Abstract

A pumping unit balance weight moving device comprises a pumping unit crank and a pumping unit balance weight. The pumping unit balance weight is mounted on the pumping unit crank, a pushing nut is fixed onto the pumping unit crank by a fixing screw, female threads are arranged on the pushing nut, male threads are disposed on a pushing screw and screwed with the female threads on the pushing nut, and the front end of the pushing screw contacts with the pumping unit balance weight so that the balance weight can be moved by rotating the pushing screw. Accordingly, the pumping unit balance weight moving device saves time and labor, is low in labor intensity of operating workers, avoids dangers during operation, can be used for conveniently and quickly moving the pumping unit balance weight to a required position without affecting work schedule, is short in overhaul time of a pumping unit and delaying time for production, and reduces influence of balance adjustment to yield of an oil well.

Description

Balance of well pumping unit piece mobile device

Technical field

The utility model is the device of using on a kind of oil-field oil pumper, is a kind of balance of well pumping unit piece mobile device.

Background technology

The balance weight of oil pumper needs often to adjust the position, balance requirement in the time of could satisfying the upper and lower stroke of oil pumper, the position of adjusting balance weight need move to the balance weight of several tons of weights the another one position, the method of present on-the-spot mobile balanced block is, unload loose balance weight fixed screw earlier, prize balance weight with crowbar again, fastening again balance weight fixed screw.Because balance weight has several tons of weights, therefore, prize very slow, effort, the operator is dangerous big, causes personal injury easily, and the shutdown of pumping machine time is long, and the load affair is produced, and influences oil well output.

Summary of the invention

The purpose of this utility model is a kind of balance of well pumping unit piece mobile device of design, utilizes this balance of well pumping unit piece mobile device, can easily and efficiently the balance of well pumping unit piece be moved to the position that needs.

The purpose of this utility model is achieved in that and comprises oil pumping machine crank, balance of well pumping unit piece, the balance of well pumping unit piece is installed on the oil pumping machine crank, passing nut is fixed on the oil pumping machine crank by hold-down screw, pass on the nut box thread is arranged, pass on the screw rod male thread is arranged, the male thread of passing on the screw rod screws with the box thread of passing on the nut, passes screw front end and contacts with the balance of well pumping unit piece.

The beneficial effects of the utility model are: just energy mobile balanced block of screw rod is passed in rotation; time saving and energy saving; operator's labour intensity is low; be safe from danger during operation, utilize this balance of well pumping unit piece mobile device, can easily and efficiently the balance of well pumping unit piece be moved to the position that needs; do not influence job schedule; the shutdown of pumping machine time is short, and the load affair production time is short, has reduced the oil well output because of the balancing influence.

Description of drawings

Fig. 1 is the assembling drawing of the utility model embodiment.

The specific embodiment

Below in conjunction with Fig. 1 the utility model embodiment is described.

As seen from the figure, the utility model comprises oil pumping machine crank 1, hold-down screw 2, passes nut 3, passes screw rod 4, balance of well pumping unit piece 5, balance of well pumping unit piece 5 is installed on the oil pumping machine crank 1, passing nut 3 is fixed on the oil pumping machine crank 1 by hold-down screw 2, pass on the nut 3 box thread is arranged, passing on the screw rod 4 has male thread, and the male thread of passing on the screw rod 4 screws with the box thread of passing on the nut 3, passes screw rod 4 front ends and contacts with balance of well pumping unit piece 5.

During use, install hold-down screw 2 earlier, pass nut 3, pass screw rod 4, after unclamp the balance weight set bolt, screw rod 4 is passed in rotation, the motive force of passing screw rod 4 acts on the balance of well pumping unit piece 5, and balance of well pumping unit piece 5 is moved, and balance of well pumping unit piece 5 is moved to the position that needs.
