[0032] Combination Figures 1 to 6 As shown, the intelligent centralized lubrication system for a workover rig provided by the utility model comprises a first progressive distributor 11, a second progressive distributor 12 and a lubrication pump.

[0033] Combination Figures 1 to 6 As shown, the lubrication points on the well repair rig are divided into primary oil-consuming lubrication points and secondary oil-consuming lubrication points according to the consumption of grease; the oil outlet of the first progressive distributor 11 is connected to the primary oil-consuming lubrication point, and the grease delivery amount of the first progressive distributor 11 matches the grease consumption of the primary oil-consuming lubrication point; the oil outlet of the second progressive distributor 12 is connected to the secondary oil-consuming lubrication point, and the grease delivery amount of the second progressive distributor 12 matches the grease consumption of the secondary oil-consuming lubrication point; the oil outlet of the lubrication pump is connected to the oil inlets of the first progressive distributor 11 and the second progressive distributor 12, and the lubrication pump delivers grease to the primary oil-consuming lubrication point and the secondary oil-consuming lubrication point respectively through the first progressive distributor 11 and the second progressive distributor 12.

[0034] In this embodiment, the lubrication points on the well repair machine are divided into primary lubrication points and secondary lubrication points according to the consumption of grease, and the grease is transported respectively through the first progressive distributor 11 and the second progressive distributor 12. Since the consumption of grease between the primary lubrication points connected to the first progressive distributor 11 is similar, the filling will be completed at a similar time point. The second progressive distributor 12 is in the same situation as the first progressive distributor 11, thereby reducing the waste of grease.

[0035] In this embodiment, the lubrication points are divided into two levels and grease is added separately, but in actual use, the lubrication points can also be divided into more levels to improve the consistency of grease consumption of lubrication points in the same level and better reduce grease waste.

[0036] In some embodiments, in combination Figure 2 As shown, the overhead travelling crane of the workover rig is equipped with a guide rope wheel, an auxiliary wheel and a sand bailing wheel. The guide rope wheel is provided with four first-level oil-consuming lubrication points, the auxiliary wheel is provided with four first-level oil-consuming lubrication points, and the sand bailing wheel is provided with one first-level oil-consuming lubrication point. The nine first-level oil-consuming lubrication points are connected one-to-one with the nine oil outlets of the first progressive distributor 11. The consumption of grease by the above-mentioned lubrication points is basically the same, and the consumption is significantly less than the consumption of the main pulley and other positions on the overhead travelling crane of the workover rig, so these lubrication points are classified as first-level oil-consuming lubrication points.

[0037] In some embodiments, in combination Figure 3 As shown, the overhead travelling carriage of the well repair rig is equipped with a main pulley and a fast rope pulley, the main pulley is provided with six secondary oil-consuming lubrication points, the fast rope pulley is provided with one secondary oil-consuming lubrication point, the seven secondary oil-consuming lubrication points are connected one-to-one to the seven oil outlets of the second progressive distributor 12, the lubrication points on the fast rope pulley consume substantially the same amount of grease as the six lubrication points on the main pulley, and therefore these lubrication points are classified as secondary oil-consuming lubrication points.

[0038] In some embodiments, in combination Figure 1 As shown, the intelligent centralized lubrication system for the well repair rig also includes a pressure switch assembly 2 connected in series between the lubrication pump and the first progressive distributor 11 and the second progressive distributor 12. The function of the pressure switch assembly 2 is to monitor the operation of the oil circuit and to close when the lubrication pump is shut down to prevent grease backflow.

[0039] In some embodiments, in combination Figure 5 As shown, the pressure switch assembly 2 includes a pressure valve 21 and a pressure gauge 22. The pressure gauge 22 is arranged on the pressure valve 21. The pressure valve 21 controls the conduction and closing of the oil circuit. The pressure gauge 22 helps the operator observe the operation of the oil circuit.

[0040] In some embodiments, in combination Figure 1 As shown, the lubrication pump is connected to the first progressive distributor 11 and the second progressive distributor 12 through the oil collecting block 31, and each oil inlet and outlet port of the oil collecting block 31 is connected in series with the pressure switch assembly 2. The lubrication pump realizes simultaneous oil supply to the first progressive distributor 11 and the second progressive distributor 12 through the oil collecting block 31, and the design of unlimited flow inside the oil collecting block 31 realizes oil supply to two oil circuits with different flow rates, and the closure of any one of the two oil circuits will not affect the oil supply to the other oil circuit.

[0041] In some embodiments, in combination Figure 1 , Figure 4 As shown, the pipe joint used between the lubrication pump and the oil collecting block 31 is a ferrule type pipe joint, which is simple to connect and has a long disassembly and assembly life, and can achieve adaptation to the flow of the lubrication pump.

[0042] In some embodiments, in combination Figure 4 As shown, the intelligent centralized lubrication system for the well repair rig also includes a work vehicle 4, the lubrication pump is integrated in the work vehicle 4, the first progressive distributor 11 and the second progressive distributor 12 are assembled on the overhead crane of the well repair rig, and the mobile use of the lubrication pump is realized through the work vehicle 4 to reduce the equipment cost. The first progressive distributor 11 and the second progressive distributor 12 are fixed in position to reduce the time cost of laying the equipment, and the oil circuit can be connected by only completing the clamping through the compression sleeve type pipe joint.

[0043] In some embodiments, in combination Figure 6 As shown, the intelligent centralized lubrication system for the well repairing machine also includes an oil filling pipe 32, and the first progressive distributor 11 and the second progressive distributor 12 are connected to the primary oil-consuming lubrication point and the secondary oil-consuming lubrication point through the oil filling pipe 32. The oil filling pipes 32 of the first progressive distributor 11 connected to each primary oil-consuming lubrication point are of equal length, and the oil filling pipes 32 of the second progressive distributor 12 connected to each secondary oil-consuming lubrication point are of equal length. The length restriction of the oil filling pipe 32 can ensure that the grease is transported to each lubrication point at the same time, especially when the grease in the oil filling pipe 32 increases from zero to sufficient, the different grease transportation distances will result in different time points when the grease filling is completed, resulting in grease waste.

[0044] In some embodiments, in combination Figure 6 As shown, the first progressive distributor 11 and the second progressive distributor 12 are both equipped with a plunger detector 33. By installing the plunger detector 33, the operation of the entire distributor can be monitored, and the operator's monitoring of the equipment can be strengthened. Once a blockage occurs, an alarm can be issued.

[0045] Working process: the lubrication pump pumps the grease into the first progressive distributor 11 and the second progressive distributor 12, and the flow rate of the grease is not restricted in this process; the first progressive distributor 11 is connected to all the primary oil-consuming lubrication points, and the first progressive distributor 11 will deliver an equal amount of grease to each primary oil-consuming lubrication point, and the second progressive distributor 12 delivers grease to the secondary oil-consuming lubrication points in the same way; all the primary oil-consuming lubrication points complete the grease filling at the same time, the first progressive distributor 11 is closed, all the secondary oil-consuming lubrication points complete the grease filling at the same time, and the second progressive distributor 12 is closed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
