According to the power cable erecting device, a driving gear is actively controlled and limited through hydraulic pressure changes, and the purpose is that in the power cable erecting process, the workload for a power piece is reduced through the conversion process of stress and hydraulic pressure in three positions.

Description

Technical Field

[0001] The invention relates to the technical field of tension machines, and in particular to a tension-adjustable new energy tension machine for installing and erecting power cables. Background Art

[0002] The working principle of the tension machine is to measure the tension on the material through a sensor, and then convert the tension into an electrical signal. The electrical signal is used in conjunction with the construction requirements. You can refer to the relevant content mentioned in the publication number CN102527776A. Its essence is to use a motor to coordinate the material's retraction and release process.

[0003] Taking the material of power cable as an example, during its construction process, a tension machine is needed to cooperate with the construction work to reduce the physical consumption of the construction workers. It should be noted that the tension machine forcibly changes the material retraction and release process through its own rotation action. However, because the weight of materials such as power cables is relatively high, the tension fluctuations during the retraction and release process are relatively high due to the influence of distance. For example, when the pay-off distance of the same power cable is relatively short, the tension generated is relatively low; on the contrary, when the pay-off distance is relatively long, the tension generated is relatively high. On the one hand, it will increase the physical consumption of the construction workers, and on the other hand, it will directly affect the power parts (motor) in the overall tension machine, which is specifically manifested in increasing the workload of the transmission structure. This application proposes a solution to this problem. Summary of the invention

[0004] The purpose of the present invention is to provide a new energy tension machine for installing and erecting power cables with adjustable tension. The tension machine is used in the operation process of erecting power cables. Because the power cables themselves have a relatively large specific gravity, there are high tension fluctuations in the overall pay-off process, which directly affects the workload of the internal transmission structure of the power parts.

[0005] The purpose of the present invention can be achieved by the following technical solutions: 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 arranged inside the machine cover, and the transmission assembly comprises a large winding wheel, a force guide wheel, a cooperative gear and a driving gear; The large winding wheel is arranged at both sides of the force guide wheel in a mirror-symmetrical manner, the cooperative gear is installed on the large winding wheel, the driving gear is arranged in the middle of the two cooperative gears and is in an external meshing state with the cooperative gears, and a corresponding driving motor structure is arranged outside the driving gear; The force guide wheel is located directly below the driving gear, and an associated oil pressure interaction assembly is arranged between the large winding wheel, the force guide wheel and the driving gear. The oil pressure interaction assembly includes a first return oil tank arranged in the large winding wheel, a collecting oil tank arranged on the lower side of the force guide wheel, and a speed change wheel and a pressure wheel corresponding to the outside of the driving gear.

[0006] It is further configured as follows: the large winding wheel, the driving gear, and the cooperative gear are rotatably connected inside the hood, and the collecting oil tank is installed at the bottom end position inside the hood.

[0007] It is further configured as follows: a plurality of pressure arc plates arranged in a circular array along the center point of the large winding wheel are arranged on the outside of the large winding wheel, the pressure arc plate is slidingly connected to the large winding wheel along the linear direction pointing to the center point of the large winding wheel, and a first branch oil cylinder corresponding to the first oil return tank is installed on the pressure arc plate, and the first branch oil cylinder is connected to the inside of the first oil return tank.

[0008] It is further configured as follows: a mounting seat is installed directly above the force guide wheel, and a second branch oil cylinder is provided between the force guide wheel and the collecting oil tank, a differential gear is rotatably installed on the driving gear, and two vertically arranged straight gear plates are provided on the mounting seat along the setting direction of the two large winding wheels, the two straight gear plates and the differential gear are in an external meshing state, and one of the straight gear plates is fixedly connected to the mounting seat, and the other straight gear plate is slidably connected to the mounting seat along the vertical direction.

[0009] It is further configured as follows: the speed change wheel is installed on the driving gear, a second oil return tank is installed on a side position of the differential gear corresponding to the speed change wheel, the pressure wheel is arranged in the middle position between the second oil return tank and the speed change wheel, and the pressure wheel and the second oil return tank are slidably connected.

[0010] It is further configured as follows: the outer walls of the speed-changing wheel and the pressure wheel on the side close to each other are both wavy, and a gap is provided between the positions of the speed-changing wheel and the pressure wheel on the side close to each other.

[0011] It is further configured as follows: the second oil return tank and the first oil return tank are connected to the inside of the collecting oil tank through a hose.

[0012] The present invention has the following beneficial effects: 1. The present invention is aimed at the erection process of power cables. Based on two large winding wheels, the present invention performs two actions of winding and releasing the power cables. First, the structure of the large winding wheel is improved. Its essence is to utilize the pressure (tightening) change generated by the winding of the power cable on the large winding wheel, and according to the pressure-hydraulic conversion process, transfer the tightening pressure of the power cable on the large winding wheel to the force guide wheel. Its essence is to drive the winding method of the power cable on the large winding wheel and the force guide wheel to transfer the tension process of the power cable; 2. Based on the above content, the overall winding process is based on the rotation of the driving gear, but is subject to the interference process from the force guide wheel, thereby driving the differential gear therein to perform an undirected and unfixed speed rotation process. Its purpose is to further interfere with the winding process of the power cable, thereby converting the pressure changes generated in the three positions into liquid pressure. On this basis, by actively changing the oil pressure changes in the collecting oil tank, the workload in the overall structure is directly reduced. Its essence is that the overall structure uses the force guide wheel as the key structure to withstand tension changes, and indirectly changes the tension changes during the erection process by actively changing the oil pressure in the collecting oil tank.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1: In view of the application of tension machines in the process of laying power cables, since the power cables themselves have a relatively large specific gravity, there are high tension fluctuations in the overall pay-off process, which directly affects the workload of the internal transmission structure of the power parts. The following technical solutions are proposed: Reference Figures 1 to 6 In this embodiment, a tension-adjustable power cable installation and erection new energy tension machine includes a machine cover 1 and a cable body 4. A transmission assembly is arranged inside the machine cover 1. The transmission assembly includes a large winding wheel 5, a force guide wheel 7, a cooperative gear 2 and a driving gear 3; The large winding wheel 5 is arranged at both sides of the force guide wheel 7 in a mirror-symmetrical manner, the cooperative gear 2 is installed on the large winding wheel 5, the driving gear 3 is arranged in the middle of the two cooperative gears 2 and is in an external meshing state with the cooperative gear 2, and the driving gear 3 is provided with a corresponding driving motor structure outside; The force guide wheel 7 is located directly below the driving gear 3. An associated oil pressure interaction assembly is arranged between the large winding wheel 5, the force guide wheel 7 and the driving gear 3. The oil pressure interaction assembly includes a first return oil tank 10 arranged in the large winding wheel 5, an oil collecting tank 8 arranged on the lower side of the force guide wheel 7, and a speed change wheel 14 and a pressure wheel 15 corresponding to the outside of the driving gear 3. The large winding wheel 5, the driving gear 3, and the cooperative gear 2 are rotatably connected inside the hood 1, and the oil collecting tank 8 is installed at the bottom end position inside the hood 1.

[0018] Basic principle: Figure 3 Based on, the tension machine structure proposed by the present invention is basically similar to the conventional structure, based on two large winding wheels 5, but it is necessary to refer to Figure 2 Supplementary explanation: First, the winding method of the power cable is improved. The power cable needs to be independently wound on the large winding wheel 5. The winding direction includes counterclockwise or clockwise. This part is not directly limited. The difference is: The power cable located in the middle of the two large winding wheels 5 will be supported by the force guide wheel 7, so that the driving gear 3 is used as the power source. During the rotation process, the two large winding wheels 5 maintain a reverse rotation process, so that one of the large winding wheels 5 reels the power cable, while the other large winding wheel 5 unwinds the power cable. For this, the winding direction of the power cable on the large winding wheel 5 needs to be limited according to the rotation direction of the two large winding wheels 5, and this part needs to be determined according to the on-site construction parameters; It should be noted that: because the power cable is heavy, and the tension generated by it is proportional to the laying distance, and in a normal state, 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 straight state, but in this embodiment, it is necessary to add a force guide wheel 7 in the middle of the two large winding wheels 5, so as to Figure 2 As shown, the power cable located between the two large winding wheels 5 is in an upwardly bent shape, so that the force guide wheel 7 is continuously subjected to downward pressure.

[0019] Embodiment 2: This embodiment explains the winding process of the power cable: A plurality of pressure arc plates 6 are arranged in a circular array along the center point of the large winding wheel 5 on the outside of the large winding wheel 5. The pressure arc plates 6 are slidably connected to the large winding wheel 5 along the linear direction pointing to the center point of the large winding wheel 5, and a first branch oil cylinder 11 corresponding to the first oil return tank 10 is installed on the pressure arc plate 6. The first branch oil cylinder 11 is connected to the inside of the first oil return tank 10. A mounting seat 12 is installed directly above the force guide wheel 7, and a second branch oil cylinder is arranged between the force guide wheel 7 and the collecting oil tank 8; A differential gear 9 is rotatably mounted on the driving gear 3, and two straight gear plates 13 are vertically arranged on the mounting seat 12 along the setting direction of the two large winding wheels 5. The two straight gear plates 13 are in an external meshing state with the differential gear 9, and one of the straight gear plates 13 is fixedly connected to the mounting seat 12, and the other straight gear plate 13 is slidably connected to the mounting seat 12 along the vertical direction; The speed wheel 14 is installed on the driving gear 3, and a second oil return tank 16 is installed on the side of the differential gear 9 corresponding to the speed wheel 14. The pressure wheel 15 is arranged in the middle position between the second oil return tank 16 and the speed wheel 14, and the pressure wheel 15 and the second oil return tank 16 are slidably connected. The outer walls of the speed wheel 14 and the pressure wheel 15 on the side close to each other are wavy, and a gap is arranged between the positions on the side close to each other of the speed wheel 14 and the pressure wheel 15. The second oil return tank 16 and the first oil return tank 10 are connected to the inside of the collecting oil tank 8 through a hose.

[0020] Solution Description: Combined Figure 3 and Figure 4, and explain as follows: S1: Because the power cable needs to be wound around the large winding wheel 5 for at least one circle, and during the installation operation, the power cable continuously rotates with the large winding wheel 5 as a "guide wheel structure", and the stress on one end of the power cable is greater due to the change in tension, which is specifically manifested as: the power cable continuously tightens the large winding wheel 5, so 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 compressed arc plate 6 is subjected to the tightening process from the power cable and moves linearly in the direction pointing to the center point of the large winding wheel 5, and the first branch oil cylinder 11 is essentially a telescopic oil rod structure. The sliding action of the compressed arc plate 6 causes the hydraulic oil inside the first branch oil cylinder 11 in the local position to be 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 collecting oil tank 8; S2: Combined with Figure 5 To explain, because the force guide wheel 7 is continuously subjected to the pressure change of the power cable, the force guide wheel 7 continuously generates downward pressure, so the second branch oil cylinder corresponding to the lower side of the force guide wheel 7 will also squeeze the hydraulic oil inside into the collecting oil tank 8. In conjunction with S1, because of the replenishment process of the 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 performed independently. However, during the operation of the overall device, the large winding wheel 5 and the force-bearing guide wheel 7 will have associated actions. If the force-bearing guide wheel 7 is only subjected to downward pressure, the overall mounting seat 12 will move downward, so that one of the straight gear plates 13 cooperates with the differential gear 9 and drives the differential gear 9 to rotate clockwise; And 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 the upward supporting force, the actual rotation angle of the differential gear 9 is different. The other straight gear plate 13 is mainly used to maintain the position stability of the differential gear 9 during the rotation action. S4: Supplementary explanation based on the content of S4: Because the two large winding wheels 5 are mainly meshed with the driving gear 3 and the cooperative gear 2, and refer to Figure 6 To illustrate, if the entire power cable is in a relatively stable state, it is only necessary to ensure that the driving gear 3 rotates at a uniform speed; In this case, the speed-changing wheel 14 continuously passes the pressure wheel 15. Because the speed-changing wheel 14 and the pressure wheel 15 are close to the outer wall, the pressure wheel 15 and the second oil return tank 16 undergo multiple reciprocating movements. The pressure wheel 15 and the second oil return tank 16 are essentially structures such as telescopic cylinders. Thus, the hydraulic oil in the second oil return tank 16 is filled into the manifold tank 8, or the hydraulic oil in the manifold tank 8 is also replenished into the second oil return tank 16, and the flow process of the hydraulic oil is in a relatively balanced state. However, in actual situations, the tension of the power cable fluctuates greatly, and the structure that directly bears / sensed the tension change is the driving gear 3, so that the rotation speed of the speed change wheel 14 fluctuates significantly, which directly affects the reciprocating motion of the pressure wheel 15 relative to the second oil return tank 16. It should be briefly explained that the rotation process of the differential gear 9 does not interfere with the driving gear 3, and the differential gear 9 is only related to the change in the amount of hydraulic oil in the collecting tank 8.

[0021] Embodiment 3: Supplementary explanation of the collecting oil tank in Embodiment 1 and Embodiment 2 is provided as follows: Based on the contents of the second embodiment and the first embodiment, it can be understood that: the tension change generated during the installation of the power cable is directly reflected on the large winding wheel 5, and is concentrated in the collecting oil tank 8 through the hydraulic conversion process, and in order to reduce the workload of the driving gear 3, it is necessary to cooperate with the change of the stock liquid in the collecting oil tank 8 to change the direction of the rotation of the driving gear 3; Specifically, when the power cable is subjected to a large tension, its rotation process is hindered. For this purpose, the hydraulic pressure changes in the collecting oil tank 8 need to be directly reflected in the up and down movement process of the mounting seat 12. Its essence is to set an oil pressure control structure on the outside. The essence of the oil pressure control structure is to monitor the oil pressure changes in the collecting oil tank 8 in real time, and further change the oil pressure changes inside it, thereby changing the rotation process of the differential gear 9, so it is used to directly change the rotation action of the driving gear 3. Its essence is that when the driving gear 3 has a low speed due to the large tension it bears, it actively drives the pressure wheel 15 to approach the speed wheel 14, which is used to initially clamp and stabilize the driving gear 3. The specific oil pressure control parameters are not introduced in the present invention.

[0022] In summary: in the process of installing the power cable, two large winding wheels are used as the basis to perform the two actions of reeling in and unreeling the line, and associated force guide wheels and differential gears are arranged in the middle position of the two large winding wheels. Its essence is based on the tightening force generated by the power cable winding on the large winding wheels, combined with the downward pressure generated by the power cable on the force guide wheel, and the above stress changes are converted into hydraulic changes. The key is that the force guide wheel is subjected to the linear movement process in the vertical direction during the winding process of the power cable, thereby actively controlling and limiting the driving gear therein through hydraulic changes. Its purpose is: in the process of installing the power cable, through the conversion process of stress and hydraulic pressure in three positions, the workload of the power parts can be reduced.
