Open type turnover oil tank and working method thereof

Abstract

The invention discloses an open type turnover oil tank and a working method thereof. The open type turnover oil tank comprises a tank body, an oil return opening is formed in a top plate of the tank body, and an oil suction opening is formed in a bottom plate of the tank body; a first air filter and a second air filter are further arranged on the top plate, the first air filter is communicated with air above oil in the box body through a normally-open electromagnetic ball valve, a first normally-closed manual ball valve is connected to the normally-open electromagnetic ball valve in parallel, and the second air filter is communicated with air above the oil in the box body through a normally-closed electromagnetic ball valve. A second normally closed manual ball valve is connected to the normally closed electromagnetic ball valve in parallel; the oil tank further comprises a detection assembly which comprises a first liquid level sensor, a second liquid level sensor and a third liquid level sensor, wherein the first liquid level sensor and the second liquid level sensor are arranged on one side plate. According to the open type turnover oil tank, different vent holes of the oil tank are controlled through the two electromagnetic ball valves according to the turnover posture of the self-lifting crane, so that the vent holes are always kept in the oil-free area of the oil tank in the working process, and the open type turnover oil tank can be used in the turnover process of the self-lifting crane.

Description

technical field [0001] The invention relates to the field of self-elevating cranes, in particular to an open overturned oil tank and a working method thereof. Background technique [0002] Currently, in the maintenance process of wind power generators, it is necessary to use a crane to hoist the maintenance equipment from the tower to the tower, so self-hoisting cranes appear. At present, most of my country's crane field adopts open fuel tanks, the liquid level in the tank body of the open fuel tanks communicates with the atmosphere, and an air filter is installed on the fuel tank cover. When the self-hoisting crane is lifted from the tower to the tower, the oil tank of the crane will undergo multiple flips. During the flipping process of the traditional open fuel tank, the position of the vent hole of the fuel tank will not change, and oil leakage will occur. As a result, the open fuel tank cannot be used when it is turned over. [0003] Therefore, the open fuel tank in t...

Problems solved by technology

When the self-hoisting crane is lifted from the tower to the tower, the oil tank of the crane will undergo multiple flips. During the flipping process of the traditional open fuel tank, the position of the vent hole of the fuel tank will not change, and oil leakage will occur. Causes open fuel tanks to be unusable when flipped over
