Description

Technical Field

[0001] This utility model relates to the technical field of PVC power cable protection pipe processing equipment, specifically a PVC power cable protection pipe cutting device. Background Technology

[0002] In power engineering construction, PVC power cable protection pipes are widely used for cable laying and protection due to their excellent insulation properties, corrosion resistance, and high strength. However, in actual construction, the PVC power cable protection pipes need to be cut into appropriate lengths according to different project requirements.

[0003] Currently, the common methods for cutting PVC power cable protection pipes are as follows. The first method is manual cutting using hand-operated tools, such as a hand saw. This method has several significant drawbacks. First, manual operation is labor-intensive; workers need to expend considerable physical strength to complete the cutting work, especially when cutting large quantities of pipes, leading to worker fatigue and low efficiency. Second, cutting accuracy is difficult to guarantee; different workers use different techniques and apply varying degrees of force, resulting in significant errors in the length of the cut pipes, which cannot meet the requirements of some projects with high precision demands. Furthermore, hand saws produce uneven cut surfaces and burrs, which not only affect the appearance of the pipes but may also scratch the cable sheath during cable installation, posing a safety hazard.

[0004] The second common cutting method is using a regular electric cutting machine. While regular electric cutting machines improve cutting efficiency to some extent, they still have shortcomings. On the one hand, when cutting PVC power cable protection pipes, the pipe's own arc-shaped structure makes it prone to rolling during the cutting process, causing the cutting position to shift and affecting cutting accuracy and results. On the other hand, regular electric cutting machines generate a large amount of debris and dust during the cutting process. This debris and dust not only pollute the working environment and harm the health of operators, but may also enter the cutting machine, affecting its normal operation and reducing its service life.

[0005] Some cutting equipment uses simple fixing and cutting structures, making it difficult to adapt to PVC power cable protection pipes of different diameters and wall thicknesses. When it is necessary to cut pipes of different specifications, operators need to spend a lot of time adjusting the equipment and replacing parts, which is cumbersome and reduces the equipment's versatility and work efficiency.

[0006] In summary, existing methods and equipment for cutting PVC power cable protection pipes suffer from problems such as high labor intensity, low cutting accuracy, poor cut surface quality, easy environmental pollution, and poor versatility. These issues make it difficult to meet the requirements of efficient, precise, and environmentally friendly construction in modern power engineering. Therefore, it is urgent to design a new type of PVC power cable protection pipe cutting device to solve these problems. Utility Model Content

[0007] To address the problems mentioned in the background art, the purpose of this utility model is to provide a PVC power cable protection pipe cutting device, which has the advantages of good cutting effect and ease of use.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a PVC power cable protection pipe cutting device, comprising a cutting table, a support frame fixedly connected to the top of the cutting table, sleeves fixedly connected to the surface of the support frame, a movable rod slidably connected inside the sleeves, and several sleeves; a first electric cylinder fixedly connected to the surface of the support frame, a cutting assembly fixedly connected to the bottom of the movable rod, the output end of the first electric cylinder fixedly connected to the cutting assembly; a drive box fixedly connected to the left side of the support frame via a bracket, a threaded rod rotatably connected inside the drive box, clamps slidably connected to the front and rear sides of the drive box, the clamps being threadedly connected to the threaded rod; a first motor fixedly connected to the front of the drive box, the output end of the first motor being fixedly connected to the threaded rod; a lifting assembly provided at the top of the support frame; a protective cover provided at the top of the cutting table; observation windows provided on the front and sides of the protective cover; and a dust extraction assembly provided above the protective cover.

[0009] In a preferred embodiment of this invention, the lifting assembly includes a work box fixedly connected to the top of the support frame, a first threaded rod rotatably connected inside the work box, a connecting column slidably connected inside the work box, the connecting column being fixedly connected to a protective cover, the first threaded rod being threadedly connected to the connecting column, and a second motor fixedly connected to the top of the work box, the output end of the second motor being fixedly connected to the first threaded rod.

[0010] In a preferred embodiment of this invention, the dust collection assembly includes dust collection pipes fixedly connected to both sides of the work box, a filter box fixedly connected to the back of the cutting table, an air inlet of the filter box and an air outlet of the dust collection pipe connected by a pipe, a filter plate and an activated carbon adsorption plate slidably connected inside the filter box, the back of the filter plate and the activated carbon adsorption plate both extending to the back of the filter box and fixedly connected to a handle, a fan fixedly connected inside the filter box by a bracket, the activated carbon adsorption plate being located below the filter plate, and the fan being located below the activated carbon adsorption plate.

[0011] As a preferred embodiment of this utility model, a support plate is fixedly connected to the left side of the drive box, and a second electric cylinder is fixedly connected to the top of the support plate. The output end of the second electric cylinder extends to the bottom of the support plate and is fixedly connected to a pressure plate.

[0012] As a preferred embodiment of this utility model, the top of the cutting table is provided with a groove, and a rubber pad is fixedly connected inside the groove. The top of the rubber pad is provided with an anti-slip groove, and there are several anti-slip grooves, which are evenly distributed on the top of the rubber pad. The surfaces of the clamping plate and the pressure plate are both provided with anti-slip textures.

[0013] As a preferred embodiment of this invention, the top of the cutting table is provided with scale lines.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model adopts a structure including a cutting table, support frame, sleeve, movable rod, first electric cylinder, cutting assembly, drive box, threaded rods (both positive and negative), clamping plates, first motor, lifting assembly, protective cover, and dust collection assembly. This effectively solves the problems of high labor intensity, low cutting accuracy, and severe dust pollution associated with existing cutting methods. The threaded rods in the drive box rotate under the drive of the first motor, causing the two clamping plates to move synchronously in opposite directions. This achieves automatic centering and clamping of PVC power cable protection pipes of different diameters, ensuring stable fixation of the pipes during cutting and preventing positional shifts due to rolling. The first electric cylinder drives the cutting assembly to smoothly rise and fall along the movable rod inside the sleeve, precisely controlling the cutting depth and speed to ensure a smooth, burr-free cut surface. The protective cover effectively blocks flying debris during cutting, and, in conjunction with the dust collection assembly, collects dust promptly, preventing pollution of the working environment and harm to operators' health. The lifting assembly allows adjustment of the protective cover's height as needed, facilitating pipe loading and unloading while creating a closed space during cutting to enhance dust prevention. The overall structure works in synergy, significantly improving cutting efficiency and precision while reducing labor intensity. This device has the advantages of good cutting effect and ease of use.

[0016] 2. This utility model provides a stable and precise driving method for the lifting and lowering of the protective cover by setting up a working box, a first threaded rod, a connecting column, and a second motor. After the second motor starts, it drives the first threaded rod to rotate, and the connecting column, which is threaded to the first threaded rod, will smoothly rise and fall along the inside of the working box, thereby driving the protective cover, which is fixedly connected to the connecting column, to rise and fall synchronously. This design is not only easy to operate, as the opening and closing of the protective cover can be achieved simply by controlling the forward and reverse rotation of the second motor, greatly reducing the labor intensity of the operator; but also, through the threaded rod transmission, the lifting and lowering height of the protective cover can be precisely controlled, ensuring that it fits tightly against the cutting table when closed, effectively preventing debris and dust from overflowing from the gaps during the cutting process. When used in conjunction with the dust collection component, it can collect dust to the maximum extent and improve the dust removal effect; at the same time, the sliding connection structure between the connecting column and the working box enhances the stability of the protective cover during the lifting and lowering process, avoiding damage to the protective cover from collision with the cutting table due to shaking, extending the service life of the equipment, and further improving the practicality and reliability of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, a PVC power cable protection pipe cutting device includes a cutting table 1, a support frame 2 fixedly connected to the top of the cutting table 1, a sleeve 3 fixedly connected to the surface of the support frame 2, a movable rod 4 slidably connected inside the sleeve 3, and several sleeves 3. A first electric cylinder is fixedly connected to the surface of the support frame 2, a cutting component 5 is fixedly connected to the bottom of the movable rod 4, and the output end of the first electric cylinder is fixedly connected to the cutting component 5. A drive box 6 is fixedly connected to the left side of the support frame 2 via a bracket. A threaded rod with positive and negative threads is rotatably connected inside the drive box 6. Clamping plates 8 are slidably connected to the front and rear sides of the drive box 6 and are threadedly connected to the threaded rod with positive and negative threads. A first motor 7 is fixedly connected to the front of the drive box 6, and the output end of the first motor 7 is fixedly connected to the threaded rod with positive and negative threads. A lifting component 9 is provided on the top of the support frame 2, a protective cover 10 is provided on the top of the cutting table 1, observation windows 20 are provided on the front and sides of the protective cover 10, and a dust suction component 11 is provided above the protective cover 10.

[0024] refer to Figure 3 The lifting assembly 9 includes a work box 12 fixedly connected to the top of the support frame 2. A first threaded rod 13 is rotatably connected inside the work box 12. A connecting column 15 is slidably connected inside the work box 12. The connecting column 15 is fixedly connected to the protective cover 10. The first threaded rod 13 is threadedly connected to the connecting column 15. A second motor 14 is fixedly connected to the top of the work box 12. The output end of the second motor 14 is fixedly connected to the first threaded rod 13.

[0025] As a technical optimization of this utility model, by setting up a working box 12, a first threaded rod 13, a connecting column 15, and a second motor 14, a stable and precise driving method is provided for the lifting and lowering of the protective cover 10. After the second motor 14 starts, it drives the first threaded rod 13 to rotate. The connecting column 15, which is threadedly connected to the first threaded rod 13, will smoothly rise and fall along the inside of the working box 12, thereby driving the protective cover 10, which is fixedly connected to the connecting column 15, to rise and fall synchronously. This design is not only easy to operate, as the opening and closing of the protective cover 10 can be achieved simply by controlling the forward and reverse rotation of the second motor 14, greatly reducing the labor intensity of the operator; but also, through the threaded rod transmission, the lifting and lowering height of the protective cover 10 can be precisely controlled, ensuring that it fits tightly against the cutting table 1 when closed, effectively preventing debris and dust from overflowing from the gaps during the cutting process. When used in conjunction with the dust collection component 11, it can collect dust to the maximum extent and improve the dust removal effect; at the same time, the sliding connection structure between the connecting column 15 and the working box 12 enhances the stability of the protective cover 10 during the lifting and lowering process, avoiding damage to the protective cover due to shaking. The protective cover 10 is damaged by collision with the cutting table 1, which extends the service life of the equipment and further improves the practicality and reliability of the device. The surfaces of the first threaded rod 13 and the positive and negative threaded rods are covered with rubber telescopic sleeves to prevent dust from adhering to the surfaces of the first threaded rod 13 and the positive and negative threaded rods, which would prevent the first threaded rod 13 and the positive and negative threaded rods from running. The above-mentioned rubber telescopic sleeves are common existing technology and are common knowledge to those skilled in the art. This application will not describe them in detail. At the same time, the operator can also use other methods to protect the first threaded rod 13 and the positive and negative threaded rods from dust according to actual needs. The rubber telescopic sleeves are not shown.

[0026] refer to Figure 2 The dust collection assembly 11 includes a dust collection pipe 16 fixedly connected to both sides of the work box 12. A filter box 17 is fixedly connected to the back of the cutting table 1. The air inlet of the filter box 17 is connected to the air outlet of the dust collection pipe 16 through a pipe. A filter plate 18 and an activated carbon adsorption plate 19 are slidably connected inside the filter box 17. The back of both the filter plate 18 and the activated carbon adsorption plate 19 extends to the back of the filter box 17 and is fixedly connected to a handle. A fan is fixedly connected inside the filter box 17 through a bracket. The activated carbon adsorption plate 19 is located below the filter plate 18, and the fan is located below the activated carbon adsorption plate 19.

[0027] As a technical optimization of this utility model, the dust pollution problem during the cutting process is efficiently solved by setting up a suction pipe 16, a filter box 17, a filter plate 18, an activated carbon adsorption plate 19, and a fan. When cutting, the fan starts, generating negative pressure inside the filter box 17. Dust above the cutting table 1 is sucked into the filter box 17 through the suction pipe 16. First, it passes through the filter plate 18, whose mesh can intercept most of the larger debris particles, preventing them from entering subsequent structures and causing blockages. Then, the airflow continues downwards through the activated carbon adsorption plate 19. The porous structure of the activated carbon effectively adsorbs fine dust particles and odors generated during cutting, purifying the exhaust air. This protects the health of the operators and prevents dust from entering the cutting equipment and causing wear on precision components, extending the equipment's service life. The handles on the back of the filter plate 18 and the activated carbon adsorption plate 19 allow operators to easily remove them from the filter box 17 for cleaning or replacement periodically. Maintenance is simple and quick, ensuring the long-term stable performance of the dust collection assembly 11 and further improving the environmental friendliness and economy of the device.

[0028] refer to Figure 3 A support plate 21 is fixedly connected to the left side of the drive box 6. A second electric cylinder 22 is fixedly connected to the top of the support plate 21. The output end of the second electric cylinder 22 extends to the bottom of the support plate 21 and is fixedly connected to a pressure plate 23.

[0029] As a technical optimization of this utility model, the support plate 21, the second electric cylinder 22, and the pressure plate 23 serve as auxiliary fixing structures to effectively enhance the fixing effect of the PVC power cable protection pipe. After the clamping plate 8 in the drive box 6 initially clamps the pipe, the second electric cylinder 22 is activated, and its output end extends downward to push the pressure plate 23 down. The pressure plate 23 cooperates with the rubber pad 24 on the top of the cutting table 1 to apply pressure to the top and bottom of the pipe simultaneously. Especially for large-diameter or thin-walled PVC power cable protection pipes, it can effectively prevent them from rolling or shifting during the cutting process due to their arc-shaped structure, ensuring accurate cutting position. This double fixing method makes the pipe more stable during cutting, avoiding problems such as uneven cutting surface and increased burrs caused by pipe shaking, thus improving cutting quality. At the same time, the setting of the pressure plate 23 expands the applicability of the device to pipes of different specifications. It can complete the cutting of pipes of different diameters and wall thicknesses without frequent replacement of parts, making operation simpler and significantly improving the versatility and work efficiency of the equipment.

[0030] refer to Figure 4 The top of the cutting table 1 is provided with a groove, and a rubber pad 24 is fixedly connected inside the groove. The top of the rubber pad 24 is provided with anti-slip grooves, and there are several anti-slip grooves, which are evenly distributed on the top of the rubber pad 24. The surfaces of the clamping plate 8 and the pressure plate 23 are both provided with anti-slip textures.

[0031] As a technical optimization of this utility model, the grooves, rubber pads 24, anti-slip grooves, and anti-slip patterns on the surfaces of the clamping plate 8 and pressure plate 23 work together to enhance the stability of the pipe fixing. The rubber pads 24 in the grooves can buffer the vibration generated during the cutting process, preventing the pipe surface from being damaged by hard impacts; the anti-slip grooves evenly distributed on the top of the rubber pads 24 can increase the friction with the pipe surface, preventing the pipe from sliding in the horizontal direction; the anti-slip patterns on the surfaces of the clamping plate 8 and pressure plate 23 are in close contact with the pipe surface during clamping and pressing, further increasing the friction in the vertical direction, effectively preventing the pipe from rotating due to the cutting force. The combined use of these structures ensures that the pipe remains stable throughout the cutting process, the cutting position is accurate, the cutting surface is flat and smooth, reducing subsequent grinding and other processing steps, improving the quality of the finished product, and reducing pipe waste caused by cutting errors, thus saving production costs.

[0032] refer to Figure 4 The top of the cutting table 1 is provided with a scale line 25.

[0033] As a technical optimization of this utility model, the graduation line 25 on the top of the cutting table 1 facilitates the measurement of the cutting length of PVC power cable protection pipes. The graduation line 25 features a clear marking design, allowing operators to directly determine the cutting position by observing the graduation line 25 when placing the pipe, eliminating the need for additional measuring tools, reducing measurement steps and labor intensity. The precise marking of the graduation line 25 effectively avoids length deviations caused by visual errors or improper operation during manual measurement, ensuring that the length of the cut pipe meets project requirements and improving cutting accuracy. For situations requiring batch cutting of pipes of the same length, the graduation line 25 can also help operators quickly locate the pipes, ensuring consistency in the cutting length of multiple pipes and meeting the dual requirements of modern power engineering for construction efficiency and quality.

[0034] The working principle and usage process of this utility model are as follows: When using it, the following steps are included:

[0035] I. Preparations before use

[0036] After powering on the equipment, check whether the lifting assembly 9, specifically the connecting column 15, can smoothly move the protective cover 10 up and down without jamming; whether the connection between the suction pipe 16 and the filter box 17 is sealed; and whether the rubber pad 24, anti-slip texture, and other anti-slip structures are intact. Pay special attention to: checking whether the graduation lines 25 on the cutting table 1 are clear to ensure accurate subsequent length measurements; confirming that the filter plate 18 and activated carbon adsorption plate 19 inside the filter box 17 are properly installed and that the handle is not loose.

[0037] Before pre-treatment, clean the surface of the PVC power cable protection pipe to be cut to ensure that both ends of the pipe are flat. Mark the cutting position on the surface of the pipe according to the project requirements. The initial positioning can be directly compared with the scale line 25 on the cutting table.

[0038] II. Pipe Clamping and Positioning

[0039] Start the first motor 7 to drive the forward and reverse threaded rod to rotate, so that the two clamping plates 8 move synchronously towards each other to the maximum distance, and then place the pipe to be cut. Start the first motor 7 again to make the clamping plates 8 fit against the outer wall of the pipe and clamp it tightly. Then start the second electric cylinder 22, and its output end pushes the pressure plate 23 downward until the anti-slip texture of the pressure plate 23 is in close contact with the top of the pipe, forming an upper and lower clamp with the rubber pad 24 of the cutting table 1.

[0040] III. Enclosure of the lifting and cutting areas of the protective cover 10

[0041] The height adjustment of the protective cover 10 starts the second motor 14, which drives the first threaded rod 13 to rotate. The connecting column 15 slides along the inner wall of the work box 12, causing the protective cover 10 to descend to the bottom, so that the bottom edge of the protective cover 10 fits against the top of the cutting table 1, forming a relatively closed space to block the flying debris.

[0042] IV. Cutting Operation

[0043] The cutting depth and speed are set according to the pipe wall thickness. The stroke of the first electric cylinder is set through the control system or manually. The recommended initial cutting speed is 0.5-1cm / s to ensure a smooth and burr-free cut surface. The first electric cylinder is not shown.

[0044] Start cutting and dust collection

[0045] First, turn on the fan of the vacuum assembly 11. After a stable negative pressure is formed in the filter box 17, start the cutting assembly 5. The first electric cylinder drives the cutting assembly 5 to descend at a constant speed along the movable rod 4 inside the sleeve 3 until the cutting is completed. During the cutting process, the cutting progress is monitored through the observation window 20 to avoid overload. The vacuum pipe 16 simultaneously adsorbs the dust generated during cutting. Large particles of debris are intercepted by the filter plate 18, and fine dust and odors are purified by the activated carbon adsorption plate 19. The purified air is discharged from the exhaust port of the filter box 17.

[0046] The cutting component 5, the first electric cylinder and the second electric cylinder 22 mentioned above are all common existing technologies and are common knowledge to those skilled in the art. Therefore, they will not be described in detail in this application.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
