Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1, an anchor cable withdrawal alarm device comprises two adjustable screws 1, two trays 2, two brackets 3, two pressing plates 4, an anchor cable 5, two expansion springs 6, a pressure sensor 7, magnetic steel 8 and an audible and visual alarm module; tray 2 is through setting up respectively in the 1 roof pressure of adjustable screw at two supports 3 both ends on the roof absciss layer, and two supports 3 other ends are dragged through the top board, are equipped with two expanding spring 6 between top board and the holding down plate to connect 5 through the anchor rope that sets up in the middle of the top board and the holding down plate, the lower surface of holding down plate and the 5 junctions of anchor rope is equipped with audible-visual annunciator module, and holding down plate one side is equipped with pressure sensor 7 and is used for measuring the gravity that the holding down plate receives, and with signal transmission to audible-visual annunciator module.
As shown in fig. 2, the audible and visual alarm module includes 3 groups of alarm lamps and a dc power supply module for supplying power to the alarm lamps, each group of alarm lamps is further provided with an alarm indicator lamp correspondingly, and the dc power supply module is further provided with a power supply indicator lamp for displaying the power supply state; each group of alarm lamps is controlled to be switched on and switched off through a relay, and signals of the pressure sensors received by the relays are sucked after exceeding a preset threshold value, so that the whole audible and visual alarm circuit forms a passage.
The underground power supply voltage is 660V, and the voltage levels of a relay, an indicator light and the like in the explosion-proof switch are 127V; the scheme adopts the transformer to reduce the voltage to 127V for the audible and visual alarm module to use.
In this embodiment, the anchor rope that provides moves back anchor alarm instrument before the roof takes place to fall, utilizes the roof phenomenon such as abscission layer, crack to appear, in time sends the warning, reminds operation personnel this section roof to have the danger that takes place to fall, can in time effectual tissue personnel withdraw this section after the personnel confirm, prevents that the accident from further expanding, has ensured the life safety of staff in the pit.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
