Description

Technical Field

[0001] This utility model relates to the field of cargo transportation, and in particular to an electric trailer for railway tunnel rescue. Background Technology

[0002] Currently, the demand for lightweight and modular equipment is becoming increasingly prominent in the field of rail transit rescue.

[0003] Most existing powered trailers adopt an integral structure design, and their running gear usually relies on external power for traction. The rescue module is rigidly connected to the vehicle body, and the energy supply system requires additional power generation equipment.

[0004] Existing technologies reveal key drawbacks: the integrated structure results in individual components typically weighing over 80kg, posing a risk of falling during manual assembly and disassembly. The gear transmission mechanism of the traditional running gear occupies significantly more space than the electric wheels, necessitating a dedicated storage rack for the rescue vehicle when not in operation. The fixed connection between the hydraulic system and the power unit prevents the energy department from quickly switching between battery and hydraulic pump station combinations based on operating conditions. Therefore, a railway tunnel rescue electric trailer is proposed to address these issues. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1-3 This utility model provides an embodiment of an electric trailer for railway tunnel rescue, comprising a walking section, a rescue section, and an energy section. The walking section includes a side bearing 1, with an electric wheel 2 installed inside the side bearing 1, and a support beam 3 installed on the top of the side bearing 1. An energy trolley connection hole 3.1 is provided on the outer side of the support beam 3. The rescue section includes a sliding trolley 4, with a sinking hydraulic cylinder 5 installed at the bottom of the sliding trolley 4, a walking support 6 installed on the top of the sliding trolley 4, a freight car top cap 7 installed on the top of the walking support 6, and a transverse hydraulic cylinder 8 installed on the top of the support beam 3. A transverse hydraulic cylinder base 9 is provided on the top side of the transverse hydraulic cylinder 8. The energy section includes an energy trolley 10, a multi-functional power supply 11, and a small hydraulic station 12.

[0013] Specifically, the electric wheel 2 is placed on the track, and after it is stabilized, the side bearing 1 is fastened to the support seat 2.4 of the electric wheel 2; then the support beam 3 is placed on the side bearing 1, thus completing the installation of the trolley's traveling mechanism. The rescue mechanism consists of a sliding trolley 4, a sinking hydraulic cylinder, a lateral hydraulic cylinder base 9, a lateral hydraulic cylinder 8, and a truck top cap 7. The sinking hydraulic cylinder is used to lift and support the truck after it derails, while the lateral hydraulic cylinder base 9 and the lateral hydraulic cylinder 8 can laterally move the lifted truck back to its original position. After resetting, the connecting oil pipe on the lifting hydraulic cylinder is removed, and the traveling support 6 is installed, allowing the truck to be dragged out of the tunnel via the traveling mechanism.

[0014] Reference Figures 4-5 The electric wheel 2 includes a motor fixing shaft 2.1, a support seat 2.4 on the outer side of the motor fixing shaft 2.1, a bearing 2.3 inside the support seat 2.4, a support seat cover 2.2 on the outer side of the motor fixing shaft 2.1, a track wheel 2.7 on the outer side of the middle part of the motor fixing shaft 2.1, a limit screw 2.6 inside the track wheel 2.7, a support cover 2.5 on the outer side of the motor fixing shaft 2.1, and a hub motor 2.8 installed inside the track wheel 2.7.

[0015] Specifically, the walking unit mainly relies on the hub motor 2.8 inside the electric wheel to achieve the walking function. After being powered on, it can be controlled by remote control. The energy unit provides power to the walking unit and the rescue unit, but when walking, the energy vehicle 10 of the energy unit needs to be connected to the walking unit to move with the help of the walking unit.

[0016] Reference Figures 6-9 The energy vehicle 10 includes a pump station limiting frame 10.1, a rotating shaft bearing seat 10.6, a multi-functional power supply limiting frame 10.8, and a limiting plate 10.9. Two rotating cams 10.2 are arranged on the outer side of the rotating shaft bearing seat 10.6, and a rotating connecting rod 10.3 is arranged between the two rotating cams 10.2. A disconnect threaded hole 10.4 and a connection threaded hole 10.5 are provided on the outer side of the rotating shaft bearing seat 10.6. Two rotating shafts 10.7 are arranged on the outer side of the rotating connecting rod 10.3. A connecting hole 10.3.1 is provided on the outer side of the rotating connecting rod 10.3.

[0017] Specifically, after installing the walking unit, move the energy trolley 10 to the front of the walking unit, align the limiting plate 10.9 of the energy trolley 10 with and insert it into the energy trolley connecting hole 3.1 on the walking unit support beam 3. Then remove the bolts from the disconnect threaded hole 10. After that, move the rotating connecting rod 10.3. The rotating connecting rod 10.3 drives the rotating shaft 10.7 and the limiting plate 10.9 to rotate through the rotating cam 10.2. When the fixing hole on the rotating connecting rod 10.3 is aligned with the connecting threaded hole 10.5, it can be fixed with bolts. At this time, the rotation angle of the rotating cam 10.2 is 90°.

[0018] Working principle: Place the electric wheel 2 on the track, and after it is stable, fasten the side bearing 1 onto the support seat 2.4 of the electric wheel 2; then place the support beam 3 on the side bearing 1 to complete the installation of the trolley traveling part. The rescue part consists of a sliding trolley 4, a sinking hydraulic cylinder, a lateral hydraulic cylinder base 9, a lateral hydraulic cylinder 8, and a truck top cap 7. The sinking hydraulic cylinder is used to lift and support the truck after it derails, while the lateral hydraulic cylinder base 9 and the lateral hydraulic cylinder 8 can laterally move the lifted truck back to its original position. After resetting, disconnect the connecting oil pipe on the lifting hydraulic cylinder, install the traveling support 6, and the truck can be dragged out of the tunnel by the traveling part.

[0019] The walking unit primarily relies on the hub motor 2.8 inside the electric wheels for mobility. It can be controlled remotely after being powered on. The energy unit provides power to both the walking and rescue units. However, for mobility, the energy trolley 10 of the energy unit must be connected to the walking unit. After installing the walking unit, move the energy trolley 10 to the front of the walking unit, aligning and inserting the limiting plate 10.9 of the energy trolley 10 into the energy trolley connection hole 3.1 on the walking unit support beam 3. Then, remove the bolt from the disconnect threaded hole 10. Next, move the rotating connecting rod 10.3. The rotating connecting rod 10.3 drives the rotating shaft 10.7 and the limiting plate 10.9 to rotate via the rotating cam 10.2. When the fixing hole on the rotating connecting rod 10.3 aligns with the connection threaded hole 10.5, it can be secured with bolts. At this point, the rotation angle of the rotating cam 10.2 is 90°.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
