The invention relates to an improvement of a guard rail device in the railway rail equipment, which is particularly suitable for an erection of dangerous segments in a rail traffic. The structure of the guard rail device consists of guard rails and a positioning device which is used for fixing the guard rail on a timber so as to lead the guard rail to keep an even distance from a lateral side of a main rail. The key improvement lies in that the guard rail is positioned on a bracket with two turnover wing plates by a rail clamp and a locating bolt; with the assistance of groove-shaped holes and rotating axle of the groove-shaped holes on a groove edge of a groove-shaped base arranged on the two turnover wing plates, the bracket and a bracket base positioned on the timber with groove edges can form a hinge coordination, the position of which can be adjusted. The bracket and the bracket base can be combined with a corollary pressure plate as a whole by a fixed bolt pin and two fixed bolts to be fixed on the corresponding timber.

Disclosed is a slurry shield full-automatic pipe replacement crane. The slurry shield full-automatic pipe replacement crane comprises a trailer and a pipe replacement crane mechanism. The pipe replacement crane mechanism is installed on the trailer, and a pipe storage mechanism is arranged on the trailer. The pipe replacement crane mechanism comprises a pipe replacement crane longitudinal beam, wherein the pipe replacement crane longitudinal beam is connected with the trailer. A longitudinal translation oil cylinder is arranged on the pipe replacement crane longitudinal beam, and a travelling frame is connected to the stretching and drawing end of the longitudinal translation oil cylinder. A crane transverse beam frame and a transverse translation oil cylinder are arranged on the travelling frame, one end of the transverse translation oil cylinder is connected with the crane transverse beam frame, and the other end of the transverse translation oil cylinder is connected with the travelling frame. An electric hoist is arranged on the crane transverse beam frame, and moves along the crane transverse beam frame. A tank chain groove is formed in the top of the travelling frame, a tank chain groove is also installed in the lower surface of a platform on the top of the trailer, and the two tank chain grooves are connected through a tank chain.
