Description

Technical Field

[0001] The utility model belongs to the technical field of traction devices, and in particular relates to an energy-saving traction system for high-speed trains. Background Art

[0002] A high-speed train, also known as a high-speed train or a bullet train, refers to a train that can run continuously at a high speed. A high-speed train is a modern high-speed means of transportation. When a high-speed train moves at a station, it often requires a traction vehicle to tow it.

[0003] There are two common ways to tow high-speed trains on the market. One is to use a tractor to pull directly, and the other is to use a small amount of power to power the train and move on its own. When the tractor directly tows, due to the heavy weight of the train, a high amount of energy is required at the start, and it is easy to cause irreversible damage to the traction components. If the train is directly towed by a small amount of power, it will cause a waste of electricity during the movement of the vehicle. For this reason, we propose a high-speed train energy-saving traction system to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an energy-saving traction system for high-speed trains to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an energy-saving traction system for a high-speed train, comprising a shell, a connecting rod slidably connected inside the shell, a traction hook connected to the train welded to one end of the connecting rod, a screw rod welded to the other end of the connecting rod, a fixing frame threadedly connected to the circumferential outer side of the screw rod, and the fixing frame slides in the shell, a locking mechanism for fixing the screw rod and the fixing frame is provided on one side of the screw rod, a sensor induction frame is keyed connected to the circumferential outer wall of the connecting rod, a through hole is opened on the top of the shell, a displacement sensor is threadedly connected to the through hole, and the displacement sensor is used in conjunction with the sensor induction frame.

[0006] Preferably, the locking mechanism comprises a socket, which is provided on one side of the screw rod, and a latch is inserted into the socket, and the latch is a cotter pin.

[0007] Preferably, a plurality of slots are provided on one side of the fixing frame, and the plurality of slots are symmetrically distributed, and one end of the latch is located in the slot.

[0008] Preferably, a spring is bonded to an inner wall of one side of the shell, and one end of the spring is fixed to the sensor induction frame.

[0009] Preferably, fixing holes are provided on both sides of the shell, so that the shell can be fixed on the tractor.

[0010] Preferably, two support blocks are welded on both sides of the shell, and the two support blocks are fixed to two lugs with fixing holes.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the moving traction hook will squeeze the high-speed train, so that the traction hook, the connecting rod and the sensor sensing frame will slide together, and then be sensed by the displacement sensor. The displacement sensor transmits the signal to the high-speed train, so that the high-speed train provides a starting power, so that the high-speed train and the traction vehicle start at the same time, and the power supply of the high-speed train is stopped after starting. At this time, the traction vehicle can easily tow the high-speed train to move, thereby achieving energy-saving effects and improving the energy-saving performance of train traction.

The versatility of the device is improved.

[0019] The working principle and use process of the utility model are as follows: when the traction hook 5 is connected to the high-speed train, the moving traction hook 5 will squeeze the high-speed train, so that the traction hook 5, the connecting rod 9 and the sensor sensing frame 8 will slide together, and then be sensed by the displacement sensor 4.
