The specific embodiment
In order to make those skilled in the art person understand technical scheme in the utility model better, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
The utility model embodiment provides a kind of tackling system that is used on the tower bar, with the simple lifting of the body of realizing the tower bar.
Fig. 1 shows a kind of annexation of above-mentioned tower bar and above-mentioned tackling system, and the tower bar comprises body 1 and the pedestal 2 that is rotatably connected, and tackling system then comprises capstan winch assembly and the fixed pulley assembly 8 that is arranged on the pedestal 2, and is arranged at the lever assembly on the body 1;
The lever assembly comprises lever 3 and support 4, and support 4 is fixed in the bottom of described body 1, and described lever 3 one ends are hinged by rotating shaft 5 and support 4, and the other end runs through body 1;
The capstan winch assembly comprises twisted wire 6 and the capstan winch 7 that is fixed on the pedestal 2, and twisted wire 6 one ends are connected with capstan winch 7, and the other end is walked around the fixed pulley assembly and is connected with lever 3.In addition, in other embodiment of the utility model, twisted wire 6 can also be connected with support 4.In the specific implementation, capstan winch 7 can be electric capstan, hydraulic windlass etc., and to save manpower, as long as guarantee in the lifting process, capstan winch can tighten up twisted wire, provides the needed pulling force of lifting to get final product.
As seen, in the above-described embodiments, be provided with the tackling system that lever assembly, fixed pulley assembly 8 and capstan winch assembly etc. are formed on the tower bar, the capstan winch assembly is connected with the support 4 or the lever 3 of lever assembly by twisted wire 6.When lifting, capstan winch 7 that can be by rotating the capstan winch assembly provides pulling force to tighten up twisted wire 6 to support 4 or with lever 3 that support 4 is hinged, and an end of lever 3 runs through the body 1 of tower bar, and lever 3 drives the rotation that body 1 is done with respect to pedestal 2 like this, also is that body 1 is sling.Because lever assembly, fixed pulley assembly and the capstan winch assembly of tower bar itself can be realized the lifting of body 1, therefore do not need additionally to settle again tripod, also, realized the simple lifting of the body 1 of tower bar with regard to having exempted a series of problems because of using tripod to bring.
For reducing the suffered friction of twisted wire in the lifting process 6, referring to Fig. 2, in other embodiment of the utility model, the lever assembly also can comprise pulley 9, pulley 9 is connected with lever 3 with support 4 (also being pulley 9, support 4 and lever 3 shared rotating shafts 5) by rotating shaft 5, and twisted wire 6 is walked around pulley 9 and is connected with support 4 or lever 3.
In another embodiment of the utility model, referring to Fig. 3 a and Fig. 3 b, support also can comprise two legs 301 of the bottom of being fixed in body 1 and be arranged at the cross bar 302 of 301 of two legs, like this, lever 3 and two legs 301 constitute trishores, and when lifting, the suffered power of lever assembly is dispersed on lever 3 and two legs 301, thereby strengthened the steadiness of lever assembly, the position that prevents lever assembly in the lifting process changes or skids off.And twisted wire 6 walks around pulley 9 and can be connected with cross bar 302, also made things convenient for being connected of twisted wire 6 and support.
In other embodiments, referring to Fig. 4, the lever 3 in the foregoing description is exposed on body 1 position outward can be provided with the limiting component 401 that restriction body 1 slides.Limiting component 401 quantity can be one or more, when being one, limiting component 401 can be arranged on the unsettled end of lever 3, prevent that body 1 from gliding break away from the purpose of lever 3 in the lifting process to reach.And when being a plurality of, can be divided into the two ends of lever 3 in the quantity of limiting component 401, slidably reciprocate along lever 3 to prevent body 1.When specific implementation, limiting component 401 can be clamp or other existing parts, does not do qualification in the utility model.Certainly, if lever 3 long enough, so that in the lifting process, would not do not need to limit limiting component even body 1 downslide also can't break away from 3 on lever.
Need to prove that lever assembly, fixed pulley assembly and the concrete position of capstan winch assembly are not limited in the utility model, for example, fixed pulley always and with the capstan winch assembly can be arranged on the homonymy of pedestal or be divided into the pedestal both sides.As long as guaranteeing that the three cooperatively interacts can drive body and rotate with respect to pedestal, body 1 is sling to get final product.
In the process of lifting body 1, referring to Fig. 5, body 1 is connected in first fulcrum 501 (first fulcrum 501 is positioned on the body 1) with pedestal 2, and twisted wire 6 contacts with the fixed pulley assembly in second fulcrum 502 (second fulcrum 502 is positioned on the fixed pulley assembly).As desire to make body 1 to rotate with respect to pedestal 2, then need body 1 to be applied application force by the lever assembly.According to lever principle, when being not less than 1 lifting of (also promptly more than or equal to) body, the moment that provides when twisted wire 6 during needed moment, body 1 is rotated with respect to pedestal 2.Also promptly, the center of gravity of the pulling force N that twisted wire 6 provides, the gravity G of body 1, body 1 and the horizontal throw L between first fulcrum 501, and the vertical distance H between the rotating shaft 5 and second fulcrum 502 need satisfy formula: GL≤NH.
When above-mentioned tower lever system is designed to: when the line of centers 503 of body 1 is not less than 90 ° with the line of centers 504 of pedestal 2 along the angle that lifts by crane direction, the twisted wire of tightening 6 is 45 ° with the angle of lever 3, also promptly in the lifting process, after line of centers 504 angles of the line of centers 503 of body 1 and pedestal 2 are more than or equal to 90 °, when the direction of pulling force N and the angle of lever were always 45 °, the required size of pulling force N that applies was for minimum.
More than lever assembly among all embodiment be removable installed on the body, and capstan winch assembly and fixed pulley assembly also are removable installed on the pedestal.Also be that tackling system can be separated with the tower bar.Like this, when a plurality of tower bar is installed, only need to finish the installation of the body of a plurality of tower bars once the cover tackling system.
Corresponding with it, the utility model embodiment also provides a kind of tower lever system simultaneously, and this tower lever system comprises the tackling system among tower bar and above-mentioned all embodiment, and this tackling system is installed on the tower bar.
The above only is the specific embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
