The utility model relates to a self-adjusting buffer type suspender for a pumping unit, which is composed of a shell, a buffer spring and a pressure cover. The lower part of the shell is provided with an annular buffer bin, the buffer bin is provided with a buffer spring, the top of the buffer bin is provided with a hollow compression plunger, one end of the buffer spring is fixed in the buffer bin, and the other is fixed in the buffer bin. One end is fixed at the bottom of the hollow compression plunger. The hollow compression plunger has a universal sphere in its inner seat. The hollow sphere, the hollow compression plunger and the buffer bin are longitudinally penetrated through the holes of the bare rod. The side wall of the shell is provided with a suspension rope fixed wing, the suspension rope fixed wing is provided with a longitudinal penetrating suspension rope fixed gap, and the side wall of the suspension rope fixed gap is provided with a suspe The top and bottom of the shell are respectively provided with a gland and a threaded joint. The utility model has the functions of double shock absorption, strong buffering load capacity, rotating and untwisting of the lifting rope, connecting the fishing drum, etc., and solves the rod breakage phenomenon under the conditions of alignment, scissors difference, load, etc., and greatly improves the service life of the bare rod of the pumping unit.

抽油机自调整体缓冲式悬绳器
本技术涉及一种抽油机悬绳器,尤其涉及一种抽油机自调整体缓冲式悬绳器。
技术介绍
悬绳器是连接光杆和驴头的柔性连接件,通过驴头弧面和悬绳器可保证光杆沿油管中心作往复运动,它是驴头与光杆柔性连接重要装置,井下载荷变化使吊绳打钮,由于对中、剪刀差、载荷等问题的出现及变化,还会出现断杆现象,存在一定的安全隐患,影响产量浪费成本。
技术实现思路
本技术对于上述现有技术的不足,提供了一种抽油机自调整体缓冲式悬绳器。本技术的抽油机自调整体缓冲式悬绳器,是由壳体、缓冲弹簧和压盖构成,所述的壳体内的下部设有环形缓冲仓,缓冲仓内设有缓冲弹簧,缓冲仓的顶部设有空心压缩柱塞,缓冲弹簧的一端固定于缓冲仓内、另一端固定于空心压缩柱塞的底部,空心压缩柱塞内座有万向球体,万向球体、空心压缩柱塞和缓冲仓的内部纵向贯穿了光杆孔,壳体的侧壁设有吊绳固定翼,吊绳固定翼上设有纵向贯穿的吊绳固定豁口,吊绳固定豁口的侧壁上设有吊绳固定销,所述的壳体的顶部设有压盖、其底部设有丝扣连接头。作为本技术的进一步改进,所述的壳体的侧壁设有两个吊绳固定翼,两个吊绳固定翼相对而置。本技术的抽油机自调 ...
