Description

Technical Field

[0001] The invention belongs to the field of cooling and shaping of cable protection tubes, and in particular relates to a BWFRP cable protection tube cooling and shaping device. Background Art

[0002] BWFRP cable protection tube is a composite material pipe made by mixing glass fiber and recyclable plastic particles using a special process. It can not only be used for a long time in various harsh environments, but also complies with the national environmental protection and recycling policy, effectively reducing resource waste and environmental pollution. When laying cables underground, it is often necessary to sheath a larger cable protection tube on the outside of the cable to improve the protection of the cable. In the preparation process of larger BWFRP cable protection tubes, cooling and shaping is a crucial link. The effect of cooling and shaping directly affects the dimensional accuracy, surface quality and overall performance of the pipe.

[0003] At present, when cooling and shaping the BWFRP cable protection pipe, a common and widely used method is to use the spraying method to implement the cooling and shaping operation. However, since the surface of the formed pipe just extruded from the extruder is still relatively soft, if the cooling water is directly applied to the outer surface of the pipe in a spraying manner, the impact force of the water flow and the effect of the sudden drop in temperature can easily cause depressions, ripples or other forms of surface defects on the outer surface of the pipe, affecting the surface quality of the pipe after cooling and shaping; secondly, since the sprayed cooling water directly acts on the outer surface of the pipe, while the inner wall of the pipe still has a high temperature, the existence of this internal and external temperature difference leads to uneven distribution of thermal stress in the pipe during the cooling process, affecting the final shaping effect and quality of the pipe.

[0040] In order to prevent the outer wall of the pipeline from being dented when the pipeline is cooled, the pipeline is first passed through the annular water storage jacket 504 when cooling the pipeline.

[0046] In order to cool the inner wall of the pipeline, before the circular ring 7 moves to the right, the use position of the U-shaped block 25 on the support frame 2 is adjusted according to the length of the pipeline by using the fastening bolt 27. After the position of the U-shaped block 25 is adjusted, the circular ring 7 will also drive the extrusion ring 902 to move to the right during the movement to the right. After the extrusion ring 902 moves to contact with the stopper 28, the extrusion ring 902 will be squeezed by the stopper 28. At this time, the extrusion ring 902 will squeeze the spring 2 901 and push the push plate 813 to move left. The push plate 813 moves left and drives the tooth plate 2 807 to move left. The tooth plate 2 807 moves left and drives the gear 2 806 to rotate clockwise. The rotation of the gear 2 806 drives the connecting shaft 804 to rotate. The rotation of the connecting shaft 804 drives the nozzle 805 Rotate, and then motor 809 works to drive one of the gears 802 to rotate, and the cooperation of gear ring 801 can drive the other gears 802 to rotate synchronously. During the rotation of gear 802, tooth plate 803 will also be driven to move, so that multiple tooth plates 803 are close to each other. The movement of tooth plate 803 can drive the nozzle 805 to move, to ensure that the cooling water sprayed by the nozzle 805 can enter the interior of the pipe, and the tooth plate 803 stops moving, and then the inner wall of the pipe can be cooled by the water sprayed by the nozzle 805. After the cooling of the inner wall of the pipe is completed, the ring 7 moves to the left and returns to the initial position.

[0050] In order to improve the cooling effect on the inner wall of the pipeline, in the process of spraying water on the inside of the pipeline when the pipeline is tilted, the motor 29 works to drive the connecting block 30 to rotate, and the rotation of the connecting block 30 drives the ring 31 to rotate. The rotation of the ring 31 can drive the connecting rod 32 to swing slightly back and forth, so that the conveying frame 6 can be driven to swing slightly back and forth through the rotating shaft 14, so that the inclined pipeline located on the conveying frame 6 can shake slightly, and in the process of pipeline shaking, the pipeline can be limited forward and backward by the cooperation of the limiting plate 33 and the rubber pad 34 to ensure that the cooling water sprayed from the nozzle 805 can smoothly enter the interior of the pipeline, so that in the process of cooling the inner wall of the pipeline, the cooling water entering the pipeline can flow and distribute more evenly inside the pipeline through the shaking of the pipeline, so that the temperature of each part of the pipeline is more uniform, thereby further improving the cooling effect on the inner wall of the pipeline.

[0051] See also Figure 2 Two support blocks 35 are arranged on the inner side of the fixing frame 1 and are symmetrically distributed front and back, and the upper part of the support block 35 contacts the bottom of the support frame 2. The support block 35 can stably support the support frame 2 hingedly arranged on the fixing frame 1 to ensure the stability of the support frame 2 during use.

[0052] During specific operation, first let the right end of the pipe pass through the annular water storage jacket 504. The annular water storage jacket 504 and the water tank 4 can be used to perform preliminary cooling on the pipe to prevent the pipe from being directly sprayed and causing depressions on the outside of the pipe. Then, the cooling and shaping mechanism 8 and the extrusion mechanism 9 can be used to evenly cool the outer and inner walls of the pipe to ensure uniform cooling of the pipe, thereby ensuring the effect and quality of the pipe after shaping.
