Elevator traction sheave and wire rope mainly transmit power to rub, and elevator normally runs and must meet certain traction condition, and the too little meeting of hauling capacity causes wire rope slippage on the traction sheave.As shown in Figure 1 and Figure 2, the cross section of the traction race 71 of traction sheave 7 is bottom truncated cone-shaped 72 and the arc expansion portion 73 that to be positioned at bottom truncated cone-shaped on 72.Traction steel-cable is general only to be contacted with arc expansion portion, and after traction steel-cable stand under load, the arc expansion portion of traction race produces juxtaposition metamorphose, and this juxtaposition metamorphose can affect equlvalent coefficient of friction, thus affects hauling capacity.And after the arc expansion portion wearing and tearing of traction race, its size shape will change, thus affect equlvalent coefficient of friction, cause hauling capacity to decline.Therefore the geometrical variations of elevator traction sheave is measured to elevator traction sheave failure detection important in inhibiting.
On March 18th, 2015, application number be 201310377325.7 innovation and creation disclose a kind of aperture measurement device, comprise cylindrical shell, the circumferential wall of cylindrical shell is arranged with a pair radial hole, be slidably matched in each radial hole a contact, one end of contact extend in the axial hole of cylindrical shell, the other end of contact passes from the aperture of the radial hole be positioned at cylindrical shell circumference wall, the end that contact extend into the axial hole of cylindrical shell is provided with inclined-plane, on contact, cover has the spring of taper, one end of spring is connected with contact, the other end and the cylindrical shell of spring are fixed, a sleeve is provided with in the axial hole of cylindrical shell, be connected with a dial gauge after one end of this sleeve reaches the axial hole outside of cylindrical shell, the measuring staff of dial gauge extend in sleeve, the end of this measuring staff is conically.The program can converse aperture value by the reading of dial gauge.
Clock gauge converts general straight-line displacement the rotary motion of pointer to by gear or lever, on index dial, then carry out the length measuring instrument of reading.Clock gauge has the types such as dial plate clock gauge, Electronic Digital Micrometer.
In prior art, that measures internal diameter device has micrometer inside caliper etc.The internal measuring instrument that Germany DIATEST produces has internal diameter measuring instrument, bore measuring instrument, electronic digital display feeler gauge, two flap-type measuring instruments, micrometer inside caliper etc.Its two flap-type measuring instrument obtains aperture value by the change of horizontal range between two lobes, and this two flap-type measuring instrument is furnished with the gauge head of various model, for the hole slot of difformity and size, can change different gauge heads.
Current use plug gauge type measuring system measures traction sheave well width, when artificial hand-held plug gauge type measuring system is measured, cannot ensure that the measuring head central cross-section of measurement feeler gauge and traction sheave groove center cross section coincide, cannot obtain the measurement data that precision is higher.In addition, plug gauge type measuring system can not measure the degree of depth at the frayed place of traction race.
The measuring head of prior art mesoporous measuring instrument is generally three-clove style to feel relieved, and this programme only need obtain the numerical value of width, has used for reference the two flap-type measuring instruments that German DIATEST produces.
As further technical scheme, described support is provided with 2 Bidirectional-screws, 2 Bidirectional-screws lay respectively at the both sides of bidirectional measurement instrument, and each Bidirectional-screw is provided with 2 movable blocks oppositely simultaneously moved, the bottom of movable block is all fixed with can deeply to the intermediate plate in traction race.
Present solution provides a kind of bidirectional measurement instrument locator meams of optimization, by intermediate plate, bidirectional measurement instrument is stretched in traction race.By the rotation of Bidirectional-screw, neatly bidirectional measurement instrument can be positioned any position in ring-type traction race.
As further technical scheme, 2 that described each Bidirectional-screw the is arranged movable blocks oppositely simultaneously moved are symmetrical about a vertical plane all the time, and the axis of sounding rod is positioned on this vertical plane.
The program has the effect of centering, ensures that the axis of sounding rod is positioned at the centre of traction race all the time, improves the precision measured.
As further technical scheme, the end of described Bidirectional-screw is provided with Handheld Division.Handheld Division is convenient for measuring human users.
As further technical scheme, described support is provided with the latch mechanism for locking bidirectional measurement instrument.Bidirectional measurement instrument has certain deadweight, only fixing with manually hold during measurement, and data easily start fluctuation, and bidirectional measurement instrument to be lock onto on support reading again by latch mechanism, and data can not fluctuate.
In sum, the utility model has modern design, Stability Analysis of Structures, advantage easy to use, can measure the width of each traction race under different depth quickly and accurately, improve stability and the accuracy of measurement.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of plug gauge type measurement mechanism for elevator traction sheave is provided, to measure the width of each traction race under different depth quickly and accurately, thus judge the position at the frayed place of traction race and frayed degree fast.
To achieve these goals, the technical solution of the utility model is as follows: a kind of plug gauge type measurement mechanism for elevator traction sheave, comprise the support that can be fixed on single traction race, support is provided with bidirectional measurement instrument, bidirectional measurement instrument has the display of sounding rod and display measurement result, the bottom of sounding rod is width measure head, measures while bidirectional measurement instrument vertically can move up and down and realize the degree of depth and width.
Clock gauge and internal diameter measuring instrument merge by this programme, those skilled in the art easily obtain this bidirectional measurement instrument, width measure head is set bottom the sounding rod of clock gauge, by the mode of electronic digital display, the width that the degree of depth at width measure head place and width measure head record is simultaneously displayed on display.Bidirectional measurement instrument is positioned on the traction race of ground traction sheave by support, can accurately measure the width of each traction race under different depth.
