Description

Technical Field

[0001] The invention relates to the field of pipelayers, and in particular to a swing-type 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 swing-type wetland pipelayer, which can still operate normally on low-bearing-capacity ground such as wetlands, is easy to operate and has low cost.

[0005] Technical solution: A swing-type wetland pipe laying machine of the present invention is characterized in that it includes a frame structure, a hanging beam structure is provided on the top of the frame structure, a chassis is provided at the bottom of the frame structure, and a pipe is provided inside the frame structure; the frame structure includes two parallel vehicle beams, two parallel cross beams are provided between the vehicle beams, two swing arms are provided at four connection points between the vehicle beams and the cross beams, and the two swing arms are connected by a plurality of pin shafts.

[0006] Wherein, the chassis includes a mounting platform, a crawler chassis and a cylinder.

[0007] Wherein, an oil cylinder is installed between the crawler chassis, and the mounting platform is welded on the crawler chassis.

[0008] Wherein, the frame structure is provided with 4 swing arm legs, each swing arm leg includes 2 swing arms, the swing arms are connected to the mounting platform through a pin shaft, and the swing arms are connected to the vehicle beam through a pin shaft.

[0009] 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.

[0010] Wherein, the crossbeam is welded on the vehicle beam.

[0011] Among them, one end of the slewing mechanism is sleeved on the crossbeam, and the other end of the slewing mechanism is fixed to the suspension beam.

[0012] Wherein, traction mechanisms are installed on both sides of the hanging beam, and the traction mechanisms pull the first hook and the second hook through steel wire ropes.

[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 is located at the center of the whole vehicle, and in the working state, the first oil cylinder at two locations is extended to change the track, thereby increasing the distance between the two crawler chassis and reducing the requirement for ground bearing capacity; when changing the track, the distance between the crawler chassis becomes larger, and the installation platform drives the swing arm to rotate sideways around the vehicle beam, thereby lowering the overall height of the frame structure and cooperating with the wide track crawler state; the traction mechanism drives the first hook and the second hook to realize the lifting and vertical plane rotation of the pipe; the second oil cylinder controls the horizontal movement of the hanging beam to realize the horizontal lateral movement of the pipe, and the slewing mechanism drives the pipe to rotate in the horizontal plane to realize the horizontal plane rotation of the pipe.

[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 hanging beam structure 1 is at the center of the whole vehicle. When in working state, the suspension beam structure 1 is extended by two oil cylinders 7 to change the track, thereby increasing the distance between the two crawler chassis 6 and reducing the requirement for ground bearing capacity; when changing the track, the distance between the crawler chassis 6 becomes larger, and the mounting platform 5 drives the swing arm 9 to rotate sideways around the vehicle beam 11, thereby lowering the overall height of the frame structure 2 to cooperate with 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 hanging 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.
