Description

Technical Field

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

[0002] During electric power construction, construction pipes include cable protection pipes, steel pipes or aluminum pipes, etc. The cable protection pipes are products with hot-dip plastic coating of PE (modified polyethylene) or internal and external coating of epoxy resin, which have excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation, and can achieve the purpose of long-term use.

[0003] Before the pipes are used, they need to be cut according to the specific situation of the construction environment to facilitate the laying work. Most of the existing cutting equipment is single-way one-time shearing, and the pipes are cut by extrusion with a blade. This cutting method is likely to cause the deformation of the cross-section of the cable protection pipes, making them change from circular to elliptical, so that they cannot be connected to the rest of the pipes or adapters. Workers also need to manually restore the cross-section to a circular shape, which affects the work efficiency. When cutting steel pipes or aluminum pipes, flying sparks will be generated. At high temperatures, the flying sparks are easily melted on the surface of the pipes, which will affect the subsequent assembly and use quality of the pipes. At the same time, the flying sparks will pose a hazard to workers and there are safety hazards. Summary of the Utility Model

[0027] The present utility model will be further described in detail below in combination with the full text.

[0028] Combined with the attached Figures 1-4 As shown, a cutting device for power construction pipes includes a workbench 1. A through hole 101 is opened on the workbench 1. A rotatable cutting blade 2 is installed in the through hole 101. A driving motor is installed on one side of the workbench 1. The output end of the driving motor is connected to the cutting blade 2 through a connecting shaft. A protective shell 8 for protecting the driving motor is installed on the workbench 1. The driving motor is fixed under the workbench 1 through a motor bracket. When the driving motor works, it drives the cutting blade 2 outside the connecting shaft to rotate and cut. The cutting blade 2 rotates in the through hole 101. When the pipe touches the cutting blade 2, the cutting of the pipe is completed.

[0029] When the present utility model is specifically implemented, such as Figure 1 and Figure 3As shown in the figure, a rotary cutting device 3 for driving the pipe to rotate is installed on the workbench 1. The rotary cutting device 3 includes a connecting block 301 and a rotating shaft 302 oppositely arranged on the workbench 1. A rotating hole 303 is formed in the connecting block 301. The rotating shaft 302 and the inner wall of the rotating hole 303 are connected by a torsion spring. Specifically, one end of the torsion spring is connected to the outer side wall of the rotating shaft 302, and the other end of the torsion spring is connected to the inner wall of the rotating hole 303. When the connecting plate 304 drives the rotating shaft 302 to rotate, the torsion spring works and can drive the connecting plate 304 to reset through the reset of the torsion spring. A connecting plate 304 is installed on the rotating shaft 302. One side of the connecting plate 304 is hinged with a first limiting plate 305 and a second limiting plate 306 for installing the pipe. A cutting groove 5 for cutting is formed in the connecting plate 304. The first limiting plate 305 and the second limiting plate 306 are hinged on the connecting plate 304 and are respectively located on both sides of the cutting groove 5. A screw rod 9 is installed on the connecting plate 304. Installation grooves 10 for cooperating with the screw rod 9 are formed in the first limiting plate 305 and the second limiting plate 306, and the screw rod 9 is fixedly connected through a nut. A handle 13 is installed on the outer side of the second limiting plate 306. The pipe is placed between the first limiting plate 305, the second limiting plate 306 and the connecting plate 304 and is fixedly connected through the screw rod 9 and the nut. Then, the handle 13 drives the connecting plate 304 to rotate under the action of the rotating shaft 302, and the torsion spring works. When the pipe approaches the cutting blade 2, the cutting blade 2 cuts the pipe.

[0030] When the present utility model is specifically implemented, as Figure 3 shown. A protective plate 4 is slidably installed on one side of the rotary cutting device 3. A guide rail 6 is installed between the two connecting blocks 301. A guide hole 7 for cooperating with the guide rail 6 is formed in the protective plate 4. The protective plate 4 is of an arc-shaped structure. When cutting is required, the protective plate 4 is moved to one side of the cutting groove 5 through the guide rail 6. Specifically, the guide rail 6 and the guide rail 6 are of a non-circular structure.

[0031] A debris box 11 is installed inside the workbench 1 and below the cutting blade 2.

[0032] Limit plates 12 are installed at both ends of the connecting plate 304. When the connecting plate 304 rotates under the action of the rotating shaft 302 and the pipe approaches the cutting blade 2, the cutting blade 2 cuts the pipe. The maximum rotation angle of the connecting plate 304 is close to the upper end surface of the workbench 1, and the limit plate 12 will abut against the upper end surface of the workbench 1 to complete the limit. At this time, the cutting blade 2 completely cuts the pipe.

[0033] Embodiment 1:

[0034] When cutting the cable protection pipe, place the cable protection pipe between the first limit plate 305, the second limit plate 306 and the connecting plate 304, and fixedly connect them through the screw 9 and the nut. Then, drive the connecting plate 304 to rotate under the action of the rotating shaft 302 through the handle 13. The torsion spring works, and the driving motor works to drive the cutting blade 2 outside the connecting shaft to rotate and cut. The cutting blade 2 rotates in the through hole 101. When the cable protection pipe touches the cutting blade 2, the cutting of the pipe fitting is completed. The worker withdraws the force on the handle 13, and the torsion spring resets, driving the connecting plate 304 and the cable protection pipe to reset. By removing the bolts on the first limit plate 305 and the second limit plate 306, the disassembly is completed.

[0035] Embodiment 2:

[0036] As Figure 4 shown, when cutting a steel pipe or an aluminum pipe, place the steel pipe or the aluminum pipe between the first limit plate 305, the second limit plate 306 and the connecting plate 304, and fixedly connect them through the screw 9 and the nut. Move the protection plate 4 to one side of the cutting groove 5 through the guide rail 6 for protection. Drive the connecting plate 304 to rotate under the action of the rotating shaft 302 through the handle 13. The torsion spring works, and the driving motor works to drive the cutting blade 2 outside the connecting shaft to rotate and cut. The cutting blade 2 rotates in the through hole 101. When the steel pipe or the aluminum pipe touches the cutting blade 2, the cutting of the pipe fitting is completed.

[0037] The worker withdraws the force on the handle 13, and the torsion spring resets, driving the connecting plate 304 and the cable protection pipe to reset. Move the protection plate 4. By removing the bolts on the first limit plate 305 and the second limit plate 306, the disassembly is completed. When cutting the steel pipe or the aluminum pipe, debris will be generated, and the debris will fall into the debris box 11, which is convenient for storage.

[0038] The above describes the present invention and its embodiments. Such description is not restrictive. What is shown throughout the text is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative concept of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall all fall within the protection scope of the present invention.
