Abstract
The utility model relates to a tensioner for disassembling a jib of a pumping unit. The tensioner for disassembling the jib of the pumping unit is characterized in that the tensioner is provided with a pair of bridge plates (1), supporting legs (2) are arranged at the lower ends of the bridge plates (1), screw holes (3) are formed in the upper parts of the bridge plates (1), screws (4) are installed in the screw holes (3) in a penetrating way, threads (5) are arranged on the screws (4), washers (6) and nuts (7) are respectively arranged at the two ends of the screws (4), a supporting bar (8) which is matched with the bridge plates (1) is arranged and the supporting bar (8) is arranged between the two bridges (1); arc surfaces (9) are oppositely arranged on the inner sides of the bridge plates (1). The tensioner for disassembling the jib of the pumping unit has the advantages that the tensioner is convenient and practical and is a favorable tool for disassembling the jib of the pumping unit, the time and the labor are saved and the working efficiency is greatly improved.
Description
Technical field
The utility model belongs to mechanical equipment technical field, is a kind of for dismantling oil-field oil pumper arm force expander specifically.
Background technology
Mostly the arm of pumping unit for oil field is to press together with suspension rod suit, due between coordinate closely, during repair demolition, bring larger difficulty.In the past, during dismounting, be all chock beyond the Great Wall between two, with iron hammer, firmly impact chock, under the tension of chock, by two parts separately, this way often just can be taken an oil pumper apart with the time of half a day to one day.Time-consuming, effort, labour intensity is large, and efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, time saving and energy saving dismounting oil pumper arm force expander.Realizing technical solution adopted in the utility model is: this force expander is provided with a pair of bridge plate, the lower end of bridge plate is provided with feet, the top of bridge plate has screw hole, installs screw rod in screw hole, and screw rod is provided with screw thread, the two ends of screw rod arrange respectively packing ring and nut, be equipped with support stick with bridge plate, support stick is arranged between two bridge plates, and the inner side of described bridge plate is provided with cambered surface relatively, be convenient to support stick firm between bridge plate, be difficult for sliding.During use, first the feet of the lower end of a pair of bridge plate of this force expander is placed between oil pumper arm and fuselage, with spanner fastening nut simultaneously inwardly, under leverage, oil pumper arm is unloaded on by suspension rod.
The utility model is convenient and practical, is the tool of dismounting oil-field oil pumper arm, the time saving and energy saving operating efficiency that greatly improved.This force expander also can be used for other object that need to open.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
In figure: 1, bridge plate, 2, feet, 3, screw hole, 4, screw rod, 5, screw thread, 6, packing ring, 7, nut, 8, support stick, 9, cambered surface.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.A kind of dismounting oil pumper arm force expander, this force expander is provided with a pair of bridge plate 1, and the lower end of bridge plate 1 is provided with feet 2, and the top of bridge plate 1 has screw hole 3, in screw hole 3, install screw rod 4, screw rod 4 is provided with screw thread 5, and the two ends of screw rod 4 arrange respectively packing ring 6 and nut 7, is equipped with support stick 8 with bridge plate 1, support stick 8 is arranged between two bridge plates 1, the inner side of described bridge plate 1 is provided with cambered surface 9 relatively, is convenient to support stick firm between bridge plate, is difficult for sliding.
