[0035] The implementation principle of this embodiment is:
[0036] First, a kit compatible with the monorail is installed on the outer side of the gear cylinder 16 for moving on the monorail surface. Then, the groove wheel 26 uses the transmission belt to rotate the speed gear 25. The speed change gear 25 is used in conjunction with the vertical gear 24 and the insertion gear 17 to drive the gear cylinder 16 to rotate. The speed change gear 25 is provided with gears of different radii. When the vertical gear 24 is in contact and meshing with the maximum radius gear of the speed change gear 25, the second hydraulic rod 23 is in a fully retracted state, and the first hydraulic rod 19 is in a fully extended state, so that the distance between the first vertical gear 24 and the speed change gear 25 is minimized, but they do not contact each other, and the transmission is transmitted through the insertion gear 17. The speed at this time is the highest. When the speed needs to be reduced, the multi-stage cylinder 14 starts to work, and the rack 13 is used in conjunction with the tooth groove 11 to drive the propulsion cylinder 9 to rotate forward by one quarter, and the positioning block 8 is pushed through the step of the propulsion cylinder 9 to move the installation cylinder 5 outward, and the installation cylinder 5 drives the gear mechanism to move. At the same time, the reset spring 7 is extended, and the first hydraulic rod 19 retracts a part of the cable to drive the insertion gear 17. Move to the bottom of the gear barrel 16, the second hydraulic rod 23 begins to extend, pushing the vertical gear 24 to mesh with gears of different radii of the speed gear 25 to complete the speed change. A total of four different gear ratios can be adjusted. By adjusting the speed with different gear ratios, the situation of long-term high-pressure load of the power equipment is effectively avoided, and the connecting shaft is effectively protected. When the speed of the gear barrel 16 needs to be increased, the first hydraulic rod 19 begins to extend, driving the inserted gear 17 to move the top of the slide slot 20, and the second hydraulic rod 23 contracts to drive the vertical gear 24 to move upward. Subsequently, the multi-stage cylinder 14 contracts, and the rack 13 is used to drive the propulsion barrel 9 to rotate in the opposite direction by one quarter, so that the positioning block 8 moves to the lower step. At the same time, the tension of the reset spring 7 to restore the deformation pulls the installation barrel 5 and the gear ratio mechanism 15 to move to the speed gear 25 with a larger radius, completing the increase of the speed of the gear barrel 16, adding different gear ratios, and reducing the situation of failure during use. Even if a single speed gear 25 is broken, the speed gear 25 of other radius can be replaced to continue moving, which is more convenient for maintenance at the end.
[0037] Compared with the prior art, the present invention has the following beneficial effects:
[0038] The multi-stage cylinder 14, the rack 13 and the tooth groove 11 are used in coordination to drive the propulsion cylinder 9 to rotate. The limiting groove 10 and the limiting frame 12 are used in coordination to limit the propulsion cylinder 9. The propulsion cylinder 9 and the positioning block 8 are used in coordination to push the gear ratio mechanism 15 to move. The addition of the return spring 7 can pull the installation cylinder 5. The addition of the positioning shaft 4 can prevent the installation cylinder 5 from rotating. The propulsion cylinder 9 pushes the gear ratio mechanism 15, so that the gear can adjust the moving speed through different ratios, which effectively reduces the power consumption of the power equipment and avoids the power equipment being in a high-voltage operation state for a long time. The gear cylinder 16 is added to connect the monorail. The slider 18, the slide groove 20 and the first hydraulic rod 19 are used in conjunction with each other to drive the inserted gear 17 to slide. The second hydraulic rod 23 and the mounting frame 22 are used in conjunction with each other to drive the vertical gear 24 to move up and down. The inserted gear 17 and the vertical gear 24 are used in conjunction with each other to transmit power. The first hydraulic rod 19 and the second hydraulic rod 23 are used in conjunction with each other to adapt the speed gear 25. When a gear of the speed gear 25 is damaged, other gears can be replaced to continue moving, complete the stroke, and then repair can be carried out, thereby avoiding the problem of power loss.
[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model.
