The present invention discloses a kind of towing winch with brake structure, comprises cylinder, and described cylinder arranged outside has brake band, is provided with jack-up device below described brake band, and described jack-up device comprises the first support, and described first support is provided with pulley. When brake band to be unclamped, the lower section of brake band can be encountered jack-up device and made to depart from cylinder soon above brake band, prevent from making above brake band, to be close to cylinder due to self gravitation impact to be difficult to depart from, pulley is set and reduces the friction between jack-up device and brake band, reduce wear.

Description

A kind of towing winch with brake structure
Technical field
The present invention relates to a kind of ship's machinery, in particular to a kind of towing winch, specifically a kind of towing winch with brake structure.
Background technology
Towing winch is a kind of ship's machinery, uses when ship is hauled, and general towing winch comprises oil motor, cylinder, bus cable device and drift stop. Brake device of winch mainly plays effect fixing, release boats and ships hawser.
The drift stop of existing winch is generally brake band, and the operation of existing brake band generally all relies on manpower strain and discharge cylinder. There is following problem in this kind of structure: brake is by manual operation, the braking to cylinder is realized by the strength of the speed of artificial hand screw rod and workman, the size of workman's strength and the speed of hand screw rod are generally not capable of the working condition requirement of satisfied big load ship machinery, and workman's danger when hand screw rod is very big, it is easy to cause security incident.
In order to improve security and adapt to the braking of large-scale winch, the brake band of a lot of large-scale winch all adopts hydro-cylinder to drive, generally driven the tension of brake band by the flexible of hydro-cylinder and unclamped, after brake band uses for a long time, the screen resilience of brake band is deteriorated, when brake band unclamps, due to brake band self gravitation effect, cylinder has been unclamped in the lower section of brake band, and the top of brake band still holds cylinder tightly so that cylinder is difficult to rotate.
Summary of the invention
The present invention is directed to prior art deficiency, a kind of towing winch with brake structure is provided, this kind of towing winch after a long time use brake structure still can reach the requirement of normal operation, stop tight and unclamp the requirement that can reach design, reduce unnecessary brake shelling to damage, 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, jack-up device it is provided with below described brake band, described jack-up device comprises the first support, and described first support is provided with pulley. When brake band to be unclamped, the lower section of brake band can be encountered jack-up device and made to depart from cylinder soon above brake band, prevent from making above brake band, to be close to cylinder due to self gravitation impact to be difficult to depart from, pulley is set and reduces the friction between jack-up device and brake band, reduce wear.
In technique scheme, it is preferable that, described jack-up device also includes the 2nd support, and described 2nd pedestal upper end is provided with top block. Arrange when top block makes brake band jack-up more reliable and stable. Top block is set also for by brake band jack-up, and coordinates with pulley and make it more to stablize.
In technique scheme, it is preferable that, described first support is provided with through hole, described pulley is connected with the first screw rod, and described first screw rod is inserted in described through hole, and the first screw rod of described through hole both sides is respectively provided with a nut. Adopt this kind of structure that the height of pulley can be regulated, rotate the height to pulley by two nuts and regulate.
In technique scheme, it is preferable that, the straight line at described first screw rod place is through the rotating shaft of described cylinder. Make the jack-up better effects if of jack-up device like this
In technique scheme, it is preferable that, described 2nd pedestal upper end is provided with the 2nd screw rod, and block bottom, described top is provided with the first screw, and described first screw coordinates with described 2nd screw rod. The height pushing up block can be regulated.
The present invention is compared with prior art, there is following useful effect: the lower section of the present invention's brake band when brake band to be unclamped can be encountered jack-up device and be made to depart from cylinder soon above brake band, prevent from making above brake band, to be close to cylinder due to self gravitation impact to be difficult to depart from, pulley is set and reduces the friction between jack-up device and brake band, reduce wear.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of the first support.
Fig. 3 is the structural representation of the 2nd support.
Fig. 4 is the partial enlargement figure of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: see 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, it is provided with jack-up device 3 below described brake band 2, described jack-up device 3 comprises the first support 4, and described first support 4 is provided with pulley 41. When brake band 2 to be unclamped, the lower section of brake band 2 can be encountered jack-up device 3 and made to depart from cylinder 1 soon above brake band 2, prevent from making above brake band 2, to be close to cylinder 1 due to self gravitation impact to be difficult to depart from, pulley 41 is set and reduces the friction between jack-up device 3 and brake band 2, reduce wear.
Described jack-up device 3 also includes the 2nd support 5, and described 2nd support 5 upper end is provided with top block 51. Arrange when top block 51 makes brake band 2 jack-up more reliable and stable. Top block 51 is set also for by brake band 2 jack-up, and coordinates with pulley 41 and make it more to stablize.
Being provided with through hole 42 on described first support 4, described pulley 41 is connected with the first screw rod 43, and described first screw rod 43 is inserted in described through hole 42, and the first screw rod 43 of described through hole 42 both sides is respectively provided with a nut 44. Adopt this kind of structure that the height of pulley 41 can be regulated, rotate the height to pulley 41 by two nuts 44 and regulate.
The straight line at described first screw rod 43 place is through the rotating shaft of described cylinder 1. Make the jack-up better effects if of jack-up device 3 like this
Described 2nd support 5 upper end is provided with the 2nd screw rod 52, and block 51 bottom, described top is provided with the first screw 53, and described first screw 53 coordinates with described 2nd screw rod 52. The height pushing up block 51 can be regulated.
Owing to the production precision of brake band 2 does not reach design requirements, or because the reasons such as abrasion do not reach service requirements after brake band 2 life-time service, this just needs the degree of tightness to brake band 2 to regulate, therefore in the present embodiment, the pull bar 21 of described brake band 2 comprises the connection section 22 of both sides, two described connection sections 22 are provided with the 2nd screw 23 that relative screw thread direction is contrary, 3rd screw 24, it is provided with the 3rd screw rod 25 in described 2nd screw 23 and the 3rd screw 24, the screw thread direction on described 3rd screw rod 25 both sides is contrary, the stretch into amount of the 3rd screw rod 25 in connection section 22 can be regulated by rotating the 3rd screw rod 25, realize the adjustment of pull bar 21 length, so that brake band 2 degree of tightness can regulate. 3rd screw rod 25 is fixedly connected with the hex-nut 26 facilitating the 3rd screw rod 25 to rotate.
