Description

Technical Field

[0001] The present invention relates to the technical field of MPP pipes, and in particular to a pipe cooling device with a temperature monitoring function for MPP pipe production. Background Art

[0002] MPP pipe, also known as MPP power cable protection pipe, is made primarily of modified polypropylene and is widely used in municipal, telecommunications, electricity, gas, water, and heat pipeline projects, as well as in urban and rural trenchless horizontal directional drilling (HDD) power pipe construction and open-cut power pipe construction. The production process for MPP pipe requires cooling to finalize the pipe's shape. Current MPP pipe cooling devices are unable to detect the pipe's temperature and determine whether it has been adequately cooled. Furthermore, current MPP pipe cooling devices are unable to provide secondary cooling if the pipe is not sufficiently cooled, potentially failing to achieve the desired cooling effect.

Therefore, they should not be understood as limiting the present invention.

[0056] Example:

[0057] This embodiment is used for cooling and forming MPP pipes on a production line.

[0058] like Figure 1-4 As shown, a pipe cooling device for MPP pipe production with a temperature monitoring function includes a water storage tank 1, an installation box 2, a shifting mechanism 3, a pipe axis fixing mechanism 4, a water spray cooling mechanism 5, a water supply control mechanism 6, an air blowing cooling mechanism 7, an automatic water pumping mechanism 8, a temperature sensor 9, and a control terminal 10. The bottom of the installation box 2 is connected to the top of the water storage tank 1 and is fixedly installed above the water storage tank 1.

[0059] like Figure 1-3 and Figure 5-6 As shown, there are two shifting mechanisms 3, which are installed at the inlet and outlet positions at both ends of the installation box 2. The shifting mechanism 3 includes a migration device, a mounting bracket 305, a rotating motor 306 and a transmission component 307; the top of the mounting bracket 305 is a cross plate, and the front and rear end points of the cross plate are respectively fixedly mounted with migration device mounting plates, on which the migration devices are mounted, and the two migration devices are parallel and corresponding; the left and right end points of the cross plate are respectively fixedly mounted with drive device connecting frames, on which the rotating motor 306 and the transmission component 307 are mounted, and the two drive device connecting frames are respectively located on the left and right sides of the MPP tube 11 and do not contact the MPP tube 11; the cross plate is horizontally fixedly mounted on the installation box 2;

[0060] Each set of migration devices includes a shift gear 301, a rocking arm 302, a return spring 303 and a roller 304; each set of migration devices has two shift gears 301, the axes of the two shift gears 301 are horizontally collinear and rotatably mounted on the migration device mounting plate and meshed with each other; a rocking arm 302 is fixedly mounted radially on each shift gear 301, and the two rocking arms 302 are axially symmetrical with the midline of the axis connecting the two shift gears 301 as the axis, and the two rocking arms 302 are horizontally spaced apart. A return spring 303 is provided, the two ends of which are fixedly mounted on the two rocking arms 302. The return spring 303 is a tension spring. A roller 304 is rotatably mounted on the lower end of each rocking arm 302. The outer surface of each roller 304 is a friction surface. The two rollers 304 of each set of migration devices are of the same height and parallel. When the two rocking arms 302 are vertical, the distance between the two rollers 304 is smaller than the outer diameter of the MPP tube 11, and the MPP tube 11 is clamped between the two rollers 304.

[0061] The transmission assembly 307 includes a transmission wheel 3071 and a transmission belt 3072. There are four transmission wheels 3071. The output end of the rotating motor 306 is coaxially fixedly connected to the first transmission wheel 3071. The second transmission wheel 3071 and the third transmission wheel 3071 are coaxially fixedly installed on the two rollers 304 on the same side of the rotating motor 306. The fourth transmission wheel 3071 is rotatably mounted on the drive device connecting frame and is located on the inner side of the first transmission wheel 3071. The four transmission wheels 3071 are located in the same horizontal plane and are transmission-connected by the transmission belt 3072. The rotating motor 306 and the transmission wheel 3071 connected thereto are both slidably mounted on the drive device connecting frame and connected to the end of the drive device connecting frame away from the MPP tube 11 via a second return spring. The second return spring is a tension spring. When the two rocking arms 302 are in a vertical state, the second return spring is in a tension state.

[0062] When the MPP tube 11 begins to be cooled and formed, the MPP tube 11 enters between the two rollers 304, the two rollers 304 move away from each other, the two shift gears 301 rotate, and the two rocking arms 302 rotate outwards. The return spring 1 303 is stretched, and the transmission belt 1 3072 moves with the change of the position of the roller 304. The return spring 2 retracts, and the transmission belt 1 3072 remains in a taut state. The rotating motor 1 306 is started, and the transmission belt 1 3072 drives the four transmission wheels 1 3071 to rotate synchronously, and then drives the two rollers 304 on the same side to rotate synchronously. Since the outer side of the roller 304 is a friction surface, the rotation of the roller 304 will drive the MPP tube 11 to move in the horizontal direction. When the MPP tube 11 is separated from the roller 304, the return spring 1 303 retracts, pulling the two rocking arms 302 back to a vertical state. The return spring 2 is stretched, and the rotating motor 1 306 returns to its initial position.

The drive ring 407 is provided with gear teeth at positions corresponding to the drive gears 403, and the gear teeth mesh with the corresponding drive gears 403. The drive motor 402 is mounted on the fixed bracket 401, and its output end is coaxially fixedly connected to one of the drive gears 403.

[0064] Start the drive motor 402, which drives the drive gear 403 connected thereto to rotate. The drive gear 403 drives the drive ring 407 to rotate, and the drive ring 407 drives the other three drive gears 403 to rotate. The four drive gears 403 rotate synchronously, driving the four drive racks 404 to move synchronously in the radial direction, and then driving the four fixed plates 405 to move synchronously to accommodate MPP tubes 11 with different outer diameters.
