To sum up, among the oiling station that this application embodiment provided, moving structure can drive the fat liquoring structure and remove along beam-pumping unit hair pigtail to the fat liquoring structure can be at the in-process that removes along beam-pumping unit hair pigtail at beam-pumping unit hair pigtail surface fat liquoring. Therefore, the staff can move at ground control mobile structure to make the fat liquoring structure scribble the oil on beam-pumping unit hair pigtail surface, realize the maintenance to beam-pumping unit hair pigtail. Therefore, under the protection effect of oil, the hair braid of the oil pumping unit is not easy to wear and corrode, and the normal working probability of the oil pumping unit is improved.
And, the staff adopts the in-process of this oiling station maintenance beam-pumping unit hair pigtail, and the staff need not stand on the lift truck, consequently, can avoid the staff to fall from the lift truck.
The worker also does not need to coat the oil on the oil pumping machine hair braid by hand, thereby avoiding the situation that the hand is scratched by the oil pumping machine hair braid in the oil coating process of the worker.
In addition, the oiling station that this application embodiment provided removes better than the lift truck, and it is higher to use this oiling station to carry out the efficiency of maintenance to beam-pumping unit hair pigtail.
In the embodiment of the present application, the moving structure 101 and the oiling structure 102 in the oiling device 10 may be implemented in any one of a plurality of realizable manners as long as the moving structure 101 and the oiling structure 102 have the functions indicated in the embodiment of the present application.
The structure and function of the moving structure 101 and the oiling structure 102 will be further described below by taking an example of an implementation manner of the moving structure 101 and the oiling structure 102.
Before explaining the structures and functions of the moving structure 101 and the oiling structure 102, the structure of the pumping unit hair braid 03 is explained in the embodiment of the present application.
Illustratively, with continued reference to fig. 1, the pumping unit hair pigtail 03 comprises: two straight sections 031, and a bend section 032 connecting the two straight sections 031. It can be seen that one end of the pumping unit hair braid is connected with the polish rod 02, and the other end of the pumping unit hair braid winds the pumping unit horse head 01 to be bent, and then is also connected with the polish rod 02.
Fig. 3 is a schematic structural diagram of another oiling device provided in an embodiment of the present application, and as shown in fig. 3, on the basis of fig. 2, the moving structure includes: the tension spring 1011, and the barrel 1012, the support rod 1013, the fixed pulley 1014 and the pull rope 1015 corresponding to each straight section 031 in the oil pumping machine hair plait.
Therefore, the moving structure includes one tension spring 1011 and two sets of moving parts, wherein each set of moving parts includes: a barrel 1012, a strut 1013, a fixed pulley 1014, and a pull rope 1015. Two ends of the tension spring 1011 are respectively wound on the outer walls of the two cylinder portions 1012 corresponding to the two straight sections 031. Fat liquoring structure includes: and two oil coating parts 1021 corresponding to the two straight sections 031 in the oil pumping unit hair braid one by one.
For each straight section 031 of the pumping unit hair braid 03, and a set of moving parts (including the barrel 1012, the support rod 1013, the fixed pulley 1014 and the pull rope 1015) and the oil coating part 1021 corresponding to the straight section 031:
the oil coating portion 1021 is located on the first bottom surface M1 side of the cylindrical portion 1012, the cylindrical portion 1012 has magnetic force, and the cylindrical portion 1012 is adapted to be fitted around the straight portion 031.
The barrel portion 1012 may be made of a magnetic material as a whole, or may be made of a magnetic material in a partial region, which is not limited in the embodiment of the present application. The pumping unit hair braid 03 is generally made of steel and has a magnetic force with the barrel portion 1012.
The inner wall of the barrel portion 1012 includes: a straight wall region a1 and an inclined wall region a2, and an end of the inclined wall region a2 near the oiling section 1021 is inclined in a direction away from a central axis (not shown in the drawings) of the barrel section 1012; in the inner wall of the cylindrical portion 1012, the intersection of the straight wall region a1 and a cross section passing through the central axis of the cylindrical portion 1012 is parallel to the central axis, and the intersection of the sloped wall region a2 and the cross section forms an angle with the central axis. The minimum inner diameter of the cylindrical portion 1012 is larger than the maximum outer diameter of the straight section 031, so that the cylindrical portion 1012 can be moved back and forth on the corresponding straight section 031.
One end of the strut 1013 is fixed to the second bottom M2 of the tube 1012, and the other end is inclined in a direction away from the central axis of the tube 1012.
Fixed pulley 1014 is fixed to the other end of strut 1013.
One end of the pulling rope 1015 is fixed to the second bottom surface M2 of the tube portion 1012 corresponding to the other straight section 031 (for example, a pull ring is provided on the second bottom surface M2, and one end of the pulling rope 1015 is tied to the pull ring). The other end of the pull rope 1015 passes over the fixed pulley 1014.
The oil coating portion 1021 is connected with the cylinder portion 1012 and is used for moving along the straight section 031 under the driving of the cylinder portion 1012 and coating oil on the surface of the straight section 031.
The following will describe the process of the barrel 1012 moving over the straight section 031:
as shown in fig. 3, when the cylindrical portion 1012 is not moved, the cylindrical portion 1012 can be held still on the corresponding straight section 031 by the self-gravity, the magnetic force between the straight sections 031 corresponding to the cylindrical portion 1012, the frictional force between the straight sections 031, and the tensile force of the tension spring 1011.
When it is desired to control the barrel 1012 to move upward (closer to the buckle 032), the worker can alternately pull the other ends of the two pull cords 1015. As shown in fig. 4, the worker may pull the other end of one of the pull strings 1015 (the pull string on the right in fig. 4) and not pull the other end of the other pull string 1015 (the pull string on the left in fig. 4).
On the one hand, the strut 1013 to which the fixed pulley 1014 that the pulled right rope 1015 passes around is connected to exert a downward (away from the bending section 032) force on the connected drum 1012 (the right drum in fig. 4). At this time, the straight wall region a1 of the right cylindrical portion 1012 is kept in contact with the right straight section 031 corresponding to the right cylindrical portion 1012, and the right cylindrical portion 1012 is more closely fitted to the right straight section 031 as the downward force applied to the right cylindrical portion 1012 increases. Further, the right cylindrical portion 1012 is kept stationary in the right straight section 031 by the gravity of the right cylindrical portion 1012, the magnetic force with the right straight section 031, the frictional force with the right straight section 031, the force of the right rod 1013 corresponding to the right straight section 031, and the tensile force of the tension spring 1011.
On the other hand, the pulling rope 1015 on the right side applies a pulling force obliquely upward (obliquely toward the bent portion 032) to the other cylindrical portion 1012 (the cylindrical portion on the left side in fig. 4). At this time, one end of the straight wall region a1 of the left tubular portion 1012, which is distant from the bent portion 032, is inclined in a direction distant from the tubular portion 1012, and gradually separates from the straight portion 031 of the left tubular portion 1012. Further, since one end of the left cylindrical portion 1012 gradually separates from the left straight section 031, a large gap is formed between the left cylindrical portion 1012 and the left straight section 031, the frictional force between the left cylindrical portion 1012 and the left straight section 031 is reduced, and the left cylindrical portion 1012 can move upward (in a direction close to the bending section 032) by an external force. In the process of moving the left tubular portion 1012 upward, as shown in fig. 5, if the sloped wall area a2 of the left tubular portion 1012 contacts the left straight section 031, the friction force between the left tubular portion 1012 and the left straight section 031 increases, and the movement of the left tubular portion 1012 stops.
As shown in fig. 6, after the worker releases the other end of the pulled right rope 1015, the inclined wall area a2 of the left cylindrical portion 1012 gradually separates from the left straight section 031 under the action of the pulling force of the tension spring 1011, the self-gravity, and the magnetic force between the left straight section 031, and the straight wall area a1 of the left cylindrical portion 1012 abuts against the left straight section 031, thereby preventing the left cylindrical portion 1012 from falling.
As can be seen from fig. 3, 4, 5, and 6, the worker can move the left skirt 1012 upward by pulling the other end of the right pull rope 1015, and the right skirt 1012 remains stationary. Likewise, when the worker pulls the other end of the left pull rope 1015, the right skirt 1012 may move upward, and the left skirt 1012 remains stationary. Thus, the worker can pull the other ends of the two pulling ropes 1015 alternately to move the two cylinder portions 1012 upward alternately, thereby achieving the purpose that the whole moving structure moves on the oil pumping unit hair braid.
When it is desired to control the downward movement of the barrel 1012 (away from the buckle 032), the practitioner can pull the other end of both pull cords 1015 simultaneously. As shown in fig. 7, when the other ends of the two pulling ropes 1015 are pulled simultaneously, the straight wall regions a1 of the inner walls of the two cylindrical portions 1012 are separated from the pumping unit hair braid 03, and at this time, the two cylindrical portions 1012 move downward (in a direction away from the bending section 032) by their own weight and an external force.
Further, the cartridge portion 1012 can be implemented in a variety of ways, one of which will be described below.
Fig. 8 is a schematic structural diagram of another oiling device provided in an embodiment of the present application, and fig. 8 shows a sectional view of a structure sleeved on a straight section on the left side and a front view of the structure sleeved on a straight section on the right side. As shown in FIG. 8, the cartridge portion 1012 includes: a first component (comprising a first cartridge housing C1, a first magnetic cartridge C2, and a first tooth C3 arranged in order in a direction near the central axis of the barrel portion 1012) and a second component (comprising a second cartridge housing D1, a second magnetic cartridge D2, and a second tooth D3 arranged in order in a direction near the central axis of the barrel portion 1012).
The first component and the second component are located on either side of the central axis of the barrel portion 1012 and are connected by a first hinge (not shown in fig. 8) and a first catch K1. And, the first component and the second component both have magnetic force. The straight wall region a1 in the inner wall of the barrel portion 1012 includes the inner wall of the first component and the sloped wall region a2 in the inner wall of the barrel portion 1012 includes the inner wall of the second component. Thus, when the cylindrical portion 1012 needs to be fitted to the corresponding straight section 031, the first hook K1 can be opened, the first component and the second component can be fitted to the straight section 031, and finally, the first hook K1 can be closed.
For example, the first magnetic cartridge C2 may be embedded in the first cartridge case C1, and the first clamping tooth C3 may be fixed to the inner wall of the first cartridge case C1 by a first screw V1 passing through the first magnetic cartridge C2. The outer surface of the first cartridge case C1 may be provided with a groove for receiving the tension spring, and the first screw V1 may pass through the first cartridge case C1, the first magnetic cartridge C2, and the first jaw C3 in order from the groove.
The second magnetic holder D2 may be embedded in the second holder case D1, and the second clamping tooth D3 may be fixed to the inner wall of the second holder case D1 by a second screw V2 passing through the second magnetic holder D2. The outer surface of the second cartridge case D1 may be provided with a groove for receiving the tension spring, and the second screw V2 may sequentially pass through the second cartridge case D1, the second magnetic cartridge D2, and the second jaw D3 from the groove.
Note that, in order to ensure that the tension spring 1011 can be wound around the outer wall of the cylinder portion 1012 efficiently, the end portion of the tension spring 1011 is bent, and the outer wall of each cylinder portion 1012 may have a groove G in a region that contacts the tension spring 1011.
Optionally, the inner wall of the barrel portion 1012 has a latch (neither shown in the drawings), e.g., the surface of the first latch C3 distal from the first magnetic latch C2 has a latch and the surface of the second latch D3 distal from the second magnetic latch D2 has a latch. Under the action of the latch, the friction between the cylindrical portion 1012 and the corresponding straight section 031 is large.
The hardness of the first clamping tooth C3 and the second clamping tooth D3 is smaller than that of the oil pumping unit hair braid, so that the oil pumping unit hair braid cannot be damaged by the moving structure in the process that the moving structure moves along the oil pumping unit hair braid in the oil coating device provided by the embodiment of the application.
The above explains the moving structure in the oiling device, and the following explains the oiling structure in the oiling device. Referring to fig. 3, 4, 5, 6, 7, or 8, for the connected barrel portion 1012 and oiling portion 1021: the end of the barrel portion 1012 near the oil coated portion 1021 has a hook N1, the end of the oil coated portion 1021 near the barrel portion 1012 has a hanging ring N2, and the hanging ring N2 is hung on the hook N1, and it can be seen that the oil coated portion 1021 can be connected to the barrel portion 1012 by the hanging ring N2 and the hook N1.
Optionally, the oil coating portion 1021 is cylindrical and is used for being sleeved outside the corresponding straight section 031; the oil coating portion 1021 has an oil storage chamber X in the cylinder wall, an oil filling port (not shown in fig. 8) is provided at an end of the oil storage chamber X close to the cylinder portion 1012 to which the oil coating portion 1021 is connected, and an oil outlet (not shown in fig. 8) is provided at an end of the oil storage chamber X far from the cylinder portion 1012 to which the oil coating portion 1021 is connected. Optionally, the end of the oil outlet of the oil storage chamber X is pointed.
When the oil coating portion 1021 moves upwards (in a direction close to the bending section) under the driving of the moving structure, oil in the oil storage cavity X of the oil coating portion 1021 flows out from the oil outlet and adheres to the oil pumping unit hair braid 03. And because the end that the oil-out of oil storage chamber X is located is sharp, consequently, the oil that flows out from oil storage chamber X is less for oil can thin and scribble uniformly on the surface of beam-pumping unit hair pigtail, plays the effect of maintaining beam-pumping unit hair pigtail promptly, has avoided oil to scribble again thickly and has melted when ambient temperature is higher and drip, and has reduced the oil consumption.
Alternatively, like the barrel portion 1012, the oiling portion 1021 includes: a third component and a fourth component; the third component and the fourth component are respectively located on both sides of a central shaft (not shown in the drawing) of the oiling section 1021, are connected by a second hinge (not shown in fig. 8) and a second buckle K2 (two second buckles K2 are taken as an example in fig. 8), and each have an oil storage chamber X. Thus, when the oil coating portion 1021 needs to be sleeved on the corresponding straight section 031, the second buckle K2 can be opened, the third component and the fourth component can be sleeved on the straight section 031, and finally, the second buckle K2 can be closed.
When adopting the oiling station that this application embodiment provided to beam-pumping unit hair pigtail to maintain, the staff can at first break off the power supply brake with the beam-pumping unit, then all cup joint two section of thick bamboo portions in the removal structure on beam-pumping unit hair pigtail to and will crowd two fat liquoring portions of full oil and also cup joint on beam-pumping unit hair pigtail, and hang two fat liquoring portions respectively on two section of thick bamboo portions.
Afterwards, the staff can grasp two stay cords respectively by the left hand and the right hand, and pull the stay cords left and right alternately to make two sections of thick bamboo drive two fat liquoring portions alternately and upwards to move, and at this in-process, two fat liquoring portions can fat liquoring at the surface of beam-pumping unit hair pigtail.
After the oiling is finished, the worker can pull the two pull ropes downwards at the same time so that the two cylinder parts and the two oiling parts slide down along the oil pumping unit hair braid, and then the whole oiling device is stopped from the oil pumping unit hair braid.
The oiling station that this application embodiment provided is applicable to the maintenance of various model beam-pumping unit hair pigtail, and the staff can maintain the beam-pumping unit hair pigtail of eminence on ground, and need not the lift truck cooperation. Because the cost of lift truck is higher, and this application embodiment need not to adopt the lift truck to maintain beam-pumping unit hair pigtail, consequently reduced the maintenance cost to beam-pumping unit hair pigtail. The oiling station that this application embodiment provided's use risk is lower, and only needs a staff can accomplish the maintenance work to beam-pumping unit hair pigtail, has reduced the required number of maintenance beam-pumping unit hair pigtail.
