Abstract
The utility model relates to the field of bridge engineering construction technology, in particular to a wide-angle swinging and hoisting hydraulic cable-across crane which comprises a running mechanism, a main girder structure, a lifting jack and lifting steel strands. The running mechanism is arranged on a main cable of a suspension bridge, and the main girder structure is connected with the running mechanism through a pin shaft in hinged mode. The lifting steel strands internally penetrate in the lifting jack and are clamped by the lifting jack. The wide-angle swinging and hoisting hydraulic cable-across crane is characterized in that the lifting jack is in hinge connection with the main girder structure. The wide-angle swinging and hoisting hydraulic cable-across crane is simple in structure, convenient and practical, enables the lifting steel strands to be always in a straight line state and has best bearing effect in the swinging process, and ensures hoisting operation to go on safely.
Description
Technical field
The utility model relates to the Bridge Construction technical field, refers to that particularly a kind of wide-angle swings the fluid pressure type that moves lifting and stride the cable loop wheel machine.
Background technology
Striding the cable loop wheel machine is the Main Hoisting Machinery of suspension bridge steel case beam lifting operation, stride cable loop wheel machine lifting steel case beam and be generally the vertical lifting operation, but in the Practical Project, also there is vertical lifting can't satisfy construction requirement, need to strides the cable loop wheel machine and carry out certain angle and swing the situation of moving operation.Traditional fluid pressure type is striden the cable loop wheel machine and is all adopted the mode of " main beam structure and walking structure are articulated and connected " to address this problem, but because of deck unit erection gantry girder system weight large, swing when moving lifting operation, the girder system often is difficult to carry out flexible rotating along promoting steel strand, so that form the knuckle of certain angle between main beam structure and the lifting steel strand, cause very adverse influence for the stress that promotes steel strand and intermediate plate, bury thus potential safety hazard.
The utility model content
The purpose of this utility model is exactly to design a kind of simple in structure, good stability, be suitable for wide-angle and swing the fluid pressure type of " two hinged " form of structure of moving lifting operation and stride the cable loop wheel machine, the problem that exists to solve the above-mentioned background technology.
The technical solution of the utility model is: a kind of wide-angle swing move lifting stride the cable loop wheel machine, comprise walking structure, main beam structure, lifting jack and lifting steel strand, described walking structure is arranged on the main push-towing rope of suspension bridge, main beam structure and walking structure are articulated and connected by bearing pin, promote steel strand and penetrate lifting jack and be raised the jack clamping, its special character is: described lifting jack and main beam structure are articulated and connected.
Further, described lifting jack and main beam structure are articulated and connected by bearing pin.
The utility model is designed strides the cable loop wheel machine, and main beam structure is articulated and connected by bearing pin and walking structure, and it is the same to stride the cable loop wheel machine with tradition, possesses the ability of rotating between main beam structure and walking structure; Also be articulated and connected by bearing pin between lifting jack and main beam structure, so that also possess turning power between lifting jack and main beam structure, tradition being striden the drawback of " fixed between lifting jack and main beam structure; as to form knuckle easily between main beam structure and lifting steel strand; it is stressed to be unfavorable for promoting steel strand " of cable loop wheel machine improves, be specially: stride the cable loop wheel machine and move past in the journey swinging, the rotation of certain angle can occur between main beam structure and the walking structure, the rotation of certain angle also can occur between lifting jack and the main beam structure, thereby make the lifting steel strand reach the best stressed effect that is in all the time linear state, guarantee that lifting operation carries out safely.
The utility model is simple in structure, convenient and practical, can reduce because swinging and move the temporory structure that lifting is increased input, and shortens the engineering time, and has guaranteed that steel case beam swings the safety of moving lifting operation and carries out smoothly.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not consist of restriction to the utility model.
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of wide-angle swing move lifting stride the cable loop wheel machine, comprise walking structure 1, main beam structure 2, lifting jack 3 and promote steel strand 4, walking structure 1 is fixedly installed on the main rope of suspension bridge 7, main beam structure 2 is articulated and connected with walking structure 1 by the first bearing pin 5, forms and strides cable loop wheel machine load steel structure main body; Lifting jack 3 is articulated and connected with main beam structure 2 by the second bearing pin 6, promotes in the steel strand 4 to penetrate lifting jack 3 and be raised jack 3 clampings, forms and strides cable loop wheel machine Hoisting System.
Such as Fig. 4, shown in Figure 5, striding after the cable loop wheel machine is located on the main rope of suspension bridge 7 in the present embodiment, vertical lifting steel case beam 8 lifts to certain altitude, by horizontal external steel case beam 8 is produced and moves horizontally, and moves to the installation site until steel case beam 8 swung.Swing and move past in the journey, stride the rotation that certain angle occurs between the main beam structure 2 of cable loop wheel machine and the walking structure 1, the rotation of certain angle also occurs between lifting jack 3 and the main beam structure 2, thereby make lifting steel strand 4 be in all the time linear state, reach best stressed effect, guarantee that lifting operation carries out safely.
The utility model is simple in structure, convenient and practical, by the hinged design of lifting jack and girder mechanism, makes to promote steel strand and reach the best stressed effect that is in all the time linear state in the journey swinging to move past, and guarantees that lifting operation carries out safely.
