Description
technical field:
The utility model relates to building structure field, particularly relates to a kind of device measuring drag-line horizontal displacement of foundation.
background technology:
In recent years, various engineering construction speed is accelerated, and the Foundation Design for large-scale lifting and rapid transit increases.Because the displacement state of force structure relates to engineering safety, directly affect construction, the personal safety of staff, have to carry out Real-Time Monitoring to some force structures, prevent engineering accident from occurring.As the cable rope basis of extra-high gate-type portal frame, Construction of Pylon of Long Span Suspension Bridge drag-line basis is owing to being subject to the effect compared with large horizontal force, may occurred level displacement under the effect of horizontal force, reduce cable rope to the effect of contraction of agent structure, make portal frame there is potential danger.
The horizontal movement of current measurement architecture basics is more is sight gauge algorithm, and certainty of measurement is by human factor, and such environmental effects is comparatively large, and precision not easily meets the demands.
utility model content:
The purpose of this utility model is to solve the problem, the device of a kind of precise and stable real-time measurement drag-line horizontal displacement of foundation of proposition.
The technical solution adopted in the utility model is: a kind of device measuring drag-line horizontal displacement of foundation, comprises displacement trailer system, displacement converting system and measuring system; Displacement trailer system comprises base, trussed shore, suspension column support and draught line, and displacement converting system comprises weight, measures pedestal and pedestal, and measuring system comprises displacement meter, tilt meter and Magnetic gauge stand; Described measurement pedestal is fixed on pedestal, measure pedestal to be made up of pedestal framework and diagonal brace, pedestal framework is arranged on pedestal, the top of pedestal framework is provided with fixed pulley, and middle part is provided with fixing bucket, and draught line one end is connected with the top of trussed shore, the other end is connected with weight by fixed pulley, bottom weight, be provided with displacement meter, Magnetic gauge stand is clamped on displacement meter, and is placed on bottom measurement pedestal.
Further, described tilt meter is arranged on trussed shore side.
Further, in measurement drag-line horizontal displacement of foundation device, be also provided with information acquisition system, described information acquisition system comprises strain gauge, data acquisition line concentration and computer.
The beneficial effect that the utility model produces is: the utility model can convert vertical displacement to horizontal movement effectively, and remote capture displacement structure information, greatly improves the possibility of survey crew security measurement; Consider basic corner displacement to compensate, decrease the size that basic corner causes measuring result error, accurate further measurement result; Easy technician, when convenient construction, measure error controls, within 1.25 ‰, strictly to meet the precision of engineering structures displacement.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation measuring pedestal;
Fig. 3 is the lateral view measuring pedestal.
detailed description of the invention:
This is further described the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the displacement trailer system of the utility model device is connected with basis 12, and base 11 is made up of steel plate, is connected with basis 12 with setscrew; Trussed shore 8 is made up of concrete filled steel tube, and nominal diameter of steel pipe is about 50mm, if trussed shore is long, then suitably increases nominal diameter of steel pipe.Trussed shore 8 welds with base 11 and uses Φ 25 reinforcement welding suspension column to support 10, bottom trussed shore 8, form three trivets, and in steel pipe, placing plain concrete ensures the rigidity of trussed shore 8, prevents trussed shore 8 from producing dynamic error because external environment causes vibrations.It is draught line 7 that the boring of trussed shore 8 top is used for wearing, and clamps draught line 7 prevent draught line 7 slippage from causing measure error with steel stranded wire clamper.
Displacement trailer system converts horizontal movement to vertical displacement by displacement converting system.As shown in Figures 2 and 3, displacement converting system is made up of weight 3, measurement pedestal 5 and pedestal 6.Draught line 7 is walked around and is measured fixed pulley 4 on pedestal, penetrates weight suspension ring, steps up draught line 7 with fixture.Pedestal framework 13 adopts stainless steel steelframe, is placed on pedestal 6 and fixes with setscrew 16, be provided with diagonal brace 14 bottom pedestal framework 13.The each rod member of steelframe adopts stainless steel rectangular steel tube, rectangular steel tube length of side 30mm to 40mm; Measuring on pedestal has weight to fix bucket 15, fixes the diameter of diameter slightly larger than weight 3 of bucket 15.Fixing bucket 15 is elevated for guiding weight 3, and the lifting behavior of specification weight 3, prevents weight 3 from rolling.Measure bottom welding one deck steel plate of pedestal 5, be convenient to Magnetic gauge stand 1 and adsorb fixing.Measure a reserved setscrew hole respectively, corner, bottom of pedestal 5, for setscrew, pedestal is fixed to pedestal, prevent measuring pedestal 5 and moved by the horizontal pull of draught line 7 or topple.Pedestal 6 is built by plain concrete and is formed, surfacing, can be easy to fixation measuring pedestal 5, and can keep measuring pedestal 5 level.
Measuring system is arranged on to be measured on pedestal 5, and Magnetic gauge stand 1 clamps displacement meter 2, is adsorbed on and measures on pedestal 5.Displacement meter 2 thimble withstands weight 3, and thimble length can be determined according to the basic displacement direction judged in advance.As shown in Figure 1, if basis 12 is moved to the left, only weight 3 need be allowed just to push down thimble, suggestion weight 3 is pushed down thimble and is moved down a bit, prevents because weight 3 comes to nothing and produces error; If basis 12 moves right, then need to allow weight 3 that thimble is pressed onto the end, without the need to completely on earth, produce error to prevent because draught line 7 is relaxed.Because basis 12 occurs to cause trussed shore 8 top that larger horizontal movement occurs when slightly tilting, therefore correct basic 12 horizontal movements with tilt meter 9.The small pieces that polish flat on trussed shore 8 side are local, and by tilt meter 9 base stick on top, tilt meter 9 is put into base 11 and fixed.
Information acquisition system comprises data acquisition line concentration, strain acquirement instrument and computer.Displacement meter 2 is connected by data acquisition line concentration and strain acquirement instrument with tilt meter 9, and strain acquirement instrument is connected with computer by usb Serial Port Line, manipulates strain acquirement instrument collection and store data by computer.
