The utility model is achieved through the following technical solutions:
A kind of large-tonnage four caterpillar-tractors, include column, described column is added to be provided with, cross sill, four traction wheels that being separately installed with of the aft end face of the front end face of described entablatrance and lower surface and cross sill and upper surface cooperatively interacts and tension wheel, be installed with on the crossbeam end face of the correspondence between described traction wheel and the tension wheel, sagging straight hold-down cylinder and a left side, right horizontal hold-down cylinder, be provided with vertical holder cable aligning gear between the described sagging straight hold-down cylinder, it is characterized in that: described vertical holder cable aligning gear provides power by an AC servo motor, pass through synchronous pulley, Timing Belt is given transmission shaft transmission of power, described transmission shaft both sides all are equipped with universal drive shaft and worm gear screw elevator, captive joint with push rod in the upper end of described worm gear screw elevator, described push rod moves up and down along the guide rail that is fixed on the cross sill, the motion of Indirect driven lower vertical hold-down cylinder, be distributed with respectively circular groove on described traction wheel and the tension wheel, described tension wheel is by the air cylinder driven corresponding with it.
Described traction wheel adopts separate electrical motor to drive, and is delivered to transmission shaft through synchronous belt pulley transmission, level Four change speed gear box after slowing down, and again gives four traction wheel parts transmission of power respectively by three Timing Belts, drives traction wheel from four direction and rotates.
Described up and down vertical hold-down cylinder, left and right horizontal hold-down cylinder are cylinder, and every row has 18 cylinders to promote the crawler belt clamping.
Pass through chamfered transition between the both sides of described circular groove and the traction wheel wheel face.
Its principle is: this traction machine adopts separate electrical motor to drive, and, draws simultaneously from four direction respectively thereby drive 4 crawler belts through 4 Ф 630 traction wheels rotations of reductor deceleration rear drive by the level Four change speed gear box; The traction crawler belt adopts many contracts band pattern increasing friction force.The four directions is pneumatic pinch to clamping up and down, and every row has 18 cylinders to promote the crawler belt clamping, and the thrust of crawler belt can adjust separately to compensate the deviation that cable weight causes up and down, and the tension force of 4 crawler belts is regulated by 4 cylinders.The effective length of contact of traction machine crawler belt and cable is large, can increase skin friction force, so increasing traction and can not damage cable by pressure.By at alternating-current variable frequency motor dress light code device, adopt closed loop control, motor by Siemens PLC C and color touch screen, by the PROFIBUS bus, is controlled the rotating speed of each motor by Frequency Converter Control, realizes the synchronized operation of traction electric machine and manufacturing line.
And the utility model can use separately up and down that crawler belt clamps, and this moment, its tractive force limit was 9T, the cable diameter range of use be Ф 20～Ф 155, four crawler belts when using simultaneously tractive force limit be 15T, the cable diameter range of use is Ф 155～Ф 360.
The utility model has the advantages that:
The utility model belongs to large specification, big-length, very high to the drawing tension accuracy requirement, be used for marine cable cables manufacturing specialized equipment, can satisfy the requirements at the higher level that the user proposes aspects such as separated motor synchronous control accuracy, Pneumatic Tension control accuracy, control of product precision, device security performance and reliability, the user is easy to use, and maintenance is convenient.
