Abstract
The invention relates to a dual-yoke type heavy steel pile trolley for a cutter suction dredge, which comprises a ship hull, a steel pile, a walking oil cylinder, a track, a trolley main body structure, walking yokes and a cushioning device, wherein the rail is connected with the ship hull, one end of the waling oil cylinder is connected with the trolley main body structure, while the other end is connected with the ship hull, and the upper end of the cushioning device is connected with the trolley main body structure, while the lower end is contacted with the plane of the track. The dual-yoke type heavy steel pile trolley has the advantages of compact and reasonable structure, large bearing capacity and strong rail deformation adaptability. Walking rollers can adjust the position automatically according to the condition of the rail in the walking process to ensure that each walking roller contacts with the rail all the time and bears evenly, thus the service life of the walking rollers is prolonged effectively. By adopting the cushioning device, the walking rollers of a first walking yoke and a second walking yoke contact with the upper surface and the lower surface of the rail respectively; and when the outside wind wave force is large, the cushioning device can prevent the walking rollers from impacting the rail directly so as to play a role in cushioning.

Technical field
The present invention relates to a kind of device of field of ocean engineering, specifically is a kind of cutter suction dredger dual-yoke formula heavy steel pile chassis.
Background technology
Modern large-scale cutter suction dredger adopts the piling bar table system to be shifted usually, table system is by the push-and-pull campaign of walking oil cylinder, by the chassis stroke send index signal accurately control forward pitch from, thereby can big time saver, enhance productivity significantly.
Find through literature search prior art, people such as Jiang Ruhong have delivered " design studies of large-scale cutter suction dredger table system " on the 41st page of " Marine engineering " 2007 the 3rd phase, the system principle and the composition of large-scale cutter suction dredger chassis positioner have been introduced in this article, wherein about the walking subsystem: form by parts such as walking oil cylinder, front walking wheel and wheel carrier, rear walking wheel group and wheel carrier, front and back horizontal guide sheaves.The walking oil cylinder is the drive source that chassis moves forward and backward.Two road wheels of front end can be respectively around the little commentaries on classics of jackshaft, and each two road wheel can be respectively around a little commentaries on classics of axle fore-and-aft direction about the rear end, and six road wheels constitute a self-balancing system, have slightly under the distortion situation at left and right sides track and locking phenomenon can not take place.
Above-mentioned table system generally is applicable to the execution conditions that stormy waves is less, and this moment, track deformation was less, and table system can be finely tuned road wheel core wheel height to adapt to track deformation; But comparing under the severe construction conditions, the suffered external force of table system sharply strengthens, and track deformation also increases thereupon, and above-mentioned table system just can not adapt to, and severe patient can cause damage.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, proposes a kind of cutter suction dredger dual-yoke formula heavy steel pile chassis, two walking york pieces can be rotated, to resist track deformation around the equalizer bar rotating shaft; Two walking york pieces can be rotated, to resist the track longitudinal strain around the rotating shaft of wall frame.
The present invention is achieved by the following technical solutions, the present invention includes: hull, piling bar, walking oil cylinder, track, chassis agent structure, walking york piece, buffer, track links to each other with hull, walking oil cylinder one end is connected with the chassis agent structure, the walking oil cylinder other end is connected with hull, the buffer upper end is connected with the chassis agent structure, and the buffer lower end contacts with orbit plane, and the walking york piece is connected with the chassis agent structure.
The walking york piece comprises some walking rollers, roller wheel shaft, the rotating shaft of wall frame, equalizer bar, roller wall frame, equalizer bar rotating shaft, wall frame rotating shaft, coplane vertical with the equalizer bar rotating shaft, the rotating shaft of wall frame is perpendicular to track, and the equalizer bar shaft parallel is in track, roller wheel shaft and wall frame shaft parallel
The equalizer bar roller end is connected with the chassis agent structure, is rotatably connected between chassis agent structure and the equalizer bar rotating shaft; The roller wheel shaft end is connected with roller wall frame, is rotatably connected between roller wheel shaft and the roller wall frame,
Walking roller is connected by the roller wheel shaft hinge with roller wall frame, is rotatably connected between walking roller and the roller wheel shaft; Roller wall frame is connected by wall frame rotating shaft hinge with equalizer bar, is rotatably connected between rotating shaft of wall frame and the equalizer bar.
Described walking york piece comprises the first walking york piece, the second walking york piece, the first walking york piece is identical with the second walking york piece, the first walking york piece and the second walking york piece are located at the both sides of chassis agent structure symmetrically, and the first walking york piece is connected with chassis agent structure hinge by the equalizer bar rotating shaft respectively with the second walking york piece.
The core wheel of the walking roller of the core wheel of the walking roller of the described first walking york piece and the second walking york piece is not at grade.
Described walking oil cylinder one end is connected by flange with the chassis agent structure, and the walking oil cylinder is a two-way cylinder.
Described buffer upper end is connected by welding manner with the chassis agent structure.
Described track comprises two, all is welded on the hull.
Operating principle of the present invention is: when walking oil cylinder promotion chassis is walked in orbit, chassis agent structure and two walking york pieces are by equalizer bar rotating shaft hinge, therefore two walking york pieces can rotate around the chassis agent structure, promptly can following left both sides orbit altitude difference change the height and position of regulating the both sides walking roller voluntarily, to adapt to the track deformation requirement; Simultaneously, roller wall frame and equalizer bar are by wall frame rotating shaft hinge, thereby roller wall frame can rotate around the rotating shaft of wall frame, reaches the purpose that adapts to the track longitudinal strain.
Owing to adopted such scheme, the present invention to have following characteristics: cutter suction dredger dual-yoke formula heavy steel pile chassis compact conformation of the present invention is reasonable, and bearing capacity is big, has very strong track deformation adaptive capacity.Walking roller can guarantee that each walking roller contacts with track all the time according to the situation of track adjusting position voluntarily in the process of walking, and evenly carrying has prolonged shelf life of walking roller effectively, simultaneously external force is passed to Ship Structure equably.Adopted buffer, having made the walking roller of win the walking york piece and the second walking york piece contact the soffit and the upper surface of track respectively, buffer can avoid walking roller directly to clash into track when extraneous stormy waves power is big, thereby plays cushioning effect.The present invention is suitable for large-scale cutter suction dredger, even it relatively also can constructed under the severe construction conditions.
