Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0028] Currently, when prefabricating contact wires for overhead contact systems, the contact wires are typically cut to a predetermined length first, and then the ends of the contact wires are individually fitted with dropper clamps. This prefabrication method is inefficient. To address the above problems, this utility model provides a prefabrication platform device for overhead contact system droppers.

[0029] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0030] This utility model discloses a prefabrication platform device for contact wire droppers, referring to... Figure 1 and Figure 2 As shown, it includes a workbench 1, a pressing component 2, and a cutting component 3.

[0031] The pressing component 2 is connected to the worktable 1. The pressing component 2 includes two pressing blocks 21. A pressing rod 22 is provided on one side of the pressing block 21. The pressing rod 22 is used to drive the two pressing blocks 21 to move closer to each other. The cutting component 3 is connected to the worktable 1. The cutting component 3 is used to cut the contact line.

[0032] When the device is working, the contact wire is passed through the cutting piece 3, so that one end of the contact wire is located between the two pressing blocks 21. The cutting piece 3 cuts the contact wire according to the preset contact wire length. After the cutting is completed, the dropper wire clamp is put on the end of the contact wire, so that the end of the contact wire and the dropper wire clamp are located between the two pressing blocks 21. Then, the pressing rod 22 is pushed to bring the two pressing blocks 21 closer to each other until the dropper wire clamp is fixed at the end of the contact wire, thus completing the prefabrication of the contact wire. Through the pressing piece 2 and the cutting piece 3 set on the surface of the workbench 1, the cutting and pressing of the contact wire is completed in one go, thereby improving the prefabrication efficiency of the contact wire.

[0033] In this embodiment, the surface of the workbench 1 is provided with two pressing parts 2 and a hanging part. When the contact wire is cut, the contact wire is fixed by the pressing parts 2. In other embodiments, the workbench 1 can be connected to other fixing devices to fix the contact wire.

[0034] In a preferred embodiment, refer to Figure 1 and Figure 3 The pressing rod 22 is slidably connected to a first precast seat 23, which is connected to the worktable 1. A push rod 24 is hinged to the side of the pressing rod 22 away from the pressing block 21. A movable rod 25 is hinged to the push rod 24, which is also hinged to the first precast seat 23. When the two pressing blocks 21 are brought closer together, pressing the push rod 24 causes the pressing rod 22 to slide, which in turn causes the pressing blocks 21 to slide, thus bringing the two pressing blocks 21 closer together; when the two pressing blocks 21 are moved further apart... When the device is removed, push rod 24 moves in the opposite direction, which drives pressing rod 22 to slide. Pressing rod 22 then drives pressing block 21 to slide, causing the two pressing blocks 21 to move away from each other. Workers can move pressing rod 22 by pushing rod 24, which improves work efficiency to a certain extent. Pressing block 21 is detachably connected to prefabricated seat. When the contact wire specifications change, different specifications of pressing block 21 can be replaced to quickly adapt to different specifications of contact wire, thereby increasing the application scenarios of the device.

[0035] In a preferred embodiment, refer to Figure 1 and Figure 4 The cutting component 3 includes a second preform 31, which is connected to the worktable 1. A first blade 32 is connected to the side of the second preform 31 away from the worktable 1. A second blade 33 is hinged to the first blade 32. When cutting the contact line, the contact line is passed through the gap between the first blade 32 and the second blade 33, and then the second blade 33 is pressed to cut the contact line.

[0036] In a preferred embodiment, refer to Figure 3 and Figure 4The first prefabrication base 23 has a sliding groove 26 that matches the worktable 1 on the side facing the worktable 1. The second prefabrication base 31 also has a sliding groove 26 that matches the worktable 1 on the side facing the worktable 1. The sliding groove 26 allows the pressing part 2 and the cutting part 3 to slide on the worktable 1, thereby enhancing the flexibility of the device.

[0037] In a preferred embodiment, refer to Figure 3 and Figure 4 The first prefabricated base 23 has a threaded hole 27 on the side facing away from the worktable 1, and a screw 28 passes through the threaded hole 27. The second prefabricated base 31 also has a threaded hole 27 on the side facing away from the worktable 1, and a screw 28 passes through the threaded hole 27. When fixing the first prefabricated base 23 or the second prefabricated base 31, the screw 28 is rotated so that one end of the screw 28 abuts against the worktable 1, thereby fixing the press-fit part 2 or the cut part 3. When adjusting the position of the first prefabricated base 23 or the second prefabricated base 31, the screw 28 is rotated in the opposite direction, thereby releasing the fixing of the press-fit part 2 or the cut part 3, so that the press-fit part 2 or the cut part 3 can slide relative to the worktable 1.

[0038] In a preferred embodiment, refer to Figure 3 and Figure 4 A scale 4 is connected to the outer wall of the workbench 1 facing the cutting part 3.
