Description
Technical field
The present invention relates to pipeline end face groove processing technique fields, are cut in particular to a kind of pipeline end face groove
Equipment starting protection system.
Background technology
With the raising that country requires Welding Quality for Long Distance Pipeline, the promotion of pipe line steel strength grade and manpower at
This is greatly improved, and all positon automation long distance pipeline welding is used more and more, and long distance pipeline will realize automatically
Weldering, the first step are exactly that must solve the problems, such as the standard technology retaining wall on slope of two end faces of long distance pipeline, but pipeline on the market
For end face groove equipment without the defencive function for rotating big disk startup rotation, i.e. worker stretches out fixed steel pipe in the boots that will not rise,
And no protective device by about can equally start the big disc spins of rotation in the case of putting down, to be easy to happen peace
Full accident.
Invention content
The purpose of the present invention is to provide a kind of pipeline end face groove cutting equipment starting protection systems, have solved existing skill
The deficiency of art.
Purpose to realize the present invention, the technical solution used for：A kind of pipeline end face groove cutting equipment starting protection system
System, including fuel tank, the boots lift valve that rises, inserted valve, the big plate hydraulic motor of rotation, motor in-line and rise what boots stretched out for control
Rise cylinder lifting cylinder, which is characterized in that further includes left side hydraulic valve and the right side of protective device lower end about being located at
Hydraulic valve；The boots that rise of the boots lifting cylinder that rises are connect into and out of oil circuit with the boots lift valve that rises；The control in-line of the inserted valve
It is connected to positioned at the boots in-line that rises to rise between boots lifting cylinder and the boots lift valve that rises, and left side hydraulic valve and right side hydraulic valve string
Connection is arranged on the control in-line of inserted valve；The motor in-line respectively with inserted valve and the big plate hydraulic motor of rotation into
Hydraulic fluid port is connected to.
Further, the inserted valve is connected to fuel tank with the vent line for rotating big plate hydraulic motor.
Further, the motor in-line being connected to oil inlet that is rotating big plate hydraulic motor is equipped with check valve.
Further, the boots vent line connection fuel tank that rises of the boots lifting cylinder that rises.
Using the invention has the advantages that：
It allows and rotates big disc spins, i.e., must rotate big plate hydraulic motor work just can be with the oil of motor in-line, in inserted valve
When in off position namely opening state, oil directly can flow back to fuel tank by inserted valve, that is to say, that as long as inserted valve
It does not close, rotating big plate hydraulic motor would not rotate.Only when inserted valve is closed, at this point, motor in-line
Oil can just flow through the big plate hydraulic motor of rotation, drive and rotate big disc spins.And the present invention stretches out fixed steel pipe in the boots that rise（Rise boots
Lift valve is opened）, about protective device put down touching left and right side hydraulic valve switch so that left and right side hydraulic valve is opened
In the case of complete control in-line oil inlet, so that inserted valve is closed, at this moment rotating big plate hydraulic motor could work, to significantly
Improve the safety of pipeline end face groove processing.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of pipeline end face groove cutting equipment starting protection system provided by the invention.
Specific implementation mode
The present invention is described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
The shown pipeline end face groove cutting equipment starting protection systems provided by the invention of Fig. 1, including fuel tank 10, rise
Boots lift valve 9, inserted valve 3, inserted valve control in-line 4 rotate big plate hydraulic motor 1, motor in-line 2, for controlling the boots that rise
Stretch out rise cylinder lifting cylinder 8 and about being located at protective device lower end left side hydraulic valve 5 and right side hydraulic valve
6；The boots that rise of the boots lifting cylinder 8 that rises are connect into and out of oil circuit with the boots lift valve 9 that rises；The control in-line 4 of the inserted valve with
It is connected to positioned at the boots in-line 7 that rises to rise between boots lifting cylinder 8 and the boots lift valve 9 that rises, and left side hydraulic valve 5 and right side hydraulic valve
6 are arranged in series on the control in-line 4 of inserted valve；The motor in-line 2 respectively with inserted valve 3 and rotation deep bid hydraulic pressure horse
Oil inlet up to 1 is connected to；The inserted valve 3 is connected to fuel tank 10 with the vent line for rotating big plate hydraulic motor 1；Described and rotation
The motor in-line of the oil inlet connection of big plate hydraulic motor 1 is equipped with check valve 11；The boots that rise of the boots lifting cylinder 8 that rises are fuel-displaced
Road 12 is connected to fuel tank 10.
It first has to allow and rotates big disc spins, i.e., must rotate the work of big plate hydraulic motor 1 just can be with motor in-line 2
For oil when inserted valve 3 is in off position namely opening state, oil directly can flow back to fuel tank 10 by inserted valve 3, also
As long as being to say that inserted valve 3 is not closed, rotating big plate hydraulic motor 1 would not rotate.Only when inserted valve 3 is closed,
At this point, the oil of motor in-line 2 can just flow through the big plate hydraulic motor 1 of rotation, drives and rotate big disc spins.
The present invention, which first has to open, to rise boots lift valve 9, and 8 oil inlet of the boots lifting cylinder work that makes to rise boots of completing to rise stretch out fixed steel
Pipe；Then protective device about putting down, so that it is touched the switch of left and right side hydraulic valve respectively makes left side hydraulic valve 5 and the right side
Side hydraulic valve 6 is opened, and at this moment a part of oil in the boots in-line 7 that rises is entered by controlling in-line 4 in inserted valve 3, is made
Inserted valve 3 is closed, and after inserted valve 3 is closed, the oil in motor in-line 2 can just flow to the big plate hydraulic motor 1 of rotation, at this moment revolve
Turning big plate hydraulic motor 1 could work, therefore the present invention can be achieved only to stretch out fixed steel pipe in the boots that rise（Rise boots lift valve 8
It opens）, about protective device put down switch the case where making left and right side hydraulic valve open of touching left and right side hydraulic valve
Under, rotating big plate hydraulic motor 1 could work, to substantially increase the safety of pipeline end face groove processing.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
