Description
Technical Field
[0001] The utility model relates to the technical field of wire harnesses for electric locomotives, in particular to a wire harness shearing device inside an electric locomotive. Background Art
[0002] An electric locomotive, also known as an electric train, is a railway locomotive that extracts electric power from the outside as an energy source for driving. It is a locomotive that does not carry its own energy. A wire harness is the overall equipment that provides services for a certain load source group, such as relay lines, switching devices, control systems, etc.
[0003] When the existing wire harness shearing device strips the wire harness, since the distance that the cutting tool extends into the outer layer of the wire harness cannot be controlled, the cutting tool will damage the copper wire inside the wire harness, making it inconvenient for workers to use tools to strip the wire harness. At the same time, when shearing, the cutting direction of the wire harness cannot be controlled, resulting in uneven horizontal degrees of the openings after the wire harness is cut, which is inconvenient for workers to connect the cut wire harnesses. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that there is a disadvantage in the prior art that it is inconvenient to strip the wire harness. For this reason, we propose a wire harness shearing device inside an electric locomotive.
[0005] In order to achieve the above object, the present application adopts the following technical solution: A wire harness shearing device inside an electric locomotive, including a mounting plate, a handle is fixedly connected to the bottom of the mounting plate, a static plate is fixedly connected to the top of the mounting plate, sliding grooves are opened on both sides of the mounting plate, a sliding rod is fixedly connected to the inner wall of the sliding groove, a slider is slidably connected to the surface of the sliding rod, a moving plate is fixedly connected to the top of the slider, cutting tools are fixedly connected to the opposite surfaces of the moving plate and the static plate, an extension block is fixedly connected to the top of the mounting plate, and an L-shaped threaded rod is threadedly connected to the inside of the extension block.
[0006] Preferably, a circular groove is opened inside the slider, several balls are slidably connected to the inner wall of the circular groove, and the surface of the balls is slidably connected to the surface of the sliding rod.
[0007] Preferably, a spring is fixedly connected to one side of the sliding rod, and the other end of the spring is fixedly connected to the inner wall of the sliding groove.
[0008] Preferably, the inner wall of the spring is slidably connected to the surface of the sliding rod.
[0009] Preferably, an extension rod is fixedly connected to one side of the L-shaped threaded rod, and a rotating shell is rotatably connected to the surface of the extension rod.
[0010] Preferably, a T-shaped groove is opened inside the mounting plate.
[0011] Preferably, a scale is fixedly connected to one side of the mounting plate.
[0012] The technical effects and advantages of the present utility model:
[0013] In the present utility model, the staff places the wire harness between the moving plate and the static plate. Through the threaded connection of the L-shaped threaded rod and the extension block, one end of the L-shaped threaded rod pushes the moving plate towards the static plate. The moving track of the moving plate is defined by the sliding of the slider on the surface of the sliding rod, so that the two cutting knives approach each other to cut the wire harness, realizing the cutting of relatively strong wire harnesses, saving the physical strength of the staff. At the same time, the cutting level of the cutting knife is perpendicular, which is convenient for the user to control the angle and size of the wire harness cutting. The staff can adjust the position of the cutting knife to pierce into the wire harness outer skin, which is convenient for the staff to strip the wire harness. Description of the Drawings

[0020] Now, with reference to the accompanying drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.
[0021] Refer to Figure 1 - Figure 5As shown in the figure, the utility model provides a technical solution: an internal wire harness shearing device for an electric locomotive, which includes a mounting plate 1. A handle 2 is fixedly connected to the bottom of the mounting plate 1. A static plate 3 is fixedly connected to the top of the mounting plate 1. Slide grooves 4 are opened on both sides of the mounting plate 1. A slide bar 5 is fixedly connected to the inner wall of the slide groove 4. A slider 6 is slidably connected to the surface of the slide bar 5. A moving plate 7 is fixedly connected to the top of the slider 6. Cutting knives 8 are fixedly connected to the opposite surfaces of the moving plate 7 and the static plate 3. An extension block 9 is fixedly connected to the top of the mounting plate 1. An L-shaped threaded rod 10 is threadedly connected to the inside of the extension block 9. By placing the wire harness between the moving plate 7 and the static plate 3 by the staff, through the threaded connection between the L-shaped threaded rod 10 and the extension block 9, one end of the L-shaped threaded rod 10 is pushed to move the moving plate 7 towards the static plate 3. By the slider 6 sliding on the surface of the slide bar 5 to define the moving track of the moving plate 7, the two cutting knives 8 are brought closer to cut the wire harness, realizing the cutting of relatively strong wire harnesses, saving the physical strength of the staff. At the same time, the cutting of the cutting knife 8 is horizontal and vertical, facilitating the user to control the angle and size of the wire harness cutting. By the staff, the position of the cutting knife 8 can be adjusted to pierce into the outer skin of the wire harness, facilitating the staff to strip the wire harness.
[0022] Referring to Figure 2 As shown in the figure, in this implementation scheme: a circular groove 11 is opened inside the slider 6. A number of balls 12 are slidably connected to the inner wall of the circular groove 11. The surface of the balls 12 is slidably connected to the surface of the slide bar 5. When the slider 6 moves on the surface of the slide bar 5, through the contact between a number of balls 12 rolling in the circular groove 11 and the surface of the slide bar 5, the contact area between the slider 6 and the slide bar 5 is reduced, and the frictional resistance generated by the slider 6 sliding on the surface of the slide bar 5 is reduced, improving the smoothness of the slider 6 movement.
[0023] Referring to Figure 4 As shown in the figure, in this implementation scheme: a spring 13 is fixedly connected to one side of the slide bar 5. The other end of the spring 13 is fixedly connected to the inner wall of the slide groove 4. When the moving plate 7 drives the slider 6 to move, the slider 6 pulls the spring 13 to extend and store energy. When the staff removes the restriction on the moving plate 7, the force generated by the spring 13 is released, and the spring 13 rebounds to pull the slider 6 to drive the moving plate 7 to reset, facilitating the staff to reset the position of the moving plate 7 so as to facilitate the staff to adjust the position of the moving plate 7 next time to use the cutting knife 8.
[0024] Referring to Figure 3 As shown in the figure, in this implementation scheme: the inner wall of the spring 13 is slidably connected to the surface of the slide bar 5. When the spring 13 rebounds, the spring 13 moves on the outside of the slide bar 5, preventing the spring 13 from curling and winding with each other when rebounding, thereby improving the stability of the component operation.
[0025] Referring to Figure 5As shown, in this implementation: One side of the L-shaped threaded rod 10 is fixedly connected with an extension rod 14. The surface of the extension rod 14 is rotatably connected with a rotating shell 15. By the staff tightly holding the rotating shell 15 by hand and making it perform a rotational movement on the surface of the extension rod 14, in this way, the staff can more easily turn the L-shaped threaded rod 10, and then effectively push the moving plate 7.
[0026] Refer to Figure 4 As shown, in this implementation: A T-shaped groove 16 is opened inside the mounting plate 1. Through the opened T-shaped groove 16, the waste generated by the cutting of the cutting knife 8 can fall through the T-shaped groove 16 on the other side, preventing the waste from accumulating in the static plate 3 and the moving plate 7 and causing blockage, which affects the normal operation of the cutting knife 8.
[0027] Refer to Figure 1 As shown, in this implementation: One side of the mounting plate 1 is fixedly connected with a scale 17. By setting the scale 17 on one side of the mounting plate 1, when the user operates the device to cut the wire harness, the user can measure according to the scale 17, so as to facilitate the staff to control the cutting distance of the wire harness.
[0028] Working principle: The staff places the wire harness between the moving plate 7 and the static plate 3. Through the threaded connection of the L-shaped threaded rod 10 and the extension block 9, one end of the L-shaped threaded rod 10 pushes the moving plate 7 towards the static plate 3. The moving track of the moving plate 7 is defined by the sliding of the slider 6 on the surface of the sliding rod 5, so that the two cutting knives 8 approach each other to cut the wire harness, realizing the cutting of relatively strong wire harnesses, saving the physical strength of the staff. At the same time, the cutting level of the cutting knife 8 is perpendicular, facilitating the user to control the angle and size of the wire harness cutting. The staff can adjust the position of the cutting knife 8 to pierce into the wire harness outer skin, facilitating the staff to strip the wire harness. When the slider 6 moves on the surface of the sliding rod 5, a number of balls 12 rolling in the circular groove 11 contact the surface of the sliding rod 5, reducing the contact area between the slider 6 and the sliding rod 5, reducing the frictional resistance generated by the sliding of the slider 6 on the surface of the sliding rod 5, and improving the smoothness of the slider 6 movement. When the moving plate 7 drives the slider 6 to move, the slider 6 pulls the spring 13 to extend and store energy. When the staff releases the restriction on the moving plate 7, the force generated by the spring 13's release rebounds to pull the slider 6 to drive the moving plate 7 to reset, facilitating the staff to reset the position of the moving plate 7 for the next adjustment of the moving plate 7's position to use the cutting knife 8. When the spring 13 rebounds, the spring 13 moves outside the sliding rod 5 to prevent the springs 13 from curling and winding around each other when rebounding, thereby improving the stability of the component operation. The staff tightly holds the rotating shell 15 by hand and makes it rotate on the surface of the extension rod 14. In this way, the staff can more easily turn the L-shaped threaded rod 10 component, and then effectively push the moving plate 7. The waste generated by the cutting of the cutting knife 8 falls through the opened T-shaped groove 16, preventing the waste from accumulating in the static plate 3 and the moving plate 7 and causing blockage, which affects the normal operation of the cutting knife 8. Through the scale 17 provided on one side of the mounting plate 1, when the user operates the device to cut the wire harness, it can be measured according to the scale 17, facilitating the staff to control the cutting distance of the wire harness.
