Description

Technical Field

[0001] This project falls under the field of automated transportation of radioactive standard sources, specifically involving automated loading and unloading devices for aviation radioactive standard models. Background Technology

[0002] Airborne radiometric surveying is a major method in airborne geophysical exploration. Airborne geophysical exploration is a new type of mineral exploration technology, an advanced and efficient method for directly searching for metallic mineral deposits and predicting areas with potential for mineral exploration. With the continuous development of airborne geophysical exploration instruments, airborne geophysical technology has been widely applied in many fields.

[0003] Airborne radiometric measuring devices are installed on aircraft, and calibration tests must be completed before takeoff. This necessitates frequent transport of standard models used for radiometric measurements between storage warehouses and airports. To ensure the accuracy of the standard model data, the models must not be stacked, bumped, or damaged during handling and transportation, posing a significant challenge to practical operation. Previously, companies relied entirely on manual handling, which was not only inefficient but also posed a threat to the health of workers due to the radioactivity of the standard models themselves and prolonged close contact.

[0004] In summary, the frequent storage and transportation of standard models for radiometric measurements, coupled with stringent placement and securing methods, and the need to minimize human intervention due to the trace radioactivity of these models, all contribute to the difficulty and rigor of standard model storage and retrieval. Furthermore, the measurement of standard data by airborne radiometric measurement devices is a crucial aspect of radiometric measurement. Therefore, improving the efficiency of standard model loading, unloading, and transportation is currently the biggest challenge facing enterprises and a core issue in the development of airborne radiometric measurement. Consequently, designing a device capable of efficient and automated storage and retrieval of standard models is extremely important. Summary of the Invention

The device has the advantages of simple operation, high degree of automation, strong stability, and reasonable cost. It can meet the needs of quick storage, stable transportation, and convenient retrieval of standard models, standardize storage and retrieval, greatly improve the efficiency of airborne geophysical exploration equipment experiments, reduce the loss of standard models and radiation risks to personnel during transportation, and play a certain role in promoting the development of China's airborne geophysical exploration industry, and has broad market value.

[0025] Two storage racks 1 and one transport rack 2 are symmetrically arranged on the base plate 4. The two storage racks 1 are fixed to the left and right sides of the base plate 4 respectively. The transport rack 2 is located between the two storage racks 1. The transport rack 2 includes a liftable tray 3 for grabbing and storing the standard model 5.

[0026] Furthermore, the storage rack 1 is a lane stacking type, and each row of storage rack 1 consists of storage positions 22 evenly arranged in 4 rows × 4 columns. Each storage rack 1 can store 16 standard models 5. Each storage position 22 is equipped with a limiting baffle 14 adapted to the outline of the standard model. The bottom of the storage rack 1 is fixedly connected to the base plate 4. Two rows of slide rails 6 are installed at the top and bottom between the two rows of storage racks 1, which are connected to the transport rack base plate 8 and the transport rack top plate 13 to support and guide the longitudinal movement of the transport rack 2 when the gear 15 and rack 16 are engaged.

[0027] Further, the transport rack from bottom to top is successively a transport rack bottom plate 8, a lower transmission plate 9, a support plate 10, a lifting plate 11, an upper transmission plate 12, and a transport rack top plate 13. A first servo motor 18a is provided between the transport rack bottom plate 8 and the lower transmission plate 9. The first servo motor 18a drives a transmission shaft 23 to rotate through a first bevel gear set 17a. The rotation of the transmission shaft 23 drives the gear 15 and the rack 16 to engage and drive, realizing the longitudinal movement of the transport rack 2. The lower transmission plate 9 and the support plate 10 are in meshing transmission through a face gear 19. Through the face gear 19, the structure between the support plate 10 and the upper transmission plate 12 can rotate, and a support shaft 20 is provided to maintain balance. A second servo motor 18b is provided between the lifting plate 11 and the upper transmission plate 12 to drive a second bevel gear set 17b to drive a wire winding drum 21 to wind and unwind a steel wire rope, enabling the pallet 3 to move up and down. The transport rack top plate 13 and the upper transmission plate 12 are connected by a bearing 24.

[0028] Further, the pallet 3 is in a "mountain" shape and is located between the support plate 10 of the transport rack and the lifting plate 1. A lead screw 25 is provided on the side of the pallet 3. The lead screw 25 is driven by a third servo motor 18c to drive a magnet seat 26 to move back and forth along the pallet 3. An electromagnet 29 is provided on the magnet seat 26 for adsorbing the standard model 5. The adsorption surface of the electromagnet 29 covers a permanent magnetic material layer and is connected to a power-off self-locking circuit. A T-shaped cross-section angle steel 30 is welded to the bottom of the pallet 3, and lifting lugs 27 with through holes are provided on both sides. The steel wire rope passes through the lifting lugs 27 and is connected to the wire winding drum 21.

[0029] Working principle: First, the transport rack rotates. The transport rack needs to turn before entering, rotating the standard model 90° to facilitate directly pushing it into the storage position. The standard model is sent to the position where it needs to be stored through longitudinal lifting and horizontal movement, and final position adjustment is performed. The structure between the support plate and the upper transmission plate can rotate as a whole. The power for rotation comes from the servo motor at the bottom. Through the transmission of the face gear, the rotation of the transport rack is realized. Then, the pallet is lifted for temporarily placing the standard model during the access process. The pallet is in a "mountain" shape. The four corners of the pallet are connected to the optical axis sliding rods, and lifting lugs with holes are welded on both sides. The traction steel wire rope is placed between the lifting plate and the upper transmission plate. The servo motor on the upper transmission plate drives a pair of bevel gears to rotate the wire winding drum to realize the winding and unwinding of the steel wire rope, enabling the pallet to move up and down. Then, a servo motor is provided between the transport rack bottom plate and the lower transmission plate. The servo motor drives the transmission shaft to rotate through a pair of bevel gears. The rotation of the transmission shaft drives the gear to rotate. After the gear rotates and meshes with the rack, the standard model is pushed in. A servo motor is installed on the pallet to drive the magnet seat to move back and forth through the lead screw. When the pallet slightly descends until the plane of the pallet is flush with the plane of the storage position, the standard model is directly pushed into the storage position by the push of the magnet seat. The steps for taking out the standard model are the reverse of the above steps.
