Description

Technical Field

[0001] The present invention belongs to the technical field of high-altitude working shoes, and more specifically, relates to an automatic adsorption and locking high-altitude anti-falling working shoe and an operating method. Background Art

[0002] In the process of dismantling the I-beam of the cantilever I-beam scaffolding in the construction field, the scaffolders often need to stay away from the outer wall and tie the I-beam along the width of the I-beam at high altitude. Especially in the hole parts such as the gable of the building without windows, the safety belt is hung high and low without a reliable hanging and fixing position. There are often safety accidents of falling from high altitude and getting disabled due to the illegal operation of the scaffolders (not wearing the safety belt or not fixing the safety belt). The use of this technology provides more protection and self-rescue measures for the scaffolders, and avoids the occurrence of disability accidents to the greatest extent.

[0003] In the prior art, patent CN211532917U: A labor protection shoe with a magnet improves the safety of users working in high-altitude steel environments, and can prevent the soles from adsorbing iron objects when working in non-high-altitude steel environments. However, when working at high altitudes, it affects the flexibility of construction workers and requires manual reversal of the permanent magnetic block.

[0004] In the prior art, patent CN202276886U: A new type of magnetic shoes makes it more convenient for construction workers to climb and cross beams, and effectively prevents safety accidents caused by slipping under their feet. However, the electromagnet is always working, and as the battery power decreases, the magnetism decreases, affecting the flexibility of the construction workers.

[0005] In the prior art, patent CN205180478U: A labor protection shoe with a magnet is designed with an electromagnetic device. When the user walks and the forefoot presses the sole, the pressure switch is triggered. The electromagnetic device has magnetic force and can adsorb magnetic objects. However, when a fall from a high altitude occurs, the safety of construction workers cannot be effectively guaranteed.

[0006] Therefore, at this stage, there is an urgent need for an automatic adsorption and locking high-altitude anti-fall work shoe, which can solve the shortcomings of the above patents, ensure that the device does not fall off during high-altitude operations, and protect the personal safety of construction workers when they accidentally fall from a height while dismantling cantilevered I-beams in the construction field.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 1-2As shown, the present invention provides an automatic adsorption and locking high-altitude anti-fall working shoe, including a shoe body 1, a vacuum adsorption layer 3, a shoelace cable mechanism 4, a flexible electromagnetic material layer 5, an ankle tightening mechanism 6, a power supply component 9, a displacement accelerometer 10 and a control unit. The vacuum adsorption layer 3 is arranged at the bottom of the shoe body 1, and generates adsorption force by vacuuming, so that the shoe body 1 is adsorbed on the I-beam; the shoelace cable mechanism 4 is connected to the shoelace, which can quickly tighten the shoelace and lock it at the same time with the ankle tightening mechanism 6 to prevent the work shoe from falling off; the flexible electromagnetic material layer 5 generates a strong magnetic force after being energized, so that it is adsorbed on the magnetic sensitive material at the first time; the power supply component 9 supplies power to other functional components; the displacement accelerometer 10 detects the operation acceleration value and sends the detection signal to the control unit. The control unit determines that the acceleration value exceeds the threshold value, controls the power supply component 9 to output power, vacuumizes the vacuum adsorption layer 3 to generate adsorption force, and the flexible electromagnetic material layer 5 generates a strong magnetic force, so that the shoe body 1 is adsorbed and fixed on the I-beam, and at the same time controls the shoelace cable mechanism 4 to tighten the shoelace and the ankle tightening mechanism 6 to tighten and lock, so as to prevent the construction personnel's feet from falling off the shoe body 1 and ensure that the personnel do not suffer high-rise injuries. The anti-fall work shoes of the present invention can make the shoe body 1 adsorbed and fixed on the I-beam when a fall accident occurs, thereby ensuring the safety of construction workers. At the same time, the shoe body 1 can automatically and flexibly switch the adsorption force on and off, ensuring that no adsorption force is generated in the normal working state and not affecting the flexibility of the external frame construction workers.

[0039] In the embodiment of the present invention, the shoe body 1 is made of KPU molded material, which has the advantages of being light, having good wear resistance, anti-slip properties, and resistance to bending, etc. It can ensure the safety of the construction workers' feet during high-level aerial operations without affecting the movement of the feet, thereby maintaining the flexibility of the external frame construction workers.

[0040] The bottom of the shoe body 1 is provided with a wear layer 2, which is a heat-shrinkable elastic rubber sole. It is elastic, wear-resistant, and has good anti-aging, oil resistance, and chemical corrosion resistance. It can cushion the feet of construction workers and ensure the comfort of the feet.

[0041] The vacuum adsorption layer 3 is arranged at the bottom of the wear layer 2. It is a bowl-shaped edging structure made of weather-resistant hard rubber material. Its bowl-shaped edging can effectively fit with the I-beam to form a sealed cavity. After the sealed cavity is evacuated, a large adsorption force is generated between the vacuum adsorption layer 3 and the I-beam, thereby fixing the work shoes on the I-beam to prevent construction workers from falling.

[0042] Furthermore, the vacuum adsorption layer 3 is connected to the micro vacuum pump 12 through the exhaust pipe 7. One end of the exhaust pipe 7 is connected to the vacuum adsorption layer 3, and the other end is connected to the input end of the micro vacuum pump 12. The micro vacuum pump 12 is located between the flexible electromagnetic material layer 5 and the shoe upper. The micro vacuum pump 12 is fixed on the shoe body 1, and it sucks the sealed cavity into the pump cavity and then discharges it from the output end, so that the sealed cavity is in a negative pressure state, thereby allowing the work shoe to be adsorbed on the I-beam.

[0043] The shoelace cable mechanism 4 is arranged on the shoe upper, which is connected to the shoelaces. The shoelaces are wound around the shaft by rotating the shoelace winding shaft, thereby realizing automatic tightening of the shoelaces; further, the shoelaces have a certain elasticity, and after the shoelace winding shaft is reset, they can automatically retract to their original position, thereby loosening the restraint and lock on the construction workers' feet.

[0044] The ankle locking mechanism 6 is arranged at the top of the shoe body 1, at the ankle, and includes a cable. By pulling the cable, the shoe opening at the ankle is tightened. When the anti-fall work shoes are fixed on the I-beam by adsorption, the ankle locking mechanism 6 pulls the cable to firmly fix the shoe body 1 and the foot, effectively preventing the foot of the construction worker from falling out of the shoe body 1 when the construction worker is in a tilted state. Furthermore, an elastic support structure is provided at the shoe opening, which can automatically drive the cable to return to its original state after the ankle locking mechanism 6 is reset, and will not cause discomfort to the construction worker wearing the anti-fall work shoes.

[0045] Furthermore, the shoelace cable mechanism 4 and the ankle locking mechanism 6 are respectively connected to the locking motor 11; the locking motor 11 is a micro motor, which is fixed on the shoe body 1, and a conductive belt is provided on its motor shaft, through which the shoelace cable mechanism 4 and the shoelace cable mechanism 5 are respectively connected, and power is transmitted to the shoelace cable mechanism 4 and the ankle locking mechanism 6 respectively, so that the shoelace cable mechanism 4 and the ankle locking mechanism 6 operate synchronously, and the shoe body 1 and the foot are firmly fixed, effectively preventing the foot of the construction worker from falling out of the shoe body 1 when the construction worker is in a tilted state.

[0046] The flexible electromagnetic material layer 5 is arranged on the surface of the shoe body 1. After being connected to the power supply through the electromagnet power supply cable 8, it generates a strong magnetism, thereby immediately adsorbing the shoe body 1 onto the magnetically sensitive material (I-beam) to ensure that people are not injured by falling from a height.

[0047] In order to provide power for the shoelace cable mechanism 4, the flexible electromagnetic material layer 5, the ankle locking mechanism 6 and the micro vacuum pump 12, a power supply component 9 is also fixedly provided on the shoe body 1, which includes a battery, a solar panel, a power switch button and a charging port; wherein the battery is electrically connected to the shoelace cable mechanism 4, the flexible electromagnetic material layer 5, the ankle locking mechanism 6 and the micro vacuum pump 12 respectively; the solar panel converts solar energy into electrical energy when the construction personnel are working, thereby charging the battery to keep the battery fully charged; the power switch button is electrically connected to the battery, which controls the on and off of the power output. After completing the work and taking off the anti-fall work shoes, the construction personnel can press the button to disconnect the power to avoid battery depletion; the charging port charges the battery by connecting to an external charging head.

[0048] In order to detect the falling state of the construction workers, a displacement accelerometer 10 is also provided on the shoe body 1, which is communicated with the control unit, monitors the displacement acceleration value of the construction workers in real time, and sends the acceleration value to the control unit. After detecting the abnormal acceleration displacement of the construction workers, the control unit controls the relevant functional components to lock the feet of the construction workers and fix the shoe body 1 to the I-beam.

[0049] The control unit is arranged on the shoe body 1, and is respectively connected to the power supply assembly 9, the displacement accelerometer 10, the locking motor 11 and the micro vacuum pump 12 for communication. The control unit compares the displacement acceleration value detected by the accelerometer 10 with the threshold value to determine whether the displacement acceleration value exceeds the threshold value. After determining that it exceeds the threshold value, the control unit controls the power supply assembly 9 to output power, and after the power is introduced into the flexible electromagnetic material layer 5, a strong magnetism is generated to adsorb the shoe body 1 to the magnetically sensitive material (I-beam) in the first time, and drives and controls the micro vacuum pump 12 to evacuate the sealed cavity so that the work shoe is adsorbed on the I-beam; at the same time, the locking motor 11 outputs power to tighten the shoelace cable mechanism 4 and pull the cable of the ankle locking mechanism 6 to prevent the shoe body 1 from falling off the foot of the construction worker.

[0050] Preferably, when a person falls on a fastener-type steel pipe scaffolding, since the steel pipe has a small adsorption area and cannot bear the weight of the construction workers, the sole of the shoe can be improved by adding multiple strands of symmetrical pop-up thin steel cables. The thin steel cables serve as electrical conductors, and strong magnetic buckles are set at the outer ends. The multiple strands of thin steel cables are detonated and popped out at one time to enhance the adsorption area and bearing capacity. The bottom of the thin steel cables is fixed on the flexible electromagnetic material layer, and the strong magnetic buckles at the outer ends are disorderly adsorbed on magnetically absorbable materials such as steel pipes and I-beams.

[0051] Preferably, the shoe body 1 is also provided with an audible and visual alarm, which is communicatively connected with the control unit. When an abnormal operation displacement amplitude occurs, the audible and visual alarm emits an audible and visual alarm to promptly remind rescue personnel to provide assistance.

[0052] When the anti-fall work shoes of this aspect are used for operation, the construction personnel check whether the power supply, adsorption, locking and other functions of the work shoes are normal; after confirming that they are normal, they put on the work shoes and enter the construction site; when the scaffolding workers in the construction field dismantle the external frame I-beam and the soles of their feet are empty, the control unit determines that the displacement acceleration value detected by the accelerometer 10 exceeds the threshold value, and controls the power supply component 9 to output power; the flexible electromagnetic material layer 5 generates a strong magnet after inputting current, so that it is adsorbed to the I-beam at the first time to ensure that the personnel do not suffer high-fall injuries; the micro vacuum pump 12 acts synchronously instantaneously, and evacuates the vacuum adsorption layer 3 and the I-beam to form a sealed cavity through the exhaust pipe 7, so that the sealed cavity is in a negative pressure state, thereby making the operation The shoe is adsorbed on the I-beam; the locking motor 11 outputs power to synchronously drive the shoelace cable mechanism 4 and the ankle locking mechanism, so that the shoelace cable mechanism 4 automatically tightens the shoelaces, and the ankle locking mechanism 6 pulls the cable, thereby restraining and locking the construction worker's feet to prevent the construction worker's feet from falling out of the shoe body 1; after the construction worker is rescued, the rescuer cuts off the power supply and restarts the anti-fall work shoes, and the control unit controls the power supply component 9 to cut off the power to the flexible electromagnetic material layer 5 and the micro vacuum pump 12, releases the adsorption of the I-beam, and at the same time controls the locking motor 11 to rotate, so that the shoelace cable mechanism 4 and the ankle locking mechanism 6 are reset, and the shoelaces and cables are restored to their original state, avoiding discomfort to the construction workers wearing the anti-fall work shoes.

[0053] The anti-fall work shoes of the present invention have automatic adsorption and locking functions. When a fall accident occurs, the vacuum adsorption layer 3 and the flexible electromagnetic material layer 5 can be used to quickly adsorb and fix the shoe body on the I-beam. At the same time, the shoelaces are automatically tightened through the shoelace cable mechanism 4, so that the ankle locking mechanism 6 pulls the cable, thereby restraining and locking the feet of the construction workers to prevent the feet of the construction workers from falling out of the shoe body 1, thereby ensuring the safety of the construction workers.

[0054] The anti-falling work shoes of the present invention can automatically and flexibly switch the adsorption force on and off under normal working conditions without affecting the flexibility of construction workers; at the same time, they can be quickly locked when needed to ensure that the work shoes will not fall off, thereby improving the safety of users working in high-altitude steel environments, and still not affecting the flexibility of operators when working in non-high-altitude steel environments.

[0055] The anti-fall work shoes of the present invention have a shoe body 1 made of KPU molded material, which is light and has good wear resistance, anti-slip properties, and bending resistance. A wear layer is provided on the bottom to provide cushioning and comfort. The ankle locking mechanism is designed with wearing comfort in mind, and other functional components are designed with micro-structures, which minimize the overall weight while ensuring that the functions meet the requirements, and will not cause discomfort to construction workers.

[0056] The anti-fall work shoes of the present invention have a displacement accelerometer 10 and a control unit built into the shoe body, which can monitor the displacement acceleration value of the construction workers in real time and automatically trigger the locking mechanism when abnormal acceleration displacement is detected, thereby realizing intelligent fall protection.

[0057] like Figure 4 As shown, in another embodiment of the present invention, the anti-fall work shoe also includes a caliper 13, which is provided with four groups, respectively arranged at the front and rear ends and both sides of the shoe body 1; the caliper 13 includes a caliper body 131, a caliper tongue 132 and a caliper shaft 133, the caliper tongue 132 is fixedly arranged on the shoe body 1, and its bottom is located on the outside of the shoe body 1 and is flush with the sole; the upper end of the caliper body 131 is hinged to the caliper tongue 132 through the caliper shaft 133, and can rotate around the caliper shaft 133; further, the caliper body 131 is connected to the drive motor through a wire rope, and the drive motor is communicatively connected to the control unit. Under the control of the control unit, the drive motor rotates, and the wire rope is quickly released, so that the caliper body 131 falls freely and contacts the bottom of the upper wing plate of the I-beam, and at the same time cooperates with the caliper tongue 132 to clamp and lock the upper wing plate of the I-beam to prevent the operator from falling; a locking spring is also provided between the caliper body 131 and the caliper tongue 132 to prevent the clamping from shaking and detaching. Preferably, the pliers body 131 is also provided with a toothed anti-slip plate 135, and the pliers tongue 132 is provided with a pliers tongue tooth portion 134, which increases the pressure by reducing the contact area with both sides of the upper wing plate of the I-beam, making the pliers 13 clamp more firmly, thereby effectively ensuring the safety of construction workers.

[0058] like Figure 5 As shown, the present invention also provides an operation method for automatically adsorbing and locking high-altitude anti-falling work shoes, comprising the following steps:

[0059] S100: Construction workers check whether the power supply, adsorption, locking and other functions of the work shoes are normal;

[0060] S200: After confirming that everything is normal, put on work shoes and enter the construction site;

[0061] S300: When the scaffolding workers in the construction field dismantle the I-beam of the external frame and the bottom of the foot is empty, the control unit determines that the displacement acceleration value detected by the displacement accelerometer 10 exceeds the threshold value, and controls the power supply component 9 to output power;

[0062] S400: After the current is input into the flexible electromagnetic material layer 5, a strong magnet is generated, so that it is immediately adsorbed onto the I-beam;

[0063] S500: The micro vacuum pump 12 is synchronously actuated instantaneously to evacuate the sealed cavity formed by the vacuum adsorption layer 3 and the I-beam through the exhaust pipe 7, so that the sealed cavity is in a negative pressure state, thereby making the work shoe adsorbed on the I-beam;

[0065] S700: After the construction workers are rescued, the rescuers cut off the power supply and restart the anti-fall work shoes;

[0066] S800: The control unit controls the power supply assembly 9 to cut off the power to the flexible electromagnetic material layer 5 and the micro vacuum pump 12, releases the adsorption of the I-beam, and controls the locking motor 11 to rotate, so that the shoelace cable mechanism 4 and the ankle locking mechanism 6 are reset, so that the shoelaces and cables return to their original state.
