Abstract
The utility model relates to a swing span for trolley -bus scraper, including corresponding two bearing retainer (, be connected with two corresponding bearing plate between two bearing retainer, bearing plate's middle part is equipped with the circular port, the outside rigid coupling of bearing plate circular port have with the endocentric supporting shaft sleeve of circular port, the cover is equipped with the copper sheathing rather than interference fit on supporting shaft sleeve's the external diameter. The utility model discloses the design of swing span configuration optimization, the mechanism is simple, reasonable. In can realizing, the application of small -size trolley -bus scraper double bracing swing span, have very strong practicality.
Description
Technical field
the utility model belongs to mechanical field, relates to the trackless scraper for underground mining, is specifically related to a kind of swing span for trackless scraper.
Background technology
swing span at present on middle-size and small-size trackless scraper, due to scraper Rear frame space structures closely, there is no enough installing spaces, scraper swing span is designed to single support pattern, single swing span fore-stock axle place stress that supports is concentrated, discontinuity equalization, sometimes the longitudinal bore in Rear frame also can be caused to damage, even there will be phenomenon of rupture at cylinder step transition place, affect car load to use, cause equipment dependability to decline, service efficiency is low, maintenance cost increases, and have impact on normal production.
Utility model content
in order to solve the problems referred to above that prior art exists, the utility model provides a kind of swing span for trackless scraper.
the technical scheme that the utility model adopts is: a kind of swing span for trackless scraper, comprise corresponding two bearings support, corresponding diaxon board is connected with between two bearings support, the middle part of shaft bearing plate is provided with circular port, the outside of shaft bearing plate circular port is connected with the support sleeve concentric with circular port, the external diameter of support sleeve is set with the copper sheathing with its interference fit.
further, shaft bearing plate is docked by upper bearing (metal) plate and lower shaft board and forms, the two ends of upper bearing (metal) plate connect with corresponding two bearings support, and the middle part of upper and lower shaft bearing plate joint has concentric semicircles, the circular port described in the two semicircular docking on upper and lower shaft bearing plate is formed.
further, the butt end of upper and lower shaft bearing plate is provided with the positioning step cooperatively interacted.
further, be connected from the bolt that circumferentially penetrates of support sleeve outer face with shaft bearing plate.
the beneficial effects of the utility model: the utility model is simple and reasonable for structure, uniform force, stable working, the installing space saved on car body, the problem that both can solve insufficient space and the difficulty installed, the smooth operation of machine can be ensured again simultaneously, be applicable to the medium and small underground trackless scraper of compact conformation, there is very strong practicality.

Detailed description of the invention
a kind of swing span for trackless scraper, swing span comprises forward and backward corresponding two bearings support 1, support sleeve 3, copper sheathing 5, all shaft bearing plate is connected with between forward and backward corresponding two bearings support 1 left end and between forward and backward corresponding two bearings support 1 right-hand member, diaxon board is mutually corresponding, the middle part of shaft bearing plate is provided with circular port 11, the outside of shaft bearing plate circular port 11 is connected with the support sleeve 3 concentric with circular port, is connected from the bolt 7 that circumferentially penetrates of support sleeve 3 outer face with shaft bearing plate.The external diameter of support sleeve 3 is set with the copper sheathing 5 with its interference fit.Further, the shaft bearing plate of swing span left end and the shaft bearing plate of swing span right-hand member divide equally upper and lower two parts, composition is docked by upper bearing (metal) plate 8 and lower shaft board 6, the middle part of upper and lower shaft bearing plate joint has concentric semicircles, circular port 11 described in two semicircular docking on upper and lower shaft bearing plate is formed, the butt end of upper and lower shaft bearing plate is provided with the positioning step cooperatively interacted.
copper sheathing 5 external diameter and scraper aftercarriage installation place matched in clearance, swing span is coordinated with Rear frame by copper sheathing 5 outer radius at two ends to be installed, drive axle is arranged on the below of the support of bearing 1 with back axle installing plate 2 by suspension bridge bolt 10, the two ends of lower shaft board 6 bottom are connected with back axle installing plate 2 by bolt, swing span is then be arranged in the Rear frame of trackless scraper by articulated manner, swing span can make reciprocally swinging according to the longitudinal centre line of scraper, swing span ensure that the opposing oscillatory of scraper under steam between front/rear frame, thus alleviate jolting and impacting when travelling on uneven road surface suffered by vehicle bridge, realize four-wheel before and after scraper to land simultaneously.
the utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
