Description

Technical Field

[0001] This utility model relates to the field of rail vehicle manufacturing technology, and in particular to a ground transfer device for rail vehicle electrical cabinets. Background Technology

[0002] In the production of rail vehicles, the manufacturing process for electrical cabinets typically involves first transferring the cabinet frame to the assembly line. After the assembly and wiring of the electrical cabinet are completed at the assembly line, it is then transferred to the testing area for safety testing. Currently, many transfer processes in the electrical cabinet production workflow are mainly carried out manually by lifting or transporting the cabinets onto flatbed trolleys.

[0003] When moving the electrical cabinet manually, the heavy weight makes it physically demanding and cumbersome to move or reposition it. Accidents during transport can damage the cabinet and even cause injury. While using a flatbed cart allows for movement, it's inconvenient to assemble and wire the cabinet on it. The frame must be moved to the workstation for assembly and wiring, and then moved back to the cart. Furthermore, the lack of fixed points on the cart and the cabinet's height make it unstable and prone to tipping over. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a ground transfer device for rail vehicle electrical cabinets that integrates multiple functions such as support, ground transfer, and assembly of electrical cabinet assembly processes, is highly versatile, easy to use, and provides stable and reliable support.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A ground transfer device for an electrical cabinet of a rail vehicle includes two independent, elongated movable bases. Each movable base consists of a first section and a second section that can extend and retract relative to each other. Movable wheels are installed below the first section and the second section respectively. Fixing structures for fixing the electrical cabinet are respectively provided on the support surfaces of the first section and the second section. A locking mechanism for locking at any extension length is provided between the first section and the second section.

[0007] Furthermore, the support surfaces at the top of the first and second segments are at the same height and form a continuous support plane when stretched to the minimum length.

[0008] Furthermore, the first segment and the second segment are respectively composed of an upper support part and a lower telescopic part. The telescopic part of the first segment is nested inside the telescopic part of the second segment to achieve relative telescopic expansion and contraction. The top surface of the support part is a support surface.

[0009] Furthermore, the support portion of both the first and second segments consists of a support base and a layer of adhesive sheet pasted onto the upper surface of the support base.

[0010] Furthermore, the support portion is welded to the telescopic portion below.

[0011] Furthermore, the length of the support portion of the first segment is shorter than that of the telescopic portion and is aligned and installed at the end of the telescopic portion away from the second segment; the length of the support portion of the second segment is longer than or equal to that of the telescopic portion, and the telescopic portion is aligned and installed at the end of the support portion facing the first segment.

[0012] Furthermore, the telescopic part is a box-shaped structure with an open bottom. The movable wheel on the first section is installed inside the telescopic part, and the movable wheel on the second section is installed below the support or inside the telescopic part.

[0013] Furthermore, the locking mechanism is located on the side of the telescopic part facing the outside of the electrical cabinet.

[0014] Furthermore, the locking mechanism includes at least two mounting holes arranged along the length direction on the side of the first telescopic section and an elongated oval hole extending along the length direction on the side of the second telescopic section, wherein the mounting holes and the elongated oval hole are fixed by fasteners.

[0015] Furthermore, the fixing structure includes a plurality of fixing holes or slots arranged along the length direction on the support surface, and the electrical cabinet is fixedly connected to the fixing holes or slots at the corresponding positions by fasteners or buckles.

[0016] In summary, the ground transfer device for electrical cabinets of rail vehicles provided by this utility model has the following advantages compared with the prior art:

[0033] like Figures 1 to 3 As shown, this utility model provides a ground transfer device for an electrical cabinet of a rail vehicle, comprising two independent movable bases 1, with the bottom of the electrical cabinet 2 supported on the two movable bases 1. Both movable bases 1 are elongated and consist of a first segment 11 and a second segment 12 that are retractable relative to each other. Moving wheels 3 are respectively installed below the first segment 11 and the second segment 12. Fixing structures 5 for fixing to the electrical cabinet 2 are respectively provided on the supporting surfaces of the first segment 11 and the second segment 12. A locking mechanism 6 for locking at any retractable length is provided between the first segment 11 and the second segment 12.

[0034] In this embodiment, two relatively independent movable bases 1 support the electrical cabinet 2. The support spacing between the two movable bases 1 can be flexibly adjusted according to the size of the electrical cabinet 2, making the device applicable to electrical cabinets 2 of any size and specifications, with strong versatility, and ensuring the stability and reliability of the support. Simultaneously, operators can directly install the frame of the electrical cabinet 2 onto the movable base 1. The electrical cabinet frame is relatively lightweight, making transportation easier. Assembly and wiring operations for the electrical cabinet 2 can also be performed directly on the movable base 1 until the electrical cabinet 2 is completed, at which point the movable base 1 is disassembled. This device integrates multiple functions such as support, ground handling, and electrical cabinet assembly, making it convenient to use. When assembly and wiring operations are required, there is no need to move the frame of the electrical cabinet 2 to a fixed position, improving the efficiency of electrical cabinet assembly and reducing labor intensity. Furthermore, the electrical cabinet 2 can be fixed to the movable base 1 via a fixing structure 5, ensuring the stability and high load-bearing capacity of the electrical cabinet 2 during movement, assembly, and wiring, preventing tipping accidents and ensuring safe operation.

[0035] In this embodiment, the movable wheel 3 installed below the first section 11 is a directional wheel, and the movable wheel 3 installed below the second section 12 is a universal wheel with a braking device 9. This allows the movable base 1 to be moved 360° flexibly by pushing the electrical cabinet 2, and the movable base 1 can be stabilized at a specific work position by the braking device without damaging the ground. It also helps to improve the impact resistance stability when fixed, which is especially suitable for heavy-duty scenarios. In addition, to ensure the stability during support and movement, two directional wheels and two universal wheels with braking devices are installed. Preferably, the load-bearing capacity of a single movable wheel 3 is greater than 80kg, and more preferably, movable wheels 3 with a double bearing structure are used to reduce rotational resistance.

[0036] In this embodiment, the first segment 11 and the second segment 12 are respectively composed of an upper support portion and a lower telescopic portion. Specifically, the first segment 11 has an upper support portion 111 and a lower telescopic portion 112, and the second segment 12 has an upper support portion 121 and a lower telescopic portion 122. The telescopic portion 112 of the first segment 11 is nested within the telescopic portion 122 of the second segment 12 to achieve relative telescopic movement. The top surfaces of the support portions 111 of the first segment 11 and 121 of the second segment 12 are both support surfaces 4. In this embodiment, preferably, the total length of the movable base 1 is freely telescopic between 400mm and 800mm, and the total height of the movable base 1 does not exceed 80mm, more preferably 70mm.

[0037] The first segment 11's support portion 111 consists of a support base 1111 and a layer of adhesive board 1112 adhered to the upper surface of the support base 1111. The second segment 12's support portion 121 consists of a support base 1211 and a layer of adhesive board 1212 adhered to the upper surface of the support base 1211. This design prevents damage when the electrical cabinet 2 comes into contact with the movable base 1. Furthermore, both the support base 1111 and the support base 1211 are rectangular in shape and welded to the telescopic portions 112 and 122, which further enhances their support strength.

[0038] In this embodiment, it is further preferred that the length of the support portion 111 of the first segment 11 is shorter than that of the telescopic portion 112, and one end of the support portion 111 is aligned with one end of the telescopic portion 112 (the end away from the second segment 12). The length of the support portion 121 of the second segment 12 is longer than or equal to that of the telescopic portion 122, and one end of the telescopic portion 122 is aligned with one end of the support portion 121 (the end facing the first segment 11). This ensures the required telescopic length between the first segment 11 and the second segment 12, and also ensures that the support surfaces 4 of the first segment 11 and the second segment 12 are at the same height and form a continuous support plane when telescopically extended to the minimum length. This not only increases the applicability of the mobile base 1, but also provides multiple support points for the bottom of the complex electrical cabinet 2 structure, thereby further improving the stability and reliability of the mobile base 1 in supporting the electrical cabinet 2.

[0039] In this embodiment, to further enhance the load-bearing capacity, both the support part and the telescopic part are made of carbon steel. The support part 111 and the support part 121 are long strip-shaped solid blocks, and the telescopic parts 112 and the telescopic parts 122 are box-shaped structures with open bottoms. Multiple reinforcing ribs are provided inside the box-shaped structure to further improve the load-bearing capacity, so that the overall load of the mobile base 1 is not less than 100Kg.

[0040] Both the telescopic sections 112 and 122 are welded together from a top plate, two side plates, and one end plate (not shown in the figure). The movable wheels 3 on the first section 11 are installed inside the telescopic section 112. The box-shaped telescopic section 112 protects the movable wheels 3 and also helps to lower the height of the movable base 2. If the length of the support section 121 of the second section 12 is longer than the lower telescopic section 122, the movable wheels 3 on the second section 12 are installed below the tail end of the movable base 1 of the support section 121, making it convenient for the operator to operate the foot brake device. Figures 1 to 3As shown, the length of the support portion 121 of the second section 12 is equal to the length of the telescopic portion 122. However, to facilitate the operator's foot operation of the brake device, the telescopic portion 122 is divided into two sections with different heights. Near the end of the movable wheel 3, the height of the telescopic portion 122 is reduced. This not only improves the load-bearing capacity of the second section 12 but also facilitates the operator's foot operation of the brake device. The movable wheel 3 is fixed to the corresponding telescopic portion 112 and support portion 121 by the mounting plate 7 and multiple screws 8.

[0041] In this embodiment, the fixing structure 5 includes a plurality of fixing holes 51 arranged along the length direction on the support surface 4. For example, three fixing holes 51 are arranged on the support portion 111 of the first segment 11, and seven fixing holes 51 are arranged on the support portion 121 of the second segment 12. The fixing holes 51 include through holes penetrating the rubber plate 1112 or the rubber plate 1212 and corresponding internal threaded holes provided on the support base 1111 or the support base 1211. The electrical cabinet 2 is fixedly connected to the fixing holes 51 at the corresponding positions by fasteners. Here, the fasteners are preferably handle screws 52. The handle screws 52 pass downward through the through holes of the rubber plate 1112 or the rubber plate 1212 and are fixedly connected to the internal threaded holes on the support base 1111 or the support base 1211 below. This makes it convenient to fix and connect with electrical cabinets 2 of different specifications and sizes. The electrical cabinet 2 is fixedly connected to the fixing holes 51 at the corresponding positions by handle screws 52. The electrical cabinet 2 can be fixedly connected by its own mounting process holes 21, which simplifies the fixing structure, reduces costs, and improves work efficiency.

[0042] In this embodiment, the fixing structure 5 also provides another implementation method, namely, the fixing structure 5 includes a plurality of slots (not shown in the figure) arranged along the length direction on the support surface 4, and the electrical cabinet 2 is fixedly connected to the slots at the corresponding positions by buckles (not shown in the figure).

[0043] In this embodiment, the locking mechanism 6 is installed on the outer side panel of the telescopic part 112 and the telescopic part 122 facing the electrical cabinet 2. This facilitates the operator to adjust the corresponding locking mechanism 6 from the outside of the electrical cabinet 2. The two movable bases 1 are arranged on the left and right sides respectively, and are marked on the movable bases 1, so as to ensure that both movable bases 1 can be operated from the outside of the electrical cabinet 2.

[0044] In this embodiment, the locking mechanism 6 is further preferably provided with at least two mounting holes 61 arranged along the length direction on the side of the telescopic part 112 of the first section 11 and an elongated oval hole 62 extending along the length direction on the side of the telescopic part 122 of the second section 12. The mounting holes 61 and the elongated oval hole 62 are fixed by fasteners. Here, the fastener is preferably a five-star handle 63. After adjustment, the five-star handle 63 can be tightened by hand to lock the movable base 1 to the required length. In order to make the locking more secure, the mounting holes 61 are respectively provided on the two side plates of the telescopic part 112 of the first section 11, and an elongated oval hole 62 is respectively provided on the two side plates of the telescopic part 112 of the second section 12. The five-star handle 63 passes through the mounting holes 61 and the elongated oval holes 62 on the two side plates at the same time to achieve locking.

[0045] The following details the floor transfer steps for electrical cabinet 2:

[0046] 1. Make initial adjustments to the telescopic length of the movable base 1, place the frame of the electrical cabinet 2 on the two movable bases 1, fine-tune the length of the two movable bases 1, and tighten the five-star handle 63 on the side of the movable base 1 to fix the movable base to the required length after adjustment.

[0047] 2. Use handle screws 52 to fix the mounting holes at the bottom of the electrical cabinet 2 to the fixing holes 51 on the mobile base 1, thereby fixing the electrical cabinet 2 to the mobile base 1.

[0048] 3. Move the frame of electrical cabinet 2 and the movable base 1 together to the assembly station, and assemble and wire electrical cabinet 2.

[0049] 4. After completion, move the assembled electrical cabinet 2 and the movable base 1 together to the test area, move the movable base 1 from under the electrical cabinet 2, and conduct a safety test on the electrical cabinet 2 in the test area.

[0050] The above solution has the following beneficial effects:

[0051] 1. The device uses two relatively independent movable bases 1 to support the electrical cabinet 2. The support distance between the two movable bases 1 can be flexibly adjusted according to the size of the electrical cabinet 2, so that the device can be used for electrical cabinets of any size and specifications, with strong versatility, and can ensure the stability and reliability of the support.

[0052] 2. The device can also directly complete the assembly and wiring of the electrical cabinet 2 on the mobile base 1, making the device integrate multiple functions such as support, ground transfer and assembly of the electrical cabinet assembly process. It is easy to use. When assembly and wiring work is required, there is no need to move the electrical cabinet frame to a fixed position, which improves the assembly efficiency of the electrical cabinet and reduces the labor intensity of the work.

[0053] 3. This device can directly install the frame of electrical cabinet 2 onto the mobile base 1. The frame of electrical cabinet is relatively light and easy to move. The mobile base 1 is removed only after electrical cabinet 1 is completed. It achieves functions such as flexible movement and stable support. It has high stability and high load-bearing capacity, and can ensure safety under heavy load.

[0054] 4. In this device, the electrical cabinet is fixed to the mobile base 1 by the fixed structure 5, which can ensure the stability of the electrical cabinet during movement, assembly and wiring, and prevent accidents such as tipping over, thus ensuring safe operation.
