Abstract
The utility model relates to a walking-beam pumping unit, and in particular to a tool for adjusting the counter balance of the beam pumping unit. The tool comprises a screw rod, a screw head, a gear and a nut, wherein the screw head is arranged at one end of the screw rod; threads are formed at the other end of the screw rod; the one end of the screw rod with the threads is flat; a middle hole of the gear is matched with the screw rod; and the nut is positioned on the outer side of the gear and in threaded connection with the screw rod. The tool provided by the utility model is time-saving and labor-saving, is simple and convenient to operate, has low labor intensity, and is safe when being operated.
Description
Technical field
The utility model relates to beam pumping unit, relates in particular to the instrument of adjustment balance of well pumping unit piece.
Background technology
The balanced ratio of beam pumping unit along with the variation of extraction fluidity matter and the variation of motor load, is regular variation, that is to say that the adjustment of the balanced ratio of beam pumping unit is a regular job.The position of adjustment balance weight needs the balancing weight of several tons of weights is moved to the another one position.Existing adjustment work can be divided into three kinds of methods:
1, oil pumper is stopped behind the position and direction of needs adjustment, unload loose fixed screw after, the people stands on the plane of crank that width is 120mm, operates with crowbar, and is very dangerous.The on-the-spot oil pumper that uses of producing well is exposed to the weather throughout the year in the open air, makes on the crank plane corrosion serious; Balancing weight moves very difficulty; And the plane is overhead more than 2300-2700mm on the crank, and operating personnel's probability that falls of slipping is very big, and the annual incident that all has operating personnel to fall takes place.
2, the balancing weight fixed screw is unloaded pine after, carry out swinging operation with crane, thus, a series of troubles of bringing, as: 1) can not adjust operation at any time; 2) the vehicle cost is high.
3, use operating platform, the crank operation.Since the determining positions of the connecting rod of oil pumper can not balancing weight be adjusted to correct position.
Summary of the invention
The purpose of the utility model just provides a kind of beam pumping unit adjustment balance and uses instrument, utilizes this instrument, can conveniently the oil pumper balancing weight be moved to the position that needs.
The technical scheme that the utility model provides is:
Beam pumping unit adjustment balance is used instrument, is made up of screw rod, spiral shell head, gear, nut, and an end of screw rod is the spiral shell head; The other end of screw rod is a screw thread; The threaded end of screw rod is tabular, and the interstitial hole and the screw rod of gear are complementary, and the outside that nut is positioned at gear is connected with screw flight.
Preferably, the modulus of lock dog upper rack is the same on the modulus of gear and the beam type oil pumping machine crank.
The technical scheme that the utility model provides only need be used spanner or other instruments, and locking spiral shell head also is rotated, and relies on the transmission self-balanced upper rotary of gear and crank upper rack.The utility model is time saving and energy saving, and is easy and simple to handle, and labour intensity is low, is safe from danger during operation.The technical scheme of utilizing the utility model to provide can move to the position that needs with balancing weight easily and efficiently, does not influence job schedule, the shutdown of pumping machine time.

Fig. 4 is the left view of beam pumping unit adjustment balance with instrument.
1 balancing weight, 2 cranks, 3 lock dogs, 4 screw rods, 5 spiral shell heads, 6 gears, 7 nuts.
The specific embodiment
As shown in the figure; Beam pumping unit adjustment balance is used instrument, is made up of screw rod, spiral shell head, gear, nut, and an end of screw rod is the spiral shell head; The other end of screw rod is a screw thread; The threaded end of screw rod is tabular, and the interstitial hole and the screw rod of gear are complementary, and the outside that nut is positioned at gear is connected with screw flight.
The modulus of lock dog upper rack is the same on the modulus of gear and the beam type oil pumping machine crank.
During use, lock dog is taken off, beam pumping unit is adjusted balance insert the position that lock dog occupies on the balancing weight from the outside, then geared sleeve is got on, fixedly tighten with nut at last with the first end of the spiral shell of instrument.Operating personnel clamp the spiral shell head with spanner then, rotate the spiral shell head as required and get final product.Balancing weight is adjusted to the position that needs, beam pumping unit is adjusted balance take off, lock dog is put and fixed with instrument.
Claims (2)
1. beam pumping unit adjustment balance is used instrument; It is characterized in that be made up of screw rod, spiral shell head, gear, nut, an end of screw rod is the spiral shell head; The other end of screw rod is a screw thread; The threaded end of screw rod is tabular, and the interstitial hole and the screw rod of gear are complementary, and the outside that nut is positioned at gear is connected with screw flight.
2. use instrument according to the said beam pumping unit of claim 1 adjustment balance, it is characterized in that, the modulus of lock dog upper rack is the same on the modulus of gear and the beam type oil pumping machine crank.
