Description

Technical Field

[0001] This utility model relates to the field of building construction protection technology, and in particular to a protective railing. Background Art

[0002] During construction, because the construction area is considered a hazardous area, protective fences are usually installed at the edge of the construction area to prevent unauthorized personnel from entering and to avoid installation accidents. However, traditional protective fences are inadequate in warning and deterring unauthorized personnel from attempting to cross the fence into the construction area, nor can they provide timely reminders to existing workers when such attempts occur, thus exhibiting shortcomings. Utility Model Content

[0003] This utility model relates to a guardrail. When a non-worker attempts to cross the guardrail to enter the construction area, as their hand presses on the guardrail frame for support and prepares to cross, the position between the base and the guardrail will simultaneously change, thereby simultaneously pressing and activating the crossing warning switch. This will immediately trigger a high-decibel buzzer warning, deterring the person from crossing the guardrail into the construction area. It will also warn and remind the workers in the construction area to promptly move to their current location to prevent the non-worker from entering the construction area.

[0004] This utility model provides a guardrail, specifically comprising: a base, the base being a rectangular block structure, with a rectangular groove-shaped insertion slot on the top surface of the base, and a storage slot on each of the left and right sides of the bottom surface of the insertion slot; a protective frame plate with a rectangular frame structure located directly above the base, with a row of protective support plates evenly distributed and fixedly installed in the inner frame area of ​​the protective frame plate, and a warning sign fixedly installed on the front end of the protective support plate; a rectangular block-shaped insertion block fixedly installed on the bottom surface of the protective frame plate, the insertion block being slidably inserted into the insertion slot; a spring support member fixedly connected to each of the left and right sides of the bottom surface of the insertion block, the bottom ends of the two spring support members being fixedly connected to the bottom surfaces of the two storage slots respectively; in the extended state of the spring support members, the bottom surface of the insertion block is higher than the bottom surface of the insertion slot, and the bottom surface of the protective frame plate is also higher than the top surface of the base.

[0005] Furthermore, an embedded groove is formed on the bottom surface of the inner end of the plug slot, and a set of crossover warning switches is fixedly installed on the bottom surface of the inner end of the embedded groove; the crossover warning switch is a tactile switch, and the button end of the crossover warning switch faces upward; when the crossover warning switch is in the unpressed activation state, the top surface of the button end of the crossover warning switch is higher than the bottom surface of the inner end of the plug slot.

[0006] Furthermore, a soft rubber pad is fixedly installed at the center of the bottom end face of the plug-in block; when the soft rubber pad contacts the bottom surface of the inner end of the plug-in groove, the bottom end face of the protective frame plate is higher than the top end face of the base, and the bottom end face of the soft rubber pad presses against the button end of the crossover warning switch, at which time the crossover warning switch is in the pressed start state.

[0007] Furthermore, a reflective warning sticker is fixedly adhered to the front end of the base; a mounting plate is fixedly installed on both the left and right sides of the front and rear ends of the base, and a fixed insertion hole is opened on the top surface of the mounting plate, which extends through the bottom surface; a microcontroller and a battery electrically connected to it are installed inside the base, and a crossover warning switch is electrically connected to the microcontroller; an alarm, an on / off switch, a power indicator, and a charging port are installed on the rear end of the base, and the alarm and the on / off switch are electrically connected to the microcontroller. The alarm is a buzzer; the power indicator and the charging port are electrically connected to the battery; when the crossover warning switch is in the pressed start state, the crossover warning switch feeds a feedback signal to the microcontroller, and the microcontroller controls the alarm to start.

[0008] Furthermore, an L-shaped support plate is fixedly installed on the rear end face of the base, and the short end of the L-shaped support plate is fixedly connected to the rear end face of the base; a set of motors is fixedly installed on the long end rear end face of the L-shaped support plate, and the motors are electrically connected to the microcontroller; an active component is provided between the long end front face of the L-shaped support plate and the rear end face of the base, the active component is an incomplete gear, and the motor shaft end passes through the long end of the L-shaped support plate and is fixedly connected to the active component.

[0009] Furthermore, a rack is fixedly installed on the rear end face of the protective frame plate, and the rack is positioned adjacent to the driving component. When the motor is not running, the driving component does not mesh with the rack. The base also has a timing module, which is electrically connected to the microcontroller. The timing value of the timing module is not limited and can be set according to requirements. When the timing value of the timing module is reached, the timing module sends a feedback signal to the microcontroller, and the microcontroller controls the motor shaft to rotate counterclockwise one revolution. When the motor shaft rotates counterclockwise one revolution, the driving component meshes with the rack. When the driving component is about to disengage from the rack, the soft rubber pad contacts the bottom surface of the inner end of the insertion slot.

[0010] This utility model provides a protective railing with the following beneficial effects:

[0011] The base and protective frame of this utility model adopt a sliding plug-in connection design, with spring supports as connecting components. When a non-worker attempts to cross the guardrail into the construction area, their hand presses against the protective frame for support as they prepare to cross. Simultaneously, the position between the base and the protective frame changes, triggering the crossing warning switch to immediately activate a high-decibel buzzer warning. This serves as a deterrent to the person in question, preventing them from crossing the guardrail into the construction area. At the same time, the high-decibel buzzer also serves as a warning to workers within the construction area, prompting them to promptly return to their current location to prevent unauthorized personnel from entering the construction area, thus ensuring safety and preventing accidents.

[0012] This utility model, in conjunction with a timer module that allows for the setting of specific time periods, can periodically monitor whether or not personnel have crossed the guardrail. The monitoring function uses a drive mechanism that meshes with a rack and pinion to simulate non-staff members pressing against the guardrail frame, thus detecting whether or not personnel have crossed the guardrail. When the alarm emits a high-decibel beep during the specific time period of the timer module, staff can determine that the monitoring function is operating normally. If the alarm does not emit a high-decibel beep, staff can determine that the monitoring function has malfunctioned and requires immediate repair. Attached Figure Description

[0025] Example: Please refer to Figures 1 to 5 :

[0026] This utility model proposes a guardrail, comprising: a base 1, which is a rectangular block structure; a rectangular groove 1011 is formed on the top surface of the base 1; and a storage groove 1012 is formed on both the left and right sides of the bottom surface of the inner end of the groove 1011; a rectangular frame plate 2 is provided directly above the base 1; a row of protective support plates 201 are uniformly distributed and fixedly installed in the inner frame area of ​​the protective frame plate 2; a warning sign 202 is fixedly installed on the front end of the protective support plate 201; a rectangular block 203 is fixedly installed on the bottom surface of the protective frame plate 2, and the block 203 is slidably inserted into the groove 1011; a spring support member 205 is fixedly connected to each of the left and right sides of the bottom surface of the block 203, and the bottom ends of the two spring support members 205 are respectively fixedly connected to the bottom surfaces of the inner ends of the two storage grooves 1012; when the spring support members 205 are extended, the block 203... The bottom surface of the 3rd end plate is higher than the inner bottom surface of the plug slot 1011, and the bottom surface of the protective frame plate 2 is also higher than the top surface of the base 1; an embedded groove 1013 is opened on the inner bottom surface of the plug slot 1011, and a set of crossover warning switches 1014 are fixedly installed on the inner bottom surface of the embedded groove 1013; the crossover warning switch 1014 is a tactile switch, and the button end of the crossover warning switch 1014 faces upward; when the crossover warning switch 1014 is in the unpressed state, the top surface of the button end of the crossover warning switch 1014 is higher than the inner bottom surface of the plug slot 1011; a soft rubber pad 206 is fixedly installed at the center of the bottom surface of the plug block 203; when the soft rubber pad 206 contacts the inner bottom surface of the plug slot 1011, the bottom surface of the protective frame plate 2 is higher than the top surface of the base 1, and the bottom surface of the soft rubber pad 206 presses against the button end of the crossover warning switch 1014, at which time the crossover warning switch 1014 is in the pressed state.

[0027] In this embodiment, a reflective warning sticker 101 is fixedly adhered to the front end face of the base 1; a mounting plate 102 is fixedly installed on both the left and right sides of the front and rear ends of the base 1, and a fixed insertion hole 103 is opened on the top surface of the mounting plate 102, which passes through its bottom end face; a microcontroller 1017 and a battery 1016 electrically connected to it are provided inside the base 1, and the battery 1016 is electrically connected to the microcontroller 1017 across the warning switch 1014; an alarm 104, an on / off switch 105, a power display 106 and a charging port 107 are installed on the rear end face of the base 1, and the alarm 104 and the on / off switch 105 are connected to the microcontroller 1017. 017 is electrically connected, and the alarm 104 is a buzzer; the power display 106 and the charging port 107 are electrically connected to the battery 1016; when the crossover alarm switch 1014 is in the pressed start state, the crossover alarm switch 1014 feeds a feedback signal to the microcontroller 1017, and the microcontroller 1017 controls the alarm 104 to start; an L-shaped support plate 108 is fixedly installed on the rear end face of the base 1, and the short end of the L-shaped support plate 108 is fixedly connected to the rear end face of the base 1; a set of motors 109 is fixedly installed on the long end rear end face of the L-shaped support plate 108, and the motors 109 are electrically connected to the microcontroller 1017. The L-shaped support plate 108 is connected to the base 1 by an active component 1010, which is an incomplete gear. The shaft of the motor 109 passes through the long end of the L-shaped support plate 108 and is fixedly connected to the active component 1010. A rack 204 is fixedly installed on the rear end of the protective frame plate 2, and the rack 204 is positioned adjacent to the active component 1010. When the motor 109 is not running, the active component 1010 does not mesh with the rack 204, so when the protective frame plate 2 is pressed down, the active component 1010 will not cause obstruction. The base 1 also has a timing mechanism. Module 1015, the timing module 1015 is electrically connected to the microcontroller 1017. The timing value of the timing module 1015 is not limited and can be set according to requirements. When the timing value of the timing module 1015 is reached, the timing module 1015 sends a feedback signal to the microcontroller 1017, and the microcontroller 1017 controls the shaft end of the motor 109 to rotate counterclockwise one revolution. When the shaft end of the motor 109 rotates counterclockwise one revolution, the driving element 1010 meshes with the rack 204 for transmission. When the driving element 1010 is about to disengage from the rack 204, the soft rubber pad 206 contacts the bottom surface of the inner end of the insertion slot 1011.

[0028] The working principle of this embodiment:

[0029] This practical guardrail is installed at the edge of the construction area. During installation, fasteners such as ground nails can be inserted through the fixing holes 103 on the mounting plate 102 and fixed to the ground to fix the base 1. During installation, the warning sign 202 faces the outside of the construction area.

[0030] When a non-worker ignores the warning sign 202 and attempts to cross this protective barrier into the construction area, their hand presses against the protective frame plate 2 for support. As they prepare to cross the protective frame plate 2, the protective frame plate 2 will move downwards under the pressure of the non-worker. At this time, the plug block 203 moves downwards simultaneously along the plug groove 1011, causing the soft rubber pad 206 to contact the bottom surface of the inner end of the plug groove 1011. When the soft rubber pad 206 contacts the bottom surface of the inner end of the plug groove 1011, the bottom surface of the soft rubber pad 206 presses against the crossing warning switch 101. At button 4, the crossover warning switch 1014 is in the pressed and activated state. The crossover warning switch 1014 sends a feedback signal to the microcontroller 1017, which controls the alarm 104 of the buzzer to be activated. The high-decibel buzzer of the alarm 104 serves as a warning and deterrent to the personnel in the current situation, preventing them from crossing the guardrail and entering the construction area. At the same time, the high-decibel buzzer also serves as a warning and reminder to the workers in the construction area, so that they can go there in time to prevent non-workers from entering the construction area.

[0031] Through the timing design of the timing module 1015, the operator can set a specific time period. When the timing value of the timing module 1015 is reached, the timing module 1015 sends a feedback signal to the microcontroller 1017. The microcontroller 1017 controls the shaft end of the motor 109 to rotate counterclockwise one revolution. When the shaft end of the motor 109 rotates counterclockwise one revolution, its driving actuator 1010 meshes with the rack 204, thereby driving the rack 204 to move downward, so as to synchronously drive the protective frame plate 2 to move downward, to simulate a person's hand pressing on the protective frame plate 2. When the driving actuator 1010 is about to engage with the rack... When tooth 204 is disengaged, the soft rubber pad 206 contacts the bottom surface of the inner end of the insertion slot 1011. Therefore, as mentioned above, if the monitoring function of this utility for whether or not personnel are crossing the guardrail is in normal operation, the alarm 104 will emit a high-decibel buzzer so that the staff can know that the monitoring function for whether or not personnel are crossing the guardrail is in normal operation. However, if the alarm 104 does not emit a high-decibel buzzer during a specific time period of the timing module 1015, the staff can determine that the monitoring function for whether or not personnel are crossing the guardrail has malfunctioned and needs to be repaired in time.
