[0015] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The following will further describe the technical solutions of the present utility model with reference to the drawings of the embodiments of the present utility model. The present utility model is not limited to the following specific embodiments.

[0016] It should be understood that the same or similar reference numerals in the accompanying drawings of the embodiments correspond to the same or similar components. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the accompanying drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0017] The present utility model relates to a rapid leveling and scribing device for an excavator in dam panel concrete pouring, as Figure 1 — Figure 4 shown, which includes an excavator body 1. The excavator body 1 is connected to a boom 15, and the boom 15 is connected to a dipper arm 16. Oil cylinders 17 are respectively arranged on the boom 15 and the dipper arm 16. A connecting frame 2 is arranged on the dipper arm 16. A screed board 3 is arranged on the bottom surface of the connecting frame 2. A connecting plate 4 is arranged in the connecting frame 2. Scribing boards 5 are evenly arranged on the bottom surface of the connecting plate 4. Fixing plates 6 are respectively arranged on the left and right sides of the top surface of the connecting plate 4. A slot 7 is opened on one side of the fixing plate 6. Threaded holes 18 are respectively opened on both sides of the connecting frame 2. Screws 8 are arranged in the threaded holes 18. The screws 8 are in threaded cooperation with the threaded holes 18. One end of the screw 8 close to the fixing plate 6 is connected to a connecting block 9 by a bearing. An insertion block 10 is arranged on one side of the connecting block 9 close to the fixing plate 6. The insertion block 10 is in plug-in fit with the slot 7. A hexagonal nut 11 is fixedly connected to the side of the screw 8 away from the fixing plate 6.

[0018] Furthermore, a positioning groove 12 is opened in the middle of the connecting frame 2, and the bottom of the connecting plate 4 is inserted into the positioning groove 12. With the positioning groove 12, it can play a positioning role for the connecting plate 4 and the scribing board 5, and avoid the situation that one side is much heavier than the other side after the connecting plate 4 is installed in the connecting frame 2.

[0019] Furthermore, a movable hole 19 is opened in the connecting block 9, and a guide rod 13 is movably sleeved in the movable hole 19. One end of the guide rod 13 is fixedly connected to the inner wall of the connecting frame 2. With the movable hole 19 and the guide rod 13, the connecting block 9 can be restricted to prevent the connecting block 9 from rotating along with the screw 8.

[0020] Furthermore, a connecting seat 14 is fixedly connected to the middle of the top surface of the connecting plate 4. Two connecting grooves 20 are formed in the top of the connecting seat 14. The small arm 16 of the excavator body 1 and the oil cylinder 17 on the small arm are respectively hinged in the connecting grooves 20. With the connecting seat 14 and the connecting grooves 20, it is convenient to install the connecting plate 4 on the small arm 16 of the excavator body 1 and the oil cylinder 17 of the small arm 16.

[0021] The utility model discloses a rapid leveling and grooving device for an excavator in dam panel concrete pouring. When in use, first, the connecting seat 14 can be hinged on the small arm 16 of the excavator body 1 and the oil cylinder 17 of the small arm 16 in the same way as installing a bucket through the two connecting grooves 20 on the connecting plate 4. Then, by operating the boom 15 and the small arm 16 on the excavator body 1, the bottom surface of the screed board 3 is made to fit the concrete on the dam body. Then, the excavator body 1 operates the screed board 3 to move on the concrete, and the concrete on the dam body can be leveled. After the concrete on the dam body is leveled, use a wrench to turn the hexagonal nut 11 to drive the screw rod 8 to rotate. The screw rod 8 moves outward from the connecting frame 2. The screw rod 8 drives the connecting block 9 to move, and the connecting block 9 drives the inserting block 10 to move, so that the inserting block 10 is pulled out from the slot 7 on the fixing plate 6, thereby releasing the fixation between the connecting frame 2 and the connecting plate 4, and detaching the connecting frame 2 from the connecting plate 4. At this time, the excavator body 1 moves the connecting plate 4 above the concrete on the dam body again, and makes the grooving board 5 at the bottom of the connecting plate 4 cooperate with the concrete, so that the lower end of the grooving board 5 is inserted into the concrete. Then, operate the excavator body 1 to make the connecting plate 4 move on the dam body, and the grooving board 5 follows to move, and anti-slip lines can be engraved on the concrete. In this way, after the excavator body 1 controls the screed board 3 to level the concrete on the dam body, the screed board 3 is disassembled, and the excavator body 1 operates the grooving board 5 to move on the concrete in the same way to engrave anti-slip lines. For a rapid leveling and grooving device for an excavator in dam panel concrete pouring in this solution, through the mutual cooperation between various components, after the excavator body 1 controls the screed board 3 to level the concrete on the dam body, the screed board 3 is disassembled, and the excavator body 1 operates the grooving board 5 to move on the concrete in the same way to engrave anti-slip lines. The installation and disassembly of the screed board 3 are very convenient, the operation is simple, there is no need to use other machines or manual labor to engrave anti-slip lines subsequently, the construction efficiency is improved, the labor intensity of workers is reduced, and the practicability of the device is enhanced.

[0022] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0023] The above embodiments only illustrate several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
