In order to solve the technical problem, the utility model discloses a following technical scheme:
the anti-oil injection device for the hydraulic oil pipe explosion comprises a sleeve pipe sleeved outside the hydraulic oil pipe and a transition oil tank communicated with the sleeve pipe through a first connecting pipe, wherein the transition oil tank is communicated with a hydraulic oil tank of a hydraulic system through a second connecting pipe; and two ends of the sleeve are respectively fixed on the pipe joints at the corresponding ends of the hydraulic oil pipe in a sealing manner.
From this, when hydraulic pressure oil pipe bursts the pipe and takes place, intraductal hydraulic oil sprays and goes out from hydraulic oil pipe in the twinkling of an eye, because sheathed tube blockking and collection effect, hydraulic oil pipe bursts the pipe or the hydraulic oil that the seepage came out has flowed back to equipment hydraulic tank through connecting pipe and transition oil tank, can not contact with the interior high temperature spare parts such as engine of equipment cabin, thereby prevented the emergence of conflagration phenomenon, and reduced the loss of the hydraulic oil quantity in the hydraulic oil tank that produces because of bursting, hydraulic components such as hydraulic oil pump that the lack of oil leads to can not appear in equipment hydraulic tank because of the phenomenon of bursting simultaneously also can not damage the phenomenon because of the hydraulic pressure components such as pipe-explosion phenomenon.
As a further improvement of the above technical solution:
the two ends of the sleeve are retracted inwards to form sealing parts in interference fit with the corresponding pipe joints, and the sealing parts are fixed with the corresponding pipe joints through fixing clamps.
An opening for communicating the inner cavity of the sleeve with the first connecting pipe is formed in the outer wall of the middle of the sleeve, and the first connecting pipe is connected with the inner wall of the sleeve in a sealing mode.
A first detection mechanism is inserted into the pipe wall of the sleeve, and hydraulic oil splashed to the first detection mechanism after the pipe is burst through the hydraulic oil pipe can trigger the first detection mechanism. When the first detection mechanism is triggered, the first detection mechanism feeds back a tube explosion signal to the equipment control system, and the equipment stops working immediately.

For the hydraulic oil which is suddenly exploded and injected into the transition oil tank, the second detection mechanism also sends a signal feedback to the equipment control system, and the equipment stops working immediately (and sends a signal simultaneously with the first detection mechanism). When oil leaks from the joint position (phenomenon before pipe explosion) but not from the pipe explosion, the second detection mechanism sends signal feedback to the equipment control system, and the control system prompts an operator to check the hydraulic oil pipe (because hydraulic oil is in leakage phenomenon, pressure is small or basically no pressure, the first detection mechanism cannot be triggered, and the first detection mechanism does not send signals to the equipment control system).
The bottom plate of the transition oil tank is formed by connecting a horizontal plate and an inclined plate, the lower end of the inclined plate is fixedly connected with the horizontal plate, and the second detection mechanism is installed on the horizontal plate. The inclined plate can guide the hydraulic oil entering the transition oil tank to flow to the bottom of the horizontal plate at the lowest position to trigger the second detection mechanism.
