Description

Technical Field

[0001] The present invention relates to the field of shed tunnels, and particularly to a new type of energy dissipator applicable to energy dissipation shed tunnels. Background Art

[0002] A shed tunnel is a tunnel in the form of a shed, generally built in sections prone to falling rocks or debris flows, which can protect the safety of pedestrians and vehicles. The top of the shed tunnel is generally a cement board. Different from an energy dissipation shed tunnel, the top of an energy dissipation shed tunnel is built with a flexible protection material. When a falling rock hits the top of the shed tunnel, the flexible protection material can weaken part of the impact force received, thereby ensuring the service life of the top surface of the energy dissipation shed tunnel.

[0003] The existing energy dissipation shed tunnels can indeed play a role in weakening the impact force. However, as the service time increases, more and more falling rocks or other substances will accumulate on the top of the energy dissipation shed tunnel. The accumulated substances will tighten the flexible protection material until when falling rocks hit the top of the energy dissipation shed tunnel later, the flexible protection material cannot effectively weaken the impact force, and there is a risk of penetration and rupture on the top of the energy dissipation shed tunnel.

[0029] An energy dissipation unit that buffers the impact force of falling rocks received by the shed roof 10, and the energy dissipation unit is arranged above the shed roof 10.

[0035] An anti-rebound component is also provided between the receiving plate 4 and the roof plate 10 of the shed hole. The anti-rebound component is used to prevent a number of tension springs 12 from being stretched and quickly reset, causing the falling rocks to be bounced away by the receiving plate 4. The anti-rebound component includes a protective sleeve frame 14 fixed to the bottom of the roof plate 10 of the shed hole, and a first mounting seat block 18 is distributed inside the protective sleeve frame 14, and the first mounting seat block 18 is fixedly suspended at the bottom of the roof plate 10 of the shed hole.

[0036] The second limiting sleeve 15 and the second sliding column 16 are both located inside the protective sleeve frame 14 , and the receiving plate 4 protects the former.

[0037] Example 2: Please refer to Figure 7 and Figure 8 The present embodiment is a further explanation of the above embodiment. In the figure, a second mounting block 23 is further provided inside the protective sleeve frame 14, and the second mounting block 23 is also fixedly hoisted on the lower end surface of the shed hole top plate 10. A second rotating shaft 24 is rotatably provided inside the second mounting block 23, and a second movable ratchet 25 is fixedly sleeved on the outer surface of the second rotating shaft 24. The second movable ratchet 25 is relatively distributed with the first movable ratchet 20. A rotating disk 27 is also fixedly sleeved on the outer surface of the second rotating shaft 24, and a plurality of circular arc surfaces of the rotating disk 27 are provided. There are digital slots 28 evenly distributed around the circumference, and digital symbols are marked in order inside several digital slots 28. An observation slot 17 is opened at the bottom of the protective sleeve frame 14, and the observation slot 17 is located directly below the turntable 27. A second ratchet block 26 is fixedly provided on the outer surface of the second slide post 16, and the second ratchet block 26 is movably engaged with the second movable ratchet 25. When the second slide post 16 moves downward, the second movable ratchet 25 can be moved, and when the second slide post 16 is reset upward, the second ratchet block 26 cannot move with the second movable ratchet 25.

[0038] The outer wall of the turntable 27 is in sliding fit with the inner wall of the protective sleeve frame 14, and the rotation of the turntable 27 is affected by the frictional force generated by contacting the protective sleeve frame 14.

[0039] Working principle: When mountain rocks fall on the top of the shed tunnel, the flexible cushion block 5 can buffer the falling rocks. The buffered pressure is applied to the bearing plate 4, causing multiple first sliding columns 9 to sink under the influence of the force. During the sinking process, several tension springs 12 can also buffer the impact force a second time, that is, reduce the impact force directly received by the shed tunnel roof 10, thereby extending the service life of the shed tunnel roof 10.

[0040] When the first sliding column 9 moves downward and stretches the tension spring 12, the second sliding column 16 also moves downward. When the second sliding column 16 is reset under the action of the tension spring 12, through the engagement of the first ratchet block 22 and the first movable ratchet wheel 20, it will drive the first movable ratchet wheel 20 and the first rotating shaft 19 to rotate. Due to the action of the rotary damper 21, the first rotating shaft 19 will receive a resistance during the rotation, that is, it can extend the upward reset speed of the second sliding column 16, thereby avoiding the elastic force generated by the stretched tension spring 12 from bouncing the falling rocks away through the bearing plate 4 when instantaneously resetting, preventing the falling rocks from bouncing away randomly, and improving the stability of the stable downward discharge of the falling rocks.

[0041] Moreover, each time the second sliding column 16 moves downward, it can turn the second movable ratchet wheel 25 by a small angle through the second ratchet block 26. This small angle can switch the positions of two adjacent digit slots 28. The staff inside the shed tunnel can see the numbers on the digit slots 28 through the observation slot 17, that is, they can know how many times the shed tunnel roof 10 has been impacted by falling rocks during this period, which is convenient for recording the data of falling rocks on the mountain.

[0042] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to this process, method, article or device.

[0043] 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 principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
