In order to solve the problems existing in the background, the utility model aims to provide a novel overhead traveling crane gib head mousing-hook device.

The technical scheme of the utility model as follows: a novel overhead traveling crane hook head unhooking prevention device comprises a lifting hook, a pulley block, a clamping seat, a stud device and a hoop; the lifting hook is connected with the pulley block; the stud bolt device comprises a stud bolt column, a nut and a gasket; the clamping seat, the hoop and the gasket are provided with through holes; the stud bolt device is connected with the clamping seat and the hoop through the through hole; the anchor ear is connected with the lifting hook through a stud bolt device; the clamping seat is connected with the lifting hook through the stud bolt device and the hoop.

The sizes of the through holes of the anchor ear and the gasket are matched with the size of the stud column.

The diameter of the through hole of the clamping seat is larger than the diameter of the stud column.

The hoop is a U-shaped hoop.

The clamping seat is -shaped.

The card seat is provided with a warning sign.

From the above description of the present invention, compared with the prior art, the advantages of the present invention lie in: 1. the utility model discloses a sky car gib head anticreep device has certain weight can reduce because of the lifting rope that hangs the bullet, hangs thing pause ground and cause string rope or stereoplasm hoist crosspiece, and takes place to hang the rope or the incident that the hoist breaks away from the gib head and arouses.

2. The utility model discloses an installation of overhead traveling crane gib head anticreep device does not need the lifting hook to have the mounting hole, makes lifting hook live time increase, reduces the lifting hook and changes the number of times, improves work efficiency.

3. The utility model discloses a difficult emergence after overhead traveling crane gib head anticreep device uses is out of shape, reduces and changes the number of times, improves work efficiency.

4. The utility model discloses a be equipped with warning mark on overhead traveling crane gib head anticreep device's the cassette, help the overhead traveling crane driver in time to discover the situation that lifts by crane the in-process and appear to in time park and inform relevant personnel to handle, prevent that the occurence of failure or incident from expanding.

In fig. 1 to 5: the device comprises a lifting hook 1, a pulley block 2, a clamping seat 3, a hoop 4, a double-end bolt column 5, a nut 6, a gasket 7, a warning mark 8, a long and thin push rod 9, a gantry hook group 10 and a slab tundish 11.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Referring to the attached drawings 1-5, the novel crown block gib head unhooking prevention device comprises a lifting hook 1, a pulley block 2, a clamping seat 3, a stud bolt device and a hoop 4, wherein the lifting hook 1 is connected with the pulley block 2, the stud bolt device comprises a stud bolt column 5, a nut 6 and a gasket 7, the clamping seat 3, the hoop 4 and the gasket 7 are respectively provided with a through hole, the size of the through holes of the hoop 4 and the gasket 7 is matched with that of the stud bolt column 5, the aperture of the through hole of the clamping seat 3 is larger than the diameter of the stud bolt column 5, the stud bolt device is connected with the clamping seat 3 and the hoop 4 through the through holes, the hoop 4 is connected with the lifting hook 1 through the stud bolt device and the hoop 4, the hoop 4 is a U-shaped hoop, the clamping seat 3 is -shaped, and the clamping seat 3 is provided with a warning mark.

The utility model discloses equipment and application method as follows:

assembling: insert 1 neck department of lifting hook with staple bolt 4 opening earlier, then the stud post passes staple bolt 4 through-holes, utilizes nut 6, gasket 7 to be fixed in 1 neck department of lifting hook with staple bolt 4, sheathes cassette 3 in the both sides of stud post 5 at last, fixes with nut 6, makes cassette 3 and stud post 5 be rotatable coupling.
