Embodiment 1

[0039]A new type of alarm device for a steel cable lifeline system, comprising an alarm mechanism 1, a linkage mechanism 2 and a drive module 3, the alarm mechanism 1 including a pull rod 11, a reinforcement buckle 12, an electric wire 13, a tension spring 14, an electromagnetic The sensor 15 and the connecting rod 16, the side end of the pull rod 11 is connected with the reinforcement buckle 12, the other end of the pull rod 11 is connected in series with the electric wire 13, the two ends of the reinforcement buckle 12 run through a tension spring 14, and the electric wire 13 Through the inner cavity of the electromagnetic sensor 15, the other end of the tension spring 14 is engaged with the connecting rod 16. The pull rod 11 includes a pulling base frame 111, an embedded block 112, a series rod 113 and a mounting screw 114. The pulling base frame 111 The inner cavity is interspersed with an embedded block 112, one end of the embedded block 112 is installed with a series rod ...

Embodiment 2

[0041] The linkage mechanism 2 includes an alarm box 21, an inner connecting piece 22, a check switch 23, a battery 24, a penetrating screw 25 and an audible and visual alarm 26. The four corners of the alarm box 21 are flexibly connected by the inner connecting piece 22, and the alarm box A check switch 23 is provided on the side end surface of 21, and one side of the check switch 23 is electrically connected to the storage battery 24. The alarm box 21 and the inner connecting piece 22 are connected in series through a penetrating screw 25. The alarm box 21 The bottom end face is provided with a sound and light alarm 26, and the alarm box 21 includes a fixed side plate 211 and a connecting plate 212, and the connecting plate 212 is installed between the fixed side plates 211, and the driving module 3 is composed of a switch 31, an indicator switch 32 and an indicator light 33. The switch 31, the indicator switch 32 are electrically connected with the indicator light 33, the sw...

Embodiment 3

[0043] In addition, when the top end of the pull rod 11 of the overall device is connected to the external lifting mechanism, the overall device is placed vertically with the connecting rod 16 as the vertical foot. When the gravity bearing weight under the connecting rod 16 exceeds the preset threshold, the The pull rod 11 remains still but the connecting rod 16 stretches the tension spring 14 downward due to gravity. At this time, the distance between the mounting screw 114 and the electromagnetic sensor 15 becomes larger, thereby starting the current and transmitting the signal to the sound and light alarm 26. The overall The device is equipped with an inspection switch 23 to check whether the current of the circuit is always in the energized state and connected to the battery 24. Personnel can check and replace the battery in time through this setting to ensure that the system is always in a charged and normal working state. When the weight exceeds the preset threshold, the ...

Abstract

The invention discloses a novel alarm device for a steel cable type lifeline system and belongs to the technical field of operation safety equipment. The novel alarm device for a steel cable type lifeline system comprises an alarm mechanism, a linkage mechanism and a driving module, when a top end of a pull rod of the whole device is connected with an external lifting mechanism, the whole device is vertically placed with a connecting rod as a vertical foot, and when the lower gravity bearing weight of the connecting rod exceeds a preset threshold value, at the moment, the pull rod is kept still, but the connecting rod downwards stretches the tension spring due to gravity, and a distance between a mounting screw and an electromagnetic sensor is increased, so the current is started, and a signal is transmitted to an audible and visual alarm, and the whole device is provided with a checking switch for checking whether the current of the circuit is always kept in a power-on state and is kept connected with the storage battery; personnel can check and timely replace the battery through the setting so as to ensure that the system is always in an electrified normal working state.

Description

technical field [0001] The invention relates to the technical field of operation safety equipment, and more specifically relates to a novel alarm device for a steel cable lifeline system. Background technique [0002] As the safety of working at heights has been paid more and more attention, the horizontal lifeline fall arrest system has been more and more used in high-altitude marginal positions such as industrial plants, high-rise buildings, and petrochemical industries. As a horizontal lifeline to protect the safety of workers at heights, in addition to the obvious safety requirements such as the physical strength of the equipment, system users have put forward higher requirements for the hidden safety of ensuring the timeliness of rescue after an accident. When the staff wear After a fall accident, the safety belt will hang on the lifeline under the action of the horizontal lifeline. After a worker wearing a seat belt hangs in mid-air for a certain period of time, he wi...
