Abstract
The electric capstan consists of DC permanent magnet motor, shaft coupler, hexagonal transmission rod, planetary speed varying mechanism, drum, steel cable and other parts. The electric capstan has the advantages that the reliable automatic load brake mechanism is designed in the roller, when the motor is powered off, the condition that the pulled heavy object does not move in the opposite direction can be ensured, and the electric capstan is reliable and safe in work. The utility model discloses the structure is exquisite, and the material is advanced, extensively is fit for installing on various types of cars.
Description
The utility model relates to a kind of electric capstan, is mainly used on the various automobile.
The various automobile that uses generally all is not equipped with electric capstan on the car now.But in the middle of reality was used, can run into various situations unavoidably needed towage, rescues and comprise that the field saves oneself or the like.If be furnished with electric capstan on the car, will bring many convenience.For Electirc capstan for vehicles, that cube is little, power is big, low voltage, big electric current, operation control is simple and reliable, and after the motor dead electricity, is pulled weight and does not move to reversing sense.
The purpose of this utility model just provides a kind of customized design, has failure-free automatic load braking mechanism, is suitable for automobile-used electric capstan.
Technical solutions of the utility model are as follows: Electirc capstan for vehicles partly is made up of direct current hydromagnetic motor, coupler, hexagonal drive link, planet speed change mechanism, cylinder and steel rope etc., wherein motor is the dc permanent magnet motor of small size, low voltage, big electric current, and adopts the end commutator structure.This capstan winch in the cylinder indoor design automatic load braking mechanism, a circumferential ring expander promptly is housed on the hexagonal drive link, one end and drive link are fixed, two semi-round bearing shells clamp spring coil and be loaded in the cylinder; Three card bases of coupler are inserted in respectively between the card base of drive link driving chip and another permanent seat of spring.
During work, direct current permanent magnet motor drives the hexagonal drive link by coupler and rotates, and moment of torsion is sent in the planetary transmission, by the third-level planetary speed change moment of torsion that has increased is sent to cylinder, and cylinder rotates and drive steel rope to reach the purpose of traction weight.After the motor dead electricity, be pulled weight and do counter motion, the torsion spring locking bearing shell that promptly can bulge is realized self-actuating brake.
Owing to adopt technique scheme, the end face commutator segment gauge H of this capstan winch propulsion source---motor can arbitrarily increase, be not subjected to the restriction of motor rotor diameter dimension, and brush is cooperated with the commutator segment plane, and the section that conducts electricity like this increases, and contact resistance reduces, overcome the used circumferential commutator of common electrical capstan winch easily overheated and fatal shortcoming of damaging in the direct current reversing process, and assembling is more prone to, and it can be suitable for automobile-used with low voltage, big current work.Motor can be controlled the realization forward and reverse easily.After the motor dead electricity,, can guarantee to be pulled weight not to the reversing sense motion, so reliable operation safety by the effect of automatic load braking mechanism.The utility model delicate structure, convenient and practical, be fit to be installed on various types of automobiles.
Be further described below in conjunction with drawings and Examples.
Fig. 1 is the used motor end face of a utility model commutator structure scheme drawing.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the utility model automatic load braking mechanism part-structure scheme drawing.
Fig. 4 is that the A-A of Fig. 3 is to cutaway view.
Among the figure: 1, commutator seat 2, commutator segment 3, brush contact surface 4, hexagonal transmission shaft 5, circumferential ring expander 6, spring fixed seat 7, driving chip 8, coupler
Embodiment as shown in the figure, one circumferential ring expander (5) is arranged on the hexagonal drive link (4), one end and drive link are fixed, and two bearing shells clamp spring coil and be loaded in the cylinder, and (8) three card bases of coupler are inserted in respectively between the card base of drive link driving chip (7) and another permanent seat of spring (6).
The electric capstan initial torque is from direct current permanent magnet motor, and coupler (8) connects motor output shaft and hexagonal drive link.When coupler (8) clockwise direction rotates, drive tripod driving chip (7) and rotate, thereby drive hexagonal drive link (4), this moment, spring was inoperative; During coupler (8) anticlockwise motion, drive spring fixed seat (6) and rotate, spring is screwed, external diameter diminishes, and makes it to break away from bearing shell, drives the hexagonal drive link then and rotates together.After the motor dead electricity, weight is if move to reversing sense, then steel rope drives cylinder, cylinder drives planet speed change mechanism, drive hexagonal drive link (4) at last towards anticlockwise motion, the moment of torsion of generation makes spring expansion, external diameter become big, and swelling is loaded on the bearing shell in the cylinder, relative motion does not take place in locking mutually under the friction force effect, realizes the capstan winch self-actuating brake.
