Abstract
The invention relates to a hydraulic submarine cable cable-passing bridge frame which is composed of a bridge frame body, an amplitude-changing oil cylinder, a rotation oil cylinder, a cable-passing bridge frame hinged seat and a self-rotating type pedestal. The bridge frame body is connected with the self-rotating type pedestal via the cable-passing bridge frame hinged seat, and the bridge frame body and the cable-passing bridge frame hinged seat are connected in a rotating way along a vertical direction of a bridge frame axis. The amplitude-changing oil cylinder is connected between the bridge frame body and the self-rotating type pedestal. The rotation oil cylinder is connected between the self-rotating type pedestal 5 and a pedestal. With combination of a self-rotating type cable-bearing disc, stress of a submarine cable can be released via movement of the cable-passing bridge frame during the laying process of the submarine cable, and damage generated by suddenly increased stress on the submarine cable during the construction process is ensured to be avoided.
Description
Technical field
The hydraulic pressure sea cable that the present invention relates to discharge in a kind of extra large cable laid processes cable moment stress is crossed cable crane span structure.
Background technology
At present, state inland sea cable lays mostly and adopts and hold cable circle, fixed back twist frame cabling technique; More advanced employing self-rotary holds cable dish, the fixed cable frame cabling technique of crossing.Above-mentioned each technique all exists in extra large cable laid processes cannot discharge the extra large cable stress problem that boats and ships displacement instantaneous variation is brought.
Summary of the invention
In order to overcome the problems referred to above that exist in existing extra large cable laid processes, the invention provides a kind of hydraulic pressure sea cable and cross cable crane span structure, in conjunction with self-rotary, hold cable dish, can in extra large cable laid processes, pass through the motion of cable crane span structure and discharge extra large cable stress, can guarantee in work progress that extra large cable was not because the stress of uprushing produces damage.
The scheme that the present invention solves its technical problem employing is: a kind of hydraulic pressure sea cable is crossed cable crane span structure, by crane span structure main body, amplitude oil cylinder, rotary oil cylinder, mistake cable crane span structure twisted seat and self-rotary base, formed, be characterized in: crane span structure main body was passed through cable crane span structure twisted seat and connected self-rotary base, and crane span structure main body is rotatably connected along crane span structure axis vertical direction with crossing between cable crane span structure twisted seat, between crane span structure main body and self-rotary base, be connected with amplitude oil cylinder, between self-rotary base 5 and base, rotary oil cylinder be housed.
The plane self-aligning bearing horizontally rotating for crossing cable crane span structure is housed below self-rotary base.
The invention has the beneficial effects as follows;
Fixed extra large cable crane span structure is designed to can be along crane span structure axis vertical direction, horizontal direction rotation.When in cabling construction, route fore-and-aft direction, left and right directions skew occur suddenly boats and ships, hydraulic pressure sea cable is crossed cable crane span structure and is automatically followed running by oil pump control, thereby control extra large cable stroke, discharges its stress.
The present invention holds cable dish in conjunction with self-rotary, can in extra large cable laid processes, pass through the motion of cable crane span structure and discharge extra large cable stress, can guarantee in work progress that extra large cable is not because the stress of uprushing produces damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, hydraulic pressure of the present invention sea cable is crossed cable crane span structure, comprises crane span structure main body 1, amplitude oil cylinder 2, rotary oil cylinder 3, crosses cable crane span structure twisted seat 4, self-rotary base 5, base 6.
Crane span structure main body 1 was passed through cable crane span structure twisted seat 4 and was connected self-rotary base 5, and crane span structure main body 1 is rotatably connected along crane span structure axis vertical direction with crossing between cable crane span structure twisted seat 4, between crane span structure main body 1 and self-rotary base 5, be connected with amplitude oil cylinder 2, between self-rotary base 5 and base 6, rotary oil cylinder 3 be housed.
Crane span structure main body 1 adopts steel structure truss processing and fabricating, lightweight construction, and its line style meets the requirement of extra large cable minimum bending radius.
Angling cylinder 3 adopts hydraulic jack, is responsible for making chassis revolution, the requirement changing to adapt to extra large cable Internal and external cycle
Cross cable crane span structure twisted seat 4 and adopt steel construction pin shaft structures, made the cable crane span structure can pitching luffing.
Self-rotary base 5, adopts plane self-aligning bearing, and cable crane span structure can be horizontally rotated.
