Description

Technical Field

[0001] This utility model relates to the field of flaring device technology, specifically a flaring device for double-wall corrugated pipes. Background Technology

[0002] Existing double-wall corrugated pipes are a new type of lightweight pipe made of high-density polyethylene. They are characterized by light weight, high pressure resistance, good toughness, fast construction, and long service life. Their excellent pipe wall structure design significantly reduces costs compared to other pipe structures, leading to their widespread use both domestically and internationally, and their large-scale replacement of concrete and cast iron pipes. For example, patent CN220390308U discloses a double-wall corrugated pipe flaring machine, which includes a working box. A reduction motor is fixed to the upper end of the working box. The output end of the reduction motor passes through the upper end of the working box and is fixedly connected to a disc. A fixing block is fixedly connected to the lower end of the disc, and a groove is formed on the lower end of the fixing block. The device drives a threaded rod to rotate via a drive motor, a first helical gear, and a second helical gear. The threaded rod, threaded sleeve, connecting block, and arc-shaped block drive two flaring blocks to move relative to each other. Then, a reduction motor, a disc, and a cylinder drive the flaring blocks to rotate, and the flaring blocks flare the socket of the double-wall corrugated pipe body again. This process is repeated multiple times, thus automatically flaring the socket of the double-wall corrugated pipe body without requiring manual rotation of the double-wall corrugated pipe. However, since double-wall corrugated pipes are usually quite rigid, direct flaring can easily damage them, and the flaring process is difficult, resulting in low flaring efficiency.

[0003] Therefore, this utility model provides a double-wall corrugated pipe flaring device. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a double-walled corrugated pipe flaring device to solve the problems mentioned in the background art. This invention can simultaneously heat both the inner and outer sides of the double-walled corrugated pipe, thereby softening the pipe, preventing damage during flaring, and improving flaring efficiency. The double-walled corrugated pipe can be fixed by a clamping structure, and flaring can be performed by rotating the flaring rod.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a double-wall corrugated pipe flaring device, comprising a support frame, a fixing frame mounted on the support frame, a double-wall corrugated pipe installed inside the fixing frame, a clamping structure installed inside the fixing frame, a fixing ring fixed on one side of the fixing frame, a heating tube installed inside the fixing ring, a sliding plate slidably fitted on the support frame, a driving structure fixed on the sliding plate, a telescopic rod fixed at the output end of the driving structure, a flaring rod fixed at one end of the telescopic rod, a piston rod slidably fitted inside the flaring rod, and a flaring plate installed at one end of the piston rod.

[0006] Furthermore, the clamping structure includes multiple clamping plates, and multiple elastic telescopic rods are fixed between the clamping plates and the fixing frame, with a double-walled corrugated pipe located between the multiple clamping plates.

[0007] Furthermore, a fixing plate is fixed on the support frame, and an electric cylinder is fixed on the fixing plate. The output end of the electric cylinder is fixedly connected to the sliding plate.

[0008] Furthermore, the drive structure includes a motor and a reducer, both of which are fixedly connected to the slide plate.

[0009] Furthermore, the output end of the motor is fixedly connected to the input end of the reducer, and the output end of the reducer is fixedly connected to the telescopic rod.

[0010] Furthermore, both the telescopic rod and the expanding rod are hollow structures, and the piston rod is made of a heat-conducting material.

[0011] Furthermore, a locking block is fixed to one end of the piston rod, and the locking block corresponds to the expansion plate.

[0012] Furthermore, one end of the telescopic rod is rotatably fitted with an air inlet head, and there is a gap between the air inlet head and the telescopic rod. The telescopic rod has multiple air inlets, which are connected to the gap.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a double-wall corrugated pipe flaring device, which includes a fixing frame; a fixing ring; a heating tube; a flaring rod; a piston rod; a double-wall corrugated pipe; and a clamping structure.

[0014] A fixing ring is installed on one side of the fixing frame, and a heating tube is installed inside the fixing ring. A piston rod is slidably installed inside the reaming rod, which allows hot gas to be introduced into the reaming rod, thereby simultaneously heating both the inner and outer sides of the double-walled corrugated pipe. This softens the double-walled corrugated pipe, prevents damage during reaming, and improves reaming efficiency. A clamping structure is installed inside the fixing frame to fix the double-walled corrugated pipe, and reaming is performed by rotating the reaming rod. Attached Figure Description

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a double-wall corrugated pipe flaring device, including a support frame 1, a fixing frame 2 mounted on the support frame 1, a double-wall corrugated pipe 5 installed inside the fixing frame 2, a clamping structure installed inside the fixing frame 2, a fixing ring 6 fixed on one side of the fixing frame 2, a heating tube 7 installed inside the fixing ring 6, a sliding plate 8 slidably fitted on the support frame 1, a driving structure fixed on the sliding plate 8, a telescopic rod 13 fixed at the output end of the driving structure, a flaring rod 14 fixed at one end of the telescopic rod 13, a piston rod 15 slidably fitted inside the flaring rod 14, and a flaring plate 17 installed at one end of the piston rod 15.

[0022] In this embodiment, the clamping structure includes multiple clamping plates 3, and multiple elastic telescopic rods 4 are fixed between the clamping plates 3 and the fixing frame 2. The double-walled corrugated pipe 5 is located between the multiple clamping plates 3.

[0023] Specifically, the double-wall corrugated pipe 5 is passed through the clamping plate 3, and the clamping plate 3 is moved by the elastic telescopic rod 4 to clamp and fix the double-wall corrugated pipe 5, thereby facilitating the enlargement of the hole of the double-wall corrugated pipe 5.

[0024] A fixing plate 9 is fixed on the support frame 1, and an electric cylinder 10 is fixed on the fixing plate 9. The output end of the electric cylinder 10 is fixedly connected to the slide plate 8.

[0025] Specifically, the electric cylinder 10 can push the slide plate 8 to slide, thereby pushing the drive structure and the reaming rod 14 to slide, thus reaming the hole. The depth of reaming can be selected according to the requirements.

[0026] The drive structure includes a motor 11 and a reducer 12. Both the motor 11 and the reducer 12 are fixedly connected to the slide plate 8. The output end of the motor 11 is fixedly connected to the input end of the reducer 12. The output end of the reducer 12 is fixedly connected to the telescopic rod 13. The telescopic rod 13 and the expanding rod 14 are both hollow structures. The piston rod 15 is made of heat-conducting material. One end of the piston rod 15 is fixed with a locking block 18, which corresponds to the expanding plate 17. One end of the telescopic rod 13 is rotatably fitted with an air inlet head 16. There is a gap between the air inlet head 16 and the telescopic rod 13. Multiple air inlets are opened on the telescopic rod 13, and the air inlets are connected to the gap.

[0027] Specifically, when expanding the hole, the heating tube 7 is energized, which heats the double-walled corrugated pipe 5, softening it and facilitating expansion. Then, the motor 11 is started, causing the telescopic rod 13 to rotate, which in turn rotates the expanding rod 14. At the same time, hot air is introduced into the air inlet 16, which pushes the piston rod 15 upward to expand the hole. The hot air also heats the piston rod 15. After heat conduction through the piston rod 15 and the expanding plate 17, both the inside and outside of the double-walled corrugated pipe 5 are heated simultaneously, ensuring a softening effect, thereby reducing the difficulty of expanding the hole and improving work efficiency.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
