[0031] It should be noted that the master control system can control the first control system, the second control system and the third control system respectively, so as to control the operation of the first transfer unit, the second transfer unit and the loading and unloading unit respectively.

[0032] There is an elevator entrance on each floor of the building. The live pigs enter the first transfer unit from the elevator entrance for transportation. The first transfer unit can move vertically to pass through or stay at the elevator entrance of each floor to transfer the live pigs on each floor to the first floor. The transportation method can be that the first transfer unit moves downward along the highest floor, stopping at each floor or the floor where it needs to stay to transport the live pigs.

[0033] During the transfer, the master control system controls the first control system to control the first transfer unit to load all the pigs that need to be transferred first, and then move to the first floor to transfer the loaded pigs to the second transfer unit; the master control system controls the second control system to control the second transfer unit to receive the pigs loaded by the first transfer unit, and after receiving, controls the second transfer unit to move to the loading and unloading unit, and the master control system controls the third control system to control the loading and unloading unit to unload the pigs loaded by the second transfer unit to the sales platform, thereby completing the transfer and sale of pigs from the pig house in the building to the sales platform. The entire transfer process does not require human intervention and is controlled by the master control system separately, which greatly improves the efficiency of pig transfer and sale, reduces the time of pig transfer and sale, and reduces labor costs.

[0034] On the basis of the above embodiments, as a further preference, the first transfer part includes a vertically arranged slide rail 1, a transfer mechanism is slidably provided on the slide rail 1, the transfer mechanism is slidably connected to the slide rail 1 through the sliding part, a winch is provided on the transfer mechanism, and the winch is signal-connected to the first control system.

[0035] It should be noted that the slide rail 1 is arranged on one side of the elevator entrance along each floor, and the winch can drive the transfer mechanism to move vertically along the slide rail 1 through the control of the first control system, and the sliding part slides with the slide rail 1, and the sliding part is arranged on the transfer mechanism. The first transfer part arranged in this embodiment has a simple structure and low cost.

[0036] The sliding part can be set on the side of the transfer mechanism to be slidably connected to the slide rail 1 on the side of the transfer mechanism. Setting the sliding part on the transfer mechanism can simplify the structure of the transfer mechanism without processing the part that is slidably connected to the slide rail 1 on the transfer mechanism.

[0037] On the basis of the above embodiment, as a further preference, the sliding part includes a pulley that slides in matching with the slide rail 1, and the pulley is connected to the transfer mechanism through a bracket.

[0038] It should be noted that the bracket can be welded to the side of the transfer mechanism or connected to the side of the transfer mechanism by bolts. The number of pulleys can be set to four, with two on the same side. The two pulleys on the same side are slidably connected to the same slide rail 1 to ensure that the transfer mechanism can move vertically smoothly along the slide rail 1.

[0039] On the basis of the above embodiment, as a further preference, an annular groove is provided on the circumference of the pulley, and a linear guide line matching and slidably connected with the annular groove is provided on the slide rail 1.

[0040] It should be noted that the shape of the linear guide line matches that of the annular groove, and the linear guide line extends into the annular groove. The pulley can be clamped on both sides of the linear guide line by the side walls of the annular groove so that the pulley will not easily detach from the slide rail 1, further ensuring the smooth operation of the transfer mechanism.

[0041] On the basis of the above embodiment, as a further preference, the transfer mechanism includes a base 5, a box body 2 is provided on the base 5, an openable and closable entrance door 3 is provided on one side of the box body 2, and an openable and closable exit door 7 is provided on the other side.

[0042] It should be noted that the base 5 is a flat structure for supporting the box body 2. The box body 2 is in the shape of a rectangular parallelepiped or a cube and is placed flat on the base 5. The entrance door 3 and the exit door 7 can be respectively arranged on the two opposite sides of the box body 2, or can be arranged on two non-opposite sides according to actual setting requirements. When the box body 2 stays at the elevator entrance of each floor, the exit door 7 is closed and the entrance door 3 is opened to allow the live pigs to enter the box body 2. When all the live pigs are loaded and stay on one floor, the entrance door 3 is closed and the exit door 7 is opened to transport the live pigs to the second transport section.

[0043] On the basis of the above embodiment, as a further preference, the box body 2 is provided with a door 7 on one side of the bottom end which is hinged to the base 5, and a lifting device 4 is provided between the side surface of the box body 2 and the base 5, one end of the lifting device 4 is hinged to the box body 2, and the other end is hinged to the base 5, the lifting device 4 is used to drive the box body 2 to flip along the hinge point where the box body 2 is hinged to the base 5, and the lifting device 4 is connected to the first control system signal.

[0044] It should be noted that the lifting device 4 in this embodiment can be a gas cylinder, an oil cylinder or other device. When the live pigs are transported to the second transfer section, the lifting device 4 rises, driving the box body 2 to flip around the hinge point where the box body 2 is hinged to the base 5, and at the same time opens the door 7, and uses gravity to make the live pigs slide out of the box body 2 along the door 7 and enter the second transfer section. There is no need for manual driving operation, which is efficient, fully automated and controlled, and reduces labor costs.

[0045] On the basis of the above embodiment, as a further preference, the upper edge of the door 7 is hinged to the box body 2, and a telescopic device 6 is provided between the door 7 and the box body 2, one end of the telescopic device 6 is hinged to the box body 2, and the other end is hinged to the door 7, and the telescopic device 6 is connected to the first control system signal.

[0046] It should be noted that when the lifting device 4 drives the box body 2 to tilt and flip, the first control system controls the telescopic device 6 to extend to open the door 7, so that the pigs can slide out of the box body 2. When all the pigs enter the second transfer part, the first control system controls the telescopic device 6 to retract and close the door 7 to prepare for the next transfer. The telescopic device 6 in this embodiment can be a telescopic device 6 such as a cylinder or an oil cylinder. The telescopic device 6 can open and close the door 7 without manual intervention, and is automatically controlled to reduce labor costs.

[0047] On the basis of the above embodiment, as a further preference, a first guide plate 8 is provided on the bottom edge of one side of the box body 2 where the door 7 is provided. The first guide plate 8 is tilted upward and forms a first preset angle with the bottom plate of the box body 2 .

[0048] It should be noted that the upward tilt of the first guide plate 8 can make the first guide plate 8 face the second transfer part when the box body 2 is tilted and flipped, so that the height of the second transfer part can be flexibly set, and the live pigs can be supported when sliding out of the box body 2 until they move to the second transfer part to prevent the live pigs from falling during transportation.

[0049] On the basis of the above embodiment, as a further preference, the second transfer unit is a transfer vehicle 10, and the transfer vehicle 10 includes a vehicle body 11 and a door arranged on one side of the vehicle body 11, and the door is driven to open and close by a first drive device, and the first drive device is connected to the second control system signal.

[0050] It should be noted that the first driving device can be an electric push rod or a cylinder, one end of the electric push rod or the cylinder is hinged to the vehicle body 11, and the other end is hinged to the vehicle door. When the vehicle door needs to be opened, the first driving device drives the vehicle door to open so that the pigs can enter the vehicle body 11. When the vehicle door needs to be closed, the first driving device drives the vehicle door to close so that the pigs cannot walk out of the vehicle door. The second transport part provided in this embodiment has a simple structure, and the vehicle door can be automatically opened and closed by the second control system.

[0051] On the basis of the above embodiment, as a further preference, an opening and closing door is provided at the rear end of the vehicle body 11, and the opening and closing door is driven to switch by a second drive device. The opening and closing door is used to open when the loading part unloads the pigs on the transfer vehicle 10. The second drive device is connected to the second control system signal, and the second drive device can be an electric push rod or a cylinder.

[0052] On the basis of the above embodiment, as a further preference, the vehicle door includes an upper door 13 whose upper part is hinged to the vehicle body 11 and a lower door 12 whose upper part is hinged to the upper door 13, one end of the first drive device is hinged to the upper door 13, and the other end is hinged to the vehicle body 11.

[0053] It should be noted that the upper door 13 is hinged to the vehicle body 11, and the upper end of the lower door 12 is hinged to the lower end of the upper door 13 through a hinge, and the hinge is set as a hinge. When the upper door 13 and the lower door 12 are opened, the upper door 13 flips around the hinge point where it is hinged to the vehicle body 11. During this process, the lower door 12 is always in a vertical state, and the upper door 13 rotates around the hinge relative to the lower door 12. The inner side of the lower end of the upper door 13 and the inner side of the upper end of the lower door 12 are respectively connected to the hinge, which prevents the lower door 12 from flipping to the outside of the vehicle body 11 when the upper door 13 and the lower door 12 are both closed, thereby improving safety.

[0054] On the basis of the above embodiment, as a further preference, the vehicle body 11 is provided with an upper door 13 and a lower door 12 and a second guide plate 9 is upwardly tilted at the bottom of one side, and the second guide plate 9 forms a second preset angle with the bottom plate of the vehicle body 11 .

[0055] It should be noted that the second guide plate 9 is tilted upward, and when the box body 2 is turned toward the vehicle body 11, the first guide plate 8 and the second guide plate 9 can be placed on the same straight line, forming a passage between the box body 2 and the vehicle body 11 to further prevent the pigs from falling during transfer. Moreover, based on this embodiment, the upper door 13 can be turned toward the outside of the vehicle body 11 when it is opened, and when the upper door 13 and the lower door 12 are closed, the upper door 13 is driven downward by the first driving device to drive the lower door 12 downward, so that the pigs staying on the second guide plate 9 can be driven into the vehicle body 11.

[0056] On the basis of the above embodiments, as a further preference, the transfer vehicle 10 includes a frame, a pair of steering wheels 24 arranged at the bottom of the front end of the frame, and a pair of driving wheels 36 arranged at the bottom of the rear end of the frame, the two steering wheels 24 are respectively connected to the front steering system, the two driving wheels 36 are both connected to the rear steering system and are both connected to the driving system, and an annular photoelectric switch is provided at the bottom of the frame for detecting whether the steering wheel 24 and / or the driving wheel 36 are returned to the center, and the annular photoelectric switch is connected to the second control system signal.

[0057] It should be noted that the structure of the frame can be selected according to the site settings. Since the passages within the factory are narrow, the frame cannot be set too wide so that it cannot turn freely. The drive system is used to drive the frame forward or backward, and the steering system is used to drive the frame to turn so that the frame can turn.

[0058] The driving wheel 36 drives the transfer vehicle 10 forward, and the driving system is used to drive the driving wheel 36 to rotate. There can be multiple driving systems, which can be flexibly set according to actual applications. The driving wheel 36 can steer like the steering wheel 24, and is driven to steer by the rear steering system, and the steering wheel 24 is driven to steer by the front steering system.

[0059] This embodiment can move forward, backward or stop under the drive of the drive system. The two steering wheels 24 are connected to the front steering system, and the driving wheel 36 is connected to the rear steering system so that both the two steering wheels 24 and the two driving wheels 36 have the ability to turn. When turning in a narrow passage, the front and rear steering can be used to turn the front and rear ends of the frame at the same time, thereby improving the performance of the transfer vehicle 10 in passing through narrow bends. In addition, an annular photoelectric switch is provided at the bottom of the frame to detect whether the driving wheel 36 and / or the steering wheel 24 are returned to the correct position, and the detection signal is sent to the second control system. The second control system can adjust the driving wheel 36 and / or the steering wheel 24 according to the signal sent by the annular photoelectric switch, thereby ensuring the accuracy of the movement of the transfer vehicle 10.

[0061] It should be noted that the front axle 25 is fixedly arranged at the front end of the bottom of the frame, and the first universal joints are respectively installed at both ends of the front axle 25, so that the two steering wheels 24 can operate under various working conditions. The first steering arm arranged on the first universal joint is connected to the first steering machine 28, and the first steering arm is connected to the fork arm of the first universal joint connected to the steering wheel 24. Under the drive of the first driving motor 29, the first steering machine 28 can drive the first steering arm to move, thereby pulling the first steering arm to deflect left and right, and driving the fork arm to deflect at the same time, so as to drive one steering wheel 24 to turn. The first trapezoidal arms 27 arranged on the two first universal joints are connected through the first transverse tie rod 26, and the two first trapezoidal arms 27 are arranged on the fork arm of the first universal joint connected to the steering wheel 24, so that the two steering wheels 24 can deflect synchronously. When one steering wheel 24 turns, it will drive the other steering wheel 24 to turn at the same time, thereby completing the steering of the front end of the frame. The front steering system provided in this embodiment has a simple structure and reliable steering.

[0062] On the basis of the above embodiments, as a further preference, the rear steering system includes a first rear axle 32, and second universal joints 35 are respectively provided at both ends of the first rear axle 32, a second steering arm 33 is provided on a second universal joint 35, the second steering arm 33 is connected to the second steering gear 31, and the second steering gear 31 is connected to the second driving motor 38; second trapezoidal arms 34 are respectively provided on the two second universal joints 35, the two second trapezoidal arms 34 are connected by a second transverse tie rod 37, the two second universal joints 35 are respectively connected to the bushings, the two driving wheels 36 are respectively provided with rotating shafts, the two rotating shafts are respectively arranged in two bushings, and the first rear axle 32 is arranged on the frame.

[0063] It should be noted that the first rear axle 32 is fixedly arranged at the rear end of the bottom of the frame, and second universal joints 35 are respectively installed at both ends of the first rear axle 32, so that the two bushings can achieve universal motion, thereby enabling the two rotating shafts to achieve universal motion, ensuring that the two driving wheels 36 can operate under various working conditions. The second steering arm 33 arranged on the second universal joint 35 is connected to the second steering machine 31, and the second steering arm 33 is connected to the fork arm of the second universal joint 35 connected to the bushing. Under the drive of the second driving motor 38, the second steering machine 31 can drive the second steering arm 33 to move, thereby pulling the second steering arm 33 to deflect left and right, and at the same time drive the fork arm to deflect, so as to drive one driving wheel 36 to turn. The second trapezoidal arms 34 arranged on the two second universal joints 35 are connected by a second transverse tie rod 37. The two second trapezoidal arms 34 are arranged on the fork arm of the second universal joint 35 connected to the bushing, so that the two driving wheels 36 can deflect synchronously. When one driving wheel 36 turns, it will drive the other driving wheel 36 to turn at the same time, thereby completing the steering of the rear end of the frame. The rear steering system provided by this embodiment has a simple structure and reliable steering.

[0064] On the basis of the above embodiment, as a further preference, the first rear axle 32 is a hollow shaft, the drive system includes a drive shaft arranged in the first rear axle 32, the two ends of the drive shaft are respectively connected to the two rotating shafts through the third universal joint, and the drive shaft is connected to the third drive motor 30. It should be noted that the drive shaft is connected to the third drive motor 30 through a transmission mechanism, the drive shaft is a power output shaft, and the two ends of the drive shaft are respectively connected to the rotating shaft through two third universal joints, which can ensure that the rotating shaft can move with the shaft sleeve for easy steering. The drive system set in this embodiment has a simple structure and reliable transmission, which is convenient for moving forward, backward and steering.

[0065] On the basis of the above embodiment, as a further preference, the drive system includes a second rear axle 32 and hub motors respectively arranged on two drive wheels 36, and the two drive wheels 36 are respectively connected to the second rear axle 32 through a fourth universal joint.

[0066] It should be noted that the wheel hub motor is used as an active part to drive the two drive wheels 36 to rotate, and the wheel hub motor is directly arranged on the two drive wheels 36 without other shaft transmission, so a large number of transmission components can be omitted, making the structure of the transport vehicle 10 simpler. The two drive wheels 36 are connected to the second rear axle 32 through the fourth universal joint, so that the two drive wheels 36 can adapt to more working conditions.

[0067] On the basis of the above embodiments, as a further preference, the rear steering system includes third trapezoidal arms respectively arranged on the fork arms of two fourth universal joints connected to the two driving wheels 36, the two third trapezoidal arms are connected by a third transverse tie rod, a third steering arm is provided on a fourth universal joint, the third steering arm is connected to the third steering gear, and the third steering gear is connected to the fourth driving motor.

[0068] It should be noted that, since the transmission structure of the drive system is saved, the third trapezoidal arm can be directly set on the fork arm of the fourth universal joint connected to the two drive wheels 36. The third steering gear is driven by the fourth drive motor to move, which can drive the third steering arm to move and drive one drive wheel 36 to steer. Since the two third trapezoidal arms are connected by the third transverse tie rod, the two drive wheels 36 can achieve synchronous steering.

[0069] On the basis of the above embodiments, as a further preference, the loading and unloading part includes: a support seat 18, a supporting mechanism for supporting the tail of the transfer vehicle 10, a lifting mechanism for lifting the bottom of the transfer vehicle 10, and a driving mechanism for driving the lifting mechanism to lift the transfer vehicle 10, the lifting mechanism is hinged to the supporting mechanism, the driving mechanism is hinged to the lifting mechanism, and the supporting mechanism is fixedly arranged on the support seat 18.

[0070] It should be noted that the structure of the support seat 18 can be any structure. The support seat 18 is placed on the ground. Since the support seat 18 serves as the basis of the support mechanism and is used to support the support mechanism, the support seat 18 needs to be placed stably on the ground. When the tail of the transfer vehicle 10 is attached to and applies force to the support mechanism, the support seat 18 cannot move or shake to increase the stability of the support seat 18.

[0071] The supporting mechanism is used to support the rear of the transfer vehicle 10. Since a fulcrum needs to be set when the transfer vehicle 10 is lifted, the supporting mechanism serves as the fulcrum of the transfer vehicle 10. When the lifting mechanism lifts the transfer vehicle 10, the transfer vehicle 10 will rotate in a vertical plane with the supporting mechanism as the fulcrum to achieve the effect of lifting and flipping.

[0072] The lifting mechanism is arranged at the bottom of the transfer vehicle 10, and the specific location can be set according to the actual application situation. When lifting, the bottom of the transfer vehicle 10 is lifted upward under the drive of the driving mechanism to lift the front of the transfer vehicle 10. When the front of the transfer vehicle 10 is lifted, the opening and closing door is opened, and all the live pigs slide out of the vehicle body 11 under the action of gravity.

[0073] The driving mechanism can be any mechanism as long as it can drive the lifting mechanism to lift the transfer vehicle 10. Commonly used driving mechanisms can be hydraulic telescopic mechanisms or pneumatic telescopic mechanisms. The specific selection can be made based on comprehensive considerations of actual application and cost.

[0074] This embodiment is arranged on the ground, based on the support seat 18, with the support mechanism as the fulcrum, and the lifting mechanism is driven by the driving mechanism to move. Since the lifting mechanism is hinged to the support mechanism, the movement of the lifting mechanism during lifting is to rotate in the vertical plane around the hinge point hinged to the support mechanism, thereby driving the transfer vehicle 10 to rotate in the vertical plane around the support mechanism at the rear, thereby achieving the purpose of flipping the transfer vehicle 10. Since this embodiment is not arranged on the transfer vehicle 10, it is a separate structure from the transfer vehicle 10, which simplifies the structure of the transfer vehicle 10, reduces the weight of the transfer vehicle 10, and thus reduces the cost.

[0075] On the basis of the above embodiment, as a further preference, the supporting mechanism includes a baffle 19 for supporting the rear end of the transfer vehicle 10 and a pallet 20 for supporting the bottom surface of the rear end of the transfer vehicle 10 , the baffle 19 is arranged on the support seat 18 , and the pallet 20 is arranged on the baffle 19 .

[0076] It should be noted that the baffle 19 supports and blocks the rear end of the transfer vehicle 10. When the transfer vehicle 10 is reversed into the lifting and flipping device of the transfer vehicle 10, the reversing is stopped when the rear end of the transfer vehicle 10 is in contact with the baffle 19, so as to facilitate the positioning of the transfer vehicle 10. The support plate 20 and the baffle 19 can usually be set at an angle to each other to adapt to a variety of rear structures of the transfer vehicles 10. The horizontal and vertical two-way limiting of the baffle 19 and the support plate 20 can stably support the rear end of the transfer vehicle 10, thereby improving the safety of the transfer vehicle 10 during the lifting process.

[0077] On the basis of the above embodiment, as a further preference, the lifting mechanism includes two cross arms 17 hinged on the support plate 20 and a lifting frame arranged between the cross arms 17, and a preset distance is set between the two cross arms 17.

[0078] It should be noted that the cross arm 17 can be set to a strip shape, the tail ends of the two cross arms 17 are respectively hinged to the support plate 20, and the front end is fixedly installed with a lifting frame, which is set at the bottom of the transfer vehicle 10 and can fit the ground in a natural state. The two ends of the lifting frame are respectively connected to the front ends of the two cross arms 17, and the preset distance between the two cross arms 17 can be flexibly set according to the width of the transfer vehicle 10 to be lifted. When the transfer vehicle 10 is poured into the lifting and flipping device, the two cross arms 17 are respectively on both sides of the transfer vehicle 10. The lifting mechanism provided in this embodiment has a simple structure, is easy to install and operate, and has a low cost.

[0079] On the basis of the above embodiment, as a further preference, the lifting frame includes two lifting vertical rods 14 and a lifting horizontal rod 15 arranged between the bottoms of the two lifting vertical rods 14, and the tops of the two lifting vertical rods 14 are respectively connected to the ends of two horizontal arms 17.

[0080] It should be noted that the lifting vertical rod 14 and the lifting cross rod 15 are arranged at an angle to each other, the upper ends of the two lifting vertical rods 14 are respectively fixedly connected to the front ends of the two cross arms 17, and the two ends of the two lifting cross rods 15 are respectively connected to the bottom ends of the two lifting vertical rods 14. When the transfer vehicle 10 is poured into the transfer vehicle 10 lifting and flipping device, the two lifting vertical rods 14 are respectively located on both sides of the transfer vehicle 10, and the lifting cross rod 15 is located at the bottom of the transfer vehicle 10. When lifting, the lifting vertical rod 14 drives the lifting cross rod 15 to move upward, and the lifting cross rod 15 lifts the transfer vehicle 10. The lifting frame provided in this embodiment has a simple structure and low cost.

[0081] On the basis of the above embodiment, as a further preference, the driving mechanism includes two hydraulic cylinders 16, the upper ends of the two hydraulic cylinders 16 are respectively hinged to the cross arms 17, and the lower ends are respectively hinged to the ground.

[0082] It should be noted that the hydraulic cylinder 16 has the advantages of light weight, small size, long life, small inertia, fast reaction speed, and convenient operation and control, and can achieve a wide range of stepless speed regulation and automatic overload protection. When lifting, the extension of the hydraulic cylinder 16 can drive the cross arm 17 to move upward, thereby driving the lifting cross bar 15 to lift the transfer vehicle 10 upward. The contraction of the hydraulic cylinder 16 can drive the cross arm 17 to move downward, thereby driving the lifting cross bar 15 to lower the transfer vehicle 10.

[0083] On the basis of the above embodiment, as a further preference, it also includes a detection mechanism for detecting whether the rear end of the transfer vehicle 10 contacts the support mechanism, and the detection mechanism is arranged on the support seat 18.

[0084] It should be noted that the detection mechanism is used to detect whether the rear end of the transfer vehicle 10 contacts the support mechanism. If not, the position of the transfer vehicle 10 is adjusted until the detection mechanism detects the support mechanism, and then the lifting mechanism can be started to lift the transfer vehicle 10, thereby completing the flipping of the transfer vehicle 10. Setting up the detection mechanism can detect whether the transfer vehicle 10 has reached the specified position, which is convenient and quick.

[0085] On the basis of the above embodiments, as a further preference, the detection mechanism includes a travel switch, a pressure sensor or a photoelectric sensor.

It is suitable for this application. The pressure sensor has the advantages of small size, easy disassembly and assembly, and high sensitivity. When the tail of the transfer vehicle 10 generates pressure on the pressure sensor, a signal is immediately generated, and it can be known that the transfer vehicle 10 has reached the designated position.

[0087] On the basis of the above embodiment, as a further preference, a position mechanism for detecting the rotation angle of the lifting mechanism is also included.

[0088] It should be noted that by setting up a positioning mechanism, the rotation angle of the lifting mechanism can be detected. When the lifting mechanism rotates to a preset angle, the positioning mechanism can send a signal after detecting it. After the staff learns of it, they can control the lifting mechanism to stop rotating to prevent over-turning and rollover.

[0089] On the basis of the above embodiments, as a further preference, the positioning mechanism includes a fan-shaped plate 23 arranged on the support seat 18, and the fan-shaped plate 23 is provided with at least one position sensor 21 protruding from the arc-shaped outer periphery of the fan-shaped plate 23, and the lifting mechanism is provided with a touch rod 22. When the lifting mechanism rotates to a preset angle, the touch rod 22 contacts the position sensor 21.

[0090] It should be noted that an arc-shaped strip hole can be set on the fan-shaped plate 23, and all position sensors 21 are set in the strip hole. All position sensors 21 can move along the strip hole and can be fixed at any position of the strip hole. The center of the strip hole is the same as the center of the fan-shaped plate 23.

[0091] The angle of the central angle of the fan plate 23 can be set according to the actual application. In this embodiment, the angle of the central angle of the fan plate 23 can be set to degrees. One of the right-angled sides of the fan plate 23 is set horizontally, and the other right-angled side is set vertically. The plate surface of the fan plate 23 is parallel to the rotation plane of the lifting mechanism. The rotation angle of the touch rod 22 can be checked through the position of the touch rod 22, so as to know the rotation angle of the lifting mechanism. When the touch rod 22 contacts the position sensor 21, a signal can be sent, and the staff can know the rotation angle of the lifting mechanism, thereby controlling the rotation angle of the lifting mechanism. This embodiment has a simple structure and obvious signal transmission, and the staff can get an obvious signal.

[0092] On the basis of the above embodiments, as a further preference, a navigation system for guiding the movement direction of the frame is provided on the frame, and the second control system is used to receive signals from the navigation system to control the operation of the drive system, the front steering system and the rear steering system to control the movement direction of the frame.

[0093] It should be noted that the navigation system is used to locate the position of the transfer vehicle 10 and the direction of movement of the guide frame. The second control system receives the signal from the navigation system to know the specific position of the frame and the direction in which the frame is about to move. After receiving the turning signal from the navigation system, the second control system will control the operation of the steering system, thereby controlling the turning of the frame.

[0094] On the basis of the above embodiments, as a further preference, the navigation system includes a reader and an electromagnetic sensor, the reader is used to read the RFID chip set on the ground to locate the position of the frame, the electromagnetic sensor is used to sense the electromagnetic wire pre-buried in the ground from the first transfer part to the loading and unloading part, the second control system receives the signal of the electromagnetic sensor to control the operation of the drive system, the front steering system and the rear steering system, the reader is connected to the second control system signal, and the reader and the electromagnetic sensor are both set at the bottom of the frame.

[0095] It should be noted that the RFID chip is laid on the ground along the passage from the first transfer part to the loading and unloading part, and the electromagnetic wire is pre-buried in the passage ground of the factory area. The electromagnetic sensor can sense the electromagnetic signal of the electromagnetic wire, and the electromagnetic sensor transmits the signal to the second control system. The second control system can control the action of the drive system, the front steering system and the rear steering system according to this signal to control the forward direction of the frame. The position information read by the reader can be transmitted to the second control system, and the second control system can control the transfer vehicle 10 to move forward or stop according to the position information.

[0096] Based on the above embodiment, as a further preference, the front end and the rear end of the bottom of the frame are respectively provided with an electromagnetic sensor and a reader. The arrangement of this embodiment can make the electromagnetic sensors at the front end and the rear end of the frame sense electromagnetic signals, and the reader reads the front end position and the rear end position of the frame, so that the positioning information is more accurate, and the second control system controls the movement of the frame more accurately.
