As shown in fig. 1-3, a walking device for a self-adaptive wire and a compression joint pipe comprises a structural support 1 and a walking wheel set arranged on the structural support 1, wherein the walking wheel set comprises a walking wheel support 5, a walking wheel spring 4 and a walking wheel 2; the walking wheel 2 is arranged on the walking wheel bracket 5, the walking wheel bracket 5 is elastically connected with the structural bracket 1 through the walking wheel spring 4, and the elastic displacement of the walking wheel 2 is realized through the extension and retraction of the walking wheel spring 4, so that the walking wheel 2 is automatically adapted to the size change of the pressure connection pipe 7 and the lead 6.

The structure support 1 is a door-shaped mechanism and comprises two mounting supports 3 for mounting a walking wheel set and a connecting support for connecting the two mounting supports 3. One end of the travelling wheel bracket 5 is rotatably connected with the mounting bracket 3, and the travelling wheel 2 is mounted at the other end; the walking wheel spring 4 is installed in the middle of the walking wheel support 5, one end of the walking wheel spring 4 is connected with the walking wheel support 5, the other end of the walking wheel spring 4 is connected with the mounting support 3, the walking wheel 2 adapts to the change of the sizes of the crimping pipe 7 and the lead 6 through the rotation of the walking wheel support 5, and the walking wheel spring 4 is pressed and stuck on the crimping pipe 7 or the lead 6.

The number of the traveling wheel sets is 2 along the circumferential direction of the lead 6, the traveling wheel sets are arranged up and down, the outline of the traveling wheel sets 2 is V-shaped, and the lead 6 is clamped in the middle; the running wheel sets are also arranged with 2 running wheel sets along the length direction of the lead 6.

When the walking device of the self-adaptive wire and the pressure connection pipe normally runs on the wire 6, the walking wheels 2 on two sides of the wire 6 are tightly attached to the wire 6. When crossing the pressure connection pipe 7, the travelling wheel 2 at one side close to the pressure connection pipe 7 is compressed after being subjected to outward extrusion force due to the dimensional change, so that the travelling wheel 2 is jacked up and clings to the pressure connection pipe 7 to adapt to the dimensional change of the pressure connection pipe 7; when the traveling wheel 2 on the other side is close to the pressure connection pipe 7, the traveling wheel 2 is also subjected to outward extrusion force, and the traveling wheel bracket 5 is pushed to rotate, so that the traveling wheel 2 is adapted to the size of the pressure connection pipe 7; when the travelling device leaves the crimping pipe 7, the clamping size is reduced and the travelling wheel spring 4 is restored to the size of the lead 6, so that the stress of the travelling wheel spring 4 is gradually reduced, and the travelling wheel 2 is driven to restore to be in close fit with the lead 6.

Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present utility model, which is intended to be covered by the claims of the present utility model.
