The cantilever crane comprises a pair of operation vehicles, a first circular railway for hanging the pair of operation vehicles, and a driving mechanism for driving a plurality of pairs of operation pulleys to move, wherein the pair of operation vehicles comprises two bodies; each body is provided with at least one pair of operation pulleys matched with the first circular railway; the bottoms of the two bodies are both connected with a cantilever beam through hinge shafts; a sliding chain block is arranged on the cantilever beam and can move along the cantilever beam; the two bodies are connected through a connection beam; an included angle matched with the radian of the first circular railway is formed between the two bodies. The cantilever crane further comprises an overturn preventing mechanism. According to the cantilever crane, a linear lifting range is expanded to a circular lifting range, so that the operation range of the cantilever crane is increased, the operation position regulating range of the cantilever crane is provided, and the service efficiency is improved.
Description
Technical field
The utility model relates to a kind of circular orbit cantilever derrick.
Background technology
The track of existing cantilever derrick is linear pattern, so scope of work only limits in the linearity region at track two ends, so lifting scope is less and cannot adjust position, especially cannot carry out operation perpendicular to the region of this two-end-point line direction.
Utility model content
The technical problems to be solved in the utility model is in order to overcome lifting and the less defect of range of operation of hoisting crane in prior art, a kind of circular orbit cantilever derrick to be provided.
The utility model is to solve above-mentioned technical matters by following technical proposals:
A cantilever derrick, it comprises a pair of operation car, and its feature is, and this circular orbit cantilever derrick also comprises one first circular orbit, and this first circular orbit is used for hanging this to operation car;
This includes a body to operation car, described in each, on body, be equipped with at least one pair of for the operation pulley that coordinates with this first circular orbit and for driving this to moving the driver train of pulley motion; The bottom of described two bodies is all connected with a cantilever beam by a hinge, at this cantilever beam, hangs oneself and is provided with a slot cucurbit along this cantilever beam operation; Wherein, between described two bodies, by a tie-beam, connect, and between described two bodies, form 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 ，Gai overturn-preventing mechanism comprises that one is positioned at second circular orbit in this first circular orbit outside, 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 the second circular orbit and this anti-roller points to described body.
Wherein, the rotating shaft of described anti-roller is vertically to arrange; The contact surface directed towards ground of described the second circular orbit and this anti-roller.
Wherein, the cross-sectional plane of the second described circular orbit is " C " font.
In the utility model, above-mentioned optimum condition can combination in any on the basis that meets this area general knowledge, obtains each preferred embodiment of the utility model.
Positive progressive effect of the present utility model is: circular orbit cantilever derrick of the present utility model is extended to linear lifting scope the lifting scope of one annular, the range of operation that has not only increased hoisting crane provides the scope of run location adjustment, has improved service efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the circular orbit cantilever derrick in the utility model one preferred embodiment.
Fig. 2 is the lateral plan of the circular orbit cantilever derrick in Fig. 1.
Fig. 3 is the structural representation of a pair of operation car in Fig. 1.
The specific embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
Embodiment 1
As shown in Fig. 1～2, the circular orbit cantilever derrick in the present embodiment comprises first circular orbit 1, below this first circular orbit 1, hangs and establishes a pair of operation car 3.
As shown in Figure 3, this comprises two bodies 32 to operation car 3, is equipped with two pairs of operation pulleys 31 for coordinating with this first circular orbit 1 on each body 32; And for driving this motor 34 to 31 motions of operation pulley; The bottom of two bodies 32 is all connected with a cantilever beam 5 (seeing Fig. 1 and 2) by a hinge, is provided with a slot cucurbit 6 (seeing Fig. 2) along these cantilever beam 5 operations on this cantilever beam 5.Wherein, tie-beam 33 by a rigidity between two bodies 32 connects, and between described two bodies 32, form one with the angle of the radian adaptation of this first circular orbit 1, thereby make this that operation car can be remained along the bearing of trend of the first arc track and be moved in operational process.
Owing to needing to lift weight on the cantilever beam 5 radially extending along the first arc track 1, so 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 that one is positioned at second circular orbit 2 in the first circular orbit 1 outside, and the horizontal surface at these the second circular orbit 2 places is lower than the horizontal surface at this first circular orbit 1 place.One end of pointing to this second circular orbit 2 at cantilever beam 5 is provided with the anti-roller 4 with these the second circular orbit 2 adaptations.
Therefore and the cross-sectional plane of the second circular orbit 2 in the present embodiment is " C " font, the inwall of the second circular orbit 2 provides an antagonistic force, the operation car that the prevents hoisting crane phenomenon of toppling.The remainder of this operation car is same as the prior art, does not repeat them here.
The difference of the present embodiment and embodiment 1 is, in the present embodiment, the rotating shaft of this anti-roller is vertical setting, the C type opening directed towards ground of this second circular orbit.Remainder is identical with embodiment 1, does not repeat them here.
