Embodiment 1

[0072] Such as Figure 13 As shown, in this embodiment, the single turnout is a right turnout and the opening direction is the main line, the track inspection robot needs to pass along the main line, and the traffic direction of the turnout is consistent with the inspection plan (arrow direction).

[0073] The crossing method of the running part is as follows:

[0074] 1) There is a turnout area in front (the position of the running part is shown in A in the figure);

[0075] 2) The industrial computer judges that the opening direction of the turnout is consistent with the inspection direction;

[0076]3) The lifting mechanism puts down the guide wheel on the right, the translation mechanism stretches out the guide wheel, the self-locking gas spring locks, the running part moves to the left (the position of the running part is shown in B in the figure), and the right guide wheel retracts ;

[0077] 4) Enter the turnout area (the position of the running part is shown as C in...

Embodiment 2

[0080] Such as Figure 14 As shown, in this embodiment, the single-opening switch is a right-opening switch and the opening direction is the side line, the track inspection robot needs to pass along the side line, and the traffic direction of the turnout is consistent with the inspection plan (arrow direction).

[0081] The crossing method of the running part is as follows:

[0082] 1) There is a turnout area in front (the position of the running part is shown in A in the figure);

[0083] 2) The industrial computer judges that the opening direction of the turnout is consistent with the inspection direction;

[0084] 3) The lifting mechanism puts down the left guide wheel, the translation mechanism stretches out the guide wheel, the self-locking gas spring locks, the running part moves to the right (the position of the running part is shown in B in the figure), and the left guide wheel retracts ;

[0085] 4) Enter the turnout area (the position of the running part is shown ...

Embodiment 3

[0088] Such as Figure 15 As shown, in this embodiment, the single turnout is a right turnout and the opening direction is the main line, and the track inspection robot needs to pass along the side line (direction of the arrow), and the passing direction of the turnout is inconsistent with the inspection plan.

[0089] The crossing method of the running part is as follows:

[0090] 1) There is a turnout area in front (the position of the running part is shown in A in the figure);

[0091] 2) The industrial computer judges that the opening direction of the turnout is inconsistent with the inspection direction;

[0092] 3) The lifting mechanism puts down the guide wheels on both sides, the translation mechanism stretches out the left guide wheel, the self-locking gas spring locks, the running part moves to the right (the position of the running part is shown in B in the figure), and the left guide wheel turns to the alignment position (the position of the running part is shown...

Abstract

The invention relates to the field of rail transit inspection. The invention aims to provide a rail inspection robot walking part capable of adaptively crossing the turnout and a turnout crossing method, so that the problem that the rail inspection robot cannot adaptively cross the turnout when passing through a turnout zone is solved, and the rail inspection robot can smoothly pass through the turnout zone to complete an inspection plan without manual assistance or turnout switching cooperation. The inspection efficiency is fundamentally improved. According to the technical scheme, the rail inspection robot walking part capable of adaptively crossing the turnout comprises a chassis, two pairs of walking wheels arranged at the bottom of the chassis, and a power mechanism for driving the walking wheels to rotate; and the walking part is characterized in that an industrial personal computer, a structured light camera, a battery and a sensor are arranged on the chassis, and guide wheels, lifting mechanisms used for retracting and releasing the guide wheels, translation mechanisms used for driving the guide wheels to transversely move and self-locking gas springs connected with the guide wheels and the lifting mechanisms are arranged on the two sides of the chassis respectively.

Description

technical field [0001] The invention relates to the field of rail transit inspection, in particular to a track inspection robot running part and a method for crossings that can adapt to crossings. Background technique [0002] In the rail transit system, the track structure is the main structure directly bearing the train above, and its stable and reliable service state is the key to ensure the safety of the line. At present, in the daily maintenance and inspection of the track structure, most lines still require construction personnel to conduct regular inspections in the operating skylight. This manual inspection operation and maintenance method is affected by climate conditions, environmental factors, personnel quality, and sense of responsibility. Restricted by various factors, there are also disadvantages such as heavy workload, low degree of informatization, and high management costs. [0003] At present, the track inspection is developing towards the trend of intelli...
