An outer braking device for a double-track vehicle

Abstract

The invention provides an outer side braking brake device for a double-rail vehicle. The outer side braking brake device comprises a braking mechanism, wherein the braking mechanism is symmetrically arranged at the bottom of the two sides of a vehicle body in the length direction of the vehicle body and comprises a casing arranged at the bottom of the vehicle body, an eccentric wheel which is in horizontal arrangement and is opposite to the rail positions is respectively arranged at each of the two ends of the inner side of the casing through rotating shafts in an eccentric way, a through hole relative to the eccentric wheel is formed in the side plate arranged at one side, near a rail, of the casing, the edge of one side, far away from the rail, of each eccentric wheel is provided with a position limiting groove, one end of a position limiting stop block arranged in the casing is arranged in the position limiting groove in a clamping way, the other end of the position limiting stop is fixedly arranged on the side plate arranged at one side, far away from the rail, of the casing, the two ends of a connecting rod arranged in the casing are respectively hinged and connected to one side, near the rail, of the two eccentric wheels, the connecting rod is hinged to one end, of a shifting fork arranged in the casing, the other end of the shifting fork is hinged to the side plate of one side, far away from the rail, of the casing, and the middle part of the shifting fork is hinged and connected to a piston rod of an air cylinder. The outer side braking brake device has the advantages that the structure is simple, the manufacturing cost is low, the braking is reliable, and the positioning is accurate.

Description

[0001] Technical field: [0002] The invention relates to an outer brake device for a double-track vehicle. [0003] Background technique: [0004] At present, the double-rails used in the brick and tile machinery industry generally have no connection between the two rails. Due to the large span and long distance between the two rails, it is inevitable that the two rails will elastically deform outward under heavy loads. A gap must be reserved between the two rails, and a certain gap must be reserved between the additional limit wheel and the rail. During the walking process, the car body is actually swinging left and right, and the walking is unstable and the brakes are not reliable. , there are certain potential safety hazards; at the same time, in terms of braking and braking, there is no effective parking method. Now it is to slow down and stop at the required position. If the speed is too fast, it is impossible to solve the problem of heavy-duty vehicles. Parking inertia,...
