Abstract

The utility model discloses a bridge crane with the guiding and the lifting functions, which comprises a main beam, a hanging hook and a motor. A guide rail is mounted under both sides of the main beam; a sliding trolley is placed in the guide rail; the hanging hook is fixed on the sliding trolley; the motor drives the sliding trolley to vertically lift along the guide rail, and is provided with a chain or a belt; the sliding trolley is lifted at one end of the chain or the belt, and a counterweight is lifted at the other end. The bridge crane has the advantages of simple structure and stable lifting.

Description

The crane in bridge type that has the elevating function that leads

Technical field:

The utility model relates to a kind of crane in bridge type that has the elevating function that leads.

Background technology:

When metal product being carried out pickling, oxidation or electroplating, all need to utilize crane in bridge type handling institute converted products, traditional crane in bridge type is owing to utilize steel rope lifting, hung product and be easy to generate and rock in the process of lifting or hoisting crane operation, has potential safety hazard.

Summary of the invention:

The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of crane in bridge type that operates steadily to be provided.

For achieving the above object, the technical scheme that the utility model provides is: the crane in bridge type that has the elevating function that leads, include girder, hook and motor, down either side at girder is equipped with guide rail, in guide rail, be placed with sliding machine, hook is fixed on the sliding machine, and the motor-driven sliding machine is along the guide rail oscilaltion.

Motor has chain or belt, the end lifting sliding machine of chain or belt, and on the other end, be lifted with clump weight.

After adopting technique scheme, the oscilaltion campaign of hook is subjected to the restriction of guide rail all the time, and can not occur rocking, and increases the safety of producing.

Description of drawings:

Fig. 1 is the front elevation of the utility model crane in bridge type;

Fig. 2 is the lateral plan of the utility model crane in bridge type;

Fig. 3 is the birds-eye view of the utility model crane in bridge type;

Fig. 4 is the sectional structure chart of a side rails of the utility model crane in bridge type.

The specific embodiment:

Now 1～Fig. 4 elaborates the utility model in conjunction with the accompanying drawings:

Girder 1 both sides of this crane in bridge type all are equipped with guide rail 2; in the guide groove of guide rail 2, be placed with sliding machine 3; the a pair of hook 4 of fixed installation before and after on sliding machine 3; between the hook 4 on the same sliding machine 3 cross bar 5 is installed; mount framed bent 6 between the cross bar of both sides; above the cooresponding guide rail 2 motor 7 is being installed on the girder 1; two chains 8 on the gear wheel shaft of this motor 7, have been mounted; one end of every chain is connected with sliding machine 3; other end lifting clump weight 9; the effect of weight equalizer and protection motor 7 is played in the existence of clump weight 9, cocoa.

Above-mentioned chain 8 also can change belt into, equally can realize the purpose of this utility model.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
