Description
Technical field
The utility model relates to accident warning devices, more particularly, to pin shaft accident warning device.
Background technique
In existing underground coal mine production technique, face pressure is acted directly on hydraulic support, and hydraulic support is work
Make the mostly important support apparatus in face.The main components of hydraulic support are all to be connected by pin shaft, therefore pin shaft is hydraulic branch
Main power transmission point between frame structural member.Pin shaft by that can deform often compared with big load at work because being even broken, such as
Fruit pin shaft generates moderate finite deformation, will affect the relative motion between structure, once pin shaft is broken, will jeopardize coal-getter
Make the personal safety of operator near hydraulic support in face.At present to pin shaft failure check mainly by manual type into
Row is inspected periodically, but due to the limitation of subsurface environment, artificial investigation is difficult to real-time complete detection and is easy to produce careless omission in turn
Leave security risk.Thus, pin shaft failure deformation or breaking state are detected and alarmed in real time is raw for safety of coal mines
Production is of great significance, while being also a problem to be solved.
Summary of the invention
The utility model aim is to provide a kind of pin shaft accident warning device.
To achieve the above object, the utility model takes following technical proposals:
Pin shaft accident warning device described in the utility model, including be installed in pin shaft centre bore and be made of translucent material
Closed cylindricality detection pipe, the optical detecting unit of cylindricality detection pipe one end is set；It is provided in the cylindricality detection pipe
For filling the first bearing cavity and the second bearing cavity of chemical combination substance；The optical detecting unit is the encapsulation for offering installation room
Body, the installation interior are provided with photosensitive detection device, the signal output end of the photosensitive detection device and combined aural and visual alarm
Control signal input connection, it is indoor that cylindricality detection pipe one end extends to installation.
First bearing cavity is located in the second bearing cavity.
The utility model advantage is compact-sized, versatile, cheap.Cylindricality detection pipe is closed tubulose knot
Structure has the characteristics that waterproof and dustproof, is very suitable to underground use.Meanwhile photosensitive detection device is automatically controlled as combined aural and visual alarm
Element has the characteristics that low-power consumption, essential safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the portion the I enlarged structure schematic diagram of Fig. 1.
Specific embodiment
It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, 2, pin shaft accident warning device described in the utility model, including be installed in 1 centre bore of pin shaft
The closed cylindricality detection pipe 2 made of glass, is arranged in the optical detecting unit of 2 one end of cylindricality detection pipe；It is set in cylindricality detection pipe 2
It is equipped with the first bearing cavity 3 and the second bearing cavity 4 for filling chemical combination substance；Optical detecting unit is the envelope for offering installation room 5
Body 6 is filled, installs and is provided with photosensitive detection device 7 in room 5, the signal output end of photosensitive detection device 7 passes through signal cable 8 and sound
The control signal input of light crossing-signal 9 connects, and one end of cylindricality detection pipe 2 extends in installation room 5.
When the utility model is used, different chemical combination substances is filled respectively in the first bearing cavity 3 and the second bearing cavity 4, when
When pin shaft 1 occurs to cause when large deformation the first bearing cavity 3 in cylindricality detection pipe 2 to rupture, the first bearing cavity 3 and the second bearing cavity
Two kinds of chemical combination material mixings in 4 occur combination reaction and shine, and the light of sending triggers photosensitive detection device 7, photosensitive detection member
Detection signal is exported after part 7 gives combined aural and visual alarm 9 control terminal, and combined aural and visual alarm 9 issues alert notice related personnel progress at once
Maintenance.
