Abstract

The utility model discloses a low-self-weight single hydraulic prop and belongs to the technical field of mining machinery. The low-self-weight single hydraulic prop comprises a plunger (1), a middle cylinder (2) and an outer cylinder (3), wherein the plunger is composed of a 4-9mm thick composite material layer I, a 2-3mm thick stainless steel outer wall I and a 4-7mm thick stainless steel inner wall III, the middle cylinder is composed of a 2.5-3.5mm thick stainless steel inner wall I, a 3-13mm thick composite material layer II and a 0.8-1.5mm thick stainless steel outer wall II, and the outer cylinder is composed of a 0.5-4mm thick stainless steel inner wall II, a 5-8mm thick composite material layer III and a 2-7mm thick stainless steel outer wall III. According to the low-self-weight single hydraulic prop, supporting requirements are met, the single body is lightened, and labor intensity of workers for transportation and installation is relieved; effective corrosion resistance is achieved through stainless steel sleeves arranged on the surfaces of the cylinders, and the service life of the single body is prolonged; the adoption of the composite layers enables the electroplating process to be eliminated, and environmental friendliness is achieved.

Description

Hydraulic prop from heavy and light

Technical field

The utility model relates to a kind of hydraulic prop from heavy and light, belongs to the mine equipment technical field.

Background technology

Along with the reserves of the coal on earth's surface are reduced day by day, the excavation depth of mine operation is more and more darker now, therefore ore impacts or the loading of other power and the situation of the abutment pressure of rib is obviously increased, so the consumption of hydraulic prop is also just more and more, a work plane just needs the hundreds of root, even thousands of, some banks are for the needs of mining height coal seam variation and personnel's the safety of passing through, so be equipped with thousands of very up to ten thousand of persons' pillar, but the weight of existing pillar is all very heavy, the quantity of at every turn transporting is all very limited, transporting the time that a whole set of pillar spends often needs just can complete several days working days, seriously delayed operating efficiency.

Summary of the invention

The problem existed for above-mentioned prior art, the utility model provides a kind of hydraulic prop from heavy and light, and the quantity of at every turn transporting of individual prop increases greatly, and operating efficiency obviously improves.

To achieve these goals, the utility model is achieved through the following technical solutions: a kind of hydraulic prop from heavy and light, comprise post alive, middle cylinder and outer shell, described post alive is by the composite layer I of 4～9mm, the stainless steel inwall III of the stainless steel outer wall I of 2～3mm and 4～7mm forms, described middle cylinder is by the stainless steel inwall I of 2.5～3.5mm, the stainless steel outer wall II of the composite layer II of 3～13mm and 0.8～1.5mm forms, described outer shell is by the stainless steel inwall II of 0.5～4mm, the stainless steel outer wall III of the composite layer III of 5～8mm and 2～7mm forms.

Described post alive is comprised of the composite layer I of 5 mm, the stainless steel outer wall I of 3mm and the stainless steel inwall III of 5mm.

Described middle cylinder is comprised of the stainless steel inwall I of 3mm, the composite layer II of 6 mm and the stainless steel outer wall II of 3mm.

Described outer shell is comprised of the stainless steel inwall II of 3mm, the composite layer III of 5mm and the stainless steel outer wall III of 4mm.

The composite material of described composite layer I, composite layer II and composite layer III is comprised of polyurethane, glass fiber and carbon fiber.

The beneficial effects of the utility model are: this structure is compared with common hydraulic prop, middle cylinder, outer shell and the post of living are being combined with of composite bed, stainless steel and composite material, greatly reduce weight itself, make the weight of the mass ratio of hydraulic prop common hydraulic prop of the same type at least reduce by 1/4th; Cylinder surface employing stainless steel sleeve can be effectively anticorrosion, extends the application life of monomer; Use composite layer to reduce and electroplate manufacturing procedure, environmental protection; Alleviate workman's labour intensity, improved the quantity that each pillar transports.

The accompanying drawing explanation

Fig. 2 is the structural representation of post alive in Fig. 1;

Fig. 3 is the structural representation of middle cylinder in Fig. 1;

Fig. 4 is the structural representation of outer shell in Fig. 1.

In figure: 1, the post of living, 2, middle cylinder, 3, outer shell, 4, the outer wall I, 41, the inwall III, 5, the composite layer I, 6, the inwall I, 7, the outer wall II, 8, the composite layer II, 9, the inwall II, 91, the outer wall III, 10, the composite layer III.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figures 1 to 4, this is from the hydraulic prop of heavy and light, comprise post 1 alive, middle cylinder 2 and outer shell 3, described post alive 1 is by the composite layer I 5 of 4～9mm, the stainless steel outer wall I 4 of 2～3mm and the stainless steel inwall III of 4～7mm 41 form, described middle cylinder 2 is by the stainless steel inwall I 6 of 2.5～3.5mm, the stainless steel outer wall II 7 of the composite layer II 8 of 3～13mm and 0.8～1.5mm forms, described outer shell 3 is by the stainless steel inwall II 9 of 0.5～4mm, the stainless steel outer wall III 91 of the composite layer III 10 of 5～8mm and 2～7mm forms, composite layer I 5, the composite material of composite layer II 8 and composite layer III 10 is by polyurethane, glass fiber and carbon fiber form, this composite material can also select the composite material of other intensity height and good toughness to form.

Find that in process of production the thickness when composite layer I 5 is 5mm, the thickness of outer wall I 4 is 3mm, the thickness of inwall III 41 is 5mm, the thickness of inwall I 6 is 3mm, the thickness of outer wall II 7 is 3mm, and the thickness of composite layer II 8 is 6mm, and the thickness of inwall II 9 is 3mm, when the thickness that the thickness of outer wall III 91 is 4mm and composite layer III 10 is 5mm, live post 1, middle cylinder 2 and outer shell 3 can reach best fiting effect.Adopt the hydraulic prop of said structure manufacture and the various performance parameters requirement that the prior art contrast finds to reach hydraulic prop, the proportion of steel is 7.8-7.85 g/cm3, the utility model is by polyurethane, the proportion of the composite material that glass fiber and carbon fiber form is 0.2-2.66 g/cm3, owing to living post 1, replace steel with composite material on middle cylinder 2 and outer shell 3, thereby alleviated the weight of pillar, reduce workman's carrying, the labour intensity of installing, cylinder surface employing stainless steel sleeve can be effectively anticorrosion, extend the application life of hydraulic prop, reduce and electroplate manufacturing procedure, environmental protection.
