The invention discloses a screening device and a using method for mixture reproduction for petroleum asphalt, and relates to the technical field of the petroleum asphalt. The screening device for mixture reproduction for the petroleum asphalt comprises a rack, wherein a reducing motor is arranged at the top of the left wall of the rack, and the output shaft of the reducing motor is fixedly connected with one end of a driving rod by a coupling, one end, away from the reducing motor, of the driving rod is movably connected with the top at the left side of the right wall of the rack, and an eccentric rotating wheel is sleeved on the driving rod, and the bottom of the eccentric rotating wheel is slidingly connected with the top of a contact plate. The screening device for mixture reproductionfor the petroleum asphalt solves the problems of poor shaking stability and poor service life of a vibration mechanism in the prior art by the cooperative setting of the reducing motor, the driving rod, the eccentric rotating wheel, an upper box mechanism and a lower box body, and by the cooperative setting of a horizontal shaking mechanism to drive a lower linkage mechanism to move back and forthrepeatedly.

The invention relates to the technical field of mechanical arms, and discloses an intelligent mechanical arm for manufacturing mechanical parts, comprising a base, a moving block is movably connected to the inside of the base, and a buffer spring connected to the base is fixedly connected to the front side of the moving block. The intelligent mechanical arm used for manufacturing mechanical parts can move when the mechanical failure of the mechanical arm body collides with the surrounding environment through the moving cavity and the movable groove. During this process, the mechanical arm body is forced to move backward during the impact. The body of the mechanical arm drives the mounting seat and the moving block to move backward, and the buffer spring is stretched under force to play a preliminary buffer role. When the moving block moves, the rotating plate contacts the inner wall of the moving groove and rotates under force, so that the torsion spring Force compression plays a further buffering role. This device uses a series of mechanical structures to make the body of the robot arm move under force when it fails and collides with the surrounding environment, reducing the damage to the body of the robot arm.

The invention relates to the technical field of bridge drainage equipment. Disclosed is a bridge deck drainage structure, comprising several branch pipes fixedly connected to the bridge and main pipes connected to the several branch pipes, the main pipe is located below the branch pipes; an annular groove is provided on the inner wall of the branch pipe, and a sliding block is slidably connected in the annular groove, and There is a first spring between the slider and the ring groove; it also includes a stabilizing mechanism symmetrically arranged along the center line of the slider. The stabilizing mechanism includes a block fixed on the bridge, an air bag between the branch pipe and the block, and The block moves vertically to inflate the air bag; both sides of the branch pipe are connected with side pipes that open and close with the vertical movement of the slider, and the end of the side pipe away from the slider is located below the air bag and communicates with the branch pipe; The spacing is greater than the spacing between the baffle plate and the branch pipe. This solution mainly solves the current problem that during strong stormy weather, the rainwater has a large impact on the branch pipe due to the large amount and fast flow rate, causing the branch pipe to shake, resulting in the problem that the connection between the branch pipe and the main pipe is easily broken or damaged.
