The specific implementation mode is as follows:
the technical solution of the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the anti-swing arm rotating mechanism for top drive rotating casing running equipment comprises: a rectangular plate-shaped base 1 and a tubular anti-rotation arm 2; a U-shaped notch 11 is formed in the middle of one edge of the rectangular surface of the base 1, strip-shaped long circular holes 12 are formed in two sides of the U-shaped notch 11, and the long edges of the two long circular holes 12 are parallel to the central line of an opening of the U-shaped notch 11; and a socket device for inserting and fixing the anti-rotation arm is arranged on one side of the rectangular surface of the base 1, which is opposite to the opening direction of the U-shaped notch 11.
The socket device consists of two identical square tubes A3 vertically fixedly connected to the base 1 (in the embodiment, two square tubes A3 are welded on the base 1), and at least one side of the rectangular cross section of each square tube A3 is parallel to at least one side of the rectangular surface of the base 1; the positions of the two square tubes A3 on the rectangular surface of the base 1 are symmetrical about the center line of the opening of the U-shaped notch 11; the side wall of each square tube A3 is provided with a screw hole A31.
As shown in fig. 2, the anti-rotation arm 2 is composed of two parallel vertical tubes 21 with equal length. Viewed from the anti-rotation arm 2 as a whole, the present embodiment has the faces that can see two risers 21 simultaneously as the front or back of the anti-rotation arm 2, and correspondingly, the faces that can see only one riser 21 are both side faces of the anti-rotation arm 2. A pair of adjacent ends of the bottoms of two parallel and equal-length vertical pipes 21 are fixedly connected through a fixing plate 22 (in the embodiment, the fixing plate 22 is welded on the end surfaces of the two ends at the same time), a pair of adjacent ends of the tops are coaxially connected (in the embodiment, in a welding manner) with square pipes B23, and the side wall of each square pipe B23 is provided with a screw hole B231; the distance between the two square tubes B23 is the same as the distance between the two square tubes A3 on the base 1, and the shape and the size of the square tube B23 are matched with those of the square tube A3, so that the square tube B23 can be completely inserted into the square tube A3; meanwhile, the position of the screw hole B231 on the square tube B23 meets the following requirements: in a state where the square tube B23 is inserted into the square tube A3, the screw hole a31 and the screw hole B231 can be overlapped. In the use state (shown in fig. 6), the square tube B23 is inserted into the square tube A3, and the screw hole a31 and the screw hole B231 are overlapped and fastened by a bolt, thereby completing the fastening of the base 1 and the rotation-preventing arm 2.
The two square tubes a3 are connected by a pair of parallel rectangular reinforcing plates 4, and each reinforcing plate 4 is vertically fixed (welded) on the base 1 (shown in fig. 1). The reinforcing plate 4 can further improve the stability of the welding structure of the base 1 and the square tube A3, and effectively prevent the deformation of the square tube A3 and the damage and fracture of the connecting part of the square tube A3 and the base 1 in the operation process.
And a rectangular reinforcing plate 5 is connected between the lower pipe sections of the two vertical pipes 21, and the rectangular plate surface of the reinforcing plate 5 is parallel to or coincided with the plane where the two vertical pipes 21 are located. The gusset plate 5 fixedly connected between the two vertical pipes 21 can further improve the rigidity and stability of the parallel vertical pipe structure of the anti-rotation arm 2, and the anti-rotation arm 2 is guaranteed not to deform under the action of external force.
The reinforcing plate 5 is connected with the vertical pipes 21 on two sides thereof in a bolt fixing mode, and the concrete structural design is as follows: the body of the vertical pipe 21 is a pipe with a rectangular cross section; screw holes C211 are formed in the pipe surfaces of the two vertical pipes 21 on the same plane (namely, the front surface or the back surface of the anti-rotation arm 2), the lower pipe section is provided with screw holes D51 (shown in FIG. 4) at the same horizontal height, the connecting area between the rectangular surface of the reinforcing plate 5 and the two vertical pipes is respectively provided with a screw hole D3578, and the distance between the two screw holes D51 on the reinforcing plate 5 is the same as the distance between the screw holes C211 on the two vertical pipes 21. In the use state, the reinforcing plate 5 is located on the tube surface of the vertical tube 21 on the front surface (or the back surface) of the rotation preventing arm 2, and the screw hole C211 and the screw hole D51 on each side are overlapped and fastened by a bolt on the connecting portion of the reinforcing plate 5 and the vertical tube 21 on both sides thereof.
In order to make the height position of the reinforcing plate 5 on the two vertical pipes 21 adjustable within a certain range in the use state, the present embodiment adopts the following more preferable structural design: a plurality of pairs of screw holes C211 are arranged on the pipe surfaces of the two vertical pipes 21 on the same plane along the length direction of the pipes in the lower pipe section; for each pair of screw holes C211, the screw hole positions on the two vertical pipes are at the same horizontal level (shown in fig. 3). The dimensions of the reinforcing plate 5 furthermore satisfy: when the reinforcing plate 5 is connected to the two vertical tubes 21, both ends of the reinforcing plate 5 connected to the vertical tubes 21 slightly protrude from both sides of the rotation preventing arm 2 formed by the two vertical tubes 21 (shown in fig. 5). In the use state, when the reinforcing plate 5 is positioned between two parallel swing arms of the lower casing equipment, the protruding parts of the reinforcing plate 5 on the two sides of the rotation-preventing arm 2 can further increase the blocking effect of the rotation-preventing arm 2 on the rotation of the swing arms (shown in fig. 6 and 7).
When the base is used on site, the base 1 is fixed at the lower part of the top drive, the base 1 is installed at the lower part of the top drive in a bolt fastening mode through two long round holes 12 on the base 1 and screw holes corresponding to the lower part of the top drive, and meanwhile, a casing string 6 at the lower part of the top drive is clamped into a U-shaped notch 11 of the base 1. The base 1 is usually installed at the position of a top drive grouting bell mouth, and the base 1 can be installed by matching a fixing screw hole of the bell mouth with a long circular hole 12 on the base 1 after the bell mouth is removed. Compared with the common screw hole, the long round hole 12 on the base 1 can provide more fixing positions and can be matched with the screw holes at different positions on the top drive for fixing and mounting.
After the base 1 is installed, the anti-rotation arm 2 penetrates through the parallel lower casing equipment swing arms 7, so that the anti-rotation arm 2 is positioned between the two lower casing equipment swing arms 7; the anti-rotation arm 2 is fixedly connected with the base 1 above the anti-rotation arm, and then the height position of the reinforcing plate 5 is adjusted to be just between two lower casing equipment swing arms 7 (shown in figures 6 and 7). After the installation is completed, the top drive rotating lower casing equipment swing arm rotating mechanism is adopted, and two vertical pipes 21 of the rotating preventing arm 2 and the reinforcing plate 5 are completely wedged between the two lower casing equipment swing arms 7, so that the rotation of the lower casing equipment swing arms 7 is effectively prevented. When the swing arm direction needs to be adjusted, the top drive direction only needs to be adjusted.
The above embodiments are only for illustrating the present invention, and all equivalent changes and modifications made on the basis of the technical solutions of the present invention should not be excluded from the scope of the present invention.
