Description

Technical Field

[0001] This invention relates to the field of bidirectional shuttle technology, and more particularly to a track-type heavy-duty bidirectional shuttle. Background Technology

[0002] The rail-mounted heavy-duty bidirectional shuttle is an automated device used in modern logistics warehousing and industrial material handling. It uses a fixed track as its travel path and has a heavy load capacity of several tons to tens of tons. It can travel flexibly in both directions along the track. It is mainly used for the storage, retrieval and transfer of goods in high-density racking areas or specific work areas. Through an automated control system, it completes precise positioning, path planning and autonomous operation, which can effectively improve the utilization rate of warehouse space and the turnover efficiency of heavy-duty materials, reduce manual intervention, and is widely applicable to scenarios in manufacturing, cold chain, ports and bulk commodity warehousing where there is a need for efficient and stable handling of heavy-duty materials.

[0003] A search revealed Chinese patent publication number CN212607329U, which discloses a bidirectional rail shuttle vehicle, including a base and a carriage. A rail body is mounted on the upper end of the base, and a support base is connected to the upper end of the rail body. The support base includes a support leg body, a first rotating shaft, a gear, a motor, a mounting plate, a platform, rollers, and a second rotating shaft. The first rotating shaft passes through the center of the support leg body, and a gear is fitted to the outer wall of the first rotating shaft. A motor is connected to the end of the first rotating shaft. This bidirectional rail shuttle vehicle features a first rotating shaft, with a keyed connection between the first rotating shaft and the motor, and a meshing connection between the rail body and the gear. After the user starts the motor, the motor drives the gear to rotate via the first rotating shaft, forming a meshing transmission between the gear and the rail body. This gear drives the support leg body and the carriage to move linearly along the rail body. When the device reaches its destination, the motor rotates in the opposite direction, and the device moves in reverse along the rail body under the drive of the gear. However, in the prior art, due to rail settlement or shelf installation deviations, goods may become stuck, leading to difficulties in storage and retrieval, thus reducing work efficiency. Utility Model Content To overcome the above shortcomings, this utility model provides a track-type heavy-duty bidirectional shuttle, which aims to improve the problem in the prior art that the goods are stuck and difficult to store and retrieve due to track settlement or shelf installation deviation, thereby reducing work efficiency.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a track-type heavy-duty bidirectional shuttle vehicle, comprising a movable shell, a wedge lifting mechanism at the bottom of the movable shell for lifting the device, a lifting motor mechanism at the bottom of the wedge lifting mechanism for charging the device, and an outer frame mechanism for protection of the device on the left side of the wedge lifting mechanism; the wedge lifting mechanism includes a first linear guide rail, which is installed on the bottom right side of the movable shell, a left-hand screw is installed at the rear of the first linear guide rail, a first bearing seat is provided at the bottom of the left-hand screw, a first bearing support pad is fixedly connected to the rear side of the first bearing seat, and a direct-drive wedge block is installed on the top left side of the first bearing support pad.

Since the direct-drive wedge block 205 is connected to the second bearing support pad 206 and is connected to the right-hand lead screw 212 through the installation of the lead screw nut 217, the right-hand lead screw 212 is connected to the lifting base plate 213 at its bottom and to the second linear guide rail at its top through the end reinforcing rib 211. The lower limit sensor 210 is connected to the upper limit sensor 209. The wide reinforcing beam 214 on the front side of the end reinforcing rib 211 further enhances the structural stability. When the direct-connect wedge block 205 moves, it moves along the first linear guide rail 201 and the second linear guide rail 209, pushing the lifting beam 216 to rise and fall, thereby driving the lifting base plate 213 to realize the overall lifting and falling of the device. During the lifting and falling process, the sensor sensing plate 208 moves with the components. When the lower limit sensor 210 is triggered, the device stops falling; when the upper limit sensor 215 is triggered, the device stops rising. Through the above process, the lifting and falling effect of this device is achieved.

The installation of the large battery module 14 facilitates the power supply of the device.

[0032] Working principle: Power is transmitted via the sprocket 219. Under the guidance of the chain guide component 220, the left-hand screw 202 rotates. The bottom of the left-hand screw 202 is stably supported by the first bearing seat 203 and the first bearing support pad 204, which drives the direct-drive wedge block 205 to move. Since the direct-drive wedge block 205 is connected to the second bearing support pad 206, it is transmitted to the right-hand screw 212 through the installation of the screw nut 217. The bottom of the right-hand screw 212 is connected to the lifting base plate 213, and its top is reinforced by the end rib 211. Connected to the second linear guide 209 and the lower limit sensor 210, the wide reinforcing beam 214 on the front side of the end reinforcing rib 211 enhances the structural stability. When the direct-connect wedge active block 205 moves, it moves along the first linear guide 201 and the second linear guide 209, pushing the lifting beam 216 to rise and fall, thereby driving the lifting base plate 213 to realize the overall lifting and falling of the device. During the lifting and falling process, the sensor sensing plate 208 moves with the component. When the lower limit sensor 210 is triggered, the device stops falling, and when the upper limit sensor 215 is triggered, it stops rising, thus realizing the lifting and falling of this device. The outer frame mechanism 3, with the welded structure 312 of the vehicle body as its core frame, plays a protective role during operation. Through the installation of multiple fixed bearing seats 313, it provides stable support for the shuttle's transmission components, reducing vibration and wear during operation. Through the installation of the anti-collision structure 314, it can promptly buffer impact forces in case of collision risk when the shuttle is traveling or parked, preventing damage to the vehicle body and internal components. Through the installation of the display screen 315, it displays the shuttle's operating parameters in real time, facilitating operator monitoring of the equipment status. Through the installation of the pallet sensor frame 304 and the obstacle sensor frame 303, the device can detect obstacles in the travel path and pallet operation area in real time during pallet handling operations, ensuring the safety of the pallets. The operation is safe and precise. Through the installation of the charging structure 305 and the lifting motor mechanism 4, a stable structural support and connection interface can be provided for the charging operation when the shuttle needs to be charged, ensuring stable charging. Through the installation of the rescue structure 306, it is convenient for staff to carry out rescue when the shuttle malfunctions and cannot operate normally. Through the installation of the protective laser structure 307, when a foreign object enters the area, it can trigger an early warning in time, improving operational safety. Through the installation of the bearing bushing 311 and the first wheel chain tensioning plate 310, the tension of the wheel chain can be adjusted, making the device operate more stably. Through the above procedures, when the device has an abnormality, it will automatically disconnect the circuit to avoid damage to the equipment due to circuit failure and ensure overall operational safety.
