Description

Detection tool for escalator

Technical Field

Background

With the demand of social development, the escalator is widely applied to public travel occasions such as markets, supermarkets, subways, airports and the like, and brings great convenience to public travel. Meanwhile, the frequent use of the escalator also increases the use risk and the potential safety hazard. In order to eliminate the potential safety hazard of use, the nation has special technical requirements on the design, production, installation, use, maintenance and scrapping of special equipment. At present, China promulgates a series of national standards and inspection rules, for example: standard requirements such as elevator manufacturing and installation safety regulations (GB7588-2003), escalator and moving sidewalk manufacturing and installation safety regulations (GB16899-2011), elevator supervision and inspection and periodic inspection rules (TSG T7001-2009), elevator supervision and inspection and periodic inspection rules (TSG T7005-2012) and the like. The technical requirements of elevator supervision and inspection and regular inspection rules for the escalator are as follows: the horizontal distance between the opening of the handrail belt and the handrail support is not more than 8 mm; the gap between the dado plates should be no more than 4 mm; the single side of the horizontal clearance between the step and the apron board is not more than 4mm, and the total clearance between the symmetrical sides is not more than 7 mm; the depth of engagement between the comb teeth of the comb plate and the tooth grooves of the tread surface is at least 4mm, and the clearance is not more than 4 mm. The lower surface of the rigid component of the apron plate anti-pinch device forms an inclination angle which is not less than 25 degrees upwards with the apron plate, the upper surface forms an inclination angle which is not less than 25 degrees downwards with the apron plate, and the rigid component and the flexible component of the anti-pinch device horizontally protrude.

Particularly, when the meshing depth and the gap between the comb teeth of the comb plate and the tooth grooves of the tread surface are measured, the measurement is very inconvenient because the matching gap between the comb teeth of the comb plate and the tooth grooves of the step tread surface is small and the installation position is low. The current measurement methods are as follows: firstly, measuring the depth of a tooth groove of a step tread surface by using a steel ruler, measuring the gap between comb teeth and the bottom of the tooth groove of the tread surface by using an inclined plug ruler, and subtracting to obtain the meshing depth; secondly, drawing a line which is flat with the tread surface on the comb teeth by a marking method, and detaching the comb teeth plate to measure the meshing depth; the gap between the root of the comb teeth and the top of the face teeth of the pedal is measured by a diagonal plug ruler.

The existing measuring method has the defects of complex process, inconvenient operation, low working efficiency, poor measuring precision and the like. At present, no special measuring tool exists, and a patent document (CN201710164626.X) proposes a multifunctional vernier for elevator inspection and measurement, and the main technical scheme is as follows: the novel vernier caliper comprises a main ruler and a vernier, wherein the main ruler comprises a rear jaw and a front baffle, the front baffle is connected to the upper side part of the front end of the main ruler, the rear jaw is connected to the rear end of the main ruler, a ruler body of the main ruler is clamped in a groove of the vernier and presses the ruler body of the main ruler through a scale clamp, a wide jaw at the rear end of the lower side of a vernier main body is matched with the rear jaw of the main ruler, and a screw is connected to the lower side of the vernier main body in a threaded manner. However, the disadvantages of the method are: aiming at the special arc structure of the end part of the comb teeth of the comb plate, the device can not scientifically measure the meshing data of the comb plate, and can not provide a method for directly measuring the meshing depth of the comb plate.

In addition, the rigid and flexible parts of the apron plate anti-pinch device are difficult to detect, such as: the included angle that rigid component upper and lower surface and apron board formed measures inconveniently, the level protrusion measurement of rigid and flexible part is inconvenient scheduling problem, and measurement to apron board anti-pinch device still does not have professional detection instrument at present.
