Description

Technical Field

[0002] In aisle-based logistics storage systems, a significant portion of these systems utilize RGV shuttles as the primary transport equipment. Most RGVs are roller-based transport devices that reciprocate along rail-guided aisles. Equipped with a loading platform, the RGVs, controlled by an electronic control system, utilize sensors to precisely locate the platform at each storage location within the aisle, enabling both inbound and outbound storage and tallying operations.

[0003] Current RGV shuttles are expensive. Deploying one RGV for each floor and each row of aisles would inevitably result in excessive costs and low utilization rates for many shuttles, leading to idleness and waste. When using only RGVs, elevators are required to lift them to different floors. However, conventional elevators are primarily designed for transporting cargo with carriers and are not suitable for RGV transport. Therefore, there is an urgent need to design an RGV floor-changing elevator to address these issues. Utility Model Content

Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] The utility model provides Figure 1-9 The RGV layer-changing elevator shown in FIG. 1 includes:

[0032] The hoist frame 100 has a guide rail 101 and a guide rail 2 102 on one side of the vertical pole of the hoist frame 100. There are two guide rails 101 and four guide rails 102. Both the guide rails 101 and the guide rails 2 102 are arranged parallel to the vertical pole of the hoist frame 100.

[0033] The lifting mechanism 200 includes a lifting motor 201, a transmission shaft 202, a sprocket seat 203, and a counterweight 205. The sprocket seat 203 is meshed with a chain 207. The counterweight 205 is arranged on one side of the lifting machine frame 100. One end of the chain 207 is fixedly connected to the counterweight 205. The four corners of the counterweight 205 are fixed with guide shoes 1 208 that are slidably connected to the guide rail 101. The lifting motor 201 drives the sprocket on the sprocket seat 203 to rotate, thereby driving the chain 207 to move, so that the chain 207 drives the counterweight 205 to move along the guide rail 101.

[0034] The lifting car 300 includes a car frame 301 arranged inside the hoist frame 100. Chain link rods 302 are fixed at the four corners of the car frame 301. The other end of the second chain 207 is fixedly connected to the chain link rod 302. The counterweight block 205 can offset part of the gravity of the car frame 301, so that the lifting motor 201 can easily complete the lifting operation. The upper and lower ends of the chain link rod 302 are fixed with guide shoes 303 slidably connected to the guide rail 102 to ensure that the car frame 301 moves along the guide rail 102 during the lifting process, which can effectively prevent shaking. The top of the car frame 301 is provided with an RGV track 304 for convenient docking with the RGV trolley 400.

[0035] The RGV trolley 400 is rollingly connected to the RGV track 304 .

[0036] For example, see Figure 1 As shown, the hoist frame 100 is a rectangular parallelepiped frame structure, and fences 103 are fixed on both sides of the hoist frame 100.

[0037] In this technical solution, the fences 103 on both sides of the elevator frame 100 can prevent debris from falling in and prevent goods from falling, thereby improving safety.

[0038] For example, see Figure 1 、 Figure 3 and Figure 4 As shown, the lifting motor 201, the transmission shaft 202 and the sprocket seat 203 are arranged on the top of the lifting machine frame 100, the lifting motor 201 and the sprocket seat 203 are connected to each other through a chain 206, and the two sprocket seats 203 are connected to the transmission shaft 202 through a coupling 204.

[0039] In this technical solution, there are four sprocket seats 203, which are respectively arranged at the four corners of the top of the elevator frame 100 and are arranged one-to-one with the four chain link rods 302. The lifting motor 201 transmits power to one of the sprocket seats 203 through the sprocket and chain 1 206. The sprocket seat 203 drives the other sprocket seat 203 on the same side to move synchronously through the transmission shaft 202 and the coupling 204. The two sprocket seats 203 on the adjacent side are connected by chain 2 207, so that the lifting motor 201 can transmit power to the four sprocket seats 203 at the same time, thereby driving the car frame 301 to rise and fall smoothly.

[0040] For example, see Figure 9 As shown, the counterweight block 205 includes a counterweight frame 2051 and a plurality of counterweight plates 2052 movably nested in the counterweight frame 2051 . A limiting plate 2053 is provided on the inner side of the counterweight frame 2051 , and a through opening 2054 is provided on the top of the limiting plate 2053 .

[0041] In this technical solution, it is convenient to add a counterweight plate 2052 into the counterweight frame 2051 through the through opening 2054 , or to take out the counterweight plate 2052 in the counterweight frame 2051 through the through opening 2054 , so as to adjust the mass of the counterweight block 205 .

[0042] For example, see Figure 4-Figure 6 As shown, a busbar 305 parallel to the RGV track 304 is provided on the top of the car frame 301 .

[0043] In this technical solution, the busbar 305 can connect the power supply and the RGV trolley 400 together to facilitate the transmission of electrical energy and signals. In addition, the busbar 305 can greatly reduce the size and weight of the equipment, improve the equipment's utilization efficiency, reduce maintenance costs, and effectively avoid problems such as electrical isolation and electrical interference.

[0044] For example, see Figure 8As shown, a driving wheel 401 and a driven wheel 402 are respectively provided at both ends of the RGV trolley 400. Both sides of the driving wheel 401 and the driven wheel 402 are provided with limiting wheels 403 that fit with the RGV track 304. One end of the RGV trolley 400 is provided with a driving motor 404 that is transmission-connected to the driving wheel 401.

[0045] In this technical solution, the driving motor 404 drives the driving wheel 401 to rotate, providing power support for the operation of the RGV trolley 400, and the limiting wheel 403 can limit the operation of the RGV trolley 400 to prevent it from falling off the RGV track 304.

[0046] For example, see Figure 7 As shown, a chain conveyor 405 and a second drive motor 406 are provided on the top of the RGV trolley 400 , and the chain conveyor 405 is in transmission connection with the second drive motor 406 .

[0047] In this technical solution, the second drive motor 406 can provide power support for the operation of the chain conveyor 405. The conveying direction of the chain conveyor 405 is perpendicular to the travel direction of the RGV trolley 400, which is convenient for input and output of goods.

[0048] For example, see Figure 1 、 Figure 3 and Figure 7 As shown, an electric control box 407 is provided at both ends of the RGV trolley 400 , and an anti-collision block 408 and a function button 409 are provided on one side of the electric control box 407 .

[0049] In this technical solution, it is convenient to input control instructions through the function button 409, and then the electric control box 407 uniformly controls the coordinated operation of various electrical appliances. The anti-collision block 408 can prevent the RGV trolley 400 from being damaged by collision during operation.

[0050] Working principle: When the RGV floor-changing elevator is used, the warehouse control system first issues a command, and the RGV trolley 400, driven by the drive motor 1 404, moves from the track to the elevator entrance, and then starts the lifting motor 201. The lifting motor 201 drives the car frame 301 up and down through the chain 207. The elevator delivers the elevator car 300 to the system-specified docking layer and exchanges information in real time. When the elevator car 300 stops steadily, the RGV trolley 400 runs into the elevator car 300, and then the elevator delivers the RGV trolley 400 to the system-specified floor. The RGV floor-changing elevator has an advanced design, compact structure, easy use and reliable operation. By fixing the RGV track 304 on the lifting car 300, the RGV trolley 400 can be transported smoothly, and the RGV trolley 400 is transported to the designated floor through the lifting mechanism 200. It is suitable for a mode where the traffic volume is not large and one RGV trolley 400 is used for multiple floors. By setting the guide shoe 1 208 and the guide shoe 2 303, the lifting and transportation can be stable and reliable.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
