[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figures 1 to 6 The utility model describes the above technical solution in detail through the following embodiments:
[0027] A track detection device for railway engineering maintenance includes a detection seat 1, on which two detection members 2 are centrally symmetrically arranged, one side of the detection member 2 is provided with a first detection wheel 21, and the other side of the detection member 2 is slidably provided with a second detection wheel 22. Because the two detection members 2 are centrally symmetrically arranged on the detection seat 1, the first detection wheel 21 and the second detection wheel 22 on the two detection members 2 are also centrally symmetrically arranged on the detection seat 1, so that the center of gravity of the detection seat 1 remains stable, thereby ensuring the accuracy of detecting the spacing of the tracks. A detection unit is provided between the second detection wheel 22 and the detection member 2, and the detection unit is used to detect the distance between the second detection wheel 22 and the first detection wheel 21, so that the spacing of the tracks is detected through the cooperation of the first detection wheel 21, the second detection wheel 22 and the detection unit. For detection, a sprayer 3 is also provided on the detection seat 1, and two spray pipes 31 are symmetrically provided on the output end of the sprayer 3, and a spray nozzle 32 is provided on the output end of the spray pipe 31, and a trigger switch 33 is provided on the spray pipe 31. A trigger unit is provided between the trigger switch 33 and the detection member 2, and the trigger unit is used to start the sprayer 3 when the distance between the second detection wheel 22 and the first detection wheel 21 changes, so that when the distance between the second detection wheel 22 and the first detection wheel 21 changes, the sprayer 3 is started by the cooperation of the trigger switch 33 and the trigger unit, so that the sprayer 3 transports the paint to the spray nozzle 32 through the spray pipe 31, and then the paint sprayed by the spray nozzle 32 marks the fault point on the track, so that the staff can quickly and accurately find the fault point according to the paint on the track for repair.
[0028] like Figures 4 to 6As shown, the detection unit includes a laser rangefinder 4 and a detection rod 41. A detection cavity is provided inside the detection member 2. The laser rangefinder 4 is arranged on a side of the detection cavity close to the first detection wheel 21. The detection rod 41 is slidably arranged on a side of the detection cavity close to the second detection wheel 22. The rod end of the detection rod 41 close to the second detection wheel 22 extends to the outside of the detection member 2. The second detection wheel 22 is arranged on the rod end of the detection rod 41 extending to the outside of the detection member 2. An elastic unit is provided between the detection rod 41 and the laser rangefinder 4, so that the first detection wheel 21 and the second detection wheel 22 can detect the spacing of the tracks through the cooperation of the laser rangefinder 4 and the detection rod 41.
[0029] like Figures 4 to 6 As shown, the elastic unit includes a support block 42, a detection block 43 and a detection spring 44. The support block 42 is arranged between the laser rangefinder 4 and the detection rod 41. A through hole is provided on the support block 42, and the through hole is used for the laser detection line of the laser rangefinder 4 to pass through. The detection block 43 is arranged on the rod end of the detection rod 41 located inside the detection member 2. The detection spring 44 is arranged between the detection block 43 and the support block 42, so that the first detection wheel 21 and the second detection wheel 22 are in contact with the two tracks through the cooperation of the support block 42, the detection block 43 and the detection spring 44, and then the spacing of the tracks is detected through the cooperation of the laser rangefinder 4 and the detection rod 41.
[0030] like Figures 1 to 3 As shown, the trigger unit includes a trigger seat 5 and a trigger rod 51. The trigger seat 5 is slidably arranged on the rod body extending from the detection rod 41 to the outside of the detection member 2. A locking bolt 52 is rotatably arranged on the trigger seat 5. The trigger rod 51 is arranged on the trigger seat 5. One end of the trigger rod 51 abuts against the trigger end of the trigger switch 33. Therefore, when the distance between the second detection wheel 22 and the first detection wheel 21 changes, the sprayer 3 is started by the trigger seat 5, the trigger rod 51 and the trigger switch 33.
[0031] like Figure 3 As shown, the rod end of the trigger rod 51 that abuts against the trigger end of the trigger switch 33 and the trigger end of the trigger switch 33 are both trapezoidal structures, so that the connection between the rod end of the trigger rod 51 and the trigger end of the trigger switch 33 is sufficiently stable, and at the same time, when the distance between the second detection wheel 22 and the first detection wheel 21 changes, the rod end of the trigger rod 51 can be separated from the trigger end of the trigger switch 33 more quickly.
[0032] like Figure 1 As shown, the spray nozzle 32 is arranged on the spray pipe 31 at an angle, so as to ensure that the spray nozzle 32 sprays the paint onto the track.
[0033] like Figure 1As shown, the spraying machine 3 is provided with a signal module 11 , so that the position of the fault point is recorded through the signal module 11 , and the position information is transmitted to the background through the signal module 11 .
[0034] Working principle: first, push the second detection wheel 22 on the detection member 2 toward the direction of the first detection wheel 21, so that the second detection wheel 22 drives the detection block 43 connected to the detection rod 41 to squeeze the detection spring 44 toward the support block 42 for deformation, and then the second detection wheel 22 and the first detection wheel 21 are respectively pressed against two tracks, so that the detection block 43 drives the second detection wheel 22 connected to the detection rod 41 to press against one of the tracks under the elastic force of the detection spring 44 to restore the deformation, and at the same time, the support block 42 drives the first detection wheel 21 connected to the detection member 2 to press against the other track under the elastic force of the detection spring 44 to restore the deformation, and then move the trigger seat 5 on the detection rod 41 to the position where the rod end of the trigger rod 51 presses against the trigger end of the trigger switch 33, and finally lock the trigger seat 5 on the detection rod 41 by the locking bolt 52.
[0035] When the second detection wheel 22 and the first detection wheel 21 roll to the point where the spacing between the track changes, the spacing between the second detection wheel 22 and the first detection wheel 21 will change synchronously. When the spacing between the second detection wheel 22 and the first detection wheel 21 changes, the spacing between the detection rod 41 and the detection member 2 will change synchronously. At this time, the spacing between the detection block 43 connected to the detection rod 41 and the laser rangefinder 4 will change synchronously, so that the data measured by the laser rangefinder 4 and the detection block 43 changes, and then the position information of the fault point is transmitted to the background through the signal module 11. At the same time, when the spacing between the detection rod 41 and the detection member 2 changes, the detection rod 41 will drive the rod end of the trigger rod 51 on the trigger seat 5 to disengage from the trigger end position of the trigger switch 33, so that the trigger switch 33 starts the sprayer 3, and at the same time, the sprayer 3 transports the paint to the spray nozzle 32 through the spray pipe 31, so that the paint sprayed by the spray nozzle 32 marks the fault point on the track, which is convenient for the staff to quickly and accurately find the fault point according to the paint on the track for repair.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
