Abstract

The utility model provides a gantry hook capable of adjusting hook distance manually. The gantry hook comprises a gantry hook beam and a shaft pin, wherein arc-shaped shaft pin slide ways are arranged at two hanging points of the gantry hook beam; adjustment devices are arranged at the two ends of the gantry hook beam. The gantry hook capable of adjusting the hook distance manually has the beneficial effects that the hook distance can be adjusted conveniently without increasing a crane or replacing the gantry hook by adding a manual spiral adjustment device, so that the requirements on hoisting and transporting steel ladles and iron ladles of different specifications of a user are met; moreover, the gantry hook capable of adjusting the hook distance manually is simple in structure, easy to manufacture, and convenient to use; the input cost is reduced; the work efficiency is improved.

Description

A kind of gantry hook that can manual regulation hook distance

Technical field

The utility model relates to the special hanger apparatus field of steel mill or foundry plant's handling steel ladle or ladle, particularly a kind of gantry hook that can manual regulation hook distance.

Background technology

At present, gantry hook is the special hanger of steel mill or foundry plant's handling molten iron and steel ladle.Conventional gantry hook is that as the distance of L1 and L2 in (Fig. 1), but this distance is unadjustable according to the distance that needs the hanger spacing design plate hook of handling steel ladle or ladle, steel ladle or ladle that can only a kind of specification of handling.But the size of steel ladle and ladle is often different, so just need to adopt different gantry hooks to carry out handling.At present steel mill generally adopts steel ladle and the ladle that realizes handling different size with two hoisting cranes of different suspenders or the method for changing suspender.The former need increase the investment of a hoisting crane, and input cost is larger, and the latter also needs to increase suspender and changes suspender and comparatively bothers, and causes operation and uses inconvenience.

Therefore, the utility model is to develop on the basis that mainly solves more than currently available technology existence deficiency.

Summary of the invention

The object of utility model is to solve above technical matters, proposes especially a kind of manually free adjustment hook apart from, reduction input cost, gantry hook easy to use.

Based on above-mentioned purpose, the technical matters that the utility model solves realizes by the following technical solutions:

Gantry hook that can manual regulation hook distance, comprises gantry hook crossbeam, pivot pin, and two sling point places of described gantry hook crossbeam are provided with circular arc pivot pin slideway, and the place, two ends of gantry hook crossbeam is provided with control apparatus.

Further, the nut of doing motion of translation in described control apparatus is connected with the pivot pin Y-piece of hanging plate hook.

Further, described control apparatus is for manually spiral.

Further, described control apparatus, by hand rotation, drives the pivot pin of hanging plate hook to move.

The beneficial effects of the utility model are, by increasing manual spiral control apparatus, can adjust easily hook distance not increasing hoisting crane or not changing under the condition of gantry hook, realize the requirement of user's handling different size steel ladle and ladle; And simple in structure, be easy to manufacture, reduced again input cost, convenient use, has improved work efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of plate hook;

In figure, 1. gantry hook crossbeam, 2. pivot pin, 3. control apparatus, 4. pivot pin slideway, 5. pivot pin Y-piece, 6. plate hook.

The specific embodiment

Below, by Figure of description, further set forth the utility model;

Shown in Fig. 1, Fig. 2, a kind of gantry hook that can manual regulation hook distance, comprise gantry hook crossbeam 1, pivot pin 2, two sling point places of gantry hook crossbeam 1 are provided with circular arc pivot pin slideway 4, place, two ends at gantry hook crossbeam 1 arranges manual spiral regulating device 3, the nut of making motion of translation in this device is connected with the pivot pin Y-piece 5 of hanging plate hook, by hand rotation spiral regulating device 3, pivot pin 2 motions that plate hook is hung in drive realize the movement of plate hook 6, thereby realize gantry hook, are changed to the roll adjustment of L2 by two plate hook spacing L1.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
