Description
[technical field]
The invention belongs to elevator machinery technical field, particularly relate to a kind of packaged type hoisting chain inhibiting device for the small-sized bottle gouard moved by hands such as chain block, Lever Blocks.
[background technology]
Bottle gouard moved by hands is (as chain block, Lever Blocks) inhibiting device of tail chain ring must be provided with in standard-required, its objective is to prevent complete machine at work, the safety misadventure that the hoisting chain of load end declines fast or brake equipment inefficacy etc. causes, this inhibiting device is generally fixed in actual applications, or tail chain ring is fixed on cucurbit body, only have to this inhibiting device competence exertion effect during smallest limit, because inhibiting device is only spacing for tail chain ring, therefore the inhibiting device height and position that cannot constantly change according to hoisting heavy according to actual needs and be installed on the relevant position of hoisting chain active section movably, namely inhibiting device is cannot its spacing required installation site of free adjustment, thus can not play to rapid reaction the practical function preventing complete machine operational failure.
[summary of the invention]
The invention provides a kind of packaged type hoisting chain inhibiting device, it can be installed on the relevant position of hoisting chain active section by adjustable ground according to actual needs flexibly movably, thus prevents complete machine to lose efficacy in advance.
It is as follows that the present invention solves the problems of the technologies described above adopted technical scheme:
Packaged type hoisting chain inhibiting device, for hoisting chain when coordinating bottle gouard moved by hands braking failure suddenly declines and implements spacing, described packaged type hoisting chain inhibiting device is by packaged type spacing ring, tail chain ring fastener forms, packaged type spacing ring is provided with for the current chain annular groove of hoisting chain, the locking groove that restriction hoisting chain passes through and the open slot installed for the tail chain ring of hoisting chain, wherein, chain annular groove and locking groove intercommunication and surround, open slot is positioned at the bottom of packaged type spacing ring, the open end both sides of open slot are equipped with through hole, tail chain ring fastener is arranged through through hole, portable spacing ring has spigot surface and stopping step in locking groove periphery, this spigot surface and stopping step are bonded Ω shape, and spigot surface tilts.
Above-mentioned tail chain ring fastener is made up of screw bolt and nut, and wherein, nut is retaining nut, like this, after tail chain ring is fixed on open slot, is unlikely and causes tail chain ring to be deviate from open slot because of nut loosening.
The advantage that the present invention has and beneficial effect as follows:
Simple installation of the present invention, by hoisting chain through chain annular groove, makes hoisting chain be free to travel to suitable position in chain annular groove, then hoisting chain is slided to locking groove position, to reserve initial restraining position, then tail chain ring is placed in open slot is fixed.
With initial restraining position for starting point, in lifting overall process, need the continuous change according to weight height and position and frequently adjust the present invention and be positioned at restraining position (namely regulating the real work length of hoisting chain) on hoisting chain, be beneficial to the present invention near cucurbit body, during each adjustment, only must by hoisting chain slippage in chain annular groove, packaged type spacing ring can be free to travel to required position along hoisting chain, then hoisting chain is slided to locking groove position can realize, the effect regulating hoisting chain real work length can be played by chain annular groove.
When needing braking in hoisting heavy way, only need hoisting chain slippage in chain annular groove, so can move up the present invention, slip between two blocks of wallboards of cucurbit matrix to make the spigot surface of packaged type spacing ring, and stopping step and two blocks of wallboards are conflict state, due to chain annular groove and locking groove intercommunication, need not any instrument during hoisting chain slippage, need not dismantle and reconnect any articles (such as latches such as detachable, pinch circle, elastic cylindrical pin etc.), easy and simple to handle, work efficiency is high, the chain annular groove of packaged type spacing ring and locking groove have the effect of two stations.
Weight is caused to drive hoisting chain suddenly to drop rapidly once bottle gouard moved by hands braking failure; packaged type spacing ring is followed rapidly and is moved; its spigot surface enters in cucurbit matrix smoothly; stopping step immediately fast dieback in the bottom of two blocks of wallboards; both protected complete machine, the serious consequence that braking sudden failure brings can be prevented again.
[accompanying drawing explanation]
Be described in further detail with regard to the present invention below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
[detailed description of the invention]
Please refer to shown in Fig. 1, is preferred embodiment of the present invention.
Packaged type hoisting chain inhibiting device, for coordinating hoisting chain 1 descending spacing and implementing suddenly during bottle gouard moved by hands braking failure, packaged type hoisting chain inhibiting device is made up of packaged type spacing ring, tail chain ring fastener, packaged type spacing ring is provided with and supplies the current chain annular groove 4 of hoisting chain 1, limits the locking groove 5 that hoisting chain 1 passes through and the open slot 8 installed for the tail chain ring 10 of hoisting chain 1.
Wherein, chain annular groove 4 and locking groove 5 intercommunication, open slot 8 is positioned at the bottom of packaged type spacing ring, and the open end both sides of open slot 8 are equipped with through hole 9, tail chain ring fastener is arranged through through hole 9, and the packaged type spacing ring of locking groove 5 periphery has spigot surface 2 and stopping step 3.
After packaged type spacing ring has spigot surface 2, make between its two blocks of wallboards more easily slipping into cucurbit matrix, for this reason, when specifically implementing, its width of spigot surface 2 being positioned at packaged type spacing ring head is less than two pieces of wallboard spacing of supporting cucurbit; The width of stopping step 3 is more than or equal to two pieces of wallboard spacing.
Tail chain ring fastener is made up of bolt 7 and nut 6, and wherein, nut 6 is retaining nut.
During concrete installation, first tail chain ring 10 is filled in chain annular groove 4, make hoisting chain 1 by chain annular groove 4, hoisting chain 1, to suitable position, then slides in locking groove 5 by mobile the present invention, and then put hoisting chain 1 tail chain ring 10 into open slot 8 place, after passing the hole of two through hole 9, tail chain ring 10 with bolt 7 again, with nut 6 by fastening for bolt 7, namely this device has assembled, since then, for bottle gouard moved by hands adds one brand-new catch siding.
