Detailed Description
The structure and principle of such a device will be apparent to those skilled in the art from the following further description of the invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
This embodiment provides an automatic staircase step levelness on-line measuring device, refer to fig. 1 and fig. 2, show prior art's general handrail elevator and stair structure, its step includes the footboard and is used for connecting the installation department of main round and auxiliary wheel, as shown in fig. 3, this embodiment outwards symmetry is equipped with left extension section and right extension section in the left and right sides of step rear end, the opposite side of left extension section and right extension section is equipped with the reflector layer, the reflector layer can be obtained through bolted connection or welding or paste photoelectric switch with the reflector panel through glue, or obtain through scribbling the reflection of light picture layer, the left and right sides of step front end be equipped with respectively and be used for the left part recess that matches with left extension section and the right part recess that matches with right extension section. For the existing escalator structure, a horizontal stair section is respectively arranged at the starting end and the terminal end of the escalator, and front and rear adjacent stairs are required to be positioned on the same horizontal plane in the horizontal stair section. By the design of the present embodiment, as shown in fig. 4, when the steps are located in the horizontal step section, the left extension section of the previous step can be matched with the left groove of the next step, and the right extension section of the previous step can be matched with the right groove of the next step, so as to ensure that the adjacent steps can be matched and connected in the horizontal step section and located on the same horizontal plane.
The opposite side of the apron board on the left side and the right side of the escalator, namely the side of the apron board close to the step, is respectively provided with a plurality of mirror reflection type photoelectric switches along the running track of the step, each reflection type photoelectric switch is a photoelectric switch integrating a transmitter and a receiver, and light emitted by each reflection type photoelectric switch can be reflected back to the receiver after passing through a reflector so as to generate a reflection signal. The mirror reflection type photoelectric switch mirror is fixed on the inner side of the apron board through known connection modes such as bolt connection or welding, the position of the mirror reflection type photoelectric switch mirror is slightly higher than the upper surface of the step in normal operation, when the step is in normal operation, the left side and the right side of the same step are positioned on the same horizontal plane, as shown in fig. 5, at the moment, the mirror reflection type photoelectric switch cannot irradiate a reflective layer, and therefore a reflection signal cannot be received; when the step collapses and inclines to a certain side, as shown in fig. 6, because passengers often stand on the right side of the elevator, the main wheel and the auxiliary wheel on the right side of the step are subjected to more stress, and when the step inclines to the right side due to abrasion, the ray emitted by the mirror reflection type photoelectric switch arranged on the apron board on the left side of the step is reflected by the reflecting layer of the right extending section, so that the mirror reflection type photoelectric switch receives the reflected signal.
Therefore, through the arrangement of the embodiment, the levelness of the step can be monitored on line without stopping the operation of the elevator, and if the step inclines in the left and right directions in the operation process of the elevator, a corresponding signal can be timely measured through the mirror reflection type photoelectric switch, so that the manual detection is not required frequently, and the stable operation of the elevator is ensured.
Further, there is a possibility that the elevator steps may be inclined in the front-rear direction, which is less likely to occur, and the inclination of the steps is generally caused by uneven forces applied to the left and right sides, but in order to prevent a safety risk caused by the front-rear inclination of the steps, in the present embodiment, a front-rear direction groove is further provided in the middle of the steps of the elevator, the front-rear direction being a traveling direction of the elevator steps, and a level gauge is provided in the groove to detect the inclination in the front-rear direction of the steps. As shown in fig. 7, 8 and 9, stepped structures are further arranged at the front end and the rear end of the groove, and bolt holes are formed in the stepped structures and are used for being connected with the upper cover of the groove in a matched mode through bolts so as to facilitate positioning, mounting and dismounting of the upper cover of the groove. The spirit levels are various, such as laser spirit levels, bubble spirit levels and the like, the bubble spirit levels are adopted in the embodiment, the principle of the bubble spirit levels is that bubbles are arranged in a glass tube, the bubbles can be always kept at the highest positions, when the steps are inclined in the front-back direction, the bubbles can move in the front-back direction, so that the inclination of the steps can be known, at the moment, the upper cover of the groove needs to be made of transparent materials, such as transparent glass or plastics, only a maintainer needs to regularly observe the spirit levels to know whether the steps are inclined in the front-back direction, the maintainer does not need to have specific detection skills and experience, and the convenience in detecting the levelness of the elevator steps is greatly improved.
