Abstract
Description
Technical Field
[0001] The invention relates to the field of pipelayers, and in particular to a wetland pipelayer. Background Art
[0002] With the full development of large-scale pipeline construction, the increase in pipe diameter and wall thickness has increased the weight of a single pipe. The deadweight of thick-walled pipes with a diameter of Φ1219 or more is more than 8 tons. The weight of conventional pipelayers with a load capacity of more than 70 tons and excavators with a load capacity of more than 50 tons is generally more than 60 tons. When using the traditional side-lifting method, the average ground contact pressure of the crawler on the load-bearing side is 150KPa, which requires a high ground bearing capacity. However, in wetland areas, due to the high soil moisture content, the low ground bearing capacity cannot meet the requirements of traditional pipelayers for the construction environment. The traditional solution is to lay road slabs, steel plates, pipe rows, etc. in the working zone. Although it has a certain effect, it has problems such as large auxiliary workload and high cost, and is not suitable for large-scale application.
[0003] Therefore, it is necessary to develop a new type of pipe-laying machine so that it can operate normally on low-bearing-capacity surfaces such as wetlands, thus solving the problem of difficult construction in wetlands. Summary of the invention
[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a wetland pipelayer that can still operate normally on low-bearing-capacity ground such as wetlands, is easy to operate and has low cost.
[0005] Technical solution: A wetland pipe laying machine of the present invention is characterized in that it includes a hanging beam structure, a frame structure, a pipe and a chassis; the frame structure is provided with a hanging beam structure on the top, a chassis is provided at the bottom of the frame structure, and a pipe is provided inside the frame structure.
[0006] Wherein, the chassis includes a mounting platform, a third oil cylinder and a crawler chassis.
[0007] Among them, a cylinder three is installed between the crawler chassis, and the mounting platform is welded on the crawler chassis.
[0008] The frame structure includes a first beam, a second beam, a first oil cylinder, a connecting frame and four legs.
[0009] Among them, the four legs are welded on the mounting platform, the two sides of the top of the four legs are connected by a connecting frame, and the other two sides are connected to the beam 2 through the beam 1, and one end of the top of the beam 2 is inserted into the cavity of the beam 1 for sliding and is limited by a pin shaft.
[0010] Wherein, an oil cylinder 1 is arranged on the outer sides of the vehicle beam 1 and the vehicle beam 2.
[0011] Wherein, the hanging beam structure comprises a first hook, a hanging beam, a traction mechanism, a slewing mechanism, a second oil cylinder, a cross beam and a second hook.
[0012] The crossbeam is welded on the vehicle beam one, one end of the slewing mechanism is sleeved on the crossbeam, the other end of the slewing mechanism is fixed to the hanging beam, and traction mechanisms are installed on both sides of the hanging beam. The traction mechanisms pull the hook one and the hook two through the wire rope.
[0013] Wherein, a second oil cylinder is provided on the side of the crossbeam.
[0014] The method for using the wetland pipelayer of the present invention is that the hanging beam structure 1 is at the center of the whole vehicle. When in working state, the two oil cylinders 3 6 are extended to change the track, thereby increasing the distance between the two crawler chassis 7 and reducing the requirement for ground bearing capacity; when changing the track, the two oil cylinders 10 work at the same time, driving the vehicle beam 1 8 and the vehicle beam 2 9 to slide against each other to increase the width of the frame structure 2, and cooperate with the wide track crawler state to work; the traction mechanism 14 drives the hook 12 and the hook 2 18 to realize the lifting and vertical plane rotation of the pipe 3; the oil cylinder 2 16 controls the horizontal movement of the hanging beam 13 to realize the horizontal lateral movement of the pipe 3, and the slewing mechanism 15 realizes the horizontal plane rotation of the pipe 3 by driving the pipe 3 to rotate in the horizontal plane.
[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention provides a new type of wetland pipelayer. When the pipelayer carries the pipe, the steel pipe is placed in the middle of the crawler, and no eccentric load is generated during lifting. The weight eccentricity of the equipment itself is minimized during design to ensure that the ground contact pressure of the crawlers on both sides is basically equal, reducing the requirements for the ground bearing capacity, and can still operate normally on low-bearing-capacity ground such as wetlands. It can realize functions such as pipe lifting, horizontal lateral movement, horizontal plane rotation and vertical plane rotation, with high practicality and economy, solving the construction problems in wetlands and reducing construction costs.

[0024] The method for using the wetland pipelayer of the present invention is that the beam structure 1 is located at the center of the vehicle, which solves the problem of excessive ground contact pressure of the single-side crawler when side-loaded. In the working state, the track is changed by extending the two oil cylinders 3 6, increasing the distance between the two crawler chassis 7 and reducing the requirements for the ground bearing capacity; when changing the track, the two oil cylinders 10 work at the same time, driving the vehicle beam 1 8 and the vehicle beam 2 9 to slide against each other to increase the width of the frame structure 2, and work in the wide track crawler state; the traction mechanism 14 drives the hook 12 and the hook 2 18 to realize the lifting and vertical plane rotation of the pipe 3; the oil cylinder 2 16 controls the horizontal movement of the beam 13 to realize the horizontal lateral movement of the pipe 3, and the slewing mechanism 15 drives the pipe 3 to rotate in the horizontal plane to realize the horizontal plane rotation of the pipe 3.
