For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0024] The present application embodiment provides an adjustable taphole opening machine, such as Figures 1 to 5 As shown. The adjustable iron mouth opening machine includes a rail beam 1, a rotating mechanism 2, a fixing mechanism 3, an adjusting bolt 5, a hanging member 4, a control connecting rod 6 and a base 7. The base 7 is connected to the foundation. One end of the rotating mechanism 2 is hinged to the base 7, and the other end thereof is connected to the fixing mechanism 3 through the hanging member 4, and the fixing mechanism 3 is configured to press the side of the rotating mechanism 2 away from the base 7. The hanging member 4 is suspended from the rotating mechanism 2, and the bottom of the hanging member 4 is connected to the rail beam 1. One end of the control connecting rod 6 is hinged to the rotating mechanism 2 and is close to the hanging member 4, and the other end thereof is hinged to the base 7, and an upper pipeline 8 is arranged above the control connecting rod 6. The adjusting bolt 5 is connected to the nut of the hanging member 4 through the fixing mechanism 3. When the drill bit of the adjustable iron mouth opening machine is aligned with the iron mouth, the adjusting bolt 5 is configured to drive the hanging member 4 to move so that the center line of the rail beam coincides with the center line of the iron groove.

[0025] The end of the hanging member 4 in the embodiment of the present application away from the rotating mechanism 2 is connected to the rail beam 1 by bolts.

[0026] It should be noted that in actual operation, the rotating mechanism 2 drives the hanging member 4 and the rail beam 1 to rotate, and moves the rail beam 1 from the standby position to the working position. When deviation occurs in the iron mouth or foundation construction, the length of the control connecting rod 6 is adjusted so that the center line of the rail beam is parallel to the center line of the iron groove; the fixing mechanism 3 is loosened so that the adjusting bolt 5 drives the hanging member 4 to move so that the center line of the rail beam coincides with the center line of the iron groove. Therefore, the adjustable iron mouth opening machine of the embodiment of the present application can make the center line of the rail beam coincide with the center line of the iron groove, avoid deviation when the iron mouth opening machine drills the iron mouth, and has a reasonable structure and convenient operation.

[0027] Furthermore, the two ends of the swing arm 21 of the prior art are hinged to the swing arm frame and the angle adjustment frame, the swing arm frame is installed on the column, and the two ends of the rotary cylinder 24 are respectively hinged to the swing arm 21 and the swing arm frame, and drive the swing arm 21 to rotate around the front end of the swing arm frame. Therefore, the rotation center of the prior art is a certain distance from the center of the column, and the weight of the whole machine is heavy, so that the foundation is subjected to a large overturning load. The rotating mechanism 2 of the embodiment of the present application is hinged to the base 7, so that the rotation center and the center of the base 7 coincide, and the weight of the whole machine is light, so that the foundation is subjected to a small overturning load.

The adjusting frame 22 is connected to the fixing mechanism 3 through the hanging member 4. The hanging member 4 is suspended on the adjusting frame 22, and the fixing mechanism 3 is configured to be pressed against the bottom of the hanging member 4 and the side of the adjusting frame 22 away from the central column 23 to prevent the adjusting frame 22 from moving. The central column 23 is fixedly connected to the end of the adjusting frame 22 away from the fixing mechanism 3, and forms an L-shaped structure with the adjusting frame 22. The two ends of the rotating arm 21 are respectively hinged to the side of the central column 23 away from the adjusting frame 22 and the base 7.

The end of the control link 6 away from the base 7 is hinged to the central column 23.

[0029] The rotary cylinder 24 of the embodiment of the present application drives the rotating arm 21 to rotate, so that the rotating arm 21 drives the central column 23, the adjustment frame 22, the hanging member 4 and the rail beam 1 to rotate. Therefore, the rotary cylinder 24 of the embodiment of the present application can drive the adjustable iron mouth opening machine from the standby position to the working position.

[0030] In the embodiment of the present application, the rotating mechanism 2 further includes a pressure cover 25. The end of the rotating arm 21 away from the base 7 is connected to the side wall of the central column 23 through a bearing 27. The pressure cover 25 is sleeved on the central column 23 and is located at the bottom of the bearing 27. The pressure cover 25 is pressed against the bearing 27 through a first fastener 26. The pressure cover 25 in the embodiment of the present application is used to press the bearing 27, so that the overall structure is more stable.

[0031] In the embodiment of the present application, the rotating mechanism 2 further comprises a connecting plate 28 .

The fastening cover plate 29 is disposed on a side of the connecting plate 28 away from the central column 23, and the connecting plate 28 is connected to the central column 23 via the fastening cover plate 29 and the second fastener. The fastening cover plate 29 of the embodiment of the present application makes the overall structure more stable.

[0035] In the embodiment of the present application, the fixing mechanism 3 includes a fixing plate 31 and a pressing plate 32. The fixing plate 31 is fixedly connected to an end of the adjustment frame 22 away from the center column 23. The adjusting bolt 5 passes through the fixing plate 31 and is connected to the nut of the hanging member 4. The pressing plate 32 is arranged at the bottom of the adjustment frame 22 and is configured to be connected to the hanging member 4 through a third fastener.

[0036] It should be noted that if Figure 3A , 3B As shown in 3C, when the adjustable iron mouth opening machine is in the working position, adjust the length of the control connecting rod 6 so that the center line of the rail beam 1 is parallel to the center line of the iron groove, then loosen the third fastener, loosen the pressure plate 32, and rotate the adjusting bolt 5 so that the adjusting bolt 5 drives the hanging part 4 to move left and right on the adjusting frame 22, so that the center line of the rail beam 1 can coincide with the center line of the iron groove.
