Technical Field

[0001] This utility model relates to the field of lattice-type large-scale space frame jacking, specifically to a lattice-type large-scale space frame jacking system based on hydraulic synchronous control. Background Technology

[0002] In the field of bridge construction, there is the issue of lifting large lattice-type space frames. However, the traditional method for lifting large lattice-type space frames is to use hoisting equipment, which has the following shortcomings.

[0003] Poor synchronization: Traditional hoisting methods make it difficult to maintain synchronization when lifting multiple points, which can easily lead to space frame displacement or uneven stress, causing structural safety hazards.

[0004] Low dismantling efficiency: The hoisting method is complicated, and the dismantling is time-consuming and labor-intensive, which affects the construction progress;

[0005] Insufficient wind resistance: The space frame is easily affected by wind during the hoisting process, and there is a lack of effective dynamic stabilization measures;

[0006] High dependence on manual labor: Frequent manual checks and adjustments are required during operation, which is labor-intensive and makes it difficult to guarantee accuracy. Utility Model Content

[0007] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a lattice-type large-scale space frame jacking system based on hydraulic synchronous control, which is used to jack the space frame. The jacking process involves lifting one section with a hydraulic jack system and then adding another section of the standard section jacking system until the design height is reached.

[0008] This invention is implemented by constructing a lattice-type large-scale space frame jacking system based on hydraulic synchronous control. The jacking system is used to jack the space frame and includes a support, a jacking support, and hydraulic jacks. The hydraulic jacks are installed at the bottom of the support and mounted on the jacking support.

[0010] The support frame is used to lift the space frame and can be reused.

[0011] According to the present application, a lattice-type large-scale space frame jacking system based on hydraulic synchronous control is characterized in that: the hydraulic jacks are equipped with displacement sensors and pressure sensors, and the data is transmitted to the PLC system in real time to automatically adjust the jacking speed and height difference (height difference between adjacent points ≤12mm); displacement and pressure detection are synchronously transmitted to the computer system.

[0012] According to the present application, a lattice-type large-scale space frame jacking system based on hydraulic synchronous control is characterized in that: a jacking support is provided at the top of the support, which acts on the upper part of the jacking structure, so that the jacking system forms a reliable connection with the space frame.

[0013] This utility model has the following advantages: This application provides a lattice-type large-scale space frame jacking system based on hydraulic synchronous control, used for jacking the space frame. The jacking process involves lifting one section with a hydraulic jack system, then adding another standard section to the jacking system, until the designed height is reached. Quick assembly and disassembly: The bolt ball connection standard section design increases disassembly efficiency by 50% and shortens the construction period. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] This utility model provides a lattice-type large-scale space frame jacking system based on hydraulic synchronous control, such as... Figures 1-11 As shown, it can be implemented in the following manner;

[0023] It has a support frame 1, a lifting support 2, and a hydraulic jack 3;

[0024] The bracket 1 adopts a lattice structure with a planar dimension of 1.2m×1.2m, and the standard section height is 1m. It is connected by bolt balls 4 to achieve quick assembly and disassembly.

[0025] The support 1 is a support for lifting the space frame and can be reused;

[0026] Hydraulic jacks 3 are installed at the bottom of bracket 1. Hydraulic jacks 3 are located on lifting support 2 and can be fixed by lifting caps, connecting rods and pins to ensure uniform force distribution.

[0027] The hydraulic jack 3 is equipped with a displacement sensor and a pressure sensor. The data is transmitted to the PLC system in real time to automatically adjust the lifting speed and height difference (height difference between adjacent points ≤ 12mm).

[0028] A lifting support 5 is installed at the top of the support 1; it acts on the upper part of the lifting structure to make the lifting system reliably connected to the grid structure.

[0029] The bracket 1 adopts a lattice structure with a planar dimension of 1.2m×1.2m, and the standard section height is 1m. It is connected by bolt ball joints to achieve quick assembly and disassembly.

[0030] Hydraulic synchronous control system: The PLC control panel is linked with displacement sensors and oil pressure gauges to monitor and adjust the lifting height and pressure value of each hydraulic jack in real time.

[0031] Each pump station independently controls one jack, and controls the oil circuit opening and closing through a solenoid valve to achieve synchronous or individual operation of multiple jacks.

[0032] Modular lattice support such as Figure 1 As shown. A uniform preload is applied before jacking to ensure consistent initial conditions.

[0033] Synchronization control method

[0034] Dual feedback mechanism for displacement and pressure: Each jack is equipped with a displacement sensor and a pressure sensor, and the data is transmitted to the PLC system in real time to automatically adjust the lifting speed and height difference (height difference between adjacent points ≤ 12mm).

[0035] like Figure 4 As shown, the lifting process is described as follows:

[0036] 1. First, place the lifting equipment such as Figure 4 Everything is ready as shown;

[0037] 2. When the lifting begins and H > 1000, add a standard section below.

[0038] 3. The jack will fall, and the lifting support will rest on the lifting support;

[0039] 4. Move the jacks to the next stage of jacking and continue jacking in the next stage. Continue until the space frame is jacked to the design elevation.

[0040] Segmented lifting cycle:

[0041] Lift the jack to the upper limit of its stroke (1.25m) → pause → install the next standard section → lower the jack → transfer the load to the support → repeat the cycle to the design elevation.

[0042] This application has the following technical effects:

[0043] This application provides a hydraulically synchronized control-based lattice-type large-scale space frame jacking system for jacking the space frame. The jacking process involves lifting one section using a hydraulic jack system, then adding another standard section to the jacking system, until the designed height is reached. Rapid assembly and disassembly are achieved through a bolted ball joint standard section design, increasing disassembly efficiency by 50% and shortening the construction period.
