Abstract
The utility model discloses a pneumatic percussive crankpin detaching device for oil pumping units used for oil production, which is mainly formed by connecting an adjusting mechanism with an air compressor via a gas outlet pile with a control valve arranged in the middle, wherein a rotating handgrip is designed in the middle of the adjusting mechanism, one end of the adjusting mechanism is connected with a backstop element, the other end of the adjusting mechanism is connected with a percussive hammer designed with a cylinder, and a percussive hammer head is arranged in the cylinder. The pneumatic percussive crankpin detaching device for oil pumping units used for oil production has a simple structure, convenient usage, can safely take out the crank fixing pin of an oil pumping unit, and reduce labor work and potential safety hazards.
Description
Affiliated technical field:
The utility model relates to a kind of crank steady pin withdrawing device of oil pumper equipment of oil extraction use, particularly a kind of Pneumatic impact crank steady pin withdrawing device, when being suitable for displacement of oil pumper equipment or maintenance, the operation that the crank steady pin can take out easily.
Background technology:
At present, technique known is, the taking-up of oil pumping machine crank steady pin is to be got from the bottom up with sledgehammer by the workman, effort, dangerous, careless slightly, and casualty accident constantly takes place, and is hard nut to crack that not have solution for many years in the oil recovery workover treatment.
Summary of the invention:
For the deficiency of the taking-up technology that overcomes existing oil pumping machine crank steady pin, the utility model provides the provision for disengagement of a kind of Pneumatic impact crank-pin, and this device is used for the dismounting of oil pumper equipment crank steady pin, operation that can be easily.
The technical scheme that its technical problem that solves the utility model adopts is: design has the governor motion of turning handle in the middle of making one; the one end is connected with retaining spare; the other end has the impact hammer of cylinder to be connected with design; install in the cylinder and impact tup; and with the screw thread protective sleeve, set upright the tube be connected, have the appendix of control valve to be connected by middle design and installation and constitute with air compressor machine.During use, the screw thread protector with being threaded on the crank-pin screw thread, is without prejudice to protect this screw thread, subsequently this device is placed between left crank and the right crank, and face left and right two crank-pins.Turning handle makes this device hold out against left and right two cranks, starts air compressor machine, and its pressure is raise, when pressure was elevated to certain numerical value, opening controlling valve made tup impact crank-pin and takes out up to crank-pin to gas storage storehouse air feed, with the tune of this device, repeat aforesaid operations then, right crank-pin is taken out.Promptly finish whole operations.
The beneficial effects of the utility model are: can trip out the crank steady pin of oil pumper safely, reduce labor operation and hidden danger factor.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Accompanying drawing number is: 1, former left crank, 2, former crank-pin, 3, the screw thread protective sleeve, 4, set upright tube, 5, impact tup; 6, impact hammer, 7, governor motion, 8, turning handle, 9, retaining spare; 10, former right crank, 11, air compressor machine, 12, control valve, 13, appendix.
The specific embodiment:
Referring to Fig. 1; make design in the middle of being connected with a muzzle and the governor motion (7) that constitutes by screw rod of turning handle (8) arranged; the one end is connected with retaining spare (9); the other end has the impact hammer (6) of cylinder to be connected with design; install in the cylinder and impact tup (5); and with screw thread protective sleeve (3), set upright the tube (4) be connected, have the appendix (13) of control valve (12) to be connected by middle design and installation and constitute with air compressor machine (11).During use; screw thread protective sleeve (3) with being threaded on former crank-pin (2) screw thread, is without prejudice to protect this screw thread, subsequently this device is placed between former left crank (1) and the former right crank (10); tube (4) is set upright in adjustment, makes impact tup (5) face left and right two former crank-pins.Rotate turning handle, make this device hold out against left and right two cranks, start air compressor machine (11), its pressure is raise, and when pressure was elevated to certain numerical value, opening controlling valve (12) was to the air reservoir air feed, making impact tup (5) impact former left crank-pin takes out up to crank-pin, with the tune of this device, repeat aforesaid operations then, former right crank-pin is taken out.Promptly finish whole operations.
Claims (2)
1, a kind of Pneumatic impact crank-pin provision for disengagement, it is characterized in that: design has the governor motion of turning handle in the middle of making one, the one end is connected with retaining spare, the other end has the impact hammer of cylinder to be connected with design, install in the cylinder and impact tup, have the appendix of control valve to be connected by middle design and installation and constitute with air compressor machine.
2, Pneumatic impact crank-pin according to claim 1 provision for disengagement is characterized in that: tube and screw thread protective sleeve are set upright in the impact hammer end design of governor motion.
