Abstract

A wearing-resisting roller device provided with an anti-falling safety rope comprises lug plates arranged on two sides and a rolling bar mounted between the lug plates, wherein the safety rope axially and transversely penetrates through the middle of the rolling bar; and after two ends of the safety rope penetrate through rear rope head parts of the lug plates respectively, rope head parts are pressed by pressing joints into a ring shape and are added with lantern rings. The wearing-resisting roller device provided with the anti-falling safety rope is simple in structure and convenient to use, the safety rope is added in the middle of the rolling bar of the wearing-resisting roller device, the two ends of the safety rope are connected onto the lug plates or D-shaped rings on the main body through engineering shackles during use, so that when the rolling bar is broken, the safety rope can prevent the rolling bar from falling off, and accordingly, the safe anti-falling function is achieved.

Description

With the abrasionproof roller devices of safe fall-proof rope

Technical field

The utility model relates to oil-well rig field, particularly a kind of abrasionproof roller devices with safe fall-proof rope.

Background technology

The abrasionproof roller devices that at present oil-well rig uses comprises that both sides install otic placode and be arranged on the rolling bar of the rotation between otic placode, and when rolling bar ruptures during in operation, rolling bar falls and easily causes security incident, and the person and property are damaged.

Summary of the invention

In order to eliminate because of the rolling bar potential safety hazard of falling and causing that ruptures, the invention provides a kind of abrasionproof roller devices with safe fall-proof rope of simple in structure, reasonable in design and safety and stability.

The technical solution of the utility model is: comprise otic placode that both sides arrange with and be arranged on the rolling bar between otic placode; Described rolling bar jackshaft is to crossing safety rope, and the two ends of described safety rope adopt compacting joint to be pressed into ring-type and to install the collar additional through fag end part after otic placode respectively.

Such scheme can further be improved to:

On the described collar, be flexibly connected engineering shackle.

Described compacting joint is preferably aluminium alloys compacting joint.

Described safety rope is preferably wire rope

The utility model is simple in structure, easy to use, by install safety rope additional in the middle of rolling bar at abrasionproof roller devices, when use, safety rope two ends are connected on the otic placode or D type ring in main body by engineering shackle, in the time there is fracture in rolling bar, safety rope can prevent that rolling bar from falling, and plays thus the effect of safe anti-falling.

Detailed description of the invention

With reference to Fig. 1-2, a kind of abrasionproof roller devices with safe fall-proof rope, comprise otic placode 1 that both sides arrange with and be arranged on the rolling bar 2 between otic placode 1; Rolling bar 2 jackshafts are to crossing safety rope 3, and safety rope 3 adopts petroleum gas industrial wire rope 5; The two ends of safety rope 3 adopt aluminium alloys compacting joint 6 to be pressed into ring-type and to install the collar 7 additional through the rear fag end part of otic placode 1 respectively, are flexibly connected engineering shackle 4 on the collar 7.

When use, safety rope two ends are connected on the otic placode or D type ring on drill main body by engineering shackle, and in the time that fracture occurs rolling bar, safety rope can prevent that rolling bar from falling, and plays thus the effect of safe anti-falling.
