Abstract
The utility model discloses an oil pipe burst safety protecting device of a hydraulic diaphragm wall grab, which comprises two long hoses (8, 2); both ends of the long hoses (8, 2) are provided with hydraulic control check valves. The utility model is an oil pipe burst protecting device of a hydraulic diaphragm wall grab, which can cut off an oil circuit to prevent hydraulic oil from being leaked when a hydraulic oil pipe bursts.
Description
Technical field
The utility model relates to a kind of oil pipe explosion safety guard, particularly relates to a kind of continuous wall hydraulic grab oil pipe explosion safety guard.
Background technology
Continuous wall hydraulic grab drives the hydraulic oil pipe explosion because the effect of multiple factor may make to grab bucket in work progress.If untimely taking measures, hydraulic efficiency pressure system may continue fuel feeding gives and hoists, descends and loop such as revolution, causes hydraulic oil to leak even fatal personal injury.At present, the unspecial oil pipe explosion safety guard that is provided with on the continuous wall hydraulic grab hoisting crane.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly can cut off the continuous wall hydraulic grab oil pipe explosion safety guard that oil circuit prevents that hydraulic oil from leaking when grab bucket drives the hydraulic oil pipe explosion.
In order to solve the problems of the technologies described above, the continuous wall hydraulic grab oil pipe explosion safety guard that the utility model provides comprises two Great Wall Software's pipes, and it is characterized in that: fluid-controlled cut-off valve is equipped with at the two ends at described two Great Wall Software's pipes respectively.
The control end of the fluid-controlled cut-off valve that the end that described two Great Wall Software's pipes close on fuel tank is provided with is connected with electromagnetic valve, the control line of described electromagnetic valve is connected with electronic controller, is provided with the pressure sensor that is electrically connected with described electronic controller on described two Great Wall Software's pipes.
Adopt the continuous wall hydraulic grab oil pipe explosion safety guard of technique scheme; in the process of continuous wall grab work; any root oil circuit booster in two Great Wall Software's pipes no matter; system can detect automatically; and cut off the working connection fuel feeding automatically, and reclaim remaining hydraulic oil in most of pipeline.
In sum, the utility model is a kind ofly can cut off the continuous wall hydraulic grab oil pipe explosion safety guard that oil circuit prevents that hydraulic oil from leaking when grab bucket drives the hydraulic oil pipe explosion.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, first Great Wall Software pipe 8 ends that close on hydraulic grab are provided with first fluid-controlled cut-off valve 9, the input of first fluid-controlled cut-off valve 9 is managed from first Great Wall Software, be output as the oil cylinder on the hydraulic grab, second Great Wall Software pipe 2 ends that close on hydraulic grab are provided with second fluid-controlled cut-off valve 1, the input of second fluid-controlled cut-off valve 1 is managed from second Great Wall Software, be output as the oil cylinder on the hydraulic grab, the 3rd fluid-controlled cut-off valve 6 that first Great Wall Software pipe 8 ends that close on fuel tank are provided with, the control end of the 3rd fluid-controlled cut-off valve 6 is connected with first electromagnetic valve 5, the 4th fluid-controlled cut-off valve 3 that second Great Wall Software pipe 2 ends that close on fuel tank are provided with, the control end of the 4th fluid-controlled cut-off valve 3 is connected with second electromagnetic valve 4, the control line of first electromagnetic valve 5 and second electromagnetic valve 4 is connected with electronic controller, is provided with the pressure sensor 7 that is electrically connected with electronic controller on pipe 8 and second Great Wall Software of first Great Wall Software pipe 2.
Referring to Fig. 1, during normal operation, first fluid-controlled cut-off valve 9 and second fluid-controlled cut-off valve 1 are operated in right position, and fluid is unimpeded.In case 2 explosion decompressions are managed by pipe 8 or second Great Wall Software of first Great Wall Software, then corresponding first fluid-controlled cut-off valve 9 or second fluid-controlled cut-off valve 1 are operated in position, a left side, and oil circuit is shut, and the fluid in the oil cylinder can not flow backwards.During normal operation, first electromagnetic valve 5 and second electromagnetic valve 4, passage wherein is open-minded, the control oil of the 3rd fluid-controlled cut-off valve 6 and the 4th fluid-controlled cut-off valve 3 spools one end communicates with fuel tank, the operation pressure that this moment, first Great Wall Software pipe, 8 and second Great Wall Software managed in 2 impels the 3rd fluid-controlled cut-off valve 6 and the 4th fluid-controlled cut-off valve 3 to be operated in the position of opening, and oil circuit is unimpeded.In case 2 explosion decompressions are managed by pipe 8 or second Great Wall Software of first Great Wall Software, the output signal that then is loaded on the pressure sensor 7 of hose line changes makes win electromagnetic valve 5 and second electromagnetic valve, 4 dead electricity through electronic controller, disconnect with the passage of fuel tank, in a short period of time, the 3rd fluid-controlled cut-off valve 6 and the 4th fluid-controlled cut-off valve 3 spools obtain hydro-cushion, this moment, the 3rd fluid-controlled cut-off valve 6 and the 4th fluid-controlled cut-off valve 3 were operated in the position of locking under the effect of spring force, and fluid is no longer exported.
In the process of continuous wall grab work, no matter be that 2 oil circuit boosters are managed by pipe 8 or second Great Wall Software of first Great Wall Software, system can detect automatically, and cuts off the working connection fuel feeding automatically, and reclaims remaining hydraulic oil in most of pipeline.
