The technical scheme of the utility model is as follows:
a clutch structure of a heavy cable rack is characterized in that 2 strip-shaped supports are connected into a rectangle through a telescopic shaft; each strip-shaped support is provided with a fixed support and a movable support; the fixed support is provided with a driving roller, the movable support is provided with a driven roller, and the cable shaft disc is lapped between the driving roller and the driven roller; the servo motor is connected with a gearbox, and an output shaft of the gearbox coaxially rotates with the T-shaped shaft; the disc of the T-shaped shaft is provided with a first through hole, and the outer side of the cylindrical shaft of the T-shaped shaft is provided with threads; the driving gear is arranged on the cylindrical shaft, and a second through hole corresponding to the first through hole is formed in the fluted disc of the driving gear; the gland is provided with a through hole and is sleeved on the cylindrical shaft in a penetrating way; the nut is screwed on the screw thread, and a reset spring is arranged between the nut and the gland; a shifting fork is embedded between the gland and the driving gear, the horizontal section of the shifting fork is semicircular, the vertical section of the shifting fork is trapezoidal, and the upper part is wide and the lower part is narrow; the shifting fork is connected with the spanner; a clutch rod is fixed on one side of the gland close to the driving gear, and a rod body of the clutch rod penetrates into the first through hole and the second through hole;
the driving gear is meshed with the driven gear, and the driven gear and the driving roller coaxially rotate.
The number of the first through holes, the second through holes and the clutch rods is multiple.
A gasket is arranged between the nut and the reset spring.
The outer edges of the driving roller and the driven roller are provided with protruding parts, and the cable shaft disc is embedded between the protruding parts.
The servo motor and the gearbox are of an integral structure and are fixed on one side of the fixed support.
The utility model has the advantages that: the handle is used for driving the shifting fork to be embedded between the gland and the driving gear, and the inclined surface of the shifting fork can push the gland to axially move so as to drive the clutch rod to enter and exit from the first through hole, thereby forming a clutch effect. Thus, a clutch action can be formed. The utility model can meet the requirements of construction sites, and has simple structure, safety and reliability.
