The connecting rod detacher for the pumping unit provided by the embodiment of the disclosure adopts the matching of the jack 3 and the pull claw 2, so that the connecting rod is easy to mount when detached, the stress of the connecting rod pull ring 102 is uniform, the detaching speed is high, the labor intensity of workers is reduced, and the detaching device is safe and reliable.
Illustratively, the main body 1 comprises a central block 11 and at least two connecting arms 12, the connecting arms 12 corresponding one-to-one to the pull claws 2, a first end of the connecting arm 12 being connected to an outer edge of the central block 11 and a second end of the connecting arm 12 being connected to the pull claw 2.
In the above implementation, arranging the main body 1 as the central block 11 and the connecting arm 12 enables the abutment between the end surface of the central block 11 and the jack 3, i.e. the central block 11 provides an abutment force for one end of the jack 3, so that the base of the jack 3 can press the end surface of the crank pin 101. The connecting arm 12 is arranged to facilitate the movable connection with the pull claw 2.
Illustratively, the side of the center block 11 facing the jack 3 has an inner groove 111, and the jack 3 is located in the inner groove 111.
In the above implementation manner, the inner groove 111 is configured to accommodate the jack 3 and the crank pin 101, so that the bottom surface of the inner groove 111 can provide a supporting acting force for the jack 3, and it is ensured that the base of the jack 3 can extrude the end surface of the crank pin 101.

In the above implementation, by providing the pulling claw 2 as the first arm 21, the intermediate arm 22, and the second arm 23, the connection with the main body 1 can be achieved through the first arm 21.
The intermediate arm 22 serves to connect the first arm 21 with the second arm 23, the second arm 23 being intended to abut against one side of the connecting rod tab 102 in order to catch the connecting rod tab 102 in preparation for the subsequent separation of the connecting rod tab 102 from the crank pin 101.
In order to facilitate the quick connection between the connecting arm 12 and the first arm 21, the connecting arm 12 has a connecting slide 123 inside, and the first arm 21 is movably inserted into the connecting slide 123.
Continuing with FIG. 1, the first arm 21 has graduations 211 on the outer wall thereof, the graduations 211 extending axially along the first arm 21.
In the above implementation, the graduation mark 211 is used to adjust the length of the first arm 21 inserted in the connecting arm 12. That is, by observing the scale marks 211 on the first arm 21, the relative distance between the second arms 23 can be adjusted to fit the diameter of the crank pins of different pumping units.
When in use, the innermost distance between the second support arms 23 of the pulling claw 2 is generally smaller than the outer diameter of a connecting rod pull ring of a corresponding pumping unit type by 10 mm, so that the pulling claw 2 can hook the connecting rod pull ring firmly.
Illustratively, the second end of the second arm 23 has a slope 231, and the slope 231 is inclined toward the main body 1 in a direction from the first end to the second end of the second arm 23.
In the above implementation, the inclined surface 231 is used to increase the contact area between the second arm 23 and the link tab 102. And the second arm 23 is prevented from being too long to affect the use.
Illustratively, the side of the second arm 23 facing the main body 1 has a clamping pad 232.
In the above implementation, the clamp pad 232 is used to prevent the link tab 102 from being worn or damaged when the second arm 23 abuts on the link tab 102.
Illustratively, the main body 1 and the pull claw 2 are both integrally formed structural members.
In the implementation mode, the main body 1 and the pull claw 2 are arranged to be integrally formed structural members, so that the machining and manufacturing efficiency of the oil pumping unit connecting rod detacher can be improved.
The jack 3 is exemplarily a scissor jack.
In the above implementation, the scissor jack can more conveniently brace between the crank pin 101 and the main body 1, so that the crank pin 101 can be quickly separated from the connecting rod pull ring 102.
Illustratively, the oil pumping unit connecting rod detacher further comprises a jackscrew 5, wherein a first end of the jackscrew 5 is inserted into the main body 1, and a second end of the jackscrew 5 abuts against the outer wall of the first support arm 21.
In the above implementation manner, the connecting arm 12 and the first arm 21 can be connected together by the jackscrew 5, and the length of the first arm 21 inserted in the connecting arm 12 can be realized by adjusting different positions of the jackscrew 5 on the connecting arm 12, so that the second arm 23 can be adjusted to hook the connecting rod pull rings 102 with different diameters.
The working mode of the oil pumping unit connecting rod detacher provided by the embodiment of the disclosure is briefly introduced as follows:
firstly, the position of the pull claw 2 on the connecting arm 12 is adjusted, namely, by observing different scale marks 211 on a first support arm 21 in the pull claw 2, each scale mark 211 corresponds to the diameter size of a crank pin of an oil pumping unit type, so that the innermost distance between the two pull claws 2 is smaller than the outer diameter of a connecting rod pull ring of the corresponding oil pumping unit type by 10 mm, and then, the jackscrew 5 is screwed down, so that the first support arm 21 is fixed on the connecting arm 12.
The detacher is then inserted over the pump link and crank pin so that the pull claw 2 is behind the link pull ring 102 and the pump link detacher is suspended from the end faces of the link pull ring 102 and crank pin 101.
And finally, adjusting a screw rod on the jack 3 by using an electric wrench, so that the base of the jack 3 is in contact with the end face of the crank pin 101 to bear force, continuously adjusting the screw rod, and driving the pull claw 2 by the jack 3 to separate the connecting rod pull ring 102 with the fixed bolt detached from the crank pin 101, thereby completing the detachment of the connecting rod.
The above description is meant to be illustrative of the principles of the present disclosure and not to be taken in a limiting sense, and any modifications, equivalents, improvements and the like that are within the spirit and scope of the present disclosure are intended to be included therein.
