Abstract
The utility model discloses a back -up tong arm relocation mechanism, including back -up tong arm endotheca, back -up tong arm overcoat, adjust jar, spring, overhead gage, baffle down, the back -up tong is connected with back -up tong arm endotheca, adjusts the cylinder body or the jar pole of jar and installs in back -up tong arm overcoat through a round pin axle, the overhead gage setting is at back -up tong arm endotheca top, adjusts the jar and passes the overhead gage center, lower baffle is fixed and is being adjusted the jar below, the spring setting is at the overhead gage under and between the baffle. During the operation, through the flexible position of controlling the back -up tong arm of control regulation jar, locking after the regulation is accomplished. The utility model discloses a design of mechanism is accomplished with the combination of spring to the pneumatic cylinder, and its action process is stable, the fault rate is low, easy operation, and operating personnel only needs operation control panel can realize the action of mechanism.
Description
Technical field
The utility model relates to oil-well rig top and drives and the accessory field in unit head, unloads in drilling rod process, can make the mechanism that back-up tong moves up and down and floats on being exactly specifically.
Background technology
The back-up tong arm of existing back-up tong is generally be hinged in pipe processor, regulates highly by moved by hand back-up tong.Due to the thick heaviness of its structure, need to rely on some actuating units to coordinate adjustment back-up tong position.After unclamping back-up tong, keep back-up tong and back-up tong arm not to tilt by wear-resistant block.Add operating time and manpower, consumptive material wear-resistant block adds cost.
For above problem, be necessary to provide a kind of structure simple, back-up tong arm mechanism easy to adjust.
Summary of the invention
The utility model provides a kind of back-up tong arm relocation mechanism, and this mechanism structure is simple, easy to adjust, realizes the mechanization moved up and down, and can holding position on one's own account, realizes the function of floating, does not need to consume wear-resistant block.
The technical scheme in the invention for solving the technical problem is: a kind of back-up tong arm relocation mechanism, comprise back-up tong arm inner sleeve 1, back-up tong arm overcoat 2, regulate cylinder 3, spring 4, overhead gage 5, lower baffle plate 6, back-up tong is connected with back-up tong arm inner sleeve 1, the cylinder body of cylinder 3 or cylinder bar is regulated to be arranged in back-up tong arm overcoat 2 by a bearing pin, overhead gage 5 is arranged on back-up tong arm inner sleeve 1 top, regulate cylinder 3 through overhead gage 5 center, lower baffle plate 6 is fixed on and regulates cylinder 3 bottom, and spring 4 is arranged between overhead gage 5 and lower baffle plate 6.During operation, by controlling to adjust the position of the extension and contraction control back-up tong arm of cylinder 3, regulate rear locking.In use procedure when axial runout appears in drilling rod or main shaft, back-up tong arm can realize adjustment by pulling back-up tong arm inner sleeve 1, and this is completed by the compression of spring 4 or release, can not produce impact fluid cylinder.
As optimization, described back-up tong arm inner sleeve 1, the main body of back-up tong arm overcoat 2 are rectangular tube or pipe.
As optimization, described adjustment cylinder 3 is hydraulic cylinder or cylinder.
As optimization, described back-up tong arm inner sleeve 1, back-up tong arm overcoat 2 are all provided with connecting hole or installing hole.
As optimization, described lower baffle plate passes through pinned connection with regulating cylinder 3.
The beneficial effects of the utility model are: compared with prior art, the utility model completes the design of mechanism by the combination of hydraulic cylinder and spring, its course of action is stable, failure rate is low, simple to operate, operating personnel only need operation control panel can realize the action of mechanism.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model general structure.
Fig. 2 is left view of the present utility model.
Wherein, 1 back-up tong arm inner sleeve, 2 back-up tong arm overcoats, 3 regulate cylinder, 4 springs, 5 overhead gages, 6 lower baffle plates.
Detailed description of the invention
As shown in Figure 1 and Figure 2 in embodiment, a kind of back-up tong arm relocation mechanism, comprise back-up tong arm inner sleeve 1, back-up tong arm overcoat 2, regulate cylinder 3, spring 4, overhead gage 5, lower baffle plate 6, back-up tong is connected with back-up tong arm inner sleeve 1, regulate the cylinder body of cylinder 3 or cylinder bar to be arranged in back-up tong arm overcoat 2 by a bearing pin, overhead gage 5 is arranged on back-up tong arm inner sleeve 1 top, regulates cylinder 3 through overhead gage 5 center, lower baffle plate 6 is fixed on and regulates cylinder 3 bottom, and spring 4 is arranged between overhead gage 5 and lower baffle plate 6.As optimization, described back-up tong arm inner sleeve 1, the main body of back-up tong arm overcoat 2 are rectangular tube or pipe.Cylinder 3 is regulated to be hydraulic cylinder or cylinder.Back-up tong arm inner sleeve 1, back-up tong arm overcoat 2 are all provided with connecting hole or installing hole.Lower baffle plate passes through pinned connection with regulating cylinder 3.
During operation, by controlling to adjust the position of the extension and contraction control back-up tong arm of cylinder 3, regulate rear locking.In use procedure when axial runout appears in drilling rod or main shaft, back-up tong arm can realize adjustment by pulling back-up tong arm inner sleeve 1, and this is completed by the compression of spring 4 or release, can not produce impact fluid cylinder.
Above-mentioned detailed description of the invention is only concrete case of the present invention; scope of patent protection of the present invention includes but not limited to product form and the style of above-mentioned detailed description of the invention; any meet claims of the present invention a kind of back-up tong arm relocation mechanism and any person of an ordinary skill in the technical field to its suitable change done or modification, all should fall into scope of patent protection of the present utility model.
