In view of this, the utility model provides a parallel independent operation's two dolly hoist through setting up the components of a whole that can function independently of major-minor dolly, has shortened the width of hoist greatly.
For solving the above technical problem, the technical scheme of the utility model is that: a parallel and independent running double-trolley crane comprises a main beam and an auxiliary beam which are arranged in parallel; the main beam and the auxiliary beam are respectively provided with a main beam for the main trolley to slide; the main trolley can move back and forth along two main rails; the auxiliary beam is also provided with an auxiliary rail for the auxiliary trolley to slide; the auxiliary rail is arranged on the top surface of the auxiliary beam, two groups of horizontal rollers are arranged on the auxiliary trolley, one group of rollers slides in a matched manner with the inner side surface of the auxiliary rail, and the other group of rollers slides in a matched manner with the outer side plate of the auxiliary beam.
As an improvement, the main trolley comprises a trolley body, wherein a winch, a steel rope wound on the winch and a main hook are arranged on the trolley body.
As an improvement, the plane of the main hook is parallel to the main beam.
Preferably, the auxiliary trolley comprises a trolley body, wherein a winch, a steel rope wound on the winch and an auxiliary hook are arranged on the trolley body.
As an improvement, the plane of the secondary hook is perpendicular to the secondary beam.
Preferably, the primary rail of the secondary beam is arranged at the inner edge of the top surface of the secondary beam, and the secondary rail is arranged at the outer edge of the top surface of the secondary beam. The space between the main rail and the auxiliary rail is enlarged as much as possible, and the auxiliary trolley is convenient to arrange.
As an improvement, the top plate and the inner side plate bracket of the secondary beam are provided with reinforcing plates. The top plate can extend outwards, the main rail is installed towards the edge as much as possible, and the distance between the main rail and the auxiliary rail is enlarged.
The utility model discloses an useful part lies in: the crane with the structure has the advantages that the main trolley and the auxiliary trolley are respectively arranged, the auxiliary trolley adopts a single-track angular arrangement mode, the running width required by the whole crane is greatly reduced, the requirement of the site is reduced on the premise that the crane can still overturn and lift articles, and the applicability is improved.

The labels in the figure are: the main trolley 1, the auxiliary trolley 2, the main rail 3, the auxiliary rail 4, the main beam 5, the auxiliary beam 6, the main hook 11, the auxiliary hook 21 and the idler wheel 22.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.
As shown in fig. 1 and 2, the utility model comprises a main beam 5 and a secondary beam 6 which are arranged in parallel; the main beam 5 and the auxiliary beam 6 are respectively provided with a main beam 3 for the main trolley 1 to slide; the main trolley 1 can collapse two main rails 3 to move back and forth; the auxiliary beam 6 is also provided with an auxiliary rail 4 for the auxiliary trolley 2 to slide; the auxiliary rail 4 is arranged on the top surface of the auxiliary beam 6, two groups of horizontal rollers 22 are arranged on the auxiliary trolley 2, one group of rollers 22 slides in a matched manner with the inner side surface of the auxiliary rail 4, and the other group of rollers 22 slides in a matched manner with the outer side plate of the auxiliary beam 6.
The main rail 3 on the secondary beam 6 is arranged on the top surface of the secondary beam 6 close to the inner side edge, and the secondary rail 4 is arranged on the top surface of the secondary beam 6 close to the outer side edge. Reinforcing plates are arranged on the top plate and the inner side plate bracket of the auxiliary beam 6.
The main trolley 1 comprises a trolley body, wherein a winch, a steel rope wound on the winch and a main hook 11 are arranged on the trolley body. The plane of the main hook 11 is parallel to the main beam 5. Two motors are arranged on the main trolley 1, one motor drives the main trolley to move, and the other motor drives the winch.
The auxiliary trolley 2 comprises a trolley body, wherein a winch, a steel rope wound on the winch and an auxiliary hook 22 are arranged on the trolley body. The plane in which the secondary hooks 22 lie is perpendicular to the secondary beam 6. Two motors are arranged on the auxiliary trolley 2, one motor drives the auxiliary trolley to move, and the other motor drives the winch.
In the utility model, the main trolley 1 adopts the traditional double-track running trolley, and because the auxiliary trolley 2 is not arranged, the width of the main trolley 1 is greatly narrowed, and the left and right limits of the independent running of the main trolley 1 are ensured; the auxiliary trolley 2 adopts a single-rail angular independent trolley running mechanism and is placed on the auxiliary beam 6 to run, so that the main trolley 3 and the auxiliary trolley 3 form an arrangement structure which is parallel and vertical to the main beam 5, and the left and right running limits of the auxiliary trolley 3 are also ensured.
