Abstract
The utility model discloses a roller wheel slide plate. The roller wheel slide plate comprises a bottom plate, a roller wheel carrier, a roller wheel component, an eccentric roll shaft, a base plate, a roller wheel adjusting device and switch tie bolts; an eccentric hole is formed in the bottom plate, the bottom plate is connected with a switch tie through the switch tie bolts, the roller wheel carrier is mounted on the bottom plate, the roller wheel component is sleeved on the eccentric roll shaft, the eccentric roll shaft is mounted in the roller wheel carrier, the base plate is mounted between the roller wheel carrier and the bottom plate, and the roller wheel adjusting device is mounted on one side of the roller wheel carrier. According to the roller wheel slide plate, the roller wheel component is mounted on the slide plate to finish the switching of a switch rail in a rolling manner, the power between wheels and the switch rail and the power between the switch rail and the slide plate are effectively reduced, the working condition of a turnout junction is optimized, and the running safety of a train is improved.
Description
Technical field
The utility model relates to railway drag reduction technology field, is specially a kind of roller slide plate.
Background technology
In recent years, along with China's economic construction develop rapidly, railway transportation, as the main artery of national economy, is being undertaken shipping and the large important transportation task of passenger traffic two.After railway the sixth speed-up, building of high-speed railway particularly, train speed is greatly enhanced, the importance that it is unusual that the safety of thing followed railway transportation just seems, track switch, as one of vitals of railroad track, is being accepted the task of train transition; Slide plate is as the strength member of track switch, within the scope of whole length of switch rail support tongue, withhold stock rail, traditional track switch adopts slip slide plate, in a changing points process, one side tongue moves on to closely connected position by scolding to off normal, and opposite side tongue is moved to scold by closely connected position and offs normal simultaneously; Yet the raising along with train speed, the number of track switch increases gradually, the length of tongue and weight increase, frictional force increases thereupon, easily there is the opening of a point, dynamic action between aggravation wheel and tongue and tongue and slide plate, has worsened the condition of work of track switch, the traffic safety that also jeopardizes train when serious.
Utility model content
The technical problem that the utility model solves is to provide a kind of roller slide plate, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Roller slide plate, comprises base plate, turning rolls, roll wheel assembly, eccentric roll shaft, backing plate, rolling wheel regulator and turnout sleeper bolt; Wherein, be provided with eccentric orfice on base plate, base plate is connected with switch tie by turnout sleeper bolt, turning rolls is arranged on base plate, and roll wheel assembly is sleeved on eccentric roll shaft, and eccentric roll shaft is arranged in turning rolls, backing plate is arranged between turning rolls and base plate, and rolling wheel regulator is arranged on turning rolls one side.
In the utility model, roll wheel assembly comprises upper roller and bottom roller.
In the utility model, on upper roller and bottom roller, be nested with elastomeric material, can reduce the frictional resistance between wheel and tongue and tongue and slide plate.
In the utility model, between roll wheel assembly and eccentric roll shaft, be provided with axle sleeve, upper roller and bottom roller and axle sleeve are matched in clearance, upper roller and bottom roller rotate around axle sleeve.
In the utility model, on base plate, be provided with eccentric orfice, eccentric orfice is used for installing composite buffering eccentric cover, and turnout sleeper bolt is surrounded by composite buffering eccentric cover, and buffering is passed to the lateral force of turnout sleeper bolt by backing plate, be conducive to reduce the height of Lateral Force point.
In the utility model, the vertical height of diverse location place roller regulates by rolling wheel regulator, is seated on base plate when tongue is opened, and bears train load; Scold while changing from stock rail, the tongue flange of rail is climbed up roll wheel assembly, with rolling form, completes conversion, the state tongue of pulling open is seated on roller, can effectively reduce the power between wheel and tongue and tongue and slide plate, optimize the condition of work of track switch, improve the traffic safety of train.
Beneficial effect: the utility model is provided with roll wheel assembly on slide plate, completes tongue conversion with rolling form, effectively reduces the power between wheel and tongue and tongue and slide plate, optimizes the condition of work of track switch, improves the traffic safety of train.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the roller slide plate of Fig. 1, comprise base plate 1, turning rolls 2, roll wheel assembly, eccentric roll shaft 3, backing plate, rolling wheel regulator 4 and turnout sleeper bolt; Wherein, on base plate 1, be provided with eccentric orfice 5, base plate 1 is connected with switch tie by turnout sleeper bolt, turning rolls 2 is arranged on base plate 1, roll wheel assembly is sleeved on eccentric roll shaft 3, eccentric roll shaft 3 is arranged in turning rolls 2, and backing plate is arranged between turning rolls 2 and base plate 1, and rolling wheel regulator 4 is arranged on turning rolls 2 one sides.
In the present embodiment, roll wheel assembly comprises upper roller 6 and bottom roller 7.
In the present embodiment, on upper roller 6 and bottom roller 7, be nested with elastomeric material, can reduce the frictional resistance between wheel and tongue and tongue and slide plate.
In the present embodiment, between roll wheel assembly and eccentric roll shaft 3, be provided with axle sleeve 8, upper roller 6 and bottom roller 7 are matched in clearance with axle sleeve 8, and upper roller 6 and bottom roller 7 rotate around axle sleeve 8.
In the present embodiment, be provided with eccentric orfice 5 on base plate 1, eccentric orfice 5 is for composite buffering eccentric cover is installed, and turnout sleeper bolt is surrounded by composite buffering eccentric cover, and buffering is passed to the lateral force of turnout sleeper bolt by backing plate, be conducive to reduce the height of Lateral Force point.
In the present embodiment, the vertical height of diverse location place roller regulates by rolling wheel regulator 4, is seated on base plate 1 when tongue is opened, and bears train load; Scold while changing from stock rail, the tongue flange of rail is climbed up roll wheel assembly, with rolling form, completes conversion, the state tongue of pulling open is seated in roller set, can effectively reduce the power between wheel and tongue and tongue and slide plate, optimize the condition of work of track switch, improve the traffic safety of train.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
