Description

Technical Field

[0001] This invention belongs to the technical field of power pipe cutting devices, and particularly relates to a construction power pipe cutting device. Background Technology

[0002] Electrical conduits are products made by hot-dip plastic coating of PE (modified polyethylene) or internal and external coating of epoxy resin, possessing excellent corrosion resistance. The coating itself also has good electrical insulation properties, preventing electrolytic corrosion. They have low water absorption, high mechanical strength, and a low coefficient of friction, enabling long-term use. They also effectively prevent damage from plant roots and soil stress. Electrical conduits need to be cut to the required length before use.

[0003] Chinese invention patent CN116690696A discloses an electrical conduit cutting device, including a housing. A circular slide is fixedly installed in the inner cavity of the housing. A circumferential slide is opened on the front surface of the circular slide. A diameter adjustment mechanism is slidably connected to the circumferential slide of the circular slide. The diameter adjustment mechanism slides in a finger-like manner on the circumferential slide of the circular slide. The diameter adjustment mechanism has a telescopic adjustment function. A cutting machine is connected below the diameter adjustment mechanism. Rectangular openings are opened on both the left and right sides of the inner cavity of the housing. Sliding mechanisms are symmetrically fixedly installed on the left and right sides of the inner cavity of the housing. A clamping mechanism is installed on the side of the sliding mechanisms that are close to each other.

[0004] However, the above-mentioned patents have the following shortcomings: 1. The above-mentioned patent can clamp the two sides of the pipe by setting two clamping mechanisms, and the positions of the two clamping mechanisms are adjustable, so that pipes of different diameters can be clamped and fixed. However, the power pipe is made of PE (modified polyethylene), and its two sides are easily deformed when squeezed and fixed. Under such circumstances, cutting the power pipe will cause the cut of the power pipe to be deformed and twisted and not flat enough, thereby reducing the cutting quality of the power pipe. 2. The above-mentioned patent can cut pipes of different diameters through the cutting platform, but its cutting machine lacks a heat dissipation mechanism when cutting pipes. As a result, the cutting blade will heat up due to friction when cutting pipes, which will cause the pipe in contact with it to melt. After the pipe cut melts and cools down, it will become uneven, which will reduce the cutting quality of the power pipe. Summary of the Invention

[0005] This invention provides a construction power pipe cutting device, which aims to solve the problems mentioned in the background art, where power pipes are made of PE (modified polyethylene), and their two sides are easily deformed when squeezed and fixed. Under such circumstances, cutting the power pipe will cause the cut to be deformed, twisted and not smooth, thereby reducing the cutting quality of the power pipe. In addition, the lack of a heat dissipation mechanism means that when cutting the pipe, the blade of the cutting machine will heat up due to friction, causing the pipe in contact with it to melt. After the pipe cut melts and cools down, it becomes uneven, thus reducing the cutting quality of the power pipe.

[0006] The present invention is implemented as follows: a construction power pipe cutting device includes a mounting frame, a through groove is provided in the middle of the mounting frame, a mounting frame is fixedly connected to one side of the mounting frame, and a fixing component is provided on the other side of the mounting frame to fix the device in pipes with different inner diameters. A first stepper motor is fixedly connected to the surface of the mounting frame. A rotating rod is fixedly connected to the output shaft of the first stepper motor. A through groove is provided in the middle of the rotating rod. A cutting component for rotating and cutting the pipe is fixedly connected to the end of the rotating rod.

[0007] Preferably, the fixing component includes a mounting box, and the number of mounting boxes is set to multiple, the sidewalls of the multiple mounting boxes are fixedly connected to the mounting frame, and the multiple mounting boxes are distributed around the center of the through groove; A rotating shaft is provided through the surface of the mounting box. The rotating shaft is rotatably connected to the mounting box. A driven gear is fixedly connected to one end of the rotating shaft, and a turntable is fixedly connected to the other end of the rotating shaft. The turntable is located inside the mounting box. An eccentric shaft is fixedly connected to the turntable side, a drive sleeve is sleeved on the outside of the eccentric shaft, an extension rod is fixedly connected to the side wall of the drive sleeve, the end of the extension rod passes through the mounting box, the extension rod is slidably connected to the mounting box, and a stop block is fixedly connected to the end of the extension rod. A transmission structure is provided between the multiple mounting boxes to simultaneously drive the rotation of multiple driven gears; When the gear rotates, it can drive the turntable to rotate through the shaft. At the same time, the turntable will drive the bias shaft on its surface to rotate. When the bias shaft rotates, it will drive the drive sleeve and the extension rod to slide relative to the mounting box, thereby adjusting the distance between the end block of the extension rod and the mounting bracket.

[0008] Preferably, the transmission structure includes a rotating cylinder and a second stepper motor. The rotating cylinder is disposed through a through groove. The outer periphery of the rotating cylinder is rotatably connected to the through groove. A driving gear ring is fixedly connected to the outer periphery of one end of the rotating cylinder, and a driven gear ring is fixedly connected to the outer periphery of the other end of the rotating cylinder. The outer periphery of the driven gear ring is meshed with multiple driven gears. The side wall of the second stepper motor is fixedly connected to the mounting frame, and the output shaft of the second stepper motor is fixedly connected to a drive gear, which meshes with a drive gear ring. By starting the second stepper motor, the active gear drives the active gear ring and the rotating cylinder to rotate. At the same time, the rotating cylinder drives multiple driven gears to rotate synchronously through the driven gear ring. By making multiple synchronous gears rotate synchronously, the positions of multiple abutments can be adjusted synchronously. This synchronous adjustment of the positions of multiple abutments causes them to abut against the inner walls of pipes of different diameters, thus fixing the device inside the pipe. Because multiple abutments surround the inner wall of the pipe for support and fixation, uneven stress on the pipe can be avoided, which can cause deformation. This also prevents the pipe from twisting during cutting due to deformation, resulting in an uneven cut.

[0009] Preferably, the cutting component includes a mounting plate, the side wall of the mounting plate is fixedly connected to the end of the rotating rod, an electric push rod is fixedly connected to the top of the mounting plate, a fixing plate is fixedly connected to the output end of the electric push rod, the fixing plate is L-shaped, a cutting machine is fixedly connected to the surface of the fixing plate, and a cooling structure for cooling the blade of the cutting machine is provided on the surface of the fixing plate. When the cutting machine cuts the inner wall of the pipe, the first step motor drives the rotating rod to rotate, which in turn drives the mounting plate to rotate synchronously. This allows the cutting machine, which is set at the end of the mounting plate, to perform a ring cut on the pipe. When it is necessary to cut ring pipes of different diameters, the fixed viewing plate can be driven by the electric push rod to adjust the position of the cutting machine, thus enabling the cutting machine to cut pipes of different diameters.

[0010] Preferably, the cooling structure includes a water storage tank, a water supply pipe on the side wall of the water storage tank, a micro water pump fixedly connected to the top of the water storage tank, an inlet pipe connected to the input end of the micro water pump, the end of the inlet pipe extending into the interior of the water storage tank, an outlet pipe connected to the output end of the micro water pump, the outlet pipe being made of soft rubber material, a nozzle connected to the end of the outlet pipe, and the nozzle penetrating through the fixed plate; When the cutting machine is cutting the pipe, the micro water pump can be started to draw cooling water from the water tank through the inlet pipe and deliver the cooling water to the nozzle through the outlet pipe. The nozzle will then spray the cooling water onto the cutting machine blade, thereby continuously cooling the blade. This prevents the cutting blade from generating high temperatures due to cutting friction, which could melt the pipe cut. This also prevents the cut end of the pipe from becoming uneven after melting and cooling. If the cooling water in the water tank is insufficient, cooling water can be added to the water tank through the replenishment pipe.

[0011] Preferably, the bottom of the mounting plate is further provided with a stabilizing structure to improve the stability of the mounting plate when rotating. The stabilizing structure includes a protective shell and a guide wheel. The rotating rod passes through the protective shell and is rotatably connected to the protective shell. The outer side of the protective shell is provided with multiple grooves that match the mounting box. The protective shell is fixedly connected to the mounting frame by bolts. A guide rail is fixedly connected to the outer periphery of the protective shell. The number of guide wheels is set to two, both of which are rotatably connected to the side wall of the mounting plate, and both of which are matched with the guide rail; By setting up a protective shell, the driven gear and driven gear ring can be protected, thus preventing them from rusting after being splashed by cooling water. At the same time, when the mounting plate rotates, the guide wheels on its surface can be limited by the guide rails on the surface of the protective shell, thereby improving the stability of the mounting plate during rotation, which in turn improves the stability of the cutting machine during rotation, thus preventing the cutting machine from deviating during rotation and causing uneven pipe cuts.

[0012] Preferably, a limiting structure for improving the moving stability of the cutting machine is provided on one side of the fixed plate. The limiting structure includes a limiting sleeve, and the number of the limiting sleeves is set to two. The side walls of the two limiting sleeves are fixedly connected to the mounting plate. A limiting rod is slidably provided inside the two limiting sleeves, and the ends of the two limiting rods are fixedly connected to the fixed plate. By using two limiting sleeves to limit the two limiting rods and the fixed plate that is fixedly connected to the limiting rods, the stability of the fixed plate and the cutting machine during movement can be improved, thereby preventing the cutting machine from shifting during movement and causing uneven pipe cuts.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The present invention provides a construction power pipe cutting device: 1. By setting fixed components, the positions of multiple abutments can be adjusted synchronously at the same time, so that multiple abutments can abut against the inner walls of pipes of different diameters, thereby fixing the device inside pipes of different diameters. Since multiple abutments surround the inner wall of the pipe for support and fixation, uneven force on the pipe can be avoided and deformation can be avoided. This also prevents the pipe from twisting during cutting due to deformation, resulting in an uneven cut.

[0014] 2. By setting up a cutting component and driving the mounting plate to rotate synchronously, the cutting machine set at the end of the mounting plate can perform ring cutting on the pipe. When it is necessary to cut ring pipes of different diameters, the position of the cutting machine can be adjusted by the electric push rod to cut pipes of different diameters. At the same time, the cutting machine blade is continuously cooled by cooling water, thereby preventing the cutting machine blade from generating high temperature due to cutting friction and melting the pipe cut surface in contact with it, so as to avoid the pipe end being melted and then cooled to become uneven.

[0025] Furthermore, the cutting component 3 includes a mounting plate 31, the side wall of which is fixedly connected to the end of the rotating rod 14, an electric push rod 32 is fixedly connected to the top of the mounting plate 31, a fixing plate 33 is fixedly connected to the output end of the electric push rod 32, the fixing plate 33 is L-shaped, a cutting machine 34 is fixedly connected to the surface of the fixing plate 33, and a cooling structure 35 for cooling the blade on the surface of the cutting machine 34 is provided on the surface of the fixing plate 33.

[0026] Furthermore, the cooling structure 35 includes a water storage tank 351, a water supply pipe 352 on the side wall of the water storage tank 351, a micro water pump 353 fixedly connected to the top of the water storage tank 351, an inlet pipe 354 connected to the input end of the micro water pump 353, the end of the inlet pipe 354 extending into the interior of the water storage tank 351, an outlet pipe 355 connected to the output end of the micro water pump 353, the outlet pipe 355 being made of soft rubber material, a nozzle 356 connected to the end of the outlet pipe 355, and the nozzle 356 penetrating the fixing plate 33.

[0027] Furthermore, the bottom of the mounting plate 31 is also provided with a stabilizing structure 4 to improve the stability of the mounting plate 31 when rotating. The stabilizing structure 4 includes a protective shell 41 and guide wheels 42. A rotating rod 14 is set through the protective shell 41 and is rotatably connected to the protective shell 41. Multiple grooves 43 matching the mounting box 21 are opened on the outer side of the protective shell 41. The protective shell 41 is fixedly connected to the mounting bracket 1 by bolts.

A limiting rod 52 is slidably provided inside the two limiting sleeves 51, and the ends of the two limiting rods 52 are fixedly connected to the fixed plate 33.

[0029] Working principle and usage process of this invention: When the gear rotates, it can drive the turntable 24 to rotate through the rotating shaft 22. At the same time, the turntable 24 will drive the bias shaft on its surface to rotate. When the bias shaft rotates, it will drive the drive sleeve 26 and the extension rod 27 to slide relative to the mounting box 21, thereby adjusting the distance between the end block 28 of the extension rod 27 and the mounting bracket 1. By starting the second stepper motor 292, the active gear 295 can drive the active gear ring 293 and the rotating cylinder 291 to rotate. At the same time, the rotating cylinder 291 will drive multiple driven gears 23 to rotate synchronously through the driven gear ring 294. By making multiple synchronous gears rotate synchronously, the positions of multiple abutments 28 can be adjusted synchronously at the same time. Thus, by adjusting the positions of multiple abutments 28 synchronously, multiple abutments 28 can be made to abut against the inner walls of pipes of different diameters, thereby fixing the device inside the pipe. When the cutting machine 34 cuts the inner wall of the pipe, the first step motor 13 drives the rotating rod 14 to rotate, which can drive the mounting plate 31 to rotate synchronously. This allows the cutting machine 34, which is set at the end of the mounting plate 31, to perform annular cutting on the pipe. When it is necessary to cut annular pipes of different diameters, the electric push rod 32 can drive the fixed plate to adjust the position of the cutting machine 34, so that pipes of different diameters can be cut by the cutting machine 34. When the cutting machine 34 cuts the pipe, the micro water pump 353 is started to draw cooling water from the water storage tank 351 through the water inlet pipe 354 and delivers the cooling water to the nozzle 356 through the water outlet pipe 355. The cooling water is then sprayed onto the blade of the cutting machine 34 through the nozzle 356, thereby continuously cooling the blade of the cutting machine 34. This prevents the cutting blade of the cutting machine 34 from generating high temperatures due to cutting friction, which would cause the pipe cut to melt. This also prevents the pipe from becoming uneven after the cut end melts and cools down. If the cooling water in the water storage tank 351 is insufficient, cooling water can be added to the water storage tank 351 through the water replenishment pipe 352.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
