Abstract
The utility model relates to mechanical devices in the oil drilling and production industry, and provides a device preventing bolts of a crank pin from being inversely buckled. The device comprises a concave plate, a circular plate is arranged on the concave plate, a hole is formed in the circular plate on the concave plate, the bolts are arranged on the circular plate, and the bolts are in threaded connection with the circular plate. The device is simple in structure, ingenious in design and conception, convenient to use and maintain, and capable of effectively preventing the bolts of the crank pin from being inversely buckled and avoiding production accidents.
Description
Technical field
The utility model relates to petroleum drilling and mining industry mechanical device.
Background technique
Pumping unit is in actual production, crank pins is the vitals of pumping unit, because of crank pins bolt back-off, causes crank pins to deviate from from crank hole, cause pumping unit to turn over the accidents such as machine, oil well stopping production, cause irremediable economic loss to pumping unit and crude oil production.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of new technical thought for the deficiencies in the prior art.The utility model, by fixed crank pin bolt, reaches the object that prevents crank pins bolt back-off.
The technological scheme that the utility model provides is:
Crank pins bolt reverse fixation preventing device, comprises and the notch board of spill on notch board, is provided with circular plectane, on notch board, plectane place is hole, is provided with bolt on plectane, between bolt and plectane, is threaded.
Concrete, on the sidewall of notch board both sides, be provided with bolt, between bolt and sidewall, be threaded.
Preferably, between bolt and sidewall, be provided with pad.
Concrete, between bolt and plectane, be provided with cushion block.
The utility model is simple in structure, and design concept is ingenious, easy to use, is convenient to safeguard, can effectively prevent crank pins bolt back-off, avoids production development accident.

Fig. 1 is the utility model mounting structure schematic diagram.
Fig. 2 is the utility model structural representation.
Fig. 3 is the structural representation of described crank.
1 notch board 2 bolt 3 pad 4 bolt 5 plectane 6 crank 7 crown type nuts
8 cushion blocks.
Embodiment
As shown in the figure, crank pins bolt reverse fixation preventing device comprises the notch board of spill.On notch board, be provided with circular plectane, on notch board, plectane place is hole, makes plectane can be enclosed within the crown type nut of crank pins end.On plectane, be provided with bolt, between bolt and plectane, be provided with cushion block, between bolt and plectane, be threaded.Or by cushion block be fixedly installed with plectane on, between bolt and cushion block, be threaded.
On the sidewall of notch board both sides, be provided with bolt, between bolt and sidewall, be threaded.Between bolt and sidewall, be provided with pad.Or pad is fixed on sidewall, between bolt and pad, be threaded.
The utility model plectane is enclosed within on the crown type nut of crank pins end, makes this device in crank pit.Then by the bolt rotation on sidewall, make bolt withstand crank pit.In addition, also can improve applicability of the present utility model, make the utility model can use the crank pit of multiple size.
Then by the bolt rotation on plectane, make bolt withstand crown type nut.The utility model can be used the crank pins bolt of multiple size.Can prevent the reversing of crank pins bolt, back-off phenomenon can not occur, avoided crank pins to deviate from the generation of accident simultaneously.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characteristics is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
