Abstract
The utility model discloses a manual turning tool for a vertical motor. The manual turning tool comprises a support plate and supporting arms. The support plate comprises a support plate body and two extending arms which extend from the support plate body. The extending arms and the support plate body are integratedly manufactured. The periphery of the support plate body corresponding to a shaft head is uniformly distributed with three or more through holes. The supporting arms are L-shaped structures and the quantity of the supporting arms is consistent with that of the extending arms. An end of each of the extending arms is vertically fixed with one end of a supporting arm, and the other end of the supporting arm extends to the opposite direction of the support plate. The manual turning tool has the advantages of simple structure, low cost, repeated use and convenient operation and is especially suitable for the manual turning of the vertical motor, when in turning, the support plate is fastened at the shaft head by using fixing bolts, then according to a machine pit ground structure position and a turning torque, a suitable push tube is sleeved, and the turning can be carried out.
Description
Technical field
The utility model relates to a kind of manual hand turning tool for vertical machine, belongs to vertical machine design, test, Installation and Debugging and maintenance field.
Background technology
In pumping plant, the supporting composition water pump assembly of large-scale three-phase vertical sync motor and water pump is used for upstream supplying water, and unit needs can be efficiently and safe and stable operation, and wherein a very important procedure is when mounted unit axis to be measured and adjusted.
The axis of so-called unit is exactly the geometric center lines of each link combination of unit rotating shaft, and the space angle relation of this line and runner plate working face and flange faying face formation.During the unit running, if there are the complications of axis, will make each parts produce beat.For example, have larger non-perpendicularity at thrust runner end face or two end face of flange, being reflected in water, to lead the throw at place just very large, more obvious to this phenomenon of suspension type unit.So in the situation that various complications and out of plumb all exist, unit will produce maximum beat.Due to the unit axis out of plumb, on-streamly will produce periodic unequal loading to thrust bearing, throw is excessive simultaneously also has a significant impact water pilot bearing and sealing thereof, causes unit to play pendulum.Therefore after the unit general assembly, for guaranteeing reliable and stable operation, make axis as far as possible near the desired center position, unit axis should be adjusted to the state perpendicular with the runner plate face.
The throw value that unit axis is just located by jiggering mode and measurement top guide bearing, lower guide bearing, collector ring, shaft coupling flange and water pilot bearing etc. is determined.Because measurement and the adjustment of unit axis is a loaded down with trivial details job, improves jiggering mode and hand turning tool and also seem particularly important.Because the capacity of large-scale three-phase vertical sync motor is larger, spindle nose apart from ground more than 1900mm, the hand turning tool of former disc type uses very inconvenience, and jiggering operating personnel can't reach, and do not make power, and the weight of former disc type hand turning tool is generally all near 300 kilograms, volume is larger, and weight is heavier, lifting inconvenience and uneconomical, this type of hand turning tool often is mounted the workman and abandons, and makes separately easy hand turning tool by oneself as required.This simple and easy hand turning tool is that recruitment some leftover pieces on the ground are welded, disposable often, make coarse and crude, through adjusting, to use dangerously, its surface is without any antirust processing, mostly all can not use when again overhauling to unit, disposable, can only again make when needing jiggering, be also a kind of waste.
The utility model content
The purpose of this utility model is to provide a kind of reusable, and the manual hand turning tool that is used for vertical machine easy and simple to handle.
for achieving the above object, the technical scheme that the utility model is taked is: a kind of manual hand turning tool for vertical machine, comprise supporting plate and support arm, described supporting plate comprises the supporting plate main body and stretches out support arm from what the supporting plate main body extended out more than two, stretch out support arm and the supporting plate main body is one-body molded, be evenly distributed with plural through hole on the supporting plate main body circumference corresponding with spindle nose, described support arm is the L-type structure, quantity is consistent with the quantity of stretching out support arm, every end that stretches out support arm vertically is fixed with an end of support arm, the other end of support arm extends to the opposite direction of supporting plate.
As the preferred technical scheme of the utility model, also comprise the ejector sleeve that equates with support arm quantity, described ejector sleeve internal diameter is greater than the support arm external diameter, and described ejector sleeve is enclosed within support arm and is not fixed on an end that stretches out on support arm.
As the preferred technical scheme of the utility model, describedly stretch out support arm and support arm is 4.
As the preferred technical scheme of the utility model, the quantity of described through hole is 6.
As the preferred technical scheme of the utility model, described support arm is welded on the described end that stretches out support arm.
As the preferred technical scheme of the utility model, described supporting plate material therefor is steel plate.
As the preferred technical scheme of the utility model, described support arm is the carbon structure hot rolled seamless steel tube of diameter 50mm.
As the preferred technical scheme of the utility model, the diameter of described through hole is 21.5mm.
The utility model is simple in structure, and cost is low, and is reusable, easy to operate, be specially adapted to the artificial jiggering of vertical machine, during jiggering, supporting plate is anchored on spindle nose with set bolt, then is inserted in suitable ejector sleeve according to earth construction position, machine hole and jiggering torque and can carries out jiggering.
Description of drawings
Fig. 1 is the front view of manual hand turning tool of the present utility model.
Fig. 2 is the lateral plan of manual hand turning tool of the present utility model.
Fig. 3 is the schematic diagram of installing and using of manual hand turning tool of the present utility model.
Below in conjunction with embodiment, the utility model is described further.
Embodiment
In the present embodiment, described supporting plate 1 comprises supporting plate main body 11 and 4 equally distributed support arms 12 that stretch out that extend out from supporting plate main body 11, stretch out support arm 12 one-body molded with supporting plate main body 11, be evenly distributed with 6 through holes 13 on supporting plate main body 11 circumference corresponding with spindle nose, described support arm 2 is the L-type structure, every end that stretches out support arm 12 is vertically welded with an end of support arm 2, the other end of support arm 2 extends to the opposite direction of supporting plate 1, and support arm is the carbon structure hot rolled seamless steel tube of diameter 50mm.
During use, supporting plate 1 is fixed on spindle nose 4 by through hole with set bolt 5, spindle nose 4 is an integral body with electric machine main shaft 6, even but jiggering is carried out in other end electric machine main shaft 6 rotations of promotion support arm 2.When the length of support arm 2 is inadequate, can add in addition ejector sleeve 3 when causing moment of torsion inadequate and be enclosed within on support arm 2, the ejector sleeve available internal diameter forms greater than the steel pipe cutting of Φ 50 left and right.
In Fig. 3, H is the operation height, can be according to site operation personnel's height design operation height.
