Abstract
The utility model relates to a kind of plunger displacement pump arc axle bearing pin tool specially for attaching and detaching.Mainly solve the loaded down with trivial details problem wasted time and energy of arc axle bearing pin disassembly process in the existing pump maintenance process existed in prior art.It is characterized in that: circular top cover (1) is equipped with at described cylinder (2) top, circular top cover (1) middle part has circular hole, single ended bolt (3) is passed by circular hole by directly over circular top cover, single ended bolt (3) is covered on circular top cover top, and circular top cover and single ended bolt (3) are matched in clearance; Single ended bolt (3) circular top cover top clamp nut (4).This plunger displacement pump arc axle bearing pin tool specially for attaching and detaching, can reduce maintenance personal's workload, increase work efficiency, time saving and energy saving.
Description
Technical field
The utility model relates to a kind of bearing pin tool specially for attaching and detaching in petrochemical machinery maintenance field, particularly a kind of plunger displacement pump arc axle bearing pin tool specially for attaching and detaching.
Background technology
In the pump maintenance process that Petro-Chemical Machinery is daily, arc axle bearing is rapid wear bearing, arc axle pivot pin is unidirectionally extract form, can only be extracted by top, in order to extract arc axle pivot pin, stroke adjustment assembly is dismantled by maintenance personal from stroke adjustment place, removes eccentric wheel assembly, arc axle is removed from pump, then pivot pin is upwards pounded out in pivot pin downside from arc axle.After changing bearing, then recover pump, unloading process is loaded down with trivial details, also again will correct stroke, and workload is very large, consuming time, effort.
Summary of the invention
Technical problem to be solved in the utility model overcomes the loaded down with trivial details problem wasted time and energy of arc axle bearing pin disassembly process in the existing pump maintenance process that exists in background technology, and a kind of plunger displacement pump arc axle bearing pin tool specially for attaching and detaching is provided, this plunger displacement pump arc axle bearing pin tool specially for attaching and detaching, maintenance personal's workload can be reduced, increase work efficiency, time saving and energy saving, efficiency is high.
The invention for solving the technical problem reaches by following technical scheme: this plunger displacement pump arc axle bearing pin tool specially for attaching and detaching, comprise main body cylinder, described barrel top is equipped with circular top cover, circular hole is had in the middle part of circular top cover, single ended bolt is passed by circular hole by directly over circular top cover, single ended bolt is covered on circular top cover top, and circular top cover and single ended bolt are matched in clearance; Single ended bolt circular top cover top clamp nut.
The utility model can have following beneficial effect compared with above-mentioned background technology: this plunger displacement pump arc axle bearing pin tool specially for attaching and detaching is owing to adopting above-mentioned flow process, before use specific purpose tool, maintenance once, experienced operator needs 1 hour 20 minutes single maintenance time, use after specific purpose tool, 15 minutes single maintenance time of common laborer.This specific purpose tool makes and uses simple, and maintenance personal avoids and carries out a large amount of dismountings, recovery, adjustment work.Reduce maintenance time, reduce maintenance difficulty, increase work efficiency.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the utility model using state structural representations.
In figure: 1-circular top cover, 2-cylinder, 3-single ended bolt, 4-nut, 5-bearing pin, the arc axle of 6-.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in accompanying drawing 1 composition graphs body 2, this plunger displacement pump arc axle bearing pin tool specially for attaching and detaching, comprises main body cylinder 2, and circular top cover 1 is equipped with at cylinder 2 top, and pass single ended bolt 3 by directly over circular top cover, circular top cover is threaded with single ended bolt 3; Single ended bolt 3 bottom clamp nut 4; Warp in described cylinder 2, external diameter, be highly Φ 25 × Φ 35 × 400; Warp in circular top cover, external diameter, be highly Φ 18 × Φ 36 × 8.
When this plunger displacement pump arc axle bearing pin tool specially for attaching and detaching uses, in first time maintenance process, the bearing pin 5 on arc axle 6 is pounded out by conventional method, processing screw hole is carried out to bearing pin 5 center, install and reset.Only specific purpose tool need be adopted in maintenance process afterwards, by cylinder just to above pivot pin, circular top cover on round barrel cover, bolt by directly over through circular top cover, enter into pivot pin screw, and carry out fastening, when bolt is tightly dead, clamp nut 4, bearing pin overcome friction will screw out and enters into cylinder upward, thus reaches the object of extracting bearing pin.
