Description

The claimed invention relates to the infrastructure of railway transport, namely to station equipment for braking, securing and holding trains in order to prevent their unauthorized exit from the receiving-dispatching, sorting, sorting-dispatching tracks of railway stations.

Known brake shoe / 1 /, consisting of a steel runner and a shoe, which is installed by the runner on the rolling surface of the rail, under one or more wheels of the cars, with the aim of braking them, keeping them from spontaneous movement, under the influence of wind load forces, or the longitudinal slope of railway tracks ...

The disadvantage of this device is the limited braking force of the shoe, the need for manual laying of several shoes and the impossibility of automating the process of laying a group of shoes under the wheels of the cars. Unauthorized movement of the car in the presence of a shoe only under one wheel of the wheelset leads to skidding movement of the wheelset and damage to the rolling surface of the opposite wheel with the formation of an unacceptable defect and the need to turn the wheelset.

The prototype of this device is the BISON beam barricade device, patent No. 2674287. The disadvantage of this device is the complexity of the precise positioning of the wheelsets of the car, which is fixed in the ZUBR area of action, in order to ensure a guaranteed effect on two bogies, this is due to the short length of the brake beams. Another disadvantage is that the brake rods are pressed only against the inner surfaces of the wheelsets, the applied pressure on the wheel is directed towards the unpressurization of the wheel center.

The objective of this invention is to simplify the positioning of the fixed car, the possibility of guaranteed impact on the wheelsets of two bogies from two sides - the outer and inner. The absence of dynamic loads and smooth operation will ensure the durability of the device, reduce operating costs and eliminate pressure loads on the wheelsets of the cars being fixed, as well as expand the scope of the device.

The technical result is achieved by the fact that a long running rail is used in the ZUBR weighing machine, made with the possibility of adjustable subsidence, long brake beams attached to levers on both sides of the running rail, a multi-circuit hydraulic system with hydraulic cylinders and an electric hydroelectric station. To implement this invention, the following technical solution is proposed: levers, having a crescent-shaped and in the middle part a flat support platform in contact with a cylindrical support located on the rail base, long brake beams made of rail are attached to the levers, and the levers have hinges connected to the running rail.

Crescent-shaped levers, cylindrical supports, hinges and a hydraulic cylinder, located on one under-rail base, form a pincer-shaped section of the device, which, when the car enters the running rail of the device, acts on both brake tires from both sides of the rail and secures the car with a force proportional to the weight of the fixed car ... The floating coupling of the sickle-shaped levers with the cylindrical supports of the rail base allows the brake beams to adapt to the position of the wheel on the rail and significantly reduce the lateral impact forces on the wheels and bogie of the car, as well as on the articulated joints of the sickle-shaped levers with the running rail, which increases the service life of the metal structure of the retarder and the fixed movable composition, allows you to reduce inertial loads and increase the speed of the fixing device (hereinafter referred to as the device). The crescent shape of the levers and their placement in the under-rail space made it possible to reduce the upper clearance above the level of the rail head of the brake beams to a height of no more than 65 mm, which ensures the unimpeded passage of all types of rolling stock, snow-clearing equipment, machines for the care of the superstructure of the track, which significantly expands the area application of the device.

The under-rail base is bolted to the sleeper bar and occupies one inter-sleep space of the rail and sleeper lattice. The set of the claimed device includes 14 pincer-shaped sections that secure at least two car bogies, as well as a hydraulic system equipped with a pumping station with an electric drive and supply pipelines, and control equipment.

The construction of the device is illustrated by the following graphic materials.

FIG. 1 shows the structure, and FIG. 2 and FIG. 3 diagrams of operation of one pincer-shaped section of the device in decelerated (open) and decelerated (closed) states.

FIG. 1 shows the design of the pincer section of the device. On the under-rail base 1, a controlled hydraulic cylinder 2 is mounted, on the rod of which, by means of a rail pad (not shown in Fig. 2), a running rail 3 is supported. levers 4, while the flat platforms of the levers rest on the cylindrical supports 5 of the base 1. To the levers 4 by means of fastening elements (not shown in Fig. 1) are fixed brake beams 7 made of rolled rail. The under-rail base 1 is bolted to the sleeper bar (not shown in Fig. 1) and occupies one space between the sleeper rails and sleepers. The set of the claimed device includes a number of pincer-shaped sections that provide placement on a running rail and braking of at least two car bogies. At the beginning and end of each running rail, a transition link is installed that provides shockless wheel entry from the station track onto the running rail and exit onto the station track (not shown in Fig. 1).

The device works as follows. Before the train enters the device (Fig. 2, open), the hydraulic cylinders 2 of the hydraulic system raise the level of the rail head (hereinafter - UGR) of the running rail 3 to the UGR of the station track. The linkage system with brake beams 7 made of rolled rail, on the one hand, can swing on the articulated axles 6, fixed on the running rail, on the other hand, it rests on the cylindrical supports 5 of the rail base 1 . When lifting the running rail 3, the hinge axles 6 of the crescent levers 4 rise together with it, and their support pads slide along the corresponding cylindrical supports 5, while the crescent levers 4 rotate and spread the brake beams 7, made of rolled rail, until the opening required for passing wheels of rolling stock, not less than 170 mm. Considering that the width of the carriage wheels is 130 mm, a gap of 40 mm allows the lever system to adapt to the position of the wheel on the rail and to exclude the impact of the brake beam 7 on the braked wheel 8.

After the arrival of the car bogies on the running rails 3 (Fig. 3 closed), the devices in the hydraulic cylinders 2 along operator team remove the oil pressure and the hydraulic cylinder rod ceases to maintain the running rail 3 in a raised state. The running rail 3 under the action of the car's gravity lowers and lowers the axles 4 of the hinges of the sickle-shaped levers 6, which rotate and bring the brake beams 7 from both sides until they stop against the wheel rim 8. The force of the brake beams 7 is proportional to the load from the wheel 8 on the brake rail 3. The braking effect is provided by the force action of the brake beams 3 on the wheels of the braking bogies. To decelerate the car, the hydraulic cylinders 2 raise the running rail 3 to the UGR of the station tracks, the device is ready for a car or a group of carriages.

The set of the manufactured prototype of the device includes 14 pincer-shaped sections that ensure placement on the running rail and braking of at least two car bogies. At the beginning and end of each running rail, a transition link is installed that provides shockless wheel entry from the station track onto the running rail and exit onto the station track.

The height of the brake beams above the level above the rail head (UGR) by less than 65 mm ensures the passage of any rail rolling stock and expands the scope of the device.
