[0002] An escalator is composed of a chain conveyor with a special structure form and two belt conveyors with special structure forms, with a circulating moving ladder road, and is a fixed electric drive device used to transport passengers upward or downward between different floors of a building at an inclined angle, and can also be used to carry people.

[0003] The patent specification with the publication number of CN212151289U discloses an automatic escalator operation and fault monitoring device, including an escalator and a second horn. Handrails are arranged around the escalator, and steps are arranged at the lower end of the escalator. A motor is arranged in the middle of the steps, and a transmission shaft is arranged on one side of the motor. A transmission gear is arranged in the middle of the transmission shaft, and a belt is attached to the outer wall of the transmission gear. A detection box is arranged on the other side of the transmission shaft, and fixing blocks are arranged on both sides in the middle of the detection box. A handrail driver is arranged above the motor. This escalator operation and fault monitoring device has a rotational speed detector, which is symmetrically distributed along the vertical central axis of the detection box. The rotational speed detector is arranged in the detection box. By fixing the position of the rotational speed detector of the fixing block, the displacement during the detection of the rotational speed of the transmission shaft can be prevented, which affects the detection effect. When the rotational speed of the transmission shaft is too fast or too slow, the rotational speed detector can give a prompt through the first horn.

[0004] However, in the implementation of related technologies, it is found that the above-designed automatic escalator operation and fault monitoring device has the following problems: In the prior art, the operation of the escalator is monitored through a rotational speed detector, but heat is easily generated during the monitoring process. If it is not discharged for a long time, it will affect some components and reduce the service life of the device. In view of this, a high-reliability automatic escalator operation and fault monitoring device is provided to overcome the above defects. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and a high-reliability automatic escalator operation and fault monitoring device is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A high-reliability automatic escalator operation and fault monitoring device, including an installation shell, a clamping plate is fixed inside the installation shell, and an acquisition and processing module is arranged inside the clamping plate. A refrigeration shell is fixed below the installation shell, and a heat dissipation mechanism is arranged inside the refrigeration shell;

[0007] The heat dissipation mechanism includes a mounting frame which is fixed on one side of the outer wall of the refrigeration shell. A refrigeration sheet is embedded at the bottom end inside the refrigeration shell. A motor is embedded on the outer wall of the mounting frame, and a worm is connected to the power output end of the motor. The worm penetrates into one side of the outer wall of the refrigeration shell and is connected to a worm gear. A rotating shaft passes through the inside of the worm gear. A fan blade is fixed on the outer wall of the end of the rotating shaft that penetrates into the installation shell. The acquisition and processing module is clamped and placed through a clamping plate. The acquisition and processing module has three parts: a high-speed data acquisition device, a controller, and a timer. The high-speed data acquisition device composed of current and voltage sensors and the like is used to acquire digital quantity signals such as the action of the safety circuit of the escalator, the action of the brake, the opening of the maintenance panel, and the running instruction direction of the escalator, and then processed by the controller, and combined with the timer to identify the running state of the escalator.

The temperature inside the refrigeration shell is reduced by the refrigeration sheet, and the cold air enters the installation shell for heat dissipation to avoid overheating.

[0009] As a further description of the above technical solution: Filter nets are embedded on both sides of the outer wall of the refrigeration shell. A scraper is fixed at the position where the outer wall of the worm is in contact with the filter net. The filter net facilitates filtering the flowing gas, filtering out dust and impurities to prevent them from entering and affecting the internal components. At the same time, a filter net is embedded in the reserved hole opened at the top of the installation shell to facilitate the outflow of air while preventing dust from entering.

After the cover plate and the installation shell are closed, the acquisition and processing module is limited by the pressing block to avoid excessive shaking.

[0011] As a further description of the above technical solution: A stabilizing mechanism is arranged below the acquisition and processing module. The stabilizing mechanism includes a first damping spring which is fixed at the bottom end of the clamping plate, and one end of the first damping spring is connected to a pressing plate.

[0024] Refer to Figures 1-5 As shown in the figure, the utility model provides a highly reliable escalator operation and fault monitoring device, which includes an installation shell 1. A clamping plate 2 is fixed inside the installation shell 1, an acquisition and processing module 3 is arranged inside the clamping plate 2, a refrigeration shell 4 is fixed below the installation shell 1, and a heat dissipation mechanism 5 is arranged inside the refrigeration shell 4;

[0025] The heat dissipation mechanism 5 includes an installation frame 501. The installation frame 501 is fixed on one side of the outer wall of the refrigeration shell 4. A refrigeration sheet 503 is embedded at the bottom end inside the refrigeration shell 4. A motor 502 is embedded on the outer wall of the installation frame 501. The power output end of the motor 502 is connected to a worm 504. The worm 504 penetrates through one side of the outer wall of the refrigeration shell 4 and is connected to a worm gear 505. A rotating shaft 506 penetrates out of the inside of the worm gear 505. A fan blade 507 is fixed on the outer wall of one end of the rotating shaft 506 that penetrates into the installation shell 1. The acquisition and processing module 3 is clamped and arranged through the clamping plate 2. The acquisition and processing module 3 has three parts: a high-speed data collector, a controller, and a timer. The high-speed data collector composed of current and voltage sensors and the like is used to collect switch quantity signals such as the action of the escalator safety circuit, the action of the brake, the opening of the maintenance board, and the running instruction direction of the escalator, and then is processed by the controller, and the running state of the escalator is identified in combination with the timer.

[0026] As a further implementation of the above technical solution: The installation shell 1 is communicated with the refrigeration shell 4. The installation shell 1 is detachably connected to the clamping plate 2 through bolts. The temperature inside the refrigeration shell 4 is reduced by the refrigeration sheet 503, and cold air enters the installation shell 1 for heat dissipation to avoid overheating.

[0027] As a further implementation of the above technical solution: Filter screens 6 are embedded on both sides of the outer wall of the refrigeration shell 4. A scraper 7 is fixed at the position where the outer wall of the worm 504 is in contact with the filter screen 6. The filter screen 6 is convenient for filtering the flowing gas, filtering out dust and impurities to avoid entry and affecting the internal components. At the same time, a filter screen is embedded in the reserved hole opened at the top of the installation shell 1, which is convenient for air outflow and avoids dust entry.

[0028] During specific implementation, with the motor 502 fixed by the mounting frame 501, the worm 504 rotates stably. The worm 504 pushes the worm wheel 505 to drive the rotating shaft 506 to rotate, enabling the fan blade 507 to rotate inside the mounting shell 1. This facilitates the diffusion of the air cooled by the cooling fin 503 inside the refrigeration shell 4 into the mounting shell 1 for cooling and heat dissipation, and the air is pushed out of the mounting shell 1, improving air circulation and achieving a heat dissipation effect. When the worm 504 rotates, it drives the scraper 7 to rotate in conjunction with the filter net 6, facilitating the scraping of adsorbed dust and impurities to avoid blockage and affecting air circulation.

[0029] As a further implementation of the above technical solution: A cover plate 8 is fixed to the front end of the mounting shell 1 by bolts. A pressing block 9 is fixed to the outer wall of the cover plate 8 facing the acquisition and processing module 3. A buzzer 10 is embedded at the top of the mounting shell 1. After the acquisition and processing module 3 detects a problem through its own monitoring, it sends an intelligent response alarm message via wireless network technology to make the buzzer 10 give an early warning, so as to monitor and feedback on the faults of the escalator. After the cover plate 8 and the mounting shell 1 are closed, the acquisition and processing module 3 is limited by the pressing block 9 to avoid excessive shaking.

[0030] As a further implementation of the above technical solution: A stabilizing mechanism 11 is provided below the acquisition and processing module 3. The stabilizing mechanism 11 includes a first damping spring 1102. The first damping spring 1102 is fixed to the bottom end of the clamping plate 2. One end of the first damping spring 1102 is connected to a pressing plate 1101. A rubber pad 1103 is connected to the position corresponding to the pressing plate 1101 at the bottom end inside the mounting shell 1. When the connection cable is connected to the connection port below the front end of the acquisition and processing module 3, the first damping spring 1102 elastically pushes the pressing plate 1101 to press these cables tightly, avoiding shaking and causing the cables to become loose.

[0031] As a further implementation of the above technical solution: The stabilizing mechanism 11 further includes a limiting shell 1104. The limiting shell 1104 is fixed to the rear end of the mounting shell 1. A plurality of limiting grooves 1105 are opened at the bottom end of the limiting shell 1104. A second damping spring 1106 is embedded inside the limiting groove 1105. One end of the second damping spring 1106 is connected to a clamping block 1107. Before the cable enters the mounting shell 1, it enters the limiting groove 1105 opened in the limiting shell 1104, and the second damping spring 1106 pushes the clamping block 1107 to elastically clamp it, avoiding loosening.

[0032] As a further implementation of the above technical solution: The rubber pad 1103 is adhesively connected to the mounting shell 1. The rubber pad 1103 is in close contact with the pressing plate 1101. The rubber pad 1103 prevents the cable from being overly clamped and damaged, and at the same time has insulation to avoid electric leakage.

[0033] During specific implementation, after the cable enters the installation shell 1 and is connected to the acquisition and processing module 3, the pressing plate 1101 is elastically pushed by the first damping spring 1102 to tightly press the cable against the rubber pad 1103. At the same time, the pressing plate 1101 is provided with a reserved groove corresponding to the cable, which can limit the cable to prevent it from shaking and loosening. Before the cable enters the installation shell 1, it passes through the limiting shell 1104 through the limiting groove 1105, and the clamping block 1107 is elastically pushed by the second damping spring 1106 to clamp the cable, preventing it from shaking and vibrating and becoming detached and loose.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
