Description

Technical Field

[0001] The invention relates to the technical field of storage equipment, and in particular to a four-way shuttle vehicle. Background Art

[0002] The four-way shuttle is an intelligent shuttle transport equipment that integrates the functions of four-way travel, on-site track change, automatic transport, intelligent monitoring and dynamic traffic management.

[0003] Common examples in existing vehicle technology and mechanical solutions include:

[0004] The hydraulic jacking shuttle car will have reduced sealing performance after long-term use, causing pollution to the car body and the cargo space in the vertical warehouse, resulting in unnecessary losses to customers; the common cam jacking and rack and pinion jacking shuttle cars are difficult to assemble and maintain and have high energy consumption. At the same time, each reversing mechanism is controlled by a separate control mechanism, resulting in more internal parts of the shuttle car and lower space utilization inside the shuttle car. During the reversing process, the transmission process is more complicated. At the same time, the internal structure of the shuttle car leads to internal structural instability, which reduces the working efficiency of the four-way shuttle car.

[0005] Therefore, it is necessary to provide a novel four-way shuttle to solve the above problems in the prior art. Summary of the invention

[0006] The purpose of the present invention is to provide a four-way shuttle vehicle for use in the field of storage equipment technology. Compared with similar products, it is simpler. From a design perspective, it has simple transmission, stable structure, and higher efficiency. From an economic perspective, it has low cost and high efficiency and is more marketable.

[0007] To achieve the above object, the technical solution of the present invention is as follows:

[0008] A four-way shuttle vehicle, comprising:

[0009] A frame body, wherein a first wheel set is movably provided on a side wall of the frame body;

[0010] A lifting plate, movably arranged on the frame body, a side wall of the lifting plate movably arranged with at least two first control rods of the second wheel set, and the first control rods are rotatably arranged on the frame body;

[0011] At least two reversing mechanisms are arranged on the same first control rod, and the reversing mechanisms are respectively connected to the lifting plate and the frame body;

[0012] The rotation of the first control rod drives the two reversing mechanisms to move away from or approach each other, so that the frame body and the lifting plate move away from or approach each other, and the second wheel set or the first wheel set contacts the ground, thereby changing the movement direction of the four-way shuttle.

[0013] By adopting the above technical solution, the first control rod drives the two reversing mechanisms to move during the movement, so that the lifting plate and the frame body can move away from or closer to each other. At the same time, since the second wheel group is arranged on the side wall of the lifting plate and the first wheel group is arranged on the side wall of the frame body, during use, it is only necessary to drive the first control rod to rotate to realize the reversal of the four-way shuttle vehicle. The overall operation is simple and simpler than similar products. From a design perspective, the transmission is simple, the structure is stable, and the efficiency is higher. From an economic perspective, it is low-cost and high-efficiency, and has a better market.

[0014] Optionally, the reversing mechanism includes a first lifting plate, a second lifting plate and a lifting block, wherein one end of the first lifting plate is rotatably disposed on the top lifting plate, and the other end is rotatably disposed inside the frame body; one end of the second lifting plate is rotatably disposed on the top lifting plate, and the other end is rotatably disposed on the lifting block, and the lifting block is connected to the first control rod;

[0015] In the working state, the first control rod rotates to drive the two lifting blocks to move away from or closer to each other, thereby driving the first lifting plate and the second lifting plate to rotate, so that the lifting plate moves away from or closer to the frame body.

[0016] By adopting the above technical solution, the first lifting plate and the second lifting plate act together on the jacking plate and the frame body to form a scissor-type connecting rod structure. Practice has proved that the scissor-type connecting rod structure is a stable mechanism with simple structure, easy production, good stability during operation, no vibration and looseness, high transmission efficiency, and can also achieve high-speed movement.

[0017] Optionally, the side wall of the first control rod is provided with a first thread segment and a second thread segment, the thread rotation direction of the first thread segment is opposite to that of the second thread segment, and the two lifting blocks are respectively threadedly connected to the first thread segment and the second thread segment.

[0018] By adopting the above technical solution, the present invention adopts the first thread segment and the second thread segment with opposite thread rotation directions, that is, adopts positive and negative screw transmission, reduces the driving torque, accurately pushes the connecting rod to move, and moves quickly. At the same time, sliding bearings are used to reduce friction, reduce energy loss, and operate smoothly.

[0019] Optionally, the first lifting plate and the second lifting plate are both inclined, and the first lifting plate and the second lifting plate are cross-arranged.

[0020] By adopting the above technical solution, the first lifting plate and the second lifting plate are both inclined. During the movement of the first lifting plate and the second lifting plate, due to their inclined setting, during the movement, horizontal or vertical force is applied to the first lifting plate or the second lifting plate, and the movement of the first lifting plate and the second lifting plate will not interfere with each other. At the same time, since the first lifting plate and the second lifting plate are cross-arranged, during the movement of the first lifting plate and the second lifting plate, the movement directions of the first lifting plate and the second lifting plate are opposite, which is convenient for driving the relative movement between the lifting plate and the frame body.

[0021] Optionally, a second control rod is rotatably arranged inside the frame body, both ends of the second control rod are connected to the first control rod, a transmission member is arranged on the frame body, and both the first control rod and the second control rod are connected to the transmission member; the transmission member converts the rotation of the second control rod into the rotation of the first control rod.

[0022] By adopting the above technical solution, the two first control rods are controlled and transmitted by the same second control rod. The rotation of the second control rod can drive the two first control rods to rotate. There is no need to control the two first control rods separately, thereby reducing the number of motors, better optimizing the internal space of the vehicle, and facilitating vehicle assembly and subsequent maintenance and repair.

[0023] Optionally, the transmission member is a right-angle reducer.

[0024] By adopting the above technical solution, the right-angle reducer can make the first control rod and the second control rod arranged vertically, so as to better optimize the interior space of the vehicle, and at the same time can change the force transmission direction without adding additional transmission devices.

[0025] Optionally, a first driving member and a second driving member are movably arranged on the frame body, the first driving member is connected to the first wheel set, and telescopic universal couplings are arranged at both ends of the second driving member, and the telescopic universal couplings are connected to the second wheel set;

[0026] The first driving member rotates to drive the first wheel set to rotate, and the second driving member rotates to drive the second wheel set to rotate through the telescopic universal coupling.

[0027] By adopting the above technical solution, the telescopic universal coupling allows axial movement. The telescopic universal coupling provides greater flexibility when maintaining and replacing transmission components without completely disassembling the transmission system. At the same time, it can compensate for the axial displacement caused by the movement of the lifting plate and the frame body, thereby maintaining the stable operation of the transmission system.

[0028] Optionally, a driving motor is fixedly mounted on the frame body, a reducer is arranged at the rotating shaft of the driving motor, a first transmission belt and a second transmission belt are connected to the reducer, the first transmission belt is connected to the first driving member and is used to drive the first driving member to rotate, and the second transmission belt is connected to the second driving member and is used to drive the second driving member to rotate.

[0029] By adopting the above technical solution, one end of the first transmission belt is sleeved on the first driving member, and a pulley matching the first transmission belt is fixedly provided on the first driving member. One end of the second transmission belt is sleeved on the second driving member, and a pulley matching the second transmission belt is fixedly provided on the second driving member. The driving motor is started to drive the first transmission belt and the second transmission belt to rotate, thereby driving the first driving member and the second driving member to rotate, thereby driving the second wheel group and the first wheel group to rotate. The rotation of the second wheel group and the first wheel group can be synchronously controlled by one motor, and the control method is simple. Compared with using two motors to control separately, the internal space of the vehicle is optimized.

[0030] Optionally, a third transmission belt is provided in the frame body, and the third transmission belt is respectively connected to the first wheel set and the first driving member.

[0031] By adopting the above technical solution, a pulley cooperating with the third transmission belt is provided on the first driving member. The rotation of the first driving member drives the second transmission belt to move, thereby driving the second wheel group to rotate, facilitating the rotation process of the second wheel group.

[0032] Optionally, a fork assembly for picking up objects is provided on the lifting plate.

[0033] By adopting the above technical solution, during the working process, since the lifting plate can move in the vertical direction relative to the ground, it can drive the fork assembly to move in the vertical direction, which is convenient for picking up and placing goods.

[0034] Optionally, a plurality of reinforcing ribs are arranged inside the frame body.

[0035] By adopting the above technical solution, the strength of the vehicle body is enhanced and more cargo can be carried.

[0036] The four-way shuttle provided by the present invention has at least the following beneficial effects:

[0037] 1. The four-way shuttle vehicle provided by the present invention has a body part that is a steel structure component, and the frame component is reasonably inlaid to make its structure stable and reliable; the vehicle is lightweight by reasonably arranging weight-reducing holes, which greatly reduces the weight of the vehicle while meeting the strength requirements, making it more efficient and reasonable; the vehicle is more solid by reasonably arranging reinforcement plates, meeting the strength requirements, and reducing the cost, making the vehicle more cost-effective.

[0038] 2. The reversing mechanism can realize reversing and lifting at the same time, which is convenient for picking up and placing goods, and at the same time controls the second wheel group and the first wheel group to contact the track at different positions to achieve the purpose of four-way movement.

[0039] 3. The reversing mechanism adopts a threaded connection transmission method, which will not vibrate or loosen, has high transmission efficiency, and can also achieve high-speed movement. Here, positive and negative threaded screws are used for transmission to reduce the driving torque, accurately push the connecting rod to move, and move quickly. At the same time, sliding bearings are used to reduce friction, reduce energy loss, and run smoothly;

[0040] 4. The driving motor controls the second wheel group and the first wheel group at the same time, realizing one-wheel drive four-wheel synchronous operation, which is simpler than similar products. From the design point of view, the transmission is simple, the structure is stable, and the efficiency is higher; from the economic point of view, it is low-cost and high-efficiency, and has a better market;

[0041] 5. Controlling the rotation of the first control rod from the end of the first control rod changes the form of placing the control structure in the middle in the prior art. When the first control rod is controlled to rotate from the middle, the first control rod may bend and vibrate due to the long force arm; while controlling from the end can shorten the force arm, reduce such bending and vibration, and improve the stability and accuracy of movement; end control can usually provide better support and fixation, thereby enhancing the rigidity of the entire first control rod, which is particularly critical for applications with heavy loads or high-speed movements; at the same time, end control can reduce energy loss and improve transmission efficiency, because direct control from the end can reduce energy loss caused by intermediate transmission;

[0042] 6. The four-way shuttle in the present invention uses a reduced number of motors, which directly reduces the manufacturing cost of the shuttle, including the purchase cost, installation cost and maintenance cost of the motors; at the same time, the reduction in the number of motors means that the total power consumption of the motors is reduced, thereby reducing the operating energy consumption of the shuttle, which is conducive to energy conservation and emission reduction. The reduction in the number of motors can make the structure of the shuttle simpler, reduce mechanical complexity and potential failure points; the simplified shuttle may have a more optimized power distribution and control system, thereby improving operating efficiency.

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0054] The specific implementation modes of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] Reference Figure 1-8The embodiment of the present invention provides a four-way shuttle vehicle, comprising: a frame body 100, a first wheel group 110 is movably provided on the side wall of the frame body 100, and the first wheel group 110 is rotatably connected to the side wall of the frame body 100 through structures such as bearings and bearing seats, a lifting plate 200 is movably provided on the frame body 100, and a second wheel group 210 is movably provided on the two side walls of the lifting plate 200, and the second wheel group 210 is rotatably connected to the side wall of the lifting plate 200 through structures such as bearings and bearing seats, and the frame body 100 and the lifting plate 200 can move relative to each other in the vertical direction, and at the same time, the axis directions of the second wheel group 210 and the first wheel group 110 are perpendicular to each other, and at least two first control rods 120 are provided on the frame body 100, and the two first control rods 120 are respectively placed on both sides of the frame body 100 and are rotatably connected to the frame body 100 through a rotating shaft, and the two first control rods 1 20 are cylindrical, and a reversing mechanism 130 is arranged on the first control rod 120. One end of the reversing mechanism 130 is connected to the lifting plate 200, and the other end is connected to the frame body 100. The reversing mechanism 130 is used to make the lifting plate 200 and the frame body 100 move away from or close to each other, and at least two reversing mechanisms 130 are arranged on the same first control rod 120. In addition, multiple reversing mechanisms 130 can also be arranged on the same first control rod 120. In this embodiment, two groups of reversing mechanisms 130 are arranged on the same first control rod 120. When the first control rod 120 rotates, the two reversing mechanisms 130 are driven to move in the direction of moving away from or approaching each other, thereby driving the frame body 100 and the lifting plate 200 to move away from or approach each other. In this process, the second wheel group 210 or the first wheel group 110 contacts the track on the ground, thereby changing the movement direction of the four-way shuttle.

[0056] During use, the lifting plate 200 is connected to the frame body 100, and there is a certain gap between the frame body 100 and the ground, which is convenient for the movement of the four-way shuttle. The first wheel group 110 contacts the ground, driving the lifting plate 200 and the frame body 100 to move in a direction perpendicular to the axis of the first wheel group 110. After moving to the designated location, the first control rod 120 is controlled to rotate, driving the reversing mechanism 130 on the first control rod 120 to approach or move away from each other along the first control rod 120, so that the frame body 100 and the lifting plate 200 are close to each other, the second wheel group 210 contacts the ground, and the reversing mechanism 130 continues to move, driving the frame body 100 and the first wheel group 110 to rise, and separating the first wheel group 110 from the ground. At this time, the four-way shuttle moves in a direction perpendicular to the axis of the second wheel group 210.

[0057] Reference Figure 1-8The reversing mechanism 130 includes a first lifting plate 131, a second lifting plate 132 and a lifting block 133. One end of the first lifting plate 131 is rotatably arranged inside the lifting plate 200 through a rotating shaft, and the other end is rotatably arranged inside the frame body 100 through a rotating shaft; one end of the second lifting plate 132 is rotatably arranged on the inner wall of the lifting plate 200 through a rotating shaft, and the other end is rotatably arranged on the lifting block 133 through a rotating shaft. At the same time, the lifting block 133 is connected to the first control rod 120. By rotating the first control rod 120, the lifting block 133 can be driven to move axially along the first control rod 120. In the working state , control the first control rod 120 to rotate, the first control rod 120 rotates to drive the two lifting blocks 133 on the first control rod 120 to move away from or approach each other along the axial direction of the first control rod 120, and at the same time, the first lifting plate 131 and the second lifting plate 132 are both inclined, and the first lifting plate 131 and the second lifting plate 132 are arranged crosswise with each other, and the first lifting plate 131 and the second lifting plate 131 are both inclined. During the movement of the first lifting plate 131 and the second lifting plate 131, due to their inclined arrangement, during the movement, the first lifting plate 131 or the second lifting plate 132 is moved. The lifting plate 131 applies a force in the horizontal or vertical direction, and the movement of the first lifting plate 131 and the second lifting plate 131 will not interfere with each other. At the same time, since the first lifting plate 131 and the second lifting plate 131 are arranged crosswise, during the movement of the first lifting plate 131 and the second lifting plate 131, the movement directions of the first lifting plate 131 and the second lifting plate 131 are opposite, which is convenient for driving the relative movement between the top lifting plate 200 and the frame body 100; the movement of the lifting block 133 drives the first lifting plate 131 and the second lifting plate 132 to rotate around their own axes, and the frame body 100 is rotated during the rotation. The main body 100 moves away from or approaches the lifting plate 200; when the two lifting blocks 133 approach each other, the rotating shaft of the first lifting plate 131 placed on the lifting plate 200 and the rotating shaft of the second lifting plate 132 placed on the lifting plate 200 tend to move away from each other, and at this time the frame main body 100 and the lifting plate 200 approach each other; when the two lifting blocks 133 move away from each other, the rotating shaft of the first lifting plate 131 placed on the lifting plate 200 and the rotating shaft of the second lifting plate 132 placed on the lifting plate 200 tend to move toward each other, and at this time the frame main body 100 and the lifting plate 200 move away from each other, completing the change of movement direction.

[0058] Reference Figure 1-8The first control rod 120 is cylindrical, and the side wall of the first control rod 120 is provided with a thread. The thread of the side wall of the first control rod 120 forms a first thread segment 121 and a second thread segment 122 on the side wall of the first control rod 120. The thread rotation directions of the first thread segment 121 and the second thread segment 122 are opposite. That is, in this embodiment, the first control rod 120 is a positive and negative thread screw. At the same time, the two lifting blocks 133 are respectively threadedly connected to the first thread segment 121 and the second thread segment 122. When the first control rod 120 rotates, the second lifting plate 132 limits the lifting block 133 and hinders the rotation of the lifting block 133, so that the rotation of the first control rod 120 is converted into the movement of the lifting block 133 along the axis direction of the first control rod 120. At the same time, due to a thread Due to the limiting effect of the first threaded segment and the second threaded segment 122, during the rotation of the first control rod 120, the two lifting blocks 133 move in the direction of moving away from or approaching each other; the positive and negative threaded screw can realize efficient power transmission and conversion during the transmission process, thereby improving the operating efficiency of the mechanical equipment; and because it has a strict pitch and thread matching relationship, the first control rod 120 has high positioning accuracy and repeated positioning accuracy, and can ensure the stability of the lifting height of the four-way shuttle car during use; at the same time, since the first control rod 120 adopts the positive and negative threaded screw, this screw can withstand large axial and radial loads and is suitable for various working environments and working conditions; in addition, the first control rod 120 occupies a small space, which is conducive to the miniaturization and compactness of the mechanical equipment.

[0059] Reference Figure 1-8A second control rod 140 is also rotatably arranged in the frame body 100 through a rotating shaft, and both ends of the second control rod 140 are respectively connected to the first control rod 120. The rotation of the second control rod 140 can drive the first control rod 120 to rotate. At the same time, a transmission member 400 is fixedly arranged on the frame body 100, and the ends of the two first control rods 120 are connected to the transmission member 400, and both ends of the second control rod 140 are connected to the transmission member 400. In this embodiment, the axis of the first control rod 120 and the axis of the second control rod 140 are perpendicular to each other, and the transmission member 400 can convert the rotation of the second control rod 140 into the rotation of the first control rod 120. In this embodiment, the transmission member 400 is a right-angle reducer. In the embodiment, two bevel gears are arranged inside the transmission member, and the two bevel gears are meshed with each other. The end of the first control rod 120 is fixedly arranged on one of the bevel gears, and the fixing method thereof can be clamping, welding, bolting, etc. In the present embodiment, a bolt-fixed connection method is adopted. The second control rod 140 is fixedly arranged on the other bevel gear, and the fixing method thereof can be clamping, welding, bolting, etc. In the present embodiment, a bolt-fixed connection method is adopted. The second control rod 140 rotates, driving one of the bevel gears to rotate, thereby driving the other bevel gear to rotate, causing the first control rod 120 to rotate, thereby driving the two lifting blocks 133 to move. A first motor is arranged on the frame body 100, and the axial direction of the rotating shaft of the first motor is aligned with the first motor. The axial directions of the two control rods 140 are the same, and the rotating shaft of the first motor is connected to the second control rod 140 through a pulley; during operation, the first motor is started to drive the second control rod 140 to rotate, and the second control rod 140 drives the two first control rods 120 to rotate through the right-angle reducer, thereby driving the reversing mechanism 130 to move, so that the frame body 100 and the lifting plate 200 move away from or close to each other, and the lifting and reversing can be completed by only one first motor; at the same time, in this embodiment, the transmission member 400 is arranged at the end of the first control rod 120, which changes the form of placing the control structure in the middle in the prior art. When the middle part controls the rotation of the first control rod 120, due to the longer force arm, it may cause The first control rod 120 bends and vibrates; while controlling from the end can shorten the lever arm, reduce such bending and vibration, and improve the stability and accuracy of movement; end control can usually provide better support and fixation, thereby enhancing the rigidity of the entire first control rod 120, which is particularly critical for applications that bear heavy loads or high-speed movements; at the same time, end control can reduce energy loss and improve transmission efficiency, because direct control from the end can reduce energy loss caused by intermediate transmission; in addition, the traditional control method makes it impossible to compress the internal space of the four-way shuttle, and in this embodiment, the transmission member 400 adopts the form of a bevel gear inside, so that the transmission member has almost no top height, which effectively reduces the thickness of the four-way shuttle;Thinner shuttles can reduce the space requirements of the aisles, thereby accommodating more shelves or goods in a limited space, improving storage density, being more suitable for narrow aisles, and being more flexible in different warehouse environments, with strong adaptability; thin shuttles are usually lighter in weight and require less driving energy, which helps reduce energy consumption; at the same time, due to their simpler structure, thin shuttles may be easier to maintain and overhaul. ;

[0060] Reference Figure 1-8The frame body 100 is also movably provided with a first driving member 150 and a second driving member 160, both of which are rod-shaped, wherein the first driving member 150 is connected to the first wheel set 110, and the first driving member 150 rotates to drive the first wheel set 110 to rotate, and both ends of the second driving member 160 are fixedly provided with a retractable universal coupling 161, which can be fixed by clamping, bonding, bolting, etc. In this embodiment, the retractable universal coupling 161 is bolted to the second driving member 160, and the retractable universal coupling 161 is connected to the rotating shaft of the second wheel set 210, so that the second driving member 161 can be fixed to the second wheel set 210. 0 is connected to the second wheel set 210. During the rotation process, the second driving member 160 drives the telescopic universal coupling 161 to move, thereby driving the second wheel set 210 to rotate. When the frame body 100 and the lifting plate 200 move relatively, the second wheel set 210 can still be driven to rotate. A driving motor 170 is fixedly arranged on the frame body 100, and a reducer 180 is arranged at the rotating shaft of the driving motor 170. The reducer 180 is connected to the first transmission belt 181 and the second transmission belt 182. The two ends of the first transmission belt 181 are respectively connected to the first driving member 150 and the reducer 180, and the two ends of the second transmission belt 182 are respectively connected to the first driving member 150 and the reducer 180. They are respectively connected to the second driving member 160 and the reducer 180; wherein the first driving member 150 and the second driving member 160 are both provided with pulleys, and the first transmission belt 181 and the second transmission belt 182 are respectively sleeved on the corresponding pulleys. During use, the driving motor 170 is started, and the rotation of the rotating shaft of the driving motor 170 is converted into driving the first transmission belt 181 to rotate and driving the second transmission belt 182 to rotate through the reducer 180. The first transmission belt 181 and the second transmission belt 182 respectively drive the first driving member 150 and the second driving member 160 to rotate, thereby driving the first wheel group 110 and the second wheel group 210 to rotate. In order to facilitate the first driving member 150 to drive the first wheel set 110 to rotate, a third transmission belt 183 is further arranged in the frame body 100, and the two ends of the third transmission belt 183 are respectively connected to the first driving member 150 and the first wheel set 110, which adopts a belt transmission method, specifically, the third transmission belt 183 is sleeved on the pulley on the first driving member 150 and the pulley on the rotating shaft of the first wheel set 110. During use, the driving motor 170 is started to drive the first transmission belt 181 to move, thereby driving the first driving member 150 to move, and the movement of the first driving member 150 drives the third transmission belt 183 to move, so as to drive the first wheel set 110 to move;

[0061] At the same time, the end of the second driving member 160 is connected to the telescopic universal coupling 161. The telescopic universal coupling 161 can drive the second wheel set 210 to rotate during the movement of the frame body 100 and the lifting plate 200, and can compensate for the axial displacement caused by temperature changes, mechanical loads or installation errors, thereby protecting the transmission system from damage. At the same time, because it can adapt to angular deviations, this coupling can reduce vibrations and impacts caused by shaft misalignment, improve the smooth operation of the system, and can adapt to a variety of different working environments.

[0062] Reference Figure 1-8 A fork assembly 300 is also fixedly arranged on the lifting plate 200, and the fork assembly 300 is convenient for picking up goods. When the frame body 100 contacts the ground, the lifting plate 200 continues to rise, and lifts the fork assembly 300 to a required height, so as to facilitate picking up goods at a specified height. At the same time, a plurality of reinforcing ribs 190 are arranged inside the frame body 100. Considering the stress condition of the vehicle body, right-angle reinforcing ribs and bridging-type reinforcing ribs are added to improve the strength of the vehicle body.

[0063] The implementation principle of a four-way shuttle vehicle in an embodiment of the present invention is as follows: the second driving member 160 acts on the second wheel set 210 through the telescopic universal coupling 161 to rotate it, and the first driving member 150 acts on the first wheel set 110 through the third transmission belt 183 to rotate it; the positive and negative screw drive, that is, the first control rod 120 drives the lifting plate 200 and the frame body 100 to move away from or approach each other, so that the first wheel set 110 contacts the ground and the second wheel set 219 contacts the ground, so that it can achieve reversing movement, wherein the threaded connection transmission mode enables it to accurately and stably maintain the height position, and during the reversing process, the lifting plate 200 moves, driving the fork assembly 300 to rise and fall, so that the goods are lifted and dropped; the four-way shuttle vehicle in the present invention changes the form of placing the control structure in the middle in the prior art, When the first control rod 120 is controlled to rotate in the middle, the first control rod 120 may bend and vibrate due to the long force arm; while controlling from the end can shorten the force arm, reduce such bending and vibration, and improve the stability and accuracy of movement; end control can usually provide better support and fixation, thereby enhancing the rigidity of the entire first control rod 120; in the present invention, the four-way shuttle uses fewer motors, and the reduction in the number of motors means that the potential failure points are reduced, thereby improving the reliability and stability of the shuttle, reducing the workload of daily maintenance and overhaul, and reducing maintenance costs and downtime. At the same time, reducing the number of motors can leave more space for cargo storage, improve the space utilization rate of the warehouse, and due to the reduction in the number of motors, the load of each motor is relatively reduced, which may extend the service life of the motor.

[0064] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
