Description

Technical Field

[0001] The utility model specifically relates to the technical field of warehousing and transportation motors, in particular to a brushless DC motor used for driving intelligent warehousing and logistics. Background Art

[0002] Warehouse logistics generally utilizes transportation equipment to move objects. Flatbed transport vehicles are used to move objects to designated locations in the warehouse. The transport vehicle's floor is generally driven by a motor as a power source. Motors are often used to drive various equipment, such as automated transport vehicles, conveyor belts, and sorting systems.

[0003] However, in practice, people have noticed that warehouse transport vehicles require different loads when transporting objects of different weights. Motors with larger loads are prone to energy waste, while motors with smaller loads are prone to motor overload. Therefore, it is impossible to balance the load and energy consumption of the motor when transporting objects of different weights. In addition, most transport vehicles have complex structures and can only move in one direction. They cannot be flexibly moved according to the storage location of the objects, and their versatility is low. Utility Model Content

[0004] The purpose of this utility model is to provide a brushless DC motor for driving intelligent warehousing and logistics. The brushless DC motor is used as a driving source to reduce noise during driving. The two driving sources can be adjusted at any time according to demand, meeting requirements while reducing energy consumption. An internal track is also reserved for installing a moving mechanism, increasing the number of applications. This solves the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A brushless DC motor for driving intelligent warehousing and logistics, comprising a support beam frame, with end frames welded to both ends of the support beam frame, a reducer fixedly connected to each end frame, and a drive motor connected to the side of the reducer;

[0007] Both sides of the reducer are connected to the transmission shaft, and one end of each transmission shaft away from the reducer is fixedly connected to the guide wheel. Both sides of each guide wheel are movably connected to the end fixer, and the end fixer is fixedly connected to the end frame.

[0008] As a further technical solution of the present invention, the end frame includes a connecting plate, on which the end frame and the side frame are symmetrically welded, and the end portions of the end frame and the side frame are welded to form a rectangular frame, and reinforcing beams are symmetrically welded between the two side frames, and a fixing seat is welded between the two reinforcing beams.

[0009] As a further technical solution of the present invention, support frames are symmetrically welded to the sides of the connecting plates, and a cavity is provided on the inner side of the support frames. U-shaped grooves with upward openings are provided on both sides of each support frame.

[0010] As a further technical solution of the present invention, the guide wheel is located at the inner end of the support frame, and the end of the transmission shaft passes through the U-shaped groove and is movably connected to the end fixer.

[0011] As a further technical solution of the present invention, the end retainer includes a bearing sleeve, which is symmetrically fixedly connected to both sides of the support frame. The inner side of the bearing sleeve is interference fit with a fixed bearing, and the inner ring of the fixed bearing is interference fit with the transmission shaft.

[0012] As a further technical solution of the present invention, each end of the transmission shaft is fixed with a sleeve coupling by bolts, and the sleeve coupling is fixedly connected to both ends of the output shaft of the reducer by bolts.

[0013] As a further technical solution of the present invention, the drive motor is fixedly connected to the output end of the reducer by bolts, and the output shaft of the drive motor is connected to the input shaft of the reducer by a coupling.

[0014] As a further technical solution of the present invention, a flat plate is welded to the bottom of the support beam frame, and the flat plate is located between the two end frames.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In the utility model, the driving motor drives the input shaft of the reducer to rotate, and the output shaft of the reducer drives the transmission shaft to rotate. The power on the driving motor is divided into two by the reducer and supplied to the transmission shafts on both sides respectively, thereby driving multiple guide wheels to move simultaneously to move the object;

[0017] The utility model comprises a frame composed of a connecting plate, an end frame, a side frame and a reinforcement beam, which can support the supporting beam frame so that objects can be moved to a designated position along the track. The side frames symmetrically arranged on both sides of the flat plate can act as tracks. According to the use of the warehouse, a moving mechanism can be added to the flat plate to increase the flexibility of moving objects.

[0018] In the present invention, since two reducers and two drive motors are respectively provided, and each of the reducers and drive motors is respectively located on the corresponding end frame, the drive source can be increased according to the weight of the object. When the object is lighter, a single drive source can be used for driving, and when the object is heavier, two drive sources can be used for driving, which meets the use conditions while reducing energy consumption, and the transport vehicle should not be used when one is damaged.
