Description

TECHNICAL FIELD

[0001] The present application relates to the field of engineering surveying, and in particular to a real-time monitoring system and method applied to a jacking device of a large-span truss. BACKGROUND

[0002] With the development of construction technology, steel structures are increasingly favored by the market and widely used in various fields of construction due to their characteristics of light weight, easy installation and disassembly, high precision, etc. At the same time, complex steel structure systems can be decomposed according to components to realize design, processing, storage and transportation, installation and other production line operations, increase the proportion of factory production, reduce the time cost of on-site wet work and maintenance, and reduce the original deviation caused by manual operation.

[0003] At present, the hoisting of large steel structures, especially the hoisting of large-span steel truss structures, requires high standards. When the construction crane is difficult to hoist into place, the construction crane has a narrow operating range, and the assembly occupies a limited area, a temporary support combined with a jacking device is used. The jacking device is used to jacking and moving the steel structure platform on the top of the temporary support, so that the steel structure platform is moved to the designated position.

[0004] According to the related technology in the above, the inventor believes that when the jacking device jacks the steel structure platform, the weight distribution of the steel structure platform on the top of the temporary support changes, which easily leads to uneven stress of part of the temporary support and vertical displacement deviation, resulting in the risk of tilting of the steel structure platform on the top of the temporary support. SUMMARY

[0005] In order to reduce the risk of tilting of the steel structure platform on the top of the temporary support, the present application provides a real-time monitoring system and method applied to a jacking device of a large-span truss.

[0006] In a first aspect, the real-time monitoring system applied to a jacking device of a large-span truss provided by the present application adopts the following technical solution:

[0007] A real-time monitoring system applied to a jacking device of a large-span truss, comprising

[0008] A horizontal displacement monitoring unit is arranged on both sides of the temporary support for monitoring the horizontal state of the jacking device.

[0009] A data analysis unit is connected to the horizontal displacement monitoring unit for comparing the monitoring data of the horizontal displacement monitoring unit with a preset horizontal threshold.

[0010] A hydraulic device is connected to the temporary support for adjusting the height position of the jacking device on the top of the temporary support.

[0011] By adopting the technical scheme, after the steel structure platform is placed on the top of the temporary support, the pushing device is started to push the steel structure platform in a specified direction, the horizontal displacement monitoring part monitors the horizontal state of the pushing device and obtains monitoring data of the horizontal state of the pushing device, and the data analysis part compares the monitoring data obtained by the horizontal displacement monitoring part with a preset horizontal threshold. When the monitoring data obtained by the horizontal displacement monitoring part exceeds the preset horizontal threshold, the hydraulic device is started to adjust the height position of the pushing device on the top of the temporary support to adjust the horizontal state of the pushing device, so as to adjust the horizontal state of the steel structure pushed by the pushing device. Through the monitoring of the pushing device by the horizontal displacement monitoring part, not only the horizontal state of the pushing device when being installed on the top of the temporary support is detected, but also the hydraulic device is used to dynamically adjust the horizontal state of the steel structure platform on the top of the temporary support during the pushing of the steel structure platform by the pushing device, so as to reduce the risk of tilting of the steel structure platform on the top of the temporary support.

[0012] Optionally, the counterweight device is further connected to the steel structure platform and used to adjust the weight distribution of the steel structure platform on the top of the temporary support.

[0013] By adopting the technical scheme, the introduction of the counterweight device enables the weight distribution of the steel structure platform on the top of the temporary support to be adjusted, and the hydraulic device is used to compensate for the horizontal deviation of the steel structure platform on the top of the temporary support when the steel structure platform moves on the top of the temporary support, thereby improving the compensation accuracy of the horizontal deviation of the steel structure platform.

[0014] Optionally, the counterweight device comprises a longitudinal sliding track beam installed on the steel structure platform and a counterweight block slidingly connected to the longitudinal sliding track beam, the longitudinal sliding track beam is arranged in extension along the moving direction of the steel structure platform on the top of the temporary support, and the sliding direction of the counterweight block is parallel to the axial direction of the longitudinal sliding track beam.

[0015] By adopting the technical scheme, the introduction of the longitudinal sliding track beam and the counterweight block enables the position of the counterweight block to be changed when the counterweight block slides, so that the weight distribution of the steel structure platform on the top of the temporary support can be adjusted in real time, thereby correcting the tilting state of the steel structure platform on the top of the temporary support and restoring the steel structure platform from the tilting state to the horizontal state during the movement of the steel structure platform.

[0016] Optionally, the counterweight block is a counterweight hydraulic crawler connected to the longitudinal sliding track beam in sliding mode.

[0017] By adopting the above technical scheme, the pressure of the counterweight hydraulic creeper is adjusted to realize the adjustment of the moving speed of the counterweight block on the longitudinal sliding rail beam, so that the moving efficiency and position of the counterweight block adapt to the jacking efficiency of the jacking device, the counterweight block adapts to the steel structure platform in the dynamic moving process, and the counterweight block can more accurately adjust the weight distribution effect of the steel structure platform on the top of the temporary support.

[0018] Optionally, the counterweight block is detachably connected with a weight increasing block.

[0019] By adopting the above technical scheme, the introduction of the weight increasing block enables the weight of the counterweight block to be increased or decreased, so that the counterweight block of different weights adapts to the steel structure platform of different weights, and the adaptability of the counterweight block to the steel structure platform of different weights is improved.

[0020] Optionally, the hydraulic device comprises a vertical sliding rail column, a jacking hydraulic creeper and a limiting piece; the vertical sliding rail column is connected to the temporary support, and one end of the vertical sliding rail column abuts against the bottom of the jacking device; the jacking hydraulic creeper is slidably connected to the vertical sliding rail column in the jacking direction of the jacking device, and the jacking hydraulic creeper is connected to the jacking device; and the limiting piece is used to limit the relative sliding of the jacking hydraulic creeper and the vertical sliding rail column when the jacking hydraulic creeper jacks up the jacking device.

[0021] By adopting the above technical scheme, the vertical sliding rail column not only provides a sliding basis for the jacking hydraulic creeper, but also supports the jacking device, can share the compressive stress of the temporary support, reduces the risk of stress concentration of the temporary support when the jacking device is running, and improves the service life and support stability of the temporary support. At the same time, the limiting piece is started when the jacking hydraulic creeper is started, the jacking hydraulic creeper jacks up the jacking device, the displacement deviation of the jacking device in the vertical direction is adjusted, and the introduction of the limiting piece improves the sliding problem of the jacking hydraulic creeper when jacking up the jacking device.

[0022] Optionally, each jacking device is correspondingly provided with a plurality of hydraulic devices.

[0023] By adopting the above technical scheme, the introduction of the plurality of hydraulic devices realizes the jacking effect of different positions of the jacking device, so as to further realize the effect of accurately adjusting the horizontal state of the jacking device.

[0024] In the second aspect, the application provides a real-time monitoring method of a jacking device applied to a large-span truss.

[0025] A real-time monitoring method of a jacking device applied to a large-span truss comprises the following steps:

[0026] Determine the level of the pushing device: after the pushing device is evenly distributed on the top of the temporary support, the pushing device is tested, and the level of the pushing device on the top of the temporary support is monitored in real time using the horizontal displacement monitoring part;

[0027] Install the steel structure platform: assemble the steel structure platform on the top of the temporary support for pushing by the pushing device;

[0028] Monitor the displacement posture of the steel structure platform: push the steel structure platform in the specified direction by the pushing device, and obtain the horizontal monitoring data by identifying the identification point of the pushing device through the horizontal displacement monitoring part;

[0029] Compensate for the horizontal displacement error of the steel structure platform: send the horizontal monitoring data to the data analysis part through the horizontal displacement monitoring part, and when the data analysis part detects that the horizontal monitoring data is lower than the preset horizontal threshold, start the hydraulic equipment connected to the temporary support, adjust the height of the pushing device on the top of the temporary support, and compensate for the displacement deviation of the pushing device in the vertical direction.

[0030] By adopting the above technical solutions, the combination of the horizontal displacement monitoring part and the data analysis part can monitor the level of the pushing device when it is installed on the top of the temporary support, and also monitor the level of the pushing device when it is pushing the steel structure platform to reflect the horizontal posture of the steel structure platform during displacement. After the data analysis part detects a change in the horizontal posture of the pushing device, the height of the pushing device on the temporary support is raised by the hydraulic equipment to compensate for the horizontal deviation of the pushing device, thereby compensating for the error of the horizontal displacement of the steel structure platform, and reducing the risk of tilting of the steel structure platform when it is pushed on the top of the temporary support.

[0031] Optionally, it also includes monitoring the stress change of the temporary support: using a stress measurement system to monitor the stress change of the temporary support in real time and obtaining a stress value, sending the stress value to the data analysis part through the stress measurement system and comparing it with a preset stress threshold, and if the stress value exceeds the preset stress threshold, reinforcing the corresponding position of the temporary support whose stress value exceeds the preset stress threshold.

[0032] By adopting the above technical solutions, since the stress of each part of the temporary support is always changing during the movement of the steel structure platform on the top of the temporary support, the stress change of each part of the temporary support is monitored in real time by using the stress measurement system and the data analysis part, and when the stress change of the temporary support exceeds the preset stress threshold, the corresponding position of the temporary support is reinforced in time, reducing the risk of bending of the temporary support due to stress concentration and improving the support stability of the temporary support, thereby reducing the risk of tilting of the steel structure platform during pushing by the pushing device.

[0033] Optionally, before reinforcing the temporary support, the hydraulic device and the pushing device are started to lift the steel structure platform off the top of the temporary support to adjust the horizontal state of the steel structure platform on the temporary support, and then the hydraulic device and the pushing device of the corresponding position of the temporary support whose stress value exceeds the preset stress threshold are closed.

[0034] By using the above technical scheme, the hydraulic device and the pushing device are used to lift the steel structure platform off the top of the temporary support to make the steel structure platform in a horizontal state, and then the hydraulic device and the pushing device of the corresponding position of the temporary support whose stress value exceeds the preset stress threshold are closed, so as to reduce the risk of stress of the corresponding position of the temporary support whose stress value exceeds the preset stress threshold, and to reinforce the corresponding position of the temporary support. Through the hydraulic device and the pushing device, the steel structure platform can be temporarily lifted, so as to reduce the risk of tilting of the steel structure platform during reinforcement of the temporary support. At the same time, the hydraulic device and the pushing device of the corresponding position of the temporary support whose stress value exceeds the preset stress threshold are closed, so as to reduce the stress of the corresponding position of the temporary support whose stress value exceeds the preset stress threshold, and to improve the safety during reinforcement of the temporary support.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. Through the monitoring of the pushing device by the horizontal displacement monitoring part, not only the horizontal state of the pushing device installed on the top of the temporary support is detected, but also the horizontal posture of the steel structure platform on the top of the temporary support is dynamically adjusted in cooperation with the hydraulic device during the pushing process of the pushing device, so as to reduce the risk of tilting of the steel structure platform on the top of the temporary support during pushing;

[0037] 2. Through the counterweight device, the weight distribution of the steel structure platform on the top of the temporary support can be adjusted, so as to realize the effect of real-time adjustment of the weight distribution of the steel structure platform on the top of the temporary support, thereby correcting the tilting state of the steel structure platform on the top of the temporary support, and compensating for the horizontal deviation of the steel structure platform on the top of the temporary support in cooperation with the hydraulic device, thereby improving the compensation accuracy of the horizontal deviation of the steel structure platform;

[0038] 3. Through the use of the stress measurement system and the data analysis part to monitor the stress change of each part of the temporary support in real time, when the stress change of the temporary support exceeds the preset stress threshold, the corresponding position of the temporary support is reinforced in time, so as to reduce the risk of bending of the temporary support caused by stress concentration, improve the support stability of the temporary support, and thereby reduce the risk of tilting of the steel structure platform during the pushing process of the pushing device.

[0059] S2: installing the steel structure platform 6: the steel structure platform 6 is assembled on the top of the temporary support 5, so as to be ready for pushing by the pushing device 4.

[0060] S3: monitoring the stress change of the temporary support 5: a, the stress change of the temporary support 5 is monitored in real time by using the stress measuring system, and a stress value is obtained; the stress value is sent to the data analysis part through the stress measuring system and compared with a preset stress threshold value; b, if the stress value exceeds the preset stress threshold value, the data analysis part sends a warning signal, and according to the warning signal, the hydraulic equipment 2 and the pushing device 4 are started to lift the steel structure platform 6 away from the top of the temporary support 5, so as to adjust the level state of the steel structure platform 6 on the top of the temporary support 5; c, the hydraulic equipment 2 and the pushing device 4 of the corresponding position of the temporary support 5 whose stress value exceeds the preset stress threshold value are closed, so that the corresponding position of the temporary support 5 whose stress value exceeds the preset stress threshold value is reduced in stress; d, the corresponding position of the temporary support 5 whose stress value exceeds the preset stress threshold value is reinforced, and the reinforcing method can be to increase reinforcement of the corresponding position of the temporary support 5, to increase the stress area of the temporary support 5, for example, to increase a steel column, or to support the corresponding position of the temporary support 5 by using a diagonal bracing.
