Description
Technical field
The utility model relates to a kind of cable crane, and the main bearing rope that relates in particular to a kind of cable crane is transferred rope mechanism.
Background technology
The cable crane construction technology is a kind of very common construction technology of bridge construction.It is mainly used in all kinds of Arch Bridge Construction, can be used as the auxiliary all kinds of bridge constructions of a kind of special Transport Machinery simultaneously again.When the bridge design span constantly increased, no support cable crane construction technology was also at synchronized development.Under the constant situation of its basic principle, construction equipment is also being brought in constant renewal in and is being strengthened, and makes this technology be used to construct more convenient, quick, safety and economy.
As shown in Figure 1, the work basic principle of cable crane is: setting up pylon in the two sides of bridge and be used to support various ropes, mainly is main bearing rope, drag cable and hoisting rope.One to two sport car is set on the main bearing rope, below sport car, arranges the lifting tackle pulley, drag cable is installed on the sport car; After drag cable was moved sport car to suitable position, the hook that hoisting rope will lift by crane tackle pulley put down, and hung to be led and was hanging thing; Hoisting rope will be led to be hung thing and slings, and accomplishes hoisting process.Wherein, main bearing rope bears hoisting prefabricated member sections weight in Lift-on/Lift-off System.Bridle sling is around in the lifting tackle pulley of the sport car second line of a couplet, does the usefulness of lift heavy thing.The effect of drag cable is sport car to be drawn to be led hang object location or design and installation position, and drag cable generally adopts single line circulation traction.
Tower top is provided with the saddle of cat head, as the strong point of various ropes on pylon.Two sides also are provided with the main bearing rope anchor device.
Main bearing rope also will be finely tuned after installing.Traditional control method is; Anchorage point (the two pylons outside) at main bearing rope is established a fixing turning point; Main bearing rope one end extends to turning point from two pylon inboards, turns back around turning point again, and a main bearing rope and its end are through transferring rope device (being commonly called as Eight Diagrams head in the industry) fixing.During fine setting, must unclamp the position that the regulating part of transferring in the rope device is adjusted main bearing rope one end.Because main bearing rope has certain weight, the tractive main bearing rope needs very big strength, needs extra use pulling apparatus, and this regulative mode operation is trouble very, and it is inaccurate to regulate the location.Therefore say that from structure turning point and regulating part all play the effect of anchoring, to the structure of regulating part, and strength and stiffness have certain requirement.
The utility model content
To the technical problem that exists in the prior art, the purpose of the utility model is: provide the main bearing rope of cable crane a kind of simple in structure, easy to adjust to transfer rope mechanism.
In order to achieve the above object, the utility model adopts following technical scheme:
The main bearing rope of cable crane is transferred rope mechanism, joins with the plurality of parallel setting and the main bearing rope of arranging of embarking on journey, and comprises fixed part and adjustabel part, and main bearing rope is fixed on the adjustabel part, is provided with the adjusting device of adjusting both distances between adjustabel part and fixed part.
After adopting this structure, only need to regulate adjusting device, can change the distance between fixed part and the adjustabel part, when adjustabel part during away from fixed part, main bearing rope is just loosened; When adjustabel part during near fixed part, main bearing rope just is tightened up.Can finely tune main bearing rope thus.
As a kind of preferred, adjusting device is a twisted steel; After twisted steel one end passes fixed part, fix, after the other end passes adjustabel part, fix by second screw element by first screw element.
This structure is very simple, as long as the turn screw element, i.e. and the relative position of scalable screw element and twisted steel, thus the distance of fixed part and adjustabel part is done an adjustment, and then main bearing rope is adjusted.Need not apply very big power during adjusting, more not need extra use pulling apparatus.
As a kind of preferred, fixed part is the anchor beam along main bearing rope orientation horizontally set.Simple in structure, economical with materials.
As a kind of preferred, adjustabel part is made up of the number overload beam identical with main bearing rope; Every main bearing rope is fixed in the middle of the overload beam corresponding with it, on the both sides symmetric position that on the overload beam with the main bearing rope is the center, respectively connects a twisted steel.After adopting this structure, every main bearing rope can independently be regulated according to the situation of self, regulates more convenient.The twisted steel symmetric arrangement makes stressed more even.
As a kind of preferred, main bearing rope passes the overload beam, and the end connects an anchor head, and anchor head is close to the overload beam.Simple in structure, save the space, can do reliable fixation to main bearing rope.
As a kind of preferred, the length direction of overload beam in perpendicular perpendicular to the axis of main bearing rope here; Two twisted steels are positioned at overload beam both sides up and down.Compact conformation because symmetric arrangement up and down, stressed evenly.
As a kind of preferred, overload beam cross section is the dual-trench type that two channel-section steels are formed.Save material, compact conformation.
As a kind of preferred, first screw element and second screw element are nut; Be provided with pad between first screw element and the anchor beam and between second screw element and the overload beam.Simple in structure, adjusted is convenient.
As a kind of preferred, the main bearing rope equidistance is provided with, and transships the also equidistance setting of beam and adjusting device accordingly.
As a kind of preferred, the horizontal two ends of anchor beam are provided with connecting rod and are convenient to be fixed and are connected in miscellaneous part.
Generally speaking, the utility model has following advantage with respect to prior art: but labour-saving simple in structure regulate, easy to adjust, adjusting position is accurate.

The specific embodiment
To combine the accompanying drawing and the specific embodiment to come the utility model is done further detailed explanation below.
Fig. 2 transfers rope mechanism to be installed between saddle and the main bearing rope anchor device to the main bearing rope of cable crane shown in Figure 4, is used to regulate main bearing rope.It mainly is made up of anchor beam, overload beam, twisted steel and nut.Wherein anchor beam is a horizontally set, specifically, is along the horizontal orientation setting of main bearing rope.The overload beam is the dual-trench type that vertical two channel-section steels that are provided with are formed., the quantity of its quantity and main bearing rope is identical.After twisted steel one end passes anchor beam, screwed by nut, the other end is screwed by nut after passing the overload beam.Be provided with pad between nut and anchor beam, also be provided with pad between nut and overload beam.The end of main bearing rope is fixed in the middle of the overload beam through anchor head, on the overload beam of symmetric position, respectively is provided with a twisted steel about each anchor head.The both lateral sides of anchor beam respectively is provided with a connecting rod, and anchor beam installs and fixes through connecting rod.The equidistance setting arranged side by side of each main bearing rope, corresponding, twisted steel and the also equidistance setting of overload beam.
During adjusting, only need the turn nut, change the relative position of nut and twisted steel, can limit the distance between anchor beam and the overload beam, thus the degree of tightness of regulating main bearing rope.Distance between anchor beam and overload beam strengthens, and it is loosening that main bearing rope becomes; Distance between anchor beam and overload beam reduces, and main bearing rope is tightened up.
