Description

Technical Field

[0001] The invention relates to the technical field of disassembly and assembly of waste filter cartridges, and in particular to a portable operating tool for a waste filter cartridge shielding transport container and a use method thereof. Background Art

[0002] The water filter is the core key equipment to ensure the water quality requirements in the primary circuit of a nuclear power plant, and is also an important consumable required for the daily operation of a nuclear power plant. Since the water filter element will intercept a large amount of radioactive particles in the primary circuit water system, such as waste resin, activated carbon, selective adsorption medium fragments and other insoluble radioactive particles, the waste filter element needs to be replaced in time when the filtering effect fails. According to the operating environment conditions of the Guohe series reactor nuclear power plants, the radioactivity level of the waste filter element 6 is relatively high, and the radiation risk to personnel during the replacement operation is relatively high. Therefore, a set of special shielded transport containers and supporting replacement tools are developed to achieve the replacement and transportation of the waste filter element 6 of the nuclear island plant under the principle of satisfying the radiation exposure of personnel as low as reasonably practicable (ALARA), so as to achieve the purpose of convenient replacement and radiation safety of personnel.

[0003] At present, when the waste filter element 6 is extracted, because the waste filter element 6 is arranged inside the shielding barrel 4, and the shielding barrel 4 is a confined space, the impurities left by filtering on the waste filter element 6 cannot be probed into to see, so that the inside of the shielding barrel 4 cannot be observed, and the position of the straight handle 61 inside the waste filter element 6 cannot be accurately obtained. At the same time, the relative position between the shielding barrel 4 and the waste filter element 6 is also unknown. Therefore, in the case of inaccurate positioning, it may cause the previous gripper to fail to grasp or grasp it off-center, resulting in problems such as grasping overload / filter element jamming. At this time, manual intervention is required, which will increase the radiation dose of personnel and increase the difficulty of handling the waste filter element 6. Therefore, it is very necessary to reduce manual participation in operations, and to use tools that can both ensure the success rate of grasping and reduce the radiation dose of personnel. Summary of the invention

[0004] The object of the present invention is to provide a portable operating tool for a waste filter element shielding transport container and a method of using the same, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, one of the purposes of the present invention is to provide a portable operating tool for a waste filter element shielded transport container, including a rope winch, a lifting device is provided at one end of the rope winch, and a grab hook is provided on the lower side of the lifting device. The rope winch is used to drive the grab hook and part of the lifting device to move up and down, so that the grab hook and the rope winch enter the interior of the shielding barrel, and the grab hook is hooked with the straight handle provided inside the shielding barrel. At the same time, a rotating drive component is provided on one side of the lifting device, and the rotating drive component drives the lifting device to rotate when rotating. During the rotation of the lifting device, the grab hook rotates with the lifting device. At the same time, during the descent of the grab hook, the grab hook adjusts its position according to the position of the straight handle, and is driven by the rotating drive component to hook and lock the grab hook and the straight handle. After the grab hook and the straight handle are hooked and locked, the grab hook pulls the straight handle upward.

[0006] As a further improvement of the technical solution, the lifting device includes a mounting ring, which is fixedly mounted on the shielding barrel, and a turbine is rotatably connected inside the mounting ring, a lifting ring is arranged on the lower side of the mounting ring, and the grab hook is arranged on the lower side of the lifting ring.

[0007] As a further improvement of the technical solution, a mounting plate is fixed on the lower side of the turbine, the mounting plate is arranged on the upper side of the lifting ring, and pulley blocks are installed on the side walls between the mounting plate and the lifting ring, the two pulley blocks are connected by a fiber rope, and one end of the fiber rope passes through the top of the turbine and is connected to a rope winch, and the rope winch pulls and reels the fiber rope.

[0008] As a further improvement of the present technical solution, the rotary drive assembly includes a screw rotatably installed on the top of the shielding barrel, a rotating handle is installed at one end of the screw, and a driving motor is installed at the other end of the screw. The screw and the turbine thread are meshed, and when the screw rotates, it drives the turbine to rotate inside the mounting ring, and the rotating turbine drives the mounting plate and the hanging ring to rotate inside the shielding barrel.

[0009] As a further improvement of the present technical solution, the grab hook includes a hook wall, the top of which is fixed to the lower side of the lifting ring, a placement groove is symmetrically provided on the hook wall, a sliding entrance is provided on one side of the placement groove, and the sliding entrance passes through the bottom of the hook wall.

[0010] As a further improvement of the present technical solution, the two sliding openings on the hook wall are centrally symmetrical along the central axis of the hook wall, the two sliding openings divide the bottom of the hook wall into two parts, and the bottoms of the two parts are both provided with guide surfaces, which are arc-shaped V-shaped structures.

[0011] As a further improvement of the present technical solution, the size of the sliding entrance is larger than the diameter of the flat handle, and an upwardly inclined blocking block is fixed at the bottom of the placement groove near the sliding entrance, the size between the top of the blocking block and the top of the placement groove is larger than the diameter of the flat handle, and the blocking block prevents the flat handle from sliding into the sliding entrance.

[0012] As a further improvement of the technical solution, there is a height difference between the two guide surfaces. The flat handle is guided by the guide surface and slides into the interior of the placement groove through the sliding entrance. The flat handle entering the placement groove is hooked with the placement groove. When the grab hook moves up, the flat handle moves up with the grab hook.

[0013] The second object of the present invention is to provide a method for operating a portable operating tool including the above-mentioned waste filter element shielding transport container, comprising the following method steps:

[0014] S1. First, move the rope winch to one side of the shielding barrel, then put the grab hook and the lifting ring into the shielding barrel, and then install the mounting ring and the screw on the shielding barrel. The rope winch loosens the fiber rope, and the lifting ring drives the grab hook to move downward;

[0015] S2. After the hook wall contacts the one-shaped handle, the hook continues to move downward, so that the side wall of the guide surface contacts the one-shaped handle. Then, under the action of gravity, the hook causes the waste filter element to slide along the track of the guide surface. At this time, the hook drives the lifting ring to rotate inside the shield barrel, and the one-shaped handle guided by the guide surface enters the sliding entrance. When the side wall of the one-shaped handle contacts the top side wall of the placement groove, the one-shaped handle receives the hook wall. At this time, the fiber rope is in a loose state, and the rope twister stops loosening the fiber rope.

[0016] S3, rotating the rotary drive assembly, so that the rotary drive assembly drives the lifting ring and the grab hook to rotate together. During the rotation of the grab hook, the flat handle moves in the placement slot, so that the flat handle is away from the sliding entrance. The flat handle contacts the side wall of the placement slot away from the sliding entrance. At this time, the rope twister stirs the fiber rope, so that the fiber rope pulls the grab hook to move upward;

[0017] S4. When the grab hook is not hooked with the flat handle for the first time, the lifting device is rotated 90 degrees by rotating the driving assembly, and then the grab hook is lowered to connect the grab hook with the flat handle.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the portable operating tool for the shielding transport container of the waste filter element and the use method thereof, the fiber rope is released by the rope twister, so that the lifting ring can slide down inside the shielding barrel, so that the grab hook gradually approaches the one-shaped handle, and after the grab hook contacts the one-shaped handle, the grab hook rotates according to the position of the one-shaped handle, so that the one-shaped handle enters the sliding entrance. When the grab hook is completely received by the one-shaped handle, the fiber rope is in a loose state, and the rope twister reels the fiber rope at this time, so that the fiber rope is in a state of releasing the lifting ring and moving the grab hook downward. At this time, by rotating the rotary drive component, the rotary drive component drives the turbine to rotate, and the rotating turbine drives the mounting ring to rotate, and the rotating mounting ring drives the lifting ring and the grab hook to rotate through the fiber rope, so that the one-shaped handle is away from the sliding entrance inside the placement groove, and then the fiber rope is reeled in by the rope twister, so that the one-shaped handle contacts the bottom of the placement groove, and the grab hook pulls the one-shaped handle to catch the waste filter element. The waste filter element is grabbed in this way to improve the accuracy of grabbing the waste filter element and avoid the trouble of subsequent manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0040] During normal use, the waste filter element 6 will be set inside the shielding barrel 4, with a distance between the top of the waste filter element 6 and the top of the shielding barrel 4. At the same time, a filter element middle cavity 62 is set in the middle of the waste filter element 6, and a flat handle 61 is installed on the upper side of the filter element middle cavity 62, so that the waste filter element 6 can be easily pulled out of the shielding barrel 4 and the accuracy of grabbing the flat handle 61 is improved.

[0041] See also Figure 1-Figure 11As shown, one of the purposes of the present invention is to provide a portable operating tool for a shielded transport container for waste filter elements, including a rope winch 1, the rope winch 1 including a winch and a wire rope guide bracket installed on the upper side of the winch, a battery pack is installed on the lower side of the winch, the battery pack provides power to the winch, a plurality of pulleys are arranged on the wire rope guide bracket, and a lifting device 2 is arranged at one end of the rope winch 1, that is, the lifting device 2 is arranged on one side of the wire rope guide bracket, the rope winch 1 is arranged on one side of the shielding barrel 4, the lifting device 2 is arranged on the upper side of the shielding barrel 4, and one end thereof is arranged inside the shielding barrel 4, and the lifting device 2 is arranged on the inner side of the shielding barrel 4. A grab hook 5 is provided at the lower side of the device 2, and a tension sensor is installed on the wire rope guide bracket. The tension sensor detects the tension of the lifting device 2 pulling the grab hook 5. By detecting the tension on the grab hook 5, it is determined whether the grab hook 5 is hooked on the flat handle 61. When the grab hook 5 is hooked on the flat handle 61, the tension value on the tension sensor will increase, which means that the grab hook 5 is hooked on the waste filter element 6. A depth sensor is installed on the wire rope guide bracket. The depth sensor is used to measure the depth distance of the grab hook 5 descending. The rope twister 1 is used to drive the grab hook 5 and part of the lifting device 2 to move up and down. During the downward movement of the hook 5, the grab hook 5 and the rope twister 1 enter the interior of the shielding barrel 4, so that the grab hook 5 is hooked with the straight handle 61 set inside the shielding barrel 4, and a rotating drive component 3 is set on one side of the lifting device 2. The rotating drive component 3 drives the lifting device 2 to rotate when rotating. At the same time, two limit switches are installed on the side of the lifting device 2. When the rotating drive component 3 drives the lifting device 2 to rotate a certain angle, the rotating drive component 3 is shut down by the limit switch, so that the rotating drive component 3 drives the lifting device 2 to rotate at a fixed angle, wherein the connection between the two limit switches and the central axis of the lifting device 2 The line angle is 90 degrees. During the rotation of the lifting device 2, the grab hook 5 rotates with the lifting device 2. At the same time, during the descent of the grab hook 5, the grab hook 5 adjusts its position according to the position of the handle 61, and is driven by the rotating drive component 3 to hook and engage the grab hook 5 and the handle 61, so that the grab hook 5 hooks the handle 61. After the grab hook 5 and the handle 61 are hooked and engaged, the rope twister 1 pulls the lifting device 2 again, so that the lifting device 2 drives the grab hook 5, so that the grab hook 5 pulls the handle 61 upward, so that the handle 61 drives the waste filter element 6 to move upward inside the shielding barrel 4.

[0042] The rope winch 1 drives the grab hook 5 close to the flat handle 61. During the movement of the grab hook 5, the tension sensor detects the tension of the lifting device 2 pulling the grab hook 5, and the depth sensor detects the depth of the downward movement of the grab hook 5. When the grab hook 5 contacts the flat handle 61, the flat handle 61 supports the grab hook 5, and the tension value on the tension sensor decreases. At this time, the lifting device 2 is driven to rotate by the rotating drive component 3, so that the grab hook 5 rotates with the lifting device 2, so that the grab hook 5 and the flat handle 61 are hooked and locked, and then the rope winch 1 is used to pull the lifting device 2, so that the grab hook 5 moves up with the lifting device 2. When the grab hook 5 moves up too much, the During the process, if the tension value on the tension sensor changes back to the value of pulling the grab hook 5 alone, it means that the grab hook 5 and the flat handle 61 are not hooked. At this time, the rotating drive component 3 drives the lifting device 2 to rotate 90 degrees, so that the angle at which the grab hook 5 grabs the flat handle 61 changes. At this time, the rope winch 1 drives the grab hook 5 to move down, so that the grab hook 5 is close to the flat handle 61, and after the tension sensor value is reduced, the rotating drive component 3 drives the lifting device 2 to rotate 90 degrees, so that the grab hook 5 and the flat handle 61 are hooked. At this time, the rope winch 1 drives the grab hook 5 to move up, so that the grab hook 5 pulls the waste filter element 6 up inside the shielding barrel 4.

[0043] By controlling the position of the grab hook 5, the grab hook 5 can hook the straight handle 61 100% at most twice, eliminating the trouble of failing to hook the waste filter element 6 many times in the past, improving the accuracy of the connection between the grab hook 5 and the straight handle 61, speeding up the hooking speed of the waste filter element 6, and also eliminating manual operation, reducing the radiation dose exposed to the operator.

[0044] The structures of the lifting device 2, the rotating drive assembly 3 and the grab hook 5 are detailed below. The lifting device 2 includes a mounting ring 21, which is fixedly mounted on the shield barrel 4, and a turbine 22 is rotatably connected inside the mounting ring 21. A mounting plate 23 is fixed to the lower side of the turbine 22. A lifting ring 24 is arranged on the lower side of the mounting ring 21, and the mounting plate 23 is arranged on the upper side of the lifting ring 24. The grab hook 5 is arranged on the lower side of the lifting ring 24. At the same time, a pulley block 25 is installed on the side wall between the mounting plate 23 and the lifting ring 24. The two pulley blocks 25 are connected by a fiber rope 26. The pulley block 25 consists of four rollers, and three of the rollers are arranged in a finished product shape, and the other roller is arranged in the middle. The rollers on the two pulley blocks 25 are connected together by reciprocating bending of the fiber rope 26. At the same time, one end of the fiber rope 26 passes through the top of the turbine 22 and is connected to the rope twister 1. The fiber rope 26 passes through the turbine The position 22 is set in the middle of the turbine 22, and the rope winch 1 pulls and reels the fiber rope 26. In the process of connecting the fiber rope 26 and the rope winch 1, first, one end of the fiber rope 26 is S-shaped and passes through several pulleys on the wire rope guide bracket, and is connected to the winch after the fiber rope 26 passes through the pulley. At the same time, the tension sensor and the depth sensor are in contact with the fiber rope 26 passing through the wire rope guide bracket. The tension sensor detects the tension on the fiber rope 26 to obtain the tension of the fiber rope 26 pulling the grab hook 5. The depth sensor calculates the moving distance of the grab hook 5 in the vertical height by detecting the moving distance of the fiber rope 26. The winch drives the fiber rope 26 to move during the rotation process. When the winch reels the fiber rope 26, the fiber rope 26 pulls the lifting ring 24 to move the lifting ring 24 upward. When the winch loosens the fiber rope 26, the fiber rope 26 drives the lifting ring 24 to move downward.

[0045] The rotary drive assembly 3 includes a screw rod 32 rotatably mounted on the top of the shielding barrel 4, a rotating handle 31 is mounted on one end of the screw rod 32, and a driving motor is mounted on the other end of the screw rod 32. The screw rod 32 is threadedly engaged with the turbine 22. When the screw rod 32 rotates, it drives the turbine 22 to rotate inside the mounting ring 21. The rotating turbine 22 drives the mounting disk 23 and the lifting ring 24 to rotate inside the shielding barrel 4. When the lifting ring 24 rotates, the grab hook 5 also rotates with the lifting ring 24. When the mounting disk 23 rotates, if the grab hook 5 contacts the one-shaped handle 61, and the fiber rope 26 between the mounting disk 23 and the lifting ring 24 is in a loose state, the lifting ring 24 and the grab hook 5 will not rotate with the mounting disk 23. When the fiber rope 26 between the mounting disk 23 and the lifting ring 24 is in a taut state, the fiber rope 26 pulls the lifting ring 24 and the grab hook 5 into suspension. At this time, when the mounting disk 23 rotates, the lifting ring 24 will rotate with the mounting disk 23 driven by the fiber rope 26.

[0046] The grab hook 5 includes a hook wall 51, which is a circular tubular structure. The hook wall 51 can be placed inside the filter element cavity 62. The top of the hook wall 51 is fixed to the lower side of the lifting ring 24. A placement groove 52 is centrally symmetrically provided on the hook wall 51. A sliding entrance is provided on one side of the placement groove 52. The sliding entrance passes through the bottom of the hook wall 51. The two sliding entrances on the hook wall 51 are centrally symmetrical along the central axis of the hook wall 51. The two sliding entrances divide the bottom of the hook wall 51 into two parts, and the bottoms of the two parts are both provided with guiding surfaces 53. The guiding surface 53 is an arc-shaped V-shaped structure, so that the lower side of the hook wall 51 forms two sharp corners. At the same time, the guiding surface 53 will guide the object toward the direction close to the sliding entrance, and the V-shaped guiding surface 53 will guide the one-word handle 61 so that the two ends of the one-word handle 61 can accurately enter the placement groove 52, so that the placement groove 52 can pull the one-word handle 61.

[0047] At the same time, the size of the sliding entrance is larger than the diameter of the one-shaped handle 61, so that when the one-shaped handle 61 enters the sliding entrance, the one-shaped handle 61 can enter the placement groove 52 through the sliding entrance, and there is a height difference between the two guide surfaces 53, that is, the bottom of the two guide surfaces 53 is at the high end and the bottom end, and the one-shaped handle 61 enters the interior of the placement groove 52 through the sliding entrance under the guidance of the guide surface 53, and the one-shaped handle 61 entering the placement groove 52 is hooked with the placement groove 52. When the grab hook 5 moves up, the one-shaped handle 61 moves up with the grab hook 5. At the same time, an upwardly inclined blocking block 54 is fixed at the position near the sliding entrance at the bottom of the placement groove 52. The size between the top of the blocking block 54 and the top of the placement groove 52 is larger than the diameter of the one-shaped handle 61. The blocking block 54 blocks the one-shaped handle 61 from sliding into the sliding entrance, thereby ensuring that when the grab hook 5 pulls the one-shaped handle 61, the one-shaped handle 61 will not fall off the grab hook 5, thereby improving the stability of the grab hook 5 pulling the waste filter element 6.

[0048] When the device is in use, the rope twister 1 is moved to one side of the shielding barrel 4, and then the grab hook 5 and the lifting ring 24 are placed inside the shielding barrel 4, and then the mounting ring 21 and the screw 32 are installed on the shielding barrel 4. The rope twister 1 loosens the fiber rope 26, so that the lifting ring 24 drives the grab hook 5 to move downward, and the tension sensor detects the tension on the fiber rope 26, and the depth sensor detects the distance moved by the fiber rope 26. When the hook wall 51 contacts the one-shaped handle 61, the grab hook 5 continues to move downward, so that the side wall of the guide surface 53 contacts the one-shaped handle 61, and then the grab hook 5 is affected by gravity, which will cause the waste to pass through. The filter element 6 slides along the trajectory of the guide surface 53. At this time, the grab hook 5 drives the lifting ring 24 to rotate inside the shielding barrel 4. The flat handle 61 guided by the guide surface 53 enters the sliding entrance. When the side wall of the flat handle 61 contacts the top side wall of the placement groove 52, the flat handle 61 supports the hook wall 51, and the value on the tension sensor decreases. At this time, the fiber rope 26 is in a loose state. At this time, the rope winch 1 stops loosening the fiber rope 26 and pulls up the fiber rope 26, so that the value of the tension sensor is restored to the value of pulling the grab hook 5 alone.

[0049] At this time, the driving motor at one end of the screw rod 32 is controlled to drive the screw rod 32 to rotate or the screw rod 32 is driven to rotate by the rotating handle 31, so that the screw rod 32 drives the turbine 22 to rotate in the mounting ring 21. During the rotation of the turbine 22, the mounting plate 23 drives the lifting ring 24 and the grab hook 5 to rotate together through the fiber rope 26 between the mounting plate 23 and the lifting ring 24. At this time, during the rotation of the grab hook 5, the straight handle 61 moves in the placement groove 52, so that the straight handle 61 is away from the sliding entrance, and the turbine 22 rotates 45-60 degrees. 90 degrees, the straight handle 61 will contact the side wall of the placement groove 52 away from the sliding entrance. At this time, the rope twister 1 stirs the fiber rope 26, so that the fiber rope 26 pulls the grab hook 5 to move up. At this time, the straight handle 61 contacts the lower side wall of the placement groove 52, and the blocking block 54 blocks the straight handle 61, so that the straight handle 61 cannot enter the sliding entrance. In the process of the grab hook 5 following the lifting ring 24 to move up, the waste filter element 6 is pulled and moves up with the grab hook 5, so as to pull the waste filter element 6.

[0050] When the grab hook 5 is not hooked with the flat handle 61 for the first time, the lifting device 2 is rotated 90 degrees by the rotating drive component 3, and then the grab hook 5 is lowered to connect the grab hook 5 with the flat handle 61. By controlling the position of the grab hook 5, the grab hook 5 can hook the flat handle 61 100% at most twice, eliminating the trouble of failing to hook the waste filter element 6 many times in the past, improving the accuracy of the connection between the grab hook 5 and the flat handle 61, speeding up the hooking speed of the waste filter element 6, and also eliminating manual operation, reducing the radiation dose exposed to the operator.

[0051] The second object of the present invention is to provide a method for operating a portable operating tool including the above-mentioned waste filter element shielding transport container, comprising the following method steps:

[0052] S1. First, move the rope twister 1 to one side of the shield barrel 4, then put the grab hook 5 and the lifting ring 24 into the shield barrel 4, and then install the mounting ring 21 and the screw 32 on the shield barrel 4. The rope twister 1 loosens the fiber rope 26, so that the lifting ring 24 drives the grab hook 5 to move downward;

[0053] S2. After the hook wall 51 contacts the one-way handle 61, the hook 5 continues to move downward, so that the side wall of the guide surface 53 contacts the one-way handle 61. Then, under the action of gravity, the hook 5 causes the waste filter element 6 to slide along the track of the guide surface 53. At this time, the hook 5 drives the lifting ring 24 to rotate inside the shield barrel 4, and the one-way handle 61 guided by the guide surface 53 enters the sliding entrance. When the side wall of the one-way handle 61 contacts the top side wall of the placement groove 52, the one-way handle 61 receives the hook wall 51. At this time, the fiber rope 26 is in a loose state, and the rope twister 1 stops loosening the fiber rope 26.

[0054] S3, rotating the rotary drive assembly 3, so that the rotary drive assembly 3 drives the lifting ring 24 and the grab hook 5 to rotate together. During the rotation of the grab hook 5, the straight handle 61 moves in the placement groove 52, so that the straight handle 61 is away from the sliding entrance. The straight handle 61 contacts the side wall of the placement groove 52 away from the sliding entrance. At this time, the rope twister 1 stirs the fiber rope 26, so that the fiber rope 26 pulls the grab hook 5 to move upward;

[0055] S4, when the grab hook 5 is not hooked with the flat handle 61 for the first time, the lifting device 2 is driven to rotate 90 degrees by the rotating driving assembly 3, and then the grab hook 5 is lowered to connect the grab hook 5 with the flat handle 61.

[0056] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
