Description
technical field:
The present invention relates to a kind of for carrying out tonometric a kind of measuring channel dredger in the adverse circumstances of emplastic or easily bond (as coal gas, heavy oil etc.).
background technology:
A large amount of coal tar easily bondd is contained in coke oven or blast furnace gas in thermal power plant boiler combustion medium; the sampling pipe when pressure measxurement is because the tack of coal tar is very strong; particularly continuous measurement; long-play; coal tar sticks to measuring tube road junction, is blocked by pressure port gradually, causes instrument normally to work; because gas pressure measuring point relates to boiler main fuel trip protection, pressure measxurement blockage problem brings certain hidden danger to safe operation of the boiler.Former dredging method is that maintainer removes measuring channel joint, manually dredges, and its shortcoming is 1, causes a large amount of poisonous medium to leak, the safety of harm maintainer; 2, boiler main fuel trip protection will be exited before dredging; 3, the plant maintenance amount of maintainer is added.

4. the present invention uses worm and gear assembly to make operation more easy to be laborsaving.
5. the present invention adopts the effect of airtight and watertight padding, effectively prevents dielectric leakage.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is upward view of the present invention.
Fig. 3 is the A-A profile of Fig. 2.
Fig. 4 is the B-B profile of Fig. 2.
In figure: worm gear 1, worm screw 2, only lock pin 3, turning handle 4, spring 5, displacement chamber 6, perching knife support 7, slip weight 8, slide link 9, spherical linkage 10, umbrella perching knife 11, pressure pipe 12, measurement pipeline 13, stop block 14, airtight and watertight padding 15, fixed stop 16, steel wire rope 17, perching knife connecting rod 18.
detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further described.
As Figure 1-4, the measuring channel dredger of the present embodiment, comprise the tubular shell that one end open is closed in one end, perching knife support 7 is installed inside described tubular shell, umbrella perching knife 11 installed by described perching knife support, described perching knife support connects lift drive unit, and described umbrella perching knife also connects constriction device.
Described measuring channel dredger, described lift drive unit comprises the displacement chamber 6 be arranged on inside described tubular shell, the perching knife connecting rod 18 be connected with described perching knife support, fixed stop 16 is provided with in the middle part of described perching knife connecting rod, described fixed stop is arranged in described displacement chamber, described fixed stop top is provided with spring 5, the other end of described spring is arranged on the upside of described displacement chamber, described perching knife connecting rod passes described displacement chamber and is connected with worm screw 2, described worm screw engages with turbine 1, described turbine compresses by stopping lock pin 3, described only lock pin is through the sidewall of described tubular shell, the axle of described turbine is connected with turning handle 4 through the sidewall of described tubular shell.
Described measuring channel dredger, described constriction device comprises the slip weight 8 be arranged on described perching knife connecting rod, described slip weight connects the middle part of described umbrella perching knife by slide link 9, described slip weight connects described turbine by steel wire rope 17, and described perching knife connecting rod bottom is also provided with the stop block 14 of slip weight.
Described measuring channel dredger, is connected by ball-type hinge 10 between described perching knife support and described umbrella perching knife.
Described measuring channel dredger, is provided with airtight and watertight padding 15 between described displacement chamber and described perching knife connecting rod.
The course of work:
As shown in Figure 1, the present invention is welded on measuring channel 13, once measure technique to need dredging, pull only lock pin 3, worm and gear is threaded off, umbrella perching knife 11 along with spring 5 pretightning force recovery in parcel shape move down, because now worm gear is in can natural rotation state, the steel wire rope now between slip weight 8 and worm gear 2 moves downward without resistance under the traction of weight gravity, drives worm gear to rotate in the other direction, add the acceleration of slip weight weight simultaneously, remove measuring channel attachment rapidly.Because be temporary impact, instantaneous block clearing, promote umbrella perching knife by handle at once, so the instantaneous static pressure of pressure pipe pressure, measured value can not fall suddenly, and influential system runs.
When normally measuring after block clearing, swinging handle 4, along with the lifting of worm and gear, the compression of spring 5, perching knife support 7 comprises all components such as umbrella perching knife and is promoted to spring early warning location status, now along with the rotation of worm gear 2, move slip weight 8 move upward by inner wire rope band, slip weight drives umbrella perching knife 11 to be contracted to alert status by slide link 9.Only lock pin 3 locates worm gear 2 and worm screw 1 is meshing.
In A-A face, when technique is normally measured, umbrella perching knife 11, by spherical linkage 10, centered by perching knife connecting rod, shrinks in umbrella with slide link 9 with slip weight 8 together with the effect of spherical linkage.When pipeline needs dredging, perching knife support 7 passes through the effect of spring force above, moves downward rapidly, in folding process, umbrella shape blade 11 nature, to surrounding diffusion, roots out attachment around in parcel dress, slip weight 8 gravity moves down simultaneously, by spherical linkage to perching knife acceleration.The tamper in pipeline can be removed so largely.
In sum, this dredger can carry out the operation of pressure measurement pipe-dredging by Non-disturbance online easily voluntarily, anti-block apparatus is purged relative to compressed air, its umbrella type perching knife dredging ability more by force, more thoroughly, adopts the lifting of worm and gear to carry out the application of Compress Spring, so its energy consumed is lower, by the united application of the pretightning force of spring and the acceleration of weight, its novel structure, easy for installation, fully ensure production safety stable operation, be worthy of popularization.
Below be only most preferred embodiment of the present invention, method of the present invention includes but not limited to the technical scheme disclosed in above-described embodiment, and unaccomplished matter of the present invention belongs to the common practise of those skilled in the art.
