Description

Technical Field

[0001] This invention relates to the field of cargo transfer technology, and more specifically, to an energy-recovery type rail-mounted cargo loading, unloading and transfer device. Background Technology

[0002] In the field of cargo transfer and loading / unloading in warehousing and logistics, in response to the industry's demand for energy conservation, emission reduction and green development, energy recovery and storage technology has become an important design direction for warehousing and transfer devices. The core is to convert the gravitational potential energy carried by the heavy objects themselves into electrical energy of the generator through mechanical transmission during the loading, unloading and lifting of heavy objects, and then store the electrical energy in the energy storage module to achieve energy reuse.

[0003] When gravitational potential energy is converted into electrical energy, the quality of power generation directly determines the energy recovery efficiency and the safety of energy storage module. The stability of power generation quality depends on the rotation state of the generator drive wheel. It is necessary to ensure that the drive wheel maintains a near-uniform and stable rotation state in order to keep the voltage and current output by the generator constant.

[0004] In existing warehousing and cargo transfer scenarios, the goods are characterized by large loads and high gravitational potential energy. The transported goods are mostly palletized, boxed, and heavy, with a large single shipment. Given a fixed lifting height during loading and unloading operations, the high gravitational potential energy contained within these heavy objects is rapidly converted into the rotational kinetic energy of the generator drive wheel. This causes a sudden increase in generator rotor speed and imbalance, ultimately leading to drastic fluctuations in output voltage and current. This not only reduces the efficiency of converting gravitational potential energy into electrical energy but also subjectes the electrical components of the energy recovery module to frequent impacts, thus shortening the overall lifespan of the equipment.

[0005] In view of this, we propose an energy recovery type rail-mounted warehouse cargo loading and unloading transfer device to improve the above-mentioned shortcomings. Summary of the Invention

[0006] This invention provides an energy-recovery track-type warehouse cargo loading, unloading and transfer device, which solves the problem that when the gravitational potential energy contained in the cargo is large, the power generation quality is easily unstable due to the sudden increase in generator speed.

[0007] To achieve the above objectives, the energy recovery type rail-type storage cargo loading and unloading transfer device includes an I-shaped rail laid on the top of the base, a railcar rolling against the top of the I-shaped rail, and a mounting base fixedly connected to the top of the railcar. The top of the mounting base is provided with a support plate at an adjustable distance from itself. The two sides of the railcar are fixedly connected to generators that move synchronously with itself. Multiple springs are provided between the support plate and the mounting base. A conversion assembly is provided on one side of the support plate. The conversion assembly includes an active component and a passive component. The active component is fixedly connected to the support plate, and the passive component is coaxially connected to the drive wheel of the generator. When the support plate is far from the mounting base and at a high position, the support plate is used to support the heavy object and store gravitational potential energy. When the support plate moves closer to the mounting base from a high position, the driving member drives the driven member to rotate, so as to convert the gravitational potential energy of the heavy object into electrical energy of the generator. During the descent of the support plate, the spring slows down the descent speed of the heavy object and the support plate. During the descent and reset of the support plate, the spring is used to drive the generator to maintain the power generation state.

[0008] With this design, the gravitational potential energy of the heavy object is converted into electrical energy by the active component driving the driven component to rotate, thereby driving the generator to generate electricity and storing the gravitational potential energy of the heavy object as electrical energy. The close proximity of the support plate and the mounting base compresses the spring between them, and part of the gravitational potential energy of the weight is converted into the elastic potential energy of the spring and stored. After the weight on top of the support plate is unloaded, the support plate is reset under the action of the spring's restoring force. The support plate drives the driven component to rotate in the opposite direction through the active component, ensuring the continuity of generator power generation.

[0009] In another technical solution, an extension base is fixedly connected to one side of the railcar, and a sliding foot is fixedly connected to the bottom of the extension base. The sliding foot is slidably connected to the base and is used to support the generator to move synchronously with the railcar.

[0010] This technical solution, which designs the generator to move with the railcar, allows energy to be converted directly on the railcar. Compared to fixing the generator to the end of the I-beam rail, this design offers advantages such as a shorter path and less energy loss. Furthermore, energy can be recovered instantly whenever the load descends, without being limited by location.

[0011] In addition, the edge of the support plate is fixedly connected with multiple limiting feet. The limiting feet are located on the periphery of the support plate to ensure the bearing space at the top of the support plate. The top of the mounting base is fixedly connected with a sleeve rod at the corresponding position of each limiting foot.

[0012] Furthermore, the limiting foot is slidably connected to the corresponding sleeve rod below it, and the spring is sleeved around the sleeve rod to slow down the descent speed of the bearing plate and drive the bearing plate to reset.

[0013] The sleeve includes a first connecting rod and a second connecting rod. The bottom of the first connecting rod is fixedly connected to a fixing plate for fixing to the mounting base, and the top of the second connecting rod is fixedly connected to a limiting plate to prevent the bearing plate from slipping off.

[0014] Furthermore, the first connecting rod is fixedly connected to a transverse fixing bolt at the end away from the fixed plate, and the second connecting rod is fixedly connected to a transverse fixing groove at the end away from the limiting plate.

[0015] Furthermore, the transverse fixing bolt and the transverse fixing groove are slidably connected in the horizontal direction, and the transverse fixing bolt and the transverse fixing groove remain fixed in the vertical direction.

[0016] When the axes of the first link and the second link coincide, a fixing case is engaged around the transverse fixing bolt and the transverse fixing groove. The outer diameter of the fixing case is equal to the outer diameter of the first link and the second link, which is used to ensure that the first link and the second link can slide freely up and down inside the spring.

[0017] As can be seen from the above scheme, during the actual transfer of heavy objects by the railcar, the springs can be selected according to the different tonnages of the stored objects and the frequency of operation.

[0018] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: 1. The support plate supports the heavy object at a high position and stores gravitational potential energy. The heavy object drives the support plate to slide down along the surface of the first and second connecting rods. The spring is compressed synchronously, converting part of the gravitational potential energy into elastic potential energy, buffering and stabilizing the descent speed of the support plate, and preventing the generator drive wheel speed from rising suddenly. When the support plate descends, it drives the drive rack to slide downward, meshing with the drive gear to rotate, which in turn drives the generator drive wheel to rotate and generate electricity, converting gravitational potential energy into electrical energy and storing it.

[0019] 2. After the heavy load is unloaded, the spring releases its elastic potential energy to push the load-bearing plate back to its original position. Simultaneously, this drives the drive rack to slide upwards, and the drive gear rotates in the opposite direction. The generator can still maintain its power generation state, achieving energy recovery throughout the entire "lowering-resetting" cycle. In addition, the generator moves synchronously with the railcar, resulting in a short energy conversion path, low loss, and no restrictions on the working position, thus improving the flexibility and efficiency of energy recovery.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In existing technologies, warehouse cargo transfer scenarios involving energy recovery typically involve large cargo loads and high gravitational potential energy. The transported goods are often palletized, boxed heavy items with substantial single-cargo weight. Given a fixed lifting height during loading and unloading operations, the high gravitational potential energy contained within these heavy objects is rapidly converted into rotational kinetic energy for the generator drive wheel. This causes a sudden increase in generator rotor speed and imbalance, ultimately leading to drastic fluctuations in output voltage and current. This not only reduces the efficiency of converting gravitational potential energy into electrical energy but also subjectes the electrical components of the energy recovery module to frequent impacts, thus shortening the overall lifespan of the equipment.

[0024] Please see Figure 1 and Figure 2 In order to solve the problems existing in the prior art, the purpose of the present invention is to provide an energy recovery type rail-type warehouse cargo loading and unloading transfer device. The transfer device includes an I-shaped rail 110 laid on the top of the base 100, a railcar 120 rollingly attached to the top of the I-shaped rail 110, and an installation base 200 fixedly connected to the top of the railcar 120. The top of the mounting base 200 is provided with a support plate 210 with an adjustable spacing from itself. The two sides of the railcar 120 are fixedly connected to generators 320 that move synchronously with itself. Multiple springs 230 are provided between the support plate 210 and the mounting base 200. A conversion component is provided on one side of the support plate 210. The conversion component includes an active component and a passive component. The active component is fixedly connected to the support plate 210, and the passive component is coaxially connected to the drive wheel of the generator 320. When the support plate 210 is far away from the mounting base 200 and is at a high position, the support plate 210 is used to support the heavy object and store gravitational potential energy. When the support plate 210 moves closer to the mounting base 200 from a high position, the driving member drives the driven member to rotate, so as to convert the gravitational potential energy of the heavy object into electrical energy of the generator 320. During the descent of the support plate 210, the spring 230 slows down the descent speed of the heavy object and the support plate 210. During the ascent and reset of the support plate 210, the spring 230 is used to drive the generator 320 to maintain the power generation state.

[0025] During implementation, a heavy object is placed on top of the support plate 210. The heavy object presses the support plate 210, which is located at a high position, closer to the mounting base 200. The gravitational potential energy of the heavy object is converted into the rotation of the driven component through the active component, thereby driving the generator 320 to generate electricity and storing the gravitational potential energy of the heavy object as electrical energy. At the same time, the close proximity of the support plate 210 and the mounting base 200 compresses the spring 230 between them. A portion of the gravitational potential energy of the heavy object is converted into the elastic potential energy of the spring 230 and stored. After the heavy object on top of the support plate 210 is unloaded, the support plate 210 is reset under the action of the restoring force of the spring 230. During this period, the support plate 210 drives the driven component to rotate in the opposite direction through the active component, ensuring the continuity of power generation by the generator 320.

[0026] The formula for calculating gravitational potential energy is as follows: =m·g·h, where m is the mass of the object, g is the gravitational acceleration, and h is the relative height. Given a fixed mass, the height h of the receiving point directly determines the initial total gravitational potential energy of the object. The higher the starting point, the greater the vertical displacement difference between the object and the working plane of the railcar 120, resulting in more convertible gravitational potential energy. This provides more kinetic energy to drive the generator 320's drive wheels, ultimately increasing the total amount of electrical energy converted. This fundamentally solves the problem of low energy recovery efficiency during small-load, low-height operations in storage. Furthermore, a higher initial height allows for a stable gravitational potential energy difference during the lowering process, preventing insufficient potential energy and slow generator 320 speeds due to low heights. This ensures the generator 320 always operates within its efficient power generation range, reducing ineffective energy conversion losses.

[0027] Based on the above, an extension base 201 is fixedly connected to one side of the railcar 120, and a sliding foot 202 is fixedly connected to the bottom of the extension base 201. The sliding foot 202 is slidably connected to the base 100 and is used to support the generator 320 to move synchronously with the railcar 120.

[0028] The design described above, which arranges the generator 320 to move with the railcar 120, allows energy to be converted directly on the railcar 120. Compared to fixing the generator 320 to the end of the I-beam rail 110, this design has the advantages of a shorter path and less energy loss. Furthermore, energy can be recovered instantly whenever the load descends, without being limited by location.

[0029] For a better understanding of the above content, please refer to [link / reference]. Figure 3 and Figure 4 Multiple limiting feet 211 are fixedly connected to the edge of the bearing plate 210. The limiting feet 211 are located on the periphery of the bearing plate 210 to ensure the bearing space at the top of the bearing plate 210. A sleeve rod 220 is fixedly connected to the top of the mounting base 200 at the corresponding position of each limiting foot 211.

[0030] Furthermore, the limiting foot 211 is slidably connected to the corresponding sleeve rod 220 below it, and the spring 230 is sleeved around the sleeve rod 220 to delay the descent speed of the bearing plate 210 and drive the bearing plate 210 to reset.

[0031] exist Figure 5 and Figure 6 In the middle, the sleeve 220 includes a first connecting rod 221 and a second connecting rod 222. The bottom of the first connecting rod 221 is fixedly connected to a fixing plate 223 for fixing to the mounting base 200, and the top of the second connecting rod 222 is fixedly connected to a limiting plate 224 to prevent the bearing plate 210 from slipping off.

[0032] Furthermore, the first link 221 is fixedly connected to a transverse fixing bolt 225 at the end away from the fixed plate 223, and the second link 222 is fixedly connected to a transverse fixing groove 226 at the end away from the limiting plate 224.

[0033] Furthermore, the transverse fixing bolt 225 and the transverse fixing groove 226 are slidably connected in the horizontal direction, and the transverse fixing bolt 225 and the transverse fixing groove 226 remain fixed in the vertical direction.

[0034] When the axes of the first link 221 and the second link 222 coincide, the outer periphery of the transverse fixing bolt 225 and the transverse fixing groove 226 is engaged with a fixing housing 227. The outer diameter of the fixing housing 227 is equal to the outer diameter of the first link 221 and the second link 222, which is used to ensure that the first link 221 and the second link 222 can slide freely up and down inside the spring 230.

[0035] It should be noted that during the actual transfer of heavy objects by the railcar 120, the spring 230 can be selected according to the different tonnage of the stored objects and the frequency of operation. For example, by replacing the spring 230 with a different stiffness coefficient, there is no need to modify the structure of the bearing plate 210, generator 320, etc., which greatly improves the adaptability of the transfer device. For example, when operating light-loaded goods, the spring 230 with a smaller stiffness coefficient is selected to ensure smooth descent and power generation efficiency; when operating heavy-loaded goods, the spring 230 with a larger stiffness coefficient is selected to avoid excessive compression that could cause structural interference, so that the transfer device can be adapted to the transfer of goods of multiple weight levels in the warehouse.

[0036] Based on the above explanation, the following will further combine... Figure 7 Detailed explanation of the principles of the active and passive components of the conversion module: The driving component includes a drive rack 300, with a connecting frame 301 fixedly connected to the top of the drive rack 300. One end of the connecting frame 301 away from the drive rack 300 is fixedly connected to the support plate 210. The driven component includes a drive gear 310 rotatably connected to the extension base 201, and the drive gear 310 meshes with the teeth of the drive rack 300.

[0037] The generator 320 includes at least a body and a drive wheel. The body is fixedly connected to the top of the extension base 201 to move synchronously with the railcar 120. The drive gear 310 is coaxially connected to the drive wheel.

[0038] The generator 320 uses a permanent magnet synchronous motor, and its drive wheel can generate electricity by rotating forward and backward under the drive of the drive gear 310.

[0039] After the heavy object is placed on top of the support plate 210, since the support plate 210 is located at a high position in the storage, the heavy object itself has considerable gravitational potential energy, the magnitude of which is positively correlated with the mass of the heavy object and the initial height of the support plate 210. Under the action of gravity, the gravitational potential energy of the heavy object is converted into a downward driving force, which drives the support plate 210 to slide down along the surface where the first link 221 and the second link 222 overlap. During this process, the spring 230 between the support plate 210 and the top of the railcar 120 is gradually compressed as the support plate 210 descends. Part of the kinetic energy of the support plate 210 is converted into the elastic potential energy of the spring 230 and stored. At the same time, the elastic resistance of the spring 230 can offset part of the downward impact force, so that the downward movement of the support plate 210 remains stable and avoids instability in subsequent transmission and power generation due to a sudden increase in speed.

[0040] As the bearing plate 210 descends smoothly along the overlapping surfaces of the first connecting rod 221 and the second connecting rod 222, it simultaneously drives the fixed drive rack 300 to slide downwards in a straight line. Since the drive rack 300 and the drive gear 310 are meshed, the linear reciprocating motion of the drive rack 300 is directly converted into the rotational motion of the drive gear 310. That is, the downward sliding of the drive rack 300 causes the drive gear 310 to rotate around its own axis. The drive gear 310 is connected to the drive wheel of the generator 320 through a transmission. The rotation of the drive gear 310 synchronously drives the drive wheel of the generator 320 to rotate, triggering the electromagnetic induction generator mechanism of the generator 320 to convert mechanical rotational kinetic energy into electrical energy, thus realizing the energy conversion of the weight's gravitational potential energy into mechanical kinetic energy into electrical energy.

[0041] When the bearing plate 210 slides down to the lowest position along the overlapping surface of the first link 221 and the second link 222, the compression of the spring 230 reaches its maximum value, and the stored elastic potential energy also reaches its peak. At this time, the gravitational potential energy of the heavy object has been basically converted, including power generation and energy storage by the spring 230. The unloading operation of the heavy object on the top of the bearing plate 210 is completed at this lowest working position. After unloading, the bearing plate 210 loses the downward gravitational driving force, providing the motion conditions for the subsequent reset of the spring 230.

[0042] After the weight on top of the support plate 210 is removed, the spring 230 loses the pressure constraint of the weight and begins to release the stored elastic potential energy. Under the action of the elastic restoring force of the spring 230, the support plate 210 obtains an upward reset driving force and slides upward along the overlapping surface of the first link 221 and the second link 222 until it returns to the initial high-position receiving position. Since the drive rack 300 and the support plate 210 are fixedly connected, their movement states are completely synchronized. Therefore, when the support plate 210 resets upward, it synchronously drives the drive rack 300 to slide upward in a straight line. When the drive rack 300 slides upward, it still maintains meshing with the drive gear 310, driving the drive gear 310 to rotate in the opposite direction around its own axis. The reverse rotation of the drive gear 310 can still drive the drive wheel of the generator 320 to maintain rotation, thereby ensuring that the generator 320 continues to generate electricity during the reset phase of the support plate 210, realizing energy recovery of the device in the entire process of "weight lowering - spring 230 reset".

[0043] The following is combined Figure 8 The working principle of the transfer device is explained in detail: After a heavy object is placed on top of the support plate 210, the gravitational potential energy contained in the heavy object at a high position causes the support plate 210 to slide down along the overlapping surfaces of the first connecting rod 221 and the second connecting rod 222. During this process, the spring 230 is compressed and stores elastic potential energy. The descending support plate 210 drives the drive rack 300 to slide downwards, which in turn drives the drive gear 310 to rotate. The drive gear 310 then drives the drive wheel of the generator 320 to rotate and generate electricity. After the heavy object on top of the support plate 210 at its lowest position is unloaded, the support plate 210 returns to its original position under the restoring force of the spring 230. The drive rack 300, which rises synchronously with the support plate 210, then drives the drive gear 310 to rotate in the opposite direction to ensure that the generator 320 continues to generate electricity.

[0044] Spring 230 is involved in the entire process of the load-bearing plate 210 falling under the pressure of the heavy object and the load-bearing plate 210 resetting after unloading. Spring 230 can not only ensure that the load-bearing plate 210 falls smoothly, thereby ensuring the stable speed of the drive wheel of the generator 320, but also drive the load-bearing plate 210 to reset to the storage high position after unloading, and at the same time drive the drive gear 310 to rotate in the opposite direction to ensure the continuity of the generator 320's power generation process.
