Abstract
A crown block brake device belongs to a crown block control part, and comprises a hydraulic electromagnet, a lever and a brake arm, wherein the lever is connected with the brake arm through a pin shaft, a spring frame is arranged on the brake arm, tiles are arranged on the brake arm, and a brake wheel is arranged between the tiles. The crown block brake device is characterized in that a limit switch is arranged on the lever, and the limit switch is connected with a signal lamp. As the limit switch is arranged on the lever, when the brake moves, the limit switch is jacked by a swing arm, a contact point of the limit switch is closed, a power supply is conducted, and a signal lamp flashes. Limit switches of four brakes of a crown block are connected in series to form a group of signals, and when one of the limit switches goes wrong and does not take effect, the signal lamp does not flash. During operation process, a driver can directly find and handle the failure of the brake in time, thereby avoiding the accidents that a motor is burnt out, and a resistor is burnt out.
Description
Technical field:
The utility model belongs to the overhead traveling crane function unit, is specifically related to a kind of day vehicle brake.
Background technology
Because the overhead traveling crane operation is frequent, driver's operating experience and unusual judgement are irregular, owing to there is not the measure of brake monitoring device fault, brake troubles can not in time be found by the driver, can not get corresponding processing, causes motor or resistor scaling loss at last.
Summary of the invention
The purpose of this utility model just provides and can make the driver in time find a kind of day vehicle brake that drg damages.
The utility model comprises hydraulic electromagnet, lever, brake control lever, and lever is connected with brake control lever by bearing pin, and brake control lever is provided with spring frame, brake control lever is provided with tile fragment, be provided with brake wheel between the tile fragment, it is characterized in that lever is provided with limit switch, limit switch connects signal lamp.
The limit switch that is provided with on the lever of the present utility model, in drg when action,, the limit switch rocking arm is by jack-up, the limit switch closing of contact, power turn-on, signal lamp flicker.The limit switch of four drgs of overhead traveling crane is composed in series one group of signal, an et out of order is wherein arranged, inoperative, signal lamp does not just glimmer.In operating process, the driver can in time find brake troubles intuitively and in time handle, thereby avoid motor or resistor by the accident of scaling loss.
