Hydraulic windlass mainly is made up of planetary reduction gear, drg, reel, HM Hydraulic Motor etc.Owing to adopt floating type planetary reduction gear, make running more steady, more reasonable structure adopts the multiple-piece friction brake, and lock torque is big, and is safe and reliable.Therefore, product has characteristics such as volume is little, compact conformation, driving efficiency height.But it still has following deficiency: HM Hydraulic Motor can only drive the reel rotation by the two-stage planetary transmission, and promptly reel can only be realized a kind of rotating speed, and this moment, transmitting ratio was bigger, and drum speed is lower, and pulling force is bigger.Therefore this hydraulic windlass can only be applicable to the drum speed requirement lowlyer, and pulling force requires bigger occasion.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of dual-speed hydraulic capstan winch that can realize that double speed rotates is provided.
The purpose of this utility model is achieved in that a kind of dual-speed hydraulic capstan winch, comprise first support, second support, the hydraulic pressure horse, drg, transmission shaft, the one-level sun gear, primary planet pinion, primary planet carrier, gear ring, secondary sun gear, secondary planetary gear, the secondary planet frame, reel, pull bar and gear shifting handle, described HM Hydraulic Motor is arranged on first support, HM Hydraulic Motor links to each other with drg, drg links to each other with an end of transmission shaft, the one-level sun gear is installed on the transmission shaft, one-level sun gear and primary planet pinion engagement, primary planet pinion is installed on the primary planet carrier, primary planet pinion and gear ring engagement, primary planet carrier connects with secondary sun gear by spline simultaneously, secondary sun gear and secondary planetary gear engagement, secondary sun gear is by spline and propeller shaft couplings simultaneously, secondary planetary gear is installed on the secondary planet frame, the secondary planet frame is fixedly mounted on second support, secondary planet frame and gear ring engagement, gear ring is captiveed joint with reel by bolt, one end of pull bar is connected with secondary sun gear, and gear shifting handle is installed in the other end of pull bar.
The beneficial effects of the utility model are:
Reel of the present utility model can be realized two kinds of rotating speed outputs: a kind of is that HM Hydraulic Motor is passed through the rotation of two-stage planetary transmission driving reel, this moment, transmitting ratio was bigger, and drum speed is lower, and pulling force is bigger, be applicable to the drum speed requirement lowlyer, pulling force requires bigger occasion; Another kind is that HM Hydraulic Motor is only passed through the secondary planetary gear transmission, drives the reel rotation, and this moment, transmitting ratio was smaller, and drum speed is higher, and pulling force is less, is applicable to drum speed is had relatively high expectations the occasion that pulling force is less.
