Abstract
The invention provides a power brake with a brake shoe gap protecting device, and belongs to the electrical technology field. The power brake structurally comprises a brake shoe and a brake disc installed in the middle of the brake shoe. A capacitance probe is arranged on a brake disc base of the brake disc. The front end of the capacitance probe is right opposite to the outer surface of the brake shoe, the front end of the capacitance probe is perpendicular to the outer surface of the brake shoe, and a gap is formed between the front end of the capacitance probe and the outer surface of the brake shoe. Compared with the prior art, the power brake has the advantages of being reasonable in design, simple in structure, convenient to use and the like, an alarm can be given in time for the abrasion situation, and the potential safety hazards of a lifting mechanism brake system are avoided.
Description
Technical field
The present invention relates to technical field of electricity, specifically a kind of machine lock with watt gap protection device.
Background technology
In brake for elevator system, by the friction between brake shoe and brake disc, realize braking, after long in use, because wearing and tearing cause the less thick of brake shoe, so just, need the wear pattern to brake shoe timely to check, if there is no regular inspection, can there is brake block abrasion and excessively affect braking, braking failure occurs therefrom, cause potential safety hazard.
Summary of the invention
Technical assignment of the present invention is for the deficiencies in the prior art, and a kind of reasonable in design, machine lock with watt gap protection device that result of use is good is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of machine lock with watt gap protection device; comprise brake shoe and brake disc; brake disc is arranged on the centre of brake shoe; on the brake disc seat of brake disc, be provided with capacitance probe; the front end of capacitance probe faces outside face the perpendicular setting of brake shoe, between the front end of capacitance probe and the outside face of brake shoe, is provided with gap.
With a machine lock for watt gap protection device, its capacitance probe is provided with one and corresponding with the outside face upper end of brake shoe.
With a machine lock for watt gap protection device, its capacitance probe is provided with two and corresponding with the outside face upper end of brake shoe respectively.
With a machine lock for watt gap protection device, its brake shoe is provided with two and be separately positioned on the both sides of brake disc, and brake shoe is corresponding with the side of brake disc.
Compared with prior art, the beneficial effect producing is machine lock with watt gap protection device of the present invention:
The features such as that the present invention has is reasonable in design, simple in structure, easy to use, function admirable, practicality, cost is low, can monitor voluntarily the wear condition of brake shoe, can in time wear pattern be given the alarm, and has solved
Brake for elevator security of system hidden danger.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the embodiment of the present invention one;
Accompanying drawing 2 is structural representations of the embodiment of the present invention two.
In figure: 1, brake shoe, 2, brake disc, 3, gap, 4, capacitance probe.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail below.
As shown in Figure 1; machine lock with watt gap protection device of the present invention; its structure comprises brake shoe 1 and brake disc 2; brake disc 2 is arranged on the centre of brake shoe 1; on the brake disc seat of brake disc 2, be provided with capacitance probe 4; capacitance probe 4 is provided with one and corresponding with the outside face upper end of brake shoe 1; the front end of capacitance probe 4 faces outside face the perpendicular setting of brake shoe 1; between the outside face of the front end of capacitance probe 4 and brake shoe 1, be provided with gap 3; brake shoe 1 is provided with two and be separately positioned on the both sides of brake disc 2, and brake shoe 1 is corresponding with the side of brake disc 2.
As shown in Figure 2; machine lock with watt gap protection device of the present invention; its structure comprises brake shoe 1 and brake disc 2; brake disc 2 is arranged on the centre of brake shoe 1; on the brake disc seat of brake disc 2, be provided with capacitance probe 4; capacitance probe 4 is provided with two and corresponding with the outside face upper end of brake shoe 1; the front end of capacitance probe 4 faces outside face the perpendicular setting of brake shoe 1; between the outside face of the front end of capacitance probe 4 and brake shoe 1, be provided with gap 3; brake shoe 1 is provided with two and be separately positioned on the both sides of brake disc 2, and brake shoe 1 is corresponding with the side of brake disc 2.
Capacitance probe is arranged on brake disc seat, be used for surveying the brake shoe back side and probe distance, then numerical value is delivered on an intelligent digital controller.After having debugged gap, according to the degree of wear allowing, set the numerical value on intelligent digital controller, be generally for 200 (comprising original numerical value), like this along with the increasing of the wearing and tearing of brake shoe, the distance that brake shoe extends to brake disc is also strengthening, when exceeding 200, intelligent digital controller is to brake circuit power-off, and gives the alarm.Thereby reached the object of protection.
Its processing and fabricating of machine lock with watt gap protection device of the present invention is simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characterictic described in specification sheets, be those skilled in the art's known technology.
