Abstract
The utility model discloses a belt conveyor lower broken belt protection device, which belongs to conveyor protection devices and comprises an oil cylinder, a connecting pin, a connecting seat, a bearing block, a transmission seat assembly and an upper pressure shaft. The connecting seat, the bearing block and the transmission seat assembly are mounted on the upper pressure shaft, the front end of the oil cylinder is connected with the connecting seat through the connecting pin, and the connecting seat and the upper pressure shaft are connected via keys and can rotate along the center of the bearing block. The protection device further comprises a lower pressure shaft, a lower transmission seat assembly and a lower pressure block are mounted on the lower pressure shaft, and the transmission seat assembly is connected with the lower transmission seat assembly through a connecting rod. Compared with existing broken belt catchers, the belt conveyor lower broken belt protection device has the advantages of large catching contact area, large catching force, no belt damage, catching stroke up to 400 millimeters, and capability of conveniently catching lower flat belts or V-belts.
Description
Technical field
The utility model 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 utility model provides belt break protection device under a kind of belt conveyer,
The utility model is realized 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 beneficial effects of the utility model are: 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
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model deployed configuration scheme drawing.
Among the figure: 1, oil cylinder, 2, connecting pin, 3, Connection Block, 4, bearing seat, 5, upper pressure axial, 6, the retainer assembly, 7, connecting rod, 8, last item down, 9, flat key, 10, axle sleeve, 11, lower lock block, 12, lower platen, 13, load-transfer device, 14, the underdrive seat assembly.
The specific embodiment
As depicted in figs. 1 and 2, device of the present utility model is by forming as the lower part: oil cylinder 1, connecting pin 2, Connection Block 3, bearing seat 4, upper pressure axial 5, retainer assembly 6, underdrive seat assembly 14, connecting rod 7, following last item 8, flat key 9, axle sleeve 10 and lower lock block 11.Connection Block 3, bearing seat 4 and retainer assembly 6 are installed on the upper pressure axial 5.Oil cylinder 1 front end links together by connecting pin 2 and Connection Block 3, and Connection Block 3 usefulness keys are connected on the upper pressure axial 5, and it is rotated along bearing seat 4 centers.Retainer assembly 6 is connected with underdrive seat assembly 14 by connecting rod 7, and underdrive seat assembly and lower lock block 11 are installed in down on the last item 8, and two retainer assemblies 6 adopt bearing pin to be connected with connecting rod 7.Described lower lock block 11 adopts axle sleeve 10 to be installed in down on the last item 8, and following last item 8 adopts flat key 9 to be connected with axle sleeve 10.Upper pressure axial 5 will descend load-transfer device 13 to push down on lower platen 12 drive retainer assembly 6, connecting rod 7, last item 8, lower lock block 11 rotations down under the drive of oil cylinder 1 when rotating.
