Detailed description of the invention
First object of the present utility model is to provide a kind of caterpillar block, and the structure design of this caterpillar block can solve the yielding problem of caterpillar block effectively, and second object of the present utility model is to provide a kind of excavating machine that comprises above-mentioned caterpillar block.
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, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 2-Fig. 4, the caterpillar block that the utility model embodiment provides comprises channel-section steel 1 and steel plate 2, same as the prior art, channel-section steel 1 has diapire 12 and two relative sidewalls 11 that are connected with the both sides of diapire 12 respectively, two sidewalls 11 only a side be connected with diapire 12, opposite side forms the mouth end of channel-section steel 1.Steel plate 2 is fixedly connected with the two side 11 at the mouth end place of channel-section steel 1, and steel plate 2 is all fixedly connected with the side not being connected with diapire 12 of two side 11.So, steel plate 2 can cover the whole of 1 mouthful of end of channel-section steel, also can only cover the part of 1 mouthful of end of channel-section steel.
When caterpillar block that application the utility model embodiment provides, in the time of crawler travel, the steel plate 2 of caterpillar block directly contacts with ground, when there being harder material on ground, during such as stone granules, now stone granules directly contacts with steel plate 2, and the area of steel plate 2 is larger, in the time that it directly contacts with stone granules, pressure can be relatively little, is therefore difficult for producing distortion, and the channel-section steel 1 being fixedly connected with steel plate 2 is not yielding yet, and then make whole caterpillar block not yielding, thereby the connecting pin of connecting band track plate also can not cut off because of the distortion of caterpillar block again.
Preferably, in order further to optimize technique scheme, sidewall 11 outsides that the both sides of steel plate 2 can extend to channel-section steel 1 form extension edge 21, it is the width that the width of steel plate 2 can be greater than channel-section steel 1, so channel-section steel 1 sidewall 11 outsides can be stretched out in the both sides of steel plate 2, and extension edge 21 can tilt to the direction near diapire 12.So arrange, be more convenient to being fixedly connected with of steel plate 2 and channel-section steel 1, and the increase of the area of steel plate 2, make it more not yielding.Certainly, extension edge 21 also can not tilt, in this no limit.
In addition, the sidewall 11 of channel-section steel 1 can comprise interlude B and be positioned at the tilting section A of interlude B both sides, and the edge that is positioned at 1 mouthful of end place of channel-section steel of interlude B is parallel to diapire 12, the edge that is positioned at 1 mouthful of end of channel-section steel of tilting section A is to tilting near diapire 12 directions, be that sidewall 11 entirety are trapezoidal, long being connected with diapire 12 in two trapezoidal parallel edges.Interlude B and two tilting section A are arranged side by side along the length direction of sidewall 11.So arrange, be more convenient to excavating machine and advance in marshy area.Certainly, the edge that the sidewall 11 of channel-section steel 1 is positioned at 1 mouthful of end place of channel-section steel can be parallel to diapire 12 completely, in this no limit.Further, steel plate 2 can only be fixedly connected with the interlude B of sidewall 11, and the mouth that is positioned at interlude B that covers channel-section steel 1 is held, so cover monoblock steel plate 2 at the mouth end that is positioned at interlude B of channel-section steel 1, the area of steel plate 2 is larger, in the time directly contacting with stone granules, more not yielding, strengthen accordingly the intensity of this caterpillar block.
For the brace panel 13 of further strengthening the intensity of this caterpillar block, can also arrange in the groove of channel-section steel 1 arranging along its length direction and/or the brace panel 13 arranging along its Width.Wherein, brace panel 13 can be fixedly connected with by the mode of welding with channel-section steel 1.Further, brace panel 13 can and steel plate 2 between there is gap, be the width that the width of brace panel 13 is less than sidewall 11, the top of brace panel 13 is positioned at the inside grooves of channel-section steel 1, and steel plate 2 has gap between a side of groove, so arrange, in the time that steel plate 2 is out of shape, can not affect the distortion of brace panel 13, therefore can not affect the distortion of channel-section steel 1, reduce accordingly the deflection of channel-section steel 1, and then can not make connecting pin fracture.
Certainly, the top of brace panel 13 also can directly be fixedly connected with the side towards groove of steel plate 2, in this no limit.In addition, brace panel 13 also can be along length or the Width of channel-section steel 1, in this no limit.
In addition, the two side 11 of channel-section steel 1 can be fixedly connected with by the mode of welding with steel plate 2.Certainly can also be fixedly connected with by alternate manner, such as bolt or screw, in this no limit.
Based on the caterpillar block providing in above-described embodiment, the utility model also provides a kind of excavating machine, and this excavating machine comprises any one caterpillar block in above-described embodiment.Because this excavating machine has adopted the caterpillar block in above-described embodiment, so the beneficial effect of this excavating machine please refer to above-described embodiment.
In this specification sheets, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is and the difference of other embodiment, between each embodiment identical similar part mutually referring to.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
