Description
Technical field
The utility model belongs to hydrogenerator installation and repairing field, in particular to hydroelectric generating set rotor keystroke is special
Use tool.
Background technique
The rotor of hydrogenerator during the installation process, needs for magnetic pole to be mounted in the mounting groove of magnetic yoke, then again will
The major and minor key progress of magnetic pole is urgent, to ensure that the magnetic pole of rotor in the process of running has enough tension.Since pole wedge is initial
After being inserted into the mounting groove of magnetic yoke, still there is very long one section of exposing, for the major and minor key wedging that will cooperate, reaches expected tensile force,
It is mainly firmly struck using sledgehammer in current construction tight.The construction method is time-consuming, laborious and urgent dynamics is uneven, especially
In the case where not hanging out rotor, in narrow space, using sledgehammer, the urgent work of key can not be effectively carried out.Together
When, with the increase for striking clamp force degree, pole wedge amount of deflection is also increased with it, and pole wedge will bend at this time, need to constantly by
It strikes tightly again after pulling out just, and bending is easy to make pole wedge that fatigue fracture, whole process inefficiency occur repeatedly in this way.In addition,
During tapping pole wedge, sledgehammer is with pole wedge end contact site because human factor exerts oneself to be difficult to concentrate on center
Domain is easy to happen sideslip, injures the magnetic pole of personnel at one's side and underface or side by a crashing object, since pole coil is copper material, in weight
It hits down and is easily deformed and damages magnetic pole, therefore there are serious security risks for the construction method.
Summary of the invention
The purpose of the utility model is to overcome the rotor of existing hydrogenerator existing defects during the installation process, mention
For a kind of safety, the specific purpose tool of the hydroelectric generating set rotor keystroke to work suitable for small space keystroke.
Technical solution used by the utility model is a kind of specific purpose tool of hydroelectric generating set rotor keystroke, main points
It is that it is made of guiding axis, weight head, weight handle, force block, guide sleeve, stud, force block is made in one end of guiding axis
On be formed with the screw hole matched with stud, the stud of guiding axis is connect with force block, and weight headgear is outside guiding axis, along guiding axis
It moves up and down, the two sides of weight head are fixed with weight handle.
The utility model is fixed by guiding axis by the motion profile of weight head, and is moved up and down along axis, is related to
Space it is small, weight head will not occur during keystroke and beat deviation, it is easy to operate, laborsaving, effectively prevent injuring people from periphery
The security risk of member and part of appliance.
Lengthening guiding axis is further fixed on above guiding axis.Extend the length of guiding axis using guiding axis is lengthened, it can root
It is used according to construction location and actual needs, the weight of cooperation adjustment weight increases hitting dynamics, advantageously reduces staff's
Working strength improves working efficiency, while convenient for collecting.
Guiding axis, lengthening guiding axis are round steel, pass through Stud connection therebetween.
Clump weight is fixedly arranged above in weight head.By increasing clump weight, make the weight-adjustable of weight head.It can be according to existing
The actual needs adjustment nose heave amount of weight, by key beat more consolidation in place, while also accommodating different units, different type key
Keystroke requirement.
Guide sleeve by fixing bottom plate, hollow cylinder is constituted, fixed bottom plate is bolted with force block.
With multiple and different specifications, the guide sleeve matched with the size of key.
The link position of fixed bottom plate and force block is fixed, and unified fixation bottom plate cooperates different hollow cylinders to be made not
Same guide sleeve, to adapt to various sizes of key.
The utility model is efficient, laborsaving, and the bending being likely to occur during pole wedge can be overcome urgent avoids pole wedge
The generation of fatigue fracture, while the risk that effective prevention periphery personnel and magnetic pole are injured by a crashing object, ensure construction safety.Suitable for difference
Unit and different type pole wedge keystroke work, be also applied for narrow space, the situation of person works' inconvenience.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model
Wherein: 1- guiding axis, 2- weight head, 3- weight handle, 4- force block, 5- guide sleeve, 51 fixed bottom plates, 52 is empty
Heart cylinder, 6- lengthen guiding axis, 7- clump weight.
Specific embodiment
The utility model is further described below in conjunction with attached drawing
As shown in Figure 1, a kind of specific purpose tool of hydroelectric generating set rotor keystroke, it is by guiding axis 1, weight head 2, again
It hammers handle 3 into shape, force block 4, guide sleeve 5, lengthen guiding axis 6, the composition of clump weight 7.Stud, force block is made in one end of guiding axis 1
On be formed with the screw hole matched with stud, the stud of guiding axis is connect with force block 4, weight headgear outside guiding axis, along guiding
Axis moves up and down, and the two sides of weight head are fixed with weight handle.Guiding axis 1, lengthening guiding axis 6 are made for round steel, the two
Between pass through Stud connection.The quantity for lengthening guiding axis can be according to being actually increased and decreased, will when needing to increase guiding shaft length
Guiding axis 6 is lengthened by Stud connection to 1 top of guiding axis, to increase the hoisting depth range of weight head 2, cooperation adjustment weight
First 2 and clump weight 7 weight, so that the hoisting depth of weight head 2 is suitble to the actual position of construction at one, advantageously reduce work
The working strength of personnel improves working efficiency.When needing to adjust the nose heave amount of weight, a certain number of clump weights can be passed through spiral shell
Column is fastened on weight head 2, to change the dynamics tapped, by key beat more consolidation in place, while also accommodating difference
The requirement of unit, different parts keystroke.
Guide sleeve 5 is made of fixed bottom plate 51, hollow cylinder 52, and fixed bottom plate is bolted with force block 4.It is
Changeable type has multiple and different specifications, the guide sleeve matched with the size of key, the link position of fixed bottom plate and force block
Fixed, unified fixation bottom plate cooperates different hollow cylinders that different guide sleeves is made, to adapt to various sizes of key.When into
When the keystroke work of row different type key, the fixed bolt of the fixed bottom plate of guide sleeve 5 need to be only removed, guide sleeve 5 is changed to suitable
It can be used after the size of conjunction, expanded the scope of application of the tool.
When the utility model is used, guide sleeve 5 is placed in needs on urgent pole wedge, and keeps guiding axis 1 vertically,
Two people cooperation discharges after weight head 2 is promoted to specified altitude, and weight head 2 lands along guiding axis 1 taps force block 4, to make
The major and minor key uniform stressed matched is urgent downwards.
