A device for testing the oil level of multiple fuel tanks of an automatic drilling rig

Abstract

The invention relates to the technical field of oil level testing equipment, in particular to a device for testing the oil level of multiple fuel tanks in an automatic drilling rig, including a first fuel tank and a second fuel tank, and a connecting pipe is used between the first fuel tank and the second fuel tank conduction, the bottom end of the second fuel tank is connected with a test structure, the first fuel tank and the second fuel tank are stored and protected by a protective structure, and a pressure relief structure is provided on the protective structure; the first fuel tank and the The second fuel tank is provided with a sealing structure for controlling the sealing of the fuel tank, and the first fuel tank and the second fuel tank are provided with an exhaust structure for exhausting, and the sealing structure can drive the exhaust structure; The protective structure is equipped with a driving structure for driving the refueling barrel to move. The liquid level test effect is good, the use is stable, the oil is added stably and conveniently, the operation efficiency is high, and the effect of pressure resistance and pressure relief is good.

Description

technical field [0001] The invention relates to the technical field of oil level testing equipment, in particular to a device for testing oil levels in multiple fuel tanks of an automatic drilling rig. Background technique [0002] Automatic drilling rig products are widely used in various types of engineering construction, mining, hydropower engineering, tunnel road construction, railway anchoring and other mechanized projects. The working time of continuous operation is at least 8-10 hours. At present, the power of the engine supporting the automatic drilling rig is basically above 300-400kW. According to the calculation of the fuel consumption of the engine, the design capacity of the fuel tank needs to be more than 700-1000 cubic meters to satisfy the user. Use requirements, and when the user is actually using it on site, the volume of the fuel tank is required to be larger to facilitate the actual use of production. With the expansion of the application field of automat...

Problems solved by technology

[0003] However, the electrical system of the unit needs to display the real-time fuel position of the fuel tank, output alarm signals for high and low fuel positions, etc., to meet the intelligent control requirements of the electrical system of the unit. The resistance sensor is realized by using a linear sliding rheostat, and the resistance value is controlled by a float. As the oil volume changes, the resistance value will also change accordingly. The controller tests the fuel oil level according to the resistance value tested by the sensor. , to realize display, alarm and other functions, this method is only suitable for the measurement of the fuel volume of a fuel tank with a basic square shape, and is not suitable for the situation where two or more or even special-shaped fuel tanks are connected to store fuel, so electrical intelligence cannot be realized At the same time, most of the fuel tanks are directly fixed on the equipment, and do not have the function of pressure relief and protection. When encountering foreign objects, it is easy to cause damage to the fuel tank, and most of the top of the fuel tank is directly equipped with an end cover, and the sealing port of the end cover is small. When adding oil directly, it is easy to cause oil splashing. At the same time, the vent hole set in the oil tank is set separately. When adding oil, it needs to be opened manually. When the oil is added, it is not convenient to take out the adding barrel in time, and the operation flexibility is poor.
