Abstract

The utility model discloses a safety belt alarm device for work high above ground, which comprises a box body, a power supply, a power supply switch, a metal slide block switch, a music storage trigger and a buzzer, wherein the power supply is connected in series with the power supply switch, the metal slide block switch and the music storage trigger, and the buzzer is connected with the music storage trigger. The metal slide block switch is composed of a hollow cavity, a spring piece and a metal slide block, the spring piece is arranged on one end of the hollow cavity, and the metal slide block is arranged in the hollow cavity. The alarm device is attached below a self-lock hook of a safety rope for the existing safety belt, and the power supply switch of the alarm device is opened before the work high above the ground starts. When the safety belt is not hung and fastened, the alarm device can send out alarm and reminds operating personnel to fasten the safety belt, so the safety of the personnel who work high above the ground is enhanced. The alarm device has the advantages of simple structure and convenient installation and operation.

Description

Work high above the ground safety belt warn device

(1), technical field:

The utility model relates to a kind of safeguard protection articles for use of work high above the ground, relates to a kind of work high above the ground safety belt warn device particularly.

(2), background technology:

According to the provisions of the relevant regulations issued by the State, in the work high above the ground that height of fall datum level (contains 2 meters) more than 2 meters, require the operating personnel to fasten seat belts, and safety belt must be to hang on the firm member of top, construction operation place, should high hang (being) low usefulness, must not adopt what be lower than the waist level is hanging method.Yet in work high above the ground, the operating personnel often forgets to be hanging safety belt, is easy to cause security incident.

(3), summary of the invention:

Technical problem to be solved in the utility model provides a kind ofly can remind that the work high above the ground personnel are the work high above the ground safety belt warn device of hanging safety belt.

In order to solve the problems of the technologies described above, technical solution of the present utility model is such, this work high above the ground safety belt warn device comprises that box body, power supply, power switch, metal slider switch, music store trigger, buzzer, wherein, power supply and power switch, metal slider switch, music store trigger and are in series, and buzzer stores trigger with music and is connected; Described metal slider switch is made of cavity, spring leaf, metal slide block, and spring leaf is located on the end of cavity, and the metal slide block is located in the cavity.

Owing to be provided with metal slider switch, music storage trigger etc. in the warn device of the present utility model, with the below of this warn device attached to the safety rope latch nook of existing safety belt, before the beginning work high above the ground, the power switch of warn device is opened, if safety belt does not have high the extension to fasten, warn device will send and warn, and reminds the operating personnel to fasten seat belts, and has improved the work high above the ground safety of persons.Shutting power switch when safety belt is obsolete gets final product.This work high above the ground safety belt warn device is simple in structure, installs, operation is very easy, is work high above the ground personnel necessary security protection articles for use.

Fig. 1 is the utility model work high above the ground safety belt warn device internal structure schematic diagram;

Fig. 2 is the cutaway view of warn device A-A shown in Figure 1;

Fig. 3 is the circuit theory diagrams of the utility model warn device;

Fig. 4 is the user mode figure of the utility model warn device.

(5), the specific embodiment:

By Fig. 1, Fig. 2, Fig. 3 as seen, the utility model work high above the ground safety belt warn device comprises that box body 1, power supply 2, power switch 3, metal slider switch 4, music store trigger 5.Power switch 3 is located at the upside of box body 1; Power supply 2 can adopt electronic cell or other battery pack, is positioned on the circuit board 10, stores trigger 5 and contacts mutually with power switch 3, metal slider switch 4, music; Buzzer 6 stores trigger 5 by lead and music and is connected.Described metal slider switch 4 is made of cavity 7, spring leaf 8, metal slide block 9, spring leaf 8 is located on the end of cavity 7, be provided with chute on the two side of cavity 7, metal slide block 9 slides up and down in cavity 7 along chute, also is provided with lead on the metal slide block 9 and is connected with circuit board 10.Drive lead when preventing that metal slide block 9 from sliding up and down in cavity 7 and pull up and down and open circuit easily, can establish a spring leaf again at an end of cavity 7 and replace lead.Music stores trigger 5 and also is positioned on the circuit board 10, can adopt the integrated package of integrated circuit F-6A or other suitable types.The effect that this music stores trigger 5 is store voice information and sends the voice suggestion signal, sends voice suggestion by buzzer 6 after circuit enlarges, and as " Buckle Up " etc., also can be music and warns.

Operation principle of the present utility model is as follows: as shown in Figure 4, with the below of this warn device attached to safety rope 12 latch nooks 11 of existing safety belt, an end of band spring leaf 8 is up near latch nook 11.Before the beginning work high above the ground, the power switch 3 of warn device is opened, make warn device be in normal operating conditions, if safety belt does not have high the extension to fasten, because the gravity effect of safety belt latch nook 11, safety belt latch nook 11 meeting natures are sagging, metal slide block 9 in the warn device slides to the spring leaf 8 of cavity 7 one ends and contact with it, power switch 3 in the circuit, metal slider switch 4, music stores trigger 5, buzzer 6 forms closed circuit, this warn device circuit on-state just shown in Figure 1, at this moment buzzer 6 sends and warns, and reminds correct the fastening seat belts of operating personnel.Correct is to hang up properly safety belt, and latch nook 11 hangs on the fixture of operation place top, and metal slide block 9 slides to the other end of cavity 7, and then the circuit of warn device disconnects, and buzzer 6 is warned and stopped, but just operate as normal of operating personnel.Shutting power switch when safety belt is obsolete gets final product.
