Abstract
The utility model discloses a snapping-preventive device for a two-frame-in-on-group type face end support. The snapping-preventive device comprises a left side beam and a right side beam which are fixedly arranged on a left top beam opposite side and a right top beam opposite side respectively. The left side beam and the right side beam are box-type beams, and a left reinforcement and a right reinforcement are respectively arranged on the lower portions of the left side beam and the right side beam. The snapping-preventive device has the advantages that the side beams are fixedly arranged on the opposite sides of two adjacent support top beams, two supports rest on each other under the interaction of the side beams to avoid snapping, and the snapping-preventive device is simple in structure and convenient to use and has good practical application value.
Description
Technical field
The utility model relates to mining two one group of face end supports, especially relates to a kind of anti-rack device of stinging for two one group of face end supports.
Background technology
Two one group of face end supports are modal a kind of roadway support patterns, owing to be subjected to the influence of roadway floor injustice and set cap discontinuity equalization, cause support integral body to slope inwardly easily, occurring wherein, a back timber gets into below the back timber of another support, thereby two set caps are produced sting the frame phenomenon, cause certain potential safety hazard, gently then cause moving difficulty, heavy then cause the damage of supporting structure spare, bring very big economic loss.
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 prevent that adjacent two stands back timber from producing the anti-rack device of stinging that is used for two one group of face end supports of stinging frame.
For achieving the above object, the utility model can be taked following technical proposals:
The anti-rack device of stinging for two one group of face end supports described in the utility model, it comprises the left and right curb girder that is fixedly installed on left and right back timber opposite side respectively, described left and right curb girder is box beam, and described left and right curb girder lower part is not provided with left and right ribs.
Sidewall at described left side beam is respectively arranged with left upper ear seat and left lower ear base; Sidewall at described right side beam is respectively equipped with right upper ear seat and right lower ear base.
The utility model advantage is to fixedly install curb girder by the opposite side at adjacent two stands back timber, and under the interaction of curb girder, two supports rely on mutually and are unlikely to cause and sting frame, and this apparatus structure is simple, and is easy to use, has good actual application and is worth.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the anti-rack device of stinging for two one group of face end supports described in the utility model, it comprises the left and right curb girder 3,4 that is fixedly installed on left and right back timber 1,2 opposite sides respectively, described left and right curb girder 3,4 is box beam, and described left and right curb girder 3,4 bottoms are respectively equipped with left and right ribs 5,6.In use be convenient left and right curb girder 3,4 dismounting and installation, be respectively arranged with left upper ear seat 7 and left lower ear base 8 at the sidewall of described left side beam 3, and be connected with left back timber 1 by bearing pin respectively; Sidewall at described right side beam 4 is respectively equipped with right upper ear seat 9 and right lower ear base 10, and is connected with right back timber 2 by bearing pin respectively.
