Abstract
The utility model belongs to the technical field of a crane, and particularly relates to a sealed built-in shackle hook for the crane. The box body of a lifting hook is sealed; a motor and a distribution box are arranged at two inner ends of the sealed box body; the motor is connected with a friction torque limiter; the friction torque limiter and a pinion are assembled together, and the motor drives the friction torque limiter, thereby driving the pinion and then driving a rack wheel, so as to drive the hook to rotate. The sealed built-in shackle hook has the beneficial effects that the technical problem that the motor is damaged due to a locked-rotor is effectively solved, and the sealed built-in shackle hook has good tightness.
Description
Technical field
The utility model belongs to the hoisting crane technical field, relates in particular to a kind of hoisting crane with the built-in shackle hook of sealing.
Background technology
Prior electric shackle hook, structure are complicated, bulky, and fault rate is high; The large-tonnage shackle hook is because hoisting weight is excessive simultaneously, and when suspension hook met with obstruction, motor can be damaged because of stall; Existing shackle hook generally all uses semienclosed, and sealing property is not fine, out of doors or operating mode comparatively use under the condition of severe, switch box and motor are damaged easily.
Summary of the invention
The utility model is to above deficiency, and a kind of good seal performance, built-in shackle hook are provided.
The utility model solves the technical scheme that its technical matters adopted:
The built-in shackle hook of sealing; Form by assembly pulley, seal case, motor reducer, miniature gears, friction-type torque limiter, suspension hook assembly, switch box, big gear wheel; The casing of suspension hook is a sealed type, and motor and switch box are arranged at the inner two ends of seal case, and motor is connected with the friction-type torque limiter; Friction-type torque limiter and miniature gears are assembled together; Motor-driven friction-type torque limiter, thereby Drive pinion are done spinning movement thereby drive big gear wheel driving suspension hook again.
The beneficial effect of the utility model is:
1. simple in structure.
2. easy to use.
3. when having solved the large-tonnage shackle hook effectively and having met with obstruction, the technical barrier that motor is damaged because of stall.
4. have better seal property, make switch box and motor obtain better protection.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the right elevation of the utility model.
Among the figure:
L, assembly pulley, 2, seal case, 3, motor reducer, 4, miniature gears, 5, the friction-type torque limiter, 6, the suspension hook assembly, 7, switch box, 8, big gear wheel.
The specific embodiment
Shown in accompanying drawing; The built-in shackle hook of sealing is made up of assembly pulley 1, seal case 2, motor reducer 3, miniature gears 4, friction-type torque limiter 5, suspension hook assembly 6, switch box 7, big gear wheel 8, and the casing of suspension hook is a sealed type; Motor and switch box 7 are arranged at the inner two ends of seal case; Motor is connected with friction-type torque limiter 5, and friction-type torque limiter 5 is assembled together motor-driven friction-type torque limiter 5 with miniature gears 4; Thereby Drive pinion 4 is done spinning movement thereby drive big gear wheel 8 driving suspension hooks again.
Claims (2)
1. seal built-in shackle hook; Form by assembly pulley, seal case, motor reducer, miniature gears, friction-type torque limiter, suspension hook assembly, switch box, big gear wheel; It is characterized in that: the casing of suspension hook is a sealed type, and motor and switch box are arranged at the inner two ends of seal case, and motor is connected with the friction-type torque limiter; Friction-type torque limiter and miniature gears are assembled together; Motor-driven friction-type torque limiter, thereby Drive pinion are done spinning movement thereby drive big gear wheel driving suspension hook again.
