Description

Technical Field

[0001] This invention relates to the field of power pipe cutting technology, specifically to a power pipe cutting device for power construction. Background Technology

[0002] Electrical conduits are products made by hot-dip plastic coating of PE 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, will not cause electrolytic corrosion, low water absorption, high mechanical strength, and low coefficient of friction, which can achieve the purpose of long-term use and effectively prevent damage from plant roots and soil environmental stress.

[0003] When power pipes are put into construction, they need to be cut into different lengths for easy assembly and installation. However, the power pipe cutting devices currently on the market are cumbersome to operate and can no longer meet the needs of daily construction. When cutting, the power pipe is usually pressed and fixed by an arm. This fixing method is prone to deviation during cutting. Therefore, it is necessary to develop a power pipe cutting device for use in the existing power construction technology field. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a power pipe cutting device for power construction, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power pipe cutting device for power construction, comprising a device body, the device body including a base plate set on the ground, and auxiliary support plates for auxiliary support distributed on both sides of the base plate, a cutting frame installed at the top of the base plate, and a cavity opened inside the cutting frame, an electric guide rail installed in the cavity, and a slider adapted to the electric guide rail slidably installed on the outer wall of the electric guide rail, a hydraulic rod installed on the outer wall of the slider facing inward, and a cutting disc for cutting power pipes installed at the end of the hydraulic rod, a feeding and driving assembly installed on one side of the cutting frame at the top of the base plate to assist the feeding of power pipes, and a limiting assembly installed on the other side of the cutting frame at the top of the base plate for measuring and limiting the length of the power pipes.

[0006] By adopting the above technical solution, the feeding length of the power tube can be measured using a measuring tape. Once the length meets the standard, feeding can be stopped. At this time, the limiting component will automatically start to limit and fix the power tube, replacing the manual clamping method, improving the stability during cutting and thus improving the quality. In addition, this device can automatically limit and fix, saving manpower, improving the automation of the device, and thus achieving the effect of improving production efficiency.

[0008] By adopting the above technical solution, the power tube can be assisted in feeding, and the movement of the power tube can be used to drive the drive components, thereby providing power for the limit control components and the cleaning components.

[0009] The present invention is further configured such that the limiting component includes a limiting frame fixed to the top of the base plate, and a driven plate is provided at one end of the limiting frame. A multi-stage telescopic rod installed in the inner wall of the limiting frame is connected to the inner end face of the driven plate. A measuring tape with its end fixed to the inner end face of the driven plate is also installed in the inner wall of the limiting frame. A rubber pad for limiting and fixing the force tube is provided inside the limiting frame. An adjusting bolt is connected to the top of the rubber pad through a bearing. A sleeve rod is vertically sliding and horizontally limiting connected inside the adjusting bolt. A nut is fixedly provided at the top of the sleeve rod.

[0010] By adopting the above technical solution, the length of the power pipe can be measured and the pipe can be limited after the length is fixed.

[0011] The present invention is further configured such that a cleaning component is installed on one side of the feed frame, and the cleaning collar includes two sets of cleaning collars disposed at the feed frame outlet. The inner end faces of the two sets of cleaning collars are provided with a cleaning layer, and the outer end face of each set of cleaning collars is fixedly connected with a sliding rod, and the sliding rod extends into the outer wall of the mounting frame and is slidably connected to the outer wall of the mounting frame.

The end face of the seventh bevel gear is fixedly connected to a mounting shaft extending to the bottom end face of the top plate, and the mounting shaft is connected to the top plate through a spring disc.

[0014] By adopting the above technical solution, the limiting component is controlled, which facilitates the rapid positioning and retrieval of the workpiece and improves work efficiency.

[0015] In summary, the present invention has the following main beneficial effects:

[0016] 1. This invention utilizes a feeding and driving assembly, a limiting assembly, and a limiting control assembly. First, the main body of the device is fixed to the ground in the work area using bolts. Then, the power pipe to be cut is inserted into the feeding frame. Further, the power pipe is pushed, and it moves forward with the assistance of the driven wheel until its end reaches the limiting frame. The power pipe continues to move, allowing its end to push the driven plate outward. During this process, a multi-stage telescopic rod assists the driven plate's movement and limits its direction of movement. Simultaneously, a measuring tape provides the operator with the current movement value of the power pipe. Once the specified value is reached, the movement of the power pipe stops. Throughout this process, the power pipe... When the force tube moves, it drives the driven wheel to rotate. The driven wheel then drives the drive turntable to rotate through transmission. The drive turntable then drives the sixth bevel gear to rotate through transmission. The sixth bevel gear then drives the seventh bevel gear to rotate through meshing. The seventh bevel gear then drives the nut to rotate. The nut then drives the adjusting bolt to rotate through the sleeve rod. The adjusting bolt then pulls the rubber pad upward. When the driven wheel stops rotating, the seventh bevel gear will rotate in the opposite direction to reset under the reset action of the clockwork disc. The reverse rotation of the seventh bevel gear will drive the nut to rotate in the opposite direction. At this time, the nut will cause the adjusting bolt to move downward and push the lower base frame to squeeze the power tube, thus achieving the effect of limiting and fixing the power tube.

[0017] 2. This invention, through a feeding and driving assembly and a cleaning assembly, enables the driven wheel to rotate. When the driven wheel rotates, it drives the first bevel gear to rotate via transmission. The first bevel gear then drives the second bevel gear to rotate via meshing. The second bevel gear then drives a set of driving gears to rotate via a drive shaft. This set of driving gears acts on the driven gear ring, causing it to rotate. The driven gear ring then drives the cleaning sleeve to rotate on the outer wall of the power pipe, thereby cleaning the outer wall of the power pipe through its inner cleaning layer. Furthermore, the rotation of this set of driving gears drives the third bevel gear to rotate via a synchronous shaft. The third bevel gear then drives the fifth bevel gear to rotate in the opposite direction via a fourth bevel gear. The fifth bevel gear then drives the second set of driving gears to rotate in the opposite direction via a second set of synchronous shafts. The second set of driving gears then drives the second set of cleaning sleeves to rotate in the opposite direction, thereby achieving a reverse secondary cleaning of the outer wall of the power pipe and further improving the cleaning effect.

[0028] The embodiments of the present invention will now be described.

[0029] A power pipe cutting device for power construction, such as Figure 1-8 As shown, the device includes a main body 1, which includes a base plate 101 set on the ground.

[0030] Please see Figure 1 as well as Figure 3-4 A feeding and driving assembly 2 is installed on one side of the cutting frame 103 at the top of the base plate 101 to assist in the feeding of the power tube.

[0031] Specifically, the feeding and driving assembly 2 includes a feeding frame 201 fixed to the top of the base plate 101, and a driven wheel 202 rotatably connected to the inner wall of the feeding frame 201 is installed inside the feeding frame 201. A mounting frame is provided above one side of the driven wheel 202, and a first bevel gear 203, which is drively connected to the driven wheel 202, is installed inside the mounting frame. A second bevel gear 204 is meshed with one side of the first bevel gear 203, and a drive shaft 205 is fixedly connected to the outer end of the second bevel gear 204.

[0032] Please see Figure 1 as well as Figure 5-6 On the other side of the cutting frame 103, at the top of the base plate 101, a limiting component 3 is also installed for measuring the length of the power pipe and limiting and fixing it.

[0033] Specifically, the limiting component 3 includes a limiting frame 301 fixed to the top of the base plate 101, and a driven plate 302 is provided on one side end of the limiting frame 301. A multi-stage telescopic rod 304 installed in the inner wall of the limiting frame 301 is connected to the inner end face of the driven plate 302. A measuring tape 303 with its end fixed to the inner end face of the driven plate 302 is also installed in the inner wall of the limiting frame 301. A rubber pad 305 for limiting and fixing the force tube is provided inside the limiting frame 301. An adjusting bolt 306 is connected to the top of the rubber pad 305 through a bearing. A sleeve rod 307 is connected to the adjusting bolt 306 for vertical sliding and horizontal limiting. A nut 308 is fixedly provided at the top of the sleeve rod 307.

[0034] Please see Figure 3-4 A cleaning component 4 is installed on one side of the feed frame 201 to clean the outer wall of the power pipe;

[0035] Specifically, the cleaning collar 401 includes two sets of cleaning collars 401 disposed at the outlet of the feed frame 201. The inner end face of both sets of cleaning collars 401 is provided with a cleaning layer 402, and the outer end face of each set of cleaning collars 401 is fixedly connected with a slide rod 403. The slide rod 403 extends into the outer wall of the mounting frame and is slidably connected to the outer wall of the mounting frame. The outer end face of the cleaning collar 401 located inside the slide rod 403 is also provided with a driven gear ring 404 that can be driven by the drive gear 206.

[0036] Please see Figure 7-8 A limit control component 5 is provided between the feeding frame 201 and the limit frame 301. The position of the rubber pad 305 in the limit frame 301 is controlled by the running state of the driven wheel 202, which is conducive to quick picking and positioning of the power tube.

[0037] Specifically, the limit control component 5 includes a drive turntable 501 that is connected to the driven wheel 202. The drive turntable 501 is connected to a sixth bevel gear 502 via a one-way bearing, a drive turntable, and a drive belt. The bottom end of the sixth bevel gear 502 is meshed with a seventh bevel gear 503. The seventh bevel gear 503 is fixedly connected to the top end of the nut 308 to drive the nut 308 to rotate. A top plate 504 is provided above the seventh bevel gear 503. The top plate 504 is mounted on the top end of the limit frame 301 via a support column. The end face of the seventh bevel gear 503 is fixedly connected to a mounting shaft 505 that extends to the bottom end face of the top plate 504. The mounting shaft 505 is connected to the top plate 504 via a spring disc.

[0038] The working principle of this invention is as follows: First, the main body 1 of the device is fixedly installed on the ground of the work area by bolts. Then, the power pipe to be cut can be inserted into the feed frame 201.

[0039] Furthermore, the power pipe is pushed, and the power pipe will move forward with the assistance of the driven wheel 202 until the end of the power pipe moves into the limit frame 301. Then the power pipe continues to move, so that the end of the power pipe can push the driven plate 302 to move outward. During this process, the multi-stage telescopic rod 304 will assist the movement of the driven plate 302 and limit its movement direction. At the same time, the measuring tape 303 will provide the operator with the current value of the power pipe movement, and then stop moving the power pipe after reaching the specified value.

[0040] In the above process, when the power pipe moves, it will drive the driven wheel 202 to rotate. After the driven wheel 202 rotates, it will drive the drive turntable 501 to rotate through the transmission action. After the drive turntable 501 rotates, it will drive the sixth bevel gear 502 to rotate through the transmission action. After the sixth bevel gear 502 rotates, it will cause the seventh bevel gear 503 to rotate through the meshing action. After the seventh bevel gear 503 rotates, it will drive the nut 308 to rotate. After the nut 308 rotates, it will drive the adjusting bolt 306 to rotate through the sleeve rod 307. After the adjusting bolt 306 rotates, it will pull the rubber pad 305 to move upward.

[0041] When the driven wheel 202 stops rotating, the seventh bevel gear 503 will rotate in the opposite direction to reset under the reset action of the spring disc. After the seventh bevel gear 503 rotates in the opposite direction, it will drive the nut 308 to rotate in the opposite direction. At this time, the nut 308 will cause the adjusting bolt 306 to move downward and push the rubber pad 305 to squeeze the power tube, thereby achieving the effect of limiting and fixing the power tube.

[0042] Furthermore, when the driven wheel 202 rotates, it will also drive the first bevel gear 203 to rotate through the transmission action. After the first bevel gear 203 rotates, it will drive the second bevel gear 204 to rotate through the meshing action. After the second bevel gear 204 rotates, it will drive a set of drive gears 206 to rotate through the drive shaft 205. After the set of drive gears 206 rotates, it will act on the driven gear ring 404, causing the driven gear ring 404 to rotate. After the driven gear ring 404 rotates, it will drive the cleaning collar 401 to rotate on the outer wall of the power pipe, thereby cleaning the outer wall of the power pipe through the cleaning layer 402 on its inner side.

[0043] Furthermore, after the drive gear 206 rotates, it drives the third bevel gear 208 to rotate via the synchronous shaft 207. The third bevel gear 208 then drives the fifth bevel gear 210 to rotate in the opposite direction via the fourth bevel gear 209. After the fifth bevel gear 210 rotates in the opposite direction, it drives the second set of drive gears 206 to rotate in the opposite direction. At this time, the second set of cleaning collars 401 rotates in the opposite direction, thereby achieving reverse secondary cleaning of the outer wall of the power pipe, further improving the cleaning effect.

[0044] Finally, the cutting disc 107 is activated to cut the power pipe. Under the action of the hydraulic rod 106, the cutting disc 107 will cut through the inner wall of the power pipe. Then, the electric guide rail 104 is run. At this time, the slider 105 will drive the cutting disc 107 to rotate and cut on the outer wall of the power pipe, thereby completing the cutting operation of the power pipe.
