The invention relates to a liquid-state aluminum alloy electromagnetic conveying device which is composed of a molten aluminum heat-maintaining furnace part and a molten aluminum conveying part. The molten aluminum heat-maintaining furnace part comprises a heat-maintaining furnace and a heat-maintaining furnace cover, and a furnace side opening is formed in one side of the heat-maintaining furnace; the molten aluminum conveying part comprises a flat pump groove connected with the furnace side opening, a conveying pipe connected with the flat pump groove, an electromagnetic pushing device arranged at the section, where the flat pump groove is formed, of the conveying pipe and an air cooling system; the electromagnetic pushing device comprises two electromagnetic pump bodies, traveling wave magnetic fields are generated by magnet yokes, iron cores and coils, the magnet yokes, the iron cores and the coils are arranged in the electromagnetic pump bodies, and the traveling wave magnetic fields are interacted with induced currents excited by the traveling wave magnetic fields in molten aluminum in the flat pump groove to generate electromagnetic pushing force to push the molten aluminum in the flat pump groove to flow; a magnetic gap between the two electromagnetic pump bodies can be adjusted. By means of the liquid-state aluminum alloy electromagnetic conveying device, the heat-maintaining furnace is sealed by the heat-maintaining furnace cover, and molten aluminum alloy is conveyed through the sealed conveying pipe; meanwhile, the molten aluminum alloy is processed by the electromagnetic fields in the conveying process, and the automation level, the production efficiency and the casting quality are improved.

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. The slurry shield full-automatic pipe replacement crane is simple in structure and high in practicability, is successfully put into use, reduces the labor intensity of workers in the slurry pipe replacement process, and greatly improves the working efficiency.

A fish feeding boat, belonging to the field of fishery, is composed of a first motor, a mixing tank, a hull, a propeller, a solar panel, a storage battery, an air pump, a controller, a feeding control device, a second motor, a feed projection device and a first Composed of three motors, the mixing tank in this invention can hold a variety of feeds or medicines, and the stirring shaft can realize the uniform mixing of feeds and medicines, which greatly reduces the labor intensity of workers; the electromagnet and spring in this invention can realize The left and right movement of the blanking control plate realizes the lowering and stopping of the feed. The rolling body can reduce the friction of the blanking control plate when it moves; the first cylinder moves to compress the feed, and the compressed feed is located in the compressed block hole, and then With the movement of the second cylinder, the compressed feed can be projected far away by means of the movement of the second piston rod, and the compressed feed can expand the projection area, thereby realizing multi-area feeding.
