Industrial-mineral electric locomotive anti-lock electromagnetic braking device

Abstract

The invention relates to an industrial-mineral electric locomotive anti-lock electromagnetic braking device. The device mainly overcomes the defects that as the existing pneumatic or handwheel mechanisms brake and respond slowly, the braking distance is long, the braking performance is poor, the brake block is easy to wear, etc. The device also solves the technical problems that owning to large braking force or mechanical reasons, the locomotive wheels lock so as to cause derailment phenomenon and the like. The keys of the technical scheme of the invention are as follows: a brake disc spring and an electromagnetic iron core are sleeved in a cylinder body, a brake pull rod penetrates through the brake disc spring and electromagnetic iron core in the cylinder body, brake levers are sleeved on the two ends of the brake pull rod, the lower ends of the brake levers are hinged with a braking device frame; clamping plate brake bodies are arranged on the two sides of a brake disc correspondingly, the clamping plate brake bodies are hinged on the two ends of the braking device frame and fit with the brake levers in a linkage manner; and a control cable is connected with the electromagnetic iron core, and an electromagnetic pressure switch is arranged on the control cable. The anti-lock electromagnetic braking device can be widely used for the brake control of the industrial and mineral electric locomotive.

Description

technical field [0001] The invention relates to a brake device, in particular to an anti-lock brake device suitable for industrial and mining electric locomotives. Background technique [0002] At present, the braking devices used on industrial and mining electric locomotives generally use air pressure or hand wheel machinery for braking, but they respond slowly, resulting in long braking distances, poor braking performance, and the disadvantages of easy wear and tear of brake shoes; At the same time, the wheels of the locomotive may be locked due to excessive braking force or mechanical reasons, resulting in derailment. Contents of the invention [0003] The object of the present invention is to provide an anti-lock electromagnetic braking device for industrial and mining electric locomotives with fast braking response, good braking effect and anti-lock function. [0004] The technical solution adopted by the present invention to solve its technical problems is: it inclu...
