Description
Technical field
The present invention relates to piston compressors to assemble parts technical field, built in especially a kind of piston compressor use
Elastic locking block is stably connected with device.
Background technique
It is often excessively connected using crosshead in the connection of connecting rod and piston rod in reciprocating compressor, piston rod
It is connect with connecting rod so that piston rod not will receive connecting rod bring lateral pressure by crosshead.The friction of piston and cylinder in this way is
It is the smallest.And crosshead and piston rod can only axially move, and can make full use of the volume of cylinder, control the side of lubricating oil
Method is fairly simple, increases the service efficiency of compressor.
Although there are many mode connected between piston rod and crosshead in reciprocating compressor, most of connection types
In be not that quality is bigger, exactly install it is more complicated, and in middle-size and small-size compressor crosshead quality size to pressure
The trim of contracting machine has a great impact.So installation is simple, the connection type of light weight at middle-size and small-size compressor first choice, and
Threaded connection just meets above-mentioned requirement.So the use of be most commonly used being exactly to be threadedly coupled in middle-size and small-size compressor.
Usually by piston rod, cross nut, one double nut lock of crosshead block composition in traditional threaded connection
Clamping system, and install a locked spacer additional between cross nut and crosshead block, by cross nut and crosshead
A possibility that mutually moving between ontology is preferably minimized, so that double nut fastening system is preferably locked, but double nut is locked
In it is higher to the torque requirement of nut check, locking torque is big, screw thread can be destroyed, stripped thread is caused to loosen, locking torque it is small can twist
Not tight nut will also result in loosening, and when breaking curved locked spacer and being tightly attached on cross nut by it, need using hammer
Son beats, and the tooth silk on nut is probably destroyed during beaing, to influence tightening for nut.
The working time of compressor is generally all special long, and reciprocal inertia force is also bigger, and double nut fastening system is in length
Will necessarily be loosened under the action of time reciprocal inertia force, a piece of locked spacer may prevent in a short time cross nut and
The mutual movement of crosshead block, but for a long time, under high-intensitive work, locked spacer itself can may be deformed also and lose work
With.Once generating to loosen between piston rod and crosshead and often generating great security risk, cylinder is hit, what generation can not balance
Torque accelerates the abrasion of piston and cylinder, the serious tragedy that may generate fatal crass.
Summary of the invention
The technical problem to be solved by the present invention is providing one kind in order to solve the problems, such as above-mentioned background technique and changing
Into piston compressor built-in elastic latch segment be stably connected with device, solve the problems, such as above-mentioned background technique.
The technical solution adopted by the present invention to solve the technical problems is: a kind of piston compressor is locked with built-in elastic
Block is stably connected with device, including crosshead block, is fixed on the crosshead nut of crosshead block upper end and is fixed on cross
Piston rod on head nut, the crosshead block upper surface is located at crosshead nut periphery and offers a plurality of ring quasi arrays
The fixed blind hole of the internal screw thread of arrangement, the crosshead block upper surface correspond to the fixed blind hole position of internal screw thread and are provided with steel square
Plate, the right angle lower surface of steel plate offers a plurality of underlying connection through-holes matched with the fixed blind hole of internal screw thread, described
The fixing bolt that passes through inside underlying connection through-hole of right angle steel plate screw in inside the fixed blind hole of internal screw thread and on crosshead block
Surface is fixedly connected, and is offered on the right angle steel plate right side wall and is set connection through-hole on a plurality of, the crosshead nut
Outside is provided with fastening bloom, and the fastening bloom lower end offers the fitting groove matched with right angle steel plate, and described is tight
It is connected and fixed on right angle steel plate with right angle steel plate upper end Gu bloom is covered by lower end fitting groove, the nearly cross of fastening bloom
Round telescopic chute is offered on head nut side wall, is provided with latch between the crosshead nut and fastening bloom, it is described
Latch nearly crosshead nut face on offer lock groove, by inside telescopic chute between the latch and fastening bloom
Extruding spring be connected.
Further, the telescopic chute inner sidewall center offers logical through the internal screw thread connection for fastening bloom
Hole, the fastening bloom are passed through by the fixing bolt inside internal screw thread connection through-hole and above set connection through-hole inside and steel square
Plate is fixedly connected.
Further, the latch and extruding spring connection side wall center offer and connect through-hole with internal screw thread
The internal screw thread adjustment hole matched.
Further, the latch connects the fixing bolt inside through-hole by internal screw thread and screws in internal screw thread adjustment hole
Portion adjusts the distance between fastening bloom.
The invention has the advantages that a kind of piston compressor built-in elastic latch segment of the invention is stably connected with
Device is slotting on right angle steel plate by fixed with the right angle steel plate for setting connection through-hole above and below in crosshead block upper end bolt
The fastening bloom for connecing built-in elastic latch, using the fixing bolt inside fastening bloom screw in internal screw thread adjustment hole fixing and
The case where position for adjusting latch, avoids middle-size and small-size compressor excessive in reciprocal inertia force, longevity of service, great work intensity
Lower piston rod is easy the problem of loosening, and effectively improves the safety and reliability that compressor continues working.
