The key points of its technical solution include glass fiber reinforced plastic sand-filled pipes, and the left and right sides of the outer wall of the glass fiber reinforced plastic sand-filled pipe are respectively installed with a traction fixing device and an auxiliary fixing device. The traction fixing device and the auxiliary fixing device both include a fixing ring, which is connected to the external traction equipment through a traction hook. The traction hook is connected to the fixing ring of the traction fixing device through multiple traction ropes.

[0031] The present invention will be described in further detail below with reference to the accompanying drawings.

[0032] The working principle of this utility model is as follows Figure 1-Figure 5 As shown, a traction mechanism for glass fiber reinforced plastic production includes a base 1. First, a protection box 3 is fixedly connected to the middle of the top of the base 1, and a positioning shaft 7 is fixedly connected to the middle of both sides of the top of the protection box 3. At the same time, a receiving plate 4 is provided above the protection box 3. The middle of both sides of the top of the receiving plate 4 is provided with a positioning hole 6 for matching the positioning shaft 7. Here, the positioning shaft 7 is inserted into the positioning hole 6. Then, a support column 8 is fixedly connected to the middle of the top of the receiving plate 4, and the top of the support column 8 is fixedly connected to a wheel frame 12, and the wheel frame 12 is also rotatably connected to a rubber Wheel 9, in order to make the displacement of the fiberglass more stable when pulling the fiberglass, a groove 10 for limiting is opened on the wheel part of the outer wall of the rubber wheel 9, and then a transmission device 11 used in conjunction with the rubber wheel 9 is provided at the top of the receiving plate 4. In order to reduce the adverse effects of vibration on the equipment on the receiving plate 4, a shock absorbing device 5 is provided at the bottom end of the receiving plate 4, and the shock absorbing device 5 is also located in the protective box 3. Finally, four universal wheels 2 are fixedly connected to the bottom end of the base 1, among which the universal wheels 2 have a self-locking function, and the four universal wheels 2 are diagonally arranged.

[0033] The above-mentioned structures together constitute the general appearance structure of the traction mechanism for glass fiber reinforced plastic production of the present invention.

[0034] In order to further explain the specific working principle of the traction mechanism for glass fiber reinforced plastic production of the present invention, the transmission device 11 includes a servo motor 1102 located on one side of the rear end of the top end of the receiving plate 4. The servo motor 1102 is fixedly connected to the receiving plate 4 by providing a motor seat 1103. In addition, the servo motor 1102 has a self-locking function. A bidirectional screw 1101 is fixedly connected to the output shaft at the front end of the servo motor 1102, and the front end of the bidirectional screw 1101 is rotatably connected to the rotating frame 1104. The bottom end of the rotating frame 1104 is fixedly connected to the receiving plate 4. In addition, threaded blocks 1105 are threadedly connected to the threaded parts at the front and rear ends of the bidirectional screw 1101, and the two threaded blocks 1105 are both slidably connected to the receiving plate 4. It should be noted that the support column 8 is located between the front and rear threaded blocks 1105. When the servo motor 1102 drives the bidirectional screw 1101 to rotate When the two threaded blocks 1105 are moved toward the adjacent side or the separated side, a fixed plate 1107 is provided above the front and rear threaded blocks 1105, where both sides of the bottom end of each fixed plate 1107 are fixedly connected to a hydraulic telescopic rod 1106, and the hydraulic telescopic rod 1106 has a self-locking function, and then the bottom end of the hydraulic telescopic rod 1106 is fixedly connected to the corresponding threaded block 1105. At the same time, a stepper motor 1108 is provided in the middle of the top of the front and rear fixed plates 1107, and each stepper motor 1108 is fixedly connected to the corresponding fixed plate 1107 through a motor seat 2 1109. Finally, a transmission wheel 1110 is fixedly connected to the output shaft of the front and rear stepper motors 1108, and each transmission wheel 1110 is provided with a groove 2 1111. In addition, an anti-sliding block is fixedly connected to the groove wall of the groove 2 1111.

[0035] The technical effect achieved by the technical solution composed of the above-mentioned technical features is as follows: when the FRP pipe needs to be towed, the FRP pipe is first placed in the groove 10 of the rubber wheel 9, and then the hydraulic telescopic rods 1106 on both sides push the corresponding fixed plate 1107 to a specified height, so that the fixed plate 1107 can indirectly drive the transmission wheel 1110 to rise to a specified height, so that the groove 2 1111 on the transmission wheel 1110 can be used in conjunction with the FRP pipe, and then the servo motor 1102 drives the bidirectional screw 1101 to rotate, so that the two threaded blocks 1105 are moved to the appropriate position, so that the groove wall of the groove 2 1111 on the transmission wheel 1110 can be attached to the FRP pipe, and the groove walls of the front and rear grooves 1111 are used to jointly limit the displacement of the FRP pipe, and finally the front and rear stepper motors 1108 drive the corresponding transmission wheel 1110 to rotate, thereby towing the movement of the FRP pipe.

[0036] In order to further explain the specific working principle of the traction mechanism for glass fiber reinforced plastic production of the present invention, the above-mentioned shock absorbing device 5 includes two rotating plates 504 located in the protection box 3, and the two rotating plates 504 are symmetrically rotated and connected to the bottom end of the receiving plate 4, and then the bottom ends of the front and rear rotating plates 504 are rotatably connected to the sliding blocks 501, where the bottom ends of the sliding blocks 501 are slidably connected to the bottom wall of the protection box 3, and then the separated sides of the front and rear sliding blocks 501 are fixedly connected to two resistance blocks. The front and rear side dampers 503 are fixedly connected to the inner wall of the protective box 3 on their separated sides. In addition, shock-absorbing springs 502 are wound around the periphery of the four dampers 503. It should be noted that the adjacent sides of the front and rear side shock-absorbing springs 502 are respectively fixedly connected to the corresponding sliding blocks 501, and the separated sides of the front and rear side shock-absorbing springs 502 are fixedly connected to the inner wall of the protective box 3. When the front and rear side sliding blocks 501 move toward the separated sides, the corresponding dampers 503 and shock-absorbing springs 502 will be compressed.

[0037] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the receiving plate 4 is vibrated, the receiving plate 4 will move downward, and then the rotating plates 504 on the front and rear sides will rotate toward the separated side. While the rotating plate 504 rotates, the rotating plate 504 will also push the corresponding sliding block 501 to move. When the sliding block 501 moves, it will compress the corresponding two dampers 503 and the shock-absorbing spring 502, and use the shock-absorbing function of the shock-absorbing spring 502 and the damper 503 to reduce the vibration on the receiving plate 4.

[0038] Finally, it should be emphasized that, due to the provision of the shock-absorbing device 5 and the provision of a hydraulic telescopic rod 1106 with a shock-absorbing function under the fixed plate 1107, the vibration of the FRP pipe during traction is reduced. In addition, the groove 10 on the rubber wheel 9 and the groove 2 1111 on the two transmission wheels 1110 jointly reduce the movement of the FRP pipe during displacement. In other words, the device can ensure the stability of the FRP pipe during traction and will not cause the FRP pipe to fall off.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
