Description

Technical Field

[0001] The utility model belongs to the technical field of cable inspection, and in particular relates to a track elevated cable inspection device. Background Art

[0002] In the rail transit viaduct line, the 33kV power supply system is mainly used to power various rail transit facilities and equipment. Its high-voltage cables are laid along the cable support paths on both sides of the viaduct to provide stable power supply for each station along the line. In order to extend the service life of the cable and reduce the impact of sun and rain on the open-air cables, a cable sunshade is installed above the cable. The cable sunshade is an inverted L-shaped semi-enclosed structure, which together with the viaduct guardrail forms a cable sunshade corridor.

[0003] Due to the special structure of the cable sunshade corridor, maintenance personnel cannot directly see the condition of the cables under the sunshade during inspection. They need to lie on the sunshade and observe the condition of the cables under the sunshade through the gap between the sunshade and the viaduct guardrail. This inspection method has low efficiency and high workload for inspectors. It is not conducive to long-distance on-site surveys and inspections, and it is also impossible to accurately determine whether the high-voltage cables are damaged or squeezed. The inspection progress and efficiency are low. Utility Model Content

The rotating column 3 is sleeved on the output shaft of the rotating motor 2. A rotating rod 4 is disposed on one side of the rotating column 3.

[0027] Specifically, the driving mechanism includes a winding motor 5, a winding wheel 6 and a winding rope 7. The winding motor 5 is arranged on the rotating rod 4, the winding wheel 6 is sleeved on the output shaft of the winding motor 5, and one end of the winding rope 7 is connected to the winding wheel 6, and the other end is connected to the camera module.

[0028] Specifically, the camera module includes a connection block 8 , a deflection motor 9 and a wireless camera 10 . The connection block 8 is connected to the winding rope 7 , the deflection motor 9 is arranged on the connection block 8 , and the wireless camera 10 is connected to the output shaft of the deflection motor 9 .

[0029] Specifically, an opening 11 is provided at one end of the rotating rod 4 away from the vehicle body 1 , and the winding rope 7 is connected to the connecting block 8 through the opening 11 .

[0030] Specifically, it also includes a guide rod that can slide up and down and is foldable, which is arranged at the end of the rotating rod 4 away from the vehicle body 1. The guide rod is provided with a guide groove 12, which is fitly connected with the end of the rotating rod 4 away from the vehicle body 1, and the guide rod can slide up and down through the guide groove 12; the guide rod includes a first sub-guide rod 13, and the connecting block 8 is fixed at the lower end of the first sub-guide rod 13.

[0031] In one embodiment, the guide rod also includes a second sub-guide rod 14, and the upper end of the first sub-guide rod 13 is provided with a hinge shaft 15 and a connecting magnet 16. The first sub-guide rod 13 is hinged to the second sub-guide rod 14 through the hinge shaft 15, and is connected to the second sub-guide rod 14 through the connecting magnet 16.

[0032] In one embodiment, the guide rod is a retractable sleeve, which is arranged at the end of the rotating rod 4 away from the vehicle body 1. The sleeve is provided with a guide groove, which is fitly connected to the end of the rotating rod 4 away from the vehicle body 1; the connecting block 8 is fixed at the lower end of the sleeve.

[0033] In one of the embodiments, a communication module (not shown in the figure) is further included, which is wirelessly connected to the wireless camera and the external mobile terminal respectively, and sends the content captured by the wireless camera to the mobile terminal for the staff to view.

The connection method between the start buttons and the rotating motor, the winding motor and the wireless camera is prior art and will not be repeated here.

[0035] The following is an explanation of the specific implementation process:

[0036] When the track overhead cable inspection device provided by this embodiment is working on site, the rotating motor works so that the rotating column drives the rotating rod to move above the cable sunshade beside the vehicle body, and the camera module is located inside the cable sunshade. When the guide rod is in a folded state, the inspector manually lifts up the second sub-guide rod so that the second sub-guide rod is connected to the first sub-guide rod through a hinge shaft and a connecting magnet. When the second sub-guide rod is connected to the first sub-guide rod to form a guide rod, the winding motor works to drive the winding wheel to rotate and release the winding rope. The connecting block drops due to gravity, driving the wireless camera to drop and approach the high-voltage cable at the bottom of the track overhead. The deflection motor works to control the wireless camera to rotate up and down to collect the high-voltage cable conditions at different angles.

[0037] When it is necessary to collect cable conditions at different heights, the winding motor drives the winding wheel to retract the winding rope, and the connecting block and the guide rod rise to observe the high-voltage cables at other heights.

[0038] When the rail overhead cable inspection device finishes its work, the inspector manually folds the second sub-guide rod, the winding motor drives the winding wheel to retract the winding rope, the connecting block and the first guide rod and the second guide rod all rise, and the rotating motor drives the rotating rod to move to the front or rear of the vehicle body for easy storage.

[0039] The rail overhead cable inspection device provided in this embodiment can realize inspection and observation of high-voltage cables at different heights, and can also control the wireless camera to adjust different observation angles through the deflection motor, thereby improving the inspection efficiency and inspection quality of high-voltage cables.

[0040] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
