Description

Technical Field

[0001] The utility model relates to the technical field of warehousing and logistics equipment, in particular to a symmetrical walking transmission mechanism of a four-way shuttle vehicle. Background Art

[0002] With the rapid popularization of automated stereoscopic warehouses in my country, higher requirements have been put forward for the safety, integration, operation efficiency, and comprehensive cost of warehouse automation equipment. The four-way shuttle is a new type of automated storage equipment that integrates the functions of the traditional mother car and the child car, and realizes the functions of two cars with one car. As a new automated storage and transportation equipment, the four-way shuttle system has gradually entered people's field of vision. As an upgrade of the two-way shuttle technology, the four-way shuttle system can realize four-way travel in the X and Y directions, and can operate efficiently and flexibly across the aisles. It has the advantages of high cost performance, high storage density, and high warehouse utilization.

[0003] The existing four-way shuttle vehicles are mostly of the following two types: 1) Multi-motor transmission: The travel direction is driven by two motors separately, which cooperate with the reducer and are connected to the travel shaft through a chain. When the motor rotates, the travel wheel rotates; 2) Single motor chain transmission: Through a reducer with a sprocket, the power of the motor is divided into two transmission powers. The sprocket of the reducer transmits the power to the X-axis, and the output end of the reducer transmits the power to the Y-axis through the chain.

[0004] However, the above-mentioned four-way shuttle has the following problems when in use: multi-motor transmission: high cost; low space utilization; single motor chain transmission: the output end of the reducer with a sprocket needs a set of sprocket transmission devices to transmit power to the walking wheel, and the structure is complicated. Therefore, a single-motor, low-cost, and simple-structured four-way shuttle is needed. Summary of the invention

[0005] The utility model proposes a symmetrical travel transmission mechanism for a four-way shuttle vehicle in view of the problems that the current four-way shuttle vehicle adopts multi-motor transmission, which has high cost and low space utilization, and single-motor chain transmission, in which the output end of the reducer with a sprocket needs to have a set of sprocket transmission devices to transmit power to the travel wheels, and the structure is complicated.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a symmetrical walking transmission mechanism of a four-way shuttle vehicle, including a casing, a servo motor is installed inside the casing, the output end of the servo motor is connected to a reducer, the reducer is provided with an output sprocket and two output ends, the output sprocket of the reducer is transmission-connected with a longitudinal chain, the casing is rotationally connected with a longitudinal axis, the longitudinal chain is transmission-connected with the longitudinal axis, the two ends of the longitudinal axis are connected with longitudinal wheels, the two output ends of the reducer are connected with a coupling, one end of the coupling is connected with a transverse axis, the transverse axis is rotationally connected to the casing, the transverse axis is connected with a transverse wheel, the transverse wheels on one side of the casing are transmission-connected by a transverse wheel chain, and when in use When the shuttle is moved, the servo motor provides power, the torque is increased by the reducer, the output sprocket on the reducer drives the longitudinal chain to rotate, the longitudinal chain drives the longitudinal axis to rotate, the longitudinal axis drives the longitudinal wheel to rotate, and the longitudinal axis drives the longitudinal wheel to rotate, so as to realize the longitudinal movement of the shuttle, the coupling connected to the two output ends of the reducer drives the transverse axis to rotate, the transverse axis drives the transverse wheel chain, and the transverse wheel chain drives the transverse wheel to rotate, so as to realize the transverse movement of the shuttle. The shuttle adopts a single drive motor with low overall cost. At the same time, the three output ends of the reducer can realize the longitudinal and transverse movement of the shuttle. The structure is simple, the use effect is good, the practicability is strong, and it is suitable for popularization and use.

[0007] Furthermore, there are two longitudinal wheels, and the two longitudinal wheels are connected via a longitudinal wheel chain transmission.

[0008] Furthermore, a battery and an electronic control component are installed inside the housing, the battery provides power to the servo motor, and the electronic control component controls the movement of the shuttle.

[0009] Furthermore, the battery and the electronic control assembly are respectively located on both sides of the servo motor.

[0010] Furthermore, the transverse wheels and the longitudinal wheels are arranged symmetrically.

[0011] Furthermore, the coupling adopts a universal coupling.

[0012] The beneficial effects of the utility model are:

[0013] The symmetrical travel transmission mechanism of the four-way shuttle vehicle has a compact structure, reduced weight of the whole machine, and reduced manufacturing cost. It adopts servo motor, chain and universal coupling for transmission, has high speed, adopts symmetrical layout, simple travel power transmission chain, low failure rate and simple maintenance.
