Description
Technical field
The present invention relates to a kind of safe braking vehicle of monorail crane for mines drg.
Background technology
When exploiting colliery or iron ore, engineering staff or exploitation workman generally take to mine under man car, or take tunnel man-bus at gallery and commute Work places.When not going wrong, personnel in the pit can safety work, but safety misadventure can be caused to mine-used man-vehicle and the personnel taking mine-used man-vehicle when the malfunctioning and manual engaging means of automatic engaging means that mine-used man-vehicle's circulation line occurs obstacle or occurs the fracture of winch out of control or traction wire rope and people's car is ineffective again, therefore have relevant standard in Coal Industry of China standard MT/T883-2000: a braking car after being defined in last people's car, should be hung.
Existing safe braking vehicle of monorail crane for mines has the brake equipment of two types usually, and first is relative plug-in type braking type device, namely two of this stop mechanism inserts the pawls pawl that can fall in time when breaking down and reaches the object of braking; Second is relatively embrace rail braking type device, and namely when breaking down, this stop mechanism can embrace two orbital planes in time to reach the object of braking.The stroke of these two kinds of stop mechanism brakings is long, thus causes braking time longer, and structure comparison is single, and braking effect is bad.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of safe braking vehicle of monorail crane for mines drg, in time, Stability Analysis of Structures, improves indicating brake action, guarantees braking effect further in braking.
To achieve these goals, the technical solution used in the present invention is: a kind of safe braking vehicle of monorail crane for mines drg, comprises frame, brake shoe brake cheek, bearing pin, hinge ear, disc spring guide pin bushing, disc spring, piston rod, piston, spacer, piston bush and door.Wherein, frame is foundry goods, and top has through hole, and through hole right-hand member has screw thread; Spacer left end is arranged on the right side in frame through hole, left end has screw thread, the screw thread fit opened with frame through hole right-hand member, spacer right-hand member periphery is provided with draw-in groove, and piston is arranged in draw-in groove, piston casing pressure is pressed on the right side of spacer by fastener,, door is pressed on the right side of piston bush, is connected with piston bush by fastener, have through hole in the middle of door, through hole arranges screw thread; Piston rod is stepped, be arranged on the left side in frame through hole, disc spring is inserted in piston rod, and disc spring guide pin bushing is enclosed within disc spring outer ring, through hole is had in the middle of disc spring guide pin bushing, have screw thread in through hole, hinge ear is arranged in the through hole of disc spring guide pin bushing, and right-hand member has screw thread, with the screw thread fit opened in disc spring guide pin bushing through hole, brake shoe brake cheek rolls block and braking by braking and rolls block and combine and form, and is arranged on the left of hinge ear, passes through pinned connection with hinge ear.
Further, also comprise dust excluder, dust excluder is arranged on the through hole of door, and left end has screw thread, the screw thread fit opened with door through hole.
The present invention arranges disc spring in frame, adopts disc spring braking, improves braking force; Meanwhile, arrange piston rod in frame, piston rod is designed to stepped, increases oil pressure area, reduces oil pressure, thus reduce the difficulty of braking, ensure that the effect of braking; Further, adopt single shaft fixedly to roll block in device, allowing to roll block has certain swing allowance, ensures that brake surface and track web are fitted, reduces impact, decrease the stroke of braking simultaneously, guarantee that whole device can be braked in time.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of safe braking vehicle of monorail crane for mines drg, comprises frame 1, brake shoe brake cheek 2, bearing pin 3, hinge ear 4, disc spring guide pin bushing 5, disc spring 6, piston rod 7, piston 8, spacer 9, piston bush 10 and door 11; Frame 1 is foundry goods, and top has through hole, and through hole right-hand member has screw thread; Spacer 9 left end is arranged on the right side in frame 1 through hole, spacer 9 left end has screw thread, the screw thread fit opened with frame 1 through hole right-hand member, spacer 9 right-hand member periphery is provided with draw-in groove, and piston 8 is arranged in draw-in groove, and piston bush 10 is pressed and is pressed on the right side of spacer 9 by fastener, door 11 is pressed on the right side of piston bush 10, be connected with piston bush 10 by fastener, have through hole in the middle of door 11, through hole arranges screw thread; Piston rod 7 is stepped, be arranged on the left side in frame 1 through hole, disc spring 6 is inserted in piston rod, and disc spring guide pin bushing 5 is enclosed within disc spring 6 outer ring, through hole is had in the middle of disc spring guide pin bushing 5, have screw thread in through hole, hinge ear 4 is arranged in the through hole of disc spring guide pin bushing 5, and right-hand member has screw thread, with the screw thread fit opened in disc spring guide pin bushing 5 through hole, brake shoe brake cheek 2 rolls block and braking by braking and rolls block and combine and form, and is arranged on the left of hinge ear 4, is connected with hinge ear 4 by bearing pin 3.
