DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Reference Figure 1-3 , a geological exploration anti-collapse equipment, including a support frame, the support frame includes a bottom plate 1, a support plate 2 located above the bottom plate 1, and a plurality of support columns 3 fixedly connected between the bottom plate 1 and the support plate 2, the top of the support plate 2 is fixedly connected to a top plate 5 through a plurality of vibration reduction mechanisms, the lower surface of the top plate 5 is fixedly connected to a transmission rod 6 with the same number as the support column 3, a connecting seat 7 is slidably installed on the side of each support column 3, the bottom end of each transmission rod 6 respectively penetrates the support plate 2 downward and is slidably installed in the sliding hole at the top of the corresponding connecting seat 7, the transmission rod 6 and the support plate 2 can slide relatively, a first spring 8 is fixedly connected between the bottom wall of the sliding hole and the bottom end of the transmission rod 6, side plates 9 are respectively arranged on both sides of the support frame, the top and bottom of the side plate 9 close to the support frame are fixedly connected to guide columns 10, the other ends of the two guide columns 10 are respectively slidably installed inside the bottom plate 1 and the support plate 2, and a plurality of connecting rods 12 are hinged between each connecting seat 7 and the corresponding side plate 9.

[0022] In this embodiment, a vertical slide groove 13 with a T-shaped cross section is provided on the side of the support column 3, and a slider with a T-shaped cross section is provided on the side of the connecting seat 7 close to the support column 3, and the slider is slidably installed in the vertical slide groove 13. The cross sections of the vertical slide groove 13 and the slider are both T-shaped, which can reliably ensure the smoothness of the sliding of the connecting seat 7.

[0023] In this embodiment, the upper surface of the top plate 5 is an upwardly protruding spherical surface, which can facilitate full contact with the top wall of the tunnel, and the setting of the spherical surface can effectively disperse the load it bears, thereby ensuring its strength and stability. The lower surface of the top plate 5 is a plane.

[0024] In this embodiment, the vibration reduction mechanism adopts a spring vibration reduction device 4 .

[0025] In this embodiment, one end of each connecting rod 12 is hinged to the side of the side plate 9, and the other end is hinged to the side of the connecting seat 7, and two adjacent connecting rods 12 are arranged parallel to each other, thereby ensuring the consistency of the movement of the connecting rods 12.

[0026] In this embodiment, a second spring 11 is sleeved on the guide column 10 located between the side plate 9 and the bottom plate 1 and on the guide column 10 located between the side plate 9 and the support plate 2. One end of the second spring abuts against the side surface of the bottom plate or the support plate, and the other end abuts against the side plate. The second spring 11 can provide elastic support for the side plate 9, so that the side plate 9 can provide support for the side wall of the tunnel.

[0027] In this embodiment, a pressing column 15 is fixedly connected to the middle of the lower surface of the top plate 5, a pressing switch 14 is installed on the upper surface of the support plate 2 just below the pressing column 15, and an alarm 16 is fixedly connected to the lower surface of the support plate 2, and the pressing switch 14 is electrically connected to the alarm 16. When the top of the tunnel collapses seriously, the top plate 5 will drive the pressing column 15 to move downward and trigger the pressing switch 14, at which time the alarm 16 can sound an alarm to remind the staff to evacuate quickly.

[0028] In this embodiment, a lifting mechanism is fixedly connected to the bottom end of the bottom plate for lifting the bottom plate, and the lifting mechanism includes a base 17 and a plurality of hydraulic cylinders 18, the base is located directly below the bottom plate, and the plurality of hydraulic cylinders are fixedly connected between the bottom plate and the base. After the device is moved to a position where support is required, the bottom plate and the structure above the bottom plate can be lifted by adjusting the hydraulic cylinders, so that the top plate can fully contact the top wall of the tunnel and provide support force, that is, the setting of the lifting mechanism enables the device to adapt to tunnels of different heights.

[0029] In this embodiment, a plurality of spike-shaped protrusions 20 are evenly arranged on the lower surface of the base 17. When the spike-shaped protrusions are in close contact with the ground, the friction between the base and the ground can be increased, thereby preventing the anti-collapse device from moving.

[0030] In this embodiment, a plurality of threaded holes are provided on the base 17, and an anchor bolt 19 is threadedly connected in each threaded hole. The anchor bolt is used to fix the base to the ground, thereby further improving the stability of the device and preventing the device from accidentally moving.

[0031] The working principle of the present invention is:

[0032] The top plate 5 of the present invention can provide elastic support for the tunnel top under the action of the spring shock absorber, and the side plate 9 can provide elastic support for the tunnel side wall under the action of the second spring 11. When the tunnel top collapses slightly or a small amount of soil falls, the top plate 5 is compressed and pushes the transmission rod 6 to move downward, and the transmission rod 6 pushes the connecting seat 7 to move downward through the first spring 8. At this time, the angle between the connecting rod 12 and the connecting seat 7 tends to gradually increase, thereby pushing the side plate 9 to press the tunnel side wall. At this time, the inverse force of the tunnel side wall on the side plate 9 can be re-transmitted to the top plate 5 through the above structure. When the tunnel side plate 9 collapses, the force transmission direction is opposite, that is, the present device can enable the tunnel side wall and the top wall to provide support to each other; when the tunnel top collapses seriously, the top plate 5 moves downward excessively, and the first spring 8 is compressed to the extreme. At this time, the pressing column 15 contacts the pressing switch 14, and the alarm 16 sounds an alarm to remind the staff to evacuate quickly.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
