Description
Technical field
The application belongs to industrial safety break technical field, relates in particular to industrial hydraulic brake.
Background technique
On the large lifting equipment of at present industrial enterprise's application such as Iron And Steel Plant, shipyard, widely used safety type hydraulic caliper-disc brake is the realization that the power transmission that relies on mechanical structure guarantees brake functionality.The safety type hydraulic caliper-disc brake structure of prior art is: friction disc device links together by connecting rod, attachment screw and pressure-bearing cover plate.And pressure-bearing cover plate links together by screw and setscrew nut.Wherein setscrew nut and piston rod are threaded connection.The braking of break and the action of declutching are that the action of piston driving friction disc device, is the action that indirectly drives friction disc device under hydraulic oil and the assembly of dish spring are closed.The start and stop action of break detects sender by indicator switch, and indicator switch links together by welding support and piston rod, indirectly realizes motion detection functionality.The deficiencies in the prior art are; Break, due to the more complicated that realizes of mechanical structure braking force, easily causes clamping stagnation, thereby affects the normal use of break, even causes serious security incident., compare with the break of directly realizing braking force structural type, weight is relatively large meanwhile, on-the-spot installation, inconvenient debugging, and friction plate is changed difficulty.
Summary of the invention
The object of this invention is to provide a kind of industrial hydraulic brake, overcome the deficiencies such as the easy clamping stagnation of poor structure rigidity, force transfer mechanism, the inconvenience of friction lining install and adjust, braking reliability that existing break exists are low.
Technological scheme of the present invention is: industrial hydraulic 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, dish 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 the oil-hydraulic cylinder of levorotation brake calipers and right type brake calipers is 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 communicating in oil-hydraulic cylinder, described piston is that middle part is with the axle type piston of shoulder, described dish spring group is sleeved on the shaft part on piston land top, upper-end surface and the upper cover inner top surface of dish spring group connect, the lower end surface of dish spring group and connecting above piston land, the shaft part of piston land bottom is arranged in the hole of oil-hydraulic cylinder bottom surface, be dynamically connected with hole sealed sliding, 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 that connects 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 small end face screw, described spring housing is contained on spring bolt bar, described brake shoe is fixedly connected on by connecting bolt on the screw of lower end surface of connecting rod, above brake shoe, connect with oil-hydraulic cylinder outer bottom, described friction plate is fixed on below brake shoe,
Industrial hydraulic brake of the present invention, it is characterized in that: described upper cover central position has and the screw communicating in oil-hydraulic cylinder, described setscrew nut is threaded connection upper and covers, the central position of described setscrew nut has the tapped hole of perforation, described indicator is arranged on by screw thread in the tapped hole of setscrew nut, and the end face of indicator lower end and piston land top shaft part connects.
Working principle of the present invention is: industrial hydraulic brake of the present invention is passive brake, i.e. hydraulic system release, levorotation brake calipers and right type brake calipers under the effect of dish spring group separately in clamping station.When hydraulic system release, dish spring group discharges, promotion piston moves downward, oil-hydraulic cylinder is stretched out in piston lower end, promotes brake shoe and moves downward, and is 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 dish spring group, piston moves upward under the effect of hydraulic oil, make in piston lower end retraction oil-hydraulic cylinder, brake shoe moves upward under the effect of spring, makes the friction plate on brake shoe depart from brake disc, and break declutches.
Setscrew nut, for changing the relative position of piston, is realized the adjustment of brake clearance.Due between setscrew nut and upper cover for being threaded, by rotation setscrew nut, can adjust the position of setscrew nut lower end, thereby change the position that piston upper end arrives, realize brake clearance adjustment.By the adjustment amount of setscrew nut, can observe intuitively the wear extent of friction plate.
Indicator is connected with setscrew nut by screw thread, and its lower end contacts with piston upper-end surface, and in break working procedure, the inner contact that moves through indicator of piston is carried out sender, realizes the monitoring to break working 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 adjust, and the safety reliability of break is high, is convenient to on-the-spot working service;
4. left and right brake calipers is used brake holder to connect, and coordinates brake disc size adjustable, and applicability is strong, is applicable to various installation sites.
