Description

Technical Field

[0001] The present application belongs to the technical field of nuclear power plant loading and replacement, and specifically relates to a new fuel receiving tool storage device. Background Art

[0002] Receiving new fuel is an important task in the field of nuclear power plant refueling technology, providing new fuel assemblies for each overhaul and refueling. Receiving new fuel includes unloading fuel containers, tipping fuel containers vertically, unpacking operations, and grabbing and lifting assembly key operations. Among them, the unpacking operation requires driving an aerial vehicle to operate at a height of 8m. It requires the cooperation of the unpacker and the operator, and frequently uses many special wrenches to unpack the fuel container, which is a repetitive operation step. If the unpacking operation is not in place or the tool falls accidentally, it will cause scratches on the fuel assembly and accidental injuries to personnel. It is one of the first important steps in the entire new fuel reception.

[0003] In order to ensure the safety of unpacking new fuel for nuclear power plants, the traditional method uses a tool anti-drop rope with the entire tool kit to fix it to the aerial vehicle to prevent the tools from falling. Since special tools need to be used frequently and repeatedly, many tool anti-drop ropes often become entangled in a "twisted" shape during use, resulting in the tool being pulled by the anti-drop rope and unable to be placed on the fuel container door. This seriously confuses the operator's line of sight to take the tool, and the unpacking operation cannot proceed smoothly. It is often necessary to pause and unwind the tool rope before continuing the unpacking operation, which easily causes the tool to become detached from the anti-drop rope. In addition, the tools are arranged on the inside of the aerial vehicle, which seriously occupies the standing space of the operator and the unpacker. There is a risk of accidentally touching the tool and causing it to fall from a height, and there is a safety hazard of accidental injury to people caused by the tool falling. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] At least one embodiment of the present application provides a new fuel receiving tool storage device 11, which is suitable for the unified and independent storage of special tools during the new fuel receiving period of a nuclear power plant. Figure 1 The new fuel receiving tool storage device 11 includes a locking nut 1, a telescopic bracket 2 connected to the locking nut 1, a connecting block 4 that cooperates with a fastening device 3 and extends in a vertical direction, a tool storage module 5, and a sliding gasket 6. The tool storage module 5 is used for tool storage. The telescopic bracket 2 is used to adapt to aerial vehicles 12 of different sizes by contracting or extending the clamping distance. The sliding gasket 6 is used for sliding adjustment. The connecting block 4 and the telescopic bracket 2 are tightly fitted through the fastening nut and the sliding gasket 6.

[0023] It should be noted that the connection block 4 can be connected to the tool storage module 5 by bolts, and the connection block 4 and the tool storage module 5 can extend into one body in the same horizontal direction.

[0024] like Figure 2As shown, the telescopic bracket 2 is pushed to the rightmost side, at which time the clamping distance of the new fuel receiving tool storage device 11 is at the shortest position, as shown in FIG. Figure 3 As shown, the telescopic bracket 2 is pushed to the far left, and the clamping distance of the new fuel receiving tool storage device 11 is at the longest state. It can be adjusted and tightened as needed on site, so that the device can achieve the desired effect. The embodiment of the present application adopts the technical means of adjustable clamping distance, and realizes the technical effect of being applicable to aerial vehicles of different external dimensions.

[0025] According to the technical solution provided in the embodiment of the present application, a mechanically adjustable new fuel receiving tool storage device is designed. The clamping distance is expanded and reduced by the telescopic bracket 2 to adapt to different types of aerial vehicles, thereby ensuring the practicality of the damaged spare vehicle of the aerial vehicle. The practical scope is wider and it is installed on the outside of the aerial vehicle fence to save the standing space for people inside the aerial vehicle to the greatest extent, and avoid the phenomenon of accidental drop of tools due to accidental contact by people. The tool storage module 5 is installed and stored in partitions according to the frequency of use, which is convenient for the operator to take. The entire device is fixed to the aerial vehicle through the fastening device 3. The bolts of the fastening device 3 are slightly loosened, and the entire device can be moved in the front and rear directions of the aerial vehicle fence. It has the function of preventing accidental disengagement and falling. The entire device can be removed by completely loosening the fixed top screw to the extreme position.

[0026] In at least one embodiment of the present application, the locking nut 1, the fastening device 3 and the sliding gasket 6 are made of stainless steel, and the connecting block 4 and the tool storage module 5 are made of aluminum alloy. In this way, by using lightweight aluminum alloy for the connecting block 4 and the tool storage module 5, the overall weight can be reduced, high-altitude falling can be avoided, and safety can be improved.

[0027] It should be noted that, except for the locking nut 1, the sliding gasket 6, the fastening device 3 and the attached fastening screws which are made of stainless steel, all other materials can be made of lightweight aluminum alloy.

[0028] In at least one embodiment of the present application, the connecting block 4 and the tool storage module 5 are welded together to maintain the same level. In this way, the tool storage module 5 is welded together with the connecting block 4, and the connecting block 4 remains stationary so that the tool storage module 5 always fits tightly against the side of the railing of the aerial vehicle 12.

[0029] In at least one embodiment of the present application, the connection block 4 is drilled and tapped inside, the connection block 4 is connected to the telescopic bracket 2 by bolts, the top of the connection block 4 is fastened by a locking nut 1, and the sliding gasket 6 is connected to the connection block 4 through a hole through which the bolts are passed. In this way, the adjustment distance can be controlled, and the fastening device 3 is finally responsible for fixing the entire device to the aerial work vehicle.

[0030] In at least one embodiment of the present application, the telescopic bracket 2 is an L-shaped structure as a whole, and two waist-shaped holes of different lengths are opened on the surface of the telescopic bracket 2. The upper surface of the connecting block 4 is penetrated by three threads and tightly fits with the telescopic bracket 2 through the fastening nut and the sliding gasket 6.

[0031] Therefore, a hexagon socket bolt enters from the lower surface of the connecting block 4 and passes through the first waist-shaped hole of the telescopic bracket 2 to form a matching lock with the locking nut 1. The sliding gasket 6 is installed to the upper surface of the second waist-shaped hole of the telescopic bracket 2. Two hexagon socket bolts pass through the upper surface of the sliding gasket 6 and are screwed into the remaining two threads of the connecting port to provide left and right sliding limits for the entire telescopic bracket 2. The position of the telescopic bracket 2 can be adjusted by simply loosening the fastening nut, which is convenient for movement.

[0032] In at least one embodiment of the present application, two bolts with butterfly handles are designed inside the fastening device 3 and are screwed to the L-side surface of the telescopic bracket 2 .

[0033] Thus, the fastening device 3 has a locking and fixing function, and locking and removal are achieved by screwing in and out two bolts with butterfly handles, without any wrench operation. Since the bolts have a blocking function, the entire device will not fall off even if they are not screwed into place. In addition, by loosening the fastening device 3, it can be freely moved horizontally to a suitable position for the operator. The embodiment of the present application adopts a butterfly double-bolt fastening device 3, which achieves the technical effect of smooth lateral movement of the entire device and anti-falling.

[0034] In at least one embodiment of the present application, one side of the connecting block 4 is connected to the tool storage module 5, the top of the connecting block 4 is connected to the telescopic bracket 2, and the other side wall vertical plate of the connecting block 4 is linearly cut to form an integral body with the connecting block 4.

[0035] Therefore, the side wall vertical plate provides a reaction force for the fastening device 3, provides a certain support effect for the storage device, and provides a sliding track for the telescopic bracket 2.

[0036] In at least one embodiment of the present application, the tool storage module 5 is individually processed according to the external dimensions of various commonly used tools. In this way, the tool storage module 5 adopts the technical means of classified storage, achieving the technical effect of using the tool anti-fall rope without entanglement.

[0037] In at least one embodiment of the present application, the tool storage module 5 includes a scissors storage module 7, a rotary lock storage module 8, a T-wrench storage module 9 and a socket wrench storage module 10 which are integrated into one body.

[0038] In the existing scheme, the tool bag is stored inside the aerial vehicle, which requires a large space to affect the operator's position and the tool anti-fall rope is easily entangled, so it is not possible to serve the operator safely and quickly. The tool storage module 5 in the above embodiment can be made into a scissors storage module 7, a slewing lock storage module 8, a T-type wrench storage module 9, and a socket wrench storage module 10 according to the outer dimensions of the required tools, assembled and fixed to the upper railing of the aerial vehicle, which can provide the operator with a safe and reliable tool storage position at any time without occupying the internal space of the aerial vehicle.

[0039] In at least one embodiment of the present application, the scissors storage module 7, the rotary lock storage module 8, the T-wrench storage module 9 and the socket wrench storage module 10 are arranged in sequence in the vertical direction.

[0040] Therefore, according to the order of using tools for receiving new fuel, the tool storage modules 5 are arranged in order according to the principle of opening the outer box first and then the inner box. First is the socket wrench storage module 10, T-wrench storage module 9, slewing lock storage module 8, and finally the scissors storage module 7, ensuring that the operator selects tools in a certain order to avoid the tool anti-fall ropes from being entangled with each other.
