Abstract
The invention provides an automatic alarm for the imbalance of a plane of a work room of a tower crane. According to the principle that mercury conducting liquid is combined with the structure of a spirit level, a triangular sitting disc of the spirit level is arranged on a desktop of the work room of the tower crane, three screw studs are fixed on the desktop of the work room of the tower crane, six screw caps adjust the triangular sitting disc for horizontal positioning, the work room of the tower crane rotate for a circle, the position of the center of a mercury bubble in the spirit level is not changed. The mercury conducting liquid in the spirit level is provided with a metal lead at the bottom in the spirit level, another metal lead is arranged at the center point of the spirit level; once a rocker arm of the tower crane stretches and concrete, reinforcing steel bars and other articles are overloaded, the plane of the work room inclines, the mercury bubble in the spirit level moves up, the two metal leads in the spirit level are in contact by virtue of the mercury conducting liquid, 3V-100-milliampere microcurrent generates an electromagnetic force through a relay J1 so as to attract an armature, so that a circuit 1 and a circuit 2 are closed; a relay J2 with 220v-15w power supply generates electromagnetic force alternating-current current to vibrate an armature hammer to beat a bell so as to send out bell sound, so that the automatic alarm is necessarily equipped for the safety of high-rise building construction.
Description
The present invention belongs to Architectural Equipment, relates to crane machine, surveys Static pressure pile driver horizontal device, the particularly flat autoalarm of a kind of crane machine operating room plane dehydration.
Present known Architectural Equipment crane machine operating room planar horizontal is to adopt " bubble level " naked-eye observation of concentrating one's energy, and this quadrat method is very backward.Purpose of the present invention is for the flexible overload of existing crane machine rotation arm article, the plain row automatic alarm of plane, operating room dehydration.
Technical solution of the present invention, the mercury conducting liquid is in conjunction with the reason of " bubble level " structure, at first " bubble level " triangle is taken position and be arranged on the crane machine operating room desktop, three screw columns fixedly on the tower crane operating room desktop, six nuts adjust the triangles horizontal location of taking position, crane machine operating room circumference " bubble level " mercury bubble maintenance center invariant position that turns around.Mercury conducting liquid end in " bubble level ", arrange a plain conductor in described " bubble level ", another root plain conductor arranges on " bubble level " center-point, in case the article such as the flexible overload of crane machine rotation arm cement concrete, reinforcing bar, mercury bubble upward displacement in plane, the operating room inclination " bubble level ", two plain conductors are touched by the mercury conducting liquid and close in " bubble level ", and the little electric current of 3V-100 milliampere passes through J
1Relay produces electromagnetic force and holds armature, makes circuit 1 and circuit 2 closed 220V～15W power supply J
2Relay generation electromagnetic force alternating current vibration armature hammer beats clock and sends electric bell sound, points out the flexible overload of this crane machine rotation arm article.
The flat autoalarm of crane machine dehydration provided by the invention is characterized in that reminding technical personnel in the crane machine operating room, and the immediately shut-down operation of crane machine rotation arm flexible overload article avoids construction to have an accident.
Make below in conjunction with Figure of description and to explain.
In the accompanying drawing: 1, bubble level 2, three screw columns are fixed 3, six nuts 4, triangles take position 5, plain conductors 6, another root plain conductor 7, mercury bubble 8, armature 9, electromagnetic vibratory moving armature hammer 10, electric bell sound
Shown in Figure of description: the mercury conducting liquid is in conjunction with the reason of " bubble level " structure, at first " bubble level " (1) triangle is taken position and be arranged on the crane machine operating room desktop, three screw columns are fixed on (2) tower crane operating room desktop, six nuts (3) are adjusted triangle (4) horizontal location of taking position, crane machine operating room circumference turns around, and mercury conducting liquid end " bubble level " in, arrange on another root plain conductor (6) setting " bubble level " center-point of a plain conductor (5) in " bubble level " mercury bubble maintenance center invariant position " bubble level ", in case the flexible overload of crane machine rotation arm article, mercury bubble (7) upward displacement in plane, the operating room inclination " bubble level ", two plain conductors are touched by the mercury conducting liquid and close in " bubble level ", and the little electric current of 3V-100 milliampere passes through J
1Relay generation electromagnetic force holds armature (8) makes circuit 1 and circuit 2 closed 220V～15W power supply J
2Relay generation electromagnetic force alternating current vibration armature hammer (9) beats clock and sends electric bell sound (10)
