Description

Technical Field

[0001] This utility model relates to the field of rockfall simulation test technology, specifically a rockfall translational and rotational simulation test device. Background Technology

[0002] Rockfall barriers are one of the main measures to prevent landslides and rockfalls along mountainous highways and railways in my country. However, the impact of falling rocks on rockfall barriers is a complex dynamic process that is affected by many factors. Currently, the pendulum test device is widely used in indoor simulation of falling rocks impacting rockfall barriers. However, this method of simulation involves the falling rocks swinging but not rotating, resulting in a significant difference between the experiment and reality. Furthermore, the pendulum test relies on the weight of the falling rocks and gravity to complete the impact test, without acceleration, thus failing to simulate the real scenario of falling rocks impacting rockfall barriers.

With the connection of the electric cylinder and the baffle, the baffle and the receiving chamber are fitted together to regulate the gas pressure in the gas chamber. With the connection of the push rod and the push plate, the gas pressure causes the push rod to impact the convex ball, completing the control operation of the initial velocity of the convex ball.

[0029] Working principle: When the convex ball 8 impacts the soil cushion layer 31, gas is transported to the gas chamber 65 through the connecting pipe. The gas pressure is controlled by the gas pressure sensor. Under the action of the electric cylinder 62, the position of the baffle 614 in the receiving chamber 613 is controlled, so that the gas in the gas chamber 65 enters the regulating chamber 66, which in turn causes the push rod 610 to impact the convex ball 8, so that the convex ball 8 is launched from the launching tube 61. Under the action of the inclined plate 21, the convex ball 8 is continuously accelerated, so that the convex ball 8 impacts the soil cushion layer 31. Under the action of the pressure sensor between the soil cushion layer 31 and the retaining wall 3, the relevant data of the impact test are obtained, and the test is completed. Under the action of the baffle 7, the real state of the uneven slope can be simulated. Under the action of the inclined plate 21, the translation and rotation test operation of the convex ball 8 is completed.
