Abstract
The utility model relates to a static pressure unload lifting sliding hydraulic cylinder which is in particular used for lifting and supporting large-scale heavy-load objects to make parallel moving, belonging to the technical field of the hydraulic pressure construction equipment. The inside of the cylinder body of the hydraulic cylinder is equipped with a plunger piston. A sealing ring is equipped between the cylinder body and the plunger piston. The utility model is characterized in that the inside of the plunger piston is equipped with an oil guide hole. A rounded end base is connected with the spherical surface of the plunger piston. The inside of the rounded end base is equipped with an oil guide hole and an oil guide groove. The oil guide hole is communicated with the oil guide hole. The rounded end base is pressed on a guideway by the plunger piston. The utility model has simple, compact and rational structure, the oil pressure lifts the burthen and by the slide of the rounded end base of the hydraulic cylinder on the guideway, the lifting oil pressure is introduced into the sliding support surface of the rounded end base simultaneously, so the frictional force can be reduced during the slide. The frictional force is small, which can reduce the driving power during the parallel move. The sliding structure is more durable, safe and reliable.
Description
Technical field
The utility model relates to a kind of Static Unloading Lifting-up Slippage Cylinder, specifically is used for jacking support large-scale heavy duty object and does the translation resettlement, belongs to the hydraulic construction equipment technical field.
Background technique
Using the oil hydraulic cylinder jacking to support weight and carry out translation, is the method for often using in the large-scale heavy duty object displacement construction work, and the frictional force when reducing slippage must be installed the less resistance to compression of friction factor, high-abrasive material on slip plane.In the heavy duty slippage engineering, selecting antifriction material is the key issue of construction.Before the utility model is made, in prior art, being used for jacking supports the large-scale heavy duty object to make the jacking slippage oil cylinder of translation resettlement mainly is in conventional oil cylinder bottom portion a plunger to be housed, outer oil sources supplies pressure oil from filler opening to cylinder body, promote plunger jack-up heavy burden, with seal ring sealing, guarantee that high pressure oil does not have leakage between cylinder body and the plunger, between plunger base and guide rail, place friction factor such as polyfluortetraethylene plate little make gliding material.The polyfluortetraethylene plate of this kind structure is made gliding material, and friction factor is little, and is with high costs, and difficulty is installed, and compressive strength is lower.As select for use common metallic material to make the antifriction medium, and though intensity is high, friction factor is big, translational thrust is very big.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of static pressure unloading way, adopt oil pressure jack-up heavy burden, rely on end seat slippage on guide rail of oil cylinder, frictional force in the time of reducing slippage, frictional force is littler, more durable, the more reliable Static Unloading Lifting-up Slippage Cylinder of Sliding Structures.
Main solution of the present utility model is achieved in that
The utility model mainly adopts plunger 3 is housed in the cylinder block 1, between cylinder body 1 and the plunger 3 seal ring 4 is housed, feature is to be shaped in plunger 3 inside to draw oilhole 10, sphere end seat 6 is connected with plunger 3 spheres, be shaped on oil guiding hole 11 and oil guide slot 8 in the inside of sphere end seat 6, oil guiding hole 11 with draw oilhole 10 and be communicated with, sphere end seat 6 is pressed on the guide rail 9 by plunger 3.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to adopt oil pressure jack-up heavy burden, rely on sphere end seat slippage on guide rail of oil cylinder, the jacking oil pressure of oil cylinder is introduced on the slippage supporting surface of sphere end seat simultaneously, the frictional force in the time of reducing slippage, frictional force is littler, the driving power in the time of reducing translation; Sliding Structures is more durable, safer, reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly by cylinder block 1, filler opening 2, plunger 3, seal ring 4,5,7, sphere end seat 6, oil guide slot 8, guide rail 9, draw oilhole 10, oil guiding hole 11 etc. and form.
A plunger 3 is housed in one-way cylinder cylinder body 1, and outer oil sources supplies pressure oil from filler opening 2 to cylinder body 1, promotes plunger 3 jack-up heavy burdens, between cylinder body 1 and the plunger 3 seal ring 4 is housed, and seals, and guarantees that high pressure oil does not have leakage.Be shaped in plunger 3 inside and draw oilhole 10, draw oilhole 10 oil pressure is caused sphere end seat 6, sphere end seat 6 adopts spheres to be connected with plunger 3.Seal ring 5 is housed between sphere end seat 6 and the plunger 3 is used for reliable sealing, guarantee that high pressure oil does not have external leakage.Be shaped on oil guiding hole 11 and oil guide slot 8 in the inside of sphere end seat 6, in-oil cylinder oil pressure is caused annular oil duct, annular oil duct is arranged on sphere end seat 6, on sphere end seat 6 seal ring 7 is housed simultaneously, prevents that fluid from leaking.Because the bearing area in the seal ring 7 is more smaller than the bearing area of plunger 3, so sphere end seat 6 is pressed on the guide rail 9 by plunger 3.Because the bearing area in the seal ring 7 is the 90%-98% of the bearing area of plunger 3, therefore cause the positive pressure of frictional force, have only the 2%-10% of top lift.
The utility model relies on base to be installed on the heavy burden, by oil pressure jack-up heavy burden, rely on sphere end seat slippage on guide rail of oil cylinder, the jacking oil pressure of oil cylinder is introduced on the slippage supporting surface of sphere end seat simultaneously, make the positive pressure of slippage supporting surface, balanced 90%-98% by oil pressure, even so cylinder iron as gliding material, the friction factor of equivalence also can be low to moderate 0.01-0.005.Use such static pressure off-load jacking cylinder to do heavily loaded slippage, sliding friction power is just very little.
