Therefore, the two ends of the arched beam 10 in the embodiment of the present application, specifically, any portion of the arched beam 10 far away from the middle in the arch changing direction, can ensure that the contact area between the carrying member 30 disposed on the outer side surface of the arched beam 10 and the vertically upward supporting column 40 is the largest, and the bottom surface of the carrying member 30 faces vertically downward to the horizontal plane of the tunnel. The stress centers of the carrying piece 30 and the supporting column 40 are ensured to be on a straight line vertical to the horizontal plane of the tunnel, so that the phenomenon that the supporting column 40 of the supporting equipment is unbalanced load is avoided, and the stability of the supporting equipment is influenced.

The situation that the existing arched beams are required to be replaced together when the mechanical property of the supporting columns with the existing specification cannot meet the requirement of effectively supporting the supporting equipment is avoided, so that the application scene of the supporting equipment is expanded, and the use cost of the supporting equipment is reduced. In addition, in the radial plane of the arched beam 10, the carrying members at the two ends of the arched beam 10 are symmetrically arranged about the perpendicular bisector D of the arched beam 10, so that the number and the positions of the carrying members 30 at the two ends of the arched beam 10 are consistent, the structural symmetry of the supporting equipment is improved, the unbalanced loading phenomenon of the supporting columns is effectively avoided, and the stability of the supporting equipment is improved.

To enhance the stability of the support apparatus, support columns 40 of the prior art that are directly connected to the arched beams may be retained. If the support column 40 attached to the arm 30 has met the requirements for supporting the support apparatus, a telescoping column 50 can be used in place of the support column 40 attached to the arched beam, where the telescoping column 50 serves as a guide for the support column 40 attached to the arm 30.

By providing a connecting beam, connecting the plurality of arched beams 10 and the side wing beams 20 enhances the integrity and stability of the support apparatus.
By applying the embodiment of the application, at least the following beneficial effects can be realized:
1. according to the supporting device provided by the embodiment of the application, the carrying pieces are arranged on the outer side face of the arched beam, and in the radial plane of the arched beam, the carrying pieces at the two ends of the arched beam are symmetrically arranged relative to the perpendicular bisector of the arched beam, and the supporting columns are directly connected with the carrying pieces. The diameter specification of the support column is prevented from being limited by the size specification of the arched beam, so that the selection of the support column of the supporting equipment is enriched, the application scene of the supporting equipment is expanded, and the phenomenon that the support column is unbalanced loaded is effectively prevented, and the stability of the supporting equipment is influenced.
2. The mounting sleeve 31 is arranged to enable the carrying piece 30 to be detachably connected with the supporting column 40, so that the mounting and the use of the supportable equipment are convenient. Meanwhile, the peripheral wall of the mounting sleeve 31 is in contact with the support column 40, so that the contact area between the carrying piece 30 and the support column 40 is increased, the peripheral wall of the mounting sleeve 31 plays a role in supporting the surrounding support column 40, and the stability of supporting equipment is further improved.
3. In the supporting device provided by the embodiment of the application, the side wing beams or the side members are arranged on the outer side faces of the arched beams, and in the radial plane of the arched beams, the side members arranged on the side wing beams or the arched beams are symmetrically arranged about the center vertical line of the arched beams, and the supporting columns are directly connected with the side members. The diameter specification of the support column is prevented from being limited by the size specification of the arched beam, so that the selection of the support column of the supporting equipment is enriched, the application scene of the supporting equipment is expanded, and the phenomenon that the support column is unbalanced loaded is effectively prevented, and the stability of the supporting equipment is influenced.
