Description

The dropproof safety alarm device in hole

Technical field

The utility model belongs to the technical field of construction safety protection, more particularly to a kind of dropproof security warning dress in hole Put and combine.

Background technology

When building interior is constructed, the floor or platform of eminence often have some holes, these holes often not by Note, in outside, construction would generally hang up the safety rope of Anti-fall to construction worker on safety belt, but when internally constructing, defence Psychology can weaken, and the length of safety rope is inadequate, when running into hole, when particularly retreating, is very easy to drop；It is existing super Sound ranging alarm can measure the risk distance of setting and be alarmed, and such as reversing is reminded；Existing ultrasonic ranging Device being capable of Accurate Determining distance；But it is a lack of a kind of suitable combination ultrasonic ranging alarm is connected into operation applying On the safety belt of workman person.

Utility model content

In order to solve the above-mentioned technical problem, the utility model provides a kind of dropproof safety alarm device in hole.

The technical solution of the utility model is：A kind of dropproof safety alarm device in hole, including safety belt, its feature exist In, in addition to ranging alarm, the safety belt includes safety belt main body and at least one contiguous block, before the contiguous block includes The T-shaped neck in face and the threading at back mouthful, the bottom center of the T-shaped neck are provided with hemispheric detent, the ranging The back side of alarm is provided with to be coordinated and T-shaped clamp with bonnet with T-shaped neck, the center of the T-shaped clamp provided with sinking and It is placed with compression spring and is the spring groove of cylinder, is additionally provided with the locating rod stretched into compression spring in the spring groove, it is described The left end of locating rod is hemispherical and the projection coordinated with detent, and the locating rod is additionally provided with the right side of projection and is ring The clamp of shape, the right flank of the clamp is fitted with the left end of compression spring, and the bonnet of the T-shaped clamp is provided with for projection protrusion Circular hole, the diameter of the circular hole is less than the diameter of section of spring groove.

It is preferred that, the probe of cylinder, the probe are tilted down provided with front end and are before the ranging alarm Ultrasonic transmitter-receiver is inside installed, the upper end of the ranging alarm is provided with buzzer, and the inside of the ranging alarm is set There are the AT89C51 single-chip microcomputers being connected with ultrasonic transmitter-receiver, buzzer.

It is preferred that, the angle that the front end of the probe is tilted down is 30 ° -60 °.

The beneficial effects of the utility model are：

The dropproof safety alarm device in hole of the present utility model, can detect the hole of building interior, prevent workman from falling Fall；The ranging alarm being arranged on safety belt is set, the inside of T-shaped neck is arranged on using T-shaped clamp, facilitates ranging to alarm The installation of device and retract；Locating rod and detent are set, can make ranging alarm is stable to be arranged on safety belt, and Set and compression spring and ring baffle are set in locating rod, tension force is provided for locating rod, increase the stability of ranging alarm.
