Further, described driving shaft is provided with stop collar, and stop collar is between worm-gear speed reducer and driving wheel.
The electronic pre-tightening apparatus of quiet lotus tension tester of the present invention comprises frame and trailer, the steelframe car body of frame is provided with worm-gear speed reducer, and worm-gear speed reducer drives driving wheel to rotate by driving shaft, is moved by motor driving-trailer, remove the trouble of Manual-pushing coaster from, save manpower.Work tool to be tested is connected between quiet lotus tension tester and the trailer of pre-tightening apparatus, by control motor and just changing or the driving-trailer that reverses movable in frame, for Work tool to be tested provides pretightning force, after reaching pretightning force, pre-tightening apparatus trailer and frame are fixed, opening quiet lotus tension tester is that test Work tool arrives predetermined pressure and keeps, and reaches the object of quiet lotus tensile test.
Further, also comprise telechiric device, frequency converter and remote control module, transmitted control signal to remote control module by telechiric device, remote control module control frequency converter works, and then controlling worm-gear speed reducer work, staff does not need Non-follow control machine operation, convenient by remote control system.
The present invention compares existing coaster and also has the following advantages:
One is change test pulley structure, reduces the deadweight of test coaster, reduces the friction force with rail.The cutting of coaster redundance will be tested remove, again weld.
Two is change test coaster wheel, solves test coaster bite phenomenon, test coaster steamboat is replaced by bull wheel.
Three is installing remote devices, realizes telechiric device operation, thoroughly solves pretensioning operation Problems existing.
Four is that staff 1 people just can rely on telechiric device to carry out pretensioning operation, and the staff originally participating in test is also reduced to present 2 by original 4, raises labour productivity.
