Abstract
The utility model discloses a novel sliding plate framework sealing device for a grab bucket product. The device consists of a pin shaft, a manganese sleeve arranged on the pin shaft in a sleeving manner, and a rotating part fixedly connected with the manganese sleeve, wherein the end part of the manganese sleeve is sealed together with the shaft surface of the pin shaft through a sealing part; the sealing part consists of a gland, a sliding plate, a framework oil seal and a gasket; the gland is arranged on the end part of the manganese sleeve in a sleeving manner, and is fixedly connected with the rotating part; the sliding plate, the framework oil seal and the gasket, which are arranged on the pin shaft in a sleeving manner, are sequentially arranged between the gland and the end part of the manganese sleeve; the framework oil seal is fixedly connected with the sliding plate; the sliding plate radially slides relative to the manganese sleeve along the end face of the manganese sleeve. According to the device, dustproof and waterproof sealing effects on a large gap formed when the pin shaft and the manganese sleeve are abraded are achieved; lubricating grease is prevented from being leakage, and the maintenance cost is lowered; when the pin shaft sways relative to a manganese sleeve hole in the radial direction, the sealing part is difficult to damage, and a product is long in service life and high in practicability.
Description
Technical field
The utility model product belongs to machine industry, is specifically related to a kind of skeleton slide plate sealing device for the product of grabbing bucket.
Background technology
Grab bucket product is widely used in building, transportation, salvages the industries such as dredging, is of wide application.The essential structure of grab bucket product is that bucket body is connected with the manganese cover being enclosed within on bearing pin, and its bearing pin is installed on bolster and fixes, and grab bucket is when work, and bucket body captures material around bearing pin rotation and realizes the effects such as its handling, excavation, desilting.
Due to the reliability of grab bucket product needed member motion, it is large that each rotates designing requirement gap, connection place, and allowed compared with galling, do not affect grab bucket and normally use.Because crawled material easily enters in manganese trepanning, cause the accelerated wear test of bearing pin and other parts, reduced the service life of product, prior art, to adopting reinforced seal device, labyrinth gland etc. to seal between the bearing pin of grab bucket and its rotation aperture, plays the effect of water proof and dust proof.Can be with very large rocking and a small amount of play when rotating with respect to manganese trepanning but the problem existing is bearing pin, especially after hole and bearing pin wearing and tearing produce large gap, rock the damage that can cause sealing arrangement, water proof and dust proof effect is bad, and grab bucket safeguards that the grease of filling is because of large clearance leakage, do not have due lubricant effect, increased maintenance cost.
Summary of the invention
The purpose of this utility model is to have above-mentioned defect for prior art, slide plate reinforced seal device for a kind of novel grab bucket product is provided, after the bearing pin of grab bucket product produces large gap with rotation aperture because of wearing and tearing, sealing member still keeps its leak tightness, stop foreign matter to enter, prevent that lubricating grease from leaking; When bearing pin radially rocks with respect to manganese trepanning, sealing member is difficult for damaged, has extended the service life of product, has reduced maintenance cost.
The technical solution adopted in the utility model is: slide plate reinforced seal device for a kind of novel grab bucket product, by bearing pin, being placed on the manganese cover of bearing pin and the revolving part being fixedly connected with manganese cover forms, it is characterized in that: manganese cover end seals by the axial plane of sealing member and bearing pin, described sealing member is by gland, slide plate and outside framework oil seal, packing ring forms, gland is placed on the end of manganese cover and is fixedly connected with revolving part, between gland and manganese cover end, be provided with successively the slide plate on cover and bearing pin, outside framework oil seal and packing ring, outside framework oil seal is fixedly connected with slide plate, slide plate radially slides along its end face with respect to manganese cover.
Described bearing pin is bucket body bearing pin, sheave shaft or strut axle, and corresponding, the revolving part on bearing pin corresponds to respectively as skip body, pulley and strut.
The utility model slide plate can move along its radial direction with respect to bearing pin, when rocking rotation, bearing pin can drive slide plate to slide up and down between gland and packing ring, because sliding surface is large, gap is little and be full of grease, water and dust cannot break through oil film and enter in manganese trepanning, meet the water proof and dust proof sealing effectiveness in large gap when bearing pin and cover wearing and tearing; Prevent that grease from leaking, it is stored in hole always, reduce the maintenance cost in using; When bearing pin radially rocks with respect to manganese trepanning, sealing member is difficult for damaged, has extended the service life of product.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.As shown in Figure 1, slide plate reinforced seal device for a kind of novel grab bucket product, by bucket body bearing pin 1, be placed on the manganese cover 2 of bucket body bearing pin and form with manganese cover 2 skip bodies that are fixedly connected with 3, manganese overlaps the axial plane of 2 ends by sealing member and bucket body bearing pin 1 and seals, described sealing member is by gland 5, slide plate 6 and outside framework oil seal 8, packing ring 7 forms, gland 5 is placed on the end of manganese cover 2 and is fixedly connected with skip body 3, gland 5 and manganese overlap the slide plate 6 being provided with successively between 2 ends on cover and bearing pin, outside framework oil seal 8 and packing ring 7, outside framework oil seal 8 is fixedly connected with slide plate 6, slide plate 6 radially slides along its end face with respect to manganese cover.When rocking rotation, bucket body bearing pin 1 can drive slide plate 6 to slide up and down between gland 5 and packing ring 7, because sliding surface is large, gap is little and be full of grease, water and dust cannot break through oil film and enter in manganese trepanning, meet the water proof and dust proof sealing effectiveness in large gap when axle and the wearing and tearing of manganese cover; Prevent that grease from leaking, it is stored in hole always, reduce the maintenance cost in using; When bearing pin radially rocks with respect to manganese trepanning, sealing member is difficult for damaged, has extended the service life of product.
On described skip body 3, be provided with the gland protection backing plate 4 being fixedly connected with it, gland protection backing plate 4 is placed on gland 5 peripheries, can play a protective role to gland 5.
In the above-described embodiments, the sealing member being formed by gland 5, slide plate 6, outside framework oil seal 8 and packing ring 7 sealing between the respectively connected manganese cover of sheave shaft, strut axle of product that is also applicable to grab bucket, bucket body bearing pin 1 is replaced by sheave shaft, strut axle accordingly, and skip body 3 is done corresponding replacement thereupon.
Only conduct is to explanation of the present utility model for above-mentioned embodiment, and the technical scheme that all employings are identical or equivalent technologies means obtain all belongs to the utility model claim protection domain.
