Technical Field

[0002] The connecting ring, also known as the Hejie ring, is a component used to connect the connecting parts on mechanical or electrical equipment, especially for connecting two metal round pipes on refrigeration equipment. In refrigeration systems such as refrigerators and air conditioners, the pipe materials in each functional area are often different, such as copper pipes and aluminum pipes. They need to be seamlessly butted to form a refrigerant circulation loop. The connecting ring, in combination with cold extrusion connection technology, can connect metal pipes of different materials together to achieve the effect of seamless connection.

[0003] The processing technological process of the connecting ring mainly includes: raw material preparation, cutting and blanking, lathe processing, cold extrusion forming, surface treatment, quality inspection, packaging and warehousing, etc. These processing processes are usually completed at different locations or even on different floors. Therefore, for the completed or uncompleted connecting rings, transportation is required between various locations. When the existing connecting rings are transported between different floors, they are usually transported by an elevator. The entire transportation process requires workers to follow and operate throughout. Due to the limited capacity of the elevator, if the number of connecting rings is large, multiple round-trip transports may be required, and the peak usage period of the elevator needs to be considered during use to avoid affecting the normal use of other people. Therefore, there are many inconveniences in transporting connecting rings by elevator. Summary of the Invention

A winding assembly is arranged on the electric sliding assembly. The other end of the steel wire rope is wound on the winding assembly. Induction parts are arranged at the turning points of the chain drive assembly. The electric sliding assembly and the induction parts are both electrically connected to the control system. The electric sliding assembly is used to keep the winding assembly directly above the first transportation platform all the time. The winding assembly always tightens the steel wire rope. The induction parts are used to sense the position of the first transportation platform.

[0012] Optionally, a vertically arranged counterweight block is fixedly connected to the second end of the bearing shaft.

[0013] Optionally, a second transportation platform is fixedly connected to the second end of the bearing shaft. The structure of the second transportation platform is the same as that of the first transportation platform, and the second transportation platform and the first transportation platform are symmetrically distributed with respect to each other.

[0016] Material preparation: Pack the materials. The packed materials are placed at the fixed part of the first conveying assembly for input.

[0017] Adjustment of the first conveying assembly for input: The movable part corresponding to the first conveying assembly rotates to be flush with the fixed part, and the material moves towards the movable part.

[0018] Material input: The control system controls the chain drive assembly to start, and drives the first transportation platform to move upward from bottom to top towards the material. Since the multiple movable rods and the multiple bearing rods are staggeredly distributed, the moving bearing rods will pass through the gaps between the movable rods, and the material is input onto the first transportation platform.

[0019] Adjustment of the first conveying assembly for output: The movable part of the first conveying assembly for output on the target floor rotates to be flush with the fixed part.

[0020] Material output: The chain drive assembly drives the first transportation platform to move downward from top to bottom towards the first conveying assembly for output on the target floor. Since the multiple movable rods and the multiple bearing rods are staggeredly distributed, the moving bearing rods will pass through the gaps between the movable rods, and the material is output onto the first conveying assembly for output on the target floor.

[0021] The technical solution of the present application is through setting a chain transmission component, a first transport platform, a first conveying component, and a control system.

The plurality of movable rods and the plurality of load-bearing rods are staggered with each other. After the control system is started, the chain transmission component is controlled to run, driving the first transport platform to move between multiple floors. When the first transport platform moves to a specific floor, the corresponding floor The first conveying component can input or output materials for the first transport platform according to actual needs. If the floor is the starting floor of the materials, the first conveying component will transport the materials to the first transport platform. If the floor is the target floor of the materials, the first conveying component will receive the materials from the first transport platform. When the materials are input or output, since the multiple movable rods and the multiple load-bearing rods are staggered, the movable load-bearing rods will pass through the gaps between the movable rods, thereby realizing the input or output of the materials. When used specifically, the chain drive component can always drive the first transport platform to move. It only needs to unfold the movable parts of the input first conveying component of the starting floor and the output first conveying component of the target floor.

[0036] The processing technological process of the connecting ring mainly includes: raw material preparation, cutting and blanking, lathe processing, cold extrusion forming, surface treatment, quality inspection, packaging and warehousing, etc. These processing processes are usually completed at different locations or even on different floors. Therefore, for the completed or uncompleted connecting rings, transportation is required between various locations. When the existing connecting rings are transported between different floors, they are usually transported by an elevator. The entire transportation process requires workers to follow and operate throughout. Due to the limited capacity of the elevator, if the number of connecting rings is large, multiple round trips of transportation may be required, and the peak usage period of the elevator needs to be considered during use to avoid affecting the normal use of other people. Therefore, there are many inconveniences in transporting connecting rings by elevator.

[0037] In view of this, the present application proposes a vertical material transportation device and method.

[0038] In an embodiment of the present application, with reference to Figures 1 to 4 , the above-mentioned vertical material transportation device includes: a chain drive assembly 1, a first transportation platform 2, a first conveying assembly 3, and a control system. The chain drive assembly 1 is arranged between multiple floors and is used to drive the first transportation platform 2 to move. The first transportation platform 2 is used to place materials. Specifically, the material is a connecting ring, which is loaded into a rectangular storage box during transportation. The first conveying assembly 3 is arranged on both sides of the chain drive assembly 1 corresponding to each floor and is used to input or output materials to or from the first transportation platform 2. The control system is used to control the operation of the chain drive assembly 1. The chain 102 in the chain drive assembly 1 meshes with the sprocket 101, and the rotation of the sprocket 101 drives the chain 102 to perform a cyclic motion. Since the first transportation platform 2 is connected to the chain 102, the movement of the chain 102 will be transmitted to the first transportation platform 2, enabling it to move in the vertical direction.

[0039] The first transportation platform 2 includes a carrier 210, and the carrier 210 is rotatably installed on the chain drive assembly 1. A plurality of carrier rods 220 are arranged on one side of the carrier 210 facing the first conveying assembly 3, and the plurality of carrier rods 220 jointly carry the materials. The first conveying assembly 3 includes a fixed part 310 and a movable part 320. The fixed part 310 is fixedly installed on the corresponding floor, and the movable part 320 is rotatably connected to the fixed part 310. The movable part 320 includes a movable frame 321, and a plurality of movable rods 322 are arranged on one side of the movable frame 321 facing the first transportation platform 2. The plurality of movable rods 322 and the plurality of carrier rods 220 are staggeredly distributed. The movable part 320 of the first conveying assembly 3 is rotatable. When the movable part 320 rotates to a suitable position, the movable rods 322 on the movable frame 321 and the carrier rods 220 on the carrier 210 are interlaced with each other, enabling the materials to smoothly transition between the movable rods 322 and the carrier rods 220, thereby realizing the transfer of materials between the first conveying assembly 3 and the first transportation platform 2.

[0040] With reference to Figure 1 , Figure 2 , at both ends of the carrier 210 and above the carrier rods 220, first baffles 240 are arranged. The first baffles 240 are fixedly connected to the corresponding carrier rods 220 and are used to prevent the materials from falling from both ends of the carrier 210 during transportation. A second baffle 323 is fixedly installed at one end of the movable part 320 close to the chain drive assembly 1, and the second baffle 323 is used to prevent the materials from rushing out of the first conveying assembly 3 due to inertia when moving towards the chain drive assembly 1.

[0041] It should be noted that with reference to Figure 1, when the chain drive assembly 1 rotates clockwise, the first conveying assembly 3 on the left side of the chain drive assembly 1 is the first conveying assembly 3 for input, and the first conveying assembly 3 on the right side of the chain drive assembly 1 is the first conveying assembly 3 for output. That is, the material is conveyed to the first conveying platform via the first conveying assembly 3 on the left side, and the material is conveyed to the target floor via the first conveying assembly 3 on the right side. Similarly, when the chain drive assembly 1 rotates counterclockwise, the first conveying assembly 3 on the right side of the chain drive assembly 1 is the first conveying assembly 3 for input, and the first conveying assembly 3 on the left side of the chain drive assembly 1 is the first conveying assembly 3 for output, so as to ensure that the material can be smoothly transported from the initial floor to the target floor. During specific use, it can be adjusted according to the actual situation.

[0042] Reference Figure 3 , the fixing part 310 includes two symmetrically arranged frames 311. A plurality of rollers 312 evenly distributed along the frame 311 are rotatably installed between the two frames 311. The movable rod 322 is rotatably installed on the movable frame 321, and the movable frame 321 is rotatably connected to the frame 311. A first driving assembly is provided between the movable frame 321 and the frame 311. The first driving assembly is electrically connected to the control system. The first driving assembly is used to drive the movable frame 321 to rotate and make the movable frame 321 flush or perpendicular to the frame 311. The control system sends corresponding electrical signals to the first driving assembly according to the requirements of material transportation. After receiving the signal, the first driving assembly converts electrical energy into mechanical energy and drives the movable frame 321 to rotate around the connection point with the frame 311. The movable frame 321 can be switched between two states of being flush and perpendicular to the frame 311. When material input or output is required, the movable frame 321 rotates to a state flush with the frame 311, so that the material can smoothly move between the movable rod 322 and the rollers 312 of the fixing part 310. When material transportation is not required, the movable frame 321 can rotate to a state perpendicular to the frame 311 to avoid interfering with material transportation.

[0043] Specifically, the height of the end of the first conveying component 3 for input that is far from the chain drive component 1 is greater than the height of the end close to the chain drive component 1, and the height of the end of the first conveying component 3 for output that is close to the chain drive component 1 is greater than the height of the end far from the chain drive component 1; specifically, according to the actual situation, one end of the first conveying component 3 can be elevated, or the support member under the frame 311 can be set as an adjustable structure, for example, a screw adjustment structure (prior art); when feeding materials, since the height of the end of the first conveying component 3 for input that is far from the chain drive component 1 is greater than the height of the end close to the chain drive component 1, after the materials are placed on the fixed part 310 of the conveying component, under the action of gravity, they will automatically roll towards the direction of the first transport platform 2 along the inclined conveying component; when the first transport platform 2 reaches the target floor for material output, since the height of the end of the first conveying component 3 for output that is close to the chain drive component 1 is greater than the height of the end far from the chain drive component 1, at this time, under the action of gravity, the materials will roll from the movable rod 322 of the first conveying component 3 onto the roller 312 of the fixed part 310 and finally reach the designated position on the target floor; using gravity as the power for material transportation eliminates the need for additional power equipment (such as motors, etc.) to push the materials to move, greatly saving energy consumption, reducing operating costs, reducing manual intervention, simplifying the operation process of material transportation, improving the degree of automation of transportation, and making the entire transportation process more efficient and convenient.

[0044] Reference Figure 1 , the chain drive component 1 includes two sprockets 101 and a chain 102 that are distributed vertically. One of the sprockets 101 is installed above the highest floor to be transported through a support member, specifically, it can be the ceiling of this floor or a higher floor. The other sprocket 101 is installed below the lowest floor to be transported through a support member, specifically, it can be the next floor below this floor. If it is the first floor, it can be installed underground, specifically, it can refer to the elevator shaft. The chain 102 is arranged outside the two sprockets 101, and the chain 102 meshes with the sprockets 101. One of the sprockets 101 is connected to the second drive component, and the second drive component is electrically connected to the control system. The second drive component is used to drive the sprocket 101 to rotate; the chain drive transmits the power of the second drive component to the first transport platform 2, enabling it to move stably between floors; the chain drive has a high transmission efficiency, can efficiently transmit the power of the second drive component to the first transport platform 2, reduces energy loss, improves the overall operating efficiency of the equipment, and the chain drive can withstand a large load and is suitable for transporting heavier materials.

[0045] Specifically, the second drive component can be composed of a drive motor and a reducer. The drive motor is connected to the sprocket 101 through the reducer, and the reducer can increase the torque so that the chain drive component 1 can withstand a greater load.

[0046] Reference Figure 2 In addition, the first transportation platform 2 further includes two mounting rods 230 disposed obliquely above the bearing member 210. The first ends of the two mounting rods 230 intersect and are fixedly connected to the first end of the bearing shaft 8. The second end of the bearing shaft 8 penetrates through the chain 102 and is rotatably connected thereto. The second ends of the two mounting rods 230 are respectively fixedly connected to both ends of the bearing member 210. The oblique setting of the mounting rods 230 forms a stable triangular structure between the bearing member 210 and the bearing shaft 8. During the movement of the first transportation platform 2, this structure can effectively disperse the force received by the bearing member 210, reduce the swaying and vibration of the bearing member 210, and maintain the stability of the first transportation platform 2. In addition, since the triangle formed by the mounting rods 230 is located above the bearing member 210, that is, the center of gravity of the transportation platform and the material is lower than the position where the mounting rods 230 are connected to the chain 102, the first transportation platform 2 is not prone to swaying during movement; this design enhances the connection stability between the first transportation platform 2 and the chain drive assembly 1, ensures the reliable transmission of power, enables the first transportation platform 2 to better adapt to the movement of the chain 102, and reduces swaying and vibration.

[0047] Reference Figure 1 And Figure 2 Above the bearing member 210, two pull rods 4 are also disposed obliquely. The first ends of the two pull rods 4 intersect and are fixedly connected to one end of the steel wire rope 5. The second ends of the two pull rods 4 are respectively fixedly connected to both ends of the bearing member 210. Above the chain drive assembly 1, an electric sliding assembly 6 is horizontally provided. A winding assembly 7 is provided on the electric sliding assembly 6. The other end of the steel wire rope 5 is wound on the winding assembly 7. Inductive members are provided at the turning points of the chain 102 drive assembly. The electric sliding assembly 6 and the inductive members are both electrically connected to the control system. The electric sliding assembly 6 is used to keep the winding assembly 7 always directly above the first transportation platform 2, and the winding assembly 7 always tightens the steel wire rope 5. The inductive members are used to sense the position of the first transportation platform 2; the inductive members are installed at the turning points of the chain 102 drive assembly, and can monitor the position of the first transportation platform 2 in real time. When the first transportation platform 2 approaches the turning point, the inductive members will detect its position information and convert this information into an electrical signal and transmit it to the control system. After receiving the signal from the inductive members, the control system analyzes and processes the signal, and then sends a control instruction to the electric sliding assembly 6. The electric sliding assembly 6 moves according to the instruction, so that the winding assembly 7 is always directly above the first transportation platform 2. After the winding assembly 7 moves to a suitable position under the drive of the electric sliding assembly 6, it always maintains the state of tightening the steel wire rope 5. By tightening the steel wire rope 5, the attitude of the first transportation platform 2 is adjusted. The steel wire rope 5 generates an upward pulling force on the first transportation platform 2. When the first transportation platform 2 sways or tilts, the pulling force of the steel wire rope 5 can play a balancing role to keep it stable and reduce its swaying during movement.

[0048] Specifically, the electric sliding assembly 6 can be composed of a motor, a lead screw and nut mechanism, or a linear guide and a slider, etc. (prior art). The motor provides power. The lead screw and nut mechanism can convert the rotational motion of the motor into a linear motion. The linear guide provides guidance for the movement of the slider to ensure the accuracy and stability of its movement.

[0049] Specifically, the winding assembly 7 can be composed of a drum, a motor, a speed reducer, etc. (prior art). The drum is used to wind the steel wire rope 5. The motor provides power. The speed reducer plays a role in reducing the speed and increasing the torque to ensure that the drum can stably wind or release the steel wire rope 5. Specifically, reference can be made to the winch on a crane for winding the steel wire rope 5.

[0050] Specifically, the sensing element can be one of a photoelectric sensor or a proximity sensor (prior art). Specifically, reference can be made to the infrared sensing device beside an elevator door.

[0051] Reference Figure 4 , which is the first embodiment of the vertical material transportation device in this solution. Specifically, a vertically arranged counterweight 9 is fixedly connected to the second end of the bearing shaft 8; the counterweight 9 is connected to the first transportation platform 2 through the bearing shaft 8. During the movement of the first transportation platform 2, the counterweight 9 will move together with the first transportation platform 2. When the first transportation platform 2 rises or falls, the gravity of the counterweight 9 will generate a reverse acting force on the first transportation platform 2, playing a balancing role, thereby reducing the uneven force on the chain 102 and the sprocket 101 and reducing the wear of the chain drive assembly 1; in addition, the balancing role of the counterweight 9 improves the smoothness of the movement of the first transportation platform 2, reduces the shaking and vibration of the first transportation platform 2 during the movement process, and further ensures the safety of material transportation.

[0052] Reference Figure 5 , which is the second embodiment of the vertical material transportation device in this solution. Specifically, a second transportation platform 10 is fixedly connected to the second end of the bearing shaft 8. The structure of the second transportation platform 10 is the same as that of the first transportation platform 2, and the second transportation platform 10 and the first transportation platform 2 are symmetrically distributed with respect to each other; the bearing shaft 8, as a component connecting the first transportation platform 2 and the second transportation platform 10, transmits the power of the chain drive assembly 1 to both transportation platforms simultaneously, realizing the synchronous movement of the two. Both transportation platforms can be used for transporting materials, increasing the efficiency of material transportation and enabling more materials to be transported simultaneously; the second transportation platform 10 and the first transportation platform 2 have the same structure and are symmetrically distributed with respect to each other. The symmetrical arrangement of the two transportation platforms can balance each other's weight and movement inertia, making the force on the two transportation platforms more uniform during the movement process, reducing the shaking and deviation caused by unilateral force, and improving the overall stability and reliability of the equipment.

[0053] Specifically, a second conveying assembly (not shown in the figure) is provided near the first conveying assembly 3 on each floor. The structure of the second conveying assembly is the same as that of the first conveying assembly 3, and the second conveying assembly and the first conveying assembly 3 are symmetrically distributed with each other; the second conveying assembly and the first conveying assembly 3 on each floor are symmetrically distributed and have the same structure. During the material transportation process, the second conveying assembly cooperates with the second transport platform 10, and the first conveying assembly 3 cooperates with the first transport platform 2. When the chain transmission assembly 1 drives the first transport platform 2 and the second transport platform 10 to move to the corresponding floors, the first conveying assembly 3 and the second conveying assembly respectively perform material input or output operations for the first transport platform 2 and the second transport platform 10; during the material transportation process, the two conveying assemblies can perform material input and output operations at the same time, further improving the transportation efficiency.

[0054] A vertical material transportation method, using the vertical material transportation device, comprises:

[0055] Material preparation, packing the materials into boxes for easy handling and transportation, placing the boxed materials in the fixed part of the first conveying assembly for input, waiting for subsequent transportation operations;

[0056] Input the first conveying assembly for adjustment, the control system sends a command to the first driving assembly, the first driving assembly drives the movable part corresponding to the first conveying assembly to rotate, the movable part corresponding to the first conveying assembly is aligned with the fixed part through rotation, and the material begins to move toward the movable part under the action of gravity, preparing for subsequent input to the first transport platform;

[0057] Material input, the control system controls the chain transmission component to start, the second drive component drives the sprocket to rotate, drives the chain to move, and drives the first transport platform to move from bottom to top toward the material. Since the multiple movable rods and the multiple bearing rods are staggered, the movable bearing rods will pass through the gaps between the movable rods, and take over the materials from the movable rods, so as to realize the input of materials onto the first transport platform;

[0058] Adjustment of the output first conveying assembly: when the first transport platform reaches the target floor, the control system controls the movable part of the first conveying assembly for output on the target floor to rotate so that it is flush with the fixed part. In this way, preparations are made for the output of materials from the first transport platform to the first conveying assembly on that floor;

[0059] For material output, the chain transmission assembly drives the first transport platform to move downward from top to bottom toward the first conveying assembly for output on the target floor. Similarly, since the multiple movable rods and the multiple load-bearing rods are staggered, the movable load-bearing rods pass through the gaps between the movable rods, transferring the materials from the load-bearing rods to the movable rods, and then to the rollers of the fixed part through the movable rods, and finally the materials are output to the first conveying assembly for output on the target floor.

[0060] The above-mentioned vertical material transportation method provides a complete set of solutions for vertical material transportation, with clear operation processes, facilitating implementation and management. Whether in the production workshop of a factory or in the logistics distribution of a warehouse, materials can be efficiently transported according to this method; it makes full use of the structural characteristics of the transportation device to achieve efficient and accurate material transportation. Through precise control systems and reasonable operation processes, errors and delays during material transportation are reduced, logistics efficiency is improved, and labor costs are lowered.

[0061] The technical solution of this application is achieved by setting a chain drive assembly, a first transportation platform, a first conveying assembly, and a control system. The chain drive assembly is arranged between multiple floors and is used to drive the first transportation platform to move. The first transportation platform is used to place materials. The first conveying assembly is arranged on both sides of the chain drive assembly corresponding to each floor and is used to input or output materials to or from the first transportation platform. The control system is used to control the operation of the chain drive assembly. The first transportation platform includes a carrier, and the carrier is rotatably installed on the chain drive assembly. On the side of the carrier facing the first conveying assembly, a plurality of carrier rods are arranged, and the plurality of carrier rods jointly carry materials. The first conveying assembly includes a fixed part and a movable part. The fixed part is fixedly installed on the corresponding floor, and the movable part is rotatably connected to the fixed part. The movable part includes a movable frame, and on the side of the movable frame facing the first transportation platform, a plurality of movable rods are arranged, and the plurality of movable rods and the plurality of carrier rods are staggered. After the control system is started, it controls the operation of the chain drive assembly to drive the first transportation platform to move between multiple floors. When the first transportation platform moves to a specific floor, the first conveying assembly corresponding to this floor can, according to actual needs, input or output materials to or from the first transportation platform. If this floor is the starting floor of the materials, the first conveying assembly will convey the materials onto the first transportation platform. If this floor is the target floor of the materials, the first conveying assembly will receive the materials from the first transportation platform. When materials are input or output, due to the staggered distribution of the plurality of movable rods and the plurality of carrier rods, the moving carrier rods will pass through the gaps between the movable rods, thereby realizing the input or output of materials. In specific use, the chain drive assembly can always drive the first transportation platform to move. Only by unfolding the movable parts of the input first conveying assembly on the starting floor and the output first conveying assembly on the target floor, the input first conveying assembly on the starting floor can continuously convey materials to the movable part, and the moving first transportation platform will continuously convey the materials on the starting floor to the target floor. This design, combined with the use of the control system, can achieve automated transportation of materials between different floors, without the need for workers to follow the operation throughout the process, realizing fast vertical transportation of materials between multiple floors, greatly improving transportation efficiency and convenience.
