Technical Field

The invention relates to the field of railway signals, in particular to a mounting and protecting device for a ballastless track bed transponder.

Technical Field

A transponder is a device that provides ground information to train-mounted devices, and can be roughly classified into two types: the passive transponder is provided with fixed information without a tail cable; and the active transponder is connected with the trackside equipment through a tail cable and provides variable information. The transponder is installed on a track bed in the middle of a steel rail of the ballastless track bed, and when a train passes through, the vehicle-mounted equipment reads information in the transponder to ensure driving safety.

In the use process of the transponder, foreign matters or air flow and the like driven by the high-speed running of the train can bring harm to the transponder. Particularly, the train bottom in cold regions in winter is easy to freeze, and when the train runs from a low-temperature region to a high-temperature region or the train vibrates greatly, ice blocks are easy to fall off. The fallen ice may directly impact the transponder or slide on the track bed at high speed under the action of inertia and impact the transponder, so that the transponder is damaged, and the driving safety is affected.

The condition that the transponder is impacted by ice blocks, the mounting bolt is broken, the root of the tail cable is broken, the shell of the transponder is cracked and the like can occur in the railway system in winter every year, and great potential safety hazards are brought to safe running of trains. At present, the anti-ice-block hitting capacity of the domestic ballastless track bed transponder mounting and protecting device is generally insufficient, no tail cable is used for protection, and the risk of secondary damage to the train bottom is large.

Detailed Description

In order to make the technical features, objects, and effects of the present invention more comprehensible, embodiments accompanied with figures are described below.

The installation and protection device for the ballastless track bed transponder adopts a structure that the two side surfaces are semi-wedge-shaped, the middle groove is formed, and the boss is attached to one end of the groove, the transponder is installed in the groove, and the installation and protection device can be fixed on a track bed through four holes or six holes, so that the transponder and a tail cable are effectively protected.

Fig. 1A is a schematic structural diagram of a mounting and protecting device of a ballastless track bed transponder, a groove is formed in a base 1 of the mounting and protecting device, and the transponder is fixed in the groove through a mounting hole 3.

The groove is internally designed with a drainage fabrication hole 2, so that dust accumulated at the bottom of the groove can be discharged by utilizing rainwater, and the phenomenon that the performance of the dust is influenced by interference generated on signal transmission of the transponder when the dust is accumulated, particularly when metal fine scraps are contained in the dust, is prevented.

When the train runs at a high speed, the air flow driven by the train generates impact force on the front end of the base 1, and the impact force is converted into shearing force borne by the fixing bolt 14/16. That is, when a train passes at a high speed, the fixing bolt is sheared, and the service life of the fixing bolt is shortened in the past. Therefore, the air flow channel 5 consistent with the running direction of the train is designed on the base 1 of the invention to release the air flow, the influence of the running air flow of the train on the fastening bolts 14/16 of the base is reduced, and the service life of the base is prolonged. In addition, the half wedge-shaped surface 7 can also properly reduce the impact of high-speed airflow on the base 1, namely, the shearing force borne by the fixing bolt 14/16 is reduced, and the service life of the fixing bolt is prolonged.

When the base 1 is impacted by an ice block, the impact force is converted into a shearing force borne by the fastening bolts 14/16, and when the shearing force limit of the fastening bolts is exceeded, the bolts are broken. The half wedge-shaped surface 7 is a surface mainly bearing impact and consists of two side surfaces and a middle large arc transition surface, and the large arc transition surface can uniformly transmit impact force to each part of the base 1, so that stress concentration is avoided, and the impact resistance of the base 1 is improved. This face is the structural style that the protruding both ends of centre are concave and tilt up simultaneously, consequently can play the effect of breaking ice and decompose the impact that receives, has reduced the shearing force that fixing bolt 14/16 received, and the crushed ice can be followed both sides face and moved to left and right directions simultaneously, has reduced the whole upwards operation of crushed ice and has collided the vehicle bottom and cause the risk of secondary damage.

At present, the grooving surface (reference number 6) of the fixing hole of other domestic installation protection devices is generally a vertical surface and has larger width, the larger width means that the fixing hole can be impacted by ice blocks with larger volume, and the vertical surface means that all impact force is borne and is converted into shearing force borne by the fastening bolt, so that the possibility of damaging the fastening bolt is higher. In order to solve the problem, the fixing hole slotting surface 6 of the mounting and protecting device of the ballastless track bed transponder is designed into an inclined surface, and the width of the surface is reduced as much as possible on the premise of meeting the space required by a bolt mounting tool, as shown in fig. 1A and fig. 1B. The inclined surface breaks down the impact force of the smaller volume ice, reduces the shearing force borne by the fastening bolt 14/16, and prolongs the service life of the fastening bolt.

Fig. 2 is a schematic diagram of the installation and protection device for the ballastless track bed transponder for protecting the active transponder, wherein the active transponder 8 is fixed in a groove of the base 1 through four installation holes 3, and a fastening bolt 10 is subjected to anti-loose treatment through a spring washer 11 and a flat washer 12; likewise, when the base 1 shields a passive transponder, the passive transponder is fixed in the same way as an active transponder, the only difference being that the passive transponder has no tail cable.

At present, other mounting and protecting devices in China do not protect the tail cable 9 of the active transponder, and the root of the tail cable is directly exposed outside, so that the tail cable is easy to be impacted and broken. In order to solve the problem, the groove boss 12 is designed in the mounting and protecting device of the ballastless track bed transponder, so that the root of the tail cable 9 can be protected, and the situation that the tail cable is broken due to direct impact is avoided.

Fig. 3 is a schematic bottom view of the ballastless track bed installation protection device of the present invention, and the base-to-track bed contact surface 15 is designed as a pitted surface in order to increase the friction force between the base 1 and the track bed in a state that the fastening bolt 14/16 is tightened. When the base 1 is impacted to generate displacement, reaction force is generated due to the existence of friction force, a part of impact kinetic energy is converted into friction heat energy to be released, energy directly applied to the base 1 by external impact is reduced, namely shearing force borne by the fastening bolt 2/9 is reduced, and the service life of the base can be prolonged.

At present, the mounting and protecting device in China is generally fixed by four holes, and only has one fixing mode. The mounting and protecting device for the ballastless track bed transponder has three fixing modes, and can meet the requirements of different fixing modes.

Fig. 4A is a schematic view of a first fixing mode and a second fixing mode of the ballastless track bed transponder mounting protection device of the invention: the fixing mode is the same as that of other domestic protective devices, namely the fixing is carried out through four holes on the periphery of the base 1; the fixing mode is two, the four holes on the periphery of the base 1 and the two holes in the middle are used for fixing, and compared with the fixing mode I, the fixing mode further enhances the installation firmness of the base and improves the anti-striking capacity of the base; both fixing modes carry out anti-loosening treatment on the fastening bolt 14 through the spring washer 11 and the large flat cushion 15.

Fig. 4B is a third schematic view of a fixing mode of the ballastless track bed transponder mounting protection device of the invention: the fixing is carried out through four holes on the periphery of the base 1 and two holes in the middle of the transponder, the base 1 and the transponder are simultaneously fixed through two common fastening bolts 16 in the middle at the moment, the mounting firmness of the base 1 and the transponder is enhanced, and the fastening bolts 14/16 are subjected to anti-loosening treatment through the spring washer 12 and the large flat pad 15 or the flat washer 12.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
