Description

Technical Field

[0001] This utility model relates to a new type of ruler for inspecting escalators, belonging to the technical field of escalator inspection tool design. Background Technology

[0002] Escalators in stations, shopping malls, and other similar locations typically require maintenance after two weeks of use, and annual inspections by third-party testing agencies are also necessary. Key checks during these inspections include: the skirt panels of escalators or moving walkways should be installed on both sides of the steps and treads, with gaps between the skirt panels and the steps / treads not exceeding 4mm; the gap between the comb teeth of the escalator's comb plate and the tooth grooves on the tread surface should not exceed 4mm, and the total gap at symmetrical locations on both sides should not exceed 7mm.

[0003] To facilitate testing, the applicant applied for a special ruler for escalator inspection on April 23, 2024 (application number 2024208464709). However, it was found that there was a certain error and the use was unstable. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of special ruler for inspecting escalators.

[0005] To achieve the aforementioned objectives, the present invention employs the following technical solution: A novel escalator inspection ruler, comprising a thickness gauge and a ruler body, wherein the thickness gauge is equipped with a measuring rod, the measuring rod moves on the thickness gauge, and the distance moved by the measuring rod is displayed on the thickness gauge; its characteristic is:

[0006] One end of the ruler is fixed to the thickness gauge, and the other end has a right-angled trapezoidal ruler on its side; the right-angled trapezoidal ruler is flush with the end of the ruler, and the side of the right-angled trapezoidal ruler facing the thickness gauge is an inclined surface;

[0007] The ruler body is provided with a measuring rod through hole and a moving rod hole. The length direction of the moving rod hole is parallel to the inclined plane of the right-angled trapezoidal ruler, and the moving rod hole passes through both sides of the width direction of the ruler body. One end of the measuring rod through hole is located at the end of the ruler body that is fixedly connected to the thickness gauge, and the other end is open and communicates with the moving rod hole.

[0008] It also includes a movable block; the movable block includes a movable rod and a movable seat, the movable seat is fixed to the bottom of the movable rod, the movable seat is parallel to the top of the right-angled trapezoidal ruler, and the movable rod is parallel to the inclined surface of the right-angled trapezoidal ruler; the movable rod passes through the movable rod hole and moves along the movable rod hole;

[0009] The side of the moving rod that contacts the measuring rod is provided with a triangular groove. The inner wall of one side of the triangular groove is parallel to the length direction of the measuring rod through hole, and the inner wall of one side contacts the measuring rod. When the moving seat is parallel to the top of the right-angled trapezoidal ruler, the measuring rod abuts against the inner wall of the triangular groove.

[0010] The movable base and movable rod move along the inclined plane of the right-angled trapezoidal ruler. Under the action of the triangular inclined groove, the measuring rod moves on the thickness gauge, and the thickness gauge displays the distance the measuring rod has moved.

[0011] The ruler body and the right-angled trapezoidal ruler are integrally formed.

[0012] One end of the measuring rod is mounted on the thickness gauge, and the other end is fixed with a ruler. The ruler contacts the inner wall of the triangular inclined groove. When the moving rod moves along the inclined surface of the right trapezoidal ruler, it drives the ruler to move under the action of the triangular inclined groove, which in turn pushes the measuring rod to move on the thickness gauge. The thickness gauge displays the distance the measuring rod has moved.

[0013] This utility model has a reasonable structure, and when used, it offers the following advantages:

[0014] 1. When measuring the gap between the skirt panel and the step, insert the right-angled trapezoidal ruler of the escalator inspection ruler into the gap between the skirt panel and the step. With the step blocking the movement, the moving seat pushes the moving rod into the moving rod hole as the right-angled trapezoidal ruler is inserted. Under the action of the triangular inclined groove on the moving rod, the measuring rod on the thickness gauge moves on the thickness gauge. Until the right-angled trapezoidal ruler can no longer be inserted, the measuring rod stops moving. The distance the measuring rod moves is displayed on the thickness gauge to obtain the gap between the skirt panel and the step, thus realizing the measurement of the gap distance between the skirt panel and the step.

[0015] 2. When measuring the gap between the comb teeth of the escalator's comb plate and the tooth grooves of the tread surface, insert the right-angled trapezoidal ruler of the escalator inspection ruler into the gap between the comb teeth and the tooth grooves of the tread surface. As the right-angled trapezoidal ruler is inserted, the moving seat pushes the moving rod to move into the moving rod hole. Under the action of the triangular inclined groove on the moving rod, the measuring rod on the thickness gauge is pushed to move on the thickness gauge until the right-angled trapezoidal ruler can no longer be inserted. The measuring rod stops moving, and the distance moved by the measuring rod is displayed by the thickness gauge. The gap between the comb teeth of the comb plate and the tooth grooves of the tread surface is obtained, thus realizing the measurement of the gap distance between the comb teeth of the comb plate and the tooth grooves of the tread surface.

[0016] This invention facilitates the measurement of gaps between apron boards and steps, and between comb teeth on comb plates and tread surfaces. During use, the movable base pushes the movable rod upwards at an angle, and the triangular groove within the movable rod simultaneously pushes the measuring rod on the thickness gauge upwards, allowing for the acquisition of corresponding measurement values. This structure exhibits small errors and stable measurements, thus possessing significant market application and promotion value. Attached Figure Description
