[0022] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0023] like Figure 1 and Figure 2 The auxiliary device for manual laying of contact wire shown includes a flatbed cart 1, a laying frame mounted on the flatbed cart 1, and a catenary contact wire reel 20 detachably mounted on the laying frame. The laying frame includes two symmetrically arranged support frames. The support frames are equipped with height-adjustable support plates 11 via an adjustment mechanism. A lifting plate 13 is mounted above the support plates 11 via a lifting mechanism 19. The outer end of the support shaft 21 of the reel 20 is mounted on the lifting plate 13.

[0024] like Figure 3 As shown, in this embodiment, the support frame includes two vertically arranged guide columns 6. The adjustment mechanism includes multiple positioning holes 8 opened along the length direction on the guide columns 6 and a positioning pin 9 corresponding to the positioning holes 8. The two ends of the support plate 11 are sleeved on the guide columns 6 through guide sleeves 10, and the guide sleeves 10 are positioned by the positioning pins 9 inserted into the positioning holes 8. The two ends of the lifting plate 13 are sleeved on the guide columns 6 through lifting sleeves 12. The lifting mechanism 19 is a jack or hydraulic cylinder set on the support plate 11. When the lifting mechanism 19 is a hydraulic cylinder, a hydraulic pump also needs to be set on the flatbed trolley 1. Since the lifting height of the lifting plate 13 is limited, it is better to use a jack and operate it manually from the perspective of economic cost and convenience.

[0025] The auxiliary device for manual laying of contact wire provided by this utility model consists of a flatbed cart 1 and two detachable support frames installed on the left and right sides of its top. It has a simple structure and is convenient and flexible to use. It assists manual laying operations. In the construction of replacing the conductor of the existing contact wire, the device can wait at the construction site in advance. After the track closure order is issued, the device can be manually lifted onto the railway track for laying operations, which greatly reduces mechanical costs and improves construction efficiency.

[0026] The support plate 11 is supported by two positioning pins 9 on the same support frame under gravity. In use, the positions of the positioning pins 9 in the positioning holes 8 are adjusted according to the radius of the spool 20. When the lifting mechanism 19 is in the retracted state, after the spool 20 is placed on the flatbed trolley 1, its support shaft 21 is higher than the lifting plate 13. When the lifting mechanism 19 drives the lifting plate 13 to rise, the lifting plate 13 can lift the spool 20 off the upper surface of the flatbed trolley 1 via the support shaft 21, thus allowing for manual wire feeding. The adjustment mechanism includes multiple positioning holes 8 of different heights, therefore the height of the support plate 11 is adjustable, making it suitable for feeding spools 20 of different sizes.

[0027] As a further optimization, the support frame also includes a horizontally arranged base frame 5, with the guide column 6 fixed inside the base frame 5. Multiple wheels 16 are mounted on the outer end of the base frame 5 via a mounting bracket 15, and the mounting bracket 15 and wheels 16 are located above the outer end of the base frame 5. Multiple mounting plates 2 are fixedly mounted on the upper surface of the flatbed trolley 1, and the base frame 5 is detachably fixed to the mounting plates 2 by bolts or wires. Since the support frame is detachable, the wheels 16 are provided to facilitate manual pushing and transportation after the support frame is laid down.

[0028] As a further optimization, to enhance the structural strength and stability of the support frame, the support frame also includes a connecting plate 17 connected to the top of the two guide columns 6, and a plurality of support columns 7 are provided between the base frame 5 and the end of the connecting plate 17. Specifically, two support columns 7 are provided at the same end of the base frame 5 and the connecting plate 17, and a reinforcing plate 18 is connected between the two support columns 7.

[0029] As a further optimization, an arc-shaped groove 14 corresponding to the support shaft 21 is provided in the middle of the upper surface of the lifting plate 13. Under the action of gravity of the coil 20, the position of the support shaft 21 can be limited to prevent it from moving back and forth along the upper surface of the lifting plate 13.

[0030] The flatbed cart 1 is equipped with wheels 3 at its bottom, corresponding to the rails. The flatbed cart 1 also includes a drive motor 4 for rotating the wheels 3, a transmission mechanism, and a battery for supplying power to the drive motor 4. The transmission mechanism is a drive shaft, and the drive motor 4 is a geared motor whose output shaft is connected to the wheels 3 via the drive shaft. Furthermore, a controller is included to control the speed and direction of rotation of the drive motor 4.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
