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 of a kind of span hook, be applicable to the handling of the steel ladle or the ladle of different spans.
Background technology
In metallurgy industry, a kind of gantry hook 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 hooks.For the handling of large-tonnage molten steel bag or ladle, gantry hook adopts assembly pulley to be connected with hoisting crane more, change comparatively difficulty of suspender, and the replacing time is long.
Existing adjustable gantry of span hook is two kinds of span location holes of design on the hook of original gantry; Two kinds of location holes communicate and form the secured adjusted hole; Through artificial and hoisting crane co-ordination, just can make hang fork shaft in adjustment hole about action, reach the purpose of adjusting gantry hook span.
The shortcoming of prior art
1, needs artificial back work, after hoisting crane drops to a certain degree, move through manual work and to hang fork and realize regulating;
2, the people regulates difficulty, is difficult for putting in place, needs repeatable operation, and efficient is low;
3, the UNICOM of adjustment hole, it is low to hang fork shaft left and right sides limit strength.
Summary of the invention
In order to address the above problem, the present invention provides a kind of later-model gantry hook span adjustable structure.
The object of the invention comes concrete the realization through following technical scheme:
A kind of gantry hook span adjustable structure; Be applied on the hanging beam of gantry hook; Comprise that is installed in a returning face plate that supports on the torsion shaft; The top of said returning face plate is provided with the groove that two identical roll shafts with hanging fork of size cooperate, and two said grooves are respectively in the both sides of said support torsion shaft, and the both sides of hanging beam are respectively equipped with a limiting stopper in the bottom of said returning face plate.
Said groove is semicircle, and two grooves are symmetrical set.
As further optimal design of the present invention, also comprise two coilable reinforcement hooks that separate from both sides, returning face plate top, each said reinforcement hook and a bearing pin clamping that is arranged on the returning face plate, two said bearing pins are respectively in the both sides of said support torsion shaft.
Each said reinforcement hook is installed on the suspension hook torsion shaft that is fixed on the hanging beam, and two said suspension hook torsion shafts are respectively in the both sides, top of said support torsion shaft.
Said returning face plate adopts symmetrical structure, and two said limiting stoppers are symmetrical set with respect to said returning face plate.
The present invention has realized semi-automatic adjusting, has cancelled artificial back work, has reduced labour intensity; And realized the adjusting of position accurately, improved work efficiency.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the constructional drawing of the said gantry of embodiment of the invention hook span adjustable structure running condition one.
Fig. 2 is the constructional drawing of the said gantry of embodiment of the invention hook span adjustable structure running condition two.
Fig. 3 is the constructional drawing of the said gantry of embodiment of the invention hook span adjustable structure running condition three.
Fig. 4 is the groove structure figure of returning face plate.
The specific embodiment
Shown in Fig. 1-3; The described gantry of embodiment of the invention hook span adjustable structure; Be applied on the hanging beam 9 of gantry hook, comprise that is installed in a returning face plate 6 that supports on the torsion shaft 7, the top of said returning face plate 6 is provided with the groove that two identical roll shafts 4 with hanging fork 3 of size cooperate; Two said grooves are respectively in the both sides of said support torsion shaft 7, and the both sides of hanging beam 9 are respectively equipped with a limiting stopper 8 in the bottom of said returning face plate.
Said groove is semicircle, and two grooves are symmetrical set.
Shown in Fig. 4 .1-4.3, said groove can be two semicircle direct connections, also can after connection, carry out chamfering to connection location, also can after connection, scabble connection location.
Gantry according to the invention hook span adjustable structure; Also comprise two coilable reinforcement hooks 2 that separate from both sides, returning face plate 6 top; Each said reinforcement hook 2 and bearing pin 5 clampings that are arranged on the returning face plate, two said bearing pins 5 are respectively in the both sides of said support torsion shaft 6.
Each said reinforcement hook 2 is installed on the suspension hook torsion shaft 1 that is fixed on the hanging beam, and two said suspension hook torsion shafts 1 are respectively in the both sides, top of said support torsion shaft 7.
Said returning face plate 6 adopts symmetrical structure, and two said limiting stoppers 8 are symmetrical set with respect to said returning face plate 6.
The roll shaft 4 that hangs fork 3 can be arranged in any groove, and install respectively after returning face plate 6 structures 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 artificial back work, has reduced labour intensity; And realized the adjusting of position accurately, improved work efficiency.
