Background technology
Main push-towing rope is the main load-carrying construction of suspension bridge, and every main push-towing rope is mostly made of up to a hundred parallel wire unit stocks, these are high
Strong steel wire is ranked sequentially by regular hexagon according to design；In order to ensure the relative position relation and design of each steel tendon stock
Unanimously, it needs to measure the relative position between each stock cable wire and basic cable wire；And since the plan-position of each rope can be by the lock of king-post
Hole is fixed, therefore only needs to measure the height difference between every cable wire and basic cable wire；Again phase is adjusted by tensing or loosening cable wire
To height difference, all cable wires is made all mutually to be in design position.
And the method for traditional measurement cable wire relative elevation or opposite sag is the vernier calliper by using similar scale-up version
Ruler device carries out manual measurement and reading；Although this method low cost, disadvantage are many；First, it cannot be guaranteed slide calliper rule
Cross bar is horizontal, and causes the opposite sag for measuring two cable wires bigger than actual value；Secondly, this method needs artificial reading,
Difficulty of this method relative to high-altitude application is increased, and introduces error in reading；Furthermore this method is unsatisfactory in engineering round the clock
The property of continuous work；Operation is extremely inconvenient when night use.

Be arranged in montant lower end and perpendicular bottom bar；Further include that the level slided along montant parallel with bottom bar is horizontal
Bar；It is provided with displacement sensor for pull rope below bottom bar, displacement sensor for pull rope outlet end is fixed on water across bottom bar
On flat cross bar；Bottom bar upper surface is provided with the first levelling tube, and horizontal cross bar upper surface is provided with the second level pipe.
Further, the displacement sensor for pull rope connects display device.
Further, the montant is provided with two, and two montants are mutually parallel；Two montant upper ends are connected by connecting rod
It connects.
Further, fixed plate is provided with below the bottom bar, displacement sensor for pull rope is arranged in fixed plate.
Further, the display device is arranged in auxiliary tank；Display device connects battery pack by power inverter.
Further, through-hole is provided on the horizontal cross bar, montant passes through through-hole；Horizontal cross bar is sleeved on montant；
Lead to the hole site is corresponded on horizontal cross bar is provided with fixing device.
The utility model has the beneficial effects that：
(1) it is measured with respect to sag by draw-wire displacement sensor in the utility model, bottom transverse is made by levelling tube
Bar and horizontal cross bar are in horizontal, high certainty of measurement, and data are accurate；
(2) the utility model connect display, need not manually read, measure operation can carry out round the clock, and night into
Row is convenient to；
(3) the utility model is easy to operate, precision is high, measurement data is visual, can reduce the amount of labour of worker, increases night
The safety coefficient of work.
