Description

Technical Field

[0001] The utility model relates to the technical field of subway transponders, in particular to a subway transponder based on communication technology. Background Art

[0002] When the subway stops, it can accurately locate the parking position, which requires the use of a transponder. The transponder is connected to the ground electronic unit through a cable and can send data messages transmitted by LEU in real time. When the train passes over the active transponder, the active transponder receives the electromagnetic energy emitted by the on-board antenna and converts it into electrical energy, which makes the transmitting circuit in the ground transponder work and sends the data transmitted by LEU to the active transponder in real time until the power disappears.

[0003] The existing method for adjusting the height of the four corners of the transponder device to the track surface is to manually add or remove insulating spacers between the bottom of the transponder device and the fiberglass plate to ensure that the difference in the distance from the two corners on the same side to the track is ≤9mm when installed horizontally and ≤15mm when installed vertically. The above-mentioned manual adjustment method of adding spacers requires repeated removal of the strain gauge device to add or remove spacers to adjust the height of the strain gauge device to the required range. This adjustment process is cumbersome and time-consuming. In view of this, a subway transponder based on communication technology is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-3 The utility model provides a new technical solution: a subway transponder based on communication technology, comprising two pins 1, a mounting plate 2 is fixedly mounted on the upper surface of the two pins 1, and a transponder body 3 is provided on the upper surface of the mounting plate 2;

[0027] Among them, an installation mechanism is provided on the transponder body 3, which includes two hollow columns 4, two slide grooves 5, four first springs 6, four fixing plates 7, four rings 8, four round holes 9, four round balls 10, two fixing columns 11, six card slots 12, multiple gaskets 13, two piston rods 14, two second springs 15 and two dampers 16.

[0028] Furthermore, two hollow pillars 4 are fixedly mounted on the lower surface of the transponder body 3, and two slide grooves 5 are respectively opened on the outer surfaces of the two hollow pillars 4;

[0029] Furthermore, four circular holes 9 are respectively opened on the inner surfaces of the two chutes 5 , and four round balls 10 are respectively arranged on the inner surfaces of the four circular holes 9 .

[0030] Furthermore, four first springs 6 are respectively fixedly mounted on the inner surfaces of the two chutes 5, and four fixing plates 7 are respectively fixedly mounted on the lower ends of the four first springs 6, and the lower surfaces of the four fixing plates 7 are all inclined.

[0031] The two rings 8 are fixedly mounted on the outer surfaces of the four fixing plates 7 , and the two rings 8 are slidably sleeved on the inner surfaces of the two sliding grooves 5 .

[0032] Furthermore, the two dampers 16 are respectively fixedly mounted on the inner surface of the mounting plate 2 , and the two second springs 15 are respectively fixedly mounted on the upper surfaces of the two dampers 16 .

[0033] The two piston rods 14 are fixedly mounted on the upper ends of the two second springs 15 , and the two piston rods 14 are slidably sleeved on the inner surfaces of the two dampers 16 .

[0034] Furthermore, two fixing columns 11 are fixedly mounted on the upper surfaces of the two piston rods 14, and six slots 12 are respectively opened on the outer surfaces of the two fixing columns 11;

[0035] Wherein, a plurality of gaskets 13 are respectively arranged on the outer surface of the fixing column 11;

[0036] When the subway transponder based on communication technology is in use, an upward thrust is applied to the circular ring 8 to make it move to the upper left, and at the same time, the circular ring 8 drives the two fixed plates 7 fixed on the inner surface to move upward. At this time, the two fixed plates 7 apply pressure to the two first springs 6 fixed on the upper surface to cause them to contract. At this time, the two fixed plates 7 no longer block the two circular holes 9, that is, they do not limit the two round balls 10 set in the two circular holes 9. At this time, the hollow column 4 fixedly installed on the lower surface of the transponder body 3 is inserted into the outer surface of the two fixed columns 11, and the two circular holes 9 opened on the outer surface of the hollow column 4 are aligned with the card groove 12 opened on the outer surface of the fixed column 11. At this time, an upward thrust is no longer applied to the circular ring 8, and the two first springs 6 are no longer under force. At this time, the two first springs 6 expand, and the two first springs 6 apply a downward thrust to the two fixed plates 7 fixed at the lower end, causing them to slide downward in the inner wall of the slide groove 5. At this time, the inclined surfaces of the two fixed plates 7 collide Two balls 10 are provided, and thrust is applied to the two balls 10 on opposite surfaces, so that the two balls 10 move toward opposite surfaces and are engaged in the card slots 12 provided on the outer surface of the fixing column 11 for fixation. At this time, the installation is completed. The installation height of the transponder body 3 can be adjusted by sleeved with multiple gaskets 13 on the outer surface of the fixing column 11, and the track is driven to vibrate when the subway passes by. At this time, the pin 1 inserted in the bottom surface is driven to vibrate, and the pin 1 transmits this force to the mounting plate 2. At this time, the damper 16 in the mounting plate 2 moves upward on the outer surface of the piston rod 14. The damper 16 in the utility model is a hydraulic damper. The hydraulic damper consumes energy through the damping oil and the damping hole, thereby slowing down or stopping the process of mechanical movement, thereby forming a certain buffer to prevent the force from being transmitted to the transponder body 3 and causing shaking. At the same time as the damper 16 moves upward, pressure is applied to the second spring 15, and a certain buffer is formed by the elastic potential energy of the second spring 15 itself.

[0037] The subway transponder based on communication technology can quickly disassemble and assemble the transponder body 3 by snapping together, and can be frequently disassembled and assembled in this way to adjust the installation height of the transponder body 3, which is more convenient. In addition, the subway transponder based on communication technology can slow down the force transmitted to the transponder body 3 through the damper 16, the second spring 15 and the piston rod 14 when the subway passes over the track, thereby reducing its shaking, thereby improving the stability of the transponder body 3 after installation, and avoiding the loosening of the components of the transponder body 3 due to frequent shaking.

[0038] Working principle: When the subway transponder based on communication technology is in use, an upward thrust is applied to the circular ring 8 to make it move to the upper left, and at the same time, the circular ring 8 drives the two fixed plates 7 fixed on the inner surface to move upward. At this time, the two fixed plates 7 apply pressure to the two first springs 6 fixed on the upper surface, causing them to contract. At this time, the two fixed plates 7 no longer block the two circular holes 9, that is, they no longer limit the two round balls 10 set in the two circular holes 9. At this time, the hollow column 4 fixedly installed on the lower surface of the transponder body 3 is inserted into the outer surface of the two fixed columns 11, and the two circular holes 9 opened on the outer surface of the hollow column 4 are aligned with the card groove 12 opened on the outer surface of the fixed column 11. At this time, an upward thrust is no longer applied to the circular ring 8, and the two first springs 6 are no longer under force. At this time, the two first springs 6 expand, and the two first springs 6 apply a downward thrust to the two fixed plates 7 fixed at the lower end, causing them to slide downward in the inner wall of the slide groove 5. At this time, the inclined portions of the two fixed plates 7 The two balls 10 are hit by the two surfaces, and a thrust is applied to the two balls 10 relative to the surfaces, so that the two balls 10 move toward the opposite surfaces and are fixed in the slots 12 provided on the outer surface of the fixing column 11. At this time, the installation is completed. The installation height of the transponder body 3 can be adjusted by sleeved with multiple gaskets 13 on the outer surface of the fixing column 11, and the track is driven to vibrate when the subway passes by, and the pin 1 inserted in the bottom surface is driven to vibrate. The pin 1 transmits this part of the force to the mounting plate 2. At this time, the damper 16 in the mounting plate 2 moves upward on the outer surface of the piston rod 14. The damper 16 in the utility model is a hydraulic damper. The hydraulic damper consumes energy through the damping oil and the damping hole, thereby slowing down or stopping the process of mechanical movement, and then forming a certain buffer to prevent the force from being transmitted to the transponder body 3 and causing shaking, and while the damper 16 moves upward, it applies pressure to the second spring 15, and a certain buffer is formed by the elastic potential energy of the second spring 15 itself.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
