Problems solved by technology

According to relevant literature search, the main methods currently used on existing lines to prevent ballast pollution and prolong the cleaning cycle are: changing to asphalt road bed, using asbestos ballast on the surface layer, laying PVC soft board protective layer and magnesite cement protective layer. Although these solutions have a certain protective effect, they have not been popularized and applied due to the defects of difficult construction, high cost, environmental impact, short service life and poor waterproof performance.

Embodiment 1

[0035] This embodiment is located in a dust suppression station at the starting point of railway coal transportation in a certain place in North China. The station sprays dust suppression fluid on trains transporting coal. The train is a special train for heavy-duty coal transportation, and the speed of the train during spraying operation is 10km / h. The railway line is ballast bed, reinforced concrete sleeper. The design requires the use of the unilateral drainway bed protection device of the present invention, without considering the melting of ice in winter. The cross-section of the sleeper is trapezoidal, and the height of each part is different; the length of the sleeper is 2650mm, the distance between the sleepers (center distance) is 658mm, and the average distance between the sides of two adjacent sleepers is 405mm.

[0036]Depend on figure 1 , Figure 4 and Figure 7 As shown, the present embodiment is made up of components such as pallet shield 1, sleeper shield ...

Embodiment 2

[0052] This embodiment is applied to a mountainous section of a railway in the alpine region of northern my country. In summer, part of the road section has waterfall water splashing down on the track bed, and snow often occurs in winter. The track bed is protected by melting ice, melting snow and drainage by adopting the present invention.

[0053] The technical parameters of the ballast bed, the sleeper and each component of this embodiment are the same as those of Embodiment 1.

[0054] This embodiment puts forward the technical requirements for melting ice and snow in winter. Depend on Figure 11~Figure 13 As shown, a carbon fiber electric heating plate 7 is added between the sandwich layers 13 of the sleeper cover 2 and the drainage groove 3, and the layer structure is: 0.5mm wear-resistant and anti-aging gel coat layer 11+3mm reinforcement layer 12 +3mm (sandwich layer 13 / carbon fiber heating plate 7) +3mm reinforcement layer 12. The specification of the carbon fiber ...

Embodiment 3

[0062] This embodiment adopts double-sided drainage, by Figure 8 As shown, drainage ditches 5 are arranged on both sides of the ballast bed in this embodiment; bilateral drainage grooves 3a are arranged between the sleepers.

[0063] The technical parameters of the ballast bed, the sleeper and each component of this embodiment are the same as those of Embodiment 1.

[0064] The manufacturing and installation process of this embodiment is the same as that of Embodiment 1.

Abstract

The invention belongs to protection equipment of rail tracks, and particularly relates to a track bed ice-melting water-draining protection device which protects sleepers and ballasts in a shielding mode through sleeper protection covers, end protection covers, clamping plate protection covers, water-draining grooves with changeable width and other components. The variety of the components of the track bed ice-melting water-draining protection device is small, the specification is uniform, manufacturing is convenient, clamping bars and claming grooves are adopted between the components, and locking connection is achieved through elastic deformation. The structure is simple, connection is reliable, mounting and dismounting are easy, the ballasts can be conveniently sieved and maintained, and all the components are made of glass reinforced plastic sandwich panels. The track bed ice-melting water-draining protection device has the advantages of being high in strength, low in weight, corrosion resistant, waterproof, aging resistant, long in service life, convenient to maintain, and the like. Carbon fiber electric hot plates are arranged in internal paving layers of all the components, a microcomputer is used for controlling temperature, the track bed ice-melting water-draining protection device has the functions of heating and ice melting, and can prevent frost and snow damage. The track bed ice-melting water-draining protection device is suitable for ice melting, water draining and protection of railway coal transportation dust suppression stations and rail track beds where snow hazards easily occur in winter.

Description

technical field [0001] The invention relates to a protective equipment for railway lines, in particular to a protective device for ice melting and drainage of a ballast bed. Background technique [0002] The railway line is composed of subgrade, ballast bed, sleeper, rail and connecting parts. The ballast bed, also known as the ballast bed, usually refers to the ballast (ballast) cushion laid under the sleeper and on the roadbed surface. The main function of the ballast bed is to support the sleeper, and evenly distribute the huge load from the upper part of the sleeper to the roadbed, thereby greatly reducing the deformation of the roadbed to ensure the smooth operation of the train. Ballast is a stone with a diameter of 20~70mm. There are gaps and friction between the stone and the stone, which makes the track have a certain elasticity. This elasticity can not only absorb the impact and vibration of the rolling stock, but also improve the rolling stock and rail. The work...
