Abstract
The invention provides a circular track cantilever crane. The circular track cantilever crane comprises a pair of operation cars, and a first circular track used for hanging the pair of operation cars, wherein the pair of operation cars comprises two main bodies, and driving mechanisms for driving pairs of operation pulleys to move; at least one pair of operation pulleys fitting the first circular track are arranged on each of the main bodies; the bottoms of the two main bodies are both connected with a cantilever beam through hinge shafts; a slide chain block operated along the cantilever beam is arranged on the cantilever beam; the two main bodies are connected through a connecting beam; an included angle matched with a radian of the first circular track is formed between the two main bodies; and the circular track cantilever crane further comprises an overturn preventing mechanism. The circular track cantilever crane expands a linear lifting range to a circular lifting range, so that the crane operation range is widened, the operation position adjusting range is provided, and the service efficiency is improved.
Description
Technical field
The present invention relates to a kind of circular orbit cantilever derrick.
Background technology
The track of existing cantilever derrick is linear pattern, and therefore scope of work is only limitted in the linearity region at track two ends, and therefore lifting scope is less and cannot adjust position, especially cannot carry out operation in the region perpendicular to this two end point connecting line direction.
Summary of the invention
The technical problem to be solved in the present invention is the less defect of the lifting and range of operation in order to overcome hoisting crane in prior art, provides a kind of circular orbit cantilever derrick.
The present invention solves above-mentioned technical matters by following technical proposals:
A kind of circular orbit cantilever derrick, it comprises a pair operation car, and its feature is, this circular orbit cantilever derrick also comprises one first circular orbit, and this first circular orbit is for hanging this to operation car;
This includes a body to operation car, each described body is equipped with at least one pair of for the operation pulley and that coordinates with this first circular orbit for driving this to the driver train running pulley motion; The bottom of described two bodies is all connected with a cantilever beam by a hinge, and hanging oneself at this cantilever beam is provided with a slot cucurbit run along this cantilever beam; Wherein, connected by a tie-beam between described two bodies, and formed between described two bodies one with the angle of the radian adaptation of this first circular orbit;
This circular orbit cantilever derrick also comprises an overturn-preventing mechanism.
Wherein, this overturn-preventing mechanism comprises one and is positioned at the second circular orbit outside this first circular orbit, and the horizontal surface at this second circular orbit place is lower than the horizontal surface at this first circular orbit place; One end that this cantilever beam points to this second circular orbit is provided with the anti-roller with this second circular orbit adaptation.
Wherein, the rotating shaft of described anti-roller is for being horizontally disposed with; The contact surface of described second circular orbit and this anti-roller points to described body.
Wherein, the rotating shaft of described anti-roller is vertically arrange; The contact surface of described second circular orbit and this anti-roller points to ground.
Wherein, the cross-sectional plane of the second described circular orbit is in " C " font.
In the present invention, above-mentioned optimum condition can combination in any on the basis meeting this area general knowledge, obtains each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: linear lifting scope is extended to the lifting scope of an annular by circular orbit cantilever derrick of the present invention, the range of operation not only adding hoisting crane provides the scope of run location adjustment, improves service efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the circular orbit cantilever derrick in a preferred embodiment of the present invention.
Fig. 2 is the lateral plan of the circular orbit cantilever derrick in Fig. 1.
Fig. 3 is the structural representation running car for a pair in Fig. 1.
Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.
Embodiment 1
As shown in Fig. 1 ~ 2, the circular orbit cantilever derrick in the present embodiment comprises first circular orbit 1, hangs establish a pair operation car 3 in the below of this first circular orbit 1.
As shown in Figure 3, this comprises two bodies 32 to operation car 3, each body 32 is equipped with two to the operation pulley 31 for coordinating with this first circular orbit 1; And for driving this to the motor 34 running pulley 31 motion; The bottom of two bodies 32 is all connected with a cantilever beam 5 (see Fig. 1 and 2) by a hinge, and this cantilever beam 5 is provided with a slot cucurbit 6 (see Fig. 2) run along this cantilever beam 5.Wherein, tie-beam 33 by a rigidity between two bodies 32 connects, and formed between described two bodies 32 one with the angle of the radian adaptation of this first circular orbit 1, thus make this can remain that in operational process the bearing of trend along the first arc track moves to operation car.
Owing to needing to lift weight on the cantilever beam 5 extended along the radial direction of the first arc track 1, therefore this circular orbit cantilever derrick is also provided with an overturn-preventing mechanism.
Again as illustrated in fig. 1 and 2, the overturn-preventing mechanism in the present embodiment comprises one and is positioned at the second circular orbit 2 outside the first circular orbit 1, and the horizontal surface at this second circular orbit 2 place is lower than the horizontal surface at this first circular orbit 1 place.The one end pointing to this second circular orbit 2 at cantilever beam 5 is provided with the anti-roller 4 with this second circular orbit 2 adaptation.
Further, the cross-sectional plane of the second circular orbit 2 in the present embodiment is in " C " font, and therefore the inwall of the second circular orbit 2 provides an antagonistic force, prevents the operation car of hoisting crane to topple phenomenon.The remainder of this operation car is same as the prior art, does not repeat them here.
Embodiment 2
The difference of the present embodiment and embodiment 1 is, in the present embodiment, the rotating shaft of this anti-roller is in vertically arranging, and the C type opening of this second circular orbit points to ground.Remainder is identical with embodiment 1, does not repeat them here.
