Abstract
The invention discloses a lower broken belt protector for a belt conveyor, which belongs to a conveyor protector and comprises an oil cylinder, a connecting pin, a connecting seat, a bearing seat, a transmission seat assembly and an upper pressing shaft. The connecting seat, the bearing seat and the transmission seat assembly are mounted on the upper pressing shaft; the front end of the oil cylinder is connected with the connecting seat through the connecting pin, and the connecting seat is connected with the upper pressing shaft through keys and can rotate along the center of the bearing seat. The lower broken belt protector for the belt conveyor further comprises a lower pressing shaft on which a lower transmission seat assembly and a lower pressing block are mounted; and the transmission seat assembly is connected with the lower transmission seat assembly through a connecting bar. The invention has the advantages of large catching contact surface, large catching force, no damage on a belt, convenient catching of plat type or V-shaped lower belts with the catching travel distance reaching to 400 millimeters compared with the traditional broken belt catchers.
Description
Technical field
The present invention relates to a kind of belt break protection device.Specifically be belt break protection device under a kind of belt conveyer, be particularly suitable on belt conveyer, using.
Background technology
Show that according to market research belt conveyer is widely used in numerous areas such as mine, metallurgy, chemical industry, light industry, coal, harbour.Past, because the fed distance of belt conveyer is long, operating environment was abominable mainly by the hand inspection adhesive tape, and it is very inconvenient to overhaul.Especially on the high spud angle conveyer, the broken belt accident takes place all can bring fatal crass's tragedy basically, country and enterprise are sustained a great loss, people's lives come to harm; National security production supervision Public Roads Administration, national safety of coal mines supervision Supervisory Bureau, Chinese coal association of industries be regulation in " safety regulations in coal mine " the 375 and " safety of coal mines quality standardization standard and examination grading way " (trying) mechanical and electrical safety grading especially: the Steel cord belt conveyer should be provided with belt break protection device.
In recent years, the broken belt that has occurred on the market is arrested device, summarize the structural shape that its stop mechanism is made up of cam, eccentric wheel, crank etc. mostly, at the adhesive tape that carries out glancing impact clamping downslide is the line contact, braking force is little, reliability is not high, and the isochrone contact easily produces the adhesive tape both sides of the edge and shears and the damage adhesive tape, when serious adhesive tape is torn; When rubber belt from deviating, often produce the frictionally damage adhesive tape with adhesive tape; Easily cause stifled carrying; Cause the mistake braking easily; such as moment when the belt conveyer orderly closedown; adhesive tape stops after leaning on the inertia continuation up; though holdback or drg are installed; but the segment distance that also can glide under the effect of gravity just can cause the mistake braking, is easy to damage equipment; cause the accident when serious, thereby popularization face is very limited.
Summary of the invention
For overcoming the above-mentioned drawback of prior art, the invention provides belt break protection device under a kind of belt conveyer,
The present invention realizes with following technical scheme: belt break protection device under a kind of belt conveyer comprises oil cylinder, connecting pin, Connection Block, bearing seat, retainer assembly and upper pressure axial; Connection Block, bearing seat and retainer assembly are installed on the upper pressure axial, and the front end of oil cylinder links together by connecting pin and Connection Block, and Connection Block is connected with key with upper pressure axial and can rotates along the bearing seat center; Also comprise last item down, on the last item underdrive seat assembly and lower lock block are being installed down; The retainer assembly is connected with the underdrive seat assembly by connecting rod.
Upper pressure axial is driving retainer assembly, connecting rod, following last item, lower lock block rotation and will descend load-transfer device to push down on lower platen when rotating under the drive of oil cylinder.
The invention has the beneficial effects as follows: compare with existing broken belt catching device, it is big to have a contact surface of arresting, and the power of arresting is big, does not damage belt, arrests stroke and is 400 millimeters, can arrest flat pattern or V-type hypodermis band easily.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
