Abstract

The utility model relates to a kind of skip bucket tail rope hanger of fall arrest, and the bottom of 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 bottom surface of hollow steel cylinder top inner convex platform and the end face of flange leave 1-2 cm clearance; 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 is carried out in prompting; If when 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, and ensures mine safety production.

Description

A kind of skip bucket tail rope hanger of fall arrest
Technical field
The utility model relates to a kind of parts of mine hoist equipment, particularly a kind of skip bucket tail rope hanger of fall arrest.
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 falls.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of skip bucket tail rope hanger of fall arrest, can prevent tail rope from falling, and avoids mine hoisting accident occurs.
For solving the problems of the technologies described above, the technical solution of the utility model 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.
The beneficial effects of the utility model are:
1, the hollow steel cylinder that the utility model 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 periodic inspection hollow steel cylinder top inner convex platform and the end face of suspension rod flange, if be less than 1 centimetre, will start combined aural and visual alarm immediately, and safety inspection skip bucket tail rope hanger is carried out in prompting.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
embodiment 1as shown in Figure 1, 2: a kind of skip bucket tail rope hanger of fall arrest, comprise the suspension rod 2 hinged with connecting rod 1, suspension rod 2 is rotationally connected with bearing seat 4 by bearing and big nut 13, bearing seat 4 relies on longitudinal bolt 12 to be connected with the upper dish 5 rotating fork 6, rotate fork 6 hinged by cross bolts 14 and peach-shaped ring 7, a termination of steel wire tail rope 9 through and groove one around peach-shaped ring 7 enclose, adopt wire clips 8 to be fastenedly connected in the below of peach-shaped ring 7 and steel wire tail rope 9.The bottom of described suspension rod 2 is provided with the flange 3 be connected, and hollow steel cylinder 11 is inserted in from suspension rod 2 top, and the outer lug boss bottom hollow steel cylinder 11 is connected with upper dish 5 bolt rotating fork 6; The internal diameter of hollow steel cylinder 11 is greater than the flange 3 of suspension rod 2, and the internal diameter of hollow steel cylinder 11 top inner convex platform is less than the external diameter of flange 3, is greater than the external diameter of suspension rod cylinder 10; The bottom surface of hollow steel cylinder 11 top inner convex platform and the end face of flange 3 leave 1-2 cm clearance.
embodiment 2as shown in Figure 1, 2 :adopt the tail rope anti-drop method of the skip bucket tail rope hanger of a kind of fall arrest described in embodiment 1; Comprise
1. the bottom surface of hollow steel cylinder 11 top inner convex platform and the end face of flange 3 leave the gap of 1-2 centimetres, when suspension rod 2 with rotate the big nut 13 of numerous bolt of being connected of fork 6 or block bearing because of stripped thread or fracture failure, when falling together with pitching 6 with the rotation that hollow steel cylinder 11 connects, described gap will reduce;
2. in gig traction skip hoisting operation, Safety regulations stipulate: before daily work while inspection lifting means, also the gap of the bottom surface of hollow steel cylinder 11 top inner convex platform and the end face of suspension rod flange 3 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 11 top inner convex platform just hangs on the flange 3 of suspension rod 2, bears the weight of tail rope immediately, prevents tail rope from falling, and avoids mine hoisting accident occurs.
