Detailed Description

In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 5, an endless track with an elastic cushion member includes: the track single sheet 1 and an elastic cushion member 2 fixed on the track single sheet 1;

the number of the track single sheets 1 is one or more, and the track single sheets are connected end to end and surround the pipeline.

When the number of the track single sheets 1 is multiple, preferably, four single sheets are selected for splicing, the number of the track single sheets 1 is four, and each track single sheet 1 is 90 degrees. The track single sheets 1 are spliced into a ring shape and sleeved on the pipeline 5; when the number of the track single sheets 1 is larger, the time for splicing is increased, the assembly efficiency is reduced, and joints are formed at the joints of every two single sheets to cause vibration of the welding walking machine, so that the track joints are reduced as much as possible in the aspect of design.

When the number of the track single sheets 1 is one, the track single sheets directly surround the pipeline. The end to end of the welding trolley is fixed through the connecting piece, and the purpose is that only one seam is reserved, so that the running stability of the welding trolley on the track is improved.

Furthermore, the splicing positions of every two adjacent annular tracks are connected through a connecting piece 3; the connecting piece 3 comprises a fixed block 301 and a threaded screw 302 which are respectively arranged at two ends of the track single piece 1; after the two single rails 1 are abutted, the two fixing blocks 301 are fixed by the threaded screws 302. The threaded screw 302 passes through the two fixing blocks 301 and plays a fixing role.

Furthermore, the elastic cushion pieces 2 are uniformly distributed below the track single pieces 1 at equal intervals, and the elastic cushion pieces 2 are assembled and sleeved on the telescopic column 201 through a plurality of elastic single pieces 4 and supported on the track single pieces 1; every two elastic single sheets 4 are in a group and are fixedly arranged below the track single sheet 1 in parallel. The telescopic column 201 of the elastic cushion part 2 comprises a female end 203 with a column body and a sub end 202 sleeved on the column body; the elastic single sheet 4 is sleeved on the column body, and the front and the rear of the column body are respectively provided with a stud 204 to fix the track single sheet. The elastic single sheets 4 are annular and have conicity, and every two elastic single sheets 4 are symmetrically buckled and sleeved on the column body. The two elastic single pieces form an annular flying saucer-shaped appearance, and when the two elastic single pieces are stressed and extruded, the two elastic single pieces approach each other, namely the flying saucer-shaped appearance is gradually flattened.

The studs at the front and the rear of the column body are respectively used for being fixed on the pipeline and the track single sheet. The acceptance degree of the elastic cushion piece is adjusted through the tightness degree of the stud, so that the whole annular track is matched with the shape of the pipeline.

Further, the surface of the track single sheet 1 is provided with strip-shaped holes 101 which are uniformly distributed. The strip-shaped hole 101 is fitted to an external welding mechanism.

Further, a gasket is arranged between the elastic cushion piece and the rail single piece. The elastic cushion piece is prevented from being rigidly connected with the track single piece, and meanwhile, the friction force of the bolt and the elastic cushion piece is increased. The method of adding the gasket with a certain thickness on the elastic cushion piece is achieved, so that the track can be used on pipelines with and without anticorrosive coatings.

The working principle of the device is as follows:

the track single sheets are sleeved on the pipeline, one or more single sheets are fixed into an annular track through the threaded screw and the fixing block, and the annular track is matched with the shape of the pipeline through adjusting the stud of the elastic cushion piece.

Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
