Description

Technical Field

[0001] This utility model relates to the field of chemical drum unsealing technology, and in particular to a chemical container unsealing tool. Background Technology

[0002] In daily operation, nuclear power plants use boric acid as a neutron absorber to control the rate of nuclear reactions. The boric acid in nuclear power plants is typically stored in sealed chemical containers to ensure it remains uncontaminated and prevent moisture absorption and clumping.

[0003] Chemical drums are typically sealed using stainless steel clamps with clips, and barbed plastic pins are inserted into the clamps for safety. When unsealing a chemical drum, the plastic pins must be pulled out of the clamps, and then the clips on the stainless steel clamps must be pried open.

[0004] However, the current lack of properly designed unpacking tools makes it easy for plastic pins to fall off during disassembly. If these pins accidentally fall into equipment such as boron generators, they could cause serious incidents such as foreign objects entering the reactor. Utility Model Content

[0043] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0044] Please see Figures 1 to 5 One embodiment of this utility model provides a chemical container unsealing tool 100 for disassembling the clamp 200 of the chemical container and the pins 300 in the clamp 200.

[0045] The chemical container unsealing tool 100 includes a first handle assembly 10, a second handle assembly 20, a first pry bar 30, a stop 40, and a second pry bar 50. The first handle assembly 10 and the second handle assembly 20 are hinged together. The first pry bar 30 is located at the front end of the first handle assembly 10, the second pry bar 50 is located at the front end of the second handle assembly 20, and the stop 40 is located on the side of the first pry bar 30 away from the second pry bar 50, and a gap 42 is provided between the stop 40 and the first pry bar 30 to accommodate the head 302 of the insert 300.

[0046] The first handle assembly 10 is configured to allow rotation between a first angular position and a second angular position of the second handle assembly 20, wherein when rotated to the first angular position, the first pry bar 30 and the second pry bar 50 move closer to each other, and when rotated to the second angular position, the first pry bar 30 and the second pry bar 50 move further apart.

[0047] When removing pin 300:

[0048] The first handle assembly 10 rotates to a first angle position, the first pry bar 30 and the second pry bar 50 approach each other, the side of the second pry bar 50 away from the first pry bar 30 abuts against the surface of the clamp 200, the first pry bar 30 is positioned between the head 302 of the insert 300 and the surface of the clamp 200, and the stop 40 is positioned on the side of the head 302 of the insert 300 away from the first pry bar 30. Figure 1 and Figure 2 As shown.

[0049] The first handle assembly 10 rotates to the second angle position, and the first prying part 30 and the second prying part 50 move away from each other. The first prying part 30 acts on the head 302 of the insert 300 to pry the insert 300 off the surface of the clamp 200. Since the stop 40 is located on the side of the head 302 of the insert 300 away from the first prying part 30, the stop 40 can block the insert 300 and prevent the insert 300 from axially disengaging from the first prying part 30. Figure 3 As shown.

[0050] When removing clamp 200:

[0051] The first handle assembly 10 rotates to a first angle position, the first pry bar 30 and the second pry bar 50 approach each other, and the second pry bar 50 and the stop 40 extend into the snap-fit ​​gap of the clamp 200, as... Figure 4 As shown.

[0052] The first handle assembly 10 rotates to the second angle position, and the first pry part 30 and the second pry part 50 move away from each other to pry open the buckle of the clamp 200, as shown. Figure 5 As shown.

[0053] The first handle assembly 10 includes a first handle 12, a first anti-slip sleeve 14, and a first hinge seat 16.

[0054] The first handle 12 can be a straight handle extending along a straight line. The first handle 12 can be made of metal, such as iron, steel, aluminum alloy, etc. The first prying part 30 is located at the front end of the first handle 12, and the rear end of the first handle 12 is used for the operator to grip.

[0055] The first anti-slip sleeve 14 can be made of materials such as rubber, silicone, or plastic. The first anti-slip sleeve 14 covers the outer surface of the first handle 12, and its surface roughness is greater than that of the first handle 12, serving to provide anti-slip treatment for the first handle 12. The surface of the first anti-slip sleeve 14 may be provided with anti-slip textures to further improve its surface roughness and enhance its anti-slip performance.

[0056] The first hinge seat 16 can be made of metal, such as iron, steel, or aluminum alloy. The first hinge seat 16 is located at the front end of the first handle 12 and on the side of the first handle 12 closest to the second handle assembly 20. Specifically, the first hinge seat 16 can be fixed to the first handle 12 by welding. Depending on actual needs, it can also be fixed to the first handle 12 by fasteners such as screws or rivets, or integrally formed with the first handle 12 by casting, die casting, or other methods.

[0057] The first hinge 16 is hinged to the second handle assembly 20.

[0058] Please combine Figure 6 For reference, the second handle assembly 20 includes a second handle 22, a second anti-slip sleeve 24, and a second hinge seat 26.

[0059] The second handle 22 can be a straight handle extending in a straight line. It can be made of metal, such as iron, steel, aluminum alloy, etc. The second pry bar 50 is located at the front end of the second handle 22, and the rear end of the second handle 22 is used for the operator to grip.

[0060] The second anti-slip sleeve 24 can be made of materials such as rubber, silicone, or plastic. The second anti-slip sleeve 24 covers the outer surface of the second handle 22, and its surface roughness is greater than that of the second handle 22, serving to provide anti-slip treatment for the second handle 22. The surface of the second anti-slip sleeve 24 may be provided with anti-slip textures to further improve its surface roughness and enhance its anti-slip performance.

[0061] The second hinge seat 26 can be made of metal, such as iron, steel, or aluminum alloy. The second hinge seat 26 is located at the front end of the second handle 22 and is located on the side of the second handle 22 closest to the first handle 12, that is, on the side of the second handle 22 closest to the first handle assembly 10. Specifically, the second hinge seat 26 can be fixed to the second handle 22 by welding. Depending on actual needs, it can also be fixed to the second handle 22 by fasteners such as screws or rivets, or it can be integrally formed with the second handle 22 by casting, die casting, or other methods.

[0062] The second hinge 26 is hinged to the first hinge 16, that is, hinged to the first handle assembly 10. Specifically, the first hinge 16 can be hinged to the first hinge 16 by fixing rivets 60.

[0063] By providing a first hinge seat 16 on the first handle 12 and a second hinge seat 26 on the second handle 22, the hinge position can be shifted from the first handle 12 and the second handle 22 to the first hinge seat 16 and the second hinge seat 26, increasing the distance between the first handle 12 and the second handle 22, and preventing the first prying part 30 and the second prying part 50 from being misaligned or crossing. During the rotation of the first handle assembly 10 between the first angular position and the second angular position, the first prying part 30 and the first handle 12 are always located on the same side of the second prying part 50 and the second handle 22.

[0064] When the first handle assembly 10 rotates from the second angle position to the first angle position, the angle between the first handle 12 and the second handle 22 increases, that is, the angle between the first handle assembly 10 and the second handle assembly 20 increases, and the first prying part 30 and the second prying part 50 move closer to each other.

[0065] When the first handle assembly 10 rotates from the first angle position to the second angle position, the angle between the first handle 12 and the second handle 22 becomes smaller, that is, the angle between the first handle assembly 10 and the second handle assembly 20 becomes smaller, and the first prying part 30 and the second prying part 50 move away from each other.

[0066] Understandably, depending on actual needs, either the first hinge seat 16 or the second hinge seat 26 can be omitted. When the first hinge seat 16 is omitted, the first handle 12 is hinged to the second hinge seat 26. When the second hinge seat 26 is omitted, the second handle 22 is hinged to the first hinge seat 16.

[0067] The chemical container unsealing tool 100 also includes an elastic element 70. The elastic element 70 is disposed between the first handle assembly 10 and the second handle assembly 20. The elastic element 70 is used to accumulate elastic force when the first handle assembly 10 rotates from a first angular position to a second angular position, so as to drive the first handle assembly 10 to rotate from the second angular position to the first angular position when the elastic force is released.

[0068] The elastic element 70 can be a compression spring.

[0069] Please combine Figure 7 and Figure 8 For reference, the first handle assembly 10 may further include a first compression spring fixing part 18, which protrudes from the side of the first handle 12 near the second handle 22. One end of the compression spring abuts against the side of the first handle 12 near the second handle 22 and is sleeved on the outer periphery of the first compression spring fixing part 18.

[0070] The second handle assembly 20 may further include a second spring fixing part 28, which protrudes from the side of the second handle 22 near the first handle 12. The other end of the spring away from the first handle 12 abuts against the side of the second handle 22 near the first handle 12 and is sleeved on the outer periphery of the second spring fixing part 28.

[0071] By providing a first spring fixing part 18 and a second spring fixing part 28 on the first handle 12 and the second handle 22, the springs can be fixed and limited. When the first handle assembly 10 rotates from the first angle position to the second angle position, the first spring fixing part 18 and the second spring fixing part 28 abut against each other, preventing the first handle 12 from continuing to rotate toward the second handle 22, and preventing the first handle 12 and the second handle 22 from pinching and injuring the hand.

[0072] Please combine Figures 9 to 11 For reference, a pry transition portion 80 may be provided between the first pry portion 30 and the front end of the first handle portion 12, that is, a pry transition portion 80 may be provided between the first pry portion 30 and the first handle portion assembly 10.

[0073] The skid transition portion 80 can be made of metal, such as iron, steel, aluminum alloy, etc. The skid transition portion 80 bends and extends from the front end of the first handle portion 12 toward the second skid portion 50, that is, it bends and extends from the first handle portion assembly 10 toward the second skid portion 50. The first skid portion 30 is connected to the front end of the skid transition portion 80, that is, it is connected to the front end of the skid transition portion 80.

[0074] The transition part 80 of the pry bar can be fixed to the first pry bar 30 and / or the first handle 12 by welding. Depending on actual needs, it can also be fixed to the first pry bar 30 and / or the first handle 12 by fasteners such as screws and rivets, or integrally formed with the first pry bar 30 and / or the first handle 12 by casting, die casting or other methods.

[0075] The transition part 80 of the pry section is used to adjust the relative angle and position of the first pry section 30 and the first handle 12, so as to prevent the first pry section 30 and the second pry section 50 from being misaligned or crossing, to prevent hand injury, and to facilitate the application of force. At the same time, it can make the first pry section 30 and the second pry section 50 basically fit together when the first handle assembly 10 is rotated to the first angle position. The fit between the first pry section 30 and the second pry section 50 can control the overall thickness of the first pry section 30 and the second pry section 50, making it easy to insert into the gap between the head 302 of the insert 300 and the surface of the clamp 200.

[0076] The first pry bar 30 can be made of metal, such as iron, steel, or aluminum alloy. The first pry bar 30 can be generally forked in shape and has a first recess 32 for receiving the pin portion 304 of the insert 300.

[0077] When disassembling the insert 300, the first prying part 30 is placed between the head 302 of the insert 300 and the surface of the clamp 200, and the nail part 304 of the insert 300 is located within the range of the first clearance opening 32. This allows the first prying part 30 to be located directly below the head 302 of the insert 300. The contact area between the first prying part 30 and the head 302 of the insert 300 is large, making it easier to pry the insert 300 off the surface of the clamp 200.

[0078] The first clearance opening 32 is located at the front end of the first prying part 30. The length direction of the first clearance opening 32 is parallel to the length direction of the first prying part 30. The size of the first clearance opening 32 gradually decreases towards the rear, so that it can accommodate different sizes and specifications of the insert pins 300.

[0079] like Figure 9As shown, the front end of the first pry bar 30 near the stop 40 can be chamfered or rounded, which has a guiding function and can guide the head 302 of the insert 300 into the gap 42 between the first pry bar 30 and the stop 40.

[0080] The stop 40 can be made of metal, such as iron, steel, or aluminum alloy. The stop 40 is connected to the front end of the skid transition part 80. Specifically, it can be fixed to the skid transition part 80 by welding, or, depending on actual needs, it can be fixed to the skid transition part 80 by fasteners such as screws or rivets, or it can be integrally formed with the skid transition part 80 by casting, die casting, or other methods.

[0081] The front end of the stop 40 can extend beyond the front end of the first pry part 30 so that the stop 40 can be smoothly inserted into the buckle gap of the clamp 200 when the clamp 200 is disassembled.

[0082] like Figure 9 As shown, the front end of the stop 40 near the first pry bar 30 can be chamfered or rounded, which has a guiding function. It can guide the head 302 of the insert 300 into the gap 42 between the first pry bar 30 and the stop 40, or guide the stop 40 into the buckle gap of the clamp 200.

[0083] The second skid 50 can be made of metal, such as iron, steel, aluminum alloy, etc.

[0084] The front end of the first pry bar 30 can be flush with the front end of the second pry bar 50. Specifically, the second pry bar 50 can be fixed to the second handle 22 by welding, or, depending on actual needs, it can also be fixed to the second handle 22 by fasteners such as screws and rivets, or integrally formed with the second handle 22 by casting, die casting, or other methods.

[0085] The second pry bar 50 may be generally fork-shaped and has a second recess for receiving the pin portion 304 of the insert 300.

[0086] The structure of the second clearance opening 52 is basically the same as that of the first clearance opening 32. When the first handle assembly 10 is rotated to the first angle position, the second clearance opening 52 is aligned with the first clearance opening 32. When disassembling the pin 300, the first prying part 30 is placed between the head 302 of the pin 300 and the surface of the clamp 200, and the pin part 304 of the pin 300 is located within the range of the first clearance opening 32 and the second clearance opening 52. This allows the first prying part 30 and the second prying part 50 to be located directly below the head 302 of the pin 300 at the same time. The contact surface between the first prying part 30 and the head 302 of the pin 300 is large, and the contact surface between the second prying part 50 and the surface of the clamp 200 is large, making it easier to pry the pin 300 off the surface of the clamp 200.

[0087] Compared with the prior art, in the chemical container unsealing tool 100 provided in this embodiment of the utility model, when disassembling the insert 300: the first handle assembly 10 rotates to the first angle position, the first pry part 30 and the second pry part 50 approach each other, the side of the second pry part 50 away from the first pry part 30 abuts against the surface of the clamp 200, the first pry part 30 is placed between the head 302 of the insert 300 and the surface of the clamp 200, and the stop part 40 is placed on the side of the head 302 of the insert 300 away from the first pry part 30; the first handle assembly 10 rotates to the second angle position, the first pry part 30 and the second pry part 50 move away from each other, and the first pry part 30 acts on the head 302 of the insert 300 to pry the insert 300 off the surface of the clamp 200. When disassembling the clamp 200: the first handle assembly 10 rotates to a first angle position, the first pry part 30 and the second pry part 50 approach each other, and the second pry part 50 and the stop part 40 extend into the snap-fit ​​gap of the clamp 200; the first handle assembly 10 rotates to a second angle position, and the first pry part 30 and the second pry part 50 move away from each other to pry open the snap-fit ​​of the clamp 200. Since the stop part 40 is located on the side of the head 302 of the insert 300 away from the first pry part 30, the stop part 40 can block the insert 300 when disassembling the insert 300, preventing the insert 300 from detaching from the first pry part 30 axially, thereby solving the technical problem in the prior art that plastic inserts of chemical drums are easy to fall off during disassembly.

[0088] It should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above.
