Description

Technical Field

[0001] This invention is a fall-prevention ladder for climbing, belonging to the field of construction ladder technology. Background Technology

[0002] Construction ladders are tools used in construction for moving workers up and down between different floors or at different heights. They typically consist of a set of parallel ladders and horizontal connectors, allowing workers to climb up and down to complete their tasks.

[0003] Existing climbing ladders are generally made of metal materials (such as aluminum alloy or steel). They have a sturdy structure and stable support, capable of withstanding significant weight and pressure. In addition, they are equipped with additional facilities such as handrails and safety foot pads to provide extra support and convenience.

[0004] However, existing aerial ladders, being vertical, require workers to frequently climb up and down to move around. Furthermore, the lack of safety harnesses means workers lack effective protective measures when using them. The risk of a fall increases significantly, especially if a worker slips or loses their balance, potentially leading to serious injury or even death. Therefore, while aerial ladders are a common tool in construction, they still pose certain safety hazards. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a fall-proof climbing ladder to solve the problem that in the existing technology, when working with ladders in construction, safety belts are usually not installed because climbing up and down is required, which is dangerous if one falls.

[0006] To solve the above problems, the present invention is achieved through the following technical solution: a fall-prevention climbing ladder, comprising: a ladder frame, and a set of hooks symmetrically arranged above the ladder frame;

[0007] A fall protection mechanism is provided on one side of the ladder frame. The fall protection mechanism includes a fall arrestor fixedly installed on one side of the ladder frame, a safety rope installed inside the fall arrestor, and a safety ring fixed at the end of the safety rope.

[0008] A traction mechanism is provided on one side of the ladder frame, and the traction mechanism is located on the same side and below the fall arrestor. The traction mechanism includes a traction motor fixedly installed on one side of the ladder frame, a traction rope installed inside the traction motor, and the traction rope is fixedly connected to a safety ring.

[0009] The control module is installed inside the ladder frame. The control module includes a power module installed inside the ladder frame and a motor wireless receiver module electrically connected to the power module. The input end of the traction motor is connected to the output end of the motor wireless receiver module.

[0010] The traction motor is driven by the wireless receiving module of the motor, which controls the traction rope to drive the safety rope and fall arrestor down.

[0011] As a further improvement, a pressure sensor is embedded inside the hook, the output end of the pressure sensor is electrically connected to the input end of the traction motor, and the input end of the pressure sensor is electrically connected to the power module. A wear-resistant sheet is attached to the outer side of the pressure sensor, and the edge of the wear-resistant sheet is embedded inside the hook.

[0012] As a further improvement, the fall arrest mechanism also includes a control housing, which is fixedly installed on the top right end of the ladder frame. A set of mounting components is fixedly installed at the top of the inside of the control housing. A top block is welded below the mounting components. An alarm device is embedded and fixedly installed at the middle of the upper end of the top block. The top block is fixedly connected to the fall arrester.

[0013] As a further improvement, the alarm device includes a trigger sensor fixed on the top block and a sound-emitting module electrically connected to the control module. The receiving end of the trigger sensor is electrically connected to the input end of the control module, and the input end of the sound-emitting module is connected to the output end of the control module.

[0014] As a further improvement, the trigger sensor is an electromagnetic vibration sensor, and the trigger range is 0.5g to 0.8g.

[0015] As a further improvement, the alarm device also includes a positioning module and a wireless transmission module, which are electrically connected to the control module. The output terminal of the positioning module is connected to the input terminal of the wireless transmission module, and the wireless transmission module is communicatively connected to an external terminal.

[0016] As a further improvement, the control module also includes control buttons embedded on one side of the ladder frame, which are electrically connected to the traction motor.

[0017] As a further improvement, the mounting component includes a hollow fixing rod fixedly mounted inside the top of the control housing. A shock-absorbing spring is welded to the top of the hollow fixing rod, and a connecting rod is welded to the lower end of the shock-absorbing spring. The lower end of the connecting rod is slidably mounted inside the hollow fixing rod, and the connecting rod is welded to the upper end of the top block.

[0018] As a further improvement, the mounting component also includes a crossbar that extends laterally through the connecting rod, with buffers fixedly mounted at both ends of the crossbar, and the top of the buffers being fixedly connected to the top of the control housing.

[0019] As a further improvement, the alarm device also includes a power-on testing module, which is electrically connected to the wireless transmission module and the control module.

[0020] The beneficial effects of this invention are:

[0021] This invention allows the ladder frame to be hung on the steel frame of a construction scaffold by installing hooks on the ladder frame. When construction workers are below the ladder frame, they can control the traction motor to connect to the power supply and start via an external mobile phone through a motor wireless receiving module. The start-up motor winds and winds the traction rope, thereby conveying the safety ring from top to bottom. When the safety ring descends to a preset range, the traction motor is controlled to disconnect the power supply, thus making it convenient for construction workers below the ladder frame to fasten the safety ring with a safety buckle.

[0022] By installing fall arrestors on the side of the ladder, with the safety rope and safety ring fixed to the fall arrestor, if a worker falls into a hole or loses balance while climbing the ladder, the instantaneous tension will trigger the fall arrestor, thus controlling the worker's slow descent, reducing danger and improving construction safety.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] In order to address the aforementioned problems with existing vertical ladders, which require workers to frequently climb up and down, and which lack safety harnesses, thus providing no effective protection for workers, this invention discloses the following technical solution:

[0041] Reference Figure 1-6 As shown, a fall-prevention climbing ladder includes: a ladder frame 1 and a set of hooks 11 symmetrically arranged above the ladder frame 1;

[0042] A fall protection mechanism 2 is provided on one side of the ladder frame 1. The fall protection mechanism 2 includes a fall arrestor 21 fixedly installed on one side of the ladder frame 1, a safety rope 22 installed inside the fall arrestor 21, and a safety ring 23 fixed at the end of the safety rope 22.

[0043] A traction mechanism 3 is provided on one side of the ladder frame 1. The traction mechanism 3 is located on the same side and below the fall arrestor 21. The traction mechanism 3 includes a traction motor 31 fixedly installed on one side of the ladder frame 1, and a traction rope 32 installed inside the traction motor 31. The traction rope 32 is fixedly connected to the safety ring 23.

[0044] The control module 4 is installed inside the ladder frame 1. The control module 4 includes a power module 41 installed inside the ladder frame 1 and a motor wireless receiver module 42 electrically connected to the power module 41. The input end of the traction motor 31 is connected to the output end of the motor wireless receiver module 42.

[0045] The traction motor 31 is driven by the wireless receiving module 42, which controls the traction rope 32 to drive the safety rope 22 and the fall arrestor 21 to descend.

[0046] Handles 5 are symmetrically welded on both sides of the ladder frame 1, and the ladder frame 1 can be moved by means of the handles 5.

[0047] By setting hooks 11 on the ladder frame 1, the ladder frame 1 can be hung on the steel frame of the construction scaffold. When the construction workers are below the ladder frame 1, they can control the traction motor 31 to connect to the power supply and start it through the motor wireless receiving module 42 via an external mobile phone. The start of the motor will wind and rewind the traction rope 32, thereby conveying the safety ring 23 from top to bottom. When the safety ring 23 descends to the preset range, the traction motor 31 will be controlled to disconnect the power supply, so that the construction workers below the ladder frame 1 can fasten the safety ring 23 with the safety buckle.

[0048] By installing a fall arrestor 21 on the side of the ladder 1, and fixing the safety rope 22 on the fall arrestor 21 to the safety ring 23, if a construction worker falls into a hole or loses balance while climbing on the ladder 1, the instantaneous pulling force will trigger the fall arrestor 21, thereby controlling the construction worker to fall slowly, thus reducing the danger and improving construction safety.

[0049] In this embodiment, the fall arrestor 21 is a self-locking type: this fall arrestor 21 has a built-in automatic reel-in mechanism that can automatically adjust according to the user's movement. When the user is ascending, the fall arrestor 21 will automatically tighten to maintain a safe distance. When the user is descending, the fall arrestor 21 will loosen slightly to allow the user to move freely.

[0050] The fall arrest mechanism 2 also includes a control housing 24, which is fixedly installed on the top right end of the ladder frame 1. A set of mounting components 25 is fixedly installed inside the top of the control housing 24. A top block 26 is welded below the mounting components 25. An alarm device 27 is embedded and fixedly installed in the middle of the upper end of the top block 26. The top block 26 is fixedly connected to the fall arrester 21.

[0051] To prevent construction workers from falling due to fainting, shock, dizziness, or other physical reasons while working alone, which could make self-rescue difficult and leave no one else nearby, an alarm device 27 is installed. The alarm device 27 includes a trigger sensor 271 fixed to the top block 26 and a sound-emitting module 272 electrically connected to the control module 4. The receiving end of the trigger sensor 271 is electrically connected to the input end of the control module 4, and the input end of the sound-emitting module 272 is connected to the output end of the control module 4. Since the trigger sensor 271 is closely integrated with the fall arrestor 21, when the trigger sensor 271 detects that the fall arrestor 21 has been triggered, it sends a trigger signal to the control module 4 through its output end. The control module 4 then powers on the sound-emitting module 272, causing it to emit an alarm sound, alerting other nearby construction workers to provide timely assistance.

[0052] In this embodiment, the sound module 272 is a recording speaker that records preset alarms.

[0053] In this embodiment, the trigger sensor 271 is an electromagnetic vibration sensor, and the trigger range is 0.5g to 0.8g. If the trigger condition of the electromagnetic vibration sensor is less than 0.5g, it will be overly sensitive, greatly increasing the probability of false triggering during normal operation; conversely, if the trigger condition is greater than 0.8g, it will be too sluggish, greatly increasing the probability that the fall arrestor 21 will trigger while the electromagnetic vibration sensor fails to do so. Therefore, the trigger range of the electromagnetic vibration sensor is set to 0.5g to 0.8g, and its trigger condition is preferably 0.6g. Here, g represents acceleration.

[0054] To further avoid situations where construction sites are too remote and construction personnel are scattered, the alarm device 27 also includes a positioning module 273 and a wireless transmission module 274. The positioning module 273 and the wireless transmission module 274 are electrically connected to the control module 4. The output of the positioning module 273 is connected to the input of the wireless transmission module 274, and the wireless transmission module 274 is communicatively connected to an external terminal. During use, when the trigger sensor 271 detects that the fall arrestor 21 has been triggered, it sends a trigger signal to the control module 4 through its output. The control module 4 then connects the positioning module 273 and the wireless transmission module 274, connecting them to a power source. The wireless transmission module 274 can obtain the positioning information from the positioning module 273 and continuously transmit it to the external terminal, allowing the external terminal to immediately locate the accident and notify nearby construction personnel for emergency rescue.

[0055] To further improve safety and construction safety, a pressure sensor 12 is embedded inside the hook of the hook 11. The output of the pressure sensor 12 is electrically connected to the input of the traction motor 31, and the input of the pressure sensor 12 is electrically connected to the power module 41. When the ladder frame 1 is hung on the steel frame of the building construction scaffold, the contact between the steel frame and the hook 11 will trigger the pressure sensor 12, thereby powering on the alarm device 27 and keeping it in standby mode.

[0056] To improve safety performance, the present invention further provides a method for verifying the safe transmission of signals after the trigger sensor 271 is triggered, through a linkage mechanism with the pressure sensor 12. Specifically, this is achieved by setting up a power-on verification module 275, which is electrically connected to the wireless transmission module 274 and the control module 4.

[0057] The power-on test module 275 is connected to the input of the trigger sensor 271 and the output of the control module 4. The output of the power-on test module 275 is connected to the input of the wireless transmission module 274. When the pressure sensor 12 is triggered, the control module 4 turns on the power to the trigger sensor 271. At the moment of power-on, the power-on test module 275 detects that its voltage matches the voltage of the control module 4 and sends a normal signal to the external terminal through the wireless transmission module 274. This signal indicates that the device is in use and triggers the sensor 271 to use normally.

[0058] If only the voltage of the control module 4 is detected, but the voltage of the power-on verification module 275 is not detected, an abnormal signal is sent to the external terminal through the wireless transmission module 274. This signal indicates that the device is in use, but the trigger sensor 271 is not activated and powered on.

[0059] The advantage of this setting is that it prevents the trigger sensor 271 from being inactive and thus failing to detect danger, thereby enabling timely warnings.

[0060] In this embodiment, the power-on testing module 275 employs a voltage sensor: a voltage sensor is a sensor device specifically designed for measuring voltage. It can convert voltage signals into readable electrical signal outputs, such as analog voltage or digital signals.

[0061] To extend the service life of the pressure sensor 12, a wear-resistant sheet 13 is attached to the outer surface of the pressure sensor 12, and the edge of the wear-resistant sheet 13 is embedded inside the hook of the hook 11. This prevents the pressure sensor 12 from directly contacting the steel frame, thus protecting it. In this embodiment, the wear-resistant sheet 13 is made of polyurethane rubber: polyurethane rubber has excellent wear resistance and fatigue resistance, and can maintain a long service life even under high load and high friction conditions.

[0062] To prevent insufficient mobile signal from preventing the motor from starting, a second control system is provided. The control module 4 also includes a control button 43 embedded on one side of the ladder frame 1, which is electrically connected to the traction motor 31. In use, the traction motor 31 can be directly started by controlling the control button 43 located at the lower part of the ladder frame 1.

[0063] Because the instantaneous pulling force when the fall arrester 21 is triggered is relatively large, in order to improve the stability of the fall arrester 21 and match the triggering conditions of the electromagnetic vibration sensor, the mounting component 25 includes a hollow fixing rod 251 fixedly mounted inside the top of the control housing 24. A shock-absorbing spring 252 is welded to the top of the hollow fixing rod 251, and a connecting rod 253 is welded to the lower end of the shock-absorbing spring 252. The lower end of the connecting rod 253 is slidably mounted inside the hollow fixing rod 251, and the connecting rod 253 is welded to the upper end of the top block 26. The mounting component 25 also includes a crossbar 254 that runs horizontally through the connecting rod 253. Buffers 255 are fixedly mounted at both ends of the crossbar 254, and the top of the buffers 255 is fixedly connected to the top of the control housing 24. When the fall arrestor 21 is triggered, the whole system experiences a brief high-frequency vibration. The damping spring 252 is set to enhance the instantaneous kinetic energy of the fall arrestor 21 during triggering, thereby better triggering the electromagnetic vibration sensor. The buffer 255 is set to promptly unload and buffer the high-frequency vibration after the fall arrestor 21 is triggered.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
