Description

Technical Field

[0001] The utility model relates to the technical field of nuclear technology utilization equipment, in particular to an inverted source device for recycling waste industrial cobalt 60 source rods. Background Art

[0002] Radioactive sources play an extremely important role in the nuclear technology application industry. The application scope of radioactive sources is getting wider and wider. As the use of radioactive sources expires, these radioactive sources need to be decommissioned. The decommissioning of radioactive sources is generally handed over to the production unit or stored in the city radioactive waste repository. For high-activity radioactive sources such as cobalt-60 radioactive sources for industrial irradiation, the activity of a single cobalt source is still about 720 / 860 Curies when it reaches the retirement age.

[0003] In the past, the only way to decommission cobalt sources was to store them at disposal sites. This method of disposal not only increases the storage pressure at disposal sites and increases disposal costs for users, but is also not conducive to resource conservation and environmental protection. The recycling and reuse of waste cobalt sources can extend the service life of cobalt sources, reduce the final disposal volume of waste radioactive sources, and reduce the storage pressure at disposal sites, thereby further achieving the goal of saving resources and protecting the environment.

[0004] However, the main problem that needs to be solved in the recycling and reuse of waste cobalt sources is the repackaging of the source rods and the inverted installation of the source rods. The inverted installation operation of the source rod refers to taking out the new source rod from the radioactive source transport shielding container or the source storage well waiting area and placing it on the source frame module, and then installing the source frame module on the source rack equipment; depending on the structural form of the source rack, the source rod is sometimes placed directly on the source rack equipment. During the service period, as the radioactive source decays, it is necessary to regularly add new source rods and adjust the positions of the existing source frame modules and source rods. When the radioactive source rod reaches the end of its life, the source rod is taken out of the source rack or source module and transported to the hot chamber for disassembly and final decommissioning. The above series of operations on the source rod is called the inverted source operation. Utility Model Content

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] 1. Compared with the existing threaded method, the interconnection method of various source loading tools in the waste industrial cobalt 60 recycling source rod inverted source device of the utility model can be quickly disassembled and assembled, which greatly shortens the time of disassembling and reassembling the source loading tools.

Compared with the original inversion source operation transportation method, which transfers the radioactive source and the source frame module from the storage well to the vicinity of the source rack and completely relies on the operator to carry the source rod assembly back and forth on foot, this section of transportation no longer requires personnel to carry the heavy source rod assembly at the wellhead of the source well by hand.

[0025] 3. The source rod fork and source rod clamp used in the waste industrial cobalt 60 recycling source rod inversion source device of the utility model can realize reliable picking up and changing the posture of large-mass source rods through the special design of the fork plate and the clamp.

[0043] The following is a clear and complete description of the technical solution of the utility model in combination with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model. The existing technology has the technical problem of cumbersome disassembly and assembly caused by the heavy weight of the new source and its adapted source frame module, and the inverted source operation requires frequent disassembly and assembly of different lengths of operating long rods with the source according to different operating depths. The existing long rod connection form is a threaded connection, and each disassembly and assembly takes a long time, which is a huge challenge to the operator's physical strength; secondly, the existing inverted source operation method transfers the radioactive source from the storage well to the vicinity of the source rack and completely relies on the operator to carry the heavy source rod assembly back and forth on foot, which will greatly increase the labor intensity and operation time of the personnel, resulting in reduced efficiency. Long-term operation near the storage well will also increase the risk of people falling into the water. Finally, there is the problem of source rod straightening: usually, the source rod is always in a vertical posture during the entire inverted process from the source rod being taken out of the shielding container to the source rack equipment. In actual source reversal operations, the source rod often detaches from the operating tool and falls to the bottom of the source storage well due to operating errors and other reasons, and becomes horizontal. Since the new source rod is obviously thicker and heavier than the old source rod, the original source rod clamp cannot firmly control a section of the source rod to restore it to a vertical state for subsequent operations, regardless of its structure or operating force.

[0044] The technical scheme of the utility model is: a flip source device for recycling waste industrial cobalt 60 source rods, including a quickly disassembled connection mechanism, a source frame module clamp, a source rod fork, a source rod shovel, a magnifying glass, a locking plate clamp, a source rod flower basket straight hook and a curved hook, a source rod clamp, a source loading and unloading workbench, a source loading slide rail, and a source frame shelf;

[0045] The fast disassembly connection mechanism includes an embedded tube component, a spring locking device, and an outer tube component; the connection mechanism can quickly connect and separate various operating tool heads and long rod tubes of different lengths and handle components through a spring-loaded lock plate buckle.

[0046] The Shengyuan frame module fixture includes an outer sleeve component, a guide assembly, and an escapement device; wherein the outer sleeve component can be assembled with a long rod pipe of corresponding length through a spring-loaded lock plate buckle and a positioning column. The guide assembly is located on both sides of the escapement device and is a thin-walled corrugated plate processing part. Relying on its shape, the Shengyuan frame module can be accurately positioned on the source rack or the source loading and unloading workbench. The escapement device is connected to the lower end of the outer sleeve component by rivets, and the screw inside it can rotate freely. After the Shengyuan frame module is accurately positioned, by rotating the screw, the hanger at the upper end of the module is firmly screwed together with the screw. At this time, the Shengyuan frame module is reliably picked up, transferred to the predetermined position and placed, and the screw is rotated in the opposite direction to separate the source frame module fixture from the Shengyuan frame module.

[0047] The source rod fork includes an outer sleeve component and a fork body assembly; the outer sleeve component can be assembled with a long rod pipe of corresponding length through a spring-loaded locking plate buckle and a positioning column. The fork body at the end can pick up independent source rods scattered at the bottom of the source storage well, and can also pick and place individual source rods on the source rack or the source loading and unloading workbench.

[0048] The source rod shovel includes an outer sleeve component and a shovel body assembly; the outer sleeve component can be assembled with a long rod pipe of corresponding length through a spring-loaded lock plate buckle and a positioning column. The shovel body is connected to the lower end of the outer sleeve component through rivets, and can scoop up one or several source rods scattered at the bottom of the source storage well and transfer them to a suitable area.

[0049] The magnifying glass comprises a tube clamp assembly and a lens assembly; the lens assembly can be fixed at a proper position in front of the long rod pipe through the tube clamp assembly, and the engraved code on the top of the source rod can be read while operating the source rod.

[0050] The locking plate clamp includes an outer sleeve component and a clamp body plate; the outer sleeve component can be assembled with a long rod pipe of corresponding length through a locking plate buckle with a spring and a positioning column. The clamp body plate is connected to the lower end of the outer sleeve component by rivets, and the protective locking plate of the source rack can be opened or closed by rotating the clamp body plate.

[0051] The straight hook and curved hook of the source rod flower basket include an outer sleeve component, a straight hook component, and a curved hook component; wherein the outer sleeve component can be assembled with a long rod pipe of corresponding length through a spring-loaded locking plate buckle and a positioning column. The straight hook or curved hook at the end is connected to the lower end of the outer sleeve component by rivets, and is used to operate the source rod storage and transportation flower basket or underwater rope.

[0052] The source rod clamp includes an extension tube, a screw sleeve, a clamp body, a clamp head, a push rod assembly, and a trigger component; wherein the clamp head and the front end of the clamp body are connected by screws, and different source rods can be matched with clamp heads of different shapes. The rear end of the clamp body and the long rod pipe, the long rod pipes, and the long rod pipe and the trigger are all connected to the required length by screw sleeves, and a push rod assembly of corresponding length is installed inside the extension tube.

[0053] The source loading and unloading workbench includes a source frame tray, upper and lower frames, a hanging frame, and a flower basket tray; when needed, they are installed on the hooks on the wall of the source well. The pre-loading of source rods from the storage and transportation flower basket to the source frame module can be completed on the source loading and unloading workbench. Since its operating distance is shorter than operating directly at the bottom of the source well and the visual conditions are better, and multiple source rod flower baskets can be processed in batches, the operation is more convenient and efficient.

[0054] The source loading slide rail includes a track component, a slide rail clamp, a guide wheel group, and a universal hook. When loading the source, the equipment is installed at the bottom of the source well cover. The universal hook can be pulled by a wire rope to transport the source frame module or the source rod storage and transportation basket back and forth between the source rod preparation and pre-loading area and the target source rack area. Compared with the previous pure manual on-foot transportation, the labor intensity of the operator can be greatly reduced.

[0055] The source frame shelf includes a groove plate component, a base, and a reinforcing rib plate. It is placed at the bottom of the source well for temporary or long-term storage of empty source frame modules or source rods with extremely low activity and no use value.

[0056] The further technical solution of the utility model is: the embedded tube component of the fast disassembled connection mechanism also includes a positioning column; the tube wall is processed with a locking plate limiting elongated hole and a locking plate operation elongated hole; the embedded tube also includes a locking plate inside that can swing slightly around the fixed axis in the middle under the action of a torsion spring. The outer tube component also includes an L-shaped positioning column sliding groove processed on the tube wall and another locking plate limiting elongated hole corresponding to the embedded tube component.

[0057] By installing the embedded tube component or the outer tube component on various tool heads, operating handles, and extension tubes, the source rod operating tools for various purposes can be cascaded. The cascade operation mode of the connection mechanism that can be quickly disassembled is: align the positioning column of the embedded tube with the L-shaped notch of the outer tube, insert the embedded tube along the notch, and rotate 90 degrees after it is in place. At this time, the locking plate can be stuck in the positioning long hole of the outer tube wall under the action of the spring force, so that the embedded tube and the outer tube are reliably connected as one, and the relative axial and radial position changes will no longer occur. When the two need to be separated from each other, just press the locking plate downward at the thick and long hole of the locking plate operation of the embedded tube, so that the other end of the locking plate exits the locking plate limiting slender hole of the outer tube wall, so that the positioning column of the embedded tube rotates 90 degrees in the opposite direction along the L-shaped notch of the outer tube, and the separation operation is completed by pulling out the embedded tube.

[0058] A further technical solution of the utility model is that the fork body assembly of the source rod fork also includes a fork plate with a special shape design. The slot width of the fork plate is smaller than the outer diameter of the source rod end plug head, slightly larger than the outer diameter of the end plug neck, the slot length is greater than 2 times the diameter of the end plug head, and the end of the fork plate is processed into an upper curling shape with a certain arc. The above design ensures that the fork plate is not easy to fall off during the transportation and placement of the source rod after picking up the source rod. It can also be used to change the posture of the source rod. It and the source rod clamp are backup equipment for each other.

[0059] A further technical solution of the utility model is that the clamping component of the source rod clamp also includes a pair of annular clamps, and special bosses are processed inside the clamps to constrain the source rod.

[0060] The source rod clamp is operated as follows: squeeze the trigger, the clamp head opens, release the trigger, and the clamp head closes. The closed clamp can wrap the end plug of the radioactive rod inside it, and leave a certain amount of gap, so that the source rod can move freely and cannot escape the control of the clamp, thereby achieving the purpose of operating the source rod. Furthermore, due to the special shape design of the clamp after closing, it has the dual characteristics of a clamp and a hook. The end plug of the radioactive source rod will not generate a torque in the direction of opening the closed clamp. This feature enables the source rod clamp to reliably operate a large-mass new source rod. The source rod clamp can be used to operate a single source rod on a source loading and unloading workbench or source rack. It can also be used to change the posture of the source rod at the bottom of the source well, changing the source rod from a horizontal or inclined state to a vertical state for subsequent operations. It is a backup device for the source rod fork.

[0061] A further technical solution of the utility model is that the source slide rail device also includes a C-shaped fixed tube, and the slide rail fixture component is installed on the C-shaped fixed tube through a bolt clamp, and its position can be changed within the length range of the C-shaped fixed tube. The source slide rail is fixed on the edge of the manhole cover by a pair of slide rail fixture components, and by adjusting the distance between the two slide rail fixtures, it can adapt to manhole covers of different sizes without having to manufacture multiple sets of source slide rails to match the manhole cover size.

[0062] The source slide rail equipment also includes a rocker assembly, which is mainly composed of a wheel frame, a rope pulley, a rocker handle and other components. Two rope grooves are processed on the rope pulley, and a traction wire rope is wound inside each rope groove. The winding directions of the wire ropes in the rope grooves are opposite to each other. The other ends of the two traction wire ropes finally converge at the universal hook located in the slide rail through the guide wheel group and are connected and fixed to it.

[0063] The operation mode of the source loading slide rail equipment is as follows: before the source pouring work begins, the slide rail is first installed at the lower part of the source storage manhole cover, with one end close to the source rod preparation pre-loading area and the other end close to the source rack area. After the pre-installed source frame module in the loading area is picked up with an appropriate long-handled tool, the annular handle of the long-handled tool is hung on the universal hook of the source loading slide rail, and then the crank handle of the crank assembly is turned. The source frame module will be transported to the side of the source rack together with the long-handled tool under the pull of the traction wire rope. At this time, the long-handled tool is removed from the universal hook to continue the subsequent operation and place the source frame module in the predetermined position of the source rack.

[0064] Example: Figure 1-3 As shown, this embodiment provides a complete set of inverted source device equipment and layout for recycling waste industrial cobalt 60 source rods. It includes an integral long-handled source loading tool 1 and a source rod clamp 2, which can be assembled into a suitable length according to needs and hung on the railing of the source well mouth. The source loading and unloading workbench 3 is suspended on a hook on the wall of the source well. Its underwater depth meets the requirements of shielding and protection and has better visual conditions than operating directly at the bottom of the source well. The source rod storage and transportation basket 4 and the source frame shelf 5 are located at the bottom of the source well, and can be changed according to the operating needs of the source rod or the source frame. The source loading slide rail 8 is installed below the source well cover.

[0065] like Figure 4 As shown in (a) to (i), the source loading tool 1 includes a fast disassembly connection mechanism 11, and the handle components include a source frame module clamp 12, a source rod fork 13, a source rod shovel 14, a magnifying glass 15, a locking plate clamp 16, a straight hook 17 and a curved hook 18 for picking up a source rod basket, and a ring handle 19. The above components can be quickly combined and separated by the fast disassembly connection mechanism 11 to connect various types of operating tool heads and long rod pipes of different lengths and handle components.

[0066] like Figure 5 As shown in (a) to (b), the quick-detachable connecting mechanism 11 comprises: the inner tube 111 also includes a positioning column 112; a locking plate limiting elongated hole 1110 and a locking plate operating elongated hole 116 are processed on the tube wall; the inner tube 111 also includes a locking plate 113, which can swing slightly around a fixed axis 115 in the middle under the action of a torsion spring 114; the outer sleeve 118 also includes an L-shaped positioning column sliding groove 119 processed on the tube wall and another locking plate limiting elongated hole 1110 corresponding to the inner tube component.

[0067] The working principle of the quick-disassembly connection mechanism 11 is as follows: align the positioning column 112 of the embedded tube 111 with the L-shaped notch 119 of the outer tube 118, insert the embedded tube 111 along the notch, and rotate 90 degrees after it is in place. At this time, the locking plate 113 can be stuck in the limiting elongated hole 1110 of the outer tube 118 wall under the action of the spring force, so that the embedded tube 111 and the outer tube 118 are reliably connected to form a whole, and the relative axial and radial position changes will no longer occur. When the two need to be separated from each other, just press the locking plate 113 downward at the locking plate operation thick elongated hole 116 of the embedded tube 111, so that the other end of the locking plate 113 withdraws from the limiting elongated hole 1110 of the outer tube 118 wall, and then rotate the positioning column 112 of the embedded tube 111 90 degrees in the opposite direction along the L-shaped notch 119 of the outer tube 118, and pull out the embedded tube 111 to complete the separation operation. The embedded tube component or the outer sleeve component that can be quickly disassembled and assembled can be respectively installed on various tool heads, operating handles, and extension tubes to realize serial connection and cascade connection to form source rod operating tools for various purposes.

[0068] like Figure 6 As shown, the Shengyuan frame module fixture 12 includes an outer sleeve component 118, a guide assembly 121, and an escapement device 122; the escapement device is connected to the lower end of the outer sleeve component by a rivet 123, and the screw 1221 inside it can rotate freely. The outer sleeve component 118 of the Shengyuan frame module fixture can be extended by a tube 1111 (such as an inner tube component 111) with an inner tube component 111. Figure 5 (a) to (b)) The assembly components are assembled into an operating tool of suitable length.

[0069] The working principle of the Shengyuan frame module fixture 12 is as follows: the guide assembly 121 is located on both sides of the escapement device 122 and is a thin-walled corrugated plate processed part. Figure 1 ) or on the loading and unloading source workbench 3 ( Figure 1 ) Accurately position Shengyuan frame module 7( Figure 1 ), after the source frame module 7 is accurately positioned, by rotating the screw 1221, the hanger on the upper end of the module is firmly screwed together with the screw 1221. At this time, the source frame module 7 is reliably picked up, transferred to the predetermined position and placed, and the screw 1221 is rotated in the opposite direction to make the source frame module fixture 12 separate from the source frame module 7.

[0070] like Figure 7 As shown in (a) to (c), the source rod fork 13 includes an outer sleeve component 118, a fork body assembly 131, and a fork plate 1311 with a special shape design; Figure 8 (a) to (c), the source rod shovel 14 includes an outer sleeve component 118 and a shovel body component 141; Fig. 9, the magnifying glass 15 comprises a tube clamp assembly 151 and a lens clamp plate 152. The lens assembly can scoop up one or several source rods scattered at the bottom of the source storage well and transfer them to a suitable area.

[0071] The working principle of the source rod fork 13 is as follows: the slot width of the fork plate 1311 is smaller than the outer diameter of the end plug head 61 of the source rod 6, and slightly larger than the outer diameter of the end plug neck 62. The slot length is greater than twice the diameter of the end plug head 61, and the end of the fork plate is processed into an upper curling shape with a certain arc. The above design ensures that the fork plate is not easy to fall off during the transportation and placement of the source rod after picking up the source rod. It can also be used to change the posture of the source rod. It and the source rod clamp 2 are spare equipment for each other. The source rod fork 13 can pick up independent source rods scattered at the bottom of the source storage well, and can also pick and place individual source rods on the source rack or the source loading and unloading workbench.

[0072] The function of the source rod shovel 14 is to scoop up one or several source rods scattered at the bottom of the source storage well and transfer them to a suitable area.

[0073] The use of the magnifying glass 15 is as follows: loosen the bolts on the tube clamp component 151 to preliminarily install the magnifying glass on the extension tube 1111 of the long-handled tool. Because the refractive index of the magnifying glass in water and in air is different, the focal distance in water is generally several times that in air. The final position of the magnifying glass installed on the extension tube 1111 should be adjusted according to the observation in water. The code of the source rod 6 is engraved on the top surface of the end plug 61. The distance between the source rod operating tool head and the magnifying glass is about 5 times the distance that can be clearly observed with the lens in the air. When the lens assembly is adjusted to the appropriate position on the long rod pipe, the engraved code on the top of the source rod can be read while operating the source rod. When the lens fails or is damaged due to irradiation discoloration and needs to be replaced, the bolts on the lens clamping plate 152 can be loosened to install a new lens.

[0074] As shown in the figure, the source rod clamp 2 comprises an extension tube 26, a screw sleeve 28, a screw tube 27, a clamp body 23, and a clamp head which also comprises a pair of annular clamps 21 and 22, wherein a special boss is processed inside the clamp to constrain the source rod. A push rod assembly 29 and a trigger component, wherein the clamp head and the front end of the clamp body are connected by screws, and different source rods can be matched with clamp heads of different shapes. The rear end of the clamp body and the long rod pipe, the long rod pipe, and the long rod pipe and the trigger are all connected to the required length by screw sleeves and screw tubes, and a push rod assembly 29 of corresponding length is installed inside the extension tube.

[0075] The operation mode of the source rod clamp is: hold the trigger 210, the clamps 21 and 22 of the clamp head open, release the trigger, and the clamps 21 and 22 close. The closed clamp can wrap the end plug 61 of the radiation rod 6 inside it, and leave a certain amount of gap, so that the source rod can move freely and cannot escape the control of the clamp, thereby achieving the purpose of operating the source rod. Further, due to the special shape design of the clamps 21 and 22 after closing, they have the dual characteristics of a clamp and a hook. The end plug of the radiation source rod will not generate a torque in the direction of opening the closed clamp, and this feature enables the source rod clamp to have the ability to reliably operate a large-mass new source rod. The source rod clamp can be used to operate a single source rod on the source loading and unloading workbench 3 or source rack 9. It can also be used to change the posture of the source rod at the bottom of the source well, changing the source rod from a horizontal or inclined state to a vertical state, so as to facilitate subsequent operations. The source rod clamp and the source rod fork are mutually backup equipment.

[0076] like Fig.11 As shown in (a) to (b), the source slide rail 8 includes a track component 82, a slide rail fixture 83, a guide wheel group 81, and a universal hook 86; a C-shaped fixed tube 822 is welded above the track component 821, and the slide rail fixture 83 is installed on the C-shaped fixed tube through a bolt clamp 831, and its position can be changed within the length range of the C-shaped fixed tube. The source slide rail is fixed on the edge of the manhole cover 90 by relying on a pair of slide rail fixture components. By adjusting the distance between the two slide rail fixtures, it can adapt to manhole covers of different sizes without having to manufacture multiple sets of source slide rails to match the manhole cover size. A rocking wheel assembly 85 is installed on the vertical pipe of the source fixture. The rocking wheel assembly is mainly composed of a wheel frame 851, a rope pulley 853, a crank handle 852 and other components. Two rope grooves are processed on the rope pulley, and a traction wire rope 854 is wound inside each rope groove. The winding directions of the wire ropes in the rope grooves are opposite to each other. The other ends of the two traction wire ropes finally converge at the universal hook 86 located in the track 821 of the track component through the guide wheel group 81 and are connected and fixed thereto.

[0077] The use of the source loading slide rail 8 equipment is as follows: before the source pouring work begins, the source loading slide rail is first installed at the lower part of the source storage manhole cover, with one end close to the source rod preparation pre-loading area and the other end close to the source rack area. After the source frame module 7 pre-installed in the loading area is picked up with an adapted long-handled tool 1, the annular handle of the long-handled tool is hung on the universal hook 86 of the source loading slide rail, and then the crank handle 852 of the crank assembly 85 is turned, and the source frame module 7 will be transported to the side of the source rack together with the long-handled tool 1 under the pull of the traction wire rope 854. At this time, the long-handled tool 1 is removed from the universal hook 86 to continue the subsequent operation, and the source frame module 7 is placed in the predetermined position of the source rack 9. In this way, the source frame module 7 or the source rod storage and transportation basket 4 is transported back and forth between the source rod preparation pre-loading area and the target source rack area, which can greatly reduce the labor intensity of the operator compared with the previous purely manual foot transportation.

[0078] like Fig.12 As shown in (a) to (c), the loading and unloading source workbench 3 includes an upper frame 31, a lower frame 32, a source frame tray 33, a hanging frame 34, and a flower basket support plate 35. The loading and unloading source workbench is equipped with multiple sets of source frame trays in the area close to the well wall, and the source frame module 7 can be placed in the slide slot of the source frame tray; the loading and unloading source workbench is equipped with multiple sets of flower basket support plates in the area close to the well wall, and the source rod storage and transportation flower basket 4 can be placed on the flower basket support plates;

[0079] The use of the source loading and unloading workbench 3 is as follows: when the source needs to be poured, first install it on the hook of the wall of the source well. The position of the hook should make the thickness of the water layer above the source loading and unloading workbench meet the shielding protection requirements. Use a long rod tool 1 to transfer the source frame module 7 and the source rod storage and transportation basket 4 that need to take / load the source rod 6 from the bottom of the source storage well or the source rack 9 to the appropriate area of ​​the source loading and unloading workbench, and use the source rod fork 13 or the source rod clamp 2 to complete the pre-loading of the source rod 6 from the storage and transportation basket 7 to the source frame module 7. Because its operating distance is shorter than operating directly at the bottom of the source well, the visual conditions are better, and multiple source rod baskets can be processed in batches, so the operation is more convenient and efficient.

[0080] like Fig.13 As shown in (a) to 16, the source frame shelf 5 includes a grooved plate component 51, a reinforcing rib plate 52, and a base 53. The source frame shelf is placed at the bottom of the source well for temporary or long-term storage of empty source frame modules or source rod source frame modules with extremely low activity and no use value. It can be used as a temporary storage place for the source frame module 7 during the source pouring period.

[0081] The use process and principle of the device of the utility model in a specific application scenario are as follows:

[0082] Initial preparation:

[0083] a. Remove unnecessary source storage well covers to expose the areas of the primary source storage well that need to be operated underwater, including the active rod preparation and pre-loading area and the source rack loading area; retain one or more covers for operators to use and move them to suitable locations.

[0084] b. Use a nylon soft rope to slowly place the source loading and unloading workbench 3 into the source well from above the source rod preparation and pre-loading area of ​​the source well and hang it at an appropriate height on the well wall.

[0085] c. Use a nylon soft rope to place the source frame shelf 5 into the source well. Its position is near the source loading and unloading workbench 3 and the area between the well cover.

[0086] d. Install the source loading slide rail 8 under the reserved manhole cover and fix it on the edge of the manhole cover with a slide rail fixture 83. One end of the installed track component 82 is above the side of the loading and unloading source workbench 3, and the other end is directly above the location of the source rack 9.

[0087] e. Assemble the long-handled operating tool 1. Different tools need to be assembled according to the different stages of the inversion operation:

[0088] The main tools used in the early and late stages are the straight hook 17 / bent hook 18 for operating the source rod storage and transportation basket 4; the lock plate pliers 16 for opening the top protective lock plate of the source frame 9. Depending on the operation object, the length of the long-handled pipe is assembled according to the actual operation depth. All tool heads, extension pipes 1111, and ring handles 19 can be quickly disassembled and assembled. The main tools used in the middle stage are the source rod fork 13, source rod shovel 14, magnifying glass 15, and source rod clamp 2 for operating the source rod 6 and the source frame module 7. The assembled long-handled operating tools can be hung on the edge of the source well when not in use.

[0089] Shengyuan frame module 7 ready for installation in empty warehouse:

[0090] a. Use a long-handled hook 18 to hook the lifting ring on the upper part of the new source rod storage and transportation basket 4 to transfer it from the storage position at the bottom of the source well to the basket storage area on the loading and unloading source workbench 3;

[0091] b. Use the lock plate pliers 16 to open the protective lock plate 91 at the top of the module channel of the source rack 9: Align the lock plate pliers and clamp them on the operating vertical plate of the protective lock plate 91, and turn it horizontally 90 degrees away from the center of the source rack, and the module channel will be opened. Repeat this operation to open all the protective lock plates on the module channel of the source rack.

[0093] 1) Align the two ends of the guide plate assembly 121 of the module fixture 12 to the grooves on both sides of the source rack module channel, and lower it along the groove. The screw 1221 of the fixture escapement device can automatically align with the thread of the middle suspension seat 921 of the channel cover.

[0094] 2) By rotating the screw 1221, the channel cover plate is engaged with the module fixture 12, and the channel cover plate is now reliably picked up.

[0095] 3) Then lift it out of the source rack module channel slide.

[0096] 4) Hang the long-handled tool carrying the channel cover plate on the universal hook 86 of the source slide rail 8 next to the source rack. By operating the crank handle 852 of the source slide rail, the channel cover plate is transferred to the source well source rod preparation pre-loading area under the traction of the wire rope 854. Remove the long-handled tool from the universal hook.

[0097] 5) Use a long-handled tool to continue placing the channel cover into the source frame tray slide slot of the source loading and unloading workbench 3 or the source frame shelf 5, and rotate the long-handled tool in the opposite direction to separate the channel cover from the source frame module fixture 12 and temporarily store it in the source frame tray.

[0098] 6) The empty source frame module fixture 12 is returned to the side of the source rack 9 again through the source loading slide rail 8.

[0099] 7) Repeat the above steps to remove the cover assembly in the next source rack module channel.

[0100] 8) After multiple cycles of operation, all the covers in the source rack module channel are removed, ready for subsequent source loading. d. Use the source rack module fixture to remove the empty source rack module:

[0101] 1) Align the two ends of the guide plate assembly 121 of the module clamp 12 to the grooves on both sides of the source frame module channel, and lower it along the grooves. The screw 1221 of the clamp escapement device 122 can automatically align with the thread of the upper end suspension seat 71 of the Tongsheng source frame module 7.

[0102] 2) By rotating the screw rod 1221, the source frame module 7 is engaged with the module fixture 12, and the source frame module 7 is now reliably picked up.

[0103] 3) Then lift it out of the source rack module channel slide. It should be noted that the lifting operation should be carried out under the monitoring of the dose meter.
