Referring to fig. 1 and 2, an elevator inspection tool includes a body 500, a first step groove 200, and a second step groove 300; the first stepped groove 200 and the second stepped groove 300 are respectively located at both sides of the body 500.

When the elevator inspection tool of the embodiment is applied, a cable to be detected can be clamped into a ladder with a corresponding width in the first ladder groove 200 or the second ladder groove 300, and whether the wire diameter of the cable is qualified or not can be judged according to the clamping degree of the cable and the ladder with the corresponding width without reading; wherein because two ladder grooves are located the both sides of body 500 respectively, effectively reduced the total length in every ladder groove when guaranteeing ladder quantity, effectively improved the easy problem of warping that sets up single ladder groove overlength and bring.

It should be noted that, the two stepped grooves are respectively disposed at two sides of the body 500, which means that the opening directions of the two stepped grooves are not disposed at the same side of the body, and the opening directions are different.

It is understood that the stepped groove referred to in this embodiment refers to a groove penetrating in the thickness direction of the body 500, one end of which is open outward in the extending direction of the groove, and at least one side wall surface of which in the extending direction of the groove has a step, so that the groove becomes a stepped groove having a plurality of different groove widths; wherein, the notch refers to a part ladder groove of every width, and two adjacent notches are the intercommunication, and a plurality of notches set gradually has constituted the ladder groove jointly.

Further, because the opening direction of two ladder grooves is opposite, when material saving, can guarantee that the length of body 500 is longer in the extending direction along two ladder grooves, when using body 500 to act as the ruler, can effectively increase the range of ruler.

As shown in fig. 1, in order to enable the body 500 to have the function of a ruler, scales can be engraved on one side of the body 500 to facilitate length measurement; of course, the scale can be attached to the body 500 by printing or pasting.

In order to facilitate the cable to be measured to be clamped into the stepped groove, the widths of the notches of the plurality of notches can be sequentially reduced from the opening of the first stepped groove 200 inwards; during measurement, cables with various wire diameters can be directly placed into the stepped groove from the opening of the stepped groove, and the stepped groove with the small width is prevented from blocking measurement of the cables with the large wire diameters.

As shown in fig. 2, in order to conveniently inspect three common cables of 6mm, 8mm and 10mm in the elevator, the first ladder groove 200 has three notches therein, and the notch widths H1, H2 and H3 of the three notches are respectively 9mm ± 0.05mm, 7.2mm ± 0.05mm and 5.4mm ± 0.05 mm; according to the relevant regulations of elevator detection regulations, the worn wire diameter of the cable to be detected is larger than 90% of the nominal wire diameter, so that the widths of the notches of the 3 notches are respectively set to be 9mm, 7.2mm and 5.4mm, machining errors of +/-0.05 mm are reserved, when the 10mm cable needs to be measured, the cable only needs to be clamped into the notches of 9mm +/-0.05 mm, if the cable can be clamped, the worn wire diameter is proved to be smaller than 90% of the nominal size, the cable can be judged to be unqualified at the moment, and reading is not needed; the method of measuring the cables for 6mm and 8mm is similar.

As shown in fig. 2, in order to enhance the function of the elevator detection device and simultaneously make full use of materials and increase the length of the body 500, one side of the first step groove 200 extends outwards to form a step plug portion; at this time, the step feeler gauge part not only can exert the function of the feeler gauge itself, but also can expand the length of the body 500, so that the usable range of the body 500 is larger when serving as a straight ruler.

In order to enable the stepped plug rule part to measure the widths of various gaps, the stepped plug rule part is provided with four steps, and the thicknesses t1, t2, t3 and t4 of the four steps are 4mm +/-0.01 mm, 6mm +/-0.01 mm, 8mm +/-0.01 mm and 10mm +/-0.01 mm from outside to inside in sequence; when the gap of 4mm needs to be measured, the step of 4mm can be plugged into the gap, and the gap can be judged to be too large through the matching condition of the step and the gap without reading; wherein, the plus or minus 0.01mm is the allowance range of the processing allowance, and the method for measuring the gaps with other widths is similar.

Further, the second stepped groove 300 may be provided to have a plurality of notches sequentially communicating, the notch widths of the plurality of notches being sequentially reduced inward from the opening of the second stepped groove 300, following the structure of the first stepped groove 200.

In order to further meet the measurement requirements of cables with different wire diameters, the notch widths H6, H5 and H4 of the notches in the second stepped slot 300 are respectively 14.4mm +/-0.05 mm, 11.7mm +/-0.05 mm and 10.8mm +/-0.05 mm; according to the relevant provisions according to the elevator detection regulations, the worn wire diameter of the cable to be detected is greater than 90% of the nominal wire diameter; therefore, when the 16mm cable is excessively worn to be measured, the 16mm cable is clamped into the 14.4mm +/-0.05 mm stepped groove, if the nominal 16mm cable can be clamped into the 14.4mm stepped groove, the abrasion of the cable can be judged to exceed 90%, and reading is not needed; while the method of measuring 12mm and 13mm cables is similar; wherein +/-0.05 mm is reserved for processing errors.

Note that outward in the present embodiment refers to a direction from inside the elevator inspection tool toward the opening of the first step groove 200 or the second step groove 300; the inward direction is opposite the outward direction.

In order to enable the elevator detection equipment to detect whether gaps beyond common widths are qualified or not, one side of the body 500 is provided with a wedge-shaped clearance gauge section 100; when gap width is measured to needs, can fill in the gap with the wedge feeler gauge, judge the size in feeler gauge gap through the butt position on gap lateral wall and wedge feeler gauge inclined plane, furtherly, can print the scale on the feeler gauge inclined plane, when the gap that needs measurement clearance be 4.5mm, only need fill in the gap with the wedge feeler gauge, if the size that leaks the gap on the feeler gauge surpasss the nominal size in clearance, can judge that the gap is too big.

In order to make elevator check out test set can conveniently measure elevator layer door lock depth of engagement, need not the reading, body 500 one side is provided with right angle breach 400, and right angle breach 400 is 7mm 0.05mm in the ascending width in two directions.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
