[0015] Compared with related technologies, the earthquake-proof protection frame for tunnel engineering provided by the present invention has the following beneficial effects:

[0016] 1. The provision of anti-slip pads can effectively increase the friction with the tunnel wall, prevent the base from sliding, and facilitate support for the tunnel. The provision of a shock-absorbing mechanism within the shock-isolating frame can significantly reduce the damage caused by vibration to the device, thereby improving the safety of tunnel construction. The shock-absorbing spring and the auxiliary shock-absorbing mechanism are used in combination to reduce the vibration pressure in the horizontal and vertical directions until it dissipates, which can significantly reduce the amplitude of the upper shock-isolating frame's descent and the frequency of vibration. The auxiliary shock-absorbing mechanism is used to reduce the pressure of the shock-isolating frame's vibration, thereby further enhancing the shock-proof effect.

[0017] 2. The width adjustment mechanism simultaneously drives the card plate and the connecting plate to adjust, thereby achieving rapid and precise width adjustment, so that it can adapt to the construction requirements of tunnels of different widths. The coordinated use of the telescopic rod and the second bevel gear achieves synchronization between the connecting plate and the card plate during width adjustment, ensuring the stability and balance of the device during the adjustment process. When the first bevel gear drives the telescopic rod to rotate, the telescopic rod rotates along the guide frame, thereby ensuring smooth rotation of the telescopic rod, which is conducive to the operation of the driving connection mechanism. At the same time, the introduction of the guide frame significantly enhances the stability and guidance of the telescopic rod during the telescopic process, reduces the adjustment error caused by bending or offset of the telescopic rod, and further improves the width adjustment accuracy of the device.

[0018] 3. When the connecting block is driven to slide along the connecting rod by the connecting rod, one end of the connecting rod synchronously drives the rectangular block to slide along the rectangular rod, thereby causing the two ends of the connecting rod to move synchronously, guiding the connecting rod. The connecting rod is guided by the rectangular block to ensure smooth movement of the connecting rod, which is beneficial to the operation of the shockproof mechanism. The anti-slip pad on the top of the top plate is set in an arc shape, which can make it more adaptable to the curvature of the tunnel top, thereby making the top plate close to the tunnel top, which is beneficial to the fixing operation of the device. The setting of the limiting piece can effectively limit the card plate to ensure that it will not separate from the top plate, and the limiting effect is good. Through the telescopic function of the hydraulic cylinder, the shockproof protection frame can adapt to the ground at different heights, increasing the diversity of its usage scenarios. At the same time, the self-locking universal wheel enables the shockproof protection frame to be easily moved in different directions, thereby improving its flexibility.

[0019] Compared with the existing technology, the earthquake-proof protection frame for tunnel engineering provided by this solution can effectively improve the earthquake-proof performance, reduce the tilt and instability caused by vibration, and thus ensure the safe progress of tunnel construction.

[0033] The embodiment of the present invention provides a seismic protection frame for tunnel engineering, such as Figure 1-10 As shown, the earthquake-proof protection frame for tunnel engineering includes: a base 1 and a top plate 2 arranged above the base 1; a group of connecting plates 3 respectively arranged on both sides of the base 1; a group of card plates 4 all slidably mounted on the top plate 2; a plurality of anti-slip pads 5 respectively assembled on a group of the connecting plates 3 and a group of card plates 4; a plurality of earthquake-proof frames 6 respectively installed on a group of the connecting plates 3 and the bottom of the base 1, and a plurality of the earthquake-proof frames 6 are slidably provided with support legs 7; earthquake-proof mechanisms respectively arranged on the plurality of earthquake-proof frames 6 for earthquake-proofing the connecting plates 3 and the base 1; a width adjustment mechanism arranged on the base 1 for adjusting the distance between a group of connecting plates 3 and the card plates 4; a height adjustment mechanism arranged on the base 1 for adjusting the height of the top plate 2.

[0034] In this embodiment, when in use, the device is first moved to a specified position, and then the height adjustment mechanism is simultaneously activated, so that the height adjustment mechanism drives the top plate 2 to slide upward, so that the top plate 2 drives the card plate 4 upward, and when the top plate 2 contacts the top of the tunnel, the height adjustment mechanism is closed, and then the width adjustment mechanism is activated, so that the width adjustment mechanism simultaneously drives a group of card plates 4 and a group of connecting plates 3 to slide, so that a group of card plates 4 and a group of connecting plates 3 slide away from each other, so that the anti-slip pads 5 on a group of card plates 4 and a group of connecting plates 3 slide and contact the tunnel surface, and then the connecting plates 3 and card plates 4 clamp the inner wall of the tunnel, so that the device is stable;
