Abstract
The invention discloses a chain, which comprises a plurality of continuous chain units, wherein each chain unit comprises an external chain plate and an internal chain plate and a sleeve which are in clearance fit; wherein a pin shaft is sleeved in the sleeve; the two ends of the pin shaft extend out of the sleeve; the external chain plate is connected with the two extended ends of the pin shaft; and the internal chain plate has two layers of parallel chain separating plates. The chain has the advantages of high strength, high bearing capacity, long service life and reliable operation. The service life of the chain is 4 to 5 times that of common chains.
Description
Technical field:
The present invention relates generally to electronic loop chain lift field, relates in particular to a kind of chain that is used for electronic loop chain lift.
Background technique:
Electronic loop chain lift is a kind of little heavy-duty hoisting equipment, is widely used in industrial and mining enterprise, warehouse, commerce, medical and health and catering service.It can be installed in unsettled I-shape beam, and curvilinear gudie way and fixing handling weight also can be installed on the guide rail that cantilever hangs, and are weights such as lathe lifting workpiece and anchor clamps.In the prior art, the employed chain of electronic loop chain lift is easy to wear, and working life is short, therefore needs often chain to be changed, and so, maintenance expenses is higher and wasted the time.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of prior art, to provide a kind of simple in structure, nonabradable chain.
The present invention is achieved by the following technical solutions:
A kind of chain, it is characterized in that: include a plurality of continuous chain units, each chain unit includes the inner plate and the sleeve of outer plate and interference fit, is set with bearing pin in the sleeve, all stretch out outside the sleeve at the bearing pin two ends, and described outer plate is connected the external part of two bearing pins; Described inner plate includes two-layer branch carrier bar arranged side by side.
Advantage of the present invention is as follows:
Inside and outside carrier bar among the present invention selects for use superior alloy steel through the special processing of hardening, and therefore, has the intensity height, bearing capacity is big, the life-span is long, the advantage of reliable operation.Be 4-5 times of common chain its working life.
Description of drawings:
Fig. 1 is a plan view of the present invention.
Fig. 2 is a plan view of the present invention.
Embodiment:
Referring to accompanying drawing.
A kind of chain, include a plurality of continuous chain units 5, each chain unit 5 includes the inner plate 2 and the sleeve 3 of outer plate 1 and interference fit, is set with bearing pin 4 in the sleeve 3, all stretch out outside the sleeve 3 at bearing pin 4 two ends, and described outer plate 1 is connected the external part of two bearing pins 4; Described inner plate 2 includes two-layer branch carrier bar 6 arranged side by side.
