Description

Technical Field

[0001] This utility model relates to the field of cable cutting technology, specifically a cable cutting device for electrical engineering installation. Background Technology

[0002] Cable cutting is a routine operation in power construction, communication engineering, and industrial manufacturing. Currently, most widely used cable cutting equipment is semi-automatic.

[0003] The current procedure for cutting cables generally involves the operator manually lifting the cable to be cut into the positioning area of ​​the cutting machine stand, then supporting both ends of the cable with both hands to maintain its horizontal stability, and finally manually pressing down on the cutting machine handle to drive the blade to complete the cut. However, manually supporting the cable poses safety hazards: during the cutting process, the operator needs to hold the cable at close range to maintain its stability, especially when the cutting point is in the middle of the cable. The straight-line distance between the operator's fingers and the cutting blade is usually less than 20cm. The high-speed falling cutting blade is prone to causing work-related injuries due to cable rolling or operational errors, posing a serious safety risk. Although mechanical clamps (such as bolt clamps) are used, the clamping operation requires tightening the bolts separately, which takes a long time for each clamping. Disassembly also requires manual unlocking, adding extra non-cutting time. Especially for cables of different diameters, the clamp opening degree needs to be repeatedly adjusted, further affecting the cutting efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a cable cutting device for electrical engineering installation.

[0005] The technical solution of this utility model is as follows:

[0006] A cable cutting device for electrical engineering installation includes a base and a cutting machine body mounted thereon with an adjustable angle. The cutting machine body is hinged to the base via a rotating shaft. The upper end face of the base is provided with a clamping seat located on one side of the cutting blade of the cutting machine body. The clamping seat is provided with a through hole for passing through the cable in the horizontal direction. The length direction of the through hole is perpendicular to the vertical plane where the movement trajectory of the cutting machine body is located.

[0007] A clamping and anti-loosening unit is provided on one side of the through hole along its length. The clamping and anti-loosening unit includes a clamping plate, which is horizontally arranged. One end of the clamping plate is hinged to the side of the clamping seat away from the cutting blade, and the other end is elastically connected to the clamping seat through an elastic element.

[0008] To facilitate the clamping and anti-loosening unit in holding the cable inserted into the through hole, two clamping and anti-loosening units are provided, which are symmetrically arranged on both sides inside the through hole along the direction perpendicular to its length.

[0009] To prevent the cable from sliding back when it is threaded through the through hole, which would affect the cutting of the cable, the clamping plate is provided with multiple anti-loosening teeth on the side near the cutting blade. The anti-loosening teeth are arranged along the width direction of the clamping plate, are set perpendicular to the clamping plate, and the ends of the anti-loosening teeth are close to the inside of the through hole.

[0010] Preferably, the clamping seat has a mounting hole corresponding to the elastic element along the direction of the vertical through hole. The mounting hole communicates with the through hole, the elastic element is installed in the mounting hole, and the outer end of the elastic element is located outside the mounting hole.

[0011] Furthermore, the elastic element is a first compression spring.

[0012] To avoid the phenomenon that large-diameter cables cannot pass through the through hole due to excessive thickness of the elastic element and clamping plate, the maximum length of the elastic element is greater than the depth of the mounting hole, and the minimum length of the elastic element is not greater than the depth of the mounting hole. This ensures that the elastic element is located inside the mounting hole when compressed, reducing the impact of excessively extended elastic element on the installation of large-diameter cables.

[0013] The specific structure of the above-mentioned cutting machine body is as follows: the cutting machine body includes a main mounting base for mounting the cutting blade, a rotating shaft is located below the main mounting base, and an extension plate extends outward from the horizontal surface of the main mounting base along its upper end face. The extension plate is located above the clamping base.

[0014] The clamping seat has a vertical hole that communicates with the through hole in the vertical direction. A pressing rod that is elastically connected to the vertical hole passes through the hole, and the extension plate can abut against the upper end of the pressing rod.

[0015] To prevent the extension plate and main mounting base from failing to move the cutting disc downwards to cut the cable due to the excessive length of the pressing rod, an elongated hole corresponding to the pressing rod is provided on the extension plate. The width of the elongated hole is greater than the outer diameter of the pressing rod, and a matching elongated baffle is inserted into the elongated hole.

[0016] Preferably, the vertical distance between the clamping seat and the cutting blade is 5-30 cm.

[0017] The beneficial effects of this utility model are as follows:

[0018] A clamping seat for threading a cable is installed 5-30 cm away from one side of the cutting blade. The clamping seat contains clamping plates that can limit the cable on both sides. The two clamping plates can clamp the outside of the cable, which replaces the need for the operator to hold the cable close to the cutting blade when cutting the cable. It provides a safe working environment. The operator only needs to hold the cable away from the cutting blade by hand or use simple tools.

[0019] When cutting cables, the cables are usually placed on a base that is higher than the ground. When the cables are placed in the clamping seat, they may back out due to their own weight and height. In order to limit the position of the cables in conjunction with the clamping seat, the clamping plate inside the clamping seat is equipped with anti-loosening teeth. The anti-loosening teeth are hinged to the clamping seat and can rotate on one side. They can work with the elastic element to further clamp the outer surface of the cable, prevent the cable from backing out, and improve the cutting accuracy of the cutting blade.

[0020] The pressing rod can move downwards under the drive of the main mounting base and the extension plate, so that the extension plate and the cutting blade move downwards simultaneously. The extension plate can also drive the pressing rod downwards. While the cutting blade cuts the cable, the pressing rod moves downwards to further press down and fix the clamped cable. At the same time, in order to facilitate the cutting of cables with different outer diameters, the pressing rod is relatively long and may affect the downward movement of the cutting blade. Therefore, a detachable elongated baffle is set at the position of the pressing rod on the extension plate. The elongated baffle can be removed as needed, and the pressing rod is not used to press down and fix the cable temporarily. Attached Figure Description

Hinge shaft. Detailed Implementation

[0031] See Figure 1 , Figure 2 and Figure 3 As shown, a cable cutting device for electrical engineering installation includes a base 1 and a cutting machine body 2 mounted on the base 1 with an adjustable angle. The cutting machine body 2 is hinged to the base 1 via a pivot 3. The upper surface of the base 1 has a clamping seat 4 located on one side of the cutting blade 203 of the cutting machine body 2. The clamping seat 4 has a through hole 401 for passing cables along a horizontal direction, and the length direction of the through hole 401 is perpendicular to the vertical plane of the moving trajectory of the cutting machine body 2. The cutting machine body 2 is a semi-automatic cutting machine of the prior art, requiring a worker to move it downwards to cut the cables.

[0032] A clamping and anti-loosening unit is provided on one or both sides of the through hole 401 along its length. The clamping and anti-loosening unit includes a clamping plate 5, which is horizontally arranged. One end of the clamping plate 5 is hinged to the side of the clamping seat 4 away from the cutting plate 203, and the other end is elastically connected to the clamping seat 4 through an elastic member 6. To facilitate the clamping and anti-loosening unit in clamping the cable passing through the through hole 401, this embodiment provides two clamping and anti-loosening units, which are symmetrically arranged on both sides of the through hole 401 along its length.

[0033] The hinge connection between the clamping plate 5 and the clamping seat 4 is existing technology. The clamping plate 5 has a hinge shaft 12 on one side, and the clamping seat 4 has a hinge seat that is compatible with the hinge shaft 12. The hinge shaft 12 is vertically arranged.

[0034] The vertical distance between the clamping base 4 and the cutting blade 203 is 5-30 cm. A clamping base 4 for passing a cable is set at a position of 5-30 cm on one side of the cutting blade 203. The clamping base 4 is equipped with clamping plates 5 that can limit the cable on both sides. The two clamping plates 5 can clamp the outside of the cable, which replaces the need for the operator to hold the cable close to the cutting blade 203 when cutting the cable. It provides a safe working environment. The operator only needs to hold the cable away from the cutting blade 203 by hand or use simple tools.

[0035] See Figure 4 and Figure 5 As shown, in order to prevent the cable from sliding back when it is inserted into the through hole 401 and affecting the cutting of the cable, the clamping plate 5 is provided with a plurality of anti-loosening teeth 7 on the side near the cutting plate 203. The anti-loosening teeth 7 are arranged along the width direction of the clamping plate 5, and are perpendicular to the clamping plate 5. The ends of the anti-loosening teeth 7 are close to the inside of the through hole 401.

[0036] See Figure 5 , Figure 6 and Figure 7As shown, the clamping base 4 has a mounting hole 402 corresponding to the elastic element 6 along the direction perpendicular to the through hole 401. The mounting hole 402 communicates with the through hole 401, and the elastic element 6 is installed in the mounting hole 402, with the outer end of the elastic element 6 located outside the mounting hole 402. The elastic element 6 is a first compression spring. To avoid the phenomenon that large-diameter cables cannot pass through the through hole 401 due to the excessive thickness of the elastic element 6 and the clamping plate 5, the maximum length of the elastic element 6 is greater than the depth of the mounting hole 402, and the minimum length of the elastic element 6 is not greater than the depth of the mounting hole 402. This ensures that the elastic element 6 is located inside the mounting hole 402 when compressed, reducing the impact of the elastic element 6 extending too far on the passage of large-diameter cables.

[0037] The cutting machine body 2 is existing technology. After startup, the cutting operation can be achieved by manually controlling the position of the cutting blade 203. After cutting, the cutting blade 203 can be reset. The cutting machine body 2 includes a main mounting base 201 for supporting the cutting blade 203. The rotating shaft 3 is located below the main mounting base 201. An extension plate 202 extends outward from the horizontal surface of the main mounting base 201 along its upper end face. The extension plate 202 is located above the clamping base 4.

[0038] See Figure 4 and Figure 6 As shown, the clamping base 4 has a vertical hole 403 communicating with the through hole 401. A pressing rod 8 elastically connected to the vertical hole 403 passes through the vertical hole 403. The pressing rod 8 is elastically connected to the vertical hole 403 through a second compression spring 10. The second compression spring 10 is sleeved on the pressing rod 8, with its upper end located above the vertical hole 403. The upper end of the second compression spring 10 is connected to the upper part of the pressing rod 8, and its lower end is connected to the inner wall of the vertical hole 403. An arc-shaped plate 11 is connected to the lower end of the pressing rod 8, which contacts the surface of the cable, increasing the contact area.

[0039] The extension plate 202 can abut against the upper end of the pressing rod 8. The pressing rod 8 can move downward under the action of the main mounting base 201 and the extension plate 202, so that the extension plate 202 and the cutting blade 203 move downward at the same time. The extension plate 202 can also drive the pressing rod 8 to move downward. While the cutting blade 203 cuts the cable, the pressing rod 8 moves downward to further press down and fix the clamped cable. At the same time, in order to facilitate the cutting of cables with different outer diameters, the pressing rod 8 is relatively long and may affect the downward movement of the cutting blade 203. Therefore, a detachable elongated baffle 9 is set at the position of the extension plate 202 corresponding to the pressing rod 8. The elongated baffle 9 can be removed according to the actual situation, and the pressing rod 8 is not used to press down and fix the cable temporarily. Specifically, the extension plate 202 has an elongated hole 2021 corresponding to the pressing rod 8. The width of the elongated hole 2021 is greater than the outer diameter of the pressing rod 8. An elongated baffle 9 that is adapted to it is inserted into the elongated hole 2021.
