The template of assembled box culvert 13, for directly pouring prefabricated assembled box culvert 13 on overturning platform 1.Thus scheme is being overturn
It is not required to hoisting construction completely in the process, operates more convenient.
Embodiment 8:
On the basis of embodiment 1 ~ 6, in optional scheme such as Fig. 5 or the template 24 of prefabricated assembled box culvert 13 is equipped with
Lifting lug, when needing to overturn, by prefabricated assembled box culvert 13 and 24 integral hoisting of template on overturning platform 1.Thus scheme, just
In realizing streamlined operation, the quantity of equipment for supporting patient with burn can be reduced.
Embodiment 9:
For embodiment 3 ~ 6, in preferred scheme such as Fig. 4, the pushing end oil circuit of the first overturning oil cylinder 7 and sliding oil cylinder 2 is equipped with
Throttle valve 18 and the unidirectional valve group 17 of commutating retract end oil circuit and are equipped with throttle valve, pushing end oil circuit and retract and hold oil circuit and reversal valve
19 one end connection, the other end of reversal valve 19 are connect with hydraulic pump 22 and oil return circuit；Thus scheme makes the first overturning oil cylinder
7 can realize back pressure in pushing or pulling on operating condition, and the unidirectional valve group 17 that can be commutated by control realizes speed control.Sliding
The control oil circuit of oil cylinder 2 is identical as the control oil circuit of the first overturning oil cylinder 7, is omitted in Fig. 4.It is further preferred that
Displacement sensor is equipped between sliding oil cylinder 2, the first overturning oil cylinder 7 and the cylinder body and piston rod of the second overturning oil cylinder 10, with
Monitor the extension elongation of piston rod.
The pushing end oil circuit of second overturning oil cylinder 10 is equipped with throttle valve, and pushing end oil circuit is connect with one end of switching valve 20,
The other end of switching valve 20 is connect with hydraulic pump and oil return circuit；Thus scheme can simplify oil channel structures, and pass through switching valve
20 can also control speed when overturning platform 1 is transferred.
By taking the optimal case in such as Fig. 1 ~ 4 as an example, mode of operation of the invention is illustrated, prefabricated assembled box culvert is worked as
13 intensity reach requirement, and when needing to overturn, as shown in fig. 1, switching valve 20 is acted, and hydraulic pump movement enters hydraulic oil
The pushing end of second overturning oil cylinder 10, the pushing end in this example are rodless cavity, and the piston rod of the second overturning oil cylinder 10 stretches out, and make the
Two rotating support plates 9 are rotated around shaft 5, and overturning platform 1 rotates with it.Reversal valve 19 in the oil circuit of first overturning oil cylinder 7
Simultaneously operation, the unidirectional valve group 17 that commutates at this time are in unidirectional fuel-displaced position, and hydraulic oil enters retracting for the first overturning oil cylinder 7
It holds, the end that retracts in this example is rod chamber, and the piston rod of the first overturning oil cylinder 7 retracts；The piston rod of sliding oil cylinder 2 retracts, sliding
Upward sliding, rotary angle transmitter 16 monitor the corner of shaft 5 to dynamic seat 3 simultaneously, cooperate the movement of each oil cylinder consistent.Work as overturning
Platform 1 is more than equalization point, i.e. overturning platform 1 starts 7 direction of the first overturning oil cylinder into Fig. 1 and falls, 7 nothing of the first overturning oil cylinder
The oil pressure of rod cavity gradually increases, and 22 speed of hydraulic pump is lowered at this time, and throttle valve 18 controls the velocity interpolation pressure of hydraulic oil outflow
Power controls, and in necessary situation, when reversal rate is excessively high, speed control is realized in the direction for passing through the unidirectional valve group 17 of control commutation.When
Overturning platform 1 is totally turned over, and the first overturning oil cylinder 7 and sliding oil cylinder 2 at this time is fully retracted.
After prefabricated assembled box culvert 13 hangs overturning platform 1, the piston rod of the first overturning oil cylinder 7 and sliding oil cylinder 2 is stretched
Out, overturning platform 1 is overturn again, after overturning platform 1 and the second rotating support plate 9 contacts, the work of the second overturning oil cylinder 10
Stopper rod slowly retracts.It is ready the overturning lower subjob of platform 1.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this Shen
Please in embodiment and embodiment in technical characteristic in the absence of conflict, can mutual any combination.Guarantor of the invention
The technical solution that range should be recorded with claim is protected, being equal for technical characteristic replaces in the technical solution recorded including claim
Changing scheme is protection scope.Equivalent replacement i.e. within this range is improved, also within protection scope of the present invention.
