Description

Technical Field

[0001] The invention belongs to the technical field of fiber ropes and cables, and particularly relates to a rope and cable joint structure for a high-strength oilfield nodding machine and an installation method. Background Art

[0002] Nowadays, when oil fields are mined, since oil fields and oil wells are relatively concentrated, oil field kowtow machines are needed to pump oil from them. Oil field kowtow machines are also called petroleum pumping machines. They are a device used to pump oil in oil fields. The rope joints used in oil field kowtow machines are mostly connected to the joints through steel cables. Although the ropes made of steel have higher strength, they also increase the weight of the ropes, resulting in increased lifting weight during work. The joints connected by traditional chemical fiber ropes have low connection strength, and the chemical fiber ropes are easily separated from the joints, which brings inconvenience to use. Summary of the invention

[0003] The object of the present invention is to provide a high-strength oilfield kowtow machine rope cable joint structure and installation method to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A high-strength oilfield kowtow machine rope cable joint structure and installation method, comprising:

[0006] A cable body and a joint seat connected to the cable body, wherein the joint seat is arranged in a cylindrical shape, specifically a stepped cylinder, the cable body comprises a cable braided segment 1, a cable dispersion segment 1 and a cable braided segment 2, the cable braided segment 1 and the cable braided segment 2 are cables braided from multiple groups of cable dispersion segments, one end of the cable braided segment 1 is connected to multiple groups of the cable dispersion segment 1, and one end of the multiple groups of the cable dispersion segment 1 are all connected to the cable braided segment 2;

[0007] The interior of the joint seat is provided with an inner sleeve for fixing the cable body, the interior of the joint seat is provided with an installation cavity that cooperates with the inner sleeve, which is conducive to the inner sleeve of the cable body being able to be stuck in the interior of the joint seat for installation. The interior of the inner sleeve is provided with a fixing cavity, which is conducive to fixing the end of the cable body. The lower end of the outer side of the inner sleeve is provided with a plurality of groups of lower through holes for the cable dispersion section 1 to pass through, and the upper end of the outer side of the inner sleeve is provided with a plurality of groups of upper through holes for the cable dispersion section 1 to pass through, the lower end of the cable dispersion section 1 is connected with the cable braided section 1, the upper end of the cable dispersion section 1 respectively passes through the lower end of the inner sleeve, the lower through holes and the upper through holes and is connected with the cable braided section 2, the cable braided section 2 is located inside the inner sleeve, and the inner sleeve and the interior of the joint seat are both provided with glue, which plays the role of glue bonding and curing, thereby improving the connection strength between the cable body and the joint seat.

[0008] Preferably, the volume of the installation cavity is larger than that of the inner sleeve, which is conducive to installing the inner sleeve and also to leaving a gap between the installation cavity and the inner sleeve after the inner sleeve is installed, which is conducive to glue injection.

[0009] Preferably, the lower through holes and the upper through holes are both arranged in eight groups, and correspondingly, the cable dispersion segment one is also arranged in eight groups corresponding thereto, so that the cable dispersion segment one can pass through the lower through holes and the upper through holes respectively and then be woven into the cable braided segment two. It should be noted that the lower through holes and the upper through holes are both smoothed to reduce friction with the ropes and cables.

[0010] Preferably, an annular pressure plate is further provided at the inner bottom end of the inner sleeve, and the annular pressure plate is arranged in a circular ring shape. The cable dispersion section 1 includes a winding section, and the winding section is arranged on the annular pressure plate, that is, each group of cable dispersion section 1 is wound around the annular pressure plate at least once, and then passes through the lower through hole and the upper through hole in sequence and is woven into a cable braided section 2. By arranging the winding section on the annular pressure plate, when the cable body is subjected to force, part of the force can be transferred to the annular pressure plate inside the inner sleeve, thereby further improving the connection strength between the cable body and the joint seat.

[0011] Preferably, a clamping component is further provided inside the inner sleeve, which can clamp the annular pressure plate so that the winding section can be tightly pressed between the annular pressure plate and the inner wall of the bottom end of the inner sleeve to prevent the rope from loosening. The clamping component includes a hinge ring, a hanging rod, a pressure rod and an arc-shaped hook. A hinge ring is installed on the inner wall of the inner sleeve, and the hinge ring is hinged with a connecting ring so that it can rotate. The outer sides of the connecting ring are respectively and integrally connected with the hanging rod and the pressure rod. An angle is formed between the hanging rod and the pressure rod, and the angle is greater than 90 degrees. An arc-shaped hook is connected to the side of the hanging rod close to the inner wall of the inner sleeve, which is conducive to cooperating with the circular hook of the rope and cable to fix the end of the second braided segment of the rope to the inside of the inner sleeve. The arc hook is set to an arc-shaped structure with a certain arc, so that the circular hook is not easy to fall off when hung thereon, and a pressing groove matching the pressing rod is opened at the upper end of the annular pressing plate. When the pressing rod rotates, it can slide inside the pressing groove and press the annular pressing plate downward, so as to press the winding section on the annular pressing plate tightly against the inner wall of the inner sleeve, thereby improving the strength of the rope connection. An opening is provided at one end of the pressing groove close to the inner ring of the annular pressing plate, which is conducive to the end of the pressing rod entering the pressing groove and sliding. Correspondingly, a stopper is provided at the other end of the pressing groove to prevent the end of the pressing rod from escaping from the inside of the pressing groove when moving toward the outside of the annular pressing plate. It should be noted that the pressing groove and the winding section are not in the same position to avoid mutual influence.

When installing, first put one end of the cable braided section 2 connected to the cable dispersion section 2 into the inner sleeve, and make the circular hook hang on the arc hook;

[0013] In the initial state, the hanging rod is located on the side close to the inner wall of the inner sleeve, the central axis of the connection point between the circular hook and the arc hook is far away from the central axis of the second cable braided segment, and the end of the pressure rod is located inside the pressure groove, that is, close to the inner circle of the annular pressure plate;

[0014] When the first braided cable segment is stressed, the force is transmitted in turn to the second cable dispersion segment and the circular hook at the second end of the braided cable segment, further tightening the arc hook, and then driving the hanging rod to rotate through the arc hook, so that the central axis of the connection point between the circular hook and the arc hook moves toward the central axis close to the second braided cable segment. The rotation of the hanging rod also further drives the pressure rod to rotate, so that the pressure rod further presses the annular pressure plate downward, thereby making the winding section tightly stuck between the annular pressure plate and the inner wall of the inner sleeve, which can further prevent the rope body from separating from the inner sleeve; further, when the glue inside the inner sleeve is not sufficient to support the connection of the rope body with the joint seat and the inner sleeve, the mutual cooperation between the provided hooks and the annular pressure plate improves the connection strength between the rope and the joint.

[0015] Preferably, the cable dispersion section 2 is provided with at least two groups, and correspondingly, the hanging rods and the pressure rods are also provided with at least two groups matched therewith, so as to avoid excessive occupation of the cavity inside the inner sleeve.

[0016] Preferably, the inner ring and the outer ring of the annular pressure plate are both configured as smooth arc surfaces to avoid wear between the increased edges and corners and the cables, thus playing a protective role.

[0017] Preferably, a method for installing a high-strength oilfield kowtow machine cable joint structure comprises the following steps:

[0019] S2, then put one end of the second braided cable segment connected with the circular hook into the interior of the inner sleeve, and hang the circular hook on the arc-shaped hook on one side of the hanging rod through the external thin rod hook, at this time, the hanging rod and the pressure rod rotate to a certain extent due to the tension of the rope, and the pressure rod also exerts a certain downward pressure on the annular pressure plate, so that the winding segment is tightly stuck between the annular pressure plate and the inner wall of the inner sleeve to prevent the rope from loosening, and at this time, the second braided cable segment is driven to enter the interior of the inner sleeve as a whole, and the end of the pressure rod is located inside the pressure groove of the annular pressure plate;

[0020] S3. Inject glue into the inner sleeve to solidify it. At this time, plug the holes of the inner sleeve to prevent leakage of glue. After the glue inside the inner sleeve solidifies, the cable body is fixedly connected to the inner sleeve. Then, pass the lower end of the first braided cable segment through the inside of the joint seat until the inner sleeve connected to the cable body is stuck in the inside of the joint seat. Then, inject glue into the inside of the joint seat again and wait for it to solidify. Then the installation is completed.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention improves the connection strength between the cable dispersed section and the inner sleeve by successively passing the cable dispersed section 1 at the end of the cable braided section 1 through the interior of the inner sleeve, the lower through hole and the upper through hole and then braiding it into the cable braided section 2, which makes it difficult for the cable to detach from the joint; and further improves the connection strength between the cable and the inner sleeve by installing the cable braided section 2 that is again braided into a cable inside the inner sleeve and injecting glue; the annular pressure plate and the clamping component that are provided in combination increase the connection strength between the cable end and the interior of the inner sleeve, making it difficult for the cable body to detach from the inner sleeve; the inner sleeve that is provided in combination is stuck in the interior of the joint seat and injected with glue, which further improves the connection strength between the joint seat and the inner sleeve. The cable body of the present invention adopts chemical fiber rope, which ensures the connection strength and is light in weight compared with traditional steel cables. The lifting weight is reduced during use, which is convenient for use. BRIEF DESCRIPTION OF THE DRAWINGS
