Abstract
The utility model relates to a protected suspension single hydraulic prop which comprises a top cover, a movable post, a handle body which is connected with a three-use valve, an oil cylinder and a pedestal. The outer circular surface of the movable post is provided with a composite coating layer. A protection curtain is arranged around the movable post. The upper part of the protection curtain is fixed at the top cover, and the lower part is fixed at the handle body. The thickness of the handle body is reduced, and a three-use valve hole of the handle body is moved up. A guide dustproof ring is arranged between the handle body and the movable post. The protection measurement of the movable post is increased, thereby not only improving the shock resistance and the antiseptic property of the movable post, but also improving the service life of the whole prop; and at the same time, the stroke of the prop is improved, in particular towards a low coal seam, the stroke can be improved by 20 percent, thereby improving the operation performance of the worker. The thickness of the handle body is reduced, thereby not only improving the intensity when a handle pulls the prop, but also reducing the length of the handle and increasing the effective distance between props.
Description
Technical field
The utility model relates to the support apparatus of coal mine machinery, particularly a kind of protection suspension hydraulic prop that is used for girdle under the coal mine.
Background technology
Floated hydraulic prop uses in the colliery at present widely because its superior relatively performance, but because the China Mine Geological complicated condition, environment is abominable, and particularly energy shortage at present also is positive exploitation and utilization to the coal of girdle.Because the outer surface of column alive of floated hydraulic prop is directly exposed in the air, and the outer surface of column of living also is the sealing surface of equipment, therefore very easily be damaged or corrosion, and in case the external surface of the post of living be damaged, whole pillar will lose efficacy, and brought influence for safety in production and supporting effect.For girdle, the stroke of the post of living is subjected to the restriction in space, coal seam, is unfavorable for the exploitation of work plane in addition.
The utility model content
Technical problem: the purpose of this utility model provides a kind of simple in structure, the outer surface of column corrosion that prevents to live, be difficult for impaired, intensity height, the protection suspension hydraulic prop of long service life.
Technical scheme: protection suspension hydraulic prop of the present utility model, it comprises top cover, post alive, the handgrip body that is connected as a single entity with triple-use valve, oil cylinder and base are provided with composite coating on the outer round surface of described post alive, be provided with a circle cutting means enclosure in the periphery of the post of living, cutting means enclosure top is fixed on the top cover, and the bottom is fixed on the handgrip body; Reduce the thickness of described handgrip body, shorten the length of handgrip body, move on the triple-use valve hole with the handgrip body; Be provided with the guiding dust ring between handgrip body and the post alive.
The nickel-phosphorus alloy coating that described composite coating is impact-resistant by one deck, hardness is the iron plating at lower temperature layer more than the HRC50 and improve the outside surface anticorrosion performance constitutes; Described cutting means enclosure is made by folder cloth soft rubber.
Beneficial effect: the utility model is on the basis of existing suspension hydraulic prop, improve at positions such as post, handgrip body to living, the safeguard procedures of post alive have been increased, greatly improved the shock resistance of post alive, not only improved the antiseptic property of post alive, and improved the application life of whole post, improved the stroke of pillar simultaneously, particularly to girdle, its stroke can improve 20%, has improved workman's operating characteristics greatly.The handgrip body adopts the guiding dust ring, has reduced the thickness of handgrip body, moves on the triple-use valve hole with the handgrip body simultaneously, has so not only improved the intensity of handgrip when prop drawing, and has shortened the length of handgrip, the post of increase and the coverage between the post.
Description of drawings
Fig. 1 is a protection suspension hydraulic prop structure chart of the present utility model.
Fig. 2 is the partial enlarged drawing of post alive among Fig. 1.
Among the figure: top cover-1, the post-2 of living, the post cutting means enclosure-3 of living, guiding dust ring-4, handgrip body-5, oil cylinder-6, iron plating at lower temperature layer-2-1, nickel-phosphorus alloy coating-2-2.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Shown in Figure 1, protection suspension hydraulic prop of the present utility model, constitute by top cover 1, the post 2 of living, cutting means enclosure 3, guiding dust ring 4, handgrip body 5, oil cylinder 6 and base 7, oil cylinder 6 is located in the base 7, the post 2 of living is located in the oil cylinder 6, and top cover 1 is located on the post 2 alive, and cutting means enclosure 3 is located at the periphery of post 2 alive, cutting means enclosure 3 tops are fixed on the top cover 1, and the bottom is fixed on the handgrip body 5; Cutting means enclosure 3 is made by folder cloth soft rubber, and when the post of living was subjected to the impact of coal, the impact that can slow down coal greatly prevented that simultaneously coal from splashing on the post alive, to improve the antiseptic property of post alive.The outer round surface of post 2 alive is provided with composite coating, the nickel-phosphorus alloy coating 2-2 that composite coating is impact-resistant by one deck, hardness is the iron plating at lower temperature layer 2-1 more than the HRC50 and improve the outside surface anticorrosion performance constitutes, thickness can reach 0.5mm, use the impact that greatly improves its anti-coal like this at blast mining face.In order to improve the stroke of pillar, be provided with guiding dust ring 4 between handgrip body 5 and the post 2 alive, reduce the thickness of handgrip body 5 like this, move on the triple-use valve hole with the handgrip body simultaneously, not only improved the intensity of handgrip when prop drawing, and the length of handgrip, the post of increase and the coverage between the post have been shortened.
