Description

Technical Field

[0001] The present application relates to the technical field of post-irradiation inspection, and in particular to a special hoist and a hoisting device for a target after irradiation. Background Art

[0002] When cutting the target after irradiation, we need to lift the irradiated target and put it vertically into the chuck to clamp it for cutting. This process is cumbersome, time-consuming, and has high risks in lifting. The current method of lifting the irradiated target is mainly: relying on the hot chamber crane to tie the irradiated target with a wire rope to lift it, and then the staff operates the master-slave manipulator outside the hot chamber to support the irradiated target and cooperate with the hot chamber crane to put it into the chuck and clamp it. The main disadvantages of this method are: 1. The lifting point position is not concentric with the irradiated target, and eccentric rotation will occur during the lifting process, affecting the concentricity of the irradiated target after it is placed in the chuck and the irradiated target after the chuck is clamped, which directly affects the accuracy of the cutting feed, and the entire installation and clamping process is cumbersome and time-consuming; 2. The risk of falling during the lifting process is very high. If conventional hoists are used to overcome the defects of non-concentricity and high risk of falling, the conventional hoists have complex structures and correspondingly complex internal force systems. If a fault or abnormality occurs, the cause is difficult to analyze, and due to the radiation environment, it is difficult to eliminate the fault or abnormality, thereby reducing the efficiency of the inspection test, and in severe cases, the test will be stagnant. Therefore, it is necessary to design a special hoist with a simple structure and easy fault / abnormality analysis to adapt to the hoisting work of the target in the radiation environment.

DETAILED DESCRIPTION

[0048] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0049] Example 1

[0050] See also Figure 1 and Figure 2 An embodiment of the present application provides a special hanger for a target after irradiation, and the special hanger for the target after irradiation includes a base 1, a first clamping member 2, a second clamping member 3 and a locking member 4.

[0051] The base 1 is used to connect the lifting equipment, and the specific shape and structure of the base 1 may not be limited; in actual implementation, considering the state stability of the base 1, the base 1 can be constructed as a rotating body, such as a commonly used cylinder, truncated cone, or even a saddle shape, so that the center of gravity of the base 1 is located on the rotation center line of the base 1, and the base 1 has a good degree of concentricity with the slings on the lifting equipment, which means that the base 1 is not prone to eccentric rotation after being lifted alone. The embodiment of the present application preferably constructs the base 1 into a cylindrical shape for easy processing and manufacturing, and easy to control manufacturing costs. In other embodiments, the base 1 can also be constructed as a non-rotating body with a uniform shape and a stable center of gravity after being lifted, such as a rectangular parallelepiped, a cube, a triangular pyramid, a polygonal pyramid, etc.

[0052] The first clamping member 2 is rotatably connected to the base 1, and the specific shape and structure of the first clamping member 2 may not be restricted as long as it can rotate freely on the base 1; in actual implementation, the first clamping member 2 may be constructed as a strip structure with a certain length, and one end of the first clamping member 2 in the length direction is rotatably connected to the base 1, so that the center of gravity of the first clamping member 2 is easily located below the rotational connection node between the first clamping member 2 and the base 1, which is beneficial to the rotation of the first clamping member 2.

[0053] The second clamping member 3 is rotatably connected to the base 1. The specific shape and structure of the second clamping member 3 is also not limited, as long as it can rotate freely on the base 1. The shape and structure of the second clamping member 3 and the first clamping member 2 can be the same or different. When the second clamping member 3 is the same as the first clamping member 2, the first clamping member 2 and the second clamping member 3 are symmetrically arranged on the base 1 so that the center of gravity of the two is located on the same vertical line as the center of gravity of the base 1 and the rotation states of the first clamping member 2 and the second clamping member 3 are basically consistent. When the second clamping member 3 and the first clamping member 2 are different, the center of gravity positions of the two can be adjusted by appropriately configuring the connection nodes between the two and the base 1; in actual implementation, the second clamping member 3 can also be constructed as a strip structure with a certain length, and one end of the second clamping member 3 in the length direction is rotatably connected to the base 1, so that the center of gravity of the second clamping member 3 is easily located below the rotation connection node between the second clamping member 3 and the base 1, which is beneficial to the rotation of the second clamping member 3.

[0054] A sliding hole is constructed on the locking piece 4, and the locking piece 4 is movably sleeved on the base 1 through the sliding hole, which means that the locking piece 4 can slide freely on the base 1 along the center line of the sliding hole, and the cross-sectional shape of the sliding hole can be unlimited, for example, it can be square, triangle, circle, ellipse, etc.; wherein, the locking piece 4 actually sleeves part of the base 1 in the sliding hole, for example, when the base 1 is a structure with the same cross-sectional profile such as a cylinder or a cuboid, the axial length of the base 1 is greater than the length of the sliding hole so that the locking piece 4 has a certain sliding stroke; for example, when the base 1 is a structure with different cross-sectional profiles such as a triangular pyramid, a polygonal pyramid, or a truncated cone, a column structure can be processed on the base 1 for the locking piece 4 to sleeve on, and the length of the column structure is greater than the length of the sliding hole so that the sliding hole has a certain sliding stroke. In actual implementation, considering the smoothness of the sliding of the locking member 4 on the base 1, the sliding hole on the locking member 4 can be constructed as a circular hole. When the cross-sectional profiles are different or the cross-sectional profile is non-circular, it is appropriate to process a cylindrical structure at one end on the base 1 for the locking member 4 to be sleeved, so that there is no sharp edge contact when the locking member 4 slides on the base 1, and the probability of being stuck is greatly reduced. Preferably, the base 1 is constructed as a cylinder to facilitate processing and manufacturing, and it is easy to obtain high manufacturing accuracy.

[0055] In the working state, the first clamping member 2 and the second clamping member 3 respectively rotate to the first position and the second position under the action of their own weight to be buckled on the hanging head of the irradiated target respectively, which means that after the sling is lifted, the first clamping member 2 can be kept in the first position and the second clamping member 3 can be kept in the second position in the natural state. The buckling of the hanging head of the irradiated target is realized in the process of the first clamping member 2 and the second clamping member 3 rotating to the first position and the second position respectively, so as to form a clamping effect on the hanging head of the irradiated target. Since the first clamping member 2 and the second clamping member 3 respectively form a buckling fit with the irradiated target, after the sling is lifted, the irradiated target can be lifted by the first clamping member 2 and the second clamping member 3. The locking member 4 moves to the third position under the action of its own weight. A locking ring 5 is provided on the locking member 4. When the locking member 4 is in the third position, the first clamping member 2 and the second clamping member 3 can be encircled in the locking ring 5 together. The locking member 4 forms a rotation limit for the first clamping member 2 and the second clamping member 3 through the locking ring 5.

[0056] When in use, after the sling is connected to the sling of the lifting equipment, the staff overcomes the gravity of the locking member 4 by the manipulator to make it slide upward on the base 1, and the locking member 4 can be separated from the third position. At this time, the rotation of the first clamping member 2 and the second clamping member 3 is not restricted. The first clamping member 2 and / or the second clamping member 3 are pushed apart by another manipulator to separate the first clamping member 2 and the second clamping member 3 from the first position and the second position respectively. The sling is moved to the top of the lifting head of the irradiated target by the lifting equipment and the first clamping member 2 and the second clamping member 3 are in the position. Correspondingly, the other manipulator is cancelled, so that the first clamping member 2 and the second clamping member 3 are rotated to the first position and the second position respectively under the action of their respective gravity, so that the first clamping member 2 and the second clamping member 3 can be buckled on the hanging head of the irradiated target respectively, and the manipulator is cancelled so that the locking member 4 slides downward on the base 1 under the action of its own gravity, so that the locking ring 5 on the locking member 4 can simultaneously encircle the first clamping member 2 and the second clamping member 3 therein to form a rotation restriction for the first clamping member 2 and the second clamping member 3, and the irradiated target is lifted by the lifting device. The locking member 4 is kept in the third position under the action of its own gravity, and if the first clamping member 2 and the second clamping member 3 have a tendency to rotate in the opposite direction, the first clamping member 2 and the second clamping member 3 will apply a force close to the horizontal direction after contacting the locking ring 5, and the vertical component of the force is extremely small, which will not force the locking member 4 to move in the direction against gravity, thereby ensuring that the irradiated target has good lifting stability. Of course, the first clamping member 2 and the second clamping member 3 can also be separated by shaking, which reduces the use of the robot and can verify the rotation smoothness of the first clamping member 2 and the second clamping member 3 at the same time.

[0057] The special hoist for irradiated targets provided in the embodiment of the present application replaces the existing process of irradiating targets through wire rope bolts, is easy to implement, and the state of the irradiated targets after being lifted depends on the connection / assembly accuracy of the hoist and the lifting equipment, and has high controllability, that is, after the irradiated targets are lifted, their lifting points are more concentric with the irradiated targets, and eccentric rotation is less likely to occur during the lifting process, which is beneficial to the subsequent positioning, clamping, etc. of the irradiated targets, thereby facilitating the improvement of inspection efficiency; and, the hoist clamps the targets through the first clamp 2 and the second clamp 3, and the risk of the targets falling after being lifted is smaller.

[0058] The embodiment of the present application provides a special hoist for irradiated targets, in which the clamping state of the first clamping member 2 and the second clamping member 3 is maintained by their own gravity, and at the same time, the locking member 4 is maintained at a third position based on its own gravity to achieve rotational limitation of the first clamping member 2 and the second clamping member 3, so that the clamping effect of the first clamping member 2 and the second clamping member 3 on the target is stable, and the risk of the target falling after being lifted is smaller. At the same time, the internal force system of the hoist is simple, the probability of failure / abnormality is small, and the cause of the failure / abnormality is easy to analyze, and the failure / abnormality is easier to eliminate.

[0059] In some optional embodiments, a slider can be provided on the locking member 4, and a corresponding slide groove can be provided on the base 1. The locking member 4 cooperates with the slide groove on the base 1 through the slider thereon, thereby realizing the sliding cooperation between the locking member 4 and the base 1. Compared with the method of movably sleeved the locking member 4 on the base 1 to realize the sliding cooperation, this structure has lower requirements for the base 1, that is, it is only necessary to open the corresponding slide groove on the base 1. Compared with the processing of the columnar body, the processing amount is relatively small.

[0060] When the locking member 4 forms a sliding fit with the base 1 through the structural form of the slider groove, the circumferential position of the locking member 4 relative to the base 1 is fixed, which means that after the base 1 is lifted, the locking member 4 cannot rotate around the vertical direction on the base 1. Therefore, the locking ring 5 may not be provided on the locking member 4. It is only necessary to ensure that after the locking member 4 is in the third position, part of the structure of the locking member 4 is located on the rotation path of the first clamping member 2 and / or the second clamping member 3.

[0061] In some optional embodiments, such as Figure 3 As shown, if the locking member 4 forms a sliding connection with the base 1 by a movable sleeve, the locking member 4 can be constructed as a cylindrical body. On the one hand, the cylindrical body structure is continuous, the structural strength is relatively good, and it is not easy to deform, and can form a good continuous restricting effect on the first clamping member 2 and the second clamping member 3. On the other hand, the cylindrical body has a relatively large weight. After the lifting device is lifted, the locking member 4 can be stably maintained in the third position, so that the positions of the first clamping member 2 and the second clamping member 3 are stably maintained.

[0062] In some optional embodiments, see Figure 2 or Figure 3 The locking member 4 is provided with a first operating portion 6 suitable for cooperation with a robot.

[0063] In the embodiment of the present application, the setting of the first operating part 6 is conducive to the staff to align the manipulator and the locking member 4, which can be conducive to improving the convenience of operation. For example, when the locking member 4 is constructed as a cylindrical cylinder, a boss can be set on the outer peripheral surface of the cylindrical cylinder, and the number of bosses can be set to two or more. The setting of the boss can facilitate the manipulator to achieve operations such as clamping and clamping. In actual implementation, the manipulator is usually set in a fixed position, and the base 1 may rotate to a certain extent after being lifted. During the lifting process, the locking member 4 may also rotate relative to the base 1, which means that the position of the boss is uncertain. Therefore, the boss can be constructed as an annular boss, which can avoid the process of operating the lifting equipment to adjust the position of the boss. Among them, the number of annular bosses can be one or more. When the number of annular bosses is multiple, they can be arranged at intervals along the axial direction of the locking member 4, which can improve the convenience of operation on the one hand, and achieve the weight gain of the locking member 4 on the other hand.

[0064] In some optional embodiments, see Figure 4 A second operating portion 7 suitable for cooperation with a robot is constructed on the base body 1.

[0065] In the embodiment of the present application, the provision of the second operating portion 7 on the base 1 can facilitate the manipulator to fix the base 1, that is, during the actual operation process, the sling is suspended in the air. When the locking member 4 is operated by the manipulator, the sling may move upward as a whole, which means that the overall state of the sling is unstable and the manipulator is needed to fix the overall state of the sling, that is, the manipulator needs to cooperate with the base 1. Therefore, through the provision of the second operating portion 7, it is convenient for the staff to use the manipulator to operate the base 1, thereby improving the convenience of operation.

[0066] In some optional embodiments, the second operating portion 7 is configured as a conical convex edge.

[0067] In the embodiment of the present application, configuring the second operating portion 7 as a conical convex edge can facilitate the relative positioning of the manipulator and the sling. For example, in an operating environment, the manipulator may be configured as a two-axis manipulator, which has two moving ends, and the two moving ends can move closer to or farther from each other to achieve clamping movement. When operating the locking member 4, first align one of the moving ends with the base 1, and then control the movement of the other moving end to drive the locking member 4 to slide on the base 1; one of the moving ends has a notch to avoid the sling on the lifting equipment. Based on the notch structure on the moving end, when aligning the base 1 with the moving end, the sling can be first inserted into the notch of the moving end, and then the moving end is moved down. Due to the guiding effect of the conical surface on the conical convex edge, when the moving end contacts the conical convex edge, the moving end can quickly form a center with the base 1.

[0068] In some optional embodiments, see Figure 5 The first clamping member 2 may specifically include a first connecting portion 21 and a first clamping portion 22. The first connecting portion 21 and the first clamping portion 22 may be connected together by, for example, welding, bolts, or snaps. Since the first clamping member 2 in the embodiment of the present application is used in a lifting environment, in order to reduce the manufacturing cost, the first connecting portion 21 and the first clamping portion 22 may be designed as an integrally formed structure; the first connecting portion 21 may be rotatably connected to the base 1 by a pin, a pin shaft, etc., which means that a rotating hole is configured on the first connecting portion 21; and a first limiting The first clamping groove 24 is adapted to cooperate with the target after irradiation, wherein the first clamping groove 24 can avoid the hanging head structure on the target after irradiation, that is, when the hanging head on the target after irradiation is located in the first clamping groove 24, the side groove wall of the first clamping groove 24 can be buckled with the hanging head of the target after irradiation; in the working state, the locking member 4 can collide with the first limiting boss 23 when it moves under its own gravity to keep the locking member 4 in the third position, that is, the first limiting boss 23 can limit the continuous sliding of the locking member 4 in the working state. In other embodiments, the first limiting boss 23 may not be provided on the first clamping portion 22, but a limiting boss is provided on the base 1, and a corresponding limiting ring is provided on the hole wall of the sliding hole on the locking member 4, and the locking member 4 is limited to continue to slide down by the limiting boss and the limiting ring.

[0069] In some optional embodiments, when the locking member 4 is constructed as a cylindrical body, an arcuate surface adapted to the inner hole of the locking hole can be constructed on the first connecting portion 21, thereby reducing the possibility of sharp edge contact between the locking member 4 and the first clamping member 2, preventing the locking member 4 from being stuck on the first clamping member 2, and ensuring the smooth sliding of the locking member 4.

[0070] In some optional embodiments, see Figure 6The second clamping member 3 may specifically include a second connecting portion 31 and a second clamping portion 32. The second connecting portion 31 and the second clamping portion 32 may be connected together by, for example, welding, bolts, or snaps. Since the second clamping member 3 in the embodiment of the present application is used in a lifting environment, in order to reduce the manufacturing cost, the second connecting portion 31 and the second clamping portion 32 may be designed as an integrally formed structure; the second connecting portion 31 may be rotatably connected to the base 1 by a pin, a pin shaft, etc., which means that a rotating hole is configured on the second connecting portion 31; a second limiting boss 33 and a second clamping groove 34 suitable for cooperating with the irradiated target are configured on the second clamping portion 32, wherein the second clamping groove 34 may be configured to hold the hanging head structure on the irradiated target The structure forms an avoidance, that is, when the hanging head on the target after irradiation is located in the second clamping groove 34, the side groove wall of the second clamping groove 34 can be buckled with the hanging head of the target after irradiation, wherein the first clamping groove 24 and the second clamping groove 34 form a clamping cavity together, that is, when the first clamping member 2 and the second clamping member 3 are respectively located in the first position and the second position, the first clamping groove 24 and the second clamping groove 34 can form a clamping cavity whose shape is adapted to the hanging head of the target after irradiation; in the working state, when the locking member 4 moves under the action of its own gravity, it can contact with the second limiting boss 33 to keep the locking member 4 in the third position, that is, in the working state, the second limiting boss 33 can limit the locking member 4 from continuously sliding down. In other embodiments, the second limiting boss 33 may not be provided on the second clamping portion 32, but a limiting boss is provided on the base 1, and a corresponding limiting ring is provided on the hole wall of the sliding hole on the locking member 4, and the locking member 4 is limited from continuously sliding down by the limiting boss and the limiting ring.

[0071] In some optional embodiments, when the locking member 4 is constructed as a cylindrical body, an arc surface that is adapted to the inner hole of the locking hole can be constructed on the second connecting portion 31. This can reduce the possibility of sharp edge contact between the locking member 4 and the second clamping member 3, prevent the locking member 4 from being stuck on the second clamping member 3, and ensure the smooth sliding of the locking member 4.

[0072] In some optional embodiments, the first clamp 2 and the second clamp 3 can be arranged at intervals or adjacent to each other. The adjacent arrangement means that in the working state, the first clamp 2 and the second clamp 3 are in contact with each other when they are in the first position and the second position. When the first clamp 2 and the second clamp 3 are arranged adjacent to each other, the first connecting portion 21 and the second connecting portion 31 can be constructed as a semi-cylindrical shape, which means that when the first clamp 2 and the second clamp 3 are in the first position and the second position, the first connecting portion 21 and the second connecting portion 31 can form a cylinder. In this way, the first clamp 2 and the second clamp 3 are equivalent to forming a rotation limit with each other. When the first clamp 2 and the second clamp 3 are in a free state, they can be more quickly stabilized in the first position and the second position under the action of gravity.

[0073] In some optional embodiments, in the working state, the rotation connection node between the first clamping member 2 and the base 1 is located between the center of gravity of the first clamping member 2 and the second clamping member 3 .

[0074] In the embodiment of the present application, after the hoist is lifted, due to the setting of the center of gravity position of the first clamping member 2, the first clamping member 2 can be closely abutted against the second clamping member 3, which is beneficial to maintaining the state of the first clamping member 2. At the same time, in this state, the first clamping member 2 is not easy to rotate in the opposite direction. When lifting the irradiated target, the first clamping member 2 is not easy to slide relative to the lifting head on the irradiated target, thereby ensuring the lifting stability.

[0075] In some optional embodiments, in the working state, the rotation connection node between the second clamping member 3 and the base 1 is located between the center of gravity of the second clamping member 3 and the first clamping member 2 .

[0076] In the embodiment of the present application, after the hoist is lifted, due to the setting of the center of gravity position of the first clamping member 2, the first clamping member 2 and the second clamping member 3 can be close to each other, which is beneficial to maintaining the state of the first clamping member 2 and the second clamping member 3. At the same time, in this state, the second clamping member 3 is not easy to rotate in the opposite direction. When lifting the irradiated target, the second clamping member 3 is not easy to slide relative to the lifting head on the irradiated target, thereby ensuring the lifting stability.

[0077] In some optional embodiments, the base body 1 is configured with threaded holes suitable for connecting a lifting device.

[0078] In an embodiment of the present application, the threaded hole can form a threaded fit with a stud or a bolt. For example, the stud can be fixedly connected to the sling of the lifting equipment. The sling is connected to the base 1 through the stud. The threaded fit has good coaxiality, thereby ensuring the concentricity of the sling and the base 1 and reducing the probability of eccentric rotation of the base 1.

[0079] Example 2

[0080] like Figure 7 As shown, an embodiment of the present application provides a special hanger for a target after irradiation, and the special hanger for a target after irradiation includes a base 1, a first clamping member 2, a second clamping member 3 and a locking member 4.

[0081] The base 1 is used to connect the lifting equipment, and the specific shape and structure of the base 1 may not be limited; in actual implementation, considering the state stability of the base 1, the base 1 can be constructed as a rotating body, such as a commonly used cylinder, truncated cone, or even a saddle shape, so that the center of gravity of the base 1 is located on the rotation center line of the base 1, and the base 1 has a good degree of concentricity with the slings on the lifting equipment, which means that the base 1 is not prone to eccentric rotation after being lifted alone. The embodiment of the present application preferably constructs the base 1 into a cylindrical shape for easy processing and manufacturing, and easy to control manufacturing costs. In other embodiments, the base 1 can also be constructed as a non-rotating body with a uniform shape and a stable center of gravity after being lifted, such as a rectangular parallelepiped, a cube, a triangular pyramid, a polygonal pyramid, etc.

[0082] The first clamping member 2 is rotatably connected to the base 1, and the specific shape and structure of the first clamping member 2 may not be restricted as long as it can rotate freely on the base 1; in actual implementation, the first clamping member 2 may be constructed as a strip structure with a certain length, and one end of the first clamping member 2 in the length direction is rotatably connected to the base 1, so that the center of gravity of the first clamping member 2 is easily located below the rotatable connection node between the first clamping member 2 and the base 1, which is beneficial to the rotation of the first clamping member 2; a first pin hole 25 is constructed on the first clamping member 2.

[0083] The second clamping member 3 is rotatably connected to the base 1. The specific shape and structure of the second clamping member 3 are also not limited, as long as it can rotate freely on the base 1. The shape and structure of the second clamping member 3 and the first clamping member 2 can be the same or different. When the second clamping member 3 is the same as the first clamping member 2, the first clamping member 2 and the second clamping member 3 are symmetrically arranged on the base 1 so that the center of gravity of the two is located on the same vertical line as the center of gravity of the base 1 and the rotation state of the first clamping member 2 and the second clamping member 3 is basically consistent. When the second clamping member 3 and the first clamping member 2 are different, the center of gravity of the two can be adjusted by properly configuring the connection nodes between the two and the base 1. In actual implementation, the second clamping member 3 can also be constructed as a strip structure with a certain length, and one end of the second clamping member 3 in the length direction is rotatably connected to the base 1, so that the center of gravity of the second clamping member 3 is easily located below the rotation connection node between the second clamping member 3 and the base 1, which is conducive to the rotation of the second clamping member 3. The second clamping member 3 is configured with a second pin hole 35.

[0084] A sliding hole is constructed on the locking piece 4, and the locking piece 4 is movably sleeved on the base 1 through the sliding hole, which means that the locking piece 4 can slide freely on the base 1 along the center line of the sliding hole, and the cross-sectional shape of the sliding hole can be unlimited, for example, it can be square, triangle, circle, ellipse, etc.; wherein, the locking piece 4 actually sleeves part of the base 1 in the sliding hole, for example, when the base 1 is a structure with the same cross-sectional profile such as a cylinder or a cuboid, the axial length of the base 1 is greater than the length of the sliding hole so that the locking piece 4 has a certain sliding stroke; for example, when the base 1 is a structure with different cross-sectional profiles such as a triangular pyramid, a polygonal pyramid, or a truncated cone, a column structure can be processed on the base 1 for the locking piece 4 to sleeve on, and the length of the column structure is greater than the length of the sliding hole so that the sliding hole has a certain sliding stroke. In actual implementation, considering the smoothness of the sliding of the locking member 4 on the base 1, the sliding hole on the locking member 4 can be constructed as a circular hole. When the cross-sectional profiles are different or the cross-sectional profiles are non-circular, it is appropriate to process a cylindrical structure at one end on the base 1 for the locking member 4 to be sleeved, so that there is no sharp edge contact when the locking member 4 slides on the base 1, and the probability of being stuck is greatly reduced. Preferably, the base 1 is constructed as a cylinder to facilitate processing and manufacturing, and it is easy to obtain a higher manufacturing accuracy. The locking member 4 is provided with a latch 8, which can be inserted into the first latch hole 25 or the second latch hole 35.

[0085] In the working state, the first clamping member 2 and the second clamping member 3 respectively rotate to the first position and the second position under the action of their own weight to be respectively buckled on the hanging head of the irradiated target, which means that after the sling is lifted, the first clamping member 2 can be maintained in the first position and the second clamping member 3 can be maintained in the second position in the natural state. The buckling of the hanging head of the irradiated target is realized in the process of the first clamping member 2 and the second clamping member 3 rotating to the first position and the second position respectively, thereby forming a clamping effect on the hanging head of the irradiated target. Since the first clamping member 2 and the second clamping member 3 respectively form a buckling fit with the irradiated target, after the sling is lifted, the irradiated target can be lifted by the first clamping member 2 and the second clamping member 3, and the axes of the first latch hole 25 and the second latch hole 35 coincide with the vertical direction. The locking member 4 moves to the third position under the action of its own weight, and the latch 8 on the locking member 4 is inserted into the first latch hole 25 and the second latch hole 35 to form a rotation limit for the first clamping member 2 and the second clamping member 3.

[0086] When in use, after the sling is connected to the sling of the lifting equipment, the staff overcomes the gravity of the locking member 4 by the manipulator to make it slide upward on the base 1, and the locking member 4 can be separated from the third position. At this time, the rotation of the first clamping member 2 and the second clamping member 3 is not restricted. The first clamping member 2 and / or the second clamping member 3 are pushed apart by another manipulator to separate the first clamping member 2 and the second clamping member 3 from the first position and the second position respectively. The sling is moved to the top of the lifting head of the irradiated target by the lifting equipment so that the positions of the first clamping member 2 and the second clamping member 3 correspond to each other, and the other manipulator is cancelled so that the first clamping member 2 and the second clamping member 3 are separated. The holder 3 rotates to the first position and the second position respectively under the action of their own gravity, so that the first clamping member 2 and the second clamping member 3 can be buckled on the hanging head of the irradiated target respectively, and the position of the locking member 4 is adjusted by the manipulator so that the two latches 8 on the locking member 4 correspond to the positions of the first latch hole 25 and the second latch hole 35 respectively, and the manipulator is withdrawn to make the locking member 4 slide downward on the base 1 under the action of its own gravity, so that the latches 8 on the locking member 4 can be inserted into the first latch hole 25 and the second latch hole 35 at the same time to form a rotation restriction for the first clamping member 2 and the second clamping member 3, and the irradiated target is hoisted by the hoisting equipment. The locking member 4 is kept in the third position under the action of its own gravity, and if the first clamping member 2 and the second clamping member 3 have a tendency to rotate in the opposite direction, the first clamping member 2 and the second clamping member 3 will apply a force close to the horizontal direction to the latch 8, and the vertical component of the force is extremely small, which will not force the locking member 4 to move in the direction against gravity, thereby ensuring that the irradiated target has good hoisting stability. Of course, the first clamping member 2 and the second clamping member 3 can also be separated by shaking, which reduces the use of the robot and can verify the rotation smoothness of the first clamping member 2 and the second clamping member 3 at the same time.

[0087] In some optional embodiments, a slide groove may be constructed on the base 1 and a slider may be provided on the locking member 4, and the locking member 4 cooperates with the slide groove through the slider to achieve sliding cooperation between the locking member 4 and the base 1. When the base 1 is lifted, the locking member 4 will not rotate vertically, so that the latch 8 on the locking member 4 can automatically correspond to the first latch hole 25 and the second latch hole 35, eliminating the need for adjusting the position of the locking member 4.

[0088] In some optional embodiments, the number of the first latch hole 25 and the number of the second latch hole 35 can be configured to be multiple.

[0089] Example 3

[0090] like Figure 8 As shown, an embodiment of the present application provides a special hanger for a target after irradiation, and the special hanger for a target after irradiation includes a base 1, a first clamping member 2, a second clamping member 3 and a locking member 4.

[0091] The base 1 is used to connect the lifting equipment, and the specific shape and structure of the base 1 may not be limited; in actual implementation, considering the state stability of the base 1, the base 1 can be constructed as a rotating body, such as a commonly used cylinder, truncated cone, or even a saddle shape, so that the center of gravity of the base 1 is located on the rotation center line of the base 1, and the base 1 has a good degree of concentricity with the slings on the lifting equipment, which means that the base 1 is not prone to eccentric rotation after being lifted alone. The embodiment of the present application preferably constructs the base 1 into a cylindrical shape for easy processing and manufacturing, and easy to control manufacturing costs. In other embodiments, the base 1 can also be constructed as a non-rotating body with a uniform shape and a stable center of gravity after being lifted, such as a rectangular parallelepiped, a cube, a triangular pyramid, a polygonal pyramid, etc.

[0092] The first clamping member 2 is rotatably connected to the base 1, and the specific shape and structure of the first clamping member 2 may not be restricted as long as it can rotate freely on the base 1; in actual implementation, the first clamping member 2 may be constructed as a strip structure with a certain length, and one end of the first clamping member 2 in the length direction is rotatably connected to the base 1, so that the center of gravity of the first clamping member 2 is easily located below the rotational connection node between the first clamping member 2 and the base 1, which is beneficial to the rotation of the first clamping member 2.

[0093] The second clamping member 3 is rotatably connected to the base 1. The specific shape and structure of the second clamping member 3 is also not limited, as long as it can rotate freely on the base 1. The shape and structure of the second clamping member 3 and the first clamping member 2 can be the same or different. When the second clamping member 3 is the same as the first clamping member 2, the first clamping member 2 and the second clamping member 3 are symmetrically arranged on the base 1 so that the center of gravity of the two is located on the same vertical line as the center of gravity of the base 1 and the rotation states of the first clamping member 2 and the second clamping member 3 are basically consistent. When the second clamping member 3 and the first clamping member 2 are different, the center of gravity positions of the two can be adjusted by appropriately configuring the connection nodes between the two and the base 1; in actual implementation, the second clamping member 3 can also be constructed as a strip structure with a certain length, and one end of the second clamping member 3 in the length direction is rotatably connected to the base 1, so that the center of gravity of the second clamping member 3 is easily located below the rotation connection node between the second clamping member 3 and the base 1, which is beneficial to the rotation of the second clamping member 3.

[0094] The locking member 4 is rotatably connected to the base 1 , the number of the locking members 4 can be configured as two, and the locking member 4 can be specifically constructed as a strip structure, one end of the locking member 4 is rotatably connected to the base 1 , and the other end is in a free state.

[0095] In the working state, the first clamping member 2 and the second clamping member 3 respectively rotate to the first position and the second position under the action of their own weight to be respectively buckled on the hanging head of the irradiated target, which means that after the sling is lifted, the first clamping member 2 can be maintained in the first position and the second clamping member 3 can be maintained in the second position in the natural state. The buckling of the hanging head of the irradiated target is realized in the process of the first clamping member 2 and the second clamping member 3 rotating to the first position and the second position respectively, thereby forming a clamping effect on the hanging head of the irradiated target. Since the first clamping member 2 and the second clamping member 3 respectively form a buckling fit with the irradiated target, after the sling is lifted, the irradiated target can be lifted by the first clamping member 2 and the second clamping member 3. The locking member 4 moves to the third position under the action of its own weight, and the other end of the locking member 4 is located in the rotation direction of the first clamping member 2 or the second clamping member 3 to form a rotation limit for the first clamping member 2 and the second clamping member 3.

[0096] When in use, after the sling is connected to the sling of the lifting equipment, the staff overcomes the gravity of the locking piece 4 by the manipulator to make it rotate on the base 1, and the locking piece 4 can be separated from the third position, which means that the other end of the locking piece 4 is separated from the rotation path of the first clamping piece 2 and the second clamping piece 3. At this time, the rotation of the first clamping piece 2 and the second clamping piece 3 is not restricted. The first clamping piece 2 and / or the second clamping piece 3 are pushed apart by another manipulator to make the first clamping piece 2 and the second clamping piece 3 separate from the first position and the second position respectively. The sling is moved to the top of the lifting head of the irradiated target by the lifting equipment so that the first clamping piece 2 and the second clamping piece 3 are in corresponding positions, and the other manipulator is canceled. A manipulator is provided to enable the first clamping member 2 and the second clamping member 3 to rotate to the first position and the second position respectively under the action of their respective gravity, so that the first clamping member 2 and the second clamping member 3 can be respectively buckled on the hanging head of the irradiated target, and the position of the locking member 4 is adjusted by the manipulator so that the two latches 8 on the locking member 4 correspond to the positions of the first latch hole 25 and the second latch hole 35 respectively, and the manipulator is withdrawn to allow the locking member 4 to rotate freely under the action of its own gravity, so that the other end of the locking member 4 can be re-positioned on the rotation path of the first clamping member 2 and the second clamping member 3 to form a rotation restriction on the first clamping member 2 and the second clamping member 3, and the irradiated target is lifted by the lifting equipment. The locking member 4 is kept in the third position under the action of its own gravity, and if the first clamping member 2 and the second clamping member 3 have a tendency to rotate in the opposite direction, the first clamping member 2 and the second clamping member 3 will apply a force close to the horizontal direction to the other end of the locking member 4, and the vertical component of the force is very small, which will not force the locking member 4 to rotate in the direction against gravity, thereby ensuring that the target has good hoisting stability after irradiation. Of course, the first clamping member 2 and the second clamping member 3 can also be separated by shaking, reducing the use of the manipulator, and at the same time, the smoothness of the rotation of the first clamping member 2 and the second clamping member 3 can be verified.

[0097] In some optional embodiments, a blocking protrusion may be provided on the base 1 to limit the rotation of the locking member 4 in one direction so that the locking member 4 can be quickly stabilized in the third position.

[0098] In some optional embodiments, a blocking surface is constructed on the locking member 4, and a contact working surface is constructed on the first clamping member 2 and the second clamping member 3 respectively, and the area of ​​the contact working surface is larger than the area of ​​the blocking surface. Therefore, during the lifting process, if the locking member 4 shakes slightly due to vibration, it can still form a rotation limit for the first clamping member 2 and the second clamping member 3.

[0101] Finally, it should be noted that the difference between Example 2 and Example 3 and Example 1 lies in the connection method between the locking member 4 and the base 1 or the matching method between the locking member 4 and the first clamping member 2 and the second clamping member 3.
