Abstract
The utility model discloses a cable length counter for hydrological cableways, comprising a frame, a counter wheel and a counting encoder, wherein the counting encoder is fixed on the counter wheel arranged on the frame, the frame above the counter wheel is provided with a floating type pressing wheel, the upper end of the frame is provided with a cable diameter adjusting button and a pressing spring is provided between the cable diameter adjusting button and the pressing wheel. The frame comprises two fixing mounting boards respectively provided with a vertical strip chute, wherein two ends of the wheel shaft of the pressing wheel are respectively arranged in the two strip chutes and can move up and down along the strip chutes. The cable length counter has reasonable design, simple structure, accurate measurement, the application for different cable diameters, wide application, low cost and high economic benefits.
Description
One, technical field:
The utility model relates to a kind of utensil of measuring hydrometric cableway rope circuit and the actual displacement of hoisting rope, particularly relates to a kind of hydrometric cableway rope long counter.
Two, background technology:
In important hydrology discharge measurement field, the cableway method is main discharge measurement mode, the measurement of the start point distance in the discharge measurement process (the tangential movement distance of fish lead) and the depth of water (the vertical movement distance of fish lead) all is to obtain by the rope length of computation cycles rope wire rope and hoisting rope wire rope, is to twine rope circuit wire rope and the reel revolution of hoisting rope wire rope and the diameter D of reel by measuring in the general way in national cableway method discharge measurement field at present
1Draw, because the wire rope that twines on the reel is not one deck sometimes, when reel twined the layer of steel wire rope, actual diameter equaled D
1, when reel twined two-layer above wire rope, actual diameter was greater than D
1, because variation has taken place the diameter of the reel that is calculated, will cause the error of calculation, its actual diameter causes computational data less than normal greater than the diameter of reel, finally influences the accuracy of discharge measurement.
Three, utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, the hydrometric cableway that a kind of reasonable in design, simple in structure, accurate measurement is provided and is applicable to collinear footpath not is with the rope long counter.
The technical solution of the utility model is:
A kind of hydrometric cableway rope long counter, contain support, counter wheel and counting encoder, and counting encoder is fixed on the counter wheel, counter wheel is rack-mount, on the support of described counter wheel top floating type contact roller is installed, wired footpath adjusting knob is installed in described support upper end, is provided with holddown spring between this line footpath adjusting knob and the described contact roller.
Described support contains two mounting plates, and is provided with connecting link or web joint between two mounting plates, and the wheel shaft two ends of described counter wheel and contact roller are installed on two mounting plates respectively.
Be respectively arranged with the strip chute of a vertical direction on described two mounting plates, the wheel shaft two ends of described contact roller lay respectively in two strip chutes, can move up and down along the strip chute.
The beneficial effects of the utility model are:
1, the utility model accurate measurement, hydrometric cableway moves between contact roller and counter wheel with rope, the drive counter wheel rotates, be installed in counting encoder on the counter wheel along with counter wheel rotates, because the diameter of counter wheel is known, and be constant, just can calculate hydrometric cableway with having restricted mobile distance by calculating revolution, thereby with regard to having eliminated the defective that causes the error in dipping that vary in diameter causes in original measurement mechanism owing to the reel multiple wraps, improved counting precision greatly like this.
2, the utility model is provided with wired footpath adjusting knob, holddown spring and floating type contact roller, by adjusting line footpath adjusting knob, change the pressure of holddown spring to contact roller, and then the distance between change contact roller and the counter wheel, can adapt to different line footpaths like this, in addition, because the effect of holddown spring, contact roller closely contacts hydrometric cableway with restricting with counter wheel, increased the friction force between hydrometric cableway usefulness rope and the counter wheel, prevent that effectively counter wheel from skidding, the corresponding counting precision that improved.
3, the utility model is reasonable in design, simple in structure, and its critical piece is parts commonly used, is easy to buy and make, and cost is lower.
4, the utility model usable range is wide, especially is applicable to the length metering of hydrometric cableway with rope, has good economic benefit after the popularization.
Four, description of drawings:
Fig. 1 is the structural representation of hydrometric cableway with the rope long counter.
Five, embodiment:
Embodiment: referring to Fig. 1, among the figure, hydrometric cableway contains two mounting plates with the support 7 of rope long counter, and be provided with connecting link or web joint between two mounting plates, the wheel shaft two ends of counter wheel 5 are installed in respectively on two mounting plates, and be fixed with counting encoder 6 on the counter wheel 5, be respectively arranged with the strip chute of a vertical direction on two mounting plates of counter wheel 5 tops, the wheel shaft two ends of contact roller 3 lay respectively in two strip chutes, can move up and down along the strip chute, wired footpath adjusting knob 1 is installed in two mounting plate upper ends, is provided with holddown spring 2 between this line footpath adjusting knob 1 and the contact roller 3.
During use, hydrometric cableway is passed from this device with rope 4, because hydrometric cableway moves between contact roller 3 and counter wheel 5 with rope 4, hydrometric cableway drives counter wheel 5 with rope 4 and rotates, be installed in counting encoder 6 on the counter wheel 5 along with counter wheel 5 rotates, because the diameter of counter wheel 5 is known, and is constant, just can calculate hydrometric cableway with having restricted 4 distances that move by calculating revolution.
For example: zequin is to obtain L-start point distance, D by the rope length of computation cycles rope wire rope apart from (the tangential movement distance of fish lead)
1-counter wheel diameter, N
1The revolution of-counter wheel, L=π D so
1N
1
The measurement of calculating the depth of water (the vertical movement distance of fish lead) is to obtain the H-depth of water, D by the rope length of hoisting rope wire rope
2-counter wheel diameter, N
2-counter wheel revolution, H=π D so
2N
2
By adjusting line footpath adjusting knob 1, change the pressure of 2 pairs of contact rollers 3 of holddown spring, and then change the distance between contact roller 3 and the counter wheel 5, just can adapt to the not hydrometric cableway rope circuit 4 in collinear footpath.Annexation between the concrete structure of change support, change line footpath adjusting knob, holddown spring and the floating type contact roller and the annexation that changes between counter wheel and the counting encoder can be formed a plurality of embodiment, be common variation range of the present utility model, do not describe in detail one by one at this.
