Description

Technical Field

[0001] This invention relates to the field of cutting device technology, specifically a cutting device for the production of cable protection pipes. Background Technology

[0002] Cable protection pipe cutting devices are used to cut cable protection pipes into two sections. Some cable protection pipe cutting devices generally require the cable to stop moving before cutting it. In processes where the cable continues to move forward, stopping the cable reduces the efficiency of cutting the cable.

[0003] The shortcomings of existing cable cutting devices are: Prior art CN109773854B discloses a cable protection pipe cutting device, which includes a pushing mechanism, a clamping mechanism, and a cutting mechanism disposed on a base plate, wherein the cutting mechanism is disposed between the clamping mechanism and the pushing mechanism. The advantages of this invention are: this invention can cut the protection pipe into segments of varying lengths as needed, eliminating the need for manual cutting, resulting in high cutting efficiency, preventing injury to the operator, and improving safety.

[0004] The above-mentioned technology requires the cable to stop moving when cutting the cable. In processes where the cable needs to move continuously forward, stopping the cable reduces the efficiency of cutting the cable. Therefore, a cutting device for cable protection pipe production is needed to solve this problem, which can cut the cable synchronously with the cable and avoid the cable from obstructing the moving cutting equipment. Summary of the Invention

[0005] One objective of this application is to provide a cutting device for the production of cable protection pipes, which can solve the technical problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for producing cable protection pipes, comprising a frame, a plate, and a frame body. The plate is movably installed on the inner side of the frame, and the frame body is installed on the top of the plate. A hydraulic cylinder is installed on the top of the frame body, and a piston rod is installed on the output end of the hydraulic cylinder. A cutter is installed on one end of the piston rod, and the cutter is located on the inner side of the frame body. The front of the second plate is provided with a configuration mechanism, which includes a connecting rope and a counterweight. One end of the connecting rope is connected to one end of the second plate, and the counterweight is installed on one end of the connecting rope.

[0007] Preferably, a plurality of support columns are symmetrically installed at the bottom of the frame, a plate is installed on the right side of the frame, and a controller is installed on the top of the plate, and the controller is electrically connected to the hydraulic cylinder.

[0008] Preferably, a plurality of rotating wheels are movably installed through the inner side of the frame one, and the rotating wheels are located below the plate two.

[0009] Preferably, limit rods are symmetrically installed on the inner side of the frame one, and the limit rods are located above the plate two.

[0010] Preferably, hydraulic cylinders are symmetrically installed on both sides of the frame, and the hydraulic cylinders are electrically connected to the controller. A piston rod is installed at the output end of the hydraulic cylinder, and a fixed arc plate is installed at one end of the piston rod, with the fixed arc plate located on the inner side of the frame.

[0011] Preferably, a limiting plate is installed on the inner side of the frame one, and the limiting plate is located in front of the plate two. The top of the limiting plate is through which the frame two is installed. The connecting rope is located inside the frame two. A rotating rod one is movably installed through the inner side of the frame two, and the rotating rod one is located below the connecting rope.

[0012] Preferably, multiple springs are symmetrically installed on the back of the limiting plate, and a buffer plate is installed on one end of each spring, with two buffer plates located on both sides of the connecting rope.

[0013] Preferably, a plurality of dampers are installed on the back of the limiting plate, and the input end of the damper is connected to the front of the buffer plate.

[0014] Preferably, rods are symmetrically installed on the front and back of the frame one, and support columns are symmetrically installed on the top of the rods. A frame three is installed at one end of the support column two, and the frame three is located inside the frame. Multiple rotating rods two are movably installed through the inner side of the frame three.

[0015] Preferably, a plate three is installed on the top of the frame one, a hydraulic cylinder three is installed on the right side of the plate three, and the hydraulic cylinder three is electrically connected to the controller. A piston rod three is installed at the output end of the hydraulic cylinder three, and a push rod is installed at one end of the piston rod three, and the push rod is located on the left side of the plate three.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When cutting cables, this invention allows the cutter to move backward along with the cable, enabling the cable to be cut without stopping, thus improving cutting efficiency. After the cable protection tube is cut by the cutter, the cutter moves upward, and the fixed arc plate moves to both sides, thereby releasing the clamp on the cable protection tube. Then, the counterweight moves downward under the action of gravity, thereby driving the connecting rope downward. When the connecting rope moves downward, it drives the second plate forward, so that the second plate can return to the front without the need for a transmission device, saving costs and facilitating the subsequent movement of the second plate along with the cable protection tube to cut the cable protection tube again.

[0017] 2. In this invention, when plate two moves forward under the pull of the counterweight, plate two first contacts the buffer plate, and then the spring buffers the buffer plate, thereby reducing the impact force at the moment of collision, thereby reducing the damage to hydraulic cylinder one and hydraulic cylinder two, and extending the service life of the equipment.

[0018] 3. In this invention, after the cutter cuts the cable protection tube into two sections, the fixed arc plate moves to both sides to release the clamping of the cable protection tube. Then, the cable protection tube falls above the rotating rod two, and the cable protection tube will not contact the plate two, thereby avoiding the cable protection tube from hindering the movement of the plate two. This makes it easier for the plate two to move forward under the pull of the counterweight, thus avoiding the plate two being unable to move forward to the normal position due to the obstruction of the cable protection tube, and ensuring the normal movement of the plate two.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of the present invention provides a cutting device for producing cable protection pipes. A plate 6 is movably installed inside the frame 1. A frame 8 is installed on the top of the plate 6. A hydraulic cylinder 12 is installed on the top of the frame 8. A piston rod 13 is installed at the output end of the hydraulic cylinder 12. A cutter 14 is installed at one end of the piston rod 13 and is located inside the frame 8. Hydraulic cylinders 9 are symmetrically installed on both sides of the frame 8. The hydraulic cylinders 9 are electrically connected to the controller 4. A piston rod 10 is installed at the output end of the hydraulic cylinder 9. A fixed arc plate 11 is installed at one end of the piston rod 10 and is located inside the frame 8. Furthermore, frame 1 provides mounting positions for other components of the equipment, plate 2 6 provides mounting positions for frame 8, and plate 2 6 can move back and forth. When plate 2 6 moves back and forth, it drives the cutter 14 to move back and forth, thus facilitating the movement of the cutter 14 along with the protective tube to cut the protective tube. Frame 8 provides mounting positions for hydraulic cylinder 2 12 and hydraulic cylinder 1 9. Hydraulic cylinder 2 12 converts hydraulic energy into kinetic energy, thereby driving piston rod 2 13 to move up and down. When piston rod 2 13 moves up and down, it drives the cutter 14 to move up and down. The cable protection pipe is cut by moving downwards, so that the cable protection pipe is cut into two sections. The hydraulic cylinder 9 can drive the piston rod 10 to move left and right. The piston rod 10 can drive the fixed arc plate 11 to move left and right by moving left and right. The fixed arc plate 11 can clamp the protection pipe located inside the two fixed arc plates 11 by moving inwards. After the fixed arc plate 11 clamps the cable protection pipe, the fixed arc plate 11 is driven by the cable protection pipe to move backwards together, thereby driving the frame 8, the cutter 14 and the plate 6 to move backwards together. Furthermore, the cable protection pipe is first fed from front to back into the inner side of the two fixed arc plates 11. After the cable protection pipe moves backward a certain length, the controller 4 controls the hydraulic cylinder 9 to work. The hydraulic cylinder 9 drives the fixed arc plates 11 to move inward to clamp the cable protection pipe, thereby causing the cable protection pipe to move backward along with the fixed arc plates 11. This, in turn, drives the frame 8, the plate 6, and the cutter 14 to move backward together. Subsequently, the controller 4 controls the hydraulic cylinder 12 to work. The hydraulic cylinder 12 drives the cutter 14 to move downward to cut the cable protection pipe, so that the cable protection pipe is cut into two sections.

[0025] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides a cutting device for producing cable protection pipes. The front of the plate 6 is provided with a configuration mechanism, which includes a connecting rope 15 and a counterweight 16. One end of the connecting rope 15 is connected to one end of the plate 6, and the counterweight 16 is installed on one end of the connecting rope 15. Furthermore, as plate 26 moves backward, and the cable protection pipe is cut by cutter 14, controller 4 controls hydraulic cylinder 212 to work and drive cutter 14 to move upward. Then, controller 4 controls hydraulic cylinder 19 to work and drive fixed arc plate 11 to move to both sides, thereby releasing the clamp on the cable protection pipe. Then, counterweight 16 moves downward under the action of gravity, thereby driving connecting rope 15 to move downward. When connecting rope 15 moves downward, it drives plate 26 to move forward, so that plate 26 returns to the front again, making it convenient for plate 26 to move backward together with the cable protection pipe to achieve the cutting of cable protection pipe by cutter 14.

[0026] Please see Figure 1 and Figure 2 An embodiment of the present invention provides a cutting device for producing cable protection pipes, wherein multiple support columns 2 are symmetrically installed at the bottom of the frame 1, a plate 3 is installed on the right side of the frame 1, and a controller 4 is installed on the top of the plate 3, and the controller 4 is electrically connected to the hydraulic cylinder 12. Furthermore, support column 2 is used to provide support for frame 1, and plate 3 is used to provide an installation position for controller 4. Controller 4 controls hydraulic cylinder 9, hydraulic cylinder 12 and hydraulic cylinder 28.

[0027] Please see Figure 1 and Figure 2 An embodiment of the present invention provides a cutting device for producing cable protection pipes, wherein multiple rotating wheels 5 are movably installed through the inner side of the frame 1, the rotating wheels 5 are located below the plate 6, and limit rods 7 are symmetrically installed on the inner side of the frame 1, and the limit rods 7 are located above the plate 6. Furthermore, the rotating wheel 5 provides support for the second plate 6, and the rotating wheel 5 reduces the resistance encountered by the second plate 6 during its forward and backward movement by rotating. The limiting rod 7 is used to limit the bottom of the second plate 6 to prevent the second plate 6 from tilting upward, thereby preventing the frame 8 from tipping over and ensuring the stability of the second plate 6 when it moves forward and backward in parallel.

[0028] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides a cutting device for producing cable protection pipes, wherein a limiting plate 17 is installed on the inner side of a frame 1, and the limiting plate 17 is located in front of a plate 6, a frame 18 is installed through the top of the limiting plate 17, a connecting rope 15 is located inside the frame 18, a rotating rod 19 is movably installed through the inner side of the frame 18, and the rotating rod 19 is located below the connecting rope 15. Furthermore, the limiting plate 17 is used to limit the front of the second plate 6 to prevent the second plate 6 from moving forward and detaching from the first frame 1. The second frame 18 is used to provide an installation position for the first rotating rod 19. The first rotating rod 19 can provide support for the connecting rope 15, preventing the connecting rope 15 from directly contacting the second frame 18. Moreover, the first rotating rod 19 reduces the friction force on the connecting rope 15 when it moves by rotating, thereby reducing the damage to the connecting rope 15 by friction and extending the service life of the connecting rope 15.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5An embodiment of the present invention provides a cutting device for producing cable protection pipes, wherein multiple springs 20 are symmetrically installed on the back of the limiting plate 17, and a buffer plate 21 is installed on one end of the spring 20, and the two buffer plates 21 are located on both sides of the connecting rope 15. Furthermore, the spring 20 provides cushioning for the buffer plate 21, reducing the impact damage to the buffer plate 21. The buffer plate 21 is used to cushion the plate body 6. When the plate body 6 is pulled forward by the counterweight 16, the plate body 6 first contacts the buffer plate 21, and then the spring 20 cushions the buffer plate 21, thereby reducing the impact force at the moment of collision, and thus reducing the impact damage to the hydraulic cylinder 9 and the hydraulic cylinder 12.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The present invention provides an embodiment of a cutting device for producing cable protection pipes, wherein a plurality of dampers 22 are installed on the back of the limiting plate 17, and the input end of the damper 22 is connected to the front of the buffer plate 21. Furthermore, the damper 22 is used to quickly restore the impacted buffer plate 21 and spring 20 to a stationary state, preventing the buffer plate 21 and spring 20 from repeatedly bouncing and shaking. When the plate 26 moves forward and collides with the buffer plate 21, the spring 20 buffers the impact force, reducing the damage caused by the impact. Then the damper 22 makes the spring 20 and buffer plate 21 quickly return to a stationary state.

[0031] Please see Figure 1 and Figure 6 An embodiment of the present invention provides a cutting device for producing cable protection pipes, wherein rods 23 are symmetrically installed on the front and back of frame 1, support columns 24 are symmetrically installed on the top of rods 23, frame 3 25 is installed at one end of support column 24, and frame 3 25 is located inside frame 8, and multiple rotating rods 26 are movably installed through the inside of frame 3 25. Furthermore, rod 23 provides an installation position for support column 24, which in turn provides support for frame 3 25. Frame 3 25 provides an installation position for rotating rod 26, which in turn provides support for the cable protection pipe. The rotating rod 26 reduces the friction force experienced by the cable protection pipe when it moves backward by rotating, thereby reducing the resistance experienced by the cable protection pipe when it moves backward. After the cutter 14 cuts the cable protection pipe into two sections, the fixed arc plate 11 moves to both sides to release the clamping of the cable protection pipe. Then the cable protection pipe falls above the rotating rod 26, and the cable protection pipe will not contact plate 26, thus avoiding the cable protection pipe from hindering the movement of plate 26. This makes it easier for plate 26 to move forward under the pull of the counterweight 16, thus preventing plate 26 from being unable to move forward to the normal position due to the obstruction of the cable protection pipe.

[0032] Please see Figure 1 , Figure 7 and Figure 8 An embodiment of the present invention provides a cutting device for producing cable protection pipes, wherein a plate 27 is installed on the top of a frame 1, a hydraulic cylinder 28 is installed on the right side of the plate 27, and the hydraulic cylinder 28 is electrically connected to a controller 4, a piston rod 29 is installed at the output end of the hydraulic cylinder 28, and a push rod 30 is installed at one end of the piston rod 29, and the push rod 30 is located on the left side of the plate 27; Furthermore, plate 3 27 provides an installation position for hydraulic cylinder 3 28. Under the control of controller 4, hydraulic cylinder 3 28 converts hydraulic energy into kinetic energy to drive piston rod 3 29 to move left and right. When piston rod 3 29 moves left and right, it drives push rod 30 to move left and right. Push rod 30 pushes the cut cable protection pipe located above frame 3 25 by moving to the left, so that the cut cable protection pipe is pushed to the left and falls into the pre-placed collection container, avoiding the cut cable protection pipe affecting the backward movement of the cable protection pipe that has not been cut.

[0033] Working Principle: Before using the cable protection pipe cutting device, check whether there are any problems affecting its use. First, feed the cable protection pipe from front to back into the inner side of the two fixed arc plates 11. After the cable protection pipe moves backward a certain length, the controller 4 controls the hydraulic cylinder 9 to work. The hydraulic cylinder 9 drives the fixed arc plates 11 to move inward to clamp the cable protection pipe, thereby causing the cable protection pipe to move backward along with the fixed arc plates 11, which in turn drives the frame 8, plate 6, and cutter. Cutter 14 moves backward together with the cable protection pipe. Then, controller 4 controls hydraulic cylinder 12 to work, which drives cutter 14 downward to cut the cable protection pipe into two sections. After the cable protection pipe is cut by cutter 14, controller 4 controls hydraulic cylinder 12 to work and drive cutter 14 upward. Then, controller 4 controls hydraulic cylinder 9 to work and drive fixed arc plate 11 to move to both sides, thereby releasing the clamp on the cable protection pipe. Then, counterweight 16 moves downward under the action of gravity, thereby driving connecting rope 15 downward. When the connecting rope 15 moves downwards, it drives the second plate 6 forward, causing the second plate 6 to return to the front. When the second plate 6 is pulled forward by the counterweight 16, the second plate 6 first contacts the buffer plate 21, and then the spring 20 buffers the buffer plate 21, thereby reducing the impact force at the moment of collision and reducing the damage to the hydraulic cylinder 9 and hydraulic cylinder 12. Then the damper 22 makes the spring 20 and the buffer plate 21 quickly return to rest. After the cutter 14 cuts the cable protection pipe into two sections, the cable protection pipe falls on the rotating rod 26. In this way, the cable protection pipe will not contact the plate 2 6, thus avoiding the cable protection pipe from hindering the movement of the plate 2 6. This makes it easier for the plate 2 6 to move forward under the pull of the counterweight 16, thus avoiding the plate 2 6 being unable to move forward to the normal position due to the obstruction of the cable protection pipe. Then, the hydraulic cylinder 3 28 drives the push rod 30 to move to the left. The push rod 30 pushes the cut-off cable protection pipe located above the frame 3 25 by moving to the left, so that the cut-off cable protection pipe is pushed to the left and falls into the pre-placed collection container.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the rights involved.
