Abstract
The utility model relates to construction of a lifting mechanism cargo platform, in particular to an anti-looseness locking device for lifting circular chains. The anti-looseness locking device for the lifting circular chains solves the technical problems and prevents the lifting circular chain of a lifting mechanism from loosening. The anti-looseness locking device for the lifting circular chains includes that transmission of a circular chain D1 is connected to a locking device A1 through a circular chain wheel B1, a connector C1 of the locking device A1 is connected with a lifting chain E1 and a circular chain D2, transmission is carried out through a duplex chain wheel B, and the lifting of the lifting chain E1 is driven through a transmission chain wheel B2; the circulating chain D2 is connected with a locking device A2, a connecting screw and a connector C2 are arranged in the locking device A2, the connecting screw is connected with the starting end of the circulating chain D1, and circular connection is formed; the connector C2 is connected with the circular chain D2 and a lifting chain E2, and the lifting of the lifting chain E2 is driven through a transmission chain wheel B3. The anti-looseness locking device for the lifting circular chains can effectively prevent looseness of the lifting circular chains, and accordingly the lifting mechanism platform keeps stable after objects are carried on the platform, and the functions of no looseness and no dropping are achieved.
Description
Technical field
The present invention relates to the construction of lifting mechanism article carrying platform, particularly the anti-loosening blocking device of a kind of lifting endless chain.
Background technology
At present, behind the lifting mechanism carrying object, because the effect of object gravity, easily be directed at the loosening of its lifting circulation link chain, thereby be directed at the instability of lifting mechanism platform, loosening whereabouts phenomenon easily takes place, loosening for the lifting circulation link chain that prevents lifting mechanism, the anti-loosening blocking device of special a kind of lifting endless chain of research and development.
Summary of the invention
The problem to be solved in the present invention is the technical matters that prevents that lifting mechanism lifting circulation link chain is loosening.
In order to address the above problem, the technological means that the present invention adopts is:
Its structure comprises: circulation link chain D1(2) transmission is by circulation sprocket wheel B1(1) be connected to blocking device A1(3), the connector C1(3-1 of blocking device A1) with elevating chain E1(3-2), circulation link chain D2(3-3) be connected, transmission is by duplex chain wheel B(4), elevating chain E1 is through driving chain wheel B2(5) drive the lifting of elevating chain E1; Circulation link chain D2 and blocking device A2(6) be connected, in blocking device A2, be provided with connecting screw rod (6-1), connector C2(6-2), connecting screw rod is that the top of circulation link chain D1 connects, and constitutes a circulation and links to each other; Connector C2 and circulation link chain D2, elevating chain E2(7) be connected, elevating chain E2 is through driving chain wheel B3(8) drive the lifting of elevating chain E2.
The present invention can effectively prevent the loosening of lifting circulation link chain, and circulation link chain is realized synchronization lifting through elevating chain E1, elevating chain E2, thereby makes held stationary behind the lifting mechanism platform bearer object, and the effect of loosening whereabouts does not take place.
Description of drawings
Concrete structure of the present invention is provided by the following drawings.
Fig. 1, Fig. 2, Fig. 3 are the organigrams of the anti-loosening blocking device of lifting endless chain of proposition according to the present invention.
Sign among accompanying drawing 1 Fig. 2 Fig. 3 is represented respectively:
1, circulation sprocket wheel B1 2, circulation link chain D1 3, blocking device A1 3-1, connector C1 3-2, elevating chain E1 3-3, circulation link chain D2 4, duplex chain wheel B 5, driving chain wheel B2 6, blocking device A2 6-1, connecting screw rod 6-2, connector C2 7, elevating chain E2 8, driving chain wheel B3
The specific embodiment
Principle of work of the present invention: power is through circulation link chain D1(2) transmission is by circulation sprocket wheel B1(1) be connected to blocking device A1(3), the connector C1 of blocking device A1 is connected with circulation link chain D2, transmission is by duplex chain wheel B(4), circulation link chain D2 and blocking device A2(6) be connected, being provided with connecting screw rod in blocking device A2 is circulation link chain D1(2) top connect, thereby constitute a circulation and be connected, make its back and forth movement in certain stroke range, the balance that keeps chain carrying dynamics, not loosening, and elevating chain E1 is through driving chain wheel B2(5) drive the lifting of elevating chain E1, elevating chain E2(7) through driving chain wheel B3(8) drive the lifting of elevating chain E2, realize synchronization lifting like this, thereby make held stationary behind the lifting mechanism platform bearer object, loosening effect of falling does not take place.
The present invention is applicable to installing and using of lifting mechanism platform construction, lifting parking stall, and it can effectively prevent the loosening of lifting circulation link chain, thereby makes held stationary behind the lifting mechanism platform bearer object, and the loosening phenomenon that falls does not take place.
