During the actual use, utilize this belt conveyors to carry out the process of moving formula continuous belt from: firstly, detecting the distance between the crawler-type mobile trolley 1 and the tunneling equipment 4 in real time by using a laser range finder 13, transmitting the measured distance between the crawler-type mobile trolley 1 and the tunneling equipment 4 to a controller 14, and when the measured distance between the crawler-type mobile trolley 1 and the tunneling equipment 4 is larger than a set distance, controlling the walking speed of a walking crawler 1-4 of the crawler-type mobile trolley 1 to be increased by the controller 14 so as to enable the distance between the crawler-type mobile trolley 1 and the tunneling equipment 4 to be equal to the set distance; when the measured distance between the crawler-type moving trolley 1 and the tunneling equipment 4 is smaller than the set distance, the controller 14 controls the walking speed of the walking crawler 1-4 of the crawler-type moving trolley 1 to be reduced, so that the distance between the crawler-type moving trolley 1 and the tunneling equipment 4 is equal to the set distance; the assembling device 2 and the crawler-type moving trolley 1 synchronously move forwards under the driving of the crawler-type moving trolley 1;
secondly, under the pulling of the crawler-type mobile trolley 1, the belt 8 in the belt storage bin 5 has a tendency of expanding along the tunneling direction of the tunneling device 4, and when the tension sensor 16 detects that the tension applied to the belt 8 reaches a tension set value, the belt releasing mechanism in the belt storage bin 5 starts to move, so that the belt 8 expands along the tunneling direction of the tunneling device 4;
then, when the multi-turn absolute encoder 15 detects that the advancing stroke of the crawler-type moving trolley 1 is equal to the set stroke in real time, a vertical carrier roller support is installed on the first assembling mechanism, a transverse carrier roller support is installed on the second assembling mechanism, a first proximity switch 17-1 used for detecting whether the vertical carrier roller support is installed in place is installed on the first assembling mechanism, and a second proximity switch 17-2 used for detecting whether the transverse carrier roller support is installed in place is installed on the second assembling mechanism;
then, the controller 14 controls the first assembling mechanism to drive the vertical carrier roller support to move to the position right below the loose edge of the belt 8, and the controller 14 controls the second assembling mechanism to drive the transverse carrier roller support to move to the position right below the loose edge of the belt 8; then, the controller 14 controls the second assembling mechanism to drive the transverse carrier roller support and the vertical carrier roller support to be assembled; then, the controller 14 controls the second assembling mechanism to drive the carrier roller support frame to be assembled with the carrier roller support frame positioned in the previous stroke;
and finally, continuously circulating the steps one to four for multiple times to realize the continuous conveying of the belt 8 until the tunneling equipment 4 stops tunneling.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
