Detailed Description

As shown in fig. 1-3, an explosion-proof safety isolating device comprises a pneumatic isolating barrier 15, a first position sensor 1, a second position sensor 2 and a controller 3; a pneumatic isolation barrier 15 is arranged between the dangerous area and the safety area; a first position sensor 1 and a second position sensor 2 are sequentially arranged on a travelling track 16 of the dangerous area along the travelling direction; the first position sensor 1 and the second position sensor 2 are respectively positioned at two ends of the pneumatic isolation gate 15; an infrared sensor 4 is arranged on one side of the safety area close to the pneumatic isolation barrier 15, and an audible and visual alarm 5 is arranged at one end of the pneumatic isolation barrier 15.

The pneumatic isolation fence 15 comprises a support frame 8, a cylinder 6, a disc 9, a bearing seat 10, a rotating rod 11 and an isolation rod 14; rotate on support frame 8 and install cylinder 6, disc 9 is articulated with the flexible end of cylinder 6, and the one end of dwang 11 runs through the centre bore of disc 9 and fixes on support frame 8 through the rotation of bearing frame 10, disc 9 and dwang 11 fixed connection, the other end of dwang 11 and the one end lateral wall fixed connection of isolating rod 14.

A protective box 7 is covered on the outer sides of the air cylinder 6, the disc 9, the bearing seat 10 and the support frame 8, and a rotating rod 11 movably penetrates through the protective box 7; the audible and visual alarm 5 is arranged at the top of the protective box 7; the infrared sensor 4 is installed at a position 2m in the horizontal and vertical direction from the spacer bar 14. The device also comprises an inserted bar 13 and a concave fixing frame 12, wherein external threads are arranged at two ends of the inserted bar 13, and a plurality of through holes are formed in the disc 9; the inserted bar 13 runs through the through hole, two ends of the inserted bar 13 pass through the fixed frame 12 and are fixed through nuts, and the bottom of the fixed frame 12 is fixedly connected with the top of the telescopic end of the cylinder 6.

As shown in fig. 4, the signal output ends of the first position sensor 1 and the second position sensor 2 are connected with the signal input end of the controller 3 through signals; the signal output end of the controller 3 is connected with the signal input end of the air cylinder 6 of the pneumatic isolation barrier 15 through a signal. The signal output end of the infrared sensor 4 is in signal connection with the signal input end of the controller 3; the signal output end of the controller 3 is connected with the signal input end of the audible and visual alarm 5 through signals.

The working principle is as follows:

when the trolley 17 runs to the first position sensor 1 along the running track 16, the first position sensor 1 detects the trolley 17 and transmits a signal to the controller 3, the controller 3 controls the cylinder 6 to operate, the telescopic end of the cylinder 6 is shortened, and the disc 9 is driven to rotate, so that the isolating rod 14 falls down, and the effect of isolating the safe area from the dangerous area is realized. When the trolley 17 runs to the second position sensor 2, the second position sensor 2 detects the trolley 17 and transmits a signal to the controller 3, the controller 3 controls the cylinder 6 to operate, the telescopic end of the cylinder 6 extends to drive the disc 9 to rotate, so that the isolating rod 14 is lifted, and the effect that an operator can safely pass through is achieved.

When the isolating rod 14 is located at the falling position, if a person tries to pass through the isolating rod 14 to enter a dangerous area, the infrared sensor 4 located 2m in front of the isolating rod 14 detects that the person approaches, a signal is transmitted to the controller 3, and the controller 3 controls the audible and visual alarm 5 to operate, so that the warning effect is achieved. After the trolley 17 safely passes through the second sensor, the controller 3 receives signals transmitted by the second sensor, controls the cylinder 6 to operate, lifts the isolating rod 14, and meanwhile, the audible and visual alarm 5 releases the alarm, so that the operators can pass through the isolating rod smoothly. And when the isolating rod 14 is in the lifted state, the infrared sensor 4 is not activated.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
