[0027] Example:

[0028] A lifting and translation mechanism, Figure 1 As shown, it includes a first frame, a second frame and a lifting platform arranged between the first frame and the second frame. The first frame and the second frame are both in the shape of two rectangular flat plates with their corner points aligned and connected by columns. The two rectangular flat plates are formed with an upper platform and a lower platform. The upper platform and the lower platform of the first frame and the second frame are aligned and have the same height.

[0029] The lifting method of the lifting platform is as follows:

[0030] The lifting platform comprises a rectangular lifting plate, a first frame body, a guide column fixed on a column of a second frame body close to the lifting plate, and a climbing member that realizes climbing through the guide column, and the climbing member is driven by a motor.

[0031] Among them, the implementation in this embodiment is as follows:

[0032] Ginseng Figure 2 As shown, the lifting platform includes a lifting plate, a cylindrical rack fixedly connected to the first frame and the second frame, a lifting motor, and a climbing gear installed on the lifting plate and driven by the lifting motor. The cylindrical rack is arranged near the corner point of the lifting plate, and the lifting plate is driven to lift by the climbing gear and the cylindrical rack meshing. The lifting plate can be lifted and lowered horizontally by the cooperation of the climbing gear and the cylindrical rack. The cylindrical rack of the rod body arranged on the first frame and the second frame is used as a guide, and the climbing gear and the cylindrical rack meshing are meshed to achieve the driving effect. The meshing includes meshing forms such as synchronous belt and synchronous wheel, gear and rack.

[0033] In other embodiments, the climbing member is a slider threadedly connected to the guide column, and the lifting plate can be driven to rise and fall by driving the slider to rotate.

[0034] In this embodiment, the transmission between the climbing gear and the driving motor is specifically implemented as follows:

[0035] The lifting motor is fixedly connected to the back of the lifting plate, and the output shaft of the lifting motor drives the first transmission shaft arranged along the first direction through the first reducer. The two ends of the first transmission shaft are respectively connected to the second reducer, and the output end of the second reducer drives the second transmission shaft arranged along the second direction to rotate. The climbing gear is set at both ends of the second transmission shaft. The first transmission shaft transmits power to the second transmission shaft, and the second transmission shaft transmits power to the climbing gear, thereby realizing the synchronous operation of each climbing gear.

[0036] The lifting platform is also connected to a counterweight system, which includes a belt, a support wheel system and a counterweight block. The support wheel system is arranged on the first frame or the second frame. The two ends of the belt are respectively connected to the lifting platform and the counterweight. The positions of the blue screens of each belt on the lifting platform are symmetrical relative to the central axis in the width or length direction of the lifting platform. Through the counterweight system, the weight of the lifting platform and the load thereon is reduced through the cylindrical rack and the climbing gear, thereby increasing the life of the entire mechanism.

[0037] Of course, providing a self-locking member similar to a worm gear in the first reducer and the second reducer can also achieve the purpose of self-locking without a counterweight system, thereby reducing the burden on the motor.

[0038] Ginseng Figure 1 As shown, the upper platform, the lower platform and the lifting platform are all provided with a translation conveying structure, which provides lengthwise movement for the object. When the lifting platform moves to a position aligned with the upper platform or the lower platform, the object can be transferred between the first frame, the second frame and the lifting platform by the translation conveying structure.

[0039] The translation conveying structure includes a translation transmission rod, a driving motor and a belt. Adjacent translation transmission rods are connected by belts, and the driving motor drives a translation transmission rod. The object to be moved is placed on the translation transmission rod, and the translation transmission rod rotates synchronously, and performs rolling friction with the object to realize the transportation of the object. The translation transmission rod rotates synchronously through the driving motor, and the driving motor drives a translation transmission rod, and adjacent translation transmission rods are driven by belts.

[0040] There are three translational transmission rods, and the output shaft of the driving motor is fixedly connected to the middle translational transmission rod. Both ends of the translational transmission rod are installed on the tensioning adjustment frame, and the tensioning adjustment frame can adjust the distance between adjacent translational transmission rods. The structure is used to achieve the tensioning of the belts between the translational transmission rods, thereby achieving the transmission purpose. The mobile transmission rod is rotatably connected to the bearing seat through a bearing, and the tensioning adjustment frame is threadedly connected with positioning screws at both ends in the length direction. The bearing seat is slidably connected to the tensioning adjustment frame along the length direction, and the positioning screw abuts the bearing seat. The specific tensioning method is to adjust the extension amount by connecting the positioning screw to the tensioning adjustment frame through a thread, and abut the bearing seat, thereby driving the bearing seat to move on the tensioning adjustment frame to achieve the tensioning purpose.

[0041] The first frame and the second frame are frames with two upper and lower planes of equal height, and the lifting platform between the two can reach a height level with the two planes. The planes constitute a platform. Through the translation conveying structure, the objects on the platform can be transported horizontally, so as to move between different platforms. With the lifting function of the lifting platform, the objects can move between different heights, so that the objects on the first frame or the second frame can reach any platform.

[0042] The structure occupies less area, is adaptable to narrow sites, and does not require the intervention of a forklift.
