Abstract
The utility model relates to the technical field of construction project construction, in particular to a self-propelled type precast beam steel stranded wire lifting jack hoisting frame. The self-propelled type precast beam steel stranded wire lifting jack hoisting frame comprises a support frame, a cross beam arranged at the top of the support frame, a walking device and a hoisting device, wherein the hoisting device is hung on the cross beam at the top of the support frame and is used for hoisting a lifting jack, the walking device is arranged at the bottom of the support frame, and hoisting frame moves by utilizing travelling wheels. The self-propelled type precast beam steel stranded wire lifting jack hoisting frame is simple in structure, scientific in design, and convenient to operate, conveys the lifting jack to the position of a steel stranded wire by means of the movable support frame, and hoists the lifting jack to an appropriate height through the hoisting device. The entire operation can be completed by one to two persons, the work efficiency is high, labor power is effectively saved, and the safety factor in the construction process is improved.
Description
Technical field
The utility model relates to the engineering construction mechanical field, relates in particular to the plant equipment of using in a kind of bridge construction.
Background technology
In most post-tensioned prestressings and pre-tensioned prestressing engineering, steel strand are the prestressing steels that the most extensively adopt.The resistance to tension of steel strand is stronger than general reinforcing bar, therefore is widely used in highway bridge, the railroad bridge construction, and purpose is the resistance to tension that strengthens bridge, thereby the safety that guarantees bridge engineering is firm.
For prefabricated bridge, steel strand need to put in the bridge in prefabricated process by designing requirement, then by jack pair steel strand stress application, thus the anti-pressure ability of raising bridge.In actual mechanical process, the stress of steel strand applies generally to be finished at the construction field (site), owing to being subjected to the limitation of place equipment, jack all is by the stretch-draw position of men hoisting to steel strand, and then stress application stretch-draw is because jack weight is heavier, need several individuals to finish when therefore often operating, especially the beam slab height is high, and steel strand are particularly time-consuming aloft the time, also have potential safety hazard.
Summary of the invention
To be solved in the utility model is exactly at present by the men hoisting jack, wastes time and energy, and also has the problem of potential safety hazard, and a kind of time saving and energy saving, safe and reliable self-propelled precast beam steel strand hoisting jack pulling yoke is provided.
Self-propelled precast beam steel strand hoisting jack pulling yoke of the present utility model, it is characterized in that this hoisting frame comprises crossbeam, running gear and the lifting gear of support, a top of the trellis, lifting gear is suspended on the crossbeam of a top of the trellis, be used for lifting jack, running gear is installed in frame bottom, and hoisting frame utilizes road wheel to move.
Also be provided with pulley on the described crossbeam, lifting gear is connected with pulley, is convenient to adjust the lifting gear position.
Described running gear is four road wheels, is installed in respectively on four pin of frame bottom.
Described lifting gear is hand cucurbit or electrodynamic type cucurbit, comprises hook, lower draw-bar and chain cable, and lifting gear is suspended on the pulley by upper hook, and lower draw-bar is installed in chain cable one end.
Described frame bottom also is provided with supporting plate, is used for placing jack.
In work progress, at first jack is placed on the supporting plate of support, by transporting bracket near steel strand; Then hook jack with lower draw-bar, utilize the electric hoist crane gear to shrink chain cable, jack is lifted to proper height, and then slides by the pulley on the crossbeam, steel strand are penetrated jack inside, utilize jack that steel strand are strained.
Self-propelled precast beam steel strand hoisting jack pulling yoke of the present utility model, simple in structure, design science, easy to operate, the support that utilization can be walked is transported to the steel strand place with jack, by lifting gear jack is risen to suitable height again, only need one to two people can finish whole operation, high efficiency has also effectively been saved manpower, improves the safety factor in the work progress.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model top view.
Fig. 3 is that the utility model uses state diagram.
Wherein, support 1, crossbeam 2, pulley 3, upper hook 4, electrodynamic type cucurbit 5, chain cable 6, lower draw-bar 7, road wheel 8, supporting plate 9, jack 10.
The specific embodiment
Embodiment 1: a kind of self-propelled precast beam steel strand hoisting jack pulling yoke, formed by support 1, four road wheels 8, electrodynamic type cucurbits 5, a crossbeam 2 is fixed at support 1 top, the bottom is placed with a supporting plate 9, arrange on the crossbeam 2 on four pin that 3, four road wheels 8 of pulley are installed in respectively support 1 bottom; Electrodynamic type cucurbit 5 comprises hook 4, lower draw-bar 7 and chain cable 6, and upper hook 4 is hooked on the pulley 3, and lower draw-bar 7 is installed in chain cable 6 one ends, is connected with jack 10.
In work progress, at first jack 10 is placed on the supporting plate 9 of support 1, be transported near the steel strand by support 1; Then hook jack 10 with lower draw-bar 7, utilize the electric hoist crane gear to shrink chain cable 6, jack 10 is lifted to proper height, and then slide by the pulley 3 on the crossbeam 2, steel strand are penetrated jack 10 inside, utilize jack 10 that steel strand are strained.
