Description

Technical Field

[0001] The present invention relates to the technical field of slope track type gravity energy storage, and in particular to a track connecting and conveying device. Background Art

[0002] Inclined track-based gravity energy storage technology utilizes elevation differences to convert gravitational potential energy, converting mechanical energy into electrical energy through generators and motors. It is an innovative physical energy storage solution. The system architecture comprises three main components: an upper stack, an inclined track, and a lower stack, integrated with three key subsystems: a heavy-weight block transport system, a docking and sorting system, and a loading and unloading and stacking system. To address the challenges of complex mountainous environments and limited construction space, the heavy-weight block transport system breaks away from traditional design by adopting a separate power solution and inventive use of chain drive technology. Chain drive boasts a compact structure, high transmission efficiency, and strong adaptability. The chain-driven track trolley smoothly and efficiently transports heavy loads at low speeds within confined spaces. The docking and sorting system integrates a multi-dimensional motion mechanism, including ramp and horizontal track connection, chain drive, and trolley lifting and traversing functions, ensuring the precise and rapid transfer of energy storage blocks between different levels and locations. The loading and unloading and stacking system utilizes automated overhead cranes and a robust, maintenance-free steel frame structure, enabling efficient and safe loading and unloading, as well as orderly stacking of the blocks. In general, the slope track gravity energy storage system has greatly improved the energy storage efficiency and environmental adaptability with the help of chain drive technology innovation and intelligent docking, loading and unloading and sorting design, especially demonstrating its technological leadership and practicality in complex terrain and confined space applications.

[0003] Current sloped track gravity energy storage systems present significant challenges in connecting trolleys between horizontal tracks. Although each track utilizes a chain drive to independently drive the trolleys, power is interrupted when the trolleys switch between tracks, requiring additional power from the connecting track to facilitate their movement. The current design fails to utilize the trolley's inertia, requiring additional power units for each track switch, increasing operating costs and reducing energy efficiency. Therefore, there is an urgent need to develop new connection technologies that leverage trolley inertia and reduce reliance on external power to improve system efficiency and cost-effectiveness.

[0036] Example 1

[0037] Reference Figure 1-Figure 5, which is the first embodiment of the present invention, provides a track connecting and conveying device, including a connecting component 100, including a frame 101 and a lifting component 102 installed on the frame 101, and a rotating component 103 installed on the upper end of the lifting component 102; a receiving component 200, which is installed on the connecting component 100, and includes a receiving shell 201 installed on the rotating component 103, and the receiving shell 201 is provided with two symmetrical groups of conveyor belts 202 for receiving the transport trolley inside, and a frame 203 is also rotatably provided inside the receiving shell 201, and the second rotating shaft 203 of the frame 203 A connecting rod 206 is provided on a for driving the lower half of the conveyor belt 202 to lift up; a force storage component 300 is installed in the receiving component 200, which includes a force storage component 301 installed in the receiving shell 201, and a ratchet and ratchet component 302 for controlling its unidirectional force storage is provided on the force storage component 301, and an input bevel gear 303 is provided above the ratchet and ratchet component 302, and two output bevel gears 304 are symmetrically provided above the input bevel gear 303, and the output bevel gear 304 is meshed with the toothed belt 202b lifted by the conveyor belt 202 through a rotating rod 305 and a second gear 306.

[0038] In this embodiment, the connecting component 100 includes a frame 101, a lifting component 102 and a rotating component 103, wherein the height is adjusted by the lifting component 102, and the rotating component 103 ensures the flexible rotation of the connecting component 100 at different angles. Two sets of conveyor belts 202 are symmetrically arranged inside the rotatable receiving shell 201 on the receiving component 200, which are specially used for stable bearing and connecting the transport trolley. A rotatable frame 203 is also provided in the receiving shell 201, and a connecting rod 203a is installed on the second rotating shaft 203a. Rod 206 and rotating drum 205 can drive the lower half of conveyor belt 202 to lift when the transport trolley enters, achieving docking of the trolley and transmission of power. A ratchet and ratchet member 302 is provided above the power storage member 301 in the power storage component 300 to control unidirectional energy storage. Two output bevel gears 304 are symmetrically arranged above the ratchet and ratchet member 302. These two output bevel gears 304 are respectively engaged with the toothed belt 202b raised by the conveyor belt 202 through the rotating rod 305 and the second gear 306. This means that no matter which side of the receiving shell 201 the transport trolley enters from, power can be effectively transmitted to the corresponding output bevel gear 304 through the toothed belt 202b, and the kinetic energy of the trolley's movement can be converted into potential energy of the power storage member 301. The ratchet and ratchet parts 302 ensure that energy can only be accumulated in one direction, and the energy can be released in the opposite direction when needed through the unlocking mechanism, ensuring that the system continues to operate efficiently, improving energy utilization efficiency, reducing pause time, ensuring the continuous operation performance of the system, and realizing the functions of two-way power transmission and energy storage.

[0039] In addition, the connecting rod 206, rotating drum 205 and frame 203 structure of the present application can adjust the meshing state of the toothed belt 202b and the second gear 306 in real time according to the entry direction and position of the transport trolley, thereby ensuring that no matter which side of the track the trolley enters from, it can drive the force storage member 301 to store energy. At the same time, the rotating frame 203 can adaptively intercept and stop the transport trolley in inertial motion during the docking process, reflecting a powerful adaptive docking capability. This intelligent and flexible design not only optimizes energy utilization, but also greatly improves the docking efficiency, so that the device can efficiently and smoothly complete the docking and transfer of the transport trolley between tracks under various complex working conditions.

[0040] Example 2

[0041] Reference Figure 5-Figure 9 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that two sets of support legs 204 are symmetrically arranged on the upper surface of the receiving shell 201. One set of support legs 204 corresponds to one conveyor belt 202, and each set of support legs 204 has three support legs. Two support legs 204 are located at either end of the conveyor belt 202, and are used to mount the first gears 202a at both ends of the conveyor belt 202. A toothed belt 202b is provided between the two first gears 202a. A support plate 202c is provided at the upper side of the toothed belt 202b. The support plate 202c is fixed to the receiving shell 201 and is used to support the upper side of the toothed belt 202b, assisting it in bearing the weight and supporting the transport trolley. The remaining support leg 204 of the same set is provided at the midpoint of the conveyor belt 202. The rotating rod 305 of the output bevel gear 304 is rotatably set on the support leg 204 located at the midpoint, and the second rotating shaft 203a located on the frame 203 is rotatably set on the support leg 204. The second rotating shaft 203a and the frame 203 are fixedly connected. The second rotating shaft 203a is provided with a torsion spring for restoring the balance of the frame 203. The second rotating shaft 203a is provided with a connecting rod 206, and the lower end of the connecting rod 206 is provided with a rotating drum 205. The rotating drum 205 is located on the lower surface of the toothed belt 202b of the conveyor belt 202, and a second gear 306 is provided on the rotating rod 305 to engage with the toothed belt 202b. An input bevel gear 303 is fixedly connected above the ratchet 302a, and the input bevel gear 303 is rotatably connected to the receiving shell 201 through bearings and brackets. The two output bevel gears 304 are respectively the first output bevel gear 304a and the second output bevel gear 304b, and the first output bevel gear 304a is transmission connected to one of the conveyor belts 202, and the second output bevel gear 304b is transmission connected to the other conveyor belt 202. The first output bevel gear 304a and the second output bevel gear 304b are symmetrically arranged on the input bevel gear 303.

[0042] Please refer to the following for details: Figure 3 In order to highlight the bottom of the transport trolley, Figure 3 The transport trolley in the figure has been lifted to a certain extent. In fact, since the transport trolley needs to match the chains transported by the front and rear horizontal rails, a protrusion that matches the chain is set on its bottom surface. When the protrusion moves between the horizontal rail and the connecting rail, it presses down the end of the frame 203 located in the gap between the two rails, so that the frame 203 can perform a lever movement. At the same time, with the action of inertia, the bottom of the transport trolley will move to the toothed belt 202b. Due to the static friction between the bottom and the toothed belt 202b and the weight of the transport trolley, the transport trolley and the toothed belt 202b are stationary, so that the transport trolley drives the toothed belt 202b to move in the forward direction, so that the toothed belt 202b rotates until the transport trolley is blocked by the frame 203 with the front end tilted up.

[0043] Furthermore, regarding how to achieve the effect of static friction between the bottom of the transport trolley and the surface of the toothed belt 202b, (1) a. Select materials with a high friction coefficient: such as rubber or silicone coating: These two materials naturally have a high friction coefficient and are suitable for coating the bottom of the transport trolley, which can significantly increase the friction when in contact with the belt. b. Polyurethane (PU) covering layer: Polyurethane material is wear-resistant and tear-resistant, and the hardness and friction coefficient can be adjusted as needed, making it an excellent choice for improving friction. c. Carbon fiber reinforced plastic (CFRP): Although the cost is relatively high, CFRP has the characteristics of high strength and low weight. The friction performance can be further increased through surface treatment. 2) Add anti-slip texture: a. Directly process fine anti-slip textures or bumps on the bottom of the transport trolley. These structures can increase the contact area at the microscopic level, thereby improving friction. b. For heavy loads or special requirements, hard metal particles or anti-slip spikes can be embedded in the contact surface to enhance grip, but care should be taken not to damage the belt. c. Covering with anti-slip pads or belts: such as self-adhesive anti-slip pads: There are many kinds of ready-made self-adhesive anti-slip pads on the market, such as PVC and TPU materials. These pads have strong glue on the back and can be directly attached to the bottom of the transport trolley, which is convenient and quick. Such as replaceable anti-slip strips: When designing the transport trolley, grooves are reserved, and removable anti-slip strips or belts can be inserted, which is convenient for replacement after wear. It is also convenient to choose anti-slip strips of different materials according to different working conditions. 3) Chemical treatment: a. Surface roughening treatment: The bottom of the transport trolley is roughened by sandblasting, acid etching and other methods to increase the surface roughness and thus increase the friction coefficient. b. Anti-slip coating: There are special anti-slip coatings on the market, such as resin-based or rubber-based coatings, which can form a layer of high friction surface after curing after spraying. Furthermore, a tooth groove can be set on the upper surface of the toothed belt 202b, and this tooth groove is plugged into the protrusion on the bottom of the transport trolley, so that the transport trolley can remain stationary between the toothed belt, and the transport trolley drives the toothed belt to rotate.

[0044] The detailed usage process of this part is as follows: when the transport trolley enters from one side of the receiving shell 201, its weight will press down on one side of the frame 203. Through the cooperation of the connecting rod 206 and the rotating drum 205, the movement of the frame 203 can drive the toothed belt 202b on the left to engage with the corresponding second gear 306. Once the engagement is successful, the second gear 306 on the left will start the first output bevel gear 304a to rotate forward under the transmission of the rotating rod 305. The first output bevel gear 304a then drives the input bevel gear 303 to rotate, and the input bevel gear 303 is coaxially arranged with the ratchet 302a, so that the force storage member 301 can accumulate and store energy, that is, the force storage process. When the force storage member 301 needs to release energy and push the transport trolley in the opposite direction, the force storage member 301 drives the input bevel gear 303 and the first output bevel gear 304a to reverse through the ratchet 302a. The reversed first output bevel gear 304a acts on the second gear 306 on the left again through the rotating rod 305, causing the left toothed belt 202b to reverse, and finally pushing the transport trolley in the opposite direction.

[0045] Similarly, when the transport trolley enters from the other side of the receiving shell 201, the same downward pressure acts on the other side of the frame 203, and the connecting rod 206 and the rotating drum 205 cooperate with the rotation of the frame 203. This time, the right toothed belt 202b is driven to engage with the second gear 306 on the right. The second gear 306 on the right drives the second output bevel gear 304b to rotate under the transmission of the rotating rod 305. Then, as in the above process, the second output bevel gear 304b will also drive the input bevel gear 303 to rotate, and then drive the force storage member 301 to store force through the ratchet 302a. In the force release stage, the force storage member 301 also drives the input bevel gear 303 and the second output bevel gear 304b to reverse through the ratchet 302a, and then reverses the right second gear 306 and the right toothed belt 202b through the rotating rod 305, thereby pushing the transport trolley out in the opposite direction.

[0046] In short, the purpose of this system design is to ensure that no matter which side the transport trolley enters the receiving shell 201, the power can be effectively transmitted to the power storage member 301 through the corresponding transmission member for storage or release, and the transport trolley can be smoothly and efficiently transferred from either side to the next section of the track as needed.

[0047] Regarding how the system automatically selects the appropriate power transmission path based on the direction and position of the transport cart's entry, specifically, when the transport cart enters and presses down on one side of the frame 203, the frame 203 rotates due to the force. This rotation drives the connecting rod 206 via the second rotating shaft 203a, which in turn drives the rotating drum 205 upward, and drives the toothed belt 202b on the corresponding side upward, causing the toothed belt 202b to mesh with the second gear 306 on that side. At this time, the second gear 306 drives the first output bevel gear 304a or the second output bevel gear 304b coaxially mounted therewith to rotate via the rotating rod 305. In other words, if the transport cart presses against one side of the frame 203, causing the left transmission section to activate, then the first output bevel gear 304a performs the power transmission; conversely, if the right transmission section activates, the second output bevel gear 304b assumes the task of power transmission. In short, the system can flexibly and intelligently select the transmission part corresponding to the first output bevel gear 304a or the transmission part corresponding to the second output bevel gear 304b to transmit power according to the actual position and entry direction of the transport vehicle, thereby realizing an efficient power distribution and transmission mechanism.

[0048] Furthermore: when the transport trolley slides forward to the docking point on the previous horizontal track relying on the chain driving force or inertia of the previous horizontal track, its own weight will be applied to one end of the frame 203, causing the frame 203 to rotate like a lever. In this case, one end of the frame 203 is subjected to downward pressure and sinks. According to the lever principle, the other end of the frame 203 will rise accordingly to form an interception surface. When the transport trolley slides to the end of the conveyor belt 202, the raised part of the frame 203 is like a gate, which can offset the remaining kinetic energy of the transport trolley in time and prevent it from rushing out of the docking area due to excessive inertia, thereby ensuring that the transport trolley can stop accurately and smoothly at the predetermined position and complete the effective docking between the tracks. This design not only improves the safety of the system, but also ensures the smoothness and stability of the entire docking process.

[0049] The toothed belt 202b on the connecting track and the chain on the horizontal track are located on the same straight line, and the two correspond to each other. The protrusion at the bottom of the transport trolley ( Figure 3It is just a simple illustration. In practice, the protrusions are arranged closely like racks and cooperate with the chain) and move directly from the chain to the toothed belt 202b. During this process, the frame 203 is always located on the outside of the transport trolley. Therefore, when one end of the frame 203 is pressed down by the protrusion, the raised cross bar at the other end forms an intercepting bar in the space above the end of the toothed belt 202b along the moving direction. It is further necessary to explain that the cross bars at both ends of the frame 203 are set to be trapezoidal or triangular, and their bottom sides are fixed to the two side plates of the frame 203. In this way, when the frame 203 is horizontal, the upper ends of the cross bars at both ends are higher than the "same straight line of the toothed belt 202b on the connecting track and the chain on the horizontal track". However, due to the setting of its inclined surface, the transport trolley can move along its inclined surface, thereby pressing the cross bar downward, realizing and maintaining the lever change of the frame 203. When the front end of the transport trolley box hits the cross bar, the transport trolley is blocked, thereby intercepting and stopping the transport trolley. At the same time, the front end of the transport trolley box is in contact with the cross bar, thereby maintaining the position of the cross bar at this height, and then locking the position of the frame, so that the frame 203 continues to maintain this downward pressure state. This is a fast state for the connection, so that the transport trolley can first press down one end of the frame 203, and in the process of maintaining the other end of the frame 203 tilted up, the front end of the transport trolley hits the tilted end and maintains the tilted state of the frame. Furthermore, since the length of the connecting track is not long and is almost the same as that of the transport trolley, the front end of the transport trolley box fits into the cross bar, and the end of the transport trolley box is still above the cross bar at the other end of the frame 203, thereby pressing it down.

[0050] A groove 201a is provided at the center of the receiving housing 201. A force storage member 301, configured as a spring, is engaged within this groove 201a. The ratchet wheel 302a of the ratchet and tooth member 302 is inserted into the center of the force storage member 301 via a block at the center of the bottom surface. Ratchet teeth 302b are provided on the side of the ratchet wheel 302a. The ratchet teeth 302b are provided on the receiving housing 201 and have a magnet attached to one end. An electromagnet 307 is also provided on the receiving housing 201, located on the side of the ratchet teeth 302b.

[0051] It should be noted that the on / off switching of the electromagnet 307 is used to determine whether the ratchet 302a remains locked with the ratchet teeth 302b. When the electromagnet 307 is de-energized, the ratchet teeth 302b engage with the ratchet 302a under the action of an internal reset spring, preventing the ratchet 302a from freely reversing. At this point, the ratchet teeth 302b are locked with the ratchet 302a. During the movement of the transport trolley, its own inertia drives the toothed belt 202b to rotate, which then passes through the output bevel gear 304, the input bevel gear 303, and the ratchet 302a in sequence, forming a transmission chain. This allows the force storage member 301 to gradually accumulate and store energy during this process, i.e., to store force.

[0052] On the contrary, when the electromagnet 307 is energized, if it is set to the unlocking mode, the ratchet 302b disengages the ratchet 302a. When the force storage member 301 accumulates enough potential energy that needs to be released, the ratchet 302a starts to rotate in the opposite direction driven by the reaction force released by the force storage member 301. The reverse rotating ratchet 302a then drives the input bevel gear 303 and the output bevel gear 304 to work together, and finally converts the stored energy into mechanical power through the toothed belt 202b, prompting the transport trolley to move in the opposite direction from its current position, thereby completing the ejection of the transport trolley from the receiving shell 201.

[0053] In this embodiment, the transport trolley is driven by the chain on the previous horizontal track to move toward the receiving shell 201. Under the action of the chain, the front end of the transport trolley first contacts the horizontal frame 203. The outer side of the frame 203 is set to a trapezoidal shape, thereby pressing down this end of the frame 203. Since the frame 203 is set in the form of a lever, the other end of the frame 203 is tilted. The rotation of the frame 203 drives the fixedly connected second rotating shaft 203a to rotate. The rotation of the second rotating shaft 203a drives the connecting rod 206 and the rotating drum 205 to deflect. The displacement of the sleeve lifts up the lower side of the toothed belt 202b of the conveyor belt 202, so that the toothed belt 202b and the rotating drum 205 are aligned. The second gear 306 is engaged, so when the transport trolley drives the toothed belt 202b to rotate, the toothed belt 202b drives the second gear 306 to rotate, and the second gear 306 drives the output bevel gear 304 fixedly connected to it to rotate through the rotating rod 305, and the output bevel gear 304 drives the input bevel gear 303 to rotate, and the input bevel gear 303 drives the ratchet 302a to rotate, and the ratchet 302a drives the spring of the force storage piece 301 to tighten and store force, until the transport trolley is completely moved to the receiving shell 201 under the action of the chain and inertia and is blocked by the raised end of the frame 203, and stops moving, and also stops storing force.

[0054] When the receiving shell 201 corresponds to the next horizontal track under the action of the lifting member 102 and the rotating member 103, the electromagnet 307 arranged on the side of the ratchet 302b is energized to generate magnetic force, and is magnetically attracted to the magnetic block on the ratchet 302b, thereby removing the ratchet 302b from the ratchet wheel 302a. In this way, the mainspring is no longer locked by the ratchet and ratchet member 302, and will drive the ratchet wheel 302a to rotate in the reverse direction. The ratchet wheel 302a drives the input bevel gear 303 to rotate in the reverse direction. The input bevel gear 303 drives the two output bevel gears 304 to rotate. The output bevel gear 304 drives the second The gear 306 rotates, and the second gear 306 drives the toothed belt 202b meshing with it to rotate. The rotation of the toothed belt 202b drives the conveyor belt 202 to rotate, thereby transporting the transport cart on the conveyor belt 202 in the opposite direction and transferring it to the next horizontal track. The electromagnet 307 is then turned off, so that the ratchet 302b re-locks the ratchet 302a under the action of the internal reset spring, allowing the released force storage member 301 to re-store force. At the same time, the frame 203 returns to the horizontal position under the action of the internal torsion spring, all in preparation for the next transport cart.

[0055] In summary, the core of this part is to utilize a bidirectional transmission design and energy storage mechanism to achieve precise transfer of the transport trolley between different tracks and efficient power management. When the transport trolley enters from either side of the receiving shell 201, its own gravity acts on the frame 203 and is converted into mechanical power when the toothed belt 202b is lifted through the designed connecting rod 206 and rotating drum 205 mechanism. This ensures that whether entering from the left or right side, the toothed belt 202b on one side will be driven to closely engage with the corresponding second gear 306. Once the engagement is successful, the second gear 306 on the left or right side drives the first output bevel gear 304a or second output bevel gear 304b connected to it through the rotating rod 305 to rotate forward, thereby driving the input bevel gear 303 to rotate. Since the input bevel gear 303 is fixed to the ratchet 302a, the kinetic energy of the transport trolley can be captured and converted into potential energy within the power storage member 301 after being transmitted through the toothed belt 202b and the output bevel gear 304, thus completing the energy storage process.

[0056] When the force storage member 301 needs to release stored energy to transfer the transport trolley from the toothed belt 202b to the next track, the force storage member 301 reverses the input bevel gear 303 and the corresponding output bevel gear 304 through the ratchet 302a. This reversal process causes the meshing toothed belt 202b to reverse, thereby driving the transport trolley in the opposite direction. This ensures that no matter which side the trolley enters from, the clever symmetrical design ensures that the toothed belt 202b reverses and smoothly and efficiently pushes the trolley to the next track from either side. This device combines a double-sided transmission structure with an energy storage and release mechanism to ensure that no matter which side the transport trolley enters from, it can flexibly and efficiently utilize its own kinetic energy to store energy and release energy at the appropriate time, allowing the trolley to smoothly transfer between different tracks.

[0057] The remaining structures are the same as those of Example 1.

[0058] Example 3

[0059] Reference Figure 1 and Figure 4 , which is the third embodiment of the present invention, differs from the second embodiment in that: the lifting member 102 includes a plate 102a mounted on the frame 101, a hydraulic cylinder 102b mounted below the plate 102a, a guide rod 102c mounted within the frame 101, and a moving plate 102d that moves up and down along the guide plate. The output shaft of the hydraulic cylinder 102b is mounted below the moving plate 102d. The rotating member 103 includes a motor 103a mounted below the moving plate 102d. The receiving housing 201 is rotatably mounted above the moving plate 102d, and the moving plate 102d has a through hole in its center. The output shaft of the motor 103a passes through the moving plate 102d and is fixed to the receiving housing 201.

[0060] It should be noted that a receiving shell 201 is rotatably arranged above the moving plate 102d, that is, a plane bearing, ball bearing or other rotatable parts are arranged between the bottom surface of the receiving shell 201 and the upper surface of the moving plate 102d, so that the moving plate 102d directly bears the weight of the receiving shell 201 and the components located on the receiving shell 201, so that the motor 103a arranged at the bottom of the moving plate 102d and fixed to the bottom surface of the receiving shell 201 through the output shaft can easily drive the receiving shell 201 to turn, thereby realizing the steering of the transport trolley located inside the receiving shell 201, and is used to connect and move the transport trolley between horizontal rails in different directions. The setting of the hydraulic cylinder 102b and the moving plate 102d is used to drive the lifting and lowering of the receiving component 200 and the transport trolley to realize the switching of the transport trolley between horizontal rails at different heights.

[0061] In this embodiment, when it is necessary to connect two adjacent horizontal rails of different heights, the hydraulic cylinder 102b is first activated to extend and retract to drive the moving plate 102d to move up and down accordingly along the multiple guide rods 102c. The lifting of the moving plate 102d drives the rotating member 103 and the receiving component 200 installed thereon to also move up and down, thereby lifting the receiving component 200 to the end of the rail where the transport trolley moves and keeps it flush with it, allowing the transport trolley to move onto the receiving component 200 and be locked, and then the output shaft of the hydraulic cylinder 102b is extended to the highest point to lift the receiving component 200. 0 rises to the top of the frame 101, so that the receiving component 200 will not be blocked by the surrounding frames 101 when it rotates, and then the motor 103a is started to drive the receiving shell 201 of the receiving component 200 to rotate on the moving plate 102d through the output shaft, so that the transport trolley can move directly to the next horizontal track, and then the hydraulic cylinder 102b controls the lifting and lowering of the moving plate 102d, and controls the lifting and lowering of the bearing component and the transport trolley, so that the transport trolley is flush with the next horizontal track, and then the bearing component pushes the transport trolley to the next horizontal track for transportation.
