Abstract
An oil pumping unit balance block fixing nut wrench comprises two positioning shafts, two adjusting shafts and a nut wrench body. An inner polygonal hole is arranged inside the nut wrench body, the positioning shafts are mounted on one side of the nut wrench body and positioned on the outer side of the polygonal hole, the lower portions of the positioning shafts and the adjusting shafts are in threaded connection, and the positioning shafts and the adjusting shafts are symmetrically mounted. When the nut wrench body sleeves a locking nut, the adjusting shafts support on a connecting nut, and the inner polygonal hole inside the nut wrench body is enabled not to be clamped on the connecting nut, so that the nut wrench body can demount the locking nut and then demount the connecting nut; the positioning shafts and the adjusting shafts can be mounted on an existing wrench, and reprocessing of a wrench is not needed, so that processing cost can be reduced.
Description
Technical field:
The utility model relates to the instrument of oil-field oil pumper mounting or dismounting use, is a kind of counter weight of beam unit hold-down nut spanner.
Background technology:
Oil-field oil pumper balance weight is connected on crank by bolt group, thread off in order to prevent the nut in bolt group, in bolt group, install locking nut additional, because locking nut and attaching nut fastening and dismounting simultaneously simultaneously, in the time of mounting nuts, first tighten attaching nut, tighten again split nut, when dismounting, first dismantle tight split nut, dismantle again attaching nut, but existing nut wrench easily blocks attaching nut in the time of the tight split nut of rotation, make it can not mount and dismount tight split nut, make troubles to installation and maintenance oil pumper, inefficiency, the course of work is long, work quality is poor, cause economic loss.Chinese patent 201120405473.1 " locknut wrench of oil pumping unit ", can address the above problem, but it will process one section of circular hole on spanner, need to thicken spanner size, can not on existing spanner, improve and form, need to again process new spanner, increase into written or printed documents and drop into.
Summary of the invention:
The purpose of this utility model is a kind of counter weight of beam unit hold-down nut spanner of design, is convenient to mount and dismount locking nut, and improves and form on existing spanner, reduces production costs.
The purpose of this utility model is achieved in that and comprises locating shaft, regulating shaft, nut spanner, there is inner polygon hole nut spanner inside, in the one side of nut spanner, locating shaft is installed, the outside of locating shaft in polygonal hole, the bottom of locating shaft is threaded with regulating shaft, two of locating shaft, the symmetrical installations of regulating shaft.
The beneficial effects of the utility model are: when nut spanner entangles locking nut, regulating shaft is supported on attaching nut, the inner polygon hole of nut spanner inside can be stuck on attaching nut, so, nut spanner can first be dismantled locking nut, rear dismounting attaching nut, and locating shaft, regulating shaft can be arranged on existing spanner, do not need processing spanner again, can reduce processing cost.
Brief description of the drawings:
Fig. 1 is the installation diagram of the utility model embodiment.
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention:
Describe below in conjunction with Fig. 1,2 couples of embodiment of the present utility model.
As seen from the figure, the example of executing of the utility model reality comprises locating shaft 1, regulating shaft 2, nut spanner 3, there is inner polygon hole 4 nut spanner 3 inside, and locating shaft 1 is installed in the one side of nut spanner 3, generally adopt welding manner that locating shaft 1 is arranged on nut spanner 3, the outside of locating shaft 1 in polygonal hole 4, the bottom of locating shaft 1 is threaded with regulating shaft 2, and two of locating shaft 1, the symmetrical installations of regulating shaft 2, also can install three, if install three, three on a circumference.
