Description
Technical Field
The utility model relates to a safety inspection technical field, more specifically the safety belt that automatic detection hangs height usefulness that says so relates to one kind.
Background
At present, the safety belt is the necessary protective equipment for high-altitude operation. It is known that in the industrial production process, the casualty accident rate caused by falling due to the insufficient safety factor of the safety belt and the irregular operation of workers is quite high. The human body falling accidents account for about 15 percent of the industrial accidents. High fall casualty is associated with many factors, such as human factors, physical factors, environmental factors, regulatory factors, work level, etc., and among them is primarily associated with work level. According to the statistical analysis of high-altitude falling accidents, the falling accidents of the high-altitude operation with the height of more than 5m account for about 20 percent, the falling accidents of the high-altitude operation with the height of less than 5m account for about 80 percent, and most of the falling accidents are fatal accidents. It follows that it is necessary to prevent falls from heights and to take personal protection measures. It has been found that most of the falling persons fall on the ground in the supine or prone position when they fall carelessly, and at the same time, the maximum impact force that the abdomen (waist) of a person can endure is relatively large for the whole body. This becomes an important basis for the use of the seat belt. Since the degree of injury from falling is related to the height of the fall, it is common that operations on a base level of 2m (including 2m) or more are defined as operations at height, and it is regulated that personal protection measures are required for operations at height. The function of the safety belt is very obvious: the safety device can ensure that an operator can safely work at a high place, and can effectively avoid huge damage to a human body caused by falling from the high place in case of an accident.
However, when the safety belt is used by the personnel working aloft, the personnel is easy to hang at a low position, namely the hook of the safety belt is hung at a low position, and the gravity center of the personnel is higher than the position of a hanging point; under the condition, when falling, the falling distance of the human body is increased, the human body and the safety belt are subjected to larger impact load, and the probability of human body injury is increased. It is not permissible for the height of the harness suspension point to be below the person's center of gravity. In addition, the prior art is complex, the implementation cost is high, the wireless communication function is not provided, only field prompt can be carried out when violation is found, safety personnel cannot be informed to carry out recording and checking in time, and management loopholes exist. Moreover, the application range is small, the detection gravity center cannot be adjusted, and the detection sensitivity is low.
Therefore, how to realize adjustable detection center of gravity, and have wireless communication function, but remote monitoring, high detection sensitivity is a problem that needs to be solved urgently by those skilled in the art.

When the contact sensor at the hook does not sense that an object is in contact, namely the hook is not hung on the object, the signal of the liquid pressure sensor is suppressed, the circuit can not be started, or the MCU judges that the safety belt is not used at the moment, and simultaneously transmits the information to the information receiving device through the wireless device, wherein the information receiving device can be an internet of things platform, a rear-end server, an intelligent terminal of a guardian, or a combination of the above devices.
The use method of the liquid pressure sensor comprises the following steps: the liquid conduit of junction connects the three-way valve, and one end is connected the liquid conduit, and liquid pressure sensor is connected to one end, and atmosphere is connected to one end, connects the atmosphere and goes out to separate through the diaphragm, and this diaphragm has the effect of hindering liquid to ventilate. When the end A is lower than the end B, the hose is filled with liquid, and the liquid level of the end A is lower than the liquid level of the end B, so that liquid pressure exists at the end A, the pressure sensed by the liquid pressure sensor is higher than atmospheric pressure, the state of the liquid pressure sensor is an a state, and the safety belt is used for hanging up. When the end A is higher than the end B, air exists at the end A, the pressure sensed by the liquid pressure sensor at the end A is equal to atmospheric pressure, the liquid pressure sensor is in a state B, and the safety belt is used in a high-hanging mode and a low-hanging mode and is normally used.
The principle of the double-hook safety belt is the same as that of the double-hook safety belt, and the double-hook safety belt is different in that the double-hook safety belt is provided with two connecting belts and hooks, and a hose, a liquid pressure sensor and a contact sensor are matched with the two connecting belts and the hooks.
