A Realization Scheme of Support Mechanism of Wall Travelling Jib Crane

The wall travelling jib crane is a small and medium-sized transportation equipment with unique structure, safety and reliability, high efficiency, energy saving, time-saving, flexible and other characteristics. It can be operated at will in three-dimensional space. It is better than other conventional cranes in the occasion of segmental and dense transportation whcht shows its superiority and it is widely used in different places in various industries.

In the main products of Dejun, BB series wall travelling jib cranes are widely used in the lifting of light, small and heavy objects in industrial and mining, workshops, assembly lines, warehouses, docks and other occasions. It is an energy-saving and efficient material lifting equipment that can be customized according to client needs.

For example, the Chinese patent Z200620127451.2, a wall travelling jib crane described in the specification named "Wall-travelling Jib Crane", includes a frame, a beam, and an electric hoist under the beam. The electric hoist is fixed with the electrical box connected by the external power cord, which also includes an upper bracket and a lower bracket fixed on the wall column, and an upper rail and a lower rail set on the upper and lower brackets.The upper and lower ends of the rack are respectively fixed with a side wheel. The walking wheels of the cross arm and the wheel cross arm are in contact with the upper rail and the lower rail respectively. The driving wheel cross arm is fixed under the frame, and the walking wheel of the driving wheel cross arm is located on the lower rail.

The rails of this wall-travelling jib cranes are connected to the wall of the building through brackets, especially the upper rail is connected to the wall by bolts or similar methods. Under the weight of the beam and the gravity of the lifting object, the walking wheels are set the radial thrust of the upper rail is very large, and the upper rail connection method of the existing wall cantilever crane has hidden dangers, which may easily cause the upper bracket to separate from the wall of the building, so the lifting weight is limited.

The purpose of the scheme introduced in this article is to provide a safe, reliable, and heavy-lifting wall travelling cantilever crane support mechanism. The technical solution to achieve the purpose of the utility model is: a wall travelling jib crane support mechanism with a frame and a beam: the frame is arranged at the left end of the beam, the upper part of the frame is provided with an upper guide rail, and the lower part of the frame is provided with a lower guide rail and walking rail, the upper end of the rack is provided with a set of upper horizontal support wheels, a set of lower horizontal support wheels and a set of walking wheels. The upper horizontal support wheel is located on the left side of the upper rail and it is in rolling contact with the upper rail. The lower horizontal support wheel is located on the right of the lower rail. The side is in rolling contact with the lower rail, and the traveling wheel is located above and in rolling contact with the traveling rail.

The frame of the above-mentioned wall mounted crane is a "well" frame body, with two vertical beams, an upper horizontal wheel beam at the upper end of the vertical beam, a lower horizontal wheel beam at the lower end of the vertical beam, and a traveling wheel at the upper part of the lower horizontal wheel beam The upper horizontal support wheel is arranged on the upper horizontal wheel beam, the lower horizontal support wheel is arranged on the lower horizontal wheel beam, and the traveling wheels are arranged on the traveling wheel beam.

The cross beam of the above wall cantilever crane is a truss structure, the main body is H beam, the connecting bar is angle steel, the cross beam is upturned as a whole, and the horizontal height of the front end of the cross beam is 1035 mm higher than the rear end.

The utility model has the following characteristics:

(1) The utility model adopts the layout of upper and lower guide rails and upper and lower horizontal wheels, which makes the wall cantilever crane safer and more reliable, without the problem of guide rail connection, and effectively increases the lifting weight of the crane.

(2) The beam of the utility model adopts a truss structure, which reduces its own weight, saves steel materials, and achieves the overall purpose of reducing costs and increasing efficiency.
