[0043] ​​​​For better explaining the utility model, in order to facilitate understanding, below combining with the drawings, through specific embodiment, the utility model is described in detail.The orientation mentioned in this article is with reference to the orientation of the sleeve 1. Figure 1

[0044] Embodiment 1

[0045] Referring to Figure 1 And 2 The utility model embodiment proposes roadway support including the sleeve 1 of vertical orientation, upper jack 2 and lower jack 3.

[0046] The sleeve 1 of vertical orientation can be connected on the transfer machine 200.The main body of upper jack 2 and lower jack 3 is oppositely arranged and is respectively inserted in the upper portion and lower portion of sleeve 1, and the extending end of upper jack 2 and lower jack 3 can be telescopic relative to sleeve 1, so that roadway support 100 is in the state of jacking or movable.

[0047] When the extending end of upper jack 2 and lower jack 3 is all elongated relative to sleeve 1 and respectively jacks the roof and floor of roadway, roadway support 100 is in the state of jacking.

[0048] When the extending end of upper jack 2 is contracted relative to sleeve 1 and is separated from the roof of roadway, roadway support 100 is in the movable state.

[0049] When the extending end of upper jack 2 and lower jack 3 is all elongated relative to sleeve 1 and respectively jacks the roof and floor of roadway, roadway support 100 is in the state of jacking, to realize the support of the roof of roadway of the working face where the transfer machine 200 is.When the extending end of upper jack 2 is contracted relative to sleeve 1 and is separated from the roof of roadway, to make roadway support 100 cancel the jacking of the roof of roadway, roadway support 100 is in the movable state, and roadway support 10 is driven by the transfer machine 200 and is synchronously moved forward, so that the worker does not need to carry roadway support 10, the labor intensity is reduced, and the moving efficiency of roadway support 10 can be improved.

[0050] It should be noted that when the extending end of upper jack 2 is contracted relative to sleeve 1 and is separated from the roof of roadway, and the extending end of lower jack 3 is only contracted and abuts against the floor of roadway and is not separated from the floor of roadway, the transfer machine 200 can still drive roadway support 10 to normally and synchronously move forward.

[0051] Preferably, when the extending end of upper jack 2 and lower jack 3 is all contracted relative to sleeve 1 and is respectively separated from the roof and floor of roadway, roadway support 100 is in the movable state, so that the transfer machine 200 can more smoothly drive roadway support 10 to synchronously move forward.

[0052] ​Further, the sleeve 1 can drive the upper and lower jacks 2 and 3 to rotate the transfer machine 200 around the vertical axis, so that the upper jack 2 can avoid the obstacles such as the steel mesh on the roadway roof.

[0053] Further, the roadway support 100 further comprises a horizontally oriented connecting frame 4.

[0056] Since the retracting stroke of the extending end of the lower jack 3 is limited, when the roadway support 100 is in a movable state and moves forward along the roadway with the transfer machine 200 to the roadway floor with a higher height, only by retracting the extending end of the lower jack 3 upward, the extending end of the lower jack 3 can still be below the top of the roadway floor, hindering the forward movement of the roadway support 100. At this time, the roadway floor in contact with the extending end of the lower jack 3 will push the lower jack 3 upward, and the lower jack 3 drives the whole roadway support 100 to rise relative to the connecting frame 4, so that the extending end of the lower jack 3 can be flush with or higher than the roadway floor, and the transfer machine 200 can smoothly drive the roadway support 100 to move forward.

[0057] Further, the roadway support 100 further comprises a support frame 7.

When supporting the roof of the roadway, the disc 23 can rotate about the horizontal axis and drive the plurality of conical bodies 24 thereon to adapt to support the uneven roof of the roadway.

[0067] More specifically, the bottom of the disc 23 is fixedly connected to a disc frame body, and the disc frame body and the extending end of the upper jack 2 are rotationally connected through a horizontally oriented second pin shaft 62, so that the disc 23 can rotate about the horizontal axis relative to the upper jack 2.

[0068] Further, the output end of the lower jack 3 is rotationally connected to a support seat 33 about a horizontal axis, and the bottom of the support seat 33 is a flat supporting surface. When supporting the floor of the roadway, the support seat 33 can rotate about the horizontal axis to adapt to support the uneven floor of the roadway.

[0069] Specifically, the output end of the lower jack 3 and the support seat 33 are rotationally connected through a horizontally oriented third pin shaft 63, so that the support seat 33 can rotate about the horizontal axis relative to the output end of the lower jack 3.
