Description

Railway screen scarifier chassis auxiliary device

Technical Field

The utility model belongs to the field of railway cleaning, and particularly relates to a railway screen scarifier chassis auxiliary device.

Background

The railway line has great influence on the state and performance of the line through long-term use, dirt on the ballast bed and broken ballast. The dirty ballast firstly causes the ballast bed to lose elasticity and drainage performance, and then causes the whole ballast bed to be hardened. The "hardening" of the ballast bed can have an impact on train transportation safety. Therefore, when the degree of the uncleanness of the crushed stone or pebble ballast bed exceeds 25% by weight, screening must be performed. At present, a way of treating the slab phenomenon is to use a railway screen scarifier to drive on a railway to clean broken stone and pebbles under a sleeper, backfill new railway ballast stones under the sleeper by the sleeper after cleaning, and then manually stamp to stabilize the line after cleaning.

At present, the railway screen scarifier can directly travel on the railway, so that the crawler belt on the railway screen scarifier is in direct contact with the rail to clean, the contact surface of the crawler belt and the rail is small, the crawler belt and the rail are made of iron materials, friction force between the crawler belt and the rail is small, and side thrust can be generated when the railway screen scarifier cleans broken stones and pebbles, so that the road screen scarifier can deviate from the direction and even fall off on the rail after long-time screening, and time is wasted and the railway screen scarifier is restarted to the rail in the follow-up process, so that the working efficiency is reduced.

Detailed Description

For a better understanding of the objects, structure and function of the present utility model, a chassis assist device for a railway screen scarifier according to the present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, the railway screen scarifier chassis auxiliary device comprises a screen scarifier composed of a chassis 2, power devices 3, tracks 4 and a screen scarifier main body 1, wherein the power devices 3 for driving the screen scarifier are arranged on two sides of the chassis 2, the tracks 4 are arranged on each power device 3, the power devices 3 drive the tracks 4 to rotate so as to enable the screen scarifier to move, the screen scarifier main body 1 is arranged on the chassis 2, and stone pebbles below a sleeper can be cleaned through a ballast cleaning device on the screen scarifier main body 1.

Preferably, the chassis 2 is symmetrically provided with guide assemblies 5 for guiding the screening machine, and the guide assemblies 5 can assist the railway screening machine to work for a long time when moving on the rail, so that the screening machine is prevented from deviating from the rail and falling off, the purpose of protecting the rail from being damaged by the track 4 of the screening machine is achieved, and the service life of the rail is prolonged.

Specifically, each guide assembly 5 is disposed at both sides of the front end and the rear end of the traveling direction of the screen scarifier so as to assist in the traveling direction of the screen scarifier when the screen scarifier travels on the rail. As shown in fig. 2 and 3, each guide assembly 5 includes a support column 501 symmetrically disposed on one side of the chassis 2, and a U-shaped groove is formed at a free end of each support column 501, receiving posts 502 are rotatably disposed in the U-shaped grooves at the free ends of the two support columns 501, the free ends of the two receiving posts 502 are connected by a connecting plate 503, rail wheels 504 are rotatably disposed at two ends of the connecting plate 503, a rim is disposed on each rail wheel 504, the distance between the two rail wheels 504 on the same connecting plate 503 is the same as the distance between the two rails on the same railway, and the two rims are disposed on inner sides of the corresponding rails, so that the rim can limit the screen cleaner when moving on the rails. Meanwhile, a control part is also provided between the chassis 2 and the connection plate 503. The control part can control the lifting and the lowering of the connecting plate 503 and the rail wheel 504 on the connecting plate relative to the supporting column 501, so as to facilitate the later use of the rail wheel 504.

As shown in fig. 3, the control part comprises a traction frame 505 arranged on one side of the chassis 2, a hydraulic cylinder 506 is rotatably arranged on the traction frame 505, the hydraulic cylinder 506 is connected with a hydraulic pump on the screen scarifier through a connecting pipe, and one end of the hydraulic cylinder 506 opposite to the traction frame 505 is rotatably arranged with the connecting plate 503. When the screen scarifier runs on the rail, a hydraulic pump is started, the hydraulic pump drives a hydraulic cylinder 506 to work, the hydraulic cylinder 506 pushes a connecting plate 503 to rotate in the middle of the connecting point of the supporting column 502 and the supporting column 501, so that the connecting plate 503 can drive a rail wheel 504 to descend, and the rail wheel 504 and the rail can be normally used. Thus, when the screen cleaner runs on the rail, the rail wheels 504 can play a role in guiding the screen cleaner, so that the problem that the rail is damaged due to the fact that the screen cleaner falls off the rail when the screen cleaner runs on the rail and works is prevented.

In order to prevent the crawler belt 4 from damaging the top surface of the rail when the crawler belt 4 runs on the rail, rubber pads 7 are arranged on the outer sides of the crawler plates on the crawler belt 4, and the rubber pads 7 can slow down the direct contact between the crawler belt 4 and the rail, so that the effect of protecting the rail is achieved.

As another preferable aspect, the cleaning plates 6 are symmetrically provided at one end of each of the connection plates 503 opposite to the control portion. The connecting plate 503 drives the rail wheel 504 to descend under the action of the control part to match with the rail, at this time, the free end of the cleaning plate 6 contacts with the rail joint top surface correspondingly arranged, and the cleaning plate 6 correspondingly arranged is positioned at the outer side of the connecting plate 503. When the screen scarifier runs on the rail, the cleaning plate 6 can clean stones or other obstacles remained on the top surface of the rail, so that the damage to the rail caused by direct rolling of the screen scarifier on the stones or the obstacles is prevented, and the service life of the rail is influenced.

Specifically, the cleaning plate 6 is made of rubber, the cleaning plate 6 made of rubber can deform, and the cleaning plate is in contact with a rail and is more fit with the rail, so that the cleaning plate is low in cost and convenient to use.

The using method comprises the following steps: the screen cleaning machine is driven onto rails, then a hydraulic pump is started, the hydraulic pump drives a hydraulic cylinder 506 to work, the hydraulic cylinder 506 pushes a connecting plate 503 and a rail wheel 504 on the connecting plate to rotate downwards around a connecting point of a supporting column 502 and the supporting column 501 as a center, the connecting plate rotates until the rail wheel 504 is matched with the rails, then the screen cleaning machine is started to clean broken stone pebbles under the sleeper, and after cleaning is finished, the hydraulic pump is started again to drive the connecting plate 503 and the rail wheel 504 to rotate upwards around the connecting point of the supporting column 502 and the supporting column 501 as a center to an initial position.

It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof.
