Abstract

This invention discloses an installation and positioning method for an underground vertical circulation parking system. First, the front frame assembly and rear frame assembly, integrating a large circulating chain and sprocket set, are pre-assembled on the ground. The two assemblies are then sequentially hoisted into the underground shaft and initially fixed to the bottom embedded parts. The verticality of the frames and the relative distance between them are adjusted to a preset accuracy using a positioning adjustment device at the shaft opening. Subsequently, connecting components and a synchronous drive shaft are installed to complete chain tensioning and synchronous operation debugging. Then, the two chains are driven to run intermittently synchronously, and all vehicle pallets are assembled sequentially at the shaft opening storage and retrieval station. Finally, the entire machine is debugged and installed. This method moves the core assembly process to the ground, relying on shaft opening adjustment to ensure installation accuracy, significantly reducing high-altitude underground operations, and effectively improving construction efficiency and safety.

Description

Technical Field

[0001] This invention relates to the field of automated parking equipment technology, and in particular to an installation method for an underground lifting-type vertical circulation automated parking system. Background Technology

[0002] Currently, most underground silo parking garages use vertical lifting parking systems. These systems require multiple steps, including lifting, lateral movement, and rotation, to access and retrieve vehicles. This process is cumbersome and inefficient. Furthermore, the complex structure and numerous types of components result in high equipment costs and high maintenance costs, leading to high overall construction costs per parking space and severely limiting the widespread adoption and development of underground silo parking garages.

[0003] Lift-type vertical circulation parking systems are a new type of parking equipment specifically adapted to underground shaft structures. They employ a bottom-supported, top-accessible structure, offering significant advantages over vertical lifting equipment, including simpler structure, higher operating efficiency, and lower manufacturing costs. However, as a new type of underground parking equipment, standardized and systematic installation methods are currently lacking. In practice, traditional assembly methods using disassembled components are often employed: workers must enter the underground shaft to assemble steel structures, transmission components, and guide components one by one. This involves numerous high-altitude operations within the confined space, resulting in high safety risks and low efficiency. Furthermore, the verticality, relative spacing, and coaxiality of the front and rear frames lack efficient and precise adjustment methods, making stable control of installation accuracy difficult. This can easily lead to asynchronous chain operation and vehicle pallet jamming, directly impacting equipment reliability and lifespan. Additionally, the overall process layout is unreasonable, with a large proportion of underground work, long construction cycles, and poor installation quality consistency.

[0004] In summary, the existing installation methods for underground lifting-type vertical circulation parking systems have drawbacks such as high safety risks, low installation accuracy, poor construction efficiency, and weak quality stability. Summary of the Invention

[0005] The purpose of this invention is to provide an installation method for an underground lifting-type vertical circulation multi-level parking system, so as to solve the above-mentioned technical problems existing in the prior art. The specific technical solution is as follows: An installation method for an underground lifting-type vertical circulation multi-level parking system, characterized by comprising the following steps: On the ground, a front frame assembly pre-installed with the first circulating chain and the first circulating sprocket group, and a rear frame assembly pre-installed with the second circulating chain and the second circulating sprocket group are assembled respectively. The front frame assembly and the rear frame assembly were hoisted into the underground shaft in sequence, and their bottoms were fixedly connected to the embedded parts at the bottom of the shaft. A positioning adjustment device is installed at the top of the wellbore. The verticality of the front frame assembly and the rear frame assembly, as well as their relative distance, are adjusted at the wellhead using the positioning adjustment device to achieve the preset installation accuracy. Install connecting components and synchronous drive shafts between the front frame assembly and the rear frame assembly, perform tensioning and adjustment on the first and second circulating chains, and complete the synchronous operation adjustment of the first and second circulating chains. The first and second circulating chains are driven to run intermittently and synchronously. At the vehicle retrieval station at the top of the shaft, the two ends of the vehicle pallet are successively installed and fixed to the corresponding first and second triangular support plates to complete the assembly of all vehicle pallets.

[0006] Furthermore, the specific steps for assembling the front frame assembly and the rear frame assembly on the ground are as follows: Assemble the front frame steel structure, assemble the drive and transmission system, the first circulating chain and the first triangular support plate on the front frame steel structure, and adjust the first bottom arc tensioning structure to pre-tension the first circulating chain to form the front frame assembly. After assembling the rear frame steel structure, the guide rail support structure, guide rail, second circulating chain and second triangular support plate are assembled on the rear frame steel structure. The second bottom arc tensioning structure is adjusted to pre-tension the second circulating chain to form the rear frame assembly.

[0007] Furthermore, the positioning adjustment device includes a mounting base connected to the wellhead embedded plate, a positioning base that cooperates with the top crossbeam of the frame, and positioning adjustment screws arranged in both directions along the front and rear and left and right sides. During adjustment, the horizontal position and verticality of the front frame assembly and the rear frame assembly are adjusted by turning the positioning adjustment screws until the preset installation accuracy requirements are met.

[0008] Furthermore, the connecting components are front and rear connecting rods. During installation, the horizontal and diagonal rods are assembled sequentially from the bottom of the well shaft upwards to connect the front frame assembly and the rear frame assembly into an integral load-bearing frame. After the connecting rods are installed, the first and second circulating chains are tensioned a second time.

[0009] Furthermore, before installing the synchronous drive shaft, the first circulating chain of the front frame assembly is driven at low speed by the drive and transmission system. The phase of the first circulating chain and the second circulating chain is adjusted so that the first triangular support plate and the second triangular support plate at the corresponding positions on the front and rear frames are coaxially aligned in the front-rear direction. Then, the synchronous drive shaft is assembled and the synchronous operation is debugged.

[0010] Furthermore, when installing the vehicle pallet, the electrical control system controls the first and second circulating chains to operate synchronously in opposite directions intermittently. The vehicle pallets are installed and fixed one by one onto the corresponding first and second triangular support plates in an alternating left-right sequence, so that the load on both sides of the frame remains balanced.

[0011] Furthermore, after all the vehicle pallets are assembled, the first bottom arc tensioning structure of the front frame assembly and the second bottom arc tensioning structure of the rear frame assembly are adjusted to perform a third tensioning on the first and second circulating chains, eliminating chain sag deviation under full load.

[0012] Furthermore, before performing the overall machine cycle operation debugging, the layout and wiring debugging of all position sensors are completed first. Then, the side parts of the front frame assembly and the rear frame assembly are anchored to the embedded parts of the well barrel sidewall. After confirming that the overall structure is stable, the positioning adjustment device at the top of the well barrel is removed.

[0013] Furthermore, after removing the positioning adjustment device, a telescopic protective plate assembly is installed at the opening at the top of the well shaft. The drive unit of the telescopic protective plate is connected to the equipment control system to complete the linkage and interlocking debugging of the opening and closing action of the protective plate and the cyclic operation of the equipment.

[0014] Furthermore, after the telescopic protective plate is successfully tested and adjusted, a vehicle access hall structure is installed on the top of the well shaft, and connected to the vehicle control system to perform a full-process vehicle storage and retrieval trial run and debugging. After passing the test, the equipment installation is completed.

[0015] The installation method of the underground lifting-type vertical circulation multi-level parking system of the present invention has the following advantages: 1. By adopting an integrated process path of pre-assembly of the ground assembly, overall hoisting into the well, precise adjustment at the wellhead, and top-level cyclic assembly, the core assembly work is transferred to the ground, significantly reducing the construction time underground. The wellhead positioning and adjustment device enables high-precision adjustment of the frame's verticality and relative spacing, eliminating the need for personnel to go deep underground for high-altitude alignment work, significantly reducing construction safety risks. Relying on the equipment's own cyclic function, the vehicle pallet is assembled sequentially at the wellhead, avoiding the difficulties of working in the confined space underground. Overall, this effectively improves the installation efficiency and positioning accuracy of parking equipment in underground wells, taking into account both construction safety and installation quality.

[0016] 2. The steel structure assembly of the front and rear frames, the assembly of the core transmission and guide components are completed on the ground, and the chain pre-tensioning is completed simultaneously. This can make full use of the open working conditions and tooling equipment on the ground, and improve the assembly accuracy of key components such as the drive system and guide rails. The pre-tensioning treatment can eliminate the initial assembly gap of the chain, avoid chain slippage and derailment during hoisting and transportation, and at the same time, move a large number of loose parts assembly work to the ground, further reducing the amount of underground work, and can flexibly adapt to different site construction conditions.

[0017] 3. The positioning and adjustment device, consisting of a mounting base, a positioning base, and a bidirectional adjusting screw, allows for precise bidirectional micro-adjustment of the horizontal and vertical positions of the frame at the wellhead by turning the screw. This method is convenient to operate and offers controllable adjustment accuracy. Using the initial fixed point at the bottom of the frame as a fulcrum, it eliminates the need for underground high-altitude operations, facilitating real-time monitoring and repeated corrections. It reliably ensures the parallelism and coaxiality of the front and rear frames, providing a reliable accuracy foundation for subsequent synchronous chain operation and precise alignment of the guide rails.

[0018] 4. By installing the front and rear connecting rods in a bottom-up sequence, and then assembling the horizontal and diagonal rods in sequence, the two sets of frames can be connected into an integral space truss structure, which effectively improves the overall torsional stiffness and bending performance of the structure and adapts to the dynamic load conditions during equipment operation. After the connecting rods are installed, the chains are tensioned a second time, which can eliminate the chain tension deviation caused by the change in the stress state after the frame is connected, ensure that the tension of the two sets of chains is consistent, and avoid problems such as asynchronous operation and uneven wear caused by uneven tension.

[0019] 5. Before assembling the synchronous drive shaft, adjust the phase of the front and rear circulating chains to ensure that the corresponding triangular support plates are coaxially aligned before installing and debugging the drive shaft. This avoids additional internal stress during the assembly process and prevents the drive shaft from being damaged by torsional fatigue and the chain from wearing unevenly during equipment operation. This ensures the synchronization accuracy and service life of the transmission system from the installation stage. At the same time, phase pre-alignment simplifies the subsequent synchronization debugging process, reduces the debugging difficulty, and improves the debugging efficiency.

[0020] 6. Driven by an electrical control system, the chain operates intermittently and synchronously in both directions, ensuring that the vehicle pallet assembly is always completed at the vehicle retrieval station at the wellhead. This eliminates the need for personnel to go down into the well for high-altitude installation work, resulting in high construction safety. The alternating left and right installation sequence ensures that the load on both sides of the frame remains balanced, avoiding frame deformation caused by continuous installation on one side. This guarantees structural stability and assembly accuracy during the installation process, laying the foundation for the subsequent stable operation of the equipment. Attached Figure Description

[0035] To better understand the purpose, structure, and function of this invention, the installation method of the underground lifting-type vertical circulation three-dimensional parking equipment of this invention will be described in detail below with reference to the accompanying drawings.

[0036] This invention provides an installation method for an underground lifting-type vertical circulation parking system 1. The parking system 1 is entirely housed within a reinforced concrete underground shaft 2. The shaft 2 can be circular or rectangular in cross-section according to the design, and is constructed using prefabrication or cast-in-place methods. The parking system 1 mainly includes a front frame steel structure 3, a rear frame steel structure 4, a circulating chain, triangular support plates, a vehicle carrier pallet 22, a drive and transmission system 6, and guide rail 15 components. The installation method in this embodiment adopts a holistic approach: pre-assembly of the ground assembly, overall hoisting into the shaft, precise adjustment at the shaft opening, and top-mounted circulating assembly. This method specifically addresses the problems of large workload, difficulty in ensuring positioning accuracy, and high construction safety risks associated with traditional underground component assembly.

[0037] Before formal installation, complete the preliminary preparations: confirm that all equipment components have been transported to the site, the civil structure construction of shaft 2 has been completed and passed the acceptance, the construction personnel, supporting tools and hoisting equipment required for installation are in place, and the on-site installation management procedures and safety assurance measures are in place.

[0038] The front frame assembly, serving as the power input side of the entire equipment, is centered on drive transmission and mainly consists of the front frame steel structure 3, the first circulating large sprocket set 5, the drive and transmission system 6, the first circulating large chain 7, the first triangular support plate 8, and the first bottom arc tensioning structure 9. The front frame steel structure 3 provides the mounting and bearing base for all components; the first circulating large sprocket set 5 includes a first driving large sprocket and a first driven large sprocket arranged vertically to drive the first circulating large chain 7; the drive and transmission system 6 uses a three-in-one geared motor as the power source, and transmits the power to the first driving large sprocket after reducing and increasing torque through the sprocket transmission pair and coaxial gear, thereby driving the first circulating large chain 7 to rotate in a ring; the first triangular support plate 8 is fixed to the pin shaft of the first circulating large chain 7 at the designed spacing, serving as the direct lifting and bearing component of the front end of the vehicle pallet 22; the first bottom arc tensioning structure 9 is set at the bottom of the inner side of the first circulating large chain 7 to adjust the tension of the first circulating large chain 7.

[0039] The rear frame assembly serves as the attitude constraint side of the entire equipment, with guiding and stabilizing functions as its core. It is arranged symmetrically with the front frame assembly and mainly consists of the rear frame steel structure 4, the second circulating large sprocket group 11, the second circulating large chain 12, the second triangular support plate 13, the guide rail support structure 14, the guide rail 15, and the second bottom arc tensioning structure 16. The second circulating sprocket assembly 11 also includes a second driving sprocket and a second driven sprocket arranged vertically to cooperate with the operation of the second circulating chain 12 on the same side. The upper second driving sprocket is rigidly linked to the first driving sprocket through the synchronous transmission shaft 24, without an independent drive unit. The second circulating chain 12 and the second triangular support plate 13 are consistent with the specifications and positions of the front frame side, and together with the front end components, they realize the synchronous lifting of the vehicle pallet 22. The guide rail 15 adopts the form of a cross rail that avoids the running trajectory of the central axis of the triangular support plate. A total of 4 independent circular rails are set. They are fixed to the rear frame steel structure 4 through the guide rail support structure 14 and cooperate with the guide wheel assembly of the vehicle pallet 22 to constrain the vehicle pallet 22 to maintain a horizontal posture throughout the entire stroke.

[0040] First, pre-assembly of the front and rear frame assemblies is carried out in the ground construction area. The front frame steel structure 3 is assembled by bolting the steel components into a single load-bearing frame. Then, the drive and transmission system 6, the first circulating large sprocket group 5, the first circulating large chain 7, and the first triangular support plate 8 are sequentially assembled onto the frame. The drive and transmission system 6 uses a three-in-one geared motor as its power source, driving the coaxial rotary support gear through sprocket transmission. The gear and the first active large sprocket are an integrated structure, enabling stable high-torque transmission. The first triangular support plate 8 is fixed to the pin shaft of the first circulating large chain 7 at designed intervals, serving as the installation support component for the front load-bearing shaft of the vehicle pallet 22. After pre-assembly, the first bottom arc tensioning structure 9 is adjusted to pre-tension the first circulating large chain 7, eliminating chain assembly gaps and initial sag, preventing chain slippage or derailment during subsequent hoisting and transportation, thus forming a complete front frame assembly.

[0041] Simultaneously assemble the rear frame assembly: After the steel structure 4 of the completed frame is spliced, assemble the second circulating large sprocket group 11, the second circulating large chain 12, and the second triangular support plate 13 in sequence, while simultaneously installing the guide rail support structure 14 and the guide rail 15. The guide rail 15 adopts a cross-rail form with a total of 4 independent tracks to avoid the running trajectory of the central axis of the second triangular support plate 13. It is adapted to the guide wheel group on the stabilizing guide frame 17 of the vehicle pallet 22 and is the core constraint component to ensure that the vehicle pallet 22 maintains a horizontal attitude throughout the process. As the attitude constraint component for the operation of the vehicle pallet 22, the straightness of the installation and the relative position accuracy of the guide rail 15 directly affect the horizontal maintenance effect and running stability of the vehicle pallet 22. The assembly on the ground can be highly accurate with the help of tools such as levels and theodolites, and the working conditions are far better than those in the confined space underground. According to design requirements, an auxiliary guide rail can also be added to the front frame to reduce the number of guide wheels of the vehicle pallet 22 and further simplify the assembly process. After the rear frame is pre-assembled, the second bottom arc tensioning structure 16 is used to pre-tension the second loop chain 12 to form the rear frame assembly.

[0042] While the frame assembly is pre-assembled, the vehicle pallet 22 is assembled simultaneously: the pallet structure plate 10 of the vehicle pallet 22 is welded and formed as a whole in the factory. On site, only the stabilizing guide frame 17 and the guide wheel assembly need to be installed to the end of the pallet structure plate 10 to form a complete vehicle pallet 22 unit. According to the equipment parking capacity design, the number of vehicle pallet 22 units is usually an even number of no less than 6.

[0043] By adopting a ground-based pre-assembly method, the open working space and complete tooling conditions can be fully utilized to improve the assembly accuracy of core components. At the same time, a large amount of assembly work is transferred to the ground, significantly reducing the downhole construction time and lowering the difficulty of safety management. If the on-site construction site is small, the assembly and hoisting of a single frame assembly can be completed sequentially before proceeding to the assembly of the next frame assembly, flexibly adapting to different site conditions.

[0044] After the two sets of frame assemblies pass the pre-assembly inspection, the front frame assembly and the rear frame assembly are vertically hoisted into the underground shaft 2 using hoisting equipment. During the hoisting process, the traction rope at the shaft opening is used to assist in alignment and control the horizontal attitude of the frames to avoid collisions between the frames and the inner wall of the shaft 2. When the bottom of the frame falls close to the embedded parts at the bottom of the shaft 2, the construction personnel go down into the shaft to assist in alignment and align the base plates at the bottom of the two sets of frames with the embedded anchor bolts 18, completing the initial fixation of the bottom of the frames. During the initial fixation stage, the anchor bolts 18 are not tightened temporarily, leaving a certain amount of fine adjustment margin. At the same time, temporary fixing fixtures are added to assist in limiting the two sets of frames to prevent the frames from tilting and becoming unstable during the adjustment process, providing adjustment space for subsequent shaft opening adjustments.

[0045] Using the pre-embedded parts at the bottom as a vertical positioning reference ensures that the installation position at the bottom of the frame corresponds precisely to the civil foundation, providing a fundamental guarantee for the long-term stress stability of the overall structure.

[0046] After the initial fixing of the bottom of the frame is completed, a positioning adjustment device is installed on the top of the wellbore 2. Each frame assembly is equipped with two sets of positioning adjustment devices. The positioning adjustment device includes a mounting base 19, a positioning base 20, and a positioning adjustment screw 21. The mounting base 19 is fixed to the pre-embedded steel plate at the edge of the wellhead. The positioning base 20 is connected to the mounting hole of the corresponding top crossbeam of the frame. In addition to adjusting the horizontal position, the height position can also be adjusted through the threaded structure. The positioning adjustment screw 21 is arranged in two orthogonal directions, front-back and left-right, respectively, to adjust the horizontal displacement and tilt of the frame.

[0047] During the adjustment process, the construction personnel screwed the corresponding positioning adjustment screws 21 at the wellhead, applying a horizontal force to the top of the frame through the screws. Using the initial fixed point at the bottom as the fulcrum, they fine-tuned the tilt angle and horizontal position of the frame, adjusting the verticality of the front frame assembly and the rear frame assembly, as well as their relative distance, to within the preset installation accuracy range. After the adjustment was completed, the bottom anchor bolts 18 were tightened to complete the initial positioning of the frame.

[0048] This wellhead calibration operation mode allows all core precision adjustment procedures to be completed at the surface wellhead, eliminating the need for personnel to enter the deep well for high-altitude alignment operations. This reduces construction safety risks and facilitates precision testing and repeated corrections during the calibration process. It can stably ensure the parallelism and coaxiality of the front and rear frames, providing the prerequisites for the subsequent synchronous operation of the chain and the precise alignment of the guide rail 15.

[0049] After the frame is positioned, front and rear connecting rods 23 are installed between the front frame assembly and the rear frame assembly. The rods are installed sequentially from the bottom of the shaft 2 upwards, first assembling the transverse rods 25, and then assembling the diagonal rods 26. The two sets of frames are connected into an integral space truss structure through the rods, which improves the overall torsional stiffness and bending performance of the structure to withstand the dynamic load generated by the chain circulation during equipment operation.

[0050] While the tie rods are being installed, the wiring of the electrical system and the installation of the control box can be carried out simultaneously, thus compressing the overall construction cycle through parallel processing. After all the front and rear connecting tie rods 23 are installed and locked, the first bottom arc tensioning structure 9 and the second bottom arc tensioning structure 16 are adjusted again to perform secondary tensioning on the first circulating chain 7 and the second circulating chain 12, respectively. Since there is a difference in the overall stress state between the single-frame pre-installed state and the double-frame connection state, the secondary tensioning can eliminate the chain tension changes caused by the frame connection, ensuring that the tension of the two sets of circulating chains is consistent and avoiding the problem of asynchronous operation caused by tension differences.

[0051] Before installing the synchronous drive shaft 24, first connect the temporary power supply to the drive and transmission system 6, and drive the first circulating chain 7 to run at low speed by the drive motor. Adjust the relative phase of the two sets of circulating chains until the first triangular support plate 8 and the corresponding second triangular support plate 13 are completely coaxially aligned in the front and rear direction. Then stop the chain operation and maintain the position.

[0052] After phase alignment, the synchronous drive shaft 24 is inserted between the axles of the first and second drive sprockets to complete the fixed connection. Before this, the temporary fixing fixtures of the front and rear frames need to be removed to release the structural freedom and avoid the fixture constraints affecting the synchronous operation debugging accuracy. After the connection is completed, the drive system is started for low-speed forward and reverse rotation debugging to check the synchronous operation status of the first circulating chain 7 and the second circulating chain 12. After confirming that there is no jamming, no phase difference, and no abnormal noise, the synchronous operation debugging is completed.

[0053] Aligning the phases before installing the drive shaft 24 can avoid additional internal stress during the assembly process of the drive shaft 24, prevent the drive shaft 24 from being subjected to torsional fatigue and uneven chain wear during operation, and ensure the operating accuracy and service life of the transmission system from the installation stage.

[0054] The circulating sprocket assembly and the circulating chain are the core transmission pairs that mesh with each other. The driving sprocket and driven sprocket, arranged vertically and vertically respectively, together open and limit the vertical circular running trajectory of the circulating chain. The driving sprocket transmits power through tooth meshing, driving the circulating chain to operate in a closed loop. The two sets of sprockets are rigidly linked by the synchronous drive shaft 24, which can ensure that the chains on both sides are moving at the same speed and in sync. With the bottom tensioning structure to adjust the center distance of the sprockets, the chain tension can be precisely controlled to ensure reliable meshing and smooth operation.

[0055] After successful synchronous debugging, the installation of the vehicle pallet 22 is carried out. The installation process makes full use of the equipment's own cyclic operation function. The electrical control system controls the first circulating chain 7 and the second circulating chain 12 to operate intermittently in the forward and reverse directions, so that the first triangular support plate 8 and the second triangular support plate 13 at the installation position are always stationed at the vehicle storage and retrieval position at the top of the shaft 2. The construction personnel hoist and align the vehicle pallet 22 at the wellhead position, and fix the lifting shafts at the front and rear ends of the vehicle pallet 22 to the corresponding mounting holes at the top of the first triangular support plate 8 and the second triangular support plate 13, respectively. At the same time, the guide wheels on the stabilizing guide frame 17 are embedded into the track grooves of the corresponding guide rail 15.

[0056] The installation process adopts an alternating left-right assembly sequence. After the installation of the vehicle pallet 22 on each side is completed, the chain is rotated to switch to the corresponding workstation on the other side for installation, so that the load on both sides of the frame is always balanced and the frame deformation caused by continuous installation on one side is avoided.

[0057] After all the vehicle pallets 22 are assembled, the first bottom arc tensioning structure 9 and the second bottom arc tensioning structure 16 are adjusted again to perform a third tensioning on the two sets of circulating chains. Under full load, the chain will undergo a certain elastic elongation under tension, resulting in increased sag. The third tensioning is to make a final correction to the chain tension under full load conditions, ensuring that the chain and sprocket always maintain reliable engagement, reducing vibration and the risk of tooth skipping during operation, and improving the stability of equipment operation.

[0058] Before performing the whole machine cycle operation debugging, the layout and wiring debugging of all position sensors must be completed first, including the chain upper and lower limit sensors, the vehicle pallet 22 position sensor, the opening and closing limit sensor, etc. The signals of all kinds of sensors are connected to the equipment control system to provide a foundation for position detection and safety protection for subsequent debugging and operation.

[0059] After the sensors are installed, the sides of the front and rear frame assemblies are anchored to the embedded parts on the sidewall of shaft 2. Lateral support further enhances the overall structure's resistance to lateral displacement, reducing the lateral sway amplitude during equipment operation. Once the overall structural connection is confirmed to be stable and its rigidity meets requirements, the positioning and adjustment device on the top of shaft 2 is removed. This device is an installation tool; after removal, it can be recycled and reused in other projects, which helps control construction costs.

[0060] After the positioning and adjustment device is removed, a telescopic protective plate assembly is installed at the opening at the top of the shaft 2. The lateral fixing supports of the telescopic protective plate 27 are connected to the embedded parts on the side wall of the shaft 2 to ensure the support rigidity during the opening and closing of the protective plate. The telescopic protective plate 27 assembly includes two sets of openable protective plate bodies on the left and right and a drive unit. When the vehicle is being stored or retrieved, the protective plate closes to cover the open areas on both sides of the vehicle pallet 22, providing safety support for personnel passage and expanding the effective operating space for storing and retrieving vehicles. When the equipment is in cyclic operation, the protective plate opens to both sides to avoid the running trajectory of the vehicle pallet 22 and prevent interference and collision.

[0061] After installation, the drive unit of the telescopic protective plate 27 is connected to the equipment control system. Interlocking and debugging are carried out in conjunction with the opening and closing position sensor to ensure that the equipment can start cyclic operation only after the protective plate is fully opened, and the protective plate cannot perform the closing action during the operation of the equipment. The risk of operational interference is eliminated through electrical interlocking, thereby improving the safety performance of the equipment.

[0062] After the telescopic protective plate 27 passes the linkage test, the vehicle entrance hall 28 structure is installed on the top of the shaft 2, and the assembly and wiring of the hall shell, automatic door, operation panel and other components are completed. Then, it is connected to the vehicle control system to perform a full-process vehicle storage and retrieval test. The test is carried out under multiple working conditions of no load, half load and full load in sequence to simulate the real vehicle storage and retrieval conditions. The functions of vehicle recognition, protective plate opening and closing, vehicle pallet 22 cyclic operation, positioning and locking, safety protection and other functions are verified in sequence, and the smoothness of operation, positioning accuracy and safety interlock reliability are tested.

[0063] Once all test items pass, the installation and positioning of the entire underground lifting-type vertical circulation three-dimensional parking system 1 is completed.

[0064] The installation method described in this embodiment, through process optimization and tooling coordination, significantly reduces the amount of underground high-altitude work while ensuring installation accuracy and structural reliability, thereby improving construction efficiency and safety. The overall process follows the principle of bottom-up and equipment-first-then-person arrangement, with no cross-interference between processes on different work surfaces, effectively ensuring personnel safety during construction. It is applicable to the installation and construction of various underground silo-type vertical circulation parking systems.
