Abstract
The utility model discloses a hydrogen nitrogen compressor cross head pin convenient to dismantle, including the cross head pin, its characterized in that: the one end of cross head pin is the cylinder, the one end of cross head pin has the screw hole, high -pressure bolt is installed in the threaded hole cooperation. The utility model discloses the result of use is good, has improved hydrogen nitrogen compressor cross head pin utilization ratio, and it is convenient to dismantle, labour saving and time saving.
Description
Technical field
The utility model relates to a kind of mechanical frock, specifically a kind of easy-to-dismount hydrogen nitrogen cross head pin of compressor.
Background technique
In use, moving element is fragile for hydrogen nitrogen compressor, and particularly connecting rod small-end bearing, crosshead and pin are fragile, and pin of must dismantling during replacing, could change connecting rod small-end bearing, crosshead and pin.For ensureing compressor safe operation, connecting rod pin is taper, and it is interference fit that pin coordinates with crosshead, must pound tight when pin is installed.Operationally crosshead, pin are heated, stressed etc. affect crosshead and pin all finds the changes such as expansion, distortion, therefore pin of dismantling when changing connecting rod small-end bearing, crosshead and pin is very difficult at every turn, dismantle a pin 4-5 hour, the even longer time, even if pin has been pounded, can but scrap by pin.
Model utility content
It is good that the utility model object there is provided a kind of using effect, improves the sub-utilization ratio of hydrogen nitrogen cross head pin of compressor, convenient disassembly, time saving and energy saving drive easy-to-dismount hydrogen nitrogen cross head pin of compressor.
The utility model technical solution problem provides following scheme:
Easy-to-dismount hydrogen nitrogen cross head pin of compressor, comprises crosshead pin, it is characterized in that: one end of described crosshead pin is cylindrical body, and one end of described crosshead pin has tapped hole, coordinates and be provided with high-pressure bolt in described tapped hole.
The upper end high pressure nut of described high-pressure bolt is fastening.
The utility model the tightening force by circular orifice high-pressure bolt easily dismantle hydrogen nitrogen cross head pin of compressor, meet safety standard completely, using effect is good, improve the sub-utilization ratio of hydrogen nitrogen cross head pin of compressor, convenient disassembly, time saving and energy saving, there is very high use value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See accompanying drawing, a kind of easy-to-dismount hydrogen nitrogen cross head pin of compressor, comprise crosshead pin 1, one end of described crosshead pin 1 is cylindrical body 2, and one end of described crosshead pin 1 has tapped hole 3, coordinates and be provided with high-pressure bolt 4 in described tapped hole 3.
The upper end high pressure nut fastening 5 of described high-pressure bolt 4.
Claims (2)
