Description
Technical field
The utility model belongs to the mechanical lifting equipment technical field, relates to the locking latching device of a kind of band brake.
Background technology
The mechanical lifting winch in the oil field, sector applications such as mine, geological mapping, harbour, building are quite extensive, and the winch brake system is the key equipment of winch, therefore guarantees that the braking reliability of winch brake system is very important.And the advantage that band brake is big with braking torque, simple structure is compact receives much concern.Traditional band brake all is to hold brake drum tightly with the push pull maneuver drive brake steel band and the brake shoes of oil cylinder, yet, under the situation of long-term immobilization; Repeated use along with brake; Brake shoes can wear and tear, so the drag position can take place to change slowly, and oil cylinder hydraulic oil takes place is slowly easily revealed in addition; Oil cylinder piston bar counteragent causes brake weight to reduce gradually even lost efficacy; Cause potential safety hazard, be necessary that therefore the braking mechanism after the braking is carried out locking locking to be handled, and guarantees drag reliably and with long-term.
Summary of the invention
The purpose of the utility model provides the locking latching device of a kind of band brake, has solved prior art under the situation of long-term immobilization, and oil cylinder exists hydraulic oil to reveal the problem that causes brake weight to reduce gradually even lost efficacy.
The technical scheme that the utility model adopted is, the locking latching device of a kind of band brake comprises locking lock portion and screw mechanism two parts,
Described locking lock portion comprises the lever connecting plate, and the lever connecting plate is fixed with brake axle, and brake axle is connected with connecting rod through bearing pin B; The lever connecting plate is crossed otic placode and is connected with brake band; The lever connecting plate is also hinged with the oil cylinder piston bar;
Described screw mechanism comprises nut A, and nut A is connected through bearing pin A with connecting rod, and nut A axes sleeve is equipped with screw rod, in the termination handwheel is installed after the screw rod upper end passes support; Handwheel is captiveed joint with screw rod, and nut B and spring shim captive joint are passed through after passing nut A in the screw rod lower end.
The beneficial effect of the utility model is; Utilize lever principle; Convert the straight-line motion of brake oil cylinder into brake axle rotatablely move through the lever connecting plate; Because brake axle is captiveed joint with connecting rod through bearing pin B, the connecting rod other end and overlaps screw mechanism and is connected by bearing pin A, so the rotatablely moving and be converted into the straight-line motion of screw mechanism of brake axle; And then make connecting rod, brake axle and lever connecting plate remain on locked position for a long time by the screw thread interlocking principle between a pair of nut; The piston rod that has effectively stoped the oil cylinder draining to cause oppositely moves, and has solved the problem of brake degradation failure, is widely used in multiple rotary lifting equipment such as winch, windlass, capstan winch, winch.
Description of drawings
Fig. 1 is the locking lock portion of the utility model and the scheme drawing that is connected of brake band;
Fig. 2 is the screw mechanism structure for amplifying scheme drawing of the utility model device.
Among the figure, 1. connecting rod, 2. nut A, 3. bearing pin A, 4. screw rod, 5. support, 6. spacer; 7. handwheel, 8. screw, 9. pressing plate, 10. nut B, 11. spring shims, 12. lever connecting plates, 13. brake axles; 14. bearing pin B, 15. brake bands, 16. otic placodes, 17. oil cylinder piston bars, 18. binding face A, 19. binding face B.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
Like Fig. 1, shown in Figure 2; The mechanical type brake locking device of the utility model comprises locking lock portion and screw mechanism two parts, and locking lock portion comprises lever connecting plate 12; Lever connecting plate 12 is fixed with brake axle 13, and brake axle 13 is connected with connecting rod 1 through bearing pin B14; Lever connecting plate 12 is connected with brake band 15 through otic placode 16; Lever connecting plate 12 is also hinged with oil cylinder piston bar 17;
Screw mechanism comprises nut A2, and nut A2 is connected through bearing pin A3 with connecting rod 1, and nut A2 axes sleeve is equipped with screw rod 4, and screw rod 4 upper ends pass support 5 backs handwheel 7 is installed in the termination; Handwheel 7 is captiveed joint with screw rod 4 through screw 8 and pressing plate 9, and nut B10 and spring shim 11 captive joints are passed through after passing nut A2 in screw rod 4 lower ends.Handwheel 7 is binding face A18 with the contact surface of spacer 6, and spring shim 11 is binding face B19 with the contact surface of nut A2.
Be connected through screw 8 between handwheel 7 and the screw rod 4, also can adopt other connection modes or be made of one.
The utility model device principle of work is, 12 two ends of lever connecting plate are connected through bearing pin with brake band 15 and oil cylinder piston bar 17 respectively, and lever connecting plate 12 is the integral type welded structure with brake axle 13; The hydraulic circuit fuel feeding, oil cylinder piston bar 17 retractions drive lever connecting plate 12 and 13 while of brake axle left-hand revolution, and drop-down brake band is held brake hub tightly and is realized drag.Because connecting rod 1 is connected by bearing pin B14 with brake axle 13, so left-hand revolution also can take place in connecting rod 1 under brake axle 13 drives.This moment is as shown in Figure 2, and connecting rod 1 is connected through bearing pin A3 with nut A2, and nut A2 and screw rod 4 are for being threaded; Therefore the rotatablely moving and be converted into nut A2 and drive the straight-line motion that screw rod 4 moves on the whole and breaks away of connecting rod 1, causes screws 4 breaks away from binding face A18 place with spacer 6, and this moment need turn handwheel 7; Screw rod is threaded to for 4 times with spacer 6 fits again; Can make nut A2 and spring shim 11 break away from like this, only need turn nut B10, make spring shim 11 be fitted in nut A2 bottom again at binding face B19 place; Realized the double nuts interlocking; Keep connecting rod 1, brake axle 13, lever connecting plate 12 to be in normal danger for a long time, oppositely move, guarantee that brake is permanently effective thereby limited the piston rod that the oil cylinder draining causes.
The utility model device utilizes lever principle; Convert the straight-line motion of brake oil cylinder into brake axle 13 rotatablely move through lever connecting plate 12; Because brake axle 13 is captiveed joint with connecting rod 1 through bearing pin B14; Connecting rod 1 other end and a cover screw mechanism are connected by bearing pin A3, so the rotatablely moving and be converted into the straight-line motion of screw mechanism of brake axle 13, and then make connecting rod 1, brake axle 13 and lever connecting plate 12 remain on locked position for a long time by the screw thread interlocking principle between a pair of nut; The position of nut on screw rod can be adjusted according to the change of braking position; Easy to use, effectively stoped the oil cylinder piston bar because hydraulic oil is revealed the counteragent that causes, solved the problem of brake degradation failure.
