Abstract
The invention relates to a gantry hook lifting device span adjusting structure which is used for the lifting beam of a gantry hook lifting device. The gantry hook lifting device span adjusting structure comprises a turning-over plate. The turning-over plate is arranged on a supporting torsion shaft; the upper part of the turning-over plate is provided with two grooves which have the same size and match with the roller shafts of a lifting fork; the two grooves are located on two sides of the supporting torsion shaft respectively; two sides of the lower lifting beam of the turning-over plate are both provided with a limiting block; the grooves are in semicircle shapes; and the two grooves are arranged symmetrically. Due to the adoption of the gantry hook lifting device span adjusting structure, the semi-automatic adjustment is realized, the artificial auxiliary work is omitted, and the labor intensity is reduced. In addition, the accurate position adjustment is realized, and the work efficiency is improved.
Description
Technical field
The present invention relates to the adjustable gantry hook suspender of a kind of span, be applicable to the handling of steel ladle or the ladle of different spans.
Background technology
In metallurgy industry, a kind of gantry hook suspender can only be applicable to a kind of handling of steel ladle or ladle of span.When two kinds of span steel ladle of handling or ladle, just need two kinds of gantry hook suspenders.For the handling of large-tonnage molten steel bag or ladle, gantry hook suspender adopts assembly pulley to be connected with hoisting crane more, change comparatively difficulty of suspender, and the replacing time is long.
Existing span is adjustable, and gantry hook suspender is on original gantry hook suspender, to design two kinds of span location holes, two kinds of location holes communicate and form secured adjusted hole, by artificial and hoisting crane co-ordination, just can make to hang fork shaft left and right action in adjustment hole, reach the object that regulates gantry hook span.
The shortcoming of prior art
1, need human assistance work, after hoisting crane drops to a certain degree, by manually moving, hang fork realization adjusting;
2, people regulates difficulty, is difficult for putting in place, need repeatedly operate, and efficiency is low;
3, the UNICOM of adjustment hole, hangs fork shaft left and right limit strength low.
Summary of the invention
In order to address the above problem, the invention provides a kind of novel gantry hook suspender span adjustable structure.
Object of the present invention is carried out specific implementation by the following technical programs:
A kind of gantry hook suspender span adjustable structure, be applied on the hanging beam of gantry hook suspender, comprise that is arranged on the returning face plate supporting on torsion shaft, the top of described returning face plate is provided with the groove that two identical roll shafts with hanging fork of size coordinate, two described grooves are respectively in the both sides of described support torsion shaft, in the both sides of hanging beam described in the bottom of described returning face plate, are respectively equipped with a limiting stopper.
Described groove is semicircle, and two grooves are symmetrical arranged.
As further optimal design of the present invention, also comprise two coilable reinforcement hooks that separate from both sides, described returning face plate top, described in each, strengthen hook and a bearing pin clamping being arranged on described returning face plate, two described bearing pins are respectively in the both sides of described support torsion shaft.
Described in each, strengthen hook and be arranged on a suspension hook torsion shaft being fixed on described hanging beam, two described suspension hook torsion shafts are respectively in the both sides, top of described support torsion shaft.
Described returning face plate adopts symmetrical structure, and two described limiting stoppers are symmetrical arranged with respect to described returning face plate.
The present invention has realized semi-automatic adjusting, has cancelled human assistance work, has reduced labour intensity; And realized accurately the adjusting of position, improved work efficiency.

The specific embodiment
As Figure 1-3, gantry hook suspender span adjustable structure described in the embodiment of the present invention, be applied on the hanging beam 9 of gantry hook suspender, comprise that is arranged on the returning face plate 6 supporting on torsion shaft 7, the top of described returning face plate 6 is provided with the groove that two identical roll shafts 4 with hanging fork 3 of size coordinate, two described grooves are respectively in the both sides of described support torsion shaft 7, in the both sides of the bottom of described returning face plate hanging beam 9, are respectively equipped with a limiting stopper 8.
Described groove is semicircle, and two grooves are symmetrical arranged.
As shown in Fig. 4 .1-4.3, described groove can directly connect for two semicircles, also can after connection, to connection location, carry out chamfering, also can after connection, to connection location, scabble.
Gantry hook suspender span adjustable structure of the present invention, also comprise two coilable reinforcement hooks 2 that separate from returning face plate 6 both sides, top, described in each, strengthen hook 2 and bearing pin 5 clampings that are arranged on returning face plate, two described bearing pins 5 are respectively in the both sides of described support torsion shaft 6.
Described in each, strengthen hook 2 and be arranged on a suspension hook torsion shaft 1 being fixed on hanging beam, two described suspension hook torsion shafts 1 are respectively in the both sides, top of described support torsion shaft 7.
Described returning face plate 6 adopts symmetrical structure, and two described limiting stoppers 8 are symmetrical arranged with respect to described returning face plate 6.
The roll shaft 4 that hangs fork 3 can be arranged in any one groove, after returning face plate 6 structures are installed respectively in the both sides of each hanging beam like this, just can regulate the position of hanging fork 3 on two returning face plates 6.
The present invention has realized semi-automatic adjusting, has cancelled human assistance work, has reduced labour intensity; And realized accurately the adjusting of position, improved work efficiency.
