Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 to 5 shown, the present utility model provides a safety protection device for foundation pits in highway engineering, including a bottom block 1, a bracket 2, and the bracket 2 is fixedly arranged above the bottom block 1;

[0023] An installation mechanism is fixedly installed on the side of the bracket 2. The installation mechanism includes a fixed outer shell 5 fixedly arranged on the side of the bracket 2. A groove 6 is opened inside the fixed outer shell 5. A spring 7 is fixedly installed at the bottom of the groove 6. A top plate 8 is fixedly installed at the top of the spring 7. A fixed plate 9 is movably installed above the top plate 8. A connecting rod 19 is fixedly installed above the fixed plate 9. A railing 10 is movably sleeved above the connecting rod 19. A handle 11 is fixedly installed at the top of the connecting rod 19.

[0024] When in use by the staff, the staff first inserts the fixing plate 9 into the interior of the fixing housing 5 through the groove 6. When the fixing plate 9 moves downward, it causes the top plate 8 to move downward. When the top plate 8 moves downward, the spring 7 is compressed. When the bottom of the fixing plate 9 contacts the fixing housing 5, then rotate the handle 11 by 90 degrees. When the handle 11 is rotated by 90 degrees, it drives the connecting rod 19 to rotate by 90 degrees. When the connecting rod 19 rotates by 90 degrees, it drives the fixing plate 9 to rotate by 90 degrees. At this time, the spring 7 generates an upward force on the top plate 8, and the top plate 8 generates an upward pushing force on the fixing plate 9.

[0025] By placing the fixing plate 9 into the interior of the groove 6 and rotating the handle 11, the fixing plate 9 is rotated. Then, through the cooperation between the spring 7 and the top plate 8, the fixing plate 9 is fixed, thereby fixing the railing 10. Compared with the traditional device, this device fixes the fixing plate 9 through the cooperation between the spring 7 and the top plate 8, thereby reducing the time for installing the railing 10 and improving the efficiency of installing the railing 10, thus improving the working efficiency of the device.

[0026] Among them, a fixing mechanism is fixedly installed on the side of the bracket 2. The fixing mechanism includes a fixing block 12 fixedly arranged on the side of the bracket 2. A round cover 13 is fixedly installed on the side of the fixing block 12. A knob 14 is rotatably installed between the round cover 13 and the fixing block 12. A threaded rod 15 is rotatably installed on the side of the round cover 13. The threaded rod 15 passes through both sides of the round cover 13, the knob 14, and the fixing block 12 in sequence. A limiting plate 16 is fixedly installed at one end of the threaded rod 15. A limiting rod 17 is fixedly installed on one side of the fixing block 12. The limiting plate 16 is movably sleeved with the limiting rod 17. A fixing rod 18 is fixedly installed on the side of another bracket 2. The fixing rod 18 is movably connected to the threaded rod 15.

[0027] When the staff needs to use it, the staff first retracts the telescopic rod 3 through the retracting mechanism. When the two brackets 2 approach each other, the fixing rod 18 will move to the side of the fixing block 12. When the hole on the side of the fixing rod 18 aligns with the threaded rod 15, then rotate the knob 14. When the knob 14 is rotated, since the connection between the knob 14 and the threaded rod 15 is provided with the same thread as the threaded rod 15, and the rotation of the threaded rod 15 is restricted by the limiting rod 17, so as the knob 14 rotates, it drives the threaded rod 15 to move forward. When the threaded rod 15 moves forward, it drives one end of the threaded rod 15 to gradually pass through the interior of the fixing block 12 and the fixing rod 18 in sequence. When one end of the threaded rod 15 completely passes through the interior of the fixing rod 18, then stop rotating the threaded rod 15.

[0028] By turning the knob 14, the threaded rod 15 moves forward. When the threaded rod 15 moves, it drives the limit plate 16 to move forward above the limit rod 17, so as to enter the inside of the fixed rod 18 through the threaded rod 15 to fix the position of the fixed rod 18. Compared with the traditional device, this device can quickly fix the fixed rod 18 through the cooperation between the knob 14 and the threaded rod 15, thus avoiding the loosening of the contraction rod 4 after contraction.

[0029] Among them, there are four groups of installation mechanisms, which are evenly and fixedly arranged on one side of the four brackets 2.

[0030] Through the four groups of installation mechanisms, the two ends of the two railings 10 can be respectively fixed above the four brackets 2.

[0031] Among them, the cross-sectional shape of the bottom block 1 is trapezoidal, and the cross-sectional area of the bracket 2 is the same as the top area of the bottom block 1.

[0032] Through the characteristic that the bottom area of the trapezoid is larger than the top area, the stability of the device can be improved.

[0033] Among them, a contraction mechanism is fixedly installed on the side of the bracket 2. The contraction mechanism includes a telescopic rod 3 fixedly arranged on one side of the bracket 2, and a contraction rod 4 is hingedly installed on the side of the bracket 2. The contraction rod 4 is located between the two telescopic rods 3.

[0034] Through the contraction mechanism, the two brackets 2 can be accommodated to save space.

[0035] Among them, there are two groups of contraction mechanisms, which are evenly distributed at both ends of the railing 10.

[0036] It can accommodate the structure composed of the two brackets 2 in the device and save storage space.

[0037] The working principle and usage process of the present utility model:

[0038] When the staff uses it, the staff first inserts the fixing plate 9 into the inside of the fixed housing 5 through the groove 6. When the fixing plate 9 moves downward, it will cause the top plate 8 to move downward. When the top plate 8 moves downward, the spring 7 will be compressed. When the bottom of the fixing plate 9 contacts the fixed housing 5, at this time, the handle 11 is rotated 90 degrees. When the handle 11 is rotated 90 degrees, it will drive the connecting rod 19 to rotate 90 degrees. When the connecting rod . When the connecting rod 19 rotates 90 degrees, it will drive the fixing plate 9 to rotate 90 degrees. At this time, the spring 7 will generate an upward force on the top plate 8, and the top plate 8 will generate an upward pushing force on the fixing plate 9.

[0039] When the staff needs to use it, the staff first contracts the telescopic rod 3 through the contraction mechanism. When the two brackets 2 approach each other, the fixed rod 18 will move to the side of the fixed block 12. When the hole on the side of the fixed rod 18 aligns with the threaded rod 15, then rotate the knob 14. When the knob 14 is rotated, since the connection between the knob 14 and the threaded rod 15 is provided with the same thread as the threaded rod 15, and the rotation of the threaded rod 15 is restricted by the limiting rod 17, so as the knob 14 rotates, it will drive the threaded rod 15 to move forward. When the threaded rod 15 moves forward, it will drive one end of the threaded rod 15 to gradually pass through the inside of the fixed block 12 and the fixed rod 18 in sequence. When one end of the threaded rod 15 completely passes through the inside of the fixed rod 18, then the rotation of the threaded rod 15 can be stopped.
