The bottom of universal joint is fixedly connected, and the top of the high-precision universal ball joint is fixedly connected with adjusting the bottom of screw mandrel, the tune
Whole screw mandrel top is spirally connected with the top cover at the top of the mounting cylinder, and the output end of the sophisticated sensor passes through signal wire and the biography
Sensor instrument is connected, and the alarm lamp is also connected with the sensor apparatus by signal wire.
Preferably, guide pad is installed with the mounting cylinder inwall, the guide pad center offers pilot hole, institute
State detection bar the other end pass through the pilot hole after with it is described detection ball lower rotation be connected.
Preferably, a diameter of 50-60mm of the mounting cylinder.
A kind of deformation of deep excavation tilts monitoring alarm in the embodiment of the present invention, including be sequentially connected mounting cylinder, pass
Sensor instrument and alarm lamp, sophisticated sensor, the detection bar top of sophisticated sensor is fixedly mounted in mounting cylinder inner bottom surface
End is stretched out and is connected with detection ball rotation connection, detection top dome portion by high-precision universal ball joint with adjusting bolt, adjusting bolt
It is screwed onto on the top cover of mounting cylinder, sensor apparatus is connected with sophisticated sensor.Device is arranged in foundation ditch, once run-off the straight
Ball is detected afterwards keeps vertical state, and detection bar run-off the straight inside sophisticated sensor, sensor apparatus display precision sense
The displacement of device, alarm lamp is controlled to light when gradient exceedes preset value.Simple in construction, easy to use, entirety is not only
It may be mounted at foundation ditch periphery and detect the inclination and offset situation of sensing deep basal pit in real time, while can also be placed in drilling in real time
The situation of change of detection drilling introversion rake angle, and the present apparatus can effectively sense 360 degree of any directions in specific implementation
Tilt variation no more than 30 degree, its overall sensitivity is greatly improved, be easy in early stage with regard to the water of foundation ditch can be detected
The situation of change of gentle high inclination, overall security is greatly improved, reduce its entirety to artificial accordance with tolerance.
Brief description of the drawings

There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation that a kind of deformation of deep excavation provided in an embodiment of the present invention tilts monitoring alarm；
Fig. 2 is mounting cylinder heeling condition schematic diagram in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Reference picture 1, a kind of deformation of deep excavation provided in the embodiment of the present invention tilt monitoring alarm, and the device includes
Mounting cylinder 1, sensor apparatus 10 and alarm lamp 11.
The mounting cylinder 1 is cylindric hollow cylinder, and its is closed at both ends, and the bottom of mounting cylinder 1 is sensor installation seat 2,
There is mounting groove on the top surface of the sensor installation seat 2, sophisticated sensor 3, the essence are installed with the mounting groove
One end of detection bar 4 of close sensor 3 is movably arranged on inside the sophisticated sensor 3, and the other end pushes up from the sophisticated sensor 3
Portion is stretched out.The other end of the detection bar 4 passes through the bottom being fixed on after the guide pad 5 on the inwall of mounting cylinder 1 with detection ball 6
Portion is rotatablely connected.The center of guide pad 5 offers pilot hole, the detection bar 4 be located in the pilot hole can ensure it is described
The degree of accuracy of detection bar 4.The top of the detection ball 6 is fixedly connected with the bottom of high-precision universal ball joint 7, described high-precision spherical
The top of universal joint 7 is fixedly connected with adjusting the bottom of screw mandrel 8, the top on the adjustment top of screw mandrel 8 and the top of mounting cylinder 1
Lid 9 is spirally connected.
The output end of the sophisticated sensor 3 is connected by signal wire with the sensor apparatus 10, the police instruction
Lamp 11 is also connected with the sensor apparatus 10 by signal wire.
In the present embodiment, a diameter of 50-60mm of the mounting cylinder 1, can be free to enter in foundation ditch.
As shown in Fig. 2 described device is when in use, the inclination of foundation ditch can cause the device to tilt, and the device is examined after tilting
Ball 6 is surveyed because deadweight can rotate around high-precision universal ball joint 7, to remain vertical state, and now after the device tilts,
