Description

Technical Field

[0001] This utility model relates to the field of electric railcar technology, specifically to an electric flatcar that can be lifted as a whole. Background Technology

[0002] In modern industry and logistics, liftable electric flatbed carts have become important transportation tools due to their high efficiency and flexibility. Through an electric control system, they precisely adjust the platform height to adapt to different loading and unloading scenarios and equipment. With advantages such as high automation, ease of operation, and strong load-bearing capacity, they are widely used in workshop transfers, warehousing logistics, and other scenarios, effectively improving handling efficiency and reducing labor costs and safety risks.

[0003] As global manufacturing continues its transformation towards large-scale, intelligent, and assembly-line production, large and complex equipment often requires multiple transfers or assembly steps to produce the final product. During these transfers, various devices or platforms need to be connected, and the worktable heights in these complex scenarios are often inconsistent. To address these transportation conditions and reduce the complexity of multi-tool collaborative operations, an electric railcar with stable lifting capabilities is needed. Existing electric railcars typically use segmented platform panels for lifting, achieving the equipment's lifting function by raising and lowering portions of the platform. However, this lifting method reduces the equipment's load-bearing surface, concentrates the load, and easily causes uneven loading during asynchronous lifting. The combination of these factors can lead to equipment deformation or even damage, affecting normal equipment transport efficiency and safety. To address the shortcomings of existing technologies, this invention provides an electric flatbed cart that can be lifted as a whole to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electric flatcar that can be lifted as a whole. This solves the problems that electric railcars using this lifting mode cause the equipment's load-bearing surface to shrink, the load to become more concentrated, and the equipment to be prone to uneven load when lifting at different times. The combination of these two issues can easily lead to equipment deformation or even damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric flatbed cart that can be lifted as a whole, comprising:

[0006] Chassis assembly;

[0007] The drive wheel assembly is mounted on the frame assembly;

[0008] The passive wheel assembly is mounted on the frame assembly, and the driving wheel assembly and the passive wheel assembly serve as an actuation unit;

[0009] The dispatching and control system is fixedly connected to the front of the vehicle frame assembly. The dispatching and control system is used to precisely control the lifting height process of the electric railcar.

[0010] A laser obstacle avoidance assembly is located at the bottom of one end of the vehicle frame assembly. The laser obstacle avoidance assembly is used to detect obstacles during the operation of the electric railcar.

[0011] A hydraulic valve assembly, located in the middle of the frame assembly, is used to ensure the synchronous lifting and lowering of the cylinder rods in the drive wheel assembly and the driven wheel assembly.

[0012] Preferably, a housing assembly is fixedly connected to the joint of the frame assembly, and a safety contact edge is provided on the housing assembly. The frame assembly, the housing assembly, and the safety contact edge constitute a platform for height adjustment.

[0013] Preferably, a hydraulic oil tank is fixedly connected to the frame assembly, the hydraulic valve assembly is connected to the hydraulic oil tank, and a hydraulic pump station is provided at the end of the hydraulic valve assembly away from the hydraulic oil tank. The hydraulic oil tank, the hydraulic valve assembly and the hydraulic pump station constitute a power unit.

[0014] Preferably, a battery pack is fixedly connected to the frame assembly, and the battery pack is used to power the electric railcar.

[0015] Preferably, a ranging device is provided on one side of the laser obstacle avoidance assembly, a sensor assembly is provided on the frame assembly, and a proximity switch assembly is provided at one end of the drive wheel assembly.

[0016] Preferably, the frame assembly is provided with an oil receiving groove, and an automatic charging assembly is provided on the front of the frame assembly, the automatic charging assembly being connected to the battery pack.

[0017] This utility model discloses an electric flatbed cart that can be lifted and lowered as a whole, which has the following beneficial effects:

[0018] This electrically powered flatcar, capable of being lifted as a whole, employs a liftable wheel assembly structure. The lifting motion of the wheel assembly drives the entire electric railcar to rise, ensuring continuous contact between the platform of the electric railcar and the transport equipment during the lifting process, thus preventing changes in the stress state of the load-bearing surface. The principle of this invention is based on hydraulic cylinders transmitting force to the preset track platform through the wheel assembly. The reaction force of the preset track achieves the overall height increase of the electric railcar. Since the lifting motion is performed entirely by the electric railcar, it has no impact on the stress state of the transport equipment's load-bearing surface, effectively preventing deformation or even damage caused by concentrated loads on the equipment. This electric railcar system not only solves the problem of a single vehicle handling multiple workstation height differences but also eliminates the risk of equipment deformation or damage due to concentrated loads during lifting, significantly improving the efficiency of transport operations and the safety of transport equipment.

[0025] This application provides an electric flatcar that can be lifted as a whole, solving the problems of reduced load-bearing surface, more concentrated load, and uneven load on the equipment during asynchronous lifting of electric railcars, which can easily lead to deformation or even damage. The solution is a liftable wheel assembly structure.

The dispatch control system 5, the ranging device 12, the sensor assembly 14 and the proximity switch assembly 15 are connected to form a control unit.

[0048] The platform that enables height adjustment consists of a frame assembly 1, a shell assembly 4, and a safety contact edge 16. The power unit that enables the platform to lift height includes a drive wheel assembly 2, a driven wheel assembly 3, a hydraulic oil tank 8, a hydraulic valve assembly 9, and a hydraulic pump station 10.

[0049] The dispatching and control system 5 calculates the height of the electric railcar and the docking station based on the height measured by the ranging device 12 and sensor assembly 14. The resulting numerical information is divided into positive and negative values. Based on these values, the real-time height difference of the electric railcar is determined, driving the cylinder rod of the hydraulic pump station 10 to extend / retract. This causes relative sliding between the drive wheel assembly 2, the driven wheel assembly 3, and the frame assembly 1. Through the reaction force between the wheel assembly and the rail, the electric railcar is lifted as a whole, thus adjusting its height. During the lifting process, the ranging device 12 and sensor assembly 14 continuously provide real-time feedback on the height difference, allowing the dispatching and control system 5 to precisely control the lifting process of the electric railcar.

[0050] Once the electric railcar has reached its designated position, the dispatch control system 5 sends a pressure-maintaining command based on the actual situation fed back by the ranging device 12 and the sensor assembly 14. To ensure the overall synchronous lifting of the electric railcar during the lifting process, a hydraulic valve assembly 9 is installed in the middle of the electric railcar to adjust and control the oil pressure in real time, ensuring that the cylinder rods in the drive wheel assembly 2 and the driven wheel assembly 3 lift synchronously. Based on the measurement data from the ranging device 12, the sensor assembly 14, and the proximity switch assembly 15, the required height is confirmed and a signal is fed back to the dispatch control system 5. Multiple measurement calculations ensure precise and controllable height lifting, enabling it to meet the needs of transfer equipment in various transmission scenarios. This electric flatcar, which can be lifted as a whole, ensures that the electric railcar platform and the equipment remain in continuous contact during the lifting process, maintaining a constant overall stress state, thereby reducing equipment deformation caused by stress changes.
