Abstract
The utility model relates to a device which can control a cable to have unidirectional movement freely, comprising a bracket, a belt wheel and an eccentric wheel. The belt wheel is connected with the bracket through a pin, and the eccentric wheel which is connected with the bracket through the pin is arranged on the belt wheel. The eccentric wheel is provided with teeth which are contact with the cable on the belt wheel, a torsion spring is provided on the pin, and the head part of the torsion spring presses the eccentric wheel which is pressed on the belt wheel intensively. The rigging gear of the utility model has simple structure, beautiful appearance, convenient using and high positioning accuracy, and the utility model can realize inching control.
Description
Affiliated technical field
The utility model relates to a kind of rope and leads the instrument of carrying, the particularly a kind of device that can control the rope one-way movement arbitrarily.
Background technology
The lifting of article and translation generally need be led with rope and be carried, and rope leads and carries general use pulley at present, but need sometimes do unidirectional control to the motion of rope, and this just needs to finish with rigging.Original rigging is by support, belt wheel, bearing pin is formed, rope is on belt wheel and pass the bearing pin groove, cw pulling rope, bearing pin can't be rotated by support control, rope is stuck in the bearing pin groove, rope is clockwise can not to move, when conter clockwise pulling rope, but bearing pin is left-hand revolution also, and rope can slide arbitrarily in the groove of bearing pin, and rope can stretch in the counterclockwise direction, because the groove of bearing pin has certain length, when conter clockwise stretches rope within it the position of portion be uncertain, rope also is an exactness not in slippage when locked, so accuracy of positioning is not high.
Summary of the invention
In order to overcome the not high deficiency of existing rigging accuracy of positioning, the utility model provides a kind of accuracy of positioning height, also can realize the rigging that crawl is controlled.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of rigging, form by support, belt wheel, eccentric wheel, belt wheel is connected by pin with support, eccentric wheel is arranged on the belt wheel top, is connected by pin with support, and eccentric wheel is provided with tooth, tooth contacts with rope on the belt wheel, also be provided with torsion spring on the pin, the torsion spring head is pushed down eccentric wheel, and eccentric wheel is pressed on the belt wheel.
When cw pulling rope, pulling force can overcome torsion spring power lifts eccentric wheel slightly, rope can slide arbitrarily, when conter clockwise pulling rope, the direction of pulling force is consistent with the direction of torsion spring power, the combined action of two power presses down eccentric wheel, and rope is tightly pushed down by eccentric wheel, so the anticlockwise direction rope can not move.
The beneficial effects of the utility model are that simple in structure, handsome in appearance, easy to use, the accuracy of positioning height can be realized crawl control.

1. supports among the figure, 2. belt wheel, 3. pin, 4. eccentric wheel, 41. teeth, 5. pin, 6. torsion spring.
The specific embodiment
As Fig. 1, original rigging shown in 2, by support, belt wheel, bearing pin is formed, rope is on belt wheel and pass the bearing pin groove, cw pulling rope, bearing pin can't be rotated by support control, rope is stuck in the bearing pin groove, rope is clockwise can not to move, when conter clockwise pulling rope, but also left-hand revolution of bearing pin, rope can slide arbitrarily in the groove of bearing pin, rope can stretch in the counterclockwise direction because the groove of bearing pin has certain length, when conter clockwise stretches rope within it the position of portion be uncertain, rope also is an exactness not in slippage when locked, so accuracy of positioning is not high.
Rigging of the present utility model shown in Fig. 3,4, form by support 1, belt wheel 2, eccentric wheel 4, belt wheel 2 is connected by pin 3 with support 1, eccentric wheel 4 is arranged on belt wheel 2 tops, is connected by pin 5 with support 1, and eccentric wheel 4 is provided with tooth 41, tooth 41 contacts with rope on the belt wheel 2, also be provided with torsion spring 6 on the pin 5, the torsion spring head is pushed down eccentric wheel 4, and eccentric wheel 4 is pressed on the belt wheel 2.
When cw pulling rope, the pull strap movable eccentric wheel 4 of rope overcomes torsion spring power to be rotated eccentric wheel 4 and lifts slightly, because the off-centre of eccentric wheel 4 has been given the space of rope slip, this moment, rope can slide arbitrarily along this direction, when conter clockwise pulling rope, the direction of pulling force is consistent with the direction of torsion spring power, and the combined action of two power presses down eccentric wheel, the anticlockwise direction rope rope tightly pushed down, so can not move by eccentric wheel 4.
