Shown in Fig. 4, solar power supply apparatus 8 can be lasing light emitter 7, and signal feedback plate 10 and signal projector 21 provide work energy.Lasing light emitter adopts commercially available conventional laser transmitter, and as red laser pen or similar device, its power consumption is little, and cost is low.
Above-mentioned Laser emission frequency, the temporal frequency of signal feedback plate output signal and signal projector transmitted signal etc. has manipulated by the control circuit of prior art, and the utility model only provides hardware configuration setting.
Shown in Fig. 5, in four concrete column foots 1 of steel tower, be separately installed with lifting oil cylinder 2, the oil pipe 3 of lifting oil cylinder leads in base 5, in base 5, is provided with hydraulic station device, and oil pipe 3 is connected with the respective line of hydraulic station device.By-pass valve control is all housed on every bye-pass.Base 5 surfaces are fixed reflector 6 by adjusting bolt 4.Described reflector adopts level crossing or similar device.
Hydraulic schematic diagram shown in Fig. 6, represents be placed in lifting oil cylinder 2 in different concrete column foots by hydraulic station device control and lifting power is provided.Described hydraulic station device comprises control template, fuel tank, and motor, high-pressure oil pump and pipeline etc., be routine techniques and equipment.
Shown in Fig. 7-9, in concrete column foot central upper portion axial location, be provided with lifting oil cylinder 2, the oil pipe 3 of described lifting oil cylinder 2 is drawn through oil pipe passage 15.Described oil pipe 3 comprises oil inlet pipe 13 and oil return pipe 14.
Figure 10 is the K portion enlarged drawing of Fig. 9, while building steel tower concrete column foot 1 shown in figure, do circular cavity 19 at each column foot basal plane center model, do a fixing steel cylinder 18 and be placed in cavity 19 with the steel plate of 10 millimeters thick, or will fix steel cylinder and put into after cavity design attitude directly moulding by casting as evacuated mould.Cavity upper opening center overlaps with column foot 16 bottom vertical center lines, according to tower body weight, the lifting oil cylinder 2 of corresponding tonnage is placed in respectively in the steel cylinder 18 under each column foot.In the time of pour concrete column foot, a default steel pipe being communicated with outside is as oil pipe passage 15, the fixing steel cylinder bottom opening of the inner port of this steel pipe and cavity 19() bottom is communicated with, the oil pipe 3 of lifting oil cylinder 2 comprises oil inlet pipe 13 and oil return pipe 14, and described oil inlet pipe is extended in base 5 and is connected with the corresponding oil pipe of hydraulic station device by this oil pipe passage 15 with oil return pipe.State when left side column foot 16 represents not to be lifted in figure, column foot 16 expressions in right side by the state after piston rod 17 liftings of oil cylinder 2, have been placed cushion block 20 between the column foot bottom after lifting and concrete column foot.
Detect with lifting (correction) operation process as follows:
When steel tower normally moves, regularly Emission Lasers bundle of the lasing light emitter 7 on it is radiated in the a-quadrant of signal feedback plate 10 after the baffle reflection of bottom, and signal projector sends normal alarm signal.In the time of steel tower run-off the straight, laser reflection signal point of irradiation exceeds a-quadrant and enters in B region, light-sensitive material in B region is subject to exciting the generation signal of telecommunication, and control circuit makes signal projector send inclination alarm signal, reminds the staff of control centre to keep a close eye on this tower-like condition.In the time that steel tower knockdown meets or exceeds code requirement, return laser beam is irradiated in C region, after being excited, the light-sensitive material that is positioned at this region sends signal pulse to signal projector, to control room, staff sends emergency alarm, sends the work person of being to go to field to reconnoitre and proceed as follows:
(1) first adopt portable level instrument to check reflector level, if any inclination, be adjusted to level by adjusting bolt; Lasing light emitter switch is adjusted into continuous emission state, observe the position of reflection light point on signal feedback plate, preliminary determine Iron tower incline direction and according to the position judgment inclined degree of above-mentioned reflection light point, then determine Iron tower incline number of degrees value by apparatus measures, require if tilt to exceed standard license, allocate and transport portable power generation unit to on-the-spot, conventionally have diesel generating set for subsequent use.
(2) determine and need of lifting or two column foots and unclamp column foot set bolt according to incline direction;
(3) oil inlet pipe of column foot bottom lifting oil cylinder of lifting and the valve open of oil return pipe will be needed;
(4) start hydraulic station device/system works, lifting oil cylinder rising by column foot lifting, in lifting process, be encased inside ready column foot cushion block, observe lasing light emitter folded light beam motion track simultaneously, when described folded light beam moves to signal feedback plate central area or represents that this column foot lifting puts in place, closes hydraulic system power when neighbouring;
(5) check that column foot bottom cushion block meets after complete standard, hydraulic system release;
(6) tower stud is fastening, this place's column foot lifting task completes;
(7) position on signal feedback plate according to folded light beam, judges whether also to exist the inclination of all the other column foots, and determines whether to proceed lifting operation.
The hydraulic jack that above-mentioned operation can start two column foots simultaneously carries out lifting operation.Or two column foots replace lifting, in place to guarantee rapid lifting.
Sensitiveness when this device utilizes light to propagate in certain distance, light source slightly being moved, as the auxiliary monitoring device of Iron tower incline, there is very high sensitivity, according to site trial, even if 0.1 degree or the displacement of 1 centimetre occurs light source, on signal feedback plate, just have very clear and definite demonstration.Therefore as a kind of auxiliary particularly early stage Iron tower incline monitoring warning device, simple in structure because of it, with low cost, highly sensitive and there is fabulous application prospect.
