Abstract
The utility model relates to an opening and closing synchronous detection device for a gate, which belongs to the technical field of the horizontal measurement, and is composed of a laser horizontal sensor, and a left and a right laser receivers, wherein, the laser horizontal sensor is arranged on the symmetrical centre line of a gate; the left and the right laser receivers are correspondingly arranged at both sides of the gate; a power line of the laser horizontal sensor is electrically connected with a valve group of an oil pump room. According to the different inclined values of the endpoints of the gate, which are received by the left and the right laser receivers, the different oil drain amount and the oil intake amount of a left and a right oil cylinders are adjusted for realizing the synchronization of two oil cylinders and ensuring that the height difference of the top part of the gate is lower than 10 millimeters. The horizontal is basically kept without skewness.
Description
The utility model is a kind of detecting equipment for synchronous opening and closing of sluice gates, belongs to the horizontal survey technical field.When being particularly useful in the hydraulic engineering revealing the top gates of segmental shape the keying horizontal synchronization measure.
Revealing the top gates of segmental shape is remittance flood facility main on the Hydraulic and Hydro-Power Engineering, and along with increasing of large water conservancy hydroelectric engineering, the open/close machinery that reveals the top gates of segmental shape adopts the also more and more of hydraulic headstock gear.Hydraulic headstock gear opens and closes gate and promotes or transfer gate by two oil cylinders, but will reach the strict synchronism of two oil cylinders, and this is than difficulty.For making gate steadily lifting in opening-closing process, must keep the level on door top, and not appear at left-leaning right oblique phenomenon, two point height differences are not more than 10 millimeters about fitness for purpose gate top.Abroad in design and practice, still be difficult to accomplish at present.This at first will solve the detection means of the asynchronous value of two oil cylinders, according to nonsynchronous detected value, by the size of proportion electro-magnet modulated pressure valve oil inlet or oil outlet, to reach the synchronous of two oil cylinders.So asynchronous accuracy of detection height, two oil cylinder synchronization accuracies are also high.That is just more difficult but obtain the asynchronous detected value of high precision.
Have plenty of in the known technology at piston rod subscript scale, on piston rod, be coated with ceramic protective layer again, and at the front end sensor installation of hydraulic actuating cylinder.The stroke of oil cylinder piston bar, the position that goes out piston rod by the most degree carved on the piston rod and sensor measurement.The advantage of this measuring system is no mechanical transmission device such as gear, a steel rope etc. between piston rod and the sensor.This device records in practice that two point height differences are 17 millimeters about the gate top.This is because this device is not that directly to measure about the gate top two point heights poor according to one's analysis, but there is bigger error the position of measurement piston rod between the two.This sensor measuring system also has than mistake itself in addition, and two point height differences are no more than 10 millimeters requirement about the gate top so be difficult to satisfy.The disadvantage of this cover oil cylinder synchronized measurement system is the expense costliness simultaneously, because must buy the piston rod oil cylinder that the said firm is coated with pottery; Also has plenty of the employing displacement pickup.Be oil cylinder piston bar when moving,, drive displacement pickup and rotate, thereby record oil cylinder piston bar miles of relative movement as steel cable, gear, roller by mechanical drive.The advantage of this method is that cost is low, shortcoming is low precision, and precision was poorer when especially stroke was big; Also have other as by measuring the oil mass of turnover oil cylinder, be converted into piston rod stroke etc., the error of these methods is bigger.
The purpose of this utility model provides a kind of detecting equipment for synchronous opening and closing of sluice gates.Use this device can guarantee that headstock gear makes gate maintenance level when opening and closing gate and not crooked.
Just should aim at detected object the levelness of gate according to this purpose of the present utility model, be about to the object that hydraulic headstock gear detects with department in the step, change the levelness that detects gate into by detecting the oil cylinder piston bar.And the discrepancy in elevation that requires headstock gear door when opening and closing gate to push up 2 left side points and the right point is not more than 10 millimeters at least.The utility model realizes that the solution of this purpose is, a kind of detecting equipment for synchronous opening and closing of sluice gates is provided, it includes sensor (2), left laser pickoff (1) and right laser pickoff (3), described sensor (2) is the laser level sensor, the laser level sensor device on the symmetrical center line of carrier, above-mentioned left laser pickoff (1) and right laser pickoff (3) respectively successively corresponding intrument on the carrier of the and arranged on left and right sides of laser level sensor (2).Promptly install on the crossbeam of gate both sides the laser level line that corresponding laser level sensor (2) two ends of receiving port line of centers of wherein left laser pickoff (1) and right laser pickoff (3) are taken place.The power lead of laser level sensor props up hinge by gates of segmental shape and guides to oil pump room and valve group electricity connects.Because the laser that the laser level sensor sends is level all the time, when the gate run-off the straight, the numerical value difference that left and right laser pickoff received.According to this different numerical value, adjusting different amount of draining the oil of left and right two oil cylinders or oil inlet quantity, can to reach left and right two oil cylinders that reveal two ends, the gates of segmental shape left and right sides, top synchronous.This synchronous detecting precision can reach 2 millimeters, even add that therefore the influence of various other factorses also can reach the gate top inclination discrepancy in elevation fully and be no more than 10 millimeters designing requirement.Above-mentioned left and right two different numerical value that laser pickoff received show in the centralized operation chamber that all the difference of two values is the asynchronous value of hydraulic headstock gear.Simultaneously use a precision lower again, low-cost roller type displacement pickup is surveyed the oil cylinder piston throw of lever, shows gatage.This solution low price, buying is easy, reliable operation.
Below in conjunction with the accompanying drawing illustrated embodiment the utility model further is illustrated.
Accompanying drawing is detecting equipment for synchronous opening and closing of sluice gates structure and carrier gate assembling scheme drawing.
In the accompanying drawing,
The right laser pickoff 4-of 1-left side laser pickoff 2-laser level sensor 3-gate
With reference to accompanying drawing, the detecting equipment for synchronous opening and closing of sluice gates of present embodiment takes a laser level sensor and two laser pickoffs are left and right laser pickoff, wherein, go up the symmetrical center line place of girder at gate (4), laser level sensor (2) is installed, in the left side of laser level sensor (2) left laser pickoff (1) is installed, right laser pickoff (3) is installed on the right side.The laser head of the corresponding in opposite directions laser level sensor of receiver hole (2) of left side laser pickoff (1) and right laser pickoff (3).The power lead of laser level sensor props up hinge by gates of segmental shape and guides to oil pump room and valve group electricity connects.This detecting equipment for synchronous opening and closing of sluice gates synchronous detection door of present embodiment pushes up left and right trueness error at 2 and is not more than 5 millimeters.If be used for less engineering, also can select for use precision lower, be centesimal pressure sensor as precision, cost will be lower like this, synchronization accuracy also can meet the demands.
