Abstract
The invention discloses a towing winch with a brake structure. The towing winch comprises a drum. A brake belt is arranged on the outer side of the drum, and a jacking device is arranged below the brake belt and comprises a first support with a pulley thereon. When the brake belt is loosened, the jacking device can jack the brake belt to enable the brake belt to be quickly separated from the drum, so that the problem that the brake belt is attached to the drum and hard to separate from the same due to dead weight is prevented, friction between the jacking device and the brake belt can be reduced by the pulley, and abrasion is reduced as well.
Description
Technical field
The present invention relates to a kind of marine equipment, particularly a kind of towing winch, specifically a kind of towing winch with brake structure.
Background technology
Towing winch is a kind of marine equipment, in the ship haul, uses, and general towing winch comprises HM Hydraulic Motor, cylinder, bus cable device and brake equipment.That brake device of winch mainly plays is fixing, discharge the effect of ship cable.
The brake equipment of existing winch is generally brake band, and the operation of existing brake band generally all relies on manpower to strain and discharges cylinder.There is following problem in this structure: brake is by manual operation, realize the braking to cylinder by the speed of artificial hand screw rod and workman's strength, the size of workman's strength and the speed of hand screw rod can not meet the working condition requirement of large load ship machinery usually, and workman's danger in hand screw rod is very large, easily causes safety misadventure.
In order to improve the braking of safety and the large-scale winch of adaptation, the brake band of a lot of large-scale winches all adopts hydraulic actuating cylinder to drive, generally by the flexible of hydraulic actuating cylinder, drive the tension of brake band and unclamp, after the long-time use of brake band, the screen resilience variation of brake band, when brake band unclamps, due to the effect of brake band self gravitation, cylinder has been unclamped in the below of brake band, and the top of brake band is still held cylinder tightly, makes cylinder be difficult to rotate.
Summary of the invention
The present invention is directed to the prior art deficiency, a kind of towing winch with brake structure is provided, this towing winch still can reach requiring Sha Che Brake tightly and unclamping the requirement that can reach design of normal operation at the long-time wire wheel back-braking structure that uses, reduce unnecessary brake rubber block wearing and tearing, and reduce the time of brake.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of towing winch with brake structure, comprise cylinder, described cylinder arranged outside has brake band, described brake band below is provided with jacking system, described jacking system comprises the first support, on described the first support, is provided with pulley.When brake band will unclamp brake band below can encounter jacking system make brake band above can break away from cylinder soon, prevent from being difficult to break away from because the self gravitation impact makes the brake band top be close to cylinder, pulley is set and reduces the friction between jacking system and brake band, reduce wear.
In technique scheme, preferred, described jacking system also includes the second support, and described the second support upper end is provided with jacking block.More reliable and stable when jacking block being set making brake band jack-up.Jacking block is set also for by brake band jack-up, and coordinates and make it more to stablize with pulley.
In technique scheme, preferred, be provided with through hole on described the first support, described pulley is connected with the first screw rod, and described the first screw rod is inserted in described through hole, respectively is provided with a nut on the first screw rod of described through hole both sides.Adopt this structure to make the height of pulley to regulate, by two nut rotations, the height of pulley is regulated.
In technique scheme, preferred, the straight line at described the first screw rod place is through the rotating shaft of described cylinder.Make like this jack-up better effects if of jacking system
In technique scheme, preferred, described the second support upper end is provided with the second screw rod, and described jacking block bottom is provided with the first screw, and described the first screw coordinates with described the second screw rod.Make the height of jacking block to regulate.
The present invention compared with prior art, there is following beneficial effect: when the present invention will unclamp at brake band brake band below can encounter jacking system make brake band above can break away from cylinder soon, prevent from being difficult to break away from because the self gravitation impact makes the brake band top be close to cylinder, pulley is set and reduces the friction between jacking system and brake band, reduce wear.
The accompanying drawing explanation
The structural representation that Fig. 1 is the embodiment of the present invention.
The structural representation that Fig. 2 is the first support.
The structural representation that Fig. 3 is the second support.
The partial enlarged drawing that Fig. 4 is Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail: referring to Fig. 1 to Fig. 4, a kind of towing winch with brake structure, comprise cylinder 1, described cylinder 1 arranged outside has brake band 2, described brake band 2 belows are provided with jacking system 3, described jacking system 3 comprises the first support 4, on described the first support 4, is provided with pulley 41.When brake band 2 will unclamp brake band 2 below can encounter jacking system 3 make brake band 2 above can break away from cylinder 1 soon, prevent from being difficult to break away from because the self gravitation impact makes brake band 2 tops be close to cylinder 1, the friction that pulley 41 reduces between jacking system 3 and brake band 2 is set, reduces wear.
Described jacking system 3 also includes the second support 5, and described the second support 5 upper ends are provided with jacking block 51.More reliable and stable when jacking block 51 being set making brake band 2 jack-up.Jacking block 51 is set also for by brake band 2 jack-up, and coordinates and make it more to stablize with pulley 41.
Be provided with through hole 42 on described the first support 4, described pulley 41 is connected with the first screw rod 43, and described the first screw rod 43 is inserted in described through hole 42, on the first screw rod 43 of described through hole 42 both sides, respectively is provided with a nut 44.Adopt this structure to make the height of pulley 41 to regulate, by 44 rotations of two nuts, the height of pulley 41 is regulated.
The straight line at described the first screw rod 43 places is through the rotating shaft of described cylinder 1.Make like this jack-up better effects if of jacking system 3
Described the second support 5 upper ends are provided with the second screw rod 52, and described jacking block 51 bottoms are provided with the first screw 53, and described the first screw 53 coordinates with described the second screw rod 52.Make the height of jacking block 51 to regulate.
Production precision out of reach designing requirement due to brake band 2, perhaps brake band 2 is long-term use after because of reason out of reach operatings needs such as wearing and tearing, this just need to can regulate the degree of tightness of brake band 2, therefore in the present embodiment, the pull bar 21 of described brake band 2 comprises the connecting portion 22 of both sides, be provided with the second screw 23 that relative hand of spiral is contrary on two described connecting portions 22, the 3rd screw 24, be provided with the 3rd screw rod 25 in described the second screw 23 and the 3rd screw 24, the hand of spiral on described the 3rd screw rod 25 both sides is contrary, can regulate the stretch into amount of the 3rd screw rod 25 in connecting portion 22 by rotating the 3rd screw rod 25, realize the adjusting of pull bar 21 length, thereby make brake band 2 degrees of tightness to regulate.Be fixedly connected with the hexagonal nut 26 that facilitates the 3rd screw rod 25 to rotate on the 3rd screw rod 25.
