Description

Technical Field

[0001] This utility model belongs to the technical field of stacker crane equipment, specifically, it relates to a drive device for a stacker crane. Background Technology

[0002] With the continuous upgrading and improvement of modern logistics systems, automated intelligent warehouses have become key facilities for improving warehousing efficiency, optimizing space utilization, and achieving refined supply chain management. Their application scope is rapidly expanding, widely covering many important industries such as automobile manufacturing, electronics and communications, pharmaceutical production, tobacco logistics, and building materials warehousing. As the core handling equipment in automated warehouses, stacker cranes are responsible for the storage, retrieval, handling, and precise positioning of goods between the racks. Their performance directly affects the inbound and outbound efficiency, operational stability, and long-term operating costs of the entire warehouse unit.

[0003] Among the various components of a stacker crane, the drive unit is particularly crucial. Like the "heart" of the equipment, it provides power for horizontal movement and vertical lifting, directly affecting the stacker crane's acceleration, deceleration, positioning accuracy, and continuous operating capability. For example... Figure 1 As shown, currently, many existing stacker crane equipment use a structural design where the drive unit is directly fixed to the lower crossbeam.

[0004] While this design is simple and rigid in the initial installation phase, its shortcomings become apparent in maintenance and repair after long-term operation. If the drive unit malfunctions or requires regular maintenance, maintenance personnel often have to disassemble the stacker crane extensively, sometimes even removing the entire drive mechanism along with related structural components. This maintenance method is not only complex and time-consuming, but also significantly increases equipment downtime, severely impacting the continuous operation rhythm of the warehouse, thereby reducing overall logistics efficiency and adversely affecting the company's production plans and order response speed. Utility Model Content

[0005] The purpose of this utility model is to provide a drive device for a stacker crane, which solves the technical problem in the prior art where the drive device of the stacker crane is directly fixed to the lower crossbeam, requiring the entire machine to be stopped and disassembled during maintenance, which is not only inconvenient for maintenance and repair but also reduces production efficiency.

[0006] The objective of this utility model can be achieved through the following technical solutions: A stacker crane drive device includes a lower crossbeam body, which is composed of two side plates and an I-beam connecting the two side plates. Both ends of the lower crossbeam body are respectively provided with an active travel wheel assembly and a driven travel wheel assembly, each including a travel wheel that abuts against a lower bottom track. Guide wheel assemblies are also provided at both ends of the lower crossbeam body. Both ends of the lower crossbeam body are respectively connected by screws to an active travel wheel fixing part and a driven travel wheel fixing part, which are used to install the active travel wheel assembly and the driven travel wheel assembly, forming a modular connection structure.

[0007] Furthermore, the guide wheel assembly includes an L-shaped mounting base that is bolted to the active travel wheel fixing part and the driven travel wheel fixing part respectively, forming a modular connection structure.

[0008] Furthermore, the bottom of the mounting base is bolted to two symmetrically arranged guide wheel bodies, which are located on both sides of the I-shaped track and abut against the side wall of the track.

[0009] Furthermore, the two mounting seats, located on opposite sides, are bolted together with symmetrically arranged anti-tilting safety hooks. These anti-tilting safety hooks are L-shaped and are positioned on both sides of the track, with a clearance fit to the track sidewall.

[0010] Furthermore, a communication ranging unit is connected to the upper part of the active walking wheel fixing part by screws, forming a modular connection structure.

[0011] Furthermore, the lower crossbeam body is fixedly connected to a speed limiter unit at one end near the active walking wheel fixing part by screws, forming a modular connection structure.

[0012] Furthermore, a deceleration limit switch unit is fixedly connected to one end of the lower crossbeam body near the driven wheel fixing part by screws, forming a modular connection structure.

[0013] Furthermore, the upper surface of the lower crossbeam body is bolted to both ends with column mounting plates, forming a modular connection structure.

[0014] Furthermore, buffer blocks are threadedly connected to the upper surface of the lower crossbeam body at positions located inside the column mounting plate, forming a modular connection structure.

[0015] The beneficial effects of this utility model are as follows: The stacker crane provided by this utility model adopts an open structure for its lower crossbeam body, which can be fixed with any speed limiter unit, deceleration limit switch unit, communication ranging unit, buffer block, and column mounting plate by means of screws, bolts, etc., providing flexible installation. Furthermore, the guide wheel assembly can be detachably connected to the active and driven wheel fixing parts via mounting bases, allowing for modular design between the components and each unit, especially core components such as the drive wheels and guide wheels. This not only significantly reduces installation difficulty but also saves considerable time for later maintenance and improves production efficiency. The modular design of this stacker crane drive device significantly improves equipment performance and maintenance efficiency, solving the problem of "replacing everything if one part is damaged" in traditional drive devices.
