Description

Technical Field

[0001] This invention relates to the field of oil extraction technology, and in particular to a method for arranging the steel wires in the manufacturing of the drive belt of a tower-type pumping unit. Background Technology

[0002] Tower pumping units (also called "tower pumping units" or "saddle-type pumping units") are a type of mechanical equipment widely used in the field of oil extraction. Their main function is to extract oil through reciprocating motion. They are commonly used in oil fields, especially in oil wells with low production or those requiring deep pumping. In special circumstances, they can also be used in offshore oil production projects.

[0003] The structure of a tower pumping unit typically includes a tower, drive system, transmission structure, wellhead equipment, oil tank, and pumping unit. The working principle of a tower pumping unit is based on the reciprocating motion of machinery. The drive motor causes the sucker rod (or pump rod) of the pumping unit to move up and down through the transmission system, extracting crude oil from the oil layer and transporting it to the surface through pipelines.

[0004] In existing technologies, transmission structures generally use belts as transmission components. These belts are steel cord conveyor belts, with a steel cord core padding and rubber covering the conveyor belt. They consist of an upper rubber layer, a lower rubber layer, and a core rubber layer. They are suitable for long-distance, high-capacity equipment. However, because they only use one core rubber layer, the strength of the conveyor belt is not high. During operation, the cross-section of the conveyor belt is subjected to uneven stress, which can easily cause damage to the conveyor belt. Summary of the Invention

[0005] Therefore, it is necessary to provide a method for arranging the steel wires in the drive belt of a tower-type pumping unit to address the problem of uneven cross-sectional stress on the belt in the current transmission structure during operation.

[0006] The above objectives are achieved through the following technical solutions: A method for arranging steel wires in the drive belt of a tower-type pumping unit, wherein the drive belt comprises, from top to bottom, an upper rubber layer, an aramid layer, a core rubber layer, an aramid layer and a lower rubber layer, and a row of parallel steel wire segments is arranged in the core rubber layer; The method for arranging the steel wires in the drive belt of the tower-type pumping unit includes the following specific steps: S100: Twist N steel wires together to form a single steel wire strand. Each steel wire strand has a single steel wire at its center and N-1 steel wires around it. N represents a positive integer. S200: M strands of steel wire are twisted together to form a steel wire rope. A steel wire rope has a single steel wire in the middle and M-1 steel wires on the outside. M represents a positive integer. S300: The wire rope has six parallel wire segments within the core layer, and the six wire segments are spaced at the same interval.

[0007] Furthermore, the drive belt is divided into left and right parts, and each of the left and right parts of the drive belt has three steel wire segments, which extend out of the upper and lower end faces of the drive belt. An upper connecting frame is provided on the upper end face of the drive belt, which connects to the upper end of the steel wire segments. A lower connecting frame is provided on the lower end face of the drive belt, which connects to the lower end of the steel wire segments.

[0008] Furthermore, the upper connecting frame is rotatably equipped with two upper pulleys, and two fixed rods are provided on the outer side of the two upper pulleys. The lower connecting frame is rotatably equipped with three lower pulleys. One end of the wire rope is fixed to one of the fixed rods, and after passing through the core rubber layer, the wire rope is wound around the two upper pulleys and the three lower pulleys in sequence. The other end of the wire rope is fixedly connected to the other fixed rod.

[0009] Furthermore, after passing through the core rubber layer of the left part of the drive belt, the wire rope is wound around the left side of the two upper pulleys and the three lower pulleys, and after passing through the core rubber layer of the right part of the drive belt, the wire rope is wound around the right side of the two upper pulleys and the three lower pulleys.

[0010] Furthermore, the outer circumferences of the rotating shafts of the two upper pulleys and the three lower pulleys are coaxial and fixedly connected to bearings, and the outer circumferences of the bearings are provided with fixing frames, which are fixedly mounted on the upper connecting frame or the lower connecting frame.

[0011] Furthermore, the shafts of the two upper pulleys are inclinedly mounted on the upper connecting frame, and the inclination angle and direction of the shafts of the two upper pulleys are the same. The steel wire ropes wrapped around the outer circumference of the two upper pulleys are inserted into the core rubber layer of the drive belt at the same horizontal straight line.

[0012] Furthermore, the end face of any one upper pulley makes sliding contact with the end face of the shaft of the adjacent upper pulley.

[0013] Furthermore, the upper connecting frame is provided with an upper connecting plate, which can be connected to the oil pumping pipe of the tower-type pumping unit.

[0014] Furthermore, the shafts of the three lower pulleys are inclined on the lower connecting frame, and the inclination angle and direction of the shafts of the three lower pulleys are the same. The steel wire ropes wrapped around the outer circumference of the three lower pulleys are inserted into the core rubber layer of the drive belt at the same horizontal straight line.

[0015] Furthermore, the two ends of the middle sliding wheel shaft slide in contact with the end faces of the adjacent sliding wheels.

[0016] Furthermore, a lower connecting plate is fixedly installed on the lower connecting frame, and the lower connecting plate can connect to heavy objects.

[0017] Furthermore, both N and M are 7.

[0018] Furthermore, the aramid layer is etched by plasma treatment, and adhesive active points are generated on the surface of the aramid layer, which is then bonded and fixed between the upper adhesive layer, the core adhesive layer and the lower adhesive layer.

[0019] The beneficial effects of this invention are: This invention increases the number of steel wire ropes distributed within the drive belt without increasing its thickness. This improves the tensile strength and service life of the drive belt, reduces the frequency of belt replacement, lowers the consumption of consumables such as rubber and steel, and reduces downtime caused by belt failure. It also reduces energy waste and carbon emissions during extraction, providing equipment support for low-carbon oil extraction.

[0020] This invention, through the arrangement of the wire rope and the setting of multiple upper and lower pulleys, enables the wire rope wound on the upper and lower pulleys to be evenly stressed. When one part of the left and right drive belts experiences different stresses than the other, the wire rope drives the upper and lower pulleys to rotate, thereby balancing the stress on the wire rope and ensuring that the overall stress on the wire rope is the same. This prevents uneven stress on the wire rope from affecting the drive belt. Even stress reduces abnormal wear on the drive belt, lowers equipment maintenance frequency and energy consumption, and avoids sudden failures caused by uneven stress, ensuring a stable and continuous mining process and meeting the high-efficiency and energy-saving requirements of low-carbon mining.

[0021] This invention avoids the need for clamping the drive belt by setting an upper connecting frame and a lower connecting frame at the upper and lower ends of the drive belt, and connecting the steel wire rope through the upper connecting frame and the lower connecting frame. This avoids the cumbersome clamping operation, simplifies the installation and maintenance process, reduces energy consumption and labor costs during maintenance, and further improves the low-carbon level of oil extraction.

[0027] The following reference Figures 1-13 This invention describes a method for arranging the steel wires in the drive belt of a tower-type pumping unit, specifically applicable to the steel wire arrangement inside the drive belt 100, which has multiple layers, such as... Figure 8As shown, from top to bottom, the layers are: upper rubber layer 110, aramid layer 120, core rubber layer 130, aramid layer 120, and lower rubber layer 140. The advantage of having multiple layers in the drive belt 100 is that it increases the tensile strength and service life of the drive belt 100, reduces replacement frequency, and lowers energy consumption. The upper rubber layer 110 and lower rubber layer 140 are the outer rubber layers of the belt, covering the upper and lower surfaces of the drive belt 100 respectively. They are typically made of rubber materials (such as neoprene rubber, abrasion-resistant rubber, etc.), and their main function is to enhance the friction of the drive belt 100, protect the inner layers, and provide a certain degree of wear resistance and anti-aging properties, extending service life and reducing energy consumption. Material consumption; while the aramid layer 120 is a high-strength material layer made of aromatic polyamide fiber, usually located in the middle or reinforcing layer of the drive belt 100. The aramid layer 120 has excellent mechanical properties, such as high strength, high temperature resistance and corrosion resistance, reducing material consumption; while the core rubber layer 130 is located between the aramid layer 120 and the upper rubber layer 110 and the lower rubber layer 140. It is the core layer of the drive belt 100, usually made of high-strength rubber material, which plays a role in reinforcing the overall structure, responsible for wrapping and fixing the aramid layer 120, providing additional strength and stability, ensuring long-term stable operation of the equipment, and reducing downtime energy consumption.

[0028] Furthermore, a row of parallel steel wire segments is arranged inside the core rubber layer 130. The parallel arrangement of the steel wire segments can further improve the tensile strength and service life of the drive belt 100. The steel wire arrangement method inside the core rubber layer 130 includes the following specific steps: Step S100: Twist N steel wires together to form a single steel wire strand 160. Each steel wire strand 160 has a single steel wire at its center and N-1 steel wires around its perimeter, where N is a positive integer.

[0029] In this embodiment, N=7 is used as an example, such as Figures 11-13 As shown, each strand of steel wire 160 consists of 7 steel wires, with a single steel wire in the middle and 6 steel wires on the periphery. This twisting structure reduces the redundant use of steel wires and lowers material consumption while ensuring strength.

[0030] Step S200: Twist and twist M strands of steel wire 160 into a steel wire rope 150. The steel wire rope 150 has a single steel wire strand 160 in the middle and M-1 strands of steel wire 160 on the outside, where M is a positive integer.

[0031] In this embodiment, M=7 is used as an example, such as Figures 11-13 As shown, a wire rope 150 consists of 7 wire strands 160. The optimized twisting structure ensures the high strength and flexibility of the wire rope 150, reduces the risk of breakage during use, and lowers maintenance energy consumption and carbon emissions.

[0032] Step S300: The wire rope 150 forms six parallel wire segments within the core rubber layer 130, and the six wire segments are spaced at the same interval.

[0033] It is understandable that by setting a steel wire rope 150 in the core rubber layer 130 inside the drive belt 100, the steel wire rope 150 is made of 7 strands of steel wire 160 twisted together, and each strand of steel wire 160 is made of 7 steel wires twisted together, thereby improving the tensile strength of the entire steel wire rope 150. Furthermore, the steel wire rope 150 is divided into six segments within the core rubber layer 130, which can more evenly distribute the tensile force on the drive belt 100, thereby making the drive belt 100 bear the force evenly and increasing the tensile strength of the drive belt 100.

[0034] In a further embodiment, the drive belt 100 of this embodiment is divided into left and right parts, namely the left half and the right half. The core rubber layer 130 inside the left half and the right half respectively has three steel wire segments, thereby improving the tensile strength of the left and right drive belts 100. The number of steel wire segments inside the two parts is the same, so that the drive belts 100 inside the left and right parts bear a portion of the tension, avoiding the tearing of the left and right parts due to uneven force when the whole drive belt 100 is in place. In addition, an upper connecting frame 210 is provided on the upper end surface of the left and right drive belts 100, which connects to the upper end of the steel wire segments. A lower connecting frame 240 is provided on the lower end surface of the left and right drive belts 100, which connects to the lower end of the steel wire segments. This allows the six steel wire segments to be fully stressed, preventing the drive belt 100 from being torn, further extending its service life and reducing the equipment maintenance cost of low-carbon mining.

[0035] Specifically, the upper connecting frame 210 has two upper pulleys rotatably mounted, and two fixing rods 230 are symmetrically arranged on the outer sides of the two upper pulleys. The two fixing rods 230 are used to connect the two ends of a whole steel wire rope 150. The lower connecting frame 240 has three lower pulleys rotatably connected, and the three lower pulleys are close to each other. For ease of description, as shown... Figure 9 As shown, the three sliding rollers are named from left to right as first sliding roller 241, second sliding roller 242, and third sliding roller 243. The lower end face of the first sliding roller 241 slides in contact with the upper end face of the shaft of the second sliding roller 242. The upper and lower end faces of the second sliding roller 242 slide in contact with the lower end face of the shaft of the first sliding roller 241 and the upper end face of the shaft of the third sliding roller 243, respectively. The upper end face of the third sliding roller 243 slides in contact with the lower end face of the shaft of the second sliding roller 242. The first sliding roller 241, second sliding roller 242, and third sliding roller 243 are arranged from top to bottom and from left to right. Similarly, for ease of description, as... Figure 2 and Figure 3As shown, the two upper pulleys are named first upper pulley 211 and second upper pulley 212 from left to right. The lower end face of the first upper pulley 211 and the upper end face of the shaft of the second upper pulley 212 are in sliding contact, while the upper end face of the second upper pulley 212 is in sliding contact with the lower end face of the shaft of the first upper pulley 211. In other words, the arrangement of the two upper pulleys on the upper connecting frame 210 is the same as the arrangement of the three lower pulleys on the lower connecting frame 240.

[0036] The method for winding a single 150mm steel wire rope is as follows: One end of a single steel wire rope 150 is fixedly connected to one of the fixed rods 230 and then wound around two upper pulleys and three lower pulleys in sequence, and finally fixed to another fixed rod 230. By winding the steel wire rope 150 around the two upper pulleys and three lower pulleys, the steel wire rope 150 can slide on the two upper pulleys and three lower pulleys, thereby balancing the tension of the steel wire rope 150.

[0037] Specifically, in this embodiment, one end of a single steel wire rope 150 is fixedly connected to a fixing rod 230 on the upper connecting frame 210, such as... Figure 3 and Figure 4 As shown, the wire rope 150 is specifically connected to the fixed rod 230 on the left side of the upper connecting frame 210. The other end of the entire wire rope 150 passes through the left side of the left half of the drive belt 100 and then wraps around the outer circumference of the first pulley 241 on the lower connecting frame 240. After wrapping around the outer circumference of the first pulley 241, the wire rope 150 passes through the left side of the right half of the drive belt 100 and exits from the upper left side of the right half of the drive belt 100. After wrapping around the outer circumference of the first pulley 211 on the upper connecting frame 210, the wire rope 150 passes through the upper end of the middle part of the left half of the drive belt 100 again and exits from the lower end of the middle part of the left half of the drive belt 100. Then it wraps around the outer circumference of the second pulley 242 on the lower connecting frame 240. After the setup is complete, the wire rope 150 is inserted into the lower end of the middle part of the right half drive belt 100 and exits from the upper end of the middle part of the right half drive belt 100. After exiting, it is wrapped around the outer circumference of the second upper pulley 212 of the upper connecting frame 210. After wrapping around the outer circumference of the second upper pulley 212, the wire rope 150 is inserted into the upper end of the right side part of the left half drive belt 100 and exits from the lower end of the right side part of the left half drive belt 100. After exiting, it is wrapped around the outer circumference of the third lower pulley 243 of the lower connecting frame 240. After wrapping, it is inserted into the bottom end of the right side part of the right half drive belt 100 and exits from the upper end of the right side part of the right half drive belt 100. One end of the wire rope 150 is finally fixed to the fixing rod 230 on the right side, thus completing the setup of the wire rope 150.

[0038] It is understandable that the aforementioned wire ropes 150, after passing through the core rubber layer 130 of the left half of the drive belt 100, are all wound around the left side of the two upper pulleys and three lower pulleys, while the wire ropes 150, after passing through the core rubber layer 130 of the right half of the drive belt 100, are all wound around the right side of the two upper pulleys and three lower pulleys. This allows the left and right drive belts 100 to move up and down independently. Through the arrangement of the wire ropes 150 and the setting of multiple upper and lower pulleys, the wire ropes 150 wound around the upper and lower pulleys can be evenly stressed. When one part of the left and right drive belts 100 is stressed differently from the other part, the wire ropes 150 will drive the upper and lower pulleys to rotate, thereby balancing the stress on the wire ropes 150 and making the overall stress on the wire ropes 150 the same. This prevents uneven stress on the wire ropes 150 from affecting the drive belts 100, ensuring stable operation of the equipment and reducing energy consumption increases due to malfunctions.

[0039] It should be noted that the outer circumferences of the rotating shafts of the two upper pulleys and three lower pulleys in this invention are all coaxial and fixedly connected to bearings 260, such as... Figure 5 As shown, the outer periphery of the bearing 260 is fixedly connected to the upper connecting frame 210 and the lower connecting frame 240 by the fixing frame 270. The setting of the bearing 260 reduces rotational friction, reduces energy loss, and further improves the energy-saving effect of low-carbon mining.

[0040] In a further embodiment, the two upper pulleys on the upper connecting frame 210 and the three lower pulleys on the lower connecting frame 240 of the present invention are all inclined, and the angle and direction of inclination are the same, such as... Figure 9As shown, the first pulley 241, the second pulley 242, and the third pulley 243 are all tilted upwards to the right, so that the steel wire ropes 150 wound around the outer periphery of the first pulley 241, the second pulley 242, and the third pulley 243 are as close as possible to the same horizontal straight line, avoiding stepped connection points. If the multiple pulleys are not tilted, the steel wire ropes 150 wound around the outer periphery of the multiple pulleys will be in a stepped state. For example, if the first pulley 241, the second pulley 242, and the third pulley 243 are arranged from top to bottom and are not tilted, then the left end of the first pulley 241, the left end of the second pulley 242, and the left end of the third pulley 243 will be distributed from top to bottom, which will result in the first pulley 241, the second pulley 242, and the third pulley 243 being distributed from top to bottom. The steel wire ropes 150 on pulleys 242 and 243 are also distributed from top to bottom. Specifically, the position where the steel wire rope 150 exits from the first pulley 241 is located at the upper left corner of the position where the steel wire rope 150 exits from the second pulley 242, and the position where the steel wire rope 150 exits from the second pulley 242 is located at the upper left corner of the position where the steel wire rope 150 exits from the third pulley 243. Furthermore, the steel wire ropes 150 at these locations are all located on the left half. If they were distributed in a stepped pattern, it would affect the drive belt 100 on the left half, causing the lower end of the drive belt 100 on the left half to be subjected to torsional force, resulting in twisting of the drive belt 100 on the left half, thus affecting the drive belt 100 on the left half. The same applies to the drive belt 100 on the right half, which will not be elaborated further here. However, when tilted, such as... Figure 9 As shown, the left ends of the first pulley 241, the second pulley 242, and the third pulley 243 are on the same horizontal straight line, which makes the end of the steel wire rope 150 that passes through the left half of the drive belt 100 also on the same horizontal straight line. This ensures that the left half of the drive belt 100 is in a flat state rather than a twisted state, thus enabling the left half of the drive belt 100 to work normally. Similarly, the right half of the drive belt 100 is the same, which will not be elaborated on here.

[0041] It should be noted that the three lower pulleys on the lower connecting frame 240 are tilted to avoid torsional forces on the lower ends of the left and right drive belts 100. Therefore, the two upper pulleys on the upper connecting frame 210 also need to be tilted, firstly to accommodate the tilt of the three lower pulleys on the lower connecting frame 240, and secondly to avoid torsional forces on the upper ends of the left and right drive belts 100. Specifically, the tilt direction of the two upper pulleys on the upper connecting frame 210 is the same as the tilt direction of the three lower pulleys on the lower connecting frame 240.

[0042] In a further embodiment, an upper connecting plate 220 is fixedly connected to the upper connecting frame 210, and the upper connecting plate 220 is connected to the sucker rod (not shown in the figure) of the tower-type pumping unit. A lower connecting plate 250 is fixedly connected to the lower connecting frame 240, and the lower connecting plate 250 is connected to a weight (not shown in the figure). The weight drives the sucker rod to move back and forth through the drive belt 100 to realize the function of pumping oil. The stable connection structure ensures that the oil pumping process is efficient and continuous, reduces energy loss, and improves the efficiency of low-carbon mining.

[0043] In a further embodiment, the aramid layer 120 in this embodiment is obtained by plasma treatment, specifically by etching the aramid and then bonding and fixing it between the upper adhesive layer 110, the core adhesive layer 130 and the lower adhesive layer 140 after active points are generated on the surface of the aramid layer 120.

[0044] Etching the aramid layer 120 using plasma treatment creates adhesive active sites on its surface, which enhances the adhesion between the aramid layer 120 and the upper adhesive layer 110, the core adhesive layer 130, and the lower adhesive layer 140. This treatment method not only improves the interlayer adhesion but also optimizes the overall performance and durability of the drive belt 100. At the same time, the plasma treatment process has low energy consumption and no wastewater or exhaust gas emissions, significantly reducing the environmental impact of the manufacturing process compared to traditional chemical treatment methods.

[0045] Plasma treatment is a technique that uses low-temperature plasma (also known as cold plasma) to treat the surface of materials. During this process, the surface of the aramid layer 120 is exposed to a plasma environment containing high-energy electrons, ions, atoms, and molecules, leading to a series of physical and chemical reactions on the surface. Plasma can remove contaminants such as oil, dust, and oxides from the surface of the aramid layer 120, while simultaneously micro-etching the surface to create a rougher surface structure. This helps increase the surface area, thereby enhancing the adhesion of subsequent adhesive layers. During plasma treatment, the molecular structure of the aramid fiber surface is disrupted or rearranged, generating new chemical groups (such as hydroxyl (-OH) and carboxyl (-COOH)) that enhance adhesion. These active groups make the aramid surface more hydrophilic, enabling it to react more effectively with other materials (such as adhesive layers). Through plasma treatment, adhesive active sites are formed on the surface of the aramid layer 120. These active sites can form stronger chemical or physical bonds with resin molecules or adhesive molecules in the upper adhesive layer 110, core adhesive layer 130, and lower adhesive layer 140, thereby improving interlayer adhesion.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
