Abstract
The utility model relates to a hydraulic drill collar fork used for a petroleum drill and a geophysical prospecting drill. The hydraulic drill collar fork comprises a collar fork 1, a collar fork seat 2 and a hydraulic cylinder 4. The collar fork 1 is arranged on the colllar fork seat 2 and the hydraulic cylinder 4 is connected with the collar fork 1. The collar fork seat 2 is provided with a slide track to replace the common fork manual operation.Thus the degree of automation and the operating efficiency of the drill can be improved.Meanwhile, the operation is more accurate.
Description
Affiliated field
The utility model relates to a kind of instrument of oil, the use of geology physical prospecting rig, specifically, is the shackle fork that surges.
Background technology
At present to connect what use mostly when changing drilling rod be manual common fork to the physical prospecting rig, needs when this fork uses flatly to align that the back is manual puts into fork with what drilling rod cooperate fork, and rig automation degree and operating efficiency are lower.
Technology contents
The purpose of this utility model is to provide a kind of replacement common fork manual operations, thereby can improve the shackle fork that surges of the automaticity and the operating efficiency of rig.
The utility model is achieved in that and comprises and fork 1, fork seat 2, oil cylinder 4 are contained on the fork seat 2 at fork 1 that oil cylinder 4 is connected with fork 1.
The utility model also adopts following technical scheme:
On the fork seat 2 slideway is arranged.
Advantage of the present utility model is: replace common fork manual operations, thereby can improve the automaticity and the operating efficiency of rig, make also that simultaneously operation is more accurate.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
As shown in drawings, fork 1 is installed on the fork seat 2, shackle on the drilling rod 3 is flat roughly align after, hydraulic jack 4 stretches out, promoting fork 1, to move the shackle of blocking on the drilling rod 3 along fork seat 2 slideways flat, after the rig shackle, and hydraulic jack 4 withdrawals, drive fork 1 and return original position, finish the chucking of drilling rod and unclamp.
The shackle fork that surges operation is used by the desert deep drilling rig of my unit, and effect is very desirable, and drilling rod cooperates flat roughly the aligning of fork to operate during use, and therefore, service efficiency is very high, and the automaticity raising facilitation to rig is very big simultaneously.
Claims (2)
1. the shackle fork that surges comprises fork (1), fork seat (2), oil cylinder (4), and it is characterized in that: fork (1) is contained on the fork seat (2), and oil cylinder (4) is connected with fork (1).
2. the shackle fork that surges according to claim 1 is characterized in that: the fork seat has slideway on (2).
