Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation equipment maintenance, in particular to a three-dimensional axle transmission warehouse. Background Art

[0002] Railway vehicles are important means of transportation, and the quality of their maintenance is directly related to driving safety. As an important part of the vehicle running parts, wheelsets bear the dual responsibilities of ensuring driving safety and serving transportation. With the increase in maintenance tasks and the extension of maintenance cycles, the condition of the wheelsets at each maintenance is getting worse and worse. Therefore, it is necessary to disassemble the wheelsets and reassemble the axles and wheels of the wheelsets to ensure the safety and stability of the wheelsets within two maintenance cycles. The main reason for the disassembly and maintenance of wheelsets is that the wheels are worn beyond the limit and need to be replaced. As the carrier connecting the wheels and bearings on both sides, the axles have higher maintenance requirements. Therefore, in the disassembly and maintenance of wheelsets, the axles are mainly processed, and the axles and bearings are matched based on the axle size.

[0003] In recent years, in order to improve the production capacity and automation level of wheelset axle machining production lines, most production lines have been upgraded and renovated, using CNC lathes and grinders to replace manual measurement and setting of processing parameters, and using truss manipulators to complete the axle transfer and loading and unloading between processing steps. However, there are still many shortcomings and limitations, which are specifically manifested in the following aspects:

[0004] (1) The truss robot track usually spans 4-5 lathes, each of which is arranged in parallel. On average, each truss robot is responsible for loading and unloading and axle transfer of 2 lathes. The lathe in the middle process needs to be loaded by the first truss robot and unloaded by the second truss robot. The two truss robots may conflict with each other due to the simultaneous completion of operations at the front and rear stations. At this time, one of the truss robots needs to wait for the other truss robot to complete the operation before it can start the operation. This will affect the rhythm of the entire production line and affect production efficiency. In addition, when the production rhythms of the front and rear lathes are different, more axles will be accumulated at the unloading position of the lathe with faster production efficiency, and an overhead crane will need to intervene to complete the transfer.

[0005] (2) In order to save production space and ensure the production rhythm of the truss manipulator in the production layout, the distance between lathes is small, and the number of axles stored between each lathe is limited, which requires frequent transfer of the truss manipulator, resulting in high production pressure.

[0006] (3) The placement order of the processing lathes varies according to different maintenance processes. Generally, they are placed according to the process of the blank shaft (three processes). The processing process of the old shaft (refurbishment) is two processes. Therefore, the old shaft needs to quickly pass through one of the processes. Due to the short span of the truss robot, the front and rear robots will cross their operations, and the old shaft cannot be quickly passed by a single robot.

[0007] (4) The materials in the production line are stored separately from the materials to be processed. When new materials enter the production line, they need to be transferred twice. The first time is from outside the warehouse to the warehouse, and the second time is to enter the production line.

[0008] Therefore, it is necessary to study an axle three-dimensional transmission library to solve the above problems or alleviate the impact of the above problems. Utility Model Content

DETAILED DESCRIPTION

[0032] The utility model will be further described below in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, the axle stereoscopic transmission warehouse of the utility model comprises at least two rows of shelves 1 for storing axles 9, a conveying channel 2 is formed on the inner side of the two rows of shelves 1, and multiple machining lathes 3 are arranged on the outer side of the two rows of shelves 1, and the multiple machining lathes 3 are used to process the axles 9 in different processes;

[0034] Among them, a stacker 4 is used on the conveying channel 2 to transport the axle 9, and truss robots 5 for loading and unloading are provided on both sides of the machining lathe 3. A loading and unloading conveyor line 6 is provided between the machining lathe 3 and the conveying channel 2. The loading and unloading conveyor line 6 is used for transmission between the stacker 4 and the truss robot 5.

[0035] Specifically, the axle three-dimensional transmission warehouse is provided with two rows of shelves 1 along the circulation direction of entering and exiting the warehouse, and between the two rows of shelves 1 is a conveying channel 2 for the transfer and circulation of axles 9. A row of machining lathes 3 are provided on the opposite outer sides of the two rows of shelves 1 along the circulation direction of entering and exiting the warehouse, and each row of machining lathes 3 includes a plurality of machining lathes 3 for performing different processes on the axles 9. Truss manipulators 5 for loading and unloading are provided on both sides of the machining lathes 3, and a loading and unloading conveying line 6 is provided between each machining lathe 3 and the conveying channel 2, and the position of the loading and unloading conveying line 6 corresponds to the position of the machining lathe 3.

[0036] During specific operations, the axle 9 can be temporarily stored on the shelf 1 near the machining lathe 3 through the stacker 4. When the machining lathe 3 is idle, the axle 9 can be transferred to the loading and unloading conveyor line 6 through the stacker 4. The loading and unloading conveyor line 6 can transfer the axle 9 from one end close to the conveying channel 2 to the other end close to the machining lathe 3, and then the truss manipulators 5 on both sides of the machining lathe 3 can load the axle 9 to be processed to the machining lathe 3, and at the same time unload the processed axle 9 to the loading and unloading conveyor line 6. The loading and unloading conveyor line 6 then transfers the processed axle 9 to one end close to the conveying channel 2 and hands it over to the stacker 4 for transfer to the shelf 1 near the machining lathe 3 of the next process, thereby realizing the transfer or loading and unloading of the axle 9.

[0037] In general, the axle three-dimensional transfer warehouse uses the stacker 4 to transfer the axle 9 between the shelf 1 and the machining lathes 3 of different processes, replacing the truss manipulator 5 to transfer the axle 9. The loading and unloading conveyor line 6 is connected between the stacker 4 and the truss manipulator 5, which can reduce the time for the truss manipulator 5 to perform loading and unloading operations and ensure the smooth operation of the production line. In this way, the loading and unloading and transportation of the axle 9 can be carried out simultaneously, which can improve the work efficiency of the automatic loading and unloading of the axle 9, and is also suitable for the storage and circulation of other materials in multiple maintenance processes.

[0038] In an example, Figure 1 and Figure 2 As shown, the loading and unloading conveyor line 6 includes a loading conveyor line 61 and a unloading conveyor line 62 which are arranged side by side. The loading conveyor line 61 and the unloading conveyor line 62 have the same structure and opposite transmission directions.

[0039] Specifically, the function of the loading conveyor line 61 is to assist the truss manipulator 5 in loading operations, and its transportation direction is from one end close to the conveying channel 2 to one end close to the machining lathe 3; the unloading conveyor line 62 is to assist the truss manipulator 5 in unloading operations, and its transportation direction is from one end close to the machining lathe 3 to one end close to the conveying channel 2.

[0040] In an example, Figure 2 and Figure 3 As shown, the loading conveyor line 61 and the unloading conveyor line 62 both include a driving sprocket 601 and a driven sprocket 602 , and a matching conveying chain 603 is mounted on the driving sprocket 601 and the driven sprocket 602 . The conveying chain 603 can rotate with the driving sprocket 601 and the driven sprocket 602 to realize the transmission of the axle 9 .

[0041] Specifically, the loading conveyor line 61 and the unloading conveyor line 62 have the same structure, both including a driving sprocket 601, a driven sprocket 602 and a conveying chain 603. The conveying chain 603 matches the driving sprocket 601 and the driven sprocket 602. The driving sprocket 601 rotates under the external driving force, thereby driving the conveying chain 603, and then the conveying chain 603 drives the driven sprocket 602 to rotate. The conveying chain 603 is an annular structure and can rotate with the driving sprocket 601 and the driven sprocket 602 to form a cycle, so as to realize the transmission of the axle 9.

[0042] In an example, Figure 3 and Figure 4 As shown, the driving sprocket 601 is driven by the motor 604 and the reducer 605. Both the loading conveyor line 61 and the unloading conveyor line 62 are equipped with a driving structure in which the motor 604 and the reducer 605 cooperate, and the output end of the motor 604 is connected to the input end of the reducer 605.

[0043] In an example, Figure 4 As shown, the output end of the reducer 605 is connected to a driving gear 606, and a driven gear 607 is fixedly connected to one side of the driving sprocket 601, and the driven gear 607 is meshed with the driving gear 606. The reducer 605 transmits power to the driving sprocket 601 through the meshing of the driving gear 606 and the driven gear 607. It should be noted that the driven gear 607 can be fixed together with the driving sprocket 601 on the transmission shaft 608 to achieve fixed connection.

[0044] In an example, Figure 2 and Figure 3 As shown, the conveyor chain 603 is provided with a plurality of buffer positions 609 distributed along the transmission direction, and the buffer positions 609 are used to position and place the axles 9. Each buffer position 609 can position and place an axle 9, so that the conveyor chain 603 can cache a plurality of axles 9, thereby ensuring the storage amount of the axles 9. The number of buffer positions 609 can be set to 3 to 10, which can be set according to actual conditions.

[0045] In one example, the buffer position 609 is a concave structure, which can support and limit the axle 9. Specifically, a plurality of protrusions are provided on the outer side of the conveyor chain 603, and two adjacent protrusions form a concave limiting support structure, which can support the lower end of the axle 9 and position the axle 9.

[0046] In one example, the shelf 1 is a multi-layer structure, and the shelf 1 can store multiple axles 9 in the vertical direction. The shelf 1 is a three-dimensional multi-layer structure, that is, the shelf 1 is divided into multiple layers in the vertical direction, so as to increase the number of axles 9 that can be stored in the shelf 1. Furthermore, each layer of the shelf 1 can be provided with multiple placement positions for storing axles 9.

[0047] In an example, Figure 2 and Figure 3 As shown, the loading and unloading conveyor line 6 is installed on one layer of the shelf 1 through a frame 610.

[0048] Specifically, the loading conveyor line 61 and the unloading conveyor line 62 are respectively installed on the same layer of two adjacent shelves 1, and the installation height of the loading conveyor line 61 and the unloading conveyor line 62 should be convenient for receiving the stacker 4 and docking with the truss manipulator 5. It should be noted that the loading conveyor line 61 and the unloading conveyor line 62 can also directly occupy a shelf 1 position respectively, but relatively speaking, when the loading conveyor line 61 and the unloading conveyor line 62 are set on one layer of the shelf 1, the other layers of the shelf 1 can also be used to store axles 9, and the number of axles 9 that can be stored is greater.

[0049] It should also be noted that, in order to further ensure the number of axles 9 that can be stored in the three-dimensional axle transfer warehouse, storage positions can be added between adjacent machining lathes 3, or storage positions can be added below the truss manipulator 5 and above the machining lathe 3.

[0050] In an example, Figure 1 As shown, the axle three-dimensional transmission warehouse also includes an entry position 7 and an exit position 8, which are respectively located at the two ends of the conveying channel 2. The entry position 7 and the exit position 8 are the entrances and exits of the axle 9 in and out of the transmission warehouse. The axle 9 enters from the entry position 7 and can be received by the stacker 4 and stored on the shelf 1. After the axle 9 completes all processing procedures, the stacker 4 can move the axle 9 out to the exit position 8. It should be noted that both the entry position 7 and the exit position 8 can be provided with a conveyor belt for transmission and transportation.

[0051] In order to better understand the present invention, the working process of the three-dimensional axle transmission warehouse is further described in conjunction with the accompanying drawings.

[0052] First, the axle 9 enters from the storage position 7, and the stacker 4 completes the material receiving and stores the axle 9 on the nearby shelf 1. When the machining lathe 3 is idle, the stacker 4 takes the axle 9 from the shelf 1 and places it on the loading conveyor line 61. The axle 9 is transferred from the end close to the conveying channel 2 to the end close to the machining lathe 3. Finally, the loading truss manipulator 5 completes the loading of the machining lathe 3; the axle 9 that has been machined is unloaded by the truss manipulator 5, and the axle 9 is grabbed and placed on the unloading conveyor line 62. The axle 9 is transferred from the end close to the machining lathe 3 to the end close to the conveying channel 2 and enters the working range of the stacker 4. The stacker 4 completes the transfer of the axle 9 and places the axle 9 on the shelf 1 near the next process. When the machining lathe 3 of the next process is idle, repeat the above steps.

[0053] Take the blank shaft as an example: the blank shaft enters through the storage position 7 at one end and is stored by the stacker 4 on the shelf 1 close to the first working procedure. When the axle 9 needs to be processed in the first working procedure, the stacker 4 removes the axle 9 and places it on the loading conveyor line 61. The axle 9 that has completed the first processing procedure enters the conveying channel 2 again through the unloading conveyor line 62. The stacker 4 then places the axle 9 on the shelf 1 close to the second working procedure, and completes all processing procedures in sequence. At the same time, the storage position of the axle 9 is also moved from the initial position to a position close to the storage position 8. In this way, the three-dimensional axle transmission warehouse can ensure the storage quantity of the axle 9 while completing the transfer of the axle 9.

[0054] In summary, the beneficial effects of the axle stereoscopic transmission library of the utility model include but are not limited to the following:

[0055] (1) The axle three-dimensional transmission warehouse of the utility model uses a stacker and a truss manipulator to complete the transfer and loading and unloading of axles respectively, so that the operations can be completed simultaneously and there will be no overlap in production operations.

[0057] (3) The three-dimensional axle transfer warehouse of the utility model can store new materials (axles) at the same time, making more rational use of space and reducing the number of times new materials are transferred.

[0058] (4) The axle three-dimensional transmission warehouse of the utility model realizes the functional expansion of the three-dimensional warehouse by combining the existing three-dimensional warehouse with the loading and unloading conveyor line, that is, the process flow of materials (axles) in the warehouse is increased; the two ends of the conveying channel serve as the total input and total output of materials, and the loading and unloading conveyor lines are installed on both sides of the conveying channel for the diversion of materials between different processes; the function of the stacker is not just material storage and expenditure, but more of the material transfer between different processes.

[0059] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
