Description

Technical Field

[0001] This invention relates to the field of transfer trolley technology, specifically to a self-stabilizing transfer trolley for current collectors. Background Technology

[0002] In the production of current collectors, since the products produced are rolls of metal film paper or composite film paper, their end faces are easily damaged. During the production and slitting process, transfer vehicles are needed to transport and lift the raw materials onto the machine and the finished products off the machine.

[0003] Existing technology uses hydraulic trolleys for transfer, which can only perform transportation and lifting functions. During transportation, rough protective gear is required to prevent the roll from rolling. When the roll needs to be reversed or weighed, manual lifting is required for reversal and weighing. Furthermore, it cannot effectively counteract the lateral tilt of the trolley when turning. When mass production is carried out on an assembly line, the weighing, reversing, and transportation of the roll will waste a lot of manpower and time. Moreover, when the roll is too heavy, there will be significant safety hazards, causing damage to the roll or even personal injury.

[0004] Therefore, there is an urgent need to develop a transfer trolley that can automatically change direction and automatically adjust tilt to meet the requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a self-stabilizing transfer trolley for current collectors to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A self-stabilizing transfer trolley for collecting fluid includes a frame, a transfer platform, an electro-hydraulic actuator, a moving system, a detection device, and a power supply. The transfer platform is fixedly connected to the electro-hydraulic actuator, which is located below the transfer platform. The electro-hydraulic actuator is fixedly connected to the frame. The moving system is fixedly connected to the frame. The detection device is fixedly connected to the frame and electrically connected to the power supply. The detection device is electrically connected to the moving system. The power supply is fixedly connected to the frame. The transfer platform includes a U-shaped fixing groove, a steering device, and a weighing device. The U-shaped fixing groove is fixedly connected to the weighing device, which is located below the U-shaped fixing groove. The steering device is fixed below the weighing device and is fixedly connected to the electro-hydraulic actuator.

[0007] The frame serves as the mounting base for all mechanisms. The transfer platform holds the roll material to be transferred. The electro-hydraulic actuator moves the transfer platform up and down, transporting the roll material to a suitable height. The moving system moves the trolley. The detection device determines the tilt of the trolley when turning and transmits a signal to the moving system for adjustment. The power supply provides energy to the trolley. The surface of the U-shaped fixing groove is covered with a soft protective foam pad to protect the roll material from impacts and damage. The cross-section of the U-shaped fixing groove fits the roll material to prevent shaking during transport. The weighing device is located below the U-shaped fixing groove, allowing direct weighing of the roll material after it is placed inside. The steering device rotates the U-shaped fixing groove, allowing for direct reversal of the roll material's direction if it is misaligned. This reduces the frequency of manual labor and improves the convenience and safety of transportation.

[0008] Furthermore, the mobility system includes wheels, shock absorbers, and a fixing device. The wheels are rotatably connected to the fixing device, the fixing device is securely connected to the frame, and the shock absorbers are securely connected to the frame.

[0009] The wheels are designed with wheel-side motors, allowing all four wheels to rotate independently, which improves the trolley's flexibility. The shock absorption device can buffer the shaking during transportation and ensure stable transportation. The fixing device secures the wheels and shock absorption device to the frame, improving the stability of the mobile system.

[0010] Furthermore, the detection device includes a housing, a resistance rod, a conductive ring, a sliding block, and a first spring. The housing is fastened to the vehicle frame, and a sliding groove is provided inside the housing. The resistance rod is fastened to the housing, the conductive ring is slidably connected to the resistance rod, the conductive ring is fastened to the sliding block, the sliding groove is fastened to the housing, the sliding block is slidably connected to the sliding groove, the first spring is located in the sliding groove, the first spring is fastened to the sliding block, and the resistance rod is electrically connected to a power source.

[0011] The outer casing secures the detection device to the frame. Made of insulating material, the casing prevents leakage. The resistance rod is connected to the power supply via wires. A sliding block slides within a sliding groove, causing a conductive ring fixed to the sliding block to slide along the resistance rod. The weight of the sliding block is greater than that of the conductive ring, making the ring easier to move. A first spring resets the moved sliding block. When the vehicle turns right, the sliding block experiences a centrifugal force to the left, causing it to slide left along the sliding groove, which in turn causes the conductive ring to slide left. This shortens the distance the current travels through the resistance rod, reducing the resistance and increasing the outflowing current.

[0012] Furthermore, the detection device also includes a first electrode plate and a second electrode plate, which are fastened to the outer shell and electrically connected to the shock absorption device respectively.

[0013] During testing: The conductive ring abuts against the first electrode plate.

[0014] The detection device is used to detect the degree of tilt of the car when it turns. The greater the degree of tilt when turning, the greater the centrifugal force on the car. The first and second electrode plates will come into contact with the conductive ring during detection, thereby guiding the current to the damping device. The damping device can be adjusted according to the magnitude of the inflow current, thereby balancing the tilt of the car and realizing the self-stabilization of the device.

[0015] Furthermore, the conductive ring includes a ring body and balls. The ring body is fastened to the sliding block, and several balls are arranged inside the ring body. The balls are in rolling connection with the resistance rod.

[0016] The sliding block is also made of insulating material to prevent leakage. The conductive ring is slidably connected to the resistance rod through a ball bearing, which reduces the contact area between the ring and the resistance rod, thereby reducing the friction between them and making the conductive ring slide more smoothly on the resistance rod, thus improving the accuracy of the detection.

[0017] Furthermore, the shock absorption device includes a protective shell, a first moving rod, a second moving rod, a second spring, and a magnetic assembly. The protective shell has a sliding cavity. The first and second moving rods are slidably connected to the sliding cavity, respectively. The second spring is sleeved on the corresponding first and second moving rods. The magnetic assembly is fastened to the first and second moving rods, respectively. The magnetic assembly on the same side of the first and second electrode plates is electrically connected. The magnetic assembly on the same side of the second electrode plate is electrically connected to the magnetic assembly on the same side of the first electrode plate. The second spring is fastened to the protective shell. The first moving rod is fastened to the vehicle frame. The second moving rod is fastened to the fixing device.

[0018] The protective shell provides protection for the shock absorption device. When the trolley encounters uneven surfaces during movement, it will vibrate. The second spring will extend and retract due to the vibration, thereby driving the first and second moving rods to move up and down along the sliding cavity, which in turn drives the magnetic component to move. By converting vibration into movement, the road vibration is filtered, improving the smoothness of the trolley's movement and preventing the roll material from shaking.

[0019] Furthermore, the shock absorption device also includes a hydraulic system. The sliding chamber contains hydraulic oil. The hydraulic system is securely connected to the frame. The hydraulic system includes an oil tank, a hydraulic pump, an inlet pipe, a return pipe, and a solenoid directional valve. The oil tank is securely connected to the frame, the hydraulic pump is securely connected to the frame, the inlet of the hydraulic pump is connected to the oil tank, the outlet of the hydraulic pump is connected to the inlet of the inlet pipe, the solenoid directional valve is securely connected to the protective shell, the outlet of the inlet pipe is connected to the solenoid directional valve, the return pipe is connected to the solenoid directional valve, and the outlet of the return pipe is connected to the oil tank.

[0020] When the roll material is placed on the trolley, its weight exerts downward pressure on the trolley, compressing the second spring and shortening its stroke, which affects the shock absorption effect. Based on the weight of the roll material measured by the weighing device, the hydraulic pump starts to draw hydraulic oil from the oil tank and introduce it into the oil inlet pipe. The oil then enters the sliding chamber through the solenoid directional valve, increasing the pressure of the hydraulic oil in the sliding chamber. This pushes the magnetic component to move, which in turn moves the first and second moving rods, keeping the second spring, which is fitted on the first and second moving rods, at a suitable stroke. If the roll material is relatively light, the solenoid directional valve is connected to the return pipe, allowing excess hydraulic oil to be returned to the oil tank for reuse.

[0021] Furthermore, the magnetic component includes a first electromagnet and a second electromagnet, which are located inside the sliding cavity. The first electromagnet and the second electromagnet are slidably connected to the sliding cavity, and are electrically connected to the detection device. The magnetic poles of the first electromagnet and the second electromagnet are opposite.

[0022] Because the first and second electromagnets have opposite magnetic poles, a repulsive force is generated between them after energization, lifting the cart to counteract its tilt when turning. The first electrode plate is connected to the magnetic component on the right side of the cart via a wire, and the second electrode plate is connected to the magnetic component on the left side of the cart via a wire. For example, when the cart turns right, the right end of the cart moves down, and the sliding block experiences a centrifugal force to the left, causing it to slide to the left along the sliding groove. This, in turn, causes the conductive ring to slide to the left and connect with the first electrode plate, thus guiding the current to the magnetic component on the right. The greater the offset, the greater the centrifugal force on the cart, the farther the conductive ring moves to the left, the shorter the distance the current flows through the resistance rod, the greater the current transmitted to the magnetic component, and the greater the repulsive force generated by the first and second electromagnets after energization, lifting the cart and compensating for the cart's tilt when turning. This process can be automatically adjusted.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: Through the above-mentioned technology, when transferring the roll material, the roll material is placed in a U-shaped fixing groove. The surface of the U-shaped fixing groove is covered with a soft protective foam pad to protect the roll material and prevent it from being bumped or damaged. Furthermore, the cross-section of the U-shaped fixing groove fits the roll material, preventing it from shaking during transport. The weight of the material can be directly recorded using a weighing device. During the loading of the roll material onto the machine, an electro-hydraulic actuator lifts the roll material to the required height. If the roll material is in the wrong orientation, the turning device can be used to directly reverse its direction. This reduces the frequency of manual labor and improves the convenience and safety of transportation. Based on the weight of the roll material measured by the weighing device, the hydraulic pump and electromagnetic reversing valve are automatically adjusted to keep the second spring at a suitable stroke, ensuring the shock absorption effect. By utilizing the magnitude of the centrifugal force during the trolley's turning process, the conductive ring is driven to slide on the resistance rod, changing the resistance value to automatically adjust the current transmitted to the magnetic component, realizing the automatic adjustment of the repulsive force between the first and second electromagnets, automatically compensating for the trolley's tilt when turning, keeping the trolley self-stabilized, and ensuring the safety of the transfer process.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The present invention provides the following technical solution:

[0036] like Figure 1 As shown, a self-stabilizing transfer trolley for collecting fluid includes a frame 1, a transfer platform 2, an electro-hydraulic actuator 3, a moving system 4, a detection device 5, and a power supply 6. The transfer platform 2 is fixedly connected to the electro-hydraulic actuator 3, which is located below the transfer platform 2. The electro-hydraulic actuator 3 is fixedly connected to the frame 1. The moving system 4 is fixedly connected to the frame 1. The detection device 5 is fixedly connected to the frame 1 and electrically connected to the power supply 6. The detection device 5 is electrically connected to the moving system 4. The power supply 6 is fixedly connected to the frame 1. The transfer platform 2 includes a U-shaped fixing groove 21, a steering device 22, and a weighing device 23. The U-shaped fixing groove 21 is fixedly connected to the weighing device 23, which is located below the U-shaped fixing groove 21. The steering device 22 is fixed below the weighing device 23 and is fixedly connected to the electro-hydraulic actuator 3.

[0037] The frame 1 serves as the mounting base for all mechanisms. The transfer platform 2 is used to place the roll material to be transferred. The electro-hydraulic actuator 3 can drive the transfer platform 2 to move up and down, thereby transporting the roll material to a suitable height. The moving system 4 can drive the trolley to move. The detection device 5 is used to determine the tilt degree of the trolley when turning and transmits a signal to the moving system 4 for adjustment. The power supply 6 provides energy to the trolley. The surface of the U-shaped fixing groove 21 is covered with a soft protective foam pad to protect the roll material and prevent it from being bumped and damaged. In addition, the cross section of the U-shaped fixing groove 21 fits the roll material to prevent it from shaking during transportation. The weighing device 23 is set below the U-shaped fixing groove 21. When the roll material is placed in the U-shaped fixing groove 21, its weight can be directly weighed. The steering device 22 can drive the U-shaped fixing groove 21 to rotate. Therefore, when the roll material is in the wrong direction, the direction of the roll material can be directly reversed using the steering device 22, reducing the frequency of manual labor and improving the convenience and safety of transportation.

[0038] like Figure 2 , Figure 5 As shown, the mobile system 4 includes a wheel 41, a shock absorber 42, and a fixing device 43. The wheel 41 is rotatably connected to the fixing device 43, the fixing device 43 is fastened to the frame 1, and the shock absorber 42 is fastened to the frame 1.

[0039] The wheels 41 adopt a wheel-side motor design, so that all four wheels 41 can rotate independently, which improves the flexibility of the trolley. The shock absorption device 42 can buffer the shaking during the transfer process and ensure the stability of the transfer. The fixing device 43 fixes the wheels 41 and the shock absorption device 42 to the frame 1, which improves the stability of the moving system 4.

[0040] like Figure 3 As shown, the detection device 5 includes a housing 51, a resistance rod 52, a conductive ring 53, a sliding block 55, and a first spring 56. The housing 51 is fixedly connected to the frame 1. A sliding groove 511 is provided inside the housing 51. The resistance rod 52 is fixedly connected to the housing 51. The conductive ring 53 is slidably connected to the resistance rod 52. The conductive ring 53 is fixedly connected to the sliding block 55. The sliding groove 511 is fixedly connected to the housing 51. The sliding block 55 is slidably connected to the sliding groove 511. The first spring 56 is located inside the sliding groove 511. The first spring 56 is fixedly connected to the sliding block 55. The resistance rod 52 is electrically connected to the power supply 6.

[0041] The outer casing 51 fixes the detection device 5 to the frame 1. The outer casing 51 is made of insulating material to prevent leakage. The resistance rod 52 is connected to the power supply 6 through wires. The sliding block 55 can slide in the sliding groove 511, thereby driving the conductive ring 53 fixed to the sliding block 55 to slide on the resistance rod 52. The weight of the sliding block 55 is greater than that of the conductive ring 53, making the conductive ring 53 easier to move. The first spring 56 can reset the moved sliding block 55. When the car turns right, the sliding block 55 will be subjected to a centrifugal force to the left, thereby sliding to the left along the sliding groove 511, and thus driving the conductive ring 53 to slide to the left. In this way, the distance of the current through the resistance rod 52 will be shortened, the resistance value will be reduced, and the outflowing current will be increased.

[0042] like Figure 3 As shown, the detection device 5 also includes a first electrode plate 57 and a second electrode plate 58. The first electrode plate 57 and the second electrode plate 58 are fastened to the outer shell 51, and the first electrode plate 57 and the second electrode plate 58 are electrically connected to the shock absorption device 42 respectively.

[0043] During testing: the conductive ring 53 abuts against the first electrode plate 57.

[0044] The detection device 5 is used to detect the degree of tilt of the car when it turns. The greater the degree of tilt when turning, the greater the centrifugal force on the car. The first electrode plate 57 and the second electrode plate 58 will come into contact with the conductive ring 53 during detection, thereby guiding the current to the shock absorption device 42. The shock absorption device 42 can be adjusted according to the magnitude of the inflow current, thereby balancing the tilt of the car and realizing the self-stabilization of the device.

[0045] like Figure 4 As shown, the conductive ring 53 includes a ring body 531 and ball bearings 532. The ring body 531 is fastened to the sliding block 55. Several ball bearings 532 are arranged inside the ring body 531, and the ball bearings 532 are tumbling connected to the resistance rod 52.

[0046] The sliding block 55 is also made of insulating material to avoid leakage. The conductive ring 53 is slidably connected to the resistance rod 52 through the ball 532, which can reduce the contact area between the ring 531 and the resistance rod 52, thereby reducing the friction between the two and making the sliding of the conductive ring 53 on the resistance rod 52 smoother and improving the accuracy of detection.

[0047] like Figure 5 , Figure 6As shown, the shock absorption device 42 includes a protective shell 421, a first moving rod 422, a second moving rod 423, a second spring 424, and a magnetic component 425. The protective shell 421 has a sliding cavity 4211. The first moving rod 422 and the second moving rod 423 are slidably connected to the sliding cavity 4211, respectively. The second spring 424 is sleeved on the corresponding first moving rod 422 and the second moving rod 423. The magnetic component 425 is fastened to the first moving rod 422 and the second moving rod 423, respectively. The magnetic component 425 on the same side of the first electrode plate 57 and the second electrode plate 58 is electrically connected. The magnetic component 425 on the same side of the second electrode plate 58 and the first electrode plate 57 is electrically connected. The second spring 424 is fastened to the protective shell 421. The first moving rod 422 is fastened to the frame 1. The second moving rod 423 is fastened to the fixing device 43.

[0048] The protective shell 421 provides protection for the shock absorption device 42. When the trolley encounters unevenness during movement, it will vibrate. The second spring 424 will extend and retract due to the vibration, thereby driving the first moving rod 422 and the second moving rod 423 to move up and down along the sliding cavity 4211, which in turn drives the magnetic component 425 to move. By converting vibration into movement, the road vibration is filtered, the smoothness of the trolley movement is improved, and the roll material is prevented from shaking.

[0049] like Figure 6 As shown, the shock absorber 42 also includes a hydraulic system 426. The sliding chamber 4211 contains hydraulic oil. The hydraulic system 426 is fixedly connected to the frame 1. The hydraulic system 426 includes an oil tank 4261, a hydraulic pump 4262, an oil inlet pipe 4263, a return pipe 4264, and a solenoid directional valve 4265. The oil tank 4261 is fixedly connected to the frame 1, the hydraulic pump 4262 is fixedly connected to the frame 1, the oil inlet of the hydraulic pump 4262 is connected to the oil tank 4261, the oil outlet of the hydraulic pump 4262 is connected to the inlet of the oil inlet pipe 4263, the solenoid directional valve 4265 is fixedly connected to the protective shell 421, the outlet of the oil inlet pipe 4263 is connected to the solenoid directional valve 4265, the return pipe 4264 is connected to the solenoid directional valve 4265, and the outlet of the return pipe 4264 is connected to the oil tank 4261.

[0050] When the roll material is placed on the trolley, the weight of the roll material exerts a downward pressure on the trolley, thereby compressing the second spring 424 and shortening its stroke, which affects the shock absorption effect. Based on the weight of the roll material measured by the weighing device 23, the hydraulic pump 4262 starts to draw hydraulic oil from the oil tank 4261 and introduce it into the oil inlet pipe 4263. The oil then enters the sliding chamber 4211 through the solenoid reversing valve 4265, thereby increasing the pressure of the hydraulic oil in the sliding chamber 4211. This pushes the magnetic component 425 to move, which in turn drives the first moving rod 422 and the second moving rod 423 to move, so that the second spring 424, which is sleeved on the first moving rod 422 and the second moving rod 423, is kept at a suitable stroke. If the weight of the roll material is light, the solenoid reversing valve 4265 is connected to the return pipe 4264 to return excess hydraulic oil to the oil tank 4261 for reuse.

[0051] like Figure 6 , Figure 7 , Figure 8 As shown, the magnetic component 425 includes a first electromagnet 4251 and a second electromagnet 4252. The first electromagnet 4251 and the second electromagnet 4252 are located in the sliding cavity 4211. The first electromagnet 4251 and the second electromagnet 4252 are slidably connected to the sliding cavity 4211, and the first electromagnet 4251 and the second electromagnet 4252 are electrically connected to the detection device 5. The magnetic poles of the first electromagnet 4251 and the second electromagnet 4252 are opposite.

[0052] Because the first electromagnet 4251 and the second electromagnet 4252 have opposite magnetic poles, a repulsive force is generated between them after energization, lifting the trolley to counteract its tilt when turning. The first electrode plate 57 is connected to the magnetic component 425 on the right side of the trolley via a wire, and the second electrode plate 58 is connected to the magnetic component 425 on the left side of the trolley via a wire. For example, when the trolley turns right, the right end of the trolley moves down, and the sliding block 55 experiences a centrifugal force to the left, thus moving along the sliding groove 5. 11 slides to the left, which in turn drives the conductive ring 53 to slide to the left and connects with the first electrode plate 57, thereby guiding the current to the magnetic component 425 on the right. The greater the offset, the greater the centrifugal force on the car, the farther the conductive ring 53 moves to the left, the shorter the distance the current flows through the resistor rod 53, the greater the current transmitted to the magnetic component 425, and the greater the repulsive force generated after the first electromagnet 4251 and the second electromagnet 4252 are energized, which lifts the car up, realizes the compensation for the car's tilt when turning, and can be automatically adjusted.

[0053] The working principle of this invention is as follows: First, the roll material to be transferred is placed on the U-shaped fixing groove 21. The weighing device 23 can directly record the weight of the roll material and transmit the weight signal to the hydraulic system 426. Through the cooperation of the hydraulic pump 4262 and the solenoid reversing valve 4265, the shock absorption device 42 is maintained in the optimal state. The wheels 41 are started, driving the trolley to move to the designated position. The electro-hydraulic push rod 3 is started, driving the transfer platform 2 to move up and down, lifting the roll material placed in the U-shaped fixing groove 21 to the height required by the machine. If the roll material is in the wrong direction, the steering device 22 rotates to adjust the direction of the roll material. The detection device 5 uses the centrifugal force when the trolley turns to drive the sliding block 55 to slide, thereby driving the conductive ring 53 to slide on the resistance rod 52, thus changing the flow. The magnitude of the output current is adjusted by connecting the first electrode plate 57 and the second electrode plate 58 to the magnetic component 425, thereby adjusting the repulsive force between the first electromagnet 4251 and the second electromagnet 4252 to achieve automatic compensation for the trolley's tilt when turning. For example, when the trolley turns right, the right end of the trolley will tilt, and the sliding block 55 will be subjected to a centrifugal force to the left, thus sliding to the left along the sliding groove 511, which in turn drives the conductive ring 53 to slide to the left and connect with the first electrode plate 57, thereby guiding the current to the magnetic component 425 on the right. The greater the offset, the greater the centrifugal force on the trolley, the farther the conductive ring 53 moves to the left, the shorter the distance the current flows through the resistor rod 53, and the greater the current transmitted to the magnetic component 425.
