The brake caliper body comprises a first friction block, a second friction block, a piston and an oil inlet. The first friction block is arranged on one side in the brake caliper body, and a cylinder, the piston, the oil inlet and the second friction block are arranged on the other side in the brake caliper body. The lower side of one side of the brake caliper body is connected with the axle through a guide pin, the first friction block and the second friction block on the brake caliper body surround the brake disc, and the brake caliper body can rotate around a shaft relative to the brake disc. The axle is arranged on the middle lower side of the brake disc and connected with a fastening bolt through the shaft of the brake disc. The fastening bolt is used for fastening the brake disc. The rear side of the first friction block is provided with a first displacement sensor, and the rear side of the second friction block is provided with a second displacement sensor. The state detection device has the positive effects that the wear degree of the wind-driven generator brake is measured by the sensors, and an alarm is made once the wear exceeds 2mm. The state detection device has the advantages of simple structure, control flexibility and high reliability.
Description
Technical field
The present invention relates to the electronic instrument technical field, concrete is a kind of aerogenerator braking lock condition checkout gear.
Background technology
Aerogenerator is at present in a kind of generating set of constantly applying, to utilize the wind energy that can constantly regenerate.But; at present in the aerogenerator that uses some deficiency because of designing at protective device; cause equipment to be prone to unusually; if keep in repair untimely; aerogenerator is damaged; shortened its serviceable life greatly, and this has not only influenced applying of aerogenerator, and the cost of wind-power electricity generation is obviously improved.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of aerogenerator braking lock condition checkout gear is provided, especially adapts to small-sized wind power generator is detected, its control is effective, can make the aerogenerator safe operation, make the life-span of equipment obtain prolongation and very easy to use.
For achieving the above object, the technical scheme taked of the present invention is:
A kind of aerogenerator braking lock condition checkout gear, contain brake disc, braking clamp body, friction block, piston, oil-in, guide finger, vehicle bridge, set bolt, displacement transducer and oil cylinder, it is characterized in that, braking clamp body contains first friction block, second friction block, piston and oil-in: the side in braking clamp body is provided with first friction block, opposite side in braking clamp body is provided with oil cylinder and piston, the outside of oil cylinder connects oil-in, and the inboard of piston is provided with second friction block; The below of braking clamp body one side links to each other with vehicle bridge by guide finger, and first friction block and second friction block of braking clamp body inboard surround brake disc, and braking clamp body can be done to move around axle with respect to brake disc; Described vehicle bridge is arranged on the middle below of brake disc, by brake disc the axle link to each other with set bolt, set bolt is used for fixing brake disc.
Rear side at described first friction block is provided with first displacement transducer, is provided with second displacement transducer at the rear side of described second friction block, is used to monitor the wear condition of friction block.
The working condition of aerogenerator braking lock condition checkout gear of the present invention is:
Aerogenerator braking lock condition checkout gear of the present invention is installed on the high speed shaft of aerogenerator, brake disc and high speed shaft are connected together, can clamp brake disc by first friction block and second friction block and produce friction force, thereby realize the safety braking of high speed shaft.
During braking, hydraulic oil enters brake cylinder by oil-in and forms pressure, second friction block that promotes piston and inboard thereof moves inward, press to brake disc, it is more and more littler to make first friction block and second friction block surround the space of brake disc, up to first friction block and the two-way brake disc of clamping of second friction block, realize braking.In braking procedure, friction block and friction block and brake disc rub, As time goes on, first friction block and the second friction block surface potential must wear and tear, monitor the wear condition of first friction block and second friction block with displacement sensor, when wear extent surpasses 2 millimeters, report to the police immediately, the prompting maintenance personal in time changes friction block.
Good effect of the present invention is:
(1) the abrasion signal that utilizes sensor that the aerogenerator of measuring is braked lock is passed to displacement transducer, after being handled by displacement transducer signal is delivered to display and alarm again, reports to the police immediately when the degree of wear surpasses 2 millimeters;
(2) can realize detection, have simple in structure, flexible, the easy to use and reliability advantages of higher of control the small-sized wind power generator running status.
