Description

Technical Field

[0001] The invention belongs to the technical field of electric power maintenance equipment, and in particular relates to a mobile mechanism for visual cable inspection. Background Art

[0002] Cables are used as transmission channels for electricity. With the application of electricity, they are widely used. However, they will inevitably age, become damaged, and be damaged by external objects during use. Therefore, it is necessary to monitor and grasp the operation of cable lines and all ancillary equipment, and promptly discover and eliminate abnormalities and defects in cable lines and all ancillary equipment to prevent accidents. At this time, a cable visualization inspection device with a mobile mechanism is needed.

[0003] The angle of the inspection equipment on the existing mobile mechanism for cable visual inspection is also relatively fixed, and the horizontal inspection angle of the inspection equipment cannot be freely adjusted, which makes it difficult for the equipment to conduct detailed inspections on the cables on both sides; and the height of the inspection equipment in the mobile mechanism for cable visual inspection device is usually not freely adjustable, and the inspection equipment with a fixed height often cannot more comprehensively inspect cables at different heights, thereby reducing the use effect of the mobile mechanism for cable visual inspection; at the same time, the existing mobile mechanism for cable visual inspection usually only drives the entire mobile mechanism to move through the driving wheels, and when the mobile mechanism turns, it is easy to cause the mobile mechanism to overturn due to unstable center of gravity, thereby reducing the stability of the mobile mechanism for cable visual inspection during use. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a mobile mechanism for visual cable inspection.

[0005] The technical solution adopted to solve the above technical problems is: a mobile mechanism for visual cable inspection, including a bottom bin as an installation carrier, a top bin installed on the top of the bottom bin, a lifting mechanism is arranged at the middle position inside the bottom bin, a patrol mechanism is arranged at the top of the lifting mechanism, a linkage mechanism cooperating with the lifting mechanism is arranged at the middle position inside the bottom bin, and support mechanisms cooperating with the linkage mechanism are arranged at both ends inside the bottom bin, a cover plate is installed on one side of the top of the bottom bin, a second camera is installed at the middle position of the top of the cover plate, a control panel is installed on the top of the cover plate, traveling wheels are arranged at the four corners of the bottom of the bottom bin, a battery is installed on the side of the bottom bin away from the cover plate, and an installation cylinder cooperating with the second camera is installed at the middle position of the bottom of the top bin close to the cover plate.

[0006] Furthermore, the lifting mechanism includes a mounting plate installed at the middle position inside the bottom bin, a connecting bearing is installed at the middle position of the top of the mounting plate, and the inner ring of the connecting bearing is installed with an external threaded tube, the outer thread of the external threaded tube is provided with an internal threaded tube, a driving assembly for driving the external threaded tube to rotate is provided on one side of the top of the mounting plate, and a through hole compatible with the internal threaded tube is opened at the middle position of the top of the top bin.

[0007] Through the above technical solution, the driving component is controlled to drive the external threaded pipe to rotate clockwise, and the thread effect is used to force the internal threaded pipe outside the external threaded pipe to slowly rise, thereby driving the inspection mechanism at the top of the internal threaded pipe to rise together, thereby helping to expand the inspection range of the inspection mechanism.

[0008] Furthermore, the drive assembly includes a first servo motor located on one side of the top of the mounting plate, the outer side of the external threaded tube extends to the bottom of the mounting plate and is equipped with a driven gear, and the output shaft of the first servo motor extends to the bottom of the mounting plate and is equipped with a driving gear that meshes with the driven gear.

[0009] Through the above technical solution, the first servo motor is controlled to drive the driving gear at the bottom of the mounting plate to rotate stably, and the transmission of the driving gear and the driven gear is used to drive the external threaded tube fixedly connected to the inner ring of the connecting bearing to rotate stably, so that the internal threaded tube outside the external threaded tube can slowly rise.

[0010] Furthermore, a limiting slide bar is symmetrically installed on the outer side of the internal threaded tube, and a limiting groove matched with the limiting slide bar is symmetrically opened on the inner wall of the through hole.

[0011] Through the above technical solution, during the lifting process of the internal threaded pipe, the limiting slide bar on the outside of the internal threaded pipe keeps sliding in the limiting groove, which helps to improve the stability of the internal threaded pipe during the lifting process.

[0012] Furthermore, the inspection mechanism includes a motor bin located at the top of the internal threaded tube, a second servo motor is installed at the center position inside the motor bin through a mounting frame, a top cover cap is installed on the output shaft of the second servo motor, and the top cover cap is sleeved on the top of the outer side of the motor bin, and a first camera is installed on the top of the top cover cap.

[0013] Through the above technical solution, the second servo motor inside the motor compartment is controlled to drive the top cover cap to slowly rotate to a specified angle, and the first camera on the top of the top cover cap also rotates synchronously, thereby realizing free adjustment of the patrol angle of the first camera.

[0014] Furthermore, the supporting mechanism includes a mounting seat, which is provided with two groups, and the two groups of mounting seats are symmetrically installed at the middle positions of the two ends of the bottom bin, the mounting seat is hinged with a U-shaped frame at one end away from the bottom bin, auxiliary rollers are symmetrically installed on both sides of the U-shaped frame away from one end of the bottom bin, sliding rods are symmetrically installed at the middle positions of the two ends of the top of the mounting plate, and a lifting seat is sleeved on the outer side of the sliding rod, one end of the lifting seat is hinged with a connecting rod through a hinge, and the end of the connecting rod away from the lifting seat extends to the outside of the top bin and is hinged to the middle position of the top of the U-shaped frame.

[0015] Through the above technical solution, when the lifting seat on the outer side of the sliding rod descends, the lifting seat drives the U-shaped frame to rotate and unfold around the hinge shaft connected with the mounting seat by cooperating with the connecting rod until the two sets of auxiliary rollers on the U-shaped frame are against the ground. Then, when the entire mobile mechanism moves through the traveling wheels, the two pairs of auxiliary rollers also roll on the ground, thereby greatly improving the stability of the entire mobile mechanism during movement or turning.

[0016] Furthermore, the hinged part includes a groove located at one end of the lifting seat, the end of the connecting rod close to the lifting seat extends into the groove, and limiting circular holes are symmetrically opened on both sides of the inner side of the groove, and limiting columns adapted to the limiting circular holes are symmetrically installed on both sides of the connecting rod close to the lifting seat.

[0017] Through the above technical solution, during the lifting process of the lifting seat, the connecting rod can always be stably hinged with the lifting seat, so that the connecting rod can stably push the U-shaped frame to rotate and expand or collapse around the hinge axis connected to the mounting seat.

[0018] Furthermore, a triangular support block is installed at the bottom of the mounting seat, and strip-shaped through grooves that cooperate with the connecting rod are symmetrically opened at the middle positions of the two ends of the top bin.

[0019] Through the above technical solution, the triangular support block helps to improve the stability of the mounting base supporting the U-shaped frame, while the strip-shaped through groove allows the connecting rod to be free from the restriction of the top bin shell during movement.

[0020] Furthermore, the linkage mechanism includes an active rack, which is provided with two groups, and the two groups of active racks are symmetrically installed at the bottom end of the outer side of the internal threaded tube, vertical plates are symmetrically installed on both sides of the top of the mounting plate, and two groups of transmission gears meshing with the active racks are commonly provided on the top of the inner sides of the two groups of vertical plates, and strip plates are symmetrically installed at the ends of the two groups of lifting seats close to each other, and a driven rack meshing with the transmission gear is installed at the end of the strip plate away from the lifting seat.

[0021] Through the above technical solution, during the lifting process of the internal threaded tube, the active rack on the outside of the internal threaded tube drives the driven rack to rotate, and the driven rack drives the driven rack on the strip plate to move up and down, thereby driving the lifting seat fixedly connected to the strip plate to move up and down on the slide rod, and also realizing the two sets of U-shaped frames being rotated around the hinge shaft connected to the mounting seat as the axis to expand or collapse.

[0022] Furthermore, fixed bearings are symmetrically installed at both ends of the outer side of the transmission gear shaft, and the outer ring of the fixed bearing is fixedly connected to the inner side of an adjacent set of vertical plates.

[0023] Through the above technical solution, during the rotation of the transmission gear, the fixed bearing helps to improve the stability of the rotation of the transmission gear, thereby improving the stability of the internal threaded tube driving the two sets of U-shaped frames to expand or retract.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention is provided with an inspection mechanism that can freely adjust the horizontal inspection angle, thereby effectively improving the inspection equipment's ability to conduct detailed inspections on the cables on both sides of the mobile mechanism; (2) The present invention is provided with a lifting mechanism that can freely adjust the height of the inspection mechanism according to actual inspection needs, so that the inspection mechanism can inspect cables of different heights. In combination with the lifting mechanism that can adjust the height of the inspection mechanism, the use effect of the inspection equipment on the mobile mechanism can be further improved; (3) The present invention is provided with a supporting mechanism, and then the lifting mechanism is used in conjunction with the linkage mechanism to automatically control the folding or unfolding of the supporting mechanism. After the supporting mechanism is unfolded, it can provide stable support for the entire mobile mechanism, so that the mobile mechanism for visual cable inspection can remain stable during turning to avoid tipping over. After the supporting mechanism is folded, the occupied space of the entire mobile mechanism will not be increased, which is convenient for transportation and storage of the mobile mechanism.
