When the device is used, the lifting device 200 drives the oil cup 341 to ascend to be attached to an oil tank, the driving mechanism 0 drives the spiral cone 330 to rotate and ascend, the spiral cone 330 can rapidly puncture the oil tank, and the driving mechanism drives the spiral cone 330 to descend to enable oil in the oil tank to flow into the oil cup; when the spiral cone 330 descends, the upward flange at the opening of the oil tank is pulled back downwards through the spiral at the outer side, so that the flange of the oil tank is downward, and smooth oil discharge and thorough oil discharge are ensured.

Specifically, the main working unit 300 (see fig. 3) is mainly composed of three parts, i.e., an upper spiral cone 330, a middle driving mechanism, and a lower screw nut pair.

The spiral cone 330 is composed of an upper cone 331, a spiral body 332, a cylindrical body 333, and second end teeth 334 at the lower end, and an annular groove 335 is provided between the cylindrical body 333 and the second end teeth 334 at the lower end.

The oil cup 341 is in the shape of an open cup. An oil drain pipe 342 is connected to the lower part of one side for draining oil. The upper part of the oil cup 341 is provided with an upper sealing ring 343. The bottom of the oil cup 341 is provided with a through hole for the cylinder 333 of the spiral cone 330 to pass through (slide fit), the lower sealing ring 344 is sleeved on the cylinder 333, and the lower sealing ring 344 is fixed by the backing plate 345. The lower end of the oil cup 341 is fixedly connected with the top of the upper shell 325 through a flange.

The one-way bearing 351 is arranged outside the cylinder 333 at the lower part of the spiral cone 330. The inner ring of the one-way bearing 351 is fixedly coupled with the cylinder 333 through a key. The outer ring of the one-way bearing 351 is fixedly connected with the inner hole of the sliding bearing seat 352. A keyway is vertically provided on the outside of the sliding bearing block 352, which is in sliding engagement with a guide key 355 fixedly provided on the inside surface of the upper housing 325. The outer rings of the sliding bearing block 352 and the one-way bearing 351 can only move up and down but cannot rotate. The one-way bearing 351 allows the spiral cone 330 to rotate only counterclockwise (when viewed from above) and not in the reverse direction.

The lower end of the spiral cone 330 is provided with second end teeth 334. Second end teeth 334 at the lower end of spiral cone 330 engage first end teeth 328 provided at the upper end of spline shaft 327.

lower housings

325 and 326 by a bearing 324. The worm 322 is rotatably mounted on the joint surface of the housing through a bearing, and the worm 322 and the worm wheel 323 form a worm-gear pair.

The reduction motor 321 is fixedly installed outside the housing. The output shaft of the reduction motor 321 drives the worm 322 to rotate through the coupling.

The spline shaft 327 is vertically and movably arranged in the central hole of the worm wheel 323, and the worm wheel 323 and the spline shaft 327 form a ball spline pair.

The lower end of the spline shaft 327 is fixedly coupled to the upper end of the ball screw 312 via a coupling 314. The upper end of the spline shaft 327 is provided with first end teeth 328. First end teeth 328 at the upper end of spline shaft 327 mate with first end teeth 334 provided at the lower end of spiral cone 330. Spline shaft 327 drives spiral cone 330 counterclockwise (looking down from above) via first end tooth 328, and when spline shaft 327 is rotated in reverse, first end tooth 328 disengages from second end tooth 334.

A backing plate 345 is also provided on the top of the upper housing 325 to hold (secure) the lower seal 344.

The screw nut pair (see fig. 6) mainly comprises a ball nut 311, a ball screw 312, a support sleeve 313 and the like.

The ball nut 311 is fixedly installed in the support sleeve 313. The ball nut 311 and the ball screw 312 constitute a screw nut pair. The upper end of the ball screw 312 is fixedly coupled to the lower end of the spline shaft 327 by a coupling 314. The upper end of the support sleeve 313 is fixedly connected with the lower end of the lower shell 326 through a flange.

The small handcart 100 (see fig. 2) is composed of an axle 101, wheels 102, a vertical rod 103, a handcart handle 104 and the like. Wheels 102 are rotatably mounted at two ends of the horizontal axle 101; a vertical rod 103 is vertically and fixedly arranged in the middle of the horizontal axle 101, and a trolley handle 104 is arranged at the top end of the vertical rod 103.

The lifting device 200 (see fig. 2) is fixedly mounted on the upright 103 of the trolley 100 through a fixing bracket 105. The lifting device 200 is mainly composed of an air cylinder or a hydraulic cylinder. The lower end of the cylinder 201 is hinged with a support plate 203. The working unit 300 is fixedly installed on the top end of the piston rod 202.

When the lifting device is used, the old automobile is lifted by the lifting machine. The device is arranged under the oil tank through a small trailer, so that the equipment is in a vertical state, and the tip of the spiral cone is aligned to the lowest position (to-be-perforated oil drainage position) under the oil tank.

The lifting device 200 is controlled to make the piston rod 202 push the work machine 300 to rise, so that the cup mouth of the oil cup 341 is tightly attached to the lower surface of the oil tank (the upper sealing ring 343 is used for sealing).

Starting the speed reducing motor 321, driving the worm wheel 323 to rotate anticlockwise by the speed reducing motor 321 through the worm 322, driving the spline shaft 327 to rotate anticlockwise by the worm wheel 323, driving the ball screw 312 to rotate anticlockwise by the lower end of the spline shaft 327 through the coupler 314, and driving the spline shaft 327 and the spiral cone 330 to move upwards as the ball screw 312 moves upwards because the ball nut 311 is fixed and does not rotate; while splined shaft 327 drives spiral cone 330 counterclockwise via first end teeth 328. The spiral cone 330 breaks the tank counterclockwise upward and screws into the tank.

The reduction motor 321 is controlled to rotate reversely. The speed reducing motor 321 drives the worm wheel 323 to rotate clockwise through the worm 322, the worm wheel 323 drives the spline shaft 327 to rotate clockwise, the lower end of the spline shaft 327 drives the ball screw 312 to rotate clockwise through the coupler 314, and the ball screw 312 moves downwards due to the fact that the ball nut 311 is fixed and does not rotate, and the spline shaft 327 is pulled to move downwards. At this point, the end teeth are disengaged and the splined shaft 327 pulls the helical cone 330 downward through the coupling sleeve 353. The spiral cone 330 cannot rotate in the reverse direction because of the one-way bearing 351. The spiral cone 330 is pulled back downwards, and the upward flange at the opening of the oil tank is pulled back downwards through the spiral at the outer side, so that oil discharge is smooth. The oil in the oil tank flows into the oil cup from the opening and is discharged through the oil discharge pipe 342. After the oil is discharged, the working main machine is lowered through the lifting device 200, and the equipment is dragged out, so that the work is completed.

The device punctures the oil tank bottom plate upwards through the spiral taper rod and screws the spiral taper rod into the oil tank, and then statically pulls back the spiral taper rod to enlarge the hole, so that the flanging of the hole opening faces outwards (downwards), oil discharge is smooth, and the oil discharge is thorough.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
