The invention discloses a hoisting machine for cable production, which has the following working principle: firstly, the lifting moving component is moved to be right above the cable tray 3, then the lifting motor 102 is controlled, the output shaft of the lifting motor 102 controls the winding shaft 103 to rotate, the winding shaft 103 releases the cable, the telescopic rod 108 moves downwards along with the clamping component under the action of gravity until the telescopic rod moves to be above the cable tray 3 (the position shown in fig. 6 and 7), then the electromagnet 215 is started, the electromagnet 215 is adsorbed on the cable tray 3 (the cable tray 3 with a reinforcing frame or the cable tray 3 made of pure iron), the lifting motor 102 is controlled, then the cable is retracted through the cable tray 3 (the clamping component is lifted), at this time, the electromagnet 215 does not move along with the clamping component because the electromagnet 215 is adsorbed with the cable tray 3, at this time, the C-shaped frame 214 does not move along with the sliding shaft pin 212, the C-shaped frame 214 is fixedly connected, so that the sliding shaft pin 212 does not move, the sliding shaft pin 212 and the swing arm bracket 210 slide relatively, so that the swing arms 209 on two sides swing, the swing arms 209 drive the insertion pull rod 218 to slide on the C-shaped frame 214 (at the moment, the second reset spring 219 compresses), so that the insertion pull rod 218 is inserted into two sides of the central shaft of the cable drum 3, then the clamping assembly continues to move upwards, and since the magnetic attraction friction force between the electromagnet 215 and the cable drum 3 is far smaller than the gravity force of the cable drum 3 (but greater than the elastic force of the two second reset springs 219), the electromagnet 215 slides relatively with the cable drum 3, at the moment, the insertion pull rod 218 lifts the cable drum 3, so that the cable drum 3 and the insertion pull rod 218 have an axial friction force, at the moment, the insertion pull rod 218 does not move, then the electromagnet 215 stops, the cable drum 3 is moved to the desired position (on the truck). If the position of the cable drum 3 needs to be rotated, the adjusting motor 202 needs to be controlled, the output shaft of the adjusting motor 202 drives the input shaft of the adjusting gearbox 203 to rotate, the input shaft of the adjusting gearbox 203 drives the adjusting driving gear 204 to rotate, the adjusting driving gear 204 rotates and drives the adjusting driven gear 205 to rotate, the adjusting driven gear 205 rotates and drives the adjusting rotating rod 206 to rotate, the rotating rod 206 rotates and drives the rotating frame 208 to rotate, the rotating frame 208 rotates and then drives the cable drum 3 to rotate, and at the moment, the placing position angle of the cable drum 3 can be adjusted.

When the clamping assembly moves vertically, the pulling motor 102 is controlled to rotate, the output shaft of the pulling motor 102 controls the winding shaft 103 to rotate, the winding shaft 103 winds up the rope, at the moment, the telescopic rod 108 moves upwards along with the clamping assembly (the clamping platform 201 is driven to move through the pulley block 106), the telescopic rod 108 slides in the telescopic sleeve 107, the telescopic rod 108 moves upwards, a steel rope connected between the winding protection disc 104 and the telescopic rod 108 is wound on the winding protection disc 104, because the torsion spring 5 is arranged in the winding protection disc 104 (the center of the torsion spring 5 is fixedly connected with the rotary connecting shaft 111, the outer ring of the torsion spring 5 is fixedly connected with the winding protection disc 104), the torsion spring 5 is reversed, and when the telescopic rod 108 moves downwards (through controlling the rotation of the pulling motor 102), the steel rope pulls the winding protection disc 104 to rotate (the elasticity of the torsion spring 5 in overcoming the winding protection disc 104, and the elasticity of the torsion spring 5 is far smaller than the gravity of the clamping assembly, so that the elasticity of the torsion spring is only used for winding the steel rope on the winding protection disc 104). When assembly pulley 106 damages, telescopic link 108 can descend fast to drive the reel protection dish 104 through the steel cable and rotate fast, the spring bolt also can rotate fast this moment, and the spring bolt can outwards throw away under the effect of centrifugal force this moment, makes the spring bolt get into the indent inslot, and hooks with the barb that sets up in the indent inslot, and reel protection dish 104 will stop rotating this moment, thereby makes cable dish 3 no longer fall down, has guaranteed the security of construction. When ambient temperature is high, the inside temperature of protection locking dish risees, and inside air begins to expand, and then leads to piston 115 to slide in adaptation pipe 113, establishes the inside sealed state that is to the protection locking dish, can reduce the influence of dust to the spring bolt, guarantees the security.
