Description

railway steel rail diffusing roller

Technical Field

The utility model relates to a rail field of diffusing specifically relates to a railway rail cylinder of diffusing.

Background

The seamless steel rail is a main type rail structure commonly adopted in the current railway, is commonly adopted in railway construction, and has three laying methods of single sleeper, group sleeper and long rail row in conclusion according to the current construction technology for laying the seamless line. The single sleeper laying method cancels the traditional track panel assembly base, long steel rails and sleepers are directly transported to a construction site to be laid, and the comprehensive operation efficiency is high, and the technology is advanced, practical and reliable.

When laying a track, the rails need to be placed on rollers in order to reduce the friction generated during the transportation of the rails. The seamless track diffusion is necessary work for maintenance of the seamless track, and is an effective means for adjusting the locking rail temperature of the seamless track, adjusting the internal stress of the steel rail and preventing rail expansion and rail breakage. In order to reduce the expansion resistance of the steel rail and better achieve the diffusion effect when the steel rail is diffused by the department of industry, long rail bars are placed on a roller every 10m according to the related regulations of railway line repair rules and seamless line laying and maintenance methods (TB/T1998-2007), and the rail bars are assisted to repeatedly hit until rebounding. In the past, a common steel pipe is used as a roller, and the friction force in the process of diffusion is large, so that normal diffusion is influenced.

In addition, the bearing capacity of present diffusing device is generally between 1200 kg/and 3500kg/, and the machineshop car receives the damage very easily after the diffusion cylinder installation, and the same roller bearing of most diffusing devices use, and support through a plurality of bearing frames, make the intensity of roller bearing increase, but if under the more condition of cylinder, need install more bearing frame, make equipment structure complicated, set up the cylinder between the sliding bearing frame, make the friction between cylinder and the bearing frame increase, it is great to cause whole equipment coefficient of friction, the last edge of cylinder fries the upper edge of sliding bearing frame thoroughly, can be by the both sides landing of cylinder during track lateral shifting, cause the injury of equipment and personnel.

Disclosure of Invention

An object of the utility model is to provide a railway rail diffuses cylinder, the load that further dispersion rail produced, and the utility model relates to a railway rail diffuses cylinder's quality is light, makes things convenient for transportation and use in the railway work progress.

The utility model provides a technical scheme that its technical problem adopted is: a railway steel rail diffusion roller comprises a roller, a bearing, a roller seat, a bearing groove cover, a dust cover and an anti-skid support. The bearing is arranged at the two ends of the roller respectively, the bearing is placed in the bearing grooves at the two ends of the roller base, the upper end of each bearing groove is provided with a bearing groove cover, the bearing groove cover is provided with bolt holes, the bearing grooves are connected with the roller base through fastening bolts, and the outer ends of the bearing grooves are provided with dust covers to prevent dust from entering the bearings. When the rail diffuses, antifriction bearing is favorable to reducing frictional force to be equipped with the antiskid support bottom the roller seat, the antiskid supports and deepens the road bed, increases the frictional force between cylinder and the ground, prevents that the rail from removing along with the rail when diffusing the cylinder, has greatly improved the free flexible ability and the effect of diffusing of rail, has further promoted the work efficiency that the rail diffuses.

The utility model discloses following beneficial effect has:

1) The bearings are arranged at the two ends of the roller, so that the friction force in the rolling process is reduced, and the operation efficiency is improved.

2) The bottom of the roller seat adopts an anti-skid supporting structure, so that the friction force of the base is increased, and the roller seat can not move along with the movement of the steel rail.

3) The bearing capacity of the steel rail diffusion roller is improved by the cooperation between the roller and the bearing.

4) The bearing can be replaced in time after being damaged, the service efficiency of the diffusing device is improved, and the cost is reduced.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-4, a railway rail-diffusing roller comprises a roller 2, a bearing 1, a roller base 3, a bearing groove cover 5, a dust cover 6 and an anti-skid support 4. The two ends of the roller 2 are respectively provided with a bearing 1, the bearings 1 are placed in bearing grooves at two ends of the roller base 3, the upper end of each bearing groove is provided with a bearing groove cover 5, the bearing groove cover 5 is provided with a bolt hole 7, the bearing groove cover 5 is connected with the roller base 3 through a fastening bolt, and the outer end of each bearing groove is provided with a dust cover 6. When the rail diffuses, rolling bearing 1 is favorable to reducing frictional force to anti-skidding support 4 that is equipped with in the 3 bottoms of roller seat, anti-skidding support 4 deepens into the road bed, increases the frictional force on roller seat 3 and ground, prevents that roller seat 3 from removing along with the rail when diffusing the rail, has greatly improved the free flexible ability and the stress diffusion effect of rail, has further promoted the work efficiency that the rail diffuses.

The operation process of the railway steel rail diffusion roller comprises the following steps: the railway steel rail diffusion rollers are arranged at intervals of 10 meters, the seamless steel rail is vertically arranged with the rollers 2, the seamless steel rail moves on the rollers 2, and the rollers 2 rotate around the bearings 1 under the action of friction force. Because the bottom of the roller base 3 is provided with the anti-skid support 4, the roller base 3 can not slide along with the movement of the steel rail in the rapid movement process of the steel rail. When the bearing 1 is abraded, the bearing 1 can be taken down from the bearing grooves at the two ends of the roller base 3 and replaced by a new bearing 1, so that the maintenance cost of the steel rail diffusing device is reduced, and the service efficiency of the steel rail diffusing device is improved.
