Description

Technical Field

[0001] This utility model relates to the field of escalator skirt panel gap detection, specifically a dynamic gap detection device for escalator skirt panels. Background Technology

[0002] Escalator skirts are fixed panels on both sides of an escalator, used to conceal the internal structure and ensure passenger safety. The function of the escalator skirts is to prevent passengers' bodies or belongings from being caught in the escalator while riding. The skirts are typically made of metal or other sturdy materials, and anti-pinch devices, such as brushes or rubber strips, are installed at the gap between them and the steps to further enhance safety. To ensure the installation safety of the escalator skirts, their dynamic gap needs to be detected, requiring the use of a detection device. The "A Gap Detection Device Between Escalator Steps and Skirts" disclosed in application number "202322981620.5" represents an increasingly mature technology. This escalator gap detection device can detect gaps in automatic escalators... "When the upper end of the escalator is a discontinuous surface, continuous dynamic vertical distance measurement is performed, which reduces the complexity of the measurement process, saves time, and increases accuracy." However, this detection device still has the following drawbacks during use: While the device, with its sliding table and hydraulic cylinder, can indeed facilitate gap detection on one side of the escalator skirt panel, it can only detect a single escalator skirt panel, thus affecting detection efficiency. Therefore, it is necessary to provide a monitoring device that can simultaneously detect the skirt panels of both escalators, thereby improving detection efficiency. In addition, the integral structure of this detection device makes it inconvenient to disassemble and replace the components as needed. Therefore, it is necessary to provide a detection device that facilitates the disassembly and replacement of the components. Utility Model Content

[0003] This utility model provides a dynamic gap detection device for escalator skirt panels, aiming to solve the problem that existing detection devices are inconvenient for simultaneously detecting the gap between escalator skirt panels on both sides.

[0004] To achieve the above objectives, this utility model provides a dynamic gap detection device for escalator skirt panels, including detection components;

[0005] The detection component includes a push-pull block, both ends of which are detachably mounted with mounting plates. A lead screw and a guide rod are rotatably connected inside the push-pull block. Each of the two mounting plates has a first screw hole and a guide hole on its opposite surface. The lead screw is threaded into the first screw hole, and the guide rod is inserted into the guide hole. Several mating grooves are provided at the lower ends of both the push-pull block and the mounting plates. A laser rangefinder is mounted at the ends of both mounting plates. Hydraulic cylinders are detachably mounted at the upper ends of both mounting plates. A detection block is detachably mounted at the output end of the hydraulic cylinder, and a scale line is provided at the lower end of the detection block.

[0006] As a preferred embodiment of this utility model, a concave block is fixedly installed on the upper end of the mounting plate, a limiting hole is opened inside the concave block, a limiting shaft is installed at one end of the hydraulic cylinder, and the limiting shaft is inserted into the limiting hole.

[0007] As a preferred embodiment of this utility model, a positioning strip is fixedly installed on the upper end of the mounting plate, the positioning strip is snapped into the bottom of the hydraulic cylinder, and a handle is fixedly connected to the upper end of the push-pull block.

[0008] As a preferred embodiment of this utility model, the upper end of the mounting plate has two strip grooves, and two slide bars are fixedly connected to both sides of the detection block, with both slide bars slidably connected inside the strip grooves.

[0009] As a preferred embodiment of this utility model, the upper end of the mounting plate is provided with a guide groove, and the lower end of the detection block is fixedly connected with a guide block, which is slidably connected inside the guide groove.

[0010] As a preferred embodiment of this utility model, one end of the detection block is provided with a second screw hole, and the output end of the hydraulic cylinder is fixedly connected with a second bolt, which is threaded into the inside of the second screw hole.

[0011] In a preferred embodiment of this utility model, both the mounting plate and the detection block are made of cast aluminum.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When simultaneously inspecting the skirt panels of both escalators, first adjust the distance between the two mounting plates according to the size of the escalator steps so that the ends of the two mounting plates are engaged and aligned with the top of the steps. Then, the groove at the top of the steps and the matching groove are engaged. At this time, control the output ends of the two hydraulic cylinders to move the detection block. The detection block supports the surface of the escalator skirt panel. The difference between the detection block and the mounting plate can be measured by the scale line to perform the initial inspection. At the same time, the laser rangefinder can facilitate further inspection of the gap between the mounting plate and the detection block. Compared with the detection device in the existing technology "A device for detecting the gap between an escalator step and a skirt panel", this utility model can facilitate dual inspection of the gap of the escalator skirt panel through the cooperation of the above structures, thereby improving the inspection efficiency of the detection device.

[0014] 2. When disassembling the detection device, first remove the limiting shaft from the limiting hole to disassemble the hydraulic cylinder. Then remove the lead screw from the first screw hole to disassemble the mounting plate and push-pull block. Finally, remove the second bolt from the second screw hole to disassemble the detection block. Compared with the detection device in the prior art "A detection device for the gap between an escalator step and apron", this utility model, through the cooperation of the above structures, facilitates the disassembly of each component of the detection device and improves the convenience of disassembly and replacement of each component.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-4 This utility model provides a dynamic gap detection device for escalator skirt panels, including a detection component 100;

[0023] The detection component 100 includes a push-pull block 101. Both ends of the push-pull block 101 are detachably mounted with mounting plates 102. A lead screw 103 and a guide rod 104 are rotatably connected inside the push-pull block 101. The opposing surfaces of the two mounting plates 102 are respectively provided with a first screw hole 105 and a guide hole 106. The lead screw 103 is threaded into the first screw hole 105, and the guide rod 104 is inserted into the guide hole 106. The lower ends of both the push-pull block 101 and the mounting plates 102 are provided with several mating grooves 107. Laser rangefinders 108 are mounted at the ends of both mounting plates 102. Hydraulic cylinders 109 are detachably mounted on the upper ends of both mounting plates 102. A detection block 110 is detachably mounted on the output end of the hydraulic cylinder 109. A scale line 120 is provided at the lower end of the detection block 110.

[0024] In one specific embodiment, the detection component 100 not only enables dynamic gap detection of the escalator skirt panels on both sides of the volume simultaneously, thereby improving the detection efficiency of the detection device, but also facilitates gap detection of escalator skirt panels of different widths, enhancing the versatility of the detection device. Furthermore, the coordinated structure facilitates the disassembly and assembly of each component, improving the ease of replacement. When detecting escalator skirt panels of different widths, the lead screw 103 is first controlled to rotate clockwise or counterclockwise as needed, thereby adjusting the distance between the two mounting plates 102 to match different escalator step sizes. Then, by simultaneously activating the two hydraulic cylinders 109, the end of the detection block 110 is controlled to support the escalator skirt panel. At this point, the difference between the mounting plate 102 and the detection block 110 is measured using the scale line 120 to perform a preliminary detection of the escalator skirt panel gap. Simultaneously, the laser rangefinder 108 enables further detection, thereby improving the versatility and detection efficiency of the detection device.

[0025] Please see Figures 2-4A concave block 111 is fixedly installed on the upper end of the mounting plate 102. A limit hole 112 is opened inside the concave block 111. A limit shaft 113 is installed on one end of the hydraulic cylinder 109. The limit shaft 113 is inserted into the limit hole 112.

[0026] In one specific embodiment, the limiting shaft 113 is inserted into the limiting hole 112, and together with the concave block 111, it can initially improve the installation stability between the hydraulic cylinder 109 and the mounting plate 102.

[0027] Please see Figures 2-4 A positioning strip 121 is fixedly installed on the upper end of the mounting plate 102. The positioning strip 121 is snapped into the bottom of the hydraulic cylinder 109. A handle 122 is fixedly connected to the upper end of the push-pull block 101.

[0028] In one specific embodiment, the positioning strip 121 is snapped into the inside of the hydraulic cylinder 109, which can further improve the connection stability between the hydraulic cylinder 109 and the mounting plate 102.

[0029] Please see Figures 2-4 The upper end of the mounting plate 102 has two strip grooves 131. Two sliders 132 are fixedly connected to both sides of the detection block 110. Both sliders 132 are slidably connected inside the strip grooves 131.

[0030] In one specific embodiment, when the detection block 110 moves, the slide bar 132 moves along the strip groove 131, thereby improving the movement stability of the detection block 110 and ensuring the accuracy of the escalator skirt board gap detection.

[0031] Please see Figures 2-4 The upper end of the mounting plate 102 is provided with a guide groove 141, and the lower end of the detection block 110 is fixedly connected with a guide block 142, which is slidably connected inside the guide groove 141.

[0032] In one specific embodiment, the movement of the guide block 142 along the guide groove 141 can limit the movement of the detection block 110, thereby enhancing the stability of the movement of the detection block 110.

[0033] Please see Figures 2-4 The detection block 110 has a second screw hole 151 at one end, and the output end of the hydraulic cylinder 109 is fixedly connected to a second bolt 152, which is threaded into the inside of the second screw hole 151.

[0034] In one specific embodiment, the second bolt 152 is threaded into the second bolt hole 151, which can improve the ease of disassembly and replacement between the hydraulic cylinder 109 and the detection block 110.

[0035] Please see Figures 2-4The mounting plate 102 and the detection block 110 are both made of cast aluminum.

[0036] In one specific embodiment, the mounting plate 102 and the detection block 110, made of cast aluminum, can reduce their weight and improve the portability and ease of use of the detection device.

[0037] Working principle: When inspecting the skirt panels of escalators of different widths, the distance between the two mounting plates 102 can be adjusted by controlling the screw 103 to rotate clockwise or counterclockwise as needed, so as to match the escalator steps of different sizes. Then, the two hydraulic cylinders 109 are activated simultaneously to push, thereby controlling the end of the detection block 110 to support the escalator skirt panel. At this time, the difference between the mounting plate 102 and the detection block 110 is measured by the scale line 120, which can be used to perform a preliminary inspection of the gap of the escalator skirt panel. At the same time, the laser rangefinder 108 can be used for further inspection, thus improving the versatility and inspection efficiency of the inspection device.
