Description
Technical field
The present invention relates to a kind of disk type braker, specifically a kind of disk type braker with brake block abrasion and dish spring fatigue detecting function.
Background technique
Disk type braker is widely used in operated hoisting transport driving industry, and the safety protection of equipment is played to vital effect, and for manned equipment, the performance of disk type braker is more regarded as the most important thing.
The performance of disk type braker is mainly reflected in brake block abrasion and tired two aspects of dish spring.Along with the increase of brake block abrasion, the braking torque of disk type braker reduces gradually, and brake block abrasion to a certain extent time, loses braking ability, easily causes the generation of serious accident; In the time that dish spring is tired, brake shoe reduces the positive pressure of brake disc, can produce equally above-mentioned consequence.
For the detection of brake block abrasion in disk type braker and the dish spring fatigue method that all has nothing good at present.Application number is the disk type braker that 200810155643.8 Chinese invention patent discloses a kind of monitoring brake positive pressure, but the disclosed disk type braker of patent needs the special load cell of installing, so just increase the size of break, and also comparatively complicated for maintenance and the replacing of this sensor.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of disk type braker with brake shoe and dish spring measuring ability, reliable, components and parts replacing convenience operates steadily, in the situation that brake dimensions does not increase, effectively detect the fatigue failure situation of brake block abrasion and dish spring, ensure the job security of disk type braker.
To achieve these goals, this disk type braker comprises by bolt and the piston that brake shoe seat is connected, and is arranged on the brake shoe in brake shoe seat, and is fitted in the dish spring on described brake shoe seat;
Described piston connects one end of test rod, and the other end of test rod is fixed with left contact and right contact, and switch I and switch II are installed on the support of lock seat, described left contact and switch I cooperating, described right contact and switch II cooperating; The filler opening A mouth of pressure oil is connected with sensor.
Further, described switch I and switch II are sensitive switch.
Further, described sensor is pressure transmitter.
Compared with prior art, this disk type braker is provided with test rod, left and right contact, switch and sensor, and the combination of left contact and switch I can detect brake block abrasion situation, while may wear to a certain degree, sends signal adjustment or changes brake shoe to control system; The combination of right contact and switch II and sensor can detect the fatigue failure of dish spring, in the time that dish spring loses efficacy, sends sighal replacement dish spring to control system.It is convenient that this disk type braker operates steadily reliably, components and parts are changed, in the situation that brake dimensions does not increase, can effectively detect the fatigue failure situation of brake block abrasion and dish spring, ensure the job security of disk type braker, there is practicability widely.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, this disk type braker comprises the piston 2 being connected with brake shoe seat 7 by bolt 10, is arranged on the brake shoe 8 in brake shoe seat 7, and is fitted in the dish spring 9 on described brake shoe seat 7;
Described piston 2 connects one end of test rod 1, the other end of test rod 1 is fixed with left contact 3 and right contact 6, switch I 4 and switch II 5 are installed, described left contact 3 and switch I 4 cooperatings, described right contact 6 and switch II 5 cooperatings on the support of lock seat 11; The filler opening A mouth of pressure oil is connected with sensor 12.
Further, described switch I 4 and switch II 5 are sensitive switch, and the contact spacing of sensitive switch is less, has higher sensitivity, can effectively improve sensitivity and the accuracy of the fatigue failure situation that detects brake block abrasion and dish spring.
Further, described sensor 12 is pressure transmitter, pressure transmitter can be accepted pressure variations, after sensing conversion, pressure variety is converted to standard output signals by a certain percentage, the physical pressure parameter that load cell is experienced is transformed into the electrical signal of standard, to supply with, the secondary meters such as indicator alarm, recorder, regulator are measured, instruction and procedure regulation, can effectively improve this disk type braker for the performance of fatigue failure situation that detects brake block abrasion and dish spring.
This disk type braker is as follows for detection of the working principle of brake block abrasion and dish spring fatigue failure situation function:
When braking, the brake shoe 8 that is installed on brake shoe seat 7 presses to brake disc under the active force of dish spring 9, and piston 2 moves thereupon simultaneously, and test rod 1 is along with piston 2 moves.In the time that brake shoe 8 may wear to a certain degree, the distance that test rod 1 moves with piston 2 increases, and now left contact 3 will be near switch I 4, in the time of left contact 3 touch switch I 4, the wearing and tearing that brake shoe 8 is described have reached specified value, should adjust in time break or change brake shoe 8.
Principle of Process for dish spring fatigue detecting is, after new break Installation and Debugging, open break, pass into pressure oil from filler opening A mouth, now piston 2 moves to left, and drives brake shoe seat 7 compact disc springs 9 to move to left, and test rod 1 is along with piston 2 moves to left simultaneously, in the time being fixed on the right contact 6 touch switch II 5 of test rod 1, write down the now force value of sensor 12.After bringing into use, repeat aforesaid operations once every one period, if the force value of sensor 12 is less than 20% of primary detection value, think that dish spring 9 is tired, should adopt remedial measures in time or directly change.
It is convenient that this disk type braker operates steadily reliably, components and parts are changed, in the situation that brake dimensions does not increase, can effectively detect the fatigue failure situation of brake block abrasion and dish spring, ensure the job security of disk type braker, there is practicability widely.
