Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
The slide block occurred after principal arm is repeatedly flexible for solving combined sliding block of the prior art is scattered problem, the utility model provides a kind of combination bar shaped slide block 1, comprise metal block 1-1 and nylon sheet 1-2, the middle part of described metal block 1-1 is provided with groove, the middle part of described nylon sheet 1-2 is provided with the boss cooperatively interacted with the groove of described metal block 1-1, described metal block 1-1 superposes mutually with described nylon sheet 1-2, and is fixedly connected with by screw 1-3.The structure design of the groove of described metal block 1-1 and the boss of described nylon sheet 1-2, can limit the movable of described metal block 1-1 and nylon sheet 1-2.
Described metal block 1-1 is preferably iron slider, can also be copper silumin, aluminium slide block etc. certainly, as long as the intensity of this metal block 1-1 is greater than the slide block intensity of nylon material.
Compared to the slide block of nylon material pure in prior art, the structural strength of the combination bar shaped slide block 1 that the utility model provides is larger, combining, its resistance when bar shaped slide block 1 is subject to application force is larger, effectively can solve the problem that slide block is scattered when being applied to slide block assembly.
As shown in Figure 4, the reverse side that described nylon sheet 1-2 contacts with described metal block 1-1 can be provided with counter sink 2, described screw 1-3 is installed in described counter sink 2, described screw 1-3 is made not to be exposed to outside nylon sheet 1-2 like this, not first-class with cargo boom metal parts directly contacts, and avoids the surface scratching the metal parts directly contacted with described combination bar shaped slide block 1.
For achieving the above object, the utility model additionally provides a kind of slide block assembly, as shown in Figure 5, is the structural representation of an embodiment of the utility model slide block assembly.This slide block assembly comprises front apron 3, back shield 4 and some bar shaped slide blocks 5, described bar shaped slide block 5 is nylon material, the two ends of described bar shaped slide block 5 are fixed on described front apron 3 and described back shield 4 respectively by bolt 6, have one in described some bar shaped slide blocks 5 at least for above-mentioned combination bar shaped slide block 1, and have at least a described combination bar shaped slide block 1 to be positioned at the midway location of described slide block assembly.
One or more above-mentioned combination bar shaped slide block 1 can be comprised in this slide block assembly, above-mentioned combination bar shaped slide block 1 can certainly be by all bar shaped slide blocks 5, but at least an above-mentioned combination bar shaped slide block 1 will be set at midway location.Here midway location refers to the midway location of the circular arc that whole slide block assembly simulates, and as shown in Figure 5, under general operating mode, the circular arc midway location that described slide block assembly simulates is the maximum position of pressurized.When described bar shaped slide block 5 add up to even number time, the quantity of the described bar shaped slide block 5 of the both sides of described combination bar shaped slide block 1 is identical; When described bar shaped slide block 5 add up to odd number time, the quantity of the described bar shaped slide block 5 of the both sides of described combination bar shaped slide block 1 differs one.
In one embodiment, described slide block assembly can also comprise two jam plates 7, on the left slider 8 that described two jam plates 7 are embedded in described slide block assembly two ends respectively and right slide block 9, described jam plate two ends are provided with and hook plate 10, described hook plate 10 can catch on the end of described front apron 3 and back shield 4, and is connected by bolt 6.Wherein, described jam plate 7 can be metal latch plate, also can be the jam plate, steel jam plate etc. of the jam plate of other materials, such as alloy material, as long as its intensity can bear External Force Acting.
In one embodiment, described jam plate 7 can be formed in one with described front apron 3 or back shield 4, like this can simplified structure, convenient for assembly.
In one embodiment, described slide block assembly can also comprise pad, and described pad is sheathed on described bolt 6, can push bolt 6, bolt is connected more reliably fastening.Described pad can be spring washer, and the effect of spring washer prevents from bolt from connecting to loosen.Described bar shaped slide block 5 and described combination bar shaped slide block 1 also can sheathed spring washers with the tie bolt of described front apron 3 and described back shield 4.
In one embodiment, this slide block assembly simulates circular shape by multiple bar shaped slide block assembling, for circular arc place under the cylindrical shell of the crane arm of box type telescopic boom crane, by arranging jam plate 7 at edge, combination bar shaped slide block 1 is set at the midway location of slide block assembly, changes the stress form of whole slide block assembly in the principal arm retraction process of crane arm.
When principal arm is overhanging, the friction force that bar shaped slide block 5 and combination bar shaped slide block 1 are subject to internal segment cylindrical shell outside, by directly power being delivered to front apron 3 with the contact relation of described front apron 3, connecting bar shaped slide block 5 in slide block assembly, combination bar shaped slide block 1 does not all stress with the bolt 6 of front apron 3 and back shield 4; During principal arm retraction, power is directly passed to front apron 3 by back shield 4 and jam plate 7 by bar shaped slide block 5, and the power be subject to is passed to metal block 1-1 by nylon sheet 1-2, and power is passed to front apron 3 by bolt 6 by metal block 1-1.
When slide block assembly is subject to friction force, the jam plate 7 being positioned at slide block assembly edge bears main internal segment cylindrical shell friction force, and combination bar shaped slide block 1 helps out.Simultaneously, in this slide block assembly, the intensity of described jam plate 7 is greater than the screw strength of described metal block 1-1, the screw strength of described metal block 1-1 is greater than the screw strength of the bolt when slide block connecting nylon material is connected with front apron or back shield, therefore the structural strength of this slide block assembly, namely slide block assembly self structure stablize, indeformable, the ability of not being scattered, depend primarily on the self-strength of jam plate, the problem that can slide block avoided better to be scattered.
Certainly, the material of jam plate and metal block can have a variety of selection, as long as their intensity can reach operating needs.Such as, jam plate can adopt high strength steel, and Materials Yield Limit is 960MPa; Metal block can adopt Q550 material, and Materials Yield Limit is 550MPa, and itself and bolt Joint strenght are less than high strength steel jam plate self-strength, and this is only an example certainly, does not form the restriction to material in the utility model.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
