Abstract
The invention discloses a supporting device used for supporting an oil cylinder, comprising a supporting seat and a supporting shaft. One end of the supporting shaft is connected with the supporting seat which is used for supporting the oil cylinder. The supporting seat and the supporting shaft are in sliding fit by two self-lubricating devices which are arranged at two ends of the supporting seat respectively. Each self-lubricating device comprises an upper sliding ring, a lower sliding ring and a self-lubricating shaft sleeve which is arranged between the upper sliding ring and the lower sliding ring. The upper sliding ring is connected with the supporting seat and the lower sliding ring is connected with the supporting shaft. A limit stop which is used for preventing the supporting shaft from sliding out of the supporting seat is arranged at the side (close to the supporting seat) of each self-lubricating device. The supporting device provided by the invention not only has good supporting function, but also has the advantages of simpleness in manufacturing and long service life. The supporting device provided by the invention can effectively resolve the problem of hydraulic deflection of small-tonnage radial gates with large-opening surface holes. On the premise that stroke of the oil cylinder is unchanged, the installation size of the oil cylinder is reduced and the safety of the hydrocylinder is improved. In addition, the cost is low and the business prospect is good.
Description
Technical field
The present invention relates to a kind of parts of showing hole arc door hydraulic hoist, be specifically related to a kind of supporting arrangement for support hydraulic headstock gear oil cylinder.
Background technology
The supporting of existing table hole arc door oil cylinder of hydraulic headstock gear is to connect in the end of oil cylinder.And there are following several shortcomings in such supporting form: on the one hand because oil cylinder itself is because deadweight just allows certain amount of deflection, and after using this supporting form, certainly will will increase the installation dimension of oil cylinder, thereby the slenderness ratio of oil cylinder is increased.In use, because installation dimension is long, the amount of deflection of oil cylinder increases oil cylinder, and piston rod easily produces fatigue deformation, causes oil cylinder not use normally.On the other hand, because the amount of deflection of piston rod is excessive, piston rod is oppressed seal for a long time, easily cause the damage of seal, meanwhile, due to the bending of piston rod, between piston rod and seal, easily produce certain space, oil cylinder in use, can produce leakage of oil and piston rod and scrape the situation of damage.The 3rd table hole arc door for little tonnage, long stroke, if use this supporting form, considers the amount of deflection of oil cylinder, will oversize piston bar, the diameter of cylinder body, increase cost of production, and be also a kind of waste of resource simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is: for solve traditional supports occur piston rod amount of deflection excessive, in oil cylinder use procedure, cause leakage of oil and piston rod to scrape damage, and the diameter of oversize piston bar and cylinder body is unfavorable for the problem of cost control, the invention provides a kind of novel supporting arrangement for supporting oil cylinder, change the position of supporting oil cylinder, solve the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: a kind of supporting arrangement for supporting oil cylinder, comprise supporting base and bolster, one end of described bolster is connected with the bearing for supporting oil cylinder, between described supporting base and bolster, be and be slidably matched by two cover self-lubricating devices, two described cover self-lubricating devices lay respectively at supporting base two ends, described self-lubricating device comprises slip ring, downslide rotating ring and being positioned at, self lubrication bearing between downslide rotating ring, described upper slip ring is connected with supporting base, described downslide rotating ring is connected with bolster, described self-lubricating device is provided with and prevents that bolster from skidding off the positive stop of supporting base near a side of bearing.
Further, specifically, described upper slip ring and downslide rotating ring all and between self lubrication bearing are and are slidably matched.
In order to prevent that bolster from skidding off supporting base, two described cover self-lubricating devices are provided with positive stop near a side of bearing.
For sound construction, described positive stop and supporting base are bolted.
Further, as preferably, on described positive stop, be evenly provided with at least 2 screwed holes.
In order to improve the abrasion resistance of slip ring, described upper slip ring and downslide rotating ring are stainless steel material manufacture.
The invention has the beneficial effects as follows, the present invention not only has good support functions, and it is made simple, long service life, has effectively solved the problem of little tonnage, large aperture table hole arc door hydraulic pressure amount of deflection, in the case of ensureing that the stroke of oil cylinder is constant, reduce the installation dimension of oil cylinder, improved the security performance of hydraulic jack, and cost is low, there is good commercial promise.

In figure 1, supporting base, 2, bolster, 3, upper slip ring, 4, downslide rotating ring, 5, self lubrication bearing, 6, positive stop, 7, bearing.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Figure 1-3, the most preferred embodiment of the supporting arrangement for supporting oil cylinder of the present invention, comprise supporting base 1 and bolster 2, one end of described bolster 2 is connected with the bearing 7 for supporting oil cylinder, between described supporting base 1 and bolster 2, be and be slidably matched by two cover self-lubricating devices, two described cover self-lubricating devices lay respectively at supporting base 1 two ends, described self-lubricating device comprises slip ring 3, downslide rotating ring 4 and being positioned at, self lubrication bearing 5 between downslide rotating ring, described upper slip ring 3 is connected with supporting base 1, described downslide rotating ring 4 is connected with bolster 2, described self-lubricating device is provided with and prevents that bolster 2 from skidding off the positive stop 6 of supporting base 1 near a side of bearing 7.Upper slip ring 3 and downslide rotating ring 4 all and between self lubrication bearing 5 are and are slidably matched, two cover self-lubricating devices are provided with positive stop 6 near a side of bearing 7, positive stop 6 is bolted with supporting base 1, on positive stop 6, be evenly provided with at least 2 screwed holes, upper slip ring 3 and downslide rotating ring 4 are stainless steel material manufacture.
Adopt after such structure, because the bearing of this supporting arrangement is the medium position that is bearing in oil cylinder, in the case of ensureing that the stroke of oil cylinder is constant, reduced the installation dimension of oil cylinder, in the process using at oil cylinder, reduced the amount of deflection of oil cylinder.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on manual, must determine its technical scope according to claim scope.
