Description
Technical field
The utility model relates to the disc-brake that a kind of gig uses, and relates in particular to a kind of real-time monitoring disc-brake with pressure sensor.
Background technology
Disc-brake is the hydraulic actuator that is applied to the mine hoist brake system, disc-brake in the prior art is divided into two kinds of forward type cylinder apparatus and rear-mounted cylinder apparatus, the easy build-up of pressure oil seepage of forward type cylinder apparatus is to brake disc, cause friction coefficient reduction between brake shoe and the brake disc, thereby influence lock torque, safety misadventure takes place.And existing disc-brake positive-pressure detection means mainly convert by detecting oil pressure value, but because of there is loss in oil circuit, the friction drag of sealing part, the oil temperature changes series of factors such as causing the viscosity variation and causes the positive pressure and the actual positive pressure that calculate that gap is greatly arranged, precision out of reach operating needs, the positive pressure if the deflection of employing detection dish spring converts, then because of after using a period of time, dish spring rigidity changes, the positive pressure that converts out is greater than the situation of actual positive pressure, cause the enough illusions of positive pressure, braking force is under the situation that does not satisfy the rules requirement, and there is very big potential safety hazard in the use of gig.
The utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, a kind of real-time monitoring disc-brake with pressure sensor is provided, solve in the present technology disc-brake positive pressure and measure inaccurate problem, by the positive pressure of linear direction between direct detection brake shoe and the oil cylinder and monitoring in real time, reduce the disturbing factor in detecting, thereby accurately measure positive pressure.
For solving above technical matters, the technical solution of the utility model is:
A kind of real-time monitoring disc-brake with pressure sensor, comprise brake shoe, cylindrical shell, the braking body, pressure sensor, dish spring orienting sleeve, the oil cylinder part, the disk spring group, link gear, the pressing plate of described brake shoe by both sides is installed in and becomes a rigid body on the cylindrical shell, the disk spring group is installed in dish spring orienting sleeve inner close fitting oil cylinder part bottom, dish spring orienting sleeve partly drives sliding sleeve by oil cylinder can do the piston motion in the braking body, the bottom of dish spring orienting sleeve is connected with the bottom of cylindrical shell by link gear, clamping pressure sensor between dish spring orienting sleeve top and the cylindrical shell top is realized the real-time monitoring of positive pressure.Link gear can be synchronized with the movement cylindrical shell and dish spring orienting sleeve, and can make both separately, thereby can make the pressure between cylindrical shell and the dish spring orienting sleeve change to maximum from 0, installs the positive pressure variation that the upward pressure sensor then can detect disk brake again additional.
Further, described link gear comprises shaft shoulder bolt, spring washer and saucer spring, and shaft shoulder bolt passes the circular hole that dish spring orienting sleeve bottom is reserved, and is connected by screw thread and cylindrical shell, it is locking to install spring washer additional, and the saucer spring is placed on the shaft shoulder bolt between cylindrical shell and dish spring orienting sleeve.Shaft shoulder bolt shaft shoulder guiding, saucer spring force overcome friction flicks, and shaft shoulder bolt thread pulling force retracts cylindrical shell and brake shoe, and then realizes linking and flicking.Work as glancing impact, dish spring orienting sleeve is because the effect of disk spring group is pushed the application of force to cylindrical shell, the elastic element deformation in compression, and dish spring orienting sleeve affacts on the pressure sensor the squeese pressure of cylindrical shell, thereby can detect the positive pressure of this moment; When declutching, dish spring orienting sleeve is owing to the tension of oil cylinder moves right, elastic element discharges elastic force, dish spring orienting sleeve is separated with cylindrical shell, the detected positive pressure of pressure sensor this moment is 0, cylindrical shell declutches thereby realized linking because the screw thread pulling force of shaft shoulder bolt is synchronous and dish spring orienting sleeve moves right simultaneously.
Further, dish spring orienting sleeve is captiveed joint with the disk of oil cylinder part by attachment bolt, is synchronized with the movement thereby disk drives dish spring orienting sleeve with the piston axial motion.
Further, described disk spring group is made up of the involutory combination of disk spring.
Further, in the described oil cylinder part, piston is connected with disk by piston guide rod, and the end face that contacts of piston guide rod and piston all adopts spherical structure, by the spherical aligning effect, guarantees stressed all the time on same straight line.
Further, install nylon jacket additional between described piston guide rod and the piston, adopt interference fit between piston guide rod and the nylon jacket, nylon jacket is fixed on the piston by holding screw, prevents that piston guide rod from getting loose.
Compared with prior art, the utility model advantage is:
The real-time monitoring disc-brake of band pressure sensor described in the utility model adopts the installing pressure sensor, directly detect the positive pressure of linear direction between brake shoe and the oil cylinder, reduced the disturbing factor in detecting, realize maximum positive voltage power, minimum positive pressure, the monitoring of two stage braking positive pressure, and the real-time monitoring of the variation of the pressure in the whole process; The link gear of dish spring orienting sleeve between cylindrical shell can make the brake shoe seat move along with cylindrical shell and be separable, both realized that brake shoe along with the function that piston motion reaches braking and declutches, can carry out the test of positive pressure again; Piston guide rod contacts end face and all adopts spherical structure with piston, spherical structure plays the aligning effect, has guaranteed piston in crank motion, and is stressed all the time on same straight line, guarantees the synchronism that piston moves, and avoids the generation of stuck phenomenon; And the utility model fitted position is little, and easily maintenance improves safety in utilization.
