Abstract
A pumping unit balance block locking and moving device comprises a shaft (1), a gasket (2), a nut (3), a gear (5), a locking tooth (6) and a bolt (7). The shaft (1) of the pumping unit balance block locking and moving device passes through a central hole I (B) of the gear (5), the bolt (7) penetrates through a central hole II (C) of the locking tooth (6) and enables the locking tooth (6) to be fixed to the right end of the shaft (1), and the gasket (2) is arranged at the right end of the shaft (1) and fixed through the nut (3). The pumping unit balance block locking and moving device is simple in structure and convenient to operate. A crank stops in a horizontal position when the balance block is moved, only a locking plate and a locking plate fixing bolt are detached, a shaft end is rotated through a pipe wrench and a spanner, and therefore the gear can be driven to rotate on a rack of the crank, and the balance block can be driven to move. The influences of a connecting rod are completely avoided, the risk that the balance block falls when an existing balance block moving tool is used is eliminated, the operating difficulty of workers is lowered, and the aim of saving time and labor is achieved.
Description
Technical field
The utility model relates to oil-field oil pumper accessory and adjustment instrument, specifically a kind of counter weight of beam unit locking shifter.
Background technology
Existing counter weight of beam unit lock dog can only be locked balance weight; while utilizing existing balance weight Move tool mobile balanced block; if lock dog needs wide-angle to shut down while stopped by connecting rod, balance weight lock dog is installed; have that secondary opens, the problem of stop pumping oil machine length consuming time; and the risk that exists balance weight to drop in said process; the balance weight lock dog risk that balance weight drops of again dismantling before mobile balanced block is larger, and this is also the defect in the use procedure of existing balance weight Move tool.Existing " Multifunctional locking block of balancing block of sucker ", the patent No.: ZL01250722.9, needs whole outer moving owing to moving aid as balance weight, exists and contacts with pumping unit connecting bar, is even blocked problem; Again due to pumping unit connecting bar and crank and balance weight spacing little, workman's operative skill is had relatively high expectations, on-the-spot application is restricted.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of counter weight of beam unit locking shifter is provided.
The technical solution of the utility model comprises: axle, pad, nut, gear, lock tooth, bolt.The axle of its counter weight of beam unit locking shifter is by gear center hole I, will lock tooth and axle right-hand member is fixed by bolt through the centre bore II of lock tooth, and the right-hand member of axle is equipped with pad, and is fixed by nut.
Axle in above-mentioned counter weight of beam unit locking shifter is two-stage hierarchic structure, and left half is provided with external screw thread, and the threaded exterior end side of being provided with lacks, and right-hand member is 4～6 limit square toes.
Tooth module on gear in above-mentioned counter weight of beam unit locking shifter equates with the tooth module on crank,
Centre bore I is provided with 4～6 limit square holes outward, and the size side of being greater than lacks.
Lock tooth bottom in above-mentioned counter weight of beam unit locking shifter is provided with tooth bar, and the tooth module of tooth bar equates with the tooth module on crank, and top is semi-circular structure.
The beneficial effects of the utility model are: simple in structure, easy to operate, when mobile balanced block, crank is parked in horizontal level, only dismantle locking plate and locking plate set bolt, by pipe wrench, spanner rotary shaft end, just can on crank tooth bar, rotate by driven gear, and then band dynamic balance weight moves.Thoroughly avoid connecting rod impact, eliminated the risk that in the use procedure of existing balance weight Move tool, balance weight drops, reduced workman's operation easier, reached time saving and energy saving object.
