Description
Technical field
The utility model 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, can be widely used in equipment installation, article lifting, parts traction of the departments such as shipbuilding, electric power, post and telecommunications, transportation, building, mine etc., 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, mostly adopts manually and controls, and safety and reliability cannot guarantee, the weight of traction weight is very limited, and cannot accurately locate.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing draw gear, and has proposed a kind of steel rope straight line draw gear.
The steel rope straight line draw gear the utility model 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 one 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 one side, and wedge lining front end is provided with spring near front guidance set one side, front guidance set comprises four rollers, by roller, carries out upper and lower and left and right guiding, and rear guidance set is combined by upper end cover and the bottom end cover of arc transition, leads, thereby prevent the damage of steel rope by upper and lower end cap, during use, can form one group by two steel rope straight line draw geares, be used alternatingly, coordinate the flexible of telescopic oil cylinder simultaneously, thereby realize straight line traction.
In the utility model, between wedge and wedge, roller is set.
The utlity model has following several large advantages:
(1) clamping oil cylinder and spring form a set of active clamping and active Ding Song mechanism, clamp more reliably and unclamp;
(2) for reducing the friction of all-moving surface between wedge and wedge, roller is installed, changes cliding friction into friction of rolling;
(3) wedge lining adopts special material, prevents damage of steel cable, increases the friction drag contacting 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 is that front guidance set, 2 is that clamping mechanism, 3 is that telescopic oil cylinder assembly, 4 is that frame base, 5 is that rear guidance set, 6 is that spring, 7 is that wedge, 8 is that wedge, 9 is that wedge lining, 10 is that clamping oil cylinder, 11 is steel rope.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further elaborated.
Embodiment 1: as shown in Figure 1, described device is comprised 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 comprised of wedge 7, wedge 8, wedge lining 9, clamping oil cylinder 10 and spring 6.Front guidance set 1 mainly by four rollers, is undertaken up and down and lead in left and right, and rear guidance set 5 adopts the end cap up and down of arc transition to lead, thereby prevents the damage of steel rope.Utilize two steel rope straight line draw geares, form one group of application force alternately switching, coordinate the flexible of telescopic oil cylinder simultaneously, thereby realize straight line traction.
Working process of the present utility model is specific as follows:
Utilize two steel rope straight line draw geares, form one group of application force alternately switching, coordinate the flexible of telescopic oil cylinder simultaneously, thereby 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 is stretched cylinder, drives and is pulled object traction;
When the second, the telescopic oil cylinder assembly 3 of last steel rope straight line draw gear is stretched a stroke of cylinder arrival, stop 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 cylinders of last steel rope straight line draw gear arrive bottom, stop contracting cylinder, its clamping mechanism 2 clamps, and starts to enter next circulation.
In the 3rd 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 in framework inside, not only last group of clamping mechanism effectively cannot be unclamped, also can cause steel rope to be subject to breakage.Therefore, in the rear end of draw gear, increased the guidance set of steel rope.In the process of straight line traction, front end guiding is upper and lower, two pairs of the left and right guiding wheels in forward guidance set, and rear end guiding is the guiding of carrying out steel rope by the end cap up and down in rear guidance set.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
A kind of steel rope straight line draw gear that the utility model provides, has property easy to use, safe and reliability is high, registration, has stronger practicality and higher economy.
