Description
Technical field
The utility model relates to a kind of suspender, particularly is used for the suspender of handling rail.
Background technology
In the prior art, a kind of single rail suspender is arranged, mainly by Left-wing Federation's plate, right yoke plate, left side hook plate and right hook plate are formed, Left-wing Federation's plate and right yoke plate upper end are hinged through upper pin, Left-wing Federation plate lower end and left hook plate upper end are hinged, right yoke plate lower end and right hook plate upper end are hinged, left side hook plate and right hook plate middle part are hinged through lower bearing pin, left side hook plate and right hook plate lower end are provided with the gib head that is used for the clamping rail, be provided with the switch circuit controller (patent No.: ZL200520070269.3) between upper pin and the lower bearing pin, this switch circuit controller is made up of the snap close and the tapered end of intermittently folding, and axial action once can and be thrown off between two states and change once in locking between snap close and the tapered end.During work, by this device of upper pin handling, when lower bearing pin moved downward relatively, the spacing between the gib head was dwindled, and rail can be sling, otherwise then the spacing between the gib head became big, rail can be unclamped; The switch circuit controller intermitten makes gib head can be locked in open configuration, so that next handling.Its weak point is: in the time of in the process of this device handling rail, gib head itself can not self-locking, as factors such as external force collisions, may cause that rail comes off in the handling process, causes the accident.
The utility model content
The purpose of this utility model provides a kind of mechanical boxlike list rail suspender, makes the gib head can self-locking, to improve the safety of handling process.
The purpose of this utility model is achieved in that mechanical boxlike list rail suspender, but two gib heads that comprise the clamping rail, described gib head is arranged in the box body, the box body front, the back side and both sides are all sealed, box body top is provided with an opening, be inserted with hanger in the opening, the inboard of the front and back of box body is provided with longitudinal fluting, hanger is provided with the boss that inserts in the longitudinal fluting, the hanger lower end is connected with the switch circuit controller upper end, switch circuit controller lower end channels and activating collaterals joint is connected with voussoir, middle side part is provided with a breach under the described box body, and two gib heads are sold axle mounting respectively between the front and back of box body, and two gib heads are symmetrical arranged, expose from breach two gib head lower ends, the outer upside of two gib heads is respectively equipped with and orders about the open torsion spring of two gib heads, and the interior upside between two gib heads is provided with pushes step, and the forward surface of two gib heads is the plane and is positioned at the voussoir below, when gib head was in clamped condition, voussoir can insert between two forward surfaces just.
During the utility model work, can be through steel rope, pulleys etc. are sling this suspender from the hanger upper end, hanger longitudinally groove slides up and down and does not deviate from, when to transferring this suspender when making rail enter in the breach, the gib head lower end push step contact rail, rail upwards forces gib head to overcome the torsion spring application force and rotates, make gib head clamp rail, hanger continues descending, then the switch circuit controller breakdown action, voussoir is inserted between two forward surfaces, at this moment, can lift by crane rail, wedge shape can not deviate from between the forward surface because of lifting soon, and gib head can not open, also can keep clamped condition even run into the external force collision, arrive and unload when putting the position, unload downwards and put this suspender, after rail contacts to earth, the switch circuit controller closed action is lifted by crane this suspender once more, and voussoir can break away from two forward surfaces with the pull-up of switch circuit controller, the moment that switch circuit controller breaks away from, torsion spring promotes gib head and opens, and rail breaks away from gib head, realizes unloading putting, keep open configuration between the gib head, for lifting next time is got ready.From above-mentioned working process as can be seen, the utility model is in the failure-free self-locking state between the gib head when the handling rail, and rail can be because of outer force-disturbance come off, and its use is more safe and reliable; This device is exclusively used in the lifting job of single rail, also can a plurality of use arranged side by side, and with the many one steel rails of while handling.
For improving reliability of service, described switch circuit controller comprises sleeve, cooperate in the sleeve and be provided with S. A., the sleeve upper end is connected with hanger, the S. A. lower end is provided with flexible joint, S. A. is provided with a circumferential recess, after circumferential recess is launched, the upper and lower wall toothing ripple of circumferential recess is provided with, the crest of described zigzag wave, trough are even number one to one, the crest of zigzag wave is corresponding to the descent stage of zigzag wave on the lower wall surface on the upper wall surface, and the trough of zigzag wave is corresponding to the ascent stage of zigzag wave on the upper wall surface on the lower wall surface; Crest place, every interval is provided with one along the upwardly extending vertical straight trough in S. A. surface on the upper wall surface, and cartridges sides is provided with the guiding bearing pin of at least one diameter less than vertical straight trough width, and the guiding bearing pin radially inserts in the circumferential recess along sleeve.Sleeve and S. A. axially reciprocating are once, upper wall surface and lower wall surface promote S. A. and turn an angle, the guiding bearing pin is then from the crest location of upper wall surface with vertically change between the straight trough, and correspondingly, S. A. from the exsertile axial length of sleeve intermittent the variation is taken place.Technical scheme is simple in structure, and is easily manufactured, uses reliable.
For voussoir can more stably be inserted between two spigot surfaces, described box body front and back is respectively equipped with and the corresponding chute of voussoir, and side is provided with locating dowel pin before and after the voussoir, and locating dowel pin inserts in the described chute.Voussoir can slide along the chute direction, can avoid voussoir to rotate, and makes its use more reliable.
