Description
Technical Field
The utility model relates to an equipment maintenance tool, in particular to a folding type coupler disassembling tool.
Background
The most difficult task during the disassembly of the coupling is to remove the hub from the shaft. For keyed hubs, disassembly is typically performed using a three-legged puller or a four-legged puller. Because the outer end of the puller is in point contact with the cross section of the coupler, the slippage is easy to occur when the stress is uneven. Not only causes abrasion to the end face of the coupler, but also is easy to cause safety accidents. And in addition, the manual tightening by using threads consumes time and labor and has low efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the technical problems and overcomes the defects of the prior art, and provides a hinge type coupler disassembling tool which comprises a left tensile frame, a right tensile frame, a left shaft sleeve, a right shaft sleeve, a connecting bolt and a locking nut, wherein the left shaft sleeve comprises a plurality of shaft sleeve units and is uniformly distributed on one edge of the left tensile frame, the right shaft sleeve comprises a plurality of shaft sleeve units and is uniformly distributed on one edge of the right tensile frame, the left shaft sleeve and the right shaft sleeve are mutually nested at intervals, the left tensile frame and the right tensile frame form a hinge type structure, the connecting bolt is inserted into the left shaft sleeve and the right shaft sleeve, and the tail end of the connecting bolt is fixed by screwing the nut.
The utility model further defines the technical scheme that:
the hinge type shaft coupling disassembling tool comprises a shaft sleeve unit close to the top end of a connecting bolt and a shaft sleeve unit close to a screwing nut, wherein the shaft sleeve units belong to the same tensile frame.
The folding type shaft coupler dismounting tool comprises a left shaft sleeve and a right shaft sleeve, wherein the left shaft sleeve comprises four shaft sleeve units, and the right shaft sleeve comprises five shaft sleeve units.
The thickness of the left tensile frame and the right tensile frame is 20 +/-0.5 mm.
The length of the part below the long top end of the connecting bolt is 3700 +/-0.5 mm.
The utility model has the beneficial effects that:
(1) the utility model solves the problems of heavy weight, time consumption and labor consumption of the old type puller, and meanwhile, the dismounting tool can increase the stress area of force and change the original three-point contact into the current 2-line symmetrical stress, so that the stress area is increased and uniform, the safety and the reliability are improved, the overhaul time is shortened, the dismounting efficiency of the fan and the motor coupler is improved, the labor force participation is reduced, and the labor intensity of personnel is reduced;
(2) the utility model is used for disassembling the wheel hub with smaller interference, and the wheel hub with larger interference is disassembled by frequently adopting a heating method and matching with a hydraulic jack or a screw jack, thereby being convenient and rapid, and saving time and labor;
(3) the utility model selects the jack with the diameter less than 32T to match with the lengthening pipe, can aim at the disassembly work of the coupler with the diameter less than or equal to 300mm, and has wider range and convenient carrying.

Left side axle sleeve 3 includes that four axle sleeve units and evenly distributed hold in a left side draw frame 1 edge, right side axle sleeve 4 includes that five axle sleeve units and evenly distributed hold in the right side and draw frame 2 edge, 45# steel machine-shaping, then weld in proper order on holding and draw the frame, left side axle sleeve 3 and right axle sleeve 4 are the nested setting in mutual interval, the axle sleeve unit that is close to connecting bolt 5 top and the axle sleeve unit that is close to the nut of screwing belong to same holding and draw the frame, a left side holds and draws frame 1 and right side and hold and draw frame 2 formation hinge formula structure. The connecting bolt 5 is inserted into the left shaft sleeve 3 and the right shaft sleeve 4, and the nuts are screwed to fix the tail end of the connecting bolt 5.
The installation and use method comprises the following steps:
aligning a left shaft sleeve 3 and a right shaft sleeve 4 of the left and right tensile frames 2;
inserting the connecting bolts 5 into all shaft sleeve holes;
locking and screwing the nut;
placing the assembled folding disassembling tool on the half coupling;
a jack is arranged in the middle position in the frame;
and (5) jacking the jack and disassembling the coupler.
If the coupling fails, a heated coupling approach may be used.
In addition to the above embodiments, the present invention may have other embodiments; all technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
