Anchor system including interim cord clip, is arranged on the upper anchorage of lifter upper and lower ends and lower anchorage, and upper anchorage is under Anchorage is wedge type anchorage, and steel strand cable one end is fixedly connected with cord clip, and steel strand cable sequentially passes through anchorage and lower anchorage, upper anchorage and Lower anchorage at least one be in locking state;
Detecting system, including being respectively arranged on the anchorage sensor on upper anchorage and lower anchorage, the row on arch bridge suspension centre Journey sensor, the pressure sensor on the oil cylinder of pumping station system and the distance detection sensor on arch bridge;
Alarm system, including Suo Li abnormal alarms device, displacement distance abnormal alarm device and pressure anomaly alarm;
Monitoring system, the computer with human-computer interaction interface including interconnection, the manual control for controlling dynamical system The wireless feedback module of molding block and automatic control module and wireless connection detecting system, computer are also reported extremely with Suo Li Alert device, displacement distance abnormal alarm device and the connection of pressure anomaly alarm.
Further, two anchorage sensors are arranged on the upper anchorage and lower anchorage of a steel strand cable, during installation, anchorage sensing Device and upper anchorage and between be equipped with plum blossom gasket between anchorage sensor and lower anchorage, the one side of anchorage sensor is equipped with single Hole anchor.
Further, upper anchorage and lower anchorage include grip and the tight fluid cylinder of anchor clamped with driving grip, the tight fluid cylinder of anchor It is connected with pumping station system pipeline, the solenoid valve being connected with monitoring system is equipped between the tight fluid cylinder of anchor and pumping station system.
The beneficial effects of the invention are as follows:
This vertical turning lifting synchronous control system is controlled by using stroke, Distance-sensing monitoring and computer, passes through data Feedback and control instruction transfer, can automatically realize synchronization action, load balancing, posture correction, force controlled, operation be latched, Process is shown and the function of corresponding failure alarm, to realize the synchronous vertical turning lifting with accurate control arch bridge.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
In order to which those skilled in the art is made to more fully understand technical scheme, below in conjunction with the accompanying drawings and most The present invention is described in further detail for good embodiment.
As shown in Figure 1, a kind of arch bridge vertical turning lifting of present invention promotion synchronous control system, including:
Dynamical system 2, including providing the lifter 8 of vertical turning lifting power, 8 and of connection lifter for two semicircle arch bridges The steel strand cable of bridge arch and the pumping station system that hydraulic coupling is provided to lifter 8, pumping station system include oil cylinder and are connected with oil cylinder piston Frequency conversion oil pump, can according to the load of the different angle of vertical turning lifting change hydraulic coupling, lifter 8 be even number, be symmetrical arranged In the both ends of pylon tower top;
Anchor system 9 including interim cord clip, is arranged on the upper anchorage of 8 upper and lower ends of lifter and lower anchorage, upper anchorage and Lower anchorage is wedge type anchorage, and steel strand cable one end is fixedly connected with cord clip, and steel strand cable sequentially passes through anchorage and lower anchorage, upper anchorage At least one is in locking state with lower anchorage, ensures the unidirectional promotion of steel strand cable or the reliability and stabilization of lowering action Property;
Detecting system, including being respectively arranged on the anchorage sensor 4 on upper anchorage and lower anchorage, the row on arch bridge suspension centre Journey sensor 6, the pressure sensor 7 on the oil cylinder of pumping station system and the range sensor on arch bridge 6;
Alarm system 10, including Suo Li abnormal alarms device, displacement distance abnormal alarm device and pressure anomaly alarm;
Monitoring system 1, the computer with human-computer interaction interface including interconnection control the manual of dynamical system 2 The wireless feedback module 3 of control module and automatic control module and wireless connection detecting system, computer are also abnormal with Suo Li Alarm, displacement distance abnormal alarm device and the connection of pressure anomaly alarm;
During work, monodirectional locking carries out steel strand cable by anchor system 9, computer long-distance control opens pumping station system, Pumping station system provides same hydraulic coupling for multiple lifters 8, passes through steel strand cable Synchronous lifting arch bridge;The anchorage sensing of detecting system Device 4 can detect the clamping dynamics of upper and lower anchorage in lifting process, when detecting that clamping force spends low, wireless feedback to calculating Machine, and pass through Suo Li abnormal alarm devices and warned in time;Due to vertical turning lifting process, angle change constantly occurs for arch bridge, With vertical displacement and lateral displacement, stroke sensor 6 can detect the height change of arch bridge vertical transfer, and range sensor 6 is detectable The lateral separation of a certain fixed point and a certain fixed point in turning hinge or ground changes on arch bridge during vertical turning lifting, to monitor arch Each dotted state of bridge vertical turning lifting, when a direction displacement is excessive, computer is judged as being promoted unstability according to preset value, it is mobile away from The normal alarm of divorced warns, and when the vertical turning lifting amount of each section of arch bridge is inconsistent, can be seen in real time by human-computer interaction interface It observes, and manually control module is controlled single lifter 8 to carry out single-point promotion adjustment manually;Pressure on oil cylinder passes Sensor 7 can detect the unobstructed situation of oil circuit in time.
Therefore, vertical turning lifting synchronous control system is controlled by using stroke, Distance-sensing monitoring and computer, passes through number It is transferred according to feedback and control instruction, can automatically realize that synchronization action, load balancing, posture correction, force controlled, operation are closed Lock, process are shown and the function of corresponding failure alarm, to realize the synchronous vertical turning lifting with accurate control arch bridge.
In this example, two anchorage sensors 4 are arranged on the upper anchorage and lower anchorage of a steel strand cable, during installation, anchorage sensing Device 4 and upper anchorage and between plum blossom gasket is equipped between anchorage sensor 4 and lower anchorage, the one side of anchorage sensor 4 is set There is single hole anchor so that steel strand cable, single hole anchor and plum blossom gasket coaxial line prevent that lateral deviation occurs during steel strand cable folding and unfolding, improves anchorage 4 accuracy of detection of sensor.
