Description
Technical field
The present invention relates to a kind of draw gear, particularly a kind of steel rope straight line draw gear.
Background technology
Steel rope trailer is the multiduty mechanical device of a kind of high efficiency, the equipment installation, article lifting, parts traction etc. of the departments such as shipbuilding, electric power, post and telecommunications, transport, building, mine can be widely used in, especially in the traction of narrow and small working space, field high altitude operation and various different angles, have more unique preceence.
Existing rope traction device, adopts Non-follow control mostly, and safety and reliability cannot ensure, the weight of traction weight is very limited, and cannot accurately locate.
Summary of the invention
The object of the invention is to the deficiency overcoming existing draw gear, and propose a kind of steel rope straight line draw gear.
The steel rope straight line draw gear that the present invention proposes, by clamping mechanism, guidance set, telescopic oil cylinder assembly and frame base composition, described clamping mechanism, guidance set and telescopic oil cylinder assembly are positioned at frame base, guidance set comprises front guidance set and rear guidance set, clamping mechanism front portion arranges front guidance set, rear portion arranges rear guidance set, steel rope inserts front guidance set successively, clamping mechanism and rear guidance set, clamping mechanism is by wedge, wedge, wedge lining, clamping oil cylinder and spring composition, telescopic oil cylinder assembly is positioned at clamping mechanism both sides, telescopic oil cylinder assembly side connects wedge, wedge is fixed in wedge lining, and wedge is positioned at wedge both sides, and clamping oil cylinder is positioned at wedge lining side, and wedge lining front end is provided with spring near front guidance set side, front guidance set comprises four rollers, is undertaken up and down and left and right guiding by roller, and rear guidance set is combined by the upper end cover of arc transition and bottom end cover, is led, thus prevent the damage of steel rope by upper and lower end cap, during use, one group can be formed by two steel rope straight line draw geares, be used alternatingly, coordinate the flexible of telescopic oil cylinder simultaneously, thus realize straight line traction.
In the present invention, between wedge and wedge, roller is set.
The present invention has following several large advantage:
(1) clamping oil cylinder and spring form a set of active and clamp and initiatively Ding Song mechanism, more reliably clamp and unclamp;
(2) for reducing the friction of all-moving surface between wedge and wedge, roller being installed, cliding friction being changed into friction of rolling;
(3) wedge lining adopts special material, prevents damage of steel cable, increases the friction drag contacted with steel rope simultaneously.
Accompanying drawing explanation
Fig. 1 is the birds-eye view of steel rope straight line draw gear structural representation.
Fig. 2 is the upward view of steel rope straight line draw gear structural representation.
Number in the figure: 1 be front guidance set, 2 be clamping mechanism, 3 be telescopic oil cylinder assembly, 4 be frame base, 5 be rear guidance set, 6 be spring, 7 be wedge, 8 be wedge, 9 be wedge lining, 10 be clamping oil cylinder, 11 for steel rope.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further elaborated.
Embodiment 1: as shown in Figure 1, described device is made up of clamping mechanism 2, front guidance set 1, telescopic oil cylinder assembly 3, frame base 4 and rear guidance set 5, wherein, clamping mechanism 2 is made up of wedge 7, wedge 8, wedge lining 9, clamping oil cylinder 10 and spring 6.Front guidance set 1 carries out up and down and left and right guiding primarily of four rollers, and rear guidance set 5 adopts the end cap up and down of arc transition to lead, thus prevents the damage of steel rope.Utilize two steel rope straight line draw geares, form one group of application force alternately switched, coordinate the flexible of telescopic oil cylinder simultaneously, thus realize straight line traction.
Working process of the present invention is specific as follows:
Utilize two steel rope straight line draw geares, form one group of application force alternately switched, coordinate the flexible of telescopic oil cylinder simultaneously, thus realize straight line traction.Its action can be divided into four steps:
The first, the clamping mechanism 2 of last steel rope straight line draw gear clamps, and the clamping mechanism 2 of a rear steel rope straight line draw gear unclamps, and the telescopic oil cylinder assembly 3 of last steel rope straight line draw gear carries out stretching cylinder, drives and is pulled object traction;
The second, the telescopic oil cylinder assembly 3 of last steel rope straight line draw gear stretches cylinder when arriving a stroke, stops stretching cylinder;
Three, the clamping mechanism 2 of a rear steel rope straight line draw gear clamps, and the clamping mechanism 2 of last steel rope straight line draw gear unclamps, and meanwhile, the telescopic oil cylinder assembly 3 of last steel rope straight line draw gear starts contracting cylinder;
Four, when the telescopic oil cylinder assembly 3 contracting cylinder of last steel rope straight line draw gear arrives bottom, stop contracting cylinder, its clamping mechanism 2 clamps, and starts to enter next circulation.
In the third step, the clamping mechanism of last steel rope straight line draw gear unclamps, in the process of telescopic oil cylinder assembly contracting cylinder, because steel rope is flexible rope, if do not led in rear end, can bend at lower portion, not only last group of clamping mechanism effectively cannot be unclamped, steel rope also can be caused to be subject to breakage.Therefore, the guidance set of steel rope is added in the rear end of draw gear.In the process of straight line traction, front end guiding be upper and lower, left and right two in forward guidance set to guiding wheels, rear end guiding is the guiding that end cap up and down rearward in guidance set carries out steel rope.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
A kind of steel rope straight line draw gear that the present invention provides, has property easy to use, safe and reliability is high, registration, has stronger practicality and higher economy.
