By means of the looping type spanner, the labor intensity of maintenance personnel is relieved effectively, the working efficiency is improved greatly, and the maintenance quality is ensured.
Description
Technical field
The utility model relates to the dismounting of steam-electric generating set shafting TSI probe, installation special tool, refers to especially a kind of loop type spanner.
Technical background
TSI shafting monitoring is widely used in the industries such as electric power, oil, chemical industry, metallurgy; the radial vibration of the axle of the large-scale steamer machineries such as steam turbine, the hydraulic turbine, generator, air blast, axial displacement, axle rotating speed, differential expansion, bias etc. are carried out to on-line measurement and safeguard protection, and the aspect such as rotor dynamics research and accessory size check.
In order to protect the safe operation of steam-electric generating set shafting; above the axle sleeve of high, medium and low cylinder pressure and generator; same vertical plane, apportion both sides (being commonly called as X-axis, Y-axis) are 90 ° of angles 8mm steam turbine monitoring system (TSI) vibration probe (installing altogether 16) are installed; the Vibration Condition of on line real-time monitoring axle system, plays very important protective effect.When safe range that the axle vibration values that is a part surpass to be set, steam turbine main protection system (ETS) is sent protection action command: steam turbine tripping operation, generator off-the-line.
Turbo-generator Set is through macrocyclic production run, and shafting monitoring inevitably some faults can occur, for example pop one's head in generation problem, fault, and linear bad is a bad point, repair and maintenance personnel will apply for arranging to take off lid maintenance when unit outage.Because the position working space that TSI probe is installed is very narrow and small, probe only has 60mm with the lateral separation of rotating machinery, extremely inconvenient while using the instrument maintenance such as common wrench, time and effort consuming, when installing, adjusting, need to rotate probe, the cable thereupon rotating easily twists off, cause cable and probe separation, cause measurement data mistake, what a probe is installed on average will be about 1 hour.Now, if there is foreign matter to fall in axle system as pad falls down accidentally, in servicely will cause that steam-electric generating set shafting vibration values exceeds standard, unit is forced to out of servicely, brings very big loss and potential safety hazard to the continuous production run of electric power, its consequence is hardly imaginable.
In steam-electric generating set shafting small space, the dismounting of existing TSI shafting monitoring probe and installation difficulty, when maintenance, operating pressure is large, and efficiency is low, and these problems are needed solution badly.
Summary of the invention
The purpose of this utility model will provide exactly a kind of and can conscientiously solve in steam-electric generating set shafting small space, and TSI probe is dismantled and difficult problem is installed, and guarantees maintenance, the work quality of safeguarding, the loop type spanner of increasing work efficiency.
For achieving the above object, the loop type spanner that the utility model is designed, comprise inner sleeve and outer sleeve that coaxial package coordinates, the two ends of outer sleeve are stretched out at the two ends of described inner sleeve, described inner sleeve and outer sleeve are provided with handle with the outside, one end in orientation, the cross section of described inner sleeve is round outside but spuare inside shape structure, and the cross section of described outer sleeve is the outer hexagonal structure of inner circle.
Further, the handle on described inner sleeve and outer sleeve is provided with two, and two handles are arranged symmetrically with.
Further, the caliber of described inner sleeve is 14-18mm, and length is 600mm.
Again further, the caliber of described outer sleeve is 20-24mm, and length is 400mm.
Further, the length of described handle is 100mm.
TSI shafting monitoring is to consist of probe, extension cable, fore-lying device and control panel and rack unit.The utility model is as the TSI special spanner of popping one's head in, and loop type spanner designs and produces according to the own characteristic of TSI probe.During the utility model work, adopt loop type spanner, maintainer reduces to 2 people by 3-4 people, and the working time greatly reduces, and foreshortens in 20 minutes, has effectively reduced maintainer's labour intensity, has greatly improved operating efficiency, has guaranteed repair quality.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Loop type spanner shown in Fig. 1-3, comprise inner sleeve 1 and outer sleeve 2 that coaxial package coordinates, the two ends of outer sleeve 2 are stretched out at the two ends of inner sleeve 1, inner sleeve 1 and outer sleeve 2 are provided with handle 3 with the outside, one end in orientation, the cross section of inner sleeve 1 is round outside but spuare inside shape structure, the cross section of outer sleeve 2 is the outer hexagonal structure of inner circle, and the handle 3 on inner sleeve 1 and outer sleeve 2 is provided with two, and two handles are arranged symmetrically with.
The caliber of inner sleeve 1 is 14-18mm, and length is 600mm, and the caliber of outer sleeve 2 is 20-24mm, and length is 400mm, and the length of handle 3 is 100mm.
As an embodiment, loop type spanner is to be combined by inner sleeve 1, outer sleeve 2.Inner sleeve 1 is selected stainless steel tube, the total length 600mm of φ 16, the interior square of 8mm * 8mm is made in one end according to TSI8mm probe screw rod feature, for fixing, rotating detector, each installs long 100mm rotating handles 3 other end both sides, and one end that handle 3 is installed is simultaneously also the leading-out terminal of probe lead wire; Outer sleeve 2 is selected by the stainless steel tube of φ 22, total length 400mm, and interior hexagon is made according to TSI8mm probe screw rod upper cap nut size in one end, for embedding the nut on 8mm probe, is convenient to fastening probe, and each installs long 100mm rotating handles 3 other end both sides.
The utility model is applied on specific TSI probe, and as shown in Figure 4, the 8mm vibration probe of TSI probe is comprised of hose armoured cable 4, spanner working face 5, cored screw housing 6, clamp nut 7 and probe sensing element 8 structure of TSI probe.Probe sensing element 8 is installed in cored screw housing 6 one end, and for supporting probe head, the other end is positive square, spanner working face 5 and hose armoured cable 4, external extension cable.Clamping structure when cored screw housing 6, the whole conduct of clamp nut 7 are installed.
