Description

A bottom-modular stacker crane and its assembly method Technical Field

[0001] This invention relates to the field of stacker crane technology, specifically to a bottom-modular stacker crane and its assembly method. Background Technology

[0002] Stacker cranes, as large lifting and transportation equipment, have traditionally been shipped as components such as the base frame, columns, lifting platform, and top beam. On-site assembly of these components involves multiple hoisting operations, followed by wiring and electrical component installation, and finally, on-site electrical commissioning. This process is slow and inefficient. Furthermore, issues such as missing parts, component quality problems, or wiring issues can occur, ultimately affecting product delivery. Therefore, effectively controlling the quality of stacker crane electrical components and assembly within the factory to improve the reliability, reliability, convenience, and efficiency of on-site installation, commissioning, and delivery has become a pressing technical challenge. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems by providing a bottom-modular stacker crane and its assembly method. This method integrates the main components of the stacker crane into a bottom module, enabling in-plant assembly and adjustment, on-site hoisting, and quality control, thereby improving on-site implementation quality and efficiency.

[0004] The technical solution of the present invention is as follows:

[0005] A bottom-module stacker crane includes a bottom module, which includes a fixed-height column and a variable-height column. The fixed-height column is vertically connected to the base frame. A lifting platform is provided on the fixed-height column for lifting and lowering along the column. Forks for storing and retrieving materials are provided on the lifting platform, which is driven by a lifting drive device. A top beam is provided on the top of the bottom module. An electrical control system is also provided on the base frame.

[0006] Furthermore, the fixed-height column can be a single column or a double column. A single column forms a structure with the base frame, and a double column forms a structure with the base frame.

[0007] Furthermore, the base frame is supported by a support assembly.

[0008] Furthermore, the variable-height column is mounted on the base frame.

[0009] Furthermore, steel wire ropes are installed on the variable-height column.

[0010] Furthermore, the bottom module can be tested on an in-plant testing platform. After passing the test, the bottom module is packaged and shipped.

[0011] This application also includes a bottom-modular stacker crane assembly method, comprising the following steps:

[0012] After the ground rail is installed, the bottom module can be hoisted into place on the ground rail, or the bottom module can be directly pushed into the ground rail using four support components;

[0013] Adjust the bottom module to the correct position based on the ground rail and fix it. For the double column structure, move the top beam to the variable height column.

[0014] The variable-height column is connected to the fixed-height column of the bottom module, and the entire column is adjusted to ensure the form and position tolerance requirements. After adjusting the guide and corresponding spacing of the top beam and the overhead rail, the steel wire rope is arranged.

[0015] Install the remaining functional modules and components, such as power supply devices and safety ladders, to complete the equipment operation of the stacker crane;

[0016] After local inspection and adjustment, the stacker crane can be powered on and operated manually. After further debugging, the stacker crane can run automatically.

[0017] Compared with existing technologies, the advantages of this invention are:

[0018] 1. A bottom-modular stacker crane and its assembly method. The bottom module standardizes and modularizes the main components of the stacker crane, transforming it from customized production to small-batch production, thus improving product quality and manufacturing efficiency. The main components are assembled in the factory to ensure higher installation precision. Electrical components are installed and wired in the factory, and the entire machine is tested and debugged in-factory using a testing platform. After passing the tests, the machine is shipped. On-site installation of components such as the height-adjustable columns and top beams allows for manual operation upon power connection. This improves the reliability, reliability, convenience, and efficiency of on-site installation, commissioning, and delivery of the stacker crane.

[0019] 2. A bottom-module stacker crane and its assembly method, wherein a support component is provided on the bottom module to facilitate the positioning of the bottom module. The support component can directly position the bottom module on the ground rail during installation and also plays a role in stabilizing the bottom module. Attached Figure Description

[0027] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0028] Please refer to Figures 1-5. A bottom-modular stacker crane, as shown in Figures 1, 2, and 3, includes a bottom module. The bottom module includes a fixed-height column 2 and a variable-height column 10. The fixed-height column 2 is vertically connected to the base frame 1. A lifting platform 3 is provided on the fixed-height column 2 for lifting and lowering along the column 2. The lifting platform 3 is equipped with forks 4 for storing and retrieving materials and is driven by a lifting drive device 5. A top beam 6 is provided on the top of the bottom module. An electrical control system device 7 is also provided on the base frame 1. A section of the fixed-height column 2, the base frame 1, the lifting platform 3, the lifting drive, and the electrical control system device 7 are used to form the bottom assembly. The bottom module is ultimately formed by modular design of the components through analysis and statistics of the weight and dimensions of the stored and retrieved materials.

[0029] The bottom module standardizes and modularizes the main components of the stacker crane, transforming it from customized production to small-batch production, thus improving product quality and manufacturing efficiency. This allows for the assembly of major components in the factory, ensuring higher installation precision. Electrical components are installed and wired in the factory, achieving in-factory debugging and testing of the entire machine via a testing platform. After passing the tests, the machine is shipped. On-site installation of components such as the height-adjustable columns and top beams is then completed, and manual operation is possible upon power connection. This improves the reliability, reliability, convenience, and efficiency of on-site installation, commissioning, and delivery of the stacker crane.

[0030] The fixed-height column 2 can be a single column or a double column. A single column forms a structure with the base frame 1, and a double column forms a structure with the base frame 1.

[0031] The base frame 1 is supported by the support assembly 8. To facilitate the placement of the bottom module, the support assembly is set on the base of the bottom module. The support assembly allows the bottom module to be directly placed on the ground rail during installation and also serves to stabilize the bottom module.

[0032] The height-adjustable column 10 is installed on the base frame 1.

[0033] A steel wire rope 11 is installed on the height-adjustable column 10.

[0034] The bottom module can be powered on and tested on the factory test platform 9. After passing the test, the bottom module is packaged and shipped.

[0035] This application also includes a bottom-modular stacker crane assembly method, comprising the following steps:

[0036] After the ground rail is installed, the bottom module can be hoisted into place on the ground rail, or the bottom module can be directly pushed into the ground rail using four support components;

[0037] Adjust the bottom module to the correct position based on the ground rail and fix it. For the double column structure, move the top beam to the variable height column.

[0038] The variable-height column is connected to the fixed-height column of the bottom module, and the entire column is adjusted to ensure the form and position tolerance requirements. After adjusting the guide and corresponding spacing of the top beam and the overhead rail, the steel wire rope is arranged.

[0039] Install the remaining functional modules and components, such as power supply devices and safety ladders, to complete the equipment operation of the stacker crane;

[0040] After local inspection and adjustment, the stacker crane can be powered on and operated manually. After further debugging, the stacker crane can run automatically.

[0041] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
