Description
Technical field
The utility model belongs to seafari equipment technology field, relates to a kind of sampling winch with the ratchet anti-slipping mechanism.
Background technology
Exploitation method in the ocean engineering is of all kinds, but geological sample need to rise on the water surface from the stratum, seabed, and the mode that usually adopts winch to lift rises to core on the water surface deck by bleeding iron.
Existing sampling winch is to adopt hydraulic driving mode, and what the winch brake system adopted is the brake of hydraulic pressure oil-break, provides brake weight by the spring in the multiple-piece brake gear behind the oil-break.Because for a long time after the spring brake work, spring all can produce fatigue, and because long-term brake abrasion action, brake facing also can attenuation, acting force of the spring can diminish, when running into unexpected application force at sea, will cause not because of brake weight the downslide of sampling winch rope, the safety and reliability of impact sampling winch work.
Summary of the invention
The purpose of this utility model provides a kind of sampling winch with the ratchet anti-slipping mechanism, solved and taken a sample winch in the prior art after the motor brake braking, since the winch rope-lowering under accidental action power and the failure condition, the safety and reliability problem of impact sampling winch work.
The technical scheme that the utility model adopts is, a kind of sampling winch with the ratchet anti-slipping mechanism is equipped with roller bearing seat, lead screw shaft bearing and pawl base in frame,
The winch main shaft is installed in the roller bearing seat, the cylinder of winch main shaft and coaxial package connects as one, and on the side plate of cylinder ratchet is installed, and on the winch spindle end of ratchet the same side minor sprocket is installed, the winch main shaft other end is connected with drop-gear box, and drop-gear box is connected with hydraulic motor transmission;
Leading screw and feed rod are installed in the lead screw shaft bearing, and leading screw and feed rod be arranged in parallel, jointly are set with a rope winding jib on leading screw and the feed rod, coaxial handwheel and the hinge wheel of being installed with in the end of leading screw, and hinge wheel is connected by chain gear with minor sprocket;
Ratchet and hydraulic actuating cylinder are installed on the pawl base, and the ratchet tail end is hinged by bearing pin and pawl base, and ratchet is corresponding with ratchet to be placed in the vertical facade, and the ratchet middle part is hinged with the piston rod end of hydraulic actuating cylinder, and cylinder body afterbody and the pawl base of hydraulic actuating cylinder are hinged.
The beneficial effects of the utility model are, the sampling winch can be stopped temporarily and unlikely generation is glided when lifting heavy, have guaranteed the safety and reliability of sampling winch work.
Description of drawings
Fig. 1 is that the utility model is with the structural representation of the sampling winch of ratchet anti-slipping mechanism;
Fig. 2 is the A line of vision scheme drawing among Fig. 1.
Among the figure, 1. HM Hydraulic Motor, 2. drop-gear box, 3. cylinder, 4. ratchet, 5. minor sprocket, 6. handwheel, 7. hinge wheel, 8. frame, 9. rope winding jib, 10. leading screw, 11. feed rods, 12. ratchets, 13. bearing pins, 14. hydraulic actuating cylinders.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
With reference to Fig. 1, Fig. 2, the utility model is with the sampling winch of ratchet anti-slipping mechanism, and its structure is, in frame 8 roller bearing seat, lead screw shaft bearing and pawl base is installed,
The winch main shaft is installed in the roller bearing seat, the cylinder 3 of winch main shaft and coaxial package connects as one, be integrally formed the formula welded structure, by bolt ratchet 4 is installed on the side plate of cylinder 3, with on the winch spindle end of ratchet 4 the same sides minor sprocket 5 is installed, the winch main shaft other end is connected with drop-gear box 2, and drop-gear box 2 is in transmission connection with HM Hydraulic Motor 1;
Leading screw 10 and feed rod 11 are installed in the lead screw shaft bearing, leading screw 10 be arranged in parallel with feed rod 11, jointly be set with a rope winding jib 9 on leading screw 10 and the feed rod 11, rope winding jib 9 can be along realizing parallel motion on leading screw 10 and the feed rod 11, coaxial handwheel 6 and the hinge wheel 7 of being installed with in the end of leading screw 10, hinge wheel 7 and minor sprocket 5 are connected by chain gear; HM Hydraulic Motor 1 drives hinge wheel 7 rotations through 3 rotations of drop-gear box 2 deceleration rear driving drums thereby drive minor sprocket 5, and hinge wheel drives leading screw and rotates, thereby rope winding jib 9 is moved along leading screw 10 axial directions, realizes even cloth rope;
The principle of work of the utility model sampling winch is: control system control Hydraulic Pump starts and shuts down, Hydraulic Pump is to HM Hydraulic Motor 1 fuel feeding, HM Hydraulic Motor 1 rotating speed drives the winch main shaft and rotates after drop-gear box 2 slows down, cylinder 3 rotates thereupon realizes rope closing and rope stretching, steel rope transfer by overhead traveling crane guiding rear haulage sample collector or on carry, finish the recovery operation of sea-floor soil sampling and sample collector; The winch spindle speed drives rope winding jib 9 passive row's ropes after minor sprocket 5, hinge wheel 7 slow down, also can be by rotating handwheel 6 rotating threaded shafts 10, the position of realizing manual regulation rope winding jib 9; When HM Hydraulic Motor 1 running, ratchet 12 is removed from ratchet 4 under hydraulic actuating cylinder 14 piston rods promote, and when HM Hydraulic Motor 1 drag, ratchet 12 with ratchet 4 chuckings, is realized the reliable locking of cylinder 3 under the pulling of hydraulic actuating cylinder 14 internal reset springs.Winch is controlled the winch infinite speed variation by the flow of control Hydraulic Pump, stops then to adjust to the realization of " 0 " position by oil sources off-load, pumping plant shutdown or Hydraulic Pump.
Sampling winch of the present utility model, simple in structure, reliable lock, economical and practical, solved the sampling winch after the motor brake braking, because the winch rope-lowering problem that accidental action power causes can be widely used on all kinds of prospecting ships.
