Abstract
The utility model discloses a mechanical device, in particular to a bridge crane. The end beam device comprises end beams and a girder, wherein one side of the bridge crane at least comprises two sections of end beams, a pin shaft and a connecting beam; and the end beams are connected through the pin shaft and the connecting beam to form an articulated multi-section end beam device. The end beam device has the advantages of convenience of processing and installation as well as lower deadweight, is easier for installation relative to the traditional design, and reduces the working intensity and time of workers. The end beam device can be widely used for ports, docks and other places.
Description
Technical field
The utility model relates to a kind of mechanical equipment, refers in particular to a kind of crane in bridge type.
Technical background
In the last few years, along with the development of hoisting crane industry, the demand of bridge machine was increasing, hoisting capacity G
n, lifting altitude H and span L require increasingly, from tens to nearly kiloton, span and lifting altitude be from tens to hundred meters leap all.Bridge machine lifting altitude H increases, trolley span l
2Strengthen, directly have influence on the increase of end carriage and girder corresponding size.The drawback that the traditional design mode of bridge machine end carriage device such as figure two more and more embody it:
The first, end carriage length is long, and deadweight increases, and is higher to the requirement of Fabricating machinery, has increased the cost of equipment greatly; It is big that end carriage length becomes, and the same potential difference such as the figure three of wheel are also wayward;
The second, bridge machine span L hour, traditional end carriage device and two girders are connected to form crane span structure, girder and two butt beams connect to form crane span structure, girder is connected as 1 point with end carriage, that just is equivalent to 4 fixed one sides, look like figure one, two for 4 fixed one, quality and the labour intensity to the manufacturing operator requires high like this.First, second point is in case satisfied, and the bridge machine just causes cart wheel unbalance stress, gnaws problems such as rail and wearing and tearing when moving.
The utility model content
This practicality has proposed a kind of new design plan at the deficiency in the traditional end carriage device design that occurs, and actv. has solved the problem of above-mentioned existence.
The utility model is achieved by following technical proposals:
The end girders of overhead traveling crane device, it comprises: end carriage, girder is characterized in that: crane in bridge type one side has at least two sections end carriages, bearing pin, tie-beam to form; Tie-beam couples together the multistage end carriage by bearing pin, has formed the multistage end carriage device of radial type.
As preferably, the end carriage of crane in bridge type one side described in the above-mentioned end girders of overhead traveling crane device is formed by two sections.
As other parts of crane in bridge type, keep similar structure in the prior art.
Beneficial effect:
Easy to process, weight reduction.Lifting altitude H increases, the length that traditional design need strengthen end carriage meets the demands, and extend the basically length of tie-beam of new design just can solve, require lower to the end carriage Fabricating machinery like this, the wheel of end carriage is also easy to control with potential difference, and normalisation, the modularization for end carriage provides convenience simultaneously; Under the bridge machine hoisting capacity situation identical with deadweight, the section modulus of this end carriage also can reduce half, and new according to statistics design can be than the weight reduction of traditional design about 40%;
Easy for installation.New design is being installed, and is connected respectively with two girders by two butt beams, finally connects to form crane span structure by bearing pin, saves the installation of high strength bolt group, can eliminate a part of cart wheel gnawing rail, worn-down influence by the adjusting of bearing pin self simultaneously.Install easily with respect to traditional design, reduced working strength of workers and time.

The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is specified.
Embodiment 1
Crane in bridge type as structure among accompanying drawing 1, Fig. 2, Fig. 3 comprises dolly 1, girder 2, traveling mechanism of the larger traveller 3, end carriage device 4; End carriage device 4 wherein comprises end carriage 5, bearing pin 6, tie-beam 7 and girder 8.Wherein a side of crane in bridge type is to be made up of two sections end carriages 5, bearing pin 6, tie-beam 7; Tie-beam 7 couples together two sections end carriages 5 by bearing pin 6, has formed the multistage end carriage device 4 of radial type, as shown in Figure 4 structure.
In the utility model, through the crane in bridge type of reequip, under the situation of bearing identical lifting intensity, it is about 40% that the deadweight of the end carriage device 4 of hoisting crane can alleviate, and simultaneously, is not prone to phenomenons such as gnawing rail during easy for installation, use.
