A contraction groove 24 is provided on the lower surface of the base 1, the outer surface of the rotating shaft 5 is rotatably connected to the fixing plate 3, the first conical tooth 6 is meshed with the second conical tooth 8, and the driving motor 4 is electrically connected to an external power supply.
[0026] The upper surface of the base 1 is fixedly connected to a handle 12, the upper surface of the base 1 is fixedly connected to a connecting chamber 13, the outer surface of the connecting chamber 13 is fixedly connected to a double-headed motor 14, the output end of the double-headed motor 14 is fixedly connected to a lead screw 15, the end of the lead screw 15 away from the double-headed motor 14 is fixedly connected to a limit block 16, the outer surface of the lead screw 15 is threadedly connected to an L-shaped slider 18, the outer surface of the L-shaped slider 18 is fixedly connected to a toothed plate 19, the inner surface of the connecting chamber 13 is rotatably connected to a rotating column 20, and the outer surface of the rotating column 20 is fixedly connected to a gear The seat 21 and the lower surface of the gear seat 21 are fixedly connected with a roller 22. The outer surface of the connecting bin 13 is provided with a limiting groove 23. The inner surface of the limiting groove 23 is adapted to the L-shaped slider 18. The inner surface of the contraction groove 24 is adapted to the roller 22. The outer surface of the lead screw 15 is provided with a thread 17. The tooth plate 19 is engaged with the gear seat 21. There are four rollers 22 and they are distributed in a rectangular array. There are two connecting bins 13 and they are distributed front and back. The outer surface of the adjusting seat 2 is in contact with the connecting bin 13. The double-headed motor 14 is electrically connected to the external power supply.
[0027] Working principle: When working, under the action of the roller 22, the handle can be used to conveniently push the entire device to move to the rear of the manhole cover. After arriving, the double-headed motor 14 is started, and the lead screw 15 drives the tooth plate 19 to move along the limit groove 23 under the action of the L-shaped slider 18. At this time, the gear plate 19 and the gear seat 21 can be meshed to drive the gear seat 21 and the roller 22 to flip at a certain angle as a whole, so that the roller 22 is separated from the ground and retracted into the cavity formed by the connecting chamber 13 and the base 1 through the retraction groove 24, so that the base 1 contacts the ground to ensure that the roller 22 will not be damaged by the contact between the roller 22 and the ground. The surface contact area is too small, resulting in the device shifting, thereby reducing the risk of the manhole cover falling off when opening and closing. Then, the buckle block 11 is inserted into the pry hole above the manhole cover, and the drive motor 4 is started to drive the rotating shaft 5 to drive the rotating shaft 5, the second conical tooth 8, the connecting shaft 7, and the storage wheel 9 to rotate, thereby reeling the opening rope 10, so that the manhole cover is flipped around the flip axis to open the manhole cover. When closing the manhole cover, it is only necessary to start the drive motor 4 in reverse. Under the action of the gravity of the manhole cover itself, the manhole cover will complete the closing operation. The entire process does not require manual opening and closing of the manhole cover, and the efficiency is high.
[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
