The supporting frame is characterized in that a first supporting beam 1, a second supporting beam 2, one or more supporting upright posts 3, one or more upright post sliding devices 4 and one or more side pushing jacks 8 can form a relatively independent supporting frame for supporting a roadway roof rock stratum; a plurality of relatively independent support frames can form a support frame group to support the roadway roof in a large range.
Specifically, because the column sliding devices 4 mainly drive the support columns 3 to move, the number of the support columns 3 is the same as that of the column sliding devices 4.
In one embodiment, the first support beam 1 comprises a first support beam sliding box body 11, a first support beam rib plate 12, a first support beam hinge box body 13, a first support beam hinge seat 14 and a first support beam support guard plate 15, which is shown in fig. 6.

The first supporting beam 1 is hinged to the second supporting beam 2 through the first supporting beam hinging seat 14 and the second supporting beam hinging seat 24, two ends of the side-pushing jack 8 are hinged to the first supporting beam 1 and the second supporting beam 2 respectively, and the side-pushing jack 8 can enable the first supporting beam 1 and the second supporting beam 2 to rotate relatively through stretching and retracting actions, as shown in fig. 8.
The column sliding device 4 comprises a roller 41, a supporting plate 42, a supporting plate 43 and a supporting column hinge lug plate 44, as shown in fig. 9, the roller 41 can roll on the first supporting beam sliding box body 11 and the second supporting beam sliding box body 21, the supporting plate 43 is used for transmitting the supporting force of the supporting column 3 to the first supporting beam 1, effective supporting of a roadway roof rock stratum is achieved, and the supporting column hinge lug plate 44 is hinged with the supporting column 3, so that the supporting column 3 is driven to move.
Specifically, when the support upright 3 applies support force to the support plate 43, the support plate 43 is in close contact with the first support beam sliding box body 11, and the roller 41 is separated from the first support beam sliding box body 11, so that effective support of a roadway roof rock stratum is realized; when the supporting upright post 3 shrinks and is separated from the roadway bottom plate, the supporting plate 43 is separated from the first supporting beam sliding box body 11, the roller 41 is contacted with the first supporting beam sliding box body 11, and the upright post sliding device 4 can drive the supporting upright post 3 to move.

The sliding track 7 comprises a sliding bottom support plate 71 and a column supporting track 72, which is shown in fig. 11.
Specifically, when a relatively independent support frame is moved, the moving space of the haulage roadway is very narrow due to the fact that partial space in the middle of the haulage roadway is occupied by a reversed loader, a crusher, an equipment train and the like, and the support devices can only be arranged on two sides of the roadway; in order to prevent the relatively independent support frame which is moved in the moving process from interfering with other support frames in a supporting state, the top beam supporting and moving device sliding box 26 must be arranged on the side close to the roadway side; because the gravity center of a relatively independent support frame is not at the position of the top beam supporting and moving device sliding box body 26, the relatively independent support frame is necessarily inclined only by utilizing the top beam supporting and moving device 5 to move the relatively independent support frame, and the strength of the top beam supporting and moving device 5 is difficult to meet the requirement of supporting the relatively independent support frame, so that the support upright post 3 is placed on the upright post supporting and moving frame 61 after being contracted, the weight of the support frame is balanced, and the top beam supporting and moving device 5 and the upright post supporting and moving device 6 are utilized to move the relatively independent support frame.
