TECHNICAL FIELD

[0001] The utility model relates to fireproof device technical field, concretely relates to a fireproof device for rig. BACKGROUND

[0002] The diesel engine with turbocharger and intercooler is generally used as the power source in the working process of the rig to improve the power density, but a region with a higher temperature than the naturally aspirated engine is generated in the working process of the diesel engine, that is, the turbocharger exhaust end and the exhaust pipe communicated with the turbocharger exhaust end, the temperature of which can reach 495 degrees in normal working, and the high-temperature area can be obviously seen in bright orange at night, if the right rear high-pressure oil pipe bursts, the diesel and hydraulic oil will splash to the high-temperature area and catch fire instantaneously, which is highly dangerous, so the engine position of the rig needs to be protected to avoid fire.

[0003] Currently, there are two common methods, one of which is to set a side baffle on the turbocharger and the turbocharger exhaust end for protection, which cannot protect the position of the exhaust pipe, and the splashed high-pressure oil will still cause a fire if it flows to the turbocharger exhaust end of the high-temperature area through the vertical exhaust pipe, and the other is to set a vertical baffle between the high-pressure oil pipe and the turbocharger, and set a heat insulation blanket on the exhaust pipe and the turbocharger exhaust end, which can play a certain heat insulation role to avoid the high-pressure oil flowing to the turbocharger exhaust end along the exhaust pipe, but this method will affect the heat dissipation of the part, increase the oil temperature for lubricating the exhaust end turbine, and increase the probability of damage to the turbocharger rotor, and the heat insulation blanket has a certain thickness, which is inconvenient to install. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a fireproof device for a rig, which can avoid fire caused by high-pressure oil splashing to the high-temperature area of the engine after the high-pressure oil pipe bursts and improve the safety of the equipment.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is as follows.

[0006] A fireproof device for a rig, comprising a protective cover for protecting the turbocharger and the turbocharger exhaust end and a heat insulation assembly arranged on the exhaust pipe and the turbocharger exhaust end, the turbocharger exhaust end is communicated with the turbocharger, and the turbocharger exhaust end is communicated with the exhaust pipe through a connecting elbow.

[0016] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0017] A fireproof device for a drilling machine, as shown in Figs. 1 to 3 The present application comprises a protective cover 1 for protecting the turbocharger 5 and the turbocharger exhaust end 6 and a heat insulation assembly arranged on the exhaust pipe 4 and the turbocharger exhaust end 6. The turbocharger exhaust end 6 is in communication with the turbocharger 5, and the turbocharger exhaust end 6 is in communication with the exhaust pipe 4 through the connecting elbow 7.

[0018] The protective cover 1 is in a shape of a Chinese character "fang", covers and protects the turbocharger 5 and the bottom, top and side of the turbocharger exhaust end 6, and can prevent the right rear high-pressure oil pipe from splashing on the turbocharger 5 and the turbocharger exhaust end 6 to cause fire.
