Description

Technical Field

[0001] The invention relates to the technical field of logistics warehousing, and in particular to a heavy-load, lightweight four-way shuttle vehicle. Background Art

[0002] With the development of science and technology, the storage and retrieval business types of logistics warehousing centers are becoming more and more diversified and complicated. The reciprocating two-way shuttle vehicles of traditional automated warehouses can hardly meet all the growing requirements of warehousing density, low cost and customized needs. There is an urgent need for faster, more flexible, low-cost, high-efficiency and highly information-integrated equipment to fill the blank areas of two-way shuttle vehicles.

[0003] Currently, the four-way shuttle vehicles on the market have poor carrying capacity, and their structures mostly use connecting rod lifting mechanisms or hydraulic lifting rod mechanisms for track switching. The connecting rod lifting mechanism is complex, occupies the internal space of the machine body, has high energy consumption, and poor maintainability; the hydraulic lifting rod mechanism is prone to oil leakage and has poor environmental protection; the height of the whole machine is more than 200mm, which leads to a decrease in the overall space occupancy rate of the shelf. Summary of the invention

[0004] The object of the present invention is to provide a heavy-load, lightweight four-way shuttle vehicle to solve the existing problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a heavy-loaded, lightweight four-way shuttle vehicle, comprising a vehicle body, the vehicle body being composed of an upper frame and a lower frame, a straight-moving mechanism being arranged on the outer side of the upper frame, a transverse mechanism being arranged on the lower frame, and a lifting mechanism being arranged between the upper frame and the lower frame, the lifting mechanism lifts the material and drives the transverse mechanism to move downward and contact the lane, while the straight-moving mechanism is lifted upward and loses contact with the original load, prompting the vehicle body to change its travel direction.

[0006] During specific use, the driving mechanism drives the straight-moving mechanism to operate, thereby driving the vehicle body to move straight on the lane. When turning is required, the jacking mechanism can be used to cause the transverse mechanism to move downward and contact the lane, while the straight-moving mechanism is lifted upward. At this time, the transverse mechanism can be used to drive the vehicle body to move laterally, and the jacking mechanism moves upward to lift the material to be transported upward and lose contact with the original load, thereby facilitating the transportation of the material.

[0007] As a further solution of the present invention, a driving mechanism for driving the movement of the transverse mechanism and the straight mechanism is arranged on the vehicle body, and the driving mechanism includes a servo motor, a reduction motor is arranged at the connecting end of the servo motor, and a transmission shaft is arranged at the output end of the reduction motor.

[0008] During specific use, the vehicle body can be driven to move horizontally and vertically through the horizontal mechanism and the vertical mechanism.

[0009] As a further solution of the present invention, the transverse mechanism (4) includes a transverse axis (6), and the straight mechanism (3) includes a vertical axis (7). The transverse axis (6) is parallel to the lower frame (102), and the vertical axis (7) is parallel to the upper frame (101).

[0010] During specific use, the horizontal axis and the vertical axis are provided to facilitate driving the straight-running wheels and the transverse-running wheels to rotate, thereby driving the vehicle body to move.

[0011] As a further solution of the present invention, the horizontal axis includes a first horizontal axis and a second horizontal axis, the vertical axis includes a first vertical axis and a second vertical axis, and a first chain is arranged outside the first horizontal axis and the transmission shaft.

[0012] During specific use, the first chain is used to drive the first horizontal axis to rotate, thereby driving the straight-moving wheel to rotate.

[0013] As a further solution of the present invention, a first bevel gear is provided at one end of the first horizontal axis, a second bevel gear meshing with the first bevel gear is provided at one end of the first vertical axis and the second vertical axis close to the first horizontal axis, a third bevel gear meshing with the second bevel gear is provided at one end of the second horizontal axis close to the first horizontal axis, and a linear wheel is connected to the ends of the first horizontal axis and the second horizontal axis away from each other, and a transverse wheel is connected to the ends of the first vertical axis and the second vertical axis away from each other.

[0014] During specific use, the transmission shaft can be driven to rotate by the servo motor, the first horizontal axis can be driven to rotate by the transmission of the first chain, the second bevel gear can be driven to rotate by the meshing of the first bevel gear and the second bevel gear, thereby driving the first vertical axis and the second vertical axis to rotate, thereby driving the transverse wheel to rotate, so that the vehicle body can move transversely, and the meshing of the second bevel gear and the third bevel gear can drive the third bevel gear to rotate, thereby driving the second transverse axis to rotate, and the rotation of the first transverse axis and the second transverse axis can drive the straight wheel to rotate, so that the vehicle body can move straight, and the same power element can drive the vehicle body to move horizontally and vertically, which is more energy-efficient.

[0015] As a further solution of the present invention, the lifting mechanism includes a synchronous servo motor, a lifting plate is provided on the upper frame, a left-right rotating ball screw is provided at the bottom of the lifting plate, a synchronous belt is provided at the output end of the synchronous servo motor and the outside of the left-right rotating ball screw, and a screw nut is provided on the left-right rotating ball screw.

[0016] During specific use, the synchronous servo motor output end drives the synchronous belt to rotate, thereby driving the left-right rotating ball screw to rotate through the synchronous belt, which is conducive to driving the wedge-shaped slider to move toward or relative to each other on the left-right rotating ball screw through the screw nut.

[0017] As a further solution of the present invention, a wedge-shaped slider is fixedly connected to the screw nut, an upper roller is arranged at the bottom of the lifting plate, a lower roller is fixedly arranged on the lower frame, the upper roller is arranged at the top of the wedge-shaped slider, and the lower roller is arranged at the bottom of the wedge-shaped slider.

[0018] During specific use, the upper roller and the lower roller can be lifted up by the wedge-shaped sliding block.

[0019] As a further solution of the present invention, a first parallel section and a second parallel section are arranged at the top of the wedge-shaped slider, a first climbing section is arranged between the first parallel section and the second parallel section, a third parallel section and a fourth parallel section are arranged at the bottom of the wedge-shaped slider, and a second crawling section is arranged between the third parallel section and the fourth parallel section.

[0020] During specific use, when the upper roller and the lower roller are respectively placed on the second parallel section and the fourth parallel section, the straight-running wheel contacts the laneway, so that the vehicle body can move straight. When the wedge-shaped slider moves relative to each other, the upper roller gradually enters the first crawling section, while the lower roller is still in the fourth parallel section. At this time, the upper roller and the lifting plate on its top gradually rise to lift the material, which is convenient for material transportation. As the wedge-shaped slider continues to move, the upper roller enters the first parallel section, and the lower roller enters the second crawling section. At this time, the lifting plate maintains stability after rising, and the lower roller can drive the lower frame to move downward under the extrusion of the second crawling section, thereby driving the transverse wheel to move downward and contact the laneway, and the straight-running wheel is lifted upward. At this time, the vehicle body can move laterally through the transverse wheel. Through this structure, the vehicle body can move laterally and vertically, and the operation is convenient, and the material can be lifted upward and stabilized through the lifting mechanism.

[0021] The heavy-loaded, lightweight four-way shuttle vehicle described in the present invention enables the lower roller to enter the second crawling section through the relative movement of the wedge-shaped slider. At this time, the jacking plate maintains stability after rising, and the lower roller can drive the lower frame to move downward under the extrusion of the second crawling section, thereby driving the transverse wheel to move downward and contact the lane, and the straight wheel is pushed upward, and the vehicle body can move laterally through the transverse wheel. Through this structure, the vehicle body can move laterally and vertically, and the operation is convenient, and the material can be pushed upward and stabilized through the jacking mechanism. This device can travel in multiple directions and operate across lanes, which is more efficient and flexible, is not restricted by space, and can make full use of space. In addition, by adopting a screw slider mechanism instead of a connecting rod structure or a hydraulic jack mechanism, the dead weight and vehicle body height are reduced, the internal structure of the vehicle body is simplified, and problems such as liquid leakage are eliminated. At the same time, a higher load-bearing capacity is obtained. In addition, the power in two directions of the straight mechanism and the transverse mechanism only uses one driving motor, which simplifies the internal structure of the vehicle body, reduces the manufacturing cost, and is conducive to energy conservation and emission reduction.

[0031] When in use, the driving mechanism 5 drives the straight-moving mechanism 3 to operate, thereby driving the vehicle body 1 to move straight on the lane. When turning is required, the jacking mechanism 2 can cause the transverse mechanism 4 to move downward and contact the lane, while the straight-moving mechanism 3 is lifted upward. At this time, the transverse mechanism 4 can drive the vehicle body 1 to move horizontally, and the jacking mechanism 2 moves upward to lift the material to be transported upward and lose contact with the original load, thereby facilitating the transportation of the material.

[0033] Further, the horizontal axis 6 includes a first horizontal axis 601 and a second horizontal axis 602, the vertical axis 7 includes a first vertical axis 701 and a second vertical axis 702, the first horizontal axis 601 and the transmission shaft 501 are both provided with a first sprocket on the outside, the first sprocket is provided with a first chain 8 on the outside, one end of the first horizontal axis 601 is provided with a first bevel gear 9, one end of the first vertical axis 701 and the second vertical axis 702 close to the first horizontal axis 601 is provided with a second bevel gear 10 meshing with the first bevel gear 9, and one end of the second vertical axis 701 and the second vertical axis 702 close to the first horizontal axis 601 is provided with a second bevel gear 10 meshing with the first bevel gear 9. The third bevel gear 11 is meshed with the two bevel gears 10, and the ends of the first transverse axis 601 and the second transverse axis 602 that are away from each other both penetrate the vehicle body 1 and extend to the outside of the vehicle body 1. The ends of the first transverse axis 601 and the second transverse axis 602 that extend to the outside of the vehicle body 1 are connected to the straight-running wheels 12. The number of the straight-running wheels 12 is set to be multiple, and the multiple straight-running wheels 12 are driven by the second chain 13, and the ends of the first vertical axis 701 and the second vertical axis 702 that are away from each other are connected to the transverse wheels 14, and two adjacent transverse wheels 14 are connected by the third chain 15.

[0034] When in use, the transmission shaft 501 can be driven to rotate by the servo motor, the first horizontal axis 601 can be driven to rotate by the transmission of the first chain 8, the second bevel gear 10 can be driven to rotate by the engagement of the first bevel gear 9 with the second bevel gear 10, thereby driving the first vertical axis 701 and the second vertical axis 702 to rotate, thereby driving the transverse wheel 14 to rotate, so that the vehicle body 1 can move transversely, and the engagement of the second bevel gear 10 with the third bevel gear 11 can drive the third bevel gear 11 to rotate, thereby driving the second transverse axis 602 to rotate, and the rotation of the first transverse axis 601 and the second transverse axis 602 can drive the straight wheel 12 to rotate, so that the vehicle body 1 can move straight, and the same power element can drive the vehicle body 1 to move in the transverse and vertical directions, which is more energy-efficient.

[0035] like Figure 3-6 As shown, the lifting mechanism 2 includes a synchronous servo motor, a lifting plate 201 is provided on the upper frame 101, a vertical shaft is fixedly provided at the bottom of the lifting plate 201, and the vertical shaft is slidably connected to the upper frame 101, a left-right rotating ball screw 202 is provided at the bottom of the lifting plate 201, a synchronous pulley is provided at the output end of the synchronous servo motor and the outer side of the left-right rotating ball screw 202, a synchronous belt 203 is provided at the outer side of the synchronous pulley, a screw nut is provided on the left-right rotating ball screw 202, a wedge-shaped slider 204 is fixedly connected to the screw nut, an upper roller 205 is provided at the bottom of the lifting plate 201, and a lower roller 206 is fixedly provided on the lower frame 102, the upper roller 205 is arranged at the top of the wedge-shaped slider 204, and the lower roller 206 is arranged at the bottom of the wedge-shaped slider 204;

[0036] Furthermore, a first parallel section 207 and a second parallel section 208 are provided at the top of the wedge-shaped slider 204, a first climbing section 209 is provided between the first parallel section 207 and the second parallel section 208, a third parallel section 210 and a fourth parallel section 211 are provided at the bottom of the wedge-shaped slider 204, and a second crawling section 212 is provided between the third parallel section 210 and the fourth parallel section 211.

[0037] When in use, the synchronous belt 203 is driven to rotate through the output end of the synchronous servo motor, thereby driving the left-right rotating ball screw 202 to rotate through the synchronous belt 203, which is conducive to driving the wedge-shaped slider 204 to move toward or relative to the left-right rotating ball screw 202 through the screw nut. When the upper roller 205 and the lower roller 206 are respectively placed on the second parallel section 208 and the fourth parallel section 211, the straight-running wheel 12 contacts the lane, so that the vehicle body 1 can move straight. When the wedge-shaped slider 204 moves relatively, the upper roller 205 gradually enters the first crawling section, while the lower roller 206 is still in the fourth parallel section 211. At this time, the upper roller 205 and the lifting plate 201 on its top gradually rise to lift the material, which is convenient for the transportation of the material. As the wedge-shaped slider 204 continues to move, the upper roller 205 enters the first parallel section 207, and the lower roller 206 enters the second crawling section 212. At this time, the lifting plate 201 maintains stability after rising. The lower roller 206 can drive the lower frame 102 to move downward under the squeezing of the second crawling section 212, thereby driving the transverse wheel 14 to move downward and contact the tunnel, and the straight wheel 12 is pushed up. At this time, the vehicle body 1 can move laterally through the transverse wheel 14. This structure enables the vehicle body 1 to move laterally and vertically, which is convenient to operate. The material can be pushed upward and stabilized through the lifting mechanism 2. This device can travel in multiple directions and operate across tunnels. It is more efficient and flexible, not restricted by space, and can make full use of space. Compared with other four-way shuttle vehicles, the screw slider mechanism replaces the connecting rod structure or the hydraulic push rod mechanism, which reduces the dead weight and the height of the vehicle body 1, simplifies the internal structure of the vehicle body 1, eliminates problems such as liquid leakage, and obtains a higher load-bearing capacity. In addition, the power in the two directions of the straight mechanism 3 and the transverse mechanism 4 only uses one drive motor, which simplifies the internal structure of the vehicle body 1, reduces the manufacturing cost, and is conducive to energy conservation and emission reduction.

[0038] Working principle: The servo motor can drive the transmission shaft 501 to rotate, and the transmission of the first chain 8 can drive the first horizontal axis 601 to rotate. The meshing of the first bevel gear 9 and the second bevel gear 10 can drive the second bevel gear 10 to rotate, thereby driving the first vertical axis 701 and the second vertical axis 702 to rotate, thereby driving the horizontal wheel 14 to rotate, so that the vehicle body 1 can move horizontally, and the meshing of the second bevel gear 10 and the third bevel gear 11 can drive the third bevel gear 11 to rotate, thereby driving the second horizontal axis 602 to rotate, and the rotation of the first horizontal axis 601 and the second horizontal axis 602 can drive the straight wheel 12 to rotate, so that the vehicle body 1 can move straight, and the synchronous servo motor output end drives the synchronous belt 203 to rotate, thereby driving the left and right rotating ball screw 202 to rotate through the synchronous belt 203, which is conducive to driving the wedge slider 204 on the left and right rotating ball screw 202 to move toward or relative to each other through the screw nut. When the upper roller 205 and the lower roller 206 are placed on the second parallel section 208 and the fourth parallel section 211 respectively, the straight wheel 12 contacts the lane, so that the vehicle body 1 can move straight. When the wedge-shaped slider 204 moves relatively, the upper roller 205 gradually enters the first crawling section, while the lower roller 206 is still in the fourth parallel section 211. At this time, the upper roller 205 and the lifting plate 201 on its top gradually rise to lift the material, which is convenient for the transportation of the material. As the sliding block 204 continues to move, the upper roller 205 enters the first parallel section 207, and the lower roller 206 enters the second crawling section 212. At this time, the lifting plate 201 maintains stability after rising, and the lower roller 206 can drive the lower frame 102 to move downward under the squeezing of the second crawling section 212, thereby driving the transverse wheels 14 to move downward and contact the lane, while the straight wheels 12 are lifted upward. At this time, the vehicle body 1 can move laterally through the transverse wheels 14.
