Description

Technical Field

[0001] The invention relates to the technical field of building construction protection, and in particular to a high-altitude falling safety protection device for a construction site. Background Art

[0002] In the construction industry, working at heights is an inevitable process, such as exterior wall construction, steel structure installation, tower crane, construction elevator and other equipment installation and maintenance. Although existing safety regulations require workers to wear safety belts, safety ropes and other protective equipment, in extreme cases, such as failure of the safety belt fixing point, workers losing balance, etc., there is still a possibility of falling from heights, which seriously threatens the life safety of workers. Therefore, wearing safety protection devices is used for protection;

[0003] The self-inflation principle is now more commonly used; a pressure sensor and a gas generator (such as a compressed gas tank or a small chemical gas generator) are built into the vest. When the sensor detects a sudden free fall, the gas generator is immediately triggered, causing the device to automatically inflate in a very short time (such as within 0.5 seconds), forming a protective airbag surrounding the wearer's body, effectively dispersing the impact of the fall.

[0004] However, in actual use, the gas generator at the airbag vest, although its self-inflation principle is cleverly designed and efficient, usually adopts a single gas cylinder structure, which has some potential shortcomings. Due to the lack of adequate protection facilities at the gas generator, this design makes the gas generator vulnerable to physical damage and gas cylinder damage when facing complex and changeable outdoor working environments. For example, at the construction site, sharp objects and sudden impacts may damage the gas generator, affecting its normal function and affecting the safety of subsequent construction. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the gas generator lacks adequate protection and is susceptible to physical damage in complex outdoor environments, such as sharp objects and impacts at the construction site, which may cause damage to the gas cylinder and affect its function and construction safety.

[0006] The invention provides a high-rise fall safety protection device for construction sites, comprising an airbag vest, wherein a pressure controller is cleverly added to the interior of the airbag vest. When a possible falling motion is detected, the pressure controller will react quickly and transmit alarm information to an alarm monitoring center in the form of an electrical signal in real time, so as to ensure that relevant personnel can be informed of the emergency situation at the first time, thereby quickly starting the emergency plan and gaining precious rescue time for the wearer; side covers are fixedly provided at the bottom of both sides of the airbag vest, a bracket is fixedly provided at the bottom end of the inner wall of the side cover, a mounting joint is fixedly provided at the top of the bracket, a gas cylinder is provided at the top of the mounting joint, a round tube is slidably provided at the middle of the gas cylinder, guard plates are provided at both sides of the round tube, a plurality of evenly spaced cylinders are fixedly provided at the top and bottom of the round tube, a support rod is slidably provided inside the cylinder, and one end of the support rod is fixedly connected to one side of the guard plate, a round plate is fixedly provided at the other end of the support rod, a support spring is fixedly provided at one side of the round plate, and a limiting component for limiting the round tube is provided at the top of the gas cylinder.

[0007] After adopting the above structure, the present invention adds a layer of round tube on the outside of the gas cylinder, and arranges a cylinder between the round tube and the two guard plates, and configures a combination of support rods, round plates and high-elastic support springs inside the cylinder, so that the gas cylinder plays a vital buffering and protection role during use. Even in the face of complex and changeable outdoor working environments, the gas cylinder can be protected from accidental impact and damage, thereby effectively maintaining the complete function and efficient operation of the gas cylinder and its airbag vest, thereby not only improving the safety of the equipment, but also providing protection for the working safety of the construction personnel, and providing indispensable safety protection for subsequent construction activities.

[0008] In a possible embodiment, the limit assembly includes a rotating cap, the rotating cap is threadedly connected to the top of the gas cylinder, a limit ring is fixedly provided at the bottom end of the rotating cap, the bottom end of the limit ring fits with the top of the round tube, an anti-skid pad is fixedly provided at the bottom end of the limit ring, and a plurality of evenly spaced anti-skid grooves are provided on the surface of the rotating cap; two positioning blocks are symmetrically fixed at the bottom of the gas cylinder, and a positioning groove that engages with the positioning block is provided at the bottom of the inner wall of the round tube; by setting up the limit assembly, the assembly is adopted to achieve accurate positioning and convenient operation of the round tube. Through the rotating cap and the anti-skid groove on it, the user only needs to rotate the rotating cap with the anti-skid groove to easily drive it to rotate; and then the limit ring is synchronously driven to move flexibly in the vertical direction, and cooperates with the anti-skid pad, the positioning block and the positioning groove to ensure the stability and safety of the round tube during use. When the user needs to remove the round tube or the external guard plate in order to replace or maintain the gas cylinder, he only needs to rotate the rotating cap in the opposite direction to easily release the locking state of the limit ring, and then he can easily remove the rotating cap and the limit ring, which greatly facilitates the disassembly of the round tube and the guard plate, thereby simplifying the operation process and improving the maintenance efficiency of the device.

[0009] In a possible embodiment, a plurality of shock absorbers are evenly spaced in the middle of the circular tube, and one end of the shock absorber is fixedly connected to one side of the corresponding guard plate; one end of the support spring is fixedly connected to one side of the inner wall of the cylinder, and the circular plate is slidably connected to the inner wall of the cylinder; a plurality of shock absorbers are added between the circular tube and the guard plate. These shock absorbers play a vital role, as they can effectively absorb and alleviate the vibration generated by the support spring during operation, thus playing a role in shock absorption. By fixing one end of the support spring on the inner wall of the cylinder, the stability of the support spring during use is ensured, and potential risks caused by shaking or misalignment are avoided; a sliding connection design is adopted between the circular plate and the cylinder, so that the circular plate is not subject to any restraint or hindrance when sliding.

[0010] In a possible embodiment, two first side pockets are symmetrically fixed at the bottom of the front of the airbag vest, and two second side pockets are symmetrically fixed at the top of the front of the airbag vest; a first zipper is fixed at the middle of the front of the airbag vest, and a second zipper is fixed at the middle of the side cover; by carefully arranging two first side pockets and two second side pockets at the bottom and top of the front of the airbag vest, the needs of construction workers for convenient carrying and instant access to daily necessary tools are met. The ingenious configuration of multiple first side pockets and second side pockets not only greatly improves the storage capacity of tools, allowing workers to classify and store various small tools or accessories in an orderly manner, but also significantly enhances work efficiency and operation flexibility; such a layout allows workers to quickly access the required tools when performing high-altitude operations or other complex construction scenes, without frequently interrupting work to search for or carry additional tool kits, thereby ensuring the continuity of operations while further improving construction safety and the smoothness of the overall operation process. In addition, the first zipper is provided to facilitate workers to wear the airbag vest, and the second zipper is provided to easily open the side cover, so as to facilitate the disassembly and replacement of the internal gas cylinder, making it more convenient to use.

[0011] In one possible implementation, airbag discharge belts are fixedly provided at the top and bottom of the back side of the airbag vest, and a discharge groove is provided on the surface of the airbag discharge belts; two airbag discharge belts are provided on the back side of the airbag vest, and a discharge groove is provided on each airbag discharge belt, ensuring that the airbag inside the vest can be discharged quickly and effectively in the event of an emergency such as falling, greatly improving the convenience and flexibility of use.
