Abstract
The utility model discloses a kind of hold down gag for piston compressor crosshead pin, comprise crosshead pin, crosshead body, described crosshead pin is arranged in crosshead body by bolt, it is characterized in that: described crosshead pin big end surface is provided with circular plate outward, described circular plate is provided with multiple equally distributed tapped through holes, in the tapped through hole of described circular plate, is all furnished with screw, described crosshead body is provided with multiple equally distributed tapped holes, and described circular plate is screwed and is connected on crosshead body.Hold down gag for piston compressor crosshead pin described in the utility model, utilizes screw that circular plate is bolted on crosshead body, effectively stops crosshead pin to exit; Simultaneously, in the time of certain loosened screw, circular plate disequilibrium can be sent the sound, and other screw can also tie down circular plate and seals crosshead pin a period of time, is beneficial to timely discovery and shuts down maintenance, avoids crosshead pin to deviate from and causes equipment damage accident.
Description
Technical field
The utility model relates to a kind of hold down gag for piston compressor crosshead pin.
Background technique
The work of piston compressor is that cylinder, air valve and reciprocating piston forms in cylinder swept volume have constantly changed.Piston compressor is mainly made up of parts such as body, bent axle, connecting rod, piston group, valve, shaft seal, oil pump, energy conditioner, oil circulating systems.Crosshead in bent axle is the part that connects piston and connecting rod, has leading role.At present, crosshead pin is only tight by being positioned at the turnbuckle bolt at Xiao center, once loosening, when stopper ring lost efficacy again, can deviate from short notice, cause great equipment damage accident.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of hold down gag for piston compressor crosshead pin.
To achieve these goals, the technical solution adopted in the utility model is:
Hold down gag for piston compressor crosshead pin described in the utility model, comprise crosshead pin, crosshead body, described crosshead pin is arranged in crosshead body by bolt, it is characterized in that: described crosshead pin big end surface is provided with circular plate outward, described circular plate is provided with multiple equally distributed tapped through holes, in the tapped through hole of described circular plate, is all furnished with screw, described crosshead body is provided with multiple equally distributed tapped holes, and described circular plate is screwed and is connected on crosshead body.
Further, the quantity of the tapped hole on the tapped through hole on described circular plate, screw, crosshead body is 4.
Compared with prior art, the beneficial effects of the utility model:
Hold down gag for piston compressor crosshead pin described in the utility model, utilizes screw that circular plate is bolted on crosshead body, effectively stops crosshead pin to exit; Simultaneously, in the time of certain loosened screw, circular plate disequilibrium can be sent the sound, and other screw can also tie down circular plate and seals crosshead pin a period of time, is beneficial to timely discovery and shuts down maintenance, avoids crosshead pin to deviate from and causes equipment damage accident.
Brief description of the drawings
Fig. 1 is the sectional structure schematic diagram of the hold down gag for piston compressor crosshead pin described in the utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, hold down gag for piston compressor crosshead pin described in the utility model, comprise crosshead pin 2, crosshead body 1, described crosshead pin 2 is arranged in crosshead body 1 by bolt, it is characterized in that: described crosshead pin 2 big end surface are provided with circular plate 3 outward, described circular plate 3 is provided with four equally distributed tapped through holes, in the tapped through hole of described circular plate 3, is all furnished with screw 4, described crosshead body 1 is provided with four equally distributed tapped holes, and described circular plate 3 is fixedly connected on crosshead body 1 by screw 4.
Hold down gag for piston compressor crosshead pin described in the utility model, utilizes screw 4 that circular plate 3 is bolted on crosshead body 1, effectively stops crosshead pin 2 to exit; Simultaneously, in the time that certain screw 4 is loosening, circular plate 3 disequilibriums can be sent the sound, and other screw 4 can also tie down circular plate 3 and seals 2 a period of times of crosshead pin, is beneficial to timely discovery and shuts down maintenance, avoid crosshead pin 2 to deviate from and cause equipment damage accident.
