Abstract

The utility model relates to a crane, in particular to a bridge crane with a rotary clamp. The utility model aims at solving the technical problems that the conventional crane is complex in the structure, high in production cost and difficult to assemble and maintain, and the crane cannot be used for clamping cargo. The bridge crane comprises a crane span (1) arranged on the walls at both sides, wherein the lower parts of both ends of the crane span (1) are connected with a crane operating mechanism (2); the crane operating mechanism is glidingly connected on the walls at both sides; the crane span (1) is provided with a guide rail (3) which is glidingly connected with more than two traveling trolleys (4); and the traveling trolleys are connected with a rotary clamp (5) through a rope.

Description

A kind of rotation clamp crane in bridge type

Technical field

The utility model relates to a kind of hoisting crane, especially relates to a kind of rotation clamp crane in bridge type.

Background technology

Weight-lifting equipment is divided into transfer crane, crane in bridge type, beam crane and boom crane by device structure; Wherein transfer crane mainly representative equipment be gauntry crane; Crane in bridge type mainly representative equipment is the bridge formation machine, and boom crane mainly representative equipment is a tower crane.Transfer crane is mainly used in work operations such as the up-down, parallel motion of building ground, factory floor and shipyard harbour weight.Transfer crane mainly is made up of lifting overhead traveling crane, girder, supporting leg, traveling gear and electric hydraulic system.Its principle of work is: utilize the lifting overhead traveling crane that is installed on the girder that weight is raised up; The supporting leg upper end connects girder; The lower end connects with traveling gear, through being installed in the driving of motor on the traveling gear, realizes the effect that hoisting crane moves on rail; The overhead traveling crane of lifting simultaneously also can be walked on girder, realizes at last weight is hung the effect that moves on to another place from a place.But the structure of these hoisting cranes is comparatively complicated, and productive costs is higher, and assembling is built, keeps in repair also comparatively difficult, and hoisting crane can only lift goods with suspension hook, can't the clamping goods.

The utility model content

The utility model provides a kind of rotation clamp crane in bridge type; It mainly is that to solve the structure of existing in prior technology hoisting crane comparatively complicated; Productive costs is higher; Assembling is built, keeps in repair also comparatively difficult, and hoisting crane can only lift goods with suspension hook, technical matters that can't the clamping goods etc.

The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:

A kind of rotation clamp crane in bridge type of the utility model; Comprise the crane span structure that is erected on the body of wall of both sides; The bottom at described crane span structure two ends all is connected with a crane travel mechanism, and crane travel mechanism is slidingly connected on the body of wall of both sides, and crane span structure is provided with guide rail; Slidely connect two above travelling cars on the guide rail, connect the rotation clamp through rope on the travelling car.

As preferably, described crane span structure is connected with stair.

Therefore, the utility model is relatively simple for structure, and clamp is set on travelling car, can carry out clamping to goods, and the assembling, the maintenance all more or less freely, productive costs is lower.

Description of drawings

Accompanying drawing 1 is a kind of structural representation of the utility model.

The specific embodiment

Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.

Embodiment: a kind of rotation clamp crane in bridge type of this example; Like Fig. 1, comprise the crane span structure 1 that is erected on the body of wall of both sides, the bottom at crane span structure two ends all is connected with a crane travel mechanism 2; Crane travel mechanism is slidingly connected on the body of wall of both sides; Crane span structure is provided with guide rail 3, slidely connects two above travelling cars 4 on the guide rail, connects rotation clamp 5 through rope on the travelling car.Crane span structure is connected with stair 6.

The above is merely the specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.

Claims

1. rotation clamp crane in bridge type; Comprise the crane span structure (1) that is erected on the body of wall of both sides; The bottom that it is characterized in that described crane span structure (1) two ends all is connected with a crane travel mechanism (2), and crane travel mechanism is slidingly connected on the body of wall of both sides, and crane span structure (1) is provided with guide rail (3); Slidely connect two above travelling cars (4) on the guide rail, connect rotation clamp (5) through rope on the travelling car.
