Description

Technical Field

[0001] The present invention relates to the technical field of downhole testing in oil fields, and particularly to a gear-driven testing wire rope knot knitting machine. Background Art

[0002] Wire rope knots play a crucial role in the process of winch controlling downhole instruments. The knitting quality of the knots determines the magnitude of the tensile force that the knots can withstand. The higher the knitting quality of the knots, the greater the tensile force they can withstand, and the higher the success rate of releasing the stuck state of the downhole instrument when the downhole instrument gets stuck. The wire rope knots currently used in the injection well testing site are usually manually knitted by workers using simple tools such as pliers according to the construction standards. Their knitting quality depends on the experience and technical level of the workers, and the work efficiency and success rate cannot be guaranteed.

[0003] In the prior art, there is a fast testing wire winding knotting device. However, during the process of knot knitting work, it is unable to process rings on the knots, and workers need to manually make rings on the wire rope. However, the diameter of the rings made manually is unstable. Rings that are too large or too small cannot be used normally on this device, and the influence of manual operation level on the knot knitting quality has not been eliminated. At the same time, in order to save effort, the length of its handle is too long, resulting in unstable center of gravity of the device and easy to tip over. Although the defect can be compensated by adding weights, the device after adding weights is too heavy to be easily transferred and moved and is not easy to be placed between the testing winch and the wellhead, and the operation location is limited. For the winding degree of the knots, it needs to be manually controlled by humans and needs to be operated according to the number of turns required for the knots. Too few or too many turns will affect the knot quality.

[0004] In addition, there is also an electric testing wire rope knot mechanical knitting machine. Although it can process knots on the wire rope by electric means, its working position is limited by the power supply and it needs to be equipped with a power supply to be used. When used in winter, the discharge performance of the carried power supply is greatly affected by the surrounding low-temperature environment, and power shortage often occurs, and the bearings and reduction gearbox gears in the motor are easily frozen in the low-temperature environment. This device rotates the rings of the knots through the motor, so it must be equipped with a decelerating low-speed motor to provide the power that meets the use requirements, and such a structure will cause the device to be too heavy to be easily carried. At the same time, when arranging the wires, the tightness of the wire arrangement still needs to be manually controlled for tightness control and adjustment, and its work is difficult, the workload is large, and the construction difficulty is large.

[0005] Therefore, in view of the above deficiencies, a gear-driven testing wire rope knot knitting machine is proposed. Summary of the Invention

The wire winding mechanism includes a wire forming cylinder. Fixing the wire in the wire forming cylinder and rotating with the main shaft realizes the winding of the wire rope knot. Above the main shaft, a wire arranging mechanism is provided. The wire arranging mechanism moves unidirectionally along the main shaft direction as the crank is shaken, and controls the tightness of the knot during the winding of the wire rope knot by contacting the wire. Next to the wire arranging mechanism, a wire walking limiting mechanism is provided to limit the position of the wire arranging mechanism. When the wire arranging mechanism is separated from the wire walking limiting mechanism, the wire arranging mechanism no longer moves unidirectionally.

[0014] Preferably, the wire limiting mechanism includes a limiting main body. A concentric telescopic rod is provided in the limiting main body. The telescopic rod extends from one end of the limiting main body and contacts the limiting column to stop the movement of the limiting column. A push key is provided at the other end of the limiting main body. Pressing the push key can push the telescopic rod outward. A locking button is provided on the limiting main body. After the telescopic rod extends, the locking button fixes the position of the telescopic rod. Pressing the locking button retracts the telescopic rod.

EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] In the description of the present invention, it is necessary to understand that the orientation or positional relationship indicated by "upper", "lower", "inner", "outer", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings. The purpose is only to facilitate the description of the present invention and simplify the description, rather than indicating or implying that the components referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0020] As Figure 1-7 shown, the present invention provides a gear-driven test wire rope knot knitting machine, which specifically includes: a fixed bracket 10. The fixed bracket 10 serves as the overall frame of the device, and other components of the device are installed on the fixed bracket 10 to form the overall device, maintaining the stability of the device. A main shaft bearing seat 71 with a horizontal direction is provided on the fixed bracket 10. A concentric main shaft 2 is provided inside the main shaft bearing seat 71. A main shaft bearing 72 is provided between the main shaft bearing seat 71 and the main shaft 2. The main shaft 2 serves as the main body of the device's movement and is connected to the main shaft bearing seat 71 through the main shaft bearing 72 and can rotate freely in the circumferential direction after being stressed. A concentric large reduction gear 3 is provided at one end of the main shaft 2. A small reduction gear 4 is provided beside the large reduction gear 3. The center of the small reduction gear 4 is connected to one end of a bent crank 1. Rotating the crank 1 drives the main shaft 2 to rotate through the transmission of the small reduction gear 4 and the large reduction gear 3. The cooperation of the large reduction gear 3 and the small reduction gear 4 effectively shortens the space required when shaking the crank 1, reduces the space required when using the device, and improves the practicality of the device. At the same time, the device achieves a reduction effect through the cooperation of the large reduction gear 3 and the small reduction gear 4, facilitating the control of the rotation speed and amplitude of the main shaft and preventing the excessive rotation speed of the main shaft from affecting the working effect of the device.

[0021] Among them, a standard wire length forming mechanism 6 is provided at the top of the fixed bracket 10. The length forming mechanism 6 includes a number of wire standard tubes 62. The internal space diameters between each wire standard tube 62 are different and the lengths meet the standard reserved lengths of the wires corresponding to the diameters. Inserting the wire into the wire standard tube 62 with the corresponding diameter can reserve the standard length for bending. During the working process, insert the wire into the wire standard tube 62 with the corresponding size. At this time, the length of the wire in the wire standard tube 62 is the short end that forms the wire rope knot when wound on the long end during the wire rope knot weaving. The remaining part is the long end. At this time, the length of the short end is the standard length for weaving the wire rope knot. After the wire rope knot is woven, the wire of the short end is just consumed without remainder. Even if the equipment continues to operate, the number of turns of the wire rope knot will not increase further, improving the success rate of wire rope knot weaving. Generally, when the wire is bent in the length forming mechanism 6, the bending angle is generally 30°, which is convenient for making a circular ring on the basis of the bending later.

[0022] It should be noted that a wire support 61 is provided below the wire standard tube 62. The lower part of the wire support 61 is connected to the fixed bracket 10 to fix the wire standard tube 62.

[0023] As Figure 2 shown, a circular ring making mechanism 5 is provided at the top of the fixed bracket 10. The wire circular ring making mechanism 5 includes a circular ring driving gear 51 and a circular ring driven gear 53. The circular ring driving gear 51 is installed on the main shaft 2 and is concentric with the main shaft. The circular ring driven gear 53 is horizontally placed beside the circular ring driving gear 51 and is in contact with the circular ring driving gear 51. A vertical central shaft 54 is provided at the center of the circular ring driven gear 53. When the crank 1 is shaken, the circular ring driving gear 51 rotates with the main shaft 2 and drives the circular ring driving gear 51 to rotate horizontally. The central shaft 54 rotates synchronously with the circular ring driven gear 53; a horizontally extending bending arm is provided on the central shaft 54, and a vertical upward fork 52 is provided on the bending arm. After the wire is fixed, the fork 52 rotates with the central shaft 54 to bend the wire around the central shaft 54 to form a circular ring.

[0024] Among them, a wire clamping angle 55 is provided beside the top of the central shaft 54 to cooperate with the top of the central shaft 54 to fix the wire. During the working process, press the long end of the wire against the wire clamping angle 55. Since the bending angle of the wire on the wire, the short end of the wire extends into the space between the wire clamping angle 55 and the central shaft 54. At this time, rotate the crank 1 to drive the circular ring driving gear 53 to drive the central shaft 54 and the fork 52 to rotate synchronously. The fork 52 pushes the short end of the wire to wind around the top of the central shaft 54 for one week to form a circular ring.

[0025] Generally, the bending angle of the short end of the steel wire is 30°. After the fork 52 pushes the short end of the steel wire to rotate 270° in the reverse direction around the central axis 54, a circular ring is formed. During the production process of the circular ring, the size and quality of the circular ring are not affected by the working technical level of the operator. Only by rotating the crank 1 in the specified direction can the production work of the circular ring be completed, improving the work efficiency and accuracy of the steel wire rope knot weaving work.

[0026] As Figure 4 shown, one end of the main shaft 2 is connected to the large reduction gear 3, and the other end is provided with a steel wire winding mechanism 7 for steel wire rope knot weaving. The steel wire winding mechanism 7 includes a circular ring fixing sleeve 74, a steel wire forming cylinder 75, and a sliding sleeve 76. The circular ring fixing sleeve 74 is installed at the end of the main shaft 2 and is concentric with the main shaft 2. The circular ring fixing sleeve 74 is provided with a through fixing hole, and a circular ring fixing pin 73 is provided in the fixing hole; during the working process, the circular ring of the steel wire with the circular ring made is inserted into the circular ring fixing sleeve 74, and the circular ring fixing pin 73 is inserted into the circular ring fixing sleeve 74. Adjust the direction of the steel wire circular ring so that the circular ring fixing pin 73 passes through the steel wire circular ring while passing through the fixing hole. At this time, the steel wire is fixed to the main shaft 2 and rotates with the rotation of the main shaft 2. The lower part of the sliding sleeve 76 is fixed on the fixed bracket 10. The steel wire forming cylinder 75 is concentrically arranged in the sliding sleeve 76 and is concentric with the main shaft 2. The upper surfaces of the steel wire forming cylinder 75 and the sliding sleeve 76 are provided with axially through steel wire grooves; after the steel wire is fixed in the circular ring fixing sleeve 74, the long end of the steel wire is lowered into the steel wire forming cylinder 75 and the sliding sleeve 76 along the steel wire groove, and the short end of the steel wire extends out from the top opening of the steel wire groove. The opening size at the top of the steel wire groove is larger than the opening size below the steel wire groove, and the woven steel wire rope knot can be taken out from the top opening of the steel wire groove. After the position of the steel wire forming cylinder 75 is fixed, rotate the crank 1 to drive the steel wire to rotate by the main shaft 2. When the short end of the steel wire is disengaged from the opening edge of the steel wire groove, the rotation stops, and the long end of the steel wire continues to rotate with the main shaft 2 and gradually winds the short end of the steel wire around the long end to form a steel wire rope knot.

[0027] Among them, an L-shaped fixing groove is provided on the side wall of the sliding sleeve 76, and a push rod 751 extending radially outward is provided on the outer wall of the steel wire forming cylinder 75. The size of the push rod 751 corresponds to the size of the fixing groove. In the non-working state, the push rod 751 is in the horizontal part of the L-shaped fixing groove. At this time, the positions of the steel wire grooves of the sliding sleeve 76 and the steel wire forming cylinder 75 correspond, and the steel wire can be normally inserted or taken out; during work, move the push rod 751 to the top of the vertical part of the L-shaped fixing groove. At this time, the position of the steel wire forming cylinder 75 is fixed on the sliding sleeve 76, preventing the position of the steel wire forming cylinder 75 from moving under force during the rope knot weaving process, resulting in unstable quality of the woven steel wire rope knot, improving the working efficiency of the device while maintaining the stability of the device.

[0028] It should be noted that the end of the wire forming cylinder 75 is provided with an anti-jump insertion rod 77. The surface of the anti-jump insertion rod 77 is provided with an axially penetrating wire groove. The outer diameter of the anti-jump insertion rod 77 is matched with the inner diameter of the wire forming cylinder 75. Usually, the anti-jump insertion rod 77 is installed at the end of the wire forming cylinder 75 and inserted into the wire forming cylinder 75. At this time, the position of the wire groove of the anti-jump insertion rod 77 corresponds to the wire groove position of the wire forming cylinder 75, and the long end of the wire can enter the wire forming cylinder 75 through the wire groove; after the long end of the wire enters the wire forming cylinder 75, the anti-jump insertion rod 77 is pulled out and turned downward by 180° and then re-inserted into the wire forming cylinder 75. At this time, the inside of the wire forming cylinder 75 is closed, preventing the long end of the wire from slipping out of the wire groove during the working process and causing the wire to come out of the groove, improving the practicability and safety of the device.

[0029] As Figure 5-6 shown, a wire arranging mechanism 8 is provided above the main shaft 2. The wire arranging mechanism 8 moves unidirectionally along the direction of the main shaft 2 as the crank 1 is shaken, and controls the tightness of the knot during the winding process of the wire rope knot by contacting the wire; when the crank 1 rotates, the short end of the wire gradually winds around the long end to form a wire rope knot. The wire arranging mechanism 8 clamps the short end of the wire and drives the short end of the wire to move unidirectionally along the main shaft 2 as the crank 1 rotates, so that the short end of the wire is evenly wound around the long end. By adjusting the movement amplitude of the wire arranging mechanism 8 as the crank 1 is shaken, the tightness of the wire rope knot can be adjusted, solving the problem that it is difficult for manual labor to control the tightness of the wire rope knot.

[0030] Among them, the wire arranging mechanism 8 includes a wire arranging driving gear 87, a wire arranging driven gear 86 and a fixed housing 83. The wire arranging driving gear 87 is installed on the main shaft 2 and is concentric with the main shaft 2. The wire arranging driving gear 87 contacts and is in transmission cooperation with the wire arranging driven gear 86. When the main shaft 2 rotates, the wire arranging driving gear 87 rotates with the main shaft 2 and drives the wire arranging driven gear 86 to rotate. A wire arranging main shaft 81 is arranged in the fixed housing 83. The wire arranging main shaft 81 is parallel to the main shaft 2. A wire arranging bearing 82 is arranged between the wire arranging main shaft 81 and the fixed housing 83. One end of the wire arranging main shaft 81 is connected to the center of the wire arranging driven gear 86, and the wire arranging main shaft 81 rotates synchronously with the wire arranging driven gear. The wire arranging bearing 82 reduces the friction between the wire arranging main shaft 81 and the fixed housing 83, reduces the wear degree during the use of the device, and prolongs the service life of the device; the other end of the wire arranging main shaft 81 is provided with a wire arranging wheel 85. The wire arranging wheel 85 is concentric with the wire arranging main shaft 81. The wire arranging wheel 85 is provided with a circumferential central groove. During the process of winding the wire knot, the short end of the wire extends into the central groove for clamping; usually, the wire rope knot consists of an inner ring and an outer ring. When the wire arranging wheel 85 moves along the direction of the wire arranging main shaft 2, it drives the short end of the wire to move synchronously. At this time, the short end of the wire is evenly wound on the long end to form an inner ring of the wire rope knot with a required tightness. Generally, the position of the wire arranging wheel 85 is directly above the wire forming cylinder 75. After the wire is installed in the wire fixing sleeve 74, the short end of the wire extends upward and just falls into the central groove of the wire arranging wheel 85.

[0031] In addition, the wire arranging wheel 85 and the wire arranging main shaft 81 are connected by threads. When the crank 1 is rotated, the wire arranging wheel and the wire arranging main shaft 81 rotate synchronously. At this time, the rotation of the wire arranging wheel 85 is blocked. Under the action of the threads, when the crank 1 rotates one week, the wire arranging wheel 85 screws out a certain distance along the main shaft to one side and drives the short end of the wire to move synchronously. The bottom of the short end of the wire is wound on the long end to form a wire rope knot. By adjusting the thread specifications between the wire arranging wheel 85 and the wire arranging main shaft 81, the moving distance of the wire arranging wheel 85 and the short end of the wire when the crank 1 rotates one week during the working process can be changed, so as to change the tightness of the wire rope knot after knitting.

[0032] It should be noted that the wire arranging wheel 85 is provided with a limiting column 84 extending outward. By blocking the rotation of the limiting column 84, the wire arranging wheel 85 cannot rotate. At this time, when the crank 1 is rotated, the wire arranging wheel 85 screws out. When the rotation of the limiting column 84 is not blocked, the wire arranging wheel 85 rotates synchronously with the wire arranging main shaft 81. At this time, the wire arranging wheel 85 stops moving. Continuing to rotate the crank 1, the remaining part of the short end of the wire is wound outward on the long end of the wire to form a wire rope knot. In this process, the part of the short end of the wire wound on the long end is the outer ring of the wire rope knot.

[0033] In the present invention, a wire walking limiting mechanism 9 is provided beside the wire arranging mechanism 8 to limit the position of the wire arranging mechanism 8. When the wire arranging mechanism 8 is separated from the wire limiting mechanism 9, the wire arranging mechanism 8 no longer moves unidirectionally. Usually, there are certain requirements for the number of turns of the inner and outer circles in the knitting of wire rope knots. By controlling the relative moving distance between the wire arranging mechanism 8 and the wire limiting mechanism 9, the number of turns of the inner circle of the wire rope knot can be controlled.

[0034] Among them, the wire limiting mechanism 9 includes a limiting main body 92. A concentric telescopic rod 94 is arranged inside the limiting main body 92. The telescopic rod 94 is parallel to the main shaft 2 and extends from one end of the limiting main body 92 to contact the limiting column 84 to stop the movement of the limiting column 84. When the limiting column 84 is separated from the telescopic rod 94, the telescopic rod 84 and the wire arranging wheel 85 rotate synchronously with the wire arranging main shaft 81. During the working process, the moving distance of the wire arranging wheel 85 is proportional to the number of turns of the crank 1, that is, proportional to the number of turns of the short end of the wire wound around the long end. By adjusting the length of the telescopic rod 94, the moving distance of the wire arranging wheel 85 along the direction of the main shaft 2 can be controlled, so as to control the number of turns of the inner circle of the short end of the wire wound around the long end. The limiting column 84 moves along the telescopic rod 84 with the wire arranging wheel 85. When the limiting column 84 moves to the end of the telescopic rod 94 and is separated from the telescopic rod 94, the limiting column 84 no longer stops the rotation of the wire arranging wheel 85. At this time, when the crank 1 is rotated continuously, the remaining part of the short end of the wire continues to wind around the long end to form the outer circle of the wire rope knot.

[0035] It should be noted that a push key 91 is provided at the other end of the limiting main body 92. Pressing the push key 91 can push the telescopic rod 94 outwards. A locking button 93 is provided on the limiting main body 92. After the telescopic rod 94 extends out, the locking button 93 fixes the position of the telescopic rod 94. After pressing the locking button 93, the telescopic rod 94 retracts. Through the cooperation of the push key 91 and the locking button 93, the position of the telescopic rod 94 can be fixed, preventing the length of the telescopic rod 94 from changing during the working process, resulting in unqualified knitting quality of the wire rope knot, and improving the working quality and stability of the device.

[0036] The gear-driven test wire rope knot knitting machine provided by the present invention can perform the full process of knitting wire rope knots for various types of wires. It is simple and stable to operate, saves manpower and working hours, can accurately control the tightness of the wire rope knot, and is convenient to carry. The specific operation process of the device is as follows: Step 1: Insert the wire into the wire standard tube with the corresponding diameter for bending. At this time, the part of the bent wire inside the wire standard tube is the short end, and the other side of the bending part is the long end.

[0037] Step 2: Clamp the short end of the wire in the wire clamping corner and rotate the crank. During this process, the crank drives the ring driven gear to rotate through the gear transmission mechanism, thereby driving the fork to rotate and push the short end of the wire to rotate around the central axis to form a ring.

[0038] Step 3: Remove the steel wire with the ring, put the ring of the steel wire into the ring fixing sleeve and insert the ring fixing pin to fix it. At this time, the ring fixing pin passes through the fixing hole and the ring at the same time to connect the steel wire to the main shaft, and when the main shaft rotates, it drives the steel wire to rotate synchronously.

[0039] Step 4: Put the long end of the steel wire into the steel wire forming cylinder through the steel wire groove, pull the push-pull rod to the top of the vertical part of the L-shaped fixed groove, and flip the anti-jump plug rod. At this time, the push-pull rod cooperates with the L-shaped fixed groove to fix the position of the steel wire forming cylinder. After the anti-jump plug rod is flipped, the steel wire forming cylinder is sealed to prevent the steel wire from falling out of the groove. The fixed short end of the steel wire rope extends vertically upward from the top of the steel wire groove.

[0040] Step 5. Clamp the short end of the wire rope in the center groove of the wire wheel, press the push button to extend the telescopic rod, adjust the wire wheel so that the limit column is against the telescopic rod, and shake the handle until the limit column is separated from the telescopic rod. In this process, when the handle is shaken, the main shaft drives the long end of the wire rope to rotate synchronously, the top of the wire groove fixes the direction of the short end of the wire rope, and the bottom of the short end is gradually wound to the long end; at the same time, the wire wheel moves unidirectionally along the main shaft direction under the action of the thread, and the limit column moves on the telescopic rod toward the end of the telescopic rod with the wire wheel. The moving distance is related to the number of turns of the crank. The wire wheel drives the short end of the wire to move while winding, so that the short end is wound on the long end according to a certain degree of tightness to form the inner circle of the wire rope knot. After the limit column and the telescopic rod are separated, the wire wheel stops moving, and the inner circle is completed.

[0041] Step 6: Continue to shake the handle until the short end is completely wrapped around the long end, and the wire rope knot is completed. At this point, the wire wheel does not move, and the short end of the wire is wound outward at the original position until the remaining short ends of the wire are all wrapped around the long end, forming the outer ring of the wire rope knot, and the wire rope knot is completed.
