Description

Technical Field

[0001] This utility model relates to the field of stacker cranes, and in particular to a stacker crane with precise cargo positioning function. Background Technology

[0002] As the core handling equipment in modern automated warehouses, stacker cranes' core function is to enable rapid and accurate storage and retrieval of goods between racks and entry / exit points. Existing stacker crane platforms primarily employ rigid grippers or fixed baffle structures, which suffer from the following problems: poor adaptability: the fixed gripper size cannot accommodate goods of different dimensions; gripping irregularly shaped goods is inconvenient; and the gripping force is unevenly distributed. Therefore, we propose a stacker crane with precise goods positioning capabilities. Utility Model Content

[0003] To address the technical problem of inconvenient clamping in existing stacker cranes, this utility model provides a stacker crane with precise cargo positioning function.

[0004] This utility model is achieved by the following technical solution: a stacker crane with precise cargo positioning function, including a machine frame, a support plate fixedly connected to the top of the machine frame, a lifting mechanism for lifting the loading platform installed above the support plate, a cargo self-positioning mechanism installed inside the loading platform; and an electrical cabinet platform installed on the outside of the machine frame.

[0005] The lifting mechanism includes a mounting bracket, which is fixedly mounted on the surface of a support plate. A working motor is mounted on the surface of the mounting bracket, and a take-up roller is connected to the output end of the working motor. A lifting steel cable is wound around the surface of the take-up roller, and the lifting steel cable overlaps the surface of a limit wheel. The limit wheel is mounted on the inner side of the mounting bracket, and a locking block is connected to the bottom end of the lifting steel cable. The locking block is fixedly connected to the top of the platform. A pulley block is mounted on the side wall of the platform, and the pulley block is engaged with a lifting column. The lifting column is mounted on the inner wall of the machine support.

[0006] The cargo autonomous positioning mechanism includes a carrying plate, a connecting frame fixedly connected to the bottom of the carrying plate, a receiving platform connected to the bottom of the connecting frame, an electric push rod connected to the bottom of the receiving platform, a connecting shaft block fixedly installed on the outer edge of the surface of the receiving platform, one end of a motion shaft clamped on the inner side of the connecting shaft block, and a through shaft passing through the connection between the connecting shaft block and the motion shaft.

[0007] The other end of the motion shaft is connected to a mounting bracket, the bottom of which is connected to a sliding block. The bottom of the sliding block is slidably engaged with a sliding frame, which is in a cross shape. The bottom end of the electric push rod is mounted on the surface at the intersection of the sliding frames. A positioning bracket is connected above the mounting bracket, and a limit bolt is fixedly installed on the surface of the positioning bracket. A pressure sensor is installed on the inner side of the limit bolt.

[0008] When the goods are placed on the platform, the electric push rod retracts, causing the receiving platform connected above it to move downwards simultaneously. The connecting shaft block and the moving shaft connected to the outside of the receiving platform move synchronously, and the moving shaft then drives the mounting frame to move. The mounting frame drives the sliding block to slide, and the sliding block then slides along the track on the sliding frame. The sliding block then drives the positioning frame connected above it to move inwards synchronously, and the four sets of opposing positioning frames position the goods. The limit bolts on the positioning frames then position the goods. A pressure sensor is installed between the limit bolts and the positioning frames to detect the pressure. After the goods are clamped, the electric push rod stops clamping.

[0009] As a further improvement to the above solution, the limiting bolt has a conical protrusion. The conical limiting bolt on the positioning frame is embedded in the groove or gap at the bottom of the cargo, forming multi-point restraint and further suppressing cargo displacement.

[0010] As a further improvement to the above scheme, the lifting mechanism is further provided in two sets, and the lifting cables on the two sets of lifting mechanisms are connected to both sides of the platform.

[0011] As a further improvement to the above scheme, the lifting mechanism adopts two sets of symmetrically arranged lifting steel cables, and ensures that the force on both sides of the platform is uniform through the guidance of limit wheels and the cooperation of pulley blocks and lifting columns.

[0012] As a further improvement to the above solution, a working motor drives the take-up roller to rotate, synchronously lifting the platform via two sets of lifting steel cables. The cables are guided by limit wheels to ensure balanced force on both sides of the platform. The cooperation between the pulley system and the lifting column enhances lifting stability and reduces swaying.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The cargo self-positioning mechanism of this utility model uses four sets of opposing positioning frames for positioning. The limiting bolts on the positioning frames then position the cargo. The conical limiting bolts on the positioning frames are embedded in the grooves or gaps at the bottom of the cargo to form multi-point constraints, further suppressing cargo displacement. It can clamp various irregularly shaped cargoes and ensure the stability of clamping.

[0015] 2. The lifting mechanism of this utility model adopts two sets of symmetrically arranged lifting steel cables. Through the guidance of limit wheels and the cooperation of pulley blocks with the lifting column, it ensures that the force on both sides of the platform is uniform. The double steel cable design greatly reduces the swaying caused by uneven force on one side. Combined with the real-time correction function of the cargo autonomous positioning mechanism, it significantly improves the stability of the platform during the lifting process, and is especially suitable for high-precision warehousing scenarios.
