Abstract

The invention discloses a hydraulic spiral taper rod drilling, pulling, and oil discharge device, which includes a lifting device and a working host; the working host includes a frame and an oil cup, and the oil cup is connected to the top of the frame; the frame is connected to the output of the lifting device The anti-reverse control device and the transmission device are connected to the frame. The anti-reverse control device is equipped with a spiral cone rod. The transmission device includes a ball screw. The top of the ball screw is connected to the bottom end of the spiral cone rod; The spiral cone has a first state and a second state. In the first state, the top of the spiral cone is located in the oil cup. In the second state, the top of the spiral cone is above the oil cup; the ball screw rises and rotates to drive the spiral The cone rod rises and rotates, and the spiral cone rod moves from the first state to the second state; the ball screw descends to drive the spiral cone rod to descend, and the spiral cone rod moves from the second state to the first state; This ensures smooth and thorough oil discharge.

Description

technical field

[0001] The invention relates to the technical field of oil tank cleaning equipment, in particular to a hydraulic spiral taper rod drilling and pulling hole oil discharge device. Background technique

[0002] With the improvement of people's living standards, the number of cars owned is increasing, but the amount of scrapped cars is also increasing year by year. In China alone, nearly ten million cars need to be scrapped every year. Before the car is scrapped, it is first necessary to discharge the remaining gasoline and other oils in the fuel tank to reuse resources and avoid polluting the environment. In the past, the fuel tank was often disassembled and poured out manually, which not only requires a lot of work, but also has low efficiency and cannot meet the requirements of a large number of dismantling. Some enterprises have introduced foreign equipment and adopted the technology of piercing the fuel tank with a sharp cone to discharge oil, but the oil d...
