In addition, term " first ", " second " be only be used to describing purpose, and can not be interpreted as indication or hint relative importance or the implicit quantity that indicates indicated technical characterictic.Thus, one or more these features can be expressed or impliedly be comprised to the feature that is limited with " first ", " second ".In description of the present utility model, the implication of " a plurality of " is two or more, unless otherwise expressly limited specifically.
In the utility model, unless otherwise clearly defined and limited, broad understanding should be done in the terms such as term " installation ", " being connected ", " connection ", " fixing ", for example, can be to be fixedly connected with, and can be also to removably connect, or connect integratedly; Can be mechanical connection, can be also to be electrically connected to; Can be directly to be connected, also can indirectly be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term in the utility model.
For caterpillar belt structure in existing crawler crane, need to promote the tensioner that track adjusting wheel or the second drive wheel are realized caterpillar block by swelling device, make the problem of the portion structure complexity relatively moved, the utility model provides a kind of new caterpillar belt structure, front-wheel (track adjusting wheel or the second drive wheel) is designed to fix with respect to the track frame position, and support roller is designed to adjustable with respect to the track frame upper-lower position, thereby can be when the assembling caterpillar block, by adjusting the position of support roller, both can guarantee the connection of caterpillar block, can after connecting, realize caterpillar block the tensioner of caterpillar block again.
Caterpillar belt structure of the present utility model can be applied in little tonnage caterpiller crane, also can be applied in the large-tonnage crawler crane.
As shown in Figure 3, be the view of a kind of caterpillar belt structure of the present utility model before the caterpillar block tensioner, Fig. 4 is the view of this caterpillar belt structure after the caterpillar block tensioner.
Caterpillar belt structure of the present utility model comprises: drive wheel 1, support roller 2, caterpillar block 3, track frame 4, front-wheel 9 and BOGEY WHEEL 21.Wherein caterpillar block 3 is laid on track frame 4, and the two ends of caterpillar block 3 are connected.
Different from existing caterpillar belt structure is that in caterpillar belt structure of the present utility model, front-wheel 9 is arranged in the front groove of track frame 4, and fixes with respect to track frame 4 positions.That is to say, the position of front-wheel 9 immobilizes before and after caterpillar block 3 assemblings, does not need to adjust.And support roller 2 is arranged on the rear and front end of track frame 4, and adjustable with respect to track frame 4 upper-lower positions, to realize the tensioner of caterpillar block.
Particularly, as shown in Figure 5, support roller 2 can be arranged on track frame 4 by adjustable bolt 12.When the assembling crawler belt, first support roller 2 is arranged on to primary importance; After caterpillar block had been arranged, adjusting bolt 12 moved to the second place by support roller 2, wherein the second place above primary importance, thereby can make caterpillar block 3 tensioners.
In order to guarantee that support roller 2 is securely fixed in to the second place, as shown in Figure 5, can utilize the fixing described support roller 2 of support roller connecting element 10.
Support roller connecting element 10 is arranged between described primary importance and the described second place.In concrete application, above-mentioned support roller connecting element 10 can be pad, can be also other parts that can fix described support roller, and this utility model is not done to restriction.
In order further to improve the tensioner effect of caterpillar block 3, as shown in Figure 4, also can comprise in caterpillar belt structure of the present utility model: carriage 11, after support roller 2 moves to the second place, is arranged on track frame 4 carriage 11 position between former and later two support rollers.
Below continuation describes the assembling process of caterpillar belt structure of the present utility model in detail in conjunction with Fig. 3 and Fig. 4.
When assembling caterpillar block 3, support roller 2 is arranged on to track frame 41 by adjustable bolt 12, and is fixed on primary importance, required whole caterpillar blocks 3 are assembled, and be laid on track frame 4, the two ends of caterpillar block 3 are connected to (see figure 3).Then, utilize the instrument such as spanner to turn adjustable bolt 12, make support roller 2 to the second place, and on track frame 4 installation bracket 11, support roller connecting element 10(is installed sees Fig. 4 between installation site 1 and installation site 2).
On primary importance and track frame 4 not during installation bracket 11, the distance of the caterpillar block 3 above track frame 4 and following caterpillar block 3 is little, can guarantee the connection of caterpillar block 3 due to support roller 2.When support roller 2 is installed to the second place, due to the second place, higher than primary importance, make caterpillar block 3 above track frame 4 and the distance of following caterpillar block 3 become large, realized the tensioner of caterpillar block 3.During by installation bracket 11 on track frame 4, caterpillar block 3 above track frame 4 and the distance of following caterpillar block 3 are further strengthened, strengthen the tensioner effect of caterpillar block 3.
It should be noted that, caterpillar belt structure of the present utility model can be applied in little tonnage caterpiller crane, also can be applied in the large-tonnage crawler crane, can make its running gear simple in structure, improves walking performance.While being applied in little tonnage caterpiller crane, front-wheel 9 can adopt track adjusting wheel, and while being applied in the large-tonnage crawler crane, front-wheel 9 can adopt drive wheel, the function that has guiding concurrently and drive, the power-handling capability of raising crane running system.
Visible, caterpillar belt structure of the present utility model, be designed to support roller adjustable with respect to the track frame upper-lower position, thereby can be when the assembling caterpillar block, by adjusting the position of support roller, both can guarantee the connection of caterpillar block, can after connecting, realize caterpillar block the tensioner of caterpillar block again.Because support roller is different from installation site and the stressing conditions of front-wheel, support roller is arranged on track frame, and stressed little with respect to front-wheel, therefore, with respect to prior art, being arranged on the front-wheel in groove before track frame by adjustment is the frame mode that track adjusting wheel or the second drive wheel are realized the caterpillar block tensioner, can greatly simplify the structure of track frame, and realize easily the tensioner of caterpillar block.And, in caterpillar belt structure of the present utility model, do not need swelling device, effectively provide cost savings.
Above the utility model embodiment is described in detail, has applied the specific embodiment herein the utility model is set forth, the explanation of above embodiment is just be used to helping to understand method and apparatus of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
