Description

The equipment of the holding equipment of threaded connection is positioned for during built on stilts assembly and disassembly
Technical field
The present invention relates to for positioning the equipment for keeping equipment, on the one hand the holding equipment be used for nut and on the other hand use In the clamp nut of preload device, wherein, these equipment are used in varied situations has power with built on stilts assembly and disassembly Profit requires the threaded connection of two parts of the feature of the preamble of 1 and claim 2, two parts substantially level each other Ground is arranged.
Background technology
When the housing for the big part, such as turbomachinery that assembling is arranged each other horizontally, because the size of all parts, So being encountered difficulties during assembly and disassembly.In order to form persistently connection between all parts, case half is especially Low portion and upper part are separated into by horizontal component joint, and enduringly fastened followed by threaded connection.
Generally, screw is screwed in from lower case half portion into upper body half portion, so as under screw by hole from below Portion's free end can be used for together with nut driving.
By the screw-nut connection, part is fixed against each other with frictional engagement, because being subjected to the elongation of screw The nut of screw sum be screwed around together.According to material rule, the elongation causes to preload in screw, and it is applied on part Plus the normal force required for being connected for the part of frictional engagement.
It is favourable using hydraulic tensioning equipment particularly with the part of connection turbomachinery.These equipment connect in screw thread The nut connect hydraulically stretches screw first before then tightening.When remove stretching hydraulic pressure when, screw then by its from Body is supported in nut, and this maintains the elongation of screw and therefore maintains desired preloading.In order to disconnect threaded connection, nut energy It is enough to unload on the contrary, and then disconnected by hydraulically stretching screw again.
As interpreted at the beginning, big turbomachinery is typically flatly to separate its housing, and two shells Body half portion is connected using such as 65 kg screw and such as 25 kg nut.
Because the predetermined arrangement of screw, screwing for nut generally has to upper progress manually overhead, because Narrow space condition on the pedestal of turbomachinery and because for the supply line around turbomachinery, generally not The assembly and disassembly of nut may be carried out with the help of lift truck or other auxiliary equipments.
The above-mentioned assembly and disassembly for applying also for preload device, preload device has even 90 kg's heavier sometimes Weight, and the nut even than the threaded connection for housing parts to be connected is heavier.
According to assemble method so far, assembly and disassembly occurs on the crown of two people, and this is with regard to ergonomics and work It is not optimal for industry safety.
The content of the invention
Therefore it is an object of the invention to provide equipment, using the equipment, make on the one hand to be used for the screw thread of part to be connected The nut of connection and the clamp nut of another aspect preload device enter in built on stilts assembling and are used to be fastened to for be connected Part threaded connection screw optimum position.
According to the purpose of the present invention by being solved according to the equipment of claim 1 and claim 2.
Corresponding dependent claims are related to favourable further improvement.
It is that, for positioning the equipment for keeping equipment, on the one hand the holding equipment be used for nut and another according to the equipment of the present invention On the one hand it is used for the trip bolt of preload device, wherein, these equipment are used with built on stilts group installation and dismantling in varied situations Unload the threaded connection for being substantially arranged to two horizontal each other parts.
With the help of novel device, the built on stilts assembly and disassembly of threaded connection can be even under narrow steric requirements Also carry out without any problems, wherein, on the one hand the general principle of equipment ensures the spiral shell of the threaded connection for part to be connected Female best orientation, and on the other hand ensure best orientation of the clamp nut on screw for preload device.
By the novel device, prevent nut or the clamp nut for preload device from falling during assembly and disassembly Fall, so as to jeopardize assembler.
In addition, equipment ensures, on the one hand nut and on the other hand the clamp nut for preload device always finds phase For the optimum engagement point of the screw thread of screw, and on the one hand prevent tilt nut or on the other hand prevent the fastening of preload device Tilt nut.
