The beneficial effects of the utility model are the stability of crawler crane when counterweight is installed behind further effective the raising, and greatly facilitate the installation of bearing pin between back counterweight and the main platform, counterweight loadingunloading time behind the saving hoisting crane.
Description of drawings
By reading the detailed description of non-limiting example being done with reference to following accompanying drawing, it is more obvious that other features, objects and advantages of the present utility model will become:
Fig. 1 illustrates according to back of the present utility model counterweight pallet scheme drawing;
Fig. 2 illustrates according to installation view of the present utility model; And
Fig. 3 is the local enlarged diagram of Fig. 2.
The specific embodiment
Come a kind of dynamic compaction machinery turn table shock absorber of the present utility model is done explanation in further detail below in conjunction with specification drawings and specific embodiments.
Fig. 1 illustrates according to back of the present utility model counterweight pallet scheme drawing.In conjunction with counterweight integral part behind the reference self-assembling and disassembling rear counterweight of crawler crane mainframe device main frame of the present utility model shown in Figure 3, counterweight comprises back counterweight lifting frame 1, main platform 7, back counterweight pallet 3, hydraulic ram 2 and lifting plate 6 behind the described self-assembling and disassembling rear counterweight of crawler crane mainframe device main frame, also comprise orienting sleeve 5, described back counterweight pallet 3 is provided with the axis of guide 301, flanged plate 302.Particularly, back counterweight lifting frame 1 one ends and hydraulic ram 2 are connected by bearing pin, the other end also is connected by bearing pin with lifting plate 6, lifting plate 6 is welded on the counterweight pallet of back, hydraulic ram 2 is fixed on main platform 7 afterbodys, through hole is set on main platform 7 base plates forms orienting sleeve 5, the axis of guide 301 1 ends are welded on the flanged plate 302, the other end coning, described flanged plate 302 is by being bolted on the counterweight pallet of back, further, back counterweight pallet 3 is provided with pin-and-hole 303, main platform 7 also is provided with the pin-and-hole (not shown), and the pin-and-hole location overlap on main platform 7 and the back counterweight pallet 3 is used for bearing pin and connects.
As shown in Figure 1, in one embodiment, the lifting plate that is welded on the back counterweight pallet 3 is 4, is welded on symmetrically respectively on the back counterweight pallet 3.Fix 2 axis of guides on the back counterweight pallet 3, accordingly, the quantity of orienting sleeve 5 also is 2 on the main platform 7, further, the position of the axis of guide 301 on the counterweight pallet 3 after the position correspondence of orienting sleeve 5 on the described main platform 7 makes that orienting sleeve 5 can just in time entangle the axis of guide 301 when counterweight was installed.The position of pin-and-hole is arranged on the outside of the axis of guide 301 on the back counterweight pallet 3.
Change in the example at one, the quantity of the lifting plate 6 on the described back counterweight pallet 3 can also be 8 and be welded on 4 axisymmetric positions on the counterweight pallet 3 of back respectively, the common back counterweight lifting frame 1 that connects.
Change in the example at another, the position of the axis of guide 301 and the position of pin-and-hole 303 can be changed on the counterweight pallet 3 of described back, correspondingly, orienting sleeve 5 on the main platform 7 also adopts different layouts with the pin-and-hole position on the main platform 7, the position of the axis of guide 301 and the position of pin-and-hole 303 on the counterweight pallet 3 of corresponding respectively back.
Fig. 2 illustrates according to installation view of the present utility model.Particularly, with reference to local enlarged diagram of the present utility model shown in Figure 3, as shown in Figure 3, described back counterweight pallet 3 is liftoff and be promoted to the contact position of platform under the lifting of back counterweight lifting frame 1, and wherein, hydraulic reservoir 2 strokes stretch out, counterweight pallet 3 after back counterweight lifting frame 1 is sling by chain sling connection lifting plate 6, the axis of guide 4 inserts orienting sleeve 5, forms a constraint, is convenient to the location.
When implementing the utility model, hydraulic ram 2 strokes stretch out, promote back counterweight lifting frame 1, make back counterweight 3 supporting plates rise, because being bearing pins, back counterweight 3 supporting plates connect back counterweight lifting frame 1, have when rising at back counterweight pallet 3 and to tilt forward and back, when back counterweight pallet 3 rises to liftoff certain altitude, the axis of guide 4 enters orienting sleeve 5, owing to increased a constraint, the situation that back counterweight pallet 3 tilts forward and back is eliminated, and again through one section guiding distance, contacts with back counterweight pallet 3 on the main platform 7, because the constraint of the axis of guide 4 and orienting sleeve 5, pin-and-hole energy automatic centering on pin-and-hole on the main platform 7 and the back counterweight pallet 3, the at this moment very convenient pin of putting on is finished the whole erection step.
Similarly, the process of dismounting is opposite with said process, has adopted the utility model, also can increase the stability of back counterweight in unloading process.
More than specific embodiment of the utility model is described.It will be appreciated that the utility model is not limited to above-mentioned specific implementations, wherein equipment of not describing in detail to the greatest extent and structure are construed as with the common mode in this area and are implemented; Those skilled in the art can make various distortion or modification within the scope of the claims, and this does not influence flesh and blood of the present utility model.
