Abstract
The utility model relates to a maintenance tool for a coal mine underground large-scale steel wire rope core strong force belt conveyor, in particular to a roller bearing fast dismounting and mounting tool for a mine. The problem of in-site hot bearing dismounting and mounting incapability during the underground roller replacement is solved. The roller bearing fast dismounting and mounting tool for the mine comprises a dismounting tool and a mounting tool, wherein the dismounting tool comprises a plurality of pull rods, one ends of the pull rods are arranged in screw holes of a bearing seat, the other ends of the pull rods are fixedly connected with a pull plate, a jack is arranged between the pull plate and the bearing seat, the mounting tool comprises a plurality of groups of clamp hooks clamped at the two sides of the outer wall of a roller, the number of the clamp hooks in each group is two, a double-head screw rod is arranged between each group of clamp hooks in a penetrating way, one end of the double-head screw rod is fixedly connected with a steam beam through double screw nuts, and a jack is arranged between a steel beam and the bearing seat arranged on the outer wall of the roller. The roller bearing fast dismounting and mounting tool for the mine is a special dismounting and mounting tool used for dismounting and mounting belt conveyor roller bearings, the replacement is simple and convenient, and in addition, the in-site hot dismounting and mounting is not needed.
Description
Technical field
The utility model relates to large-scale Steel cord powerful belt conveyor maintenance tool under coal mine, specifically a kind of mining roller bearings Quick disassembling tool.
Background technology
The underground coal transportation in colliery adopts large-scale Steel cord powerful belt conveyor, the formation of every sealing-tape machine comprises various transmissions, the bend pulley of 10 left and right, the diameter of cylinder is 1 meter of left and right, weight is more than 4 tons, the self-aligning bearing external diameter adopting is all half meter of left and right, between bearing and axle and bearing and bearing block (integral body, the non-formula of cuing open), all adopt hot charging interference fit.Due to reasons such as aging, abnormal load, mass discrepancies, the bearing of cylinder there will be the faults such as roller wearing and tearing, retainer and inner-outer sleeve fracture, causes the stopping accident of sealing-tape machine.Because the general instruments such as horse that draw can not use at the scene, the way in the past adopting is replacing cylinder or on-the-spot hot dismounting bearing, but because the environment at scene, down-hole is severe, narrow space, has problems, changes very difficulty, difficult quality guarantee.And along with the further raising of mine gas management expectancy, more and more lower for the tolerance of down-hole work with torches, be not even allowed to, so on-the-spot hot dismounting process will be eliminated.
Summary of the invention
The utility model changes in order to solve down-hole the problem that cylinder cannot on-the-spot hot dismounting bearing, and a kind of mining roller bearings Quick disassembling tool is provided especially.
In order to address the above problem, the utility model is taked following technical scheme: a kind of mining roller bearings Quick disassembling tool, comprise extracting tool and erecting tools, described extracting tool comprises that some one end are arranged on pull bar in bearing block screw, the pull bar other end is fixedly connected with arm-tie, between arm-tie and bearing block, is provided with jack; Described erecting tools comprises the some groups of snap fits that are stuck in the both sides of cylinder outer wall, every group of snap fit is 2, between every group of snap fit, be equipped with double threaded screw, double threaded screw one end is fixedly connected with girder steel by double nut, between girder steel and the bearing block of cylinder outer wall, is provided with jack.
The pull bar of extracting tool has 6.
Bearing Quick disassembling tool using method is as follows:
Dismounting:
Sling with chain block in cylinder two ends, remove bad bearing end set bolt, the other end unclamps bolt slightly, then with chain block is oblique, the bad bearing end of cylinder is hung to large frame 100mm left and right, uses construction; With a little chain block, hang bad bearing block of position;
First remove bearing outer end cap, pull bar and arm-tie are assembled, spindle nose is withstood with 50 tons of jack in centre, slowly bearing is pulled out together with bearing block, separated with axle; Then land;
Remove bearing block rear pressing cover bolt, with jack, withstand bearing, slowly that bearing is separated with bearing block.
Install:
Clean complete, rear pressing cover is installed;
New bearing, to good, is withstood between arm-tie and bearing with jack, bearing is slowly pressed in seat;
Bearing block integral body is sling, and bearing and axle are to good;
Install pull bar and girder steel, with jack, withstand between girder steel and bearing inner sleeve, slowly bearing is compressed on axle; According to actual conditions, if the tension that coordinates of bearing and axle is pressed into difficulty, available cutter adds thermal expansion slightly to inner sleeve;
Cylinder is recovered to be in place, Leveling and centering; Bearing is clean to refuel, and recovers outer end cap.
Compared with prior art, the beneficial effects of the utility model are: use special-purpose dismantling device to carry out dismounting to sealing-tape machine roller bearings, change easyly, and do not need on-the-spot hot dismounting.
