limiting pivot 5. The guide rail 12 and the guide groove 13 are used to limit the sliding blocks 11 and prevent the sliding blocks 11 from falling out of the sliding grooves 4.

[0035] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the sliding plate 8 has an internal threaded hole 14 in the middle, and a threaded rod 15 is threadedly connected inside the internal threaded hole 14. Both ends of the threaded rod 15 are rotatably connected to the connecting shaft 1 through bearings.

[0036] In this embodiment, the threaded rod 15 is installed through the internal threaded hole 14. By rotating the threaded rod 15 to cooperate with the internal threaded hole 14, the sliding plate 8 is pushed to move.

[0037] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, one end of the threaded rod 15 passes through the connecting shaft 1, and a drive motor 16 is provided at the end of the threaded rod 15 that passes through the connecting shaft 1.

[0038] In this embodiment, the drive motor 16 is used to drive the threaded rod 15 to rotate, so as to quickly push the mounting sliding plate 8 to move.

[0039] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the sanding belt mounting frame 10 includes two mounting shafts. The two mounting shafts are respectively mounted on the ends of two intersecting adjusting rods 3 away from the rotating frame 2. Each mounting shaft has a first guide wheel 102 on its outer periphery. Each mounting shaft has an extension rod 103 at one end. The extension rod 103 is an elastic telescopic rod, and the ends of the two extension rods 103 away from the mounting shafts are rotatably connected to each other. A second guide wheel 104 is provided at the connection point.

[0040] In this embodiment, two extension rods 103, which are elastic telescopic rods, are used in conjunction with two first guide wheels 102 and two second guide wheels 104 to form a triangle with a variable circumference. Thus, when the sanding belt 105 is fitted onto the outer surface of the first guide wheels 102 and the second guide wheels 104, the sanding belt 105 can always be kept taut, thereby improving the uniformity of sanding.

[0041] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the outer surfaces of the two first guide wheels 102 and the second guide wheel 104 are jointly fitted with a sanding belt 105.

[0042] In this embodiment, since the extension rod 103 is an elastic telescopic rod, it can effectively tighten the sanding belt 105, and can also retract it by pressing the extension rod 103, thereby facilitating the replacement of the sanding belt 105.

[0043] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
