The wheel surface of the walking wheel 4 is arranged in a V shape or a U shape capable of clamping the supporting steel cable. Preferably, a groove is arranged on the supporting portion 21, and the walking wheel 4 is supported in the groove through a rotating shaft and is fixed through a bolt. Further, the traction hooks 5 are used to connect with the workers when the device is hung and walked, and the number and installation position of the traction hooks can be arranged according to the needs. As an embodiment, as shown in the figure, the traction hooks 5 comprise a traction hook arranged at the upper cross beam 1 for suspension, traction hooks arranged at the two ends of the frame body for forward and backward movement, and traction hooks arranged at the bottom of the frame body for traction and direction control. Specifically, the traction hook 5 is in a U shape and is connected with the frame body by welding.

[0027] The threading mechanism of the present application comprises a threading pin 6 and at least two groups of clamping arm assemblies capable of clamping the threading pin 6. Each group of clamping arm assemblies comprises a pair of clamping jaws 7 arranged on the two sides of the threading pin 6, and the pair of clamping jaws 7 are clamped or released from the threading pin 6 under the driving of the driving device. The driving device is connected with the frame body through a clamping support. Further, the driving device comprises a controller 8 and an electric push rod 9. The clamping support comprises a lower cross beam 10 horizontally arranged between the two side supporting frames 2, and a mounting frame 11 arranged below the lower cross beam 10. The driving device is mounted on the mounting frame 11. The inner middle part of the clamping jaw 7 is hinged with the lower cross beam 10, forming a lever-like structure. The free end of each electric push rod 9 is connected with the clamping jaw 7 on the two sides through two connecting plates 12. The controller controls the extension and retraction of the electric push rod, when the electric push rod goes up, the distance between the top end of the electric push rod and the hinge joint of the clamping jaw decreases, the included angle between the two connecting plates increases, the bottom of the two clamping jaws opens, and the upper end closes to clamp the threading pin; when the electric push rod goes down, the distance between the top end of the electric push rod and the hinge joint of the clamping jaw increases, the included angle between the two connecting plates decreases, the bottom of the two clamping jaws closes, and the upper end opens to release the threading pin. Further, each clamping arm assembly further comprises a travel switch 13 electrically connected with the controller 8. The travel switch 13 can be mounted on the lower cross beam 10 or the positive sliding skid 14 through a support. The travel switch 13 can identify the position of the hook 17 on the supporting steel cable 15, so that when it runs to the position of the hook 17, the corresponding clamping jaw 17 is opened, so that the cable can pass through smoothly.

[0028] Further, the number of clamping arm assemblies is at least two groups, only need to ensure that always at least a group of clamping arm assemblies clamping through the pin, can. As shown, the embodiment with two groups of clamping arm assemblies. In the process of device running, the hook 17 from front to back through the pin 6. Clamping arm assembly clamping pin 6 to play a supporting role to the pin 6, in order to be able to smoothly through the hook 17, avoid collision, two groups of clamping arm assembly under the control of the travel switch 13 open one by one. Corresponding to the hook 17 position of a pair of clamping jaw 7 loose pin 6, so that it smoothly through the hook 17, the other pair of clamping jaw 7 clamping pin 6, support pin 6 from the device off. The device continues to run, the working state of two groups of clamping arm assembly is adjusted, so as to complete a wiring process. Similarly, those skilled in the art can set multiple groups of clamping arm assembly according to the need, only the corresponding hook position of the clamping jaw loose, the rest of the position of the clamping jaw can be kept in clamping state.

[0029] Further, the frame body further comprises a positioning skid 4 arranged below the upper cross beam 1. The positioning skid 4 is composed of two parallel arranged pry bars connected with the frame body. The two ends of the pry bar are tilted upward. The two pry bars of the positioning skid 4 are located on both sides of the supporting steel cable, and the main body of the pry bar is located below the supporting steel cable. During the running of the frame body, the tilted parts at the two ends of the pry bar can limit the supporting steel cable to pass between the two bar bodies. When the frame body is tilted, the lower pry bar will abut against the hook to correct the position and assist in maintaining the perpendicularity between the device and the hook.

[0030] Further, a circular recess 18 is arranged on the pin 6; and an arc-shaped groove 19 is arranged on the inner side of the clamping jaw 7, which is matched with the circular recess 18.

[0031] Further, the present application also sets up a wire arranging device. In actual work process, the hook 17 has been hung with several cables, and the subsequent threading will cause winding with the previous cable and other situations, resulting in threading failure. Therefore, the function of the wire arranging device is to arrange in front of the threading mechanism, clamp the existing cable and then pull it down to leave a threading space. The wire arranging device of the present application comprises an electric push rod and a pair of wire arranging clamps 20 arranged on the top of the electric push rod. The upper ends of the two wire arranging clamps 20 can be opened or crossed, and the middle part is hinged to the lower cross beam. The working principle is the same as that of the clamping arm. When the electric push rod goes up, the two wire arranging clamps 20 clamp the existing cable and cross it to press the internal cable down to leave a threading space. When meeting the hook 17, the wire arranging clamps 20 are opened to make the hook pass through.

[0032] The working principle of the application is as follows: the whole is placed above the overhead steel cable by hanging the traction hooks on the upper hand-held long rod, and the safety buckle is locked to prevent unhooking. The whole is driven to move forward and backward by pulling the traction hooks on both sides to drive the traction hooks below to control the traction and direction. The equipment is ensured to run safely by the positioning skid. When the equipment works, the power is transmitted through the traction hooks, the position of the hooks is recognized by the travel switch, the optical cable is pulled through the hooks by the two groups of clamping mechanisms alternately clamping the threading pin, and the wire arrangement device is responsible for the wire arrangement before clamping to ensure that there is no mistake and damage to the original cable.

[0033] The application is convenient to operate, and the personnel only need to pull on the ground to realize the laying of the optical cable. The setting of the threading mechanism enables the device to automatically pass through the hooks and run stably, which greatly saves manpower and resources.

[0034] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the application, and not to limit them; although the application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the application examples.
