[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] like Figure 1 As shown, a multifunctional platform for storing and transporting tunnel steel arch frames includes two longitudinal bars 1 and two transverse bars 2. The two longitudinal bars 1 and the two transverse bars 2 form a square frame structure, with the two ends of the transverse bars 2 located outside the longitudinal bars 1. The ends of the transverse bars 2 are respectively provided with lifting ears 6, and the lifting ears 6 are provided with lifting buckles 7. The square frame is provided with a leg 4 at the bottom of each of the four right angles. Among the four legs 4, the bottoms of the two legs 4 corresponding to one longitudinal bar are respectively detachably mounted with universal brake wheels 8, and the bottoms of the two legs 4 corresponding to the other longitudinal bar are respectively detachably mounted with fixed wheels 9. The movement direction of the universal brake wheels 8 and the fixed wheels 9 is the same as the arrangement direction of the transverse bars 2.

[0024] The two crossbars 2 are each provided with an anti-slip limit sleeve 5 on the outside. The anti-slip limit sleeve 5 is evenly provided with a number of limit rings 10 in the axial direction. The spacing between the limit rings 10 corresponds to the width of the steel arch frame. The limit rings 10 on the two crossbars 2 are provided in a one-to-one correspondence. The anti-slip limit sleeve 5 includes a sleeve body, which is preferably a metal part and is fixed axially relative to the crossbar 2. For example, the length of the anti-slip limit sleeve 5 corresponds to the length of the crossbar 2 between the two longitudinal bars 1, so that the two ends of the anti-slip limit sleeve 5 abut against the longitudinal bar 1, and the anti-slip limit sleeve 5 is limited axially. Alternatively, the anti-slip limit sleeve 5 and the crossbar 2 can be directly connected and fixed, such as by providing through holes at both ends of the crossbar and the sleeve body, and fixing the sleeve body and the crossbar 2 by a pin. The limit ring 10 is provided on the sleeve body, and the sleeve body is wrapped with an anti-slip pad layer at the position between each two adjacent limit rings 10. The anti-slip pad layer can be a rubber pad layer or a straw rope winding structure. Two adjacent limiting rings 10 axially limit the position of the steel arch frame, and the steel arch frame is supported by two cross bars 2 after being placed. Figure 2 、 Figure 3 As shown, the steel arches are arranged neatly. The anti-skid pads on the crossbar 2 prevent the steel arches from directly colliding with the crossbar 2 and preventing the supporting steel from being damaged.

[0025] In the present invention, the support leg 4 is a tube structure, and the connection structure between the universal brake wheel 8 and the support leg 4 is as follows: Figure 4 As shown, the connection structure between the directional wheel 9 and the support leg 4 is as shown in FIG. Figure 5As shown, the diameters of the plug-in joints 12 at the top of the universal brake wheels 8 and the plug-in joints 12 at the top of the directional wheels 9 are respectively same as the inner diameters of the corresponding supporting legs 4, and the supporting legs 4, the plug-in joints 12 at the top of the universal brake wheels 8 and the plug-in joints 12 at the top of the directional wheels 9 are respectively provided with through holes in the transverse direction, the plug-in joints 12 of the universal brake wheels 8 and the plug-in joints 12 of the directional wheels 9 are respectively inserted into the corresponding supporting legs 4, the bolt 11 is transversely inserted into the through holes of the plug-in joints 12 and the supporting legs 4, and the bolt is fixed by the nut.

[0026] The universal brake wheels 8, the directional wheels 9 and the supporting legs can also be connected in the following manner, a flange is arranged at the bottom of each supporting leg 4, and the supporting leg 4 is connected with the corresponding universal brake wheel 8 and the corresponding directional wheel 9 through the flange.

[0027] A fixed rod 3 is arranged above each supporting leg 4, the diameter of the fixed rod 3 is corresponding to the inner diameter of the supporting leg 4, and the length of the fixed rod 3 is less than the length of the supporting leg 4. The mechanism realizes the up-down stacking of multiple racks, as shown in the following figure. Figure 6 When two racks are stacked, the four fixed rods 3 of the lower rack are inserted into the four supporting legs 4 of the upper rack, and the four supporting legs 4 of the upper rack abut against the square frame of the lower rack.

[0028] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
