Description

Technical Field

[0001] The utility model relates to auxiliary equipment for railways, in particular to a novel buffer sliding car stopper. Background Art

[0002] A train blocker is a safety device installed at the end of a railway track to provide an effective barrier to protect personnel and equipment in the event of a train runaway or other emergency.

[0003] Existing car stops usually use hydraulic or spring buffer structures. When the train approaches the car stopper, after contacting the front end of the buffer head, the hydraulic structure and / or the spring group's buffering effect absorbs the train's kinetic energy, causing the train to gradually slow down and eventually stop. However, for car stops using a hydraulic structure, when the buffer head is impacted by a train, it will cause a certain degree of oil leakage. When a single spring structure is used in the buffer cylinder, a large torque will be generated in the radial direction when the spring is compressed, which will affect the movement of the plunger. During the use of the damper assembly, the friction force is reduced due to friction loss, resulting in a decrease in the braking effect. Utility Model Content

[0004] The utility model aims to provide a novel buffer sliding car stopper, which fundamentally solves the above problems and has the advantages of simple and compact structure, convenient use, stable buffering, etc.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the new buffer sliding car stopper comprises a spring buffer assembly with a buffer head assembly at the front end, an arm frame assembly slidably supported between the rails through the damper assembly, and a balancing chassis assembly, and its technical highlights are: the spring buffer assembly comprises a cylinder body with a flange fixed at the front end, a plunger sleeved in the cylinder body and sealed at the front end by a front cover, and a pair of buffer springs respectively limited in the cavities of the plunger and the cylinder body; the two buffer springs have opposite spiral directions, and their outer sides are respectively limited by the front spring seat and the rear spring seat, and their inner sides are limited by a spring positioning ring; a hollow spring sleeve is fixed on the rear spring seat, and a spring rod that can slide along the spring sleeve is fixed on the front spring seat, and both the spring rod and the spring sleeve are located in the buffer spring.

[0006] Furthermore, the buffer head assembly includes a buffer seat and a buffer rubber plate fixed at the front end of the buffer seat.

[0007] Furthermore, the damper assembly includes a pair of damper shells arranged on both sides of the rail and fastened by a plurality of fastening bolt assemblies, a spring plate and a friction seat arranged from top to bottom and limited between the damper shell and the rail, a plurality of pressure nuts limited at the top of the damper shell along the direction of the rail, and a pressure bolt screwed on the pressure nut for fastening the spring plate.

[0008] Furthermore, a signboard is fixed on the buffer seat above the buffer seat.

[0009] Furthermore, the support arm frame assembly includes a pair of base frame connecting plates respectively arranged on the steel rails on both sides, and each arm plate located between the corresponding side base frame connecting plates; the bottom of the support arm plate is fixed on the damper assembly, and the front and rear sides thereof are respectively provided with a front rib plate and a rear rib plate, and the top of the support arm plate is provided with an upper connecting plate for connecting the spring buffer assembly.

[0010] Furthermore, the balancing chassis assembly includes a frame structure consisting of an X-shaped bracket, chassis frames located at the front and rear sides, and a plurality of end plates, and the end plates are fixed to the chassis connecting plates through chassis pins.

[0011] The beneficial effects of the utility model are as follows: in terms of the overall technical solution, the oil cylinder structure on the top of the original buffer is omitted, thereby avoiding the defect of oil leakage and making the overall structure more compact.

[0012] In the specific scheme, the damper assembly limits the spring plate and the friction seat on the rail by means of a pressure nut fixed on the damper shell and a pressure bolt with adjustable pressure screwed on the pressure nut, and then the damper shell is tightened in the horizontal direction by a number of fastening bolt assemblies. By adjusting the pressure of the pressure bolt during installation, the problem of insufficient friction of the damper assembly caused by different degrees of wear on the rail surface and uneven rail surface can be avoided.

[0013] The spring buffer assembly mainly uses a pair of buffer springs with opposite spiral directions connected by a spring positioning ring as a buffer energy absorption structure, so that the pair of buffer springs provide opposite rotational forces that can offset each other after compression, thereby ensuring the operating stability of the plunger.

[0014] In summary, the utility model has the advantages of simple and compact structure, convenient use, stable buffering, etc. BRIEF DESCRIPTION OF THE DRAWINGS
