Description

Technical Field

[0001] This application relates to the field of transportation equipment technology, and in particular to transshipment equipment. Background Technology

[0002] As a rail transit vehicle that relies on the power grid for electricity and is driven by electric motors, electric locomotives require regular maintenance and repair of their core components, such as IGBT (Insulated Gate Bipolar Transistor) modules, after long-term operation. During maintenance, workers must remove the IGBT modules from the locomotive's control compartment and transfer them to the maintenance platform.

[0003] In related technologies, disassembled IGBT modules are mostly handled manually or transported by simple flatbed trucks. However, due to the compact internal space of the electric locomotive control compartment and the narrow transport space, traditional transport tools are difficult to move flexibly, resulting in poor transport operation convenience, low transport efficiency, and affecting maintenance progress.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] See Figures 1 to 3 The diagram shows a schematic representation of a transfer device 10 according to an embodiment of this application. The transfer device 10 provided in this embodiment includes a mounting base 100, a supporting mechanism 200, and a traveling mechanism 300. This transfer device 10 can transfer the object 20 to be transferred, and the transfer operation is convenient and efficient. For example, the object 20 to be transferred can be an IGBT module, meaning the transfer device 10 can be used to transfer IGBT modules that need to be repaired.

[0037] Specifically, the mounting base 100 serves as a basic support structure, providing a support position for the installation of other structures such as the load-bearing mechanism 200, ensuring the stability of these other structures during operation. For example, the mounting base 100 can be configured as a roughly rectangular metal base, with a maximum length * width of 1200mm * 400mm.

[0038] The support mechanism 200 is connected to the mounting base 100 and is used to support the object 20 to be transferred. Exemplarily, the top surface of the support mechanism 200 has a support platform on which multiple manual elbow clamps can be configured for securing the object 20 to be transferred. The support platform may also have slots to adjust the installation position of the elbow clamps. Furthermore, a soft silicone sheet may be applied to the surface of the support platform to increase the coefficient of friction between the support platform and the object 20 to be transferred, while protecting the object 20 from impact damage.

[0039] The traveling mechanism 300 includes a connecting assembly 310 and a first roller assembly 320, the first roller assembly 320 being connected to the mounting base 100 via the connecting assembly 310. The first roller assembly 320 includes a first traveling roller 321 and a first roller shaft component 322. The first traveling roller 321 is circular and rotatably connected to the connecting assembly 310, allowing it to rotate along its own axis. Figure 1 As shown, the transfer device 10 can move along its length direction via the first traveling roller 321. A first mounting groove 323 is provided on the outer periphery of the first traveling roller 321, and a first roller component 322 is disposed within the first mounting groove 323 and rotatably connected to the first traveling roller 321. Exemplarily, the first roller component 322 is configured as a spindle-shaped structure, thicker in the middle and narrower at both ends, and the first roller component 322 can rotate freely along its own axial direction within the first mounting groove 323. Figure 1 As shown, the first roller component 322 enables the transfer device 10 to move along its width direction.

[0040] Through the above structural design, the transfer device 10 of this embodiment, through the cooperation of the first traveling roller 321 and the first roller component 322, can move the transfer device 10 along its length direction via the first traveling roller 321, and also move the transfer device 10 along its width direction via the first roller component 322. Therefore, during the transfer process, the transfer device 10 can flexibly change the transfer direction, thereby providing convenience for transfer operations and improving transfer efficiency. When used to transfer IGBT modules, this transfer device 10 can provide stable lifting and flexible transfer of IGBT modules in the confined control compartment of an electric locomotive, reducing the labor intensity of maintenance work and providing great convenience for the maintenance of IGBT modules.

[0041] See Figure 1 and Figure 3As shown, in some embodiments, the traveling mechanism 300 further includes a second roller assembly 330, which includes a second traveling roller 331 and a second roller component 332. The second traveling roller 331 is configured to have the same structure as the first traveling roller 321, and the second traveling roller 331 and the first traveling roller 321 are fixedly connected by a shaft passing through their centers, allowing the second traveling roller 331 to rotate relative to the connecting assembly 310 with the first traveling roller 321. A second mounting groove 333 is provided on the outer periphery of the second traveling roller 331, and the second roller component 332 is configured to have the same structure as the first roller component 322. The second roller component 332 is disposed in the second mounting groove 333 and rotatably connected to the second traveling roller 331, allowing the second roller component 332 to rotate freely within the second mounting groove 333. Through the cooperation of the second roller assembly 330 and the first roller assembly 320, the stability of the transfer equipment 10 can be enhanced, enabling the transfer equipment 10 to pass through narrow channels more easily and improving transfer efficiency.

[0042] Further, see Figure 1 and Figure 3 As shown, the first roller assembly 320 includes six first roller components 322, and the first traveling roller 321 has six first mounting slots 323 corresponding one-to-one with the six first roller components 322 along its circumference. The six first mounting slots 323 are evenly distributed along the circumference of the first traveling roller 321. The second roller assembly 330 includes six second roller components 332, and the second traveling roller 331 has six second mounting slots 333 corresponding one-to-one with the six second roller components 332 along its circumference. The six second mounting slots 333 and the six first mounting slots 323 are alternately distributed along the circumference of the second traveling roller 331, that is, in the circumference of the first traveling roller 321 and the second traveling roller 331, any one first mounting slot 323 is located between two adjacent second mounting slots 333, and any one second mounting slot 333 is located between two adjacent first mounting slots 323. Therefore, when the first traveling roller 321 and the second traveling roller 331 are connected as a whole and roll, their motion trajectories compensate for each other, so that the rotation trajectory of the first roller assembly 320 and the second roller assembly 330 is approximately circular, which can ensure the stability of the transfer device 10 during movement.

[0043] It should be understood that in other alternative embodiments, the number of the first roller component 322, the first mounting groove 323, the second roller component 332, and the second mounting groove 333 is not limited to the above example. For example, the number of the first roller component 322, the first mounting groove 323, the second roller component 332, and the second mounting groove 333 can be three, four, five, seven, eight, etc.

[0044] Furthermore, the first traveling roller 321 and the second traveling roller 331 are coaxially arranged and have the same diameter, ensuring that they remain synchronized during rotation and avoiding rotational deviations caused by different diameters, resulting in smoother transport. In addition, the axial direction of the first roller component 322 and the axial direction of the second roller component 332 are perpendicular to the axial direction of the first traveling roller 321, enabling the first roller component 322 and the second roller component 332 to drive the transport device 10 to move in the same direction, for example, enabling the first roller component 322 and the second roller component 332 to drive the transport device 10 to move in the width direction, further ensuring smooth transport.

[0045] See Figure 2 As shown, in some embodiments, the connecting assembly 310 includes a connecting shaft 311, a planetary carrier 312, a limiting frame 313, and a bearing 314. The limiting frame 313 is disposed at the bottom of the mounting base 100, and the connecting shaft 311 is sleeved inside the limiting frame 313. The connecting shaft 311 is fixedly connected to the limiting frame 313 and the mounting base 100. The planetary carrier 312 is sleeved at both ends of the connecting shaft 311, and the planetary carrier 312 is rotatably connected to the connecting shaft 311 through the bearing 314. The outer circumference of the planetary carrier 312 is rotatably provided with three equidistantly distributed first roller assemblies 320 and three equidistantly distributed second roller assemblies 330. Exemplarily, the connecting assembly 310 may also include a drive device, such as a motor, for driving the planetary carrier 312 to rotate. When the planetary carrier 312 rotates, the three first roller assemblies 320 and the three second roller assemblies 330 rotate around the connecting shaft 311, thereby enabling movement across obstacles, allowing the transfer equipment 10 to more easily traverse various complex terrains and improving transfer efficiency.

[0046] Of course, in other alternative embodiments, the number of the first roller assembly 320 and the second roller assembly 330 is not limited to the above example. For example, the number of the first roller assembly 320 and the second roller assembly 330 can be four, five, six, etc.

[0047] See Figures 1 to 3As shown, in some embodiments, the transfer device 10 further includes a lifting mechanism 400, which is connected between the mounting base 100 and the carrying mechanism 200. The lifting mechanism 400 enables the lifting movement of the carrying mechanism 200. Specifically, the lifting mechanism 400 includes a lifting component 410 and a drive component 420. The lifting component 410 is connected to both the mounting base 100 and the carrying mechanism 200, and the drive component 420 is mounted on the mounting base 100 and drivenly connected to the lifting component 410. Both ends of the lifting component 410 are connected to the mounting base 100 and the carrying mechanism 200, respectively. The drive component 420 is mounted on the mounting base 100 and drivenly connected to the lifting component 410. The drive component 420 provides power to the lifting component 410, enabling the lifting mechanism 400 to automatically lift and lower the carrying mechanism 200, and to precisely control the lifting height of the carrying mechanism 200. Therefore, the carrying mechanism 200 can adjust its height as needed, facilitating the loading and unloading of the items 20 to be transferred on maintenance platforms at different heights. For example, when the object to be transferred 20 needs to be loaded onto a higher maintenance platform, the lifting mechanism 400 can raise the carrying mechanism 200 to a suitable height, which helps to reduce the handling intensity of the staff and improve the efficiency of the maintenance work.

[0048] Further, see Figure 1 and Figure 2 As shown, the lifting assembly 410 includes a guide rail 411, a fixed base 412, a movable base 413, and a lifting scissor fork 414. The guide rail 411 and the fixed base 412 are respectively connected to the mounting base 100, and the movable base 413 is slidably connected to the guide rail 411. The top of the lifting scissor fork 414 is movably configured to hold the load-bearing mechanism 200 of the object to be transferred 20. The bottom of the lifting scissor fork 414 is hinged to the fixed base 412 and the movable base 413, forming a telescopic structure to drive the load-bearing mechanism 200 to rise and fall. The guide rail 411 provides guidance for the sliding of the movable base 413, ensuring that the movable base 413 remains stable during lifting and falling, preventing swaying.

[0049] Optionally, the lifting assembly 410 includes two parallel guide rails 411. Correspondingly, two fixed seats 412 and two movable seats 413 are provided, with each guide rail 411 connected to a corresponding movable seat 413. The lifting scissor fork 414 adopts a two-stage lifting structure and is hinged to the movable seats 413 on the two guide rails 411, giving the lifting scissor fork 414 good lifting anti-sway stiffness, thereby giving the lifting mechanism 400 high stability and reliability. For example, when used for transporting IGBT modules, the lifting scissor fork 414 can be set to a minimum retracted height of 800mm, a designed rated load capacity of 150kg, and the overall weight of the transport device 10 is approximately 225kg.

[0050] Further, see Figure 2As shown, the drive assembly 420 includes a fixing member 421 and a drive member 422. The fixing member 421 is located at the end of the mounting base 100 away from the movable seat 413, and the drive member 422 is connected to the fixing member 421. Exemplarily, the fixing member 421 is a plate-like structure, the drive member 422 is an electric push rod, and a crossbeam 416 is provided between the two movable seats 413. The output end of the drive member 422 is connected to the middle of the crossbeam 416. Thus, by driving the crossbeam 416 to move via the drive member 422, the movable seat 413 can move along the guide rail 411, which in turn drives the lifting scissor fork 414 to extend and retract, thereby realizing the lifting and lowering of the carrying mechanism 200. This allows for flexible control of the height of the carrying mechanism 200, providing stable support for IGBT modules of different heights and greatly facilitating transport operations. Furthermore, the mounting base 100 is equipped with a switch for controlling the drive member 422 and a battery for powering the drive member 422, ensuring the normal operation of the drive member 422.

[0051] Optionally, the lifting assembly 410 also includes a limiting slider 415, which is connected to the movable seat 413. The guide rail 411 has a guide groove, and the limiting slider 415 is disposed in the guide groove and slidably connected to the guide rail 411. Specifically, the limiting slider 415 can be configured to fit the shape of the guide groove, so that the limiting slider 415 engages with the guide groove of the guide rail 411 with almost zero clearance, and the limiting slider 415 can slide along the guide groove. Thus, the guide rail 411 and the limiting slider 415 cooperate to guide the movable seat 413, further limiting the movement direction of the movable seat 413, ensuring that the movable seat 413 will not deviate during sliding and lifting, effectively eliminating lateral disturbances of the lifting scissor lift 414, and improving the stability of the lifting scissor lift 414.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
