Abstract
The utility model discloses a top beam of an end support assembly comprising double supports. The top beam comprises a top beam body. A left face guard and a right face guard are respectively hinged on two sides of the top beam body, a left support jack and a right support jack which control the left face guard and the right face guard when the left face guard and the right face guard downwardly swing are respectively hinged between the left face guard and the top beam body and between the right face guard and the top beam body, and the downwards swinging angle range of each of the left face guard and the right face guard is 0-90 degrees. The top beam has the advantages that the left face guard and the right face guard which are driven by the left support jack and the right support jack are respectively arranged on the two sides of the top beam body, so that the left face guard and the right face guard can be positioned at optional angles between the horizontal line and a downwards swinging 90-degree angle, and the adaptability of the end support assembly to the width variation of a roadway is greatly improved.
Description
Technical field
The utility model relates to mining two one group of face end supports, especially relates to a kind of two one group of face end support back timbers.
Background technology
Two one group of face end supports are modal a kind of roadway support patterns, because the influence that pressed by unpredictable ore deposit, roadway deformation is the problem that often runs into, this just makes and has produced a pair of contradiction between back maintenance and the roadway support support width, if the set cap width is too small, can not finely safeguard top board, can not provide enough trouble free service spaces for work plane; If the set cap width is enough, when running into roadway deformation, it is stuck in the tunnel, traversing carriage will be met difficulty, and at this moment just must expand group to the tunnel and could pass through, the waste lot of manpower and material resources.
Summary of the invention
It is a kind of simple in structure, easy to use that the utility model purpose is to provide, and can satisfy two one group of face end support back timbers that span length changes demand and uses manpower and material resources sparingly.
For achieving the above object, the utility model can be taked following technical proposals:
Described in the utility model two one group of face end support back timbers, comprise the back timber body, the both sides of described back timber body are hinged with the left and right side side board respectively, be hinged with the left and right support jack of the described left and right side side board bottom of control between described left and right side side board and back timber body respectively, the bottom angular range of described left and right side side board is 0-90 °.
The utility model advantage is to be respectively equipped with the left and right side side board that left and right support jack drives by the both sides at the back timber body, make the left and right side side board can be in arbitrarily angled between level and the bottom 90 degree, improved the compliance that face end support changes span length widely.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model extended configuration structural representation.
Fig. 3 is the utility model contraction state structural representation.
The specific embodiment
As shown in Figure 1, 2, 3, described in the utility model two one group of face end support back timbers, comprise back timber body 1, the both sides of described back timber body 1 are hinged with left side side board 2 and right side side board 3 respectively, described left and right side side board 2,3 bottom are respectively equipped with left side board ear seat 6, right side board ear seat 7, and the both sides of described back timber body 1 are respectively equipped with left top beam ear seat 8 and right top beam ear seat 9; Left side side board ear seat 6, left top beam ear seat 8 are hinged with piston rod, the cylinder body that jack 4 is supported on a left side respectively; Right side board ear seat 7, right top beam ear seat 9 are hinged with piston rod, the cylinder body that jack 5 is supported on the right side respectively.In use when a left side, the right jack 4 that supports, when 5 piston rod stretches out fully, promote a left side, right side side board 2,3 last plane can keep level with plane on the back timber body 1, can safeguard top board well, support the working environment of a safety for personnel operation, the environment of a safety also can be provided for equipment simultaneously, work as a left side, the right jack 4 that supports, when 5 piston rod is regained fully, a pulling left side, right side side board 2,3 bottoms, 90 degree, thereby support can be reduced greatly on width, and because on a left side, the right jack 4 that supports, 5 driving bottom left, right side side board 2,3 can be in arbitrarily angled between level and the bottom 90 degree, have improved the compliance that face end support changes span length widely.
Claims (1)
1. two one group of face end support back timbers, comprise back timber body (1), it is characterized in that: the both sides of described back timber body (1) are hinged with left and right side side board (2,3) respectively, be hinged with the left and right support jack (4,5) of control described left and right side side board (2, the 3) bottom between described left and right side side board (2,3) and back timber body (1) respectively, the bottom angle of described left and right side side board (2,3) is 0-90 °.
