A bare ring groove car

Abstract

This application discloses a bare bead tank cart, belonging to the technical field of tire production auxiliary equipment. It includes a frame with a panel fixedly mounted on the top. By employing a frame, energy-absorbing components, a reset component, and a moving component, this application achieves a buffering effect during collisions. The energy-absorbing component first contacts the obstruction and absorbs the energy through distance contraction, reducing the impact energy on the bare bead tank cart until it stops. Simultaneously, since the bare bead tank cart is initially tilted when manually pushed to the unloading station, its position is manually adjusted to near-horizontal after it stops. Then, the reset component contacts the obstruction and pushes the cart backward, aligning its center with the mechanical gripper. This effectively solves the problem of the bare bead tank cart being difficult to stop after being pushed to the loading station, thus making it easy to stop and prevent impact after being pushed to the loading station.

Description

Technical Field

[0001] This application relates to the field of tire production auxiliary equipment technology, and more specifically, to a bare tire bead tanker. Background Technology

[0002] The transfer process for steel wire rings (such as tire wire rings, industrial steel wire rings, etc.) needs to take into account their material characteristics (metal products, which may have sharp edges and be heavy), storage requirements, and transportation scenarios (intra-factory transfer, off-factory logistics, etc.) to ensure safety, efficiency, and avoidance of damage.

[0003] In related technologies, to address the issue of wire rings not being properly aligned when placed on a transfer cart, causing the robotic arm in the next process to fail to grasp the wire ring due to its tilt, a patent with publication number CN216969770U provides a transfer cart that can adaptively fix wire rings of different specifications. This device uses a swinging component to drive the fixing component to swing back and forth, thus adapting to wire rings of different diameters. By setting multiple swinging components and fixing components, multi-point fixation of the corresponding wire rings is achieved. When a larger diameter wire ring is placed in the transfer cart, the swinging component swings backward to accommodate its larger diameter. This causes the fixing component at the upper end of the swinging component to move backward, while the fixing component at the lower end of the swinging component moves forward (i.e., towards the wire ring). The four fixing points of the V-shaped fixing component achieve a tight clamping effect on the wire ring. If the wire ring diameter is smaller, the movement of the swinging component and fixing component is opposite to that of the larger diameter wire ring.

[0004] While the existing technical solutions described above have solved the problem of automatically fixing and aligning the wire rings on the transfer cart, when transporting the transfer cart to the next workstation for unloading, due to the large weight of the transfer cart and the inconsistency in the speed control of manually pushing the transfer cart, when the operator wants to stop the transfer cart, the transfer cart still tends to move forward due to its own inertia. At this time, it is difficult for the operator to stop the transfer cart in time. If it cannot be stopped in time, the transfer cart will continue to move forward and cause a collision accident.

[0005] In view of this, we propose a bare ring tank car. Utility Model Content

[0013] As an optional solution to the technical solution in this application, the reset assembly includes a pad and a hydraulic cylinder fixedly disposed on the outside of the cover plate for driving the pad to move.

[0014] As an optional solution to the technical solution of this application, the moving component includes two sets of connecting plates, with each set consisting of two connecting plates. Casters are rotatably mounted on the inner side of each connecting plate. One set of connecting plates is fixedly mounted on the bottom of the frame, while the other set of connecting plates is rotatably mounted on the bottom of the frame. A brake assembly is mounted on the outer side of the rotatably mounted connecting plate.

[0015] As an optional solution to the technical solution in this application, the brake assembly includes two brake pads located on both sides of the caster. The brake pads on both sides are driven and clamped to the outside of the caster by external force.

[0019] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0020] (1) This application employs a frame, energy-absorbing components, a reset component, and a moving component. During a collision, the energy-absorbing component first contacts the obstruction and absorbs the energy during the collision through distance contraction, thus achieving a buffering effect and reducing the collision energy received by the bare ring tank car until the bare ring tank car stops. At the same time, since the bare ring tank car will be in a certain tilted state when manually pushed to the unloading station, after the bare ring tank car stops, the position of the bare ring tank car is manually adjusted to make it approach a horizontal state. Then, the reset component contacts the obstruction and pushes the bare ring tank car backward to align its middle part with the mechanical claw. Therefore, it effectively solves the problem that the bare ring tank car is difficult to stop after being pushed to the loading station, thus making it easy to stop the bare ring tank car after being pushed to the loading station to prevent collision.

[0021] (2) This application drives the pad block to move forward by hydraulic cylinder and after it contacts the obstruction, it drives the bare ring tank car to move backward until its middle part is positioned with the mechanical claw. Then, the sliding pin is driven to move upward by hydraulic push rod. When the sliding pin moves upward, it drives the guide rods on both sides to reach a horizontal state through the guide hole. Thus, the brake pads on both sides can be driven by the connecting block to clamp the caster, thereby achieving the clamping and stopping effect of the caster and completing the braking.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-5 This application discloses a bare ring tanker, including a frame 1, an energy-absorbing component 2, a reset component 3, and a moving component 4. A panel 11 is fixedly installed on the top of the frame 1, and a cover plate 12 is symmetrically fixedly installed on the top of the panel 11. A bare ring limiting component is provided between the cover plates 12 on both sides. A handrail 15 is fixedly installed at one end of the frame 1. The energy-absorbing component 2 is fixedly installed on the outside of the panel 11, at the end away from the handrail 15, for absorbing energy during a collision. The reset component 3 is fixedly installed on the outside of the cover plate 12, at the end of the cover plate 12 close to the energy-absorbing component 2, for driving the tanker and the mechanical claw to perform X-axis positioning. The moving component 4 is symmetrically fixedly installed at the bottom of the frame 1 for supporting the movement of the tanker. The bare ring limiting component includes partitions 13 equally spaced between the cover plates 12 on both sides, and grooved wheels are fixedly installed between two adjacent partitions 13 for limiting the outer side of the bare ring.

[0030] The assembly of the bare ring tanker is completed through the connection between the frame 1, panel 11, cover 12, partition 13, fastener 14, and handrail 15. Before transportation, the wire ring is placed between adjacent partitions 13 and clamped and fixed by the fastener 14. After the bare ring tanker is loaded, it is moved to the next unloading station by moving the component 4 and manually operating the handrail 15 to be picked up. When moving to the next unloading station, due to the large weight of the bare ring tanker and the difference in the speed control of manually pushing the bare ring tanker, when the operator wants to stop the bare ring tanker, the bare ring tanker is affected by its own inertia. It continues to move forward until it collides with the wall inside the factory, which is an obstacle in front of the workstation. During the collision, the energy-absorbing component 2 first contacts the obstacle and absorbs the energy of the collision through distance contraction, thus buffering the impact and reducing the collision energy received by the bare ring tank car until it stops. At the same time, since the bare ring tank car will be in a certain tilted state when it is manually pushed to the unloading station, after the bare ring tank car stops, the position of the bare ring tank car is manually adjusted to make it closer to a horizontal state. Then, the reset component 3 contacts the obstacle and pushes the bare ring tank car backward to align its middle part with the mechanical claw.

[0031] Reference Figure 2 , Figure 3 and Figure 4The energy-absorbing component 2 includes a pressure tube A21, which is fixedly installed on the outside of the panel 11. A pressure tube B22 is slidably installed on the outside of the pressure tube A21. A rubber block 23 is fixedly installed at the end of the pressure tube B22. A piston rod 24 is fixedly installed on the inside of the pressure tube B22 and slides through the end of the pressure tube A21. A working piston 25 is fixedly installed at the end of the piston rod 24. A floating piston 26 is installed inside the pressure tube A21 on the side of the working piston 25 away from the rubber block 23. Hydraulic oil is installed between the working piston 25 and the floating piston 26. High-pressure nitrogen is installed inside the pressure tube A21 on the side of the floating piston 26 away from the hydraulic oil. A return spring 27 is installed inside the pressure tube B22 on the outside of the piston rod 24. The return spring 27 is located at the end of the pressure tube A21. The reset component 3 includes a pad 31 and a hydraulic cylinder fixedly installed on the outside of the cover plate 12 for driving the pad 31 to move. The moving component 4 includes two sets of connecting plates. 41. Each pair of connecting plates 41 forms a group. Casters 49 are rotatably mounted on the inner side of each connecting plate 41. One group of connecting plates 41 is fixedly mounted on the bottom of the frame 1, and the other group of connecting plates 41 is rotatably mounted on the bottom of the frame 1. A brake assembly is mounted on the outer side of the rotatably mounted connecting plate 41. The brake assembly includes two brake pads 48, which are located on both sides of the casters 49. The brake pads 48 on both sides are driven by external force and clamped on the outer side of the casters 49. A connecting block 47 is fixedly mounted on the outer side of each brake pad 48. A guide rod 46 is rotatably mounted on the side of the connecting blocks 47 that is far apart from each other. The other end of the guide rod 46 is rotatably mounted on the bottom of the connecting plate 41. A guide rod 44 is fixedly mounted on the outer side of the guide rod 46. The two guide rods 44 are staggered. A guide hole 45 is opened on the side of the guide rods 44 that is close to each other. A sliding pin 43 is slidably mounted inside the guide hole 45. The sliding pin 43 is fixedly connected to the driving end of the hydraulic push rod 42. The hydraulic push rod 42 is fixedly mounted on the top of the connecting plate 41.

[0032] During the process of absorbing collision energy by the energy-absorbing component 2, the rubber block 23 contacts the obstruction and then acts on the pressure pipe B22, causing the pressure pipe B22 to slide towards the other end of the pressure pipe A21, shortening the distance between the pressure pipe A21 and the pressure pipe B22. During this shortening process, kinetic energy is transferred to the working piston 25, causing it to move towards the floating piston 26. The movement of the working piston 25 compresses the hydraulic oil in the pressure pipe A21, bringing it closer to the floating piston 26. At this time, the floating piston 26 is subjected to pressure and slides towards one end of the pressure pipe A21, compressing the gas. The increased resistance to the floating piston 26 provides a reaction force, thus absorbing the collision energy. When the energy is absorbed, the bare ring tank car stops moving, and then the reset spring 27 achieves a reset effect, facilitating the next energy-absorbing operation. Subsequently, the position of the bare ring tank car is manually adjusted to bring it closer to the... In a horizontal position, the hydraulic cylinder drives the pad 31 to move forward and, after contacting the obstruction, drives the bare ring tank car to move backward until its middle part is positioned with the mechanical claw. Then, the hydraulic push rod 42 drives the sliding pin 43 to move upward. When the sliding pin 43 moves upward, it drives the guide rods 44 on both sides to reach a horizontal position through the guide hole 45. Thus, the connecting block 47 drives the brake pads 48 on both sides to clamp the caster 49, achieving the clamping and stopping effect of the caster 49 and completing the braking. When it is necessary to move the bare ring tank car, the hydraulic push rod 42 causes the sliding pin 43 to move downward, driving the guide rods 44 on both sides to rotate outward, thereby releasing the clamping effect of the brake pads 48 on the caster 49 and releasing the brake. During the rotation of the guide rods 44, the guide rods 46 on their outer sides can keep the connecting block 47 moving close to a horizontal position, thereby ensuring the horizontal stability of the brake pads 48 when clamped.

[0033] Reference Figure 5 A fixing plate 16 is fixedly installed on the outside of the frame 1. An oil tank 17 is fixedly installed on the top of the fixing plate 16. A hydraulic pump 18 is fixedly installed on the outside of the oil tank 17. The input end of the hydraulic pump 18 is connected to the inside of the oil tank 17. A reversing valve 19 is fixedly installed on the output end of the hydraulic pump 18. Oil pipes 110 are fixedly installed on both output ends of the reversing valve 19 for conveying hydraulic oil to drive the hydraulic cylinder and the hydraulic push rod 42 respectively.

[0034] During reset and braking, the hydraulic cylinder and hydraulic push rod 42 are connected to the output ends of the oil pipes 110 on both sides through pipes. Then, the hydraulic pump 18 draws hydraulic oil from the oil tank 17 and delivers it to the reversing valve 19. The reversing valve 19 then delivers hydraulic oil to the oil pipes 110 on both sides. The hydraulic oil is then delivered to the hydraulic cylinder and hydraulic push rod 42 through pipes, forming pressure to drive the output ends of the hydraulic cylinder and hydraulic push rod 42. Then, the reversing valve 19 connected to the oil pipe 110 delivers the returned hydraulic oil back to the oil tank 17 through pipes, realizing circulation.

[0035] In summary, the bare wire ring tanker disclosed in this application is assembled through the connection between the frame 1, panel 11, cover 12, partition 13, fastener 14, and handrail 15. Before transportation, the wire ring is placed between adjacent partitions 13 and clamped and fixed by the fastener 14. After the bare wire ring tanker is loaded, it is moved to the next unloading station by moving the component 4 and manually operating the handrail 15 to be picked up. When moving to the next unloading station, due to the large weight of the bare wire ring tanker and the difference in speed control when manually pushing it, the bare wire ring tanker continues to move forward due to its own inertia when the manual operator tries to stop it, until it hits the obstruction in front of the station. When the wall collides with the tanker truck, the energy-absorbing component 2 first contacts the obstruction and absorbs the energy of the collision through distance contraction, thus buffering the impact and reducing the impact energy received by the bare ring tanker until it stops. Simultaneously, since the bare ring tanker is initially tilted when manually pushed to the unloading station, its position is manually adjusted to near-horizontal after it stops. Then, the reset component 3 contacts the obstruction and pushes the bare ring tanker backward, aligning its center with the mechanical gripper. During the energy absorption process of the energy-absorbing component 2, the rubber block 23 contacts the obstruction and then acts on the pressure pipe B22, causing it to slide towards the other end of the pressure pipe A21, shortening the pressure pipe A21. The distance between pressure pipe A21 and pressure pipe B22 is shortened. Kinetic energy is transferred to working piston 25, causing it to move towards floating piston 26. The movement of working piston 25 compresses the hydraulic oil in pressure pipe A21, bringing it closer to floating piston 26. At this time, floating piston 26 is pressured and slides towards one end of pressure pipe A21, compressing the gas. The increased resistance to floating piston 26 generates a reaction force, thus absorbing the collision energy. Once the energy is absorbed, the bare ring tank car stops moving, and the reset spring 27 achieves a reset effect, facilitating the next energy absorption operation. Then, the position of the bare ring tank car is manually adjusted to approach a horizontal state, and the hydraulic cylinder drives the pad block 31 to move forward. After contacting the obstruction, the bare ring tank car is driven to move backward until its middle part is positioned with the mechanical gripper. Then, the hydraulic push rod 42 drives the sliding pin 43 to move upward. When the sliding pin 43 moves upward, it drives the guide rods 44 on both sides to reach a horizontal state through the guide hole 45. This allows the brake pads 48 on both sides to clamp the caster 49 through the connecting block 47, achieving a clamping and stopping effect on the caster 49, thus completing the braking. When it is necessary to move the bare ring tank car, the hydraulic push rod 42 causes the sliding pin 43 to move downward, driving the guide rods 44 on both sides to rotate outward, thereby releasing the clamping effect of the brake pads 48 on the caster 49 and releasing the brake. During the rotation of the guide rods 44, the connecting block 47 can be kept close to horizontal movement through the guide rod 46 on its outer side.This ensures the horizontal stability of the brake pads 48 during clamping. During reset and braking, the hydraulic cylinder and hydraulic push rod 42 are connected to the output ends of the oil pipes 110 on both sides via pipelines. The hydraulic pump 18 draws hydraulic oil from the oil tank 17 and supplies it to the reversing valve 19. The reversing valve 19 then supplies hydraulic oil to the oil pipes 110 on both sides. The hydraulic oil is then supplied to the hydraulic cylinder and hydraulic push rod 42 through pipelines, creating pressure to drive the output ends of the hydraulic cylinder and hydraulic push rod 42. Finally, the reversing valve 19 connected to the oil pipe 110 sends the returning hydraulic oil back to the oil tank 17 through pipelines, achieving circulation.
