Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a traveling lifting device for a heavy rail bogie. Background Art

[0002] In the field of railway construction and maintenance, the lifting and movement of heavy components is an indispensable and important link in the processes of installation, repair, replacement and train formation.

[0003] Currently, the common lifting and movement methods used in railway construction primarily include traditional crane operations and railcar-assisted lifting. Traditional crane operations rely on large lifting equipment such as truck cranes and tower cranes. While these devices offer strong lifting capabilities, they lack flexibility, making them particularly difficult to operate in narrow railway work sites and susceptible to site constraints. While railcar-assisted lifting improves mobility to a certain extent, it still requires additional lifting equipment and manpower, resulting in relatively low efficiency.

[0004] Traditional crane operations are often difficult to perform in complex railway operating environments due to site limitations, especially when precise lifting and moving of heavy components are required, which greatly increases the difficulty and cost of operations.

[0005] Whether it is a traditional crane or a rail car, it takes a lot of time and manpower to prepare equipment, arrange the site and perform lifting operations, resulting in low overall operation efficiency. Utility Model Content

[0006] The utility model aims at the technical problems existing in the prior art and provides a traveling crane hoisting device for a heavy rail bogie to solve the problem that the above-mentioned traditional crane is limited in use in a railway environment.

[0007] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a lifting device for a heavy rail bogie, wherein the X-direction and the Y-direction are two directions perpendicular to the horizontal direction, respectively, and include two groups of support frames relatively mounted on the bogie; an X-direction moving frame and an X-direction moving assembly connected to the X-direction moving frame are mounted on the support frame, and the X-direction moving assembly is used to drive the X-direction moving frame to move back and forth along the X-direction; a Y-direction moving frame and a Y-direction moving assembly connected to the Y-direction moving frame are also mounted on the X-direction moving frame; a lifting bobbin and a rotating mechanism connected to the lifting bobbin are installed on the Y-direction moving frame; a lifting rope is provided on the lifting bobbin, and a hook is installed at the bottom end of the lifting rope; the rotating mechanism is used to drive the lifting bobbin to rotate and wind the lifting rope to drive the hook to rise and fall.

[0011] An X-direction wheel assembly mounted on the X-direction movable frame and adapted to the X-direction guide rail;

[0012] A motor drive component 1 for driving the X-axis wheel set.

[0013] Furthermore, the Y-direction movable frame is a frame structure formed by cross-connecting X-direction beams and Y-direction beams, and a moving channel for the suspension rope is reserved in the frame structure.

[0014] Furthermore, the Y-moving component includes:

[0015] Two sets of Y guide rails are arranged oppositely on both sides of the moving channel of the suspension rope;

[0016] Y-direction wheel sets installed on both sides of the Y-direction movable frame and respectively adapted to the two Y-direction guide rails;

[0017] A driving spindle mounted on the Y-axis movable frame;

[0026] Motor drive part three for driving the bobbin gear.

[0027] Furthermore, the overhead crane device for heavy rail bogies provided by the present invention has at least the following beneficial effects compared to the prior art:

[0028] The heavy-rail bogie overhead crane hoisting device described in this application integrates X- and Y-axis motion components to achieve precise, multi-directional horizontal movement of heavy components. Compared to traditional crane operations and railcar-assisted lifting, this device eliminates the need for large lifting equipment and can be flexibly operated even in confined railway work sites, significantly improving operational flexibility and efficiency. Furthermore, the device is tightly integrated with the bogie to form an integrated system, further simplifying the operational process and reducing equipment preparation and site layout time.

[0036] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, the lifting device of the heavy rail bogie of the present utility design has the X-direction and Y-direction being two directions perpendicular to the horizontal direction, respectively, and includes two groups of support frames 1 relatively mounted on the bogie; an X-direction moving frame 2 and an X-direction moving assembly 3 connected to the X-direction moving frame 2 are mounted on the support frame 1, and the X-direction moving assembly 3 is used to drive the X-direction moving frame 2 to move back and forth along the X-direction; a Y-direction moving frame 4 and a Y-direction moving assembly 5 connected to the Y-direction moving frame 4 are also mounted on the X-direction moving frame 2; a lifting bobbin 6 and a rotating mechanism 7 connected to the lifting bobbin 6 are installed on the Y-direction moving frame 4; a lifting rope 8 is provided on the lifting bobbin 6, and a hook 9 is installed at the bottom end of the lifting rope 8; the rotating mechanism 7 is used to drive the lifting bobbin 6 to rotate and wind the lifting rope 8, so as to drive the hook 9 to rise and fall.

[0038] The overhead crane hoisting device of the present application is stably mounted on the bogie through a support frame 1, and utilizes X-direction and Y-direction moving components 3 and 5 to realize multi-directional movement in the horizontal direction. The rotating mechanism 7 drives the hoisting bobbin 6 to rotate and wind the hoisting rope 8 to realize lifting and lowering in the vertical direction, thereby forming an overall system that can be mounted on the heavy rail bogie and tightly integrated with the bogie, meeting the needs of precise lifting and moving of heavy components in railway construction and maintenance.

[0039] As an embodiment, the X-direction moving component 3 includes:

[0040] Two sets of X-direction guide rails 3.1 are respectively arranged along the X direction on the two sets of X-direction movable frames 2;

[0041] An X-direction wheel set 3.2 mounted on the X-direction movable frame 2 and adapted to the X-direction guide rail 3.1;

[0042] A motor drive 3.3 for driving the X-wheel set 3.2.

[0043] The X-direction moving assembly 3 realizes the precise horizontal movement of the X-direction moving frame 2 through the ingenious combination of the guide rail-wheel set and the motor drive, providing a solid foundation for the multi-directional movement capability of the entire overhead crane lifting device.

[0044] As an embodiment, the Y-axis movable frame 4 is a frame structure formed by intersecting X-axis beams and Y-axis beams, and a movement channel for the lifting rope 8 is reserved within the frame structure. The Y-axis movable frame 4 is formed by intersecting X-axis beams and Y-axis beams to form a stable frame structure. The movement channel of the lifting rope 8 is reserved inside to ensure that the lifting rope 8 can move freely and unobstructed when winding the lifting bobbin 6.

[0045] Specifically, the Y-moving component 5 includes:

[0046] Two sets of Y-guide rails 5.1 arranged oppositely on both sides of the moving channel of the suspension rope 8;

[0047] Y-direction wheel sets 5.2 are installed on both sides of the Y-direction movable frame 4 and are respectively adapted to the two Y-direction guide rails 5.1;

[0051] A motor drive part 5.6 is connected to the driving spindle 5.3.

[0052] The driven gear 5.5, which is connected to the Y-direction wheel set 5.2, meshes with the driving gear 5.4 to form a gear transmission system. When the driving spindle 5.3 rotates, the meshing transmission between the driving gear 5.4 and the driven gear 5.5 drives the Y-direction wheel set 5.2 to roll on the Y-direction guide rail 5.1, achieving Y-direction movement of the Y-direction moving frame 4.

[0053] Preferably, the motor drive component 2 5.6 is assembled from a drive motor and a commutator.

[0056] A gear plate 7.2 is provided on the outer ring of the lifting bobbin 6;

[0057] a bobbin gear 7.3 meshing with the gear plate 7.2;

[0058] A motor drive part 3 7.4 for driving the bobbin gear 7.3.

[0059] The rotating mechanism 7, through the precise coordination of the support shaft 7.1, gear plate 7.2, spool gear 7.3, and motor drive unit 3 7.4, controls the rotation of the lifting spool 6, thereby winding and releasing the lifting rope 8, completing the lifting and lowering movements during the lifting operation. This design is not only compact but also highly efficient, meeting the precision and stability requirements of lifting operations.

[0060] As a supplement, our crane hoist is designed for heavy rail bogies used in railway construction and maintenance, with a lifting area located directly above adjacent bogies. This device is not suitable for direct installation on existing track and requires the use of bogies, particularly when heavy components need to be lifted and moved between adjacent sets of bogies.

[0061] This device is particularly suitable for lifting and moving operations in railway construction and maintenance, such as installation, repair, replacement, and train formation. These operations often require lifting and moving heavy components, but traditional crane operations and railcar lifting methods are often plagued by site limitations and operational difficulties. This device can flexibly address these challenges, improving operational efficiency and safety.
