Abstract
The utility model relates to a vice vertical-shaft hoisting-cage safety door, in particular to a hydraulic curtain type safety door, belonging to the technical field of coal mine machinery. The safety door comprises a door body, and a hydraulic cylinder is arranged in one side of the door body. A pulley block is arranged at the upper part of the door body and comprises a fixed pulley I, a fixed pulley II and a movable block connected with the hydraulic cylinder. The retraction and extension of a piston rod of the hydraulic cylinder is utilized to drive a door curtain of the safety door to move upwards and downwards, so that the safety door is opened and closed. The safety door has the characteristics of simple and reasonable structure, fast opening and closing, high reliability and convenience for installing and maintaining and is suitable for vice vertical-shaft hoisting systems with larger-width cages. The installing space can be effectively reduced, and the construction difficulty of shaft bottom caverns is reduced.
Description
Technical field
The utility model relates to a kind of secondary vertical shaft hoisting cage safety door, is specifically related to a kind of curtain door that surges, and belongs to the coal mine machinery technical field.
Background technology
" safety regulations in coal mine " regulation; For guaranteeing shaft hoisting safety; The personnel of preventing get into the hazardous location personnel's falling accident take place, and perhaps owing to the malfunctioning generation mine car of stop device falling accident, the vertical shaft well head reaches the turnover car side that respectively promotes the stage casing all need install safety door; Can when cage arrives well head or promote the stage casing, open, cage leaves well head or close when promoting the stage casing, plays the reliable protection effect.Safety door is opened to be needed flexibly, and helps the various operations in well head and stage casing.At present, mine secondary vertical shaft hoisting cage safety door, principal mode has two kinds of Driven by Hydraulic Cylinder brace roller type, hydraulic driving translational formulas.Wherein: Driven by Hydraulic Cylinder brace roller type safety door; Its body is connected on the slideway through roller; Slideway can be channel-section steel or I-beam section; One end of slideway is hinged on the door frame, and an other end links to each other with the piston rod top of oil cylinder, and the gradient that produces when utilizing oil cylinder flexible freely glides cage and realizes opening or closing action.The weak point that exists is: speed is inhomogeneous, startup is slow, bump is serious when putting in place; It is inaccurate to put in place, has distortion just can not put in place or rebound seriously slightly; Under when lengthening material, need the dismounting safety door.
Another kind of hydraulic driving translational formula safety door mainly is made up of hydraulic efficiency pressure system, left and right door, support and slideway, HM Hydraulic Motor, sprocket wheel, chain etc.This door is to lean on HM Hydraulic Motor pulling sprocket wheel, chain to drive door leaf and slide, and each is driven the both sides door leaf by a motor.The weak point that exists is: when the cage width was big, the installing space that needs was bigger, has increased shaft bottom Chamber Construction difficulty.
Summary of the invention
The purpose of the utility model is for overcoming the weak point of above-mentioned prior art; A kind of curtain door that surges is provided, and this safety door includes a body, in the Men Tiyi side hydraulic actuating cylinder is arranged; Assembly pulley is arranged at described door body top; The movable pulley that assembly pulley includes fixed pulley I, fixed pulley II and is connected with hydraulic actuating cylinder utilizes the withdrawal of hydraulic cylinder piston rod and stretches out to drive the safety door door curtain and make progress and move downward, and safety door is opened and closed.That this safety door has is simple and reasonable, open and close fast, reliability characteristics high, convenient for installation and maintenance, is applicable to the secondary mine shaft hoist system that the cage width is bigger; Can effectively reduce installing space, reduce shaft bottom Chamber Construction difficulty.
The utility model is realized with following technical scheme: a kind of curtain door that surges; Safety door includes a body; In the Men Tiyi side hydraulic actuating cylinder is arranged, it is characterized in that: there is assembly pulley on described door body top, the movable pulley that assembly pulley includes fixed pulley I, fixed pulley II and is connected with hydraulic actuating cylinder; Also have door curtain on the described door body, door curtain includes and places a railing of body bottom and be fixed in a chain on body top; Described shackle line comprises two groups of shackle line I and shackle line II; One end of shackle line I is fixed on a side of railing through wire rope grip; The other end of shackle line I is connected with fixed pulley I, fixed pulley II, movable pulley; One end of shackle line II is fixed on the opposite side of railing through wire rope grip, and the other end of shackle line II is connected with fixed pulley II, movable pulley.
Railing in the said door curtain can upwards fold.
The switching of said safety door is a perpendicular movement up and down.
A grooving is arranged on the said fixed pulley I, two groovings are arranged on fixed pulley II and the movable pulley.
The utility model has the advantages that: curtain every curtain operating ratio of surging is steady, starting is fast, puts in place accurately, impacts less when putting in place; Have related parameter can also regulate the time that door curtain moves through adjusting, make the impact of door curtain meet concrete requirement, this safety door has the failure-free protective action, can keep out mine car safely and impact, and door is opened flexibly, is convenient to various operations; Operation provides power by hydraulic power unit, can guarantee " safety interlocking ", can when hydraulic actuating cylinder meets accident, with manpower door be opened again.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain:
Accompanying drawing 1 is the utility model structural representation:
Among the figure: 1, door body, 2, hydraulic actuating cylinder, 3, movable pulley, 4, the fixed pulley I, 5, the fixed pulley II, 6, the shackle line I, 7, the shackle line II, 8, railing, 9, chain.
The specific embodiment
As shown in the figure: a kind of curtain door that surges, safety door includes a body 1, and hydraulic actuating cylinder 2 is arranged in the Men Tiyi side, and there is assembly pulley on described door body top, the movable pulley 3 that assembly pulley includes fixed pulley I 4, fixed pulley II 5 and is connected with hydraulic actuating cylinder; Also have door curtain on the described door body, door curtain includes and places a railing of body bottom 8 and be fixed in a chain on body top 9; Described shackle line comprises shackle line I 6 and 7 liang of groups of shackle line II; One end of shackle line I is fixed on a side of railing 8 through wire rope grip; The other end of shackle line I is connected with fixed pulley I, fixed pulley II, movable pulley; One end of shackle line II is fixed on the opposite side of railing 8 through wire rope grip, and the other end of shackle line II is connected with fixed pulley II, movable pulley.
Railing 8 in the said door curtain can upwards fold.
The switching of said safety door is a perpendicular movement up and down.
