Description
Technical field
The utility model belongs to pumping unit accessories field, more particularly to a kind of multi-functional from suspension type sucker rod suspension device.
Background technique
Polished rod eye, is the important component on pumping unit, function be on pumping unit horsehead hair plait and oil pumping
Bar is attached.In actual operation, disconnected de- or box cupling can occur under the collective effect of the factors such as eccentric wear, vibration for sucker rod de-
The phenomenon that button, brings very big difficulty to field production management, while increasing a large amount of production cost.In order to solve this problem,
There is a kind of polished rod eye that sucker rod can be forced to rotate automatically in the prior art, this device passes through guiding skewed slot and freewheel clutch
Effect sucker rod is rotated automatically solve the problems, such as eccentric wear, by the way that butterfly spring is arranged, solve to a certain extent
The problem of vibration, however, there are some defects for the device: although butterfly spring has, stroke is short, load weight, required space
It is small, be applied in combination conveniently, maintenance change the outfit easy, economic, highly-safe, long service life many advantages, such as, but this spring
Rigidity is very big, can still generate in the moment absorbed impact and largely vibrate, therefore, the effectiveness in vibration suppression of the device needs to be mentioned
It rises.
Utility model content
To solve the problems, such as that effectiveness in vibration suppression is poor in background technique, the utility model provides a kind of multi-functional from suspension type oil pumping
Bar suspension arrangement.
Technical solution provided by the utility model is: a kind of multi-functional from suspension type sucker rod suspension device, including shell, pressure
Lid, disc spring, disc spring pressing plate, carrying set and freewheel clutch, carrying set, disc spring pressing plate and disc spring are from top to bottom sequentially arranged at shell
In vivo, gland is bolted at the top of shell, and gland covers in the outside of carrying set to which the upper end to carrying set carries out
Righting, carrying set are mounted on disc spring pressing plate by thrust bearing, and the outside for carrying set is equipped with torque by freewheel clutch
Generator is provided with guiding skewed slot on the inside of the shell, is fixed on the outside of the torque generator and guiding skewed slot
With and can along guiding skewed slot sliding sliding block, further include sliding sleeve, the shell lower end is inserted into sliding sleeve, housing bottom and sliding sleeve
It is provided with support spring between bottom, the side of the shell and the side of sliding sleeve are symmetrically arranged that there are two for accommodating hair
The holding tank of plait.
Tank filler sleeve is provided on the gland.Shield for protecting hair plait is installed in the holding tank on the sliding sleeve
Plate, the lower end of backplate are fixedly connected on the inside of the holding tank on sliding sleeve, and the upper end of backplate is inserted into the holding tank on shell
It is interior.
The utility model has the following beneficial effects:
1, the utility model is provided with the lesser support spring of rigidity between shell and sliding sleeve, is pressed in the disc spring
The moment of contracting, support spring are compressed in advance, so that effectively buffering disc spring is further improved and subtracted by the impact of compression moment generation
Vibration effect.
2, backplate is provided in holding tank of the utility model on sliding sleeve, shell and sliding sleeve are opposite when sliding, backplate with
Hair plait is opposing stationary, to effectively prevent a mao plait abrasion.
3, the utility model is provided with tank filler sleeve on gland, and lubricant grease can be injected into shell by tank filler sleeve, can
Effectively extend the service life of device.
