Description
The utility model relates to the anti-fall catching device of a kind of rail skip bucket, and it is anti-fall to be particularly useful for vertical shaft hoisting skip bucket (container), and it is anti-fall to be applicable to that also building promotes.
The elevator system safety guard-safeguard is the important step that mine is produced; mine vertical shaft adopts the mode that promotes skip bucket (container) to finish transport; the important tool that to promote matching used rail skip bucket then be the main shaft hooist coal; but because the not protection of disconnected slack rope; therefore skip bucket bob well incident happens occasionally, and production brings very big loss to mine.For a long time, the problem of disconnected rope creep protection is a problem anxious to be solved always, if the cage anti-fall device is borrowed, the skip bucket deadweight is increased, and the amount of shaft equipment change simultaneously also strengthens, and the installation site is limited, and its investment also increases, thereby inapplicable.
The purpose of this utility model provide a kind of can emergency braking, in light weight, dependable performance plays the anti-fall catching device of rail skip bucket of disconnected rope creep protection effect.
The anti-fall catching device of a kind of rail skip bucket of the utility model, it comprises the skip bucket pull bar, channel-section steel support and symmetrical channels base steel frame are provided with wedge system in the groove of described channel-section steel pedestal, be provided with the symmetrical connecting rod mechanism that links with pull bar in the support inboard, the pull bar lower end is provided with displacement aperture, the displacement of displacement aperture is apart from being H, and main shift fork one end and the rocking arm of connecting rod mechanism are hinged, and the other end and secondary shift fork are articulated on the pedestal, and extending the fork-shaped spring pedestal that is fixedly connected, spring is fixed on the guide rod between base and support; Secondary shift fork symmetry is walked around spring and is extended in the wedge system.
The anti-fall catching device of a kind of rail skip bucket of the utility model, the wedge system that is located in the channel-section steel base recess is made up of voussoir seat, voussoir, defelctor apron, the voussoir seat by screw, be bolted in the groove of channel-section steel pedestal, the identical voussoir seat symmetry of voussoir is located at the both sides of steel guide rail, defelctor apron by screw retention on the voussoir seat, the relative steel guide rail of voussoir side is provided with many group sawtooth, and the voussoir afterbody has the porthole of secondary shift fork.The displacement of pull bar is 50～60 centimetres apart from H.
The anti-fall catching device of a kind of rail skip bucket of the utility model, it is anti-fall to be best suited for vertical shaft hoisting skip bucket (container), also is applicable to other equipment anti-fall of vertical-lifting.Connecting rod mechanism and voussoir linkage are set on former channel-section steel support and pedestal, voussoir is provided with sawtooth, utilize the sawtooth force of cut as anti-fall braking force, the tenesmus container is arrested braking, and its braking force is reliable, and mechanism is flexible, complete machine is in light weight, need not increase auxiliary facilities, can thoroughly stop the skip bucket falling accident that disconnected slack rope causes, have practicality widely.
Description of drawings:
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure birds-eye view.
Fig. 3 is the utility model structure side view.
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
The anti-fall catching device of a kind of rail skip bucket of the utility model, it mainly is made up of connecting rod mechanism and voussoir linkage.The symmetrical connecting rod mechanism that links with skip bucket pull bar 6 is set in channel-section steel support 9, and the bottom of pull bar 6 is provided with a hole, and bearing pin 7 passes the middle part that displacement aperture is fixed on support 9, and the displacement H of displacement aperture is 55 centimetres.Main shift fork 5 one ends and the rocking arm 13 of two symmetrical connecting rod mechanisms are hinged, the other end and secondary shift fork 4 are articulated on the pedestal 8, and extend the fork-shaped spring pedestal 12 that is fixedly connected, and spring pedestal 12 is provided with spring 3, spring 3 is fixed on the guide rod between base and support, and spring 3 is with main shift fork 5 actions; Secondary shift fork 4 symmetries are walked around spring 3 and are extended in the wedge system, and wedge system is moved with connecting rod mechanism.Wedge system is located in the groove of channel-section steel pedestal 10, wedge system is by voussoir seat 1, voussoir 2, defelctor apron 12 is formed, voussoir seat 1 by screw, be bolted in the groove of channel-section steel pedestal 10, voussoir 2 voussoir seat 1 symmetries of coincideing are located at the both sides of steel guide rail 11, defelctor apron 14 by screw retention on voussoir seat 1, voussoir 2 relative steel guide rails 11 sides are provided with some little sawtooth, and voussoir 2 afterbodys have the porthole of secondary shift fork 4.When skip bucket normally moves, pull bar 6 pull-up connecting rod mechanisms, its main shift fork back-moving spring, and it is descending to drive secondary shift fork, and it is descending that secondary shift fork 4 of while is stirred voussoir 2, and voussoir 2 leaves rail 11 under the ramp effect of voussoir seat 1; When container does not have the lifting pulling force, during promptly disconnected the rope, pull bar is walked displacement apart from H 6 times, main shift fork 5 interlock springs 3 are up, it is up that simultaneously secondary shift fork 4 drives tapered wedges 2, and voussoir 2 presses to rail 11 under the effect of voussoir seat 1, the many groups sawtooth cutting incision rail in the jam-packed rail on the voussoir 2, the antagonistic force of jam-packed power and cutting makes the container braking, and the size of braking is by the control of cutting sawtooth size.After the container hoisting rope recovers pulling force, pull bar 6 pull-ups, main shift fork 5 is tightened up, secondary shift fork 4 interlocks, when carrying on container, voussoir seat 1 separates with voussoir 2, and jam-packed cutting voussoir 2 on rail road 11 unclamps and falls automatically by its deadweight, and beginning is operation normally.
