Abstract

An electric tractor for a pipeline relates to an electro-mechanical device specially used for towing a deruster or a sand blaster to run on an overhauling pipeline with an erosion resistant coating. The electric tractor mainly consists of a direct current motor, a supporting wheel for the direct current motor, a main gear box, a supporting wheel for the main gear box, a rib plate base, an output transmission shaft, two traction arms, two friction wheels, two inclined strut spring regulating device and the like. The tractor adopts the direct current motor to conduct the stepless speed regulation and the bidirectional running; a traction shaft sleeve of the tractor is integrally connected with an outer sleeve of the deruster or the sand blaster through an inserted pin; the two inclined strut spring regulating devices enhance the rigidity of the tractor; meanwhile, a frictional force (between the friction wheels and the pipe walls) on two sides is approximately equal; and when one of the two friction wheels runs into a weld joint on the pipe wall to protrude during the running process of the tractor, or the two friction wheels simultaneously run into the weld joint, the automatic microadjustment of an inclined strut spring can lead the tractor to smoothly pass through. The tractor has the advantages of light weight, convenient assembly or disassembly, strong traction force, stable operation and the like.
