The belt conveyor has irreplaceable effects in coal mine production due to the advantages of large conveying capacity, simple structure, low cost, strong universality and the like, and is main equipment for realizing the transportation of coal from an underground coal face to the ground. The adhesive tape with the steel wire rope core is used as a carrier for bearing and transporting coal, and in the long-time use process, the friction between the tape surface and materials and the friction between the adhesive tape and a roller can cause the tape surface of the adhesive tape to be scratched, even accidents such as tape breakage, tape sliding and the like occur, so that the adhesive tape is required to be replaced regularly in order to ensure the safe and stable operation of the adhesive tape. However, as coal mining gradually develops toward deep portions, deep mining causes the gradual popularization of ultra-long-distance belt conveyors with conveying distances of over kilometers, the ultra-long-distance belt conveyors are usually large in power and large in transportation capacity, and the rubber belts of the ultra-long-distance belt conveyors are usually of a structure that a plurality of rubber belt sections are connected into a whole through rubber belt joints, so that the ultra-long-distance belt conveyors are large in size and weight, complex in underground working condition environment of the coal mine and large in belt changing difficulty, and therefore the work of changing the rubber belts needs to invest a large amount of manpower and material resources and has large risks in the belt changing process.
The existing adhesive tape replacing method is generally that an adhesive tape replacing device is transported to a mine underground and then fixedly arranged below a machine head driving roller of a belt conveyor for replacing an adhesive tape, then an old tape is broken, a new tape conveyed by the adhesive tape replacing device for conveying the new tape is connected to one end of the old tape, the other end of the old tape is pulled back to be coiled and recovered by the adhesive tape replacing device for recovering the old tape, and the adhesive tape is replaced by a mode that the old tape pulls the new tape to be laid. The prior adhesive tape replacing device for clamping and conveying the adhesive tape has the following defects:
1. in order to realize stable traction, a positioning and mounting position of the adhesive tape replacing device needs to be additionally arranged under a mine, however, the working condition environment of the underground mine is complex, and particularly for over kilometer mines, the transportation and the positioning and mounting of the adhesive tape replacing device are relatively difficult;
2. for an ultra-long distance belt conveyor, if the power of the adhesive tape replacing device is not matched, the clamping force for clamping the adhesive tape is often insufficient or the traction force for pulling the adhesive tape is insufficient, so that the adhesive tape is slipped or pulled, and therefore the adhesive tape replacing device with enough high power needs to be matched, the volume and the weight of the adhesive tape replacing device are increased invisibly, and the transportation, the positioning and the installation are more difficult;
3. in order to facilitate transportation and positioning installation, the adhesive tape replacing device for conveying the new tape and the adhesive tape replacing device for recovering the old tape are usually respectively arranged and respectively positioned and installed, so that the situation that the speed of the new adhesive tape is unmatched with that of the old adhesive tape is easily caused to occur, and the laying quality of the new conveyor belt is poor or the tape replacing time is increased.
