DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] refer to Figure 1 and Figure 2 The embodiment provides a lifting device for detecting nuclear waste barrel sampling, which is set on one side of the detection platform 1 and includes a support frame 2, on which a swingable support beam 3 is provided, a winding wheel 4 is installed at the top of the support beam 3, a sling 5 is wound around the winding wheel 4, a clamp 6 is connected to the bottom of the sling 5, and an anti-deviation mechanism 7 is provided between the sling 5 and the support beam 3, wherein the top of the support beam 3 has a first position located outside the detection platform 1 and a second position located just above the center of the detection platform 1, and the first position and the second position are symmetrically distributed on both sides of the rotation center of the bottom end of the support beam 3; refer to Figures 1 to 3 , Figure 8The anti-deflection mechanism 7 includes an upper sleeve 7.1, a lower sleeve 7.2 and an anti-deflection plate 7.3. The upper sleeve 7.1 is rotatably mounted on the support beam 3, and the rotation center of the upper sleeve 7.1 coincides with the axis of the winding wheel 4. The lower sleeve 7.2 is fixedly mounted on the top of the clamp 6, and the upper sleeve 7.1 and the lower sleeve 7.2 are both sleeved on the outside of the sling 5. A correction cavity 7.4 for inserting the bottom end of the upper sleeve 7.1 is provided in the lower sleeve 7.2. An anti-deflection plate 7.3 is provided between two same side surfaces of the support beam 3. When the support beam 3 is in the first position and the second position, the upper sleeve 7.1 contacts with the two anti-deflection plates 7.3 respectively, and the sling 5 is in a vertical state.

[0021] The hoisting device used for sampling nuclear waste barrels can realize the adjustment of the position of the nuclear waste barrel on the outside and inside of the detection platform 1 by switching the support beam 3 between the first position and the second position, and then realize the lifting and lowering of the nuclear waste barrel by combining the winding and releasing of the sling 5 by the winding wheel 4. In this way, the loading and unloading operation of the nuclear waste barrel on the detection platform 1 can be realized. The clamp 6 is arranged at the bottom end of the sling 5, and is used to clamp or release the nuclear waste barrel.

[0022] refer to Figure 1 , Figure 4 and Figure 5 When the upper sleeve 7.1 and the lower sleeve 7.2 are separated, the upper sleeve 7.1 is respectively supported on the two anti-deflection plates 7.3, and the support beam 3 is in an inclined state. Then, the upper sleeve 7.1 can limit the sling 5 by using the eccentric force in combination with the blocking effect of the anti-deflection plates 7.3, so as to better keep the sling 5 in a vertical state. Then, when the top end of the support beam 3 is located at the first position, shaking is prevented during the lifting of the nuclear waste barrel, thereby improving the hoisting stability and safety of the nuclear waste barrel.

[0023] refer to Fig. 9 and Fig.10 When the lower sleeve 7.2 is sleeved outside the upper sleeve 7.1, the upper sleeve 7.1, the lower sleeve 7.2 and the clamp 6 form an extremely stable whole. Furthermore, when the top of the support beam 3 is in the second position, the stability of the nuclear waste barrel is stronger. At the same time, when the nuclear waste barrel is lowered onto the detection platform 1, the nuclear waste barrel can be directly prevented from being placed at the center of the detection platform 1 more accurately.

[0024] refer to Figure 3A support column 8 is arranged between the top ends of the two support beams 3, the reel 4 is rotatably mounted on the support column 8, and the top end of the upper sleeve 7.1 is rotatably sleeved on the support column 8 through the suspension 9. When the support beam 3 switches between the first position and the second position in the state of hoisting the nuclear waste barrel, the top end of the suspension 9 rotates outside the support column 8, and combined with the gravity, the upper sleeve 7.1 is always in a vertical state. Furthermore, the upper sleeve 7.1 is used to limit and stabilize the sling 5, improve the stability and safety when hoisting the nuclear waste barrel, and prevent the nuclear waste barrel from shaking.

[0025] refer to Figure 3 The anti-deflection mechanism 7 also includes a damping plate 7.5 fixedly mounted on the support beam 3, and a plurality of arc-shaped damping grooves 7.6 are equidistantly provided on the circumferential surface of the damping plate 7.5. A damping rod 7.7 is arranged in the damping groove 7.6, and an elastic telescopic rod 7.8 is connected to the end of the damping rod 7.7, and the elastic telescopic rod 7.8 is installed on the suspension 9.

[0026] During the rotation of the suspension 9 outside the support column 8, the damping rod 7.7 passes through the damping grooves 7.6 one by one in sequence. By utilizing the elastic force of the elastic telescopic rod 7.8, the elastic telescopic rod 7.8 will be stretched during the process of the damping rod 7.7 leaving any damping groove 7.6. At this time, the reaction force can reduce the rotation speed of the suspension 9 outside the support column 8, and apply a damping effect to the rotation of the suspension 9. Such an arrangement can reduce the kinetic energy and inertia force of the nuclear waste barrel, further reduce the degree of shaking of the nuclear waste barrel, and improve the stability and safety of hoisting the nuclear waste barrel.

[0027] refer to Fig.10 The inner bottom wall of the damping groove 7.6 is provided with a strip-shaped locking groove 7.9 toward the center of the damping disk 7.5. The width of the locking groove 7.9 is set to match the outer diameter of the damping rod 7.7. The elastic telescopic rod 7.8 is slidably installed on the suspension 9 in the height direction, and the bottom end of the elastic telescopic rod 7.8 extends to the bottom of the suspension 9. When the lower sleeve 7.2 is upwardly sleeved to the highest position of the upper sleeve 7.1, the top end of the lower sleeve 7.2 lifts the elastic telescopic rod 7.8 to make the damping rod 7.7 move from the locking groove 7.9 to the damping groove 7.6.

[0028] refer to Figure 4 , Figure 5 and Figure 7In the initial state, the elastic telescopic rod 7.8 is located at the lowest position on the suspension 9 under the action of gravity, and the bottom end of the elastic telescopic rod 7.8 is in a state of extending below the suspension 9, and the damping rod 7.7 is located in the locking groove 7.9. At this time, the suspension 9 is locked on the support column 8. Furthermore, when the top end of the support beam 3 is in the first position and the second position, the suspension 9 and the upper sleeve 7.1 are both locked, and the upper sleeve 7.1 is in a vertical downward state, so that in the process of lifting and lowering the nuclear waste barrel, the sling 5 is limited by the upper sleeve 7.1, so that the nuclear waste barrel can be lifted and lowered stably, the stability of lifting and lowering the nuclear waste barrel is improved, and the lowering accuracy of the nuclear waste barrel is improved.

[0029] refer to Fig. 9 and Fig.10 , the top end of the support beam 3 is in the second position, and when the nuclear waste barrel is placed on the detection platform 1, the bottom end of the upper sleeve 7.1 is located in the deviation correction cavity 7.4. This arrangement allows the nuclear waste barrel to be stably limited in the process of lowering the nuclear waste barrel onto the detection platform 1, ensuring that the nuclear waste barrel is vertically lowered to the center position of the detection platform 1, and fully ensuring the lowering accuracy of the nuclear waste barrel. Similarly, in the process of lifting the nuclear waste barrel on the detection platform 1, the clamp 6 is effectively limited and stably moves up and down in the vertical direction, making it easier for the clamp 6 to accurately clamp the nuclear waste barrel. In addition, by limiting the vertical lifting movement of the nuclear waste barrel during the process of lifting the nuclear waste barrel on the detection platform 1, it also has the function of preventing the nuclear waste barrel from colliding with the detection platform 1.

[0030] refer to Figure 7 and Figure 8 The bottom end of the upper sleeve 7.1 is configured to be a conical structure, the top end of the deviation correction cavity 7.4 is configured to be an outwardly expanded trumpet shape, and when the lower sleeve 7.2 is sleeved to the highest position of the upper sleeve 7.1, the upper end surface of the lower sleeve 7.2 contacts the bottom surface of the anti-deflection plate 7.3. By such a configuration, the lower sleeve 7.2 can be sleeved on the upper sleeve 7.1 more stably.

[0031] refer to Figure 6 The clamp 6 includes a main body part 6.1, a bracket part 6.2, a clamping rod 6.3 and an electric telescopic rod 6.4. The main body part 6.1 is fixedly connected to the bottom end of the lower sleeve 7.2. The bottom end of the sling 5 passes through the lower sleeve 7.2 and is fixedly connected to the top of the main body part 6.1. The bracket part 6.2 is a scissor-type structure. The bracket part 6.2 is installed on the main body part 6.1. The electric telescopic rod 6.4 is installed in the main body part 6.1. The protruding end of the electric telescopic rod 6.4 is connected to the top of the bracket part 6.2. A clamping rod 6.3 is set at both ends of the bottom of the bracket part 6.2. The clamping rod 6.3 is set to an arc rod that matches the outer circumference of the nuclear waste barrel.

[0032] The extended end of the electric telescopic rod 6.4 moves upward or downward on the main body 6.1 by driving the top end of the bracket part 6.2, and controls the two clamping rods 6.3 to clamp or release the nuclear waste barrel from both sides of the nuclear waste barrel.

[0033] A bracket part 6.2 is arranged on both sides of the main body part 6.1, and an upper inflection point and a lower inflection point are arranged in the middle of the bracket part 6.2, an upper support 6.5 is rotatably connected between the two upper inflection points, and a lower support 6.6 is rotatably connected between the two lower inflection points. The upper support 6.5 is slidably installed on the main body part 6.1 in the height direction, the protruding end of the electric telescopic rod 6.4 is connected to the top of the upper support 6.5, and the lower support 6.6 is fixedly installed on the main body part 6.1.

[0034] refer to Figure 2 The reel 4 is rotatably mounted on the support beam 3, and the reel 4 is connected to a rotary motor 10, and the rotary motor 10 is fixedly mounted on the top of the support beam 3. The reel 4 can be controlled to wind or release the sling 5 by the forward and reverse rotation of the rotary motor 10, so as to realize the lifting and lowering operation of the nuclear waste barrel.

[0035] refer to Figure 4 The bottom end of the support beam 3 is rotatably mounted on the support frame 2, and a driving cylinder 11 is mounted on the support frame 2. The bottom end of the driving cylinder 11 is rotatably connected to the support frame 2, and the top end of the driving cylinder 11 is rotatably connected to the support beam 3. By extending or retracting the extended end of the driving cylinder 11, the top end of the support beam 3 can be driven to switch between the first position and the second position.
