Abstract
The utility model discloses a chain frame is drawn to the endless chain calabash is disclosed, the supporting annexes of two rings chain calabashs, the group will have the ellipse to draw chain piece (1) and web (2) to constitute, solves two rings chain calabashs problem that sprocket and endless chain easily break away from in the operation or when carrying.
Description
Technical field
The invention belongs to electric chain hoist accessory kit.
Background technology
At present, ring-chain hoist mainly solves the ring-chain hoist difficult problem that sprocket wheel and loop chain depart from when operation or carrying with pressing sprocket, and for two suspension ring chain block, market does not also prevent specially the device that sprocket wheel and loop chain depart from.
Summary of the invention
The object of the invention is the two suspension ring chain block of open one and draw chain frame, solve two suspension ring chain block problem that sprocket wheel and loop chain easily depart from when operation or carrying.
Of the present invention pair of suspension ring chain draws chain frame two embodiments---embodiment 1 and embodiment 2, the common ground of two embodiments is, two ellipses draw chain block to be fixed at the two ends of two coupling plates, it is each fluted that two ellipses draw chain block two sides, its cross section is as " work " word shape, the major axis of its ellipse is vertical with the long limit of coupling plate, two coupling plates clip two ellipses and draw chain block, chain draws through engaging with head sprocket between chain block from two ellipses, and the outside that chain draws chain block from two ellipses is passed and side sprocket engagement.
In embodiment 1, of the present invention pair of suspension ring chain draws chain shelf structure and also comprises bearing pin, one end that two ellipses draw chain block is respectively provided with bearing pin, two bearing pins pass two coupling plates and draw chain block, two bearing pins are vertical with the face of coupling plate, and draw chain block interference fit with two coupling plates and ellipse, the two ends of two bearing pins coordinate with the slide on the wallboard of two suspension ring chain block respectively, two suspension ring chain draw chain frame can with chain swinging horizontal sliding.
In embodiment 2, of the present invention pair of suspension ring chain draws chain shelf structure and also comprises small boss, two coupling plates respectively there are two small boss, the central junction line being positioned at the relative small boss of two of drawing chain block two ends is vertical with the face of two coupling plates, the cross section of its small boss is circular, also can be oval, rectangle.
It is simple that the of the present invention pair of suspension ring chain draws chain shelf structure, can direct casting, and reliable operation, solves novel two suspension ring chain blocks problem that sprocket wheel and loop chain easily depart from when the torsion of operation chain, sprocket wheel are stung chain and carry.
Detailed description of the invention
Technical characteristic of the present invention is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of two suspension ring chain draws chain frame, there are two kinds of embodiments---embodiment 1 and embodiment 2, the common ground of two embodiments is: this ring-chain hoist draws chain frame and all comprises and draw chain block (1) and coupling plate (2), it is oval for drawing chain block (1), and it is each fluted to draw chain block (1) two sides, and its cross section is as " work " word shape, two ends between two coupling plates (2) are each to be fixed one and draws chain block (1), and namely two coupling plates (2) clip two ellipses and draw chain block (1).As shown in Figure 9, two ellipses major axis of drawing chain block (1) is vertical with the long axis of coupling plate (2).
As shown in Fig. 2, Fig. 5, Fig. 8, this ring-chain hoist draws chain frame and is arranged on ring-chain hoist, the chain (8) of chain (8) and head sprocket (7) engagement place draws between chain block (1) from two and passes through, pass through from the outside of drawing chain block (1) with the chain (8) of auxiliary sprocket wheel (6) engagement place, ellipse draws chain block (1) and the distance between head sprocket (7) and auxiliary sprocket wheel (6) and is less than the maximum outer wide of chain (7) and to be greater than chain maximum outer wide by 1/2nd, and can not reverse when chain (8) is worked and sting chain and chain not easily departs from sprocket wheel when carrying.
As shown in Figure 3, Figure 4, in embodiment 1, this ring-chain hoist draws chain frame and also has bearing pin (4), it is oval for drawing chain block (1), and bearing pin (4), through drawing chain block (1) and coupling plate (2), draws chain block (1) porose, vertical two coupling plates (2) of bearing pin (4), with two coupling plate (2) interference fit, chute (9) bearing fit of the two ends of two bearing pins (4) and the wallboard (4) of two suspension ring chain block, two suspension ring chain draw chain frame can with chain swinging horizontal sliding.
As Fig. 5, shown in Fig. 6, in embodiment 2, this ring-chain hoist draws chain frame and also includes small boss (5), two coupling plates (2) respectively there are two small boss (5), namely four small boss (5) protrude in the outside at two coupling plate (2) two ends respectively, the central junction line being positioned at the relative small boss (5) of two of drawing chain block (1) two ends is vertical with the face of two coupling plates (2), the section of its small boss (5) is circular, also can be oval or rectangle, four protrude axle head (5) and coordinate with the slide of the wallboard (4) of two suspension ring chain block, two suspension ring chain draws chain frame and can move about by horizontal sliding with chain swinging, this kind of embodiment is when foundry technique is selected in production, draw four small boss (5) of chain frame, draw chain block (1) and coupling plate (2) and be cast as one as preferably.
