Description
Technical field
The utility model relates to a kind of strong or coventional type travelling apron and implement the device of arresting behind the adhesive tape broken belt, relates in particular to high spud angle, large conveying quantity, long apart from going up a hill (up) of carrying of colliery inclined shaft or (descending) belt conveyer of going down the hill is arrested device with broken belt.
Background technology
Present broken belt catching device is divided into two kinds of versions: a kind of is that Purely mechanical has eccentric wheel and trigger mechanism; Another kind of for having the electric liquid drawing type of broken belt acquisition of signal.The broken belt catching device handling characteristics of these two kinds of versions: be installed on the frame of conveyer, behind the adhesive tape broken belt, braking implemented to arrest in its both sides, stop adhesive tape to glide, play the safety guard-safeguard effect.Its stop mechanism is formed by supporting carrying roller, cam or parts such as eccentric wheel, crank and brake shoe.When oppositely downslide drives the contrarotation of support carrying roller behind the adhesive tape broken belt, trigger crank and brake shoe and rotate to braking position, brake the adhesive tape that clamps downslide by the mode that cam or eccentric wheel are pressed to brake shoe with adhesive tape.Its advantage is simple in structure, is easy to make, and cost is low.Weak point is: contact for the line face with the contact surface of load-transfer device, contact surface is little, and its friction brake force is little.Arrange 1 for per 20～30 meters along the line, left-right symmetric is installed, make owing to exist, practical problemss such as installation, a large amount of catching devices are installed are guaranteed its synchronous working, so, in case travelling apron broken belt, catching device implements to arrest glancing impact, owing to be subjected to the effect of adhesive tape enormous impact power, that devotes oneself to work earlier arrests device because friction brake force is little, be difficult to slow down the falling tendency of adhesive tape to a great extent, damaged by the huge inertia impact of adhesive tape even, the follow-up machine of arresting of devoting oneself to work since braking force limited, and the seismic inertia of adhesive tape in time continuity and increase severely, arrest braking failure, thereby cause the catching device of all installations to lose due safety guard-safeguard effect; Purely mechanical and electric liquid drawing type broken belt catching device are installed in the adhesive tape both sides of the edge, the line contact easily produces adhesive tape and shears and the damage load-transfer device, if arresting braking very likely tears it (this situation just appears in coal, flat coal and Zheng's coal subordinate's of group coal mine user forever) when effective, there is not steel cable core intensity difference as the steel cable belt both sides, various broken belt catching device recited above is being arrested glancing impact, and application force all is applied to the adhesive tape both sides; When rubber belt from deviating, arrest braking failure, often produce friction, the damage adhesive tape with adhesive tape.In addition, present electric liquid drawing type and the Purely mechanical broken belt catching device that uses, control simple and easy or do not have control, cause mistake braking easily, as when the belt conveyer orderly closedown, though holdback or drg are installed, but a segment distance also can glide under the effect of gravity, just can cause the mistake braking, be easy to damage equipment, cause the accident when serious; From the constructional feature of itself, the functional reliability of this type of broken belt catching device is difficult to guarantee, adhesive tape and material during broken belt are owing to be subjected to the effect of gravity, and the speed of downslide is more and more faster, and the broken belt head is done the great-jump-forward random motion, its inertial impact force is very huge, because this type of device is mounted on the frame of belt conveyer, implement to arrest glancing impact, if arrest effectively, often possible torsional deflection, it is badly damaged that very the person causes the conveyer frame.Therefore, popularization face is very limited.
