Abstract

The utility model discloses a crane used for a lifter. The crane comprises a base, a first square steel support, a hydraulic device, a cantilever, an extensible arm and a lifting hook. The cantilever comprises a second square steel support, a first connecting lug, a third connecting lug and a hydraulic cylinder. The extensible arm comprises a third square steel support, two connecting plates, a hydraulic plunger and a connecting rod. The cantilever and the extensible arm are respectively provided with an idler wheel. Due to the fact that idler wheels are installed on the cantilever and the extensible arm, frictional force of a moving cantilever is small, energy consumption can be reduced, and at the same time the noise is low, direct contact of the cantilever and the extensible arm can be completely avoided, and therefore rusting of the cantilever and the extensible arm can be avoided.

Description

The elevator crane

Technical field

The utility model relates to a kind of crane, more precisely a kind of elevator crane.

Background technology

Base at elevator installs crane additional, can make the more convenient fast speed of user use the elevator transportation to transport goods, this crane is because the structure of cantilever and telescopic boom sliding block joint is often adopted in the restriction in space, this structure makes easier the getting rusty of part of cantilever and the mutual moving contact of telescopic boom, reduced the service life of suspended wall and telescopic boom, friction force is larger than the energy consumption of ambassador's crane, and this crane noise in the process of running is larger simultaneously.

The utility model content

The utility model mainly is to solve the existing technical matters of prior art, thereby provide on a kind of cantilever and the telescopic boom with roller, make telescopic boom friction force when motion less, reduced energy consumption, noise is also less simultaneously, can avoid cantilever directly to contact with telescopic boom fully, the elevator crane that makes cantilever and telescopic boom be difficult for getting rusty.

Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:

A kind of elevator crane, described crane comprises a base, one first square steel supporting, one hydraulic efficiency gear, one cantilever, one telescopic boom and a suspension hook, described cantilever comprises one second square steel supporting, one first engaging lug, one the 3rd engaging lug and a hydraulic actuating cylinder, described telescopic boom comprises that a third steel supports, two connecting panels, one hydraulic plunger and a pipe link, described cantilever also comprises a carriage and support roller once, described carriage is connected with the end of described the second square steel supporting, described lower support roller and described carriage are rotationally connected, the top that described third steel supports is provided with one square hole is installed, described telescopic boom also comprises a upper support roller, and described upper support roller is connected with described third steel support rotating.

As the utility model preferred embodiment, described third steel supports and contacts with described lower support roller, and described the second square steel supporting contacts with described upper support roller.

As the utility model preferred embodiment, the size of described installation square hole and described upper support roller adapt.

Therefore elevator of the present utility model with the advantage of crane is, with roller, makes telescopic boom friction force when motion less on cantilever and the telescopic boom, reduced energy consumption, noise is also less simultaneously, can avoid cantilever directly to contact with telescopic boom fully, makes cantilever and telescopic boom be difficult for getting rusty.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.

The utility model provides on a kind of cantilever and the telescopic boom with roller, make telescopic boom friction force when motion less, reduced energy consumption, noise is also less simultaneously, can avoid cantilever directly to contact with telescopic boom fully, the elevator crane that makes cantilever and telescopic boom be difficult for getting rusty.

Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of elevator crane, this crane comprise a base 1, one first square steel supporting 2, a hydraulic efficiency gear 3, a cantilever 4, a telescopic boom 5 and a suspension hook 6.

Such as Fig. 4, shown in Figure 5, this cantilever 4 comprises one second square steel supporting 41, one first engaging lug 42, one the 3rd engaging lug 43, a hydraulic actuating cylinder 46, a carriage 44 and support roller 45 once, this carriage 44 is connected with the end of this second square steel supporting 41, this lower support roller 45 is rotationally connected with this carriage 44, such as Fig. 6, shown in Figure 7, the distance that exceeds the inside face of this second square steel supporting 41 through the section of the vertex of this lower support roller 45 when cantilever 4 horizontal positioned is c, and c is greater than zero.

Such as Fig. 8, shown in Figure 9, this telescopic boom 5 comprises that a third steel supports 51, two connecting panels 52, a hydraulic plunger 53, a upper support roller 55 and pipe links 56, the top of this third steel support 51 is provided with one square hole 54 is installed, this upper support roller 55 supports 51 with this third steel and is rotationally connected, such as Figure 10, shown in Figure 11 when the telescopic boom horizontal positioned, through this upper support roller 55 to exceed the distance that this third steel supports 51 upper surfaces be d the section of vertex, and d is greater than zero.

Such as Fig. 3, Fig. 7, shown in Figure 11, under action of gravitation, the downside surface of this third steel support 51 contacts with this lower support roller 45, during the crane lifting weight, under the effect of lever, the uper side surface of this second square steel supporting 41 contacts with this upper support roller 55.

The size of this installation square hole 54 and this upper support roller 55 adapt.

Below only with an embodiment mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to simultaneously external more functional module, thereby expands to greatest extent its function.

The above only be the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
