Abstract
The invention discloses a real-time detection and protection device for brake shoes and a disc spring of a disc brake, which mainly comprises brake shoes, a cylinder, a bracket, a disc-shape spring, an end cap, a piston and an adjusting bolt, wherein a central part of the end cap is provided with a central hole and a linear displacement sensor through the central hole, a measuring rod of the linear displacement sensor passes through a through hole to be pressed against the adjusting bolt of the disc-shaped brake, and a signal line of the linear displacement sensor is connected with a programmable controller. The device realizes the real-time detection of the clearance between brake shoes, the wear of the brake shoes and the fatigue of the disc spring, and is convenient in operation and high in reliability and anti-interference capability.
Description
Technical field
The present invention relates to the lift in the mine hoisting transportation, relate in particular to lift braking device.
Background technique
In the component of mining hoist, disc-brake is one of important safety parts of lift braking system, disc-brake also is the actuator of braking system simultaneously, mainly form by brake shoe 1, cylindrical shell 2, support 3, belleville spring 4, end cap 5, piston 6 and adjustment bolt 7, the pressure that it directly produces brake disc, form required braking moment by the frictional force between brake disc and brake shoe, finish the work braking and safety brake.At present for effective in order to guarantee braking; on disc-brake, assemble position limit switch; protect by detecting brake clearance, this protective gear can't realize whether fatigue is carried out real-time online detection protection to disc-brake brake clearance, brake block abrasion and dish spring.
Summary of the invention
The objective of the invention is to design a kind of protective gear that disc-brake brake shoe and dish spring are detected in real time.
Technological scheme is: it mainly is made up of brake shoe, cylindrical shell, support, belleville spring, end cap, piston and adjustment bolt, it is characterized in that, center portion at end cap is processed with center hole, by center hole linear displacement transducer is installed, the measuring rod of linear displacement transducer withstands on the adjustment bolt of disc-brake after passing through hole, and the signaling line of linear displacement transducer connects programmable controller.
Working principle is: when the brake block abrasion gap became big, measuring rod moved vertically with adjusting bolt, and the amount of movement of measuring rod is exactly the gap and the wear extent of brake shoe.And can judge that according to the extending amount of stretch pressure and spring the dish spring is whether tired.Brake clearance during work; flexible and the suffered operating state signals such as pressure of abrasion condition and dish spring are after linear displacement transducer is gathered; send programmable controller to; programmable controller is with running state parameter and parameter is set; send protective signal through after the logical operation; and running state parameter is reflected on the touch screen; the operator can carry out the adjustment and the setting of the Operational Limits of protective gear easily by touch screen; reach normal working; if the extending amount and the non-linear relation of pressure of dish spring; illustrate that the dish spring is tired, should give replacing.
Its good effect is: this disc-brake brake shoe and dish spring detect protective gear in real time; realized whether fatigue detects in real time for brake clearance, brake block abrasion amount and dish spring to disc-brake; adopted programmable controller to carry out logical operation control; the utilization touch screen is set and is shown; has human-computer dialogue; Chinese character and graphic display such as accurately understand, show value is accurate, easy to operate, reliability is high, antijamming capability is strong, the structure circuit is simple at characteristics.
Description of drawings
Fig. 1 is the schematic representation of the embodiment of the invention.
Among the figure: the 1-brake shoe, the 2-cylindrical shell, the 3-support, the 4-belleville spring, the 5-end cap, the 6-piston, 7-adjusts bolt, 8-measuring rod, 9-bonnet, 10-linear displacement transducer, 11-programmable controller.
Embodiment
Embodiments of the invention are described below with reference to the accompanying drawings.
Disc-brake structure of the present invention mainly is made up of brake shoe 1, cylindrical shell 2, support 3, belleville spring 4, end cap 5, piston 6 and adjustment bolt 7, center portion at end cap 5 is processed with center hole, linear displacement transducer 10 is installed on the bonnet with holes 9, bonnet 9 usefulness nuts are fixed on the end cap 5, measuring rod 8 passes to withstand on behind the center hole of end cap 5 and adjusts on the bolt 7, and the signaling line of linear displacement transducer 10 connects programmable controller 11.Linear displacement transducer 10 cover internal orifice dimensions and measuring rod 8 carry out tolerance fit, have guaranteed can be free to slide with adjusting bolt 7 when work.
