Description
Technical Field
[0001] The utility model belongs to the technical field of gravity energy storage power generation, and specifically relates to a multifunctional conveying dump truck suitable for a novel gravity energy storage conveying system. Background Art
[0002] Gravity energy storage is a technology that realizes the cyclic transformation of electrical energy, kinetic energy, and potential energy by lifting and falling heavy objects, thereby realizing the storage and release of electrical energy. The conveying system is the core system of the gravity energy storage power station. The quality of the conveying system design will directly determine the key indicators of the gravity energy storage power station, such as power, efficiency, and stability. In the gravity energy storage system, multiple heavy objects to be lifted or lifted will be stored in the upper warehouse and the lower warehouse (i.e., high-level and low-level sites or warehouses). When needed, the heavy objects will be transported to the lifting device through the conveying system in the upper warehouse and the lower warehouse (usually by means of a conveyor vehicle). For example, under the energy storage condition of the gravity energy storage power station, the conveyor vehicle in the lower warehouse needs to transport the heavy objects on the shelf to the loading and unloading area in an orderly manner according to the scheduling rhythm, and then the lifting system will transport the heavy objects to the loading and unloading area of the upper warehouse through the drop construction path, waiting for the conveyor vehicle in the upper warehouse to transport the heavy objects to the shelf for storage. The handover of heavy objects between the loading and unloading area and the conveyor vehicle is usually achieved through a conveyor on the loading and unloading area. The type and number of conveyor vehicles are determined according to the specific storage form and the conveying process design, and are usually completed by the cooperation of multiple handling equipment. The cost of a single conveyor vehicle is usually related to the load capacity, and the number of conveyor vehicles is related to the design of the storage system, scheduling arrangements, the maximum operating speed of the conveyor vehicle, the maximum acceleration, and the loading and unloading type. The conveyor vehicles of the current gravity energy storage system are usually combined with conveyors for unloading. After the conveyor vehicle arrives at the unloading point, the heavy objects are transported to the conveyor at the unloading point through the conveyor on the conveyor vehicle. This process is relatively slow. Utility Model Content

[0021] The utility model provides a multifunctional conveying dump truck suitable for a novel gravity energy storage conveying system, which solves the problems of low conveying efficiency in the prior art solutions and realizes the loading, unloading and transportation of heavy objects more flexibly and quickly.
[0022] See also Figures 1 to 3A multifunctional transport dump truck (abbreviated as transport truck, or transport truck) suitable for a novel gravity energy storage transport system according to one embodiment of the utility model comprises a transport truck body 1 having wheels. The transport truck body 1, for example, has a chassis and wheels located at both sides of the lower part of the chassis, and the wheels are, for example, at least four (two groups in front and back) to ensure smooth transport. A cargo space 4 for supporting heavy objects 5 is connected above the transport truck body 1 through a vertical adjustment hydraulic device 2 and a multidirectional adjustment hydraulic device 3. The vertical adjustment hydraulic device is located at one end of the front and rear ends of the transport truck body 1, and the multidirectional adjustment hydraulic device is located at the other end of the front and rear ends of the transport truck body 1. The vertical adjustment hydraulic device 2 is vertically arranged, and the multidirectional adjustment hydraulic device 3 is arranged with the upper end tilted toward one side of the vertical adjustment hydraulic device 2. The lower end of the vertical adjustment hydraulic device 2 is fixedly connected to the transport truck body 1, and the upper end of the vertical adjustment hydraulic device 2 is hingedly connected to the cargo space 4. The lower end of the multi-directional adjustment hydraulic device 3 is hingedly connected to the transport vehicle body 1, and the upper end of the multi-directional adjustment hydraulic device 3 is hingedly connected to the cargo position 4. Thus, by extending the vertical adjustment hydraulic device 2 and coordinating the extension and angle rotation of the multi-directional adjustment hydraulic device 3, the cargo position 4 can be vertically raised; by extending and rotating the multi-directional adjustment hydraulic device 3, the cargo position can be tilted and flipped.
[0023] More specifically, the upper warehouse and the lower warehouse are connected by a lifting passage (such as a shaft or a ramp, etc.), and the lifting passage is provided with a lifting device (such as a lifting container or other device for transporting heavy blocks). Both the upper warehouse and the lower warehouse have a loading and unloading area close to the lifting passage opening and a storage area relatively far from the lifting passage opening. The loading and unloading area is provided with a conveyor (which also has a buffering function), such as a roller conveyor, to assist in transporting the heavy blocks in and out of the lifting device, and the storage area is provided with a shelf for placing the heavy blocks. The conveyor vehicle is used for the transportation and loading and unloading process of the heavy blocks between the loading and unloading area and the storage area. Please refer to Figure 5 The conveying system includes a shelf 6, which includes two frames arranged side by side horizontally. The two frames are respectively located on both sides of the conveying route of the multifunctional conveying dump truck (conveyor truck) suitable for the new gravity energy storage conveying system of the utility model. The top of the two frames jointly supports the heavy object block 5, and the multifunctional conveying dump truck (conveyor truck) suitable for the new gravity energy storage conveying system is located below the heavy object block 5.
[0024] When the cargo position 4 is lowered, the upper surface of the cargo position 4 is lower than the upper surface of the shelf 6, and the transport vehicle can move in the space channel between the two racks and under the heavy blocks; after the cargo position 4 rises vertically, the upper surface of the cargo position 4 is higher than the upper surface of the shelf 6, so that the heavy blocks 5 can be lifted up, and then the heavy blocks 5 can move with the transport vehicle; conversely, when the cargo position 4 is loaded with heavy blocks 5, the cargo position 4 is lowered vertically, and the heavy blocks 5 can be placed on the shelf 6 for storage. At the loading and unloading area, the heavy blocks 5 transported out of the lifting device can be transported to the cargo position 4 by the conveyor; the transport vehicle carrying the heavy blocks 5 can be as shown. Figure 3 As shown in the figure, the heavy object block 5 is placed on the conveyor, and then the conveyor transports the heavy object block 5 to the lifting device. Therefore, preferably, the multi-directional adjustment hydraulic device 3 is located on the side of the conveyor vehicle that moves repeatedly relative to the storage area, and the vertical adjustment hydraulic device 2 is located on the side of the conveyor vehicle that moves repeatedly relative to the loading and unloading area, which is more convenient for controlling and stabilizing the force during the flipping and lifting process of the cargo position 4.
[0025] See also Figure 4 In a preferred embodiment, the upper surface of the cargo position 4 is a smooth flat plate (the thickness direction structure of the cargo position 4 is not shown in the attached drawings), and a friction block groove concave downward is provided on the upper surface of the cargo position 4, and a telescopic friction block 7 is arranged in the friction block groove, and the telescopic friction block 7 is connected to the bottom of the friction block groove by a lifting mechanism. After the heavy object block 5 is installed on the cargo position 4, the telescopic friction block 7 rises vertically, is flush with the upper surface of the cargo position 4, and then contacts the bottom surface of the heavy object block 5, thereby strengthening the friction between the heavy object block 5 and the cargo position 4, preventing the heavy object block 5 from sliding when the conveying vehicle accelerates and decelerates, and ensuring the stability when conveying the heavy object block. When the cargo position 4 is turned over to unload, the telescopic friction block 7 drops vertically and breaks away from the contact with the heavy object block 5, which facilitates the sliding down and unloading of the heavy object block. Preferably, the telescopic friction block 7 is arranged at four positions near the four corners on the upper surface of the conveying vehicle body 1, so as to achieve a better anti-slip effect through a relatively small contact area of the telescopic friction block 7, and matches the rectangular heavy object block.
[0026] Preferably, see Figure 5 and Figure 2 , Figure 3, the vertical adjustment hydraulic device 2 and the multi-directional adjustment hydraulic device 3 are both arranged near the two sides of the transport vehicle body 1, so that they are stably connected and supported through the four connection points at the bottom of the cargo space 4. Furthermore, the two hydraulic devices on both sides are linked and controlled in a consistent manner. For example, the vertical adjustment hydraulic device 2 and / or the multi-directional adjustment hydraulic device 3 are hydraulic rods (or hydraulic cylinders), and the two ends of the hydraulic rods connected to the transport vehicle body 1 and the cargo 4 are the cylinder body and the piston rod, respectively. In addition, the distance between the vertical adjustment hydraulic device 2 and the multi-directional adjustment hydraulic device 3 is appropriate to the size of the transport vehicle body 1 and the cargo 4, and the connection point is roughly located near the wheels at the bottom of the transport vehicle body 1, thereby ensuring that in the case of Figure 2 , Figure 3 During the working process shown, the structure can remain stable.
[0027] Preferably, the hinge at the lower end of the multi-directional adjustable hydraulic device 3 has a locking mechanism, for example, an existing electric lock supporting structure, or a braking mechanism at the rotating shaft of the hinge structure, etc., which has a locking function and can fix the locking angle after the multi-directional adjustable hydraulic device 3 is adjusted, thereby further ensuring the structural strength when carrying heavy objects.
[0028] At present, the most common gravity energy storage conveying system for transporting heavy objects is to use heavy-duty AGV (automatic guided vehicle) or RGV (rail-guided vehicle) carts for transportation. The conveying vehicle body 1 of this scheme can also be selected as an AGV transport vehicle or an RGV transport vehicle; in other words, the conveying vehicle of the utility model can be modified using these existing forms, and the driving method, related components, etc. of the conveying vehicle can use mature existing technologies.
[0029] The main concept and beneficial technical effects of the utility model are as follows. The gravity energy storage power station realizes the conversion of gravitational potential energy and electric energy by lifting and lowering heavy objects, and the gravitational potential energy of heavy objects is the source of power generation. In addition, the power and capacity of the gravity energy storage power station must reach a certain value to have practical application significance, so the single mass of the heavy objects is usually very large, ranging from tens of tons to hundreds of tons, and the handling equipment must also reach the ability of overload. Usually, the cost of handling equipment is also very high, so the design requirement of the conveying system is to complete the dispatch of heavy objects safely at the lowest cost. The cost of a single conveyor is usually related to the load capacity, and the number of conveyors is related to the design, dispatching arrangement, maximum operating speed, maximum acceleration, and loading and unloading type of the warehousing system. The current gravity energy storage system conveyor is usually combined with a conveyor for unloading. After the conveyor arrives at the unloading point, the heavy objects are transported to the conveyor at the unloading point by the conveyor on the conveyor, and the process speed is slow. Therefore, the utility model designs a new type of conveying dump truck, which has the functions of vertical lifting and multi-angle oblique flexible loading and unloading through the adjustment of the front and rear hydraulic devices, so that the loading, unloading and transportation of heavy blocks can be flexibly and quickly realized. When loading heavy blocks, the conveying vehicle drives to the bottom of the heavy block shelf, and the cargo position is vertically lifted to lift the heavy objects. When the heavy blocks are separated from the shelf, the conveying vehicle starts to speed up the transportation; when unloading heavy blocks, the conveying vehicle transports the heavy blocks to the loading and unloading area, and adjusts the rotating cargo position through the front and rear hydraulic devices to realize the sliding unloading of the heavy blocks, and can start in the reverse direction to the storage area while flipping one side of the cargo position, thereby reducing the unloading time and improving the efficiency of the conveying system.
