Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present invention will now be described in detail with reference to the accompanying drawings.

The utility model provides a mining support displacement monitor, includes support 1 of fixed stock anchor rope, 1 below fixed mounting of support has monitoring frame 2, monitoring frame 2 inside both sides are installed respectively and are monitored first sensing device 3 of 1 displacement of tunnel both sides support to carry out the early warning of feeding back through first warning light 11, monitoring frame 2 is interior upper end is installed and is monitored second sensing device 4 of 1 displacement of tunnel top support, feeds back the early warning through second warning light 14.

As shown in fig. 1-2, when monitoring, the first sensing device 3 of the inside upper end both sides of monitoring frame 2 monitors the support 1 of tunnel both sides, if the condition of the too big support body skew of pressure appears in support 1 of both sides, then first warning light 11 then sends early warning signal, the staff also can judge which side's support 1 displacement is too big through the signal, and the monitoring at tunnel top monitors through second sensing device 4, if the displacement appears too big, then second warning light 14 sends early warning signal.

According to one embodiment of the utility model, the first sensing device 3 comprises a transmission rod 6 hinged on a hinge seat 5, the hinge seat 5 is connected to one side of the support 1 in a sliding manner, the transmission rod 6 and a first bevel gear 7 fixedly connected to the other end of the transmission rod are rotatably connected in the monitoring frame 2, the first bevel gear 7 is meshed with a second bevel gear 9 connected to one end of a threaded rod 8, a sliding block 10 is connected to the threaded rod 8 in a threaded manner, and a switch of a first warning lamp 11 is installed in the sliding direction of the sliding block 10.

The drift appears in the tunnel of both sides, can extrude 1 both sides of support and appear the displacement deformation, thereby can make articulated seat 5 slide during the deformation and drive transfer line 6 and first bevel gear 7 and take place to rotate, rotate with it engaged second bevel gear 9 and threaded rod 8 together for slider 10 takes place the displacement, touches the switch of its ascending first warning light 11 of slip direction behind the displacement certain distance, sends early warning signal.
