[0001] The utility model relates to the technical field of intelligent tools and apparatuses, in particular to a leaning single ladder with intelligent monitoring and alarm. Background Art

[0002] Leaning single ladder, as a common type of portable ladder, is a ladder consisting of only one section, which needs to lean on other fixed objects (such as walls, trees, etc.) to be used stably. According to the specific structure and use, the leaning single ladder can be further subdivided into different types, such as single-piece leaning step ladder, single-piece leaning pedal ladder, etc. Leaning single ladder is widely used in household, industrial, construction and other fields, such as power distribution maintenance construction, equipment maintenance, home decoration, cleaning operations and other occasions that require climbing. Its portability and stability make it an indispensable tool in many occasions.

[0003] Article 10.19 of the revised draft of the Electric Power Safety Work Regulations (Line Section) (Q / GDW1799.2-2013) stipulates: "The rungs of a rigid ladder should be embedded in the pillars, the distance between the steps should not be greater than 30cm, and a height limit sign should be set 1m from the top of the ladder for leaning single ladders. When working with leaning single ladders, the angle between the ladder and the ground should be between 65 and 75 degrees, and someone should be supported to prevent instability and falling. It is forbidden to move the ladder when someone is on it."

[0004] The traditional leaning single ladder includes a single ladder combination frame composed of two vertical supporting pillars and several cross bars connecting the pillars. No matter what material it is made of, it does not have the status and prompt functions of detecting whether it is safe and reliable during use, supporting and monitoring, and whether the height limit line has been crossed. It cannot play the safety control function of prohibiting unsupported operations to prevent unstable falls and exceeding the height limit line. Therefore, a leaning single ladder with intelligent monitoring and alarm is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a leaning single ladder with intelligent monitoring and alarm, which has the advantages of monitoring and alarm, and solves the problem that the traditional leaning single ladder does not have the status and prompt functions of detecting whether it is safe and reliable in use, supporting and monitoring, and whether the height limit line has been crossed, and it does not have the safety control function of prohibiting unsupported operations to prevent instability and falling, and exceeding the height limit line.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leaning single ladder with intelligent monitoring and alarm, comprising two single ladder pillars, a plurality of single ladder cross bars are fixedly connected between the two single ladder pillars, and a detection alarm mechanism is arranged on the two single ladder pillars and the plurality of single ladder cross bars;

[0007] The detection alarm mechanism includes a plurality of acquisition boards located on the single ladder pillar, a charging power supply for power supply is provided on the single ladder pillar, an inclination sensor for measuring angles is provided on the single ladder pillar, a plurality of the single ladder cross bars are provided with cross bar belt-shaped pressure sensors, two of the single ladder pillars are provided with pillar belt-shaped pressure sensors, a connecting wire fixed in the pressure bar is provided on the left single ladder pillar, and a main controller and an audible and visual alarm are provided on the left single ladder pillar.

[0008] Furthermore, the bottoms of the two single ladder pillars are fixedly connected with anti-skid pads for stably installing the ladder.

[0009] Furthermore, a one-meter height limit line is provided on each of the two single-ladder pillars.

[0010] Furthermore, the single ladder pillar is provided with an inclination sensor, a collection board, a pillar belt pressure sensor, a connecting wire fixed in the pressure line, a main controller and an audible and visual alarm.

[0011] Furthermore, a crossbar belt-shaped pressure sensor is provided on the single ladder crossbar.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The leaning ladder with intelligent monitoring and alarm can automatically detect whether the installation angle of the ladder is within the specified range, the position of the climber on the ladder, and the status of the ladder support pillars supported by the guardian through the detection and alarm mechanism, so as to realize the intelligent detection of whether the leaning ladder meets the safety regulations, and use sound and light alarms to remind the safety control functions such as whether the installation angle of the ladder is correct, prohibiting climbing without guardianship support, stopping ladder operations if guardianship support is not in place, and prohibiting operations exceeding the height limit line.

[0014] 2. The leaning ladder with intelligent monitoring and alarm can solve the problem of workers using the leaning ladder. It can intelligently detect whether the angle of the ladder during installation is within the specified range, the position of the people on the ladder, the status of the ladder pillar supported by the guardian, and the alarm prompt. That is, when a worker climbs the ladder to work, the detection device automatically starts to detect whether the angle of the ladder installation is within the specified range, and prompts the guardian to correctly support the ladder pillar to prevent the ladder from becoming unstable and falling. When the person on the ladder climbs above the one-meter height limit line from the top of the ladder, the alarm prompts him to retreat to work below the height limit line.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 2 In this embodiment, a leaning single ladder with intelligent monitoring and alarm includes two single ladder pillars 1, a plurality of single ladder cross bars 2 are fixedly connected between the two single ladder pillars 1, and detection and alarm mechanisms are arranged on the two single ladder pillars 1 and the plurality of single ladder cross bars 2.

[0020] The detection alarm mechanism includes a plurality of collection boards 7 located on the single-ladder pillar 1, an inclination sensor 6 for measuring an angle is arranged on the single-ladder pillar 1, a plurality of single-ladder cross bars 2 are provided with cross bar belt pressure sensors 8, two single-ladder pillars 1 are provided with pillar belt pressure sensors 10, and the single-ladder pillar 1 is provided with a pressure bar 12 for fixing the connecting wires, a main controller 9, and an audible and visual alarm 11.

[0021] It should be noted that the detection alarm mechanism automatically detects whether the installation angle of the single ladder is within the specified range, the position of the ladder operator on the single ladder, and the status of the guardian supporting the single ladder pillar, so as to realize intelligent detection of whether the leaning single ladder meets the safety regulations, and uses sound and light alarms to prompt safety control functions such as whether the installation angle of the single ladder is correct, prohibiting climbing the ladder without guardianship support, stopping ladder operations if guardianship support is not in place, and prohibiting operations exceeding the height limit line.

[0022] See also Figures 1 to 2 In this embodiment, the bottoms of the two single ladder pillars 1 are fixedly connected with anti-skid pads 3 for stably installing the ladder.

[0023] It should be noted that, by providing the anti-skid pad 3, the leaning single ladder is prevented from sliding, the friction coefficient between the single ladder support and the ground is enhanced, and the stability of the leaning single ladder during use is increased.

[0024] See also Figures 1 to 2 In this embodiment, a one-meter height limit line 4 is provided on each of the two single-ladder pillars 1 .

[0025] It should be noted that the one-meter height limit line is set according to safety regulations to remind people climbing ladders not to work above the height limit line.

[0026] See also Figures 1 to 2 In this embodiment, a charging power source 5 for power supply is provided on the single ladder support 1.

[0027] It should be noted that the device uses a rechargeable power supply, which can be used repeatedly to reduce the cost of use.

[0028] See also Figures 1 to 2 In this embodiment, the single ladder pillar 1 is provided with an inclination sensor 6, a collection board 7, a main controller 9, a pillar belt pressure sensor 10, an audible and visual alarm 11 and a connecting wire 12 fixed in the pressure line.

[0029] It should be noted that the inclination sensor 6 is mainly responsible for the detection of the installation angle of the single ladder; the acquisition board 7 is mainly responsible for collecting and processing sensor data; the main controller 9 is mainly composed of an I / O control unit, an interface control unit, a power conversion unit, a voice control unit and a communication unit; among which the I / O control unit is mainly responsible for the control of the sound and light alarm, the interface control unit is mainly responsible for the sensor quotation data processing, the power conversion unit is responsible for the conversion from input to power supply of each module, the voice control unit is responsible for voice control, and the communication unit is responsible for equipment upgrades and printing operation information.

[0030] See also Figures 1 to 2 In this embodiment, a crossbar belt-shaped pressure sensor 8 is provided on the single ladder crossbar 2.

[0031] It should be noted that the strip pressure sensor 10 set on the single-ladder pillar 1 and the strip pressure sensor 8 on the single-ladder crossbar 2 are both glued to the surface of the pillar 1 and the crossbar 2 with strong glue to make them integrated. By setting the pressure line 12, the wires connecting the inclination sensor 6, the acquisition board 7, the crossbar strip pressure sensor 8, the main controller 9, the pillar strip pressure sensor 10 and the sound and light alarm 11 and other components are fixed on the inner side between the two columns with the pressure line 12 to prevent the connecting wires from colliding with foreign objects and being damaged. The above measures are to ensure that the traditional use function of the single ladder is not affected after the intelligent detection device is added.

[0032] It should be noted that the distance between the steps is generally 30 cm, so the two strip pressure sensor belts on the single-ladder pillar are generally installed 1.2 to 1.6 meters above the anti-slip pad at the lower end of the single-ladder pillar, that is, on the front side between the 4th to 6th cross sections of the single-ladder from bottom to top, to ensure that guardians of all heights can effectively hold the strip pressure sensor on the single-ladder pillar with both hands for monitoring.

[0033] The working principle of the above embodiment is:

[0034] The leaning single ladder with intelligent monitoring and alarm,

[0035] 1) Charge the smart leaning single ladder before use to ensure sufficient power.

[0036] 2) After the intelligent leaning single ladder is set up at the workplace, when the ladder climber climbs onto the ladder rung 2, the belt pressure sensor 8 fixed on the surface of the ladder rung automatically detects the pressure it is subjected to, and the collection board 7 installed next to the belt pressure sensor 8 collects the information and transmits it to the main controller 9 through the connecting wire, triggering the intelligent monitoring device to start, and the device starts working.

[0037] 3) The inclination sensor 6 installed on the inner side of the ladder support 1 at the bottom of the smart leaning ladder works first. The inclination sensor 6 is fixed parallel to the center line of the ladder support 1. When the ladder is installed at an angle, the inclination sensor 6 deflects and automatically detects the angle a between the ladder support 1 and the center of gravity of the inclination sensor 6. When 90 degrees-65 degrees ≧ a ≧ 90 degrees-75 degrees, it means that the installation angle of the ladder meets the safety regulations that "the angle between the ladder and the ground is between 65 degrees and 75 degrees", and the sound and light alarm 11 does not emit sound and light prompts. When a>90 degrees-65 degrees, it means that "the angle between the ladder and the ground is less than 65 degrees", the angle information of the inclination sensor 6 is transmitted to the main controller 9 through the acquisition board 7, the sound and light alarm 11 at the top of the single ladder is started, the alarm light flashes, and a voice prompt tone of "no climbing, the ladder is installed less than 65 degrees" is issued to remind the staff to get off the ladder and remind the guardian to adjust the installation angle of the single ladder; when a<90 degrees-75 degrees, it means that "the angle between the ladder and the ground is greater than 75 degrees", the angle information of the inclination sensor 6 is transmitted to the main controller 9 through the acquisition board 7, the sound and light alarm 11 at the top of the single ladder is started, the alarm light flashes, and a voice prompt tone of "no climbing, the ladder is installed greater than 75 degrees" is issued to remind the staff to get off the ladder and remind the guardian to adjust the installation angle of the single ladder; until the guardian adjusts the installation angle of the single ladder so that the angle between the single ladder and the ground is between 65 degrees and 75 degrees, the information collected by the acquisition board 7 is within the specified range, and the detection device does not issue an audible and visual alarm prompt signal.

[0038] 4) At the same time, the belt pressure sensor 10 installed on the intelligent leaning single ladder pillar starts detection. When someone is climbing the single ladder, that is, when the belt pressure sensor 8 on the single ladder crossbar is under pressure, if the guardian does not effectively support and hold the single ladder pillar with both hands at the same time, or the support and holding of the single ladder pillar is not standardized (one-hand support or insufficient pressure), or both hands are separated from the support and holding of the single ladder pillar, the two belt pressure sensors 10 installed on the two pillars of the single ladder do not detect the pressure of the guardian supporting the single ladder pillar at the same time, and the detection device transmits the information to the main controller 9 through the acquisition board 7 connected to the belt pressure sensor 10 on the single ladder pillar, triggering the sound and light alarm 11 at the top of the single ladder to work, the alarm light flashes, and a voice prompt tone of "please support, prevent falling" is issued to remind the guardian to support the single ladder pillar correctly. When the guardian holds the two pillars of the ladder with both hands and applies enough pressure to the ladder pillars to prevent the ladder from overturning, the two belt pressure sensors 10 on the pillars simultaneously detect the guardian's supporting pressure, and the acquisition board 7 connected to them transmits the information to the main controller 9, triggering the sound and light alarm 11 to interrupt work, and the sound and light prompt signal stops.

[0039] 5) When the center of gravity of the ladder climber steps on the horizontal rail above the 1-meter height limit line 4 of the leaning single ladder, that is, the center of gravity of the worker enters the 1-meter height limit line, the strip pressure sensor 8 installed on the horizontal rail above the 1-meter height limit line 4 of the single ladder detects the pressure given by the worker, and transmits the information to the main controller 9 through the acquisition board 7 connected thereto, triggering the sound and light alarm 11 at the top of the single ladder to work, the alarm light flashes, and a voice prompt signal of "Do not cross the height limit line, prevent falling" is issued to remind the ladder climber not to cross the height limit line. When the center of gravity of the ladder climber's feet retreats to the horizontal rail of the single ladder below the 1-meter height limit line 4, the strip pressure sensors 8 installed on the horizontal rail above the 1-meter height limit line 4 detect that the pressure given by the worker disappears, and transmits the information to the main controller 9 through the acquisition board 7 connected thereto, triggering the sound and light alarm 11 to interrupt work, and the sound and light alarm signal stops.

[0040] 6) When the ladder climbing worker finishes the climbing operation and returns to the ground, the belt pressure sensors 8 installed on each crossbar of the leaning single ladder automatically detect that the pressure on the ladder disappears and the time lasts for more than 1 minute. The acquisition board 7 collects the information and transmits it to the main controller 9, triggering the detection device to cut off the power supply, and the detection device automatically enters the sleep state.

[0041] The electrical components appearing in the text are all electrically connected to the main controller and the power supply. The control method of the utility model is controlled by the main controller. The control circuit of the main controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
