Description

Technical Field

[0001] This invention relates to the field of gravity energy storage unmanned freight elevator system technology, and in particular to a lifting and lateral movement storage system. Background Technology

[0002] Gravity energy storage power generation systems require the lifting and transport of heavy objects. To enable the large-scale lifting of heavy objects from low to high positions and their sequential placement, a lifting system is needed. This system should be able to lift / lower heavy objects and, through a lateral movement system, place them onto load-bearing beams at high / low positions. The system must possess the capabilities for lifting / lowering heavy objects, lateral movement, and precise lateral positioning.

[0003] For example, patent application CN202021728621.9, entitled "A Freight Elevator-Type Lifting Platform," discloses a modular lifting rail transport vehicle, including a ladder frame and a lifting platform. The ladder frame is equipped with a power unit for controlling the lifting of the lifting platform. The lifting platform is equipped with several fixing mechanisms for fixing the position of the lifting platform. The ladder frame is equipped with several guide rods, and the side wall of the lifting platform is equipped with several guide frames. Guide wheels are installed inside the guide frames. One side of the guide wheel abuts against the side wall of the guide rod and rolls with the guide rod. The lower end of the lifting platform is equipped with several power shafts. The output shaft of the power shaft is equipped with a stabilizing rod. The power shaft is used to push the stabilizing rod to move. Several rollers are sleeved on the stabilizing rod. The rollers abut against the ladder frame and roll with the ladder frame, enabling stable movement of the lifting platform.

[0004] However, in the existing technology, the lifting platform does not have a lateral movement device, and a simple lateral movement device is prone to instability when moving heavy objects. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting and lateral moving storage system in which the lifting traction of the lifting freight elevator is connected to the lateral moving device, and the traction force is always vertical through the top pulley, ensuring the stability of the lifting and lateral moving process.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A lifting and lateral moving storage system is installed in a building structure, which includes a lifting platform. The lifting platform comprises a laterally moving main frame for supporting heavy objects.

[0008] The building structure is also equipped with a traction lifting device, a trolley lateral movement drive and a top travel track. The top travel track is located above the lifting platform and parallel to the lateral movement direction of the main frame. A top pulley is connected to the top travel track, and the trolley lateral movement drive drives the top trolley to move laterally along the top travel track.

[0009] The traction lifting device is used to pull the wire rope. One end of the wire rope goes up over the top pulley and then down to connect to the main frame.

[0010] Furthermore, the top pulley vehicle includes a chassis frame that slides along the top travel track. A front fixed pulley is connected to the side of the chassis frame near the lifting platform, and a boom is also hinged to this side. A swing drive component that drives the boom to swing up and down is connected to the chassis frame. The free end of the boom is connected to a rear fixed pulley. The wire rope passes through the rear fixed pulley and the front fixed pulley in sequence and is then connected to the main frame.

[0011] Furthermore, the swing drive includes a lifting cylinder hinged to the chassis frame, with the free end of the lifting cylinder hinged to the upper lifting arm and the lower lifting arm, the other end of the upper lifting arm hinged to the boom, and the other end of the lower lifting arm hinged to the chassis frame.

[0012] Furthermore, the trolley lateral movement drive includes a lateral movement cylinder, one end of which is connected to the top pulley trolley, and the other end is connected to a fixed pile, which is fixed in the building structure.

[0013] Furthermore, the traction lifting device includes a ground winch, which pulls the lifting and lowering of the freight elevator.

[0014] Furthermore, the building structure is also connected to a top fixed pulley and a counterweight that moves up and down. The end of the wire rope away from the lifting platform passes through the ground winch, goes upward, goes around the top fixed pulley, and then connects downward to the counterweight.

[0015] Furthermore, the building structure is connected to a vertical counterweight guide rail, and the counterweight blocks slide up and down and are connected to the counterweight guide rail.

[0016] Furthermore, the wire rope includes a freight elevator rope, a counterweight rope, and a connector between them. The end of the freight elevator rope is connected to the lifting freight elevator, and the end of the counterweight rope is connected to the counterweight block. During the lifting and lowering of the counterweight block, the connector is always located between the ground winch and the counterweight block.

[0017] Furthermore, the connector includes a middle connecting plate, an upper connecting plate for connecting the counterweight rope, and a lower connecting plate for connecting the freight elevator rope. An upper connecting piece is connected between the upper connecting plate and the middle connecting plate, and a lower connecting piece is connected between the lower connecting plate and the middle connecting plate.

[0018] Furthermore, the building structure is connected to a freight elevator track for guiding the freight elevator up and down, the main frame is horizontally slidably connected to the freight elevator track, and the freight elevator is also connected to several hydraulic cylinders for driving the main frame to slide.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. This invention relates to a combined system with pulleys for lateral movement and lifting, primarily addressing the need for lifting, transporting, and sequentially placing heavy objects in gravity energy storage power generation systems. Gravity energy storage systems require high-speed vertical lifting of objects exceeding 20 tons and the ability to sequentially place them on load-bearing beams at different floor levels. The system must possess the functions of lifting / lowering heavy objects, lateral movement of heavy objects, and precise lateral positioning.

[0021] 2. The system designed in this invention consists of three parts: a ground winch traction machine, a lateral lifting machine, and a top lateral pulling cart. The lateral lifting machine has the function of lifting and lowering along a vertical track and moving heavy objects laterally along a horizontal track. The top pulling cart has the function of lifting, lowering, and moving heavy objects laterally. The ground winch traction machine has the function of winch traction.

[0022] 3. In this invention, the lifting platform is raised and lowered by a ground hoisting mechanism via a steel wire rope / traction belt on a top pulley trolley. The lifting platform runs along a vertical guide rail. When the lifting platform stops at the target floor, the load support frame is moved laterally by the platform's built-in lateral movement device. During this process, the top pulley trolley and the lifting platform's load support frame move synchronously to eliminate the lateral tension component of the traction belt (when the top pulley trolley and the lifting platform move synchronously, the traction belt is always perpendicular to the horizontal plane, so the lateral force of the traction belt is 0).

[0023] 4. The top pulley trolley has a built-in lifting function. When the freight elevator stops at the target floor, the lifting arm cylinder on the top pulley trolley retracts, causing the boom to lower, which in turn lowers the freight elevator, placing the load onto the load-bearing beam. The lifting function of the top pulley trolley allows for precise control of the freight elevator's height. Furthermore, the large lifting range of the pulley trolley can compensate for changes in the length of the wire rope / traction belt caused by changes in traction weight before and after unloading the load.

[0024] This invention comprises a three-part system capable of high-speed lifting and lateral movement of heavy objects, making it suitable for applications requiring frequent lifting and lowering of heavy loads. The system employs a traction-type hoisting mechanism, offering advantages such as simple structure and low cost, making it particularly suitable for applications in gravity energy storage and industrial material handling.

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on the present invention.

[0033] A lift-and-shift storage system, such as Figure 1 As shown, it is installed in the building structure 7. The building structure 7 has several layers of load-bearing beams 8 and several lifting elevators 2 located on one side of the load-bearing beams 8. The lifting elevator 2 includes a main frame that moves laterally. The main frame is used to carry heavy objects 10. The lifting elevator 2 moves up and down, frequently lifting and placing the heavy objects 10 on the load-bearing beams 8 at different heights.

[0034] like Figure 1 and Figure 2 As shown, the building structure 7 is connected to a freight elevator track 5 for guiding the lifting and lowering of the freight elevator 2. The freight elevator 2 is connected to a guide wheel assembly that moves along the freight elevator track 5 and can be driven up and down in the freight elevator track 5 by a steel wire rope pulled from the top. The main frame is horizontally slidably connected to the freight elevator track 5. The freight elevator 2 is also connected to several hydraulic cylinders for driving the main frame to slide, so as to realize its lateral movement function. When the hydraulic cylinders are extended, the base of the freight elevator 2 remains stationary, while the main frame carrying the heavy object 10 moves laterally together with the heavy object 10. Several hydraulic cylinders for driving the heavy object 10 to lift or place the heavy object 10 between the load beams 8 can also be connected to the main frame to lift or place the heavy object 10 between the load beams 8. Its specific structure can be a lifting elevator with a hydraulic lateral movement device as described in the patent application number CN202210585668.1, to realize its lifting and lateral movement functions.

[0035] like Figure 1 and Figure 2As shown, the building structure 7 is equipped with a traction lifting device, a trolley lateral movement drive and a top travel track 112. The top travel track 112 is located above the lifting platform 2 (fixed to the top of the building structure 7) and parallel to the lateral movement direction of the main frame. The top pulley trolley 1 is connected to the top travel track 112. The trolley lateral movement drive drives the top trolley to move laterally along the top travel track 112.

[0036] like Figure 3 As shown, the lateral movement drive includes a lateral movement cylinder 106, one end of which is hinged to the top pulley 1 and the other end is hinged to a fixed pile 111, which is fixed in the building structure 7. When the lateral movement cylinder 106 extends or retracts, the top pulley 1 will move horizontally along the top travel track 112.

[0037] like Figure 1 and Figure 2 As shown, the traction lifting device is used to pull the wire rope 11. One end of the wire rope 11 goes up over the top pulley 1 and then down to the main frame of the lifting platform 2.

[0038] In this invention, both the top pulley trolley 1 and the lifting platform 2 are equipped with a lateral movement system. When the traction lifting device drives the lifting platform 2 to the target floor, the lateral movement hydraulic cylinder on the lifting platform 2 extends, while the lateral movement cylinder 106 on the top pulley trolley 1 retracts. The main frame of the lifting platform 2 then moves forward carrying the load 10, and the top pulley trolley 1 moves forward along the top travel track 112 at the same speed. At this time, the steel cable 11 above the lifting platform 2 remains vertical. This control mode ensures that when the lifting platform 2 laterally moves the load 10, it only needs to overcome the horizontal acceleration reaction force of the load 10, effectively reducing the horizontal component force on the platform track 5. Simultaneously, this synchronous movement of the top pulley trolley 1, the main frame, and the load 10 avoids the load 10 from tipping over due to the swinging motion of the load 10 and the lifting platform 2 during acceleration and deceleration.

[0039] like Figure 3 As shown, the top pulley vehicle 1 includes a chassis frame 102 connected to a transverse hydraulic cylinder 106. The chassis frame 102 slides along the top travel track 112 via the front wheel 104 and the rear wheel 103 at the bottom, causing it to move back and forth.

[0040] The chassis frame 102 is connected to a front fixed pulley 110 on the side near the lifting platform 2. The boom 101 is also hinged to this side. A swing drive is connected to the chassis frame 102 to drive the boom 101 to swing up and down. The free end of the boom 101 is connected to a rear fixed pulley 109. The wire rope 11 passes through the rear fixed pulley 109 and the front fixed pulley 110 in sequence before being connected to the main frame.

[0041] like Figure 3As shown, the swing drive includes a lifting cylinder 105 hinged to the chassis frame 102. The free end of the lifting cylinder 105 is hinged to the upper lifting arm 107 and the lower lifting arm 108. The other end of the upper lifting arm 107 is hinged to the boom 101, and the other end of the lower lifting arm 108 is hinged to the chassis frame 102.

[0042] When the lifting cylinder 105 extends, it pushes the hinge point of the upper lifting arm 107 and the lower lifting arm 108, thereby raising the boom 101 upward and causing the rear fixed pulley 109 to rise along with the boom 101.

[0043] This system can achieve precise vertical lifting of heavy objects 10, and can also overcome the vertical positioning error caused by the elastic deformation of the ultra-long steel wire rope 11 under different load conditions.

[0044] Specifically, in ultra-high-rise buildings (such as gravity energy storage systems exceeding 150 meters in height), the total length of the steel wire rope 11 exceeds 400 meters. Furthermore, unlike ordinary elevators, the weight of the load 10 on the freight elevator 2 in this system is far greater than the counterweight and the freight elevator 2's own weight. Therefore, the absolute difference in the total length of the steel wire rope 11 between when the freight elevator 2 is empty and fully loaded is significant (1-2 meters), which has a very adverse effect on the precise positioning of the freight elevator 2 on different floors.

[0045] In this invention, when it is necessary to place the heavy object 10 on the load-bearing beam 8 of the building, the traction lifting device remains stationary, while the lifting cylinder 105 on the top pulley trolley 1 performs the retraction or extension action; when the lifting platform 2 places the heavy object 10 on the beam (or lifts the heavy object 10 from the beam), the lifting cylinder 105 retracts, and the boom 101 drives the rear fixed pulley 109 to descend; since the traction lifting device is stationary, the static friction between the traction lifting device and the wire rope 11 can ensure that the wire rope 11 passing over the traction lifting device does not slip at this time; since the extension amount of the lifting cylinder 105 can be precisely controlled, the height of the lifting platform 2 can be precisely controlled;

[0046] Furthermore, when the freight elevator 2 descends, since the width of the load 10 is greater than the spacing of the load beam 8, the load 10 will fall onto the load beam, and then the contact between the freight elevator 2 and the load 10 will be released, and the weight of the load 10 on the freight elevator 2 will be unloaded; since the tension on the wire rope 11 is also greatly reduced, the length of the wire rope at the top of the freight elevator 2 is shortened. Therefore, in order for the freight elevator 2 to descend and separate from the load 10, the descent distance of the rear fixed pulley 109 must be much greater than the distance from which the load 10 descends to the load beam 8.

[0047] The top pulley trolley 1 in this invention enables precise and smooth height control of the lifting platform 2 during the lifting or lowering of the load 10. If conventional winches, such as those located on the ground or building roof, are used for height control, the insufficient control precision of the winch can easily lead to the lifting platform 2 not stopping properly or excessive impact when the load 10 is placed or lifted.

[0048] like Figure 1 As shown, the traction lifting device includes a ground winch 3 (other traction machines can also be selected), which pulls the lifting of the freight elevator 2. The building structure 7 is also connected to a top fixed pulley 14 and a counterweight 4 that moves up and down. The end of the wire rope 11 away from the freight elevator 2 passes through the ground winch 3 and goes up, then around the top fixed pulley 14 and down to the counterweight 4.

[0049] The building structure 7 is connected to a vertical counterweight guide rail 6, and the counterweight block 4 slides up and down and is connected to the counterweight guide rail 6.

[0050] In this invention, one end of the steel wire rope 11 used to pull the lifting platform 2 is connected to the top of the main frame of the lifting platform 2, and then passes in sequence around the front fixed pulley 110, the rear fixed pulley 109 on the pulley cart, the drive shaft on the ground winch 3, and the top fixed pulley 14, and the end is connected to the counterweight block 4.

[0051] like Figure 1 and 2 As shown, the wire rope 11 includes a freight elevator rope 1101, a counterweight rope 1102 and a connector 1103 between them. The end of the freight elevator rope 1101 is connected to the lifting freight elevator 2, and the end of the counterweight rope 1102 is connected to the counterweight block 4. During the lifting and lowering of the counterweight block 4, the connector 1103 is always located between the ground winch 3 and the counterweight block 4.

[0052] like Figure 4 As shown, connector 1103 includes a middle connecting plate 1106, an upper connecting plate 1104 for connecting the counterweight rope 1102, and a lower connecting plate 1108 for connecting the freight elevator rope 1101. An upper connecting piece 1105 is connected between the upper connecting plate 1104 and the middle connecting plate 1106, and a lower connecting piece 1107 is connected between the lower connecting plate 1108 and the middle connecting plate 1106. The number of wire ropes 11 connected to the upper connecting plate 1104 and the lower connecting plate 1108 can be configured according to different load requirements.

[0053] This system employs the traction principle. When the lifting platform 2 is loaded with a load 10 and the entire system remains stationary or operates at a constant speed, the weight of the lifting platform 2 and the load 10 is equal to the friction between the drive wheel and the wire rope 11 plus the weight of the counterweight 4. The drive shaft on the winch is a traction sheave, which has friction with the wire rope 11 (or an elevator traction belt) winding around it. When the drive shaft rotates, it drives the wire rope 11, which in turn moves the lifting platform 2 and the counterweight 4 up and down. When the lifting platform 2 is unloaded, its weight is the same as the counterweight 4. When the lifting platform 2 is fully loaded, the tension balance is achieved by the friction between the drive wheel and the wire rope 11.

[0054] Therefore, when the freight elevator 2 is fully loaded, the tension on the wire rope 11 between the drive shaft on the winch and the freight elevator 2 is much greater than the tension between it and the counterweight 4. Therefore, this system divides the wire rope 11 into two parts, which are connected by a connector 1103. The length of the counterweight rope 1102 ensures that when the counterweight 4 moves between the bottom and top floors of the building, the connector 1103 is always located on the side where the ground winch 3 connects to the counterweight 4, and will not contact the ground winch 3. In this way, the number of wire ropes 11 of the freight elevator rope 1101 can be configured to meet the heavy load requirements of the system, while the number of wire ropes 11 of the counterweight rope 1102 only needs to be sufficient to safely lift the counterweight 4, which can save a lot of wire rope 11 costs and reduce the system weight.

[0055] This invention designs a combined system with pulleys for lateral movement and lifting, primarily addressing the need for lifting, transporting, and sequentially placing heavy objects (10) in gravity energy storage power generation systems. The gravity energy storage system requires high-speed vertical lifting of heavy objects (10) exceeding 20 tons, and the ability to sequentially place them on load-bearing beams (8) at different floor levels. The system requires the ability to lift / lower heavy objects (10) with large mass, lateral movement of the heavy objects (10), and precise lateral positioning. Furthermore, the required lifting and lateral movement system must be simple in structure, low in cost, and capable of automatically loading and unloading heavy objects (10).

[0056] Its lifting platform 2 can lift and laterally move large-sized heavy objects 10, and can laterally move the heavy objects 10 and place them on a dedicated crossbeam. The system designed in this invention consists of three parts: a ground winch traction machine, a lateral lifting platform, and a top lateral transfer pulley trolley. The lateral lifting platform has the function of lifting along a vertical track and laterally moving the heavy objects 10 along a horizontal track. The top pulley trolley 1 has the function of traction lifting and lateral movement of the heavy objects 10, and the ground winch traction machine has the function of winch traction. The system composed of these three subsystems can realize the high-speed lifting and lateral movement of the heavy objects 10, and is suitable for occasions where the heavy objects 10 are frequently lifted and moved. This system adopts traction hoisting, which has the advantages of simple structure and low cost, and is particularly suitable for gravity energy storage, industrial handling and other fields.

Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
