Technical Field

[0001] This utility model relates to the field of pipeline drilling technology, and in particular to a shock absorption device for pipeline drilling. Background Technology

[0002] Casing drilling refers to the use of casing instead of drill pipe to apply torque and drilling pressure to the drill bit, enabling the drill bit to rotate and drill. The entire drilling process no longer uses drill pipe, drill collars, etc. The drill bit is retrieved using a wire rope and raised and lowered within the casing, thus achieving drill bit and drilling tool changes without lifting the drill string.

[0003] In existing technologies, during pipeline drilling, the pipeline is prone to violent shaking due to the action of the drill bit inside the pipeline, which may cause the pipeline to shift in position and affect the quality and accuracy of drilling. Utility Model Content

Therefore, a shock-absorbing device for pipeline drilling is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: It includes a main structure and a shock-absorbing structure; the shock-absorbing structure includes a shock-absorbing base, a set of mounting grooves extending through the interior of the shock-absorbing base, a shock-absorbing pad fixedly installed at the bottom of the shock-absorbing base, a set of mounting plates fixedly installed on the outer wall of the shock-absorbing base, dampers inserted into the interior of each of the mounting grooves, a set of limiting blocks fixedly installed on the outer wall of each of the dampers, two sets of limiting blocks respectively disposed on the inner and outer walls of the shock-absorbing base, a fixing block fixedly installed at one end of each of the dampers, a rubber sleeve fixedly installed on one side of each of the fixing blocks, and a shock-absorbing spring sleeved on the outer wall of each of the dampers.

[0008] Preferably, a set of connecting blocks is fixedly installed on the top of the shock-absorbing base, and a fixing ring is fixedly installed between the set of connecting blocks.

[0009] Preferably, a fixing bolt is inserted through the inside of the fixing ring, and the fixing bolt is threadedly connected to the fixing ring.

[0010] Preferably, the main structure includes a ground, a pipe body is inserted inside the ground, and a shock-absorbing sleeve is fitted onto the outer wall of the pipe body.
