Description
[technical field]
This utility model belongs to hydraulic turbine maintenance technique field, particularly to a kind of tool for pulling out locating pin.
[background technology]
As it is shown in figure 1, water oil guide groove and a watt frame on the hydraulic turbine are fixed by alignment pin, when needs carry out keeping in repair or changing dismounting, then need to extract alignment pin.Existing instrument uses cushion block, extracts bolt, extracts nut and pneumatic impact wrench realizes extracting alignment pin from watt frame.Owing to alignment pin work space is limited, pneumatic impact wrench uses very inconvenient, and instrument the most often occurs that screw rod, nut screw thread are extracted in damage, causes alignment pin to extract difficulty.
[utility model content]
For solving the problem that prior art exists, this utility model provides a kind of tool for pulling out locating pin, and this utility model assembles simple, easy to operate, will not damage equipment and personnel.
For reaching above-mentioned purpose, this utility model is achieved by the following technical solutions:
A kind of tool for pulling out locating pin, including extracting screw rod；Described extracting is arranged with bracer and a hollow jack on screw rod；A described bracer one end arranges cavity, and described hollow jack connects power source；During use, the one end extracting screw rod is connected with alignment pin to be extracted, and a bracer contacts with the fixture of alignment pin, and cavity is arranged on above alignment pin, extracts the screw rod other end and hollow jack and a bracer is fixed by adjusting nut.
Also include that adaptor, described adaptor connect and extract screw rod and alignment pin.
Described hollow jack is hydraulic jack, and power source is hydraulic hand-pump.
Described cavity is column structure, and the diameter of cavity is more than the diameter of alignment pin, and the height of cavity is more than the length of alignment pin.
During use, extract screw rod, a bracer, hollow jack and alignment pin and be coaxially disposed.
Described adjusting nut is locking nut.
Relative to prior art, this utility model has the following technical effect that
This utility model includes extracting screw rod, bracer and hollow jack；Propping up bracer and arrange cavity, the operational forces of hollow jack all acts on the resistance overcoming alignment pin.Screw motion is extracted in the work drive of hollow jack, extracts screw rod and drives alignment pin to going out motion in cavity, it is achieved that extracting of alignment pin.This utility model assembles simple, fully meets and extracts water oil guide groove, the work of watt frame alignment pin, assembles simple, easy to operate, will not damage equipment and personnel.And easy and simple to handle laborsaving, instrument in use screw thread geo-stationary, the Impact direction of power is simple, and only vertical pull out force, screw thread will not produce and bite.Improving the working environment of workers and working strength, work efficiency is greatly improved, and saves human cost.
Further, the design centre of instrument, manufacturing center, work centre all with load center point-blank, prevent skidding damage from extracting screw rod, nut screw thread.
Further, hollow jack uses hydraulic jack, it is ensured that instrument did not bounced in power release moment.The use of hydraulic pressure handlance, makes working environment be improved, and facilitates workman's maintenance, Pressure gauge can the size of monitoring power at any time, the equipment that eliminates works overloadingly the potential safety hazard brought.
[accompanying drawing explanation]
Fig. 1 is the tool for pulling out locating pin schematic diagram of prior art；
Fig. 2 is this utility model tool for pulling out locating pin schematic diagram.
Wherein, 1 be oil groove, 2 be watt frame, 3 be alignment pin, 4 be bracer, 5 for extract screw rod, 6 be hollow jack, 7 be adjusting nut.
[detailed description of the invention]
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in detail, but in description of the present utility model, it will be appreciated that, embodiment described by this utility model is exemplary, design parameter appeared in description is for only for ease of description this utility model, and it is not intended that to restriction of the present utility model.
As in figure 2 it is shown, this instrument by hollow jack 6, hydraulic hand-pump, extract screw rod 5, adjusting nut 7, bracer 4 and adaptor and form.Adaptor is mainly used in the switching extracting screw rod 5 screw thread with target screw thread.
Described bracer 4 one end arranges cavity, and described hollow jack 6 connects power source；During use, the one end extracting screw rod 5 is connected with alignment pin 3 to be extracted, and a bracer 4 contacts with the fixture of alignment pin 3, and cavity is arranged on above alignment pin 3, extracts screw rod 5 other end and hollow jack 6 and a bracer 4 is fixed by adjusting nut 7.Described hollow jack 6 is hydraulic jack, and power source is hydraulic hand-pump.Described cavity is column structure, and the diameter of cavity is more than the diameter of alignment pin, and the height of cavity is more than the length of alignment pin.During use, extract screw rod 5, a bracer 4, hollow jack 6 and alignment pin 3 and be coaxially disposed.Described adjusting nut 7 is locking nut, prevents from loosening.
The installation and application of this practicality is as follows:
New tool screws in alignment pin 3 screwed hole to be extracted with extracting screw rod 5, due to be without stress screw in, therefore, it is possible to ensure that screwing length and bolt 5 screw thread are injury-free, then by extracting screw rod 5, the bracer 4 having centre bore is loaded, ensure that hollow jack 6 has a stress point, prop up the displacement that bracer 4 alignment pin to be met 3 is extracted simultaneously, secondly load hollow jack 6, extract screw rod 5 and pass from hollow jack, adjusting nut 7 screws in and extracts screw rod 5, with hollow jack 6 upper-end contact.Connecting hollow jack 6 and handlance, suppress hollow jack 6, hollow jack 6 is extracted screw rod by adjusting nut 7 and is extracted by alignment pin 3.
This tool assemble is all to work under the state of not stressing, normally put in place therefore, it is possible to ensure that each parts connect, all with load center point-blank, thus the operational forces of hollow jack 6 all acts on the resistance overcoming alignment pin 3 for the design centre of instrument, manufacturing center, work centre.Hollow jack 6 uses hydraulic jack, it is ensured that instrument did not bounced in power release moment.The use of hydraulic pressure handlance, working environment is made to be improved, facilitate workman's maintenance, Pressure gauge can the size of monitoring power at any time, eliminating the potential safety hazard that equipment overwork brings, the use of this instrument fully meets extracts water oil guide groove, the work of watt frame alignment pin, assembles simple, easy to operate, equipment and personnel will not be damaged.
After using this utility model, the effect producing maintenance acquirement is as follows:
In terms of manpower: before this instrument uses, extract water oil guide groove, a watt frame alignment pin needs 4 personal work 8 hours, the longest needs 15 hours (overtime work), now only need two personal works 2 hours, it is no longer than 4 hours, in the case of manpower anxiety, a people can complete whole work.Save manpower 56 hours, directly save 2600 yuan/platform of artificial expenditure, improve the working environment of workers and working strength, improve equipment personnel safety.
Above, preferred embodiment the most of the present utility model, it is not limited only to practical range of the present utility model, all equivalence changes done according to the content of this utility model scope and modification, all should be technology category of the present utility model.
