DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0022] See Figures 1 to 4 In an embodiment of the present utility model, a measuring device for urban rail transit signal equipment includes a base 1, a first axle 2 is rotatably connected to the front end of the base 1, and steering wheels 3 are rotatably connected to both sides of the first axle 2, a second axle 4 is rotatably connected to the rear end of the base 1, and driven wheels 5 are rotatably connected to both sides of the second axle 4, and a plurality of groups of equally spaced tooth blocks 6 are fixedly connected to the outer wall of the driven wheel 5, the diameter of the steering wheel 3 is larger than that of the driven wheel 5, a rotating shaft 13 is rotatably connected to the inside of the base 1, a detection device 23 is fixedly connected to the top of the rotating shaft 13, and a signal receiver 24 fixedly connected to the rotating shaft 13 is provided on one side of the detection device 23. A fixing seat 18 is fixedly connected to the base 1, and a laser generator 19 is fixedly mounted on the fixing seat 18. A fixing frame 20 is fixedly connected to the base 1, and a photoelectric gate 22 is mounted on the fixing frame 20. A counter 21 is connected to the photoelectric gate 22. A light shielding sheet 17 is provided between the laser generator 19 and the photoelectric gate 22. A transmission assembly is installed on the second axle 4 for driving the second axle 4 to rotate synchronously with the rotating shaft 13. A reducer assembly is installed between the transmission assembly and the rotating shaft 13 for reducing the speed between the rotating shaft 13 and the second axle 4. The light shielding sheet 17 is installed on the reducer assembly.

[0023] The utility model firstly makes the base 1 tilted by setting the diameter of the steering wheel 3 larger than the driven wheel 5, and the front end of the base 1 is higher than the rear end. At this time, most of the weight of the equipment acts directly on the driven wheel 5, thereby increasing the friction between the driven wheel 5 and the road surface. At the same time, the friction between the driven wheel 5 and the road surface is further increased by setting the tooth block 6 on the outer wall of the driven wheel 5. At this time, when the base 1 moves, the driven wheel 5 rotates synchronously with the movement of the base 1, and the driven wheel 5 drives the second axle 4 to rotate. The second axle 4 drives the rotating shaft 13 to rotate through the transmission assembly and the reducer assembly. At this time, the rotating shaft 13 drives the detection device 23 and the signal receiver 24 to rotate, so that the track is detected by the signal receiver 24. The traffic signal is received and the signal strength is detected by the detection device 23. At the same time, the light shielding plate 17 is driven to reciprocate between the laser generator 19 and the photoelectric gate 22 through the reducer assembly. At the same time, the number of times the light shielding plate 17 passes the photoelectric gate 22 is counted by the setting of the counter 21. At this time, since the rotation of the rotating shaft 13 is linked with the second axle 4, the number of times the light shielding plate 17 passes the photoelectric gate 22 is positively correlated with the number of rotations of the second axle 4, and the moving distance of the equipment is positively correlated with the number of rotations of the driven wheel 5. Therefore, the number of times the light shielding plate 17 passes the photoelectric gate 22 and the moving distance of the equipment are positively correlated. Therefore, the moving distance of the equipment can be judged by observing the statistical results of the counter 21.

[0024] In one embodiment of the present invention, see Figures 1 to 4 The transmission assembly includes a transmission shaft 7 rotatably connected to the bottom of the base 1, the second axle 4 is fixedly connected to a first bevel gear 8, the transmission shaft 7 is fixedly connected to one end close to the second axle 4 with a second bevel gear 9, the first bevel gear 8 and the second bevel gear 9 are meshed with each other, and a driving shaft 10 is rotatably connected in the base 1, and a third bevel gear 11 is fixedly connected to the bottom of the driving shaft 10, and the other end of the transmission shaft 7 is fixedly connected to a fourth bevel gear 12, and the third bevel gear 11 and the fourth bevel gear 12 are meshed with each other. The transmission assembly drives the first bevel gear 8 to rotate through the second axle 4, and the first bevel gear 8 drives the transmission shaft 7 to rotate by mutual meshing with the second bevel gear 9, and the transmission shaft 7 drives the fourth bevel gear 12 to rotate, and the fourth bevel gear 12 drives the third bevel gear 11 to rotate by mutual meshing with the third bevel gear 11, and the third bevel gear 11 drives the drive shaft 10 to rotate.

[0025] In one embodiment of the present invention, see Figures 1 to 4The reducer assembly includes a second gear 15 fixedly connected to the rotating shaft 13, and the other end of the drive shaft 10 is fixedly connected to the first gear 14. The first gear 14 and the second gear 15 are meshed with each other. The number of teeth of the second gear 15 is greater than the number of teeth of the first gear 14. The second gear 15 is fixedly connected to a connecting frame 16, and the light shielding sheet 17 is fixedly connected to the connecting frame 16. The reducer assembly drives the first gear 14 to rotate through the drive shaft 10, and the first gear 14 drives the second gear 15 to rotate by meshing with the second gear 15. The gear 15 rotates, and the second gear 15 drives the rotating shaft 13 to rotate. Since the number of teeth of the second gear 15 is greater than the number of teeth of the first gear 14, and the ratio of the number of teeth of the first gear 14 to the second gear 15 is the transmission ratio, the reduction drive between the rotating shaft 13 and the second axle 4 is realized. At the same time, the second gear 15 drives the shading plate 17 to rotate synchronously through the connecting frame 16, and then drives the shading plate 17 and the rotating shaft 13 to rotate synchronously, thereby realizing the reciprocating motion of the shading plate 17 between the laser generator 19 and the photoelectric gate 22.

[0026] In one embodiment of the present invention, see Figures 1 to 4 The front end of the base 1 is rotatably connected to a support rod 25 , and the utility model tows the equipment through the setting of the support rod 25 .

[0027] In one embodiment of the present invention, see Figures 1 to 4 A battery 26 is fixedly installed at the front end of the base 1. The utility model supplies power to the electrical equipment through the setting of the battery 26, and increases the weight of the equipment through the setting of the battery 26, thereby increasing the friction between the driven wheel 5 and the road surface.
