Description

Technical Field

[0001] This invention relates to the field of tire manufacturing auxiliary equipment technology, specifically to a rotatable, liftable, and movable wire ring storage trolley with a groove. Background Technology

[0002] In tire manufacturing, the steel bead is one of the core components of the bead structure. Its surface needs to be covered with a rubber layer (steel bead rubber) and triangular rubber to ensure adhesion strength with other parts of the tire. In the current production process, freshly produced steel beads are manually hung onto a trolley and transported to the next process. However, the highly viscous rubber layer / triangular rubber makes adjacent steel beads very easy to stick together. When operators forcibly separate the stuck steel beads, the rubber material on the surface of one steel bead often adheres to the other, causing the latter to have a partial loss of rubber layer and exposed steel wires. This not only affects the structural strength of the tire after molding but may also cause safety hazards due to steel wires puncturing the tire. In addition, deformation of the triangular rubber can also damage its bonding precision with the steel bead, further reducing product quality.

[0003] To address the aforementioned issues, existing solutions typically involve installing multiple horizontal placement rods on a trolley and creating small fixing grooves on these rods to individually place the wire rings, one in each groove, to avoid direct contact. However, these solutions still generally suffer from the following problems: Inconvenient to pick up and put down: The placement pole is usually a long straight pole, and personnel need to place or pick up the wire rings one by one from one end of the pole. Especially when the pole is long, the operation at the end is extremely difficult. For example, the innermost wire ring requires leaning out or bending over to operate, which is inefficient and labor-intensive. Poor placement stability: The wire rings are suspended by only one side of the groove or placed on the fixed rod, lacking lateral or longitudinal constraints. When the trolley is transported to the vulcanization workshop or when there is slight vibration, the wire rings are prone to shaking in the groove or even falling out of the groove. This may cause accidental collision and adhesion between the wire rings, or the shaking may cause wear of the rubber layer / triangular rubber.

[0004] This solution uses three racks with grooved belts to facilitate the placement and removal of the wire rings. At the same time, the three racks are arranged in a triangular pattern, which creates a three-point positioning for the wire rings, making them more stable. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a rotatable, liftable, and movable wire ring storage trolley with a groove. By using a design of "three triangularly arranged grooved belt placement racks" combined with the three-point positioning principle, the present invention solves the problems of inconvenience in picking up and placing wire rings and poor stability of existing wire ring storage trolleys.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A rotatable, liftable, and movable wire ring storage trolley includes a trolley assembly and a placement assembly mounted on top of the trolley assembly. Its core improvement lies in the following: the placement assembly includes a vertically arranged column, with multiple circumferentially arrayed and non-interfering placement mechanisms installed on the side wall of the column; the placement mechanism includes three horizontally arranged placement frames, arranged in a triangular pattern. Each placement frame has rotatable pulleys installed inside its first and last ends. Two pulleys within the same placement frame are driven by a belt. Each belt has several evenly spaced grooves on its outer surface away from the pulleys, allowing the wire rings to be placed.

[0007] By adopting the above scheme, the steel wire rings of the three placement racks can be driven by pulleys, making it easy to adjust the position of the steel wire rings. All steel wire rings can be picked up and put down only at the outer end of the placement rack, which is more convenient. The triangular arrangement of the three placement racks forms a stable spatial layout. When each steel wire ring is placed, it is constrained by the grooves of the three conveyor belts, forming a three-point positioning of the steel wire ring. Compared with the traditional single-bar groove suspension method, it significantly reduces the lateral and longitudinal sway of the steel wire ring, avoids accidental detachment or collision during the transfer process, and makes it more stable.

[0008] In a preferred embodiment of a rotatable, liftable, and grooved steel wire ring storage trolley, the three storage racks consist of two fixed racks and one sliding rack. The two fixed racks are located above the column and on the same horizontal plane, while the sliding rack is located below the column and between the two fixed racks. This layered layout can accommodate steel wire rings of different diameters. Furthermore, based on mechanical principles, three-point positioning (such as an isosceles triangle) is the most stable planar constraint method. The constraint forces exerted on the steel wire rings by the grooves in three directions can balance disturbance forces in any direction.

[0009] In a preferred embodiment of a rotatable, liftable, and movable wire ring storage trolley, a rocker arm is provided between two fixed placement frames, coaxially connecting the outermost pulley inside each frame. The belt of the fixed placement frame can be directly rotated via the rocker arm to adjust its position without contacting the wire ring, thus improving operational safety and convenience.

[0010] In a preferred embodiment of a rotatable, height-adjustable, and movable wire ring storage trolley, a vertically connected slide rod is installed at the inner end of the sliding storage rack, surrounding the column. A lifting slide seat capable of sliding up and down is mounted on the slide rod, and the entire sliding storage rack is mounted on the lifting slide seat. The vertical height of the sliding storage rack can be adjusted by the lifting slide seat to accommodate the storage needs of wire rings of different specifications, enhancing its versatility.

[0011] In a preferred embodiment of a rotatable, height-adjustable wire ring storage trolley with movable grooves, a horizontally arranged positioning pin runs through the side of the lifting slide, and multiple positioning holes evenly distributed along its axial direction are provided on the slide rod to cooperate with the positioning pin. After the positioning pin is inserted into the positioning hole, it ensures that the sliding placement frame is stably fixed after being adjusted to the target height, preventing the sliding frame from accidentally sliding down when the trolley moves, and ensuring the reliability of wire ring storage.

[0012] In a preferred embodiment of a rotatable, liftable, and movable wire ring storage trolley with a movable groove, a horizontally arranged buffer slide is connected to the inner end of the sliding placement frame. The buffer slide is slidably mounted on a spring column vertically connected above a lifting slide. A buffer spring is fitted onto the spring column, capable of pushing the sliding slide downwards. The buffer spring provides a downward preload, ensuring the wire rings on the sliding placement frame always conform to the belt groove, preventing them from shaking and coming off, while also absorbing the impact force during trolley movement and improving stability.

[0013] As a preferred embodiment of a rotatable, height-adjustable, and movable wire ring storage trolley, a motor is coaxially connected to the bottom of the column, allowing the entire column to rotate horizontally under the motor's drive. The motor's rotation of the column synchronously rotates all the placement mechanisms, facilitating the operator to pick up and place the wire rings from any angle without having to walk around the trolley, thus improving efficiency.

[0014] As a preferred embodiment of a rotatable, height-adjustable, and movable wire ring storage trolley, the trolley assembly includes a frame body, four sets of swivel casters connected to the bottom of the frame body, a handlebar connected to one end of the frame body, and a horizontally arranged workbench mounted on top of the frame body. The swivel casters enable flexible transport of the trolley, while the handlebar and workbench provide convenient movement and auxiliary operating conditions for the operator.

[0015] In a preferred embodiment of a rotatable, height-adjustable wire ring storage trolley with movable grooves, a lifting mechanism capable of driving the workbench to move up and down is installed between the trolley frame and the workbench. The lifting mechanism includes a stand, with a driving sprocket and a driven sprocket located on the same side and capable of rotation, respectively, mounted on the bottom and top of the stand. The driving sprocket and the driven sprocket are driven by a chain drive. A screw mounted on a screw seat is coaxially connected to the driving sprocket, with one end of the screw connected to the lifting frame. A crank handle is coaxially connected to the driven sprocket on the screw seat. The operator can adjust the height of the workbench according to their own height or operational needs, such as raising the workbench to a suitable position using the lifting mechanism, reducing bending over or tiptoeing during operation and improving work comfort.

[0016] As a preferred embodiment of a rotatable, liftable, and movable wire ring storage trolley, the lifting frame comprises two sets of equal-length, cross-arranged support arms. The two sets of support arms are vertically arranged and movably connected by a horizontally arranged connecting rod. The bottom of one set of support arms is supported above the trolley frame via pulleys, while the top of the other set of support arms is supported below the worktable via pulleys. The lifting mechanism converts the rotational motion of the crank handle into the linear motion of the screw through chain-sprocket transmission, thereby driving the cross-support arms to extend or retract, thus precisely controlling the lifting height of the worktable. The cross-support arm structure provides stable support, ensuring the stability of the worktable during lifting.

[0017] The beneficial effects of this invention are: 1. Convenient and efficient loading and unloading: The steel wire rings of the three placement racks can be driven by pulleys, making it easy to adjust the position of the steel wire rings. All steel wire rings can be picked up and placed at the outer end of the placement rack, making it more convenient. With the column rotation function, the operator can pick up and place steel wire rings from any angle without walking around the trolley. 2. Strong placement stability: The three triangularly arranged placement frames form a stable spatial layout. Each wire ring is constrained by the grooves of the three conveyor belts when placed, forming a three-point positioning of the wire ring. Compared with the traditional single-bar groove suspension method, this significantly reduces the lateral and longitudinal swaying of the wire ring, avoiding accidental detachment or collision during transportation, making it more stable. The buffer spring provides downward preload, ensuring that the wire ring on the sliding placement frame always fits against the belt groove, preventing swaying and detachment, while absorbing the impact force when the trolley moves, improving stability. 3. Adaptability and versatility: The vertical height of the sliding rack can be adjusted by lifting the slide block to accommodate the storage needs of steel wire rings of different specifications, thus enhancing its versatility.

Detailed Implementation

[0021] 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.

[0022] like Figure 1 As shown, a rotatable, liftable, and movable wire ring storage trolley is provided for storing and transporting tire bead wire rings 3. Specifically, it includes a trolley assembly 1 and a placement assembly 2 installed on top of the trolley assembly 1.

[0023] like Figure 2 As shown, the trolley assembly 1 includes a frame body 11, with four sets of swivel casters 12 connected to the bottom of the frame body 11. A handlebar 13 is connected to one end of the frame body 11, and a horizontally arranged workbench 14 is installed on top of the frame body 11. The swivel casters 12 enable flexible transportation of the trolley, while the handlebar 13 and workbench 14 provide convenient movement and auxiliary operating conditions for the operator.

[0024] like Figures 3 to 4 As shown, a lifting mechanism 15 capable of driving the worktable 14 to move up and down is installed between the frame body 11 and the worktable 14. The lifting mechanism 15 includes a stand 151, with a drive sprocket 152 and a driven sprocket 153 located on the same side and capable of rotation, respectively, installed at the bottom and top of the stand 151. The drive sprocket 152 and the driven sprocket 153 are driven by a chain 154. A screw 156 mounted on a screw seat 155 is coaxially connected to the drive sprocket 152. One end of the screw 156 is connected to the lifting frame. A crank handle 157 is coaxially connected to the driven sprocket 153 on the screw seat 155. The operator can adjust the height of the worktable 14 according to their own height or operating needs, such as raising the worktable to a suitable position through the lifting mechanism 15, reducing bending over or tiptoeing during operation and improving working comfort.

[0025] like Figure 4 As shown, the lifting frame consists of two sets of equal-length, cross-arranged support arms 158. The two sets of support arms 158 are vertically arranged and movably connected by a horizontally arranged connecting rod 159. The bottom of one set of support arms 158 is supported above the frame body 11 by pulleys 1510, while the top of the other set of support arms 158 is supported below the worktable 14 by pulleys 1510. The lifting mechanism 15 converts the rotational motion of the crank handle 157 into the linear motion of the screw 156 via a chain 154-sprocket transmission, thereby driving the cross-support arms 158 to extend or retract, thus precisely controlling the lifting height of the worktable 14. The cross-support arm 158 structure provides stable support, ensuring the stability of the worktable 14 during lifting.

[0026] like Figures 5 to 6 As shown, the placement assembly 2 includes a vertically arranged column 21. Multiple placement mechanisms 22 are installed on the side wall of the column 21, which are arranged in a circumferential array and do not interfere with each other. The placement mechanism 22 includes three horizontally arranged placement frames. The three placement frames are arranged in a triangular pattern. Each placement frame has a rotatable pulley 223 installed inside the first and last ends. The two pulleys 223 in the same placement frame are driven by a belt 224. Each transmission belt has several evenly arranged grooves 225 on its outer surface away from the pulley 223, which allow the steel wire ring 3 to be placed. The steel wire rings 3 of the three placement racks can be driven by pulleys 223, making it easy to adjust the position of the steel wire rings 3. All steel wire rings 3 can be picked up and put down only at the outer end of the placement rack, which is more convenient. The triangular arrangement of the three placement racks forms a stable spatial layout. When each steel wire ring 3 is placed, it is constrained by the grooves 225 of the three conveyor belts, forming a three-point positioning of the steel wire ring 3. Compared with the traditional single-rod groove 225 suspension method, it significantly reduces the lateral and longitudinal sway of the steel wire ring 3, avoids accidental detachment or collision during the transfer process, and makes it more stable.

[0027] like Figures 7 to 11 As shown, the three storage racks consist of two fixed racks 221 and one sliding rack 222. The two fixed racks 221 are located above the column 21 and on the same horizontal plane, while the sliding rack 222 is located below the column 21 and between the two fixed racks 221. This layered layout can accommodate the storage needs of wire rings 3 of different diameters. Furthermore, based on mechanical principles, three-point positioning (such as an isosceles triangle) is the most stable planar constraint method. The constraint forces applied to the wire rings 3 by the grooves 225 in three directions can balance disturbance forces in any direction.

[0028] like Figures 7 to 11 As shown, a rocker arm 226 is provided between the two fixed placement racks 221, coaxially connecting the outermost pulley 223 inside the fixed placement rack 221. The belt 224 of the fixed placement rack 221 can be directly rotated by the rocker arm 226, and its position can be adjusted without contacting the steel wire ring 3, improving the safety and convenience of operation.

[0029] like Figures 7 to 11 As shown, a vertical sliding rod 227 connected to the column 21 is installed at the inner end of the sliding rack 222. A lifting slide 228 that can slide up and down is installed on the sliding rod 227, and the sliding rack 222 is entirely installed on the lifting slide 228. The vertical height of the sliding rack 222 can be adjusted by the lifting slide 228 to adapt to the storage needs of steel wire rings 3 of different specifications, thus enhancing its versatility.

[0030] like Figure 11 As shown, a horizontally arranged positioning pin 229 runs through the side of the lifting slide 228, and multiple positioning holes 2210 are evenly distributed along its axis and used to cooperate with the positioning pin 229 on the slide rod 227. After the positioning pin 229 is inserted into the positioning hole 2210, it can ensure that the sliding placement frame 222 is stably fixed after being adjusted to the target height, preventing the sliding frame from accidentally sliding down when the trolley moves, and ensuring the reliability of the storage of the wire ring 3.

[0031] like Figure 11 As shown, a horizontally arranged buffer slide 2211 is connected to the inner end of the sliding placement frame 222. The buffer slide 2211 is slidably mounted on a spring column 2212 that is vertically connected to the lifting slide 228. A buffer spring 2213 is fitted on the spring column 2212 to push the sliding slide downward. The buffer spring 2213 provides a downward preload, ensuring that the steel wire ring 3 on the sliding placement frame 222 always fits against the groove 225 of the belt 224, preventing it from shaking and coming off. At the same time, it absorbs the impact force when the trolley moves, improving stability.

[0032] like Figures 5 to 6As shown, a motor 23 is coaxially connected to the bottom of the column 21, and the entire column 21 can rotate horizontally under the drive of the motor 23. By rotating the column 21 through the motor 23, all the placement mechanisms 22 are driven to rotate synchronously, which makes it convenient for operators to pick up and put down the wire ring 3 from any angle without having to walk around the trolley, thus improving the efficiency of picking up and putting down.

[0033] Working principle of the invention: Storage of wire rings: The operator suspends the top of the wire ring 3 within the grooves 225 of the two fixed placement frames 221. Simultaneously, the operator adjusts the sliding placement frame 222 using the lifting slide 228 to accommodate the height of the wire ring 3, ensuring the bottom of the wire ring 3 rests against the groove 225 of the movable placement frame. The buffer spring 2213 ensures the wire ring 3 fits snugly against the groove 225. At this point, the three triangularly arranged placement frames form a stable spatial layout. Each wire ring 3 is constrained by the grooves 225 of the three conveyor belts, creating a three-point positioning for the wire ring 3. Figure 10 As shown, the position of the wire ring 3 can be adjusted by driving the belt 224 through the rocker arm 226, which significantly reduces the lateral and longitudinal sway of the wire ring 3, avoids accidental dislodgement or collision during the transfer process, and makes it more stable. In application, all wire rings 3 can be picked up and put down only at the outer end of the placement rack, which makes it more convenient to pick up and put down. Anti-sway and stability: The groove 225 of the belt 224 wraps the wire ring 3, and the buffer spring 2213 provides downward preload to prevent swaying when the trolley moves. The column 21 can be rotated by the motor 23, which makes it easy to pick up and put down the wire ring 3 from any angle. Cart movement: The swivel casters 12 support flexible transfer, and the height of the worktable 14 can be adjusted by the lifting mechanism 15 to adapt to operational needs. The lifting mechanism 15 converts the rotational motion of the crank handle 157 into the linear motion of the screw 156 through the chain 154-sprocket transmission, thereby driving the cross arm 158 to unfold or retract, thus precisely controlling the lifting height of the worktable 14. The cross arm 158 structure provides stable support to ensure the smoothness of the worktable 14 during the lifting process.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
