Description
Technical field
The utility model belongs to petroleum and natural gas drilling well top and pushes the clamping device that is used for shackle in the drilling rig, specifically, is a kind of top-driving drilling device multi-position two-way floating vice.
Background technology
Back-up tong is an ingredient important in the top-drive drilling.Top-drive drilling is a kind of novel oil drilling equipment, top driving device moves to rotary power on the top of rig, workover rig water tap, drive drill string rotating, be equipped with a set of tubes treating apparatus simultaneously, self have last shackle function, can any height in derrick carry out the shackle operation.The function of last shackle is to clamp drilling rod by back-up tong, and main motor rotation realizes.
As everyone knows, when connecting the last shackle operation of drill string, along with screwing of screw thread, joint can produce axial motion, this will require the suspension of back-up tong that float function is arranged, axially-movable in the time of can screwing with screw thread moves up and down, otherwise will cause the damage of the form of thread when screw thread screws, and shortens the application life of drilling rod.
The employed well head Power Tong of conventional drilling operation because its suspension system adopts elongated steel cable, can satisfy the requirement of shackle on the drillng operation floating in a big way.But for top-drive drilling, its back-up tong system is the part of top driving device, and its structure has very big rigidity, must consider the relocation mechanism of design back-up tong in addition.
The back-up tong of existing top driving device all floats with respect to the back-up tong bracket, and only is downward unidirectional floating.And the back-up tong bracket all is to be designed to stationary structure, and bracket itself can not the shift position, and therefore, the back-up tong of existing top driving device or fix with bracket can not the shift position, though or can move, just no longer include float function after mobile.Therefore, existing back-up tong is for example gone up the shackle operation to IBOP when being moved upwards up to the work of other positions, and its effect has been subjected to certain restriction.
Summary of the invention
It is a kind of simple in structure, multiple functional that the utility model purpose is to provide, a kind of easily top-driving drilling device multi-position two-way floating vice of on-the-spot working service.
The utility model is achieved in that and comprises hydraulic cylinder 1, back-up tong support 2, back-up tong bracket 3, rear end cap 4, piston 5, drive end bearing bracket 6, front die base 7, dental lamina 8, rear die base 9, front clamp body 10, preceding guide ring 11, back guide ring 12, back-up tong support 2 is located on the back-up tong bracket 3, rear end cap 4 is connected with drive end bearing bracket 6, between rear end cap 4 and the drive end bearing bracket 6 piston 5 is housed, be provided with dental lamina 8 between front die base 7 and the rear die base 9, front clamp body 10 is connected with rear die base 9, runs through spring 13 is housed in hydraulic cylinder 1.
The utility model also adopts following technical scheme:
At one of the upper design of back-up tong back-up tong bracket 3 independently, slide up and down along back-up tong support 2, move to any appointed positions, and be fixed on the back-up tong support 2 with pin in this position, back-up tong is suspended on the back-up tong bracket 3, slide up and down along support 2 with bracket 3, shackle is gone up in the operating position that moves to appointment.
Back-up tong and back-up tong bracket 3 are the spring 13 of two-way floating, and bracket 3 is suspended on back-up tong on the back-up tong support 2 by spring 13.
Guide ring 11, back guide ring 12 before the bottom of this device also is provided with.
Advantage of the present utility model is: be mainly used in top drilling well drive unit, clamp tool joint, realize drilling rod and push up the function of driving shackle on the protection joint.Can also upper and lower slip protect joint, manual and automatic stop cock valve with dismounting.Be characterized in: can move up and down the operating position of appointment, and two-way floating about after this fixed-site, dismounting protection joint and plug valve easy operating.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a contour structures schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, comprise hydraulic cylinder 1, back-up tong support 2, back-up tong bracket 3, rear end cap 4, piston 5, drive end bearing bracket 6, front die base 7, dental lamina 8, rear die base 9, front clamp body 10, preceding guide ring 11, back guide ring 12, at first, at one of the upper design of back-up tong back-up tong bracket 3 independently, can slide up and down along back-up tong support 2, move to any appointed positions, and be fixed on the back-up tong support 2 with pin in this position.Back-up tong is suspended on the back-up tong bracket 3, can slide up and down along support 2 with bracket 3, and shackle is gone up in the operating position that moves to any appointment.As shown in Figure 2, be designed between back-up tong and the back-up tong bracket 3 can two-way floating spring mechanism 13, bracket 3 is suspended on back-up tong on the back-up tong support 2 by spring mechanism 13.When bracket 3 was fixed on the support 2 a certain position, back-up tong can be realized floating of both direction up and down in this position.Thereby realized the two-way floating function of back-up tong at diverse location.
Unique design of the present utility model is independently back-up tong bracket 3, and back-up tong is connected with back-up tong bracket 3 by spring mechanism 13, and back-up tong can be with respect to back-up tong bracket two-way floating about in the of 3;
