Abstract

The utility model discloses a lifter for multiple rails in the field of lifters. A clamping mechanism, which comprises a clamping plate box, is hung on the lower ends of a left hooking plate and a right hooking plate; two outer clamping plates are arranged in the clamping plate box; a middle clamping plate is clamped between the two outer clamping plates; lifting lugs which are hinged with the lower end of the right hooking plate is arranged on the upper ends of the outer clamping plates; a lifting lug which is hinged with the lower end of the left hooking plate is arranged on the upper end of the middle clamping plate; a plurality of forward hooking heads, the working surfaces of which face one side, are intervallically arranged on the lower ends of the outer clamping plates; reverse hooking heads, which have an one-to-one correspondence with the forward hooking heads but the working surfaces of which are opposite to the working surfaces of the forward hooking heads, are arranged on the lower end of the middle clamping plate; a jaw which can clamp rails is formed between the forward hooking heads and the corresponding reverse hooking heads; at least two waist-shaped penetrating sockets are arranged along a horizontal direction on the outer clamping plates and the middle clamping plate; penetrating pin shafts are arranged in the penetrating sockets; and both ends of each penetrating pin shaft are fixed on the clamping plate box. The lifter can simultaneously lift multiple rails, thus increasing working efficiency. The lifter can be used in lifting places where rails are orderly arranged, such as a rail production line.

Description

Many one steel rails suspender

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 suspender that is used for the single rail of handling is arranged, it mainly comprises the plate by the Left-wing Federation, 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, 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 the upper pin overhead hoist, 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: during this device handling rail, can only single handling, and the many one steel rails of handling simultaneously, its work efficiency is lower.

The utility model content

The purpose of this utility model provides a kind of many one steel rails suspender, makes the many one steel rails of its handling simultaneously.

The purpose of this utility model is achieved in that many one steel rails suspender, comprise Left-wing Federation's plate, right yoke plate, left side hook plate and right hook plate, 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, be provided with switch circuit controller between upper pin and the lower bearing pin, described left hook plate and the suspention of right hook plate lower end have a clamping device, described clamping device comprises the clamping plate case, be provided with two external splints in the clamping plate case, clamping has middle splint between two external splints, the external splint upper end is provided with the hanger that is hinged with the right hook plate lower end, the middle splint upper end is provided with the hanger that is hinged with left hook plate lower end, the external splint lower end is interval with the forward gib head of some driving surfaces towards a side, and the middle splint lower end is provided with reverse gib head corresponding one by one with the forward gib head but that driving surface is opposite, but forms the jaw of clamping rail between forward gib head and the cooresponding reverse gib head; Along continuous straight runs is provided with at least that twice waist shape is run through groove on external splint and the middle splint, described run through to be provided with in the groove run through bearing pin, run through the bearing pin two ends and be fixed on the clamping plate case.

During the utility model work, with shackle and suspension ring from upper pin this device of slinging, during initial condition, the snap close and the tapered end of switch circuit controller are interlocked, jaw is locked in open configuration, each jaw all can hold an one steel rail and insert, when suspension ring to transferring, when making clamping device touch the rail upper surface, switch circuit controller moves once, and the snap close and the tapered end of switch circuit controller are separated, at this moment, can upwards lift by crane the utility model, external splint and middle splint produce relative motion, and kidney slot can guarantee that with the annexation that runs through bearing pin external splint and middle splint have relative motion leeway, forward gib head and reverse gib head synergy, jaw is dwindled, and the corresponding work face clamps rail, some rail can be sling simultaneously; Unload when putting rail, middle splint and external splint produce move toward one another once more, and jaw is opened, and simultaneously, the switch circuit controller action is in the lock state jaw, for lifting next time is got ready.Compared with prior art, the many one steel rails of the utility model handling have simultaneously improved work efficiency, can be used for the rail handling place of proper alignment, on the Rail Production line.
