Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction site safety protection, in particular to a high-fall safety protection device for a construction site. BACKGROUND

[0002] In the construction industry, high-altitude work is an inevitable link, such as external wall construction, steel structure installation, tower crane, construction elevator and other equipment installation and maintenance, etc. Although the existing safety specifications require workers to wear safety belts, safety ropes and other protective equipment, in extreme cases such as safety belt fixing point failure, worker imbalance, etc., high-fall accidents may still occur, seriously threatening the life safety of workers. Therefore, a safety protection device will be used to implement protection.

[0003] The currently used one is based on the self-inflating principle; a pressure sensor and a gas generator (such as a compressed gas tank or a small chemical gas generator) are built into the wearing vest. When the sensor detects sudden free-fall motion, the gas generator is triggered immediately, causing the device to automatically inflate and expand in a very short time (such as 0.5 seconds), forming a protective airbag around the wearer's body, effectively dispersing the impact force of the fall.

[0004] However, in actual use, the gas generator at the airbag vest has a clever and efficient self-inflating principle design, but the single cylinder structure used usually 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 cause the cylinder to be damaged when facing complex outdoor working environments. For example, sharp objects and sudden impacts on the construction site may cause damage to the gas generator, affecting its normal function and subsequent construction safety. SUMMARY

[0005] The technical problem to be solved by the present application is that the gas generator lacks sufficient protection and is vulnerable to physical damage in complex outdoor environments, such as sharp objects and impacts on the construction site, which may cause the cylinder to be damaged, affecting its function and construction safety.

[0006] The application provides a high-falling safety protection device for a construction site, which comprises an airbag vest, and a pressure controller is additionally arranged in the airbag vest, so that when a possible falling motion is detected, the pressure controller can rapidly respond and transmit alarm information to an alarm monitoring center in the form of an electric signal, so that relevant personnel can know the emergency in the first time, and an emergency plan can be rapidly started, so that valuable rescue time is obtained for the wearer; a side cover is fixedly arranged at the bottom of each side of the airbag vest, a support is fixedly arranged at the bottom of the inner wall of the side cover, an installation joint is fixedly arranged at the top of the support, a gas cylinder is arranged at the top of the installation joint, a circular pipe is slidably arranged in the middle of the gas cylinder, a guard plate is arranged at the two sides of the circular pipe, a plurality of circular cylinders that are uniformly spaced are fixedly arranged at the top and bottom of the circular pipe, a support rod is slidably arranged in the circular cylinder, one end of the support rod is fixedly connected with one side of the guard plate, a circular plate is fixedly arranged at the other end of the support rod, a supporting spring is fixedly arranged at one side of the circular plate, and a limiting assembly is arranged at the top of the gas cylinder to limit the circular pipe.

[0007] The application has the following advantages: by arranging a circular pipe outside the gas cylinder, and arranging a circular cylinder between the circular pipe and the two guard plates, and arranging a support rod, a circular plate and a high-elasticity supporting spring in the circular cylinder, the gas cylinder can play a very important buffering protection role in use, and can be protected from accidental impact and damage even in a complex outdoor working environment, so that the integrity and efficient operation of the gas cylinder and the airbag vest are effectively maintained, the safety of the equipment is improved, the working safety of the construction personnel is ensured, and indispensable safety protection is provided for subsequent construction activities.

[0008] In a possible implementation, the limiting assembly includes a rotating cap, which is threadedly connected to the top of the gas cylinder, and a limiting ring is fixed to the bottom end of the rotating cap, the bottom end of the limiting ring is in close contact with the top end of the circular tube, an anti-skid pad is fixed to the bottom end of the limiting ring, and a plurality of anti-skid grooves are formed in the surface of the rotating cap; two positioning blocks are symmetrically fixed to the bottom of the gas cylinder, and a positioning groove is formed in the inner wall of the circular tube and engages with the positioning blocks; the limiting assembly is provided, and the assembly is used to accurately limit the circular tube and facilitate operation. By rotating the rotating cap and the anti-skid grooves thereon, the user only needs to rotate the rotating cap with the anti-skid grooves, which can easily drive the rotation; in turn, the limiting ring is flexibly moved in the vertical direction, and the anti-skid pad, the positioning block and the positioning groove cooperate to ensure the stability and safety of the circular tube during use. When the user needs to disassemble the circular tube or the external guard plate to replace or maintain the gas cylinder, the user only needs to rotate the rotating cap in the opposite direction to easily release the locking state of the limiting ring, and then the rotating cap and the limiting ring can be conveniently removed, which greatly facilitates the disassembly of the circular tube and the guard plate, and simplifies the operation process and improves the maintenance efficiency of the device.

[0009] In a possible implementation, the middle part of the circular tube is provided with a plurality of uniformly spaced shock absorbers, and one end of each shock absorber is fixedly connected to one side of the corresponding guard plate; one end of the supporting spring is fixedly connected to one side of the inner wall of the cylinder, and the circular plate is in sliding connection with the inner wall of the cylinder; a plurality of shock absorbers are additionally provided between the circular tube and the guard plate. These shock absorbers play a crucial role, as they can effectively absorb and alleviate the vibrations generated by the supporting spring during operation, acting as shock absorbers. By fixing one end of the supporting spring to the inner wall of the cylinder, the stability of the supporting spring during use is ensured, and potential risks caused by shaking or misalignment are avoided; the sliding connection design between the circular plate and the cylinder allows the circular plate to slide without any constraints or obstructions.

[0010] In a possible implementation, the bottom of the front of the airbag vest is symmetrically provided with two first side pockets, and the top of the front of the airbag vest is symmetrically provided with two second side pockets; a first zipper is fixed on the middle of the front of the airbag vest, and a second zipper is fixed on the middle of the side cover; the two first side pockets and the two second side pockets arranged on the bottom and the top of the front of the airbag vest meet the needs of the construction workers for conveniently carrying and immediately using daily necessary tools. The ingenious arrangement of the plurality of first side pockets and the second side pockets not only greatly improves the storage capacity of the tools, but also significantly enhances the work efficiency and the operation flexibility; such an arrangement enables the workers to quickly access the required tools when performing high-altitude operations or other complex construction scenes, without the need to frequently interrupt the work to search for or carry additional tool bags, thereby ensuring the continuity of the operation, and further improving the construction safety and the smoothness of the overall operation process. The first zipper is arranged to facilitate the workers to wear the airbag vest, and the second zipper is arranged to conveniently open the side cover and facilitate the disassembly and replacement of the gas cylinder, thereby making the use more convenient.

[0011] In a possible implementation, the top of the back of the airbag vest and the bottom of the back are both fixed with airbag discharge belts, and the surface of the airbag discharge belts is provided with discharge grooves; the two airbag discharge belts are arranged on the back of the airbag vest, and the discharge grooves are arranged on each airbag discharge belt, so that the airbag inside the vest can be quickly and effectively discharged in emergency situations such as falling, thereby greatly improving the convenience and flexibility of use.
