Description

Technical Field

[0001] This utility model relates to the field of building construction hazard investigation and management by points system, specifically a safety hazard point system management device. Background Technology

[0002] Construction safety management is increasingly adopting a point-based system. Construction safety management mainly involves the management of fire, noise, and dust. Fire management is usually a hazard investigation and management system. In practice, hazard detection devices such as smoke sensors, flame sensors, and temperature sensors are installed at the construction site, and the monitoring data is then transmitted to a back-end terminal or mobile terminal. In order to improve the effectiveness of hazard investigation and monitoring, a hazard investigation point management system has been introduced. That is, when a dangerous situation occurs, points are awarded to the current construction area based on the severity of the situation, and the safety management plan is adjusted based on the points.

[0003] Currently, hazard detection information is usually recorded on paper, in computer files, or on warning boards. These technical methods have a weak warning effect and are not convenient for obtaining hazard score data in a clear and intuitive way. Consequently, it is difficult for construction workers to participate in the implementation of safety hazard investigation, which is not conducive to safe production.

[0004] Therefore, this utility model provides a safety hazard point-based management device. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a safety hazard point-based management device to solve the problems mentioned in the background. This invention has the function of recording various hazards separately, and has the advantages of clearer and more intuitive point recording and accumulation. It makes it easier for construction workers to clearly identify the weak points of safety hazards, thereby encouraging them to develop the habit of participating in hazard investigation and greatly reducing the probability of safety hazards.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a safety hazard point-based management device, comprising a recording board, a rotating shaft and several recording motors located outside the rotating shaft on the front side of the recording board, a ratchet gear fixedly connected to the output shaft of the recording motor, an intermediate gear fixedly connected to the front end of the rotating shaft and meshing simultaneously with the ratchet gears on all the recording motors, a telescopic rod fixedly provided on the front side of the recording board, a vertical scale plate slidably connected to the moving end of the telescopic rod, one side of the vertical scale plate meshing with the intermediate gear, and a control display assembly provided on the front side of the recording board.

[0007] Furthermore, the control and display assembly includes a recording button and a PLC controller electrically connected to the recording button. Each of the recording motors has a recording button fixedly installed on one side, and each of the recording motors is electrically connected to the PLC controller.

[0008] Furthermore, the control and display assembly includes a control box and several recording display screens located on the front side of the control box. The recording motor is equipped with a rotary encoder, and the several recording display screens are electrically connected to the rotary encoders on the several recording motors respectively.

[0009] Furthermore, the control display assembly also includes a total display screen and a total score display screen located on the front side of the control box and close to both ends, respectively, and the PLC controller is electrically connected to the total display screen, the total score display screen and the recording display screen.

[0010] Furthermore, the control and display assembly includes a button area located on the front side of the control box. This button area can control the extension and retraction of the telescopic rod and the resetting of the total display screen, the total score display screen, and the record display screen via a PLC controller.

[0011] Furthermore, the control display assembly includes a limit switch located on the front side of the recording plate near the bottom, at the bottom of the vertical scale plate and electrically connected to the PLC controller.

[0012] Furthermore, a guide plate is welded to the moving end of the telescopic rod, and a slide rail is provided on one side of the guide plate to slide in cooperation with the vertical scale plate. An integral scale is provided on the front side of the vertical scale plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, several recording motors are set on a recording plate, and the output shafts of the recording motors are fixedly connected to ratchet gears. A rotating shaft and an intermediate gear located at one end of the rotating shaft are then set on the recording plate. The intermediate gear meshes simultaneously with the ratchet gears on the recording motors. Each recording motor corresponds to a safety hazard. When each recording motor starts, it drives the intermediate gear to rotate at a certain angle. Finally, a vertical scale plate meshing with the intermediate gear is set on the front side of the recording plate. The vertical scale plate displays the accumulated hazard points based on the rotation of the intermediate gear. In other words, by controlling the rotation of each recording motor, the points for the corresponding safety hazard can be accumulated and then displayed on the vertical scale plate, offering the advantage of clearer and more accurate point recording.

[0015] 2. In this utility model, by setting up a control and display combination, it is convenient to display various hidden dangers separately on the recording display screen, and then accumulate and display the overall hidden danger situation and the overall score, making the safety hazard record more eye-catching and intuitive, enabling construction personnel to more clearly identify the weak links in safe construction, thereby accurately improving the safety awareness of construction personnel.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a safety hazard point-based management device, including a recording board 1. During construction, the recording board 1 is installed at the construction site. This device is used in conjunction with external safety hazard monitoring devices, such as temperature sensors, smoke sensors, flame sensors, noise sensors, etc., installed at the construction site to monitor various safety hazards. These monitoring devices can accurately and promptly record when hazards occur, and then input the recorded data into this device.

[0022] Specifically, a rotating shaft 2 and several recording motors 3 located outside the rotating shaft 2 are arranged on the front side of the recording plate 1. The recording motors 3 are servo motors, and a ratchet 4 is fixedly connected to the output shaft of each recording motor 3. An intermediate gear 21 is fixedly connected to the front end of the rotating shaft 2, meshing simultaneously with the ratchet 4 on all the recording motors 3. Each recording motor 3 corresponds to a safety hazard. The ratchet 4 adopts a common unidirectional gear structure. When a recording motor 3 drives its corresponding ratchet 4 to rotate, the intermediate gear 21 rotates, and the ratchet 4 on the other recording motors 3 will be passively rotated under the transmission of the intermediate gear 21. At this time, the rotation of the intermediate gear 21 records the number of revolutions of the current recording motor 3. When performing point management, the number of revolutions recorded by each recording motor 3 in one recording can be set according to the level of safety hazard. For example, for a fire hazard, the recording motor 3 is set to drive its ratchet 4 to rotate multiple revolutions in one recording, while for a noise hazard with a lower level of safety, the corresponding recording motor 3 is set to drive its ratchet 4 to rotate one revolution in one recording. The rotation of the intermediate gear 21 can accumulate the records of each recording motor 3.

[0023] Furthermore, a telescopic rod 5 is fixedly installed on the front side of the recording plate 1. The moving end of the telescopic rod 5 is slidably connected to a vertical scale plate 6. One side of the vertical scale plate 6 meshes with an intermediate gear 21. The rotation angle of the intermediate gear 21 causes the vertical scale plate 6 to rise. The vertical scale plate 6 displays the integration progress according to the baseline on the recording plate 1. Moreover, intuitively, the higher the vertical scale plate 6 rises, the higher the integration score, and the more times safety hazards occur. Among them, a guide plate 51 is welded to the moving end of the telescopic rod 5. One side of the guide plate 51 has a slide rail 511 that slides with the vertical scale plate 6. The front side of the vertical scale plate 6 has an integration scale 61. The scale on the vertical scale plate 6 uses the top surface of the guide plate 51 as the recording reference surface.

[0024] In this embodiment, a control and display assembly 7 is provided on the front side of the recording board 1. The function of the control and display assembly 7 is to record the number of times various safety hazards occur, the total number of hazards, and the total score for digital display. It is also used to set and control the number of rotations of each recording motor 3 on one side during recording.

[0025] Specifically, the control and display assembly 7 includes a recording button 71 and a PLC controller 72 electrically connected to the recording button 71. Each of the several recording motors 3 has a recording button 71 fixedly installed on one side. One recording button 71 corresponds to one recording motor 3. When the recording button 71 is pressed, the corresponding recording motor 3 runs once. The several recording motors 3 are all electrically connected to the PLC controller 72. The PLC controller 72 sets the number of revolutions of each recording motor 3 in a single start according to the hazard level. For example, one revolution can be set as one minute. The higher the hazard level, the more revolutions the corresponding recording motor 3 will rotate in a single start.

[0026] Furthermore, the control and display assembly 7 includes a control box 73 and several recording display screens 74 located on the front side of the control box 73. The PLC controller 72 can be installed inside the control box 73. A rotary encoder 31 is provided on the recording motor 3. The several recording display screens 74 are electrically connected to the rotary encoders 31 on the several recording motors 3 respectively. Each recording motor 3 records the number of rotations of itself by the rotary encoder 31, and then the rotary encoder 31 transmits the number of rotations to the corresponding recording display screen 74.

[0027] In this embodiment, the control display assembly 7 also includes a total display screen 75 and a total score display screen 76 located on the front side of the control box 73 and close to both ends. The PLC controller 72 is electrically connected to the total display screen 75, the total score display screen 76 and the recording display screen 74. The PLC controller 72 accumulates the number of laps on several recording display screens 74 and displays it as a whole on the total display screen 75. The PLC controller 72 displays the integral corresponding to the total number of laps displayed on the total display screen 75 on the total score display screen 76.

[0028] In this embodiment, the control display assembly 7 includes a button area 78 located on the front side of the control box 73. The button area 78 has multiple buttons, and through the PLC controller 72, it can control the extension and retraction of the telescopic rod 5, as well as the resetting of the total display screen 75, the total score display screen 76, and the recording display screen 74. That is, when it is necessary to recount the hazard points, the telescopic rod 5 is retracted, the vertical scale plate 6 and the intermediate gear 21 separate, and the intermediate gear 21 descends to its initial position using its own weight. Then, the telescopic rod 5 pushes the vertical scale plate 6 to re-engage with the intermediate gear 21. Simultaneously, the button area 78 resets the numbers on the total display screen 75, the total score display screen 76, and the recording display screen 74.

[0029] Furthermore, the control display assembly 7 includes a limit switch 77, which is located on the front side of the recording plate 1 near the bottom. The limit switch 77 is located at the bottom of the vertical scale plate 6 and is electrically connected to the PLC controller 72. When the vertical scale plate 6 descends to the bottom, it will touch the limit switch 77. The limit switch 77 controls the telescopic rod 5 to automatically reset via the PLC controller 72.

[0030] Working Principle: Before use, connect the electrical equipment on this device to an external power supply box, which will then supply power to the device. The recording board 1 is then mounted on a wall or pole at the construction site. During use, the monitoring data of potential hazards at the construction site is periodically entered into this device. During entry, the recording button 71 on the corresponding recording motor 3 is manually pressed according to the hazard level. This starts the current recording motor 3 once, causing the ratchet 4 to drive the intermediate gear 21 to rotate. The intermediate gear 21 then moves the vertical scale plate 6 upwards, and the corresponding recording display screen 74 displays the number of rotations of the recording motor 3. By controlling the other recording motors 3 sequentially in the same manner, the point-based statistical management of safety hazards at the construction site can be achieved.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
