Description
Technical field
The present invention relates to the belt transportation art, be specifically related to a kind of belt conveyer broken belt limiting protector.
Background technology
Belt conveyer is a kind of major equipment of carrying bulk material, because it is big that it has traffic capacity, simple in structure, investment cost is relatively low, and characteristics such as easy to maintenance and be widely used in industry transported materials such as mine, harbour, harbour, metallurgy, thermoelectric power station, chemical plant.Especially use more extensive in the colliery, belt conveyer is installed in mostly in the colliery that the inclination angle, tunnel is big, and transportation range is long, the main fortune tunnel in the fortune coal quantity set, undertaking the Coal Transport task of one or several exploiting field even full mine, is the maincenter of mine Coal Transport system.Belt conveyer particularly has the belt conveyer at inclination angle at convey materials (hectare angular region is between 6～25 °), for preventing that slipping of the belt from needing belt tension, the tensile force that belt is long more, freight volume is big more, the big more belt in hectare angle is required is big more, in the belt operational process if broken belt takes place, add the material carried on the belt and the screen resilience of belt, broken belt will cause very big secondary destructive effect after taking place, and be catastrophic sometimes.
For preventing the secondary destructive effect after broken belt generation and broken belt take place; there are various broken belt detecting devices and broken belt catching device on band hectare angle belt conveyer, to use; its principle of mode of clamping conveying belt is basic identical during singly from broken belt; all be when the generation band is disconnected; load-transfer device drops to zero fast by normal speed; begin then to lower slider, belt break protection device also begins braking.From carrying out the mechanism that clamps action, mainly contain friction ratchet gear formula mechanism roller squash type structure, roller squash type structure etc.Disclose among the patent documentation CN 101148222A a kind of can central controlled wedge type belt type conveyer broken-belt protecting device; A kind of travelling apron belt break protection device of being made up of multiple sensors and complex mechanical structure is disclosed among the CN 201372115Y.More above-mentioned belt break protection devices are being grabbed belt after in time finding broken belt hidden danger and broken belt and are being avoided playing a role of secondary destruction, yet because broken belt is incident, add the working environment complexity under the coal mine, the tunnel humidity, some broken belt catching device is failure to actuate for a long time, and is of long duration, and catching device is malfunctioning when broken belt takes place unavoidably, in the practical application in colliery, the malfunctioning phenomenon of catching device happens occasionally when the belt broken belt; Also have some belt break protection devices to make difficulty comparatively speaking, complex structure, poor reliability, and also the human and material resources that care and maintenance drops into are bigger.
