Abstract
The invention relates to an anti-drop skip tail rope suspension device and an anti-drop method for a tail rope. An integrated flange is arranged at the bottom of a suspender, a hollow steel barrel sleeves from the top of the suspender, and an outer lug boss at the bottom of the hollow steel barrel is connected with an upper plate of a rotating fork by bolts; the inner diameter of the hollow steel barrel is larger than that of the flange of the suspender, and a 1 to 2 centimeters gap remains between the bottom of an inner lug boss of the top of the hollow steel barrel and the top of the flange; when the gap is reduced to less than 1 centimeter, a proximity switch installed for measuring the gap immediately starts an audible and visual alarm to remind people of performing safety inspection; if the gap is reduced to 0, the inner lug boss at the top of the hollow steel barrel is hung on the flange of the suspender to immediately bear the weight of the tail rope and prevent the tail rope dropping so as to avoid a mine hoisting accident and guarantee the mine safety production.

Background technology
In mine operation, usually adopt the ore of many rope friction gig traction skip hoisting down-holes, in order to the steel rope weight of balanced hoisting skip bucket, hang two steel wire tail ropes between generally bottom two skip buckets, with the steel rope weight of balanced hoisting skip bucket.Existing skip bucket tail rope hanger is under the repeated action of load duty, and Zeng attaching parts occurred and gets loose, and causes the safety misadventure that tail rope drops.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of skip bucket tail rope hanger and tail rope anti-drop method of fall arrest, can prevent tail rope from falling, avoid mine hoisting accident occurs.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of skip bucket tail rope hanger of fall arrest, comprise the suspension rod with rod hinge connection, suspension rod is rotationally connected by bearing and bearing seat, upper the coiling that bearing seat relies on longitudinal bolt and rotation to pitch is connected, rotate fork hinged by cross bolts and peach-shaped ring, a termination of steel wire tail rope is passed and groove one around peach-shaped ring encloses, and adopts wire clips to be fastenedly connected in the below of peach-shaped ring and steel wire tail rope; The bottom of described suspension rod is provided with the flange be connected, and hollow steel cylinder is inserted in from suspension rod top, and the upper valve snail that the outer lug boss bottom hollow steel cylinder and rotation are pitched ties and connects; The internal diameter of hollow steel cylinder is greater than the flange of suspension rod, and the internal diameter of hollow steel cylinder top inner convex platform is less than the external diameter of flange, is greater than the cylindrical external diameter of suspension rod; The bottom surface of hollow steel cylinder top inner convex platform and the end face of flange leave gap, and hollow steel cylinder can rotate with rotation fork.The gap that the bottom surface of described hollow steel cylinder top inner convex platform and the end face of flange leave is 1-2 centimetres.
Adopt the tail rope anti-drop method of the skip bucket tail rope hanger of above-mentioned a kind of fall arrest; Comprise
1. the bottom surface of hollow steel cylinder top inner convex platform and the end face of flange leave the gap of 1-2 centimetres, when suspension rod and rotation pitch the big nut of numerous bolt or the block bearing be connected because of stripped thread or fracture failure, when falling together with pitching with the rotation that hollow steel cylinder connects, described gap will reduce;
2. in gig traction skip hoisting operation, Safety regulations stipulate: before daily work while inspection lifting means, also the bottom surface of hollow steel cylinder top inner convex platform and the gap of suspension rod flange top surface will be checked, if described gap drops to when being less than 1 centimetre, the proximity switch installed for measurement clearance starts combined aural and visual alarm immediately, and safety inspection skip bucket tail rope hanger is carried out in prompting;
If when 3. described gap is kept to zero, hollow steel cylinder top inner convex platform just hangs on the flange of suspension rod, bears the weight of tail rope immediately, prevents tail rope from falling, and avoids mine hoisting accident occurs.
The invention has the beneficial effects as follows:
1, the hollow steel cylinder that the present invention increases newly is the protecting sleeve that defence skip bucket tail rope falls,
When suspension rod and rotation pitch the big nut of numerous bolt or the block bearing be connected because of stripped thread or fracture failure, when falling together with pitching with the rotation that hollow steel cylinder connects, hollow steel cylinder top inner convex platform hangs on the flange of suspension rod, bear the weight of tail rope immediately, prevent tail rope from falling, avoid mine hoisting accident occurs, ensure mine safety production.
2, in ongoing operations runs, the gap of the bottom surface of routine observation hollow steel cylinder top inner convex platform and the end face of suspension rod flange, if be less than 1 centimetre, will check skip bucket tail rope hanger comprehensively.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
