[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 5 As shown, this utility model provides an existing railway line crossing frame for overhead line relocation construction, including a raised box 1 and a fixed plate 2. A motor 3 is fixedly connected to the rear side of the fixed plate 2. A first lead screw 4 is rotatably connected to the output end of the motor 3. A channel plate 5 is sleeved on the outer side of the first lead screw 4. Several sets of sliding grooves are opened inside the channel plate 5 to assist sliding. Then, a fixed frame 9 is rotatably connected to the other end of the first lead screw 4. The second fixed frame 9 is used to support the first lead screw 4. Then, the top of the fixed frame 9 is fixedly connected to the top of the supporting anti-conductive plate 19. The top of the channel plate 5 is opened with a sliding groove, and the inside of the sliding groove of the channel plate 5 is slidably connected. There is a fixed rod 6, and a first sliding rod 7 is fixedly connected to the bottom end of the fixed rod 6. When it is necessary to clamp the wire harness 12, the first groove plate 5 moves forward and outward from the fixed rod 6. The sliding cylinder 17 has a threaded groove inside. A threaded rod 11 is connected inside the threaded groove of the first sliding rod 7. A handle 10 is fixedly connected to the outside of the threaded rod 11. A clamp 13 is fixedly connected to the other end of the threaded rod 11. When the threaded rod 11 slides to the right, it drives the clamp 13 to move. A second sliding rod 14 is fixedly connected to the outside of another set of clamps 13. The outside of the second sliding rod 14 is slidably set at the front end of the fixed plate 2.
[0024] Specifically, a groove is provided at the top of the fixed plate 2, and a slider 8 is slidably connected inside the groove of the fixed plate 2. The top of the slider 8 is fixedly connected to the bottom of the first sliding rod 7, and the first sliding rod 7 and the second sliding rod 14 slide at equal distances at the top of the fixed plate 2.
[0025] Furthermore, a drive source 15 is fixedly connected inside the elevated box 1. The output end of the drive source 15 drives the second lead screw 16 to be helically connected to the sliding cylinder 17. When the sliding cylinder 17 slides upward, it drives the supporting anti-conductive plate 19 to move upward. A sleeve 18 is sleeved on the outside of the sliding cylinder 17 to protect the second lead screw 16, prevent dust from entering, and prevent the second lead screw 16 from tipping over during high-altitude operations. The bottom end of the sleeve 18 is fixedly connected to the top end of the support plate 21 for support.
[0026] Furthermore, a hydraulic rod 20 is fixedly connected to the bottom end of the support anti-conductive plate 19. The hydraulic rod 20 is used to assist the support anti-conductive plate 19 in sliding upward. A support plate 21 is fixedly connected to the bottom end of the hydraulic rod 20. A drive gear 22 is fixedly connected to the bottom end of the support plate 21. A driven gear 23 is meshed and rotatably connected to the outer side of the drive gear 22. When the support plate 21 rotates, it drives the drive gear 22 to rotate, and the drive gear 22 drives the driven gear 23 to rotate.
[0027] It is worth noting that the bottom of the driven gear 23 is fixedly connected to the top of the jacking box 1 at its internal center position. When the driven gear 23 rotates, it drives the support plate 21 to rotate at the top of the jacking box 1, which facilitates the adjustment of the wire harness 12.
[0028] It is worth noting that there are two sets of clamps 13, and wire harnesses 12 are tightly fitted inside the two sets of clamps 13, with the wire harnesses 12 being secured inside the clamps 13.
[0029] It is worth mentioning that the first sliding rod 7 is provided in several sets. Two adjacent sets of the first sliding rod 7 are used to clamp the wire harness 12 to be moved and to move the wire harness 12 later. They are symmetrically arranged at the top of the fixing plate 2. The grooved plate 5 slides back and forth at the top of the fixing plate 2. When the grooved plate 5 slides towards the front end inside the fixing rod 6, the first sliding rod 7 moves towards the center position.
[0030] Among them, motor 3 and drive source 15 are existing technologies and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.
[0031] Working principle:
[0032] First, the staff places the elevated box 1 at the bottom of the area where the wire harness 12 needs to be moved, and fixes the bottom of the elevated box 1 to the flat ground. Then, according to the height of the wire harness 12, the drive source 15 inside the elevated box 1 is activated. The drive source 15 drives the second lead screw 16 to rotate clockwise. The second lead screw 16 engages with the outer sliding cylinder 17 and slides upward. The sliding cylinder 17 pushes the top support anti-conductive plate 19 upward, bringing the first sliding rod 7 into contact with the outer wire harness 12. Next, the motor 3 is activated. The motor 3 rotates clockwise, driving the first lead screw 4 to rotate. The outer grooved plate 5 slides backward on the top of the fixed plate 2. The grooved plate 5 slides backward on the outside of the fixed rod 6. During the sliding process, the first sliding rod 7 slides backward. The first sliding rod 7 and the second sliding rod 14 move closer to the center position. When they move to the point where they can no longer fit with the wire harness 12, the handle 10 is rotated to drive the threaded rod 11 to rotate. The threaded rod 11 drives the clamp 13 to push the wire harness 12 to the right side and fix it inside the clamp 13 that is fixedly welded to the second sliding rod 14. After all the remaining wire harnesses 12 are fixed, the raised box 1 is moved to a new position.
