The utility model discloses a bag cage convenient for quick mounting and dismounting of filter bags, and relates to the technical field of bag cages, the bag cage comprises a top ring and a transfer box, the transfer box is located right below the top ring, a plurality of first extension pipes are fixed on the peripheral side surface of the transfer box in a penetrating manner, and the plurality of first extension pipes are distributed in a circular array manner; two symmetrically-arranged limiting rods are fixed to the inner wall of the first extending pipe, and a first piston is slidably arranged in the first extending pipe. The water supply assembly is used for supplying water to the interior of the first extension pipe, so that the water pressure in the first extension pipe is increased, a first piston in the first extension pipe can be pushed to slide outwards by virtue of the water pressure, and a fixed block extends towards the exterior of the first extension pipe, so that a plurality of supporting rods are driven to expand outwards, and the plurality of supporting rods can support and tension the filter bag; after the water supply assembly draws away water in the first extension pipe, the multiple supporting rods can be folded towards the center, and therefore the filter bag can be conveniently and safely assembled and disassembled on the bag cage in a labor-saving mode.

The invention discloses a multi-station overturning and shifting workbench and a feeding and discharging method, and belongs to the technical field of shifting machines. The multi-station overturning and shifting workbench comprises an overturning base, a C-shaped overturning mechanism is rotationally arranged on the overturning base, and a forward clamping mechanism and a reverse clamping mechanism are arranged on the two sides of the overturning mechanism correspondingly; the forward clamping mechanism and the reverse clamping mechanism are arranged in the opening of the turnover mechanism, the forward clamping mechanism and the reverse clamping mechanism are both in sliding connection with the side wall of the opening of the turnover mechanism, the turnover mechanism is provided with a locking pin used for locking the positions of the forward clamping mechanism and the reverse clamping mechanism, and the forward clamping mechanism and the reverse clamping mechanism are oppositely arranged in the opening of the turnover mechanism so as to be used for clamping and fixing a workpiece. The turnover mechanism is used for controlling the feeding and discharging positions of the workpieces; a feeding and discharging platform is arranged on each of the two sides of the turnover mechanism and used for pushing the forward clamping mechanism and the reverse clamping mechanism to be connected with or separated from the turnover mechanism, double-side feeding and discharging of workpieces are achieved, and the space adaptability to super-long and super-wide special-shaped workpieces is greatly improved.

The present application belongs to the technical field of radioactive source transport equipment, and discloses a radioactive source transport container, which comprises a shielding container body, a fireproof cover assembly, a carrying base and a drawer assembly. A lead shielding layer is cast in the shielding container body, and two drawer channels are arranged for the drawer assembly to slide through. The shielding container body is connected with an end cover assembly for sealing the drawer channel ports and axially locking the drawer assembly. The fireproof cover assembly is arranged outside the shielding container body and comprises a fireproof cover outer cylinder and a fireproof cover inner cylinder. Heat insulation material is arranged between the inner and outer cylinders, and a damping structure is arranged at the top. The present application doubles the loading capacity of radioactive sources through the double-drawer channels, improves the transport efficiency, and enhances the ability of the container to resist drop and fire-burning composite accidents through double-layer heat insulation and integrated damping structure. The horizontal pull-out type loading and unloading method is safe and convenient to operate. The container of the present application is suitable for B(U) type package transport of special form radioactive sources such as cobalt-60 and cesium-137.

The utility model provides a boarding device. The boarding device comprises a boarding frame, a boarding plate, a driving assembly and at least two tongue plates. The boarding plate is hinged to the boarding frame around the first pivot; all the tongue plates are hinged to the boarding plate around the second pivot, and all the tongue plates are located on the side, away from the first pivot, of the boarding plate in the radial direction of the first pivot; the driving assembly comprises a first driving part and at least two second driving parts, the first driving part is connected with the boarding frame, the output end of the first driving part is connected with the boarding plate, the number of the second driving parts is equal to that of the tongue plates, the second driving parts are connected with the boarding frame, and the output ends of the second driving parts are connected with the tongue plates in a one-to-one correspondence mode; wherein the first driving piece is configured to drive the boarding plate to rotate around the first pivot so as to raise or lower the height of the boarding plate, and the second driving piece is configured to drive the tongue plate connected with the second driving piece to rotate around the second pivot so as to unfold the tongue plate. According to the boarding device, the adaptability to carriages with different widths can be improved.

The invention discloses an unmanned aerial vehicle cargo rapid loading and unloading device, and belongs to the field of logistics automation equipment. Comprising a workbench, a goods clamping assembly, an unmanned aerial vehicle parking frame and a control unit are arranged at the top of the workbench, a goods pushing assembly is arranged on one side of the workbench, and a flow guide plate is arranged on the other side of the workbench; the control unit is in signal connection with the goods clamping assembly, the goods pushing assembly and the unmanned aerial vehicle parking frame, and automatic control linkage of the three is achieved. According to the rapid cargo loading and unloading device of the unmanned aerial vehicle, through the core design of automatic closed-loop control, synchronous clamping transmission, the self-adaptive tray, the double groups of cargo pushing mechanisms and the like, efficient, safe and reliable cargo loading and unloading of the unmanned aerial vehicle are achieved. After receiving the in-place signal of the unmanned aerial vehicle, the control unit drives clamping, pushing, resetting and other actions according to a preset time sequence, manual intervention is not needed, the loading and unloading efficiency is greatly improved, and personal errors are reduced. The two clamping parts and the goods pushing assembly can work synchronously, two sets of goods can be loaded and unloaded at the same time, and the device is suitable for high-frequency logistics scenes.
