Abstract
The present invention discloses a kind of 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) hinged by bearing pin (1); also comprise backplate (5) and slide block (2); backplate (5) inner side has chute; backplate (5) one end is hinged on supporting leg assembly (7) by bearing pin (1), and slide block (2) is fixed on support oil cylinder (6), and the chute inside backplate (5) other end and slide block (2) are nested.The present invention has added backplate on support oil cylinder, support oil cylinder secures slide block, and backplate covers on slide block, slide block and backplate CONTACT WITH FRICTION when support oil cylinder stretches, prevent the hard object such as sandstone from contacting with support oil cylinder push rod and damage support oil cylinder push rod, extend the support oil cylinder life-span.
Description
Technical field
The present invention relates to a kind of loader-digger support oil cylinder protection mechanism, belong to loader component technology field.
Background technology
Loader-digger is commonly called as two and hurries, be a kind of collect excavate be loaded into one Versatile Construction Machinery.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, and can be engaged in the several work such as excavation, shovel dress, delivery and smooth location, be the desirable type 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 oil cylinder leakage of oil, the hydraulic lock often problem such as inoperative, shorten the application life of oil cylinder and hydraulic lock greatly, increase the maintenance cost of complete machine.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of loader-digger support oil cylinder protection mechanism, prevent the hard object such as sandstone from damaging support oil cylinder push rod, extend the support oil cylinder life-span.
To achieve these goals; the technical solution used in the present invention 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 pass through together with hinge; also comprise backplate and slide block, inside backplate, have chute, backplate one end by hinge on supporting leg assembly; slide block is fixed on support oil cylinder, and the chute inside the backplate other end and slide block 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, are welded with stiffener between two baffle plates.
Further, the material of slide block is nylon material.
Compared with prior art: the present invention has added backplate on support oil cylinder, support oil cylinder secures slide block, backplate covers on slide block, slide block and backplate CONTACT WITH FRICTION when support oil cylinder stretches, prevent the hard object such as sandstone from contacting with support oil cylinder push rod and damage support oil cylinder push rod, extend the support oil cylinder life-span.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1; this loader-digger support oil cylinder protection mechanism; comprise supporting leg assembly 7 and support oil cylinder 6; it is hinged that supporting leg assembly 7 and support oil cylinder 6 pass through bearing pin 1; also comprise backplate 5 and slide block 2, have chute inside backplate 5, backplate 5 one end is hinged on supporting leg assembly 7 by bearing pin 1; slide block 2 is fixed on support oil cylinder 6, and the chute inside backplate 5 other end and slide block 2 are nested.
Support oil cylinder 6 has added backplate 5, support oil cylinder 6 secures slide block 2, backplate 5 covers on slide block 2, slide block 2 CONTACT WITH FRICTION in the chute of backplate 5 when support oil cylinder 6 stretches, all the time the spacing between backplate 5 and support oil cylinder 6 push rod is ensured, and move angle to follow support oil cylinder 6 action by bearing pin 1 self-regulating rotary, prevent the hard object such as sandstone from contacting with support oil cylinder 6 push rod the push rod damaging support oil cylinder 6, extend support oil cylinder 6 life-span.
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 baffle plate 3, is welded with stiffener 4 between two baffle plates 3.
Protect the effect of support oil cylinder 6 to further improve slide block 2 and backplate 5, the material of slide block 2 is nylon material.
