Technical Field

[0001] The invention relates to the technical field of equipment transportation, and in particular to a method for transporting and hoisting a precision instrument. Background Art

[0002] Precision instruments refer to equipment and devices or special industrial devices used to generate and measure precision quantities, including the observation, monitoring, determination, verification, recording, transmission, transformation, display, analysis, processing and control of precision quantities. The precision instruments in precision laboratories are generally heavy, have strict environmental requirements, require precise installation and positioning, and have strict vibration requirements.

[0003] Due to the above reasons, traditional precision instruments are placed underground, especially under constant temperature and humidity conditions and to prevent various interferences (such as vibration, electromagnetic, radiation, etc.). This poses a problem for the transportation and lifting of the precision instruments, and thus it is impossible to guarantee the effectiveness of the precision instruments in these links, and it is impossible to maximize the satisfaction of the precision instruments themselves from being damaged and affecting their functions; therefore, it does not meet the existing needs, and the present invention proposes a method for transporting and lifting precision instruments. Summary of the invention

[0004] The purpose of the present invention is to provide a method for transporting and hoisting precision instruments. Through virtual transportation route planning using BIM technology, transportation by transport vehicles, and integration of various monitoring and testing technologies and automated hoisting, the smooth transportation and hoisting of precision instruments from the factory to the installation site are achieved. During transportation, the upper structure of the vibration isolation frame is adjusted according to the shaking amplitude of the transport vehicle during driving to ensure its horizontal state. After being transported to the designated hoisting hole, the vibration isolation frame and the precision instruments are lowered to a horizontal towing platform using hoisting auxiliary facilities. The vibration isolation frame and the precision instruments are horizontally towed to the installation level together with the horizontal towing platform and smoothly landed on the foundation. The horizontal towing platform can then be dismantled, thereby solving the problems raised in the above-mentioned background technology.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the existing precision instruments in constant temperature and humidity conditions and to prevent various interference situations, precision instruments are usually placed underground, which brings difficulties to the transportation and lifting of precision instruments, thus failing to guarantee the effectiveness of precision instruments in these links and failing to maximize the technical problems of not damaging the precision instruments themselves and affecting their functions. Figure 1-Figure 8 , this embodiment provides the following technical solutions: A method for transporting and hoisting a precision instrument, comprising a vibration-isolating frame, the vibration-isolating frame being composed of a lower frame 1 and an upper frame 2, the vibration-isolating frame being divided into an upper and lower two-layer structure by the lower frame 1 and the upper frame 2, the vibration-isolating frame being used to be placed on a transport vehicle and later hoisting and towing equipment, an active buffer device 5 being arranged on the transport vehicle, the precision instrument being placed on the upper frame 2 of the vibration-isolating frame, and the precision instrument and the vibration-isolating frame being tied together by a rope tightener, a precision vibration-isolating device 3 and a vibration detection device being arranged between the lower frame 1 and the upper frame 2, and a general buffer device 17 being arranged between the vibration-isolating frame and the precision instrument; The method for transporting and hoisting the precision instrument comprises the following steps: Step 1: Use drone mapping and reconnaissance technology to obtain a scene layout diagram of the location where the precision instrument is installed, analyze different transportation routes based on the obtained scene layout diagram and select the best one; Step 2: Use BIM technology to build a BIM model for virtual transportation simulation to find problems that may occur when transporting precision instruments to the installation site; Step 3: Simulate the equipment transportation, perform finite element force calculation on the load of the vibration isolation frame, determine the key monitoring points during the transportation of the model and the real equipment, and determine the form of the vibration isolation frame and the location of the reinforcement points; Further simulation is performed to predict the acceleration, impact force, balance, etc., and deformation of the vibration isolation frame to which the equipment is subjected during transportation. The most unfavorable value is set according to the road section where the maximum value occurs in the simulation. That is, the most unfavorable situation is obtained for setting, and the standard value is compared for optimization. If it is not satisfied, continue with the above steps to optimize the vibration isolation structure and transportation route. It should be noted that the simulation of equipment transportation can perform finite element force calculation on the load of the vibration isolation frame, so as to determine the form of the vibration isolation frame and the location of the reinforcement points. According to the above finite element analysis results and the deformation of the vibration isolation frame under load, the maximum stress-bearing part of the vibration isolation frame is reinforced with a hoop and repeatedly tied. The precision instrument is tied to the vibration isolation frame with steel wire rope and rigging turnbuckles. The steel wire rope should be tied in an eight-shaped shape. The embodiment of the finite element force calculation process can be summarized into the following steps, and the corresponding calculation formula is given: First, the geometric model of the vibration mount needs to be established and divided into finite element meshes (such as quadrilateral or triangular elements). This step is the basis of finite element analysis. Material properties such as Young's modulus 𝐸 and Poisson's ratio 𝜈 are specified for each element. For each element, a local stiffness matrix Ke is established based on its material properties and geometry. Then, the local stiffness matrices of all elements are assembled into a global stiffness matrix K.

[0022] Where B is the shape function matrix and D is the elastic matrix of the material. Apply nodal loads and boundary conditions, such as fixed constraints or application of forces.

[0023] Use appropriate numerical methods to solve the linear equation system 𝐾𝑢=𝐹, where u is the nodal displacement vector and F is the nodal load vector. Calculate the stress and strain of each element based on the nodal displacement. Perform post-processing analysis to evaluate the response of the structure, such as stress distribution, deformation, etc., and determine the location of reinforcement points.

[0024] Assuming that the vibration-isolating frame is simplified to a two-dimensional plane problem, consider a quadrilateral element, and its local stiffness matrix Ke can be expressed as: h is the thickness of the element. Where E is Young's modulus and ν is Poisson's ratio.

[0025] Method for selecting reinforcement point location: 1. Stress concentration analysis: Determine the stress concentration area through finite element analysis; 2. Deformation assessment: assess the deformation of the vibration isolation frame under load and determine the area with the largest deformation; 3. Experience judgment: select the location of the reinforcement point based on engineering experience and expert opinions; 4. Structural symmetry: Consider the symmetry of the structure and distribute the reinforcement points reasonably; In the embodiment, the above formula and method may need to be adjusted according to the specific shape and load conditions of the vibration isolation frame. The actual finite element analysis usually needs to be completed using professional software; Step 4: According to the simulation results, select the corresponding position where the most unfavorable value of the equipment model occurs to install the gravity acceleration test instrument and the test instrument, and use a model with a 1:1 size and weight to the equipment to conduct pre-transportation on key sections, and conduct experimental monitoring to see whether the various parameter requirements during transportation are met; Step 5: If there are no problems in the above steps 1 to 4, the precision instrument is loaded on the vehicle and monitored during transportation according to the requirements of steps 1 to 4. The monitoring data can be linked to the alarm system on the vehicle. If a certain parameter is near the set threshold range, an early warning can be achieved. The technicians following the vehicle will troubleshoot the problem. A road monitor 4 is set at the front of the vehicle, combined with an active buffer device 5, to form data association with the rear. Step 6: Transport to the designated lifting hole. A small truck crane is needed to enter the workshop and transport to the vicinity of the lifting hole by a small truck crane; Step 7: Use the lifting auxiliary facilities in the workshop to lift downwards in the hole. The lifting auxiliary facilities include an intelligent track system and a hanging basket 7. The lifting auxiliary facilities perform the downward lifting work through the cooperation of the intelligent track system and the hanging basket 7. During the downward lifting process, the vibration-proof frame and the precision instrument are lifted downwards together; Step 8: Hang down to the bottom, where a horizontal towing platform 9 is provided, and the vibration-proof frame and the precision instrument are horizontally towed together through the horizontal towing platform 9; Step nine: Arrive at the installation level, temporarily fix the precision instrument on the horizontal towing platform 9, remove the hanging basket 7 and the vertical transport platform where the precision instrument and the vibration isolation frame are located, transport it through the dedicated horizontal towing platform 9, transport it to the foundation position, retract the horizontal towing platform 9 pillars, and the precision instrument together with the vibration isolation frame arrives at the foundation. Before installation, remove the vibration isolation frame and protective measures, then connect the bolts of the precision instrument and the foundation to install the precision instrument. After the installation is completed, remove the horizontal towing platform 9.

[0026] In step 1, the transportation route is selected by selecting the best method, which includes the following: An acquisition module is used to acquire a scene layout diagram of the location where the precision instrument is installed by using drone mapping and reconnaissance technology; An analysis module is used to analyze the scene layout diagram based on the acquired scene layout diagram, so as to analyze different transportation routes; The selection module is used to select the best of the different transportation routes that have been analyzed, so as to determine the optimal transportation route for precision instruments and whether to carry out temporary widening, repairing, slope reduction, greening removal and restoration of the road; Among them, the selection module includes: The optimal route determination module determines the transportation route according to the pre-set optimal route standard, thereby determining the optimal transportation route; The optimal route standard has three points, namely safety standard, economic standard and distance standard. The optimal route determination module will compare the different transportation routes analyzed with the optimal route standards one by one. Only those that fully meet the optimal route standards can be determined as the optimal transportation route by the optimal route determination module; If the optimal transport route cannot be determined for all routes, the scene layout diagram is re-acquired and analyzed, and different transport routes are re-analyzed to re-determine the optimal transport route.

[0027] It should be noted that: the safety standard is first based on safety considerations, and bumps and slopes need to be avoided as much as possible; the economic standard, secondly, considers economic rationality, and needs to avoid affecting the buildings, roads and greenery on the transportation route as much as possible; the distance standard, finally considers the length of the route, and needs to choose the shortest distance along the way as much as possible.

[0028] Specifically, before conducting a virtual simulation, the acquisition module first uses drone mapping and reconnaissance technology to obtain the scene layout diagram of the location where the precision instrument is installed, and then analyzes the scene layout diagram through the analysis module to analyze different transportation routes. Finally, the selection module selects the best of the analyzed different transportation routes through the optimal route determination module to determine the optimal transportation route for the precision instrument. The optimal transportation route determined by the optimal route determination module needs to meet the optimal route standard. The optimal route determination module compares the analyzed different transportation routes with the optimal route standard one by one. Only the transportation route that fully meets the three-point standard can be determined as the optimal transportation route by the optimal route determination module.

[0029] Step 4. During the test, the same vibration-isolating frame as that used in actual transportation is used. The speed of the transport vehicle is magnified to 40 km / h. Before the test, the most unfavorable 5-kilometer section of the transport route is selected for testing. The impact acceleration tester is selected as the measuring instrument based on the transportation requirements of the precision instrument. At least three monitoring points are arranged at the center of the upper shell of the instrument model, the end, and the center of the frame of the tail structure.

[0030] Specifically, in order to monitor the impact acceleration condition on the vibration isolation frame during the transportation of equipment, a model with the same weight as the actual equipment is used before transportation, that is, the same structural shell is used, and each internal section is equipped with counterweight blocks of equal weight for testing, and measuring instruments are arranged at three monitoring points in the center of the upper shell of the instrument model, the end and the center of the frame of the tail structure. During the test, the same vibration isolation frame as the actual transportation is used, and the driving speed of the transport vehicle needs to be deliberately increased to 40 kilometers per hour. Before the test, the transport vehicle will select the most unfavorable 5-kilometer section on the transport route for testing, so as to monitor whether various parameter requirements during transportation are met, which provides a reference for measuring various parameters in transportation and ensuring transportation effects.

It is linked with the road monitoring device 4 through the active buffer device 5 to respond to the change of the tilt angle of the transport vehicle in real time and automatically adjust the working state of the hydraulic cylinder. It can adjust the posture of the upper structure of the vibration-isolating frame according to the shaking amplitude of the transport vehicle during driving to maintain the horizontal state of the vibration-isolating frame and the precision instrument, thereby further ensuring that the acceleration value of ground transportation meets the vibration isolation requirement of precision instrument transportation.

[0033] The active buffer device 5 comprises: Hydraulic cylinders, hydraulic cylinders are provided at the four corners of the loading plate 6; An active buffer balancing system is used to integrate an active buffer balancing system in the active buffer device 5, which responds to the change of the tilt angle of the transport vehicle in real time and automatically adjusts the working state of the hydraulic cylinder to maintain the horizontal state of the vibration-proof frame and the precision instrument; The road monitoring device 4 is used to work in conjunction with the active buffer balancing system.

Four workers are arranged to ride and follow during the driving process, and spot-check the tightness of the locks at any time for timely reinforcement. To prevent sudden parking along the way, one engineering vehicle is used to lead the way, and another engineering vehicle follows to provide protection, and other communication and official vehicles follow to ensure the stability and safety of the transportation.

[0043] Lifting auxiliary facilities, including: Intelligent track system, temporary tracks 8 are installed on both sides of the lifting hole channel. Tracks 8 are specially designed for lifting operations and have sufficient bearing capacity and stability; The lifting device is composed of a worm gear assembly 18 and a screw rod 19.

In addition, a variety of sensors are integrated in the hanging basket 7 and the track 8 to monitor the position, speed and tilt state of the hanging basket 7 in real time. The intelligent control system collects sensor data for real-time analysis and adjusts the operating state of the hanging basket 7 according to the analysis results; The operation interface provides an intuitive user operation interface for the operator, displays the real-time status and system parameters of the hanging basket 7, and allows the operator to perform manual control mode or switch to automatic control mode; Safety monitoring and alarm system, which continuously monitors the safety of lifting operations and issues warnings immediately if any abnormality is detected. When the safety monitoring and alarm system detects potential danger, it automatically initiates emergency response procedures, including emergency stop; The precise control system for hoisting operations can achieve precise positioning of the hanging basket 7 through the intelligent control system, ensuring that the precision instruments can accurately reach the predetermined installation position; The descent speed fine-tuning system fine-tunes the descent speed of the hanging basket 7 according to the real-time monitoring data to achieve a smooth and uniform hoisting operation.

[0044] The hoisting auxiliary facility also includes an electric motor 10 and a steel wire rope 11. The electric motor 10 is located above the hanging basket 7. The steel wire rope 11 is arranged below the electric motor 10. The other end of the steel wire rope 11 away from the electric motor 10 is connected to the hanging basket 7. The vertical lifting of the hanging basket 7 is achieved by the electric motor 10 and the steel wire rope 11. Among them, the hanging basket 7 and the track 8 are vertically hoisted through a lifting device. The hanging basket 7 is spliced ​​by various channel steels with holes. The hanging basket 7 is detachable through the splicing of channel steels, and the hanging basket 7 is hollow. The hanging basket 7 holds the precision instrument through the four corners. The precision instrument is provided with bolt holes, and the precision instrument is connected to the hanging basket 7 through the bolt holes.

[0045] It should be noted that a small automobile crane is required to transport the precision instrument to the designated lifting hole and enter the workshop. The instrument is hoisted and transported to the vicinity of the lifting hole together with the vibration-proof frame and the auxiliary vibration-proof measures, and then the lifting auxiliary facilities are used for the lowering work. The precision instrument is placed in the hanging basket 7. The lifting device is composed of a worm gear assembly 18 and a screw rod 19. When the motor installed on the outside of the worm gear assembly 18 is started, the motor transmits power to the worm gear assembly 18, and the worm gear assembly 18 then transmits power to the screw rod 19, so that the screw rod 19 is lifted and lowered, so that the track 8 can carry the precision instrument in the hanging basket 7 for vertical lifting through the lifting device, and the hanging basket 7 is hollow, which can facilitate the connection between the hanging basket 7 and the horizontal towing platform 9. The hanging basket 7 is hollow and can tow the precision instrument through the four corners. Bolt holes are provided on the precision instrument, which can be conveniently connected to the hanging basket 7 and the horizontal towing platform 9. Various types of perforated channel steels can be used for splicing and can be disassembled at any time. The vertical movement of the lifting auxiliary facilities is achieved through an integrated lifting device. The lifting system is realized by the installation system, which consists of an electric motor 10 and a wire rope 11. The electric motor 10 and the wire rope 11 can accurately control the lifting speed and position of the hanging basket 7. In addition, the lifting platform is also equipped with an advanced balancing system. Through the various sensors on the hanging basket 7 and the track 8, the inclination angle and position of the hanging basket 7 are monitored in real time, so that the tension of the wire rope 11 can be automatically adjusted to ensure that the precision instrument remains horizontal during the vertical movement. After the precision instrument reaches the installation level, the precision instrument is temporarily fixed on the horizontal towing platform 9, and then the hanging basket 7 is removed. Since the hanging basket 7 is spliced ​​by various types of perforated channel steels, it only needs to be removed on all sides when it is removed. After the hanging basket 7 is released from the vibration isolation frame, the precision instrument area can be evacuated from the top as a whole. The hanging basket 7 can not only lift the precision instrument, but also protect the precision equipment on all sides. In addition, in case someone stands on the hanging basket 7 to operate during vertical lifting, the fence around the hanging basket 7 can facilitate the fixing of the safety rope.

[0046] The horizontal towing platform 9 includes a hydraulic system, a flat panel support 12, a lifting column 13, a universal wheel 14 and an active hydraulic support system 15. The active hydraulic support system 15 is installed at four corners above the flat panel support 12. The active hydraulic support system 15 is composed of one or more hydraulic cylinders, a hydraulic pump, a control valve and an oil tank. The hollow area on the flat panel support 12 is used to accommodate precision instruments suspended from the hanging basket 7. Lifting columns 13 are arranged at the four corners below the flat panel support 12, and universal wheels 14 are arranged at the other end of the lifting columns 13.

[0047] The horizontal towing platform 9 is constructed of high-strength steel and has excellent load-bearing capacity and stability. The size and shape of the horizontal towing platform 9 are tailored according to the specific specifications of the precision instrument to ensure that the instrument and the vibration-isolating frame can be accurately placed on the horizontal towing platform 9. The middle position of the flat panel bracket 12 is a hollow area, and the hollow area is used to accommodate the bottom structure of the precision instrument (the bottom structure of the precision instrument is a base, and the base can also be used as a connecting part of the bottom of the precision instrument, and the connecting part is usually used to connect with the anchor bolts of the foundation, etc.). The flat panel bracket 12 is divided into front and rear parts, and a lock 16 is provided at the seam of the flat panel bracket 12. The front and rear parts of the flat panel bracket 12 are spliced ​​by the lock 16.

[0048] The horizontal hauling platform 9 specifically performs the following operations: The hanging basket 7 and the track 8 are driven by the lifting device to vertically hang the vibration-proof frame and the precision instrument to the horizontal towing platform 9. After the vibration-proof frame and the precision instrument are temporarily fixed on the horizontal towing platform 9, the hanging basket 7 where the precision instrument and the vibration-proof frame are located is removed; The precision instrument and the vibration-proof frame are transported by a dedicated horizontal hauling platform 9, and the horizontal hauling platform 9 horizontally hauls the precision instrument and the vibration-proof frame to the base position; The lifting column 13 of the horizontal hauling platform 9 is retracted, and the precision instrument and the vibration-proof frame are brought to the foundation. The precision instrument and the vibration-proof frame are smoothly dropped on the foundation, and the bolts of the precision instrument and the foundation are connected to fix the precision instrument and the vibration-proof frame on the foundation. The lock buckle 16 is removed to separate the front and rear parts of the flat panel support 12, and the horizontal towing platform 9 is removed to complete the horizontal towing of the precision instrument.

[0049] Specifically, after the precision instrument reaches the foundation for unloading, the next task is to unload the lifting buckle. The operator must be very careful when performing this step to ensure that no impact or vibration is caused to the precision instrument. First, the operator will check the status of the lifting buckle to confirm that it is well fixed and not damaged. Then, the operator will slowly loosen the lifting buckle and gradually transfer the weight of the instrument and the vibration-proof frame to the horizontal towing platform 9. During the unloading process, the status of the precision instrument will be fed back in real time to ensure that the precision instrument remains horizontal and stable during the entire unloading process. The operator will use professional tools, such as torque wrenches and special unlocking devices, to operate the unlocking and separation of the lifting buckle. Once the lifting buckle is completely removed, the operator will fix the precision instrument and the vibration-proof frame, and use the preset fixing points and fasteners on the horizontal towing platform 9 to ensure the stability of the precision instrument during subsequent transportation. The uniform lifting of precision instruments is a key step, and the hydraulic system integrated on the lifting platform is responsible for achieving this function. The hydraulic system consists of one or more hydraulic cylinders, hydraulic pumps, control valves and oil tanks, which can provide stable and adjustable lifting force. The operator controls the hydraulic system through buttons and knobs on the control panel to achieve precise control of the lifting speed of precision instruments. The hydraulic system is designed with a fine-tuning function, allowing operators to lift precision instruments at a very slow speed (no more than 5cm / min) at a uniform speed to ensure that there will be no adverse effects on the precision instruments during the lifting process. When the precision instruments rise to a height of 1.5m, the built-in sensors in the hydraulic system will monitor the lifting speed and height in real time. , ensuring that the equipment moves accurately along the predetermined trajectory. In addition, the hydraulic system is also equipped with an overload protection device. Once an abnormal load is detected, the system will automatically stop working and sound an alarm to prevent equipment damage or operating accidents. In addition, the horizontal towing platform 9 also has an emergency stop function, which is essential in case of emergency or when it is necessary to quickly stop the movement of precision instruments. The emergency stop system consists of one or more emergency stop buttons. The operator can quickly trigger the system at any position to immediately cut off the power supply of the hydraulic system and stop all actions. The design of the horizontal towing platform 9 also takes into account the comfort and convenience of the operator. The control panel is designed to be intuitive and easy to use. All control buttons and knobs are clearly marked to ensure that operators can operate quickly and accurately even in a tense working environment. After the bottom of the precision instrument and the vibration-proof frame enter the horizontal towing platform 9, the operator will use the fixing devices on the horizontal towing platform 9 to firmly fix the equipment on the horizontal towing platform 9. These fixing devices can be adjusted according to the size and shape of the bottom feet or vibration-proof frames of the precision instrument to ensure the stability of the precision instrument during transportation. Subsequently, the operator will start the hydraulic system of the horizontal towing platform 9 to lift the precision instrument to the required height in preparation for horizontal towing. During the horizontal towing process, the operator will closely The stability of the precision instrument and the operating status of the horizontal hauling platform 9 are closely monitored to ensure the safety and smoothness of the horizontal hauling process. After arriving at the destination, the operator will use the hydraulic system of the horizontal hauling platform 9 to smoothly lower the precision instrument to the foundation. After the precision instrument is in place, the operator will release the fixing device on the horizontal hauling platform 9 to complete the final positioning of the precision instrument. The design and application of the horizontal hauling platform 9 greatly improves the efficiency and safety of the transportation of precision instruments. At the same time, its emergency stop and universal movement functions provide additional safety guarantees for the operators. Through the implementation of the above scheme, the transportation of precision instruments becomes simpler, faster and more reliable. After the precision instrument is safely lifted to the predetermined height, the next task is to remove the hanging basket 7. The hanging basket 7 is a structure used to additionally fix the precision instrument during the vertical lifting process. It is no longer needed after the precision instrument reaches the ground. The operator needs to be extra careful when removing the hanging basket 7 to prevent any damage to the precision instrument or the horizontal hauling platform 9. First, the operator checks the fixing status of the hanging basket 7 to ensure that all connection points have been unlocked. Then, the operator will use professional tools such as wrenches and lifting equipment to gradually remove the various parts of the hanging basket 7. During the removal process, the operator needs to pay close attention to the stability of the precision instrument to ensure that the precision instrument is still safely fixed on the horizontal hauling platform 9 after the hanging basket 7 is removed. Once the hanging basket 7 is completely removed, the operator will conduct a final check on the fixing status of the precision instrument to ensure that there is no sign of looseness or instability. In addition, the operator also needs to clean up any debris or debris left after the removal of the hanging basket 7 to ensure the smooth transportation path; The operating interface design of the horizontal hauling platform 9 focuses on user experience and ease of operation, and provides an intuitive and easy-to-understand control panel. The control panel integrates all necessary control buttons and indicator lights to ensure that operators can quickly master the use of the method. The display screen on the control panel can provide real-time information about the status of the horizontal hauling platform 9, such as current height, load, battery power, etc., so that operators can monitor the working status of the horizontal hauling platform 9 at any time. The emergency stop function is a key safety feature in the design of the horizontal hauling platform 9. There is a striking red emergency stop button on the control panel. Once the button is pressed, it will immediately cut off all power supply and stop all mechanical actions, including the operation of the hydraulic system, to ensure that the operation can be stopped quickly and safely in an emergency. In addition, the horizontal hauling platform 9 is also equipped with an emergency braking system that can detect any abnormal situation and stop the operation quickly and safely. In case of an over-high pressure in the hydraulic system or a jammed universal wheel 14, an emergency stop is automatically triggered. The bottom of the horizontal towing platform 9 is equipped with 4 to 8 universal wheels 14. The horizontal towing platform 9 is a key device for horizontal towing of precision instruments. The height of these universal wheels 14 is less than 5 cm, ensuring that the overall height is lower than the foundation to avoid collisions during transportation. The universal wheels 14 of the horizontal towing platform 9 are designed to allow flexible movement in narrow or tortuous spaces while maintaining stable load-bearing performance. Each horizontal towing platform 9 is equipped with precision bearings to ensure stability, low noise and low friction during movement, and reduce damage to the ground during transportation. In addition, the universal wheels 14 of the horizontal towing platform 9 also have a locking function. The locking mechanism of the universal wheels 14 allows the wheels to be fixed when necessary, ensuring that the horizontal towing platform 9 can stably carry precision instruments on uneven ground and prevent the precision instruments from sliding. The structural design of the horizontal hauling platform 9 is the key to ensure its stability and durability. The universal wheels 14 at the bottom of the horizontal hauling platform 9 are connected to the "mouth"-shaped steel flat panel bracket 12 through a strong lifting column 13. The support rod is made of high-strength alloy material, and the surface is specially treated to enhance wear resistance and corrosion resistance. The number of universal wheels 14 is designed according to the load-bearing requirements of the horizontal hauling platform 9 to ensure that it can maintain balance and stability even when fully loaded. The design of the "mouth"-shaped steel flat panel bracket 12 fully considers the horizontal hauling requirements of precision instruments. The internal hollow design of the flat panel bracket 12 allows the precision instruments to be directly aligned and placed on the foundation when lowered. This design significantly improves the accuracy and efficiency of positioning precision instruments. Sufficient space is left around the flat panel bracket 12 to accommodate equipment of different sizes and provide good compatibility. The flat panel bracket 12 is welded with I-beams, which are widely used in engineering structures for their excellent bending resistance and stability. High-standard welding technology is used in the welding process to ensure the structural integrity and durability of the flat panel bracket 12. The welding points are strictly quality tested to ensure that there are no cracks or defects. In the precision instrument transportation and hoisting method of the present invention, in order to further improve the stability and safety of the transportation process, we specifically propose that all underground hauling operations should be uniformly carried out using a dedicated hauling vehicle. This dedicated hauling vehicle is designed to meet the specific requirements of precision instruments, ensuring a smooth hauling experience throughout the transportation process, and avoiding any shock or vibration that may be caused by traditional handling methods, which may adversely affect the accuracy and performance of the precision instruments.

[0050] In addition, this method recommends operating with the vibration isolation frame during the entire process of lifting, handling and installation. The vibration isolation frame is not only a temporary structure during transportation, but is also recommended as a permanent component of the precision instrument. This design allows the vibration isolation frame to provide continuous vibration isolation and protection throughout the entire life cycle of the instrument. The permanent design of the vibration isolation frame means that it can be reused during the installation, use and maintenance of the precision instrument, thereby reducing additional loading and unloading and adjustment work, while also improving overall transportation efficiency.

[0051] By using a special haulage vehicle and a vibration-proof frame as a permanent structure for precision instruments, the transportation and hoisting method of the present invention ensures safe transportation of precision instruments while also improving the convenience and economy of operation. This comprehensive solution provides a more reliable and efficient option for the transportation of precision instruments.

[0052] In addition, the horizontal hauling platform 9 also integrates advanced obstacle avoidance technology, similar to the mature technology used by common express delivery robots in hotels. The platform is equipped with multiple sensors and cameras, which can monitor the surrounding environment in real time, automatically detect and avoid obstacles in the traveling path. This intelligent obstacle avoidance function ensures that in complex or crowded working environments, the platform 9 can safely and efficiently carry out the hauling work of precision instruments without additional intervention by the operator. Since this is a mature technology widely used in multiple fields, no further detailed description will be provided here.

[0053] Above the "mouth"-shaped steel flat bracket 12, the active hydraulic support system 15 is precisely installed at the four corners to form a stable support structure. The design of the active hydraulic support system 15 fully considers the force distribution and load-bearing requirements to ensure smooth and uniform support during lifting and lowering. The active hydraulic support system 15 consists of a set of hydraulic cylinders, hydraulic pumps, control valves, and oil tanks. Through precise mechanical design, the hydraulic cylinders can withstand all the forces generated by the horizontal hauling platform 9 during lifting. The hydraulic pumps and control valves work together to precisely control the flow of hydraulic oil to achieve precise control of the hydraulic cylinders. The operator can control the lifting and lowering of the active hydraulic support system 15 through the buttons on the control panel. The control panel is provided with clear instructions to guide the operator on how to operate. The active hydraulic support system 15 is also equipped with a safety valve to prevent system overload and ensure that the design load-bearing capacity of the active hydraulic support system 15 will never be exceeded at any time; The fixation of precision instruments is a crucial step to ensure their safety during horizontal transportation. Above the "mouth"-shaped steel flat bracket 12, a series of standardized bolt holes are designed. The positions and sizes of these bolt holes are precisely matched according to the feet or fixing points of the vibration isolation brackets of the precision instruments. Operators will use special bolts and fasteners to firmly fix the feet or vibration isolation brackets of the precision instruments to the horizontal transportation platform 9 through the bolt holes. The fasteners are made of high-strength materials, which can ensure that they will not loosen or be damaged during horizontal transportation. The design of the bolt holes allows for quick adjustment and fixation, enabling operators to rapidly fix the equipment to the horizontal transportation platform 9. To avoid damaging the precision instruments during the fixation process, all bolts and fasteners have undergone special surface treatment to reduce friction and provide good clamping force. In addition, protective devices are designed around the bolt holes to prevent scratches or impacts on the surface of the precision instruments during fixation and horizontal transportation. The final positioning of the precision instruments is a crucial step to ensure their accurate installation at the predetermined position. After the precision instruments are transported to the designated location, operators will use the active hydraulic support system 15 on the horizontal transportation platform 9 to smoothly lower the precision instruments to the height of the foundation. Operators will first check the flatness and stability of the foundation to ensure that it can bear the weight of the precision instruments and the forces that may be generated during operation. Then, operators will slowly operate the active hydraulic support system 15 to lower the precision instruments to an appropriate height above the foundation, ensuring that the precision instruments can accurately align with the marks on the installation position. During the lowering process of the precision instruments, operators will closely monitor the stability and alignment of the precision instruments to ensure that they do not deviate from the predetermined position. Once the precision instruments reach the final position, operators will use fixing devices to firmly fix the true fixing feet of the precision instruments to the foundation. These fixing devices can be bolts, clamps, or other fixing tools suitable for the feet of the precision instruments. After the precision instruments are fixed, operators will conduct a final inspection to ensure that all fixing devices have been correctly installed and the precision instruments are in a horizontal state. In addition, operators will also check the electrical connections and pipeline connections of the precision instruments to ensure that there is no damage or looseness during transportation. After the final positioning is completed, operators will conduct a startup test of the precision instruments to ensure that the precision instruments have not been damaged during transportation and positioning and can operate normally. The test includes checking each component of the precision instruments to confirm whether they are working properly, and testing the performance of the precision instruments to ensure that they reach the expected working state.

[0054] Working principle: Through virtual simulation transportation combined with BIM technology, various problems that affect transportation and lifting can be discovered before transportation, effectively ensuring the efficiency and safety of transportation, and simulating the transportation of equipment. Finite element force calculations can be performed on the load-bearing of the vibration isolation frame, so that the form of the vibration isolation frame and the location of the reinforcement points can be determined. During transportation, the active buffer device 5 can adjust the posture of the upper structure of the vibration isolation frame according to the shaking amplitude of the transport vehicle during driving to ensure its horizontal state. After transporting to the designated lifting hole, the vibration isolation frame and precision instruments are lowered to the horizontal towing platform 9 using lifting auxiliary facilities. After the precision instruments and vibration isolation frame are horizontally towed to the top of the foundation, the flat panel bracket 12 is lowered by the lifting column 13, so that the precision instruments of the equipment and the vibration isolation frame can be smoothly placed on the foundation together. After that, the lock buckle 16 can be removed to split the flat panel bracket 12 front and back and remove it, thereby completing the horizontal towing of the precision instruments.
