Description

Technical Field

[0001] This utility model relates to the field of cable cutting technology, and more specifically, to a cable cutting device for railway communication construction. Background Technology

[0002] Railway communication systems are core infrastructure ensuring the safe and efficient operation of railway transportation. They undertake critical functions such as transmitting train dispatching instructions, monitoring train operation status, and emergency communication. Cables, as a crucial carrier of these systems, are directly affected by their installation quality, impacting the stability and transmission efficiency of communication signals. Cable cutting is a fundamental and frequent operation during railway communication construction. Whether it's on-site cable laying, joint fabrication, or equipment connection, precise and efficient cable cutting is essential based on actual construction requirements.

[0003] However, the cable cutting devices currently used in railway communication construction still have many problems that fail to meet actual construction needs. Firstly, traditional cable cutting devices rely heavily on manual assistance for cable transport. Operators need to hold the cable to control its direction while simultaneously operating the cutting component. This method not only consumes a lot of manpower but also makes it difficult to ensure uniform cable transport, easily leading to deviations in cutting length. Railway communication cables require high precision in cutting length; excessive deviation directly affects the quality of subsequent cable joint fabrication, and may even cause poor contact, leading to communication signal attenuation or interruption, posing a potential threat to the stable operation of the railway communication system.

[0004] Secondly, the existing cutting devices suffer from poor coordination between the conveying and cutting mechanisms, with most lacking effective cable clamping and positioning structures. During the cutting process, the cable is prone to jumping or shifting due to the cutting force, resulting not only in an uneven cut surface and increased difficulty in subsequent processing, but also in uneven stress on the cutting components, shortening the lifespan of easily damaged parts such as the saw blade. Although some devices are equipped with clamping structures, the clamping force is difficult to adjust. Excessive force can damage the cable's outer sheath and compromise its insulation performance, while insufficient force fails to stabilize the cable, still resulting in cutting deviations.

[0005] Therefore, a cable cutting device for railway communication construction is proposed to address the above problems. Utility Model Content

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a cable cutting device for railway communication construction, which can realize the function of actively conveying cables and performing precise cutting.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A cable cutting device for railway communication construction includes two support plates, with a cutting table fixedly connected to the upper end of both support plates. A saw groove is formed on the upper end of the cutting table, and a conveying mechanism is fixedly connected to the upper end of the cutting table. Two cable bodies are movably connected inside the conveying mechanism, and the cutting mechanism is fixedly connected to the upper end of the cutting table.

[0011] Furthermore, the conveying mechanism includes two positioning plates, the lower ends of which are fixedly connected to the upper end of the cutting table, and connecting blocks are fixedly connected to the left and right ends of the two positioning plates. Two electric drive rods are fixedly connected to the ends of the four connecting blocks that are close to each other, and a conveying component is slidably connected to the outer surfaces of the two electric drive rods.

[0012] Furthermore, the conveying assembly includes an electric drive frame, with a positioning plate two fixedly connected to the left and right walls of the inner cavity of the electric drive frame. Two sliding holes one are opened at the front end of the electric drive frame, and the inner surfaces of the two sliding holes one are slidably connected to the outer surfaces of the two electric drive rods respectively. Two sliding rods one are fixedly connected to the upper and lower walls of the inner cavity of the electric drive frame, and a clamping plate is slidably connected to the outer surfaces of the two sliding rods one. A hydraulic cylinder one is fixedly connected to the inner surface of the sliding rod one, and the output end of the hydraulic cylinder one is fixedly connected to the upper end of the clamping plate.

[0013] Furthermore, the cutting mechanism includes a bracket, the lower end of which is fixedly connected to the upper end of the cutting table. Four sliding rods are fixedly connected to the top wall of the inner cavity of the bracket. The lower ends of the four sliding rods are all fixedly connected to the upper end of the cutting table. Two limiting plates are fixedly connected to the outer surfaces of the four sliding rods. Four springs are fixedly connected to the upper ends of the two limiting plates. Two pressure plates are fixedly connected to the upper ends of the four springs. The inner surfaces of the two pressure plates are slidably connected to the outer surfaces of the four sliding rods. A cutting assembly is slidably connected to the outer surfaces of the four sliding rods.

[0014] Furthermore, the cutting assembly includes a second hydraulic cylinder, the output end of which is fixedly connected to a connecting plate. The upper end of the connecting plate has four sliding holes. A motor is fixedly connected to the inner surface of the connecting plate, and the output end of the motor is fixedly connected to a saw blade via a coupling.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution enables the coordinated operation of the conveying mechanism and the cutting mechanism. From the clamping and precise conveying of the cable to the starting of the saw blade, cutting, and resetting of each component, no frequent manual intervention is required. Operators only need to place and remove the cable, which greatly reduces manual operation steps and waiting time. At the same time, the device can cut two cables simultaneously, further improving the efficiency of a single operation. It can effectively meet the needs of cutting a large number of cables in railway communication construction and shorten the overall construction cycle.

[0019] (2) This solution controls the conveying length, ensuring consistent cable length for each cut and effectively avoiding length deviations caused by manual conveying. Furthermore, the design of the clamping plate and positioning plate, and the pressure plate and limiting plate, protect the cable sheath from damage via rubber pads and stabilize the cable during cutting using spring pressure, preventing cable misalignment and ensuring a smooth cut surface. This reduces cable waste due to cutting quality issues and lowers construction costs. Attached Figure Description

[0030] Example:

[0031] Please see Figure 1-5 A cable cutting device for railway communication construction includes two support plates 1, with a cutting table 2 fixedly connected to the upper end of the two support plates 1. A saw groove 3 is opened on the upper end of the cutting table 2. A conveying mechanism 4 is fixedly connected to the upper end of the cutting table 2. Two cable bodies 5 are movably connected inside the conveying mechanism 4. A cutting mechanism 6 is fixedly connected to the upper end of the cutting table 2.

[0032] This solution uses two support plates 1 to support the cutting table 2. A conveying mechanism 4 and a cutting mechanism 6 are installed on the upper end of the cutting table 2. Through the cooperation of the conveying mechanism 4 and the cutting mechanism 6, the main body of the railway communication cable 5 can be conveyed and cut, which can improve the cutting efficiency.

[0033] Please see Figure 2-3The conveying mechanism 4 includes two positioning plates 41. The lower ends of the two positioning plates 41 are fixedly connected to the upper end of the cutting table 2. The left and right ends of the two positioning plates 41 are fixedly connected to connecting blocks 42. The ends of the four connecting blocks 42 that are close to each other are fixedly connected to two electric drive rods 43. The outer surfaces of the two electric drive rods 43 are slidably connected to a conveying assembly 44. The conveying assembly 44 includes an electric drive frame 441. The left and right walls of the inner cavity of the electric drive frame 441 are fixedly connected to positioning plates 442. The front end of the electric drive frame 441 has two sliding holes 443. The inner surfaces of the two sliding holes 443 are slidably connected to the outer surfaces of the two electric drive rods 43 respectively. The upper and lower walls of the inner cavity of the electric drive frame 441 are fixedly connected to two sliding rods 444. The outer surfaces of the two sliding rods 444 are slidably connected to a clamping plate 445. The inner surface of the sliding rods 444 is fixedly connected to a hydraulic cylinder 446. The output end of the hydraulic cylinder 446 is fixedly connected to the upper end of the clamping plate 445.

[0034] The two electric drive rods 43 adopt a ball screw structure. The rod body is made of high-strength alloy steel. The ball screw has the characteristics of high transmission accuracy and low friction coefficient. It can accurately control the sliding distance of the conveying component 44. Its function is to provide power to the conveying component 44, drive the conveying component 44 to slide along the set direction, and realize the accurate conveying of the cable body 5.

[0035] This solution involves placing two cable bodies 5 on top of two positioning plates 41 and 442, activating hydraulic cylinder 446, and causing clamping plate 445 to move downwards on the outer surface of two sliding rods 444 under the action of hydraulic cylinder 446. This clamps the two cable bodies 5 in conjunction with positioning plate 442. At this time, electric drive frame 441 slides forward along the outer surface of two electric drive rods 43 under the combined action of two sliding holes 443 and two electric drive rods 43, thus delivering the two cable bodies 5 forward. The delivery length can be controlled, which indirectly controls the cable cutting length, allowing the cable to be cut as needed.

[0036] Please see Figure 4-5 The cutting mechanism 6 includes a bracket 61, the lower end of which is fixedly connected to the upper end of the cutting table 2. Four sliding rods 62 are fixedly connected to the top wall of the inner cavity of the bracket 61. The lower ends of the four sliding rods 62 are all fixedly connected to the upper end of the cutting table 2. Two limiting plates 63 are fixedly connected to the outer surfaces of the four sliding rods 62. Four springs 64 are fixedly connected to the upper ends of the two limiting plates 63. Two pressure plates 65 are fixedly connected to the upper ends of the four springs 64. The inner surfaces of the two pressure plates 65 are slidably connected to the outer surfaces of the four sliding rods 62.

[0037] Spring 64 is made of carbon steel, which has good elastic recovery properties. Its function is to provide elastic pressure to pressure plate 65, pressing the cable body 5 tightly during the cutting process to prevent cable slippage. Both pressure plates 65 are made of engineering plastic, with rubber pads also attached to their inner sides. Their function is to contact the surface of the cable body 5 under the action of spring 64, ensuring sufficient clamping force to stabilize the cable while avoiding damage to the cable's outer sheath.

[0038] The outer surfaces of the four sliding rods 62 are slidably connected to a cutting assembly 66. The cutting assembly 66 includes a hydraulic cylinder 661. The outer surface of the hydraulic cylinder 661 is fixedly connected to the inner surface of the bracket 61. The output end of the hydraulic cylinder 661 is fixedly connected to a connecting plate 662. The upper end of the connecting plate 662 has four sliding holes 663. The inner surfaces of the four sliding holes 663 are slidably connected to the outer surfaces of the four sliding rods 62 respectively. The inner surface of the connecting plate 662 is fixedly connected to a motor 664. The output end of the motor 664 is fixedly connected to a saw blade 665 through a coupling.

[0039] This solution uses motor 664 to rotate saw blade 665. When saw blade 665 rotates, hydraulic cylinder 661 is activated, allowing connecting plate 662 to move downwards along the outer surface of the four sliding rods 62 with the cooperation of four sliding holes 663 and four sliding rods 62. The downward movement of connecting plate 662 will move motor 664 and saw blade 665 downwards together. When saw blade 665 contacts the two cable bodies 5, it can cut the two cable bodies 5. In order to make the cutting process more stable, four springs 64 are used in conjunction with two pressure plates 65 and two limiting plates 63 to limit the maximum downward distance of saw blade 665 while ensuring the stability of cutting.

[0040] It should be noted that the specific installation methods, circuit connections, oil circuit connections, and control methods of the motor 664, hydraulic cylinder 446, hydraulic cylinder 661, and electric drive rod 43 in this utility model are all conventional designs and will not be described in detail here. Specifically, a PLC controller is integrated inside the control cabinet. The PLC controller serves as the core of the entire device and is connected to the electric drive rod 43, hydraulic cylinder 446, hydraulic cylinder 661, and motor 664 via wires to achieve unified control of each component. The control methods are divided into manual and automatic control. Manual control is achieved through buttons on the control cabinet surface, including a power switch, emergency stop button, and individual component operation buttons, mainly used for equipment debugging and emergency handling. Automatic control is achieved through a touch screen on the control cabinet surface. Operators can set parameters such as cable cutting length, conveying speed, and cutting speed on the touch screen. After receiving the parameters, the PLC controller automatically controls each component to work collaboratively according to a preset program, reducing manual intervention. The power supply adopts an external 380V industrial power supply, which is connected to the control cabinet via cable. The control cabinet is equipped with a leakage current protector and a circuit breaker. The leakage current protector can quickly cut off the power supply when the device has a leakage, protecting the safety of the operators. The circuit breaker can disconnect when the circuit is overloaded, preventing damage to electrical components due to excessive current. In addition, the control cabinet is also equipped with a backup battery. The backup battery will automatically be put into use in the event of a sudden power failure, driving hydraulic cylinder 446 and hydraulic cylinder 661 to reset, preventing the saw blade 665 from getting stuck in the cable or the mechanism from jamming, thus protecting the equipment from damage.

[0041] Working principle: During railway communication construction, when cable cutting is required, two cable bodies 5 are first placed on top of two positioning plates 41 and 442. Hydraulic cylinder 446 is activated, causing clamping plate 445 to move downwards on the outer surface of two sliding rods 444 under the action of hydraulic cylinder 446, cooperating with positioning plate 442 to clamp the two cable bodies 5. At this time, the electric drive frame 441, under the combined action of two sliding holes 443 and two electric drive rods 43, slides forward along the outer surface of the two electric drive rods 43, thus delivering the two cable bodies 5 forward. Then, the action of the two electric drive rods 43 can be stopped, and motor 664 can be started, allowing the saw blade 665 to move forward under the influence of motor 664. Under the action of the saw blade 665, the hydraulic cylinder 661 can be activated, allowing the connecting plate 662 to move downward along the outer surface of the four sliding rods 62 with the cooperation of the four sliding holes 663 and the four sliding rods 62. The downward movement of the connecting plate 662 will move the motor 664 and the saw blade 665 downward together. When the saw blade 665 contacts the two cable bodies 5, it can cut the two cable bodies 5. In order to make the cutting process more stable, four springs 64 are used in conjunction with two pressure plates 65 and two limit plates 63 to ensure the stability during cutting. In the above manner, the delivery process and the cutting process can be completed alternately, which can greatly improve the cutting efficiency of the cable.

[0042] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
