Problems solved by technology

At present, the general method of cooling hydraulic oil is to install a plate-fin cooler outside the oil tank, and exchange heat through convection between oil and water inside it. Due to the limited volume, the cooling water flow is also limited, so the cooling speed cannot keep up, resulting in the oil returning to the oil tank after cooling still has a relatively high temperature

Embodiment

[0017] Example: The invention has a built-in water cooling and dust removal device for the oil tank of a roadheader, such as figure 1 , figure 2 As shown, it includes an oil tank 1, a serpentine copper tube cooler 2, two high-pressure articulated joints 3, a ball valve 4, a hose 8; 9; 10, a water pressure safety valve 5, a water spray bracket 6 and a scraper conveyor 7. The serpentine copper tube cooler 2 is built in the oil tank 1. The serpentine copper tube cooler 2 cools the hydraulic oil through heat exchange between the flowing cooling water and the hydraulic oil in the oil tank 1. The serpentine copper pipe in the spool is arranged in the oil tank 1, so the contact area with the hydraulic oil is large, the cooling water can fully exchange heat with the hydraulic oil, and the cooling efficiency is higher; the high-pressure articulated joint 3 is installed in the The serpentine copper tube cooler 2 extends out of the nozzle of the oil tank 1, and the pipeline direction of t...

Abstract

The invention discloses a built-in water-cooling and dust-removing device for a fuel tank of a road-header, wherein a snakelike copper tube cooler is internally installed in the fuel tank to cool hydraulic oil; a water inlet of the snakelike copper tube cooler is connected with a water pressure safety valve through a high-pressure hinge joint and a rubber tube to adjust the water inlet pressure; a water outlet of the snakelike copper tube cooler is connected with a first connector of a ball valve through another high-pressure hinge joint and another rubber tube; a second connector of the ball valve is connected with a water spray bracket through another rubber tube; and water orifice of the water spray bracket sprays water to the tail part of a scraper conveyor. According to the built-in water-cooling and dust-removing device for the fuel tank of the road-header, the snakelike copper tube cooler is internally installed in the fuel tank, so that the hydraulic oil is directly and efficiently cooled, defects of the cooling method of a traditional external plate-fin type cooler are effectively overcame, and the cooling is rapid; and the used cooling water is used for removing dust when the road-header is in the cutting process, and the cooling water is fed into a roof bolter when the road-header is free from the cutting process, so that the hydraulic oil can be continuously cooled during two time periods of cutting work and cutting-free work, and the cooling water is also recycled effectively.

Description

Technical field [0001] The invention relates to a roadheader, in particular to a built-in water cooling and dust removal device of an oil tank of the roadheader. Background technique [0002] The roadheader is a machine used to excavate straight underground roadways. The oil temperature rises quickly during cutting and tunneling, which can easily cause the seal to fail. Lowering the oil temperature is a key technical means for the roadheader to ensure high production. It can be seen that the fuel tank is built-in Water cooling and dust removal system is one of the decisive factors to ensure the high efficiency of the roadheader. At present, the general method of cooling hydraulic oil is to install a plate-fin cooler outside the oil tank, and exchange heat inside it through oil and water convection. However, the space for arranging this cooler on the roadheader is limited, making the number of coolers selected And the volume is limited, the cooling water flow is also limited, so ...
