Description

Technical Field

[0001] This utility model relates to the field of electric railcar technology, specifically to a lifting wheel box structure for an electric flatcar. Background Technology

[0002] In modern industrial settings, the lifting wheel assembly of the electric railcar adopts a modular design, driven by high-precision hydraulic or electric push rods, and combined with a high-strength guide rail system, enabling rapid and precise lifting. The materials used are lightweight alloys and wear-resistant engineering plastics to ensure efficient, safe, and stable operation.

[0003] As global manufacturing continues its transformation towards large-scale, intelligent, and assembly-line production, some large and complex equipment often requires multiple transfers or assembly steps to complete the final product. During these transfers, various equipment or platforms need to be connected, and the worktable heights in these complex scenarios are often inconsistent. Currently, most electric railcars use a fixed wheel set structure. Once this structure is determined, the height of the electric railcar's worktable panel is also fixed. On the one hand, a single vehicle is not suitable for handling the height differences between multiple workstations; on the other hand, the requirements for the equipment transport and docking site are relatively high. To address the shortcomings of existing technologies, this utility model provides a lifting wheel box structure for electric flatcars to solve the above problems. Utility Model Content

[0017] This utility model discloses a lifting wheel box structure for electric flatbed carts, which has the following beneficial effects:

[0018] This lifting wheel box structure for electric flatcars adopts a liftable wheel set structure.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This application provides a lifting wheel box structure for electric flatcars, solving the problem that once the structure is determined, the height of the electric railcar's workbench panel is also fixed. This makes it difficult for a single vehicle to handle height differences between multiple workstations, and also addresses the high requirements for equipment transport docking sites. The solution utilizes a liftable wheel set 8 structure. As a key component of the electric railcar, the wheel set 8 directly determines its load-bearing capacity and operating efficiency. Therefore, this invention not only meets the flattening requirements of the electric railcar's wheel set 8 structure but also serves as a carrier for adjusting the overall height of the electric railcar, reducing the requirements for equipment transport docking sites and adapting to complex workstation transport scenarios. The principle of this invention is based on hydraulic cylinders acting on the wheel set 8 system. The reaction force of the wheel set 8 on the rails achieves the lifting and lowering of the overall height of the electric railcar. During operation, only the entire electric railcar is lifted, without affecting the load-bearing surface of the transport equipment. This structure solves the problem of a single vehicle handling height differences between multiple workstations, significantly improving transport efficiency and the safety of the transport equipment.

The guide block 6 slides up and down along the guide groove 4 in the wheel set 8 to play a guiding role and ensure the smoothness and verticality of the lifting process.

[0033] The wheel bearing seat pad 2 is provided with a wheel set 8 at the bottom, and the wheel set 8 is used for the movement of the electric railcar.

[0034] The wheel assembly 8 is used for the movement of the electric railcar. The wheel base 1 and the wheel bearing seat pad 2 provide support and limit the movement of the wheel assembly 8. This utility model structure uses the wheel assembly 8 as the load-bearing point, which acts on the frame of the electric railcar without affecting the stress on the platform of the electric railcar or the transport equipment. This utility model structure solves the problem of adjustable platform height for electric railcars.

[0035] Example 2: According to the appendix Figure 1 As shown, it includes:

[0036] The wheel base 1 serves as the basic support component for the wheel assembly 8, providing a mounting base for other parts.

[0037] The wheel bearing seat pad 2 is fixedly connected between the wheel base 1. The wheel bearing seat pad 2 plays the role of supporting and positioning the wheel assembly 8, ensuring the stability and accuracy of the wheel assembly 8 installation.

[0038] The guide groove 4 is fixedly connected to the end of the wheel base 1 away from the wheel bearing seat 2. The guide groove 4 provides a sliding track for the guide block 6 in the lifting mechanism to ensure the smoothness and accuracy of the lifting process.

[0039] The hydraulic cylinder assembly 9 is fixedly connected to the wheel base 1. The hydraulic cylinder assembly 9 provides lifting power, and the cylinder rod in it achieves the lifting function through telescopic movement.

[0040] The fixing plate 5 is located above the hydraulic cylinder assembly 9. As part of the lifting mechanism, the fixing plate 5 is used to connect and fix other components and provide mounting support for the cylinder rod of the hydraulic cylinder assembly 9.

[0041] The guide block 6 is slidably connected to the guide groove 4 at its bottom and fixedly connected to the side wall of the fixed plate 5 at its upper end. The guide block 6 slides up and down along the guide groove 4 in the wheel set 8 to play a guiding role and ensure the smoothness and verticality of the lifting process.

[0042] The bottom of the fixed plate 5 is fixedly connected to the connecting flange 7, which is fixedly connected to the output end of the hydraulic cylinder assembly 9 by bolts.

[0043] The fixed plate 5, guide block 6, connecting flange 7 and hydraulic cylinder assembly 9 constitute the lifting mechanism.

[0044] A sensor block 3 is fixedly connected to the wheel bearing seat plate 2. The sensor block 3 is used to detect the height position of the lifting mechanism.

[0045] The wheel bearing seat pad 2 is provided with a wheel set 8 at the bottom, and the wheel set 8 is used for the movement of the electric railcar.

[0046] A flow divider 10 is fixedly connected to the wheel bearing seat pad 2. The flow divider 10 is used to adjust and control the oil pressure.

[0047] This utility model comprises a wheel assembly 8, a lifting mechanism, and a sensing unit. The wheel assembly 8 consists of a wheel base 1, a wheel bearing seat 2, a wheel set 8, a guide groove 4, and a diverter block 10. The wheel set 8, via the wheel bearing seat 2 and the wheel base 1 with the guide groove 4 already assembled, forms the main body of the wheel assembly 8 through fasteners. This main body not only serves as the wheel set 8 of the electric railcar but also functions as the base for the lifting mechanism. The lifting mechanism consists of a fixed plate 5, a hydraulic cylinder assembly 9, a guide block 6, and a connecting flange 7. The cylinder rod in the hydraulic cylinder assembly 9 is connected to the fixed plate 5 with the guide block 6 already assembled through the connecting flange 7, forming the lifting mechanism. The sensing unit uses a sensing block 3 as the actuator for controlling the lifting height of the lifting mechanism. Once the electric railcar is in position, a lifting command is sent based on the actual situation. This drives the cylinder rod in the hydraulic cylinder assembly 9 to extend, causing the guide block 6 in the lifting mechanism to slide up and down along the guide groove 4 in the wheel assembly 8. The reaction force between the wheel assembly 8 and the track causes the electric railcar to lift as a whole. To ensure the overall lifting of the electric railcar during the lifting process, a diverter block 10 is installed in the middle of the wheel assembly 8 for hydraulic pressure regulation and control, ensuring that the cylinder rods in the two sets of hydraulic cylinder assemblies 9 lift synchronously. The sensing block 3 confirms the required height based on the measurement data from the sensing unit and sends back a positioning signal.

[0048] The hydraulic cylinder assembly 9 in the lifting mechanism is driven by a height sensor to reciprocate, thereby raising and lowering the overall height of the electric railcar. This method meets the equipment transportation requirements between workstations with different height differences, reduces the crane lifting process, and improves work efficiency.
