Abstract
The utility model designs a support roller structure with a hydraulic floating compensation function. The support roller structure comprises a rolled coil. The support roller structure is characterized in that at least three support points are evenly distributed in the circumference on the side surface of the rolled coil by taking the gravity center position of the rolled coil as a circle center; each support point is composed of a plurality of groups of plunger cylinders; each group of plunger pumps are communicated with each other; a roller is connected with a piston rod of each plunger pump, and contacts the rolled coil. The support roller structure has the advantages of compensation function, strong partial load resistance, good shock absorption, good impact resistance and the like.
Description
Technical field
The utility model relates to a kind of support roller structure of hydraulic floating compensate function.
Background technique
Along with global economic integration, marine transportation instrument becomes very important means of transportation.Bottom cable laying equipment has also had further lifting, in existing marine ship equipment, be specifically designed to the support roller structure of submarine pipeline and cable pipe crimping dish and large-sized object, be mainly to adopt traditional hydro-pneumatic spring to realize, its compensation performance is poor, and noise is large, carry the shortcomings such as unbalanced.
Model utility content
The utility model object is that pipe crimping dish has reliable horizontal stability in the situation that of rotation, has played the effect of hydraulic shock-absorption balance in order to guarantee that pipe crimping dish evenly provides a kind of support roller structure of hydraulic floating compensate function at the stressed of all directions.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of support roller structure of hydraulic floating compensate function, comprise, pipe crimping dish, it is characterized in that, the position of centre of gravity of this pipe crimping dish of take in the side of this pipe crimping dish is distributed with at least three strong points as center of circle even circumferential, and by organizing, plunger cylinder forms this strong point and the plunger pump of every group is interconnected more, is connected with a roller and this roller and contacts with this pipe crimping dish on the piston rod of this plunger pump.
The utility model at least has the following advantages:
1, there is compensation performance, because being interconnected, the branched oil cylinder of same support group forms the hydraulic system of a sealing, can automatically adjust according to the inclined degree of pipe crimping dish the extending amount of oil hydraulic cylinder, compensate the roller of discontinuity, the specific contact pressure that guarantees each roller is identical, avoid a certain roller overload, guarantee that each oil cylinder carrying is balanced.
2, have damping balanced action, in order to prevent pipe crimping dish unbalance loading and impact, utilize a plurality of hydraulic ram cylinders to be interconnected, according to the incompressible principle of hydraulic oil, the flow resistance by upper and lower chamber has produced damping effect.Unbalance loading and impact have effectively been avoided.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
The 2500T pipe crimping dish of take is example, and whole equipment comprises that a set of independent pumping plant (load-reacting pump, proportional reversing valve, motor etc.), a centralized control cabinet and 16 plunger cylinders form.According to the position of centre of gravity of pipe crimping dish 1, determine to adopt 4 strong points 2 to carry out load-bearing, each strong point is in series with 4 groups of plunger cylinders.Specifically, after facilitating 1 rotation of cable rolling dish to get up, the balanced horizontal stable with guaranteeing pipe crimping dish of roller carrying, in pedestal circumference, (centered by ∮ 13300mm) minute inside and outside two-layer placement is with the roller of hydraulic jack, by 90 ° 4 uniform putting on pedestal, form four strong points, each strong point 2 is comprised of four oil cylinders, every four oil cylinders are connected together, and four strong points connect respectively hydraulic station.Every group of oil hydraulic circuit be Normally closed type electromagnetism one-way valve all, and energising off-load, prevents hydraulic fluid leak.When pipe crimping dish rotates on uneven wearing plate, plunger cylinder is adjusted extending amount automatically according to the variation of load, guarantees that the carrying of each oil cylinder is balanced.Each support group is all provided with pressure measuring tie-in and pressure transducer, and the pressure that can effectively monitor at any time hydraulic system changes, the work of horizontal stable after assurance pipe crimping disc spins.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (3)
