Description

The twin shaft pincers

Technical field

The utility model provides a kind of instrument, especially a kind of field produces instrument.

Background technology

In oilfield process, mainly adopt pumping production.Need to seal between sucker rod on the oil pumper and the pit shaft with packing box.Packing in the packing box needs periodic replacement because of the wearing and tearing in using.During replacing, shutdown of pumping machine need be parked in the polished rod eye on the oil pumper from the about 500 millimeters places of packing box; brake then; lay down on packing box pressure cap and the packing box Glan, hang over packing box pressure cap and Glan on the polished rod eye with rope after, change the operation of packing.But because in the actual production, most inefficacy of the brake on the oil pumper or braking effect are not good, during shutdown, desirable position is often departed from the position of polished rod eye.At this moment, need the first pipe wrench be stuck on the sucker rod, thereby packing box pressure cap and Glan are kept off above packing box, another people changes the operation of packing.The first operation makes mistakes slightly, will injure another people by a crashing object, and is both dangerous, and it is also many to choose, inefficiency.

Summary of the invention

The utility model wants the technical solution problem to be, provides a kind of twin shaft pincers, the security when changing packing to improve.

The utility model is to realize like this, the twin shaft pincers, it has handle and another handle, the handle front end has fixing pincers handle, on the fixing pincers handle axle bed and another axle bed are arranged, the front end of another handle has the adjustable clamp handle, the adjustable clamp handle is hinged on the axle bed by bearing pin, another adjustable clamp handle is hinged on another axle bed by another bearing pin, two adjustable clamp handles mesh together by the sector gear on both opposite faces, fixing pincers handle, another adjustable clamp handle front end has binding clip respectively, flexible block is arranged respectively in the binding clip, deep-slotted chip breaker is arranged respectively on the opposite face of two flexible blocks, on fixing pincers handle, be hinged with ratchet by the 3rd bearing pin, on the adjustable clamp handle latch is arranged, between ratchet and the fixing pincers handle extension spring is arranged.

Adopt the twin shaft pincers of said structure, easy to use, handling safety, a people will finish all working of changing packing, high efficiency.And rational in infrastructure, use reliable.

Description of drawings

Fig. 1 is the schematic diagram of the utility model structure.

Fig. 2 is the B-B profile of Fig. 1.

Fig. 3 is the A-A profile of Fig. 1.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model and operation principle.

As shown in drawings, the twin shaft pincers of the utility model, it has handle 12 and another handle 11, handle 12 front ends have fixing pincers handle 14, on the fixing pincers handle axle bed 13 and another axle bed 15 are arranged, the front end of another handle 11 has adjustable clamp handle 8, the adjustable clamp handle is hinged on the axle bed 13 by bearing pin 7, another adjustable clamp handle 5 is hinged on another axle bed 15 by another bearing pin 4, two adjustable clamp handles mesh together by the sector gear on both opposite faces 6, fixing pincers handle, another adjustable clamp handle front end has binding clip 2 respectively, have respectively in the binding clip on the opposite face of flexible block 3, two flexible blocks deep-slotted chip breaker 16 is arranged respectively, on fixing pincers handle 14, be hinged with ratchet 9 by the 3rd bearing pin 17, latch 18 is arranged on the adjustable clamp handle 8, between ratchet and the fixing pincers handle extension spring 10 is arranged.

The binding clip of described handle 12, fixing pincers handle 14, axle bed 13 and another axle bed 15, fixing pincers handle front end can be made one.Described another handle 11, adjustable clamp handle 8 can be made one.The binding clip of described another adjustable clamp handle 5, another adjustable clamp handle front end can be made one.

During use, oil pumper is come to a complete stop and can operate, polished rod eye can be parked in does not influence the optional position of changing the packing operation.Pressure cap on the packing box and Glan are unloaded.Hold fixed handle, make the adjustable clamp handle by the sector gear on the two adjustable clamp handle opposite faces, outwards open the front portion that drives another adjustable clamp handle, the binding clip of another adjustable clamp handle front end also just opens, to move on pressure cap and the Glan then, flexible block in the binding clip is stuck on the sucker rod below pressure cap and the Glan.In release handle, ratchet is stuck with latch 18 on the adjustable clamp handle 8 under the pulling force effect of extension spring, realizes the location of binding clip, with pressure cap and Glan retaining above these twin shaft pincers.Staff can break away from handle, changes the operation of packing.After replacing is finished, hold fixed handle once more, latch and ratchet break away from.These twin shaft pincers are taken off from sucker rod, put down pressure cap and Glan, be fixed on the packing box, can finish the operation of whole replacing packing.

Front end at described binding clip 2 has guided plate 1 respectively.Guided plate outwards opens.Guided plate plays guiding, guide effect, the convenience in the time of can improving binding clip and be stuck on the sucker rod.
