Abstract
The utility model discloses a supporting leg oil cylinder protection mechanism for a loader-digger. The supporting leg oil cylinder protection mechanism comprises a supporting leg assembly (7) and a supporting leg oil cylinder (6), wherein the supporting leg assembly (7) and the supporting leg oil cylinder (6) are hinged together; the supporting leg oil cylinder protection mechanism also comprises a protection plate (5) and a sliding block (2); a sliding chute is formed in the inner side of the protection plate (5); one end of the protection plate (5) is hinged to the supporting leg assembly (7) through a pin shaft (1); the sliding block (2) is fixed on the supporting leg oil cylinder (6); the sliding chute in the inner side of the other end of the protection plate (5) is embedded with the sliding block (2). According to the supporting leg oil cylinder protection mechanism for the loader-digger, the protection plate is additionally arranged on the supporting leg oil cylinder; the sliding block is fixed on the supporting leg oil cylinder; the protection plate covers the sliding block; when the supporting leg oil cylinder stretches, the sliding block is in friction contact with the protection plate, so that the phenomenon that a push rod of the supporting leg oil cylinder is damaged due to a fact that hard substances such as gravels are in contact with the push rod of the supporting leg oil cylinder is avoided; the service life of the supporting leg oil cylinder is prolonged.
Description
Technical field
The utility model relates to a kind of loader-digger support oil cylinder protection mechanism, belongs to loader component technology field.
Background technology
It is busy that loader-digger is commonly called as two, is a kind of collection to excavate the Versatile Construction Machinery that is loaded into one.Complete machine rational and compact, handsome in appearance, operation comfort and convenient, turning radius is little, favorable working performance, cost performance are high.It is widely used in the construction of the object of construction production such as municipal administration, building, oil field, water conservancy, forest farm, military engineering, can be engaged in the several work such as excavation, shovel dress, delivery and smooth location, is the desirable type of realizing a tractor serves several purposes.But in actual use, the direct kiss the earth of supporting leg, support oil cylinder push rod and hydraulic lock are easy to be damaged by materials such as sandstones, cause the scuffing of colliding with of push rod and hydraulic lock, and then cause the often problem such as inoperative of oil cylinder leakage of oil, hydraulic lock, shorten greatly the application life of oil cylinder and hydraulic lock, strengthened the maintenance cost of complete machine.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of loader-digger support oil cylinder protection mechanism, prevents that the hard things such as sandstone from damaging support oil cylinder push rod, extended the support oil cylinder life-span.
To achieve these goals; the technical solution adopted in the utility model is: a kind of loader-digger support oil cylinder protection mechanism; comprise supporting leg assembly and support oil cylinder; supporting leg assembly and support oil cylinder are hinged by bearing pin; also comprise backplate and slide block, backplate inner side has chute, and backplate one end is hinged on supporting leg assembly by bearing pin; slide block is fixed on support oil cylinder, and chute and the slide block of backplate other end inner side are nested.
Further, backplate is made up of bent plate, stiffener and baffle plate, and the both sides, one end of bent plate are welded with baffle plate, between two baffle plates, are welded with stiffener.
Further, the material of slide block is nylon material.
Compared with prior art: the utility model has added backplate on support oil cylinder, on support oil cylinder, fix slide block, backplate covers on slide block, slide block and backplate CONTACT WITH FRICTION in the time that support oil cylinder is flexible, prevent that the hard things such as sandstone from contacting damage support oil cylinder push rod with support oil cylinder push rod, extended the support oil cylinder life-span.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model backplate front view;
Fig. 3 is the utility model backplate top view;
Fig. 4 is the utility model backplate lateral view.
In figure: 1, bearing pin, 2, slide block, 3, baffle plate, 4, stiffener, 5, backplate, 6, support oil cylinder, 7, supporting leg assembly, 8, bent plate.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1; this loader-digger support oil cylinder protection mechanism; comprise supporting leg assembly 7 and support oil cylinder 6; supporting leg assembly 7 and support oil cylinder 6 are hinged by bearing pin 1; also comprise backplate 5 and slide block 2, backplate 5 inner sides have chute, and backplate 5 one end are hinged on supporting leg assembly 7 by bearing pin 1; slide block 2 is fixed on support oil cylinder 6, and chute and the slide block 2 of backplate 5 other end inner sides are nested.
On support oil cylinder 6, add backplate 5, on support oil cylinder 6, fix slide block 2, backplate 5 covers on slide block 2, slide block 2 CONTACT WITH FRICTION in the chute of backplate 5 in the time that support oil cylinder 6 is flexible, all the time guarantee the spacing between backplate 5 and support oil cylinder 6 push rods, and can, by the moving angle of bearing pin 1 self-regulating rotary so that following support oil cylinder 6 moves, prevent that the hard things such as sandstone from contacting the push rod that damages support oil cylinder 6 with support oil cylinder 6 push rods, extended 6 life-spans of support oil cylinder.
As shown in Figures 2 to 4, backplate 5 is made up of bent plate 8, stiffener 4 and baffle plate 3, and the both sides, one end of bent plate 8 are welded with between baffle plate 3, two baffle plates 3 and are welded with stiffener 4.
The effect of protecting support oil cylinder 6 in order further to improve slide block 2 and backplate 5, the material of slide block 2 is nylon material.
