Abstract

The railway turnout is susceptible to snowing in winter due to gaps, so that the turnout cannot be normally used. At present, snow removing is mainly carried out by manually using wind power equipment and the like to clean accumulated snow in turnouts, time, oil and manpower are consumed, the situation of untimely cleaning also exists, personal safety risks exist, and personal casualty accidents caused by snow removal due to multiple reasons have occurred all the year round. The invention relates to a railway turnout snow protection device, which mainly solves the problem of influence of snowfall on the railway turnout in winter. The invention relates to a snow protection device and a sponge, which are respectively arranged in a close contact area and a non-close contact area of a turnout. The non-close contact area can prevent snow from entering the gap of the turnout through the compressibility of the sponge. The close contact area drives the fixed chain and the chain wheel through the pulling force of a spring in the snow-proof device or the pushing force of the switch rail, and then the cover plate covers the upper end of the gap of the turnout through the connecting rod, so that snow is prevented from entering the gap, and the turnout is ensured to be always in a normal use state.

Description

Snow-proof equipment for railway switch

Technical Field

The invention mainly solves the problem that snow falls in winter in railway departments affects turnouts, and ensures that the turnouts are in a normal use state.

Background

At present, the railway department mainly relies on manpower to adopt wind power equipment to clear snow in turnouts in winter, and the like, so that the time, fuel and manpower are consumed, the condition that the smooth transportation is influenced when the snow is not cleared in time also exists, the personal safety risk also exists in the snow clearing process, and a plurality of personal casualties caused by snow clearing have occurred all the year round.

Disclosure of Invention

The railway turnout is mainly influenced by snow, and accumulated snow enters gaps between the switch rails and the stock rails to form snow blocks to be clamped among various stock rails, the switch rails, a slide plate and other equipment, so that the stock rails and the switch rails are not closely attached, and the turnout is in an unusable state. The gap between the switch rail and stock rail of the turnout has two states of separation and closure, wherein the stock rail and the switch rail can be divided into two sections of close contact and non-close contact when closed. The invention relates to a snow protection device and a sponge which are respectively arranged on a close-contact section and a non-close-contact section of a turnout. No matter the turnout is in a separated or folded state, the sponge of the non-close section can play a role in preventing snow from entering the gap of the turnout due to the compressibility of the sponge. When the turnout is in a closed state, the snow protection device at the close section of the turnout does not play a role, and the cover plate is driven to leave the steel rail by virtue of the tensile force of a spring in the snow protection device. When the turnout is in a separated state, the thrust of the switch rail pushes a fixed chain of the snow-proof device to drive a chain wheel to rotate, the cover plate covers a gap between the stock rail and the switch rail through the connecting rod to prevent snow from entering the gap, and meanwhile, the bent design of the end part of the cover plate does not contact wheels, so that the turnout has no influence on rolling stocks. Therefore, the turnout is ensured to be always in a normal use state, only the turnout needs to be installed before snowing, other snow clearing measures are not needed, a large amount of manpower, fuel and time are saved, and meanwhile, smooth transportation is guaranteed.

Detailed Description

The number of the plastic thin plates (72) is determined according to the length of the close-contact section when the turnout is closed, and the plastic thin plates are inserted into the steel bars (71) to form the cover plate (7). Two or more snow guards (8) are then placed in the turnout in a spaced apart position, i.e. the distance between the ends of the connecting rod (9) is the same as the distance of the curvature of the cover plate (7). Then the snow protection device is fixed on the stock rail (3) through a fixed connecting rod (14) and is fixed on a nearby sleeper (1) through a fixed connecting rod (15), so that the snow protection device (8) is ensured to be firm. Then the cover plate (7) and the connecting rod (9) are connected well through a connecting snap ring (92) and a small spring (95). Then the mounted cover plate (7) is in a state of covering on the stock rail (3) and the switch rail (4), the fixed chain (11) penetrates into the retainer ring (131) and the retainer ring (132), one end of the fixed chain is tightly close to the switch rail (4), and the locking iron (134) is pulled to enable the fixed chain (11) to be meshed with the chain wheel (10). The turnout switch rail (4) is moved to be in a closed state, the cover plate (7) is pulled to a proper position, the fixed chain position clamp (111) penetrates into the position where the fixed chain (11) is closest to the clamp ring (131), and then the two ends of the large spring (12) are connected with the locking iron (134) and the fixed chain position clamp (111). And finishing the arrangement of the snow protection device (8). Then the sponge (6) is placed in the non-close section of the gap between the stock rail (3) and the switch rail (4), and the sponge (5) is fixed outside the tip of the switch rail (4) to prevent snow from entering the gap between the stock rail (3) and the switch rail (4). The whole railway turnout snow protection equipment is installed.

Regardless of the turnout in the opening or closing state, the sponge (6) of the non-close section can play a role in preventing snow from entering the gap of the non-close section of the turnout due to the compressibility of the sponge. The sponge (5) prevents snow from entering the gap between the stock rail (3) and the point rail (4). When the turnout is in a closed state, the fixed chain (11) is pulled back by the pulling force of the large spring (12) in the snow protection device (8) to drive the chain wheel (10) to rotate, and the cover plate (7) is moved to a corresponding position through the continuous rod (9) and does not play a role. When the turnout is in a separated state, the moving force of the switch rail (4) pushes a fixed chain (11) of the snow protection device to drive a chain wheel (10) to rotate, and a cover plate (7) is moved and covers the gap between the stock rail (3) and the switch rail (4) through a continuous rod (9), so that snow is prevented from entering the gap between the stock rail (3) and the switch rail (4), and the turnout is ensured to be in a normal use state all the time.
