Description

Technical Field

[0001] This invention relates to the field of tension machine technology, specifically to a tension-adjustable power cable installation tension machine for new energy applications. Background Technology

[0002] The working principle of a tension machine is to measure the tension on the material through a sensor, and then convert this tension into an electrical signal. The electrical signal is used in conjunction with the construction requirements. For more information, please refer to the relevant content mentioned in publication number CN102527776A. Essentially, it is a process of material release and take-up using a motor.

[0003] Taking power cables as an example, tension machines are needed during their construction to reduce the physical exertion of workers. It's important to note that while tension machines forcibly alter the material's release and take-up process through their rotation, the high weight of power cables leads to significant tension fluctuations due to varying distances during release and take-up. For instance, shorter release distances result in lower tension for the same power cable, while longer release distances result in higher tension. This increases the physical exertion of workers and directly impacts the power components (motor) of the tension machine, specifically increasing the workload on the transmission structure. This application proposes a solution to this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a tension-adjustable power cable installation tension machine for new energy applications. This tension machine is designed for use in the power cable installation process, where the relatively large weight of the power cable results in significant tension fluctuations during the overall cable laying process, directly impacting the workload of the internal transmission structure of the power unit.

[0005] The objective of this invention can be achieved through the following technical solution: a tension-adjustable power cable installation and erection new energy tension machine, comprising a machine cover and a cable body, wherein a transmission assembly is provided inside the machine cover, and the transmission assembly includes a large winding wheel, a force-receiving guide wheel, a cooperating gear and a driving gear; The large winding reel is arranged in a mirror-symmetrical manner on both sides of the force-bearing guide wheel. The cooperating gear is mounted on the large winding reel. The driving gear is located in the middle of the two cooperating gears and is in external meshing with the cooperating gear. A corresponding drive motor structure is provided on the outside of the driving gear. The force-receiving guide wheel is located directly below the drive gear. A related hydraulic interaction assembly is provided between the large winding reel, the force-receiving guide wheel, and the drive gear. The hydraulic interaction assembly includes a first return oil chamber located in the large winding reel, a collection oil tank located on the lower side of the force-receiving guide wheel, and a speed-changing wheel and a pressure wheel corresponding to the outside of the drive gear.

[0006] The configuration is further defined as follows: the large winding reel, the drive gear, and the cooperating gear are rotatably connected inside the machine cover, and the oil collection tank is installed at the bottom of the inside of the machine cover.

[0007] The configuration is further defined as follows: a plurality of pressure-bearing arc plates are arranged in a circular array around the center point of the large winding wheel. The pressure-bearing arc plates are slidably connected to the large winding wheel along a linear direction pointing to the center point of the large winding wheel. A first branch oil cylinder corresponding to the first return oil chamber is installed on the pressure-bearing arc plate. The first branch oil cylinder is connected to the interior of the first return oil chamber.

[0008] Further configuration: a mounting base is installed directly above the force-bearing guide wheel, and a second branch cylinder is provided between the force-bearing guide wheel and the collecting oil tank; a differential gear is rotatably mounted on the drive gear; two vertically arranged straight gear plates are provided on the mounting base along the setting direction of the two large winding wheels; the two straight gear plates are externally meshed with the differential gear; one of the straight gear plates is fixedly connected to the mounting base, and the other straight gear plate is slidably connected to the mounting base in the vertical direction.

[0009] The gear is further configured such that: the gear shift wheel is mounted on the drive gear, the differential gear is mounted on one side of the gear shift wheel, the pressure wheel is positioned between the second oil return chamber and the gear shift wheel, and the pressure wheel and the second oil return chamber are slidably connected.

[0010] The further configuration is as follows: the outer walls of the gear shift wheel and the pressure wheel that are close to each other are both wavy, and a gap is provided between the gear shift wheel and the pressure wheel that are close to each other.

[0011] Further configuration: The second return oil tank and the first return oil tank are connected to the inside of the collection tank via hoses.

[0012] The present invention has the following beneficial effects: 1. This invention is aimed at the installation process of power cables. Based on two large winding spools, it performs two actions of winding and unwinding the power cables. First, the structure of the large winding spools is improved. Essentially, it utilizes the pressure (clamping) change generated by the power cable winding on the large winding spools. According to the pressure-hydraulic conversion process, the clamping pressure of the power cable on the large winding spools is transferred to the force guide wheel. In essence, it drives the winding method of the power cable on the large winding spools and the force guide wheel to transfer the tension of the power cable. 2. Based on the above, the overall winding process is based on the rotation of the drive gear, but is interfered with by the force-bearing guide wheel, which drives the differential gear to rotate in an undirected and unpredictable manner. The purpose is to further interfere with the winding process of the power cable, thereby converting the pressure changes generated at the three locations into hydraulic pressure. On this basis, by actively changing the oil pressure in the collector tank, the workload of the overall structure is directly reduced. In essence, the force-bearing guide wheel is the key structure to withstand the tension changes in the overall structure, and the tension changes during the erection process are indirectly changed by actively changing the oil pressure in the collector tank.

Detailed Implementation

[0016] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Regarding the application of tension machines in the process of power cable laying, because power cables are relatively heavy, the overall laying process involves significant tension fluctuations, directly affecting the workload of the internal transmission structure of the power unit. The following technical solution is proposed to address this issue: Reference Figures 1-6 The tension adjustable power cable installation and erection new energy tension machine in this embodiment includes a machine cover 1 and a cable body 4. The machine cover 1 is equipped with a transmission assembly, which includes a large winding wheel 5, a force-receiving guide wheel 7, a cooperating gear 2 and a driving gear 3. The large winding reel 5 is arranged in a mirror symmetrical manner on both sides of the force-bearing guide wheel 7. The cooperating gear 2 is installed on the large winding reel 5. The driving gear 3 is located in the middle of the two cooperating gears 2 and is in external meshing with the cooperating gear 2. The driving gear 3 is equipped with a corresponding drive motor structure on its exterior. The force-receiving guide wheel 7 is located directly below the drive gear 3. A related hydraulic interaction assembly is provided between the large winding wheel 5, the force-receiving guide wheel 7, and the drive gear 3. The hydraulic interaction assembly includes a first return oil chamber 10 located in the large winding wheel 5, a collection oil tank 8 located on the lower side of the force-receiving guide wheel 7, a speed-changing wheel 14 and a pressure wheel 15 located on the outside of the drive gear 3. The large winding wheel 5, the drive gear 3, and the cooperating gear 2 are rotatably connected inside the machine cover 1. The collection oil tank 8 is installed at the bottom of the inside of the machine cover 1.

[0018] Basic principle: Figure 3 Based on this, the tension machine structure proposed in this invention is basically similar to the conventional structure, using two large winding wheels 5 as its foundation, but it requires reference to... Figure 2 Additional explanation: First, the winding method for power cables needs to be improved. Power cables need to be wound independently on the large winding wheel 5, and the winding direction can be either counterclockwise or clockwise. This part is not directly limited, but the difference lies in: The power cable located between the two large winding wheels 5 is supported by the force-bearing guide wheel 7. The driving gear 3 serves as the power source. During its rotation, the two large winding wheels 5 rotate in opposite directions. One large winding wheel 5 winds up the power cable, while the other large winding wheel 5 unwinds it. The winding direction of the power cable on the large winding wheels 5 needs to be determined according to the rotation direction of the two large winding wheels 5. This part needs to be determined according to the on-site construction parameters. It should be noted that: because power cables are heavy, and the tension they generate is proportional to the laying distance, and under normal conditions, when the power cable is completely wound on the two large winding wheels 5, the power cable located in the middle of the two large winding wheels 5 is in a taut state. However, in this embodiment, a force-bearing guide wheel 7 needs to be added in the middle of the two large winding wheels 5, so that... Figure 2 As shown, the power cable located between the two large reels 5 is in an upward-bending shape, so the force guide wheel 7 is continuously subjected to downward pressure.

[0019] Example 2: This example explains the winding process of power cables: The large winding reel 5 is provided with multiple pressure-bearing arc plates 6 arranged in a circular array around the center point of the large winding reel 5. The pressure-bearing arc plates 6 are slidably connected to the large winding reel 5 along a linear direction pointing to the center point of the large winding reel 5. A first branch oil cylinder 11 corresponding to the first return oil tank 10 is installed on the pressure-bearing arc plate 6. The first branch oil cylinder 11 is connected to the inside of the first return oil tank 10. A mounting seat 12 is installed directly above the force guide wheel 7. A second branch oil cylinder is provided between the force guide wheel 7 and the collection oil tank 8. A differential gear 9 is rotatably mounted on the drive gear 3. Two vertically arranged straight gear plates 13 are arranged on the mounting base 12 along the setting direction of the two large winding wheels 5. The two straight gear plates 13 are externally meshed with the differential gear 9. One of the straight gear plates 13 is fixedly connected to the mounting base 12, and the other straight gear plate 13 is slidably connected to the mounting base 12 in the vertical direction. The gear shift wheel 14 is mounted on the drive gear 3. The differential gear 9 is mounted on one side of the gear shift wheel 14. The pressure wheel 15 is located in the middle of the second oil return chamber 16 and the gear shift wheel 14. The pressure wheel 15 and the second oil return chamber 16 are slidably connected. The outer walls of the gear shift wheel 14 and the pressure wheel 15 that are close to each other are wavy. There is a gap between the gear shift wheel 14 and the pressure wheel 15 that are close to each other. The second oil return chamber 16 and the first oil return chamber 10 are connected to the inside of the collection tank 8 through a hose.

[0020] Solution Description: Combining Figure 3 and Figure 4And explain as follows: S1: Because the power cable needs to be wound around the large winding wheel 5 at least once, and as the installation work progresses, the power cable continues to rotate with the large winding wheel 5 as a "guide wheel structure". Due to the change in tension, the stress on one end of the power cable is greater. Specifically, the power cable continuously tightens the large winding wheel 5. Therefore, it can be directly understood that the change in tension generated on the power cable can be directly reflected on the large winding wheel 5. More specifically: the pressure-bearing arc plate 6 moves linearly in the direction pointing to the center point of the large winding wheel 5 due to the clamping process from the power cable. The first branch cylinder 11 is essentially a telescopic hydraulic rod structure. Due to the sliding action of the pressure-bearing arc plate 6, the hydraulic oil inside the first branch cylinder 11 in a local position is compressed and squeezed into the first return oil tank 10, and the hydraulic oil in the first return oil tank 10 is also squeezed into the collection oil tank 8. S2: Recombined with Figure 5 To explain, because the force guide wheel 7 is continuously subjected to the pressure changes of the power cable, the force guide wheel 7 continuously generates downward pressure. Therefore, the second branch cylinder on the lower side of the force guide wheel 7 will also squeeze the hydraulic oil inside into the collection oil tank 8. In conjunction with S1, because of the replenishment process of hydraulic oil from the first return oil tank 10, the force guide wheel 7 is subjected to an upward supporting force. S3: The force-bearing actions of the large winding wheel 5 and the force-bearing guide wheel 7 described in S1 and S2 are independent. However, during the operation of the whole device, the large winding wheel 5 and the force-bearing guide wheel 7 will have a related action. If the force-bearing guide wheel 7 is only subjected to downward pressure, it will cause the whole mounting base 12 to move downward, so that one of the straight gear plates 13 will cooperate with the differential gear 9 and drive the differential gear 9 to rotate clockwise. Furthermore, the rotation angle of the differential gear 9 is proportional to the pressure borne by the force guide wheel 7. Conversely, because the force guide wheel 7 will bear an upward supporting force, the actual rotation angle of the differential gear 9 will differ. The other straight gear plate 13 is mainly used to maintain the positional stability of the differential gear 9 during rotation. S4: Supplementary explanation based on S4: Because the two large winding spools 5 are mainly connected by the external meshing relationship between the driving gear 3 and the cooperating gear 2, and referring to... Figure 6 To explain, if the overall power cable is in a relatively stable state, it is only necessary to ensure that the drive gear 3 rotates at a constant speed. In this situation, the gear shift wheel 14 continuously passes through the pressure wheel 15. Due to the structural characteristics of the gear shift wheel 14 and the pressure wheel 15 being close to the outer wall, the pressure wheel 15 and the second return oil chamber 16 undergo multiple reciprocating motions. The pressure wheel 15 and the second return oil chamber 16 are essentially structures like telescopic cylinders. As a result, the hydraulic oil in the second return oil chamber 16 is filled into the collection oil tank 8, or the hydraulic oil in the collection oil tank 8 is also replenished into the second return oil chamber 16, and the flow process of the hydraulic oil is in a relatively balanced state. However, in reality, the tension of power cables fluctuates greatly. The structure that directly bears / induces the tension change is the drive gear 3, which causes the rotation speed of the gearbox 14 to fluctuate significantly. This directly affects the reciprocating motion of the pressure wheel 15 relative to the second return oil tank 16. It should be noted that the rotation process of the differential gear 9 does not interfere with the drive gear 3. The differential gear 9 is only related to the change in the amount of hydraulic oil in the collection oil tank 8.

[0021] Example 3: Supplementary explanation of the oil collection tank in Example 1 and Example 2: Based on the content of Embodiment 2 and Embodiment 1, it can be understood that: the tension change generated during the power cable erection process is directly reflected on the large winding wheel 5, and is concentrated in the collecting oil tank 8 through the hydraulic conversion process. In order to reduce the workload of the drive gear 3, it is necessary to coordinate with the change of the original liquid in the collecting oil tank 8 to change the direction of the rotation of the drive gear 3. Specifically, when the power cable is under high tension, its rotation is hindered. To address this, the hydraulic pressure changes in the collector oil tank 8 are directly reflected in the up-and-down movement of the mounting base 12. This is achieved by setting up an external hydraulic pressure control structure. The essence of the hydraulic pressure control structure is to monitor the hydraulic pressure changes in the collector oil tank 8 in real time and further change the internal hydraulic pressure changes, thereby changing the rotation process of the differential gear 9. Therefore, it is used to directly change the rotation action of the drive gear 3. Essentially, when the drive gear 3 is under high tension and its speed is low, it actively drives the pressure wheel 15 to move closer to the transmission wheel 14 to perform initial clamping and stabilization of the drive gear 3. The specific hydraulic pressure control parameters are not described in this invention.

[0022] In summary, the installation process of power cables utilizes two large reels to perform the winding and unwinding actions. A force-bearing guide wheel and differential gear are positioned at the midpoint between these two reels. Essentially, the system leverages the clamping force generated by the power cable winding around the reels, combined with the downward pressure exerted by the cable on the force-bearing guide wheel. This stress change is converted into hydraulic pressure. The key lies in the linear vertical movement of the force-bearing guide wheel caused by the cable winding process. This hydraulic pressure then actively controls and limits the driving gear. The purpose is to reduce the workload on the power components during power cable installation by converting stress and hydraulic force at three different locations.
