The upper cover 2 is provided with an arc opening, the top end of the upper cover 2 is fixedly provided with an arc-shaped drill rod adapter 3, and the radian of the drill rod adapter 3 is matched with the radian of the arc opening and the inner walls of the arc opening are flush. The radian of the drill rod adapter 3 and the radian of the arc-shaped opening of the upper cover 2 are larger than the radian of a semicircle. Thereby, the drill 12 is prevented from being separated in the horizontal direction, and the stability of supporting the drill rod 12 is ensured. The drill rod adapter 3 has a holder 31 which mates with the shrink connection of the drill rod 12. The bolt assembly comprises two bolts 4 and two arc-shaped pull rods 5. The two lock bolts 4 are respectively connected with the inner walls of the two arc-shaped clamp arms in a circumferential sliding manner, the two lock bolts 4 are respectively connected with the two arc-shaped pull rods 5 in a rotatable manner, the two arc-shaped pull rods 5 are connected with a telescopic mechanism, and the telescopic mechanism can drive the arc-shaped pull rods 5 to drive the two lock bolts 4 to slide along the circumferential directions of the two arc-shaped clamp arms, so that the clamping opening is closed or opened. In this embodiment, the two bolts 4 are connected with the two arc-shaped pull rods 5 through pin shafts. The two arc-shaped pull rods 5 are also connected with the telescopic mechanism through pin shafts. The installation end of the telescopic mechanism extends out of the side part of the clamp body 1 and is connected to the outer side of the clamp body 1 through a connecting pin, so that the telescopic mechanism is convenient to disassemble and maintain. The cross sections (transverse cross sections perpendicular to the vertical direction) of the two lock bolts 4 are arc-shaped. The two lock tongues 4 enclose a clamping opening and then form a circular clamping cavity with the two arc-shaped clamp arms, and the cross section size of the circular clamping cavity is designed to be larger than the cross section size of the drill rod 12 positioned in the circular clamping cavity. Thus, the two locking tongues 4 do not affect the bearing effect of the drill rod 12, but merely form a rounded space for righting the drill rod 12.
Specifically, according to the drill rod bearing assembly for the derrick racking platform provided by the embodiment, according to the structural characteristics of the drill rod 12, a bearing frame of the drill rod 12 is formed through the clamp body 1 and the upper cover 2 fixed at the top end of the clamp body, the drill rod 12 is righted through the telescopic connection part of the drill rod adapter 3, and the spring bolt assembly is driven by the telescopic mechanism to prevent the drill rod 12 from inclining in the process of grabbing or discharging the drill rod 12. Compared with the prior art, the drill rod bearing assembly only abuts against the shrinkage connecting part of the drill rod 12 through the bearing part 31 of the drill rod adapter 3, damage to the surface of the drill rod 12 is avoided, and sliding of the drill rod 12 can be avoided in the process of bearing the drill rod 12, so that the safety is higher. And the shape of the bearing part 31 is matched with the shrinkage connecting part, the shrinkage connecting part can uniformly transfer the gravity of the drill rod 12 to the bearing part 31, and the bearing capacity of the drill rod bearing assembly can be further improved.
Specifically, in this embodiment, the shape of the support 31 is an arcuate recess having an inner wall shape and size that matches the shape and size of the converging connection portion of the drill pipe 12 and is tapered. Under the view angle of the vertical section, the tangent value of the included angle between the straight line where the inner wall of the arc-shaped notch and the shrinkage connecting part of the drill rod 12 are located and the vertical straight line is smaller than the static friction factor between the inner wall of the arc-shaped notch and the shrinkage connecting part. Thus, after the bearing 31 abuts against the contractive connection portion of the drilling tool 12, the bearing and the drilling tool can be friction-locked (meaning that if the line of action of the combined force acting on the main force of the object is within the friction angle, no matter how large the force is, there is always a full counter force balanced with the force, and the object remains stationary), so as to improve the stability of the bearing and the drilling tool.
Further, as shown in fig. 1, 2 and 4, the drill rod support assembly for a derrick racking platform provided in this embodiment further includes an arc-shaped spacer 7. Two arc grooves which are positioned on the same arc line along the circumference of the inner wall of the two arc clamp arms of the clamp body 1 are formed, and the arc gasket 7 fills the arc grooves of the two arc clamp arms.

The two lock bolts 4 are guided by the arc-shaped gaskets 7 and the arc-shaped sliding grooves, so that dislocation of the lock bolts 4 in the process of closing or opening the clamping opening is avoided.
Further, as shown in fig. 1, 3 and 4, a positioning pin assembly 6 is also fixed on the top of the upper cover 2. The drill rod adapter 3 has mounting grooves at both ends, which abut against two mounting protrusions on top of the upper cover 2. The drill rod adapter 3 is held against its middle by a dowel assembly 6 to be fixed on top of the upper cover 2. An abutting groove is formed in the middle of the top end of the drill rod adapter 3, and the shape of the abutting groove is matched with that of a pin shaft of the locating pin assembly 6. The mounting position of the drill rod adapter 3 is precisely controlled by means of the dowel assembly 6.
Preferably, as shown in fig. 4, in this embodiment, the telescopic mechanism is a telescopic hydraulic cylinder 8, and a telescopic rod of the telescopic hydraulic cylinder 8 is rotatably connected with two arc-shaped pull rods 5 through a connecting block 9. The two arc-shaped pull rods 5 are conveniently connected through the connecting block 9. The inside of the pliers body 1 is provided with a guide rail 10 with the same movement direction as the connecting block 9, and the connecting block 9 is connected on the guide rail 10 in a sliding way through a sliding groove formed in the bottom of the connecting block 9. Through the guide rail 10 and the connecting block 9 of the internal fixation of the clamp body 1, on the one hand, the telescopic motion of the telescopic rod of the telescopic hydraulic cylinder 8 can not be imaged, and on the other hand, the telescopic hydraulic cylinder 8 is provided with supporting connection, so that the telescopic hydraulic cylinder 8 is arranged in the clamp body 1.

In the process that two spring bolts 4 seal the clamping opening, the connecting block 9 is driven to slide along the guide rail 10 through the telescopic rod of the telescopic hydraulic cylinder 8, the connecting block 9 drives the two arc pull rods 5 to move, when the two arc pull rods 5 drive the two spring bolts 4 to slide along the arc gaskets 7 and completely seal the clamping opening, the arc pull rods 5 can be separated from the monitoring range of the proximity switch 11, and the proximity switch 11 can control the telescopic hydraulic cylinder 8 to stop. In the process of opening the clamping opening by the two lock tongues 4, the connecting block 9 is driven to slide along the guide rail 10 by the telescopic rod of the telescopic hydraulic cylinder 8, the connecting block 9 drives the two arc-shaped pull rods 5 to move, when the two arc-shaped pull rods 5 drive the two lock tongues 4 to slide along the arc-shaped gaskets 7 and completely open the clamping opening, the arc-shaped pull rods 5 can enter the monitoring range of the proximity switch 11, and the proximity switch 11 can control the telescopic hydraulic cylinder 8 to stop. That is, when the arc-shaped pull rod 5 is separated from the monitoring range of the proximity switch 11, and when the arc-shaped pull rod 5 enters the monitoring range of the proximity switch 11, the proximity switch 11 controls the telescopic hydraulic cylinder 8 to stop. Therefore, the locking and unlocking operation of the lock tongue 4 is formed, on one hand, the two lock tongues 4 are prevented from being damaged and misplaced due to the fact that the abutting ends of the two lock tongues 4 are excessively extruded, and on the other hand, the automatic closing telescopic mechanism can improve the convenience of operation.
The working principle of the drill rod bearing assembly for the derrick racking platform provided in this embodiment is that after the drill rod 12 enters the drill rod bearing assembly, the shrinkage connection part of the drill rod 12 abuts against the bearing part 31 of the drill rod adapter 3. The two lock bolts 4 are driven by the telescopic hydraulic cylinder 8 to close the clamping opening, so that a clamping round cavity is formed. If the drill rod 12 is in an inclined state during the closing process, the two lock bolts 4 can straighten the drill rod 12, so that the drill rod 12 is vertical. After the drill rod 12 is placed at the designated position, the two lock bolts 4 are driven by the telescopic hydraulic cylinder 8 to open the clamping opening, and the bearing part 31 of the drill rod adapter 3 is separated from the shrinkage connecting part of the drill rod 12.
