The utility model is characterized in that the parachute gear is arranged on the top of the cage body; the upper part of a vertical rod is connected with the suspension device; the lower part of the vertical rod is sheathed in a spring sleeve; the spring sleeve is tightly fastened with the cage body; a spring is a pressure spring; the lower end of the vertical rod is provided with a hanging nut, a connecting board, a rotary shaft, and a shifting fork. The utility model has the advantages of simple structure, light weight, simple processing technology, without providing special brake ropes, one rope with two purposes, low cost, which is very popular among county coal mines.
Description
The utility model relates to a kind of mine hoisting device, the cable guide roller sliding wedge type falling protector cage that particularly a kind of vertical shaft hoisting is used.
At present, local mine is Township Coal Mine especially, vertical shaft hoisting container great majority are the single rope cage below a ton, indivedual little collieries even still adopt the container of ancient trailing plants basket as lifting personnel and coal, and the most number average of these canister cages is not with parachute gear.Therefore, its disconnected rope serious accident of falling happens occasionally.In recent years, more and more the importance that promotes safety is recognized in Duo colliery gradually, take safety measures one after another, increase the configuration parachute gear, these safety devices mostly are GS type, BF type or FS type, if they are transplanted on these little cages,, there is following problem though can guarantee safety like this:
(1) these falling protectors are heavy mostly, even the lightest and the handiest BF-111 type falling protector also reaches 330kg, if add two check bands and shock absorber, and anti-drop system only, its weight just will reach thousands of kilograms.
(2) install this falling protector additional, except that need transformation of the way cage, the check band (except the JS type) of two special uses and the anchor fitting of tension check band must newly be installed in pit shaft also.
(3) standard cage and anti-drop system, complex structure many because of member, price are generally expensive.Therefore, a lot of little collieries for economic reasons or factor such as shaft section discomfort, often without the standard cage, but own on the basis of the existing conditions no matter how simple and crude the manufacturing, this is just unavoidable to have stayed hidden danger safely because irrationality of structure gives to promote.
Along with developing rapidly of Township Coal Mine, it is increasing that its coal production accounts for the proportion of national total make, but thing followed safety misadventure is also in rising trend gradually, add up according to pertinent data, in 395 accidents in 91 years national collieries, Township Coal Mine then takes place more than 270, account for 70% of total accident rate, how efficiently and effectively solves the safety problem of Township Coal Mine, more and more cause the great attention of party and state, this also is the eager desire of vast Township Coal Mine, therefore, develop a kind of rational in infrastructure as early as possible, safe and reliable, economical and practical, be fit to the novel cage that Township Coal Mine promotes, then be very important.
The purpose of the utility model is the deficiency at aforementioned prior art, and discloses a kind of be suitable for that small-sized vertical uses have disconnected rope catching device and do not need the small-sized cable guide roller sliding wedge type falling protector cage of special-purpose check band.
The utility model is achieved in that small-sized cable guide roller sliding wedge type falling protector cage, by cage body 4, be contained in the suspension gear 1 on the cage body 4, guide piece 2, interior Obstruct apparatus 5 of jar and the parachute gear 3 that is contained on the cage body 4 are formed, wherein: a, parachute gear 3 is contained in cage body 4 tops, its upright pull bar 7 tops and suspension gear 1 link, the bottom is sleeved in the spring housing 8, spring housing 8 is fastening with cage body 4, spring 9 is a compression spring, and be sleeved on the upright pull bar 7, dress is hung nut 10 in the lower end of upright pull bar 7, hangs nut 10 and links to each other with connecting plate 11, connecting plate 11 links to each other with connecting plate 17 on being fastened on turning cylinder 13, tightens intrinsic shift fork 14 at turning cylinder 13.B, turning cylinder 13 are contained in the bearing 16 of both sides, cage body 4 top, and an end that is fastened on the shift fork 14 on the turning cylinder 13 inserts in the hole of slide block 15.C, guide piece 2 is installed above parachute gear 3.
Good effect of the present utility model is: integral structure is simple, in light weight, cage deadweight (comprising catching device) has only about one ton, its manufacturing processing technic is simple, need not special Fabricating machinery and means, the braking of parachute gear is as arresting supporting member with four cage guide rope, need not to be provided with special-purpose check band, accomplish that a rope is dual-purpose, handicapping car stop in the cage, the shelves of holding up traffic have adopted resistance wheel and the interlock of bucket case to hold up traffic, and are specially adapted to have a power failure suddenly in the lifting process of little ore deposit or other reason causes the situation of bigger swing, catching device adopts roller sliding wedge mode, volume is little, and is in light weight, is active in one's movements, reset easily easy installation and removal.
Description of drawings is as follows:
Fig. 1, front view of the present utility model,
Fig. 2, birds-eye view of the present utility model,
