However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-5 As shown, the oil production control device for the pumping unit includes a pumping unit walking beam 1 and a frame-type telescopic body 2. A counterweight 3 is inserted into the end of the frame-type telescopic body 2. A groove 4 is provided at the end of the pumping unit walking beam 1 to connect with the frame-type telescopic body 2. The groove 4 is horizontally positioned, and several columnar protrusions extending along the length of the pumping unit walking beam 1 on one side of the groove 4 penetrate the frame-type telescopic body 2. Figure 2 and Figure 3 The columnar protrusions on the inner wall of the slide 4 ensure that the frame-type telescopic body 2 can only slide along the length of the pumping unit walking beam 1, thus adjusting the balance of the pumping unit walking beam 1. Furthermore, by replacing the counterweights 3 of different sizes and weights, the weight of the frame-type telescopic body 2 can be easily adjusted. Combined with the sliding of the frame-type telescopic body 2 within the pumping unit walking beam 1, further adjustments to the balance of the pumping unit walking beam 1 can be achieved.

[0024] A guide rail 17 is fixedly installed at the top of the slide 4. A slide block 6 that slides along the length of the pumping unit walking beam 1 is inserted into the guide rail 17. A lead screw 7 that is parallel to the length of the pumping unit walking beam 1 and has a thread passing through the slide block 6 is rotatably connected inside the guide rail 17. By installing a servo motor of the prior art in the slide 4 to drive the lead screw 7 to rotate, the slide block 6 can slide along the length of the pumping unit walking beam 1 with the rotation of the lead screw 7 under the assistance of the guide rail 17.

[0025] The two winches 9 are fixedly installed at the bottom of the sliding seat 6, the center shafts of the two winches 9 are rigidly connected through the shaft coupler, and one end of the winding rope on the center shafts of the two winches 9 is fixedly installed in the traction seat 5 at the leading end of the frame telescopic body 2. Similarly, another servo motor is installed on the sliding seat 6 to drive the center shafts of the two winches 9 to rotate, so that the winding rope can be released or wound. In combination with Figure 2 and Figure 3 When the sliding seat 6 is located at the left side of the leading end of the frame telescopic body 2, the winding rope wound by the winch 9 can realize the left movement of the frame telescopic body 2 in the pumping unit beam 1 under the guiding connection of the traction seat 5. When the sliding seat 6 is located at the right side of the leading end of the frame telescopic body 2, the winding rope wound by the winch 9 can realize the right movement of the frame telescopic body 2 in the pumping unit beam 1 under the guiding connection of the traction seat 5. The two winches 9 are vertically divided and symmetrically arranged with respect to the frame telescopic body 2, and one end of the winding rope of the winch 9 is connected with the bearing 8 rotatably installed in the traction seat 5. The inner ring part of the bearing 8 is rotatably connected with the traction seat 5, and the outer ring side of the bearing 8 is connected with the winding rope. By using the independent rotation characteristics of the inner and outer rings of the bearing 8, after adjusting the position of the sliding seat 6, the outer ring part of the corresponding bearing 8 will rotate during the winding rope tensioning process, so as to ensure that the released winding rope is in a straight line state, and further ensure that the direction of the force is stable when pulling the traction seat 5 to move.

[0026] Two electric push rods 11 are symmetrically fixedly installed at the top edge of the sliding seat 6, the extension ends of the two electric push rods 11 are oppositely arranged and fixedly installed with the plug blocks 10 inserted into the top edge of the sliding seat 6.

When the frame telescopic body 2 is pulled by the winding rope wound by the winch 9, the winch 9 will generate a reaction force, which will cause the shearing force between the sliding seat 6 and the screw thread of the lead screw 7. In order to prevent the screw thread of the lead screw 7 from being stressed, when the sliding seat 6 moves to the both ends of the guide rail 17 so that the sliding seat 6 is located at the left side or the right side of the leading end of the frame telescopic body 2, the plug blocks 10 are inserted into the slot 16 at the end of the guide rail 17 by the extension of the electric push rods 11, so that the sliding seat 6 and the winch 9 can be fixed at the end of the guide rail 17 by the plug blocks 10, and the screw thread part of the lead screw 7 will not generate shearing force when the winch 9 is subjected to the reaction force.

[0027] In addition, the frame type telescopic body 2 is hollow, and a plurality of electric telescopic rods 13 are fixedly installed on the top surface of the hollow part of the frame type telescopic body 2, the telescopic ends of the plurality of electric telescopic rods 13 are fixedly installed with the inserts 14 penetratingly connected with the bottom of the frame type telescopic body 2, the slot bottom of the sliding slot 4 is fixedly installed with the hollow bottom plate 15 connected with the inserts 14, and when the frame type telescopic body 2 swings along with the up-down swing of the pumping unit beam 1, the inserts 14 are pushed into the hollow bottom plate 15 of the slot bottom of the sliding slot 4 through the electric telescopic rods 13, so that the relative position of the frame type telescopic body 2 and the pumping unit beam 1 is fixed, and the frame type telescopic body 2 is prevented from sliding in the sliding slot 4 when the pumping unit beam 1 swings up and down.

[0028] When the position of the frame type telescopic body 2 in the pumping unit beam 1 needs to be adjusted, for example, the frame type telescopic body 2 needs to move right in the pumping unit beam 1, the sliding seat 6 is moved to the right side of the first end of the frame type telescopic body 2, that is, to the right end position of the guide rail 17, by rotating the screw rod 7, the position of the sliding seat 6 is fixed by connecting the inserts 10 with the extension plates 12 and the notches 16 at the right position, then the frame type telescopic body 2 is driven to move right in the pumping unit beam 1 under the traction of the traction seat 5 by rotating and winding the center reel in the winch 9, and after moving to the specified position, the relative position of the frame type telescopic body 2 and the pumping unit beam 1 is fixed by pushing the inserts 14 into the hollow bottom plate 15 of the slot bottom of the sliding slot 4 through the electric telescopic rods 13.

[0029] The wiring diagram of the servo motor, the electric push rod 11 and the electric telescopic rod 13 in the utility model belongs to the common knowledge in the field, and the working principle is a known technology, and the type is selected according to actual use, so the control mode and wiring arrangement of the servo motor, the electric push rod 11 and the electric telescopic rod 13 are not explained in detail.
