Description
Technical Field
The utility model belongs to the technical field of the hoist, a bridge crane is from locking-type wire rope handling lifting hook is related to.
Background
Crane hook is the connecting piece that hangs the jack-up heavy object, it is light to have the dismouting, safe and reliable's technical requirement, because bridge crane drives the vertical in-process that takes off and land or pass through the dolly translation on the bridge at the electric hoist of heavy object, the lifting hook bearing receives the certain impact force of heavy object, the wholeness of lifting hook seriously influences the wholeness ability of hoist, current lifting hook breaks away from the restriction rope mostly through the spring bolt, and the rope is located the drunkenness that has certain range in the lifting hook, the reliability of spring bolt is difficult to the guarantee, therefore it is higher to need a security, the more light lifting hook structure of dismouting.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that exists to current technique, provide a bridge crane from locking-type wire rope handling lifting hook, the utility model aims to solve the technical problem that how make the lifting hook have anticreep self-locking function.
The purpose of the utility model can be realized by the following technical proposal: a self-locking rope threading lifting hook of a bridge crane is characterized by comprising an installation block, a locking plate, two bearing hooks and a synchronous hook, wherein one end of the synchronous hook is fixedly connected with the locking plate, a first inlet is formed between the other end of the synchronous hook and the lower end face of the locking plate, the locking plate is longitudinally connected onto the bearing hooks in a sliding manner, and a second inlet is formed between the bearing hooks and the locking plate; in the process that the synchronous hook is close to the bearing hook, the second inlet can be closed due to the fact that the locking plate is close to the bearing hook.
Further, the bearing hook comprises a bending portion at the middle part, a guiding connecting portion and an inserting portion, the guiding connecting portion is located at one end of the bending portion, the inserting portion is located at the other end of the bending portion, the guiding connecting portion and the inserting portion are both vertical rod-shaped, the installation block is fixedly connected with the guiding connecting portion, a sliding hole corresponding to the guiding connecting portion is formed in the locking plate, and a jack corresponding to the inserting portion is formed in the locking plate.
The lantern ring of the rope that can be connected the heavy object passes through second entry and first entry, makes the rope be located between lock plate and two bearing hooks, and then, under the effect of heavy object, colludes down in step, makes the lock plate also down, enters the shutoff with the second, and then realizes spacing, automatic spacing promptly of many ropes.
When the lantern ring of the rope is taken out, the heavy object of the rope is taken out, the locking plate is pushed upwards, and the lantern ring of the rope can be taken out easily through the first inlet and the second inlet.
In this scheme, under the locking state, because the direction connecting portion and the grafting portion of bearing hook all receive the spacing of lock plate, the bearing hook is anti deformability stronger, compares traditional lifting hook, and reliability and security are higher, and is spacing firm reliable to the rope when bridge crane lifts by crane the translation of heavy object.
A certain gap is formed between the synchronous hook and the two bearing hooks, so that the rope has certain buffering capacity in the process of bearing the weight, and the impact force in the process of partial lifting is overcome.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, 2, 3 and 4, the self-locking rope threading hook of the bridge crane comprises a mounting block 1, a locking plate 2, two bearing hooks 3 and a synchronous hook 4, wherein one end of the synchronous hook 4 is fixedly connected with the locking plate 2, a first inlet is formed between the other end of the synchronous hook 4 and the lower end surface of the locking plate 2, the locking plate 2 is longitudinally and slidably connected to the bearing hooks 3, and a second inlet is formed between the bearing hooks 3 and the locking plate 2; during the approach of the synchronization hook 4 to the load-bearing hook 3, the second inlet can be closed by the approach of the locking plate 2 to the load-bearing hook 3.
The bearing hook 3 includes the flexion 31 at middle part, is located the direction connecting portion 32 of flexion 31 one end and is located the grafting portion 33 of the 31 other end of flexion, and direction connecting portion 32 and grafting portion 33 are vertical shaft-like, and the installation piece 1 links to each other with the direction connecting portion 32 is fixed, has seted up the slide opening that corresponds with direction connecting portion 32 on the lock plate 2, has still seted up the jack 21 that corresponds with grafting portion 33 on the lock plate 2.
The lantern ring of the rope that can be connected the heavy object passes through second entry and first entry, makes the rope be located between locking plate 2 and two bearing hooks 3, and then, under the effect of heavy object, colludes down in step, makes locking plate 2 also down, with the shutoff of second entry, and then realize spacing, automatic spacing promptly of many ropes.
When the lantern ring of the rope is taken out, the heavy object of the rope is taken out, the locking plate 2 is pushed upwards, and the lantern ring of the rope can be taken out easily through the first inlet and the second inlet.
In this scheme, under the locking state, because the direction connecting portion 32 and the grafting portion 33 of bearing hook 3 all receive the spacing of lock plate 2, the anti deformability of bearing hook 3 is stronger, compares traditional lifting hook, and reliability and security are higher, and is spacing firm reliable to the rope when bridge crane lifts by crane the translation of heavy object.
A certain gap is formed between the synchronous hook 4 and the two bearing hooks 3, so that the rope has certain buffering capacity in the process of bearing weight, and the impact force in the process of partial lifting is overcome.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
