Description

Technical Field

[0001] The present invention relates to the technical field of inspection, maintenance and repair of nuclear power plants, and particularly to a pipe suspension device. Background Art

[0002] In order to ensure the safe operation of nuclear power plants, it is necessary to maintain and repair a wide variety of equipment in nuclear power plants. However, due to the presence of high-dose radioactive substances in the radiation pollution control area within the nuclear power plant, the harm of high radiation to humans is irreversible, and radioactive substances exist in the air. Direct breathing will cause internal contamination of personnel. Therefore, when personnel carry out maintenance and repair operations, they need to use airtight suits and air masks to reduce the radiation dose and protect the health of personnel.

[0003] When using airtight suits and air masks, an oxygen supply gas source pipe is connected. One end of the gas source pipe is connected to the gas source, and the other end is connected to the airtight suit or the air mask. When personnel wear airtight suits and / or air masks to work, the gas source pipe is often placed nearby on equipment brackets or walls. Personnel need to always pay attention to the position of the gas source pipe to avoid problems such as slipping, contamination, fracture, and damage of the gas source pipe due to excessive movement distance or working amplitude. Especially in a more complex working environment, the above problems are more likely to occur. And the damage of the gas source pipe will cause the operator to inhale radioactive contaminated gas, posing a risk of internal contamination of personnel, which not only affects the health of personnel, but also increases the working time and prolongs the construction period by replacing new airtight suits and air masks. Moreover, airtight suits and air masks are expensive, and they must be replaced separately after contamination, resulting in waste of resources and increased costs. Therefore, when the gas source pipe slips, gets contaminated, damaged, etc. when personnel wear airtight suits and air masks to work, it will lead to relatively serious consequences.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Before the technical solution of the pipe body suspension device provided in the embodiments of the present application was proposed, the inventors of the present application had experimented with the following solutions: 1) using tape to stick the gas source pipe to the equipment bracket or wall; 2) using a rope such as a thin hemp rope to tie the gas source pipe to the equipment bracket or wall.

[0034] However, the inventors found that the above solutions had significant drawbacks during the experiment: 1) Using tape for sticking or using a rope such as a thin hemp rope for tying took a relatively long time and required preparation of materials before the operation, which was cumbersome and affected the progress of the main operation; 2) The reliability was low, and during the operation of personnel, it was inevitable to pull or drag the gas source pipe, resulting in adverse consequences such as the gas source pipe falling or even being damaged; 3) Tape, thin hemp rope, etc. increased the generation of radioactive waste and were prone to polluting the equipment, resulting in the risk of introducing foreign objects into the equipment; 4) The flexibility was poor. After the gas source pipe was stuck with tape or tied with a rope such as a thin hemp rope, it could not be moved and could not be moved according to the operation needs.

[0035] Please refer to Figures 1 to 3 , the embodiments of the present application provide a pipe body suspension device 100 for detachably suspending a gas source pipe connected to a gas suit and / or a gas mask, especially for suspending the joint of the gas source pipe, to prevent problems such as the gas source pipe and its joint slipping, falling off, or dropping, resulting in pollution, fracture, damage, etc. The pipe body suspension device 100 includes a support body 10 and a suspension mechanism 20, where:

[0036] The support body 10 functions to support the suspension mechanism 20 and the entire pipe body suspension device 100. When the support body 10 is supported on an object such as the ground or equipment, there is a certain distance between the suspension mechanism 20 and the ground or equipment, so that there is a certain distance between the pipe body suspended by the suspension mechanism 20 and the ground or equipment, preventing the pipe body from being contaminated or damaged.

[0037] The suspension mechanism 20 is provided on the support body 10, and the suspension mechanism 20 has at least one locking portion 21 for suspending the pipe body; at least one locking portion 21 has a locked state and a loose state. In the locked state, the locking portion 21 can lock the pipe body to suspend the pipe body, and in the loose state, the locking portion 21 can loosen the pipe body to enable the pipe body to move freely.

[0038] The pipe body suspension device provided by the embodiment of the present application, by providing the support body 10 and the suspension mechanism 20 provided on the support body 10, the support body 10 supports the suspension mechanism 20, and the suspension mechanism 20 supports the pipe body, and the suspension mechanism 20 is provided with at least one locking portion 21, and the locking portion 21 has a locked state and a loose state. When personnel wear an airtight suit and / or an air mask to enter a nuclear power plant for maintenance and repair operations, the air supply pipe connected to the airtight suit and / or the air mask can make the locking portion 21 in the locked state and be locked through the locking portion 21 for suspension. And when the air supply pipe is suspended on the locking portion 21, the joint connected to the air supply pipe can be supported or suspended on the locking portion 21 to prevent it from falling. It has high reliability, can effectively prevent the air supply pipe from slipping and causing problems such as contamination, fracture, and damage, reduce the risk of internal contamination of personnel, and improve the safety of the operation process; after the operation is completed, the locking portion 21 can be in the loose state to remove the air supply pipe. The suspension and disassembly are fast and convenient, simplifying the suspension process, and effectively avoiding the problem of affecting the progress of the main operation due to frequent preparation work consuming time; and during the operation process, according to the operation needs, the air supply pipe can be moved at any time by moving the pipe body suspension device, which is flexible and convenient, and can adapt to operations in various complex environments; personnel do not need to be distracted to always pay attention to the position of the air supply pipe during the operation, which can effectively improve work efficiency; and the air supply pipe is suspended by an independent pipe body suspension device, avoiding the use of tape, thin hemp rope, etc., thereby reducing the generation of radioactive waste and avoiding the risk of introducing foreign objects into the equipment.

[0039] In one embodiment, please refer to Figure 2 , the suspension mechanism 20 is detachably provided on the support body 10, which is convenient for the connection and disassembly between the suspension mechanism 20 and the support body 10.

[0040] Further, in one embodiment, please refer to Figure 2 and Figure 3, the suspension mechanism 20 has a first insertion portion 201, and the support body 10 has a first insertion mating portion 101. The first insertion portion 201 is inserted and mated with the first insertion mating portion 101 to connect the suspension mechanism 20 and the support body 10. With such a setting, it is convenient for the quick positioning and fast connection between the suspension mechanism 20 and the support body 10.

[0041] Specifically, the first insertion portion 201 is a first insertion post, and the first insertion mating portion 101 is a first insertion hole. The suspension mechanism 20 and the support body 10 are positioned and connected by inserting the first insertion post of the suspension mechanism 20 into the first insertion hole of the support body 10. Or the first insertion portion 201 is a second insertion hole, and the first insertion mating portion 101 is a second insertion post. The suspension mechanism 20 and the support body 10 are quickly positioned and connected by inserting the second insertion post of the support body 10 into the second insertion hole of the suspension mechanism 20.

[0042] Furthermore, in one embodiment, please refer to Figure 2 , when the first insertion portion 201 is a first insertion post and the first insertion mating portion 101 is a first insertion hole, a first through hole 102 (the first through hole 102 can be a threaded hole or a smooth through hole) communicating with the first insertion hole is formed on the support body 10. After the first insertion post of the suspension mechanism 20 is inserted into the first insertion hole of the support body 10, the first insertion post can be fixed to the support body 10 by a screw or a bolt passing through the first through hole and connecting with the first insertion post. A first hole body 2010 (the first hole body can be a blind hole or a through hole) can be formed on the first insertion post. After the screw, bolt or pin passes through the first through hole and then inserts into the first hole body 2010, the first insertion post is connected with the support body 10. Similarly, when the first insertion portion 201 is a second insertion hole and the first insertion mating portion 101 is a second insertion post, a second through hole (the second through hole can be a threaded hole or a smooth through hole) communicating with the second insertion hole can be provided on the suspension mechanism 20, and a second hole body (the second hole body can be a blind hole or a through hole) can be provided on the second insertion post.

[0043] It should be noted that the connection method between the suspension mechanism 20 and the support body 10 is not limited to this. Optionally, the suspension mechanism 20 can be connected to the support body 10 by detachable connection methods such as screws, bolts, and snap connections, and the suspension mechanism 20 can also be connected to the support body 10 by fixed connection methods such as welding.

[0044] In one embodiment, please refer to Figure 5 and Figure 6, the number of the suspension mechanisms 20 is at least two, and at least two suspension mechanisms 20 are all connected to the support body 10. With such a setting, the number of the suspension mechanisms 20 is increased, and more pipes can be suspended, which is convenient for suspending multiple gas source pipes by the same pipe suspension device, so as to facilitate adding gas source pipes according to the number of operation team members and requirements, and can make the arrangement of multiple gas source pipes more regular.

[0045] Further, in one embodiment, please refer to Figure 5 , one of the suspension mechanisms 20 is arranged on the support body 10, and the other suspension mechanisms 20 are sequentially stacked on the one suspension mechanism 20, and adjacent two suspension mechanisms 20 are detachably connected to each other. With such a setting, the multiple suspension mechanisms 20 are arranged on the support body 10 more regularly, and each suspension mechanism 20 has a different height, which is convenient for suspending the gas source pipes on the suspension mechanisms 20 at different heights according to the operation requirements.

[0046] Further, the suspension mechanisms 20 are coaxially arranged. The locking parts 21 of adjacent two suspension mechanisms 20 can be staggered by a certain distance to facilitate suspending the gas source pipes respectively. Of course, the positions of the locking parts 21 of adjacent two suspension mechanisms 20 can also correspond in sequence.

[0047] Further, in one embodiment, please refer to Figure 6 , the suspension mechanism 20 has a bottom 205 and a top 206. The bottom 205 of the suspension mechanism 20 is provided with a second insertion part 202, and the top 206 of the suspension mechanism 20 is provided with a second insertion mating part 203. The second insertion part 202 of one suspension mechanism 20 is inserted into the second insertion mating part 203 of another suspension mechanism 20 to connect the two suspension mechanisms 20. With such a setting, the sequential stacking of each suspension mechanism 20 can be quickly positioned and installed.

[0048] Specifically, the second insertion part 202 is a third insertion post, and the second insertion mating part 203 is a third insertion hole. The two suspension mechanisms 20 are positioned and connected by inserting the third insertion post of one suspension mechanism 20 into the third insertion hole of another suspension mechanism 20. Or the second insertion part 202 is a fourth insertion hole, and the second insertion mating part 203 is a fourth insertion post. The two suspension mechanisms 20 are positioned and connected by inserting the fourth insertion post of one suspension mechanism 20 into the fourth insertion hole of another suspension mechanism 20.

[0049] Further, in one embodiment, please refer to Figure 6, when the second plugging part 202 is a third plugging post and the second plugging and mating part 203 is a third plugging hole, a third through hole 204 (the third through hole 204 can be a threaded hole or a smooth through hole) communicating with the third plugging hole is arranged on the hanging mechanism 20. When the third plugging post of one hanging mechanism 20 is inserted into the third plugging hole of another hanging mechanism 20, the two hanging mechanisms 20 can be connected by screwing a screw or a bolt through the third through hole 204 and connecting it with the third plugging post. A third hole body 2020 (the third hole body can be a blind hole or a through hole) can be arranged on the third plugging post, and the two hanging mechanisms 20 can be connected by screwing a screw, a bolt or a pin through the third through hole 204 and then inserting it into the third hole body 2020. Further, the top of the support body 10 has a third plugging and mating part 103, and one hanging mechanism 20 is connected to the support body 10 by plugging and mating the second plugging part 202 of one hanging mechanism 20 with the third plugging and mating part 103. In this embodiment, the second plugging part 202 of one hanging mechanism 20 is equivalent to the first plugging part 201 in the above embodiment, and the third plugging and mating part 103 is equivalent to the first plugging and mating part 101 in the above embodiment.

[0050] It should be noted that the connection method between the hanging mechanisms 20 is not limited to this. Optionally, the hanging mechanism 20 can be connected to another hanging mechanism 20 by detachable connection methods such as screws, bolts, and snap connections, and the hanging mechanism 20 can also be connected to another hanging mechanism 20 by fixed connection methods such as welding.

[0051] In one embodiment, please refer to Figures 1 to 3 , the hanging mechanism 20 includes a connecting part 22, at least one arm part 23, and at least one locking part 21. The connecting part 22 is arranged on the support body 10 and is used to support the arm part 23. The arm part 23 has a first end 231 and a second end 232. The first end 231 of at least one arm part 23 is connected to the connecting part 22, and at least one locking part 21 is connected to the second end 232 of at least one arm part 23. With such an arrangement, there is a certain distance between the locking part 21 and the connecting part 22 through the arm part 23, so as to extend to the outside, which is beneficial for the locking part 21 to lock the hanging air source pipe, and it is also beneficial to arrange multiple locking parts by arranging multiple arm parts 23 circumferentially along the connecting part 22.

[0052] Further, multiple arm parts 23 are arranged, and the multiple arm parts 23 are distributed circumferentially along the connecting part 22. At least one locking part 21 is arranged at the second end 232 of each arm part 23, so that the hanging mechanism 20 has multiple locking parts 21 along its circumference, which is beneficial for locking multiple air source pipes simultaneously.

[0053] Further, in one embodiment, please refer to Figure 1 andFigure 4 , the locking portion 21 includes a fixing portion 211 and an opening / closing portion 212. The fixing portion 211 is connected to the second end 232 of the arm portion 23, and the fixing portion 211 has a first locking position 2110. The opening / closing portion 212 is pivotally connected to the fixing portion 211, and the opening / closing portion 212 has a second locking position 2120. Wherein, in the locked state, the opening / closing portion 212 is latched to the fixing portion 211 so that the first locking position 2110 and the second locking position 2120 relatively lock the pipe body. In the loosened state, the opening / closing portion 212 is opened from the fixing portion 211 so that the first locking position 2110 and the second locking position 2120 are separated to release the pipe body. With such a setting, through the cooperation of the opening / closing portion 212 and the fixing portion 211, the air source pipe can be quickly locked or loosened, which is convenient for personnel operation, facilitates the quick hanging and disassembly of the air source pipe, and has a reliable lock.

[0054] Specifically, the first locking position 2110 is a first groove with an arc-shaped cross-section, and the second locking position 2120 is a second groove with an arc-shaped cross-section. When the locking portion 21 is in the locked state, the first groove and the second groove are opposite and communicate to form a locking through-hole, thereby locking the air source pipe in the locking through-hole. It should be noted that the first locking position 2110 can also be a plane. When the locking portion 21 is in the locked state, the second groove of the second locking position 2120 is opposite to the first locking position 2110 of the plane to enclose a locking hole, thereby locking the air source pipe in the locking hole. The inner diameters of the locking through-hole and the locking hole are both greater than or equal to the outer diameter of the air source pipe to avoid squeezing the air source pipe and causing damage to the air source pipe. Further, the locking through-hole and the locking hole are arranged along the height direction of the support body 10, so that when the air source pipe is hung in the locking through-hole or the locking hole of the locking portion 21, the joint connected to the air source pipe can be supported above the locking portion 21 to prevent the joint connected to the air source pipe from falling to the ground and being contaminated and / or damaged.

[0055] Further, in one embodiment, please refer to Figure 1 , the locking portion 21 further includes a hinge 213. The hinge 213 has a first leaf plate and a second leaf plate that are rotatably connected. The first leaf plate is connected to the fixing portion 211, and the second leaf plate is connected to the opening / closing portion 212, so that the opening / closing portion 212 is rotatably connected to the fixing portion 211 through the hinge 213. With such a setting, the opening / closing portion 212 is pivotally connected to the fixing portion 211. Whether the opening / closing portion 212 is latched or opened from the fixing portion 211, the opening / closing portion 212 is always connected to the fixing portion 211, which can improve the convenience of the locking portion 21 for locking the air source pipe.

[0056] Further, in one embodiment, please refer to Figure 1, the locking portion 21 further includes a fastening portion 214, and the fastening portion 214 is configured to lock the opening and closing portion 212 and the fixing portion 211 when the opening and closing portion 212 is fastened to the fixing portion 211. Specifically, the fastening portion 214 includes at least one of a screw, a bolt, a clamp, and a locking clip. When the opening and closing portion 212 is detachably connected to the fixing portion 211, that is, the opening and closing portion 212 can be completely separated from the fixing portion 211, the fastening portion 214 can be a screw, a bolt, a clamp, etc. When the opening and closing portion 212 is fastened to the fixing portion 211, the opening and closing portion 212 and the fixing portion 211 can be connected by a screw or a bolt, or the opening and closing portion 212 and the fixing portion 211 can be clamped tightly by a clamp. When the opening and closing portion 212 is connected to the fixing portion 211 through a hinge 213, the fastening portion 214 can be a locking clip or a locking buckle connected to the fixing portion 211 and the opening and closing portion 212. When the opening and closing portion 212 is fastened to the fixing portion 211, locking by the locking clip or the locking buckle can prevent the opening and closing portion 212 from loosening from the fixing portion 211.

[0057] It should be noted that the structure of the locking portion 21 is not limited to the above structure. Optionally, the locking portion 21 can also be a clip or a clamp.

[0058] Furthermore, in one embodiment, please refer to Figure 1 , the suspension mechanism 20 further includes a flange portion 25. The flange portion 25 is connected to the second end 232 of the arm portion 23, and the fixing portion 211 is detachably connected to the flange portion 25, for example, by screws or bolts. Such a setting facilitates the disassembly and connection between the locking portion 21 and the flange portion 25. Specifically, the flange portion 25 can be a plate-like body or a sheet-like body, but is not limited thereto.

[0059] Furthermore, in one embodiment, please refer to Figure 3 , the connecting portion 22 includes a connecting column 221 and a connecting plate 222. The bottom of the connecting column 221 is disposed on the support body 10, and the connecting plate 222 is detachably disposed on the top of the connecting column 221, for example, by screws or bolts. Wherein, the first end 231 of at least one arm portion 23 is connected to the connecting plate 222, and multiple arm portions 23 can be evenly distributed around the connecting plate 222. The connecting plate 222 can be a circular plate, and the length direction of the arm portion 23 is perpendicular to the axis direction of the connecting plate 222. One end of the connecting column 221 can form a connecting flange, and the connecting plate 222 is detachably connected to the connecting flange.

[0060] Further, the second plugging portion 202 is disposed at one end of the connecting column 221 away from the connecting plate 222, and the second plugging and mating portion 203 is disposed on the connecting plate 222 and / or at one end of the connecting column 221 connected to the connecting plate 222. For example, when the second plugging and mating portion 203 is a third plugging hole, a through hole of the connecting plate penetrating the connecting plate 222 is formed on the connecting plate 222, and a connecting column hole body (the connecting column hole body may be a blind hole or a through hole) is formed at one end of the connecting column 221 connected to the connecting plate 222. The connecting column hole body communicates with the through hole of the connecting plate to form a third plugging hole. The third through hole 204 is formed on the connecting column 221 and communicates with the connecting column hole body.

[0061] In one embodiment, please refer to Figure 1 and Figure 2 , the support body 10 includes a base 11 and a support portion 12.
