Technical field
The present invention relates to a kind of crane anti-swing system, particularly relate to a kind of crane anti-swing system adopting X-type truss.
Background technology
For the ease of operating and raising the efficiency, the suspender of hoisting crane is provided with anti-sway system mostly.The crane anti-swing system of prior art comprises six kinds: (1) rigidity guide braking anti-sway system: install guide above suspender, guide rolls or slides and is elevated in the urceolus be connected with trolley frame, framework, utilize the rigidity of guide and dolly, resist horizontal force suffered by suspender, thus effectively prevent rocking of suspender and load; (2) be separated car-type anti-sway system: by front and back travelling jack is separated a segment distance, make hanging steel rope form del, the component producing horizontal direction reaches anti-object of shaking; (3) hydraulic anti-sway system: utilize hydraulic actuating cylinder to increase system damping, controls existing waving; (4) auxiliary steel wire rope anti-sway system: by arranging one group of cross one another auxiliary steel wire rope between dolly and suspender, by intersecting to form several stable triangular structure, its oblique pulling produced is to having waved inhibit function; (5) inverted triangle eight is restricted anti-sway system: by increasing assembly pulley, what make hoist rope is arranged to del, utilizes the component of raising line horizontal direction to carry out anti-shaking; (6) electronic anti-swinging system: by modern scientist and measurement means, dolly and suspender link, relative distance and the height of dolly and target location is measured by detecting device, control dolly when slow down and brake, reduce lift heavy drift angle, make it accurately be positioned above target, thus initiatively avoid waving.
In above-mentioned several crane anti-swing system, rigidity guide brake type complex structure, cost is higher, is mainly applicable to the occasion that lifting altitude is lower; Be separated car-type complex structure, maintenance and debugging is cumbersome, and anti-effect of shaking is general; Hydraulic anti-sway system and auxiliary steel wire rope anti-sway system complex structure, cost is high, and maintenance and debugging bothers; The restrict winding of anti-sway system steel rope of inverted triangle eight is complicated, and steel rope abrasion increases, and the life-span declines; Electronic anti-swinging system cost is high, and detail programming difficulty is large, and crab traversing speed adjustment is too frequent, easily causes the discomfort of driver.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of crane anti-swing system adopting X-type truss is provided.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
Adopt the crane anti-swing system of X-type truss, comprise trolley frame 100, multiple hydraulic actuating cylinder 200, X-type truss 300, sling upper rack 400 and lifting pulley 500, wherein:
Multiple hydraulic actuating cylinders 200 are fixed on the two ends of trolley frame 100 symmetrically;
X-type truss 300 comprises the parallel support in both sides and connects the crossbeam of two side stands, the top of two side stands can be connected to multiple hydraulic actuating cylinder 200 respectively and be the X-type carrier unit of multiple repetition with driving, connected by hinge between X-type carrier unit, the parallel carrier unit in both sides is connected by crossbeam;
The bottom of two side stands is fixed to sling upper rack 400;
Lifting pulley 500 is installed on sling upper rack 400.
According to one embodiment of present invention, the intersection point of the X-type carrier unit of two side stands comprises movable hinge and free point, and the hinge between X-type carrier unit is movable hinge.
According to one embodiment of present invention, the number of repetitive is 3.
Advantage of the present invention is: the crane anti-swing system of employing X-type truss of the present invention, owing to make use of X-type truss, improves resistance to overturning, actv. increases rigidity and the damping of lift heavy suspension, safe and reliable, anti-shake effective, the rapid-aligning of suspender can be realized, improve handling efficiency.

Description of reference numerals
100 trolley frames, 200 hydraulic actuating cylinders, 300X type truss, 310X type truss movable hinge, 320X type truss free point, 400 sling upper racks, 500 lifting pulley.
Detailed description of the invention
Fig. 1 and Fig. 2 shows the schematic diagram of the crane anti-swing system of the employing X-type truss of one embodiment of the present of invention, it comprises trolley frame 100, multiple hydraulic actuating cylinder 200, X-type truss 300, sling upper rack 400 and lifting pulley 500, wherein: multiple hydraulic actuating cylinders 200 are fixed on the two ends of trolley frame 100 symmetrically, X-type truss 300 comprises the parallel support in both sides and connects the crossbeam of two side stands, and the top of two side stands can be connected to multiple hydraulic actuating cylinder 200 respectively and be the X-type carrier unit of multiple repetition with driving, the bottom of two side stands is fixed to sling upper rack 400, lifting pulley 500 is installed on sling upper rack 400, the intersection point of the X-type carrier unit of two side stands comprises movable hinge 310 and free point 320, the intersection point of the X-type carrier unit that distance sling upper rack 400 is nearest is free point 320, this free point 320 ensures that truss can Free Transform, hinge between multiple X-type carrier unit is movable hinge 310, movable hinge 310 can ensure the stability of truss when static state, the parallel carrier unit in both sides is connected by crossbeam, triangular structure is defined between movable hinge 310, can freely rotate during motion, both the stability of structure had been maintained, achieve again the dilatation effect of whole truss.
Fig. 3 shows the X-type carrier unit of the employing X-type truss of an embodiment, and in a preferred embodiment, the number of X-type carrier unit is 3.
The crane anti-swing system of employing X-type truss of the present invention operationally, controls the distortion of X-type truss 300 by the hydraulic actuating cylinder 200 be fixed on trolley frame 100.When beat does not occur lift heavy (not shown), the pressure-modulation valve of hydraulic actuating cylinder 200 is opened, and ensures that X-type truss 300 can with hoisting and down maneuver Free Transform; When the acceleration and deceleration of lifting trolley (not shown), will there is beat in lift heavy, while dolly accelerates or brakes, the pressure-modulation valve of hydraulic actuating cylinder 200 is closed, make X-type truss 300 keep solid shape, increase rigidity and the damping of suspension, thus effectively suppress waving of lift heavy.The horizontal force that lift heavy waves mainly born by X-type truss, and hoisting of lift heavy is still born by hoist rope, therefore truss structure can do relatively simple, and lighter weight.
While specific embodiments of the invention are described in detail, the embodiment that can also find plurality of replaceable design similar in this area related to the present invention and be defined by the claims.
