[0024] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0025] like Figures 1-6 As shown, this embodiment provides a multi-station rotary lid-lifting device, including a rotating disk 1, multiple receiving cylinders 2, an ejection assembly 3, and a lid-lifting assembly 4.

[0026] A drive assembly is provided below the rotating disk 1. The drive assembly includes a drive motor and a gearbox. The middle part of the rotating disk 1 is fixedly connected to the gearbox. The output end of the drive motor meshes with the gear set inside the gearbox. The drive motor and gearbox are existing structures and will not be described in detail here.

[0027] The rotating disk 1 has multiple placement stations arranged in a ring at intervals along the axis of the rotating disk 1. The number of placement stations is most suitable to be 6-8. In this embodiment, there are 6 placement stations. Each placement station has a through hole 11. A limiting step 111 is provided at the lower end of the inner circle of the through hole 11. The inner diameter of the through hole 11 is adapted to the bottom of the receiving cylinder 2, and the inner diameter of the limiting step 111 is smaller than the bottom diameter of the receiving cylinder 2.

[0028] Six container cylinders 2 are placed in six placement stations. Each container cylinder 2 includes a cylinder body and a cover 21. The cover 21 is used to close the opening on the cylinder body. A protrusion 211 is formed on the upper surface of the cover 21. The protrusion 211 is made of ferromagnetic material.

[0029] The ejector assembly 3 is located below the placement station facing the output end of the cover assembly 4. The ejector assembly 3 is used to lift the receiving cylinder 2. The ejector assembly 3 can be a telescopic electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. A tray is set at the output end of the cylinder body to support the bottom of the receiving cylinder 2. The diameter of the tray is less than or equal to the inner diameter of the limit step 111.

[0030] The lifting assembly 4 is located on the upper surface of the center of the rotating disk 1. The lifting assembly 4 faces any placement station and is used to lift the cover 21 of the container cylinder 2 at that placement station. Specifically, the lifting assembly 4 includes an extension column 41, a follow-up detection rod 42, a first detector 43, a second detector 44, a mounting base 45, a rotating motor 46, a first connecting rod 47, a second connecting rod 48, a third connecting rod 49, and a suction head 491. The extension column 41 is located in the center of the rotating disk 1, and the mounting base 45 is located on the upper surface of the extension column 41. Specifically, a mounting plate is formed on the upper surface of the column, and the mounting base 45 is detachably connected to the mounting plate. Mounting base 45 has a side plate 451. Rotary motor 46 is mounted on side plate 451 and its output end passes through side plate 451. The output end of rotary motor 46 has a rotating platform 461. A protruding plate 462 is formed on one side of rotating platform 461. One end of first connecting rod 47 is hinged to the surface of protruding plate 462. The other end of first connecting rod 47 is connected to the surface of second connecting rod 48 through rotating column. Rotating column is hinged to first connecting rod 47 and fixedly connected to second connecting rod 48. One end of second connecting rod 48 is hinged to side plate 451. The other end of second connecting rod 48 is hinged to one end of third connecting rod 49. A suction head 491 is mounted on the other end of third connecting rod 49. Specifically, suction head 491 is an electromagnetic suction head 491. The vertical cross-section of the follow-up detection rod 42 is Z-shaped. One end of the follow-up detection rod 42 is connected to the side plate 451 through a fixed shaft. The connection between the fixed shaft and the follow-up detection rod 42 is hinged. The other end of the follow-up detection rod 42 is hinged to the side wall of the other end of the third connecting rod 49. The first detector 43 determines that the cover lifting assembly 4 is in the unopened state by detecting its proximity to the follow-up detection rod 42. The second detector 44 determines that the cover lifting assembly 4 is in the open state by detecting its proximity to the follow-up detection rod 42.

[0031] Among them, the first detector 43 and the second detector 44 are infrared detectors. The infrared detectors are self-emitting and self-receiving infrared sensors, such as single-sided diffuse reflection gratings. The position of the follow-up detection rod 42 is determined by the time difference between infrared emission and reception.

[0032] Preferably, the first detector 43 and the second detector 44 may also be selected from other sensors such as proximity switches that can sense the approach of the follow-up detection rod 42.

[0033] Preferably, the mounting base 45 is provided with a first extension plate 431 and a second extension plate 441. The first extension plate 431 and the second extension plate 441 are arranged vertically. The first detector 43 and the second detector 44 are respectively mounted on the first extension plate 431 and the second extension plate 441. The height of the first detector 43 and the second detector 44 is increased by the first extension plate 431 and the second extension plate 441, making it easier to adjust.

[0034] Working principle: When the rotating disk 1 drives one of its receiving cylinders 2 to rotate to below the cover lifting assembly 4, the ejector assembly 3 ejects and lifts the receiving cylinder 2, so that the protrusion 211 on the cover 21 of the receiving cylinder 2 comes into contact with the suction head 491. The suction head 491 is energized and attracts the protrusion 211. When the rotating motor 46 rotates 90 degrees clockwise, the protrusion 462 of the rotating table 461 moves downward, so that the first connecting rod 47 pulls the second connecting rod 48 to swing upward, thereby driving the third connecting rod 49 to lift up and realize the cover lifting. Then the rotating motor 46 continues to rotate clockwise. Under the action of the first connecting rod 47 and the second connecting rod 48, the end face of the third connecting rod 49 will be perpendicular to the horizontal plane, thereby realizing the vertical lifting of the cover 21, which is convenient for testing the concrete inside the cylinder. After the test is completed, the rotating motor 46 resets and the cover 21 is closed, and the ejector assembly 3 retracts.

[0035] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope.
