Abstract
The utility model relates to a telescopic tail of scraper conveyer for coal mine, in particular to a detachable oil cylinder connecting seat for a telescopic tail of a scraper conveyer, which is used under a coal mine well. In the prior art, due to certain self height, the oil cylinder connecting seat welded on a telescopic tail fixing frame of the scraper conveyer can block the falling of a roller of a coal winning machine, triangular coal is left at the tail of the work surface and influences the normal work of the coal wining work. In the utility model, the oil cylinder connecting seat is divided into an upper part and a lower part, and consists of a fastening bolt, a movable seat and a fixed seat; a bolt through hole is arranged at the left end of the movable seat, and a T-shaped convex platform is arranged in the middle of a base; the fixed seat is positioned under the movable seat, the shape of the upper surface of the fixed seat corresponds to that of the lower surface of the movable seat, a bolt counter bore is arranged at the position of the left end, opposite to the bolt through hole in the movable seat, and a T-shaped groove in the middle of the fixed seat is matched with the T-shaped convex platform of the movable seat; and the movable seat is connected with the fixed seat by the fastening bolt. The height of the oil cylinder connecting seat is reduced, so that the purpose of thoroughly cutting the triangular coal is achieved.
Description
Technical field
The utility model relates to a kind of colliery with the flexible tail device of drag conveyor, specifically a kind of coal mine lower scraping plate conveyer detachable oil cylinder connection seat of tail that stretches.
Background technology
Traditional coal mine lower scraping plate conveyer tail that stretches, mainly form by adjustable shelf and fixed mount two large divisions, welding respectively on adjustable shelf and the fixed mount on the oil cylinder connection seat, with oil cylinder one group oil cylinder connection seat is linked up, the flexible adjustable shelf that makes by oil cylinder moves around, thereby reaches the purpose of adjusting chain tension.
The oil cylinder connection seat is a main stressed member, it bears from the institute of oil cylinder strong, therefore require enough height of its intensity, adopt alloy steel to be welded on fixed mount and the adjustable shelf usually, the method technology is simple, the intensity height, but the oil cylinder connection seat self has certain height, and the oil cylinder connection seat that is welded on the fixed mount can hinder the whereabouts of coal mining machine roller, (is commonly called as in the industry thereby can leave over place's triangle coal at the working surface tail place, below all with), influence normally carrying out of coal work.
Summary of the invention
The purpose of this utility model provides the flexible detachable oil cylinder connection seat of tail of a kind of drag conveyor, and the working surface tail place leaves over triangle coal problem under the existing coal mine to overcome, and this oil cylinder connection seat is easy to process, cost is low, good manufacturability, the intensity height can effectively solve the triangle coal problem of leaving over.
The technical scheme that its technical problem that solves the utility model adopts is: the flexible detachable oil cylinder connection seat of tail of drag conveyor is made up of fastening bolt 1, sliding seat 2 and holder 3; Sliding seat 2 left ends are provided with bolt hole, and the bottom interposition is equipped with T shape boss; Holder 3 be positioned at sliding seat 2 below, the bolt hole relative position place of left end and sliding seat 2 is provided with bolt hole, interposition is equipped with T-slot and cooperates with the T shape boss of sliding seat 2; Sliding seat 2 connects by fastening bolt 1 with holder 3.
The beneficial effects of the utility model are: the height problem that has solved the oil cylinder connection seat, by the dismounting sliding seat, reduced the height of oil cylinder connection seat, coal mining machine roller can be fallen, cylinder can be cut rib, thereby has solved the problem that the working surface tail place leaves over the triangle coal.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. fastening bolt, 2. sliding seat, 3. holder.
The specific embodiment
By shown in Figure 1, the flexible detachable oil cylinder connection seat of tail of drag conveyor is made up of fastening bolt 1, sliding seat 2 and holder 3; Sliding seat 2 left ends are provided with bolt hole, and the bottom interposition is equipped with T shape boss; Holder 3 be positioned at sliding seat 2 below, the bolt hole relative position place of left end and sliding seat 2 is provided with bolt hole, interposition is equipped with T-slot and cooperates with the T shape boss of sliding seat 2; Sliding seat 2 connects by fastening bolt 1 with holder 3.
Telescopic oil cylinder is connected to the right-hand member of sliding seat 2, and holder 3 is welded on the base plate and side plate of the flexible tail fixed mount of drag conveyor, by fastening bolt and T-slot sliding seat and holder is linked together.
When drag conveyor is normally mined, remove fastening bolt, sliding seat and telescopic oil cylinder, when coal-winning machine runs to tail, owing to pulled down sliding seat and oil cylinder, the height of oil cylinder connection seat is reduced, coal-winning machine can add the distance of an oil cylinder connection seat to the tail direction oil cylinder that walks on, thereby can cut the triangle coal at tail place; When the tight chain of needs, the T shape boss of sliding seat is installed in the T-slot of holder, telescopic oil cylinder is connected to the right-hand member of sliding seat, tightens fastening bolt simultaneously, thus the flexible purpose that reaches tight chain by pilot operated valve device control oil cylinder.
