Abstract
The utility model provides a new fully-machinery direct-reading steel wire stretch-draw force testing instrument. The utility model is suitable for testing stretch-draw force value of compressor steel wire which are produced on a long line pedestal. The measurand steel wire does not need rust removing and soil release processing before the steel wire is measured, and the stretch-draw force value of the steel wire can be displayed visually without conversion. The utility model is composed of a main transmission system, a regulating system, an indication mechanism, etc. The fully-machinery direct-reading steel wire stretch-draw force testing instrument has the advantages of compact complete instrument, simple operation, damp-proof, dust-proof and corrosion-proof. The price of the new fully-machinery direct-reading steel wire stretch-draw force testing instrument is 20-30 percents of the price of electrical force testing instrument, and testing accuracy is consistent with the requirement of current national regulation.
Description
The utility model is the detecting instrument of wire tensioning force during a kind of construction work prestress is produced.
In the mensuration to the steel wire stretching value, using more method is flexibility method (static(al) method) and method of oscillatory frequency (vibratory drilling method) at present, the instrument that in said method, uses, and a class is a mechanical type, another kind of is electronic type.Domestic prior mechanical dynamometer, generally when measuring initial reading, being that pilot lamp is bright when relying on contact contact with steel wire is as the criterion, if Steel Wire Surface has greasy dirt, or contact advances above starting point during test, all can cause initial reading to be forbidden, and causes personal error.Electronic type dynamometer volume is bigger, and price is higher, and use simultaneously is easily affected by environment, and the factory for prefabrication generally is the detection of carrying out wire tensioning force in the open, and environmental baseline is abominable, and instrument is out of order.More than two kinds of instruments also bigger to the error that the steel wire diameter deviation causes.
The utility model proposes a kind of new wire tensioning force detector, this instruments design becomes fully mechanical, and tested reinforcing bar does not need the decontamination that eliminates rust before survey, and the steel wire stretching value intuitively shows on instrument, need not convert direct-reading rapidly.This detector is made up of main transmission, Adjustment System and indication mechanism and housing etc.Be described in detail as follows in conjunction with the accompanying drawings:
Accompanying drawing 1 is the synoptic diagram of embodiment 1: an oblate contact (1) is established on the top of instrument, the midline of contact upper surface has a groove, and center system one little axle in lower surface inserts in the hole of screw rod (15), the axle head riveting is opened, so as to the axial displacement of fixed contact (1).Screw rod (15) cooperates with top stem casing (14), top stem casing (14) is cylindrical, the upper end is shaped on internal thread, the lower end cooperates with guide pin bushing (4) head, lower surface and guide pin bushing (4) shoulder offsets, the inside of guide pin bushing is hollow, head is held and is adjusted screw (3), the made nut in the screw rod of adjusting screw and gland (13) top cooperates, gland (13) center is shaped on circular hole, the screw rod of adjusting screw (3) is passed through, and gland (13) is divided into spring (6), and spring (6) places on the spring base (7).The lower end of the nearly guide pin bushing (4) of housing (5) is provided with several balls (9) along inner periphery, and any of each ball (9) pearl face touched mutually with the cylindrical of guide pin bushing (4) lower end.One side of housing (5) has a hollow elongated slot, groove face is provided with the reflection shield (10) of a rear reflector (11) and an angle adjustable, establish indicator slide block (12) in the groove, indicator slide block is fixed on guide pin bushing (4) periphery, housing (5) upper surface is provided with a mark post (2), and the center, lower surface has one notch (8).
The utility model can be simple and direct and be detected exactly the stretch-draw value of steel wire, and measuring accuracy meets existing national regulation requirement, for the quality of raising prestressed component has positive meaning. This detector volume is little, in light weight, easy and simple to handle, survey is read rapidly, moistureproof, dustproof, corrosion-resistant, price is about 20%～30% of electronic type dynamometer, from improving quality, reduce national loss and reduce the equipment investment each side, all will obtain huge benefit.
The detection of the compressor wire stretch-draw value that the utility model is particularly useful for producing on the long-line pedestal.
