Description

Automatic stable balance system for crane hoisting

Technical Field

The utility model relates to a driving technical field especially indicates a simple structure, convenient to use's automatic stable balanced system.

Background

Travelling cranes, also called as navigation cranes, gantry cranes and overhead traveling cranes, are a general name of cranes, and the driving modes of the travelling cranes are basically the same as those of the gantry cranes and the bridge cranes, namely, one type of the travelling cranes is driven in a centralized mode and the other type of the travelling cranes is driven in a separate mode.

The common traveling crane in the prior art is a bridge crane, also called a beam crane, which is a hoisting device that is transversely arranged above a workshop, a warehouse and a stock yard to hoist materials. Since its two ends are seated on a tall concrete column or a metal bracket, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated frames at two sides, so that the space below the bridge frame can be fully utilized to hoist materials without being hindered by ground equipment. The lifting machine has the widest application range and the largest quantity.

The bridge crane can carry out hoisting operation within a specified operation range, and the production efficiency is greatly improved. However, the existing bridge crane generally has the defect that when the goods are hoisted, the goods are easy to swing left, right, front and back due to self gravity, and particularly when the traveling crane starts and stops, the goods swing under the action of self inertia, so that the operation is not facilitated, the goods cannot be accurately and quickly hoisted to a designated place, and the potential safety hazard exists in the second aspect.

SUMMERY OF THE UTILITY MODEL

The utility model provides a driving hoist and mount automatic stable balanced system has solved among the prior art problem that the goods easily takes place the wobbling when driving hoist and mount.

The technical scheme of the utility model is realized like this: the automatic stabilizing and balancing system for crane hoisting comprises an electric hoist, wherein a lifting hook is suspended below the electric hoist through a steel wire rope, a remote control device for controlling the electric hoist to move is arranged on the electric hoist, a position indicator synchronously moving with the electric hoist is further arranged on the electric hoist, the position indicator projects an indicating aperture to the ground, and the indicating aperture is positioned right below the lifting hook;

and the electric hoist is also provided with a control mechanism for sensing the position relation between the electric hoist and the goods and sending an instruction to the electric hoist.

In a preferred embodiment, the control mechanism comprises

The angle sensor is used for sensing an included angle between the steel wire rope and the vertical line;

As a preferred embodiment, the control mechanism further comprises a gyroscope and a balance sensor for sensing the balance state of the electric hoist, and the gyroscope and the balance sensor also transmit the sensed data to the data calculation module.

In a preferred embodiment, the position indicator is a laser transmitter.

After the technical scheme is adopted, the beneficial effects of the utility model are that: the utility model discloses a driving hoist and mount automatic stable balanced system passes through the instruction light ring that position indicator throws to ground and can be accurate, hoist the goods to appointed position top fast, after the goods reachs appointed position, the staff utilize remote control unit slowly put down the lifting hook can. In goods hoist and mount in-process, the control mechanism of installation can respond to the position relation between electric block and the goods and send the instruction to electric block, be used for offsetting, compensate the swing problem because of goods inertia effect produces, for example, after electric block reachs the assigned position, the goods still can move a section distance forward because of inertia effect, at this moment, in order to avoid the swing of goods consequently production, control mechanism calculates the distance that reachs electric block and should move forward according to the data that senses, and then control electric block moves certain distance forward again, make electric block and goods stop simultaneously, the swing phenomenon of goods has been avoided.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example (b):

as shown in fig. 1, do the utility model discloses driving hoist and mount automatic stabilization balance system's an embodiment, it includes electric block 1, has hung lifting hook 3 through wire rope 2 in electric block 1's below, is equipped with remote control unit 4 that is used for controlling its removal on electric block 1, and above-mentioned structure is comparatively common driving structure among the prior art, no longer gives redundant details here.

The electric hoist 1 is also provided with a position indicator 5 which moves synchronously with the electric hoist, the position indicator 5 preferably uses a laser transmitter which can project an indicating aperture 7 to the ground, and the indicating aperture 7 is just below the lifting hook 3, so that before the electric hoist is used, the direction of the position indicator 5 needs to be set according to the height of the electric hoist 1 and the position of the lifting hook 3.

In addition, a control mechanism is also installed on the electric hoist 1, and the control mechanism is a core component of the whole balance system and mainly comprises an angle sensor 8, a speed sensor 9 and a data calculation module 10, wherein the angle sensor 8 is used for sensing an included angle between the steel wire rope 2 and a vertical line, for example, the angle shown in fig. 1 is 0 °, and when the electric hoist 1 is started or braked, the steel wire rope 2 is inclined under the inertia effect of goods on the hook 3, and the included angle between the steel wire rope 2 and the vertical line is not 0 °. The speed sensor 9 is used for sensing the moving speed of the electric hoist 1 and the goods.

The angle sensor 8 and the speed sensor 9 can also transmit the sensed data to the data calculation module 10 in real time, and the data calculation module 10 is used for processing the received data and sending an instruction to the electric hoist 1 according to a processing result so as to control the action of the electric hoist 1. For example, when the data calculation module 10 determines that the cargo still continues to move forward for a distance under the action of its own inertia according to the calculated data, the electric hoist 1 is controlled to correspondingly move forward for a distance, and the moving distance is consistent with the calculated moving distance of the cargo, so as to ensure that the electric hoist 1 is just above the cargo when the cargo stops, thereby avoiding the swinging phenomenon of the steel wire rope 2 and the cargo.

Finally, the control mechanism in this embodiment may further include a gyroscope and a balance sensor (not shown in the drawings) for sensing the balance state of the electric block 1, and the gyroscope and the balance sensor can also transmit the sensed data to the data calculation module.
