Abstract

The utility model relates to a bidirectional shaking-proof device for crane, comprising a lift mechanism with a lift roller, lift ropes winding on the lift roller and a hanging device or a hanging support which can be used to arrange the lift ropes on. Four same inverse equilateral triangles are formed by the winding ways of the lift ropes; the lift ropes are formed into four inverse equilateral triangles on the four vertical faces between the dolly and the hanging device through the lift roller and pulleys; the four inverse equilateral triangles are equal; the number of the lift ropes which are formed into four inverse equilateral triangles is eight or a multiple of eight. The bidirectional shaking-proof device for crane of the utility model uses geometry principle to realize shaking-proof and truck contraposition functions of tyre type container gantry crane or track type container gantry crane at the two directions of big car and small car, the loading efficiency of crane is enhanced to form a firm base for automatization.

Description

The two-way anti roll device of hoisting crane

Technical field

The utility model relates to elevator machinery, the two-way anti roll device on particularly a kind of rubbertyred container gantry crane (RTG) or track type container large scale crane (RMG) and other the similar hoisting crane.

Background technology

Flourish along with the international container transport cause, container depot especially require more and more higher as the container depot in freight container single user wharf to the efficient of equipment, degree of automation, fault rate etc.Rubbertyred container gantry crane or track type container large scale crane be as the main loading-unload machine of container depot, its mainly act on be with freight container in the stockyard access efficiently operate.Reach this target, it then is crucial controlling promptly anti-the shaking of shaking of suspender effectively.

The steel rope canoe of traditional rubbertyred container gantry crane (RTG) or track type container large scale crane lifting main liftings such as (RMG), vertical dolly of hoisting crane or laterally the cart service direction owing to can not suppress lifting spreader and freight container waving at this both direction, therefore must add a cover mechanical type or a fluid pressure type anti-sway system in addition, yet the complex structure of this cover system, fault rate is higher, and the anti-effect of shaking is also undesirable.The driver needs the expensive time to casing working the time, thereby has caused the decline of whole handling efficiency.Have only quite skilled driver situation of waving of control sets vanning to some extent when operation, even and to the cart service direction to wave very skilled driver also powerless.

Along with the continuous development of industrial technology and improving constantly of terminal operation amount, at present a lot of harbours all wish to realize the semi-automatic or full-automatic of rubbertyred container gantry crane and track type container large scale crane and other similar hoisting crane, to adapt to the continuous development of freight container traffic industry.Traditional canoe of rubbertyred container gantry crane or track type container large scale crane and other similar hoisting crane, owing to can't suppress lifting spreader and freight container effectively the waving of cart, dolly both direction, therefore realize rubbertyred container gantry crane or track type container large scale crane and other similar hoisting crane semi-automatic or full-automatic aspect become difficult.

Summary of the invention

Task of the present utility model provides the two-way anti roll device of a kind of hoisting crane, and it has solved above-mentioned prior art and has caused complex structure, fault rate problem of higher and the traditional canoe problem of waving at cart, dolly both direction at installation mechanical type or fluid pressure type plane rotation device.

The technical solution of the utility model is as follows:

The two-way anti roll device of a kind of hoisting crane, it comprises the lifting mechanism that hoisting drum is housed, be wound in the raising line on the hoisting drum, and suspender or suspender that raising line is installed on it are put on the shelf, the canoe of described raising line forms four identical equilateral dels, raising line twines the equilateral del of formation respectively by hoisting drum and pulley on four vertical surface between dolly and the suspender, four dels equate that the raising line that forms four dels is provided with eight or eight multiples.

The two-way anti roll device of hoisting crane of the present utility model utilizes geometrical principle to realize that rubbertyred container gantry crane or track type container large scale crane and other similar hoisting crane shake and the truck contraposition the anti-of cart, dolly both direction, improved the handling efficiency of rubbertyred container gantry crane or track type container large scale crane and other similar hoisting crane, for automated job has been laid sturdy basis.

Anti roll device of the present utility model utilizes geometrical interference locking single pendulum to make it the principle that can not swing at cart and dolly both direction, change traditional raising line winding system the system of four identical dels into, promptly steel rope has four identical dels on dolly and suspender four faces perpendicular to the ground.When the suspender lifting, shape can change in each triangle, but four triangles are still equal fully, make suspender all be in a kind of highly stable state, thereby realize the rocking-prevention function that the suspender of rubbertyred container gantry crane or track type container large scale crane and other similar hoisting crane and freight container all have at dolly or cart service direction at cart and dolly both direction.

Description of drawings

Fig. 1 is the structural representation of the two-way anti roll device of a kind of hoisting crane of the present utility model.

Fig. 2 is by left view shown in Figure 1.

Fig. 3 is that the raising line of the two-way anti roll device of Fig. 1 hoisting crane twines scheme drawing.

The specific embodiment

Referring to Fig. 1 to Fig. 3, the two-way anti roll device of a kind of hoisting crane of the present utility model comprises the lifting mechanism that hoisting drum 1 is housed, and is wound in the raising line on the hoisting drum 1, and suspender 2 or suspender that raising line is installed on it are put on the shelf.

Raising line 3 in the utility model anti roll device twines and is installed between hoisting drum 1 and suspender 2 or suspender put on the shelf, four identical equilateral dels of its canoe formation, and the summit of equilateral del is downward.Raising line 3 twines the equilateral del of formation respectively by hoisting drum 1 and pulley 4 on four vertical surface between pulley 4 and the suspender 2, four dels equate.The raising line 3 that forms four dels is provided with eight or eight multiples, and when the suspender lifting, the shape of equilateral del can change, but the shape of four dels keeps equal.The geometrical interference principle of utilizing the utility model realizes that suspender shakes with the cart and the anti-of dolly both direction of freight container at rubbertyred container gantry crane or track type container large scale crane and other similar hoisting crane, can suppress suspender and freight container well and play waving of glancing impact at cart and dolly.

Hoisting drum 1 can be provided with one or two in lifting mechanism, be used for twining raising line 3.Label 5 is little thrust units that move among Fig. 1, and label 6 is the setting devices of rope 3 tensioning length of adjusting hoisting, and label 7 is slippage guide rails, and label 8 is to the crane overload protection and the weight sensor of weighing.

Claims

1. two-way anti roll device of hoisting crane, it comprises the lifting mechanism that hoisting drum is housed, be wound in the raising line on the hoisting drum, and suspender or suspender that raising line is installed on it are put on the shelf, it is characterized in that, the canoe of described raising line forms four identical equilateral dels, raising line twines the equilateral del of formation respectively by hoisting drum and pulley on four vertical surface between dolly and the suspender, four dels equate that the raising line that forms four dels is provided with eight or eight multiples.
