[0002] Overpass bridges are bridges that cross over roads, railways or urban roads. They cross over existing lines. They are divided into separated and interchange types. The former only ensures that vehicles on the upper and lower lines can pass independently; the latter allows vehicles on the upper and lower lines to pass each other, and complex circuitous ramps are built on the plane and elevation, occupying a lot of land. In order to reduce noise, prestressed concrete bridges are often used.
[0003] When constructing an overpass, since the construction location is above the highway, falling objects may fall directly onto the highway during construction, affecting vehicles traveling underneath.

[0004] In the prior art, falling objects are blocked by supporting a length-adjustable protective plate at the bottom of the construction bridge. Although this method can block and protect falling objects, most of the falling objects during construction are small stones. When there are many small stones on the protective plate and more small stones fall, they may collide with the small stones on the protective plate and deviate to the outside of the protection range of the protective plate and fall onto the bottom road, affecting the movement of vehicles.

[0023] In the present invention, a corresponding propulsion assembly 2 is arranged in the protective plate group 1, so that the debris falling onto the protective plate group 1 can be pushed into the support plate 13 at any time, and guided to the bottom collection box 8 for centralized cleaning through the telescopic sleeve 7 on the support plate 13; the debris on the protective plate group 1 is cleaned by controlling the propulsion assembly 2 arranged on the protective plate group 1; and the debris on the protective plate group 1 is cleaned through the push plate 21 connected to its output end under the propulsion of the driving member 22, so as to prevent the small stones from falling when there are many small stones on the protective plate, colliding with the small stones on the protective plate, and possibly deviating to the outside of the protective range of the protective plate and falling to the bottom road to affect the travel of the vehicle.
[0024] The push plate 21 provided in the present invention includes a vertically arranged first fixed plate 211 and an inclined shovel plate 212. The vertically arranged first fixed plate 211 is fixedly connected to the driving end of the driving member 22. When driven by the driving member 22, the inclined shovel plate 212 can be used to shovel away debris under the support of the fixed plate, so that the cleaning can be more thorough. Under the push of the push plate 21, the debris on the protective plate group 1 will be pushed onto the support plate 13, and will be collected into the collection box 8 through the pouring trough 6 opened on the support plate 13 and the telescopic sleeve 7 for centralized treatment.

The motor 52 is rotated to rotate the threaded rod 54 arranged on the top thereof, so that the movable sleeve 55 is moved up or down with the assistance of the sliding rod 53, thereby adjusting the support plate 13 arranged on the top of the movable sleeve 55 to a suitable height.
[0031] The method of using the highway construction safety protection device of the utility model is as follows:
[0032] The device is moved as a whole to the bottom of the bridge body through the base 4, and the second sliding plate 12 is pulled according to the area of the construction area to be protected, so that it slides on the first sliding plate 11, thereby changing the area protected by the first sliding plate 11 and the second sliding plate 12. After the adjustment is completed, the set limit rod 92 is inserted into the limit hole opened by the first sliding plate 11 and the second sliding plate 12, and the limit member 91 is tightened to stabilize the relative distance between the adjusted first sliding plate 11 and the second sliding plate 12. At this time, the motor 52 is controlled to rotate so that the threaded rod 54 set on the top thereof is rotated, so that the set moving sleeve 55 is moved up with the assistance of the sliding rod 53, and the support plate 13 set on the top of the moving sleeve 55 is adjusted to a suitable height;
[0033] When there are too many debris on the first sliding plate 11 and the second sliding plate 12, the push plate 21 is pushed by the driving member 22, so that the shovel plate 212 pushes the fallen debris into the pouring trough 6 opened on the support plate 13, and collects the debris into the collection box 8 through the telescopic sleeve 7 for centralized processing;
[0034] In order to prevent the push plate 21 from pulling back the fallen debris when it is pulled back, a corresponding propulsion assembly 2 is provided for assistance. In a normal state, the shovel plate 212 is in close contact with the protective plate assembly 1. With the driving of the driving member 22, the shovel plate 212 will push the debris dropped from the first sliding plate 11 and the second sliding plate 12 forward. When the push plate 21 touches the first pressure sensor 31 provided in the first sliding plate 11, after the first pressure sensor 31 is pressurized, the first pressure sensor 31 will feed back a signal to the controller 33, so that the first cylinder 35 is controlled by the controller 33. At this time, the first cylinder 35 is controlled by the controller 33. The cylinder 35 will push the second fixed plate 34, thereby lifting the propulsion assembly 2 installed on the second fixed plate 34, and separating the push plate 21 from the protective plate group 1, and pulling the propulsion assembly 2 back through the driving member 22. At this time, the push plate 21 will not push the debris on the protective plate group 1 when it is separated from the protective plate group 1 and pulled back. When the push plate 21 is pulled back to a certain position and touches the second pressure sensor 32, the first cylinder 35 will pull the second fixed plate 34 back, re-adjust the propulsion assembly 2 to its original position, and re-fit the push plate 21 with the protective plate group 1.
