Description

Technical Field

[0001] This invention relates to the field of nuclear reactor engineering technology, and in particular to a tripping device. Background Technology

[0002] High-temperature gas-cooled reactors (HTGRs), as an advanced type of nuclear reactor, possess advantages such as high safety and high outlet temperature, demonstrating enormous application potential in the production of radioactive isotopes. Irradiating specific target materials using a high-flux neutron field inside the reactor is a key method for producing medical and industrial isotopes.

[0003] In the online production of isotopes in a high-temperature gas-cooled reactor, a target containing target material is typically delivered to a designated location in the reactor core through a narrow channel for irradiation. A typical operating procedure is as follows: First, the target is connected to the end of a thin steel wire rope outside the reactor. Then, the wire rope is released using a traction device, and the target is slowly lowered to the designated irradiation position. Once the target is accurately in place, it is detached from the wire rope, and the wire rope is retrieved. After completing the predetermined irradiation cycle, the wire rope is released again, reconnected to the target, and finally, the target is hoisted out.

[0004] In the above process, due to the limited diameter and large depth of the narrow channel for conveying the target, how to reliably connect and disconnect the target and the wire rope within the narrow channel is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] To address this, this invention provides a locking and releasing device, comprising: a sleeve for connecting to a traction member; a sliding rod for connecting to a target member, the sliding rod being slidably engaged with the sleeve and capable of sliding into or out of the sleeve along its own axial direction during sliding; a locking component disposed on the sleeve, the locking component being capable of restricting the sliding rod from sliding out of the sleeve after the sliding rod has slid inwards a first preset distance; and an unlocking component disposed on the sliding rod, the unlocking component being capable of releasing the locking component from restricting the sliding rod during the process of the sliding rod sliding inwards a second preset distance and then sliding outwards from the sleeve.

[0007] In the interlocking and releasing device of this embodiment of the invention, the sleeve and the slide rod can be interlocked by the locking component during the process of sliding towards each other, and can be released by the unlocking component during the process of the sleeve and the slide rod continuing to slide towards each other and then away from each other.

[0008] In practical applications, the sleeve is connected to the traction component, such as a wire rope, and the slide rod is connected to the target component, such as a target. The sleeve moves downward under its own weight and the combined action of the additional counterweight. When the sleeve moves down to the point where the slide rod slides into the sleeve a first preset distance, the locking component engages, making the sleeve and the slide rod interlocked. At this time, lifting the sleeve will cause the slide rod and the target to move upward synchronously with the sleeve. When it is necessary to disengage, the sleeve is moved downward again. After the slide rod slides into the sleeve a second preset distance, the sleeve is lifted, and under the action of the unlocking component, the sleeve will separate from the slide rod.

[0009] It can be seen that by using this interlocking release device, the target and the wire rope can be reliably connected and disconnected in a narrow channel to ensure the smooth operation of online irradiation.

[0010] In some embodiments, the slide bar has a wedge protruding from its side; the locking assembly includes: a locking member that slidably engages with the sleeve to slide radially along the sleeve, the locking member being capable of forming a first wedge assembly with the slide bar in a sliding state; and a first elastic member connected to the locking member and the sleeve, the first elastic member causing the locking member to tend to slide closer to the slide bar.

[0011] In some embodiments, the sidewall of the sleeve is provided with a stepped groove extending radially along the sleeve, the stepped groove communicating with the inner cavity of the sleeve; the locking member is in the shape of a stepped rod and is adapted to the stepped groove, the locking member passing through the stepped groove.

[0012] In some embodiments, the first elastic element is a helical spring, which is located in one of the grooves of the stepped groove and sleeved on the locking element, with both ends of the helical spring connected to the sleeve and the locking element, respectively.

[0013] In some embodiments, the locking components are in multiple sets, and the multiple sets of locking components are distributed at circumferential intervals along the sleeve.

[0014] In some embodiments, the slide bar is further provided with a flange protruding from its side, the flange and the wedge being spaced apart axially in the slide bar; the unlocking member is sleeved on the slide bar and can slide between the flange and the wedge, the unlocking member and the locking member forming a second wedge assembly; the outer edge of the wedge is located inside the outer edge of the unlocking member; the locking member can pass over the unlocking member during the sliding of the slide bar relative to the sleeve.

[0015] In some embodiments, one end of the sleeve is open and the other end of the sleeve is closed; the closed end of the sleeve is provided with a first lifting ring, which is used to connect to the traction member.

[0016] In some embodiments, one end of the slide bar is provided with a second lifting ring, which is used to connect to the target component.

[0017] In some embodiments, the interlocking release device further includes a limiting component disposed inside the sleeve and located on the sliding path of the slide rod. The limiting component is configured to restrict the slide rod from sliding further into the sleeve after the slide rod has slid a second preset distance.

[0018] In some embodiments, the limiting component includes: a telescopic rod located inside the sleeve, one end of the telescopic rod being disposed in the sleeve, and the other end of the telescopic rod being positioned opposite the sliding rod; and a second elastic member disposed in the sleeve and connected to the telescopic rod, the second elastic member causing the telescopic rod to have an elongation tendency.

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figures 1 to 3As shown, the interlocking release device of this invention includes: a sleeve 100, a slide rod 200, a locking component 300, and an unlocking component 400; the sleeve 100 is used to connect with the traction component; the slide rod 200 is used to connect with the target component, and the slide rod 200 is used to slide in and out of the sleeve 100 along its own axis during sliding; the locking component 300 is disposed on the sleeve 100, and the locking component 300 can restrict the slide rod 200 from sliding out of the sleeve 100 after the slide rod 200 slides inward into the sleeve 100 by a first preset distance; the unlocking component 400 is disposed on the slide rod 200, and the unlocking component 400 can release the restriction of the locking component 300 on the slide rod 200 during the process of the slide rod 200 sliding inward into the sleeve 100 by a second preset distance and then sliding outward from the sleeve 100.

[0023] In the interlocking and disengaging device of this embodiment of the invention, the sleeve 100 and the slide rod 200 can be interlocked by the locking component 300 during the process of sliding towards each other. During the process of the sleeve 100 and the slide rod 200 continuing to slide towards each other and then away from each other, the unlocking component 400 can disengage the sleeve 100 and the slide rod 200.

[0024] In practical applications, the sleeve 100 is connected to a traction component, such as a wire rope, and the slide rod 200 is connected to a target component, such as a target. The sleeve 100 moves downward under its own weight and the combined action of the additional counterweight. When the sleeve 100 moves downward to the point where the slide rod 200 slides into the sleeve 100 a first preset distance, the locking component 300 is activated, making the sleeve 100 and the slide rod 200 interlocked. At this time, when the sleeve 100 is lifted, the slide rod 200 and the target will move upward synchronously with the sleeve 100. When it is necessary to disengage, the sleeve 100 is moved downward again. After the slide rod 200 slides into the sleeve 100 a second preset distance, the sleeve 100 is lifted. Under the action of the unlocking component 400, the sleeve 100 will separate from the slide rod 200.

[0025] It can be seen that by using this interlocking release device, the target and the wire rope can be reliably connected and disconnected in a narrow channel to ensure the smooth operation of online irradiation.

[0026] It should be noted here that when the sleeve 100 and the slide rod 200 are engaged or disengaged, the slide rod 200 is in a stationary state, specifically limited by a limiting structure. The limiting structure includes an annular platform and a truncated cone; the annular platform is formed on the inner wall of the narrow channel; the truncated cone is located on the connecting rope connecting the slide rod 200 and the target. It can be understood that the diameter of the truncated cone is larger than the inner diameter of the annular platform, so that after the truncated cone and the annular platform come into contact, the slide rod 200 cannot move downwards any further.

[0027] The following combination Figures 1 to 5 The structure and shape of the interlocking release device according to an embodiment of the present invention will be described in detail below: In some embodiments, reference is made to Figures 1 to 3The slide bar 200 is provided with a wedge portion 210 protruding from its side; the locking assembly 300 includes a locking member 310 and a first elastic member 320; the locking member 310 is slidably engaged with the sleeve 100 so as to slide radially along the sleeve 100, and the locking member 310 can form a first wedge assembly with the slide bar 200 in the sliding state; the first elastic member 320 is connected to the locking member 310 and the sleeve 100, and the first elastic member 320 causes the locking member 310 to have a tendency to slide towards the slide bar 200.

[0028] by Figure 3 For example, the side of the wedge 210 is an inclined surface, which slopes downwards away from the central axis of the slide rod 200. When interlocking is required, the sleeve 100 moves downwards under its own weight and the combined action of the additional counterweight, gradually fitting onto the slide rod 200. As the wedge 210 contacts the locking member 310, under the pressure of the inclined surface, the locking member 310 moves radially away from the slide rod 200 along the sleeve 100. After the wedge 210 passes the locking member 310, under the action of the first elastic member 320, the locking member 310 moves radially towards the slide rod 200 along the sleeve 100, contacting the bottom surface of the wedge 210, restricting the slide rod 200 from sliding downwards, and the sleeve 100 and the slide rod 200 are interlocked. With the above design, the sleeve 100 and the slide rod 200 can achieve reliable interlocking, and the operation is simple and quick.

[0029] In some embodiments, reference is made to Figure 2 and Figure 4 The sleeve 100 has a stepped groove 110 extending radially along the side wall of the sleeve 100, and the stepped groove 110 communicates with the inner cavity of the sleeve 100; the locking member 310 is in the shape of a stepped rod and is adapted to the stepped groove 110, and the locking member 310 passes through the stepped groove 110.

[0030] By cooperating with the stepped groove 110, the locking member 310 can slide radially along the sleeve 100. At the same time, the stepped groove 110 restricts the sliding distance of the locking member 310, which can prevent the locking member 310 from disengaging from the sleeve 100, so that the locking member 310 can be reused. That is, the sleeve 100 and the slide bar 200 can be repeatedly engaged and disengaged.

[0031] In some embodiments, reference is made to Figure 2 The first elastic element 320 is a helical spring, which is located in one of the grooves of the stepped groove 110 and is sleeved on the locking element 310. The two ends of the helical spring are respectively connected to the sleeve 100 and the locking element 310.

[0032] During the interlocking process, as the slide rod 200 slides into the sleeve 100, the wedge 210 opens the locking member 310, causing the locking member 310 to slide outward along the length direction of the stepped groove 110. During the outward sliding process, the locking member 310 compresses the coil spring. After the wedge 210 passes the locking member 310, under the action of the restoring force of the coil spring, the locking member 310 slides inward along the length direction of the stepped groove 110, preventing the slide rod 200 from sliding downward and disengaging from the sleeve 100.

[0033] The first elastic element 320 is a helical spring, which can undergo elastic deformation when compressed, effectively absorbing and storing energy. When the external force is removed, the helical spring can quickly release energy, causing the locking element 310 to slide, thereby restricting the sliding rod 200 from sliding outwards towards the sleeve 100.

[0034] Optionally, refer to Figure 2 and Figure 5 The locking components 300 are in multiple groups, and the multiple groups of locking components 300 are distributed at intervals along the circumference of the sleeve 100.

[0035] For example, there are six sets of locking components 300, which are evenly distributed around the axis of the sleeve 100. Correspondingly, there are also six sets of stepped grooves 110. The number of sets of locking components 300 can also be other, such as 4 sets, 5 sets, or 7 sets. Setting multiple sets of locking components 300 ensures the stability of the sleeve 100 and the slide bar 200 after they are interlocked.

[0036] In some embodiments, reference is made to Figure 2 and Figure 3 The slide bar 200 is also provided with a flange 220 protruding from its side. The flange 220 and the wedge portion 210 are spaced apart in the axial direction of the slide bar 200. The unlocking member 400 is sleeved on the slide bar 200 and can slide between the flange 220 and the wedge portion 210. The unlocking member 400 and the locking member 310 form a second wedge assembly. The outer edge of the wedge portion 210 is located inside the outer edge of the unlocking member 400. The locking member 310 can pass over the unlocking member 400 during the sliding of the slide bar 200 relative to the sleeve 100.

[0037] by Figure 2 For example, the unlocking member 400 is annular in shape and located between the flange 220 and the wedge 210. Its inner diameter is smaller than the outer edge dimensions of the flange 220 and the wedge 210, and an annular groove is formed between the flange 220 and the wedge 210. The outer surface of the unlocking member 400 is a slope, which is inclined from top to bottom towards the central axis of the unlocking member 400; the locking member 310 also has a slope at one end near the inner cavity of the sleeve 100, which is inclined from top to bottom towards the other end near the locking member 310.

[0038] refer to Figure 2 and Figure 3When disengagement is required, the sleeve 100 is moved downwards, and the locking member 310 gradually approaches the unlocking member 400. When the inclined surface of the locking member 310 contacts the unlocking member 400, under the compression of the unlocking member 400, the locking member 310 will slide outwards along the length direction of the stepped groove 110. After the locking member 310 passes the unlocking member 400, under the action of the first elastic member 320, the locking member 310 will slide inwards along the length direction of the stepped groove 110. At this time, the sleeve 100 is lifted, and the locking member 310 will contact the inclined surface of the unlocking member 400. The sleeve 100 moves upward, and the unlocking member 400 slides upward under the action of the locking member 310 until it contacts the bottom surface of the wedge 210. The sleeve 100 continues to move upward, and under the pressure of the inclined surface of the unlocking member 400, the locking member 310 slides outward again along the length of the stepped groove 110. Since the outer edge of the wedge 210 is located inside the outer edge of the unlocking member 400, the locking member 310 will pass over the unlocking member 400 and the wedge 210, and the sleeve 100 will be completely separated from the slide rod 200.

[0039] Optionally, refer to Figure 1 and Figure 2 One end of the sleeve 100 is open, and the other end is closed. The closed end of the sleeve 100 is provided with a first lifting ring 120, which is used to connect with a traction component. By providing the first lifting ring 120 at the closed end of the sleeve 100, the sleeve 100 can be connected with a traction component such as a wire rope. As the wire rope is retracted and released, the sleeve 100 moves upward and downward accordingly.

[0040] Optionally, continue to refer to Figure 1 and Figure 2 The bottom end of the slide bar 200 is provided with a second lifting ring 230, which is used to connect to the target part. The target part, such as the target, can be connected to the second lifting ring 230 via a connecting rope, thereby achieving connection with the slide bar 200. The slide bar 200 moves up or down with the sleeve 100, which correspondingly drives the target part to move up and down synchronously, thereby realizing the loading and unloading of the target part.

[0041] In some embodiments, reference is made to Figure 2 and Figure 3 The interlocking release device also includes a limiting component 500, which is located inside the sleeve 100 and on the sliding path of the slide rod 200. The limiting component 500 is configured to restrict the slide rod 200 from sliding further after it has slid into the sleeve 100 a second preset distance.

[0042] The limiting component 500 can limit the displacement of the slide rod 200 in the axial direction of the sleeve 100, and prevent the slide rod 200 from sliding excessively into the sleeve 100 during the disengagement process, which would cause the locking member 310 to cross the flange 220, thus ensuring that the sleeve 100 and the slide rod 200 can be disengaged smoothly.

[0043] In some embodiments, reference is made to Figure 2 The limiting component 500 includes: a telescopic rod 510 and a second elastic member 520; the telescopic rod 510 is located inside the sleeve 100, one end of the telescopic rod 510 is disposed in the sleeve 100, and the other end of the telescopic rod 510 is used to be opposite to the slide rod 200; the second elastic member 520 is disposed in the sleeve 100 and connected to the telescopic rod 510, and the second elastic member 520 causes the telescopic rod 510 to have a tendency to extend.

[0044] Continue to refer to Figure 2 The second elastic element 520 is a compression spring, which is sleeved on the telescopic rod 510. The upper end of the compression spring is connected to the top wall of the sleeve 100, and the lower end of the compression spring is connected to the telescopic rod 510. When disengagement is required, the sleeve 100 moves downward, and correspondingly, the slide rod 200 slides into the sleeve 100. When the locking element 310 passes the unlocking element 400, the slide rod 200 abuts against the bottom end of the telescopic rod 510. Under the restoring force of the compression spring, the telescopic rod 510 prevents the slide rod 200 from continuing to slide into the sleeve 100, that is, prevents the sleeve 100 from continuing to move downward. In this way, the locking element 310 is prevented from passing the unlocking element 400 and then passing the flange 220, ensuring that the sleeve 100 can move upward smoothly to complete the disengagement.

[0045] The working process of the interlocking release device in this embodiment of the invention is as follows: refer to Figures 1 to 3 The first lifting ring 120 is connected to the wire rope, and the second lifting ring 230 is connected to the second lifting ring 230 through the connecting rope. The wire rope is lowered, and the sleeve 100 moves downward under its own weight and the combined action of the additional counterweight, gradually fitting onto the slide rod 200. As the wedge 210 contacts the locking member 310, the multiple locking members 310 are opened under the pressure of the inclined surface of the wedge 210. After passing the wedge 210, under the action of the first elastic member 320, the multiple locking members 310 are inserted into the annular groove, and the sleeve 100 and the slide rod 200 are interlocked.

[0046] As described above, when disengagement is required, the sleeve 100 is moved downwards, and the locking member 310 gradually approaches the unlocking member 400. When the inclined surface of the locking member 310 contacts the unlocking member 400, multiple locking members 310 are opened again. After the locking member 310 passes the unlocking member 400, the sleeve 100 is lifted, and the locking member 310 will abut against the inclined surface of the unlocking member 400. As the sleeve 100 moves upwards, the unlocking member 400 slides upwards under the action of the locking member 310 until it contacts the bottom surface of the wedge portion 210. The sleeve 100 continues to move upwards, and under the pressure of the inclined surface of the unlocking member 400, multiple locking members 310 are opened again, passing over the unlocking member 400 and the wedge portion 210, and the sleeve 100 is completely separated from the slide rod 200.
