Detailed description of the invention

Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.

Refer to Fig. 1, a kind of following type constant hanger, including following unit, prop up and hang unit and Storage Unit, described unit of following includes axle 10, clutch shaft bearing 3, 3rd gear 8, second gear 7, steel wire rope roll 11, steel wire rope 13 and assembly pulley 12, axle 10 is fixed on top by clutch shaft bearing 3, axle 10 is provided with the 3rd gear 8, 3rd gear 8 be connected below the second gear 7, steel wire rope roll 11 is arranged on axle 10 bottom, steel wire rope 13 is arranged on steel wire rope roll 11, assembly pulley 12 is connected with steel wire rope roll 11 by steel wire rope 13, hanging unit is positioned at the right side following unit, hanging unit includes the first gear 6, second bearing 17, sleeve 14, pull bar 15 and damping spring 16, sleeve 14 is arranged on top by the second bearing 17, first gear 6 is arranged on the middle part of sleeve 14 and is connected with the second gear 7, pull bar 15 is arranged in sleeve 14 and extends to outside sleeve 14, damping spring 16 is arranged on the lower end of pull bar 15 and damping spring 16 is connected with hot-flow flue 20, Storage Unit is positioned at the left side following unit, Storage Unit includes energy-storaging spring 4, fixing device 1, gear plate 5, guider 2 and the 3rd bearing 18, energy-storaging spring 4 is arranged on top by fixing device 1, gear plate 5 is arranged on top by the 3rd bearing 18, gear plate 5 is provided with guider 2 and the 4th gear 9, 4th gear 9 is connected with the 3rd gear 8.Damping spring 16 adopts the material of the high coefficient of stiffiness to make, it is possible to vibrations when preventing equipment from running hang, to propping up, the fatigue rupture that assembly produces, thus suppressing the vibrations of pipeline and consuming its vibration energy, axle 10 adopts stainless steel material to make.Pull bar 15 is threaded connection and is arranged in sleeve 14.

Operation principle of the present utility model is: when thermal walking is downward: boiler hot air interface 21 is when the move under influence of boiler 19 water-cooling wall flatulence of heat type stress, by being wrapped in steel wire rope 13 on steel wire rope roll 11 and assembly pulley 12, the rectilinear motion of steel wire rope 13 is become the rotation of axle 10, driving the first gear 6 by the second gear 7, the 3rd gear 8 drives the 4th gear 9 simultaneously；First gear 6 band moving sleeve 14 rotates, pull bar 15 is screwed out sleeve 14 simultaneously, hot-flow flue 20 is compensated because of the downward thermal walking of boiler hot air interface 21 with this, damping spring 16 makes the work load Distributing loads more than pipeline cold conditions, thus suppressing the vibrations of pipeline and consuming its vibration energy, if equipment does not shake, it is possible to cancel damping spring 16 thus simplified system and reduction cost；4th gear 9 driven gear plate 5 horizontal movement, thus compression or stretching energy-storaging spring 4, is converted into energy the potential energy of energy-storaging spring 4 and is maintained.When boiler 19 is stopped transport, hot air interface 21 recovers cold conditions absolute altitude (namely having displacement upwards) gradually, steel wire rope 13 unclamps immediately, energy-storaging spring 4 restricted releases, the potential energy of energy-storaging spring 4 is the kinetic energy of the horizontal movement of gear plate 5, thus driving the first gear 6, second gear 7, 3rd gear 8 and the 4th gear 9 carry out the linkage contrary with equipment initial operating stage, the steel wire rope 13 so following unit is wound onto on steel wire rope roll 11, prop up the sleeve 14 hanging unit to rotate forward, pull bar 15 is screwed in sleeve 14, its turnover size is consistent with the thermal walking of hot air interface 21.When thermal walking upwards time, as long as energy-storaging spring 4 being adjusted by value of calculation before putting into operation, it is made to store enough potential energy, when equipment initial operating stage upwards expands, steel wire rope 13 unclamps, energy-storaging spring 4 potential energy release, by actuator drives sleeve 14 raising rod 15, this process with thermal walking upwards time stoppage in transit situation identical；When the downward equipment of thermal walking is stopped transport, the action during action situation of mechanism and thermal walking equipment startup upwards is identical.This device safety in utilization is good, has stopped to cause air channel load transfer to interface because loading is less thus the accident causing equipment to be damaged；Bearing capacity is strong, and compensation dosage is big, not by spring load, effect length, as long as space is enough, it is possible to compensate 500-1000mm, is particularly well-suited to the hot-flow flue design of Large Ultra-Supercritical tower-type furnace；Adopting purely mechanic assembly, simple and reliable for structure, the thermal walking that pull bar 15 adjusts with interface is synchronously performed, and tracing ability is good, is absent from " delay link "；The flatulence of heat type masterpiece utilizing equipment is power, it is not necessary to other energy, and reliability is high；Volume is little, takes up room little, installs simple and convenient, and cost is low；This device is applicable to different pipelines and cigarette air channel, applied widely.

Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible to make a variety of changes under the premise without departing from this patent objective.
