Description

Technical Field

[0001] This utility model belongs to the field of electric locomotive maintenance technology, and more specifically, relates to a rotating device for maintaining the floor of an electric locomotive corridor. Background Technology

[0002] In the maintenance of Harmony D3 electric locomotives, corridor floor inspection is a crucial process. Currently, traditional methods for inspecting electric locomotive corridor floors mostly rely on manual rotation on a platform or manual moving. Manual rotation requires significant manpower, is labor-intensive, and causes wear and tear on the floor surface and aluminum alloy trim. The effectiveness is significantly affected by operator experience and condition, making stability difficult to guarantee. Simple work platform devices lack adaptability to changes in the size and shape of the corridor floor, resulting in fluctuating rotation performance under different working conditions. This can easily lead to bumps or damage to the corridor floor during inspection, affecting product quality, reducing production efficiency, and increasing production costs. Therefore, there is an urgent need to develop a new type of rotating inspection device that overcomes these problems, enabling stable and high-quality completion of floor inspection work. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a rotating device for the maintenance of electric locomotive corridor floors. This rotating device solves the technical problems of low maintenance quality and efficiency caused by the high manpower consumption and unstable maintenance results of manual assisted reversal during the maintenance of electric locomotive corridor floors, as well as the difficulty of adapting simple work platforms to changes in floor size or shape.

[0004] To achieve the above objectives, this utility model provides a rotating device for maintenance of the floor of an electric locomotive corridor, comprising: The tabletop is used to fit against the center of the corridor floor; A support column is connected to the center of the lower side of the tabletop; A first bearing is sleeved in the middle of the support column, and an upper support structure is provided between the first bearing and the support column.

[0005] Preferably, the upper support structure includes a plurality of upper connecting pipes, which are arranged obliquely, with the upper end of the upper connecting pipe connected to the outer periphery of the tabletop and the lower end of the upper connecting pipe connected to the middle of the support column.

[0006] Preferably, the upper connecting pipes are evenly distributed around the outer periphery of the tabletop.

[0007] Preferably, the tooling base is cross-shaped, and the lower support structure includes four lower connecting pipes. The upper end of the lower connecting pipe is connected to the bearing seat of the first bearing, and the lower end of the lower connecting pipe is connected to the outer peripheral end of the tooling base.

[0008] Preferably, the bearing housing of the first bearing has an arc-shaped outer surface.

[0009] Preferably, the outer periphery of the tooling base is provided with a support structure.

[0010] Preferably, the support structure is a caster wheel.

[0011] Preferably, the support structure is a screw fastening ring.

[0012] Preferably, the tabletop is a circular plate, the upper surface of the tabletop is covered with a nylon tablecloth, and the outer perimeter of the tabletop is covered with adhesive strips.

[0013] This utility model provides a rotating device for the maintenance of electric locomotive corridor floors.

[0017] Explanation of reference numerals in the attached figures: 1. Tabletop; 2. Support column; 3. First bearing; 4. Second bearing; 5. Tooling base; 6. Upper connecting pipe; 7. Lower connecting pipe; 8. Casters. Detailed Implementation

[0018] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0019] like Figure 1 As shown, this utility model provides a rotating device for maintenance of the floor of an electric locomotive corridor, comprising: Tabletop 1, used to fit against the center of the corridor floor; Support column 2 is connected to the center of the lower side of tabletop 1; The first bearing 3 is sleeved in the middle of the support column 2, and an upper support structure is provided between the first bearing 3 and the support column 2. The tooling base 5 is located below the support column 2. The tooling base 5 is equipped with a second bearing 4, which is sleeved on the bottom of the support column 2. A lower support structure is provided between the tooling base 5 and the first bearing 3.

[0020] Specifically, the rotating device supports the corridor floor via a table 1. A support column 2 is connected to the bottom of the table 1. The middle of the support column 2 is rotatably connected to the lower support structure via a first bearing 3, and the bottom of the support column 2 is rotatably connected to the tooling base 5 via a second bearing 4. The two bearings allow the support column 2 to rotate easily. When workers install accessories on the four corners of the corridor floor, they do not need to walk back and forth around the bottom of the floor. Workers only need to stand in one position to install. After the accessories on one corner of the floor are installed, rotating the support column 2 will drive the table 1 and the corridor floor to rotate. When the rotation reaches the next corner of the floor where no accessories are installed, it stops, and the accessories are installed. After installation, the rotation continues until all accessories on the entire floor are installed, and then the floor can be transferred to the locomotive.

[0021] This rotating device uses two bearings as its core rotating components. Based on the rotational principle of bearings, suitable load-bearing bearings are selected by comparing two core parameters: rated dynamic load and rated static load. This allows the bearings and bearing housings to provide stable rotational capabilities adapted to different sizes and shapes of corridor floors. The two bearings and support column 2 are interference-fitted.

[0022] Preferably, the upper support structure includes multiple upper connecting pipes 6, which are arranged obliquely. The upper end of the upper connecting pipe 6 is connected to the outer periphery of the tabletop 1, and the lower end of the upper connecting pipe 6 is connected to the middle of the support column 2.

[0023] Preferably, the upper connecting pipes 6 are evenly distributed around the outer periphery of the tabletop 1.

[0024] Specifically, multiple upper connecting pipes 6 are obliquely arranged between the tabletop 1 and the support column 2. The upper end of the upper connecting pipe 6 is connected to the lower outer surface of the tabletop 1, and the lower end of the upper connecting pipe 6 is connected to the support column 2. This connection position is located directly above the first bearing 3, and the connection position is 3-5cm away from the first bearing 3. The upper connecting pipe 6 provides support and connection to the outer periphery of the tabletop 1, and the support column 2 provides support and connection to the center position of the tabletop 1. The tabletop 1 is stably set in the horizontal direction. When the middle of the floor is supported by the tabletop 1, the tabletop 1, the support column 2 and all the upper connecting pipes 6 can form a stable support structure, supporting the floor and allowing the floor to rotate when needed.

[0025] Preferably, the tooling base 5 is cross-shaped, and the lower support structure includes four lower connecting pipes 7. The upper end of the lower connecting pipe 7 is connected to the bearing seat of the first bearing 3, and the lower end of the lower connecting pipe 7 is connected to the outer peripheral end of the tooling base 5.

[0026] Preferably, the bearing seat of the first bearing 3 is provided with an arc-shaped outer surface.

[0027] Specifically, the tooling base 5 is set in a cross shape, and the four ends of the tooling base 5 are respectively connected to the lower connecting pipe 7. The upper end of the lower connecting pipe 7 is connected to the bearing seat of the first bearing 3. Since the bearing seat has a rounded surface, it is convenient to weld the lower connecting pipe 7 to increase the stability of the tooling. Each branch on the tooling base 5, the lower connecting pipe 7 and the support column 2 form a triangular stable structure, so that the two bearings can be stably set. Under the action of the bearing, the support column 2 drives the table 1 to rotate stably.

[0028] Multiple upper connecting pipes 6 are obliquely welded between the support rod and the table 1 to stabilize and strengthen the table 1; a lower connecting pipe 7 is welded between the end of the tooling base 5 and the first bearing 3 to distinguish the primary and secondary components structurally. The lower connecting pipe 7 serves as the primary support, and its longer inclined side and larger area highlight its role in bearing key forces, creating a dual functional and visual difference with the upper connecting pipes 6, which serve as auxiliary supports.

[0029] Preferably, the outer periphery of the tooling base 5 is provided with a support structure.

[0030] Preferably, the support structure is a caster wheel 8.

[0031] Preferably, the support structure is a screw fastening ring.

[0032] Specifically, the end of the tooling base 5 can use casters 8 as a support structure, which can drive the floor maintenance rotation device to move flexibly. Alternatively, screw fastening rings can be used as a support structure, so that the floor maintenance rotation device is fixed in a designated position, preventing the entire device from shifting and affecting the normal rotation of the floor.

[0033] Preferably, the tabletop 1 is a circular plate, the upper surface of the tabletop 1 is covered with a nylon tablecloth, and the outer periphery of the tabletop 1 is covered with adhesive strips.

[0034] Specifically, to enhance protective performance, a nylon tablecloth was added to the upper surface of tabletop 1, and anti-collision rubber strips were added around the perimeter of tabletop 1. These measures can effectively buffer the impact of collisions and provide protection against bumps and knocks, while also protecting the edges of the tabletop and personnel, thereby ensuring the quality of maintenance of the corridor floor.

[0035] In summary, during the use of this corridor floor maintenance rotating device, the floorboard to be installed is placed on the circular table 1, with the center of the floorboard aligned with the table 1. Then, a worker installs a component at one corner of the floorboard from a fixed position. After the corner component is installed, a rotational force is applied to the upper connecting pipe 6, causing the table 1 to rotate, thus rotating the floorboard. The rotation stops when the next component needs to be installed, and the installation continues until all components are installed. The floorboard is then transferred to the vehicle. During the rotation, both ends of the upper connecting pipe 6 are connected to the support column 2 and the table 1 respectively, providing stable support for the table 1. This creates a stable support structure under the table 1, ensuring easy rotation of the floorboard when it rotates. Furthermore, a lower connecting pipe 7 connects between the first bearing 3 and the outer periphery of the tooling base 5. This forms a stable triangular structure with the tooling base 5, support column 2, and lower connecting pipe 7. The first bearing 3 and the second bearing 4 are positioned stably, allowing the support column 2 to rotate easily under the action of the two bearings, ensuring smooth floorboard installation.

[0036] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
