Description
Technical field
The application belongs to industrial safety break technical field, particularly relates to industrial hydraulic disk brake.
Background technique
On the large lifting equipment of industrial enterprise's application such as current Iron And Steel Plant, shipyard, widely used safety type hydraulic caliper-disc brake is that the power transmission of dependence mechanical structure is to ensure the realization of brake functionality.The safety type hydraulic caliper-disc brake structure of prior art is: friction disc device is linked together by connecting rod, attachment screw and pressure-bearing cover plate.And pressure-bearing cover plate is linked together by screw and setscrew nut.Wherein setscrew nut and piston rod are threaded connection.The braking of break and action of declutching are that the action of piston driving friction disc device is the action of indirect belt movable friction plate device under hydraulic oil and disc spring assembly close.The start-stop of break detects sender by indicator switch, and indicator switch is linked together by welding support and piston rod, indirectly realizes motion detection functionality.The deficiencies in the prior art are; Break realizes more complicated due to mechanical structure braking force, easily causes clamping stagnation, thus affects the normal use of break, even causes serious security incident.Meanwhile, compared with directly realizing the break of braking force structural type, weight is relatively large, in-site installation, inconvenient debugging, and friction plate changes difficulty.
Summary of the invention
The object of this invention is to provide a kind of industrial hydraulic disk brake, the deficiency such as overcome poor structure rigidity, the easy clamping stagnation of force transfer mechanism, the inconvenience of friction lining install and adjust that existing break exists, braking reliability is low.
Technological scheme of the present invention is: industrial hydraulic disk brake, comprise: levorotation brake calipers, right type brake calipers and brake holder, levorotation brake calipers is identical with the structure of right type brake calipers, comprise oil-hydraulic cylinder, piston, disc spring group, upper cover, setscrew nut, indicator, spring bolt, spring, connecting rod, connecting bolt, brake shoe and friction plate, upper cover is fixedly connected with by connecting bolt with oil-hydraulic cylinder, piston is placed in oil-hydraulic cylinder, oil-hydraulic cylinder is provided with pressure oilhole, pressure oilhole is communicated with the oil pocket in oil-hydraulic cylinder, the oil-hydraulic cylinder of levorotation brake calipers and the oil-hydraulic cylinder of right type brake calipers are fixedly mounted in brake holder by high-strength bolt symmetry, it is characterized in that: described levorotation brake calipers and right type brake calipers oil-hydraulic cylinder bottom center position have and the hole communicated in oil-hydraulic cylinder, described piston is the spindle-type piston of middle part with shoulder, described disc spring group is sleeved on the shaft part on piston land top, upper-end surface and the upper cover inner top surface of disc spring group connect, connect above the lower end surface of disc spring group and piston land, the shaft part of piston land bottom is arranged in the hole of oil-hydraulic cylinder bottom surface, seal with hole and be slidably connected, the end face of piston land bottom shaft part is concordant with oil-hydraulic cylinder outer bottom, space below piston land and between oil-hydraulic cylinder inner bottom surface is oil pocket, piston land side and oil-hydraulic cylinder inner side surface are provided with seal arrangement, the position at four angles of described oil-hydraulic cylinder has the hole of through oil-hydraulic cylinder top and bottom, four connecting rods are placed in hole, connecting rod and hole are slidably matched, connecting rod upper and lower end face has screw, spring bolt is connected on the screw of small end face, described spring housing is contained on spring bolt bar, described brake shoe is fixedly connected on the screw of the lower end surface of connecting rod by connecting bolt, connect with oil-hydraulic cylinder outer bottom above brake shoe, described friction plate is fixed on below brake shoe,
Industrial hydraulic disk brake of the present invention, it is characterized in that: described upper cover central position has and the screw communicated in oil-hydraulic cylinder, described setscrew nut is threaded connection and covers upper, the central position of described setscrew nut has through tapped hole, described indicator is arranged in the tapped hole of setscrew nut by screw thread, and the end face of indicator lower end and piston land top shaft part connects.
Working principle of the present invention is: industrial hydraulic disk brake of the present invention is passive brake, i.e. hydraulic system release, and levorotation brake calipers and right type brake calipers are in clamping station under the effect of respective disc spring group.When hydraulic system release, disc spring group discharges, promotion piston moves downward, piston stretches out oil-hydraulic cylinder, promotes brake shoe and moves downward, be positioned at friction plate on brake shoe gradually near brake disc, realize brake, when brake shoe moves downward, drivening rod moves downward, and connecting rod drives spring bolt to move downward with connecting rod, makes to be sleeved on the spring-compressed on spring bolt bar.When hydraulic system is pressurizeed, when hydraulic system oil pressure is greater than the pre-compression force of disc spring group, piston moves upward under the effect of hydraulic oil, make in piston retraction oil-hydraulic cylinder, brake shoe moves upward under the action of the spring, and make the friction plate on brake shoe depart from brake disc, break declutches.
Setscrew nut, for changing the relative position of piston, realizes the adjustment of brake clearance.Due between setscrew nut with upper cover for being threaded, the position of setscrew nut lower end can be adjusted by rotating setscrew nut, thus change the position that piston upper end arrives, realize brake clearance adjustment.The wear extent of friction plate can be observed intuitively by the adjustment amount of setscrew nut.
Indicator is connected with setscrew nut by screw thread, and its lower end contacts with piston upper-end surface, and in brake operation process, the inner contact moving through indicator of piston carrys out sender, realizes the monitoring to brake operation state.
The invention has the beneficial effects as follows:
1. brake structural compact volume is little, lightweight;
2. piston directly acts on friction plate, can not produce the catching phenomenon of mechanical structure;
3. the Installation and Debugging of brake cabin friction plate are convenient, and gap is easy to adjustment, and the safety reliability of break is high, are convenient to onsite application and safeguard;
4. about, brake calipers uses brake holder to connect, and coordinates brake disc size adjustable, and applicability is strong, is applicable to various installation site.
