Description

Technical Field

[0001] The utility model relates to the technical field of four-way vehicles, in particular to a four-way vehicle which is convenient for accurate positioning and loading and unloading. Background Art

[0002] With the rapid development of the logistics and warehousing industry, the requirements for the handling and storage efficiency of goods in warehouses are getting higher and higher. Although traditional handling equipment such as forklifts and stackers can meet basic handling needs, they often have problems such as difficulty in operation and low efficiency when facing complex and changeable warehouse environments. In addition, forklifts and stackers occupy a large space and cannot be transported in a portable manner.

[0003] In order to solve the above problems, four-way vehicles came into being. The four-way vehicle, also known as the four-way shuttle vehicle, is a highly automated handling equipment that can realize automatic storage and retrieval of goods, automatic lane and layer changing, and automatic climbing, and can transport and travel on the ground. With the development of intelligence, the four-way vehicles currently used in warehouses have the ability to automatically move to the bottom of the shelf and find the correct position, and after aligning with the shelf, they can lift and transfer.

[0004] This type of four-way vehicle usually includes a central controller, a sensor interface, a wireless communication module, etc., which are used to receive operating instructions, process sensor data, and control the operation of motors and other equipment. The central controller calculates the moving path of the four-way vehicle and the grabbing position of the fork arm according to the operating instructions and sensor data, and realizes the movement of the four-way vehicle and the loading and unloading of goods through motors and other equipment. At the same time, it controls the sensors on the four-way vehicle to correspond to the sensors on the shelves to complete accurate alignment operations.

[0005] However, when this type of four-way vehicle is in use, it generally only relies on the lifting platform on the top to complete the lifting operation. Due to the limited area of ​​the lifting platform, the contact area between the lifting platform and the external shelf is also limited. If the center of gravity of the shelf is exactly at its center, the lifting platform can stably support the shelf after lifting it. However, if there are many items on the shelf and the overall center of gravity of the shelf has deviated from its center, the four-way vehicle continues to support the bottom of the shelf. Due to the small support area of ​​the lifting platform and the unstable support, the shelf will overturn due to the shift of the center of gravity, affecting the use effect. In view of this, we propose a four-way vehicle that is easy to accurately position and load. Utility Model Content

[0028] See also Figure 1-Figure 6 The utility model provides a technical solution: a four-way vehicle that is convenient for accurate positioning and loading and unloading, including a four-way vehicle robot body 1, a corresponding infrared sensor is arranged on the four-way vehicle robot body 1, and a corresponding infrared sensor is generally arranged at the bottom of the shelf, or a corresponding sensor is installed on the ground in the warehouse, one of the infrared sensors is a receiver, and the other infrared sensor is a transmitter, so that the four-way vehicle robot body 1 moves until the receiver can receive the transmission signal of the transmitter, which proves that it has been accurately positioned, such as the receiver on the four-way vehicle robot body 1 receives the transmitter at the bottom of the shelf or receives the transmitter signal on the ground to prove that it has been positioned, and then the loading and unloading operation is performed, and the four-way vehicle robot body 1 and the infrared sensor are both existing conventional technologies, which will not be repeated here;

[0029] Specifically, two symmetrical assembly chambers 10 are arranged in the main body 1 of the four-way vehicle robot, and the top of the assembly chamber 10 is connected to the outside. A lifting component 2 is arranged on the main body 1 of the four-way vehicle robot, and the lifting component 2 includes an electric push rod 20 fixedly installed on the bottom wall of the assembly chamber 10, and a storage guide rail 21 is fixedly installed at the end of the telescopic shaft of the electric push rod 20. The storage guide rail 21 is provided with two upper and lower symmetrical and horizontally arranged slide grooves 211, and a slide bar 23 is slidably connected in the slide groove 211. A plurality of gear teeth 231 arranged linearly and evenly spaced are fixedly installed on the sides of the upper and lower slide bars 23 that are close to each other, and a servo motor 24 is fixedly installed on the side of one of the storage guide rails 21. The servo motor 2 A long shaft 25 is fixedly installed at the end of the output shaft of 4, and two front and rear symmetrical gears 26 are fixedly installed on the long shaft 25. The gear 26 is located between the upper and lower slide bars 23 and meshes with the gear teeth 231. An end support rod 27 is fixedly installed at the end of the slide bar 23, and a support plate 271 is fixedly installed at the top of the end support rod 27. The support plate 271 is used for supporting operation to ensure that when in use, the servo motor 24 can be used to drive the slide bar 23 to move outward, so that the area between the four support plates 271 is increased, and the support plate 271 is further used to support the bottom of the shelf, which can play a stable support effect, so that the center of gravity of the shelf can be in the area between the four support plates 271, to ensure that it is not easy to tip over.

[0030] In this embodiment, two symmetrical guide sleeves 22 are fixedly installed on the bottom wall of the assembly chamber 10, and two symmetrical guide columns 221 are fixedly installed on the bottom surface of the storage guide rail 21. The guide columns 221 are located in the guide sleeves 22 and are slidably connected to the guide sleeves 22, so that the storage guide rail 21 is more stable and smooth when moving up and down.

[0031] Specifically, the cross-sections of the slide groove 211 and the slide bar 23 are both T-shaped, and the size of the slide bar 23 matches the size of the slide groove 211 , so that the slide bar 23 can stably move in the slide groove 211 .

[0032] Furthermore, the four support plates 271 are located on the same horizontal plane for simultaneous supporting operations.

[0033] In addition, an anti-skid pad 281 is provided on the support plate 271, and the anti-skid pad 281 is used for anti-skid protection operation to make the support more stable.

[0034] It is worth mentioning that a fixing plate 28 is fixedly installed at the bottom of the anti-slip pad 281, and the fixing plate 28 is fixedly installed on the upper surface of the support plate 271 by multiple fastening screws, which is convenient for fixing and installing the anti-slip pad 281. At the same time, it is convenient to replace the anti-slip pad 281 after it is damaged.

[0035] When the four-way vehicle of the utility model is used, which is convenient for accurate positioning and loading and unloading, the servo motor 24 is connected to the external power supply and made to work. When the servo motor 24 works, the output shaft thereon rotates to drive the gear 26 to rotate. When the gear 26 rotates, the gear 26 and the gear teeth 231 are meshed with each other, so that the slide bar 23 can be driven to move. After the slide bar 23 moves outward to a suitable length, the area between the four support plates 271 increases, and the electric push rod 20 is started and made to work. When the electric push rod 20 works, the telescopic shaft thereon extends to drive the support plate 271 to support on the bottom surface of the shelf, so that the center of gravity of the entire shelf is located in the area between the four support plates 271, and then the transfer operation is carried out. After being transferred to the corresponding position, the electric push rod 20 is started and made to work, and the telescopic shaft thereon is shortened. At this time, the supporting part of the shelf can continue to be normally supported on the ground, and the loading and unloading and transfer operations are completed.
