Description
Technical field
The utility model provides a kind of hydraulic adjustment wheel of shield machine, belongs to shield-tunneling construction field.
Background technique
The wheel that shield machine uses currently on the market uses traditional form, i.e. car body is directly anchored on wheel, belongs to
Rigid connection, structure is simple, can not adjust height, and if entire car body wheel also can not freely turn when encountering turning
It is curved, it is unable to satisfy the demand in particular job, especially under the operating condition of underground complexity.
Summary of the invention
The technical issues of the utility model solves above-mentioned technical problem and provides a kind of hydraulic adjustment wheel of shield machine, solves
It is shield locomotive wheel height adjustment problem, realizing shield locomotive wheel can control lift adjustment, solve between the car crossbeam of front and back
Height quickly adjust with connect, rotate with the variation of pitching movement control, mating height of the carbody is not easy after solving shield machine
The turning when deficiency of adjustment, climbing when the angle too small of car body, rotation is excessive and the bring part sliding that works long hours
Surface wear seriously cause equipment must shutdown maintenance significant trouble, ensure that shield machine can continuously uninterruptedly stable progress
Excavation operation.
The utility model solves the technical solution that technical problem uses:
A kind of hydraulic adjustment wheel of shield machine, it includes that rear car wheel assembly, the first front wheel assembly and the second front vehicle wheel are total
At, rear car wheel assembly and the first front wheel assembly are equipped with wheel stand, hydraulic cylinder assembly is equipped between wheel stand and car body,
The hydraulic cylinder assembly includes the cylinder body being arranged on wheel stand, and piston is equipped in cylinder body, and piston upper end connects equipped with car body
Fitting is used for connection body on car body connector, and the piston can slide up and down in cylinder body, and piston can be in cylinder body
Rotation.
Above-mentioned cylinder body includes ontology, is pillar in the middle part of ontology, ontology upper end side is equipped with side plate, between ontology and pillar
Form cavity；Specific identical shape between the piston and cavity, piston can slide in the cavity, and can revolve around pillar
Turn.
It is equipped with positive stop lug boss on the outside of above-mentioned pillar upper end, is equipped with seal groove, seal groove at positive stop lug boss and piston cooperation
It is interior to be equipped with sealing ring.
Above-mentioned side plate is bolted on wheel stand, passes through bolt between the piston and car body connector
It is connected.
The utility model has the beneficial effects that
1, when shield machine is tunneled in construction in line with the drawings to when needing to turn round, this hydraulic adjustment wheel can both keep original
When supporting constant, driving turning needs can also be met；When shield machine driving when encounter river, culvert or with other subway tunnels
When confluce, when needing to be tunneled downwards at a certain angle, it can control and adjust oil cylinder stroke to control height of the carbody；When more
It crosses after the above barrier and is kept at an angle when being tunneled upwards again, it can also be by adjusting wheel height to meet
Driving demand guarantees the work driving height before equipment may return to, continues Shield digging operation；
2, the application efficiently solves the convenience, reliable of shield railcar body both ends connection, meets in underground tunneling construction
The case where Shi Wufa controls car body reduces the drawbacks of equipment should not be safeguarded in underground excavation operation, alleviates operation
The workload of personnel, the working strength for reducing operator.
Detailed description of the invention
It is illustrated below in conjunction with attached drawing with embodiment
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the detail of construction of hydraulic cylinder assembly.
Specific embodiment
Referring to attached drawing 1-2, a kind of hydraulic adjustment wheel of shield machine, it includes rear car wheel assembly 1, the first front wheel assembly 2
With the second front wheel assembly 3, rear car wheel assembly and the first front wheel assembly are equipped with wheel stand 4, wheel stand and car body it
Between be equipped with hydraulic cylinder assembly, the hydraulic cylinder assembly includes the cylinder body 5 being arranged on wheel stand, piston 6 is equipped in cylinder body,
Piston upper end is equipped with car body connector 7, and connection body is used on car body connector, and the piston upper in cylinder body can glide
It is dynamic, and piston can rotate in cylinder body.
Preferably, the cylinder body includes ontology 8, is pillar 9 in the middle part of ontology, and ontology upper end side is equipped with side plate 10, this
Cavity 11 is formed between body and pillar；Specific identical shape, piston can slide in the cavity between the piston and cavity,
And it can be rotated around pillar.
Preferably, it is equipped with positive stop lug boss 12 on the outside of the pillar upper end, is equipped with sealing at positive stop lug boss and piston cooperation
Slot, seal groove is interior to be equipped with sealing ring.
Preferably, the side plate is bolted on wheel stand, between the piston and car body connector
It is connected by bolt.
The hydraulic adjustment wheel of shield machine can carry out height tune to car body mating after shield machine using the hydraulic cylinder at center
It is whole, can also be according to needs to be tunneled in hole, the angle of the anterior and posterior height of mating car body controls after control, to meet downwardly and upwardly
Excavation, traction need.
The protection scope of the utility model is not limited to the above embodiments, it is clear that those skilled in the art can be right
The utility model carries out various changes and deformation without departing from scope and spirit of the present invention.If these changes and deformation belong to
