Abstract
The utility model discloses a towing winch with bidirectional screws. The towing winch comprises a drum. A brake strap is arranged on the outer side of the drum, a jacking device is arranged below the brake strap and comprises a first support, a pulley is arranged on the first support, a draw bar of the brake strap comprises connecting portions on two sides of the draw bar, a second screw hole and a third screw hole are formed in the two connecting portions, a thread direction of the second screw hole is opposite to a thread direction of the third screw hole, a third screw is arranged in the second screw hole and the third screw hole, and thread directions of two edges of the third screw are opposite to each other. The towing winch has the advantages that the lower side of the brake strap can be in contact with the jacking device when the brake strap needs to be loosened, so that the upper side of the brake strap can be quickly separated from the drum, and the problem that the upper side of an existing brake strap clings to an existing drum due to the influence of the gravity of the existing brake strap and is separated from the drum difficultly can be solved; friction between the jacking device and the brake strap can be reduced owing to the pulley, abrasion can be decreased, the length of the draw bar can be adjusted via the third screw, and accordingly installation requirements of the brake strap can be assuredly met; the draw bar can be shortened, so that the purpose of quickly braking the towing winch can be achieved after the towing winch is used for a long time.
Description
Technical field
The utility model relates to a kind of marine equipment, particularly a kind of towing winch, specifically a kind of towing winch with reverse-flighted screw.
Background technology
Towing winch is a kind of marine equipment, in 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 conventionally, 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 drive the tension of brake band and unclamp by the flexible of hydraulic actuating cylinder, after the long-time use of brake band, the screen resilience variation of brake band, in the time that 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.
The production precision out of reach designing requirement of general brake band, or brake band is long-term use after because of reason out of reach operatings needs such as wearing and tearing, can make brake band brake speed slow.
Summary of the invention
The utility model, for prior art deficiency, provides a kind of towing winch with reverse-flighted screw, and this towing winch still can unclamp cylinder by fast speed at the long-time wire wheel back-braking structure that uses, and can Quick brake in the time of brake.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of towing winch with reverse-flighted screw, 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, be provided with pulley, the pull bar of described brake band comprises the connecting portion of both sides, on two described connecting portions, be provided with the second screw that relative hand of spiral is contrary, the 3rd screw, in described the second screw and the 3rd screw, be provided with the 3rd screw rod, the hand of spiral on described the 3rd screw rod both sides is contrary.In the time that brake band will unclamp brake band below can encounter jacking system make brake band above can depart from cylinder soon, prevent from being difficult to depart from because self gravitation impact makes brake band top be close to cylinder, pulley is set and reduces the friction between jacking system and brake band, reduce wear, length that can adjusting yoke by the 3rd screw rod, thereby guarantee the installation requirement of brake band, after long-term practicality, can reach by shortening the length of pull bar the object of Quick brake.
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 is set makes 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, on described the first support, be provided with through hole, described pulley is connected with the first screw rod, and described the first screw rod is inserted in described through hole, is respectively provided with a nut on the first screw rod of described through hole both sides.Adopt this structure that the height of pulley can be regulated, 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.The height of jacking block can be regulated.
The utility model compared with prior art, there is following beneficial effect: the utility model in the time that brake band will unclamp brake band below can encounter jacking system make brake band above can depart from cylinder soon, prevent from being difficult to depart from because self gravitation impact makes brake band top be close to cylinder, pulley is set and reduces the friction between jacking system and brake band, reduce wear, length that can adjusting yoke by the 3rd screw rod, thereby guarantee the installation requirement of brake band, after long-term practicality, can reach by shortening the length of pull bar the object of Quick brake.
