Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , an embodiment provided by the present invention: a tunnel structure safety protection device, including a ground rail 1, a first protective shed 2 and a second protective shed 3. On both sides of the bottom end of the first protective shed 2, two first support rods 9 are symmetrically and fixedly connected respectively. At the bottom end of the first support rod 9, a first chute 10 is opened. Between the two first support rods 9 on the same side of the first protective shed 2, support rods 11 are evenly and fixedly connected. The support rods 11 are used to support the strength of the first support rods 9. On both sides of the bottom end of the first protective shed 2, side protective plates 12 are fixedly connected respectively. The side protective plates 12 are used to block the soil and stones on the side. Both ends of the side protective plates 12 are fixedly connected to the first support rods 9 respectively. At one end of the top end of the first protective shed 2, a top clamping strip 14 is fixedly connected. On the outer sides of the two first support rods 9 of the first protective shed 2 close to the top clamping strip 14, outer clamping strips 13 are fixedly connected respectively.

[0021] The second protective shed 3 is arranged at one end of the first protective shed 2 close to the top clamping strip 14. Both the first protective shed 2 and the second protective shed 3 are designed to bulge upward in an arc shape. The arc design can make the crushed stones falling on the top ends of the first protective shed 2 or the second protective shed 3 slide to both sides, avoiding accumulation and crushing the first protective shed 2 or the second protective shed 3. And on both sides of the bottom end of the second protective shed 3, there are protective layers the same as the support rods 11 and the side protective plates 12. At both ends of the bottom end of the second protective shed 3, bottom clamping strips 17 are fixedly connected respectively. On both sides of the bottom end of the second protective shed 3, two second support rods 15 are symmetrically and fixedly connected respectively. On the inner sides of the two second support rods 15 of the second protective shed 3 close to the first protective shed 2, inner clamping strips 16 are fixedly connected respectively. At the bottom end of the second support rod 15, a second chute 18 is opened.

[0022] There are two ground tracks 1 symmetrically arranged. On one side of the inner top end of the ground track 1, a first slide rail 4 is fixedly connected, and on the other side of the inner top end of the ground track 1, a second slide rail 5 is fixedly connected. One end of the ground track 1 is fixedly connected with a pull ring 6. By applying a traction force to the pull ring 6, the ground track 1 is pulled to move. On one side of the top end of the ground track 1, two mounting plates 7 are symmetrically and fixedly connected. Between the two ground tracks 1, two connecting fixing plates 8 are symmetrically arranged. The two ends of the connecting fixing plate 8 are respectively fixedly installed at the bottom ends of the mounting plates 7 on the two ground tracks 1 through bolts. The two ground tracks 1 are connected and fixed by the connecting fixing plate 8, so that the two ground tracks 1 are kept balanced.

[0023] The first protective shed 2 is slidably connected to the first slide rail 4 through a first chute 10 opened at the bottom end of the first support rod 9. The second protective shed 3 is slidably connected to the second slide rail 5 through a second chute 18 opened at the bottom end of the second support rod 15. The first protective shed 2 is arranged inside the second protective shed 3. The top strip 14 is located between the two bottom strips 17, and the top strip 14 is in contact connection with the two bottom strips 17 respectively. The top end of the top strip 14 is lower than the bottom end of the second protective shed 3, and the bottom end of the bottom strip 17 is higher than the top end of the first protective shed 2, and the top end of the top strip 14 is higher than the bottom end of the bottom strip 17. The top strip 14 is limited by the two bottom strips 17 to prevent the first protective shed 2 and the second protective shed 3 from separating when the first protective shed 2 or the second protective shed 3 is moved. The side of the outer strip 13 close to the first protective shed 2 is snap-fitted with the side of the inner strip 16 away from the second protective shed 3. The snap-fitting of the inner strip 16 and the outer strip 13 can strengthen the limitation of the first protective shed 2. Push the first support rod 9 at the bottom end of the first protective shed 2 to slide away from the second protective shed 3 on the first slide rail until the top strip 14 contacts the bottom strip 17 close to the first protective shed 2, and the outer strip 13 and the inner strip 16 are in contact. Then work can be carried out at the bottom ends of the first protective shed 2 and the second protective shed 3.

[0024] Working principle: During use, first, lay the ground rail 1 inside the tunnel after excavation by external force. Then, fix the connecting fixing plate 8 to the bottom end of the mounting plate 7 with bolts to fix the two ground rails 1. After fixation, place the first protective shed 2 on the top of the two ground rails 1 by external force, and fix the first protective shed 2 outside the first slide rail 4 by the first chute 10 at the bottom end of the first support rod 9. Then, place the second protective shed 3 on the top of the two ground rails 1 by external force, and the second protective shed 3 is located outside the first protective shed 2. The top clamping strip 14 is located between the two bottom clamping strips 17, and the outer clamping strip 13 is located on the side of the inner clamping strip 16 close to the second protective shed 3. And fix the second protective shed 3 outside the second slide rail 5 by the second chute 18 at the bottom end of the second support rod 15. Then, push the first support rod 9 at the bottom end of the first protective shed 2 to slide away from the second protective shed 3 on the first slide rail 4 until the top clamping strip 14 contacts the bottom clamping strip 17 close to the first protective shed 2, and the outer clamping strip 13 contacts the inner clamping strip 16. Then, work can be carried out at the bottom ends of the first protective shed 2 and the second protective shed 3. When it is necessary to extend into the tunnel, push the second support rod 15 at the bottom end of the second protective shed 3 to slide close to the first protective shed 2 on the second slide rail 4 until the bottom clamping strip 17 far from the first protective shed 2 contacts the top clamping strip 14. Then, push the first support rod 9 at the bottom end of the first protective shed 2 to slide away from the second protective shed 3 on the first slide rail 4 until the top clamping strip 14 contacts the bottom clamping strip 17 close to the first protective shed 2, and the outer clamping strip 13 contacts the inner clamping strip 16. At this time, work can continue. When the first protective shed 2 moves to the end of the ground rail 1 close to the inside of the tunnel, pull the pull ring 6 at the end of the ground rail 1 by external force to drive the ground rail 1 to move into the tunnel to the required position. Then, adjust the positions of the first protective shed 2 and the second protective shed 3.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
