Flexibly support continuous beam.It can be such that moment of flexure in beam body reduces, and reduce building height, alleviate construction weight, save material.Tiltedly
Bridge is drawn mainly to be made of Sarasota, girder, suspension cable, wherein suspension cable is the important component of drag-line bridge, and suspension cable includes rope
Rope, rope rope are generally made of steel strand wires, and the both ends of rope rope pass through inhaul cable anchorage structure respectively and are connected with tower and pontic.Existing drawing
Rope anchor structure is as shown in Figure 1, include the bearing cylinder 4 for being fixedly connected on 1 one end of rope rope, the periphery of bearing cylinder 4 is provided with outer spiral shell
Line supports and is threaded with adjusting nut 3 on the external screw thread of cylinder, and one end contact of adjusting nut is fixedly connected with tower or pontic
Anchor plate 2 on.When in use, anchor plate is fixed together with tower or pontic, by screwing adjusting nut, carrys out side tension cords rope,
To keep the tension i.e. Suo Li of rope rope, this tension is most important, is the important parameter for guaranteeing bridge security.
Summary of the invention
The purpose of the present invention is to provide a kind of drag-lines that can be realized tonometry.
In order to solve the above technical problems, technical scheme is as follows:
A kind of drag-line can be realized tonometry, fixed anchor plate when including rope rope and using, the end of rope rope is fixed with
Cylinder is supported, bearing cylinder periphery is threaded with adjusting nut, and drag-line further includes the measurement between anchor plate and adjusting nut
Cylinder, measurement cylinder include the cylinder body for being sheathed on the annular of bearing cylinder periphery, offer the plunger shaft filled with hydraulic oil on cylinder body, living
Guiding movement is equipped with the piston rod of the power transmission between anchor plate and adjusting nut in plug chamber, and measurement cylinder further includes for detecting
State the oil pressure sensor of hydraulic fluid pressure in cylinder body.
Plunger shaft and piston rod are ring structure.
Plunger shaft has at least two, circumferentially-spaced arrangement of each plunger shaft along bearing cylinder.
Switch valve is provided on the oil circuit that oil pressure sensor is connected with the plunger shaft.
The switch valve is solenoid valve.
The invention has the benefit that piston rod power transmission between anchor plate and adjusting nut of cylinder is measured in the present invention,
The tension of rope rope passes to fixed anchor plate through bearing cylinder, adjusting nut piston rod, therefore power suffered by piston rod is
The tension of rope rope, and the hydraulic oil pressure measured by oil pressure sensor, can be with according to the forced area of piston rod and hydraulic oil
Easily converse power suffered by piston rod i.e. rope rope tension.
Further, it is provided with switch valve on the oil circuit that oil pressure sensor is connected with plunger shaft, is not required to measurement Suo Shengla
When power, switch valve is closed, and is avoided oil pressure sensor from being pressurized for a long time, is guaranteed the service life of oil pressure sensor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of inhaul cable anchorage structure in background of invention；
Fig. 2 is the structural schematic diagram of one embodiment of the present of invention；
Fig. 3 is the structural schematic diagram that cylinder is measured in Fig. 2.
Specific embodiment
A kind of implementation for the drag-line can be realized tonometry is for example shown in Fig. 2 ~ 3: including rope rope 1, the upper end of rope rope with
Tower is connected, and the lower end of rope rope is connected by inhaul cable anchorage structure with pontic, and inhaul cable anchorage structure includes being fixed on rope rope end
Cylinder 4 is supported, the periphery set sequence for supporting cylinder is arranged with anchor plate 2, measurement cylinder 9 and adjusting nut 3, and wherein anchor plate 2 is with respect to bridge
Body is fixed, and bearing cylinder 4 passes through anchor plate 2 and measurement cylinder 9, and adjusting nut 3 is threadedly coupled with bearing cylinder 4.Measurement cylinder includes being arranged
In offering the plunger shaft 10 filled with hydraulic oil on the cylinder body 5 of the annular of bearing cylinder periphery, cylinder body, plunger shaft 10 is ring junction
Structure, guiding movement is equipped with the piston rod 6 of the power transmission between anchor plate 2 and adjusting nut 3 in plunger shaft, in the present embodiment, cylinder
5 contact of body is on adjusting nut 3, and the end of piston rod is connected with annular slab 7, and 7 contact of annular slab is on anchor plate 2.Measure cylinder
Further include the oil pressure sensor 9 for detecting hydraulic fluid pressure in cylinder body, is set on the oil circuit that oil pressure sensor is connected with plunger shaft
It is equipped with switch valve 8, switch valve is solenoid valve.Switch valve 8 and oil pressure sensor 9 are respectively mounted on a side wall of the cylinder, switch valve 8 with
It is connected between oil pressure sensor 9 by oil pipe.
It is that string has set a survey between anchor plate and adjusting nut for the present invention compares existing inhaul cable anchorage structure
Cylinder is measured, realizes the power transmission between anchor plate and adjusting nut, the stress and rope of such piston rod by measuring the piston rod of cylinder
The uniform tension in order of rope, the oil pressure measured by oil pressure sensor can converse the stress of piston rod easily.It is not needing to rope
When fathom power, valve is turned off the switch, oil pressure sensor is not required to persistently be acted on by oil pressure, and when needing to rope rope dynamometry, opening is opened
Valve is closed, rope rope tension can be measured, stretches out acting due to not needing piston rod, the range of piston rod can control
Very little, such as on the one hand the range of piston rod facilitates the axial length for reducing dynamometry cylinder within 3cm in this way, into
And the cost of manufacture of dynamometry cylinder is reduced, in addition, piston rod bottoms out cylinder body even if there is the case where oil leak, bridge will not be made
At very big destruction, guarantee the safety of bridge.
In other embodiments of the invention: switch valve can also be manual switch valve；Certain plunger shaft may not be
Annular, such as plunger shaft is to be all provided with along the bearing single plunger shaft of cylinder circumferentially spaced at least two, each plunger shaft
It is equipped with piston rod.
