Aforesaid self-locking type suspender, is characterized in that, also comprises: equalizer bar, aforementioned equalizer bar is arranged on the adapter shaft of suspender frame under.
Aforesaid self-locking type suspender is characterized in that aforementioned equalizer bar has the bottom surface of level.
Aforesaid self-locking type suspender is characterized in that the bottom surface of aforementioned equalizer bar is frame-shaped construction.
Aforesaid self-locking type suspender, is characterized in that, on aforementioned suspender frame, is provided with pulley.
Aforesaid self-locking type suspender, is characterized in that, the connection mode between aforementioned locating dowel pin and dead bolt case is welding.
Usefulness of the present utility model is: simple in structure, easily manufacture; The equalizer bar of configuration can make location more accurate; Adopt zig-zag cylindrical cam structure, can realize the dead bolt rotary self-locking, substituted existing electrodynamic type locking device, do not expend the energy, more environmental protection.
The accompanying drawing explanation
Fig. 1 is the structural representation of a specific embodiment of the utility model self-locking type suspender;
Fig. 2 is the structural representation of the sawtooth cam cylinder dead bolt of self-locking type suspender in Fig. 1.
The implication of Reference numeral in figure: 1-suspender frame, 2-dead bolt case, 3-sawtooth cam cylinder dead bolt, 4-locating dowel pin, 5-lock tongue slot, 6-diamond block, 7-equalizer bar, 8-pulley, 9-groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
See figures.1.and.2, self-locking type suspender of the present utility model comprises: suspender frame 1 and the self-locking mechanism that is arranged on suspender frame 1 side.This self-locking mechanism comprises: the dead bolt case 2 be fixedly connected with suspender frame 1, and the lock tongue slot 5 that is arranged on dead bolt case 2 belows be fixedly connected with suspender frame 1, and be arranged on sawtooth cam cylinder dead bolt 3 and the locating dowel pin 4 in dead bolt case 2.Wherein, an end of locating dowel pin 4 is fixed on the sidewall of dead bolt case 2, and the other end stretches in the groove 9 of sawtooth cam cylinder dead bolt 3; Sawtooth cam cylinder dead bolt 3 vertically arranges, and head is diamond block 6 and stretches out dead bolt case 2, and the major axis of diamond block 6 and minor axis length do not wait.
As a kind of preferred scheme, the connection mode between locating dowel pin 4 and dead bolt case 2, for welding, is connected firmly, and can guarantee the safety of using.
The principle of work of the self-locking mechanism of self-locking type suspender of the present utility model is as follows: what diamond block 6 was vertical stretches in lock tongue slot 5, until diamond block 6 props up the bottom of lock tongue slot 5, in the process that continues to descend at suspender frame 1, sawtooth cam cylinder dead bolt 3 carries out rotation under the common directional tagging of locating dowel pin 4 and groove 9, after 90-degree rotation, diamond block 6 just is stuck in lock tongue slot 5, completes lock out action; If carry out a suspender, naturally move down, sawtooth cam cylinder dead bolt 3 is 90-degree rotation again again, thereby separating lock glossal canal 5 completes the release action.Because self-locking mechanism has replaced original electrodynamic type locking device, do not expend the energy, more environmental protection.
As a kind of preferred scheme, self-locking type suspender of the present utility model also comprises: equalizer bar 7, equalizer bar 7 is arranged on the adapter shaft of suspender frame 1 under.The equalizer bar 7 of configuration can make location more accurate, more convenient to operate.
More preferably, equalizer bar 7 has the bottom surface of level, is convenient to be pressed in open form charging basket central circular mouth place straightly.
Most preferably, the bottom surface of equalizer bar 7 is frame-shaped construction, can effectively be pressed in open form charging basket central circular mouth place, can alleviate again the weight of suspender integral body.
In order to reduce the wearing and tearing of travelling crane hook to suspender frame 1, be provided with pulley 8 on suspender frame 1.
The working process of self-locking type suspender of the present utility model is:
Travelling crane hook tangles this suspender, move it open form charging basket central circular mouth place, vertical drop, now suspender frame 1 is rounding state, suspender frame 1 lower end slowly enters the charging basket circular port, to being balanced frame 7 after certain depth, block, now suspender frame 1 lower end starts outer support, and sawtooth cam cylinder dead bolt 3 falls to entering in lock tongue slot 5 simultaneously, under the directional tagging of locating dowel pin 4, sawtooth cam cylinder dead bolt 3, from turning 90 degrees, reaches locking-in state, now moving charging basket capable of hoisting; After moving to destination, then carry out a suspender and naturally move down, make sawtooth cam cylinder dead bolt 3 90-degree rotation again, thus separating lock glossal canal 5, and the uphill process suspender becomes rounding state, just removable suspender.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
