Description
Technical field
The invention belongs to field bridge cart jacking cylinder limiting device technical fields, and in particular to a kind of bridge cart jacking oil
Cylinder limiting device.
Background technique
Field bridge is tire construction for loading and unloading place container, large vehicle walking wheel, and big mechanism of car has turning function, and configures
There are four jacking cylinders, with tire when turning to avoid cart and ground friction.When bridge needs to turn on the spot, jacking cylinder is jacked up
Field bridge, tire are detached from ground.
In order to realize the automatic control to steering while ensure equipment safety, each jacking cylinder is equipped with jacking, synthlipsis
Location sensitive limit, by a gag lever post with oil cylinder telescopic moving, limit signal is answered in the sense of access.Operation for jacking cylinder
There are two types of control mode: drivers' cab automatically controls and ground manually control (by the rotary switch of drivers' cab can switch this two
Kind control mode).
When selecting drivers' cab to automatically control, in operation process, equipment can the synthlipsis state to oil cylinder detect, if having
For oil cylinder not in retracted mode, then will start Electric Machine at Pumping Station retracts oil cylinder, to avoid oil cylinder tenesmus bring security risk.When
When selection ground manually controls, then do not have above functions.Therefore, jacking cylinder is intact very heavy to equipment use and safety
It wants.
However, jacking cylinder often will appear the phenomenon that fractureing from gag lever post root during bridge use on the scene.If not and
The Shi Faxian problem, the gag lever post to fracture easily scratch oil cylinder piston cylinder body.When oil cylinder piston is scraped off, oil cylinder can not be normal close
Envelope, has oil leakage phenomenon, must replace oil cylinder in time.Piston is repaired at this time, and more demanding to maintenance skills, intra-company's maintenance is difficult
To guarantee the reliability used, entrust to professional external company's maintenance cost expenditure higher.Gag lever post is had no progeny, can not be to jacking oil
The synthlipsis of cylinder carries out drivers' cab automatic control, in operation process equipment can not the synthlipsis state to oil cylinder detected automatically, deposit
Security risk brought by dropping in oil cylinder pallet.In addition, gag lever post is had no progeny, can generally be distorted deformation, and when maintenance need to tear open
Lower limit bar is adjusted, and is then re-soldered on oil cylinder, and because gag lever post deforms, disassembly is often relatively difficult, is deformed simultaneously
Gag lever post be also difficult to be adjusted to perfect condition, inconvenience reinstalls welding, also influences using effect.With duration of service
Growth, which seems more and more prominent.
Summary of the invention
A kind of bridge cart jacking cylinder limiting device is provided it is an object of the invention to solve above-mentioned technical problem.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of bridge cart jacking cylinder limiting device, including be set on the piston rod of jacking cylinder can be around the work
The collar assemblies that stopper rod is rotated, the collar assemblies include the upper lantern ring being mutually stacked together and lower collar, the upper set
Ring connects the gag lever post of the jacking cylinder, and the lower collar can prevent the upper lantern ring along living after being mounted on the piston rod
Stopper rod axial movement.
The gag lever post is L shape.
The gag lever post and the upper lantern ring welding or socket connection.
The upper lantern ring and the diameter of lower collar are greater than the diameter 1mm of the piston rod.
It includes the lantern ring that can be rotated around the piston rod being set on the piston rod of jacking cylinder that the present invention, which passes through,
Component, the collar assemblies include the upper lantern ring being mutually stacked together and lower collar, and the upper lantern ring connects the jacking cylinder
Gag lever post, the lower collar can prevent the upper lantern ring from moving axially along piston rod after being mounted on the piston rod, can be with
Using the rotation of collar assemblies, correspondingly rotate gag lever post, to solve the problems, such as current gag lever post fracture.
Detailed description of the invention
Fig. 1 illustrates the schematic diagram of field bridge cart jacking cylinder limiting device of the invention.
Specific embodiment
In the following, in conjunction with example, property feature and advantage is further described for the essence of the present invention, but the present invention not office
It is limited to listed embodiment.
It is shown in Figure 1, a kind of bridge cart jacking cylinder limiting device, the piston rod including being set in jacking cylinder 10
On the collar assemblies that can be rotated around the piston rod, the collar assemblies include the upper lantern ring 20 that is mutually stacked together with
Lower collar 30, the upper lantern ring connects the gag lever post 40 of the jacking cylinder, after the lower collar is mounted on the piston rod
It can prevent the upper lantern ring from moving axially along piston rod.
In specific implementation, in the present invention, the gag lever post is L shape.
In specific implementation, in the present invention, the gag lever post and the upper lantern ring welding or socket connection.It can certainly
It is other connection types, such as the mode of connection is attached, the connection type of the gag lever post and the jacking cylinder can also
It is specific unlimited to be welding or other connection types.
Specifically, the upper lantern ring, lower collar are respectively two semicircular rings, pass through bolt lock after covering on the piston rod
Tightly form a closed loop configuration.
Preferably, in the present invention, the diameter of the upper lantern ring and lower collar is greater than the diameter 1mm of the piston rod.In this way,
When being installed on piston rod, can be freely rotated;And two set ring width superpositions just occupy section below piston rod, it will not
Upper and lower play.
When installation, upper lantern ring, lower collar are fixed on to the bottom of cylinder body, the lantern ring of lower section is used to limit the lantern ring of top
It moves up and down, the lantern ring of top is used to connect with gag lever post.So realize that gag lever post can rotate on cylinder body with lantern ring, thus
Eliminate the problem of former gag lever post fixed form is brought
Gag lever post of the present invention is connect by collar assemblies with jacking cylinder piston rod, can be freely rotated on the piston rod,
And move up and down piston rod and be to ensure that and accurately sense the limit of corresponding position, using effect is good.
Collar assemblies of the invention also can be generalized in similar induction structure mechanism and be used to be transformed consolidating for induction gag lever post
Determine mode, eliminates defect existing for former design.
The present invention may be implemented do not disassembling oil cylinder under the premise of keeping jacking cylinder gag lever post function constant
And the fixed form of oil cylinder gag lever post is transformed on the basis of the original components of reservation or structure.
It includes the lantern ring that can be rotated around the piston rod being set on the piston rod of jacking cylinder that the present invention, which passes through,
Component, the collar assemblies include the upper lantern ring being mutually stacked together and lower collar, and the upper lantern ring connects the jacking cylinder
Gag lever post, the lower collar can prevent the upper lantern ring from moving axially along piston rod after being mounted on the piston rod, can be with
Using the rotation of collar assemblies, correspondingly rotate gag lever post, to solve the problems, such as current gag lever post fracture.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
