Description

Technical Field

[0001] This application relates to the field of optical fiber preform transportation technology, and in particular to an optical fiber preform transportation device. Background Technology

[0002] In the production of optical fiber preforms, the storage and handling of preforms are indispensable steps. Traditional large-scale production plants typically have dedicated storage rooms for purchased preforms. During production, these preforms need to be moved from the storage room to the production equipment. Traditional handling methods rely on the cooperation of multiple workers to move the preforms from the storage room to the transport mechanism for hoisting. While this method accomplishes the handling task, it still has some shortcomings.

[0003] First, traditional material handling methods require multiple workers, resulting in low efficiency and wasted time due to reliance on manual operation. Second, traditional methods typically occupy significant space, while production facilities have limited space, hindering efficient use of these limited work areas. This impacts production line turnover speed and overall production efficiency. Finally, relying on multiple operators not only increases labor costs and reduces production efficiency but also poses potential safety hazards and risks of personal injury.

[0004] Existing bar handling equipment is relatively simple in design, typically employing a single-layer structure that can only accommodate a small number of precast bars. Furthermore, most existing equipment still requires multiple people to complete the handling and hoisting operations. This makes it unsuitable for modern production plants, where these devices cannot meet the demands for high efficiency, space saving, and reduced reliance on manual labor. Therefore, existing technologies still have significant shortcomings in improving production efficiency, saving space, and reducing labor costs. Utility Model Content

[0005] To address the problems of low efficiency, large space occupation, and high dependence on manual labor in traditional rod transport methods, this application provides a fiber optic preform transport device.

[0006] The optical fiber preform transport device provided in this application adopts the following technical solution:

[0007] A fiber optic preform transport device, comprising:

[0008] The main frame has storage space;

[0009] A storage rack is vertically installed within the accommodating space. The storage rack includes multiple storage layers stacked along the height direction, and each storage layer is provided with multiple receiving slots for accommodating precast bars.

[0010] A moving mechanism, located at the bottom of the vehicle frame body, is used to move the vehicle frame body.

[0011] A hoisting mechanism is used for loading, unloading, and hoisting the precast bars.

[0012] By adopting the above technical solution, the device integrates the main frame, storage rack, moving mechanism, and lifting mechanism to achieve efficient handling and storage of precast bars during the production process. The main frame can be flexibly moved to different lifting positions, and the lifting mechanism accurately and safely transfers the precast bars from the storage rack to the production equipment. The storage rack adopts a multi-layer design to optimize vertical space, improve storage capacity, and ensure the stability of the precast bars during handling. This device can improve handling efficiency, reduce manual intervention and operational errors, optimize storage conditions, reduce downtime, improve production line efficiency, and enhance the safety and overall efficiency of the production environment.

[0013] In one specific implementation, each storage layer has multiple receiving slots on its upper and lower sides; wherein, the receiving slot at the top serves as the receiving position for the preformed rod alone, the receiving slots between two adjacent storage layers can jointly serve as the receiving position for the preformed rod, and the receiving slot at the bottom can jointly serve as the receiving position for the preformed rod with the bottom wall of the accommodating space.

[0014] By adopting the above technical solution, and utilizing the combination of receiving slots on both the top and bottom sides, as well as the receiving slots between adjacent storage layers, the design of the storage space can be optimized, fully tapping the storage potential of the space. The separate receiving slot at the top ensures the stable placement of the precast bars and facilitates frequent operations. The design of using the receiving slots of the upper and lower storage layers together improves the stability of the precast bars placed in the middle position. The design of the receiving slot at the bottom, which is integrated with the bottom wall, ensures stability and prevents the precast bars stored at the bottom from tilting or being damaged during transportation. The receiving slots at different levels and positions can be adjusted to place the precast bars according to actual needs, making the transportation of each layer more convenient and faster.

[0015] In one specific implementation, the accommodating space has a fixed slot extending along the height direction on its inner wall, the fixed slot being correspondingly provided with the storage rack, wherein a plurality of storage layers are sequentially installed in the fixed slot along the height direction, and the two sides of the storage layers are slidably embedded in the fixed slot.

[0016] By adopting the above technical solution, the storage layer is slidably embedded in the fixed slot on both sides, which not only facilitates the installation and disassembly of the storage layer, but also allows the storage layer to be flexibly adjusted in position within the slot according to actual needs; at the same time, since the storage layer can be slidably installed in the slot, users can adjust the height of each storage layer according to the height requirements of precast bars of different sizes, meeting the storage needs of different precast bars and increasing the flexibility and practicality of the storage rack.

[0017] In one specific implementation, a plurality of fixing screws are also included, which pass through the sidewall of the fixing slot and connect to the storage layer.

[0018] By adopting the above technical solution, the design of fixing screws and sliding slots is combined. The fixing screws connect the storage layer to the side wall of the fixing slot, so that the storage layer can be firmly fixed in the fixing slot. This ensures that the storage layer will not be displaced or loosened due to external forces during use, thereby ensuring the safety and durability of the storage rack.

[0019] In one specific implementation, the storage racks are provided in multiple locations, which are evenly distributed along the length of the accommodating space and are used together to place the precast rods.

[0020] By adopting the above technical solution, multiple storage racks are evenly arranged along the length of the storage space to form a collaborative working mechanism, ensuring the stable storage of precast bars and improving space utilization. By distributing multiple storage racks to share the storage function, the weight and pressure of the precast bars can be shared, improving the stability of the overall structure and adapting to storage needs of different sizes and weights.

[0021] In one specific implementation, the hoisting mechanism includes a truss spanning above the main frame and an electric hoist slidably mounted on the truss, the electric hoist being connected to the precast bar to drive the precast bar to lift and lower.

[0022] By adopting the above technical solution, and utilizing the cooperation between the truss and the electric hoist, the electric hoist can slide on the truss, making the lifting operation range wider and adaptable to different lifting positions; the electric drive of the electric hoist can control the lifting and lowering of the precast bars, ensuring that the precast bars can be stably lifted or lowered during operation, thereby ensuring the safety and efficiency of the operation.

[0023] In one specific implementation, the electric hoist includes a motor, a controller, a chain, and a hook disposed on the chain. The controller is electrically connected to the motor and is used to control the start, stop, and speed of the motor. The motor is used to drive the chain to lift and lower. The hook is detachably connected to the precast bar via a strap.

[0024] By adopting the above technical solution, the chain is driven by an electric motor for lifting and lowering. The hooks on the chain are detachably connected to the precast bars via straps, forming an efficient, flexible and safe lifting system. The detachable connection of the hooks to the precast bars via straps makes the lifting operation more flexible, the replacement of the lifted object is faster, and the operation time is saved, thereby ensuring the efficiency and convenience of the lifting operation, while maintaining a high level of safety and reliability.

[0025] In one specific implementation, the inner surface of the receiving groove is provided with an elastic cushioning pad.

[0026] By adopting the above technical solution, the elastic buffer pad inside the receiving tank can not only effectively absorb external impacts and reduce the impact of vibration on the object, but also protect the surface of the precast rod, preventing scratches, indentations or other physical damage, thereby improving the safety and protection of the contained object.

[0027] In one specific implementation, the moving mechanism includes a plurality of casters disposed at the bottom of the frame body, and the casters are equipped with brakes.

[0028] By adopting the above technical solutions, the design of the omnidirectional wheels allows the frame to move freely in multiple directions, providing greater maneuverability and flexibility; the addition of brakes can lock the position of the frame when it stops, preventing the frame from sliding on its own when not in use, thus ensuring safety, stability and convenience during operation.

[0029] In one specific implementation, the frame body is also provided with a pushcart handle.

[0030] By adopting the above technical solution, the trolley handle allows the operator to manually push or guide the frame to move. The operator can easily move the frame body within the work area to quickly reach the hoisting position or other designated areas.

[0031] In summary, the beneficial technical effects of this application are as follows: by integrating multiple functional modules such as the chassis body, storage rack, moving mechanism, and lifting mechanism, efficient handling and storage of precast bars are achieved during the production process; the chassis body can be flexibly moved to different lifting positions through the moving mechanism, and the lifting mechanism can accurately and safely lift the precast bars from the storage rack and transport them to the production equipment; the storage rack adopts a multi-layer design, and through the combination of the upper and lower receiving slots and adjacent layers, the utilization of vertical space is optimized, storage capacity is improved, and the stability and safety of the precast bars during handling are ensured;

[0032] The hoisting mechanism uses a combination of truss and electric hoist. The electric hoist improves the flexibility and range of hoisting through a sliding mechanism, thereby increasing handling efficiency and reducing the risk of human intervention and operational errors. At the same time, by optimizing storage space and the high efficiency of the equipment, the working efficiency and production continuity of the production line are improved, ensuring the safe and stable handling and storage of optical fiber preforms throughout the entire production process.

[0037] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0038] Reference Figure 1-3 This application discloses an optical fiber preform transport device, comprising:

[0039] The frame body 1 is the basic frame of the bar-carrying device in this embodiment, and constitutes the support structure of the entire device. The frame body 1 is provided with a accommodating space 11.

[0040] The moving mechanism 3 is located at the bottom of the frame body 1 and is used to move the frame body 1.

[0041] Storage rack 2 is vertically installed in the accommodating space 11 for storing precast rods 7. Storage rack 2 includes multiple storage layers 21 stacked along the height direction. Storage layers 21 are provided with multiple receiving slots 22 for accommodating precast rods 7.

[0042] Lifting mechanism 4 is used for loading, unloading and lifting precast bars 7;

[0043] During operation, the main body 1 of the vehicle frame is moved to the corresponding hoisting position by the moving mechanism 3, and the precast bars 7 are hoisted by the hoisting mechanism 4. The precast bars 7 are hoisted one by one from the storage bar room into the receiving slots 22 on the storage rack 2. After the hoisting is completed, the main body 1 of the vehicle frame is moved to the production workshop by the moving mechanism 3, and the precast bars 7 are hoisted from the storage rack 2 onto the production equipment by the hoisting mechanism 4.

[0044] By integrating the moving mechanism 3, the hoisting mechanism 4, and the multi-layer storage rack 2, the preform 7 is efficiently and safely handled and stored during the production process. The moving mechanism 3 flexibly moves the frame body 1 to the hoisting position, ensuring that the hoisting mechanism 4 can accurately lift and safely transfer the preform 7 from the storage room to the receiving slot 22 on the storage rack 2. Then, the frame body 1 is moved again to send the preform 7 to the production workshop for processing. This device effectively improves handling efficiency, reduces manual intervention, and lowers the risk of human error. By fully utilizing vertical space through the layered stacking of the storage rack 2, it optimizes storage conditions, not only improving the handling and storage capacity of the optical fiber preform 7, but also enhancing the overall safety and efficiency of production.

[0045] In this embodiment, multiple storage shelves 2 are provided, which are evenly distributed along the length of the accommodating space 11 and are used together to place the precast rods 7. That is, the precast rods 7 can be placed across multiple storage shelves 2. The multiple storage shelves 2 are evenly arranged along the length of the accommodating space 11 to form a collaborative working mechanism, ensuring the stable storage of the precast rods 7 and improving space utilization. By distributing multiple storage shelves 2, the storage shelves 2 share the storage function, which can evenly distribute the weight and pressure of the precast rods 7, reduce the burden on a single storage shelf 2, improve the stability of the overall structure, and adapt to storage needs of different sizes and weights.

[0046] The accommodating space 11 has a fixed slot 12 extending along the height direction on its inner wall, and the fixed slot 12 is provided one-to-one with the storage rack 2; in the storage rack 2, multiple storage layers 21 are installed in the fixed slot 12 in sequence along the height direction, and the two sides of the storage layer 21 are slidably embedded in the fixed slot 12.

[0047] It also includes multiple fixing screws 5, which pass through the side wall of the fixing slot 12 and are connected and fixed to the storage layer 21; thereby ensuring that the storage layer 21 can be firmly fixed in the fixing slot 12, ensuring that the storage layer 21 will not be displaced or loosened due to external force during use.

[0048] The combination of the fixing screw 5 and the sliding slot design not only facilitates the installation and disassembly of the storage layer 21, but also ensures the installation stability of the storage layer 21, and allows the storage layer 21 to be flexibly adjusted in position according to actual needs; at the same time, users can adjust the height of each storage layer 21 according to the height requirements of different sizes of precast bars 7, to meet the storage needs of different precast bars 7, and increase the flexibility and practicality of the storage rack 2.

[0049] In this embodiment, each storage rack 2 is provided with two storage layers 21, and the specific number of storage layers 21 can be designed according to the actual situation; each storage layer 21 is provided with two receiving slots 22 on the upper and lower sides; among them, the receiving slot 22 located at the top can be used as a separate receiving position for the preformed rod 7, ensuring that the preformed rod 7 is placed stably, which is suitable for scenarios that require frequent operation, because the top receiving slot 22 facilitates quick access and reduces the complexity of operation;

[0050] The receiving slots 22 of the upper and lower storage layers 21 are used together. The adjacent receiving slots 22 between the upper and lower storage layers 21 are connected and arranged. The adjacent receiving slots 22 between the upper and lower storage layers 21 can be used together as receiving positions for the preformed rod 7. The two receiving slots 22 can be used together to hold and fix the preformed rod 7, providing additional support for the preformed rod 7 in the middle position, enhancing its stability, so that the preformed rod 7 in the middle layer is not easily affected by external factors during storage, avoiding tilting or damage caused by improper operation.

[0051] The receiving groove 22 located at the bottom can be used together with the bottom wall of the receiving space 11 as the receiving position of the precast bar 7. The bottom receiving groove 22 and the bottom wall are used together to ensure that the precast bar 7 stored at the bottom will not tilt or slide due to external force. This not only increases stability, but also reduces the risk of the precast bar 7 being damaged during the movement of the frame body 1, ensuring safe and reliable transportation.

[0052] The receiving slots 22 at different levels and positions can flexibly adjust the placement of the precast bars 7 according to actual needs, making it easier and faster to transport the precast bars 7 at each level. The storage method at different positions can be adjusted according to actual operation requirements, improving the flexibility and efficiency of operation.

[0053] In this embodiment, the appropriate loading and unloading scheme can be selected according to the number of precast bars 7 transported in a single shipment. If all the receiving positions need to be filled, the bottom receiving position is loaded first. Specifically, two precast bars 7 are first hoisted into the receiving space 11 by the hoisting mechanism 4 and abutted against its bottom wall. Then, the two sides of one of the storage layers 21 are slidably embedded in the fixing slots 12, ensuring that the receiving slots 22 at the bottom of the storage layer 21 are correspondingly locked onto the two precast bars 7, forming the bottom receiving position with the bottom wall of the receiving space 11. Then, two more precast bars 7 are hoisted onto the receiving slots 22 at the top of the storage layer 21. The two sides of the other storage layer 21 are slidably embedded in the fixed slot 12, ensuring that the receiving slot 22 at the bottom of the other storage layer 21 is correspondingly locked on the two precast rods 7, forming an intermediate layer receiving position together with the receiving slot 22 at the top of the previous storage layer 21; continue to hoist the two precast rods 7 to the receiving slot 22 at the top of the top storage layer 21, ensuring that the precast rods 7 are stably housed in the receiving slot 22, forming the top layer receiving position; if the quantity transported in a single trip is less than the total number of receiving positions, the corresponding loading and unloading scheme can be selected according to actual needs, and the specific operation process can refer to the above scheme.

[0054] In this embodiment, the inner surface of the receiving groove 22 is provided with an elastic buffer pad. The elastic buffer pad can not only effectively absorb external impacts and reduce the impact of vibration on the object, but also protect the surface of the preform 7, prevent scratches, indentations or other physical damage, and improve safety and protection.

[0055] The hoisting mechanism 4 is located on the upper part of the frame body 1. The hoisting mechanism 4 includes a truss 41 and an electric hoist 42 mounted on the truss 41. The truss 41 spans the upper part of the frame body 1 and can provide sufficient space and support for hoisting operations. The electric hoist 42 is slidably mounted on the truss 41 and can move within a certain range to adapt to the needs of different hoisting positions.

[0056] The electric hoist 42 includes a motor 43, a controller 47, a chain 44, and a hook 45 on the chain 44. The controller 47 is electrically connected to the motor 43. The controller 47 is equipped with a button for controlling the start, stop, and speed of the motor 43, thereby controlling the lifting speed. The motor 43 drives the chain 44 to move up and down. The hook 45 on the chain 44 is detachably connected to the precast bar 7 via a strap 46, thereby realizing the lifting operation of the precast bar 7.

[0057] The electric hoist 42 is lifted and lowered by driving the chain 44 during operation. The detachable connection between the hook 45 and the strap 46 makes the lifting operation more flexible, the replacement of the object being lifted is faster, and the safety and stability of the lifting are ensured. The design of the electric hoist 42 improves the flexibility and range of the lifting operation, and can stably lift or lower the precast bar 7, ensuring the safety and efficiency of the lifting process. The design of the electric hoist 42 also makes it convenient to lift precast bars 7 of different weights, which can meet the requirements of high-frequency operation.

[0058] The moving mechanism 3 includes several casters 31, which are evenly arranged at the bottom of the frame body 1. The design of the casters 31 allows the frame to move freely in multiple directions, providing greater mobility and flexibility.

[0059] The caster wheel 31 is equipped with a brake (not shown in the figure), which is a foot-operated linkage brake. When it is necessary to stop, the position of the caster wheel 31 can be easily locked by foot operation, ensuring that the frame body 1 will not slide on its own when not in operation, thus ensuring the safety and stability of operation. In addition, the design of the foot-operated linkage brake allows the operator to easily start or release the brake without bending over or using hand strength, so that the frame body 1 can stop or move quickly and stably, simplifying the operation process and improving work efficiency.

[0060] To facilitate the movement of the frame body 1 within the work area, the frame body 1 is also equipped with a trolley handle 6. The design of the trolley handle 6 allows the operator to manually push or guide the frame to move quickly to the hoisting position or other designated areas.

[0061] The implementation principle of this application embodiment is as follows: During operation, the operator manually pushes the frame through the trolley handle 6. The design of the universal wheel 31 allows the frame to move freely in multiple directions, enabling it to smoothly reach the hoisting position. When it is necessary to stop, the operator locks the universal wheel 31 through the foot brake to ensure that the frame body 1 remains stable.

[0062] After the main body 1 of the vehicle frame reaches the hoisting position, the hoisting mechanism 4 starts working through the truss 41 and the electric hoist 42. The electric hoist 42 is moved by sliding. The electric hoist 42 slides to the target position on the truss 41 and uses the binding strap 46 to tie the precast bar 7. Then the hook 45 of the electric hoist 42 is connected to the binding strap 46 to complete the fixation. The electric hoist 42 controls the motor 43 to start and adjust its speed through the controller 47, thereby driving the chain 44 to rise or fall, ensuring that the precast bar 7 can be lifted safely and accurately. The operator lifts the precast bar 7 from the storage room through the hoisting mechanism 4 and accurately places it into the receiving slot 22 on the storage rack 2.

[0063] When loading the precast bars 7, the hoisting mechanism 4 hoists the precast bars 7 sequentially into the receiving slots 22 of each storage layer 21. If all receiving slots need to be filled, the operator will first fill the receiving slots 22 of the bottom layer, and then hoist them upwards layer by layer until all the receiving slots 22 of the storage layers 21 are filled. During this process, the receiving slots 22 of each storage layer 21 are connected to the fixing slots 12 by fixing screws 5 to ensure that the storage layers 21 will not shift during hoisting, thus ensuring the stable storage of the precast bars 7.

[0064] After hoisting, the main body 1 of the chassis is moved to the production workshop again by the moving mechanism 3, ready to transport the precast bars 7 to the production equipment. During the transportation process, the chassis can be flexibly adjusted in direction by the design of the universal wheels 31 to ensure smooth transportation. After arriving at the production workshop, the hoisting mechanism 4 is started again, and the electric hoist 42 is used to hoist the precast bars 7 from the storage rack 2 to the production equipment, completing the task of transporting the precast bars 7.

[0065] This embodiment of the application integrates a moving mechanism 3, a hoisting mechanism 4, and a multi-layer storage rack 2 to achieve efficient and safe handling and storage of optical fiber preforms 7 during the production process. The main body 1 of the device serves as a support structure, and in conjunction with the moving mechanism 3, the main body can be flexibly moved to the hoisting position, ensuring that the hoisting mechanism 4 can accurately lift the preforms 7 and safely transfer them from the storage room to the receiving slots 22 on the storage rack 2. Subsequently, the preforms 7 are sent to the production workshop for processing by moving the main body 1. The storage rack 2 adopts a multi-layer design, and by combining the receiving slots 22 on the upper and lower sides and the adjacent layers, the utilization of vertical space is optimized, the storage capacity is improved, and the stability and safety of the preforms 7 during the handling process are ensured.

[0066] This rod transport device greatly improves handling efficiency, reduces manual intervention, and lowers the risk of human error. The hoisting mechanism 4 adopts an electric hoist 42 and a sliding truss 41 design, which improves the flexibility and efficiency of hoisting operations, can adapt to different hoisting needs, and ensures the safety and reliability of the hoisting process. In summary, this device not only optimizes the handling and storage capacity of optical fiber preforms, but also improves the safety, efficiency, and flexibility of the production environment.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
