Abstract
The utility model discloses a kind of double girder crane dolly, comprise trolley platform, dolly crossbeam and be arranged at the dolly end carriage at dolly crossbeam two ends, between dolly end carriage corresponding to one end of described dolly crossbeam and this end, be bolted, between dolly end carriage corresponding to the other end of described dolly crossbeam and this end, connect by flexibly connecting axle; Described flexibly connecting between axle and described dolly crossbeam left gap, and, described in flexibly connect the top of axle higher than the end face of described dolly crossbeam.The utility model can make double girder crane dolly in use, change the height of the single wheel of double girder crane dolly by flexibly connecting the flexible characteristic of axle, and then can realize double girder crane dolly four-wheel and land, prevent that the phenomenon of " three leg " from occurring; In addition, can also there is small free-running fit by flexibly connecting between axle and dolly end carriage in the utility model, realizes in the situation that track installation parallelism error is large, prevents that the phenomenon of gnawing rail from occurring.
Description
Technical field
The utility model relates to hoisting crane technical field, specifically, relates to a kind of double girder crane dolly.
Background technology
At present, type of attachment between crossbeam and the end carriage of double girder crane dolly mainly contains integral solder and bolt is connected, wherein, integral solder refers to trolley platform is welded direct on dolly end carriage, because being is directly directly welded on trolley platform on dolly end carriage, and dolly rigidity is larger, therefore, four wheels of dolly must have setting device to land to ensure four wheels, but " three leg " phenomenon that orbit error causes cannot be improved, easily occur that driving wheel skids, power-handling capability declines.Cause the rail of gnawing that asymmetric driving causes simultaneously.Bolt connects and refers to and by bolt, dolly end carriage top flange plate and dolly cross-beam connecting plate are linked together (the common connection mode of current European hoisting crane), and between two bolts, flexible straight pin is as the use of location.This mode being bolted is with directly welding manner is similar, when there is welding deformation and machining error, cannot ensure that on dolly end carriage, four wheels land simultaneously.
For the problem in correlation technique, actv. solution is not yet proposed at present.
Utility model content
For the problem in correlation technique, the utility model proposes a kind of double girder crane dolly, can avoid " three leg " phenomenon by actv..
The technical solution of the utility model is achieved in that
A kind of double girder crane dolly, comprise trolley platform, dolly crossbeam and be arranged at the dolly end carriage at dolly crossbeam two ends, between dolly end carriage corresponding to one end of described dolly crossbeam and this end, be bolted, between dolly crossbeam corresponding to the other end of described dolly crossbeam and this end, connect by flexibly connecting axle.
Further, described in, flexibly connecting axle is fixed between described dolly crossbeam and described dolly end carriage by locating dowel pin and high-strength tie bolt.
Further, described in flexibly connect between axle and described dolly crossbeam and leave gap, and, described in flexibly connect the top of axle higher than the end face of described dolly crossbeam.
Preferably, the cross-sectional plane that flexibly connects axle described in is T shape structure.
The utility model flexibly connects axle and connects by adopting between the one end at dolly crossbeam and dolly end carriage corresponding to this end, thereby make double girder crane dolly in use, change the height of the single wheel of double girder crane dolly by flexibly connecting the flexible characteristic of axle, and then can realize double girder crane dolly four-wheel and land, prevent that the phenomenon of " three leg " from occurring.
In addition, the utility model also leaves gap by flexibly connecting between axle and dolly end carriage, and make to flexibly connect the top of axle higher than the end face of dolly end carriage, thereby make to flexibly connect between axle and dolly end carriage and have small free-running fit, can there is certain lateral adjustment, and then can realize in the situation that track installation parallelism error is large, prevent that the phenomenon of gnawing rail from occurring.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is according to one of structural representation of the double girder crane dolly of the utility model embodiment;
Fig. 2 is according to two of the structural representation of the double girder crane dolly of the utility model embodiment;
Fig. 3 is the local amplification view at A place in Fig. 2.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope that the utility model is protected.
As Figure 1-3, according to a kind of double girder crane dolly of the utility model embodiment, comprise trolley platform 1, dolly crossbeam 2 and be arranged at the dolly end carriage 3 at dolly crossbeam 2 two ends, between dolly end carriage 3 corresponding to one end of described dolly crossbeam 2 and this end, connect by bolt 4, between dolly crossbeam 3 corresponding to the other end of described dolly crossbeam 2 and this end, connect by flexibly connecting axle 5.
In one embodiment, described in, flexibly connecting axle 5 is fixed between described dolly crossbeam 2 and described dolly end carriage 3 by locating dowel pin 6 and high-strength tie bolt 7.
In one embodiment, described in flexibly connect between axle 5 and described dolly crossbeam 2 and leave gap, and, described in flexibly connect the top of axle 5 higher than the end face of described dolly crossbeam 2.
In the time of practical application, described in flexibly connect axle 5 cross-sectional plane be preferably T shape structure.
The utility model flexibly connects axle 5 and connects by adopting between the one end at dolly crossbeam 2 and dolly end carriage 3 corresponding to this end, thereby make double girder crane dolly in use, change the height of the single wheel of double girder crane dolly by flexibly connecting the flexible characteristic of axle 5, and then can realize double girder crane dolly four-wheel and land, prevent that the phenomenon of " three leg " from occurring.
In addition, the utility model also leaves gap by flexibly connecting between axle 5 and dolly end carriage 2, and make to flexibly connect the top of axle 5 higher than the end face of dolly end carriage 2, thereby make to flexibly connect between axle 5 and dolly end carriage 2 and have small free-running fit, can there is certain lateral adjustment, and then can realize in the situation that track installation parallelism error is large, prevent that the phenomenon of gnawing rail from occurring.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
