Description

Technical Field

[0001] This utility model belongs to the field of oil pumping unit technology, specifically a refueling device used in the maintenance of oil pumping units. Background Technology

[0002] In the field of oilfield production, in order to ensure that the rotating parts on the pumping unit can operate with low frictional resistance and thus improve production efficiency, lubricating grease must be applied to several rotating parts when the pumping unit is first used, and the grease must be replaced regularly after use.

[0003] Meanwhile, application number CN202791254U, entitled "A Greaseer for Oil Pumping Unit Maintenance," describes a greaseer for oil pumping unit maintenance. It includes a housing fixed to a base plate, inside which is a four-bar rotating worktable. The tail end of a grease gun for oil pumping unit grease application is fixed to the four-bar rotating worktable, and a support frame is hinged to the middle of the grease gun. The bottom end of the support frame is positioned in a positioning groove on the four-bar rotating worktable. An oil storage tank for supplying grease to the grease gun is also fixed inside the housing. A pull rope is fixed to the top cover plate, and a rope hook that cooperates with the pull rope is fixed to the baffle plate. Using this greaseer, workers no longer need to hold it by hand; after adjusting the angle of the greaseer, only one worker needs to use a connecting hose to apply grease to the areas of the oil pumping unit requiring lubrication, thus reducing the worker's labor intensity and improving the efficiency of oil pumping unit grease application.

[0004] The above-mentioned technical solution requires manual operation during use, which involves manually pulling the baffle and rotating the four-bar linkage to push out the grease gun. This highly relies on manual operation, and operators need to repeatedly pull and rotate, which not only consumes a lot of physical strength but also makes the operation process cumbersome, resulting in low overall work efficiency.

[0005] Therefore, a lubricator for use in the maintenance of oil pumping units is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 6 As shown, this utility model provides a refueling device for oil pumping unit maintenance, including a work cart 1, an oil storage tank 12 installed in the work cart 1, and a grease gun 13 connected to the oil storage tank 12 via a delivery pipe.

[0028] The surface of the work cart 1 is equipped with an ejection opening and closing assembly 2. The ejection opening and closing assembly 2 includes a conical block 21 installed on the bottom surface of the grease gun 13, a door panel 22 symmetrically slidably connected to the opening of the work cart 1, and an inclined block 23, a moving bar 24, a connecting plate 25, a hydraulic rod 26, and a limiting block 27 for ejection opening and closing.

[0029] Two inclined blocks 23 are respectively installed on one side surface of the door panel 22. Two moving strips 24 are symmetrically installed on the surface of the conical block 21. The surface of the inclined block 23 is provided with a clearance groove that matches the moving strip 24. The moving strip 24 is slidably connected in this clearance groove. The connecting plate 25 is installed on one side surface of the conical block 21. The hydraulic rod 26 is installed inside the work cart 1. The telescopic end of the hydraulic rod 26 is connected to the connecting plate 25. Two limiting blocks 27 are symmetrically installed on the surface of the connecting plate 25. The surface of the work cart 1 is provided with a sliding groove that matches the limiting block 27. The limiting block 27 is slidably connected in this sliding groove. This allows the grease gun 13 to be easily pushed out of the work cart 1. During the pushing process, the door panel 22 is automatically opened, avoiding manual operation, reducing manual labor, simplifying the work process, and improving overall work efficiency.

[0030] The inclined block 23 is slidably connected in the through groove opened on the surface of the work vehicle 1, and one end of the inclined block 23 passes through the work vehicle 1 and extends to the outside of the work vehicle 1, and is connected to the limiting plate 28 set on the outside of the work vehicle 1, so as to limit the position of the inclined block 23 when it is retracted, and further improve the stability of the device.

[0031] A guide rod 29 is slidably connected in the through hole opened on the surface of the limiting block 27. Both ends of the guide rod 29 pass through the limiting block 27 and are installed in the slide groove opened on the surface of the work vehicle 1, so as to guide the movement of the limiting block 27 and prevent the limiting block 27 from falling off the position when moving.

[0032] The conical block 21 is adapted to the inclined surface of the inclined block 23, so that the inclined block 23 can be squeezed to both sides.

[0033] The surface of the work vehicle 1 is equipped with an automatic reset assembly 3. The automatic reset assembly 3 includes a slide bar 31 symmetrically installed on the surface of the door panel 22, a limit rod 32 slidably connected in a through hole on the surface of the slide bar 31, and a reset spring 33 for resetting.

[0034] The surface of the work cart 1 is provided with a limiting groove that matches the slide bar 31. The slide bar 31 is slidably connected in this limiting groove. Both ends of the limiting rod 32 pass through the slide bar 31 and are installed in the limiting groove on the surface of the work cart 1. The surface of the limiting rod 32 is symmetrically fitted with a return spring 33, so that the two door panels 22 can automatically close during the process of retracting the grease gun 13, further improving the working efficiency of the device and reducing the steps of manual operation.

[0035] One end of the return spring 33 is connected to the slide bar 31, and the other end of the return spring 33 is installed in the limiting groove opened on the surface of the work vehicle 1, so that the slide bar 31 can be easily reset, thereby pushing the door panel 22 to reset.

[0036] Among them, the structure of hydraulic rod 26 is existing technology and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent. Their working principle is already known technology, and the appropriate model is selected according to actual use.

[0037] The structure of the working cart 1, oil storage tank 12, and grease gun 13 in this device is the same as that of the published patent, application number CN202791254U, "A grease dispenser for oil pumping unit maintenance", and the working principle of the grease dispenser for oil pumping unit maintenance is the same.

[0038] Working principle and process: The operator first activates the hydraulic rod 26, whose telescopic end pushes the connecting plate 25 forward. The limiting block 27 slides along the slide groove to ensure that the conical block 21 moves in a straight line and avoids deviation. The guide rod 29 provides guidance for the limiting block 27 and enhances the stability of movement. When the conical block 21 moves forward, its inclined surface contacts the inclined surface of the inclined block 23, generating a lateral force. The inclined block 23 slides to both sides under the action of the force. At this time, the inclined block 23 slides in the through groove opened on the surface of the work cart 1, thereby driving the door panel 22 to open to both sides simultaneously. At this time, the door panel 22 slides inside the work cart 1. The moving bar 24 slides in the relief groove of the inclined block 23 to ensure smooth relative movement between the conical block 21 and the inclined block 23. At this time, the grease gun 13 is pushed out of the work cart 1 by the conical block 21 for easy access by the operator.

[0039] When the door panel 22 moves, the door panel 22 drives the slide bar 31 to slide in the limiting groove opened on the surface of the work vehicle 1. The limiting rod 32 limits the movement position of the slide bar 31 to ensure that the slide bar 31 moves in a straight line. During the linear movement, the slide bar 31 compresses the return spring 33, causing the return spring 33 to deform.

[0040] When retracting, the operator first controls the hydraulic rod 26 to retract, causing it to contract and pull the connecting plate 25 backward. The conical block 21 moves backward synchronously. After losing the thrust of the conical block 21, the return spring 33 releases its elastic potential energy, pushing the slide bar 31 to slide along the limiting groove, causing the door panel 22 to return to the center and close. The inclined block 23 moves synchronously with the door panel 22. When the inclined block 23 moves, the limiting plate 28 can limit the movement position of the inclined block 23. The door panel 22 is fully closed, the grease gun 13 returns to the initial storage position, and the hydraulic rod 26 returns to the contracted state, waiting for the next operation.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
