Abstract

The invention discloses a two-bar tensile force measuring method, which is a special three-bar tensile force measuring method. In a measuring part of a measuring device, the opposite side of a measuring bar of an upper measuring bar and a lower measuring bar is provided with a plurality of fixing bars for fixing; the measuring bars and the fixing bars are provided with a plurality of tensile force sensors according to types; and the rope tensile force measuring principle is like the three-bar tensile force measuring method, and only a compensation calculation method needs to be corrected.

Description

Two-bar tensile force measuring method

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

Two-bar tensile force measuring method is a kind of three special bar tensile force measuring methods, in the measure portion of measurement mechanism, at last measurement thick stick or measure the offside of a certain measurement thick stick among the thick stick down, is provided with the fixedly thick stick of some fixations; Measure thick stick and fixedly be provided with some pulling force sensors by type on the thick stick; 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, and wherein two thick sticks are fixed in the same side of framework up and down, and the opposite side that thick stick is measured in the top also be arranged in parallel and one measures thick stick, and middle thick stick is fixed in the framework opposite side; The on-fixed end of four measuring thick stick all is equiped with pulley; Rope passes around the pulley of upper, middle and lower three thick sticks successively; The thick stick extension position of measuring up and down of homonymy just makes critical contact that rope walks around pulley up and down respectively on the vertical axis of symmetry of framework, and formed error can be ignored, and wherein critical contact finger is crossed rope and the critical point that contacts of pulley;

In the measure portion of measurement mechanism,, be provided with the fixedly thick stick of some fixations at the offside of last measurement thick stick; Or, be provided with the fixedly thick stick of some fixations at the offside of measuring thick stick down.

Three thick stick type measuring method of tensile force refer to three bar single order type tension measurement method, or three bar difference type tension measurement method, or three bar difference type tension measurement method, or three-bar single support type tension measurement method, or three-bar multi-order single support type tension measurement method, or three-bar multi-support type tension measurement method, or one of the three-bar multi-order multi-support 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.
