Abstract
The utility model relates to a novel single hydraulic prop comprising a movable column. The novel single hydraulic prop is characterized in that the part above a limiting spring clamping groove of the movable column has thinner outer diameter, and is sleeved with a stainless steel pipe with the outer diameter equal to that of the movable column; and epoxy resin adhesion layer is filled between the stainless steel pipe and the thinner part of the movable column. The novel single hydraulic prop has a simple structure, the movable column has low production cost, high corrosion resistance, bright and attractive surface, high strength, and resistance to shot firing destroy, so that the single hydraulic prop of the utility model has good sealing performance and long service life, and is energy-saving and environment-friendly.
Description
Technical field: the utility model belongs to mining support technology field, relates to a kind of follow-on hydraulic prop.
Background technology: characteristics such as hydraulic prop is good with its supporting performance at present, and is easy to use have become one of main supporting product of coal in China coal-face.Existing hydraulic prop, its post of living mainly adopts nickel-phosphorus-boron to handle the post surface of living, to satisfy the resistance to corrosion of the post of living.But there is following defective in this hydraulic prop: 1, the processing technology of nickel-phosphorus-boron is just handled the top layer of the post of living, and its resistance to corrosion is general; 2, the processing technology complexity of nickel-phosphorus-boron is unfavorable for environmental protection, and its cost is higher simultaneously; 3, the post alive that nickel-phosphorus-boron processing is handled, its application life is short; 4, adopt in the process at big gun, the post alive that nickel-phosphorus-boron is handled is easy to be damaged, and causes corrosion, not only has a strong impact on the hydraulic prop sealing performance, also is a very serious problem in restriction hydraulic prop life-span.
Summary of the invention: the purpose of this utility model provides a kind of novel hydraulic prop, in order to effectively to overcome the existing above-mentioned drawback of prior art hydraulic prop.The purpose of this utility model is to improve to realize on the basis of prior art hydraulic prop, it comprises post alive, the limit spring draw-in groove that it is characterized in that post alive is thinner with the top external diameter, the outside is set with an external diameter and the identical stainless steel tube of post external diameter of living, and is filled with epoxy resin between stainless steel tube and the thinner part of the post of living and glues together layer.
The utility model is reasonable in design, and is simple in structure, has following advantage: 1, its post outside of living is set with stainless steel tube, have very strong corrosion resistance, and the stainless steel surfaces light is attractive in appearance; 2, the stainless steel tube and the column sleeve dress gummed of living, the intensity of post alive increases, also thoroughly solved simultaneously to adopt and destroyed post overlay coating alive because of big gun, cause corrosion, influence the problem of pillar sealing performance, thereby improved the intensity of hydraulic prop, long service life greatly, hydraulic prop cost of production than existing nickel-phosphorus-boron PROCESS FOR TREATMENT post alive is low simultaneously, energy-conserving and environment-protective.
Description of drawings: Fig. 1 is a structural representation of the present utility model
Fig. 2 is that post master alive of the present utility model looks sectional view
Fig. 3 is the A-A sectional view among Fig. 2
The specific embodiment: accompanying drawing has provided a specific embodiment of the present utility model, below in conjunction with accompanying drawing the utility model is elaborated: according to Fig. 1, Fig. 2, shown in Figure 3,1 is the post of living among the figure, be installed in the oil cylinder 2, spacing spring card slot 3 is arranged at the bottom of post 1 alive, the limit spring draw-in groove 3 of cylinder 1 alive is thinner with the top external diameter, the outside is set with an external diameter and the identical stainless steel tube 4 of post 1 external diameter of living, and is filled with epoxy resin between stainless steel tube 4 and the thinner part of the post 1 of living and glues together layers 5.
