Abstract
The utility model relates to a three-pulley force transducer, which comprises a pulley yoke. The pulley yoke is connected with a universal joint. Three pulleys are installed on the pulley yoke. A shaft pin type transducer is arranged on the central pulley. The three pulleys are made of nylon. By adopting the structure that three pulleys are installed on the pulley yoke, the utility model has the advantages that the assembly and the disassembly of the entire transducer are convenient, the replacement is easy and the total weight of the device is reduced; the universal joint is used to adjust the position of the three pulleys, the position of the entire device can be changed within a range of 180 degrees and the device can adapt to the jump and the swing of the steel wire rope; the high-strength nylon pulleys are adopted, the weight is decreased and the wear on the steel wire rope is reduced.
Description
Technical field
The utility model relates to a kind of force cell, and particularly a kind of employing wire rope forms certain angle by three pulleys, and pulley is produced the three pulley force cells that certain pressure comes the suffered pulling force of measuring steel wire rope.
Background technology
How the measuring steel wire rope is stressed in crane and the hoisting device is to the hoisting device overall security, the important prerequisite that reliability is judged, at existing several main force cells, as the bearing seat formula, side-compression, the plate ring is pull-type, pillar, axial pin type etc., all there are some objective condition to limit its range of application during use, bearing seat is that requirement gear reduction unit one side has the axle housing support, side-compression and plate ring are pull-type to require wire rope winding place that not running rope must be arranged, pillar requires just to reserve the power taking space in advance in hoisting device design formula, and pivot pin then requires the fixed pulley size can not be excessive, though more than several sensors its advantage is respectively arranged, but in the process that existing some hoisting devices that use are transformed, a considerable amount of these several power taking modes that all can't adopt of hoisting device of producing about past 10 years are carried out power taking, simultaneously more present hoisting devices such as pedrail crane, harbour door machine etc., because design itself also is difficult to use above these several power takeoffs.
Summary of the invention
The purpose of this utility model is to provide a kind of overall dimensions small and exquisite, easy for installation, and commutation ability is good, adapts to wire rope and jumps, swing, the three pulley force cells that the dynamometry accuracy is high.
The purpose of this utility model is achieved in that a kind of three pulley force cells, comprises pulley yoke, and pulley yoke is connected with universal joint, and three pulleys are installed on the pulley yoke, and the pulley at middle part is provided with the pivot pin sensor.Pulley adopts nylon to make.
The three pulley force cells that the utility model provides, because three pulleys of employing are installed in the structure on the pulley yoke, the whole sensor easy installation and removal is easy to replace simultaneously, has alleviated the overall weight of equipment; Adopt universal joint to regulate three pulley orientation, whole device can change arbitrarily in 180 degree scopes, adapts to wire rope and jumps, swing; Employing high-strength nylon wheel has not only alleviated weight, has reduced the wearing and tearing to wire rope simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a power taking synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises pulley yoke 1, and pulley yoke 1 is connected with universal joint 4, and three pulleys 2 are installed on the pulley yoke 1, and the pulley 2 at middle part is provided with pivot pin sensor 3.Pulley 2 adopts nylon to make.
When the utility model used, as shown in Figure 2, wire rope 5 passed between the pulley at two pulleys in top and middle part, can carry out dynamometry by pivot pin sensor 3, by universal joint 4 pulley yoke 1 can be changed in 180 degree scopes arbitrarily, jump swing to adapt to wire rope.
Claims (2)
