The first turn 6 not only realizes the connection between the locomotive and the aerial work device, but also the turning action of the first turn 6 can make the main arm assembly 5 and the second turn The second turn 4 deviates from the longitudinal symmetrical position of the locomotive, so as to avoid the catenary directly above the locomotive in space on the whole aerial work device.

The main arm assembly 5 is hinged between the first turntable 62 and the second turntable 42, including the main arm 51, the connecting rod 52, and the first luffing oil cylinder 53, one end of the first luffing oil cylinder 53 is hinged to the first turntable 62, and the other end Hinged to the main arm 51, the luffing cylinder changes the inclination angle of the main arm, increasing the flexibility of the mechanism and the working range. The connecting rod 52 is hinged between the first turntable 62 and the fixed body 422. By forming a four-bar linkage mechanism with the main arm 51, the first turntable 62 and the fixed body 422, the mechanical leveling of the second rotary 4 is realized by using the parallelogram principle.

The second rotary 4 comprises a second rotary mechanism 41 and a second turntable 42. The second rotary platform 42 includes a rotary body 421 and a fixed body 422. The rotary body 421 and the fixed body 422 are connected to the second rotary mechanism 41 by bolts. Under the action of the rotary mechanism 41 , the rotary body 421 and the fixed body 422 can rotate relative to each other. During the obstacle avoidance process, the second turning 4 makes the boom assembly 5, the working platform 1 and the connecting components between them deviate from the longitudinal symmetrical position of the locomotive. After getting out of the way, the second turning 4 makes the boom assembly 5, the operating platform 1 and the connection assembly between the two get back to the locomotive directly above.

The boom assembly 3 includes a basic arm 31, a first-stage telescopic arm 32, a second-stage telescopic arm 33, a third-stage telescopic arm 34, a telescopic oil cylinder 35, and a second luffing oil cylinder 36; one end of the second luffing oil cylinder 36 is hinged to the basic arm 31. The other end is hinged to the revolving body 421.

The third rotary 2 includes a third turntable 21 and a swing cylinder 22 , and the swing cylinder 22 is hinged between the working platform 1 and the third turntable 21 . The swing cylinder 22, the third turntable 21, and the work platform 1 form a link mechanism.

working principle:

During work, the leveling system 7 detects the inclination angle of the operation platform 1, and keeps the operation platform 1 leveled all the time. Under the action of the second luffing cylinder 36 , the boom assembly 3 swings in a small range, so that the bottom of the working platform 1 is separated from the working platform bracket 81 .

The main arm assembly 5 realizes amplitude luffing under the action of the first luffing cylinder 53 , and the main arm assembly 5 leaves the arm body bracket 82 . The parallelogram link mechanism formed by the connecting rod 52 , the main arm 51 , the first turntable 62 and the fixed body 422 mechanically balances the second turn 4 in real time. The first turn 6 turns to a certain side of the locomotive, so that the second turn 4 avoids the catenary in the vertical direction.

The second turn 4 turns to make the boom assembly 3, the operating platform 1 and the connecting components between them deviate or return to the top of the locomotive, so that the boom assembly 3, the working platform 1 and the connecting components between them are in the vertical direction Non-interference with catenary. The amplitude of the boom assembly 3 is changed, and the operating platform 1 is raised vertically above the catenary.

According to the needs of the operation, adjust the rotation angle of the second rotation 4, the luffing angle of the main boom assembly 5 and the boom assembly 3, and the telescopic length of each arm of the boom assembly 3, so that the working platform 1 reaches the designated area, and the third rotation 2 rotations to realize fine-tuning of the position of the working platform 1 and improve the accuracy of the working position.

The above-mentioned process can realize the coverage of the work scope on the fan-like space within the tunnel limit on one side of the locomotive. Similarly, after the working platform 1 and the main arm assembly 5 leave the bracket 8, the first turning 6 turns in the opposite direction. Repeating the above operations, the device can fully cover the sector-like space within the tunnel boundary on the other side of the locomotive;

To sum up, the utility model successfully achieves the purpose of full-section working coverage of the track tunnel through the functional combination of three-stage slewing, two-stage luffing, and three-stage telescopic arm body.

Through the combination of the first and second rotations and the luffing action of the main arm, the working platform can return to the top of the locomotive after effectively bypassing obstacles. The telescopic arm's luffing and telescopic functions enable the working range of the working platform to cover the fan-shaped space on one side of the locomotive in the tunnel. After the device is retracted, the first rotation is reversed, and the working range can cover the fan-shaped space on the other side of the locomotive in the tunnel. The above process realizes that the working range covers all the spaces in the same section of the track tunnel, which greatly reduces the working time occupied by shunting and improves working efficiency.
