[0002] As one of the core equipment of stereoscopic warehouse, the laned stacking crane undertakes the task of storing and transporting goods. The current laned stacking crane usually adopts a relatively complex structure design. The mechanical transmission part often contains multiple independent structures, such as a stand, a walking system, a hydraulic lifting system and a fork telescopic mechanism, etc. These components work cooperatively through multiple connection methods, which greatly increases the complexity of the structure of the whole equipment. The complex structure not only increases the manufacturing difficulty and cost of the equipment, but also the mutual cooperation between the components is prone to failure during the operation of the equipment, and the difficulty of maintenance and repair is also correspondingly increased.

[0003] From the perspective of space occupation, the traditional laned stacking crane occupies a large area. On the one hand, its walking track needs to occupy a certain ground space, and the laying of the track needs to ensure a high flatness and accuracy, which further limits the effective use of the ground space of the warehouse. On the other hand, the structural size of the stacking crane itself is large, and when it runs in the laneway, enough safety space needs to be reserved to prevent the equipment from colliding with the shelves or other objects, which leads to the fact that the width of the laneway cannot be too narrow, thus occupying a lot of transverse space of the warehouse. In view of the above problems, the utility model provides a stereoscopic warehouse laned stacking crane with simple structure and small area. SUMMARY

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a stereoscopic warehouse laned stacking crane, comprising a cross beam, the bottom of the cross beam is provided with shelves at both ends, connecting rods are evenly welded between the shelves, the top of the shelf and the end of the cross beam are provided with sliding connections, a moving mechanism is arranged between the shelf and the cross beam, a base is slidingly connected to the top of the cross beam, a lifting frame is arranged at the bottom of the base, the base and the lifting frame are fixed by an electromagnet, a winch is fixed to the top of the base, the tail end of the wire rope of the winch is fixedly connected to the top of the lifting frame, sliding structures are arranged between the two sides of the lifting frame and the two shelves respectively, the sliding structure comprises a track groove and a multi-dimensional sliding shaft, the track groove is provided with a shelf side wall, the multi-dimensional sliding shaft is fixed to the four corners of the two sides of the lifting frame, and the two sides of the lifting frame and the two shelves are slidingly connected through the multi-dimensional sliding shaft and the track groove.

[0005] As a preferred technical scheme of the utility model, the track groove comprises a longitudinal groove and a transverse groove, the longitudinal groove and the transverse groove are arranged in a cross structure on the side of the shelf, and the longitudinal groove and the transverse groove are in communication with each other.

[0006] As a preferred technical scheme of the utility model, the multi-dimensional sliding shaft comprises a base, the base is fixed on the lifting frame, a sliding block is welded at the center of the base, an installation cavity is formed at one end of the sliding block, and a ball is installed in the installation cavity.

[0007] As a preferred technical scheme of the utility model, a rotating base is fixed at the center of the lifting frame, and an automatic fork is installed on the surface of the rotating base.

[0008] As a preferred technical scheme of the utility model, a guide rail is fixed at the top end of the goods shelf, a pulley is fixed at the end of the cross beam, and the pulley is fixed in the guide rail.

[0009] As a preferred technical scheme of the utility model, the moving mechanism comprises a driving motor and a rack, the rack is fixed at the top end of the goods shelf, the body of the driving motor is fixed on the cross beam, a gear is fixed at the output end of the driving motor, and the gear is connected with the rack in meshing mode.

[0010] Compared with the prior art, the utility model has the advantages of:

[0027] The automatic forks 15 and the rotating base 14 in this embodiment are known technologies widely used in daily life, and their structural design and working principle are known to those skilled in the art. The automatic forks 15 are usually made of high-strength steel, which has good rigidity and toughness and can withstand the task of picking up and carrying certain weight of goods. In actual operation, the extension and retraction of the forks are precisely controlled through a gear and rack transmission system (or a hydraulic cylinder transmission) driven by a motor, so that the goods can be quickly and smoothly picked up. The extension stroke can be customized according to actual storage needs to meet the storage and retrieval operations of different depth storage locations. The rotating base 14 can adjust the angle of the goods in the horizontal direction. It generally has a built-in precision bearing and driving device, which is powered by a motor and driven by a belt or gear transmission to rotate the rotating base 14 within a range of 360 degrees. This function is very useful in the process of goods handling, which can flexibly adjust the goods to the appropriate direction, facilitate accurate storage or retrieval of the goods, and greatly improve the efficiency and accuracy of goods storage and retrieval. In this three-dimensional warehouse roadway type stacking crane, these mature technologies are reasonably integrated and work with other innovative structures of the stacking crane.

[0028] In summary, by means of the above technical scheme of the utility model,

[0029] Horizontal movement principle: The horizontal movement of the stacking crane is realized through the movement mechanism between the rack 2 and the cross beam 1. The driving motor 18 in the movement mechanism is fixed on the cross beam 1, and the gear 20 at the output end of the driving motor 18 is engaged with the rack 19 fixed on the top end of the rack 2. When the driving motor 18 is powered on and operates, the torque generated by the motor is transmitted to the gear 20 through the output shaft. Due to the engagement relationship between the gear 20 and the rack 19, the rotary motion of the gear 20 is converted into the linear motion of the cross beam 1 relative to the rack 2. At the same time, the pulley 17 at the end of the cross beam 1 rolls in the guide rail 16 at the top end of the rack 2, which serves as auxiliary support and guide to ensure that the cross beam 1 moves stably along the length direction of the rack 2, thereby driving the entire stacking crane to be positioned in the horizontal direction in the roadway and reach the designated goods storage column position.

[0030] The vertical lifting and horizontal moving principle: the vertical lifting of the lifting frame 4 relies on the cooperation of the winch 5 on the top of the base 3 and the sliding structure between the lifting frame 4 and the shelf 2. When the winch 5 is powered on, the motor inside the winch 5 drives the winding drum to rotate and wind or unwind the steel wire rope. The tail end of the steel wire rope is fixedly connected to the top of the lifting frame 4. When the winch 5 winds the steel wire rope, the lifting frame 4 is pulled upward; when the winch 5 unwinds the steel wire rope, the lifting frame 4 moves downward under the action of its own gravity. The multi-dimensional sliding shaft 7 at the four corners of the two sides of the lifting frame 4 is slidably connected with the track groove 6 of the side wall of the shelf 2, which stabilizes and guides the lifting process of the lifting frame 4. The track groove 6 is composed of a longitudinal groove 8 and a transverse groove 9 in a cross structure and is in communication with each other. The base 10 of the multi-dimensional sliding shaft 7 is fixed on the lifting frame 4, the sliding block 11 welded at the center of the base 10 is embedded in the track groove 6, and the end of the sliding block 11 is installed in the cavity 12 with the ball 13 in contact with the inner wall of the track groove. During the lifting process of the lifting frame 4, the ball 13 rolls in the longitudinal groove 8, which not only reduces the frictional resistance but also adapts to the slight deviation of the lifting frame 4 in the vertical direction, thereby ensuring the stability and accuracy of the lifting movement. When horizontal translation is needed, the lifting frame 4 is lifted to the top end by winding the steel wire rope with the winch 5, the electromagnet installed at the bottom of the base 3 is powered on to attract the magnetic metal at the top end of the lifting frame 4, thereby fixing the lifting frame 4 at the bottom of the base 3. The distance between the two multi-dimensional sliding shafts 7 on the side surface of the lifting frame 4 and the distance between the two transverse grooves 9 at the top are equal, the moving mechanism drives the entire cross beam 1 to move horizontally, and at the same time, the sliding blocks 11 of the multi-dimensional sliding shafts 7 on the two sides of the lifting frame 4 move horizontally in the transverse grooves 9 of the track grooves 6 at the top end, until they are moved to the target position, the electromagnet at the bottom of the base 3 is de-energized, the lifting frame 4 is released, and the goods are lowered to the target height by winding the steel wire rope with the winch 5.

[0031] The goods storage and retrieval principle: when the stacking crane reaches the target goods position through horizontal movement and vertical lifting, the goods storage and retrieval operation begins. First, the automatic fork 15 is rotated by rotating the rotating base 14 in the center of the lifting frame 4, and then the automatic fork 15 is installed on the surface of the rotating base 14. The automatic fork 15 is used for picking up goods in the horizontal direction, and the goods are picked up by the automatic fork 15. After the goods are picked up, the automatic fork 15 is retracted to the initial position, and the goods are brought back to the rotating base 14 of the lifting frame 4. When storing goods, the process is reversed, the automatic fork 15 is first extended to place the goods at the designated location of the shelf 2, and then retracted, completing the entire goods storage and retrieval process.
