[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Combine the following Figures 1 to 4 The utility model is described in detail.

[0023] A rib mounting bracket platform includes a bracket 1, a support rod 101 is arranged on the top of the bracket 1, a support ring 2 is connected to the top of the support rod 101, a limiting rod 1011 is arranged on one side of the support rod 101, a limiting disk 1012 is arranged at one end of the limiting rod 1011, and deflection assemblies are arranged at both ends of the support ring 2, and the deflection assemblies drive the support ring 2 to move along the axis.

[0024] First, the steel pipe arch is placed on the support ring 2 on the bracket 1 in sequence to support and place the steel pipe arch, so as to facilitate the lifting equipment to lift it, and there is no need to perform operations such as flipping it.

[0025] At the same time, when the steel tube arch is placed on the support ring 2 for preliminary assembly through hoisting, it will first contact the top part of the support ring 2, and then through the gravity below the steel tube arch, force the support ring 2 to deflect along the movable axis 202 on the connecting blocks 201 at both ends when under pressure, until the lower half of the support ring 2 also fits to the bottom of the steel tube arch for fit support, so that the support ring 2 can be used for steel tube arches with different curvatures to fit and support them, making it more versatile.

[0026] Furthermore, the limiting rod 1011 penetrates the outer shell of the support rod 101 and extends into the internal cavity of the support rod 101. The limiting rod 1011 protrudes from the support rod 101 and is threadedly connected with a pin at one end. The limiting disk 1012 also includes a limiting ratchet block 1013. The limiting ratchet block 1013 is a plurality of arc-shaped protrusions hingedly connected to the side wall of the limiting disk 1012. The deflection assembly includes a connecting block 201, a movable shaft 202 and a limiting groove 203. The connecting block 201 is arranged at both ends of the support ring 2, and the movable shaft 202 is arranged It is arranged on one side of the connecting block 201, and the limiting groove 203 is arranged on the side wall of the movable shaft 202. The movable shaft 202 is a round shaft protrusion protruding from one side of the connecting block 201 and penetrating the outer shell of the support rod 101 for connection, and the movable shaft 202 partially protrudes in the internal cavity of the support rod 101. The movable shaft 202 and the limiting disk 1012 are staggered up and down, and the limiting groove 203 is a groove that cooperates with the side wall of the movable shaft 202 and the limiting ratchet block 1013, and the bottom opening side of the limiting groove 203 is an inclined surface that is obliquely extended.

[0027] After the support ring 2 is deflected to a suitable angle and fits the steel pipe arch as closely as possible, the limiting rod 1011 that passes through the outer shell of the support rod 101 is controlled to be pushed in axially, so that the limiting rod 1011 will extend into the cavity in the support rod 101 when pushed in, thereby driving the limiting disk 1012 to approach the part of the movable shaft 202 protruding in the cavity. When the two are close and fit together, the limiting ratchet block 1013 will be embedded in the limiting groove 203, and then through continuous rotation, if the limiting ratchet block 1013 is not aligned with the limiting groove 203, Adjust them to fit together, and then after the two are fully fitted together, rotate the pin through it to cooperate with the groove on the side wall of the support rod 101, so that the limiting rod 1011 is rotated to prevent it from rotating on its own, and then the movable shaft 202 is limited by the limiting ratchet block 1013 to prevent the movable shaft 202 from rotating on its own, thereby creating a certain obstacle to the movable shaft 202. At the same time, when the support ring 2 itself completes the placement of the steel pipe arch and fits it fully, the weight of the support ring 2 will not easily deflect, and it will be in an arc shape after the initial splicing.

[0028] The following is a specific implementation process of the utility model. First, when the steel tube arch is placed on the support ring 2 for preliminary assembly through hoisting, it will first contact the top part of the support ring 2, and then through the gravity below the steel tube arch, it will force the support ring 2 to deflect along the movable axis 202 on the connecting blocks 201 at both ends when under pressure, until the lower half of the support ring 2 also fits against the bottom of the steel tube arch for fit support, so that the support ring 2 can be used for steel tube arches with different curvatures to fit and support them, making it more versatile. After the support ring 2 is deflected to a suitable angle and fits the steel tube arch as closely as possible, the limiting rod 1011 that passes through the outer shell of the support rod 101 is controlled to be pushed axially, so that the limiting rod 1011 will extend into the cavity in the support rod 101 when pushed in, thereby driving the limiting plate 1012 to move closer. The movable shaft 202 protrudes from the cavity, and when the two are brought close to fit together, the limiting ratchet block 1013 will be embedded in the limiting groove 203, and then through continuous rotation, if the position of the limiting ratchet block 1013 is not aligned with the limiting groove 203, it will be adjusted to fit together, and then after the two are fully fitted, the pin is rotated through and cooperates with the groove on the side wall of the support rod 101, so that the limiting rod 1011 is rotated to prevent it from rotating on its own, and then the movable shaft 202 is limited by the limiting ratchet block 1013 to prevent the movable shaft 202 from rotating on its own, which creates a certain obstacle to the movable shaft 202. At the same time, when the support ring 2 itself completes the placement of the steel pipe arch and fits fully, it will not easily deflect due to the pressure of the weight, and it will be in an arc shape after the initial splicing.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
