Abstract
The utility model discloses a lifting device used during dismantling a fully mechanized mining bracket, which comprises four anchor rod hooks used for being anchored on a top plate, each anchor rod hook is used for hooking a hydraulic cylinder the bottom end of which is fastened with a lifting rope. The utility model realizes the lifting operation during dismantling the fully mechanized mining bracket by utilizing a hydraulic principle, has simple structure, convenient operation and labor saving and is particularly suitable for the lifting operations in a narrow coal mining face.
Description
Technical field
The utility model relates to the device of using when removing equipment under the coal mine.
Background technology
At present, mining face under mine has been adopted in the colliery, and when needing to remove fully mechanized mining supporter replacing work place, because the fully mechanized mining supporter volume is big, heavy, the underground work space is narrow and small, is not easy lifting.Traditional way is to remove artificial slope on the base plate in place, be dragged on the flat truck with drawing hoist, or with the chain block lifting of building a framework, very inconvenient.
Summary of the invention
The purpose of this utility model is that a kind of fully mechanized mining supporter of design is removed lifting appliance, solves the problem of removing and lifting by crane fully mechanized mining supporter inconvenience in the small space of down-hole.
A kind of fully mechanized mining supporter is removed lifting appliance, and it comprises four anchor pole hooks that are used to be anchored on the top board, and each anchor pole hook colludes and tangles a hydraulic actuating cylinder, and the bottom of hydraulic actuating cylinder has fastened the lifting rope.
During use, respectively beat bolthole on the top board at four angles of fully mechanized mining supporter above residing, make a call to four holes altogether, the anchor pole hook is fixed in the bolthole, collude tangle hydraulic actuating cylinder after, with the lifting rope four angles of fully mechanized mining supporter are toggled, inject the backhaul pressure oils for simultaneously four hydraulic actuating cylinders, the hydraulic actuating cylinder withdrawal can easily be sling the fully mechanized mining supporter of heaviness.After slinging flat truck is pushed below the support, annotate process oil for four hydraulic actuating cylinders again, hydraulic actuating cylinder stretches out, and loosens the lifting rope, takes off rope then, finishes crane lifting service.
The utility model simple structure, easy to operate, laborsaving, be particularly useful for lifting operation in narrow and small coal-face.
Description of drawings
Fig. 1 is structure and the running condition scheme drawing of the utility model embodiment.
Marginal data: 1-anchor pole hook; The 2-hydraulic actuating cylinder; 3-lifts by crane rope; The 4-top board; The 5-fully mechanized mining supporter; 6-rail wheel type flat truck.
The specific embodiment
Below in conjunction with use enforcement of the present utility model is described.
As shown in the figure, the utility model comprises four anchor pole hooks 1 that are used to be anchored on the top board 4, and each anchor pole hook 1 colludes and tangles a hydraulic actuating cylinder 2, and the bottom of hydraulic actuating cylinder 2 has fastened lifting rope 3.
During use, respectively beat bolthole on the top board 4 at 5 four angles of fully mechanized mining supporter above residing, make a call to four holes altogether, anchor pole hook 1 is fixed in the bolthole, collude tangle hydraulic actuating cylinder 2 after, with lifting rope 35 four angles of fully mechanized mining supporter are toggled, give four hydraulic actuating cylinders 2 injection backhaul pressure oils simultaneously, hydraulic actuating cylinder 2 withdrawals can easily be sling the fully mechanized mining supporter 5 of heaviness.After slinging rail wheel type flat truck 6 is pushed below the fully mechanized mining supporter 5, give four hydraulic actuating cylinder 2 notes process oil again, hydraulic actuating cylinder 2 stretches out, and loosens and takes off lifting rope 3, finishes crane lifting service.
