Abstract
The invention provides a bridge of a bridge crane. The bridge at least comprises several wheel groups and an end carriage, wherein two ends of the end carriage are respectively provided with an accommodation slot to arrange the wheel groups; and installation directions of the wheel groups to the accommodation slots are same as the vertical extension direction of the end carriage. Above structure has the advantages of simple replacement of the wheel groups, reduction of the manpower cost for replacing the wheel groups, and reduction of the danger of maintenance people during wheel group replacement.
Description
Technical field
The present invention relates to a kind of crane in bridge type, relate in particular to a kind of crane span structure of crane in bridge type.
Background technology
As everyone knows, crane in bridge type generally comprises: electric apparatus, crane span structure, dolly, traveling mechanism of the larger traveller etc.Wherein, the keystone configuration of crane span structure is girder and end carriage.
Join shown in Figure 1ly, in the prior art, the set of wheels 30 of the end carriage 10 of each crane span structure 100 is arranged near the end at end carriage 10 two ends, and vertically is installed on the longitudinal extension direction of end carriage 10.Be installed in like arrow direction among Fig. 1 in the accepting groove 20 of end carriage 10.Bearing seat (not shown) uses bolt that bearing seat is fixed in the screw 401 through the flange 40 on accepting groove 20 limits, thus fixing set of wheels 30.
So when the assembling wheels group, need the crane span structure end carriage be lifted.Because the weight of whole crane in bridge type is huge, and tens tons even hundreds of ton are generally arranged.So in manufacturing process, particularly in the maintenance process after installation, needing to use the jack crane in bridge type that weight is huge to lift higher height could the change of wheels group.So just exist set of wheels to change the problem of difficulty.Simultaneously, the step of change of wheels group is also comparatively loaded down with trivial details, and human cost is bigger, also has certain danger.
In view of this, be necessary the crane span structure of crane in bridge type is improved, to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of crane span structure end carriage of crane in bridge type, but the replacing of its compact car wheels, the human cost of reduction change of wheels group, the danger when reducing maintainer's change of wheels group simultaneously.
For realizing the foregoing invention purpose, the present invention provides a kind of crane span structure of crane in bridge type, and it comprises at least
Some set of wheels, and
End carriage, end, said end carriage two ends respectively is provided with an accepting groove, in order to set of wheels to be installed;
The installation direction of said set of wheels and accepting groove is identical with the longitudinal extension direction of said end carriage.
As further improvement of the present invention, the opening direction of said accepting groove is identical with the longitudinal extension direction of said end carriage.
As further improvement of the present invention, said accepting groove is arranged at the end, two ends of end carriage.
Compared with prior art; The invention has the beneficial effects as follows:,, only need to use jack that crane in bridge type one end is lifted even need the change of wheels group through the identical such setting of longitudinal extension direction of set of wheels with the installation direction and the said end carriage of the accepting groove of end carriage; Set of wheels and track are got final product; The set of wheels of end, end carriage two ends that can easy crane span structure end carriage is changed, and reduces the human cost of change of wheels group, the danger when reducing maintainer's change of wheels group simultaneously.
Description of drawings
Fig. 1 is the assembling scheme drawing of prior art jackshaft frame end beam and set of wheels;
Fig. 2 is the end carriage in crane span structure one specific embodiment of a kind of crane in bridge type of the present invention and the assembling scheme drawing of set of wheels.
The specific embodiment
Below in conjunction with each embodiment shown in the drawings the present invention is elaborated; But should be noted that; These embodiments are not limitation of the present invention; The function that those of ordinary skills do according to these embodiments, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Join crane span structure one specific embodiment of a kind of crane in bridge type of the present invention shown in Figure 2.In this embodiment, a kind of crane span structure 100 of crane in bridge type, it comprises some set of wheels 30, and end carriage 10, this end, end carriage 10 two ends respectively is provided with an accepting groove 20, in order to set of wheels 30 to be installed.Bearing seat (not shown) uses bolt that bearing seat is fixed in the screw 401 through the flange 40 on accepting groove 20 limits, thus fixing set of wheels 30.In this embodiment, flange 40 is arranged on the web 101 of end, two ends of end carriage 10.
The opening direction of this accepting groove 20 is identical with the longitudinal extension direction of said end carriage 10.This crane span structure 100 also comprises the some set of wheels 30 that are arranged on end, said end carriage 10 two ends.The installation direction of this set of wheels 30 and accepting groove 20 is identical with the longitudinal extension direction of end carriage 10.Like this, set of wheels 30 just can be from the web 101 of end carriage 10 be packed the accepting groove 20 of end carriage 10 in the process that is installed in end carriage 10.In this embodiment, the crane span structure 100 of this crane in bridge type can comprise four end carriages 10.
The listed a series of detailed description of preceding text only is specifying to feasibility embodiment of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and under the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, scope of the present invention is limited accompanying claims rather than above-mentioned explanation, therefore is intended to the implication of the equivalents that drops on claim and all changes in the scope are included in the present invention.Should any Reference numeral in the claim be regarded as limit related claim.
In addition; Describing according to embodiment though should be appreciated that this specification sheets, is not that each embodiment only comprises an independently technical scheme; This narrating mode of specification sheets only is for clarity sake; Those skilled in the art should make specification sheets as a whole, and the technical scheme among each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
