DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1 to Figure 6 As shown, it is the first embodiment of the present invention, which provides a suspended conveying device for rice storage, including a lift adjustment structure 200, a tray structure 300 and a track structure 100. The top end of the lift adjustment structure 200 is inserted into the track structure 100 and forms a hanging connection with the track structure 100. The bottom end of the lift adjustment structure 200 is engaged in the tray structure 300 to drive the tray structure 300 to slide in the track structure 100.

[0035] The lift regulating structure 200 includes a lift regulating unit 210 and a hoisting unit 220 connected as one body. The lift regulating unit 210 reversely regulates its own rotation speed by sensing the gravity of the hoisting to obtain different lifts, and controls the displacement of the tray structure 300 by moving the hoisting unit 220.

[0036] Among them, the lift regulation unit 210 includes a fuselage frame, a flight control system and a handheld remote control 230 for starting and stopping the flight control system motor. The fuselage frame includes a fuselage body 211 and a rotor 212 installed on the fuselage body 211. Different lifts are generated by different rotation speeds of the rotor 212 to balance cargoes of different gravity. The flight control system includes a motor, an electronic speed regulator for controlling the motor speed and a gravity sensor 213 for sensing the gravity of the lift regulation unit 210. A control center is configured in the handheld remote control 230. The control center receives and analyzes the signal of the gravity sensor 213, controls the speed of the motor output end through the electronic speed regulator, and then adjusts the speed of the rotor 212.

[0037] Among them, the control center is equipped with a lift regulation mathematical model, which is:

[0038]

[0039] Wherein, X is the pulling force felt by the gravity sensor 213 when the pallet structure 300 is not loaded with goods; M is the mass of the stacked goods; ν is the rotation speed of the rotor 212; k is the lift coefficient; and g is the acceleration due to gravity.

[0040] Specifically, after a certain amount of bagged rice is loaded on the pallet structure 300, the pallet structure 300 is connected to the lift regulation unit 210 through the hoisting unit 220. When the lift regulation unit 210 rises to leave the ground, the lift regulation unit 210 transmits the monitored hoisting gravity to the control center, and the control center automatically calculates and changes the rotation speed of the rotor 212 so that the lift regulation unit 210 generates lower friction when running along the track structure 100.

[0041] Compared with the traditional lifting structure, the lifting structure bears a large weight and generates greater friction with the track structure 100. The lifting structure needs to be used with a lubricant during the lifting operation. Even when a lubricant is used, it will still frequently jam. In severe cases, the lifting structure will not be able to operate and will shut down. The present device is provided with a lift adjustment unit 210 between the track structure 100 and the lifting unit 220. The lift of the lift adjustment unit 210 is changed by changing the rotation speed of the rotor 212 to balance the tension and its own gravity, so as to reduce the force between the track structure 100 and the lift adjustment unit 210, reduce the amount of lubricating oil used, ensure the smooth operation of the suspended conveying device, and reduce the workload of subsequent maintenance.

[0042] The lift regulating structure 200 also includes a longitudinal driving structure 240, through which the longitudinal displacement of the pallet structure 300 is controlled. A transverse driving structure 110 is fixedly installed in the track structure 100, through which the transverse displacement of the pallet structure 300 is controlled. In the present invention, both the longitudinal driving structure 240 and the transverse driving structure 110 adopt multi-stage hydraulic cylinders, and the longitudinal and transverse displacements of the pallet structure 300 are directly or indirectly controlled by the movement of the piston rod of the multi-stage hydraulic cylinder. The specific models of the longitudinal driving structure 240 and the transverse driving structure 110 can be changed according to the actual use site, as long as the movement of the piston rod of the multi-stage hydraulic cylinder can be controlled while meeting the stroke requirements.

[0043] An electronic controller and a signal receiver for controlling the movement of the piston rod of the multi-stage hydraulic cylinder are installed in the multi-stage hydraulic cylinder. The joystick on the handheld remote control 230 is operated to send a radio signal. The signal receiver receives the radio signal and converts it into an electrical signal to transmit to the electronic controller. The electronic controller decides how to control the action of the multi-stage hydraulic cylinder according to the received signal to control the movement of the piston rod of the multi-stage hydraulic cylinder.

[0044] like Figure 4-Figure 5 As shown, a group of spindle sleeves 214 extend upward from the center of the fuselage body 211, and a special-shaped cavity 215 is provided inside the spindle sleeve 214, and an integrally connected elastic sheet 216 and a stretching rod 217 are sequentially assembled inside the special-shaped cavity 215, and the gravity sensor 213 is located between the elastic sheet 216 and the spindle sleeve 214, and the elastic sheet 216 and the spindle sleeve 214 are fixedly connected through the gravity sensor 213.

[0045] Specifically, when the lift regulating structure 200 is in the air, the gravity sensor 213 is subjected to a downward pulling force, and the pulling force comes from the cargo, the pallet structure 300 and the lift regulating structure 200, so that the gravity sensor 213 feels a certain pressure and sends a wireless signal to the control center. The control center receives and analyzes the signal of the gravity sensor 213, controls the speed of the motor output end through the electronic speed regulator, and then adjusts the rotation speed of the rotor 212 to obtain the corresponding lift to reduce the force between the lift regulating structure 200 and the track structure 100.

[0046] like Figure 2 , Figure 3 As shown, a clamp 218 is fixedly connected to the top end of the stretching rod 217 , and the clamp 218 includes an irregular plate 2181 and a positioning column 2182 .

[0047] The track structure 100 includes two groups of track units 120 and an extending cross plate 130 for connecting the track units 120. There are two groups of lift adjustment structures 200. The two groups of lift adjustment structures 200 are hoisted in the two groups of track units 120. The two groups of lift adjustment structures 200 are fixedly connected by a center plate. In the above-mentioned lift adjustment mathematical model, the rotation speed of the rotor 212 calculated by the lift adjustment mathematical model makes the lift generated by the rotation of the rotor 212 equal to half of the value of the pulling force felt by the gravity sensor 213 when stacking goods.

[0048] The track unit 120 includes a frame-shaped plate 121 and a clamping plate 122 integrally connected to the frame-shaped plate 121. The clamping plate 122 is welded to the inner wall of the frame-shaped plate 121 to make the inner cavity of the frame-shaped plate 121 uneven. An L-shaped push plate 123 is provided inside the frame-shaped plate 121 to match the inner cavity of the frame-shaped plate 121. The clamping head 218 passes through the L-shaped push plate 123 so that the positioning column 2182 is inserted into the L-shaped push plate 123 for positioning.

[0049] There are two groups of transverse driving structures 110 , which are respectively located on the surfaces of two groups of clamping plates 122 , and jointly drive the L-shaped push plate 123 to move linearly in the inner cavity of the frame plate 121 .

[0050] Working principle: The present invention provides a suspended conveying device for rice storage, which is mainly composed of a lift adjustment structure 200, a tray structure 300 and a track structure 100. The suspended conveying device for rice storage is used to solve the problems of low efficiency and high maintenance cost caused by friction during the operation of traditional lifting equipment. Specifically, by integrating the lifting unit 220 and the lift adjustment unit 210, and using the lift generated by the rotor 212 to offset the weight of the cargo, the direct contact between the lifting structure and the track is reduced, the wear and friction are reduced, and the efficient operation of the conveying device is ensured.

[0051] Specifically, the bagged rice is first placed on the pallet structure 300 for stacking. In addition, the pallet structure 300 is connected to the lift regulating unit 210 through the hoisting unit 220 to form a whole. The lift regulating unit 210 includes a body frame, a flight control system, and a handheld remote control 230. A plurality of rotors 212 are installed on the body frame, and the rotation speed of the rotors 212 is controlled by an electronic speed regulator in the flight control system. The electronic speed regulator adjusts the output speed of the motor according to the data from the gravity sensor 213, and then changes the rotation speed of the rotors 212 to generate appropriate lift to balance the weight of the cargo.

[0052] After the palletizing is completed, the operator sends a start command through the handheld remote control 230. After the signal receiver receives this command, the longitudinal drive structure 240 contracts, and the gravity sensor 213 is subjected to the tension and converts the tension into an electrical signal and transmits it to the control center. The control center then activates the lift adjustment unit 210, and the multiple rotors 212 on the body frame begin to rotate. The rotors 212 begin to rotate and generate lift. As the tension felt by the gravity sensor 213 increases, the control center controls the speed of the motor output end through the electronic speed regulator to increase, the speed of the rotor 212 increases, and the lift gradually increases until it is sufficient to overcome the total weight of the cargo, the pallet structure 300, the lift adjustment unit 210, and the hoisting unit 220.

[0053] Subsequently, the operator continues to send a start command through the handheld remote controller 230 , and the longitudinal drive structure 240 contracts, thereby causing the tray structure 300 to rise to a suitable position, and the handheld remote controller 230 remotely drives the tray structure 300 to move the lateral position to a specified position.

[0054] In the process from the lift regulating unit 210 starting to rise to the ground, the gravity sensor 213 continuously monitors the gravity borne by the hoisting unit 220 and transmits the data to the control center in real time. The control center calculates the required rotation speed of the rotor 212 based on the lift regulating mathematical model to maintain the dynamic balance between lift and gravity. This dynamic regulation mechanism ensures the stability and safety of the equipment throughout the entire operation cycle.

[0055] When rice needs to be transported from one location to another, the operator sends a command through the handheld remote controller 230. After receiving the command, the signal receiver converts it into an electrical signal and transmits it to the electronic controller. The electronic controller controls the piston rod of the multi-stage hydraulic cylinder according to the command, thereby realizing the movement of the pallet structure 300 in the track structure 100. At the same time, the lift adjustment unit 210 automatically adjusts the rotation speed of the rotor 212 according to the change of the load to maintain a constant lift level and ensure the stability of the goods during transportation.

[0056] Example 2

[0057] Reference Figure 1 , Figure 6 to Figure 8 As shown, it is the second embodiment of the present invention, which is based on the previous embodiment, except that the pallet structure 300 includes a pallet body 310, an upper roller plate 320 located on the upper surface of the pallet body 310, and a lower roller plate 330 located on the lower surface of the pallet body 310, a contraction groove 321 matched with the lower roller plate 330 is provided at the top end of the upper roller plate 320, and V-shaped grooves 322 are provided on two adjacent side surfaces of each group of upper roller plates 320.

[0058] There are four upper roller plates 320 and four lower roller plates 330 . The four upper roller plates 320 are located at the four corners of the upper surface of the tray body 310 , and the four lower roller plates 330 are located at the four corners of the lower surface of the tray body 310 .

[0059] A magnet 340 with opposite magnetic properties is embedded in the connection between the upper roller plate 320 and the lower roller plate 330. The purpose is to achieve the self-positioning function between the tray structure 300 and the tray structure 300 through the magnetic attraction characteristics of the magnet 340, without the need to add other structures to locate the position of the tray structure 300.

[0060] Secondly, the contraction groove 321 has a larger insertion port and a smaller abutment port, and the corresponding matching device has a smaller plug to expand the range of the tray structure 300 and the tray structure 300 when plugged in, so as to reduce the difficulty of self-positioning of the tray structure 300 and the tray structure 300.

[0061] Reference Figure 7 and Figure 8 As shown, the lifting unit 220 includes a rectangular frame plate 221, a chain assembly 222 and a protective assembly 223. The chain assembly 222 includes two groups, which are respectively located at the upper and lower ends of the protective assembly 223 and are integrally connected to the protective assembly 223. The rectangular frame plate 221 is fixedly connected to the protective assembly 223 through the chain assembly 222.

[0062] There are four groups of protection components 223. Each group of protection components 223 includes two protection plates 2231 inserted into the V-shaped groove 322 and a protection frame 2232 fixed between the two protection plates 2231. Multiple protection plates 2231 and multiple groups of protection frames 2232 form a rectangular frame.

[0063] Specifically, the protective frame 2232 includes a plurality of stainless steel rod balls 2233 and a connecting rod 2234. The connecting rod 2234 connects the plurality of stainless steel rod balls 2233 in series and is fixedly connected to two protective plates 2231 in a group of protective components 223. The stainless steel rod balls 2233 include a stainless steel center rod 22331 and a hollow ball 22332 located at the bottom end of the stainless steel center rod 22331. The stainless steel rod balls 2233 adopt a hollow structure to reduce the weight of the protective component 223 itself. At the same time, the stainless steel material has a certain strength and is not easy to rust, which gives a certain pressure to the bagged rice stacked on the pallet body 310 to ensure the stability of the bagged rice lifting operation process.

[0064] Specifically, the two groups of chain assemblies 222 are respectively an upper chain assembly 2221 and a lower chain assembly 2222. The upper chain assembly 2221 is rotatably installed on the top of the protective plate 2231, and the lower chain assembly 2222 is fixed to the bottom of the protective plate 2231. The upper chain assembly 2221 includes two chains 2223 extending downward from the corners of the rectangular frame plate 221. The two chains 2223 are respectively connected to two groups of connecting heads 2224 rotatably installed in the protective plate 2231. The rectangular frame plate 221 is connected to two adjacent protective plates 2231 through the upper chain assembly 2221. The lower chain assembly 2222 is opposite to the upper chain assembly 2221, and is additionally provided with a hinge for connecting the two chains 2223 to extend the lower chain assembly 2222.

[0065] Among them, the number of upper chain components 2221 is four groups, and the number of lower chain components 2222 is four groups.

[0066] Among them, the rectangular frame plate 221 is fixedly connected to the two groups of longitudinal drive structures 240, and two groups of reinforcing rods 241 are added at the connection between the rectangular frame plate 221 and the longitudinal drive structure 240 to increase the connection points of the longitudinal drive structure 240, so that the rectangular frame plate 221 can move horizontally during the lifting process.

[0067] Among them, the function of the lower chain assembly 2222 is to give the protective plate 2231 a downward force so that the protective plate 2231 can smoothly detach from the inside of the V-shaped groove 322 by relying on its own gravity. If the protective plate 2231 cannot smoothly detach from the inside of the V-shaped groove 322, the lower chain assembly 2222 can be pulled to give the protective plate 2231 a greater downward pressure, and the lower chain assembly 2222 can also be pulled to give the tray body 310 a guiding effect.

[0068] Working principle: The bagged rice is neatly stacked on the pallet body 310, and the protective plate 2231 is hooked into the V-shaped groove 322. The longitudinal driving structure 240 contracts to lift the rectangular frame plate 221, thereby straightening the chain 2223 of the upper chain assembly 2221. The straightened chain 2223 drives the protective plate 2231 to move upward, thereby driving the pallet body 310 to move upward, thereby causing the stacked bagged rice to be displaced.

[0069] Among them, the two chains 2223 in the upper chain assembly 2221 will be fixed to the top of the protective plate 2231 through the connecting head 2224, allowing the rectangular frame plate 221 to have a certain degree of rotation freedom during the lifting process to adapt to the pulling forces in different directions.

[0070] Among them, during the lifting process, the stainless steel rod ball 2233 in the protective frame 2232 will exert a certain pressure on the bagged rice to ensure that the goods will not loosen or shift during the lifting and transportation process.

[0071] The design of the V-shaped groove 322 helps to locate and fix the position of the bagged rice and reduce shaking during transportation.

[0072] Working principle: First, the rice bags are neatly stacked on the pallet body 310. Due to the design of the upper roller plate 320 and the lower roller plate 330, the pallet body 310 can be inserted into each other to improve the utilization rate of the longitudinal space for rice storage. The operator hooks the protective plate 2231 into the V-shaped groove 322, and the operator controls the handheld remote control 230 to hoist the pallet body 310 through the hoisting unit 220.

[0073] Specifically, the operator activates the lift adjustment unit 210 , the longitudinal drive structure 240 , and the transverse drive structure 110 through the handheld remote controller 230 to transport the tray body 310 and the bagged rice to a designated location.

[0074] Specifically, after receiving the start command, the signal receiver converts it into an electrical signal and transmits it to the control center. The control center activates the lift adjustment unit 210. As the lift adjustment unit 210 is started, the rotor 212 begins to rotate and gradually accelerates, generating an upward lift. In the initial stage, the lift is not enough to completely offset the total weight of the cargo and the pallet structure 300, and the lift adjustment unit 210 begins to rise slowly. During this process, the gravity sensor 213 continuously monitors the gravity borne by the hoisting unit 220 and transmits the data to the control center in real time. The control center calculates the required rotation speed of the rotor 212 based on the lift regulation mathematical model to maintain a dynamic balance between lift and gravity. As the lift gradually increases, the lift adjustment unit 210 continues to rise until the lift is sufficient to overcome the total weight of the cargo and the pallet structure 300, at which time the pallet body 310 completely leaves the ground and enters a suspended state.

[0075] Once in the suspended state, the operator controls the handheld remote controller 230 to move the lift adjustment structure 200 along the track structure 100. A transverse driving structure 110 is fixedly installed in the track structure 100, through which the transverse displacement of the tray structure 300 is controlled. At the same time, the longitudinal driving structure 240 located in the lift adjustment structure 200 is responsible for controlling the longitudinal displacement of the tray structure 300, and the precise positioning of the tray structure 300 in the track structure 100 is achieved through the cooperation of the electronic controller and the signal receiver.

[0076] In actual operation, when rice needs to be transported from one location to another, the operator sends a command through the handheld remote controller 230. After receiving the command, the signal receiver converts it into an electrical signal and transmits it to the electronic controller. The electronic controller controls the piston rod of the multi-stage hydraulic cylinder according to the command, thereby realizing the movement of the pallet structure 300 in the track structure 100. At the same time, the lift adjustment unit 210 automatically adjusts the rotation speed of the rotor 212 according to the change of the load to maintain a constant lift level and ensure the stability of the goods during transportation.

[0077] In the process of transporting rice from one side of the warehouse to the other side, if the height or lateral position needs to be adjusted midway, the operator can control it accordingly through the handheld remote controller 230. At this time, the signal receiver receives the command to adjust the height or position and transmits it to the electronic controller. The electronic controller adjusts the action of the multi-stage hydraulic cylinder according to the command, and maintains the overall balance of the system by changing the rotation speed of the rotor 212, ensuring that the equipment will not be unbalanced or out of control due to sudden load changes during the adjustment process.

[0078] In addition, due to the limitation of the visual field at a high altitude and the difficulty in accurately positioning the hoisting structure during operation, the device is provided with a contraction slot 321 and a plug adapted to the contraction slot 321 to expand the range of the tray structure 300 and the tray structure 300 when plugged in;

[0079] A magnet 340 with opposite magnetic properties is embedded at the connection between the upper roller plate 320 and the lower roller plate 330. The purpose is to realize the self-positioning function between the tray structures 300 and the tray structures 300 through the magnetic attraction characteristics of the magnet 340; when the tray body 310 approaches the tray body 310 at the lower end, the attraction between the magnets 340 begins to play a role, helping the rapid alignment and connection between the tray structures 300. This design not only guides the docking between the tray bodies 310, reduces the difficulty of docking between the tray bodies 310, but also improves the docking accuracy, ensuring that the docking task of the trays can be accurately completed even when the field of vision is limited at a high altitude. The design of the magnet 340 enables the trays to automatically attract and align when approaching, and even in the case of poor visibility, the docking can be completed through magnetic guidance.

[0080] When the distance between the two pallet bodies 310 is reduced to a certain extent, the upper roller plate 320 on the upper surface of the pallet body 310 and the lower roller plate 330 on the lower surface begin to contact. At this time, the contraction groove 321 opened at the top of the upper roller plate 320 is adapted to the lower roller plate 330 on the lower end of the pallet body 310 to form a stable plug-in structure. The design of the contraction groove 321 allows the lower roller plate 330 to be inserted more easily, and even in the case where it is difficult for the operator to accurately determine the positioning visually, the connection between the pallets can be easily achieved. This not only reduces the workload of the operator, but also improves work efficiency.

[0081] Specifically, in the actual operation process, when a pallet body 310 filled with rice bags needs to be lifted above another pallet body 310 that has been placed, the operator controls the lift adjustment unit 210 through the handheld remote control 230 to lift the pallet body 310 to an appropriate height and move it above the target position with the assistance of the track structure 100. At this time, the upper roller plate 320 of the pallet body 310 is about to contact the lower roller plate 330 of the lower pallet body 310. Due to the magnetic attraction characteristics of the magnet 340, the pallet body 310 will automatically align during the approach process, thereby achieving automatic positioning.

[0082] When the upper roller plate 320 and the lower roller plate 330 are in contact, the attraction between the magnets 340 further ensures the close fit between the two pallet bodies 310. Subsequently, the pallet bodies 310 continue to descend, and the contraction grooves 321 of the upper roller plate 320 cooperate with the plugs of the lower roller plate 330 to form a stable connection. In this process, even if the operator cannot accurately judge the relative positions of the pallet bodies 310 by naked eyes, the design of the magnets 340 and the contraction grooves 321 can be used to achieve rapid and accurate docking between the pallets.

[0083] After the docking is completed, the lift adjustment unit 210 can gradually reduce the lift so that the upper pallet body 310 completely falls on the lower pallet body 310. At this time, the entire structure becomes more stable and suitable for the next operation, such as continuing to stack more pallets or moving to a designated location for unloading. During the unloading process, the lift adjustment unit 210 provides more upward pulling force without increasing the downward force on the track structure 100, avoiding the problems of jamming or difficulty in separation that may be encountered in traditional methods.
