Description

Technical Field

[0001] The invention belongs to the technical field of electric winches, and in particular relates to an automatically maintained electric-driven logging winch. Background Art

[0002] The operating principle of an electric logging winch is relatively simple and efficient. It primarily relies on power generated by an electric motor, which drives the capstan through a transmission system. To raise the logging tool, the motor rotates forward, winding the capstan around a wire rope or cable, lifting the tool to the wellhead. To lower the tool, the motor rotates backward, releasing the wire rope or cable from the capstan, allowing the tool to descend under its own weight.

[0003] In an electric-driven logging winch, the most important component is the wire rope wound on the winch. Since the wire rope is subjected to a lot of gravity, winding and friction during long-term use, it needs to be maintained after a period of use. However, the existing maintenance method requires shutting down the device before operation, and it is impossible to achieve online cleaning of the wire rope surface wear, which urgently needs improvement.

[0004] When an electric logging winch is in production and use, it is often necessary to stop the electric logging winch urgently. In the existing technology, the winch is generally braked to stop urgently. Although this emergency stop method can make the winch stop rotating quickly, when the wire rope lacks a certain limit, the wire rope will be subjected to a large tensile force in an instant, which seriously affects the service life of the wire rope. Summary of the Invention

[0005] The object of the present invention is to provide an automatically maintained electrically driven logging drawworks to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatically maintained electric-driven logging winch, comprising a base plate, a fixed frame fixedly installed at a position near the rear side of the top of the base plate, a winch movably connected inside the fixed frame, a reciprocating wire arrangement mechanism located in front of the winch fixedly installed in the middle of the top of the base plate, a fixed disk located directly in front of the reciprocating wire arrangement mechanism on the front side of the top of the base plate, the fixed disk is connected to the base plate through the frame, a guide roller is movably sleeved inside the fixed disk, the guide roller rotates relative to the fixed disk, and the bottom end of the guide roller is provided with a fixed The collecting box is just below the plate, and through holes are provided on the left and right sides of the top of the fixed plate, and the insides of the through holes are movably sleeved with limit assemblies, and the bottom end of the collecting box is provided with an adjusting assembly, and the bottom end of the adjusting assembly is fixedly installed with a linkage assembly, and the left and right sides of the top of the linkage assembly are respectively connected to the two limit assemblies, and the bottom end of the adjusting assembly is fixedly connected to an oil storage tank, and the left and right sides of the oil storage tank near the bottom end are fixedly connected to oil pipes, and the other end of the oil pipe is connected to the limit assembly, and an oil pump is installed inside the oil storage tank, and lubricating oil is stored inside the oil storage tank.

[0007] Before use, the fixed end of the wire rope can be fixedly wound on the surface of the winch. At the same time, the free end of the wire rope needs to be passed through the reciprocating cable arrangement mechanism and wound around the outer side of the guide roller and then connected to the logging tool. The lubricating oil in the oil tank should be kept full to complete the preparation before use.

[0008] As a further technical solution of the present invention, a gear box is installed on the rear side of the winch, and a main motor is fixedly installed on the top of the gear box. The output end of the main motor is connected to the input end of the gear box, and the output end of the gear box is connected to the connecting shaft in the middle of the winch.

[0009] When winding or releasing the wire rope, the main motor can be turned on to output power to the gear box. After deceleration by the gear box, the power is output to the capstan. At this time, the capstan rotates relative to the fixed frame, and the reciprocating cable arrangement mechanism at the front end can drive the wire rope to move back and forth left and right, so that the wire rope is evenly laid on the surface of the capstan to complete the winding or releasing process.

[0010] As a further technical solution of the present invention, the regulating assembly includes a regulating tube, a three-way valve is fixedly installed at the bottom end of the regulating tube, the bottom end of the three-way valve is connected to the top of the oil storage tank, and the left and right sides of the regulating tube near the top are fixedly connected with branch pipes, and the other end of the branch pipes is connected to the left and right ends of the three-way valve.

[0011] As a further technical solution of the present invention, the internal movable sleeve of the regulating tube is provided with a piston plate, the top end of the piston plate is fixedly connected to a piston rod located inside the regulating tube, the top end of the piston rod passes through the top end of the regulating tube and is fixedly connected to the linkage assembly.

[0012] As a further technical solution of the present invention, the outer side surface of the piston rod is movably sleeved with a limit spring, and the upper and lower ends of the limit spring are fixedly connected to the top of the inner cavity of the regulating tube and the top of the piston plate respectively. When the limit spring is in the initial state, the piston plate is located below the input end of the branch pipe.

[0013] When the wire rope needs to be self-maintained, the oil pump inside the oil tank can be turned on to extract the lubricating oil inside the oil tank into the inside of the three-way valve, and at the same time, it is discharged through the branch pipes at the left and right ends of the three-way valve, and introduced into the left and right positions of the top end of the inner cavity of the regulating tube through the branch pipes. At this time, the piston plate is pressurized, and the piston plate and the piston rod are driven down. At this time, the limit spring is stretched, and the force can be applied to the linkage assembly.

[0014] As a further technical solution of the present invention, the linkage assembly includes a movable plate, the middle part of the bottom end of the movable plate is connected to the top end of the piston rod, and first fixed seats are fixedly installed on the left and right sides of the top end of the movable plate. The end of the first fixed seat away from the movable plate is movably connected to a connecting rod through a rotating shaft.

[0015] As a further technical solution of the present invention, the end of the connecting rod away from the first fixed seat is movably connected to the second fixed seat through a rotating shaft, and the top of the second fixed seat is fixedly installed with an extension rod, which is connected to the limit assembly.

[0016] When the piston rod moves downward, the movable plate moves downward accordingly. At this time, the two connecting rods at the top of the movable plate are subjected to a downward pulling force, and drive the two connecting rods to deflect toward the middle. At this time, they can act on the two extension rods, driving the two extension rods to move relatively close.

[0017] As a further technical solution of the present invention, the limiting assembly includes a mounting rod, the left side of the bottom end of the mounting rod is connected to the extension rod, the limiting assembly also includes a limiting guide rail, one side of the limiting guide rail is connected to the fixed plate, the top end of the mounting rod is fixedly connected to a guide block, and the mounting rod is movably connected to the limiting guide rail through the guide block.

[0018] As a further technical solution of the present invention, the side of the mounting rod close to the fixed plate is fixedly connected to a limiting block, the limiting block is movably engaged with the through hole, and the limiting block is displaced left and right relative to the through hole.

[0019] When performing self-maintenance of the wire rope, due to the relative proximity of the two extension rods, the two mounting rods can be relatively close to each other under the action of the two extension rods. At this time, the limit block is displaced relative to the through hole, which can drive the two limit blocks to be relatively close until the two limit blocks contact the two ends of the wire rope. At this time, the two limit blocks can rub the outer side surface of the wire rope to remove the worn part of the wire rope surface, completing the self-maintenance process of the wire rope.

[0020] By utilizing the coordination between the oil storage tank and the adjustment component, as well as the coordination between the linkage component and the limit component, the device can automatically maintain the surface of the wire rope by turning on the oil pump inside the oil storage tank during the winding and releasing process of the wire rope. The entire process can be completed quickly without the need for traditional devices to shut down for maintenance, significantly improving maintenance efficiency.

[0021] When it is necessary to stop releasing or reeling in the wire rope, first, the output power can be stopped through the main motor and gear box, and the external brake device can be used to clamp the winch. At the same time, the lubricating oil inside the input regulating tube can be increased. At this time, the distance between the two extension rods continues to shorten, which drives the two limit blocks to continue to move closer to each other until the two limit blocks and the wire rope are in close contact, completing the pressure and friction. The friction force causes the wire rope to slowly stop moving, reducing the pressure on the wire rope.

[0022] By re-coordinating the adjustment component, linkage component and limit component, the device can not only realize the automatic maintenance of the wire rope, but also realize the friction stop operation of the wire rope by increasing the input of lubricating oil. The whole process can be completed quickly, which can avoid the problem of excessive pressure on the wire rope and reduced service life caused by the lack of limit of the wire rope when the traditional device stops suddenly, and significantly improve the service life of the device.

[0023] As a further technical solution of the present invention, an oil delivery channel is provided inside the mounting rod and the limiting block, and the oil delivery channel is fixedly connected to the oil delivery pipe.

[0024] At the same time, when maintaining the wire rope, the oil pump inside the oil storage tank can be turned on, and the valve inside the oil pipe can be opened. At this time, the lubricating oil can be discharged through the oil pipe and discharged through the oil channel to directly act on the surface of the wire rope to complete self-lubrication. At the same time, the lubricating oil can take away impurities worn during self-maintenance, enter the interior of the collection box for temporary storage, and evenly apply lubricating oil to the surface of the wire rope to complete the further maintenance process.

[0025] By directly draining the lubricating oil from the oil tank and coordinating the self-maintenance process, the surface of the wire rope can be evenly lubricated. At the same time, the spraying of lubricating oil can directly take away the debris and complete the auxiliary cleaning process. The entire process can be completed online, which can realize the maintenance and care of the wire rope without stopping the machine, further improving the maintenance efficiency and the service life of the wire rope.

[0026] The beneficial effects of the present invention are as follows:

[0027] (1) The present invention utilizes the cooperation between the oil storage tank and the adjustment component, as well as the cooperation between the linkage component and the limit component, so that the device can automatically maintain the surface of the wire rope by turning on the oil pump inside the oil storage tank during the winding and releasing process of the wire rope. The entire process can be completed quickly without the need for traditional devices to stop for maintenance, thereby significantly improving maintenance efficiency.

[0028] (2) The present invention coordinates the adjustment component, the linkage component and the limit component again, so that the device can realize the friction stop operation of the wire rope by increasing the input amount of lubricating oil on the basis of realizing automatic maintenance of the wire rope. The whole process can be completed quickly, which can avoid the problem that when the traditional device stops suddenly, the wire rope is not limited and is easily subjected to excessive pressure on the wire rope, resulting in a decrease in service life, thereby significantly improving the service life of the device.

[0029] (3) The present invention can achieve uniform lubrication of the surface of the wire rope by directly draining the lubricating oil from the oil storage tank and coordinating with the self-maintenance process. At the same time, the spraying of lubricating oil can directly take away debris and complete the auxiliary cleaning process. The entire process can be completed online, and the maintenance and care of the wire rope can be achieved without stopping the machine, further improving the maintenance efficiency and the service life of the wire rope.

An oil pump is installed inside the oil storage tank 11, and lubricating oil is stored inside the oil storage tank 11.

[0042] Before use, the fixed end of the wire rope can be fixedly wound on the surface of the winch 3. At the same time, the free end of the wire rope needs to be passed through the reciprocating cable arrangement mechanism 6 and wound around the outer side of the guide roller 7 and then connected to the logging tool. The lubricating oil in the oil storage tank 11 should be kept full to complete the preparation before use.

[0043] like Figure 1 As shown, a gear box 5 is installed on the rear side of the winch 3, and a main motor 4 is fixedly installed on the top of the gear box 5. The output end of the main motor 4 is connected to the input end of the gear box 5, and the output end of the gear box 5 is connected to the connecting shaft in the middle of the winch 3.

[0044] When winding or releasing the wire rope, the main motor 4 can be turned on to output power to the gear box 5, and after deceleration by the gear box 5, the power is output to the capstan 3. At this time, the capstan 3 rotates relative to the fixed frame 2, and the reciprocating wire arrangement mechanism 6 at the front end can drive the wire rope to move back and forth left and right, so that the wire rope is evenly laid on the surface of the capstan 3 to complete the winding or releasing process.

[0045] like Figure 2 and Figure 5 as well as Figure 6As shown, the regulating assembly 13 includes a regulating tube 131, a three-way valve 135 is fixedly installed at the bottom end of the regulating tube 131, and the bottom end of the three-way valve 135 is connected to the top of the oil storage tank 11, and the left and right sides of the regulating tube 131 near the top are fixedly connected with branch pipes 136, and the other end of the branch pipe 136 is connected to the left and right ends of the three-way valve 135. The interior of the regulating tube 131 is movably sleeved with a piston plate 132, and the top end of the piston plate 132 is fixedly connected to a piston rod 133 located inside the regulating tube 131. The top end of the piston rod 133 passes through the top end of the regulating tube 131 and is fixedly connected to the linkage assembly 14. The outer side surface of the piston rod 133 is movably sleeved with a limit spring 134, and the upper and lower ends of the limit spring 134 are fixedly connected to the top end of the inner cavity of the regulating tube 131 and the top end of the piston plate 132 respectively. When the limit spring 134 is in the initial state, the piston plate 132 is located below the input end of the branch pipe 136.

[0046] When the wire rope needs to be self-maintained, the oil pump inside the oil tank 11 can be turned on to extract the lubricating oil inside the oil tank 11 into the inside of the three-way valve 135, and at the same time, it is discharged through the branch pipes 136 at the left and right ends of the three-way valve 135, and introduced into the left and right positions of the top end of the inner cavity of the regulating tube 131 through the branch pipes 136. At this time, the piston plate 132 is pressurized, and the piston plate 132 and the piston rod 133 are driven to descend. At this time, the limit spring 134 is stretched, and the force can be applied to the linkage assembly 14.

[0047] like Figure 2 and Figure 5 as well as Figure 7 As shown, the linkage assembly 14 includes a movable plate 141, the middle part of the bottom end of the movable plate 141 is connected to the top end of the piston rod 133, and the left and right sides of the top end of the movable plate 141 are fixedly installed with a first fixed seat 142, the end of the first fixed seat 142 away from the movable plate 141 is movably connected to a connecting rod 145 through a rotating shaft, and the end of the connecting rod 145 away from the first fixed seat 142 is movably connected to a second fixed seat 143 through a rotating shaft, and the top end of the second fixed seat 143 is fixedly installed with an extension rod 144, which is connected to the limit assembly 15.

[0048] When the piston rod 133 moves downward, the movable plate 141 moves downward accordingly. At this time, the two connecting rods 145 at the top of the movable plate 141 are then subjected to a downward pulling force, and the two connecting rods 145 are driven to deflect toward the middle, which can then act on the two extension rods 144, driving the two extension rods 144 to move relatively close.

[0049] like Figure 2 and Figure 5 as well as Figure 8As shown, the limiting assembly 15 comprises a mounting rod 151, the left side of the bottom end of the mounting rod 151 is connected between the extension rods 144, the limiting assembly 15 further comprises a limiting guide rail 152, one side of the limiting guide rail 152 is connected between the fixed disc 8, the top end of the mounting rod 151 is fixedly connected with a guide block 153, the mounting rod 151 is movably clamped between the guide block 153 and the limiting guide rail 152, the side of the mounting rod 151 close to the fixed disc 8 is fixedly connected with a limiting block 154, the limiting block 154 is movably clamped between the limiting block 154 and the through hole 9, and the limiting block 154 is displaced left and right relative to the through hole 9.

[0050] In the self-maintenance of the steel wire rope, due to the relative close of the two extension rods 144, the two mounting rods 151 can be relatively close under the action of the two extension rods 144, at this time, the limiting block 154 is displaced relative to the through hole 9, which can drive the two limiting blocks 154 to be relatively close, until the two limiting blocks 154 contact the two ends of the steel wire rope, at this time, the two limiting blocks 154 can rub the outer side of the steel wire rope to remove the worn part on the surface of the steel wire rope, and the self-maintenance process of the steel wire rope is completed.

[0051] By utilizing the cooperation between the oil storage tank 11 and the adjusting assembly 13, and the cooperation between the linkage assembly 14 and the limiting assembly 15, the device can automatically maintain the surface of the steel wire rope by starting the oil pump inside the oil storage tank 11 during the winding and releasing of the steel wire rope, and the whole process can be quickly completed without the need for traditional devices to stop for maintenance, which significantly improves the maintenance efficiency.

[0052] When it is necessary to stop the release or winding of the steel wire rope, first, the main motor 4 and the gear box 5 can be stopped to output power, and an external brake device can be used to brake the capstan 3, and at the same time, the input of lubricating oil into the adjusting pipe 131 can be increased, at this time, the distance between the two extension rods 144 continues to shorten, which drives the two limiting blocks 154 to continue to approach each other, until the two limiting blocks 154 and the steel wire rope are in close contact, the pressure and friction are completed, and the steel wire rope is slowly stopped by the friction force, reducing the pressure on the steel wire rope.

[0053] By re-cooperating the adjusting assembly 13, the linkage assembly 14 and the limiting assembly 15, the device can realize the friction stopping operation of the steel wire rope on the basis of realizing the automatic maintenance of the steel wire rope, and the whole process can be quickly completed, which can avoid the problem that the traditional device is stopped suddenly, the steel wire rope is not limited, and the steel wire rope is easily pressed too much to cause the service life to decrease, and the service life of the device is significantly improved.

[0054] As Figure 2 and Figure 9As shown, an oil delivery channel 155 is provided inside the mounting rod 151 and the limiting block 154 , and the oil delivery channel 155 is fixedly connected to the oil delivery pipe 12 .

[0055] At the same time, when maintaining the wire rope, the oil pump inside the oil storage tank 11 can be turned on, and the valve inside the oil pipe 12 can be opened. At this time, the lubricating oil can be discharged through the oil pipe 12 and discharged through the oil delivery channel 155 to directly act on the surface of the wire rope to complete self-lubrication. At the same time, the lubricating oil can take away impurities worn during self-maintenance, enter the interior of the collection box 10 for temporary storage, and evenly apply the lubricating oil to the surface of the wire rope to complete the further maintenance process.

[0056] By directly draining the lubricating oil inside the oil storage tank 11 and coordinating the self-maintenance process, uniform lubrication of the surface of the wire rope can be achieved. At the same time, the spraying of lubricating oil can directly take away debris and complete the auxiliary cleaning process. The entire process can be completed online, and the maintenance and care of the wire rope can be achieved without stopping the machine, further improving the maintenance efficiency and the service life of the wire rope.

[0057] Working principle and usage process:

[0058] Before use, the fixed end of the wire rope can be fixedly wound on the surface of the winch 3. At the same time, the free end of the wire rope needs to be passed through the reciprocating cable arrangement mechanism 6 and wound around the outer side of the guide roller 7 and then connected to the logging tool. The lubricating oil in the oil tank 11 should be kept full. Preparations before use are completed.

[0059] When winding or releasing the wire rope, the main motor 4 can be turned on to output power to the gear box 5. After deceleration by the gear box 5, the power is output to the capstan 3. At this time, the capstan 3 rotates relative to the fixed frame 2, and the reciprocating wire arrangement mechanism 6 at the front end can drive the wire rope to move back and forth left and right, so that the wire rope is evenly laid on the surface of the capstan 3 to complete the winding or releasing process.

[0060] When the wire rope needs to be self-maintained, the oil pump inside the oil storage tank 11 can be turned on to extract the lubricating oil inside the oil storage tank 11 into the interior of the three-way valve 135, and at the same time, it is discharged through the branch pipes 136 at the left and right ends of the three-way valve 135, and introduced into the left and right positions of the top end of the inner cavity of the regulating tube 131 through the branch pipes 136. At this time, the piston plate 132 is pressurized, and the piston plate 132 and the piston rod 133 are driven to descend. At this time, the limit spring 134 is stretched, and the acting force can be applied to the linkage assembly 14;

[0061] When the piston rod 133 moves downward, the movable plate 141 moves downward accordingly. The two connecting rods 145 at the top of the movable plate 141 are then subjected to a downward pulling force, which drives the two connecting rods 145 to deflect toward the middle. At this time, the two connecting rods 145 can act on the two extension rods 144, driving the two extension rods 144 to move closer together.

[0062] When the wire rope is self-maintained, due to the relative proximity of the two extension rods 144, the two mounting rods 151 can be relatively close to each other under the action of the two extension rods 144. At this time, the limit block 154 is displaced relative to the through hole 9, which can drive the two limit blocks 154 to be relatively close to each other until the two limit blocks 154 contact the two ends of the wire rope. At this time, the two limit blocks 154 can rub the outer side surface of the wire rope to remove the worn part of the wire rope surface, completing the self-maintenance process of the wire rope;

[0063] When it is necessary to stop releasing or reeling in the wire rope, the main motor 4 and the gear box 5 can first stop outputting power, and the external brake device can be used to brake the winch 3. At the same time, the lubricating oil inside the input regulating tube 131 can be increased. At this time, the distance between the two extension rods 144 continues to shorten, that is, the two limit blocks 154 are driven to move closer together until the two limit blocks 154 and the wire rope are in close contact, completing the pressure and friction. The friction force causes the wire rope to slowly stop moving, reducing the pressure on the wire rope.

[0064] At the same time, when maintaining the wire rope, the oil pump inside the oil storage tank 11 can be turned on, and the valve inside the oil pipe 12 can be opened. At this time, the lubricating oil can be discharged through the oil pipe 12 and discharged through the oil delivery channel 155 to directly act on the surface of the wire rope to complete self-lubrication. At the same time, the lubricating oil can take away impurities worn during self-maintenance, enter the interior of the collection box 10 for temporary storage, and evenly apply the lubricating oil to the surface of the wire rope to complete the further maintenance process.

[0065] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
