Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the utility model provides an adopt progressive mode to write.

As shown in fig. 1 to 2, the pushing roller of the present invention includes a base 1, a rotating shaft 2 and a roller 3; a rotating shaft 2 is fixedly arranged on the base 1; the roller 3 is rotatably sleeved on the rotating shaft 2; the bottom of base 1 is equipped with L type spacing fastener 4.

Due to the fact that the structure of the steel rail fastener system is complex, the surface of the sleeper is not flat, the common pushing roller cannot be stably placed on the rail bearing groove, and the pushing requirement of the long steel rail cannot be met. The common rail fastener systems are in a buckle plate type, a spring strip type and the like, the fastener systems are used by pre-installing an embedded iron seat on a sleeper and then installing other components on the embedded iron seat. The utility model provides a propelling movement gyro wheel is equipped with the structural feature of recess on the pre-buried iron seat according to, sets up the spacing fastener 4 of L type in base 1's bottom, makes the spacing fastener 4 of L type can block into in the recess, cooperatees with the pre-buried iron seat, guarantees that the propelling movement gyro wheel can steadily place on the pre-buried iron seat, the utility model provides a propelling movement gyro wheel is particularly useful for pande way series fastener. Due to the fixing effect of the L-shaped limiting fastener 4, in the pushing process, the pushing roller can bear the frictional resistance generated between the steel rail and the roller 3 along the pushing direction, so that the steel rail cannot be turned on one side or fall off, and the smooth pushing of the steel rail is ensured. In addition, because the L-shaped limiting fastener 4 is in plug connection with the embedded iron seat in a matching mode, the pushing roller can be easily taken down from the embedded iron seat along the opposite direction of bending of the L-shaped fastener. And because the roller 3 is rotatably sleeved on the rotating shaft 2, the pushing work of the steel rail can be completed only by small traction force in the using process. The utility model provides a propelling movement gyro wheel has simple structure, and is small, light in weight, and the big advantage of bearing capacity can combine together with the pre-buried iron seat of track fastener, is particularly useful for Pan to get way series fastener, can effectively solve on the pre-buried iron seat and can not lay the problem that ordinary gyro wheel carried out long rail propelling movement, guarantees simultaneously that propelling movement in-process gyro wheel is stable not have and turns on one's side.

As an embodiment of the present invention, the base 1 of the pushing roller may include a bottom plate 13, a first side plate 11 and a second side plate 12. The first side plate 11 and the second side plate 12 are oppositely arranged and fixed on the bottom plate 13; two ends of the rotating shaft 2 are respectively fixedly connected with the first side plate 11 and the second side plate 12.

It should be noted that, the first side plate 11 and the second side plate 12 are used to fix the rotating shaft 2 on the base 1 and provide a vertical bearing force for pushing the steel rail. The shape and structure of the first side plate 11 and the second side plate 12 may be various, such as rectangular, triangular, semicircular, etc. Meanwhile, the fixed connection mode of the rotating shaft 2 with the first side plate 11 and the second side plate 12 may also be various, such as threaded connection, socket connection, welding, and the like. Moreover, the fixed connection is critical to ensure that the shaft 2 is axially fixed and does not displace axially.

In the production process, the number and the positions of the L-shaped limiting fasteners 4 can be set according to the requirements of actual use. Preferably, the pushing roller is provided with at least two L-shaped limiting fasteners 4, and the connecting line of the L-shaped limiting fasteners 4 is parallel to the rotating shaft. So, just can insert pre-buried iron seat with L type spacing fastener 4 along rail propelling movement direction during the use, make the propelling movement gyro wheel can bear the frictional resistance that produces along the propelling movement direction between rail and the cylinder 3 better, avoid taking place to turn on one's side and drop, guarantee the smooth propelling movement of rail.

Further, the L-shaped limiting fastener 4 and the base 1 can be detachably connected. Thus, the L-shaped limiting fastener 4 can be detached from the roller base 1 in the occasion that the L-shaped limiting fastener 4 is not needed. In addition, in order to prevent the L-shaped stopper 4 from being lost due to improper storage after the L-shaped stopper 4 is removed, the L-shaped stopper 4 may be connected to the base 1 by a connecting member such as a chain.

Further, in order to reduce the frictional resistance between the steel rail and the roller 3 in the pushing process, the roller 3 can be a rolling bearing, wherein the inner ring of the bearing is matched with the rotating shaft 2 to play a supporting role; the outer ring is in contact with the steel rail, rolling bodies are uniformly distributed between the outer ring and the inner ring, and the rolling bodies rotate to play a lubricating role in the pushing process. Therefore, the weight of the steel rail is directly supported by the bearing, the friction coefficient is low, the friction resistance is small, and the pushing work of the steel rail can be completed only by small traction force.

Further, to ensure that the rail always advances along the line extending direction during the pushing process, the middle section of the outer surface of the drum 3 may be recessed to form a rail groove 31. Therefore, when the steel rail is transported, the limiting effect of the rail groove 31 can ensure that the steel rail moves forwards in the rail groove 31, and the transverse displacement cannot occur.

In addition, because the dead weight of rail is big, and the railway construction cycle is long, in order to improve the bearing capacity of propelling movement gyro wheel, prolongs its life, can strengthen through first gusset between first curb plate 11, second curb plate 12 and the bottom plate 13. Preferably, the space between the L-shaped limit fastener 4 and the bottom plate 13 can also be reinforced by a second rib plate.

Meanwhile, in order to facilitate carrying of the push roller, at least one through hole may be formed in the bottom plate 13 of the push roller, so as to reduce the weight of the roller itself.

Further, the base 1 may be made of a thickened steel plate. Wherein the thickness of the steel plate is 10-15mm, preferably 15 mm.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
