Abstract
The utility model discloses a sublevel caving coal support pull back chute mechanism which comprises a base and a back conveyor. The base is connected with a back chute supporting plate. The back conveyor is arranged on the back chute supporting plate. Due to the facts that the back chute supporting plate is added at the back of the base, and the back conveyor is placed on the back chute supporting plate, the back conveyor does not contact with a base plate directly. Therefore, the problem that the back conveyor sinks into the base plate when a face is advanced is effectively resolved. Face advance efficiency is improved.
Description
Technical field
The utility model relates to a kind of colliery sublevel caving hydrau lic support, is specifically related to a kind of sublevel caving hydrau lic support with drawing rear slide mechanism.
Background technology
Caving roof coal hydraulic support is the critical equipment of top coal caving method, and the innovation of caving roof coal hydraulic support and development are essential condition and the signs of the innovation of top coal caving method and technology and development.In use, need to use and draw rear slide jack that support and rear portion conveyer are coupled together.And the existing rear slide mechanism of drawing makes the rear portion conveyer be absorbed in base plate when running into loose base plate work plane easily, affects the timely propelling of work plane.
The utility model content
The technical problems to be solved in the utility model is to draw rear slide mechanism inefficiency when loose base plate work plane work, provides a kind of sublevel caving hydrau lic support that can increase work efficiency to draw rear slide mechanism.
The technical solution of the utility model realizes in the following manner: a kind of sublevel caving hydrau lic support draws rear slide mechanism, comprises base, rear portion conveyer, and base links to each other with rear slide supporting plate, and the rear portion conveyer is arranged on the rear slide supporting plate.
Described base is provided with otic placode, and rear slide supporting plate and otic placode are hinged and connected.
The utility model has increased rear slide supporting plate at the base rear portion, the rear portion conveyer is placed on the rear slide supporting plate, so that the rear portion conveyer directly do not contact with base plate, thereby the rear portion conveyer is absorbed in the problem of base plate when efficiently solving the advance of the face, has improved advance of the face efficient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is base and rear slide supporting plate connection status schematic diagram.
The specific embodiment
As shown in drawings, a kind of sublevel caving hydrau lic support draws rear slide mechanism, comprises base 1, rear portion conveyer 3, and base 1 links to each other with rear slide supporting plate 2, and rear portion conveyer 3 is arranged on the rear slide supporting plate 2.
Described base 1 is provided with otic placode 4, and rear slide supporting plate 2 is hinged and connected with otic placode 4.
In the utility model, rear slide supporting plate 2 is formed by Plate Welding, and its front end is hinged by the otic placode 4 on bearing pin and the base 1, and its rear end extends rear portion conveyer 3 bottoms, so that rear portion conveyer 3 does not contact with base plate.
