Description

Technical Field

[0001] The present invention relates to the technical field of ladders, and in particular to a safety ladder climbing device that can prevent unmanned ladders from being used in high-altitude operations. Background Art

[0002] At present, in some occasions with limited environment or temporary maintenance, there is no fixed climbing ladder, so it is often necessary to work on a temporary ladder when working at height. Two people are required to work together, with the climber working at the top of the ladder and the ground person holding the ladder. When the height exceeds 2 meters, if the ground person fails to perform his duties conscientiously after climbing the ladder and leaves the ladder to do other work, and the climber fails to notice it, it is easy to cause the ladder to slip or roll over, causing casualties to the people working at height on the ladder, resulting in safety accidents. Summary of the invention

[0003] The present invention provides a safety ladder climbing device to prevent unmanned climbing of ladders during high-altitude operations, so as to solve the problems in the prior art that climbing personnel fail to pay enough attention and ground personnel lack vigilance and fail to climb the ladders carefully, which easily lead to safety accidents.

[0004] In order to solve the above-mentioned problems, the present invention provides a safety ladder device to prevent unmanned ladders from being used in high-altitude operations, including a ladder body, a detection unit, an alarm unit and a controller, wherein the detection unit, the alarm unit and the controller are all installed on the ladder body, and the detection unit and the alarm unit are all electrically connected to the controller; wherein the detection unit is installed in the area where ground personnel hold the ladder body by hand, and when a climber climbs to the top of the ladder body, the detection unit is used to detect whether there is a ground personnel holding the ladder body by hand, and the detection information of the detection unit is transmitted to the controller, and when the detection unit detects that there is no ground personnel holding the ladder body by hand, the controller controls the alarm unit to send an alarm message to prompt the climber and the ground personnel.

[0005] Furthermore, the ladder body includes two vertical beams arranged in parallel and multiple horizontal beams arranged between the two vertical beams. The detection part includes at least two pressure sensors. A pressure sensor is arranged on the outside of each vertical beam. When the hand of a ground person contacts the pressure sensor, the pressure sensor detects that the ground person is holding the ladder body.

[0006] Furthermore, a plurality of pressure sensors are disposed on the outer side of each vertical beam, and the plurality of pressure sensors are distributed along the height direction of the vertical beam and cover the area where the ground personnel hold the vertical beam.

[0007] Furthermore, the vertical beam is a circular tube, and the pressure sensor is in the shape of an arc-shaped piece, and matches the shape of the outer wall of the vertical beam.

[0008] Furthermore, the safety ladder climbing device for preventing unmanned escalators from working at heights also includes an adhesive layer, and the pressure sensor is adhered to the vertical beam through the adhesive layer.

[0009] Furthermore, the safety ladder device for preventing unmanned ladders from working at heights also includes a proximity sensor, which is arranged on the top of the ladder body. The proximity sensor is used to detect whether the climber has climbed to the top of the ladder body. The proximity sensor is electrically connected to the controller. When the proximity sensor detects that the climber has climbed to the top of the ladder body, the controller controls the alarm unit to issue a reminder message. The reminder message is used to remind the ground personnel to hold the ladder body by hand. When the ground personnel hold the ladder body by hand, the alarm unit stops issuing the reminder message. When the ground personnel hold the ladder body by hand and then let go of the handhold, the alarm unit issues an alarm message.

[0010] Furthermore, the alarm unit includes a warning light and / or a speaker.

[0011] Furthermore, the safety ladder climbing device for preventing unmanned escalators from working at heights also includes a mounting box and a camera. The mounting box is mounted on the ladder body, the camera is mounted on the mounting box, the camera is electrically connected to the controller, and the camera is used to photograph the area where the lower part of the ladder body is located.

[0012] Furthermore, the ladder body includes two parallel vertical beams and a plurality of horizontal beams arranged between the two vertical beams. The safety ladder device for preventing unmanned ladders from operating at heights also includes a strip of Velcro, which is installed in a mounting box and wrapped around the vertical beams.

[0013] Furthermore, the safety ladder climbing device for preventing unmanned escalators from working at heights also includes a battery and a power supply switch, both of which are installed on the ladder body. The battery supplies power to the detection part, the alarm part and the controller through the power supply circuit, and the power supply switch is used to turn on and off the power supply circuit.

[0014] By applying the technical solution of the present invention, a safety ladder device for preventing unmanned ladders from being used in height operations is provided, comprising a ladder body, a detection unit, an alarm unit and a controller, wherein the detection unit, the alarm unit and the controller are all installed on the ladder body, and the detection unit and the alarm unit are all electrically connected to the controller; wherein the detection unit is installed in the area where ground personnel hold the ladder body by hand, and when a climber climbs to the top of the ladder body, the detection unit is used to detect whether there is a ground personnel holding the ladder body by hand, and the detection information of the detection unit is transmitted to the controller, and when the detection unit detects that there is no ground personnel holding the ladder body by hand, the controller controls the alarm unit to send an alarm message to prompt the climber and the ground personnel.

[0015] In this scheme, the ladder body is an important tool for working at heights, and usually requires support and assistance from ground personnel. Without ground personnel holding the ladder, the risk of falling of the climbers will increase. Especially when working at heights, it is not enough to rely solely on the stability of the ladder body itself. This device monitors whether there are ground personnel holding the ladder body through the detection unit, and alarms the climbers and ground personnel through the alarm unit to remind the ground personnel that they have not provided sufficient support, and can remind the climbers to correct the working status in time, which can effectively prevent the climbers from falling and other dangerous situations without ground support during the high-altitude operation. This device combines the dual safety protection of ground personnel and high-altitude workers. For climbers, in addition to ensuring their own work safety, they must also rely on the support of ground personnel. For ground personnel, the device's alarm can remind them to always pay attention and participate in the operation, thereby avoiding dereliction of duty caused by failure to pay attention, and improving safety.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1 to Figure 2 As shown, an embodiment of the present invention provides a safety ladder device for preventing unmanned escalators from being used in height operations, comprising a ladder body 3, a detection unit, an alarm unit 8 and a controller, wherein the detection unit, the alarm unit 8 and the controller are all installed on the ladder body 3, and the detection unit and the alarm unit 8 are all electrically connected to the controller; wherein the detection unit is installed in the area where ground personnel hold the ladder body 3 by hand, and when a climber climbs to the top of the ladder body 3, the detection unit is used to detect whether there is a ground personnel holding the ladder body 3 by hand, and the detection information of the detection unit is transmitted to the controller, and when the detection unit detects that there is no ground personnel holding the ladder body 3 by hand, the controller controls the alarm unit 8 to send out an alarm message to prompt the climber and the ground personnel.

[0031] In this embodiment, the ladder is an important tool for working at heights, which usually requires support and assistance from ground personnel. Without the support of ground personnel, the risk of falling of the climbers will increase. Especially when working at heights, it is not enough to simply rely on the stability of the ladder body 3. The device monitors whether there are ground personnel holding the ladder body 3 by hand through the detection unit, and alarms and reminds the climbers and ground personnel through the alarm unit 8, reminding the ground personnel that they have not provided sufficient support, and can remind the climbers to correct the working status in time, which can effectively prevent the climbers from falling and other dangerous situations without ground support during the high-altitude operation. The device combines the dual safety protection of ground personnel and high-altitude workers. For the climbers, in addition to ensuring the safety of their own work, they must also rely on the support of ground personnel. For the ground personnel, the alarm of the device can remind them to pay attention and participate in the operation at all times, thereby avoiding failure to pay attention and causing dereliction of duty, thereby improving safety.

[0032] like Figure 1 As shown, the ladder body 3 includes two vertical beams arranged in parallel and multiple horizontal beams arranged between the two vertical beams. The detection part includes at least two pressure sensors 4. A pressure sensor 4 is arranged on the outside of each vertical beam. When the hand of a ground person touches the pressure sensor 4, the pressure sensor 4 detects that the ground person is holding the ladder body 3.

[0033] The safety ladder climbing device for preventing unmanned ladders from working at heights can be applied to the power industry for the maintenance of power equipment. The ladder body 3 has an insulating effect. The material of the ladder body 3 can be bamboo, wood or plastic, or the material of the ladder body 3 can be metal and the metal material can be coated with insulating materials such as plastic.

[0034] In this embodiment, by installing a pressure sensor 4 on the outside of each vertical beam, it is possible to accurately detect whether a ground person is in contact with the ladder body 3. The pressure sensor 4 can sense the pressure change caused by the contact of the ground person's hand. If a ground person holds the ladder body 3, the pressure sensor 4 can respond quickly and transmit a signal. If it is detected that no one is holding the ladder, the controller will control the alarm unit 8 to sound an alarm, thereby reducing safety issues caused by human negligence, ensuring the real-time and accuracy of the detection, increasing the safety of operations at heights, and ensuring sufficient safety protection during the operation.

[0035] like Figure 1 As shown, a plurality of pressure sensors 4 are arranged on the outer side of each vertical beam, and the plurality of pressure sensors 4 are distributed along the height direction of the vertical beam and cover the area where the ground personnel hold the vertical beam.

[0036] In this embodiment, by distributing multiple pressure sensors 4 along the height direction of the vertical beam, the detection range can be effectively expanded. Regardless of whether the position of the ground personnel holding the ladder body 3 is high or low, the pressure sensor 4 can cover it, thereby ensuring that the hand contact of the ground personnel at different positions can be accurately detected, reducing the risk of missed detection due to different handholding positions of the ground personnel. Multiple pressure sensors 4 are distributed at different heights of the vertical beam, which can also enhance the fault tolerance of the device. Even if some pressure sensors 4 fail or work abnormally, other pressure sensors 4 can still work normally, ensuring that the function will not be lost due to the failure of some pressure sensors 4, thereby improving the overall reliability and stability.

[0037] like Figure 1 As shown, the vertical beam is a round tube, and the pressure sensor 4 is in the shape of an arc sheet, and matches the shape of the outer wall of the vertical beam. The pressure sensor 4 can be a flexible pressure sensor.

[0038] In this embodiment, the shape of the circular tube-shaped vertical beam matches the shape of the arc-shaped sheet-shaped pressure sensor 4, so that they can fit more closely, ensuring that the pressure sensor can completely cover the entire surface of the vertical beam, and the pressure sensor 4 can accurately sense the contact pressure of the ground personnel's hands, reducing the detection error that may be caused by shape mismatch, and ensuring the accuracy and sensitivity of the detection signal. In addition, the shape of the circular tube-shaped vertical beam matches the shape of the arc-shaped sheet-shaped pressure sensor 4, which can keep the pressure sensor 4 stably fixed on the surface of the vertical beam and is not easy to fall off or move.

[0039] like Figure 2 As shown, the safety ladder climbing device for preventing unmanned escalators from working at heights further includes an adhesive layer 2, and the pressure sensor 4 is adhered to the vertical beam through the adhesive layer 2.

[0040] In this embodiment, the pressure sensor 4 is pasted on the vertical beam using the adhesive layer 2. The operation process is simple and the installation is easy. The pressure sensor 4 can be quickly and accurately pasted to the specified position through the adhesive layer 2 without drilling or other complicated fixing operations. It not only reduces the installation time, but also reduces the processing requirements for the ladder body 3, saving production and maintenance costs. The adhesive layer 2 can also serve as a buffer medium, which can effectively reduce the stress when the pressure sensor 4 contacts the vertical beam. Especially during high-frequency vibration or use, the adhesive layer 2 can effectively disperse the contact pressure and avoid damage to the surface of the pressure sensor 4 due to excessive local force. Moreover, when the pressure sensor 4 needs to be replaced or disassembled, it can be operated by opening the adhesive layer 2. The whole process is easy and simple, which improves the overall flexibility.

[0041] like Figure 1 As shown, the safety ladder device for preventing unmanned escalators from working at heights also includes a proximity sensor 1, which is arranged on the top of the ladder body 3. The proximity sensor 1 is used to detect whether the climber has climbed to the top of the ladder body 3. The proximity sensor 1 is electrically connected to the controller. When the proximity sensor 1 detects that the climber has climbed to the top of the ladder body 3, the controller controls the alarm unit 8 to issue a reminder message. The reminder message is used to remind the ground personnel to hold the ladder body 3 by hand. When the ground personnel hold the ladder body 3 by hand, the alarm unit 8 stops issuing the reminder message. When the ground personnel hold the ladder body 3 by hand and then let go of the hand, the alarm unit 8 issues an alarm message.

[0042] In this embodiment, the proximity sensor 1 is arranged at the top of the ladder body 3, which can sense the climbing status of the climber and is used to detect whether the climber has climbed to the top. Once it is detected that the climber has reached the top, the controller controls the alarm unit 8 to issue a reminder message, providing a reminder to the ground personnel to prevent the danger caused by not noticing the position of the climber. Through the cooperation of the proximity sensor 1, the alarm unit 8 and the pressure sensor 4, the issuance of the reminder message can be adjusted according to whether the ground personnel hold the ladder body 3. When the ground personnel hold the ladder body 3, the alarm unit 8 will stop issuing the reminder message to avoid unnecessary interference; and when the ground personnel leave the ladder body 3, the alarm unit 8 will re-issue the alarm message to remind the ground personnel not to leave the ladder body 3 to avoid the risk of high-altitude operations due to negligence. In this way, false alarms can be avoided to the greatest extent, ensuring that the alarm unit 8 is only activated when necessary.

[0043] Specifically, the alarm unit 8 includes a warning light and / or a speaker. In this embodiment, the alarm unit 8 can be a warning light, which usually uses bright colors and can provide obvious visual signals in the environment of high-altitude operations, especially in a noisy environment. When it is detected that the ground personnel have not taken the ladder, the warning light can effectively attract the attention of the staff and prompt them to perform necessary safety operations in a timely manner.

[0044] Optionally, the alarm unit 8 can also be a speaker, which can transmit a sound alarm. The alarm sound can be quickly spread to the working area to ensure that the warning information can be heard in time. Even when the operating personnel are in a remote location, the sound of the speaker can ensure that the alarm is clearly received.

[0045] Optionally, the alarm unit 8 can also be a combination of a warning light and a loudspeaker. Through the combined use of sound and light source, it provides both visual and auditory alarm modes, which can play a stronger role in environments with obstructed vision or high noise, and can ensure that the alarm information is conveyed quickly and clearly, thereby reducing the response time.

[0046] like Figure 1 As shown, the safety ladder climbing device for preventing unmanned escalators from working at heights also includes an installation box 5 and a camera 6. The installation box 5 is installed on the ladder body 3, and the camera 6 is installed on the installation box 5. The camera 6 is electrically connected to the controller, and the camera 6 is used to shoot the area where the lower part of the ladder body 3 is located.

[0047] In this embodiment, the device also includes an installation box 5 and a camera 6. The camera 6 is installed on the installation box 5 and is used to photograph the area where the lower part of the ladder body 3 is located. It can monitor the lower area of ​​the ladder body 3 in real time. When the ground personnel do not hold the ladder body 3 correctly or are not in the working area, the camera 6 can detect it through image recognition and feed it back to the controller. The controller controls the alarm unit 8 to immediately sound an alarm to ensure safety during the operation.

[0048] like Figure 1 As shown, the ladder body 3 includes two parallel vertical beams and a plurality of horizontal beams arranged between the two vertical beams. The safety ladder device for preventing unmanned escalators from working at heights also includes a strip of Velcro 7, which is installed in the installation box 5 and wrapped around the vertical beams.

[0049] In this embodiment, the Velcro 7 is wrapped around the vertical beam and installed on the installation box 5, which simplifies the connection process between the ladder body 3 and the installation box 5, making the installation box 5 installed on the ladder body 3 simpler and more flexible, reducing the installation time, and facilitating later maintenance and adjustment. The Velcro 7 is wrapped around the vertical beam, which can provide a stable fixing force for the entire installation box 5, preventing the installation box 5 and the camera 6 and other components from loosening or displacement during use. Moreover, the Velcro 7 can adapt to vertical beams of different sizes and shapes, can adapt to different environments and usage requirements, and enhance the overall flexibility.

[0050] Furthermore, the safety ladder climbing device for preventing unmanned escalators from working at heights also includes a battery and a power supply switch, both of which are installed on the ladder body 3. The battery supplies power to the detection part, the alarm part 8 and the controller through the power supply circuit, and the power supply switch is used to turn on and off the power supply circuit.

[0051] In this embodiment, the storage battery enables the detection unit, the alarm unit 8 and the controller to operate independently without an external power supply. In some high-altitude working environments, it may be far away from the external power supply, or in some cases, it is impossible to access a stable power supply. At this time, the storage battery can provide an independent power supply to ensure that the components in the device can always work, thereby improving the reliability and adaptability of the device. The power switch can conveniently control the on and off of the power supply circuit, and can be switched when necessary. Moreover, when a danger or abnormal situation occurs during the operation of the operator, the alarm unit 8 needs to work immediately and send out a warning signal to remind the operator to take timely measures. The use of the storage battery can ensure that in an emergency, the power system is not affected by external power failure or interruption, and can trigger the alarm unit 8 in time to remind the operator or ground personnel.

[0052] Alternatively, if Figure 3 As shown, in other embodiments, a wireless transmission module can be installed in the ladder body 3 of the device, and the wireless transmission module is electrically connected to the controller, and the controller is connected to the monitoring terminal of the remote supervisor through the wireless transmission module. The camera 6 can also wirelessly transmit the monitoring screen to the monitoring terminal through the controller for remote monitoring, data storage and backtracking. The supervisor can view the video data of the ladder body and the work site anytime and anywhere through a mobile device or computer, and can realize real-time monitoring of the on-site operation. Once a safety risk is found, it can be stopped in time or corresponding adjustments can be made. In a high-risk working environment, remote monitoring can increase the speed of emergency response, and it is also convenient for post-investigation and responsibility tracing.

[0053] Furthermore, when the pressure sensor 4 detects that the ground personnel are holding the escalator with one hand or there is no one on the escalator, and issues an alarm through the alarm unit 8, the alarm information is also remotely sent to the inspector, who conducts remote video viewing and takes corresponding work to prevent this situation. The monitoring data of the pressure sensor 4 can also provide support for later data analysis. When an accident occurs or an alarm is issued, the cause of the accident can be found out through data backtracking, whether it is a safety problem caused by the failure of the ground personnel to hold the escalator in time, which can improve the safety management level of the workplace. Moreover, through the long-term accumulation and analysis of the data of the pressure sensor 4, potential safety hazards can be discovered and possible risks can be warned in advance.

[0054] The safety ladder climbing device for preventing unmanned escalators from working at heights provided in this solution uses components such as pressure sensors 4, proximity sensors 1, cameras 6, warning lights, and speakers to build an efficient and flexible safety protection system, which can not only actively remind ground personnel to use the escalator during work, but also monitor the escalator status of ground personnel in real time, and has remote monitoring and independent power supply capabilities, greatly improving the safety and efficiency of high-altitude operations. Moreover, this device not only improves the safety of high-altitude operations, but also optimizes the operation process.

[0055] The above is only an optional embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0056] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being only exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0058] In the description of this scheme, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing this scheme and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation.
