Description

Technical Field

[0001] The utility model belongs to the field of track measuring instruments, and particularly relates to a special track gauge for F track of medium and low speed maglev lines. Background Art

[0002] With the continuous development of maglev rail transit in China, the demand for related supporting products and equipment is also increasing. "Gauge" is an important factor affecting track traffic safety and needs to be detected both in the initial construction and operation and maintenance of the track. The train track of medium and low speed maglev lines is F track. Since the structure of F track is quite different from that of traditional tracks, traditional track gauges are not suitable for detecting the gauge of F track. Therefore, tools such as string boxes, steel straight rulers, tape measures and spirit levels are mainly used to measure the gauge, level and elevation values of F track. Since they are not special measuring instruments, the measuring efficiency is not only low, but also the data accuracy is difficult to guarantee. And ordinary spirit levels cannot effectively measure whether the horizontal superelevation of the track curve is normal. To better meet the gauge detection requirements of F track, a track gauge suitable for F track of medium and low speed maglev lines is urgently needed. Summary of the Utility Model

[0003] To overcome the deficiencies and existing problems of the prior art and better meet the detection requirements of F track, the utility model provides a special track gauge for F track of medium and low speed maglev lines.

Detailed implementation mode

[0022] For the convenience of understanding by those skilled in the art, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0023] As Figure 1 、 2 shown, a special track gauge for F - rail of medium - and low - speed maglev lines includes a body of the ruler 100. At both ends of the bottom surface of the body of the ruler 100, there are support blocks 110. The support blocks 110 are used to abut against the inner side of the step surface at the top of the F - rail to keep the body of the ruler 100 of the track gauge stable. The support blocks 110 are made of magnetic material and can be adsorbed on the track during use to reduce the occurrence of displacement and further improve stability. An abutting block 120 fixed to the body of the ruler 100 is provided on the inner side of one support block 110. The abutting block 120 is used to abut against the inner side of one F - rail on the track. A measuring block 130 is provided on the inner side of the other support block 110. The measuring block 130 is connected with a toggling handle 140 through a pull rod 141. By toggling the toggling handle 140, the displacement of the measuring block 130 can be controlled. The measuring block 130 is used to abut against the inner side of the other F - rail on the track.

[0024] As Figure 2 、 4As shown, the pull rod 141 is connected with a reset mechanism 160. The reset mechanism 160 includes a spring 162 sleeved on the pull rod 141. A limit plate 161 is arranged inside the ruler body 100. The two ends of the spring 162 respectively abut against the limit plate 161 and the measuring block 130. When the handle 140 is toggled, the measuring block 130 moves towards the abutting block 120, and the distance between the abutting block 120 and the measuring block 130 decreases, which is convenient for placing the track gauge on the track. After the track gauge is placed well, the abutting block abuts against the inner side of one F rail on the track. When the handle 140 is released, the spring 162 will push the measuring block 130 away from the abutting block 120, so that the measuring block 130 abuts against the inner side of the other F rail on the track, realizing the measurement of the gauge. A handle 220 is arranged at the top of the ruler body 100. The middle part of the handle 140 is hinged to the inner side of the handle 220. One end of the handle 140 is connected with the pull rod 141. The handle 220 is convenient for lifting and placing the track gauge and also convenient for toggling the handle 140.

[0025] As Figure 2 , 3 shown, the measuring block 130 is also connected with a scale 150. When the measuring block 130 displaces, the scale 150 will displace following the measuring block 130. A reading window 170 corresponding to the scale 150 is arranged on the ruler body 100. The reading window 170 corresponds to the position of the scale 150. A convex lens is arranged inside the reading window 170, which is convenient for observing the value. A marking line 171 is arranged on the reading window 170. The reading window 170 is connected with a marking line calibration mechanism 180. The marking line calibration mechanism 180 includes two adjusting screws 181 respectively arranged at both ends of the reading window 170. A connecting line 182 is connected between the two adjusting screws 181. The connecting line 182 is connected with the marking line 171. By rotating the two adjusting screws 181, the position of the marking line 171 can be controlled, which is convenient for calibrating the marking line 171 and reducing the measurement error. After the marking line 171 is calibrated, toggle the handle 140 to make the measuring block 130 and the abutting block 120 respectively abut against the inner sides of the two F rails on the track. The gauge measurement is realized by observing the corresponding value between the marking line 171 and the scale 150. The ends of the two adjusting screws 181 are embedded in the side wall of the ruler body 100, and screw slots are arranged on the end faces, so that the adjusting screws 181 can only be screwed by a screwdriver and will not rotate due to accidental movement or other situations, ensuring the stability of the marking line 171.

[0026] As Figure 2 , 5As shown, a numerical rotation column 190 and a telescopic level base 200 are further provided at the top of the scale body 100. The outer wall of the numerical rotation column 190 is provided with threads, and a numerical value is provided at the top of the numerical rotation column 190. A protective shell 191 is sleeved outside the numerical rotation column 190, and a pointer is provided at the upper end of the protective shell 191. When the numerical rotation column 190 rotates, the change amount of the numerical value can be recorded through the pointer to measure the superelevation value of the track. A level bubble 201 is provided on the telescopic level base 200. One end of the telescopic level base 200 is in threaded cooperation, and the other end is hinged to the scale body 100. An elastic telescopic head 202 is provided at the end of the telescopic level base 200, and the elastic telescopic head 202 is in threaded cooperation with the threads on the outer wall of the numerical rotation column 190. When the numerical rotation column 190 rotates, the threads drive the elastic telescopic head 202 to move up and down, causing the telescopic level base 200 to tilt, so that the level bubble 201 can be adjusted to the horizontal state to assist in measuring the horizontal superelevation value of the track.

[0027] As Figure 2 , 5 , as shown in FIGS. 6, the numerical rotation column 190 is further connected with a locking drive mechanism 210. The locking drive mechanism 210 includes a drive knob 211. The drive knob 211 is connected with a worm 212. A worm gear 192 matched with the worm 212 is provided on the numerical rotation column 190. By rotating the drive knob 211, the rotation of the numerical rotation column 190 can be controlled. The worm structure is convenient for accurately adjusting the rotation amount of the numerical rotation column 190. At the same time, only by rotating the drive knob 211 can the rotation of the numerical rotation column 190 be controlled, improving the stability of the numerical rotation column 190. The connection end 213 of the worm 212 for connecting the drive knob 211 is polygonal. A connection cavity 214 matched with the connection end 213 is provided on one side of the drive knob 211. A circular cavity 215 extends in the connection cavity 214, and the circular cavity 215 can accommodate the connection end 213. When it is necessary to drive the numerical rotation column to rotate through the worm 212, the drive knob 211 is pulled outwards to make the connection cavity 214 cooperate with the connection end 213, and then the worm 212 can be driven to rotate. When rotation is not required, the drive knob 211 is pushed towards the worm 212 to make the circular cavity 215 sleeved on the connection end 213, testing that the drive knob 211 cannot drive the worm 212 to rotate, realizing the locking function and preventing the numerical knob from rotating due to misoperation.

[0028] The above embodiments are the preferred implementation manners of the present invention, and are not intended to limit the present invention. Without departing from the inventive concept of the present invention, any obvious replacement is within the protection scope of the present invention.
