Description

Technical Field

[0001] The utility model relates to the technical field of steel drum lifting, in particular to a 200L standard steel drum lifting mechanism for a nuclear power plant. Background Art

[0002] The 200L standard steel drum lifting mechanism is mainly used for sorting and barreling contaminated waste in nuclear power plants. To ensure that the 200L steel drum is delivered to the right place, the drum is lifted to the sealing port of the sorting area through the drum lifting device, and the sealing ring is compressed to keep the 200L steel drum at a certain height and in a sealed state. The 200L standard steel drum lifting mechanism is used to lift the 200L drum to dock with the sorting hole in the sorting area. It is set directly below the sorting hole and installed in the middle of the transmission roller. The lifting mechanism uses a chain drive to drive the eccentric shaft to rotate, driving the lifting table to rise or fall. When lifting, dock the 200L drum with the sorting hole, and when descending, the 200L drum falls to the lateral transmission mechanism. When the equipment is powered on, the sprocket installed on the drive motor rotates, and the two eccentric wheel groups on the upper part are driven to rotate through the chain. The contact point between the flat bar at the bottom of the lifting platform and the cam rises or falls with the rotation of the cam, causing the lifting platform to rise or fall. In order to ensure that the effective lifting range is controllable, the detection unit is designed with two sets of sensors, one for low-position detection and one for high-position detection. When in use, the lifting range can be adjusted according to actual needs. The 200L standard steel barrel has a certain height. When it is placed on the lifting platform, as the lifting platform moves up and down, the 200L standard steel barrel will have the risk of shaking or tipping over. On the one hand, the shaking or tipping 200L standard steel barrel will affect the efficiency of nuclear power plant contaminated waste sorting and barreling. On the other hand, if the steel barrel containing nuclear power plant contaminated waste is tipped over, it will cause pollution to the surrounding environment. Therefore, a 200L standard steel barrel lifting mechanism for nuclear power plants is needed to solve the above problems. Utility Model Content

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, a 200L standard steel barrel lifting mechanism for nuclear power plants includes a main body bracket 1. A lifting platform 2 is movably installed on the main body bracket 1. One end of the lifting platform 2 is fixedly installed with an installation bracket 3. A driving assembly 4 is fixedly installed on the installation bracket 3. The driving assembly 4 is composed of a cylinder 12, a double-output shaft motor 13, a threaded rod 14, and a baffle 15. The double-output shaft motor 13 is fixedly installed at the upper end of the telescopic rod of the cylinder 12. There are two threaded rods 14 which are respectively fixedly connected to the two output shafts of the double-output shaft motor 13. There are two baffles 15 which are respectively fixedly installed at one end of the two threaded rods 14. Two clamping structures 5 are installed on the two threaded rods 14. The clamping structure 5 is composed of an arc-shaped clamping plate 16, a first connecting plate 17, a threaded sleeve 18, a second connecting plate 20, a guide rod 21, and a rubber pad 22. The first connecting plate 17 is fixedly installed on the arc-shaped clamping plate 16. The threaded sleeve 18 is fixedly installed at one end of the first connecting plate 17. The second connecting plate 20 is fixedly installed on the threaded sleeve 18. The guide rod 21 is fixedly installed at one end of the double-output shaft motor 13. The second connecting plate 20 is simultaneously movably sleeved on the guide rod 21. The rubber pad 22 is fixedly installed on the inner wall of the arc-shaped clamping plate 16. During use, the steel barrel for containing nuclear power plant contaminated waste can be placed on the upper end of the lifting platform 2. Then, the driving assembly 4 can be used to drive the two clamping structures 5 to move upward. Finally, the driving assembly 4 can be used to drive the two clamping structures 5 to approach each other until the two clamping structures 5 clamp and fix the steel barrel. Then, the lifting platform 2 can drive the steel barrel to move upward, so that the steel barrel is docked with the sorting hole in the sorting area, and the steel barrel is kept at a certain height and in a sealed state. When the steel barrel is filled with nuclear power plant contaminated waste, the lifting platform 2 will drive the steel barrel to move downward. By setting the driving assembly 4 and the clamping structure 5, the steel barrel placed on the lifting platform 2 can be limited and fixed, so as to prevent the steel barrel from shaking or tipping during the rising or falling process of the lifting platform 2. Furthermore, the efficiency of sorting and filling the steel barrel with nuclear power plant contaminated waste can be guaranteed, and at the same time, the pollution of the surrounding environment caused by the tipping of the steel barrel can be avoided.

[0022] Furthermore, a driving motor 6 is fixedly installed on the main body bracket 1. A driving sprocket 7 is fixedly installed on the output shaft of the driving motor 6. An eccentric wheel lifting mechanism 8 is installed on the main body bracket 1. A tensioning device 10 is also installed on the main body bracket 1. The driving sprocket 7 and the eccentric wheel lifting mechanism 8 are connected by a transmission chain 9. One end of the lifting platform 2 is fixedly installed with a position detection unit 11. The lifting platform 2 can move up and down on the main body bracket 1. During use, this lifting mechanism can be arranged directly below the sorting hole and at the middle position of the conveying roller path. When lifting the steel drum, the driving motor 6 drives the driving sprocket 7 to rotate. The driving sprocket 7 drives the upper eccentric wheel lifting mechanism 8 to rotate through the transmission chain 9. The contact point between the flat bar at the lower part of the lifting platform 2 and the cam rises or falls as the cam rotates, causing the lifting platform 2 to rise or fall. The position detection unit 11 is designed with two groups of sensors, one for low-position detection and one for high-position detection. During use, it can be adjusted according to the actual required lifting range. When lifting, the steel drum is docked with the sorting hole. When descending, the steel drum descends to the lateral conveying mechanism.

[0023] Furthermore, the cylinder 12 on the driving assembly 4 is fixedly installed on the mounting bracket 3. Two clamping structures 5 are arranged around the outside of the lifting platform 2. The threaded sleeve 18 on the clamping structure 5 is installed on the threaded rod 14. A limiting hole 19 is opened on the second connecting plate 20. The second connecting plate 20 is movably sleeved on the guide rod 21 through the limiting hole 19 opened thereon. When fixing the steel drum, first, the cylinder 12 on the driving assembly 4 is used to push the double-output shaft motor 13, the threaded rod 14, the baffle 15, and the clamping structure 5 upward. After the two clamping structures 5 are arranged around the outside of the steel drum, the double-output shaft motor 13 drives the threaded rod 14 to rotate, so that the two clamping structures 5 approach each other. Eventually, until the two clamping structures 5 clamp on the steel drum, at this time, the steel drum is clamped and fixed. When it is necessary to release the fixation of the steel drum, only need to use the double-output shaft motor 13 to drive the threaded rod 14 to reverse, so that the two clamping structures 5 move away from each other, and then use the cylinder 12 to reset the clamping structure 5 below the steel drum; when the clamping structure 5 clamps the steel drum, the rubber pad 22 will contact the steel drum. When the threaded rod 14 rotates, restricted by the guide rod 21, the arc-shaped clamping plate 16, the first connecting plate 17, the threaded sleeve 18, the second connecting plate 20, and the rubber pad 22 will not rotate with the threaded rod 14.
