Description

Technical Field

[0001] The utility model relates to the technical field of power facilities, in particular to a cutting device for MPP power pipes. Background Art

[0002] MPP power pipes use modified polypropylene as the main raw material. They are resistant to high temperatures and external pressures and are suitable for medium and low voltage transmission line cable conduits below 10KV. MPP power pipes often need to be cut during production, transportation and use.

[0003] The MPP power pipe will be fixed in a specific cutting device to complete the cutting operation. For example, a cutting device for MPP power pipes with publication number CN213195870U includes a base, fixed plates are installed on both ends of the top of the base, swivels are sleeved on the fixed plates, a clamping mechanism is installed in the inner cavity of the swivel, a driving mechanism is installed between the outer wall of the swivel and the base, a bracket is installed in the middle of the top surface of the base, a hydraulic rod is installed on the top plate of the bracket, and the push rod of the hydraulic rod passes through the top plate of the bracket and is connected to the U-shaped seat.

[0004] This cutting device secures the power pipe inside the rotating ring and then secures it with a mounting ring. Bolts secure the mounting ring to the rotating ring. This means that after the power pipe is cut, if continuous cutting is required, the bolts must be manually removed and released, and then the pipe must be moved to the designated cutting position and re-secured. This adds numerous steps to the continuous cutting process, making this device difficult to implement on continuously cut power pipes. Summary of the Invention

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4 As shown, the present invention is a cutting device for MPP power pipes. It comprises a base plate 1, with side plates 2 fixedly connected to its top surface on either side. The two side plates 2 are arranged in a vertical direction. Both side plates 2 have through-holes 21 formed through their surfaces, with the through-holes 21 on both sides located on the same horizontal line. A rotating sleeve 22 is rotatably mounted within the through-holes 21 of the side plates 2. The inner ring of the rotating sleeve 22 is provided with a plurality of alignment grooves 23, arranged in a circumferential array equidistant from the center of the inner ring. A fixing collar 25 is removably mounted on the same side of the two rotating sleeves 22. A plurality of elastic rods 26 are fixedly connected to one side of the fixing collar 25. The shape, number, and position of the elastic rods 26 correspond to the alignment grooves 23. The fixing collar 25 is positioned and connected by inserting the elastic rods 26 into the alignment grooves 23. The MPP power pipe to be cut is then passed through the two fixing collars 25. A reinforcement ring 28 is fitted around the surface of the pipe during the removal process. The power pipe contacts several elastic rods 26, each with a positioning groove 27 on its outer surface. These grooves 27 lie in the same vertical plane. A reinforcement ring 28 slides into these grooves to reinforce the power pipe. While the inner ring of the reinforcement ring 28 is smaller than the rod's inner ring, the elastic rods 26 possess inherent elasticity, allowing them to temporarily deform and enter the grooves. This allows the rods 26 to tilt toward the central axis, thereby tightly squeezing the surface of the power pipe and securing it.

[0027] The top surface of the base plate 1 is provided with a cutting structure 3. The mounting bracket 31 of the cutting structure 3 is fixedly connected to the top surface of the base plate 1. The top surface of the mounting bracket 31 is fixedly connected to a cylinder 32, and the output end of the cylinder 32 is arranged vertically downward. The output end of the cylinder 32 is fixedly connected to a connecting seat 34. The top surface of the connecting seat 34 is fixedly connected to two vertical limiting rods 33. The top ends of the limiting rods 33 extend upward above the mounting bracket 31, and the mounting bracket 31 and the limiting rods 33 are connected in a slidable limiting connection. The bottom surface of the connecting seat 34 is provided with a slot, and a cutter 35 is rotatably disposed in the slot. The outer surface of the connecting seat 34 is fixedly connected to a transmission motor 36, and the output end of the transmission motor 36 is fixedly connected to the rotating shaft of the cutter 35.

[0028] A handwheel 11 is rotatably connected to the adjacent side surface of the side plate 2 provided on the base plate 1. An active rod 12 is rotatably provided inside the base plate 1 and is fixedly connected to the handwheel 11. A driving bevel gear 13 is sleeved on the surface of the active rod 12. A driven rod 15 is rotatably provided inside the base plate 1. The driven rod 15 and the active rod 12 are arranged perpendicularly to each other. A driven bevel gear 14 is sleeved on the surface of the driven rod 15, and the driving bevel gear 13 and the driven bevel gear 14 are meshed. Transmission gears 16 are fixedly connected to the surfaces of both ends of the driven rod 15; the transmission gears 16 are located directly below the rotating sleeves 22. A transmission gear ring 24 is fixedly connected to the circumferential surface of each rotating sleeve 22, and the surface of the transmission gear ring 24 meshes with the transmission gear 16.

[0029] When using this MPP power pipe cutting device, a fixing collar 25 is installed on the same side of both side panels 2. The MPP power pipe is then passed through the inner ring of one fixing collar 25. As it exits, a reinforcement collar 28 is placed over the surface of the pipe. The reinforcement collar 28 moves into the positioning groove 27 on the surface of the elastic rod 26. Due to the small radius of the reinforcement collar 28 and the elasticity of the elastic rod 26, the reinforcement collar 28 causes the elastic rod 26 to tilt toward the axis of rotation, resulting in close contact and fixation of the MPP power pipe surface. The two side panels 2 are reinforced in this manner. The cutting device then lowers the cutter blade 35 to cut the pipe arm. During the cutting process, the handwheel 11 is rotated, indirectly driving the driven shaft via the driving shaft. The driven shaft, via the transmission gears 16 at each end, drives the rotating sleeves 22 within the upper two side panels 2. The rotating sleeves 22 on both sides rotate the fixed power pipe, rotating the pipe until it is completely cut. After cutting is complete, the reinforcement ring 28 is removed, releasing the pressure exerted by the elastic rods 26 on the power tube surface. The power tube can then be moved in the same direction, positioning the subsequent cutting position below the cutter 35. The elastic rods 26, oriented in the same direction, facilitate movement and installation of the power tube. The easily removable reinforcement ring 28 facilitates both securing and moving the power tube, facilitating continuous cutting.

[0030] Working principle of the present invention: The present invention is a cutting device for MPP power pipes, which is provided with a fixing ring 25 and an elastic rod 26. The elastic rods 26 of the two fixing rings 25 are arranged in the same direction, so that when the power pipe moves inside, it can directly enter from the inside of the fixing ring 25 where the elastic rod 26 is not provided, so that the power pipe after cutting can be quickly installed and fixed; by providing a reinforcement ring 28, the elastic rod 26 will extend from the inside of the through hole 21, and the surface of the extended elastic rod 26 provides an installation space for the reinforcement ring 28. The reinforcement ring 28 is sleeved on the elastic rod 26, so that the elastic rod 26 is deformed to squeeze and fix the surface of the power pipe; when disassembling, the reinforcement ring 28 overcomes the elastic force of the elastic rod 26 and is quickly removed from the surface to release the fixation of the power pipe.

[0031] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
