Description
Technical field
The invention belongs to train operation technical field of auxiliary equipment, be specifically related to a kind of electric locomotive automatic passing over of neutral section exchangeable ground magnetic inductor.
Background technology
Electric locomotive automatic passing over of neutral section ground magnetic inductor is the ground magnetic equipment of the vehicle-mounted auto-passing neutral section control system based on non-maintaining ground location technology.When electric locomotive passes through, the pre-buried automatic passing over of neutral section ground magnetic inductor in ground sends corresponding signal to locomotive, automatically complete electric locomotive power-off by vehicle-mounted inducing receiver and mistake individual-phase control device again and cross phase-splitting, to ensure that the safety of automatic passing over of neutral section is with reliable.At present, the electromagnetism pillow that domestic electrical locomotive automatic passing over of neutral section ground magnetic inductor uses on Ballast track, mainly contains two kinds, that is:
One is Backpack type electromagnetism pillow.This is the first generation bringing into use automatic passing over of neutral section ground magnetic inductor from electric locomotive, namely dovetail groove is opened in one end of type III concrete sleeper, magnet is put according to certain magnetic texure in groove, magnet is embedded in the dovetail groove of type III concrete sleeper, magnet and sleeper are wrapped with stainless steel cage by outside, with four fastened by screws, namely an electromagnetism pillow is combined to form, electromagnetism pillow is placed in the position that rail track specifies, lay upper rail above, electric locomotive sends corresponding signal by electromagnetism pillow and reaches the function that phase-splitting is crossed in power-off.Shortcoming: four screws of fastening stainless steel cage, in on-line running process, shake by train long term frequent, easily come off, and cause stainless steel cage to unclamp, cause magnet to get loose, lose, directly affect the safe operation of train; In addition, during the large machine tamping operation of rail track, sometimes because of four screw overlength or installation site not in place, cause tamping tool tamping operation to batter electromagnetism pillow.
The second is underpass type electromagnetism pillow.This is the second generation bringing into use automatic passing over of neutral section ground magnetic inductor from electric locomotive, namely magnet is placed on and integratedly in stainless steel cage is made into trapezoidal magnet steel, dovetail groove is opened in one end of type III concrete sleeper, pre-buried bracing frame, for supporting magnet steel, and make a call to a hole in groove bottom and penetrate sleeper, magnet steel is put into groove, pass in hole with bolt of long stem below, bolt one end and magnet steel bottom surface adopt screw threads for fastening to be connected, it is fastening in sleeper bottom surface that other end nut adds cottor pin, magnet steel bottom surface and side Magnetic adhesive simultaneously, glass cement is bonded and sealed, reach the object of fastening magnet steel, so just form an electromagnetism pillow, electromagnetism pillow is placed in the position that rail track specifies, lay upper rail above, electric locomotive sends corresponding signal by electromagnetism pillow and reaches the function that phase-splitting is crossed in power-off.Shortcoming: between magnet steel and sleeper, stationarity is poor, under wear screw and easily get loose, cause magnetic steel displacement, come off, lose, potential safety hazard is formed to locomotive safety running.Wearing bolt one end under cause is fastened on magnet steel, pass through screwed tight, reinforcement of weld (because magnet steel belongs to strong magnetic product) cannot be carried out, in addition magnet steel self weighs 20 jin, the punching shear of the long-term shaking force upper and lower by train wheel, locomotive operation, is only difficult to fix for a long time and support magnet steel, getting loose of bolt by a bolt, directly cause magnetic steel displacement until magnet steel comes off, loses, certain threat is formed to railway security.
Above two kinds of electromagnetism pillow is in concrete operation maintenance process, and all exist and change cumbersome, time-consumingly take material, a difficult problem for waste of manpower etc., current replacing mainly contains two kinds of modes:
One changes whole electromagnetism pillow, because general about 800 jin an of sleepers, add upper magnetic steel 20 jin, the gross weight of an electromagnetism pillow reaches 820 jin, and body weight is larger, move very hard, if whole replacing, some places are as the rail fastening in dismounting before and after bridge, tunnel place needs about totally 8 sleepers, and this need of work works department carries out, need operating personnel 10 people, need general about 60 minutes of activity duration.After replacing, power supply department personnel need to detect the technical data of installation site, electromagnetism pillow, reach requirement and have then changed, if power supply department detects do not reach requirement, then need works department again to change.Though the sleeper performance parameter after replacing can also re-use, but require and the value that do not have secondary to utilize because the technical data of magnet steel does not reach, last sleeper and magnet steel are wasted and are abandoned it.Electromagnetism pillow (first generation) of current Backpack type is all whole replacing.
The second only changes magnet steel.Underpass type electromagnetism pillow is only can change magnet steel in theory, and up to the present, that only have particular/special requirement, a small amount of scene is split type to be changed, and the overwhelming majority still adopts whole replacing.When electromagnetism pillow damage or technical data do not reach require time, adopt the mode changing magnet steel, work is needed to be engaged in, power supply department has coordinated jointly, first works department personnel dig a hole bottom sleeper, reach the requirement of power supply department personnel job area, power supply department personnel are responsible for dismounting, nut spanner below sleeper is unloaded, under magnet steel being prized with crowbar above, again new magnet steel gluing is put into groove, fix with bolt of long stem, tighten with nut below and plug cottor pin, requirement is reached after detecting with instrumentation, works department is responsible for filling out hole, compacting, lay railway ballast.This need of work operating personnel 6 people, changes general about 40 minutes of one piece of needs activity duration.All prize broken with 99% magnet steel under crowbar sled, there is no the value that secondary utilizes.Railroad industry has strict standard-required to the roadbed below sleeper, whether the compacting of roadbed directly determines safety and the speed of train operation, the operations such as " railroad safety management regulations " regulation can not at will be excavated, ditching, if necessary, must agree to through railway enterprises or sign security protocol, through strict, multidisciplinary examination and approval procedures, just construction operation can be carried out.Up to the present, the electromagnetism pillow of present this underpass type is changed to be still and is taked the whole mode changed, and still do not solve and only change the problem such as magnet steel, joint portion difficult management, this problem annoyings railway, power supply department all the time.
In a word, all there is many defects such as Sectors cooperation difficult coordination, time and effort consuming, waste resource, high cost in above-mentioned two kinds of modes.
