Abstract
The invention provides a bridge of a bridge crane. The bridge comprises several wheel groups and end carriages, wherein two ends of each of the ends carriage are respectively provided with an accommodating slot to arrange the wheel groups; and the two ends of each of the end carriages are also provided with several positioning blocks. By arranging the positioning blocks on the two ends of each of the end carriages of the bridge of the bridge crane, the shearing resistances of the end carriages is improved, so the overall strengths of the end carriages are improved, and the safety of the bridge crane is improved.
Description
Technical field
The present invention relates to a kind of crane in bridge type, relate in particular to a kind of Overhead Crane Bridge.
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 crane span structure 100 of crane in bridge type is arranged near the end at end carriage 10 two ends, and vertically is installed on the longitudinal extension direction of end carriage, is 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.
Set of wheels is mainly through being bolted to the end, two ends of end carriage.Because the total weight of crane in bridge type is very big, and tens tons even hundreds of ton are generally arranged.So only rely on the bolted set of wheels may cause hoisting crane after long-time the use, because bolt aging or get rusty causes the cart set of wheels to remove original fixed position, thereby produces dangerous.Simultaneously,, the set of wheels position is installed especially, mainly carries shearing because general end carriage all be a hollow structure, its shear resistance ability relatively a little less than, thereby can there be certain potential safety hazard in the possible undercapacity that cause end carriage.
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 of crane in bridge type, improve the shear resistance of end carriage, improve the bulk strength of end carriage, thereby improve the safety of crane in bridge type.
For realizing the foregoing invention purpose, the present invention provides a kind of crane span structure of crane in bridge type, and it comprises
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;
End, said end carriage two ends also is provided with some locating pieces.
As further improvement of the present invention, said locating piece is arranged on the web of end, said end carriage two ends.
As further improvement of the present invention, said locating piece is periphery and is arranged at the edge of said accepting groove.
As further improvement of the present invention, any end end of said crane span structure is provided with two locating pieces at least.
Compared with prior art, the invention has the beneficial effects as follows: the end, end carriage two ends through at the crane span structure of crane in bridge type also is provided with some locating pieces, improves the shear resistance of end carriage, thereby improves the bulk strength of end carriage, and the safety that can improve crane in bridge type.

Fig. 1 is the end carriage of crane span structure in the prior art and the assembling scheme drawing of set of wheels;
Fig. 2 is the end carriage of crane span structure in a kind of Overhead Crane Bridge of the present invention and the assembled front view of set of wheels;
Fig. 3 is the lateral plan of the end carriage of crane span structure in the Overhead Crane Bridge shown in Figure 2.
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 the end carriage 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, end, said end carriage 10 two ends respectively is provided with an accepting groove 20, in order to set of wheels 30 to be installed.This end, end carriage 10 two ends also is provided with some locating pieces 50.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.
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, and the opening direction of this accepting groove 20 is identical with the longitudinal extension direction of said end carriage 10.Like this, set of wheels 30 is in the process that is installed in end carriage 10, in the accepting groove 20 of the end carriage 10 of just can packing into from the side.In this embodiment, this end, end carriage 10 two ends also is provided with two locating pieces 50.
Shown in Figure 3 in conjunction with reference, this accepting groove 20 is arranged at the end, two ends of end carriage 10.This locating piece 50 is arranged on the web 101 of end, said end carriage 10 two ends.This locating piece 50 is periphery and is arranged at the edge of this accepting groove 20.
These end carriage 10 any end ends are provided with two locating pieces 50 at least.In this embodiment, respectively be provided with two locating pieces 50 on the web 101 of the end, two ends of end carriage 10, also a locating piece 50 can be set respectively certainly.
After set of wheels 30 was installed in the accepting groove 20, bearing seat (not shown) used 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.At this moment, on the web 101 of end, end carriage 10 two ends, and be periphery, through modes such as welding, locating piece 50 be fixed on the web 101, thereby fix this bearing seat through locating piece 50 in the edge of this accepting groove 20, thus this set of wheels 30 of fixing effectively.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.
