Embodiment Construction

[0019] This shielding frame is a light-duty shielding frame for removing the working face, including a sliding beam 1, a top beam 2, an elongated base 3, and an elongated push seat 4. The hydraulic prop 10 is fixed through the socket on the elongated base 3. The column head is hingedly matched with the top beam 2 through the column cap. A cover beam 8 is hinged at the rear of the top beam 2, and a connecting rod 9 is arranged between the cover beam 8 and the base, forming a four-bar linkage mechanism. The left and right sides of the top beam 2 and the shield beam 8 are provided with a front side guard plate 7 and a rear side guard plate 6 .

[0020] The sliding beam 1 is slidably connected with the top beam 2 through the chute, which can increase the front support area of ​​the shield frame, and the telescopic length of the sliding beam 1 reaches 1.6m. The head end of the sliding beam 1 is connected to the middle part of the top beam 2 through a jack for providing sliding for...

Abstract

The invention aims at providing a light shielding frame for removing a working face. The light shielding frame for removing the working face is applicable to driving working face removing operation of a fully mechanized coal mining face, can improve the stability of driving working face supporting and can also ensure usage reliability and flexibility. According to the technical scheme for achieving the purpose, the light shielding frame for removing the working face comprises a top beam, a shield beam and a base, wherein the top beam is hinged to the shield beam, a sliding groove formed in the top beam is movably connected with a slippage beam, the top beam is connected with the lengthened base through hydraulic props, the shield beam is connected with the lengthened base through connecting rods, and a lengthened displacement base is connected onto the lengthened base through a jack. The light shielding frame for removing the working face has the advantages that the frame is controlled by adopting adjacent frames; a formed frame-free region can be quickly and effectively supported, the retracting stroke of the slippage beam of the frame is up to 1.6 m, the frame-free region can be timely and temporarily supported, and an empty-support operation phenomenon is fundamentally and completely eradicated; three shielding frames can achieve quick alternative step-by-step displacement without pulling by means of a prop drawing winch; the shielding frame close to one side of a goaf is provided with a lateral protective device.

Description

technical field [0001] The invention relates to a mine support mechanical equipment, in particular to a head-on protection bracket of a four-bar linkage mechanism in a fully mechanized mining removal working face. Background technique [0002] With the continuous update and development of science and technology, comprehensive mechanized coal mining technology has gradually become the mainstream of coal mining technology development, and it has been widely used in more and more mines. The removal of the fully mechanized mining face is not only an important link to ensure the normal replacement of the mining face in the mine, but also a strong guarantee for high and stable production. It is also a safety management due to the high pressure on the roof, the tight removal schedule, many processes, large equipment volume, and heavy tonnage. weakness. At present, single hydraulic props are generally used in the retreat of the fully mechanized mining face to maintain the head empt...
