Abstract
The invention relates to a separated quick changing ground magnetic sensor, which belongs to the technical field of railway transportation facilities and mainly solves problems that the traditional integrated magnetic sensor is hard to detach, is time-consuming and laborsome and affects the operation of trains. The separated quick changing ground magnetic sensor comprises a protective cover, a magnetic body, a tightening piece, an embedded part and a sleeper, wherein the magnetic body comprises a magnet and a bottom support which are connected with each other through a bolt; the magnetic body is integrally connected with the embedded part through a bolt and the magnetic body and the embedded part act upon each other through magnetic force to prevent loosening; and the protective cover covers outside the magnetic body and is locked together with the embedded part through the tightening piece. The lower end of the protective cover is provided with a sealing strip; hinge bolts are arranged on one side or two sides of the magnetic sensor and penetrate through the protective cover and the embedded part so as to fix the protective cover and the embedded part; and pin holes are formed in the bottom support. According to the invention, the ground magnetic sensor can be singly and quickly changed, the changing cost is greatly reduced, the ground magnetic sensor can be quickly changed by using running clearance during implementation without affecting train running, and the separated quick changing ground magnetic sensor is simple, safe and reliable.
Description
Technical field
The present invention relates to a kind of Split quick-change ground magnetic inductor, belong to railway traffic equipment technical field.
Background technology
Along with the speed of service of China railways train improves constantly, people are also more and more higher to the requirement of rolling stock safe operation standard.For protection environment, also due to its relative safety, accuracy and reliability are high, electric locomotive is increasingly being applied in railway transportation.For more reasonably using electric locomotive, it is necessary to use ground signal to control mobile equipment.At present, the domestic vehicle-mounted neutral-section passing system being based on non-maintaining terrestrial positioning technology taked, its positioner is to adopt ground magnetic inductor as signal source, and ground magnetic inductor, as fixed mechanism, is fixed on built-in type sleeper by built-in type sleeper and securing member.Then, whole device is embedded on rail track, in order to electric locomotive receives the signal that the ground magnetic inductor being embedded in sleeper sends in the process travelled.
But, along with high ferro circuit uses ground magnetic inductor comprehensively, because damaging, the magnetic inductor that the factors such as magnetic decay cause is changed quantity and is got more and more, it is more and more prominent with the contradiction of traffic safety that it changes efficiency, and the cost of replacing also will be originally more high, greatly governs high ferro safety and development.Existing ground magnetic inductor is monoblock type magnetic inductor, and Magnet rustless steel entirety is wrapped to form magnet, is embedded by magnet in prefabricated embedded iron on sleeper, and links with embedded iron with screw, and bottom bolt is connected with sleeper.Due to magneticaction, between embedded iron and magnet, there is extremely strong magneticaction, manually magnet cannot be taken out from inserts；Another bottom connecting bolt because of with ground, bolt to be laid down and sleeper must be dismantled ability removal, waste time and energy and affect train operation.
Summary of the invention
The present invention is directed to existing overall magnetic inductor Problems existing, it is proposed to a kind of can the theory of quick-replaceable split type ground magnetic inductor, namely adopt multi-hull type Magnet, the theory of split type protective cover and spiral embedding, solve to change difficulty, the problem that magnetic decay is big；Achieve and be individually replaced, greatly reduce the cost of replacing, it is possible to use driving gap quick-replaceable, do not affect train operation.Concrete technical scheme is as follows:
Split quick-change ground magnetic inductor includes protective cover, magnet, securing member, built-in fitting and sleeper；Wherein, magnet includes Magnet and collet, and the two is bolted；Magnet is combined with built-in fitting by bolt and is connected, and prevents from getting loose by magnetic interaction；Protection cover-cap is outside magnet, by securing member and built-in fitting locking.
Further, described securing member is hinge screws.Described hinge screws is arranged on magnetic inductor both sides, through also fixed blade guard and built-in fitting.Or, built-in fitting both sides are provided with draw-in groove, and protective cover side is buckled in draw-in groove, and opposite side is by hinge screws and built-in fitting locking.
Further, magnet is square, hexagon or other symmetric polygonal.
Further, protective cover lower end is provided with sealing strip.
Further, built-in fitting outer rim and protective cover contact position are provided with sealing strip.
Further, collet is provided with pin-and-hole.
Present invention achieves independent, the quick-replaceable of ground magnetic inductor, greatly reduce the cost of replacing, driving gap can be utilized during enforcement just can to change rapidly, do not affect train operation, simple, reliable again safely.
Accompanying drawing explanation
Fig. 1 is one of present configuration schematic diagram.
Fig. 2 is the two of present configuration schematic diagram.
In figure: 1 protective cover, 2 Magnet, 3 collets, 4 hinge screws, 5 built-in fittings, 6 sleepers, 7 draw-in grooves, 8 pin-and-holes.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention will be further described.
Embodiment one
As it is shown in figure 1, Split quick-change ground magnetic inductor includes protective cover 1, magnet, hinge screws 4, built-in fitting 5 and sleeper 6；Magnet includes Magnet 2 and collet 3；Collet 3 is connected with Magnet 2 and is combined with built-in fitting 5 by screw thread；Protective cover 1 covers outside magnet, is locked by hinge screws 4 and built-in fitting 5.Magnet is square, hexagon or other symmetric polygonal.Protective cover 1 lower end is provided with sealing strip.Hinge screws 4 is arranged on magnetic inductor both sides, through also fixed blade guard 1 and built-in fitting 5.Collet 3 is provided with pin-and-hole 8.
The magnet of the present invention and protective cover 1 adopt split-type structural, collet 3 and Magnet 2 are connected formation magnet by bolt, and magnet is combined with built-in fitting 5 further through bolt, easy to loading and unloading.During use, fastening after firmly until magnet and built-in fitting 5, covered by protective cover 1, protective cover 1 and built-in fitting 5 are locked by hinge screws 4, protective cover 1 and built-in fitting 5 use sealing joint strip to seal, this kind of simple in construction safe ready.During replacing, hinge screws 4 is unloaded and extracts, take away protective cover 1, Special anti-theft tool socket is used to insert outside band geometry magnet, by pin, collet 3 is linked with box spanner, pull sleeve handle, rotated by opposite direction and magnet is progressively departed from built-in fitting 5, after screw thread all screws out, firmly magnet is together taken out together with box spanner, the magnet more renewed.
