Compared with the prior art, the utility model relates to the adjustable hook distance of the main hook and the auxiliary hook of the crane lifting mechanism, which can realize the hook without manual interference when the main hook and the auxiliary hook work cooperatively, and keep the auxiliary hook in a vertical state all the time, thereby avoiding the inclined pulling of the hook and the safety accident caused by the interference friction of the steel wire rope and the frame.

Description

Mechanism with lifting point capable of moving horizontally

Technical Field

The utility model belongs to the field of cranes, and particularly relates to a lifting point horizontal moving mechanism capable of enabling the hook distance of a main hook and an auxiliary hook of a crane lifting mechanism to be adjustable.

Background

The hoist often needs main auxiliary hook to overturn ladle, iron ladle, silo, material blue etc. in coordination and emptys the operation, and when adopting double-beam single dolly upset material, conventional main auxiliary hook interval is fixed, can not adjust, and the auxiliary hook can not hang the material, needs artifical couple, troublesome operation and unsafe.

In addition, the fixed structure of the distance between the main hook and the auxiliary hook can also cause the frequent interference of the steel wire rope and the danger of cutting off the steel wire rope, and the solution method adopts a four-beam double-trolley or a double-beam primary-secondary-trolley structure; the four-beam double-trolley crane has the advantages of huge structure, heavier dead weight, higher cost, higher overall height of the double-beam double-trolley crane and higher factory building construction cost.

Disclosure of Invention

The utility model aims to solve the technical problems that: how to adjust the hook distance of the main hook and the auxiliary hook without increasing the height of the whole machine, thereby providing a mechanism with a lifting point capable of moving horizontally.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

the mechanism with the lifting point capable of moving horizontally comprises a track fixed on a frame, a frame is arranged in the track in a sliding manner, one end of the frame is connected with an output rod of an electric push rod, and the electric push rod is positioned at the other end of the frame; the lifting mechanism comprises a frame, a fixed pulley block, a balance arm, a winding drum, a lifting hook pulley block, a fixed pulley block and a balance arm, wherein the fixed pulley block and the balance arm are fixed on the frame, and the steel wire rope is sequentially wound on the winding drum, the lifting hook pulley block, the fixed pulley block and the balance arm to form the lifting mechanism.

The wheel group is arranged below the frame and is arranged in the track in a sliding way through the wheel group.

Compared with the prior art, the utility model has the following advantages: the utility model relates to a crane lifting mechanism with an adjustable hook distance of a main hook and an auxiliary hook, which can realize the hook without manual interference when the main hook and the auxiliary hook work cooperatively, and keep the auxiliary hook in a vertical state all the time, so that the hook is prevented from being inclined, and the safety accident caused by interference friction between a steel wire rope and a frame is avoided.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1 and 2, a mechanism with a horizontally movable lifting point comprises a track 9 fixed on a frame, a frame 8 is slidably arranged in the track 9, one end of the frame 8 is connected with an output rod of an electric push rod 2, and the electric push rod 2 is positioned at the other end of the frame. The frame is not a part of the present utility model and is not shown in the drawings.

The mechanism of the utility model also comprises a winding drum 1 fixed on the frame, a fixed pulley block 5 and a balance arm 4 fixed on a frame 8, and a steel wire rope 6 is wound around the winding drum 1, a lifting hook pulley block 7, the fixed pulley block 5 and the balance arm 4 in sequence, thereby forming a lifting mechanism. It should be noted that, the winding manner and the connection structure of the lifting mechanism are both known in the prior art, and are well known to those of ordinary skill in the art.

Further, the wheel set 3 is arranged below the frame 8, the wheel set 3 is arranged in the track 9 in a sliding manner, the output rod of the electric push rod 2 stretches out and draws back, the frame 8 is driven to move along the track 9, and accordingly, the frame 8 drives the fixed pulley block 5 and the balance arm 4 to move, the lifting hook pulley block 7 horizontally moves, and the adjustment purpose is achieved.

The working principle of the utility model is as follows:

firstly, the fixed pulley block 5 of the hoisting mechanism and the balance arm 4 of the steel wire rope are arranged on a frame, so that the lifting hook pulley block 7 of the auxiliary hoisting mechanism is arranged on a movable frame 8, and the rest part is arranged on a fixed frame. The frame 8 is supported by the wheel set 3, the movement of the frame depends on an electric push rod connected with the frame, and along with the action of the electric push rod, the frame 8 drives the fixed pulley block 5 and the balance arm 4 to move, so that the auxiliary hook can move along with the movement of the lifting hook pulley block 7, and the adjustment of the lifting hook distance is realized. The structure has compact layout and reliable use, can not increase the height of the whole machine, and is a solution for realizing the adjustment of the space between the lifting hooks.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
