According to the through-flow turbine draft tube man access door opening-closingdevice provided by the invention, the manual operation can be reduced, the opening-closing difficulty of the draft tube man access door is greatly reduced, the safety in opening and closing the drafttube man access door is greatly improved, and the personal safety of an operator is ensured.

The invention discloses a large-tonnage hydraulic flat plate self-unloading machine. The large-tonnage hydraulic flat plate self-unloading machine structurally comprises a connecting hook, a lifting plate, fixing columns, a lifting device, a self-unloading bucket, a frame, a water outlet, wheels and a tail lamp, wherein the lifting plate is arranged at the front end of the frame and is of an integrated structure, and the two wheels are embedded in the two sides of the rear end of the frame. The flat plate self-unloading machine has the advantages that the interior of the lifting device drivesa main transmission mechanism to rotate through a transmission motor, then power is output in two directions through second transmission mechanisms, and hoisting plates in first transmission mechanisms on the two sides are driven to be lifted, so that a hoisting mechanism is pushed to lift the lifting plate, the connecting hook can be conveniently used for hooking, the manual operation strength isgreatly saved, time and labor are saved, and the situations that squatting happens and the machine runs over and injuries workers during vehicle hooking and backing-up can be avoided.

The invention provides a shot-blasting and sand-blasting cleaning device which comprises a cleaning chamber, a shot-sand circulating system and a workpiece conveying system. The cleaning chamber is internally provided with a plurality of impeller heads which are connected with the shot-sand circulating system. The workpiece conveying system penetrates through the cleaning chamber. The shot-blasting and sand-blasting cleaning device is characterized in that the shot-sand circulating system comprises a conveying mechanism located at the bottom of the cleaning chamber, a lifting mechanism connected with the conveying mechanism, a shot-sand separating mechanism connected with the lifting mechanism, an air injection mechanism connected with the shot-sand separating mechanism, and a heating mechanism connected with the air injection mechanism, and the impeller heads are connected with a shot outlet of the shot-sand separating mechanism. The shot-blasting and sand-blasting cleaning device provided by the invention is stable and reliable in operation, high in overall efficiency and low in energy consumption, and cleaning efficiency and the cleaning effect are improved; meanwhile, the surfaces of workpieces are kept dry, reoxidation and rusting are prevented, and the dust content of exhausted gas is reduced; and in addition, cleanliness of the work environment and the external surroundings is guaranteed.
