Abstract
A three-rod multi-supporting type tension measuring method relates to a three-bar type tension measuring method. In the measuring part of a measuring device, a plurality of fixing bars used for fixing are arranged above an upper measuring bar and at the two sides of a lower measuring bar; a plurality of groups of tension sensors are respectively arranged on the measuring bars according to types; a rope tension measuring principle is like the three-bar type tension measuring method and only a compensation calculating method needs to be corrected.
Description
Technical field
Tension measurement physical construction computing method
Background technology
Traditional rope pull measuring method generally adopts photostat to measure, or mechanical threshold values judges that performance is relatively poor relatively on precision, and price with improve and significantly increase with precision, be unfavorable for the utilization and the popularization of rope pull measurement.
Summary of the invention
The present invention is directed to the deficiency of existing rope pull measuring method technology, designed a kind of integrated sensor technology, Machine Design, computing method, the measuring method of tensile force of electronic technology has realized that low-cost and high-performance measures the function of rope pull.
Description of drawings
This figure is the structural drawing of this method.
Embodiment
Three-bar multi-support type tension measurement method is a kind of three thick stick type measuring method of tensile force, in the measure portion of measurement mechanism, measuring both sides under the thick stick on the last measurement thick stick and down, is respectively equipped with the fixedly thick stick of some fixations; Measure on the thick stick and be provided with some pulling force sensors by type; The rope pull measuring principle is as three thick stick type measuring method of tensile force, and only compensating computing method need revise.
This measurement mechanism special construction design outside is fixed left-right symmetric framework, can form vertical axis of symmetry; Framework inside is provided with three and measures thick sticks, wherein up and down two measure the same side that thick stick is fixed in framework, measure thick stick and be fixed in the framework opposite side for middle one; Three on-fixed ends of measuring thick stick all are equiped with pulley; Rope passes around the pulley of upper, middle and lower three thick sticks successively; Measure the thick stick extension position up and down and just make critical contact that rope walks around pulley up and down respectively on the vertical axis of symmetry of framework, formed error can be ignored, and wherein critical contact finger is crossed rope and the critical point that contacts of pulley;
Fixedly the thick stick position is positioned to measure on the thick stick and down and measures both sides under the thick stick, and quantity is respectively several; Fixedly thick stick can make rope pass through vertical axis of symmetry, and formed error can be ignored.
Three thick stick type measuring method of tensile force refer to three bar single order type tension measurement method or one of three bar difference type tension measurement method or three bar difference type tension measurement method or the organic assembling of method wherein.
Since measure rope in both sides by relative fixed, so its certain side error value is less, the modification method correction that must press multi-support type; And fixedly the measured value of thick stick upper pulling force sensor adds corrected Calculation.
