Description

Technical Field

[0001] The present invention relates to the technical field of construction safety, and particularly relates to a safety hook assembly for assisting in alarm during high-altitude operations. Background Art

[0002] Working at heights is a common operation in industries such as construction, electricity, and communication. To ensure the safety of high-altitude operators, it is particularly important to correctly use safety belts, which can effectively avoid the risk of operators falling from heights. However, it is not uncommon for operators to wear safety belts but not hang the safety hooks when working at heights. Without an alarm reminder, workers cannot detect this in a timely manner, leading to safety accidents. In addition, the safety rope of the safety belt has a certain length, and it is rather troublesome to store the safety rope when not in use.

[0003] It can be seen that there is still room for urgent improvement in the existing safety hooks, and it is necessary to achieve the purpose of reminding to wear and install, as well as being convenient for storage after use. Therefore, a more reasonable technical solution needs to be proposed to solve the technical problems existing in the prior art. Summary of the Invention

[0004] To at least overcome one of the above-mentioned defects, the present invention proposes a safety hook assembly for assisting in alarm during high-altitude operations. By adjusting and improving the structure of the hook, it can be used in cooperation with a safety belt, remind operators to hang the safety hook according to the actual situation of use, improve the safety of use, and be able to store the safety hook during storage, thereby improving the safety of use and the convenience of storage.

[0005] To achieve the above object, the safety hook disclosed by the present invention can adopt the following technical solutions:

[0006] A safety hook assembly for assisting in alarm during high-altitude operations includes a rigid main body connected in cooperation with a safety belt. An accommodation space is formed inside the rigid main body, and at least two safety hook assemblies are provided. The safety hook assembly includes a hanging rope and a hook provided on the hanging rope, and further includes a rope winder for storing the hanging rope; a detection component for detecting the hanging state of the safety hook assembly is also provided; a main control board is arranged in the accommodation space. The main control board is connected to the detection component, and is simultaneously connected to a height measurement component and an alarm component. The main control board is used for receiving and processing the detection data of the detection component and the height measurement component and controlling the start and stop of the alarm component.

[0007] For the above - disclosed safety hook assembly, multiple safety hook structures provided therein will all perform self - inspection. When it is hooked to a scaffolding, the connection detection component can detect a safety signal. When the safety hook structure is not connected to the scaffolding, the connection detection component cannot detect a safety signal. In this case, according to the height data measured by the height measurement component, if the preset height value has been reached, the main control board controls the alarm component to give an alarm until the connection detection component detects a safety signal.

[0008] Furthermore, there are various ways to achieve connection detection and it is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: a detection wire is provided on the hanging rope, and the detection wire is connected to the hook. When the hook is hooked to the construction scaffolding, the detection wire is grounded, so that the detection component forms a circuit and generates a safety detection signal. When such a scheme is adopted, the detection wire can be arranged inside the hanging rope or on the outer surface of the hanging rope with a protective layer provided. The detection wire is connected to a power source arranged in the accommodation space. The hook is made of a metal conductive material or provided with a conductive part. When the hook is connected to the detection wire and connected to a conductive structure such as a scaffolding, the detection circuit can be conducted, and then a micro - current signal is generated and used as a safety detection signal.

[0009] Still further, in order to more accurately detect the safety detection signal after the hook is connected, an optimization is carried out here and one feasible option is proposed: a micro - current sensor is arranged in the accommodation space and connected to the detection wire. When the monitoring wire is grounded to form a path and current flows through it, the micro - current sensor generates a detection signal and sends it to the main control board.

[0010] Furthermore, in the present invention, in order to better achieve braking and improve the safety of the safety hook assembly, the safety hook assembly should have a buffering process when it is hooked and tightened, so as to avoid damage to the hanging rope or the corresponding matching structure caused by instant tightening. Specifically, an optimization is carried out here and one feasible option is proposed: a braking component is further arranged on the rigid main body. The braking component includes a hanging - rope guide arranged in the accommodation cavity and a braking member cooperating with the hanging - rope guide. A braking gap for the hanging rope to pass through is formed between the braking member and the hanging - rope guide, and the braking member is rotatably arranged in the accommodation space. When the braking member deflects towards the hanging - rope guide, it presses the hanging rope and realizes braking. An elastic reset structure is arranged on the braking member to apply a reset force to the braking member so that the rotating member deflects away from the hanging - rope guide. When such a scheme is adopted, the hanging rope is clamped by the clamping force between the braking member and the hanging - rope guide, thereby reducing the passing speed of the hanging rope; when a worker falls from a height, the hanging rope is slowly stretched and gradually clamped under the action of this braking force, avoiding instant pulling force and improving the safety of the safety hook assembly. The elastic reset structure can adopt a reset spring.

[0011] Furthermore, the combined structure of the lanyard guide and the braking member can be configured in various forms, so as to reduce the damage to the lanyard when realizing the deceleration braking of the lanyard and improve the braking effect. Here, an optimization is carried out and a feasible option is proposed: an inward concave arc-shaped braking section is provided on the lanyard guide, and a corresponding outward convex arc-shaped pressing block is provided on the braking member. When the braking member deflects towards the lanyard guide, the pressing block is clamped into the braking section and the lanyard is closely attached to the arc-shaped braking section. When such a scheme is adopted, the lanyard can bypass the lanyard guide, the braking gap and the braking member in sequence. When the lanyard is stretched upward, it drives the braking member to deflect and makes the pressing block clamped into the braking section to achieve braking; and the greater the upward pulling force of the lanyard, the greater the force driving the stopper to deflect, and the greater the clamping force of the pressing block and the braking section on the lanyard. Therefore, the braking is more flexible and the braking effect is more reliable.

[0012] Further, in order to further improve the braking performance, the cooperation structure of the braking section and the pressing block is optimized here. An optimization is carried out and a feasible option is proposed: a damping member is provided on the arc-shaped braking section and / or the arc-shaped pressing block, and a resistance force is applied to the lanyard when the lanyard passes through the damping member. When such a scheme is adopted, the damping member can adopt a damping wheel or a damping block, one is to increase the resistance to the lanyard, and the other is to increase the braking distance of the lanyard, so as to improve the braking effect.

[0013] Furthermore, in order to better guide the lanyard and ensure that the braking of the lanyard is triggered smoothly, an optimization is carried out here and a feasible option is proposed: a threading hole is provided on the braking member, and a guiding groove for guiding the lanyard is provided at the front end of the threading hole. After the lanyard fits on the surface of the lanyard guide and passes through the braking gap, it passes through the threading hole along the guiding groove and is connected to the hook. When such a scheme is adopted, due to the action of the elastic reset structure, the threading hole is vertically downward in the normal state, and the braking member is far away from the lanyard guide. When an emergency occurs, the upper safety hook and the lanyard are tightened, and the threading hole deflects upward, driving the entire braking member to deflect and reducing the braking gap between the pressing block and the braking section, so as to brake and decelerate the lanyard. Finally, after decelerating and stopping, safety tightening is achieved. In this way, it can be ensured that the lanyard can accurately trigger the braking action and can provide sufficient braking force according to the change of the pulling force.

[0014] Further, in the present invention, the height measurement component is used to detect the height where the operator is currently located. When the preset height value is reached, the safety hook component needs to be worn, and an alarm is triggered to remind the operator. Here, an optimization is carried out and one feasible option is proposed: the height measurement component includes an infrared processor, an infrared emitter, and an infrared receiver. Both the infrared emitter and the infrared receiver are vertically downward, and the infrared emitter emits an infrared signal, which is reflected and then received by the infrared receiver. The infrared processor calculates the current height of the hook component. When such a scheme is adopted, the infrared emitter and the infrared receiver detect the current height of the rigid body according to the transmitted signal and the received signal, so as to obtain the current height of the operator. In some other feasible schemes, in addition to using infrared ranging technology, other schemes can also be used for height measurement, such as ultrasonic ranging, laser ranging, etc.

[0015] Further, in the present invention, the alarm component is used to remind the operator to wear the safety hook in time. A variety of feasible schemes can be adopted, and it is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: the alarm component includes an alarm light and an alarm buzzer. When such a scheme is adopted, as long as the detected height value received by the main control board reaches the preset height and at the same time the micro-current signal indicating that the safety hook has been hooked is not detected, the alarm component is controlled to give an alarm reminder.

[0016] Further, in the present invention, in order to further improve the safety performance, an optimization is carried out on the rigid body and one feasible option is proposed as follows: a self-locking hanging rope is also provided on the rigid body, and a self-locking hook is connected to the end of the self-locking hanging rope. When such a scheme is adopted, the self-locking hook and the safety hook structure jointly perform safety hanging.

[0017] Compared with the prior art, some beneficial effects of the disclosed technical solution of the present invention include:

[0018] By setting the safety hook structure, the present invention detects during high-altitude operations and gives an alarm reminder for the behavior of not hooking the safety hook. After the high-altitude operation is completed, the hanging rope can be retracted through the rope winding device for storage, improving the convenience of using the safety hook component.

[0027] In view of the situation in the prior art that the safety hook does not have a safety reminder and is not convenient to store after use, resulting in inconvenient use, the following embodiments are optimized and overcome the defects existing in the prior art.

[0028] Embodiment

[0029] As Figures 1 to 4 shown, this embodiment provides a safety hook assembly for high-altitude operation auxiliary alarm, which includes a rigid body 1 connected to the safety belt in a cooperative manner. An accommodation space is formed inside the rigid body 1 and at least two safety hook 503 assemblies are provided. The safety hook 503 assembly includes a lanyard 502 and a hook 503 provided on the lanyard 502, and further includes a rope winder 501 for storing the lanyard 502; a detection component for detecting the hanging state of the safety hook 503 assembly is also provided; a main control board 10 is provided in the accommodation space. The main control board 10 is connected to the detection component and is also connected to a height measurement component 7 and an alarm component at the same time. The main control board 10 is used to receive and process the detection data of the detection component and the height measurement component 7 and control the start and stop of the alarm component.

[0030] For the safety hook 503 component disclosed in this embodiment, multiple safety hook structures 5 provided thereon will perform self-checks. When it is hooked to the scaffolding, the connection detection component can detect a safety signal. When the safety hook structure 5 is not connected to the scaffolding, the connection detection component cannot detect a safety signal. In this case, according to the height data measured by the height measurement component 7, if the preset height value has been reached, the main control board 10 controls the alarm component to give an alarm until the connection detection component detects a safety signal.

[0031] There are various ways to achieve connection detection and it is not uniquely limited. This embodiment is optimized and one feasible option is adopted: a detection wire is provided on the hanging rope 502, and the detection wire is connected to the hook 503. When the hook 503 is hooked to the construction scaffolding, the detection wire is grounded, so that the detection component forms a loop and generates a safety detection signal. When adopting such a scheme, the detection wire can be arranged inside the hanging rope 502 or on the outer surface of the hanging rope 502 with a protective layer provided. The detection wire is connected to a power source arranged in the accommodation space. The hook 503 is made of a metal conductive material or provided with a conductive part. When the hook 503 is connected to the detection wire and connected to a conductive structure such as a scaffolding, the detection circuit can be conducted, and then a micro-current signal is generated and used as a safety detection signal.

[0032] In order to more accurately detect the safety detection signal after the hook 503 is connected, this embodiment is optimized and one feasible option is adopted: a micro-current sensor 9 is arranged in the accommodation space and connected to the detection wire. When a current flows through the detection wire after it is grounded to form a path, the micro-current sensor 9 generates a detection signal and sends it to the main control board 10.

[0033] In this embodiment, in order to better achieve braking and improve the safety of the safety hook 503 assembly, a buffering process should be provided when the safety hook 503 assembly is hooked and tightened, so as to avoid damage to the hanging rope 502 or the corresponding mating structure caused by instantaneous tightening. Specifically, this embodiment is optimized and one feasible option is adopted: a braking assembly 6 is further provided on the rigid body 1. The braking assembly 6 includes a hanging rope guide 601 disposed in the accommodation cavity and a braking member 602 cooperating with the hanging rope guide 601. A braking gap for the hanging rope 502 to pass through is formed between the braking member 602 and the hanging rope guide 601, and the braking member 602 is rotatably disposed in the accommodation space. When the braking member 602 deflects towards the hanging rope guide 601, it presses the hanging rope 502 to achieve braking. An elastic reset structure is provided on the braking member 602 to apply a reset force to the braking member 602 to deflect the rotating member away from the hanging rope guide 601. When such a solution is adopted, the hanging rope 502 is clamped by the clamping force between the braking member 602 and the hanging rope guide 601, thereby reducing the passing speed of the hanging rope 502; when the worker falls from a height, the hanging rope 502 is slowly stretched and gradually clamped under the action of this braking force, avoiding instantaneous tension and improving the safety of the safety hook 503 assembly. The elastic reset structure can adopt a reset spring.

[0034] The combined structure of the hanging rope guide 601 and the braking member 602 can be constructed in various forms, so as to reduce the damage to the hanging rope 502 when realizing the deceleration braking of the hanging rope 502 and improve the braking effect. This embodiment is optimized and one feasible option is adopted: an inwardly concave arc-shaped braking section 601a is provided on the hanging rope guide 601, and a corresponding outwardly convex arc-shaped abutting block 602a is provided on the braking member 602. When the braking member 602 deflects towards the hanging rope guide 601, the abutting block is inserted into the braking section and the hanging rope 502 is closely attached to the arc-shaped braking section 601a. When such a solution is adopted, the hanging rope 502 can bypass the hanging rope guide 601, the braking gap and the braking member 602 in sequence. When the hanging rope 502 is stretched upward, it drives the braking member 602 to deflect and the abutting block is inserted into the braking section to achieve braking; and the greater the upward pulling force of the hanging rope 502, the greater the force driving the stop member to deflect, and the greater the clamping force of the abutting block and the braking section on the hanging rope 502. Therefore, the braking is more flexible and the braking effect is more reliable.

[0035] Preferably, the arc-shaped braking surfaces of the arc-shaped braking section 601a and the arc-shaped abutting block 602a can be formed by a combination of a circular arc, an elliptical arc or a multi-segment variable-diameter arc.

[0036] In order to further improve the braking performance, the matching structure of the braking section and the abutting block is optimized here. In this embodiment, one feasible option is optimized and adopted: a damping member is provided on the arc-shaped braking section 601a and / or the arc-shaped abutting block 602a. When the hanging rope 502 passes through the damping member, a resistance force is applied to it. When such a solution is adopted, the damping member can be a damping wheel or a damping block. One is to increase the resistance to the hanging rope 502, and the other is to increase the braking distance of the hanging rope 502, thereby improving the braking effect.

[0037] In order to better guide the hanging rope 502 and ensure that the braking of the hanging rope 502 is triggered smoothly, one feasible option is optimized and adopted in this embodiment: a threading hole 602b is provided on the braking member 602, and a guiding groove for guiding the hanging rope 502 is provided at the front end of the threading hole 602b. After the hanging rope 502 fits on the surface of the hanging rope guiding member 601 and passes through the braking gap, it passes through the threading hole 602b along the guiding groove and is connected to the hook 503. When such a solution is adopted, due to the action of the elastic reset structure, the threading hole 602b is vertically downward under normal conditions, and the braking member 602 is far away from the hanging rope guiding member 601. When an emergency occurs, the upper safety hook 503 and the hanging rope 502 are tightened, causing the threading hole 602b to deflect upward, driving the entire braking member 602 to deflect and reducing the braking gap between the abutting block and the braking section, thereby braking and decelerating the hanging rope 502. Finally, after decelerating and stopping, safe tightening is achieved. In this way, it can be ensured that the hanging rope 502 can accurately trigger the braking action and can provide sufficient braking force corresponding to the change in the pulling force.

[0038] In this embodiment, the height measurement assembly 7 is used to detect the current height of the operator. When the preset height value is reached, the safety hook 503 assembly needs to be worn, and an alarm is triggered to remind the operator. One feasible option is optimized and adopted in this embodiment: the height measurement assembly 7 includes an infrared processor 8, an infrared emitter, and an infrared receiver. The infrared emitter and the infrared receiver are both vertically downward, and the infrared emitter emits an infrared signal, which is reflected and received by the infrared receiver, and the current height of the hook 503 assembly is calculated by the infrared processor 8. When such a solution is adopted, the infrared emitter and the infrared receiver detect the current height of the rigid body 1 according to the transmitted signal and the received signal, so as to obtain the current height of the operator. In some other feasible solutions, in addition to using infrared ranging technology, other solutions can also be adopted for height measurement: for example, ultrasonic ranging, laser ranging, etc.

[0039] In this embodiment, the alarm component is used to remind the operator to wear the safety hook 503 in time. A variety of feasible solutions can be adopted, and it is not uniquely limited. This embodiment is optimized and one of the feasible options is adopted: the alarm component includes an alarm lamp 3 and an alarm buzzer 2. When adopting such a solution, as long as the detected height value received by the main control board 10 reaches the preset height and at the same time the micro-current signal indicating that the safety hook 503 has been hooked is not detected, the alarm component is controlled to give an alarm reminder.

[0040] In this embodiment, in order to further improve the safety performance, the rigid main body 1 is optimized and one of the following feasible options is adopted: a self-locking hanging rope 4 is further provided on the rigid main body 1, and a self-locking hook is connected to the end of the self-locking hanging rope 4. When adopting such a solution, the self-locking hook 503 and the safety hook structure 5 jointly perform safety hooking.

[0041] The above are the implementation manners listed in this embodiment. However, this embodiment is not limited to the above-mentioned optional implementation manners. Those skilled in the art can obtain many other implementation manners by arbitrarily combining the above manners. Anyone can obtain other various forms of implementation manners under the inspiration of this embodiment. The above specific implementation manners should not be construed as limiting the protection scope of this embodiment. The protection scope of this embodiment shall be defined by the claims.
