Description

The invention relates to protective devices of the body from falling from a person’s height and can be used in the field of labor protection to reduce injuries during high-altitude work.

According to the National Security Strategy of the Russian Federation until 2020, which designates progressive labor shortages as one of the main strategic threats to national security, a further decrease in the share of the able-bodied population in the total population is expected (Babakov A.N., Chernikova A.G. Labor protection status in Russia // Bulletin IMSIT. - 2013. - No. 3-4. - P. 21-23), (Denisov OV, Bulygin Yu.I., Ponomarev AE, Ponomareva IA, Lebedeva VV Innovative solutions shockproof protection in occupations associated with an increased risk of injury // IOP Conference Series: Earth and Environmental Science. - 2017. - V. 50. - No. 1. P. 012044). In the Russian Federation, the national standard GOST R 54934 - 2012 “Occupational Safety and Health Management Systems” is currently being implemented, however, despite this, statistics show an increase in occupational morbidity. It was revealed that the main cause of occupational pathology is unsatisfactory working conditions, the presence of jobs with harmful and dangerous working conditions (Usikova O.V. Comparative analysis of the organization of occupational health and safety systems (review of foreign experience) // Siberian Security-Spassib. - 2013. - No. 1. - P. 249-253), (Denisov O.V., Ponomareva I.A., Zimenko V.A. Protective dressing for large joints during sports // New standards for the modernization of teacher education in the formation of a healthy lifestyle and safety live lnosti: Materials of the III Regional Scientific and Practical Conference of the Southern Federal District. - 2015. - S. 90-92). A statistical analysis of injuries in the Rostov Region shows that the share of severe and fatal industrial accidents over the past twenty years has not only not decreased, but also tends to increase. In 2009 and 2011, it reached 8%, which significantly exceeds the performance of developed countries. This indicates the need for further comprehensive study of occupational injuries and the development of effective measures to improve occupational safety (Pleshko M.S., Schekina E.V., Ryabova N.V. On the problem of increasing the severity of occupational injuries in machine-building enterprises of the Rostov Region // Engineering Bulletin Don [Electronic resource]: electronic scientific - foreign journal - 2017. - No. 3. - Access mode: //www.ivdon.ru - From the screen. - State registration number 0421100096).

Among the protective equipment against human fall, successfully used in the prevention of injuries, it is necessary to note work clothes with safety belts. A well-known safety system for climbing work mainly by the cable way (invention SU No. 1773419 A1, IPC A62B35 / 00, publ. 07.11.1992), equipped with a buttock belt.

Known suit for performing work at heights with protection against falling (patent WO 128635 A1, A62B 35/00, publ. 04/26/2001). The arrangement of seat belts on it is also not optimal for working at height.

Life belts or safety belts are also widely used; similar devices for limiting the deviation of the human body during a sharp change in the speed of movement, a device for lowering from a height (patent RU No. 2509583 C1, IPC A62B 35/00, 03.20.2014, b. 8).

The closest technical solution is work clothes with safety belts (patent RU No. 2312693 C2, IPC A62B 35/00, December 20, 2007, bull. 35), located both on the inside of the clothes and on the outside, interconnected, clothes equipped with a supporting belt having a figured shape corresponding to the shape of the supporting surface in a sitting position, and additional elastic pads in the zone of maximum pressure of the buttocks, and the supporting belt is attached to the rear half of the trousers in the buttocks using belt loops located along the contour of the support print of the surface, in addition, the ends of the support belt end at the standard position of the side seam, shifted slightly forward relative to the buttocks, and have half rings, which are connected through the carabiners at the ends of the holding sling with their central carabiner to the fastening point working on a cable or rope, while the length of the retaining sling is regulated by the buckle located on it.

        The disadvantage of this work clothing is the inconvenience of performing work at height in the hovering position and the inability to control the correctness of the employee's fixation to reliable enclosing structures.

        The objective of the invention is the ease of movement in overalls when performing work above ground level, increasing the safety of work at height.

The essence of the invention lies in the fact that the overalls for work at height, which consists of work clothes with safety belts and a carabiner, including safety belts made of composite materials, characterized in that the safety belts smoothly pass into a reinforced cable containing threads made of carbon fiber , fiber and nylon threads, the side seams of the overalls contain Velcro fasteners, the reciprocal Velcro fasteners are fixed or sewn to a reinforced cable, the carabiner is equipped with a control unit with with a buzzer, LED indicators, the carabiner control unit contains a power source, an indication panel, a radio transmitter, an altimeter, a pulse transmitter and a pulse receiver, a carabiner control unit by means of radio communication signals with a stationary control unit equipped with a radio receiver, a storage device, and an information transmission device for the central console, power supply, processor, digital display panel.

The technical result of the present invention is the ease of movement in the overalls when performing work above ground level, due to the fastening of the cable with Velcro on the side seam of the overalls, and at a height due to the light weight and high flexibility of the cable. In addition, this invention is equipped with an intelligent carabiner, which gives a light and sound signal about the state of fixation of the employee at a height.

The invention is illustrated in the drawing, where

Fig.6 presents the control unit in the carabiner.

Overalls for work at heights are work clothes (overalls) 1 with reinforced zipper 2 and seat belts 3, equipped with reinforced cable 4 and made of composite materials. In this case, the reinforced cable 4 contains threads of carbon fiber 5, optical fiber 6 and nylon threads 7. The lateral seams of the overalls contain fasteners 8, the return fasteners 9 are sewn to the surface of the cable 4. Safety belts 3 are equipped with an intelligent carbine 10, which Radio communication signals transmits data to a stationary control unit 11 in the workshop. The stationary control unit 11 in the workshop is equipped with a radio receiver 12, which receives information from the carabiner control unit and contains a storage device 13, a device for transmitting information to the central console 14 and a power source 15, as well as a processor 16 and a digital display panel 17. The intelligent carabiner 10 is equipped with a unit control 18, buzzer 19, LED indicators 20. The control unit 18 contains a power source 21, a display panel 22, a radio transmitter 23, an altimeter 24, a buzzer 19, a pulse transmitter 25 and a pulse receiver 26, and also a timer 27 for time tracking.

Overalls for work at height works as follows.

The overalls for work at heights have safety belts 3, smoothly turning into a reinforced cable 4, to evenly distribute the load on the body of the worker in case of a possible fall and to prevent injuries and injuries. The implementation of the cable from composite materials containing yarn of carbon fiber 5 and nylon 7, allows for its ease and high tensile strength. The use of optical fiber 6 provides, together with the elements of the control unit 18 in the carabiner 10, the pulse transmitter 25 and the pulse receiver 26, constant monitoring of the integrity and strain gauging (deformation) of the cable 4.

The lateral seams of the overalls contain Velcro fasteners 8, the reciprocal Velcro fasteners 9 are embedded in the elastic safety cable 4, thus, the cable 4 is securely fixed to the lateral seam of the overalls and does not interfere with the employee's movements at ground level.

The carbine 10 is equipped with a control unit 18 with an altimeter 24 and a buzzer 19, LED indicators 20, which are triggered if the worker is at a height at which there is a fixation to the fence, not fastened. The pulse transmitter 25 and the pulse receiver 26 in the control unit 18 of the carabiner 10 check the integrity of the cable 4 by interrogating with a set frequency. In case of breakage or significant deformation of the optical fiber 6, which is a weak link in the cable 4 in terms of its strength, the control unit 18 of the carabiner 10 transmits the corresponding data to the stationary control unit 11 via radio signals and turns on the light indication 20 and the buzzer 19 of the employee on the carabiner.

The altimeter 24, tuned to the appropriate height, also gives a signal of a possible violation, in fact, to the employee, reminding him, and to the central unit 11, which is located in the workshop and stores information about how long a particular employee was at a height not fastened ( or fastened) to protective guards, information is displayed on the digital display panel (LCD screen) 22.

Thus, this invention allows you to control the duration of workers at height while monitoring the status of the fixation of the cable with a carbine. In this case, safety violations can be avoided. In order to stimulate workers who regularly comply with safety regulations, incentive measures can be introduced for working hours at heights according to the flow chart, while eliminating possible violations for a significant time.
