Abstract
The utility model discloses an anti-dropping connecting hinge pin for a hydraulic crusher and an excavator, and belongs to the technical field of engineering machinery. The anti-dropping connecting hinge pin structurally comprises a hinge pin, bushings, welding rings, shells, an anti-dropping hinge pin, a flat washer and a cotter pin, wherein the bushings are arranged at the upper end and the lower end of the hinge pin, the welding rings are fixed onto the bushings, the shells are arranged on outsides of the welding rings, the anti-dropping hinge pin is arranged at a side end of the hinge pin, the cotter pin is arranged at the lower end of the anti-dropping hinge pin, and the flat washer is arranged at a joint of the anti-dropping hinge pin and the hinge pin. Outer hexagon bolts and a nut of an existing product are modified, a combination structure comprising the anti-dropping hinge pin, the additional flat washer and the cotter pin is adopted, and accordingly the anti-dropping connecting hinge pin has the advantages that the anti-dropping connecting hinge pin is convenient to maintain, the hitting force is increased, loosening and dropping of the hinge pin are effectively prevented, potential safety hazards are eradicated completely, the work efficiency is greatly improved, and the like.
Description
Technical field
The utility model relates to the slip-off preventing linkage in a kind of engineering machinery, is specifically related to a kind of hydraulic burster and is connected bearing pin with the excavator slip-off preventing.
Background technology
The New Hydraulic Impact Machine that hydraulic breaking hammer grew up the sixties in last century, take hydraulic pump as power source, oil liquid pressure is power, reciprocating motion of the pistons output impulse machine, utilize high-speed motion to impact bit shank, carry out crushing operation, obtained using comparatively widely with the boundary that digs up mine at engineering field.
Hydraulic burster is a kind of new and effective hydraulic shock vibration facility, auxiliary work parts of excavator or loader, realize the high-frequency reciprocating motion of destroyer piston in cylinder body with the hydraulic oil of machine-tool output during work, thereby hit drill steel, externally acting.
Hydraulic burster is widely used in the fields such as metallurgy, mine, railway, highway, building, urban construction, house exploitation, to the hard thing such as rock, concrete, ladle, slag, frozen soil, ice cube, cement pavement, bridge pier, building exploit, the operation such as fragmentation, dismounting.
As shown in Figure 1, the existing product that uses in the market, due to hydraulic breaking hammer in when work, can produce very big bang, destroyer is connected bearing pin with loader slip-off preventing position is to adopt two nuts and tight methods of pinning hex bolts, and this kind fixed form is unreliable, vibrations in hydraulic breaking hammer work are easy to make nut loosening and come off, there is certain potential safety hazard, and affects operating efficiency, the problems such as maintenance inconvenience.
Summary of the invention
In order to solve deficiency of the prior art, the utility model provides a kind of hydraulic burster to be connected bearing pin with the excavator slip-off preventing, has the advantages such as topology layout is reasonable, simple in structure, easy to maintenance, hitting dynamics increases, operating efficiency improves, easy to use.
The utility model is to realize by following technical scheme:
A kind of hydraulic burster is connected bearing pin with the excavator slip-off preventing, its structure is made of: bearing pin, lining, welding circle, shell, anti-break pin, plain washer, cottor pin, wherein the two ends up and down of bearing pin are provided with lining, the welding circle is fixed on lining, and the outer setting of welding circle has shell, the side of bearing pin is provided with anti-break pin, and the lower end of anti-break pin is provided with cottor pin, and the junction of anti-break pin and bearing pin is provided with plain washer.
Described lining, it is provided with groove, and the welding circle is positioned in lining.
The utility model is by improving outer-hexagonal bolt and nut in existing product, and adopt anti-break pin, add the combining structure of plain washer and cottor pin, has easy to maintenance, hitting dynamics increase, effectively prevent the loosening of bearing pin and come off, stopped potential safety hazard, operating efficiency such as improves greatly at the advantage.

In Fig. 2: 1-bearing pin, 2-lining, 3-welding circle, 4-shell, 5-anti-break pin, 6-plain washer, 7-cottor pin.
The specific embodiment:
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Figure 2, a kind of hydraulic burster is connected bearing pin with the excavator slip-off preventing, its structure is made of: bearing pin 1, lining 2, welding circle 3, shell 4, anti-break pin 5, plain washer 6, cottor pin 7, wherein the two ends up and down of bearing pin 1 are provided with lining 2, welding circle 3 is fixed on lining 2, and the outer setting of welding circle 3 has shell 4, and the side of bearing pin 1 is provided with anti-break pin 5, the lower end of anti-break pin 5 is provided with cottor pin 7, and the junction of anti-break pin 5 and bearing pin 1 is provided with plain washer 6.
Described lining 2, it is provided with groove, and welding circle 3 is positioned in lining 2.
The utility model is by improving outer-hexagonal bolt and nut in existing product, and adopt anti-break pin, add the combining structure of plain washer and cottor pin, has easy to maintenance, hitting dynamics increase, effectively prevent the loosening of bearing pin and come off, stopped potential safety hazard, operating efficiency such as improves greatly at the advantage.
It should be noted that at last: above manual is only in order to illustrate the technical solution of the utility model and use characteristic, although this manual has been described in detail the utility model with reference to the above embodiments, but, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in claim scope of the present utility model.
