Abstract

The utility model discloses a lift car bottom structure, comprising a car bottom plate, a car bottom front beam, a car bottom rear beam and at least a car bottom beam. The car bottom front beam, the car bottom rear beam and the car bottom beam form the supporting surface of the car bottom plate; and not less than two car bottom plates are provided, and a detachable structure is used for connection between the car bottom plates, between the car bottom plate and the car bottom front beam, between the car bottom rear beam and the car bottom beam. The above car bottom front beam, car bottom rear beam and car bottom beam are parallel with each other and not less than two of the above car bottom beams are provided. The above detachable structure is a bolt-hole connecting structure. Relative to the prior art, the utility model is characterized by easy installation and transport, low processing precision requirement and reduced overall elevator cost.

Description

A kind of elevator sedan-chair bottom structure

Technical field

The utility model belongs to the elevator structure technical field, is specifically related to a kind of elevator sedan-chair bottom structure.

Background technology

In lift car sedan-chair frame, belong to main load bearing component at the bottom of the sedan-chair, adopt all-in-one-piece monolithic sedan-chair base arrangement at present usually.But for the elevator of ultra-large type Cargo Lift one class, because loaded area is big, loading strength is had relatively high expectations, if still adopt integral type monolithic sedan-chair bottom structure, bring problems then can for the aspects such as manufacturing, vanning, transportation and on-site installation at the bottom of the elevator sedan-chair because of the volume and weight of sedan-chair base plate is excessive.

Summary of the invention

The purpose of this utility model is at the problems referred to above, a kind of elevator sedan-chair bottom structure simple in structure is provided, not only solve the problem of aspects such as manufacturing at the bottom of the ultra-large type elevator sedan-chair, transportation, on-site installation, also reduced the cost of the links such as manufacturing, transportation and installation at the bottom of the ultra-large type elevator sedan-chair.

For achieving the above object, the technical solution of the utility model is as follows: a kind of elevator sedan-chair bottom structure comprises the sedan-chair base plate; Also comprise at the bottom of front-axle beam at the bottom of the sedan-chair, the sedan-chair bottom girder at the bottom of the back rest and at least one sedan-chair, at the bottom of the sedan-chair at the bottom of front-axle beam, the sedan-chair at the bottom of the back rest and the sedan-chair bottom girder constitute sedan-chair backplanes support face; And described sedan-chair base plate has and is no less than two, and between the sedan-chair base plate, adopt the connection of detouchable structure between sedan-chair base plate and the bottom girder at the bottom of the back rest at the bottom of front-axle beam, the sedan-chair at the bottom of the sedan-chair and the sedan-chair.

At the bottom of the above-mentioned sedan-chair at the bottom of front-axle beam, the sedan-chair at the bottom of the back rest and the sedan-chair bottom girder be parallel to each other.

Bottom girder is for being no less than two at the bottom of the above-mentioned sedan-chair.

Above-mentioned detouchable structure is bolt-hole connection structure.

The utility model is by adopting said structure, the spacing that only needs to guarantee the mounting hole on the front and rear beam at the bottom of bottom girder at the bottom of the sedan-chair, the sedan-chair just can solve the not enough problem of accuracy of manufacture at the bottom of the large tracts of land sedan-chair, and since between the sedan-chair base plate, at the bottom of sedan-chair base plate and the sedan-chair at the bottom of bottom girder, the sedan-chair between the front and rear beam employing detouchable mode connect, therefore take apart respectively at the bottom of can be when vanning, transportation and on-site installation and case, transport and install, solved the problem of manufacturing, transportation and installation at the bottom of the ultra-large type Cargo Lift sedan-chair sedan-chair.The utility model has the advantage that installation and transportation are convenient, requirement on machining accuracy is low and reduce the whole cost of elevator with respect to prior art.

Description of drawings

Fig. 1 is the front view of an embodiment of the utility model;

Fig. 2 is the birds-eye view of Fig. 1.

Below in conjunction with drawings and Examples the utility model is further specified:

The specific embodiment

As depicted in figs. 1 and 2, elevator sedan-chair bottom structure described in the utility model comprises at the bottom of the sedan-chair at the bottom of front-axle beam 1, the sedan-chair bottom girder 3 and two block-shaped equirotal sedan-chair base plates 4 at the bottom of the back rest 2, two sedan-chairs.At the bottom of the sedan-chair at the bottom of front-axle beam 1, the sedan-chair at the bottom of the back rest 2 and two sedan-chairs bottom girder 3 be parallel to each other and constitute sedan-chair backplanes support face.Two sedan-chair base plates 4 be combined at the bottom of the sedan-chair and sedan-chair base plate 4 between, adopt detouchable bolt-hole connection structure 5 to connect between the bottom girder 3 at the bottom of the back rest 2 and the sedan-chair at the bottom of front-axle beam 1, the sedan-chair at the bottom of sedan-chair base plate 4 and the sedan-chair.

At the bottom of the sedan-chair of the present utility model at the bottom of front and rear beam, the sedan-chair bottom girder, sedan-chair base plate can case separately and transport, at the scene the splicing.

The utility model also is applicable to common elevator except being applicable to the ultra-large type Cargo Lift, as passenger elevator, Cargo Lift, car elevator etc.
