Description

Technical Field

[0001] The invention relates to the technical field of train ferries, and in particular to a novel train track fixing device and method for train ferries. Background Art

[0002] A train ferry is a ship specially designed to carry railway vehicles for cross-water transportation. Its main function is to achieve seamless connection between rail transportation and water transportation by carrying a standard gauge railway track system. This mode of transportation plays an important role in areas where the railway network is discontinuous. It has the advantages of efficiently connecting the transportation network, reducing transportation costs and shortening logistics time. It is widely used in bulk cargo and long-distance transportation. Train ferries are usually equipped with stable track fixtures to ensure that the train carriages remain stable during the voyage of the ship. They are suitable for transportation needs across geographical barriers such as straits, rivers or lakes.

[0025] like Figure 1 and Figure 2 As shown, a novel train track fixing device for a train ferry in this embodiment includes a web 2, a pad 3, a clamp 5, and a bolt 9. The web 2 is fixed to the ship deck 1 by welding, and the pad 3 is placed on the upper surface of the web 2 for laying train tracks. The clamp 5 is symmetrically arranged on both sides of the train track 4, and the clamp 5 is fixed to the web 2 by bolts 9.

[0026] like Figures 3 to 5 As shown, the clamp 5 includes an upper clamp 6, a lower clamp 7 and a side wall 8 connecting the upper clamp 6 and the lower clamp 7. The lower clamp 7 is installed on the web 2, and the upper clamp 6 is used to press the upper surface of the train track 4. When the clamp 5 is installed on the web, the upper surface of the upper clamp 6 is parallel to the upper surface of the web 2 to facilitate the installation of the bolts. The upper clamp 6, the lower clamp 7 and the web 2 are all provided with openings, and the bolts 9 are installed in the openings to fix the clamp 5 on the web 2. The bolt 9 is also provided with a nut 10 and a gasket 11. The gasket 11 is located between the nut 10 and the upper surface of the upper clamp 6, and the friction of the bolt is increased by the gasket. The bolt 9 is a high-strength bolt to improve the fixing strength.

[0027] The pad 3 is made of nitrile rubber (NBR). By adjusting the thickness of the rubber pad 3, the train tracks are ensured to be at the same level, the installation accuracy is improved, and the load on the track is buffered.

[0028] A piezoresistor sensor is provided on the upper surface of the train track 4, and the lower surface of the upper clamp 6 is buckled onto the piezoresistor sensor. When the train track receives a load, the piezoresistor sensor generates a resistance signal change due to the pressure, and the pressure condition of the upper surface of the train track can be monitored by the resistance signal change. Since the pressure position of the upper clamp 6 is fixed, when the train track continues to press on the pad 3 and the thickness of the pad 3 changes, the horizontal height of the train track will be reduced, so that the train track is out of contact with the upper clamp 6 in the height direction, the piezoresistor sensor on the train track loses force, and the resistance signal will return to its original state. Therefore, by monitoring the resistance signal of the piezoresistor sensor, the pressure condition of the upper surface of the train track can be monitored, so that the rubber pad can be replaced or repaired in time to ensure that the horizontal height of the train track is always within the specified height range.

[0029] The fixing method of the novel train track fixing device of the present invention comprises the following steps:

[0030] S1, fixing the web 2 on the ship deck;

[0031] S2, determining the height of the pad 3 according to the preset train track installation height and the web height, and laying the pad 3 on the web 2;

[0032] S3, placing the train track on the pad 3;

[0033] S4, symmetrically arrange the clamps 5 on both sides of the train track, and make the lower surface of the upper clamp 6 press against the upper surface of the train track;

[0034] S5. Fix the clamp 5 to the web 2 with bolts 9.

[0035] The present invention fixes the train track by means of a clamp, wherein the upper clamp presses the train track, the lower clamp is connected to the web, and the web is fixed on the deck, thereby improving the fixing strength and stability of the track-deck connection structure; the horizontal height of the train track is ensured to be within a specified height range by adjusting the thickness of the cushion block, and the cushion block is made of nitrile rubber (NBR) material, which can effectively buffer the track load and protect the deck.
