Fig. 1 shows a polished rod centering protection device 100 according to the present invention. As shown in fig. 1, the polish rod centering protection device 100 includes a base 10 disposed on the ground. The base 10 is configured as a flat plate that is disposed on the ground on the side of the polished rod 12 remote from the pumping unit 15. A bracket 20 is fixed to the base 10. The holder 20 is configured as a boss having a certain height. Wherein the bracket 20 is preferably arranged at the geometric center of the base 10. Meanwhile, a pin mounting hole 25 is also formed in the bracket.
As shown in fig. 1, the polish rod centering protection device 100 further includes a connecting assembly 11 disposed on the base 10, wherein the connecting assembly 11 includes a first connecting rod 30. The first link 30 is a circular tube, which is leaned against the bracket 20. A through hole 35 is provided on an outer wall of the first link 30. The bracket 20 and the first link 30 are connected by a pin 28, and the pin 28 is disposed in the pin mounting hole 25 and penetrates the through hole 35. Thereby, the first link 30 and the bracket 20 can be fixedly connected together by the pin 28.
In a preferred embodiment, a plurality of through holes 35 are uniformly provided in the outer wall of the first link 30 in the axial direction. It will be readily appreciated that the operator can control the angle of inclination of the first link 30 by inserting the pins 28 into the various through holes 35.
Meanwhile, a support rod 18 is further disposed on the base 10, and the support rod 18 is disposed at an end of the bracket far from the first link 20. The support rod 18 abuts against the rod body of the first link 20 for assisting in supporting the first link 20. Preferably, the support bar 18 is hinged to the base 10, being rotatable about the plane of the base 10. Thus, when the inclination angle of the first link 30 changes, the support bar 18 can be rotated correspondingly to find the most appropriate support angle of the support bar 18, thereby ensuring that the support bar 18 has the best support effect all the time.
As shown in fig. 1, the connecting assembly 11 includes a second link 40. The second link 40 is connected to the upper end 32 of the first link 30, i.e. the end remote from the base 10. Necessarily, the diameter of the second link 40 is set to be smaller than the diameter of the first link 30. Thereby, the second link 40 is allowed to be inserted into the first link 30 while being freely movable in the axial direction within the first link 30. Thus, by controlling the movement of the first link 30, the overall length of the first link 30 and the second link 40 can be adjusted. Meanwhile, a jack screw locking hole 34 is further formed in an outer wall of the upper end 32 of the first link 30. Thus, the first link 30 and the second link 40 can be fixed together by the jackscrew, thereby limiting the relative movement between the two and fixing the overall length of the two. It should be noted that the first link 30 and the second link 40 may also be fixed together by other means, and the fixing manner or the connection manner between the two is not limited herein.
It is easy to understand that when the worker adjusts the position of the bottom plate 10 according to the actual working condition, the second connecting rod 40 can be ensured to be always abutted against the horse head of the pumping unit by adjusting the angle of the first connecting rod 30 and the overall length of the first connecting rod 30 and the second connecting rod 40.
In addition, a pressing plate 50 is disposed at an upper end of the second link 40, i.e., an end far from the base 10. The pressing plate 50 is a flat plate having a certain thickness and is fixedly coupled to the upper end of the second link 40. The pressing plate 50 is used for pressing the polished rod 12 on the horse head of the pumping unit 15.
In a preferred embodiment, a groove (not shown) is provided on the face of the pressure plate 50 adjacent to the polish rod 12, the groove is configured as a semicircle adapted to the polish rod 12, and the contact surface of the groove against the sucker rod is configured as an arc surface, so that the groove helps to ensure that the pressure plate 50 can tightly press the polish rod 12 against the horse head of the pumping unit 15.
In the present invention, the diameter of the first link 30 may be set to 3.6-4.0cm, and the diameter of the second link 40 may be set to 2.4-3.0 cm. Practical operation shows that the first connecting rod 30 and the second connecting rod 40 in the diameter range have good connection strength and good crimping effect.
Meanwhile, in order to prevent the base 10 from moving under the action of external force and affecting the righting effect, at least one pin shaft mounting hole 16 is further formed in the wall bodies at the two ends of the base 10. This allows a fastening pin (not shown) to be driven into the pin mounting hole 16, and the base 10 is fixed to the ground by the fastening pin.
The following briefly describes the use of the polished rod centering protection device 100 according to the present invention.
When the polished rod is lifted by a crane and needs to be centered, the overall length of the first connecting rod 30 and the second connecting rod 40 is adjusted, the first connecting rod 30 and the second connecting rod 40 lean against the horse head of the pumping unit 15, and the polished rod 12 is ensured to be positioned in the groove on the pressing plate 50. Secondly, the second link 40 is fixed by a jackscrew, preventing the second link 40 from continuing to move within the first link 30. Then the pin 28 is used to connect the first link 30 to the bracket 20 of the base 10, and simultaneously the support bar 18 is rotated, so that the support bar 18 abuts against the second link 40, thereby ensuring the supporting effect of the second link 40. Finally, a fastening pin is driven into the pin shaft mounting hole 16, and the base 10 is fixed to the ground.
After the base 10 is fixed, the polished rod centering protection device 100 can perform a centering function on the polished rod, the crane can be driven away at the moment, the service time of the crane is shortened, the cost of the crane is saved, meanwhile, the phenomenon that workers climb to the mule head of the oil pumping unit is avoided, and the safety is improved.
