Description
Technical field
The utility model is related to middle-size and small-size compressor fields, and in particular to one kind allows compressor crosshead to be connect with piston rod
Stable device.
Background technology
It is often excessively connected using crosshead in the connection of connecting rod and piston rod in reciprocating compressor, piston rod
It is connect so that the lateral pressure that piston rod will not be brought by connecting rod with connecting rod by crosshead.The friction of piston and cylinder in this way is
Minimum.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 the side connected between piston rod and crosshead in reciprocating compressor
There are many formula, but are not that quality is bigger in most of connection types, exactly install more complicated, and middle-size and small-size compression
The quality size of crosshead has a great impact to the trim of compressor in machine.So installation is simple, the connection type of light weight
At the first choice of middle-size and small-size compressor, and it is threadedly coupled and just meets above-mentioned requirement.So being used in middle-size and small-size compressor
Be most commonly used it is exactly to be threadedly coupled.
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
The possibility mutually moved between ontology is preferably minimized, and to preferably lock double nut fastening system, but double nut is locked
In it is higher to the torque requirement of nut check, locking torque is big, can destroy screw thread and 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, locked to influence tightening for nut.Compressor
Working time is generally all special long, and reciprocal inertia force is also bigger, and double nut fastening system is in long-time reciprocal inertia force
It will necessarily be loosened under effect, a piece of locked spacer may prevent the mutual of cross nut and crosshead block in a short time
Movement, but for a long time, under the work of high intensity, locked spacer itself can may also deform ineffective.
Utility model content
The technical problem to be solved by the utility model is to provide one kind, and compressor crosshead to be allowed to be connect surely with piston rod
Fixed device can solve the problems, such as that piston rod can not be locked mutually with crosshead in middle-size and small-size compressor.
Technical problem to be solved in the utility model is realized using technical solution below：
A kind of device for allowing compressor crosshead and piston rod stable connection, including fastening steel plate, right angle steel plate and cross
Head ontology drills through the internal thread hole of installation right angle steel plate in the Right vertical of the crosshead block top crosshead pin hole,
The position of corresponding crosshead block top internal thread hole drills through the identical hole of size in right angle steel plate vertical plate, in right angle steel plate
Apertured on transverse plate, the position in hole drills on corresponding right angle steel plate transverse plate on fastening steel plate.On the fastening steel plate
Hole on hole and right angle steel plate vertical plate and transverse plate is through-hole.
Hole in the right angle steel plate vertical plate is identical as the size of crosshead block top internal thread hole, and right angle steel plate is horizontal
Hole on plate is identical as the pore size on fastening steel plate.The fastening steel plate and right angle steel plate transverse plate using studs and
Nut connects, and right angle steel plate vertical plate is connected by screw bolts with crosshead block crosshead pin hole.The fastening steel plate and right angle
Steel plate does acute angle and falls blunt processing.
Preferably, for better stability, on right angle steel plate transverse plate and fastening steel plate corresponding position set two it is logical
Hole, and connected respectively with studs.
Preferably, in order to facilitate the installation of, it and prevents from mutually colliding influence work, right angle steel plate vertical plate with studs
On through-hole can be set as counterbore, bolt can select dormant bolt.
The operation principle of the utility model：Right angle steel plate is bolted on crosshead block, and fastening steel plate is stuck
Then cross nut is fixed on by studs on right angle steel plate, so right angle steel plate and fastening steel plate and fastener are simultaneously
Without and piston rod generate and be directly connected to, therefore the reciprocal inertia force suffered by right angle steel plate and fastening steel plate and fastener compares
It is small, it will not be loosened after fixed.
The utility model has the beneficial effects that：Right angle steel plate and fastening steel plate and fastener are not generated with piston rod
It is directly connected to, therefore the reciprocal inertia force suffered by right angle steel plate and fastening steel plate and fastener is smaller, it will not after fixed
It loosens, fastening effect is good so as to effectively prevent the mutual movement between cross nut and crosshead block, further
Crosshead and piston rod have been locked, reliability and safety are improved.Further more, being risen to cross nut and crosshead block tooth silk
Protective effect has been arrived, it may be to that can be caused to cross nut and crosshead block tooth silk because being not present during the installation process
The operation of destruction can be effectively protected tooth silk.
