The invention discloses an unloading rack for logistics transportation. The unloading rack comprises a base plate. Side plates are welded to the top end of the base plate. The two side plates are eachinternally provided with multiple ascending-and-descending screw rods. Every two ascending-and-descending screw rods form a group, and the ascending-and-descending screw rods of each group are located at corresponding positions inside the two side plates correspondingly. Movable seats are symmetrically arranged on the ascending-and-descending screw rods of each group in a sleeving manner correspondingly. A goods shelf is welded between every two movable seats. A compression bolt is mounted on the outer wall of one side of each goods shelf. The unloading rack is provided with the ascending-and-descending screw rods, the movable seats and the goods shelves; when one goods shelf ascends and descends, firstly, a corresponding adjustment hand wheel is selected according to the corresponding goods shelf, and then, the corresponding adjustment hand wheel is pressed so that a driving engagement wheel can be engaged with a driven engagement wheel; at the moment, a limiting block is separated from the corresponding driven engagement wheel; and then, the corresponding adjustment hand wheel is rotated, and the corresponding ascending-and-descending screw rods inside side plates are driven torotate through rotation of rotating shafts and engagement of the engagement wheels.

The invention provides a clamping device, and belongs to the technical field of fish clamping for vessels. The clamping device comprises a base, wherein a supporting plate is arranged on the base; a rotating plate is arranged on the supporting plate; the rotating plate is further provided with a clamping mechanism and a rotating mechanism which are connected; and when the rotating plate rotates, the rotating mechanism fixed on the rotating plate is driven to act, and the clamping mechanism connected with the rotating mechanism is driven to act. According to the clamping device, the rotating mechanism acts on the clamping mechanism to clamp and fix fishes, and labor is facilitated and saved. The clamping device is suitable for operation on vessels, has simple clamping and releasing modes, and is convenient to unload, so that labor operation is facilitated, and work efficiency is greatly improved.

The invention discloses a through-flow turbine draft tube man access door opening-closing device, which comprises a lifting device, a steel wire rope, a guiding pulley and a man access door cover operation plate arranged on a turbine draft tube man access door. The guiding pulley is fixed onto an outer wall of the lower part of a draft tube through a pin shaft and a support plate, and is located on the opposite side of a hinge of a man access door cover; an installation position of the guiding pulley is higher than a position of the man access door cover operation plate; the lifting device isfixed onto a draft tube man access gallery wall and is located under the guiding pulley; one end of the steel wire rope is connected with the lifting device; the other end of the steel wire rope bypasses the guiding pulley and is detachably connected with the man access door cover operation plate through a safe connecting assembly; and when the turbine draft tube man access door is closed, the turbine draft tube man access door is connected with the draft tube through a man access door cover bolt-connection bolt. 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.
