The invention creatively provides an integral four-shaft chain transmission direct current boring winch. The integral four-shaft chain transmission direct current boring winch comprises an input shaft, an intermediate shaft, an automatic drill feeding shaft and a roller shaft assembly which is provided with a winch roller. The roller shaft assembly is provided with a low-speed clutch and a high-speed clutch. A brake mechanism is arranged on the intermediate shaft of the winch. A low-speed end is connected with the intermediate shaft through a chain wheel mechanism large in transmission ratio. A high-speed end is connected with the intermediate shaft through a chain wheel mechanism small in transmission ratio. The high-speed end of the roller shaft is connected with an automatic drill feeding short shaft through the corresponding chain wheel mechanism. The automatic drill feeding short shaft is connected with a small-power alternating current variable frequency motor speed reducer through an automatic drill feeding clutch. The intermediate shaft is provided with a pneumatic gear shifting mechanism. The intermediate shaft is connected with the input shaft through another two chain wheel mechanisms. Motors are arranged at the two ends of the input shaft respectively. The winch is compact in structure, small in appearance size, capable of achieving independent prizing and convenient to install; and fast field installing can be rapidly achieved through the integral modularization design, and the intelligent well drilling function is achieved.
