Abstract

The utility model discloses a metallic framework structure of an escalator. The structure comprises a first metallic framework and a reinforced second metallic framework, wherein the first metallic framework is embedded into the second metallic framework and fixedly connected to the second metallic framework; and the bottom of the first metallic framework is higher than the bottom of the second metallic framework. The second metallic framework is nested outside the first metallic framework, and a double-truss metallic framework structure is realized; the double-truss metallic framework structure has the advantages of high strength and large hoisting height, is applicable to the large-span escalator and does not require a middle support, and the span can reach about 30 meters; and the double-truss metallic framework structure reduces the requirement for civil engineering, and has wide application.

Description

The metallic framework structure of escalator

Technical field

the utility model relates to the metallic framework structure of escalator.

Background technology

existing escalator adopts the mono-metallic framework as truss;, the span of escalator just needs to increase midship mounting like this when surpassing general 23 meters; To satisfy the amount of deflection requirement of metallic framework; So just increased requirement,, will cause technical trouble when on-the-spot civil engineering can't provide midship mounting and staircase span when big to civil engineering.

Summary of the invention

The purpose of the utility model provides on the escalator two truss metallic framework structures, is applicable to big span and does not have the civil engineering structure of midship mounting.

are for achieving the above object; The technical scheme that the utility model adopts is: the metallic framework structure of escalator; Comprise first metallic framework, this metallic framework structure also comprises second metallic framework of reinforcement, and said first metallic framework is embedded in said second metallic framework; And be fixedly connected on this second metallic framework, the bottom surface of said first metallic framework is higher than the bottom surface of said second metallic framework.

preferably, said second metallic framework all is fixed with brace panel in corner up and down.

preferably, said second metallic framework is on middle part roughly or on the position between end face and the bottom surface, have support, said first metallic framework is placed on the said support.

As a kind of concrete embodiment, said first metallic framework is connected on said second metallic framework through the matching and fixing of welding or bolts and nuts .

owing to the utilization of technique scheme, the utility model compared with prior art has advantage: nested second metallic framework in the outside of first metallic framework, realize two truss metallic framework structures; This pair truss metallic framework structure has the advantage of high strength, big hoisting depth; Be applicable to the staircase of big span, and need not midship mounting that span can reach about 30 meters; This pair truss metallic framework structure has reduced the requirement to civil engineering, and usability is wider.

Description of drawings

Accompanying drawing 1 is the scheme drawing of the utility model;

accompanying drawing 2 is the cutaway view Amplified image of accompanying drawing 1 along the A-A direction.

The specific embodiment

The structure of the utility model is further set forth in below in conjunction with accompanying drawing.

referring to shown in Fig. 1-2, and the metallic framework structure of escalator comprises first metallic framework 1, second metallic framework of strengthening 2; First metallic framework 1 adopts the prior standard skeleton, and second metallic framework 2 adopts steel pipe such as rectangular tube to be welded, and has rectangular tube support 3 on second metallic framework 2; First metallic framework 1 is embedded in second metallic framework 2; And be arranged on the rectangular tube support 3, rectangular tube support 3 is positioned on the middle part of second metallic framework 2, perhaps on the end face and the position between the bottom surface of second metallic framework 2; First metallic framework 1, second metallic framework 2 are after moulding separately; Splice again, first metallic framework 1 is placed on the rectangular tube support 3 of second metallic framework 2, realize that promptly first metallic framework 1 is embedded in second metallic framework 2; First metallic framework 1 is connected on this second metallic framework 2 through the matching and fixing of welding or bolts and nuts, and the bottom surface of such first metallic framework 1 is higher than the bottom surface of second metallic framework 2.Second metallic framework 2 is set; Promoted height when strengthening intensity, so two truss metallic framework structures because have high strength, the advantage of hoisting depth greatly, are about 30 meters so have the maximum outreach that the staircase of this pair truss metallic framework structure can reach with respect to existing mono-metallic framework structure; Need not midship mounting; The amount of deflection of metallic framework satisfies 1/1000 requirement simultaneously, and then this pair truss metallic framework structure has reduced the requirement to civil engineering, and usability is wider.

in order to strengthen the intensity of second metallic framework 2, and second metallic framework 2 all is fixed with brace panel 4 in corner up and down, and this brace panel 4 adopts steel plates, and is as shown in Figure 1.

First metallic framework and second metallic framework are to sum up adopted in , realize two truss metallic framework structures; This pair truss metallic framework structure is on the basis of existing metallic framework; The nested again metallic framework in the periphery, thus the intensity and the hoisting depth of metallic framework increased, be applicable to the staircase of big span; And need not midship mounting, the installation span of maximum no midship mounting can reach about 30 meters.
