Description
Technical field
The invention belongs to mechanical engineering technical field, particularly relate to a kind of long tube semitrailer gas cylinder lifting crossover device.
Background technology
Produce the production line of high pressure gas long pipe semitrailer gas cylinder, the transport of gas cylinder and transhipment main by longitudinal roller-way,
Laterally shift fork and overhead traveling crane handling realize.Gas cylinder all of non-horizontal continuative transport sky to be used in production line
Car, causes overhead traveling crane use frequency in gas cylinder production line the highest, and often occurring stopping work waits the situation of overhead traveling crane.And single
Gas cylinder is about 12m, external diameter φ 711mm, weight 4.8t, and common hanging device is difficult to meet use requirement, and overhead traveling crane hangs
The efficiency of dress is also far below first two mode；Therefore reduce the dependence to overhead traveling crane, become the judgement bar that gas cylinder production line is good and bad
One of part.
Longitudinal roller-way on gas cylinder production line and horizontal shift fork gas cylinder transport it sometimes appear that situation about intersecting, but longitudinal roller
Road and horizontal shift fork are all basic on a height, for realizing transporting continuously, need to lift horizontal shift fork gas cylinder, across
Cross longitudinal roller-way, then put down.For solving this problem, generally make special hanging apparatus in crossover sites or pass through sky
Car lifting realizes.Hanging apparatus needs to take bigger ground space position and locus in midair, need to be equipped with support
System and translating trolleys and lifting mechanism two overlap telecontrol equipment, and cost is higher, not only cause ground space narrow and small, also
Affect operation and the lifting of overhead traveling crane.Use overhead traveling crane lifting can cause taking for a long time of overhead traveling crane, less economical.
Summary of the invention
It is an object of the invention to provide a kind of long tube semitrailer gas cylinder lifting crossover device, it is achieved that gas cylinder steadily lifts,
Translate, slowly fall, it is ensured that the Automatic continuous of production line runs, and is not take up exceptional space, simple in construction, low cost.
The present invention includes mechanical system, hydraulic system and automatic control system.
Mechanical system includes: support 1, lifting pusher dog 2, hydraulic cylinder 3, decline pusher dog 4, former horizontal shift fork roller-way 5,
Ramp 6.On support 1, plane makes inclined plane, makes gas cylinder 7 can be rolled to lower under gravity (by lifting pusher dog
Arrive at 2 and decline at pusher dog 4)；Make 4 altogether on two supporting leg base plates of support 1 and inside upper corners and connect knot
Structure, is respectively intended to connect 2 hydraulic cylinder afterbodys and lifting pusher dog 2 and decline the fixing end of pusher dog 4.Lifting pusher dog 2
Connecting with inside support 1 upper corners with declining the fixing end of pusher dog 4, middle part connects with hydraulic cylinder 3 head.Hydraulic cylinder 3
Afterbody is connected on the base plate of support 1, and head connects with the middle part of lifting pusher dog 2 and decline pusher dog 4 respectively.Former horizontal stroke
To shift fork roller-way 5, itself there is certain gradient, make the reliable inclination gravity of gas cylinder 7 to the groove lifted in the middle part of pusher dog 2
Place；Declining after pusher dog 4 puts down gas cylinder 7, can roll on themselves to relatively low distant place.Ramp 6 is installed on decline pusher dog 4
Put down at gas cylinder 7, be welded on former horizontal shift fork roller-way 5, initially roll speed guaranteeing that gas cylinder 7 can obtain after putting down
Degree.
Described lifting pusher dog 2 is realized 2 functions by inside and outside 2 circular arcs, and middle part Inner arc is used for lifting gas cylinder 7, protects
In card lifting process, gas cylinder 7 is steady, and arrival highest point rear arc should be slightly above support 1 highest point makes gas cylinder 7 automatic
It is rolled on support 1；Head external arc acts the effect stopping gas cylinder 7, is lifting during pusher dog 2 hoists and is arriving
When reaching the position of highest point, follow-up gas cylinder to be lifted 7 is prevented to be rolled into the underface of lifting pusher dog 2 and cause lifting pusher dog 2
Can not normal return.Decline the function of Inner arc in the middle part of pusher dog 4 and, with lifting pusher dog 2, realize decline process by Inner arc
Middle gas cylinder 7 does not drops.
Described hydraulic cylinder 3, afterbody jointing all band oscillating bearings, not only improve bearing capacity, and have from profit
Sliding effect, to adapt to the low speed oscillations motion of hydraulic cylinder jointing.Because possessing oscillating bearing, hydraulic cylinder head is with lifting
Rising pusher dog 2 and decline the link of pusher dog 4, using standard bearing pin and split pin, afterbody uses with the link of support 1 base
Standard bearing pin and split pin.
Described lifting pusher dog 2, decline the fixing point that pusher dog 4 is whole lifting process with support 1 junction, be also
Big stress point.Using self-control axle 10 to connect, support 1 coaxial 10 does not relatively rotates, by embedding in axle 10 herein
Enter fixed dam 11 to realize, thus can reduce the abrasion of support 1 fixed structure and improve robust motion.Lifting pusher dog
2 can relatively rotate with declining pusher dog 4 coaxial 10, add cu bearing liner 12 and process lubricating oil on axle 10 on axis hole
Hole is to realize sliding lubrication and reducing abrasion；Cu bearing liner 12 and axle 10 should have bigger contact length, to prevent from lifting
Rise pusher dog 2 and decline double swerve in pusher dog 4 motion.
Hydraulic system critical component includes: hydraulic pressure tetrad syncmotor 14, solenoid directional control valve 15, one-way speed-regulating valve 16.
Solenoid directional control valve 15, one-way speed-regulating valve 16 and hydraulic pressure tetrad syncmotor 14 it is sequentially connected with on the oil supply loop of Hydraulic Station,
Hydraulic pressure tetrad syncmotor 14 has four oil-outs, is connected to the oil-in of four hydraulic cylinders 3；On oil return circuit
The oil return opening of four hydraulic cylinders 3 is first pooled at one, then is sequentially connected with one-way speed-regulating valve 16 and solenoid directional control valve 15.Liquid
Pressure tetrad syncmotor 14 makes the hydraulic cylinder of 4 parallel operations open simultaneously, arrives simultaneously and specifies position, it is ensured that 4
Lifting the pusher dog 2 and synchronous operation of 4 decline pusher dogs 4, prevent hydraulic cylinder action asynchronous cause gas cylinder 7 to tilt and
Break away.The lifting of solenoid directional control valve 15 system under automated control control realization and down maneuver.One-way speed-regulating valve 16 is used for
Adjust the speed of service of hydraulic cylinder 3.
Automatic control system detection part: include 6 photoelectric limit switch and 1 TV monitor system.6 photoelectricity limits
The position signalling of the on-the-spot gas cylinder of bit switch conveying and hydraulic cylinder 3 is to PLC (programmable logic controller (PLC)), by PLC control
Hydraulic cylinder 3 realizes course of action；TV monitor system facilitates whether operator's monitoring site at any time has abnormal conditions to send out
Raw.Wherein, 4 limit switches judge lift pusher dog 2 and decline whether pusher dog 4 has arrived at highest and lowest work respectively
Make position, further work could be carried out to facilitate program to judge；Remaining limit switch one judges whether to need to lift gas
Bottle 7, another judges the operating position of the gas cylinder 7 the most already out decline pusher dog 4 put down, program when condition is unsatisfactory for
Must not run.
It is an advantage of the current invention that and solve longitudinal roller-way and horizontal shift fork rail junction transport gas cylinder with relatively low cost
Problem, be not take up any exceptional space, it is achieved that the lifting of the automatic steady of gas cylinder, translation, slowly fall, it is ensured that
High pressure gas long pipe semitrailer gas cylinder production line continuously and automatically runs.
