Abstract
The invention provides an online detecting method for a brake of a lifting mechanism of a crane. The online detecting method comprises the following steps that: (1) a foundation rack is fixedly mounted on the lateral face of the brake of the lifting mechanism of the crane, wherein a mounting position of the foundation rack is 100mm far from the axis of a push rod of a hydraulic pusher of the brake of the lifting mechanism of the crane and is 30mm far from the outer edge of a triangular connection board of the brake of the lifting mechanism of the crane, and the foundation rack is 50mm higher than a normal position of the brake of the lifting mechanism of the crane; (2) a stroke switch is fixed on the foundation rack; (3) a multi-wire annealed copper wire with a cross section of 1.5 square millimeters is connected with an indicator lamp of a cab of the crane; and (4) if a contact state of the stroke switch and the triangular connection board of the brake of the lifting mechanism of the crane is adjusted, the brake is powered on to drive a contact of the stroke switch to close, and the indicator lamp of the cab is lightened, thereby indicating that the brake normally works, but if the indicator lamp of the cab is not lightened, the abnormality of the brake is indicated.
Description
Technical field
The invention belongs to travelling overhead crane apparatus safe operation field, be specifically related to a kind of crane hoisting mechanism drg online test method.
Background technology
Crane in bridge type is most popular a kind of hoisting crane in the middle of all types of hoisting cranes, the used drg of the lifting mechanism of crane in bridge type is one of three large important components of crane safety production, drg is if there is problem, can cause great personnel and equipment breakdown, therefore extremely important to correct use, inspection, the maintenance of drg.Metallurgical special-purpose crane in bridge type particularly, the reason such as large owing to the work-site noise, that temperature is high, crane structure is huge, operating environment is poor, crane driver is in the manipulating crane operation process, be difficult for finding the strange phenomena of drg appearance, lifting mechanism continues operation in the situation that drg is failure to actuate like this, very easily cause equipment breakdown, even the serious accident that can cause personnel to injure.
Can hoisting crane regular event at the moving device of work schedule, the driver can't see the drg service condition, only depend on driver's micro-judgment to be difficult to guarantee safe, therefore, can find in time that the abnormal condition that drg occurs play vital effect to safety in production.
Summary of the invention
The objective of the invention is in order to find in time whether crane brake works, avoid that the driver does not find that hoisting crane continues operation and causes the equipment breakdown of brake failure and the serious accident of personnel's injury in the situation that crane brake breaks down.
Technical scheme of the present invention:
(1), at foundation frame of crane hoisting mechanism drg side fixed installation; The installation site of foundation frame is apart from 100 millimeters in the hydraulic driver push rod axle center of crane hoisting mechanism drg, apart from 30 millimeters of the triangle connecting plate outer rims of crane hoisting mechanism drg, the aspect ratio crane hoisting mechanism drg normality position of foundation frame is high 50 millimeters;
(2), travel switch is fixed on the foundation frame;
(3), be that the multifibres soft copper wire of 1.5 square millimeters is connected with the crane cabin indicator lamp with the cross section;
(4), adjust the contact condition of travel switch and the triangle connecting plate of crane hoisting mechanism drg, drg gets electric opening and drives that the travel switch closing of contact---the driver's cab indicator lamp is bright, represents that drg is working properly; If indicator lamp does not work, illustrate that drg is unusual.
The crane hoisting mechanism drg in the middle of real work for various reasons, once et out of order makes the drg cisco unity malfunction, the immediately glittering caution of the drg indicator lamp of driver's indoor location, the driver just can find within the very first time, even if when can taking measures, actv. has avoided because all kinds of accidents that the drg malfunction may cause.
The present invention is through repeatedly on probation online, Detection accuracy to crane brake reaches 100%, guaranteed drg failure-free operation from hardware facility, failure-free guarantees for safety, production, cost, consumption etc. bring very, from having guaranteed in essence the safe and reliable of drg, played extraordinary effect
The specific embodiment
1, a foundation frame is installed in crane hoisting mechanism drg side.(can use ∠ 50 section steel manufactures)
2, the installation site is apart from 100 millimeters in crane hoisting mechanism drg hydraulic driver push rod axle center, apart from 30 millimeters of crane hoisting mechanism drg triangle connecting plate outer rims, aspect ratio crane hoisting mechanism drg normality position is high 50 millimeters, is screwed or is welded and fixed.
3, adopt LX2 or LX19 series travel switch, be fixed on the angle steel foundation frame.
4, the multifibres soft copper wire with 1.5 square millimeter cross sections is connected with the driver's cab indicator lamp.(can add the illumination sign loop, adopt the 36V safety voltage)
5, adjust the contact condition of travel switch and crane hoisting mechanism drg triangle connecting plate, require the crane hoisting mechanism drg get electric open drive the travel switch closing of contact, the driver's cab indicator lamp is bright, represents that with this crane hoisting mechanism drg is working properly.If indicator lamp does not work, illustrate that the crane hoisting mechanism drg is unusual.
Illustrate: crane hoisting mechanism drg hydraulic driver push rod, crane hoisting mechanism drg triangle connecting plate, driver's cab all are auxiliary facilities of hoisting crane.
Claims (2)
1. a crane hoisting mechanism drg online test method comprises the steps
(1), at foundation frame of crane hoisting mechanism drg side fixed installation; The installation site of foundation frame is apart from 100 millimeters in the hydraulic driver push rod axle center of crane hoisting mechanism drg, apart from 30 millimeters of the triangle connecting plate outer rims of crane hoisting mechanism drg, the aspect ratio crane hoisting mechanism drg normality position of foundation frame is high 50 millimeters;
(2), travel switch is fixed on the foundation frame;
(3), be that the multifibres soft copper wire of 1.5 square millimeters is connected with the crane cabin indicator lamp with the cross section;
(4), adjust the contact condition of travel switch and the triangle connecting plate of crane hoisting mechanism drg, drg gets electric opening and drives that the travel switch closing of contact---the driver's cab indicator lamp is bright, represents that drg is working properly; If indicator lamp does not work, illustrate that drg is unusual.
2. a kind of crane hoisting mechanism drg online test method according to claim 1 is characterized in that described travel switch is LX2 or LX19 series travel switch.
