Description
Technical field
The present invention relates to pit gear technical field, particularly relate to a kind of side protection structure of end hydraulic support.
Background technology
In order to better in the safety of underground transportation, exploitation and protection underground work personnel, the side protection structure of end hydraulic support is the prerequisite support apparatus of underground work.In prior art, in the side protection structure design of end hydraulic support side guard board and back timber directly hinged, hydraulic jack is connected with side guard board, and under the driving of hydraulic jack, side guard board rotates around the pin joint with back timber.In said structure, side guard board is mainly protected top, cannot form protection, cause the potential safety hazard to support component and personnel to side, needs to improve.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of side protection structure of end hydraulic support, achieving the improvement to supporting structure, it can form good protection to top and side.
The side protection structure of a kind of end hydraulic support that the present invention proposes, comprise installing plate and n side guard board, side guard board is hinged and connected successively, each side guard board is provided with at least one first syndeton, installing plate has multiple second syndeton, at least one hydraulic jack is provided with between each side guard board and installing plate, the first syndeton is passed through in piston rod one end of above-mentioned hydraulic jack and respective side backplate is hinged and the second syndeton is passed through in cylinder body one end and installing plate is hinged, first syndeton is be fixed on side guard board and have the fan-shaped junction plate of hinge hole, second syndeton has the link slot of hinge hole, wherein, n be more than or equal to 2 natural number, the quantity of the hydraulic jack be hinged with each side guard board is not more than the quantity of the first syndeton on respective side backplate, on installing plate, the quantity of the second syndeton is not less than the summation of the first syndeton quantity on n side guard board.
Preferably, the quantity of side guard board is 2-4.
Preferably, on each side guard board, the quantity of the first syndeton is 2-4, and above-mentioned first syndeton distribution on the same line.
In the present invention, n side guard board head and the tail are hinged, owing to being provided with hydraulic jack between different side guard board and installing plate, thus the rotation forming different angles between different side guard board can be made, therefore, according to protection demand, by adjusting the position of each side guard board flexibly, effect top and side being formed to good protection can be realized; Hydraulic jack is connected with side guard board, installing plate respectively by the first syndeton, the second syndeton, and the first syndeton is designed to the fan-shaped junction plate with hinge hole, second syndeton is designed to the link slot with hinge hole, the junction between hydraulic jack and side guard board, installing plate can be made stressed more reasonable, and the installation of hydraulic jack can be made simpler and easy.
