Description
Technical field
The utility model relates to the rotary drilling rig that uses in a kind of engineering construction, particularly a kind of elevator rope processing device that is used on the rotary drilling rig.
Background technology
Rotary drilling rig is the efficient pore-forming equipment of heavy caliber that uses in a kind of foundation construction, and the drilling rod that its utilization remains vertical direction directly rotates, excavates ground, thereby forms the stake hole of the required diameter and the degree of depth fast on ground.This rotary drilling rig since power big, power is strong, easy to use, pore-forming is quick, so in the foundation construction process of the engineering of being widely used in, building.Existing is that the assurance steel rope is pressed the tactic rope processing device of layer on the elevator cylinder, can be divided into off-axis formula rope processing device and logical pinch roller formula rope processing device, it is bigger owing to two arm-tie intermediate distances when steel rope is gone to elevator cylinder two ends, cause the two ends discontinuity equalization, one end spring seriously stretches, and an end does not stress or be stressed very little, causes spring failure, thereby cause steel rope chaotic winding on cylinder, influence drilling rod and transfer smoothly and promote; Simultaneously, the pinch roller inner shaft bears axial load and increases, and damages easily, thereby makes pinch roller rotate dumb even can not rotate, and causes steel rope direct friction on pinch roller, shortens steel rope service life.
The utility model content
The utility model is to provide a kind of safe and reliable elevator rope processing device that is used on the rotary drilling rig, to solve shortcoming in the above-mentioned background technology with not enough.
The technical matters that the utility model solved realizes by the following technical solutions:
A kind of elevator rope processing device that is used on the rotary drilling rig, pinch roller in the middle of comprising, left side awl pinch roller, right awl pinch roller, wheel pressing shaft, the spring pulling shaft, pull bar, link span, antifriction-bearing box, spacer, axle sleeve, it is characterized in that, pinch roller and left side awl pinch roller in the middle of two pull bars place respectively, and between the right awl pinch roller, original whole section pinch roller is divided into middle pinch roller, left side awl pinch roller, three sections of right awl pinch rollers, thereby shortened the support distances of two pull bars between wheel pressing shaft, three sections suffered moments of torsion of each section of wheel pressing shaft and perk degree are all reduced greatly, thereby reduced the friction force of steel rope, improved the service life of steel rope.
In the utility model, described left side awl pinch roller, right awl pinch roller all adopt the little round platform pattern broad in the middle in outer end.When steel rope walked to the left and right two ends of cylinder, left and right awl pinch roller diameter reduced, thereby has reduced wheel pressing shaft perk degree, the service life of having improved steel rope.
In the utility model, described left side awl pinch roller, right awl pinch roller endoporus are respectively arranged with a pair of antifriction-bearing box, when steel rope walks to the left and right two ends of cylinder, form the rolling fulcrum by antifriction-bearing box, all the other two sections pinch rollers do not rotate, thereby reduced the moment of flexure of carrying on wheel pressing shaft and the bearing, it is more flexible to make that pinch roller rotates, steadily, make steel rope on cylinder, twine one deck simultaneously, the bearing number of revolutions is finished by former pair of bearings, and become three pairs of bearings and finish respectively, thus the service life of having improved bearing period of service and rope processing device.
Beneficial effect: the utility model passes through to shorten the distance of two pull bars between wheel pressing shaft, and increases by two width of cloth antifriction-bearing boxs, makes rope processing device can guarantee that in the course of the work steel rope is neat by layer serial arrangement, has increased the service life of rope processing device and steel rope again.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete accompanying drawing, further set forth the utility model:
Referring to Fig. 1, shown in Figure 2, a kind of elevator rope processing device that is used on the rotary drilling rig comprises nut (1,10), spring washer 2, packing ring (3,6), spring stop 4, bolt 5, spring pulling shaft 7, spring 8, link span 9, right awl pinch roller 11, back-up ring (12,13,15,19), bearing (14,18), wheel pressing shaft 16, pinch roller 17, spacer 20, pull bar 21, axle sleeve 22, left side awl pinch roller 23.By pinch roller in the middle of two pull bars 21 are placed respectively 17 and right awl pinch roller 11, and left side awl pinch roller 23 in the middle of, thereby when shortening steel rope and walking to the cylinder end and the distance of two pull bars, reduce wheel pressing shaft perk degree, reduce steel rope abrasion, improve steel rope service life; Left side awl pinch roller 23, right awl pinch roller 11 all adopt the little round platform pattern broad in the middle in outer end, and when steel rope walked to the left and right two ends of cylinder, left and right awl pinch roller diameter reduced, thereby had reduced the perk degree of wheel pressing shaft 16, the service life of having improved steel rope; Two pairs of antifriction-bearing boxs 14 are installed in respectively on right side awl pinch roller 11, the left side awl pinch roller 23, by back-up ring 12,13,15,19, reach spacer 20, axle sleeve 22 and accurately locate on wheel pressing shaft.When steel rope walked to a left side (right side) pinch roller, all the other two pinch rollers did not rotate, and finished thereby rotated by former pair of bearings when steel rope is arranged one deck on cylinder, became three pairs of bearings and finished, and improved the bearing period of service thus, thereby improved the service life of rope processing device.Spring pulling shaft 7 passes the pull bar 21 on left and right both sides, and by nut 1, spring washer 2, packing ring 3 make pull bar 21 location on left and right both sides.Pull bar 21 is fixed on the elevator frame by the hinged seat on bearing pin and the elevator frame.Link span 9 passes the spring dead plate on the elevator frame, makes the spring initial tensile force suitable by adjustment nut 10.When the steel rope number of plies changes, by spring force pinch roller is pressed on steel rope on the cylinder, avoid the disorder cable phenomenon to take place.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
