Specific embodiment
Referring to Fig.1, oil pumping machine unloading device is welded in pumping unit shelf, when being unloaded, first by shutdown of pumping machine,
Control cabinet switch is allocated to manually, and pinning pumping unit descending button moves up ballast box, when moving to the bottom of the counterweight and feel trim actuator
When upper end is concordant, unloading fork 28 is put down, pinning pumping unit uplink button moves down ballast box, until falling on unloading fork 28, tightly
Urgent optical-rod clamp above wellhead polish rod packing box is pasted, pins unloading fork uplink button, motor 11 starts at this time, and torque successively leads to
Shaft coupling 12, thrust bearing assembl 14, lead screw 21, hoisting nut 22 are crossed, under the action of torque, unloading frame 25 passes through guide pad
33 cooperation 31 upward slidings of guide rail, drive unloading fork 28 and ballast box to move up, hanging rope relaxation, removes polished rod eye, i.e., later before making
Oil pumping machine unloading process is completed, whole process load belt is non-slip, and noise is met the requirements of the standard.
When carrying out extension load, under shutdown of pumping machine state, control cabinet switch is allocated to manually, whether checks unloading fork 28
Ballast box is ask to be in unloading 28 upper level positions of fork, as do not pinned unloading 28 uplink buttons of fork if high-order, motor 11 is opened at this time
Dynamic, torque passes sequentially through shaft coupling 12, thrust bearing assembl 14, lead screw 21, hoisting nut 22, under the action of torque, unloading
Frame 25 by guide pad 33 cooperate 31 upward sliding of guide rail, drive unloading fork 28 and ballast box move up to a high position, by polished rod eye with
Polished rod connection, hanging rope before tensing are close to the urgent optical-rod clamp in polished rod eye top position, pin unloading 28 descending buttons of fork, motor
11 reversions, torque passes sequentially through shaft coupling 12, thrust bearing assembl 14, lead screw 21, hoisting nut 22, in torque and ballast box
Under gravity, unloading frame 25 cooperates 31 slide downward of guide rail by guide pad 33, drives unloading fork 28 and ballast box to move down, makes
Optical-rod clamp on polished rod stuffing box leaves packing box, and load belt stress is tensioned at this time, removes the polished rod on polished rod stuffing box
Clamp, pinning pumping unit descending button, to make to move to its bottom on ballast box concordant with feel trim actuator upper end, packs up unloading fork 28, complete
At load process is hung, whole process load belt is non-slip, and noise is met the requirements of the standard.
In a preferred embodiment, nut baffle 23 is set in the parallel side of hoisting nut 22, nut baffle 23 is fixed
It is connected to 25 top of unloading frame, further strengthens the fixing intensity of hoisting nut 22, is filled by large torque to the offer of unloading frame 25
The lifting force of foot.
Reinforcing rib 29 is connect with unloading 28 eccentric rotaries of fork, keeps unloading 28 folding and unfoldings of fork convenient, simple.
25 inside top of unloading frame is equipped with top gusset 24, and bottom inside is equipped with bottom gusset 30, improves unloading frame 25
Integral strength, conducive to the realization of unloading.
Sheave 26 is arranged in 25 back plate centerline of unloading frame, and conductor rope nut 27 is arranged at unloading 28 central upper portion lines of fork,
Wirerope is sequentially connected with sheave 26 and conductor rope nut 27, and when loosening wirerope, unloading fork 28 leans on eccentric structure and gravity
Automatically put down, when tense wire rope, unloading fork 28 be stowed away come, whole process do not need personnel ascend a height folding and unfolding unloading fork 28,
It is more safe and simple.
Travel switch assembly 32 is set at 31 both ends of guide rail, when 25 upstream or downstream of unloading frame to travel switch assembly
At 32, motor 11 then stops working, and is conducive to the effective protection to lead screw 21 and motor 11.
