Abstract
The invention relates to a depth tester for a water lifting platform. The depth tester comprises a shell, a drive pulley, a reverse wheel, a coil spring winding wheel, a coil spring starting wheel, pinch rollers, a rotary encoder and a calculating unit, wherein the first end of a coil spring is fixed on the coil spring starting wheel, the second end of the coil spring is fixed on the coil spring winding wheel, and the main body part of the coil spring in an initial state is wound on the coil spring starting wheel; each pinch roller is pressed against the surface of a drive belt on the reverse wheel; the rotary encoder is used for measuring the revolution signal of the reverse wheel; and the calculating unit is used for calculating the lifting depth of the water platform through data exchange and is in signal connection with the rotary encoder. A synchronous belt and a toothed belt pulley are meshed so as to achieve drive leakproofness and eliminate drive interval caused by slip; and two pinch rollers which are pressed against the surface of the synchronous belt on the reverse wheel are arranged in the shell, so that the bounce of the synchronous belt during operation is avoided, the belt and the pulley are ensured to be fully meshed and the test accuracy is improved.
Description
(1) technical field
The present invention relates to the depth tester of stage technical field, particularly a kind of water-stage.
(2) background technology
General performance stage all is arranged on the land, and this stage need occupy certain geographical space, even if do not perform, also needs to occupy certain place.In order to address the above problem, developed water-stage at present, under obsolete situation, this stage can be hidden, avoid the space waste.In the performance process, in order to satisfy the story of a play or opera, need to regulate the concrete degree of depth of dried up of stage, adopted the test of stay-supported scrambler in the past, scrambler drives with wire rope, and generation slippage easily between the rope sheave that wire rope and drive scrambler mandrel rotate, produce transmission intermittently, because of being difficult to drive closely the rope sheave rotation, make the discontinuous rotation of scrambler mandrel and cause signal to send intermittently, then produce the error that test value and backguy value do not wait, simultaneously, it also is that other end system by same wire rope comes transmission with the lower pulling force that weight produces that the counter-rotating of scrambler mandrel resets, and this equally also is easy to generate slippage, the capital causes the generation of error, has had a strong impact on the degree of accuracy of test value.It also needs the stroke up and down that weight is satisfied in higher installation site, not only takes up space but also inconvenience is installed.
(3) summary of the invention
In order to solve the shortcoming that there is error in existing water-stage MTD, takes up space and installs inconvenience, the invention provides a kind of depth tester of water-stage, reach the tightness of transmission by engagement by synchronous band and profile of tooth belt wheel, eliminated the transmission intermittence that produces because of slippage, and adopt the thin material wind spring as the power that resets after band is drawn out synchronously, synchronous band is drawn outside and when involute and the profile of tooth belt wheel all realized tight transmission very, not only significantly improve the precision of test, also made things convenient for installation simultaneously.
For this reason, the present invention takes following technical scheme:
A kind of depth tester of water-stage comprises the housing that accommodates driving-belt; Drive pulley and reverse wheel rotatably are fixed on respectively in the housing, and first end of driving-belt connects also and is wound on the drive pulley, and second end is walked around and passed housing behind the reverse wheel and be connected with water-stage; Wind spring twines wheel and wind spring initial wheel, described wind spring twines wheel and is fixedly mounted on the wheel shaft of drive pulley, described wind spring initial wheel rotatably is fixed in the housing, first end of wind spring is fixed on the wind spring initial wheel, second end is fixed on wind spring and twines on the wheel, the wind spring of original state, main part are wrapped on the initial wheel of wind spring; Pinch roller rotatably is fixed in the housing, offsets with driving-belt zone face on the reverse wheel; Also comprise the rotary encoder that is used to record reverse wheel revolution signal, described rotary encoder is fixedly mounted on the housing outer wall, the rotation mandrel of rotary encoder and the coaxial socket of reverse wheel wheel shaft, rotation synchronously; Comprise that also one is used for the computing unit that exchanges data is calculated the water stage lifting degree of depth, described computing unit is connected with described rotary encoder through signals.
Further, described driving-belt is to be with synchronously; Described drive pulley and reverse wheel are the profile of tooth belt wheel that cooperates with it.
Further, described pinch roller is two, is arranged symmetrically in two positions in reverse wheel wheel week.
Depth test principle of the present invention a: because end of band spurs the profile of tooth belt wheel with stage lifting in the water synchronously, the mandrel that this belt wheel drives scrambler rotates, scrambler sends rotation information to computing unit, diameter as belt wheel is D, then synchronously band to drive turn around 360 ° pulling length of profile of tooth belt wheel be D * π (π is a radian) or 2 π * r (r is a radius), and arc length L=r arbitrarily * α (α is a radian), can on the screen of computing machine, obtain instantaneous test value by computing unit, if it is thin more that the circumference radian is got, the lifting value precision of stage is just high more in the water.
Employing the present invention have the following advantages: 1, reach the tightness of transmission by the engagement by synchronous band and profile of tooth belt wheel, eliminated the transmission intermittence that produces because of slippage; 2, adopt the thin material wind spring as the power that resets after band is drawn out synchronously, synchronous band is drawn outside and when involute and the profile of tooth belt wheel all realized tight transmission very, not only improved the precision of test, spurred the needed stroke up and down that resets but also deducted in the past by weight, reduced occupying of space, provide convenience installing and using; 3, be provided with in the housing two with reverse wheel on the pinch roller that offsets of synchronous band zone face, row is imitated and has been avoided synchronous band beating when operation, has guaranteed the abundant engagement of band and wheel, has improved accurate testing.
