Abstract
The utility model relates to a beam-pumping unit, in particular to an anti-theft pressure bar device for the beam-pumping unit. A pressure bar bolt of the device penetrates through a pressure bar and a shell, and a lug boss at the lower end of the shell is inserted into a pressure bar groove so that the shell and the pressure bar can not rotate around a central line of the pressure bar bolt; the anti-theft shell is tightly pressed on the pressure bar by a pressure bar nut when the pressure bar nut and the pressure bar bolt are connected, and three stepped holes are formed in the lower end of an inner hole of an inner plug and are respectively provided with an upper anti-theft sleeve, a lower anti-theft sleeve and a pressure pad from top to bottom; the stepped hole with the lower anti-theft sleeve is eccentric to the axis of the inner plug, and the inner plug is in threaded connection with the inner hole of the anti-theft shell; the pressure pad is pressed on the pressure bar nut, and the inner hole of the inner plug is in clearance fit with the upper and lower anti-theft sleeves; an anti-theft spanner is of an eccentric structure, and a handle of the anti-theft spanner can slide left and right in a hole of the upper end of the anti-theft spanner. The anti-theft pressure bar device realizes the effect that the pressure bar of the beam-pumping unit is prevented from being stolen, and the defect that the existing pressure bar of the beam-pumping unit is frequently stolen is overcome.
Description
Technical field:
The utility model relates to a kind of beam pumping unit, particularly a kind of beam pumping unit antitheft pressure lever device.
Background technology:
The beam pumping unit generally using in oilfield development process need to be arranged on oil pumping unit base with pressure thick stick, often occurs the stolen problem of oil pumper pressure thick stick in oil pumper running.After oil pumper presses thick stick stolen, oil pumper can topple, and the lighter can cause mechanical accident, and severe one can cause human casualty accident.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of beam pumping unit antitheft pressure lever device, and this device has been realized and prevented that oil pumper pressure thick stick is stolen.Overcome existing oil pumper and pressed often stolen deficiency of thick stick.
Technical solution adopted in the utility model is: a kind of beam pumping unit antitheft pressure lever device, by Anti-theft wrench handle, Anti-theft wrench, interior stifled, upper stealingproof sleeve, lower stealingproof sleeve, pressure pad, anti-theft outer casing, pressure thick stick nut, press thick stick and press thick stick bolt to form, press thick stick bolt through pressing thick stick and shell, shell lower end has a boss to be bumped into press makes shell and press can not be around pressing thick stick bolt center line rotate between thick stick in thick stick groove, press thick stick nut to be connected and to press thick stick nut that anti-theft outer casing is pressed on thick stick simultaneously with pressure thick stick bolt, there are three stepped holes interior stifled endoporus lower end, three stepped holes are installed respectively stealingproof sleeve from top to bottom, lower stealingproof sleeve and pressure pad, stepped hole and the interior stifled eccentric axis of lower stealingproof sleeve are installed, interior blocking up is connected by screw thread with anti-theft outer casing endoporus, pressure pad is pressed on thick stick nut, interior stifled endoporus and upper stealingproof sleeve and lower stealingproof sleeve are matched in clearance, Anti-theft wrench is eccentric structure, Anti-theft wrench handle can horizontally slip in Anti-theft wrench upper end hole.
The beneficial effects of the utility model are: the utility model can prevent that oil pumper pressure thick stick is stolen, prevents to press the stolen security incident causing of thick stick because of oil pumper.
Brief description of the drawings:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of beam pumping unit antitheft pressure lever device, by Anti-theft wrench handle 1, Anti-theft wrench 2, interior stifled 3, upper stealingproof sleeve 4, lower stealingproof sleeve 5, pressure pad 6, anti-theft outer casing 7, press thick stick nut 8, press thick stick 9 and press thick stick bolt 10 to form, press thick stick bolt 10 through pressing thick stick 9 and shell 7, shell 7 lower ends have a boss to be bumped into press makes shell 7 and press can not be around pressing thick stick bolt 10 center lines rotate between thick stick 9 in thick stick 9 grooves, press thick stick nut 8 to be connected and to press thick stick nut 8 that anti-theft outer casing 7 is pressed on thick stick 9 simultaneously with pressure thick stick bolt 10, there are three stepped holes interior stifled 3 endoporus lower ends, three stepped holes are installed respectively stealingproof sleeve 4 from top to bottom, lower stealingproof sleeve 5 and pressure pad 6, stepped hole and interior stifled 3 eccentric axis of lower stealingproof sleeve 5 are installed, interior stifled 3 are connected by screw thread with anti-theft outer casing 7 endoporus, pressure pad 6 is pressed on thick stick nut 8, interior stifled 3 endoporus and upper stealingproof sleeve 4 and lower stealingproof sleeve 5 are matched in clearance, Anti-theft wrench 2 is eccentric structure, Anti-theft wrench handle 1 can horizontally slip in Anti-theft wrench 2 upper end holes.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
