Description
Technical Field
The invention relates to the field of adhesive tape transportation.
Background
The inclined shaft system of the Jianshan iron ore of Shanxi Tai Steel stainless Steel Limited company is responsible for rough breaking and transportation of raw ore, the elevation after the final descending section of No. 3 ore chute opening is 1218m, and the elevation after the final descending section of No. 4 ore chute opening is 1098 m; the No. 3 chamber and the No. 4 chamber in the lower part of the chute are at the elevation 1078 m. The main production flow is as follows: ore in the chute is conveyed to a jaw crusher by a heavy plate to be crushed, the granularity requirement of the ore is not more than 1000mm, the crushed granularity is not more than 350mm, and the crushed ore passes through a feeding small belt, an N04 belt conveyor and an N03 belt conveyor and then passes through a 3# driving station, an N02 belt conveyor and a cylindrical bin to a crushing system in the next process. The main equipment is as follows: heavy plate feeders a31, a41 of BWJ2400 × 12000 type, jaw crushers a32, a42 (2m × 1.5m, distributed in two crushing chambers), small feeding belts N33 (21m × 1.4m), N43(22m × 1.4m), main belts N04 (297 m × 1.2 m), N03 (2407 m × 1.2 m), N02 (1665 m × 1.2 m), which are centrally interlocked by an automation system.
N03 and N02 belong to the steel core sticky tape, and every 60 meters sticky tape inside is laid and is prevented tearing 8 word coils as the main protection device who detects the sticky tape, because the sticky tape is longer, prevents that the tearing device moves the back every time, and maintenance personal can't pinpoint the vulcanization and the fault is dealt with, not only leads to the sticky tape to idle for a long time, increases the power consumption, influences production organization and equipment maintenance efficiency moreover.
The original structure has the following defects: because the N02 adhesive tape and the N03 adhesive tape are both more than 1800 meters long, the positioning of the damaged part of the coil of the adhesive tape can only be confirmed by visual observation of a knife-engraved number, paint spraying is used for marking, 2-3 maintenance personnel need to stand in front of a vulcanization point for each maintenance, an accident switch is switched off to position and stop when the visual observation marking point is quickly operated to be close to the vulcanization point, but the operation speed of the adhesive tape is high (4.5 meters per second), the adhesive tape is difficult to accurately position and stop due to different reaction time of different personnel, and the adhesive tape needs to be stopped again to repeatedly position and stop after a proper vulcanization point is missed, so that the adhesive tape can be stopped to be at. And repeated parking can increase the idle time of the equipment and waste electric energy. According to statistics, at least 40 minutes are needed for each positioning parking, 3 motors are used for the N03 adhesive tapes, the installed power of each motor is 1450Kw, the power is required to be consumed by one hour of idling, and the electricity cost is reduced to 1700 kwh/h 0.5 yuan/kwh =850 yuan. Meanwhile, repeated parking wastes manpower, prolongs maintenance time, and frequent starting and stopping causes loss to a motor, a rubber belt disc brake, CST and the like, so that the service life of the equipment is shortened.

Detailed Description
The positioning and stopping device for installing the adhesive tape coil on the N03 vestibule adhesive tape machine of the tai-gang hill iron ore inclined shaft system is described as follows:
aiming at the problem that the coil and the fault part of the adhesive tape cannot be accurately positioned, the running edge of the adhesive tape is used as a detection point, when electrical tearing and fault parking occur each time, underground maintenance personnel confirm the number part of the adhesive tape, special reflective stickers (with the best effect of non-transparent objects of more than 1 mm) are adhered to the side faces of the adhesive tape to serve as receivers of photoelectric proximity switches, and reflective photoelectric proximity switch monitoring probe devices are arranged on two layers of belt racks of an east corridor outside a ground surface portal to serve as transmitters to dynamically monitor the edge of the adhesive tape machine. The light beam emitted from the emitter is reflected to the opposite reflecting mirror surface (receiver), when the light beam is interrupted, a switch signal is generated to change, the reflecting sticker is detected to send a parking instruction in time, the fault coil part can be accurately parked and fixed on the vulcanization point within 10 minutes at most, the coil is replaced, and the deviation between the fault coil part and the vulcanization platform parking position is realized+50 cm, and the position is accurate. Meanwhile, the reflective sticker can be recycled, and has the characteristics of low investment and high profit. The detailed steps are as follows
1. A reflective photoelectric proximity switch monitoring probe device (a photoelectric proximity switch transmitting device) is arranged on a belt frame on one side of two layers of a surface vulcanization point (a scheduled stop and overhaul point of the adhesive tape) to be used as a transmitter.
2. A reflecting sticker (with the best effect of a non-transparent object with the thickness of more than 1 mm) is adhered to a non-friction part on the side surface of the fault adhesive tape to serve as a receiver of the photoelectric proximity switch.
3. The normally closed contact fed back by the photoelectric proximity switch (emitter) is connected to an accident switch, and the emergency switch is in a standby state daily, such as the maintenance of a vulcanization coil device.
4. Dynamic supervision is carried out during maintenanceAnd (6) measuring. The process is as follows: under the running state of the adhesive tape, the light beam emitted from the emitter is reflected to the opposite reflecting mirror surface (receiver), when the light beam is interrupted, a switching signal is generated to change, a parking instruction is timely emitted within the rated time after the light-reflecting paster is detected, the fault coil part can be accurately parked and fixed in a vulcanization point (an adhesive tape scheduled parking maintenance point) within 10 minutes for coil replacement, and the coil is replaced with the vulcanization platform parking position and the deviation+50 centimetres, reflective paper can recycle once more simultaneously, and the position is accurate, reduces the sticky tape idle running and realizes the effect of stable, accurate detection.
