A dual-control safety belt with an alarm device

Abstract

The invention discloses a double-control safety belt with an alarm device. The double-control safety belt comprises a safety belt back plate, an alarm box is arranged on the safety back plate, an auxiliary fixing buckle is hinged to the alarm box, the alarm box comprises a box body and a box bottom plate, a power supply is arranged in the box body, and a buzzer is arranged at the upper end of the box body. According to the double-control safety belt, when a safety buckle is not buckled on the auxiliary fixing buckle, a triangular jacking block is extruded by the back of a worker in the operation process so as to move towards the inside of the box body, a first electrode plate and a second electrode plate are driven to make contact through the extrusion effect on the triangular jacking block by the back of the worker, and therefore a working circuit of the buzzer is connected, and the buzzer works to remind the worker to connect the safety belt; and the safety buckle is buckled on the outer side of a sliding rod and drives a pull rod to move outwards under the gravity action of the safety buckle, and therefore a contact plate is pulled to enable the two electrode plates to keep a larger distance, and the worker does not trigger the alarm device during work.

Description

technical field [0001] The invention relates to the field of safety belts, in particular to a dual-control safety belt with an alarm device. Background technique [0002] At present, according to the requirements of safe work regulations, staff working on scaffolds without scaffolds or railings above 1.5M from the ground should use double-control safety belts, and the safety ropes should be hung on strong and firm components during work. Hang high and use low. However, according to the relevant accident notification cases, we found that some workers still took time to save trouble during the actual high-altitude operations and did not use safety ropes, resulting in fatal accidents of personnel falling from high altitudes. In order to prevent the staff from incorrectly using the dual-control seat belt when working at heights, thereby avoiding the occurrence of high-altitude fall accidents, we propose a dual-control seat belt with an alarm device to solve the above problems. ...
