Abstract
The invention relates to an anti-rebound device for a rail wagon brake system, which comprises an anti-rebound ring, anti-rebound boards, an anti-rebound loop and a spring, wherein the anti-rebound ring is circular and annular, and the side face of the anti-rebound ring is provided with a communicated pin hole; one end of each anti-rebound board is a circular arc concave face, and the other end is in a plane long strip structure; the quantity of the anti-rebound boards is two, the circular arc concave face ends thereof are welded on the outer side face of the anti-rebound ring, the two anti-rebound boards are arranged in parallel, and the longitudinal center line of each anti-rebound board forms an 40-45 DEG included angle with the axis of the pin hole of the anti-rebound ring; and the anti-rebound loop is in a U-shaped structure comprising two straight rod sections and one semicircular section, one end board of the anti-rebound loop is fixed between the two anti-rebound boards, and the other end board is connected with the spring. The anti-rebound device has the advantages of reliable structure and sufficient integral elasticity, so that the conversion between a position G and a position P in a G-P conversion device of the rail wagon brake system is well controlled; the maintenance frequency is reduced, and the maintenance and repair cost is saved; and the anti-rebound device has obvious effect for improving the operation and stopping safety of wagons.
Description
Technical field
The present invention relates to a kind of anti-rebound device for rail wagon brake system, belong to the field of components of a kind of brake system of railway truck.
Background technology
Brake system is one of important component part of railway vehicle, and main effect is that train can be slowed down or parking by operating needs, and in case of emergency guarantees train operation and parking safety.Deceleration and stopping performance is the key issue that guarantees safe train operation, and rail freight generally adopts traditional air brake mode, and its groundwork is to reduce pressure through the train pipe; The car brakeing machine makes the pressure air in the auxiliary reservoir get into brake cylinder; Again through foundation brake rigging, make brake shoe be pressed on the wheel tread or brake lining is pressed on the brake disc, make wheel decelerates; Produce and stop train braking force forward, the purpose that reaches deceleration or stop.Meet the lorry of UIC standard brake system for employing, consider running velocity and stopping distance requirement, in Freight Car Braking System, be provided with the G-P transfer device.The G-P transfer device hangs on the vehicle bottom; Mainly form by parts such as bearing block seat, handle, gear, axles; Realize the conversion of G position and P position through manual control G-P change lever,, guarantee that train stops in the stopping distance of regulation to satisfy the requirement of running velocity and deceleration and stopping performance.When train running speed during smaller or equal to 90km/h, change lever should place the G position; When train running speed during greater than 90km/h, change lever should place the P position.In the truck vehicle operational process, because vibration of vehicle, can cause the redirect of G-P change lever, i.e. the redirect of G position and P position has a strong impact on train parking safety, therefore, prevents that the improper conversion of G position and P position is particularly important in the G-P transfer device.
Summary of the invention
The objective of the invention is in order to ensure railway truck operation and stop safe and reliable a kind of anti-rebound device for rail wagon brake system is provided; This device can not change under the situation of existing rail wagon brake system G-P transfer device guaranteeing, prevents the improper conversion of G position and P position in the G-P transfer device.
The objective of the invention is to have following mode to realize:
The present invention includes anti-jump circle, anti-springboard, anti-jump ring, spring, it is characterized in that: anti-jump circle is an annular arrangement, is provided with the pin-and-hole of connection in its side, and anti-springboard is that an end is the circular arc concave surface, and the other end is the strip shape structure on plane; The quantity of anti-springboard is two, and its circular arc concave ends is welded on the lateral surface of anti-jump circle, and two anti-springboards laterally arrange, and the axis of the pin-and-hole of the longitudinal centerline of anti-springboard and anti-jump circle is the angle of 40-45 degree; Anti-jump ring is that anti-jump ring one end plate is fixed between two anti-springboards by two sections straight bar sections and one section U-shaped structure that semicircular ring bar section connects into, and the other end is connected with spring.
Advantage of the present invention is: reliable in structure, have enough integral, flexibles, and make the better controlled that has been converted to of G position and P position in the rail wagon brake system G-P transfer device, have significant effect to improving train operation with the safety of stopping.Application of the present invention has reduced frequency of maintenance, has avoided repeated labor, has practiced thrift the Maintenance and Repair expense.

The specific embodiment
With reference to accompanying drawing 1,2, the present invention includes anti-jump circle 1, anti-springboard 2, anti-jump ring 3, spring 4, anti-jump circle 1 is an annular arrangement; Be provided with the pin-and-hole 7 of connection in its side; Anti-springboard 2 is that an end is the circular arc concave surface, and the other end is the strip shape structure on plane, is provided with pin-and-hole in flat end; The quantity of anti-springboard is two, and its circular arc concave ends is welded on the lateral surface of anti-jump circle 1, and two anti-springboards 2 laterally arrange, and the axis of the pin-and-hole 7 of the longitudinal centerline of anti-springboard 2 and anti-jump circle is the angle of 40-45 degree, and best angle is 45 to spend; Spring 4 is pressed centre type for the circle shackle; Anti-jump ring 3 is by two sections straight bar sections and one section U-shaped structure that semicircular ring bar section connects into, and anti-jump ring 3 one ends are fixed between two anti-springboards with half light unit pin 5 and spring cotter 6, and the other end is connected with spring 4.
During application, the pin-and-hole 7 of anti-jump circle 1 is installed on the G-P transaxle through the purpose made spring cotter, and accompanying drawing 5 is seen in the installation site, and the A-A among the figure promptly is an accompanying drawing 1 to view, and spring 4 is hung on the truck under-frame.For limiting the position of G-P change lever, anti-bouncing device of the present invention has two end positions, and corresponding G-P transfer device G position and P position are as shown in Figure 3 respectively.When switch handle was in a certain position, anti-bouncing device was in cooresponding end position, and a kind of resistance is provided, and only overcame this resistance, could be with handle wrench to another position.The setting angle that the pin-and-hole of said anti-springboard 2 and anti-jump circle is 7 has determined two end positions of anti-bouncing device, and the specifications parameter of spring 4 and performance have determined to provide the size of resistance.
