Description

Technical Field

[0001] This utility model belongs to the field of gravity energy storage power generation technology, specifically relating to a heavy object conveying and transfer platform based on slope gravity energy storage. Background Technology

[0002] In gravity energy storage systems, the weight and operating speed of the load are key indicators affecting the system's performance. As a crucial component for bearing, transporting, and transferring heavy loads, the design of the load transport platform has a vital impact on the overall system performance. Currently, there are no dedicated transport platforms developed for slope-based gravity energy storage. Ordinary transport vehicles are mostly flatbed or box-type, used for transporting goods on horizontal or gently sloping surfaces at relatively low speeds, and are unsuitable for the operating conditions and technical requirements of slope-based gravity energy storage. In particular, the slopes in gravity energy storage systems require a significant gradient and are generally constructed based on existing terrain, resulting in variations in slope. Therefore, the loads carried on the transport vehicles will also be tilted when operating on slopes, with the tilt angle changing with the slope, posing a risk of displacement or tipping of the loads on the transport vehicles. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heavy object conveying and transfer platform based on slope gravity energy storage, which solves the problem that existing conveying vehicles cannot meet the requirements of slope gravity energy storage, and avoids heavy objects from sliding or tipping over due to the slope, thereby improving the operational stability and safety of the gravity energy storage system.

[0004] According to the technical solution of this utility model, this utility model provides a heavy object conveying and transfer platform based on slope gravity energy storage, including a main frame, with wheels installed at the bottom of the main frame; a top frame is installed above the main frame, one end of the top frame is rotatably connected to the main frame, and the other end of the top frame is connected to the main frame through an angle adjustment device to keep the top frame horizontal; a lifting and transfer device is installed above the top frame, and the upper surface of the lifting and transfer device is a heavy object bearing surface capable of vertical lifting, horizontal extension or horizontal transport.

[0005] In some embodiments, the lifting and transferring device includes a vertical lifting assembly and a horizontal telescopic assembly connected together, one of which is connected to a top frame, and the upper surface of the other of the vertical lifting assembly and the horizontal telescopic assembly is a load-bearing surface.

[0006] In some embodiments, the lifting and transfer device includes a vertical lifting assembly disposed above the top frame, and a conveying mechanism disposed above the vertical lifting assembly.

[0007] In some embodiments, a weight stabilizing device is also included, which includes two or more stabilizing blocks located above the load-bearing surface of the weight and distributed around the weight; the stabilizing blocks are connected to a movable mechanism to enable the weight to be gripped and released.

[0008] In some embodiments, when the weight is held, the weight is in the weight holding position; the side above the weight bearing surface where the weight moves in and out of the weight holding position as the lifting and conveying device extends or is transported horizontally is the weight entry / exit side; the movable mechanism connected to the stabilizing block located on the weight entry / exit side is the entry / exit clearance mechanism, which enables the stabilizing block to be raised, lowered, moved, or flipped to clear the space required for the weight to move in and out on the weight entry / exit side; the movable mechanism connected to the stabilizing blocks on the other sides above the weight bearing surface is the stabilizing block telescopic mechanism, which enables the stabilizing block to extend inward toward the weight holding position and retract outward toward the weight holding position.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] The load-bearing surface (top surface) of the gravity-based transport and transfer platform of this invention is set at an angle to the bottom surface of the main frame (i.e., the slope surface), and can be adjusted by an angle adjustment device to keep the load-bearing surface horizontal or at least prevent large tilt angles. Furthermore, in sections where the actual angle of the slope changes, the angle adjustment can be automatically controlled based on pre-programming or real-time detection. Therefore, this solution can ensure that the load does not tilt (significantly) during the transport or transfer process, effectively preventing the load from sliding downwards during operation, avoiding safety accidents, and improving the stability of the gravity energy storage system. In addition, this solution also has a lifting and transfer device responsible for loading, unloading, and transferring the load. The lifting and transfer device can effectively compensate for the height deviation between the platform and the external platform after the platform has stopped. The extension and retraction or conveying device can automatically send the load into and out of the platform, reducing the working time of other load transfer methods (such as crane grabbing) and improving the efficiency of the gravity energy storage system.

[0022] This invention provides a heavy object conveying and transfer platform based on slope gravity energy storage. Slope gravity energy storage is an energy storage form that uses the height difference of mountain slopes, underground inclined mines, or mine pit slopes to store and release electrical energy by lifting and lowering heavy objects on the slope. This invention mainly aims to solve the problem that existing conveyor vehicles cannot meet the requirements of slope gravity energy storage, thereby preventing heavy objects from sliding or tipping over due to the slope and improving the operational stability and safety of the gravity energy storage system.

[0023] Please see Figures 1 to 4 This utility model discloses a heavy object conveying and transfer platform based on slope gravity energy storage, comprising a main frame 1, with rotatable wheels 2 at the bottom of the main frame 1, for example, a total of four wheels 2. A top frame 3 is provided above the main frame 1, one end of which is rotatably connected to the main frame 1 (e.g., hinged), and the other end of which is connected to the main frame 1 via an angle adjustment device 4. The main frame 1 moves along the slope, changing angle with the slope gradient. The angle adjustment device 4 can adjust the angle between the top frame 3 and the main frame 1 to keep the top frame 3 horizontal. A lifting and transfer device 5 is provided above the top frame 3, and the upper surface of the lifting and transfer device 5 is a heavy object bearing surface capable of vertical lifting, horizontal extension, or horizontal transport.

[0024] Existing technologies use conventional transport vehicles, transporting heavy objects at an incline. With changes in slope and vibrations during operation, the heavy objects may slip or tip over. This new solution, however, places the heavy objects on a level load-bearing surface during incline operation, significantly improving operational stability. Furthermore, the lifting and transfer device in this solution effectively compensates for any height discrepancies between the platform and the external platform after the platform has come to a complete stop. Extension or conveying mechanisms allow for the automatic loading and unloading of heavy objects from and from the platform.

[0025] Specifically, in some embodiments, the lifting and transferring device 5 includes a vertical lifting assembly and a horizontal telescopic assembly connected together. One of the vertical lifting assembly and the horizontal telescopic assembly is connected to the top frame 3, and the upper surface of the other vertical lifting assembly and the horizontal telescopic assembly serves as a load-bearing surface. The horizontal telescopic assembly is, for example, a telescopic fork, which, in conjunction with the vertical lifting assembly, enables an automatic loading process, such as extending the unloaded fork, lifting the load, and moving it back to its original position, as well as an automatic unloading process, such as extending the fork and lowering the load.

[0026] In other embodiments, the lifting and transferring device 5 includes a vertical lifting assembly disposed above the top frame 3, and a conveying mechanism disposed above the vertical lifting assembly. The conveying mechanism is, for example, a chain or roller conveyor, thereby enabling the automatic feeding and unloading of heavy objects from the platform via a conveying method.

[0027] Preferably, the device further includes a load stabilizing device comprising two or more stabilizing blocks 6, which are located above the load-bearing surface and distributed around the periphery of the load 7. The stabilizing blocks 6 are connected to a movable mechanism to grip and release the load 7. The stabilizing blocks 6 are, for example, wear-resistant blocks. After the load is loaded, the multiple stabilizing blocks 6 grip the load 7, stabilizing its position and further preventing it from sliding or tipping over.

[0028] Furthermore, it can be defined that when the heavy object 7 is held tightly, the heavy object 7 is in the heavy object holding position, such as the central position above the top frame 3; above the heavy object bearing surface, the side where the heavy object 7 moves in and out of the heavy object holding position as the lifting and transferring device 5 horizontally extends or is horizontally transported is the heavy object entry and exit side; for example, in the illustrated embodiment, the side of the heavy object conveying and transferring platform with the wire rope connecting device 8 is the front side, and the heavy object conveying and transferring platform carrying the heavy object 7 moves in the front and back direction on the slope. After running to the top and bottom of the slope, the lifting and transferring device 5 drives the heavy object 7 to move to the right to unload the heavy object 7. This right side is the heavy object entry and exit side.

[0029] The movable mechanism connected to the stabilizing block 6 on the side where the heavy object enters or exits is an entry / exit clearance mechanism. This mechanism allows the stabilizing block 6 to rise, move, or flip to create the necessary space on the side where the heavy object 7 can move in and out. For example... Figure 4 In the illustrated embodiment, the entry / exit avoidance mechanism is a lifting mechanism, which lowers the stabilizing block 6 on this side without obstructing the extension and retraction of the lifting and transferring device. It is conceivable that the stabilizing block 6 on this side can also achieve the required avoidance function by moving forward or backward a sufficiently long distance, or by flipping downwards, etc. The specific mechanical structure is easily implemented based on existing technical knowledge and will not be elaborated here. Further preferably, the entry / exit avoidance mechanism also has a stabilizing block telescopic mechanism, enabling the stabilizing block 6 to extend towards the inside of the load-holding position and retract towards the outside of the load-holding position.

[0030] The movable mechanism connected to the stabilizing block 6 located on the other sides above the load-bearing surface is a stabilizing block telescopic mechanism. The stabilizing block telescopic mechanism can extend the stabilizing block 6 towards the inside of the load clamping position and retract it towards the outside of the load clamping position. Thus, when loading the load 7, after the load 7 is moved to the load clamping position in the middle, the stabilizing blocks 6 on the other sides (or all sides) except the load entry / exit side extend inward, abut against the load 7, and achieve clamping.

[0031] As a supplementary explanation, the lifting and transferring device 5 does not need to be very high. Therefore, the stabilizing block 6 can be set on the top frame 3 at the highest position above the load-bearing surface, so as not to obstruct the lifting and transferring device 5 from lifting and transferring. Alternatively, the stabilizing block 6 can also be set on the lifting and transferring device 5 and move up and down with it.

[0032] Preferably, the stabilizing blocks 6 are arranged in pairs, and there are at least four stabilizing blocks 6 evenly distributed around the periphery of the weight clamping position, with at least one stabilizing block 6 located on the weight entry / exit side. In the illustrated embodiment, the weight 7 is a cuboid, and there are four stabilizing blocks 6 evenly distributed around the periphery of the weight clamping position, corresponding to the four sides of the weight 7, with one stabilizing block 6 located on the weight entry / exit side.

[0033] The angle adjustment device 4 is, for example, a telescopic rod mechanism, more specifically, an electric cylinder. One end of the telescopic rod mechanism is rotatably connected to the top frame 3 (e.g., hinged), and the other end of the telescopic rod mechanism is rotatably connected to the main frame 1 (e.g., hinged). During operation, the telescopic rod mechanism extends, and the included angle between the top frame 3 and the main frame 1 increases.

[0034] Furthermore, it also includes a slope detection device and a control system. The slope detection device is connected to the control system, and the control system is connected to the angle adjustment device 4. For example, the slope detection device is fixedly mounted on the main frame and detects its own tilt angle, i.e., the slope of the ramp, in real time. When the angle changes, the angle adjustment device 4 is adjusted accordingly through calculation. Alternatively, the slope detection device is fixedly mounted on the top frame 3 and detects the levelness of the top frame 3 in real time. In other embodiments, programming is performed in advance based on the slope of the ramp to automatically adjust the levelness of the top frame 3 when the heavy object conveying and transfer platform moves to a certain position (its position can be determined by the running time).

[0035] Preferably, it also includes a power connection disconnection device for connecting to or disconnecting from an external power source, thereby connecting to an external power source for power supply during loading and unloading of heavy objects at the top and bottom of the slope, and / or charging the built-in power supply of the heavy object conveying and transfer platform. The power connection disconnection device can be, for example, a wired connection, such as that used in existing trolleybuses, or a wireless charging method, etc. Preferably, the heavy object conveying and transfer platform of this invention has a built-in power supply, which can be used to power the angle adjustment device and the detection devices on the platform (such as angle detection, limit detection, etc.) during operation.

[0036] As a more specific supplement, in the illustrated embodiment, a wire rope connecting device 8 is provided on the main frame 1, which in turn connects to a wire rope. The heavy-duty conveying and transfer platform is connected to the generator motor via the wire rope for energy conversion. In the illustrated embodiment, a track 9 is provided on the slope, and the wheels 2 are matched with the track 9, allowing the heavy-duty conveying and transfer platform to run along the track 9.

[0037] The working principle of a typical embodiment of this utility model is as follows.

[0038] During heavy object transport: During energy storage, the heavy object transport and transfer platform moves upward along the inclined track from the loading and unloading station at the bottom of the slope to the loading and unloading station at the top of the slope under the traction of the wire rope; during power generation, the heavy object transport and transfer platform moves downward along the track from the loading and unloading station at the top of the slope to the loading and unloading station at the bottom of the slope under the action of the heavy object and its own gravity; during operation, the angle adjustment device of the heavy object transport and transfer platform can adjust the angle between the top and bottom surfaces of the platform in real time according to the actual terrain of the slope to ensure that the top surface of the platform, i.e. the load-bearing surface of the heavy object, is always in a horizontal state.

[0039] Loading process: After the heavy load conveying and transfer platform comes to a stop at the loading / unloading station at the top or bottom of the slope, the power connection disconnection device connects to the nearby power source. The vertical lifting component of the lifting and transfer device at the top of the platform automatically adjusts to a uniform horizontal plane according to the height difference of its external platform. Then, the horizontal telescopic component extends to the external platform to wait for the heavy load to be lowered. Then, the horizontal telescopic component rises along with the vertical lifting component to lift the heavy load away from the external platform. The horizontal telescopic component retracts to the heavy load conveying and transfer platform and automatically falls to place the heavy load in the heavy load clamping position. Then, the stabilizing block on the side where the heavy load enters or exits rises, and at the same time, the stabilizing blocks on the other three sides move closer to the heavy load under the action of the stabilizing block telescopic mechanism until the heavy load is clamped from all sides. After that, the power connection disconnection device disconnects from the nearby power source, completing the loading of the heavy load.

[0040] Unloading process: After the heavy object conveying and transfer platform comes to a stop at the loading and unloading station at the top or bottom of the slope, the power connection disconnection device connects to the nearby power source. The stabilizing block on the side where the heavy object enters or exits descends and retracts. At the same time, the stabilizing blocks on the other three sides automatically move away from the heavy object. Then, the vertical lifting component of the lifting and transfer device lifts and raises the heavy object, and the horizontal telescopic component extends to send the heavy object to the external loading and unloading platform. The horizontal telescopic component lowers and retracts. After that, the power connection disconnection device disconnects from the nearby power source, completing the unloading of the heavy object.

[0041] The typical heavy object conveying and transfer platform based on slope gravity energy storage of this utility model has the following beneficial technical effects.

[0042] 1. Ordinary conveyor vehicles are mostly flatbed or box-type, used for transporting goods on level or gently sloping surfaces at relatively low speeds. They cannot meet the usage conditions and technical requirements of gravity energy storage. This utility model's heavy-duty conveying and transfer platform is a track-type platform with a wedge-shaped overall shape and wheels installed at the bottom for movement on inclined tracks. The top and bottom surfaces of this heavy-duty conveying and transfer platform form a certain angle. An angle adjustment device is installed between the top frame and the main frame to achieve balance adjustment of the heavy load. When the actual angle of the slope changes, the detection device can feed back the actual slope signal to the automatic control system. The automatic system issues a command to activate the angle adjustment device, which adjusts the angle between the top and bottom surfaces of the platform in real time according to the slope terrain, ensuring it always maintains the same angle as the slope. This keeps the top surface of the platform horizontal, preventing the heavy load from tilting during inclined conveying or transfer and effectively preventing downward slippage during operation, thus avoiding safety accidents.

[0043] 2. The platform is equipped with a lifting and telescopic mechanism at the top, responsible for loading, unloading, and transferring heavy objects. The lifting mechanism can effectively compensate for the height difference between the heavy object conveying and transfer platform and the external platform after the platform has come to a stop. The telescopic mechanism (such as telescopic forks) can automatically feed heavy objects into and out of the platform, reducing the working time of other heavy object transfer methods (such as crane grabbing) and improving system efficiency.

[0044] 3. Movable stabilizing blocks are installed at the top of the platform, forming an automatic stabilizing device for the heavy object. The stabilizing block on the side where the heavy object enters or exits is height-adjustable, while the other three sides are horizontally retractable. When the heavy object moves into position, the stabilizing block on the side where the heavy object enters or exits rises, while the stabilizing blocks on the other three sides move closer to the heavy object until they hug the heavy object from all sides.

[0045] 4. The platform is equipped with an automatic power connection device at the bottom. When the platform stops at the top or bottom of the slope, it can automatically connect to the power supply to power the telescopic devices and other electrical equipment installed on the platform. At the same time, it can charge the platform's built-in power supply, avoiding the increased cost caused by laying cables along the line.
