Description
TECHNICAL FIELD
[0001] The present application relates to the power industry, the high-voltage cable laying technology field, and in particular to an efficient modular cable non-destructive laying system, a control system and a construction method. BACKGROUND
[0002] The traditional cable laying system mainly relies on manual laying experience, although professional tools are used, but a large amount of manpower is needed to complete the laying of the cable. However, there are the following defects in the manual laying process: ① In the existing cable laying process, since the manual laying of the cable mostly relies on experience, the laying precision is poor, and at the same time, the laid cable needs to be lifted and placed in position, which is time-consuming and laborious. ② During the laying process of the cable, the stress condition of the cable cannot be monitored in real time, and the whole laying process is a black box operation, which is prone to problems such as excessive local stress and excessive tension during the laying process. If the stress of the cable exceeds the standard value, it cannot be automatically warned, resulting in damage to the cable and equipment. ③ In the existing manual cable laying process, when the cable needs to be laid in a serpentine shape, it is often necessary to cooperate with an electric hoist to lift the local part and naturally hang the other end in a form of a serpentine shape, which on the one hand leads to poor precision and large error of the laid serpentine shape, and on the other hand, the outer wall of the cable is pressed during the lifting and bending process, which is prone to cause local wear and even damage of the cable. The whole process is time-consuming and laborious. ④ In the existing technology, when the cable needs to be laid, multiple device components need to be installed along the whole laying path, and a temporary system needs to be built, which has the problems of large error, complicated process, and the risk of increased damage to the cable caused by the mismatch between the speed, traction force and speed of the conveying device, and the inability of the conveying device to maintain the same speed. ⑤ In the existing cable laying process, due to the complex conditions of the site environment or the terrain conditions, the cable needs to be laid in a slanting manner, which produces a slanting horizontal angle, such as upward conveying and downward conveying. When the traditional lateral conveying device encounters such a situation, it has the problems of being difficult to install and fix, and the cable is not parallel to the conveying device, which is prone to cause problems such as deviation of the clamping position and upward bending at the head and tail of the conveying device, resulting in different conveying friction forces at the head and tail and the middle section of the cable, which leads to speed difference and causes the conveying device to idle or the cable to be unevenly stressed and the insulation skin to be worn.
[0003] It can be seen that manual cable laying has obvious defects in safety, economy, convenience and wide applicability. There is a lack of a device system for quickly laying cables, and a lack of a one-time forming laying system and a construction method. SUMMARY
[0004] In order to solve the defects and deficiencies of the prior art, the inventor has developed and designed a high-efficiency modular cable lossless laying system, a control system and a construction method, which can quickly build a laying path and related equipment through modular equipment before laying, can monitor, adjust and coordinate unified control of the parameters of each laying link, realizes rapid, safe and lossless laying and monitoring of the cable, realizes equal-height, equal-speed and one-time snake formation laying operation, and greatly improves the operation convenience and safety.
[0005] In the application, the active pay-off stand provides power output, can adjust the cable conveying speed according to the setting, can match the speed requirement in the cable advancing process, realizes equal-speed conveying, and the cable output from the active pay-off stand is sequentially subjected to continuous tension detection and speed measurement, so as to ensure that the cable is not damaged in the laying process. The tension control refers to the ability to continuously control the tension of the raw material during conveying on the equipment. This control must be effective for any operating speed of the machine, including acceleration, deceleration and constant speed of the machine. Even in the case of emergency stop, the ability to ensure that the slitting object is not damaged can protect the cable. The conveying device in the system has a power source, and through the operation of the double belts at the same speed and in the same direction, the elastic components can clamp the cable to provide equal-speed power output. In this process, the spacing of the conveying device has a hand adjustment and self-adaptive dual function, which can meet the arrangement of various common cables of different thicknesses, and can clamp the cable and provide power conveying under the pressure that the cable can withstand. In this process, the conveying device can detect the lateral pressure and conveying speed of the cable, realize the state monitoring of the cable conveying, and at the same time, the conveying device is provided with a photoelectric sensor and a micro-motion mechanical sensor, which can ensure that the cable is synchronized to the position before starting when the cable reaches the conveying device, so as to realize the equal-speed synchronous transmission of the cable. The conveying device without detecting the signal remains silent and waits. The modular equipment structure makes the installation and arrangement of each device simple and convenient. The modular structure of the conveying device reduces the structure of the conveying device, so that it can be stably placed and fixed in horizontal and vertical ways, can meet the left and right lateral clamping conveying and the up and down vertical clamping conveying of the cable, can be selected according to the on-site laying path, and can avoid the possibility of conveying damage of the cable caused by height difference. The omnidirectional conveyor in the system is pre-installed according to the required snake laying path. The master control module can calculate the distance required by the snake according to the actual conditions of the cable to be laid, and then calculate the opening and closing angle between the double adjusting arms of the omnidirectional conveyor. After the cable enters the omnidirectional conveyor, it can pass through the angle structure between the three rollers, so that the passing cable forms a snake shape, completes the laying method of conveying and bending at the same time, realizes the one-time laying method of the cable, and the whole laying process is equal-height, equal-speed and one-time bending according to the predetermined snake bending degree, one-time laying and forming. The cable is conveyed at a linear speed, has high laying precision and good effect, and can also realize lossless laying.
[0006] The application provides a high-efficiency modular cable nondestructive laying system, a control system and a construction method, and can quickly build a complete laying system according to a laying environment and design requirements through modular equipment, realizes whole-process monitoring and control of cable lateral pressure, tension and laying speed of a cable in cable laying through optical, electrical and mechanical sensing control of each conveying device, cooperated data acquisition and processing of traction, pressure and speed, cooperated all-direction conveying machines capable of accurately controlling cable bending through control of the included angle change between two mutually hinged bending arms through telescopic mechanisms, and can complete cable laying and laying at one time, effectively simplifies construction steps, greatly improves construction efficiency and saves time, and solves the problem that the cable may be damaged in the process of artificial serpentine bending and lifting onto a support in the previous high-voltage power cable laying and laying method. The system realizes nondestructive protection of the cable in multiple links of high-voltage cable laying, sets and real-time samples, records, monitors and controls speed, lateral pressure, tension and cable bending diameter and other parameters of each device in the laying process, so as to realize fast, safe and nondestructive laying of the cable and process data recording, and can meet the operation of cable design installation fixed position, high one-time serpentine bending forming and laying. Due to the addition of the flexible self-adaptive clamping device and the guiding traction device of the conveying equipment, the problem that the original conveying equipment needs to be manually clamped according to the position of the cable front end, the system needs to be started and stopped multiple times is solved. The system improves operation convenience and safety, solves the problems in the existing laying method, such as complicated laying process, easy damage to the cable, large manual input, difficult management in the laying process and inability to collect process data, and has broad market demand and promotion prospect.
[0007] (2) This cable laying system features one-time, non-destructive laying. From the starting point of cable transport, the active cable laying frame has its own power output, reducing the pulling force of the conveying device and traction machine on the cable, and evenly distributing the laying force. This avoids cable damage caused by localized tension concentration or excessive tension. In addition, in areas requiring serpentine laying, an omnidirectional conveyor with power output is used, utilizing the central active roller to provide power at the point of greatest cable bending. This reduces stress concentration and friction at the bending points, thereby minimizing damage. The probability of injury is reduced; at the same time, in conjunction with a system where each module is individually controllable and the whole system is monitored, the pressure information during the conveying process of the conveying device, as well as the tension information and speed information during the traction process, are all monitored. It can detect any abnormality in any module in a timely manner and control the entire system to shut down for protection. The system's equal height, equal speed, and one-time bending deployment avoid damage caused by secondary handling and secondary fixing of cables. The system can complete the laying in one go, and can quickly fix, safely and without damage to complete the entire deployment process, truly achieving global non-destructive deployment.
[0008] (3) The conveying device of this system has the function of multi-sensor detection. Through the combination of photoelectric sensors and mechanical sensors, it can determine that the cable is in place before starting the conveying device, so as to realize synchronous and constant speed conveying and avoid unnecessary friction damage to the cable. At the same time, the conveying device has the function of adjustable spacing, which can adapt to meet the conveying of cables of various thicknesses and sizes. It can also acquire data on the lateral pressure of the cable, realize the monitoring of the cable speed and lateral pressure. If the lateral pressure is too high, an alarm and shutdown protection will be issued. It can also be controlled by the overall control module to perform global adaptive control of the conveying speed, achieve constant speed conveying, and further improve the protection of the cable.
[0009] (4) The modular structure of the conveying device reduces the weight of the conveying device, allowing it to be stably placed and fixed in both horizontal and vertical directions. It can meet the requirements of lateral clamping and conveying of cables and vertical clamping and conveying of cables. It can be selected according to the on-site delivery path to avoid the possibility of cable damage due to elevation differences. Lateral clamping conveying is used on horizontal delivery paths. Vertical clamping conveying is used on delivery paths with elevation differences, or when the cable is inclined upward or downward. The horizontal or vertical placement of the left and right conveyor belts can be combined and used to effectively meet more complex and varied delivery environments. It effectively prevents problems such as unstable clamping, idling, and uneven speed in traditional conveying devices when the cable is in an inclined delivery section with elevation differences, thus improving the delivery quality.
[0010] (5) The omnidirectional conveyor of the system calculates the corresponding optimal serpentine laying parameters according to the information of the on-site arrangement conditions and cable parameters, converts the angle data required to be opened between the two bending arms of the bending laying machine into the angle data between the two mutually hinged bending arms, controls the angle change between the two mutually hinged bending arms through the telescopic mechanism, adjusts the amplitude and distance of cable bending, completes the serpentine laying at one time, and has the characteristics of high precision, good laying effect and no damage to the bending.

[0041] To make the objectives, technical solutions and advantages of the present application clearer and more comprehensible, the present application will be further described in detail below with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.
[0042] Example 1: A high-efficiency modular cable lossless laying system, the main modules include equipment:
[0043] The active pay-off stand 1 has an adjustable power pay-off function, which can actively adjust the speed of the cable on the line disc. The large pay-off disc outputs the force to the line disc smoothly through four 1.5KW motors using a reduction device. The four motors are in two groups, and the width of the four motors can be adjusted according to the size of the pay-off disc. One rectifier module and two inverter modules drive four motors to achieve uniform speed. The four motors are started and stopped together, and the centralized control of forward and reverse rotation is realized. The output cable first passes through the tension detection control device to ensure that the cable is not damaged during laying. Tension control refers to the ability to control the tension of the material during conveying on the equipment. This control must be effective for any operating speed of the machine, including acceleration, deceleration and constant speed of the machine. Even in the case of emergency stop, it should have the ability to ensure that the slitting object is not damaged, which can well protect the cable;
[0044] The tension speed detection device 2 detects the speed of the output cable to obtain the conveying speed of the cable. Generally, an encoder tension speed detection device 2 can be selected and connected to the total control module through wired or wireless communication to transmit the conveying speed information to the total control module;
[0045] Several support frames 3 are used to support the fixed conveying device 4, the omnidirectional conveyor 5, the conveying roller, keep the process of cable laying at the same height as the designed installation position, and provide support for the cable during the conveying process; that is, the support frame is arranged, one part is provided every several meters, and the support function is provided. The conventional arrangement is to cooperate with one or two unpowered conveying rollers. The support frame 3 is installed at the necessary point and distance, and the conveying device 4 is installed to provide active power output to the cable, so that the cable force of each link part is uniform and the speed is the same. After the laying is completed, the support frame and the conveying equipment are removed, and the cable can be fixed and installed, thereby saving the process of moving the cable to the installation position after laying the cable on the non-installation plane in the original method.
[0046] The conveying device 4 has power and can adaptively clamp the cable within a predetermined range and ensure that the clamping force borne by the cable is within a specified range. The control system drives all conveying equipment to convey the cable at a constant speed, and optical, electrical or mechanical conveying sensors are installed to detect the relative position of the cable and the conveying equipment and obtain the lateral pressure data of the cable during the bending and clamping process. The conveying device 4 provides power to the cable along the laying path, and several conveying devices 4 are arranged along the laying path to achieve overall constant-speed laying, thereby reducing the traction requirement of the traction machine 6, uniformly distributing the cable conveying requirement for conveying force, and ensuring that the cable force of each part is uniform. This avoids the occurrence of local overload or excessive traction pulling. At the same time, the conveying device 4 is provided with a conveying sensor to detect the running state of the single conveying device 4, the lateral pressure data of the cable, and the conveying speed data of the cable, and can feed back to the total control module and receive the control instructions of the total control module to stop, start, adjust the speed, etc.

During the process of cable laying, the cable laying needs and related regulations require laying in a serpentine manner, or turning conveying is required. The turning or serpentine area is prone to stress concentration. The omnidirectional conveyor 5 is arranged to realize guiding through the vertically arranged rollers to adjust the turning or serpentine laying path of the cable.
[0048] The traction machine 6 is a traction guide angle mill arranged at the cable end to guide and pull the cable forward. The traction machine 6 mainly plays a guiding role, and through the arrangement of the active pay-off stand 1 and the conveying device 4, the traction machine 6 at the cable end only needs to guide.

For the bending point with high stress concentration, the real-time state supervision effect is realized.

[0073] Example 4: as Figures 20 to 24As shown, on the basis of each of the above embodiments, a cable laying active pay-off frame self-adjusting control device 7 is further installed between the cable active pay-off frame and the conveying device, which comprises a portal frame composed of vertical support slide rods 71 and a horizontal rod 72, a wire displacement sensor 73 is installed on the horizontal rod 72, the wire displacement sensor 73 is connected to a wire passer 74, the wire passer 74 is installed between the two vertical support slide rods 71 in a free lifting and sliding manner; the wire displacement sensor 73 is connected to a master control module, the master control module is connected to the active pay-off frame, and the pay-off rotating speed of the active pay-off frame can be controlled according to the information fed back by the wire displacement sensor 73. In actual use, the portal frame serves as a bracket structure for installing the wire passer 74. In the present embodiment, the wire passer 74 can be selected to have a device with a speed sensor or a tension sensor installed, or can only be composed of a frame 741 with four slide rollers 742 installed on the inner side surface, one horizontal rod 75 is installed on each of the left and right sides of the frame 741, the other end of the horizontal rod 75 is provided with a sliding sleeve 76, and the sliding sleeve 76 is installed on the vertical support slide rod 71; the frame 741 can adaptively lift and slide according to the real-time height position of the cable; and the wire displacement sensor 73 is connected above the frame 741. That is, the cable passes through the frame 741, the frame 741 is actually hung on the cable, the sliding sleeve 76 and the horizontal rod 75 limit the position of the cable and make it only displace in the longitudinal direction, so when the height of the cable changes, the sliding sleeve 76 lifts along the vertical support slide rod 71, and the lifting degree of the frame 741 is monitored by the wire displacement sensor 73, which is a slide block type displacement sensor vertically installed on the horizontal rod 72 of the portal frame, and the measurable stroke length range of the slide block type displacement sensor is not less than the lifting range of the wire passer 74; the wire displacement sensor 73 transmits real-time data to the master control module, after receiving the real-time height position information of the wire passer 74 sent by the wire displacement sensor 73, the master control module performs a conventional threshold judgment operation, when the height position information exceeds the threshold, the master control module can control the active pay-off frame to increase or decrease the pay-off rotating speed until the height position information is within the threshold. Therefore, when the wire displacement sensor 73 senses that the height of the cable is in the “high position”, it indicates that the cable in this area is too straight or even tight, which reflects that the conveying rotating speed of the cable is greater than the output rotating speed of the active pay-off frame, then the master control module controls the active pay-off frame to increase the laying rotating speed, so as to avoid the occurrence of tightness and pulling. When the height of the cable is detected to decrease by more than the lower limit threshold, it indicates that the cable has accumulated and sagged, and the output rotating speed of the active pay-off frame is greater than the conveying rotating speed of the conveyor, then the master control module controls the output rotating speed of the active pay-off frame to decrease until the height of the cable returns to the threshold range.The control terminal automatically adjusts the rotating speed of the active pay-off rack, so as to adapt the rotating speed of the whole cable delivery and pay-off system, and keep the rotating speed in a relatively stable stage, so as to realize intelligent and automatic control of the rotating speed of the cable pay-off process, protect the safety and stability of the cable in the delivery and pay-off process, and enhance the control precision of the whole system and improve the precision of the cable pay-off process.

Such a case considers that the cable may be transversely displaced in the left and right directions during the output from the active pay-off rack, that is, the displacement of the cable in the up-down and left-right directions is not limited, and the pressure between the cable and the cable pass-through device 74 can be reduced; when necessary, the surface of the sliding roller 742 is provided with a rubber pad, so as to further reduce the pressure and wear on the surface of the cable.
[0075] Preferably, the control terminal acquires the height data of the cable in the interval between the active pay-off rack and the first delivery device in real time and sends the data to the general control module.
[0076] The height data of the cable is acquired by the wire displacement sensor 73,
[0077] After receiving the real-time height position information of the cable sent by the wire displacement sensor 73, it is judged whether the information is in the threshold interval; when the height position information of the cable exceeds the upper limit or lower limit of the threshold, the rotating speed of the active pay-off rack is increased or decreased until the height position information is in the threshold again.
[0078] The area between the cable active pay-off rack and the first cable conveyor can reflect the speed difference between the cable active pay-off rack and the cable conveyor, when the cable in the area is too straight or even tight, it reflects that the conveying speed of the cable is greater than the output rotating speed of the active pay-off rack, which may cause the pulling damage of the cable; when the cable in the area is accumulated and droops, or even contacts the ground, it shows that the output rotating speed of the active pay-off rack is greater than the conveying speed of the conveyor, after the phenomenon occurs in the prior art, manual adjustment is needed, but manual observation is needed at all times, and the adjustment operation is relatively cumbersome, and it is not easy to control and adjust, the embodiment can obtain the current cable state signal data in the area by using the line displacement sensor 73 to judge the cable height degree in the area, and feed back to the control end, and automatically adjust the rotating speed of the active pay-off rack by the control end, so as to adapt the speed of the whole conveying and laying cable system, and keep the speed in a relatively stable stage, so as to achieve the intelligent and automatic control of the cable laying process, protect the safety and stability of the cable in the laying and conveying process, and enhance the control precision of the whole system and improve the accuracy of the cable laying process.
