Description

Technical Field

[0001] The present invention relates to the technical field of bridge auxiliary installation, and in particular to an assembled underground station trough bridge installation system and a method of using the same. Background Art

[0002] During the construction and operation of underground stations, laying numerous computer, communication, and control cables is crucial for ensuring their smooth operation. Trough cable trays, with their fully enclosed design, effectively shield against external interference and prevent corrosion, are ideal for supporting and protecting these critical cables. However, the complex layout of cables and limited space within underground stations pose challenges to the installation of trough cable trays, particularly in terms of flexibility and adaptability.

[0003] Existing trough-type cable tray installation equipment is typically fixed in design and can only accommodate specific cable tray lengths, making it difficult to meet the diverse cable installation requirements of underground stations. These devices often only provide support at the ends of the cable tray, causing the middle of long cable trays to sag and deform, compromising cable safety and system stability. Furthermore, traditional manual installation methods are not only inefficient but also pose safety risks. A new installation system is urgently needed to improve installation efficiency and safety.

[0030] Before starting installation, conduct a comprehensive inspection of all bridge installation system components to ensure the integrity and functionality of key components such as the bridge stabilization mechanism, lifting mechanism, auxiliary lifting mechanism, auxiliary ladder, etc., paying special attention to the functional status of equipment such as the moving wheels, lifting hydraulic cylinder group, retractable motor, and guide winch;

[0031] A2. Component transportation;

[0032] The two bridge stabilization mechanisms are fixed together using a stable locking mechanism to ensure the stability of the system during transportation, making it easier to safely transport the equipment to the construction site.

[0033] B: On-site layout;

[0034] B1. Site assessment and cleaning;

[0035] Determine the specific installation location and path of the bridge according to the design drawings, and thoroughly clean the installation area to remove any obstacles to facilitate the movement and operation of the entire system;

[0036] B2, system in place;

[0037] Use the moving wheels on the bridge stabilization mechanism to move the system to the intended initial installation location;

[0038] C: System movement and positioning;

[0039] C1: Locking mechanism unlocked;

[0040] After reaching the predetermined position, release the securing locking mechanism between the two bridge securing mechanisms to prepare for installation;

[0041] C2: preliminary positioning;

[0042] Perform a preliminary and stable positioning on one of the bridge stabilization mechanisms;

[0043] C3: final positioning;

[0044] Perform the final stable positioning of another bridge stabilizing mechanism;

[0045] D: Bridge support and positioning;

[0046] D1: Adjustment of lifting cloth and auxiliary rope;

[0048] D2: auxiliary support arrangement;

[0049] Arrange the auxiliary lifting mechanism as needed, adjust the position using the moving wheels and stabilizing foot assembly, use the guide assembly to ensure precise alignment, and then unfold the auxiliary lifting frame to provide necessary support;

[0050] D3. Preparation for bridge installation;

[0051] Place the trough bridge on the lifting platform and assemble it into the required length using screws; then, use the bridge lifting mechanism to gradually lift the bridge to the installation height, while using the auxiliary lifting mechanism to keep the middle part from sagging;

[0052] E: Bridge installation stage;

[0053] E1. Head end installation;

[0054] Construction workers can use auxiliary ladders to approach the bridge, then use the bridge hanger to install the bridge on the ceiling, and finally complete the fixing and adjustment of the first bridge;

[0055] E2: middle section installation;

[0056] Adjust the stabilizing lifting assembly and the moving ball unit to move the bridge stabilizing mechanism along the guide assembly to the next installation point; repeat the lifting and positioning steps to continue installing the middle section of the bridge;

[0062] This invention utilizes a modular design, each of which features adjustable modules. For example, the movable mechanisms on the stabilizing and auxiliary mechanisms allow the support position to be adjusted according to site conditions. Through the movable bridge stabilizing and auxiliary lifting mechanisms, the system can adapt to the complex and ever-changing environments of underground stations, allowing for flexible adjustment of installation position and posture even in conditions of limited space and dense pipelines. The bridge lifting mechanism is equipped with a retractable lifting cloth and auxiliary hinge ropes, allowing it to accommodate bridges of varying lengths and layouts. This flexibility enables the system to adapt to the complex and ever-changing environments of underground stations.

[0063] This invention utilizes a lifting cloth, auxiliary hinge ropes, and an auxiliary lifting mechanism to form a fully supported and lifted bridge. The lifting cloth, like a bridge spanning both ends, provides primary support. The auxiliary hinge ropes located directly below provide additional lifting force. The auxiliary lifting mechanism provides partial support beneath the bridge, ensuring the long bridge remains flat during installation and preventing mid-section sagging and deformation, significantly improving safety and reliability.

[0064] The automated retraction and extension assembly and auxiliary rope assembly in this invention are controlled by a motor, significantly improving installation efficiency, reducing manpower requirements, and shortening the construction period. The secure locking mechanism during transportation ensures safe transportation of the equipment, reduces potential damage risks, and lowers overall project costs.

[0065] The guide assembly and auxiliary positioning system in this invention ensure accurate bridge installation, avoiding errors in traditional installation, reducing rework, and improving project quality. The support stabilization assembly and auxiliary lifting mechanism ensure the stability of the bridge during installation, prevent bridge deformation, protect internal cables, and extend service life.

[0066] The auxiliary ladder in this invention takes into account the safety and convenience of construction workers, reducing the risks of working at height and improving operational safety. Safety features such as a stable locking mechanism and docking locking rod not only ensure system stability during transportation, but also ensure structural safety during on-site operations.

[0067] The detachable and reconfigurable design of the present invention makes the system easy to maintain and adjust after installation, and the rapid arrangement and removal of the auxiliary lifting mechanism reduces interference with daily operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0115] A method for using a trough-type bridge installation system for an assembled underground station comprises the following steps:

[0116] A: Preliminary preparation and transportation;

[0117] A1. Component inspection;

[0118] Before starting installation, conduct a comprehensive inspection of all bridge installation system components to ensure the integrity and functionality of key components such as the bridge stabilization mechanism 100, lifting mechanism, auxiliary lifting mechanism 400, and auxiliary ladder. Pay special attention to the functional status of equipment such as the moving wheels, lifting hydraulic cylinder group 122, retractable motor, and guide winch 152;

[0119] A2. Component transportation;

[0120] The two bridge stabilizing mechanisms 100 are fixed together using a stabilizing locking mechanism 500 to ensure the stability of the system during transportation, facilitating safe transportation of the equipment to the construction site.

[0121] B: On-site layout;

[0122] B1. Site assessment and cleaning;

[0123] Determine the specific installation location and path of the bridge according to the design drawings, and thoroughly clean the installation area to remove any obstacles to facilitate the movement and operation of the entire system;

[0124] B2, system in place;

[0125] Use the moving wheels on the bridge stabilizing mechanism 100 to move the system to the intended initial installation position, while the moving wheels on the stabilizing base 110 should ensure that the mechanism can move smoothly;

[0126] C: System movement and positioning;

[0127] C1: Locking mechanism unlocked;

[0128] After reaching the predetermined position, the securing locking mechanism 500 between the two bridge securing mechanisms 100 is released to prepare for installation;

[0129] C2: preliminary positioning;

[0130] Perform a preliminary stabilization and positioning of one of the bridge stabilization mechanisms 100; activate the stabilization lifting assembly 120 and lift the bridge stabilization mechanism 100 to a suitable height by lifting the hydraulic cylinder assembly 122; then activate the supporting stabilization assembly 130 to make the stabilization unit 132 contact the ceiling and provide preliminary fixation to ensure the stability of the bridge stabilization mechanism 100 system;

[0131] C3: final positioning;

[0132] The other bridge stabilizing mechanism 100 is finally stabilized and positioned; the retracting and extending assembly 310 and the auxiliary rope assembly 360 in the bridge lifting mechanism 300 are activated, the lifting cloth 200 is retracted and extended by the retracting and extending motor, and the auxiliary hinge rope 361 is retracted and extended by the auxiliary winch, the lifting cloth 200 and the auxiliary hinge rope 361 are deployed to the required length, so that the other bridge stabilizing mechanism 100 moves compared with the above bridge stabilizing mechanism 100. When the other bridge stabilizing mechanism 100 reaches the expected position, the above step C2 is repeated at the same time, so that the other bridge stabilizing mechanism 100 is stabilized and positioned;

[0133] D: Bridge support and positioning;

[0134] D1: Adjustment of lifting cloth 200 and auxiliary rope;

[0135] Initially tighten the lifting cloth 200 and the auxiliary rope to form a stable lifting platform; start the retractable assembly 310 and the auxiliary rope assembly 360 in the bridge lifting mechanism 300, control the retraction and extension of the lifting cloth 200 through the retractable motor, and control the retraction and extension of the auxiliary hinge rope 361 through the auxiliary winch, and perform preliminary tightening on the lifting cloth 200 and the auxiliary hinge rope 361 in the previous step, providing a preliminary lifting platform for the subsequent placement of the bridge;

[0136] D2: auxiliary support arrangement;

[0137] Arrange the auxiliary lifting mechanism 400 as needed, adjust the position using the moving wheels and stabilizing foot assembly 420, use the guide assembly 150 to ensure precise alignment, and then deploy the auxiliary lifting frame 440 to provide the necessary support;

[0138] According to the length of the bridge, the installation position of the auxiliary lifting mechanism 400 is adjusted using the moving wheels and the stabilizing foot assembly 420. At the same time, the guide winch 152 and the guide hinge rope in the guide assembly 150 are used to fine-tune the position of the bridge stabilizing mechanism 100 to ensure that the bridge is accurately installed in the designed position.

[0139] Each auxiliary lifting mechanism 400 is then deployed, and the stabilizing foot assembly 420 on the auxiliary base 410 is used to provide additional support, while the expansion assembly 430 is used to stably fix the auxiliary lifting mechanism 400;

[0140] Subsequently, the lifting plate is fixed under the lifting platform by the auxiliary lifting frame 440 and the auxiliary frame 450 to prevent the middle part of the lifting platform from sagging and ensure the stability of the lifting platform;

[0141] D3. Preparation for bridge installation;

[0142] Place the trough bridge on the lifting platform and assemble it into the required length using screws; then, use the bridge lifting mechanism 300 to gradually lift the bridge to the installation height, while using the auxiliary lifting mechanism 400 to keep the middle part from sagging;

[0143] Specifically, the bridge support mechanism 300 is activated, the retractable assembly 310 and the auxiliary rope assembly 360 in the bridge support mechanism 300 are deployed, the retractable and retractable motor controls the retraction and extension of the support cloth 200, and the auxiliary winch controls the retraction and extension of the auxiliary hinge rope 361, thereby preliminarily loosening the support cloth 200 and the auxiliary hinge rope 361 in the previous step;

[0144] At the same time, the lifting unit 340 drives the lifting base 330 to move up and down, and then the tension wheel assembly 350 applies a lifting force to gradually lift it to a predetermined height;

[0145] Subsequently, the lifting assembly drives the tension frame 365 to move up and down, and then the tensioning and telescopic assembly 366 applies a lifting force, gradually lifting it to a predetermined height, so that the auxiliary hinge rope 361 is located directly below the lifting cloth 200, providing a certain lifting force for the lifting cloth 200;

[0146] Finally, each auxiliary lifting mechanism 400 is further deployed, and the lifting plate is fixed under the lifting platform through the auxiliary lifting frame 440 and the auxiliary frame 450 to prevent the middle part of the lifting platform from sagging, thereby providing further stable support for the lifting platform;

[0147] E: Bridge installation stage;

[0148] E1. Head end installation;

[0149] Construction workers can use auxiliary ladders to approach the bridge, then use the bridge hanger to install the bridge on the ceiling, and finally complete the fixing and adjustment of the first bridge;

[0150] E2: middle section installation;

[0151] Adjust the stabilizing lifting assembly 120 and the moving ball unit 133 to move the bridge stabilizing mechanism 100 along the guide assembly 150 to the next installation point; repeat the lifting and positioning steps to continue installing the middle section bridge;

[0152] When the bridge stabilizing mechanism 100 encounters the auxiliary lifting mechanism 400, the pulley assembly 460 located in the auxiliary lifting mechanism 400 causes the auxiliary lifting mechanism 400 to separate from the guide assembly 150, thereby completing the removal of the stable auxiliary lifting mechanism 400 located between the two bridge stabilizing mechanisms 100.

[0153] Specifically, the construction worker uses the stabilizing lifting assembly 120 to make the moving wheels contact the ground, then uses the stabilizing touch plate in the stabilizing unit 132 to detach from the ceiling, and then uses the moving ball unit 133 to contact the ceiling. Under the guidance of the guide assembly 150, the bridge stabilizing mechanism 100 at one end moves relative to the bridge stabilizing mechanism 100 at the other end, and then the bridge stabilizing mechanism 100 moves to the next section of the bridge installation;

[0154] Subsequently, the retractable assembly 310 and the auxiliary rope assembly 360 in the bridge support mechanism 300 are activated, and the retractable and retractable lifting cloth 200 is controlled by the retractable motor, and the retractable and retractable auxiliary rope 361 is controlled by the auxiliary winch, thereby preliminarily tightening the lifting cloth 200 and the auxiliary rope 361 in the previous step;

[0155] Continue to repeat the above positioning steps to complete the initial fixation of the bridge stabilizing mechanism 100;

[0156] Continue to repeat the above lifting and positioning steps to complete the installation of the middle section bridge;

[0157] E3: Overall installation completed;

[0158] By gradually advancing, the installation of the entire bridge is completed, ensuring the stability and precision of each link;

[0159] F; Disassembly and finishing stage;

[0160] After installation is complete, reverse the above steps to lower the lifting mechanism, release the tension of the auxiliary rope, remove the auxiliary lifting mechanism 400 and relock the bridge frame stabilizing mechanism 100, and finally use the wheels to move the system out of the installation area for next use;

[0161] Specifically, after the bridge is installed, the height of the tensioning frame 365 is first lowered to release the tension of the auxiliary hinge rope 361, and then the height of the lifting base 330 is lowered to release the tension of the lifting cloth 200;

[0162] Subsequently, the auxiliary lifting mechanism 400 removed in the above step is collected and the lifting mechanism is retracted. The pulley assembly 460 is then used to secure the auxiliary lifting mechanism 400 to the guide assembly 150. The locking hinge rope is then passed through the lock and slot to engage with the locking hook.

[0163] Subsequently, the two bridge stabilizing mechanisms 100 and the auxiliary lifting mechanism 400 located between the two bridge stabilizing mechanisms 100 are locked by using the docking locking rod, so that the entire installation system returns to its initial compact state;

[0164] The entire system can be transported from the site on wheels for its next use.

[0165] Through the above steps, the prefabricated underground station trough bridge installation system can efficiently and safely complete the installation of the trough bridge, solving the problems of insufficient flexibility, low efficiency and safety hazards in traditional installation methods.

[0166] Technical features not described in the present invention can be achieved through or by adopting existing technologies and will not be described in detail here. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
