Problems solved by technology

When this kind of crane is working, especially when the trolley moves along the trolley track on the box girder, the noise is particularly loud, which can sometimes affect the production operation of workers. One of the reasons is that the box girder is a hollow structure, which acts as a resonance cavity On the other hand, the outer surface of the box girder is processed with ribs, and the concave gaps are formed on both sides of the ribs, which increases the surface area and contributes to the transmission of noise. At present, no traffic with low operating noise has been seen, and there is no information , media records and reports

Embodiment Construction

[0008] figure 1 The medium and low-noise trains include a box girder 1, wheels are installed at both ends of the box girder 1, ribs 3 and trolley tracks are installed on the outer surface of the box girder 1, and movable The trolley is equipped with an electric hoist, and the inner space of the box girder 1 and the recessed space 4 on both sides of the rib plate 3 are filled with polyurethane foam material 2 (the wheel set, trolley track, trolley, electric Gourds are not shown). The polyurethane foam material 2 in the inner space of the box girder 1 destroys the resonant cavity structure in the inner space of the box girder 1, and the polyurethane foam material 2 in the recessed spaces 4 on both sides of the rib plate 3 changes the noise from The propagation medium that the box girder spreads to the surrounding space, and the polyurethane foam material has the characteristics of flexibility and microporosity, and has a certain sound absorption effect, so it can be transmitted...

Abstract

The invention relates to hoisting mechanical devices, and particularly relates to the improvement of traveling cranes. The low-noise traveling crane comprises a box-type beam, wherein two ends of the box-type beam are provided with wheel groups; the outer surface of the box-type beam is provided with rib plates and trolley tracks; the trolley tracks are provided with a movable trolley; the trolley is provided with an electric hoist; the internal spaces of the box-type beam and concave clearances in two sides of the rib plates are internally filled with polyester foaming materials. The low-noise traveling crane has the advantages of low running noise, environment protection and slight interference to workers.

Description

Technical field: [0001] The present invention relates to a hoisting mechanism, in particular to the improvement of driving. Background technique: [0002] The crane is widely used in factories, construction sites, ports, docks, freight transfer hubs and other places because of its convenient use and high work efficiency. This kind of crane does not need to occupy the floor of the workshop, and can easily lift various parts and devices. Almost all workshops that need large-scale hoisting are equipped with cranes. The current driving is mainly composed of a box girder (also known as a bridge frame, a rectangular frame), a trolley track installed on the box girder, and a trolley that can move along the trolley track. Wheel sets are installed at both ends of the box girder. The cart can move along the cart track on the column, and the electric hoist is installed on the trolley to lift objects. When this kind of crane is working, especially when the trolley moves along the trol...
