Abstract
The invention discloses a conveyor chain of a hoisting machine. The conveyor chain comprises an outer chain plate and an inner chain plate, a pin shaft is used for combining the outer chain plate, the inner chain plate and rollers, and the side surface part of a long hole of the outer chain plate is thickened by a die pressing or material adding method, so that the matching area between the long hole of the outer chain plate and the pin shaft is increased and the service life of the conveyor chain can be prolonged.
Description
Technical field
The present invention relates to a kind of chain, particularly a kind of chain of gig.
Background technology
According to production and operation marketing unit reflection, thereby and the pin link plate that damages on their a kind of plate link chain type hoist of sending recognize because the chain stripe pitch is large, torsion is large, and pin link plate is thin, and the pin link plate hole cooperates contact surface little with bearing pin, torsion is inadequate, and elongated hole is twisted into circular hole, serious wear, be easy to the bearing pin that fractures, use some months just to need to change chain, chain of every replacing needs about 20,000 yuan, cause larger waste, also increased the labour intensity that the workman changes chain.
Summary of the invention
The purpose of this invention is to provide a kind of conveying chain for hoister.
The solution of the present invention is: a kind of conveying chain for hoister, comprise pin link plate and inner plate, with bearing pin pin link plate and inner plate and roller are combined, the sideway stance of pin link plate elongated hole is thickened the 3-6 millimeter with mold pressing or the method for adding material, make not yielding becoming flexible of bearing pin and cooperating of pin link plate elongated hole.
Advantage of the present invention is: strengthen the pin link plate elongated hole and make bearing pin and cooperating of pin link plate elongated hole not yielding loosening with the area that cooperates of bearing pin, can prolong the used life of chain, firmly save.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is conveying chain for hoister structural representation of the present invention.
Fig. 2 is pin link plate planar view of the present invention.
Among the figure: 1. pin link plate 2. inner plates 3. rollers 4. bearing pins 5. sideway stances 6. elongated holes.
The specific embodiment
Such as Fig. 1, a kind of plate link chain type hoist chain shown in Figure 2, comprise pin link plate 1 and inner plate 2, with bearing pin 4 pin link plate 1 and inner plate 2 and roller 3 are combined, the sideway stance 5 usefulness mold pressings of the elongated hole 6 of pin link plate 1 or the mode of adding material are thickened the 3-6 millimeter, recruitment is equivalent to about 1/3rd of pin link plate 1 thickness, the size that matches of the elongated hole 6 of corresponding increase bearing pin 4 and pin link plate 1, the elongated hole 6 that strengthens pin link plate 1 can improve the torsion about 30% of cooperation place with the area that cooperates of bearing pin 4, make bearing pin 4 and pin link plate 1 elongated hole 6 cooperate not yielding looseningly, can prolong service life of chain.
Claims (1)
1. conveying chain for hoister, comprise pin link plate (1) and inner plate (2), with bearing pin (4) pin link plate (1) and inner plate (2) and roller (3) are combined, it is characterized in that: the sideway stance (5) of the elongated hole (6) of pin link plate (1) is thickened the 3-6 millimeter with mold pressing or the mode of adding material, make bearing pin (4) and pin link plate (1) elongated hole (6) cooperate not yielding becoming flexible.
