Description

Technical Field

[0001] The invention relates to the technical field of vertical lifting of large-section cables for high-rise buildings, and in particular to a synchronous control method for vertically lifting large-section cables for high-rise buildings. Background Art

[0002] The three vertical cable laying technologies successfully applied in domestic high-rise buildings are wire rope traction and lifting laying technology, damping buffer laying technology, and vertical cable laying technology. Among them, the wire rope traction and lifting laying technology sets a winch on the upper floor of the vertical cable laying section, and uses slings, clamps, etc. to fix the cable sections to the wire rope. The winch lifts the cable through the auxiliary wire rope. During the vertical lifting process of the cable, the wire rope is mainly stressed. After the cable is laid in place, the slings, clamps and clamps are removed in turn.

[0003] The wire rope traction and lifting laying technology requires little space in the shaft, and a winch is used to provide traction. The cable is clamped on the wire rope in sections, which solves the problem of cable deformation or damage caused by traction force and cable weight exceeding the cable tensile capacity. The wire rope traction method is the most widely used vertical laying technology, with flexible construction organization and easy access to traction equipment. However, cable traction mainly uses wire mesh or cable clamps as traction points for traction. The allowable traction force for large-section cables is relatively small, and it is necessary to increase the main lifting wire rope and wire mesh or cable clamp. Since the wire rope and wire mesh or cable clamp need to be added during the cable traction process, the quality of the wire mesh or cable clamp and the quality of the construction personnel are relatively high. The cable also needs to be switched and lifted twice at the highest traction point in the electrical shaft. The entire cable vertical lifting process is relatively complicated, and the wire mesh or cable clamp is not fixed in place and it is easy to cause damage to the cable outer sheath. Therefore, how to solve or improve the excessive lateral pressure that the cable bears when it is directly pulled and laid through the cable turning rollers after vertical lifting in the electrical shaft to the high-rise horizontal laying channel has become a technical problem that needs to be urgently solved by technicians in this field. Summary of the Invention

[0004] The purpose of the present invention is to provide a synchronous control method for vertically lifting large-section cables in high-rise buildings, which effectively suppresses or to a certain extent improves the technical problem of excessive lateral pressure on the cables when they are directly pulled and laid through cable turning rollers to high-rise horizontal laying channels after vertical lifting in the electrical shaft.

[0005] The embodiment of the present application is implemented as follows: The embodiment of the present application provides a synchronous control method for vertically lifting a large-section cable in a high-rise building, the control method comprising:

[0006] S1. Calculate the parameters of large-section cables and formulate vertical lifting plans, process control procedures, and safety monitoring measures;

[0007] S2. Install the cable traction mechanism, cable and wire rope rollers, and set up the auxiliary wire rope segments and cable outer sheath segment multi-point connection buffer sections;

[0008] S3. Cable traction and laying;

[0009] S4. Process control of cable traction and laying.

[0010] In some embodiments, the cable pulling and laying includes:

[0011] Step 1. Before laying the cables horizontally on the ground, install cable pulling heads and cable anti-twist devices on the ends of the large-section cables and test the video and safety monitoring mechanisms to ensure they are functioning properly. Operators will then guide and pull the large-section cables on the ground using a cable conveyor. The cables will be transported through auxiliary steel rope lashing buffer sections and semi-circular laying channels, and then stopped at the bottom of the electrical shaft.

[0012] Step 2. The cable traction mechanism pulls the large-section cable in reverse order, guiding its traction wire rope through the vertical guide rollers of each cable layer to the bottom of the electrical shaft. After tightening and securing all the traction wire ropes of the electric winches on the middle and lower layers except the traction wire rope of the high-layer electric winch, the traction wire rope of the high-layer electric winch is connected to the cable traction head, the cable anti-twist device, the tension sensor on the wire rope, the wireless information transmission module and its protective cover. The initial value of the traction distance sensor of the high-layer electric winch should be set to 0, and the stop value should be set to a value less than the traction length allowed by the high-layer electric winch.

[0013] Step 3. The cable conveyor in the horizontal channel is started first. After a certain margin is reserved in the semicircular laying buffer section, the high-rise electric winch begins to pull the large-section cable vertically along the electrical shaft until the pulling distance sensor of the high-rise electric winch reaches the set stop value, at which point the high-rise electric winch stops. The starting sequence control of the cable pulling mechanism can adopt a time control mode or a distance control mode determined by the pulling distance sensor. The specific setting is made by authorized personnel through the handheld mobile terminal management module or the computer management module based on actual site conditions.

[0014] Step 4. In the buffer section where the auxiliary steel wire rope is connected to the cable outer sheath, a tying mechanism is used to quickly connect the auxiliary steel wire rope to the cable outer sheath. The entire tying work can be completed in multiple steps. After the first section of the auxiliary steel wire rope is connected to the cable outer sheath, the steel wire rope pulling head of the middle-level electric winch is connected to the auxiliary steel wire rope pulling end through the cable anti-twist device. At the same time, a cable tension sensor and a wireless information transmission module and their protective covers are installed on the cables at the traction sections of the two electric winches above the auxiliary steel wire rope. The order of cable traction is the horizontal section cable conveyor, the middle-level electric winch, and the high-level electric winch.

[0015] Step 5. After the vertical lifting of the first section of the auxiliary steel wire rope and the cable outer sheath connection section is completed, stop the cable pulling and start the second section of the auxiliary steel wire rope and the cable outer sheath connection section in the auxiliary steel wire rope and the cable outer sheath connection buffer section until the designed auxiliary steel wire rope and cable outer sheath connection section is completed;

[0016] Step 6. When the length of the traction cable section allowed by the middle-level electric winch reaches the limit value of the traction distance sensor, the traction machinery stops running, and the auxiliary steel wire rope within the traction section allowed by the lower electric winch is connected to the cable outer sheath and the large-section cable is laid within the traction section allowed by the lower electric winch. The cable tension sensor and wireless information transmission module and its protective cover are installed on the cable at the traction section between the traction cable sections allowed by the middle and lower electric winches. The order of cable traction is as follows: horizontal cable conveyor, lower electric winch, middle electric winch, and upper electric winch. The laying process of the traction cable section allowed by the lower electric winch is the same as the laying process of the traction cable section allowed by the middle electric winch.

[0017] Step 7. When the high-level electric winch vertically lifts the large-section cable to the installation height of its highest wire rope guide roller or the middle-level and low-level electric winches have vertically lifted the cable to the permitted length, stop all cable pulling mechanisms, verify that the actual vertical lifting length of the large-section cable meets the requirements, and then begin corrugated laying of the large-section cable from the bottom of the electrical shaft. During the corrugated fixing process of the large-section cable, the upper high-level, middle-level, and low-level electric winches lower the reserved length required for corrugated laying in sequence. At the same time, remove the corresponding binding mechanisms for connecting the auxiliary steel wire rope to the cable outer sheath, the auxiliary steel wire rope, and the traction steel wire ropes of the middle-level and low-level electric winches;

[0018] Step 8. When the large-section cable waveform is fixed to the main equipment layer of the high-rise building, the high-rise electric winch lowers the remaining large-section cable to the main equipment layer and removes the traction wire rope from the cable traction head. The cable is then guided by the operator and pulled by the cable conveyor to lay the cable horizontally on the main equipment layer.

[0019] In some embodiments, the process control of the cable pulling and laying includes:

[0020] Step 1. Before laying the cable, confirm the specific vertical lifting plan, specific process control procedures, and actual on-site compliance. If there are any discrepancies, make corrections in a timely manner or modify the plan or process control procedures according to existing procedures.

[0021] Step 2. Lay out related facilities for vertical lifting of large-section cables according to the specific vertical lifting plan, conduct corresponding inspections, confirmations, and operations. Simultaneously, deploy corresponding video and safety monitoring systems and confirm relevant control parameters and key safety monitoring measures.

[0022] Step 3. The vertical lifting process of large-section cables is controlled by the cable synchronous traction protection unit of the video and safety monitoring organization and the operating personnel responsible for real-time monitoring according to the specific process control procedures. When there is a set parameter alarm or a dangerous process status during the vertical lifting process of large-section cables, the cable synchronous traction protection unit or the operating personnel responsible for real-time monitoring will promptly issue an alarm or perform a hazard elimination operation. When the set protection parameters are reached or danger is about to occur, the cable synchronous traction protection unit or the operating personnel responsible for real-time monitoring will stop the traction protection operation.

[0023] Compared with the prior art, the beneficial effects of the embodiments of the present application are:

[0024] (1) Taking advantage of the fact that the main equipment layer of a high-rise building is located in the upper floors, the length of the large-section cable horizontally laid on the main equipment layer of the middle and upper floors of the high-rise building is relatively short relative to the height of the floors above the main equipment layer. The electrical shaft in a high-rise building is generally accessible from top to bottom. The length of the high-rise horizontal channel is first vertically lifted in the electrical shaft, and finally, after the waveform of the lower part of the cable is fixed in the electrical shaft, the cable is lowered for horizontal section laying. This laying method can avoid the selection and implementation of the following two more cumbersome construction processes.

[0025] The first method is to use a method of directly converting a large-section cable into a horizontal laying method after vertically lifting it in an electrical shaft. When the large-section cable is vertically lifted by an electric winch to the height of the main equipment of a high-rise building, the cable or auxiliary steel wire rope will be subjected to a large pulling force. If the method of directly converting the large-section cable into a horizontal laying method is adopted at this time, when the large-section cable or the auxiliary steel wire rope is subjected to a large pulling force, the large-section cable will be subjected to a large lateral pressure which may exceed its allowable value. When the setting spacing and turning radius of the steering roller do not meet the requirements, the outer sheath of the large-section cable is more likely to be damaged. This method is difficult to control the outer sheath of the large-section cable from being damaged, and the cable laying control process is relatively cumbersome. This method is not selected when there is no safer measure to ensure that the lateral pressure borne by the large-section cable does not exceed the allowable value.

[0026] The second is a laying method that switches the electric winch wire rope traction point downward. This method requires pre-installing an electric or manual hoist at the highest traction wire rope roller of the electric winch as a switching device for vertically lifting large-section cables when the traction point is switched downward. Suitable cable traction points and corresponding cable outer sheath allowable traction force measures must also be pre-installed at appropriate positions below the traction point of the large-section cable end. The auxiliary wire rope length and binding workload required for vertical lifting of large-section cables are large, so this laying method is also relatively cumbersome. This patent adopts a one-time vertical lifting into place in the electrical shaft and the cable waveform in the electrical shaft is fixed. The cable laid horizontally on the main equipment layer is laid under very small traction force. The vertical lifting of the cable in the electrical shaft and the horizontal laying on the main equipment layer are relatively simple. The traction force and lateral pressure borne by the large-section cable are easy to control, and the process efficiency is relatively high.

[0027] (2) This patent takes advantage of the fact that the large cross-section cable core allows a larger pulling force, and adopts a method of connecting the cable pulling head with the large cross-section cable core, instead of adopting the general method of using a wire mesh sleeve at the cable end to apply pulling force to the cable outer sheath. As a result, the cable section for pulling by connecting the cable pulling head with the large cross-section cable core has a relatively large length, which relatively reduces the workload of tying and connecting the auxiliary steel wire rope with the cable outer sheath, and simplifies the complexity of the cable laying process without considering the lateral pressure on the cable.

[0028] (3) A binding mechanism is used to quickly connect and disassemble the auxiliary steel wire rope and the cable outer sheath. The material of the binding mechanism is rubber or nylon material with high friction with the steel wire and the cable outer sheath material and with high-strength synthetic fiber as the base. The width of the binding mechanism is about 20 to 100 mm. Depending on the width of the binding mechanism, 2 to 5 tie straps connected side by side will be used at the position where a pair of cables are connected to the steel wire rope. A pair of binding mechanisms have a matching plug-in buckle structure at the tail end and a pair of binding mechanisms can be respectively bound and connected with the cable outer sheath and the steel wire rope, that is, a pair of binding mechanisms are respectively bound and connected with the cable outer sheath and the steel wire rope and then connected together with the matching plug-in buckle structure at the tail end. The use of the binding strap can enable the auxiliary steel wire rope to be quickly connected and disassembled with the cable outer sheath, thereby improving the safety and process efficiency of the binding of the auxiliary steel wire rope and the cable outer sheath.

[0029] (4) A method is adopted in which large-section cables including the designed length above the bottom of the electrical shaft, the reserved length for corrugated laying and the reserved length at the cable terminal or intermediate joint are vertically lifted in the electrical shaft of a high-rise building, and then the large-section cables are fixed in a corrugated manner from bottom to top or in sections in the electrical shaft, and finally the large-section cables are laid in a high-rise horizontal channel with less traction and lateral pressure. The setting of the reserved length for corrugated laying ensures the laying quality of the large-section cables, and the fixing of the large-section cables in a corrugated manner from bottom to top or in sections in the electrical shaft ensures that the traction force borne by the cables can be controlled safely.

[0030] (5) In general, two electric winches are used. In special cases such as super-high-rise buildings, more than two electric winches are used. The electric winches are segmented and redundant for vertical lifting. A tension sensor is installed at the head of the electric winch traction wire rope, and a cable tension sensor is installed at the electric winch traction cable segment. The traction force detection control and redundancy are used for cable traction segmentation and tension detection control are used at the cable redundant segment. This forms a dual and redundant control of the traction force in the cable vertical lifting process, and is a cable vertical lifting process with reliable cable traction force control.

[0031] (6) A traction distance sensor is installed on the drum shaft of the electric winch to measure the cable length allowed to be pulled by each electric winch to prevent the actual cable length pulled by the winch from exceeding the limit. The traction distance sensor can also provide a distance limit based on the time limit for the sequential start-up between the cable conveyor and the electric winch, so as to better meet the synchronization function application of the cable synchronous traction protection unit.

[0032] (7) A buffer section for connecting the auxiliary steel wire rope segment and the cable outer sheath is set on the ground at the bottom of the electrical shaft, which facilitates the quick connection between the auxiliary steel wire rope and the cable outer sheath using a new type of binding belt, so that the binding connection between the auxiliary steel wire rope and the cable outer sheath can be quickly carried out when the cable is stopped in stages during the vertical lifting process. At the same time, the buffer section for connecting the auxiliary steel wire rope segment and the cable outer sheath at the bottom of the electrical shaft can be set to a semi-circular arc shape and the cable roller is not fixed. The change in the radius of the semi-circular arc cable roller can be used to judge the change in the traction force at the horizontal laying and vertical lifting sections on the ground. The size of the radius of the semi-circular arc cable roller can be adjusted by pausing or adjusting the speed of the electric winch of the vertical lifting part, so that the vertical lifting section does not bear the traction force of the horizontal laying on the ground, ensuring that the traction force of each section of the vertical lifting section can also be controlled within the allowable traction force range.

[0033] (8) Sensor information and control information are transmitted through wireless information transmission modules and remote wireless information transceivers and information input and output devices. Tension sensors, traction distance sensors, cable conveyors and electric winches can form a safety monitoring system with cable synchronous traction protection units that is not restricted by on-site space and distance, and can better meet the real-time process safety control requirements of the cable vertical lifting process.

[0034] (9) Wireless video sub-units can be installed for real-time monitoring at important locations or locations where there is a risk of jamming, twisting, loosening, or slipping on large-section cable laying channels. Video surveillance facilities of the smart construction site system can also be used for real-time monitoring. The long-distance video surveillance function improves the convenience of real-time monitoring of the cable laying process, which is conducive to quickly discovering problems and handling them in a timely manner.

[0035] (10) In order to meet the requirements of instant and rapid safety management of large-section cable vertical lifting, a handheld mobile terminal management system and a computer management system are used as video human-computer interaction terminals to realize process monitoring, parameter display, parameter over-limit alarm, authorized start and stop cable traction control functions of the video and safety monitoring control system, as well as real-time monitoring of the cable laying facilities involved in the video and safety monitoring system itself and other parts involved in the cable laying process.

[0036] (11) Through the handheld mobile terminal management module or computer management system, the calculation function of the microprocessor control processing unit of the construction site smart site system or video and safety monitoring system can be used to calculate the various parameters required for vertical lifting of large-section cables. The specific vertical lifting plan and specific process control procedures and key safety monitoring measures are prepared by electrical professional technicians and approved by the construction site smart site system according to the required procedures. The relevant content can be called, executed according to the required procedures, confirmed and replied, and modified according to the determined authority through the handheld mobile terminal management module or computer management system.

[0037] (12) Utilize the existing smart construction site system at the construction site and the specific vertical lifting plan, specific process control procedures, key safety monitoring measures and various parameters required for vertical lifting of large-section cables based on the smart construction site system, as well as channels for obtaining external resources through the smart construction site system. With the smart construction site system as the basis, the handheld mobile terminal management module and the computer management system as auxiliary means of process safety management, authorized operators can conduct real-time monitoring and process confirmation of the cable laying process through the video and safety monitoring system and the smart construction site system, thereby improving the efficiency of safety monitoring of the cable vertical lifting process and realizing dual safety monitoring of the cable vertical lifting process by the cable synchronous traction protection unit and authorized operators through the video and safety monitoring system and the smart construction site system.

[0038] (13) The voice information exchange and warning service function of the information exchange and warning service unit is based on the video and security monitoring unit, the cable synchronous traction and displacement protection unit and the construction site smart site information resources, and can realize the voice information exchange, warning, control operation and other functions of the entire process of cable traction and displacement.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0068] In one or more embodiments of the present invention, please refer to Figure 1-Figure 2 The present invention is a construction method based on the wire rope traction and lifting laying technology, which has been improved accordingly in practice. It mainly uses a cable pulling head to pull the metal core wire of the large-section cable 4, utilizes the traction force allowed by the large-section cable 4 itself, and pulls the large-section cable 4 in sections and synchronously, further reducing the actual traction force borne by the cable. Taking advantage of the fact that the electrical shaft in a high-rise building is long and the actual vertical cable traction length is relatively short, the cable is directly lifted by the electrical shaft instead of the secondary switching and lifting at the highest traction point. At the same time, the length of the auxiliary wire rope lifting cable and its corresponding operation process are also reduced. On the basis of the above process improvements, this patent also applies video and safety monitoring mechanisms in the process of vertical cable laying, which greatly improves the safety and efficiency of the vertical cable lifting process.

[0069] By utilizing the fact that the main equipment layer of a high-rise building is located in the upper floors, the length of the large-section cable 4 horizontally laid on the main equipment layer of the middle and upper floors of the high-rise building is shorter than the height of the floors above the main equipment layer, and avoiding the large-section cable 4 being subjected to a lateral pressure exceeding the allowable value when the cable is horizontally laid to the main equipment layer through the cable steering roller when the large-section cable 4 is subjected to a large traction force, or not choosing to adopt the method of vertically lifting the large-section cable 4 and then using a hand winch to assist in moving the highest-end cable traction point down to the auxiliary steel wire rope 24 of the segmented traction below the cable position with the same length as the horizontal laying of the main equipment layer and then vertically lifting it again, the design cable length above the bottom of the electrical shaft, including the cable waveform laying and the reserved margin for the cable end or intermediate joint, is vertically lifted once in the electrical shaft, and the cable waveform is fixed to the main equipment layer of the middle and upper floors in the electrical shaft, and then the cable is horizontally laid in place along the main equipment layer. The method of vertically lifting the large-section cable 4 into place once in the electrical shaft improves the process laying efficiency.

[0070] The main reasons for choosing to use two or more electric winches to vertically lift large-section cables 4 in the electrical shaft are: in general, the traction force of the electric winch is much greater than the traction force allowed by the cable, and the traction force allowed by the cable pulling head 41 connected to the cable core is also much greater than the traction force allowed by the steel mesh or cable clamp connected to the cable outer sheath. The scheme of using a high-rise electric winch wire rope 21 and a cable pulling head 41 connected to the cable core for traction in the electrical shaft can fully utilize the large traction force advantage of the large traction force of the large-section cable 4 itself, and there is no need to use auxiliary steel wire ropes 24 for traction in sections within the allowable traction force range; since the middle part of the large-section cable 4 can only be connected to the cable outer sheath 4 with a steel mesh or cable clamp 6 connection, plus the traction force allowed by the cable outer sheath 46 is relatively small, so the large-section cable 4 part that exceeds the allowed traction of the cable core needs to be pulled by multiple points in sections. If each section point uses a traction machine, it will be an inappropriate traction scheme. Generally, a wire mesh sleeve or a cable clamp is used to connect the cable outer sheath 46 at multiple points in sections, that is, an auxiliary steel wire rope 24 is required to be connected to the cable outer sheath 46 in sections and then pulled by the middle-level electric winch 12 and the low-level electric winch 13. Generally, two high-level electric winches 11 and middle-level electric winches 12 are arranged for segmented traction. When it is a super high-rise building, more than two high-level electric winches 11, middle-level electric winches 12 and low-level electric winches 13 are required.

[0071] In general, the process of connecting and disassembling the cable outer sheath 46 in sections and multiple points using a wire mesh sleeve or a cable bolt fixing fixture is relatively difficult and cumbersome. The wire mesh sleeve is generally only used for the cable end. When used in the middle part of the cable, it is difficult to insert and needs to be improved. When the cable bolt fixing fixture is used, the bolt fixing and disassembly process is time-consuming and cumbersome, and it is easy to get stuck during vertical traction. The present invention adopts a binding mechanism 5 to make corresponding improvements on the connection between the auxiliary steel wire rope 24 and the cable outer sheath 46 on the basis of the nylon cable tie. The nylon cable tie can quickly bind objects, but its disassembly process is relatively difficult. The present invention utilizes the advantages of the nylon cable tie for fast binding and makes corresponding improvements in solving the traction tension, friction and fast connection and disassembly. The main improvements to the binding mechanism 5 are: using rubber or nylon material with high-strength synthetic fiber as the base to solve the traction tension and friction of the new binding belt 5 Friction problem; the method of widening the width of the new cable tie and tying multiple new cable ties side by side is adopted to further solve the traction tension and friction problems of the new cable tie 5; the method of adding a flat matching buckle at the tail of the new cable tie is adopted to solve the problem of quick connection and disassembly of the new cable tie 5 after tying the auxiliary steel wire rope 24 and the cable outer sheath 46 respectively; the method of adding a pressurized movable self-locking tooth belt at the head of the new cable tie is adopted to solve the problem that it is difficult to pass through the head of the cable tie when a flat matching buckle is added to the tail of the tying mechanism 5, as well as the problem of self-locking and quick unlocking of the middle tooth belt 52 of the cable tie with its head; in order to better ensure the quality problem of self-locking of the middle tooth belt 52 of the cable tie with its head, corresponding tooth belts are arranged on the upper and lower sides of the middle base belt of the cable tie, and the cable tie with tooth belts on the upper and lower sides and the pressurized movable self-locking tooth belts and fixed tooth belts on the upper and lower sides of its head can form a better self-locking state.

[0072] The high-rise electric winch 11 is disposed above the main equipment floor 8, and the height of its wire rope guide roller 33 is calculated based on the designed laying length of the large-section cable 4 above the bottom of the electrical shaft and the length required for the reserved wave-shaped laying and the terminal or intermediate joint length. In other words, in the relatively special environment of a high-rise building, the laying of the large-section cable 4 is characterized by a relatively small horizontal laying amount on the main equipment floor 8, while the length of the electrical shaft of the high-rise building is relatively long. The large-section cable 4 can be vertically lifted into position in the electrical shaft once and then horizontally laid on the main equipment floor 8. This method of vertical lifting in the electrical shaft once can avoid damage to the large-section cable 4 due to excessive pressure on the turning side when the large-section cable 4 is subjected to large traction when switching from vertical lifting to horizontal laying. Alternatively, it is not necessary to lift the large-section cable 4 to the main equipment floor 8 and then lower the traction lifting point before lifting it again when the large-section cable 4 is subjected to large traction. The present invention utilizes a method of vertical lifting in the electrical shaft once and horizontally laying the large-section cable 4 on the main equipment floor 8 without being subjected to large traction, which has high process efficiency.

[0073] The high-rise electric winch traction wire rope 21 is connected to the large-section cable 4 for vertical traction using a cable traction head 41, that is, the high-rise electric winch traction wire rope 21 is connected to the cable core 45 of the large-section cable 4, utilizing the larger allowable traction force of the cable core 45 of the large-section cable 4 without the need to use auxiliary wire ropes 24 to perform segmented multi-point connections on the cable outer sheath 46 within the longer range of the traction cable length allowed by the high-rise electric winch 11, thereby reducing the corresponding process workload.

[0074] A cable traction head 41, a cable anti-twist device 42, a tension sensor 631 and a wireless information transmission module 636 and their protective covers 43 are installed between the high-rise electric winch traction wire rope 21 and the cable core 45 of the large-section cable 4. The installation of the cable anti-twist device 42 can prevent the large-section cable 4 from being damaged by traction torque during the traction process. The tension sensor 631 and the wireless information transmission module 636 are installed at the maximum value of the traction force borne by the large-section cable 4. The wireless information transmission module 636 can send the maximum traction force value detected by the tension sensor 631 to the cable synchronous traction protection information processing unit 612 of the microprocessor control processing unit 61 for real-time calculation and processing, and compare it with the allowable traction force limit and protection value of the large-section cable 4 in real time to meet the traction control requirements of the vertical lifting process of the large-section cable 4.

[0075] A traction distance sensor 633 is installed on the drum shaft of the high-rise electric winch 11. The traction distance sensor 633 can be sent to the cable synchronous traction protection information processing unit 612 of the microprocessor control processing unit 61 for real-time calculation and processing through the remote wireless information receiving and sending and information input and output device 637 installed on the high-rise electric winch 11. The calculation result is mainly used for controlling the allowable traction length of the cable traction mechanism 1 and controlling the traction distance when the cable traction mechanism 1 is started sequentially, especially for controlling the allowable traction length of the electric winch. It is also a double protection for controlling the allowable traction force limit and protection value of the large-section cable 4. In addition, the operating personnel use the handheld mobile terminal management module 641 or the computer management module 642 and on-site real-time management to form multiple protections against dangerous situations in the traction process of the large-section cable 4, which greatly improves the safety of the vertical lifting process of the large-section cable 4.

[0076] Among them, the large-section cable 4 is mainly vertically lifted in the electrical shaft channel and pulled and laid in the horizontal channel. Cable vertical guide rollers 32 should be installed at each floor opening and blocked location in the vertical lifting channel of the electrical shaft. The cable vertical guide rollers 32 should be installed on the vertical lifting line as much as possible to reduce the resistance during vertical lifting and the lateral pressure on the cable; cable horizontal guide rollers 31 are installed on the horizontal channels of the main equipment layer 8 and the bottom of the electrical shaft. In particular, it is necessary to use the cable horizontal guide rollers 31 to set up a multi-point connection buffer section between the auxiliary steel wire rope 24 and the cable outer sheath 46 in the horizontal cable laying channel at the bottom of the electrical shaft or the surrounding available space to facilitate the safe and quick connection of the auxiliary steel wire rope 24 with the cable outer sheath 46. At the bottom of the electrical shaft where the auxiliary steel wire rope 24 and the cable outer sheath 46 are connected, a segmented buffer zone for the vertical lifting section of the large-section cable 4 and the ground horizontal pulling section is also required to facilitate segmented pulling of the cables in the vertical lifting section and the ground horizontal pulling section of the large-section cable 4, ensuring that the traction force of each traction section of the large-section cable 4 is controlled within the allowable range.

[0077] The high-rise electric winch 11 allows the traction length to be pulled into place, which is controlled by the traction distance sensor 633 installed on the drum shaft of the high-rise electric winch 11 and the real-time monitoring of the vertical traction of the large-section cable 4 by the on-site workers. It is also a dual protection measure that adapts to the particularity of the construction site; the high-rise electric winch 11 allows the traction length to be pulled into place, which is automatically controlled to stop by the cable synchronous traction protection unit 63 or stopped by the workers through voice or button; for the segmented multi-point connection of the auxiliary steel wire rope 24 and the cable outer sheath 46, the segmented multi-point connection of the auxiliary steel wire rope 24 and the cable outer sheath 46 can be carried out when the traction speed of the cable traction mechanism 1 is slow, but there are uncertain safety factors. The present invention is from the perspective of safety. From this perspective, an auxiliary steel wire rope segment and cable outer sheath segment multi-point connection buffer section 47 is set in the horizontal cable laying channel at the bottom of the electrical shaft or in the surrounding available space. When the cable traction mechanism 1 stops running, the auxiliary steel wire rope 24 and the cable outer sheath 46 are segmented and multi-point connected in this longer buffer section. After each connection is completed, all cable traction mechanisms 1 are started and pulled in a determined starting sequence. When the traction of one auxiliary steel wire rope 24 and cable outer sheath 46 segment multi-point connection section is completed, the traction is stopped and the next auxiliary steel wire rope 24 and cable outer sheath 46 segment multi-point connection is carried out, until the auxiliary steel wire rope 24 and cable outer sheath 46 segment multi-point connection within the traction length allowed by the cable traction mechanism 1 is completed.

[0078] The cable conveyor 14 in the cable traction mechanism 1 is the first to start pulling the large-section cable 4. Then, in the process of vertical lifting and laying of the cable, the high-level electric winch 11, the middle-level electric winch 12, and the low-level electric winch 13 are sequentially added. The four cable traction mechanisms 1 are started sequentially using a time mode or a traction distance mode. Both modes can be operated by the cable synchronous traction protection unit 63 and the operator through voice or button operation according to the actual situation on site. The traction distance control can be determined based on the traction distance sensor 633 and the cable synchronous traction protection unit 63 according to the relevant parameters set by the operator according to the actual situation on site.

[0079] The order in which the electric winch traction wire rope is guided downward along the vertical guide roller 32 of each cable layer in the electrical shaft is the low-level electric winch traction wire rope 23, the middle-level electric winch traction wire rope 22, and the high-level electric winch traction wire rope 21. When the middle-level electric winch traction wire rope 22 and the high-level electric winch traction wire rope 23 are guided to the bottom of the electrical shaft, they should be straightened and fixed to prevent the large-section cable 4 from being stuck when vertically lifted; when the middle-level electric winch traction wire rope 22 and the low-level electric winch traction wire rope 23 are connected to the auxiliary wire rope 24, the cable anti-twist device 42, the tension sensor 631 and the wireless information transmission module 636 and their protective covers 43 are also installed. Corresponding traction distance sensors 633 are also installed on the drum shafts of the middle-level electric winch 12 and the low-level electric winch 13. The corresponding functions are the same as the traction force and traction distance control requirements of the high-level electric winch 11 circuit.

[0080] A cable tension sensor 632, a wireless information transmission module 636 and a protective cover 43 are installed on the upper end of the large-section cable 4 at the connection point between the traction wire rope 22 of the middle-level electric winch and the auxiliary wire rope 24. The location where the cable tension sensor 632 is installed is the segment where the large-section cable 4 is vertically pulled between the high-level electric winch 11 and the middle-level electric winch 12. It is a double protection based on the control of the traction force allowed by the large-section cable 4 after the tension sensor 631 is used in the cable synchronous traction protection unit 63. It is also a way to ensure the safe vertical lifting of the large-section cable 4 when the construction process is relatively greatly affected by factors such as people, objects, environment, and management. Method, the installation position of the cable tension sensor 632 is the segment or dividing point of the allowable traction length of two adjacent electric winches. Since this segment or dividing point moves with the large-section cable 4, the cable tension sensor 632 and the wireless information transmission module 636 are used to detect and wirelessly transmit the corresponding information of the traction force borne by the large-section cable 4 at this segment or dividing point. Under normal circumstances, the traction force borne by the large-section cable 4 at this segment or dividing point should be the smallest. According to this feature, the traction force of the cable tension sensor 632 should be controlled within the traction force range involved in the allowable traction margin or safety factor calculated by the upper electric winch.

[0081] Among them, the position of the segment for vertically pulling the large-section cable 4 between the high-level electric winch 11 and the middle-level electric winch 12 is determined based on the way the end of the large-section cable 4 is connected with the cable core 45 using the cable pulling head 41 and the length of the large-section cable 4 allowed to be pulled by the high-level electric winch pulling wire rope 21, and taking into account the corresponding safety margin; the position of the segment for vertically pulling the large-section cable 4 between the middle-level electric winch 12 and the low-level electric winch 13 is determined based on the allowable pulling force of the electric winch and the auxiliary wire rope 24, the actual allowable pulling force of the tying mechanism 5, and the specific conditions on site. It is determined that the traction force limit value at the segmented multi-point traction using the auxiliary steel wire rope 24 is mainly determined by the safety margin of the allowable traction force and the actual traction force limit that the large-section cable 4 can withstand. Since each electric winch is pulling a large-section cable 4 of a determined length under the allowable traction force control, the cable tension sensor 632 installed at each segment or boundary is the main control process for the vertical traction synchronous control of multiple electric winches based on the tension sensor 632 installed at the traction wire rope. The two traction control processes form a dual protection for the vertical traction synchronous control of the large-section cable 4.

[0082] Please refer to Figure 2The high-level electric winch 11, the middle-level electric winch 12, and the low-level electric winch 13 pull the large-section cable 4 in sections. The vertical lifting process of the large-section cable 4 is controlled by synchronous segmented traction. The method of synchronous segmented traction control is mainly as follows: during the vertical lifting process of the large-section cable 4, the allowable traction lengths of the high-level electric winch 11, the middle-level electric winch 12, and the low-level electric winch 13 added in the traction order are controlled by the traction distance sensor 633, so that the length of the large-section cable 4 pulled by each electric winch is limited to its allowable traction length, and segmented traction control is performed indirectly. A semi-circular buffer zone 48 is set at the bottom of the electrical shaft for the vertical lifting section and the horizontal laying section, so that the large-section cable 4 does not bear the weight of the horizontal section when it is vertically lifted in the electrical shaft, ensuring that the vertical lifting section and the horizontal laying section can be pulled in sections without affecting each other; this is also a safety measure for the corresponding segmented traction control. The sequential activation of the cable conveyor 14, the lower-level electric winch 13, the middle-level electric winch 12, and the upper-level electric winch 11 allows for a reasonable margin of large-section cables 4 between each traction segment, preventing the traction force between segments from exceeding the segment boundaries and being applied to adjacent segments. This is also an important safety measure for segmented traction control. The traction force exerted on the large-section cables 4 or auxiliary steel wire ropes 24 is monitored in real time by the tension sensors 631 installed on the traction wire ropes 21 of the upper-level electric winch, the traction wire ropes 22 of the middle-level electric winch, and the traction wire ropes 23 of the lower-level electric winch. When the traction force reaches the allowable limit or protection value, an alarm is issued, and the process is adjusted or operation is stopped. Cable tension sensors 632 installed at the upper, middle, and lower sections of the electric winch allowable traction length provide real-time monitoring of the traction force exerted on the traction sections of the large-section cable 4. When the allowable traction force limit or protection value is reached, an alarm is issued, and process adjustments or operation is stopped. The detection information of tension sensors 631 and cable tension sensors 632 is transmitted through the cable synchronous traction protection unit 63 to form dual synchronous traction protection. Authorized operators can monitor and confirm the cable laying process in real time through the video and safety monitoring mechanism 6 and the smart construction site system 7. The cable synchronous traction protection unit 62 and authorized operators can also use the video and safety monitoring mechanism 6 and the smart construction site system 7 to form dual safety monitoring of the cable vertical lifting process.

[0083] Please refer to Figure 3a-Figure 3bCurrently, the main connection methods for the auxiliary steel wire rope 24 and the cable outer sheath 46 are steel mesh sleeves and cable bolt fixing clamps. Due to the relatively long length of the large-section cable 4, the steel mesh sleeve is difficult to insert into the middle part of the cable, and the cable bolt fixing clamp is relatively cumbersome to clamp, connect, and remove. This is an improvement on the currently commonly used nylon cable ties. It uses a binding mechanism 5 to bind the auxiliary steel wire rope 24 and the cable outer sheath 46 separately, and then the two binding straps are connected by snap-fit. In order to increase the contact area between the binding strap and the auxiliary steel wire rope 24 and the cable outer sheath 46 to increase the friction between the corresponding contact surfaces and reduce the lateral pressure on the cable outer sheath 46, a relatively wide binding base belt 51 is used. The widening of the binding base belt 51 includes two parts: the first part is to change the width of the binding base belt 51 to about 20 to 100 mm, and the second part is to use 2 to 5 widened binding base belts 51 connected side by side to form a binding mechanism 5.

[0084] Among them, the binding straps that respectively bind the auxiliary steel wire rope 24 and the cable outer sheath 46 at the same position are a group of binding mechanisms 5 that are paired with each other. The tail of a group of binding mechanisms 5 is a plurality of tail flat card frames or claws 54. The flat claws of the flat card frames or claws 54 at the tail of a group of binding straps can be inserted into the corresponding flat card frames and have the ability to withstand the required traction force.

[0085] The tying mechanism 5 is composed of a plurality of ties connected side by side, each of which is composed of a tying base belt 51, an intermediate toothed belt 52, a head flat card frame 53, and a tail flat card frame or buckle 54. The tail flat card frame or buckle 54 needs to pass through the head flat card frame 53. Since the tail flat card frame or buckle 54 is thicker than the tying base belt 51 and the intermediate toothed belt 52, the opening of the head flat card frame 53 is relatively large, so it is necessary to add a head movable part in the head flat card frame 53. The self-locking pressure lifting belt 531 with latch teeth, the head movable self-locking pressure lifting belt 531 is connected to the edge of the card frame on one side of the flat card frame 53 of the head and can be rotated inward or outward along the mutual connection line. When the self-locking pressure lifting belt 531 with latch teeth passes through the flat card frame 53 of the head, the self-locking pressure lifting belt 531 with latch teeth can be pushed open. After the self-locking pressure lifting belt 531 with latch teeth passes through the flat card frame 53 of the head, the self-locking pressure lifting belt 531 with latch teeth can be pressed back into the flat card frame 53 of the head.

[0086] In order to improve the self-locking performance of the binding mechanism 5 after binding the auxiliary steel wire rope 24 and the cable outer sheath 46, the middle upper and lower parts of the binding base belt 51 of the binding mechanism 5 are provided with intermediate toothed belts 52. Similarly, the head movable tooth self-locking pressure belt 531 and the inner side of the flat card frame 53 and the intermediate toothed belts 52 on both sides of the binding base belt 51 are provided with matching head flat card frame toothed belts 532 for self-locking.

[0087] In order to increase the strength of the binding mechanism 5 and the friction with the auxiliary steel wire rope 24 or the cable outer sheath 46 and the protection of the cable outer sheath, the material of the cable tie is made of rubber or nylon material with a large friction with the auxiliary steel wire rope 24 or the cable outer sheath 46 and with a high-strength synthetic fiber as the base. The width of the cable tie is changed to about 20 to 100 mm, and the tail of the cable tie is a matching flat card frame or buckle claw 54 of an inserted buckle structure. The flat card frame or buckle claw 54 at the tail of the cable tie can pass through the flat shape of the cable tie head. The locking teeth in the flat clamping frame 53 of the cable tie head are solved by the self-locking pressure belt 531 of the movable clamping teeth on the head. In actual use, in order to prevent the concentration of force at the connection position of the auxiliary steel wire rope 24 and the cable outer sheath 46 and from a safety perspective, according to the different widths of the cable tie, 2 to 5 new cable ties connected side by side will be used at the connection position of an auxiliary steel wire rope 24 and the cable outer sheath 46 to ensure reliable connection and multiple protections and prevent the cable outer sheath 46 from being damaged due to concentrated force.

[0088] The quick connection process of the auxiliary steel wire rope 24 and the cable outer sheath 46 using the tying mechanism 5 is as follows: for one connection point of the auxiliary steel wire rope 24 and the cable outer sheath 46, a group of tying mechanisms 5 consisting of 2 to 5 ties connected side by side are used. The plug-in buckle structure at the tail of the tying mechanism 5 is a pair of matching flat card frames and buckle claws 54. The group of tying mechanisms 5 are tied and connected with the auxiliary steel wire rope 24 and the cable outer sheath 46 respectively. After the tying mechanism 5 is wrapped around the auxiliary steel wire rope 24 or the cable outer sheath 46, the tying mechanism 5 is tied and connected with the auxiliary steel wire rope 24 or the cable outer sheath 46. After the flat card frame or buckle 54 at the tail passes through the flat card frame 53 at the head, the head movable card tooth self-locking pressure belt 531 attached to the flat card frame 53 at the head of the binding mechanism 5 is pressed into the flat card frame 53 at the head so that the binding mechanism 5 can be in a force-bearing self-locking state after wrapping the auxiliary steel wire rope 24 or the cable outer sheath 46. Subsequently, all the buckles at the tail of a group of 2 to 5 flat card frames or buckles 54 at the tail of the binding mechanism 5 connected side by side are inserted side by side into their matching flat card frames to form an inserted buckle structure.

[0089] When it is necessary to disassemble the binding mechanism 5, a group of flat clamping frames at the tail of the binding mechanism 5 or the flat claws in the claws 54 are pulled out from the flat clamping frames, so that the auxiliary steel wire rope 24 and the cable outer sheath 46 are connected and separated. The binding belts tied on the auxiliary steel wire rope 24 and the cable outer sheath 46 can release the self-locking state of the binding mechanism 5 by lifting the head movable clamping teeth self-locking pressure belt 531 in the flat clamping frame 53 at the head of the binding mechanism 5, thereby removing the binding mechanism 5 from the auxiliary steel wire rope 24 or the cable outer sheath 46.

[0090] Please refer to Figure 4As can be seen from the figure, the video and safety monitoring mechanism 6 includes a microprocessor control processing unit 61, a video and safety monitoring unit 62, a cable synchronous traction protection unit 63, and an information exchange and warning service unit 64. The video and safety monitoring system 6 is also a safety monitoring system for vertically lifting large-section cables based on the existing smart construction site system 7 at the construction site; among them, the microprocessor control processing unit 61 adopts a small computer module to realize the function of quickly calculating and processing input and output information according to the required program, mainly including a video information processing unit 611, a cable synchronous traction protection information processing unit 612, an information exchange and warning service information processing unit 613, and a wireless information transmission module 636; the microprocessor control processing unit 61 can also carry out corresponding information communication and resource sharing with the smart construction site system 7 at the construction site; the microprocessor control unit 61 can be set at a position with a stable power supply and smooth wireless information in the vertical lifting channel of the large-section cable 4.

[0091] The cable synchronous traction protection unit 63 collects the traction force value of each electric winch on the large-section cable 4 through the tension sensor 631, obtains the traction force value of each electric winch at the section where the large-section cable 4 is allowed to be pulled through the cable tension sensor 632, and obtains the traction distance value of each electric winch through the traction distance sensor 633. The traction force and traction distance values ​​are wirelessly transmitted to the cable synchronous traction protection information processing unit 612 of the microprocessor control processing unit 61 for corresponding information calculation and processing, forming a dual closed-loop control of the traction force of the electric winch and the traction force at the section where the large-section cable 4 is allowed to be pulled between the electric winches, and the limit value and protection value are set by authorized electrical professionals. The dual protection is set taking into account the particularity of the construction site that is different from the factory. The setting of the dual protection can discover problems such as system component failure caused by uncertainty at the construction site, thereby ensuring the safety of the synchronous control process of the vertical lifting process of the large-section cable 4 and the actual laying quality of the large-section cable 4.

[0092] The cable synchronous traction protection unit 63 obtains the traction distance value through the traction distance sensor 633, forming a time control mode or traction distance control mode for controlling the traction length limit of the electric winch traction of the large-section cable 4 and the sequential start-up of multiple cable traction mechanisms 1; wherein, the control information of the cable synchronous traction protection unit 63 is input into the winch traction device traction control unit 634 and the cable conveyor traction control unit 635 through the remote wireless information transceiver and information input and output device installed on the cable traction mechanism 1, and then directly controls the start and stop of the electric winch and cable conveyor. The winch traction device traction control unit 634 and the cable conveyor traction control unit 635 are the control circuits of the electric winch and cable conveyor, which can be PLC control circuits, variable frequency speed regulation circuits, or hard-wired circuits.

[0093] Cable-related parameters, traction parameters of the cable traction mechanism 1 and other information can be input through the handheld mobile terminal management module 641 and the computer management module 642. The microprocessor control processing unit 61 can use the corresponding calculation processing software to calculate and display the setting spacing of the cable horizontal guide roller 31 and the cable vertical guide roller 32, the segmented traction method when the type and number of the cable traction mechanism 1 are known, and the limit and protection values ​​of the traction force detection information of the tension sensor 631 and the cable tension sensor 632 according to the corresponding parameters of the cables of different models and cross-sections. After the relevant information is confirmed by professional technicians, the alarm and protection values ​​of the tension sensors 631 and the cable tension sensors 632 of different models, cross-sections and different parts are assigned.

[0094] The cable pulling mechanism 1 can only be started by authorized personnel through the recognizable voice system or button of the handheld mobile terminal management module 641 or the computer management module 642. The cable pulling mechanism 1 can be stopped by authorized personnel through the recognizable voice system or button of the corresponding handheld mobile terminal management module 641 or the computer management module 642. Multiple cable pulling mechanisms 1 can be started and stopped sequentially and can be started by authorized personnel through voice or button. The cable synchronous pulling protection unit 63 performs process control according to the set starting sequence and delay time or pulling distance. The pulling distance can be measured by the pulling distance sensor 633 to provide corresponding measurement data. The starting sequence and delay time or pulling distance can be set and modified by authorized professionals. When the stop operation command is issued through voice or button, all cable pulling mechanisms 1 stop running at the same time;

[0095] The cable laying process control is based on the existing smart construction site system 7 at the construction site and the specific vertical lifting plan, specific process control procedures, key safety monitoring measures and various parameters required for vertical lifting of large-section cables 4 formed on the smart construction site system, as well as external resources obtained through information exchange with the smart construction site system 7; the cable laying process control is also based on the real-time monitoring and process confirmation of the cable laying process by the operating personnel through the video and safety monitoring organization 6 and the smart construction site system 7; the process confirmation content includes not only the video and safety monitoring organization 6's control content for the cable vertical lifting process, but also includes the cable laying facilities involved in the video and safety monitoring organization 6 itself and the safety content involved in the cable laying process.

[0096] The voice information exchange warning service function of the information exchange warning service unit 64 is based on the information resources of the microprocessor control processing unit 61, the video and safety monitoring unit 62, the cable synchronous vertical traction protection unit 63 and the construction site smart site system 7. The handheld mobile terminal management module 641 and the computer management module 642 are video human-computer interaction terminals and can realize video and safety monitoring system process monitoring, parameter display, parameter over-limit alarm, authorized start and stop cable traction control, voice information exchange and other functions.

[0097] It should be noted that one of the main purposes of the present invention is to improve the application of the steel wire rope 2 traction and lifting laying technology in the vertical lifting of large-section cables 4 in high-rise buildings, and to use the advantage of the large allowable traction force of the core of the large-section cable 4 to reduce the workload of connecting the auxiliary steel wire rope 24 and the cable, and to improve the connection method of the auxiliary steel wire rope 24 and the cable in terms of quick connection; the large-section cable is directly lifted vertically in the electrical shaft at one time instead of adopting the process of switching the traction fixing point of the high-rise electric winch 11 traction wire rope to the bottom of the cable for a certain length and then lifting it vertically, avoiding the problem of excessive lateral pressure on the large-section cable when the cable is directly passed through the cable steering roller and pulled and laid to the high-rise horizontal laying channel after vertical lifting in the electrical shaft.

[0098] Another purpose of the present invention is to overcome the defects in the existing safety monitoring of the vertical lifting process of large-section cables 4 in high-rise buildings, and to provide a new structure of synchronous control safety monitoring system for vertically lifting large-section cables 4. The technical problem to be improved is to make the process of vertically lifting large-section cables more efficient, the vertical lifting process safer and more reliable, and avoid the occurrence of dangerous accidents, so as to be more suitable for practical use.

[0099] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be encompassed by the scope of the pending claims.

At the same time, remove the corresponding binding mechanisms for connecting the auxiliary steel wire rope to the cable outer sheath, the auxiliary steel wire rope, and the traction steel wire ropes of the middle-level and low-level electric winches; Step 8. When the large-section cable 4 is fixed in a wave shape to the main equipment layer of the high-rise building, the high-rise electric winch lowers the remaining large-section cable to the main equipment layer and removes the traction wire rope from the cable traction head. The cable is then guided by the operator and pulled by the cable conveyor to horizontally lay the cable on the main equipment layer.

3. The control method according to claim 1, wherein: The process control of the cable pulling and laying includes: Step 1. Before laying the cable, confirm the specific vertical lifting plan, specific process control procedures, and actual on-site compliance. If there are any discrepancies, make corrections in a timely manner or modify the plan or process control procedures according to existing procedures. Step 2. Lay out related facilities for vertical lifting of large-section cables according to the specific vertical lifting plan, conduct corresponding inspections, confirmations, and operations. Simultaneously, deploy corresponding video and safety monitoring systems and confirm relevant control parameters and key safety monitoring measures. Step 3. The vertical lifting process of large-section cables is controlled by the cable synchronous traction protection unit of the video and safety monitoring organization and the operating personnel responsible for real-time monitoring according to the specific process control procedures. When there is a set parameter alarm or a dangerous process status during the vertical lifting process of large-section cables, the cable synchronous traction protection unit or the operating personnel responsible for real-time monitoring will promptly issue an alarm or perform a hazard elimination operation. When the set protection parameters are reached or danger is about to occur, the cable synchronous traction protection unit or the operating personnel responsible for real-time monitoring will stop the traction protection operation.
