DETAILED DESCRIPTION
[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] See also Figures 1 to 4 As shown, a container spreader rotary lock opening and closing detection device comprises: a plate body 1, four ear blocks 2 are symmetrically arranged on the left and right sides of the plate body 1, a lifting ring 12 is arranged in the middle of the top of the plate body 1, the ear block 2 vertically penetrates and is slidably connected with a sliding block 3, a mounting block 4 is fixedly connected to one side of the top of the sliding block 3, a pressure sensor 5 is arranged on the top of the ear block 2, the pressure sensor 5 cooperates with the mounting block 4, and the bottom end of the mounting block 4 contacts and cooperates with the top pressure input end of the pressure sensor 5; the lower part of the sliding block 3 is connected to the upper part of the rotary lock, and the lower part of the rotary lock is fixedly connected to the top of the container.
[0025] In this embodiment, a vertical sliding hole is opened in the middle of the top end of the ear block 2, and the sliding block 3 is vertically slidably connected in the vertical sliding hole.
[0026] In this embodiment, the rotary lock includes: a rotating block 6, a limit block 7, a positioning block 8 and a sliding groove 9. The rotating block 6 is connected to the bottom of the sliding block 3 along its circumferential rotation. The bottom end of the rotating block 6 is fixedly connected to the limit block 7. The bottom end of the positioning block 8 is fixedly connected to the top of the container. The interior of the positioning block 8 is hollow. A sliding groove 9 matching the limit block 7 is provided at the top of the positioning block 8. The sliding groove 9 is connected to the circular inner cavity of the positioning block 8. The limit block 7 is rectangular. The length and width of the sliding groove 9 are the same as the length and width of the limit block 7; the limit block 7 can rotate in the circular inner cavity and contact and cooperate with the top wall of the circular inner cavity of the positioning block 8. The positioning block 8 is provided with a driving component for driving the limit block 7 to rotate; the limit block 7 is slid into the positioning block 8 through the sliding groove 9. At this time, the pushing ball 11 does not contact the limit block 7. At this time, the threaded rod 10 is rotated, and the rotation of the threaded rod 10 drives the pushing ball 11 to move in the direction close to the limit block 7. During the displacement process, the pushing ball 11 contacts the limit block 7 , and push the limit block 7 to rotate. During the rotation of the limit block 7, the limit block 7 and the sliding groove 9 are misaligned, so that the limit block 7 cannot be taken out from the positioning block 8, and then the limit block 7 is fixed and connected with the positioning block 8. Then, when the plate body 1 and the container are lifted by the lifting ring 12 on the plate body 1, the weight of the container evenly applies a downward pulling force to the four sliding blocks 3, and then synchronously applies a downward pulling force to the mounting block 4, and then synchronously applies pressure to the four pressure sensors 5. After the positioning block 8 and the limit block 7 are fixed, during the lifting of the container, when the pressure on the pressure sensor 5 is less than a certain threshold, it can be judged that the positioning block 8 corresponding to the current pressure sensor 5 is not connected or the connection is not tight, so it has not been subjected to force or the force is too small, and there is no need for manual detection, and then the safety of the current container lifting is detected, thereby increasing the stability and safety of the device and avoiding dangerous accidents.
[0027] In this embodiment, a rotating groove 14 is provided at the bottom end of the sliding block 3, and a rotating ball 13 is fixedly connected to the top of the rotating block 6. The diameter of the rotating ball 13 is larger than the diameter of the rotating block 6, and the center of the rotating ball 13 is colinear with the axial direction of the rotating block 6. The rotating ball 13 is rotatably connected to the top of the rotating groove 14, and the rotating block 6 and the side wall clearance of the rotating groove 14 are matched; so that the rotating block 6 can only rotate and will not move up and down, so that the positioning block 8 is connected to the sliding block 3 and will not fall off, thereby increasing the stability of the device and preventing the limit block 7 from falling under force.
[0028] In this embodiment, the driving assembly includes: a threaded rod 10 and a pushing ball 11. The threaded rod 10 penetrates from the outside to the inside and is threadedly connected to the arcuate side wall of the positioning block 8. The pushing ball 11 is fixedly connected to the inner end of the threaded rod 10. The pushing ball 11 is arranged in the circular inner cavity of the positioning block 8, and the pushing ball 11 contacts and cooperates with one side of the side wall of the limit block 7. A rotating handle is arranged at the outer end of the threaded rod 10. The pushing ball 11 pushes the limit block 7 to rotate, so that the limit block 7 rotates and is misaligned with the sliding groove 9, thereby fixing the limit block 7 and the positioning block 8. The installation and disassembly are relatively convenient, and the threaded rod 10 itself has self-locking properties, so the limiting is reliable, which saves manpower and improves the safety of the device.
[0029] Working principle: when the device is used, a rotating pushing ball 11 is fixedly connected to one end of the threaded rod 10 extending into the positioning block 8; the limit block 7 is slid into the positioning block 8 through the sliding groove 9, at this time the pushing ball 11 is not in contact with the limit block 7, at this time the threaded rod 10 is rotated, the rotation of the threaded rod 10 drives the pushing ball 11 to move in the direction close to the limit block 7, during the displacement process the pushing ball 11 contacts the limit block 7 and pushes the limit block 7 to rotate, during the rotation of the limit block 7 the limit block 7 and the sliding groove 9 are misaligned, so that the limit block 7 cannot be removed from the positioning block 8, so that the limit block 7 and the positioning block 8 are fixed and connected, and then when When the plate body 1 and the container are lifted by the lifting ring 12 on the plate body 1, the weight of the container evenly applies a downward pulling force to the four sliding blocks 3, and then synchronously applies a downward pulling force to the mounting block 4, and then synchronously applies pressure to the four pressure sensors 5. After the positioning block 8 and the limit block 7 are fixed, during the lifting of the container, when the pressure applied to the pressure sensor 5 is less than a certain threshold, it can be determined that the positioning block 8 and the limit block 7 corresponding to the current pressure sensor 5 are not connected or the connection is not tight, so they have not been subjected to force or the force is too small, and then the safety of the current container lifting is detected, thereby increasing the stability and safety of the device and avoiding dangerous accidents.
