Power.In order to carry out the production of bellows at the scene, ripple cylinder device is needed to have the function of road transport, in the condition
Under, need ripple cylinder device to can satisfy collapsed transportable function.
Lifting folds the important component of adjustment mechanism integrated wavy metal cylinder device, directly affects mobile wave
The transport of line cylinder device.Integrated ripple cylinder device dump plaftorm debugging test link lifts the length of part up to 10 meters, parallel
It is 1.2 meters of lifting under quadrangular mechanism, advances 3 meters, lifting moiety by weight reaches 5 tons, and it is outstanding in one to lift beam after lifting
Arm state, fulcrum stress are larger.Under the conditions of existing, it is inconvenient which is adjusted, and there is very big security risk, equipment
Adjustment difficulty is big, and common method is difficult to meet the adverse circumstances of lifting, the process directly affect ripple cylinder device fold with
Transport, influences the further development of bellows items of equipment.In the dump plaftorm lifting debugging of ripple cylinder device, one is not taken
Safely and effectively mechanism regulation scheme, when in case of serious accident, consequence is hardly imaginable.Therefore, a symbol is designed
The dump plaftorm lifting debugging mechanism for closing bellows is very necessary.
Summary of the invention
The technical problem to be solved by the present invention is existing lifting mechanism adjusts inconvenience, equipment adjustment difficulty is big, exists very
Big security risk, to solve the above problems, providing a kind of bellows automatic lifting adjustment mechanism.
The object of the present invention is achieved in the following manner:
A kind of bellows automatic lifting adjustment mechanism, including extensible canopy and the lifting beam being arranged on extensible canopy, extensible canopy
It is connect between lifting beam by two connecting rods I and connecting rod II disposed in parallel, hydraulic cylinder, connecting rod II is also connected on connecting rod I
It is connect with parallelism adjusting device.
Parallelism adjusting device setting is on lifting beam.
Parallelism adjusting device include be arranged in lifting beam on adjustable plate, adjust front edge of board connect with trunnion, trunnion and
Connecting rod II connects, and the relative position of adjustable plate and trunnion is adjustable.
The front end of adjustable plate is provided with adjusting tooth I, and hangers is provided with corresponding adjusting tooth II with the junction of adjustable plate, hangs
Ear is bolted with adjustable plate.
Hook is connected on extensible canopy.
Compared with the existing technology, the present invention is connected with parallelism adjusting device on connecting rod II, for adjust connecting rod II with
The depth of parallelism of connecting rod I, improve lifting motor adjustment stability and safety, effective solution large overhanging beam lifting and folds
Adjust difficult one of key technical problem.

Specific embodiment
As shown in Figure 1-Figure 3, a kind of bellows automatic lifting adjustment mechanism, including extensible canopy 5 and setting are on extensible canopy
Lifting beam 7, connected between extensible canopy 5 and lifting beam 7 by two connecting rods I 4 and connecting rod II 6 disposed in parallel, on connecting rod I 4
It is also connected with hydraulic cylinder 2, connecting rod II 6 is connect with parallelism adjusting device.Parallelism adjusting device setting is on lifting beam.In parallel
Degree regulating device is used to finely tune the position of connecting rod II, guarantees the depth of parallelism of connecting rod II and connecting rod I, guarantees the levelness of lifting beam.
As shown in Fig. 2, parallelism adjusting device include be arranged in lifting beam 7 on adjustable plate 10,10 front end of adjustable plate with
Trunnion 8 connects, and trunnion 8 and connecting rod II 6 are hinged, and adjustable plate 10 and the relative position of trunnion 8 are adjustable.
The front end of adjustable plate 10 is provided with adjusting tooth I, and hangers 8 is provided with corresponding adjusting tooth with the junction of adjustable plate 10
II, hangers is connect with adjustable plate by bolt 9.Using trunnion and adjustable plate structure, improve lifting motor adjustment stability with
Safety, the effective solution large overhanging beam lifting key technical problem one of difficult with adjustment is folded.
Hook 3 is connected on extensible canopy.After I 4 pull-up of connecting rod, hook 3 hangs over connecting rod I and lifts the company of beam hydraulic cylinder 2
On outbound axis, for guaranteeing the position of lifting beam.
As shown in Figure 1, it is lifting movement that the tailstock pumping plant that hydraulic cylinder 2 lifts 7 rear portion of beam by being located at equipment, which provides pressure,
Pressure is provided, oil cylinder, which is shunk, pulls connecting rod I 4, and connecting rod I 4 and connecting rod II 6 constitute a parallelogram mechanism, and the mechanism is in liquid
Pull-up lifting beam 7 lifts under the action of cylinder pressure 2, such as Fig. 3 after lifting.After lifting in place, hydraulic cylinder 2 is automatically withdrawn into stroke most
Small, on extensible canopy 5, other end support lifting beam 7 is hung using hook 3 and is tightly located at connecting rod for connecting rod I 4 and II 6 one end of connecting rod at this time
The fixed lifting beam position of pin shaft at I 4, that is, complete the lifting of whole equipment.After the completion of whole equipment lifting, extensible canopy 5 is pushed
It travels forward, after being inserted into equipment, completes the lifting and folding of whole equipment.
During the equipment lifts, it is necessary to assure connecting rod I 4 and connecting rod II 6 are in a parallelogram like in Fig. 1
State, otherwise the connecting rod is trapezium structure, lifts beam front rake after causing lifting.It is trunnion 8 and 10 shape of adjustable plate shown in Fig. 2
At adjustment structure, trunnion is that daughter board and adjustable plate are fixed by 4 screws (11)；Adjustable plate is motherboard, is welded with supporting beam
Together.Ripple cylinder device lifting test link, adjusting trunnion first and excessively adjusting distance between plates is that after hitting exactly, screw is consolidated
It is fixed securely to check whether double leval jib state is parallel in lifting process, and lift the problem of beam front is with the presence or absence of decline；If gone out
It is existing, by trunnion and excessively adjust plate spacing adjustment, the foundation of adjustment are as follows: in Fig. 3, after the completion of lifting, lift the left side of beam 7 with
When theoretical size is relatively low, after can adjusting downwards the tooth of depth of parallelism adjustable plate relative to trunnion, lifting beam with double leval jib is rotation
After point is rotated clockwise, left side is increased, and right side reduces, until being adjusted to suitable position；Left side and reason when lifting beam 7
When higher by size, the tooth of depth of parallelism adjustable plate can be adjusted upward relative to trunnion, lifting beam with double leval jib is that rotation clicks through
After row rotates clockwise, left side is reduced, and right side increases, until being adjusted to suitable position.Adjustment and the company in four-bar mechanism
The distance of bar I 4, makes it meet parallelogram mechanism.After being adjusted in place, by trunnion and transition plate firm welding, lifting is adjusted
Process finishes, and meets test requirements document.
The invention has the benefit that
(1) the configuration of the present invention is simple improves the convenience and reliability of bellows equipment debugging, after being convenient for operation
The development of continuous work is laid a good foundation；(2) safety in bellows lifting and crease-flex test process is improved, is quickly adjusted full
Sufficient equipment index lays the foundation to the road transport of ripple cylinder device；(3) reduce unnecessary test in equipment adjustment process
Process reduces a large amount of work, more convenient to complete equipment operation.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without depart from that overall concept of the invention, several changes and improvements can also be made, these also should be considered as of the invention
Protection scope.
