Abstract
The utility model relates to a bridge crane which overcomes the defects of non-uniform force, unstable running and big noise caused by that rails for supporting large wheels of the bridge crane are not straight, and the bridge crane can reduce self weight as much as possible. The utility model provides a bridge crane, wherein, the main beam of the bridge framework of the bridge crane is a section with small twisting rigidity and in a shape like the Chinese character 'wang'; one balance beam is arranged at one side of the carriage for overcoming the insufficiency that four supporting points are not at the same flat surface because of small twisting rigidity of the framework. The structure has the advantage of small self weight coefficient; compared with the general bridge crane with a box-shaped structure, the weight of the utility model is reduced by about one third. The utility model is easy to manufacture because of exposed welded seams.
Description
The utility model relates to a kind of crane in bridge type.
When design and manufacturing crane in bridge type, wish that all the long rails of supporting crane wheel and the cross track of supporting carriage keep straight.Crane in bridge type is operated steadily, and stressed even, noise is little.In fact, because the sinking of rail support and distortion in use itself will guarantee the straight very difficult of long rails; Cross track straight can guarantee with the rigidity that strengthens the bridge-type framework.
The patent No. is that 4226332 US Patent has disclosed a kind of bridge-type box frame hoisting crane, and it is to put forward for overcoming the not straight shortcoming of track.It is characterized in that: in bridge-type framework end carriage one side one equalizer is installed: the two ends by an adjustable connecting-rod connect a vertical rocking lever separately, it with the end carriage of framework seat on the crank throw neck of bent axle.The inboard seat of the relative crank throw neck of the crank journal of bent axle is on the cart wheel shaft.Like this, can make two groups of big wheels of equalizer one side stressed evenly, constitute three point support with two groups of big wheels of opposite side, thereby overcome because the not straight influence that produces of long rails; The not straight problem of cross track is to solve with the method that improves box frame rigidity.Though this solution has reached purpose; But weak point is: owing to increased the rigidity of bridge-type framework, to the problem that hoisting crane has brought ratio of light weight to loading capacity to increase, size increasing, cost are increased.
The purpose of this utility model is to overcome the deficiency of technique scheme and proposes a solution, satisfy stressed evenly, driving steadily, under the little condition of noise, make it in light weight, cost is low.
The purpose of this utility model can reach by following measure:
The bridge-type framework that this crane in bridge type is become with two girder assembly weldings by two end carriages, the big wheel of supporting bridge-type framework, high-wheeled actuating device, dolly and the elevator that is contained on the dolly constitute.Be characterized in: the girder of bridge-type framework is to become " king " font section beam with steel plate at " I " word steel top flange assembly welding; Have in the middle of one in dolly one side hinged with dolly, the equalizer that two ends link to each other with wheel on being suspended on " I " word steel edge of a wing.
The utility model also can girder vertically on, every a segment distance at " I " figure space of " king " font first half brace panel of burn-oning symmetrically.
Can also between two girders of bridge-type framework, burn-on pull bar to increase its horizontal rigidity every a segment distance.
The bridge-type framework of this structure by means of the deficiency of anti-twist rigidity, allows whole framework torsional deflection to overcome owing to the not straight unbalance stress that is caused of the high-wheeled track of supporting under the condition that guarantees vertical and horizontal rigidity, reaches and operates steadily; By the equalizer effect on the dolly, overcome since the torsional deflection of bridge-type framework so that the shortcoming of four groups of unbalance stress that wheel is not in one plane caused of dolly.
Drawing is described as follows:
Fig. 1 is the utility model crane in bridge type general illustration.
Fig. 2 is the drawing in side sectional elevation of girder.
Fig. 3 is the structural representation of the utility model OTC's trolley.
Embodiment is described in detail the utility model below by (accompanying drawing).
Overhead traveling crane machine frame 1 among Fig. 1 is formed by two end carriages 2 and two girder 3 assembly weldings.Between two girders 3, weld a "T"-shaped pull bar 4 every a segment distance, respectively there is a big wheel 6 of walking in orbit at the two ends of each end carriage 2, in two big wheels 6 on each end carriage 2, there is one to link to each other with actuating device 5, dolly 7 is suspended on the lower flange of girder 3, and elevator 8 is contained on the dolly 7.Girder 3 is to become " king " font section beam (as shown in Figure 2) by " I " word steel 9 and steel plate 10,11 assembly weldings in the above; Girder 3 vertically on, between " I " word steel upper flange and plate 10,11, weld the brace panel 12 of a symmetry every a segment distance; One side of dolly 7 is suspended on by two groups of rollers 15 on the lower flange of a girder (as shown in Figure 3), and opposite side links to each other with the interstitial hole of equalizer 14 by pin 13, and two stomidiums of its equalizer 14 link to each other with the roller 15 that is suspended on another girder lower wing plate.
Advantage of the present utility model is as follows:
1. in light weight, deadweight is little, is 2~2.5, and the ratio of light weight to loading capacity of general bridge-type box frame crane is 3~3.5.
Simple in structure, cost is low.
3. technology is simple, and is easy to manufacture, because compare with box girder, its whole weld seams expose.
Claims (3)
1, a kind of crane in bridge type, comprise the bridge-type framework 1 that two end carriages 2 become with two girder 3 assembly weldings, the big wheel 6 of bearer frame, high-wheeled actuating device 5, the dolly 7 of elevator 8 is housed, it is characterized in that: girder 3 is that " I " word steel 9 and the steel plate that is welded in its top flange 10,11 constitute, and its transversal surface is " king " font.
2, according to the described crane in bridge type of claim 1., it is characterized in that: girder 3 vertically on, be provided with the brace panel 12 of symmetry at " I " figure space of " king " font first half.
3, according to claim 1. or 2. described crane in bridge type, it is characterized in that: between two girders of bridge-type framework, be provided with pull bar 4.
