Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 4 As shown, the walking mechanism suitable for pipeline installation equipment of the present invention includes a chassis front section 1, a chassis middle section 2, a chassis rear section 3, a hydraulic cylinder 6, a track moving component 7 and a flat ground moving component 8, wherein: the chassis front section 1 can be rotatably arranged at the front end of the chassis middle section 2, the chassis rear section 3 can be rotatably arranged at the rear end of the chassis middle section 2, the hydraulic cylinder 6 is respectively arranged between the chassis front section 1 and the chassis middle section 2, and between the chassis rear section 3 and the chassis middle section 2, for providing power for the rotation of the chassis front section 1 and the chassis rear section 3, the track moving components 7 are respectively symmetrically arranged on the chassis front section 1 and the chassis rear section 3, for moving along the track, and the flat ground moving components 8 are symmetrically arranged on the chassis middle section 2, for moving on the ground.

[0028] Furthermore, in the traveling mechanism of the present invention suitable for pipeline installation equipment, a mounting platform 21 is arranged in a rectangular shape on the middle section 2 of the chassis, a first rotating hole 22 is arranged on the mounting platform 21, and a first positioning hole 23 is arranged on one side of the mounting platform 21 close to the first rotating hole 22.

[0029] Furthermore, in the walking mechanism suitable for pipeline installation equipment of the present invention, turntables 4 are symmetrically arranged at both ends of the chassis front section 1 and the chassis rear section 3, and a second rotating hole 41 is arranged on the turntable 4. The second rotating hole 41 is connected to the first rotating hole 22 through a hinge shaft, and a second positioning hole 42 is arranged on the side of the turntable 4 close to the second rotating hole 41, thereby effectively ensuring that the chassis front section 1 and the chassis rear section 3 can rotate, thereby realizing the interchange of the two moving modes of the track moving component 7 on the track and the flat moving component 8 on the flat ground, transporting and installing the pipeline, and improving the transfer efficiency.

[0030] Furthermore, in the walking mechanism suitable for pipeline installation equipment of the present invention, a positioning pin 43 is slidably provided on the second positioning hole 42, and the positioning pin 43 matches the first positioning hole 23. The turntable 4 and the mounting table 21 are positioned by the positioning pin 43, thereby ensuring stability when performing the track movement mode and avoiding the hydraulic cylinder 6 from being subjected to load when moving on the track.

[0031] Furthermore, in the walking mechanism suitable for pipeline installation equipment of the present invention, first connecting plates 24 are symmetrically welded at both ends of the middle part of the middle section 2 of the chassis, second connecting plates 5 are welded in the middle of the front section 1 of the chassis and the rear section 3 of the chassis, the mounting end of the hydraulic cylinder 6 is hingedly connected to the first connecting plate 24, and the output end of the hydraulic cylinder 6 is hingedly connected to the second connecting plate 5, thereby providing driving force for the lifting and lowering of the front section 1 of the chassis and the rear section 3 of the chassis.

[0032] Furthermore, in the walking mechanism suitable for pipeline installation equipment of the present invention, the track moving assembly 7 includes a track wheel 71 and a drive motor 72. The track wheel 71 can be rotatably installed on both ends of the chassis front section 1 and the chassis rear section 3 respectively. The drive motor 72 is fixedly connected to the chassis front section 1 and the chassis rear section 3 respectively by bolts. The track wheel 71 is connected to the output end shaft of the drive motor 72, thereby effectively ensuring that after the track wheel 71 contacts the track, it can move along the track through the drive motor 72.

[0033] Furthermore, in the walking mechanism suitable for pipeline installation equipment of the present invention, the flat ground moving component 8 includes a flat ground rubber wheel 81 and a hub motor 82, the hub motor 82 is fixedly connected to the middle section 2 of the chassis, and the flat ground rubber wheel 81 is fixedly connected to the output shaft of the hub motor 82, thereby effectively ensuring that after the flat ground rubber wheel 81 contacts the ground, the hub motor 82 can drive the flat ground rubber wheel 81 to move on the ground.

[0034] Specifically, when moving on the track, Figure 1As shown, the hydraulic cylinder 6 is in a retracted state, and the positioning pin 43 is slidably inserted into the first positioning hole 23 in the second positioning hole 42, so as to prevent the hydraulic cylinders 6 at both ends from bearing loads when the track is moving, so that the front section 1 of the chassis, the rear section 3 of the chassis and the middle section 2 of the chassis are evenly loaded during the installation of the equipment, and the bearing capacity of the chassis is increased. At this time, the front section 1 of the chassis and the rear section 3 of the chassis are flush with the middle section 2 of the chassis, and the track wheel 71 is in contact with the track. The driving motor 72 provides power to drive the track wheel 71 to rotate, so that the equipment can move on the double track, and at the same time, it has a high positioning accuracy, so as to realize the fast and convenient transportation and installation of the pipeline installation equipment;

[0035] When moving on flat ground, Figure 3 As shown, the positioning pin 43 is pulled out of the first positioning hole 23, and the hydraulic cylinder 6 is operated to extend. At this time, the front section 1 of the chassis and the rear section 3 of the chassis are lifted up at the same time, the track wheel 71 leaves the track, and the leveling rubber wheel 81 touches the ground. The hub motor 82 provides power to drive the leveling rubber wheel 81 to rotate, so that the walking mechanism can walk on and off the track and on the ground. The leveling rubber wheel 81 will not damage the flat ground, and is suitable for non-track sections on the construction site.

[0036] In summary, compared with the prior art, the walking mechanism of the present invention suitable for pipeline installation equipment has the following advantages and beneficial effects:
