Moreover, the cross beam and the longitudinal beam are both set as multi-section hinged structures, which can better adapt to the structure at the top of the roadway and can better provide support force to the top of the roadway. The utility model will be introduced in detail below in combination with specific embodiments:

[0031] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 3 The utility model provides a self-moving type row support, which comprises a first support 10 and a second support 20, the first support 10 and the second support 20 are connected through a telescopic device 30, the telescopic device 30 can drive the first support 10 or the second support 20 to move through telescopic action, and the self-moving of the row support can be realized through the alternate movement of the first support 10 and the second support 20.

[0032] The first support 10 and the second support 20 both comprise a cross beam 1, a longitudinal beam 2 and a support column 3, the longitudinal beam 2 is connected below the cross beam 1, the support column 3 is a telescopic structure, and the first support 10 or the second support 20 can be moved by controlling the contraction of the support column 3 of the first support 10 or the second support 20. The telescopic device 30 is arranged between the first support 10 and the second support 20 and is connected with one cross beam 1 or longitudinal beam 2 on the first support 10 and the second support 20 respectively.

[0033] Two ends of each of the cross beams 1 are connected with a support column 3, and the longitudinal beams 2 are arranged in parallel to each other and at least two of the longitudinal beams 2 are arranged close to the two ends of the cross beams 1. In the embodiment, two longitudinal beams 2 are arranged, and more longitudinal beams 2 can be arranged according to the length of the cross beams 1. Optionally, the support column 3 is a hydraulic cylinder which is connected with the cross beam 1 perpendicularly at the end of the cross beam 1. When the support column 3 is extended, the cross beam 1 can be supported to contact with the roof of the tunnel and play a supporting role. When the support column 3 is retracted, the cross beam 1 can be lowered to separate from the tunnel, and then can be moved under the action of the telescopic device 30. Optionally, the bottom end of the support column 3 is provided with a support base 4 to increase the contact area with the ground and avoid sinking into the ground. The top end of the support column 3 is fixedly connected with the cross beam 1, or the top end of the support column 3 is hingedly connected with the cross beam 1, so that the angle between the support column 3 and the cross beam 1 can be adjusted within a certain range to better adapt to different positions in the tunnel. Further, when the top end of the support column 3 is hingedly connected with the cross beam 1, the bottom end of the support column 3 is also hingedly connected with the support base 4, so that the support base 4 can be completely in contact with the ground.

[0034] Optionally, at least two cross beams 1 are arranged on the first support 10 and the second support 20, and the distance between the two adjacent cross beams 1 matches the row spacing of the anchor rods, for example, is the same as or an integer multiple of the row spacing of the anchor rods. Optionally, the distance between the two adjacent cross beams 1 is 1-5 times the row spacing of the anchor rods. The common row spacing of the anchor rods is 0.5-1.5 m. In particular, when the steel belt 40 is arranged on the roof of the tunnel, the row spacing of the steel belt 40 is the row spacing of the anchor rods. For example, as shown in FIG. 4, the distance between the two cross beams 1 is the same as the row spacing of the steel belt 40 or three times or four times the row spacing of the steel belt 40, so that the steel belt 40 is located between the two cross beams 1 and does not interfere with the cross beams 1. Figure 4

[0035] In some embodiments, as shown in FIG. 5, the first support 10 and the second support 20 are arranged on the same side of the tunnel, and the cross beams 1 are arranged on the same side of the tunnel. Figure 3 ​As shown, two longitudinal beams 2 are arranged on the first support 10 and the second support 20, and are arranged perpendicularly to the cross beam 1 and at positions close to the two ends of the cross beam 1, and are located between the two support columns 3.

Optionally, a connecting seat 21 is arranged on the bottom surface of the cross beam 1, and the longitudinal beam 2 is connected to the connecting seat 21, and in the supporting state, due to the connection between the longitudinal beam 2 and the connecting seat 21, there is a certain distance between the cross beam 1 and the longitudinal beam 2, and when it is necessary to move, the cross beam 1 on one of the supports is lowered to fall on the longitudinal beam 2 of the other support, and the other support is supported by the support.

[0036] In some embodiments, gaps are formed between the adjacent longitudinal beams 2 on the first support 10 and the second support 20, and the telescopic devices 30 are arranged between the longitudinal beams 2 of the first support 10 and the longitudinal beams 2 of the second support 20, that is, the telescopic devices 30 are arranged in the gaps formed between the adjacent longitudinal beams 2 of the first support 10 and the second support 20, and are connected to the two longitudinal beams 2 at the same time. Optionally, the telescopic device 30 is a hydraulic telescopic cylinder, and one connecting support 31 is arranged on each of the two longitudinal beams 2, and the telescopic device 30 is connected to the two connecting supports 31. The telescopic device 30 is arranged between the longitudinal beams 2 of the first support 10 and the second support 20 and is connected to the longitudinal beams 2, which can avoid occupying the internal space of the self-moving row support, and will not affect the construction in the self-moving row support, and at the same time, it is convenient to provide driving force for the movement of the first support 10 and the second support 20. Optionally, two telescopic devices 30 are arranged, and the two telescopic devices 30 are symmetrically distributed on the two sides of the two longitudinal beams 2 of the second support 20 and are connected to the longitudinal beams 2 of the first support 10 and the second support 20 at the same time, and the two telescopic devices 30 act synchronously, so that the movement of the first support 10 and the second support 20 is more stable. In other embodiments, the telescopic device 30 can also be arranged in multiple, such as four, six, etc., and is distributed along the length direction of the longitudinal beam 2 on the two sides of the two longitudinal beams 2 of the second support 20.

[0037] In some embodiments, the telescopic device 30 can also be arranged between the two adjacent cross beams 1 on the first support 10 and the second support 20 and be connected to the two cross beams 1 respectively. Optionally, the telescopic device 30 is located between the two cross beams 1 and is connected to the bottom surface of the cross beam 1, so as to avoid affecting the support of the cross beam 1 to the top of the roadway. The telescopic device 30 can be one or more.

[0038] In some embodiments, the longitudinal beam 2 comprises at least two sections connected by a hinged structure, and the longitudinal beam 2 is a multi-section hinged structure, so that the height of the transverse beam 1 at different positions in the longitudinal direction can be different, thereby ensuring that each transverse beam 1 can effectively support the roof of the tunnel.

[0039] Optionally, the transverse beam 1 comprises at least two sections connected by a hinged structure, and the transverse beam 1 is a multi-section hinged structure, so that the transverse beam 1 can be deformed in the transverse direction, thereby adjusting the two ends of the transverse beam 1 by the supporting columns 3 to ensure that the two ends of the transverse beam 1 can effectively support the roof of the tunnel.

[0040] In some embodiments, the first support 10 is provided with a roller at the bottom of the position opposite to the longitudinal beam 2 of the second support 20, and the second support 20 is provided with a roller at the bottom of the position opposite to the longitudinal beam 2 of the first support 10, and the rollers roll in contact with the longitudinal beam 2 when the first support 10 or the second support 20 moves. Since the longitudinal beam 2 is connected to the bottom surface of the transverse beam 1 by the connecting seat 21, the transverse beam 1 and the longitudinal beam 2 on the same support have a certain height difference, and the height difference is greater than the height of the roller, so that the first support 10 or the second support 20 can have a certain descending space when moving, i.e. the height difference between the roller and the longitudinal beam 2 on the other support, thereby ensuring that the transverse beam 1 can be lowered to separate from the roof of the tunnel when the first support 10 or the second support 20 moves, so that the first support 10 or the second support 20 can move smoothly. At the same time, the provision of the roller can reduce the resistance when moving, and change the sliding contact into rolling contact.

[0041] The moving mode of the self-moving type row support provided by the utility model comprises:

[0042] The supporting column 3 of the second support 20 is retracted, the transverse beam 1 of the second support 20 is lowered and in contact with the longitudinal beam 2 of the first support 10, or in contact with the longitudinal beam 2 of the first support 10 through the roller. Then the telescopic device 30 is controlled to retract, so that the second support 20 moves like the front, and after the second support 20 is moved to the position, the supporting column 3 of the second support 20 is lengthened, so that the transverse beam 1 of the second support 20 is in contact with the roof of the tunnel and provides support. Then the supporting column 3 of the first support 10 is retracted, so that the transverse beam 1 of the first support 10 is lowered and in contact with the longitudinal beam 2 of the second support 20, or in contact with the longitudinal beam 2 of the second support 20 through the roller. Then the telescopic device 30 is controlled to lengthen, so that the first support 10 moves like the front, and after the first support 10 is moved to the position, the supporting column 3 of the first support 10 is lengthened, so that the transverse beam 1 of the first support 10 is in contact with the roof of the tunnel and provides support, thereby completing one movement.
