Description
TECHNICAL FIELD
[0001] The utility model belongs to transportation track horizontal detection technical field especially relates to a coal mine auxiliary transportation track horizontal difference detection device. BACKGROUND
[0002] In the process of coal mining, the coal needs to be transported in the mining area to realize the transportation of the coal in the mining area. Specifically, the coal needs to be transported to a specific area for processing after being transported from the underground to the surface. Therefore, in the actual production process, tracks need to be laid in the mining area to facilitate the transportation of the coal.
[0003] After laying the tracks, the tracks need to be measured, including the levelness, slope, track spacing, and flatness between the tracks. This testing method improves the stability of the tracks and ensures the stability of the subsequent trucks running on the tracks.
[0004] Among them, the horizontal difference detection is one of the important projects in the above detection projects, which judges the levelness of the track laying through horizontal difference detection. The current detection method is that the operator pushes the track detector to walk on the track. The detection principle is to measure the levelness of the track by the levelness measuring instrument on the detector, and the levelness difference between the levelness of the track and the standard level is obtained after calculation.
[0005] However, in the actual work process, the length of the laid track is often large, especially the straight part of the track. In the face of long track measurement, the above measurement method is obviously low in efficiency. Therefore, after laying the track, the operator needs to push the walking frame on the measuring instrument to run long distances on the track for measurement. At the same time, the tracks in the mining area are often track groups, especially in large mining areas. Therefore, it is obvious that this measurement method can only be used for tracks with small length and quantity. In the face of long track group measurement, the measurement workload is very large.
[0006] Therefore, in the actual work process, if a measurement device that automatically walks on the track is used, not only the labor intensity of the measurement work can be greatly reduced, but also the measurement efficiency can be significantly improved. INVENTION CONTENTS

[0040] Example 1
[0041] like Figures 1-6 As shown, a coal mine auxiliary transportation track level difference detection device includes two track-walking mechanisms that roll and move on two separate tracks. During operation, the two track-walking mechanisms move along the tracks to perform the detection.
[0042] The track walking mechanism includes a walking frame 1, which has the following shape: the walking frame 1 includes a U-shaped part 11, and a track wheel active walking structure 2 that rolls at the top of the track is installed on the U-shaped part 11.
[0043] Specifically, the track wheel driving walking structure 2 comprises a driving track wheel 21 rotatably connected in the U-shaped part 11 (one end of the driving track wheel 21 is rotatably connected to the U-shaped part 11 through an axle), and a track wheel groove is formed in the driving track wheel 21 to match the track. Meanwhile, a motor 22 for driving the driving track wheel 21 is installed at the side position of the U-shaped part 11.
[0044] Specifically, the output shaft of the motor 22 is fixedly installed at the other side of the driving track wheel 21, and the output shaft of the motor 22 is rotatably connected to the U-shaped part 11.
[0045] Both ends of the U-shaped part 11 are integrally formed with side frames 12 (the shape of the side frame 12 is L-shaped), and a clamping wheel structure 3 is installed on each side frame 12 to clamp the side position of the track. Specifically, the clamping wheel structure 3 comprises a clamping wheel arm 32 hingedly connected at the bottom position of the side frame 12, and a driving motor 31 for driving the clamping wheel arm 32 to flip is installed at the side position of the side frame 12 (the hinging mode is that a hinge hole is formed at the bottom of the side frame 12, one side of the clamping wheel arm is hingedly connected through a pin shaft, the other side of the side frame 12 is fixedly connected with a mounting seat, and the output shaft of the driving motor 31 is rotatably connected to the side frame 12 and fixedly connected to the other side of the clamping wheel arm).
[0046] The inner end of the clamping wheel arm is rotatably connected with a clamping wheel 31 abutting and rolling at the side position of the track. Specifically, the top and bottom of the clamping wheel 31 arm are rotatably connected with the clamping wheel 31.
[0047] During operation, the track wheel driving walking structure 2 is installed on the track in the following manner: first, the track wheel groove on the driving track wheel 21 is clamped into the track, then the driving motor 31 is turned on, and under the driving of the driving motor 31, the two clamping wheel 31 arms are flipped to clamp the clamping wheel 31 vertically on the side wall of the track. Under the clamping cooperation of the two clamping wheel 31 arms, the posture of the track wheel driving walking structure 2 is guaranteed to be perpendicular to the track, and high stability is achieved during walking. Specifically, during walking, the driving track wheel 21 is driven by the motor 22 to rub against the track, and the clamping wheel 31 cooperates to keep the track wheel driving walking structure 2 stable during walking.
[0048] The above structure realizes measurement in the mode of automatically walking on the track, which effectively improves the measurement efficiency, and the operator does not need to manually push the measurement during the measurement process, but only needs to follow the whole device (such as the operator can ride the track trolley). In this way, the detection efficiency is greatly improved, especially for the measurement of a large number of track groups with large length, which greatly reduces the measurement workload.
[0049] During the measurement, the level detector 6 for measuring the track level is installed on the walking frame 1 in the manner disclosed in the prior art; the level detector 6 is a level meter commonly used for track level measurement in the prior art. The data measured by the level meter realizes the measurement of the track level and calculates the horizontal difference between the track and the horizontal plane. In this way, accurate and rapid measurement is realized.
[0050] Embodiment 2
[0051] As shown in the drawings, the present embodiment is based on the structure of Embodiment 1, and in order to monitor the difference in level between the two tracks, two laser warning target mechanisms are installed between the track walking mechanisms, which warn the level between the two tracks through the track walking mechanisms. Figures 1-6
[0052] Specifically, the laser warning target mechanism includes a fixed sleeve rod 51 installed at the top of each walking frame 1 (the outer end of the fixed sleeve rod 51 is fixedly installed by bolts), and a telescopic rod 52 is slidably connected in the fixed sleeve rod 51 (a telescopic rod 52 cavity is formed in the fixed sleeve rod 51). The telescopic rod 52 is hinged by a hinge structure.
[0053] Specifically, the laser warning target mechanism further includes a laser lamp structure installed at the top of the rear fixed sleeve rod 51 (the laser lamp structure includes a bracket 54, and a laser lamp 55 emitting laser towards the target structure is installed on the bracket 54).
[0054] Correspondingly, the laser warning target mechanism further includes a target structure installed at the top of the other fixed sleeve rod 51 and cooperating with the laser lamp structure. The target structure includes a target plate 53 cooperating with the laser lamp, and a target plate bracket is installed at the bottom of the target plate 53.
[0055] The hinge way is that the hinge structure includes a hinge tongue plate A fixedly connected at the end of one side of the telescopic rod 52, and the hinge structure further includes a hinge port formed on the other side of the telescopic rod 52, and the hinge tongue plate A is hingedly connected in the hinge port by a pin shaft.
[0056] In the working process, when the whole device runs between the tracks, when the levelness difference of the two sides of the track is large (that is, the top surfaces of the two sides of the track are not on the same horizontal plane, and there is a height difference), at this time, the track walking mechanism of the two sides is still unobstructed due to the height difference, and the track walking mechanism of the two sides is still unobstructed under the cooperation of the hinge structure (the height difference causes the hinge rotation and telescopic sliding between the telescopic rods 52), but the height position between the laser lamp 55 installed on one side of the track walking mechanism and the target plate 53 on the other side changes, at this time, the light spot of the laser lamp on the target plate 53 shakes violently, prompting the operator that the levelness difference between the two sides of the track is large, at this time, the operator stops the whole device, and measures through the auxiliary level (under normal circumstances, the two sides of the track are on the same horizontal plane, which facilitates the stability of the coal mine transported on the track), through the above-mentioned way, the unevenness of the track can be more directly warned during the measurement process.
[0057] According to the existing mode, the camera 6 is installed on the walking frame 1. The camera 6 realizes the background monitoring of the movement measurement process.
[0058] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the person skilled in the art within the scope of the present application should also belong to the protection scope of the present application.
