[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Example: Figure 1-4 As shown, this embodiment provides a railway wire stringing device, including a slide rail assembly 1, a sliding base 2, an arm assembly 3, a control system 4, a hydraulic system 5 and an electrical system 6.

[0026] The wire stringing device is installed on the top of the working vehicle body through the slide rail assembly 1, the sliding base 2 is installed in the slide rail assembly 1, and the sliding base 2 is driven by the sliding cylinder 21 to realize left and right sliding movement in the slide rail assembly 1.

[0027] The boom assembly 3 is hinged with the sliding base 2, and the boom assembly 3 is driven by the variable amplitude cylinder 24 to achieve pitch movement. At the same time, the boom assembly 3 can also achieve telescopic movement of the arm body through the telescopic cylinder 31; at the end of the boom assembly 3, a wire pulling pulley group 32 is also installed, and the wire is placed on the top of the wire pulling pulley group 32. Through sliding, variable amplitude and telescopic actions, the position of the tension contact wire and the load-bearing cable can be accurately adjusted; in the retracted state, the hook plate 11 on the slide rail assembly 1 can also lock the boom assembly 3 to prevent the boom assembly 3 from moving during driving, ensuring that the device is safer and more reliable during driving; at the same time, the boom assembly 3 has a negative angle in the retracted state (that is, the arm head of the boom assembly 3 is lower than the arm tail), which makes the retracted size of the device smaller and the volume smaller, and it is safer to drive within the railway limit range. At the same time, the telescopic length can be made longer and the performance parameters are better.

[0028] The operating system 4 is used to manually control the movement of each action of the device.

[0029] The hydraulic system 5 provides power for the sliding cylinder 21, the luffing cylinder 24, and the telescopic cylinder 31 to realize sliding, luffing and telescopic actions. The operating range is wide, and each action can be controlled to be reliably braked and maintained at any position, ensuring that the device is safer and more reliable during operation.

[0030] The electrical system 6 can realize the functions of the device such as the neutral position detection, locking position detection, manual and remote control mode switching, emergency braking and lighting, and can also realize the remote control operation of the device, making the operation of the device more convenient and simple, and the operation safer and more efficient.

[0031] The stringing device is also provided with a remote controller, a signal transmitting end of the remote controller is wirelessly connected to the work vehicle controller, a signal end of the operating system 4 is connected to a signal control end of the work vehicle controller, and the operating system is used for manual control of the stringing device. The stringing device has both manual and remote control control modes, which makes the operation more convenient.

[0032] like Figure 3 and Figure 4 As shown, the sliding base 2 is mainly composed of a sliding oil cylinder 21, a base body 22, a roller 23 and a variable amplitude oil cylinder 24. The rollers 23 are installed on both sides of the base body 22, and the sliding base 2 is driven to roll in the slide rail by the sliding oil cylinder 21. Compared with sliding friction, the rolling friction coefficient is lower, the load force during movement is smaller, and the corresponding required oil cylinder specifications are also smaller, with low cost and low energy consumption.

[0033] In summary, the wire-laying device is installed on the top of the work vehicle body, and the arm assembly 3 is staggered. In addition to its own amplitude change and telescopic actions, it can also slide horizontally on the slide rail. Each action can be reliably braked and maintained at any position, so the working range is wide and the operation is safe and reliable.

[0034] The wire-string device has functions such as mid-position detection, locking position detection, switching between manual and remote control operation modes, emergency braking, lighting, etc. It has both manual and remote control operation modes, so the operation is more convenient and simple, and the operation is safer and more efficient.

[0035] The boom assembly 3 has a negative angle in the retracted state (i.e., the boom head of the boom assembly is lower than the boom tail), which makes the retracted size of the device smaller and the volume smaller, so it is safer to drive within the railway limit range. At the same time, the telescopic length can be made longer and the performance parameters are better.

[0036] Rollers 23 are installed on both sides of the sliding base 2. The sliding process is rolling friction, and the rolling friction coefficient is lower. Therefore, the load force during the movement is smaller, and the corresponding required cylinder specifications are also smaller, with low cost and low energy consumption.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
