[0003] The patent with announcement number CN215486094U discloses a fast moving frame structure of tunnel support equipment, which relates to the field of tunnel support. The fast moving frame structure of tunnel support equipment includes a supporting crossbeam frame, a moving assembly and a fixed assembly. The internal sliding connection of the supporting crossbeam frame is provided with two crawlers, and the lower surface of the supporting crossbeam frame is provided with two supporting frames, and the lower surface of the supporting frame is rotatably connected with a fixed seat. The fast moving frame structure of tunnel support equipment drives the two crawlers to slide upward under the action of the moving assembly. When moving to the maximum distance, the two crawlers are attached to the top wall of the tunnel, and the supporting crossbeam frame moves downward at the same time, so that the supporting crossbeam frame is separated from the top wall of the tunnel. At this time, it is convenient for the two crawlers to roll on the top wall of the tunnel, so as to facilitate the rapid movement of the supporting crossbeam frame. However, the support equipment in the prior art cannot support the side wall of the tunnel. If the side wall of the tunnel is uneven, the mechanism for supporting the side wall also needs to be adaptively adjusted in position. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment:

[0026] like Figure 1-5 As shown, a quick support device for shaft and tunnel engineering comprises two columns 1 and a support top frame 2 sliding on the columns 1. The two support top frames 2 are connected by a hinge 3 so that the two support top frames 2 can be folded together to facilitate the folding of the device; a fixing mechanism 4 is arranged between the two support top frames 2. After the two support top frames 2 are rotated and unfolded, the two support top frames 2 can no longer rotate relative to each other through the fixing mechanism 4; a plurality of side support mechanisms 5 are arranged on the column 1. In this embodiment, three side support mechanisms 5 are arranged on a single column 1. The side support mechanism 5 near the supporting top frame 2 is connected to the side wall of the tunnel by fixing bolts 54, and can also provide support for the supporting top frame 2, so that it will not slide off the column 1, and the supporting top frame 2 can support the top wall of the tunnel; the side support mechanism 5 includes a sleeve block 51 sliding on the column 1, and two connecting rods 55 are sliding on the sleeve block 51. The end of the connecting rod 55 close to the side wall of the tunnel is fixedly connected to the side support plate 52, and the side wall of the side support plate 52 away from the hinge 3 is fixedly connected to the connecting plate 53, and the connecting plate 53 is threadedly connected with fixing bolts 54. The connecting plate 53 and the side support plate 52 are connected to the side wall of the tunnel by fixing bolts 54, and each fixing bolt 54 is connected to the side wall of the tunnel, so that the supporting top frame 2 can stably support the top wall of the tunnel.

[0027] like Figure 1-5As shown in the figure, a moving plate 56 is fixedly connected to one end of the connecting rod 55 away from the roadway sidewall. An adjusting bolt 57 is threadedly connected to the moving plate 56. One end of the adjusting bolt 57 close to the sleeve block 51 is rotatably connected to the sleeve block 51 through a bearing seat (not shown in the figure). After the device is unfolded, by rotating the adjusting bolt 57, the moving plate 56 is moved closer to the sleeve block 51, and then the side support plate 52 is moved closer to the roadway sidewall until it contacts the sidewall. After that, the side support mechanism 5 is connected to the roadway sidewall through the fixing bolt 54, so that the side support mechanism 5 supports the roadway sidewall. If the roadway sidewall is uneven, through the cooperation of the adjusting bolt 57, the moving plate 56, the connecting rod 55 and the side support plate 52, the horizontal position of the side support plate 52 in the side support mechanism 5 can be adjusted, and the side support mechanism 5 can support the uneven roadway sidewall.

[0028] As Figure 1-5 shown in the figure, one side of the side support plate 52 close to the roadway sidewall is set to be arc-shaped, and a rubber layer 58 is also provided on the side close to the roadway sidewall. The rubber material can deform under extrusion. By rotating the adjusting bolt 57, the side support plate 52 is moved closer to the roadway sidewall, squeezing the rubber layer 58 to make it adapt to the shape of the roadway sidewall within the support range of the side support plate 52 and providing support for the roadway sidewall, and the rubber layer 58 can also protect the support surface of the side support plate 52.

[0029] As Figure 1-5 shown in the figure, the fixing mechanism 4 includes a first fixing plate 41 fixedly connected to one side support top frame 2 and a second fixing plate 42 fixedly connected to the other side support top frame 2. A sliding frame 43 slides on the first fixing plate 41. The sliding frame 43 is in a C shape. Two through grooves 421 are opened on the second fixing plate 42. Both ends of the sliding frame 43 penetrate and slide in the two through grooves 421. After the two support top frames 2 are unfolded, the sliding frame 43 is pushed so that both ends of it penetrate the two through grooves 421, making the two support top frames 2 unable to rotate relative to each other. After that, when installing the side support mechanism 5, the device can maintain the unfolded state. On the contrary, after the side support mechanism 5 is disassembled, the sliding frame 43 is pulled out of the through groove 421, and the device can be folded for easy transportation.

[0030] As Figure 1-5 shown in the figure, the fixing mechanism 4 further includes a tension spring 44. One end of the tension spring 44 is fixedly connected to the sliding frame 43, and the other end is fixedly connected to the first fixing plate 41. When the tension spring 44 is in the normal state, the end of the sliding frame 43 is just located in the through groove 421. During the unfolding process of the two support top frames 2, the sliding frame 43 is pulled to make the tension spring 44 in a stretched state. After the two support top frames 2 are completely unfolded, the sliding frame 43 is released, and under the pulling force of the tension spring 44 when it restores deformation, the end of the sliding frame 43 slides into the through groove 421, which can improve the installation speed of the device.

[0031] As Figure 1-5As shown, a plurality of diagonal braces 6 are fixedly connected inside the support top frame 2 , and the provision of the diagonal braces 6 can enhance the support stability of the support top frame 2 .

[0032] like Figure 1-5 As shown, the lower end surface of the column 1 is fixedly connected with a bottom plate 7. The bottom plate 7 is provided to increase the contact area between the lower end of the column 1 and the bottom surface of the tunnel, thereby improving the stability of the device.

[0033] The working principle of a quick support device for a shaft and tunnel engineering in this embodiment is as follows: when in use, the device is first transported to a designated position, the two uprights 1 are rotated to unfold the two support frames 2, and before fully unfolding (unfolding to 180 degrees), the sliding frame 43 is pulled to put the tension spring 44 in a stretched state, and after fully unfolding, the sliding frame 43 is released so that the end of the sliding frame 43 can slide into the through groove 421 to complete the fixation of the beam support frame 2; the side support mechanisms 5 adjacent to the support frames 2 are pushed upward until the support frames 2 are in contact with the top wall of the tunnel, and the adjusting bolts 57 are rotated. Make the side support plate 52 contact the side wall of the tunnel and connect the fixing bolt 54 to the side wall of the tunnel, so that the side support mechanism 5 can support the side wall of the tunnel while enabling the supporting top frame 2 to support the top wall of the tunnel. Then, each side support mechanism 5 is connected to the side wall of the tunnel, so that each side support mechanism 5 supports the side wall of the tunnel. Each side support mechanism 5 can adjust the horizontal distance of the side support plate 52 respectively. The side support mechanism 5 can support the uneven side wall of the tunnel. The device is easy to operate during installation, with fewer installation steps, and can be quickly supported.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
