Description
Technical field
The present invention relates to the parts of a kind of mine hoist equipment, the skip bucket tail rope hanger of a kind of fall arrest and
Tail rope anti-drop method.
Background technology
In mine operation, generally use the Ore of many rope friction elevator traction skip hoisting down-holes, carry to balance
Rise skip bucket steel wire rope weight, typically bottom two skip buckets between hang two steel wire tail ropes, with the steel of balanced hoisting skip bucket
Cord weight.Existing skip bucket tail rope hanger, under the repeated action of load duty, occurred connector to get loose, caused
The security incident that tail rope drops.
Summary of the invention
The technical problem to be solved in the present invention is to provide skip bucket tail rope hanger and the anti-fall side of tail rope of a kind of fall arrest
Method, can prevent tail rope from falling, avoid mine hoisting accident.
For solving above-mentioned technical problem, the technical scheme is that the skip bucket tail rope hanger of a kind of fall arrest, bag
Including the suspension rod with rod hinge connection, suspension rod is rotationally connected with bearing block by bearing, and bearing block relies on longitudinal bolt and rotates fork
Upper dish connects, and rotates fork hinged with peach-shaped ring by cross bolts, and a termination of steel wire tail rope is through and around peach-shaped ring
Groove one encloses, and uses wire clips to be fastenedly connected in the lower section of peach-shaped ring with steel wire tail rope；The bottom of described suspension rod is provided with and is connected
Flange, hollow steel cylinder is inserted in from suspension rod top, the outer lug boss bottom hollow steel cylinder and rotate the upper valve snail of fork and tether and connect；Hollow
The internal diameter of steel cylinder is more 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, more than suspension rod cylinder
The external diameter of body；The bottom surface of hollow steel cylinder top inner convex platform and the end face of flange leave gap, and hollow steel cylinder can be with rotating fork
Rotate.The gap that the bottom surface of described hollow steel cylinder top inner convex platform and the end face of flange leave is 12 centimetres.
Use the tail rope anti-drop method of the skip bucket tail rope hanger of above-mentioned a kind of fall arrest；Including
1. the bottom surface of hollow steel cylinder top inner convex platform and the end face of flange leave the gap of 12 centimetres, when suspension rod with turn
Numerous bolts of moving fork connection or the big nut of block bearing are because of stripped thread or fracture failure, the rotation being connected with hollow steel cylinder fork one
When rising, described gap will reduce；
2. in elevator traction skip hoisting operation, safety code specifies: checking lifting means before daily work
Meanwhile, the bottom surface of hollow steel cylinder top to be checked inner convex platform and the gap of suspension rod flange top surface, if described gap drops to
During less than 1 centimetre, the proximity switch installed by measuring gap starts audible-visual annunciator immediately, and prompting carries out safety inspection skip bucket
Tail rope hanger；
If the most described gap is kept to zero, hollow steel cylinder top inner convex platform just hangs on the flange of suspension rod, undertakes immediately
The weight of tail rope, prevents tail rope from falling, it is to avoid 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 protection set that defence skip bucket tail rope falls,
When suspension rod with the big nut rotating numerous bolts of being connected of fork or block bearing because of stripped thread or fracture failure, with hollow
When the rotation fork that steel cylinder connects falls together, hollow steel cylinder top inner convex platform hangs on the flange of suspension rod, undertakes tail rope immediately
Weight, prevents tail rope from falling, it is to avoid mine hoisting accident occurs, and ensures mine safety production.
2, in ongoing operations runs, the bottom surface of routine observation hollow steel cylinder top inner convex platform and the end face of suspension rod flange
Gap, if less than 1 centimetre it is necessary to check skip bucket tail rope hanger comprehensively.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
