Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figures 1 to 5 The utility model provides an embodiment: a drill pipe detection device includes a horizontally arranged truss 1, a center plate 2 fixedly arranged on the truss 1 through a leveling mechanism, and a detection motor 4 fixedly arranged on the center plate 2 through a connecting plate 3; the leveling mechanism is four inclined irons, and the inclined irons are an upper inclined iron 81 and a lower inclined iron 82 that are buckled together, and the upper inclined iron 81 and the lower inclined iron 82 are connected by adjusting bolts 85, the upper inclined iron 81 is connected to the center plate 2, and the lower inclined iron 82 is connected to the truss 1, and the center plate 2 and the truss 1 are also fixedly connected by multiple bolts 9; the center plate 2 is also provided with an adapter 6 through a tapered bearing 5, the upper end of the adapter 6 is connected to the output shaft of the detection motor 4, and the lower end of the adapter 6 is connected to the drill pipe 7.

[0026] Specifically, the detection motor 4 is fixed to the center plate 2 through the connection plate 3, the center of the center plate 2 is fixedly connected to the adapter 6 through the tapered bearing 5, one end of the adapter 6 is connected to the detection motor 4, and the other end is connected to the drill pipe 7 to be detected. The detection motor 4 drives the adapter 6 to rotate, and the drill pipe 7 will also rotate accordingly.

[0027] The inclined surface of the lower inclined iron 82 is provided with a guide groove 84, and the inclined surface of the upper inclined iron 81 is provided with a guide rail 83 adapted to the guide groove (84). The four inclined irons are divided into two groups, and the inclined surfaces of the lower inclined irons 82 of the same group of inclined irons correspond to each other, and the horizontal projections of the four guide rails 83 are parallel.

[0028] Specifically, before the detection, four inclined irons are first used to vertically adjust the axis of the output shaft of the detection motor 4. The axis of the output shaft of the detection motor 4 is adjusted to coincide with the axis of the adapter. When the inclined iron is adjusted, the axis of the adapter 6 will also be vertical to facilitate subsequent work.

[0029] A set of inclined irons is composed of upper and lower inclined irons. By adjusting the bolt 85, the adjusting bolt 85 is screwed in and out, and the screwed-in bolt is tightened, so that the upper inclined iron 81 and the lower inclined iron 82 are squeezed, and then both move along the inclined surface, thereby adjusting the horizontality of the center plate 2, thereby adjusting the adapter 6 and detecting the axis of the motor 4.

[0030] The upper inclined iron 81 is connected to the center plate 2, and the lower inclined iron 82 is connected to the truss 1. The center plate 2 and the truss 1 are also fixedly connected by a plurality of bolts. After the adjustment bolts 85 of the plurality of inclined irons level the entire center plate 2, that is, after the vertical axis of the adapter 6 is leveled, the plurality of bolts between the center plate 2 and the truss 1 are tightened to fix the adjusted center plate 2 and the truss 1.

[0031] The guide rails 83 and guide grooves 84 matched with the upper inclined iron 81 and the lower inclined iron 82 can constrain the positions of the center plate 2 and the truss 1 fixedly connected thereto.

[0032] The device also includes a standard measuring point. The standard measuring point is a marking line, a marking plate, or a ruler. The marking line can be a laser line or a steel line.

[0033] Specifically, at the lowermost tail end of the suspended drill pipe, the straightness of the drill pipe 7 can be directly reflected by swinging the tail of the drill pipe 7 through laser marking, wire drawing, grid backboard, and light projection.

[0035] The working principle of the spirit level is as follows: when the drill pipe needs to be inspected, the whole mechanism is first adjusted to be level through the leveling mechanism. The multiple bolts 9 fixing the center plate 2 and the truss 1 are tightened to fix the adjusted center plate 2. The adapter 6 of the drill pipe 7 can be kept vertical when it is hung. After the drill pipe 7 is hung, the spirit level is placed so that the light emitted by the spirit level is tangent to the edge of the drill pipe, and the inspection motor 4 is started to observe the offset between the drill pipe 7 and the spirit level light and the swing amplitude of the tail of the drill pipe 7, so as to determine the qualification of the drill pipe.
