Description

Technical Field

[0001] The utility model relates to a gap detection device, in particular to a gap detection device between steps and apron plates of an escalator. Background Art

[0002] As a mechanical device, the carrying characteristics of escalators indicate that contact between the objects they serve and moving parts is unavoidable. Therefore, designers cannot completely eliminate the risks of escalators through intrinsically safe design. The safety risks of escalators are mainly concentrated in shearing, squeezing, falling, and collision, and the defects that cause safety risks are mainly concentrated in the gaps between moving parts and the safe distance between escalators and buildings. In the actual working process, some gaps or safe distances are closely related to the state of motion, and the static measurement data are quite different from the actual situation.

[0003] According to TSGT7005-2012 "Rules for Elevator Supervision Inspection and Periodic Inspection - Escalators and Moving Walkways", there are requirements for the gap between the steps (or pedals) and the apron plate and the vertical clear height above the steps (or pedals): First, the vertical clear height above the steps of the escalator or the pedals or tape of the moving walkway shall be no less than 2.30m, and the clear height shall extend to the turning end of the handrail; second, the apron plates of the escalator or moving walkway are set on both sides of the steps, and the horizontal gap on any side shall not be greater than 4mm, and the sum of the gaps at the symmetrical positions on both sides shall not be greater than 7mm.

[0004] In the actual inspection process, both of these requirements have measurement difficulties: First, in the vertical clear height inspection, if there is a beam above the steps, the relative position of the steps and the beam must be continuously moved to measure the relatively small value of the vertical clear height. The measurement process is cumbersome, time-consuming, and the data has certain errors. Second, in the inspection of the gap between the steps, pedals, or tapes and the apron board, only static measurement can be adopted, that is, measurement in the stopped state of the elevator. In fact, there is the possibility of serpentine motion during the operation of the escalator. At this time, the value of the gap in the running state is quite different from the value in the static state. There is currently no better way to detect the gap during the motion process.

[0005] Chinese patent 202221471615.9 discloses an escalator step and apron plate gap detection device, which has the function of improving the measurement accuracy by placing the device vertically relative to the two apron plates. However, the device requires manual adjustment of the distance between the movable seat and the detection device body, which is somewhat cumbersome, and the detection process is mostly static measurement, which fails to fully realize the measurement of the gap between the step and the apron plate when the escalator is in motion. In addition, the device cannot dynamically detect the vertical clear height above the step. At present, there is no utility model design for an escalator apron plate and step gap detection device with high automation, less time consumption, high precision, strong dynamic gap detection capability, simple structure, and the ability to simultaneously detect the vertical clear height inspection and the gap between the step, pedal or tape and the apron plate.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the specific structure and connection relationship of the escalator step and apron plate gap detection device described in the utility model are as follows:

[0024] The first sliding mechanism 20 is composed of a slide bracket 1, a motor 2, a lead screw 3, a slider guide 14, a slider guide 25, a slider guide 5 16, a slider 19, a base bracket 16, and a base bracket 2 15; the base bracket 2 15 and the base bracket 6 are installed and fixed on the slide bracket 1, the slider guide 14 and the slider guide 25 are installed and fixed on the slide bracket 1, the slider guide 5 16 is installed and fixed on the slide bracket 1, the lead screw 3 is connected to the slide bracket 1 through a rotating pair, the slider 19 is connected to the slider guide 14 through a moving pair, the slider 19 is connected to the slider guide 25 through a moving pair, the slider 19 is connected to the slider guide 5 16 through a moving pair, and the slider 19 is connected to the lead screw 3 through a spiral pair.

[0025] The second sliding mechanism 20 is composed of a slide bracket 2 8, a motor 2 7, a lead screw 2, a slider guide 3 9, a slider guide 4 11, a slider guide 6 17, a slider 2 18, a measuring probe 1 12, a measuring probe 2 13, and a measuring probe 3 14; the slider guide 3 9 and the slider guide 4 11 are installed and fixed on the slide bracket 2 8, the slider guide 6 17 is installed and fixed on the slide bracket 2 8, the lead screw 2 is connected to the slide bracket 2 8 through a rotating pair, the slider 2 18 is connected to the slider guide 3 9 through a moving pair, the slider 2 18 is connected to the slider guide 4 11 through a moving pair, the slider 2 18 is connected to the slider guide 6 17 through a moving pair, and the slider 2 18 is connected to the lead screw 2 through a spiral pair.

[0026] The first sliding mechanism 20 is fixed on the slider 2 18 by bolt connection, and remains perpendicular to the first sliding mechanism 20. The measuring probe 1 12 is connected to the slider 2 18 and fixed on the slider 2 18, the measuring probe 2 13 is connected to the slider 2 18 and fixed on the slider 2 18, and the measuring probe 3 14 is connected to the slider 2 18 and fixed on the slider 2 18.

[0027] The working principle of the utility model is as follows: taking the first sliding mechanism 20 as an example, the first sliding mechanism 20 is composed of a slide bracket 1, a motor 2, a lead screw 3, a slider guide 14, a slider guide 25, a slider guide 5 16, a slider 19, a base bracket 16, and a base bracket 2 15; the base bracket 2 15 and the base bracket 6 are installed and fixed on the slide bracket 1, the slider guide 14 and the slider guide 25 are installed and fixed on the slide bracket 1, the slider guide 5 16 is installed and fixed on the slide bracket 1, the lead screw 3 is connected to the slide bracket 1 through a rotating pair, the slider 19 is connected to the slider guide 14 through a moving pair, the slider 19 is connected to the slider guide 25 through a moving pair, the slider 19 is connected to the slider guide 5 16 through a moving pair, and the slider 19 is connected to the lead screw 3 through a spiral pair. The slider 19 is connected to the lead screw 3 through a lead screw pair, so the rotation of the lead screw 3 can drive the slider to slide at the same time, and the slider 19 can slide on the slider guide rail 14, the slider guide rail 25, and the slider guide rail 5 16. At the same time, the slider guide rail 14 and the slider guide rail 25 have a certain rotation protection function to prevent people from accidentally touching the rotating lead screw 3. The motor 2 can drive the lead screw 3 to rotate, and the lead screw 3 can drive the slider 19 to move horizontally by rotating.

[0029] , measuring probe 2 13 and measuring probe 3 14 are fixedly mounted on slider 2 18 , so slider 2 18 has two degrees of freedom of movement on the step horizontal plane.

[0030] like Figure 5 As shown, at the beginning of the measurement, the gap detection device is first placed on the step, and the gap detection device is fixed on the step through the base 1 and the base 2. When measuring the vertical clear height, the escalator can be operated first, and the slider 2 18 can move left and right along the horizontal direction of the step surface parallel to the step edge and move forward and backward along the step surface direction perpendicular to the step edge at the same time. The measuring probe 2 13 can measure the vertical clear height value above the step, and the unqualified position can be found through data processing. Taking the escalator as an example, in the inspection of the gap between the step and the apron plate, the measuring probe 1 12 and the measuring probe 3 14 can respectively measure the distance between the left apron plate, the left step and the right apron plate, and the right step, and then the gap between the step and the apron plate can be obtained by subtracting the distance between the left apron plate, the left step and the right apron plate, and the right step, and the unqualified position can be found through data processing, and dynamic measurement can be achieved, providing convenient and reliable measurement data for the inspection of the escalator.
