The polished rod suspension system of the pumping unit comprises a rope hanger 100, the rope hanger 100 is the prior art, and will not be described in detail in this embodiment, the lower ends of two sections of lifting ropes 500 respectively penetrate through the lower ends of the rope hanger 100 and are fixed through rope clamps, the rope clamps are pressed against the lower ends of the rope hanger 100, and the lifting ropes 500 bear various loads during oil pumping through the rope hanger 100. The polish rod 600 passes up and down through the polished rod eye 100. The dimension of the rope hanger 100 in the direction of the spaced arrangement of the two suspension ropes 500 is larger than the dimension perpendicular to the direction.
Supporting device 200 has been placed in the upper end of polished rod eye 100, and supporting device 200 does the utility model discloses a core content, supporting device 200 include that the back-off supports the U-shaped support 21 on polished rod eye 100, and two support arms 212 of U-shaped support 21 distribute side by side along the interval orientation of arranging of two lifting ropes 500, and the central through-hole 211 that runs through from top to bottom is seted up in the centre department of U-shaped support 21, and central through-hole 211 supplies polished rod 600 to pass.
The two sides of the U-shaped bracket 21 are respectively fixed with a semi-ring structure, the semi-ring structure in this embodiment comprises two ear plates 22, the interval arrangement direction of the two ear plates 22 is perpendicular to the interval arrangement direction of the two support arms 212, the interval arrangement between the two ear plates 22 forms an opening facing the lifting rope 500, the ear plates 22 are provided with through holes 23, the two through holes 23 of the two corresponding ear plates 22 are correspondingly communicated, when in use, the pin penetrates through the two through holes 23 simultaneously, and the lifting rope 500 is completely sleeved in the semi-ring structure.
In this embodiment, the pin forms a stop rod capable of stopping the lifting rope 500 from coming off, and in other embodiments, other rod members may be used as the stop rod. The half-ring structure includes two otic placodes and a pin, when including with lifting rope 500 suit, can insert to lifting rope 500's outside along lifting rope 500's radial direction, and it is comparatively convenient to install. In other embodiments, the half-ring structure may be a unitary structure, such as a C-ring, but may be installed with one end of the lifting line 500 threaded therethrough. In this embodiment, the half-ring structure and the corresponding side of the U-shaped bracket 21 are used to form the fixing ring together, and in other embodiments, the fixing ring may be a closed ring structure independent of the U-shaped bracket 21 and installed on the U-shaped bracket 21 by welding or the like.
As shown in fig. 1, a load clip 400 is supported and placed above the supporting device 200, an anti-slip clip 300 is accommodated in the supporting device 200, and both the load clip 400 and the anti-slip clip 300 are clamped on a polish rod 600. In fact, either the anti-slip clip 300 or the load clip 400 includes two half-ring bodies having an anchor therein, and the two half-ring bodies are assembled together by bolts when assembled, and the anchor bites the polish rod 600. In this embodiment, the anti-slip clip 300 is spaced from the rope hanger 100 and the U-shaped bracket 21, and the anti-slip clip 300 does not receive the upward force in the vertical direction during normal use.
The utility model discloses a use as follows: as shown in fig. 1, in a normal oil pumping state, the supporting device 200 is pressed against the polished rod eye 100, the load clamp 400 clamps the polished rod 600 and presses against the supporting device 200, the anti-slip clamp 300 is not pressed in the vertical direction, the polished rod passes through the load clamp 400, the anti-slip clamp 300 and the supporting device 200, and the lifting rope 500 passes through the supporting device 200. When the oil pumping is normal, even if the oil pumping rod and the polish rod 600 rotate, the polish rod 600 drives the load clip 400 and the anti-drop clip 300 to rotate, even if the load clip 400 is pressed against the supporting device 200, because the two ends of the supporting device 200 are stopped and limited by the corresponding lifting ropes 500, the supporting device 200 cannot rotate along with the load clip 400, and the support arm 212 in the supporting device 200 cannot be separated from the supporting device 200 due to the overlarge rotation amplitude, so that the supporting device 200 is pressed against the anti-drop clip 300.
When the polished rod part corresponding to the load clamp 400 is broken, the polished rod 600 moves downwards under the self-weight and drives the anti-drop clamp 300 to be pressed on the rope hanger 100, so that the polished rod 600 is prevented from dropping into the well.
In this embodiment, the fixing rings are disposed on two sides of the upper end of the U-shaped bracket 21, so that the rotation amplitude of the U-shaped bracket 21 driven by the load clip 400 can be further reduced.
The utility model discloses beam-pumping unit polished rod is strutting arrangement's for suspension's concrete embodiment, strutting arrangement are unanimous with the strutting arrangement in above-mentioned each embodiment, and its content is no longer repeated.
