Referring to fig. 1, 2, 3, 4 and 5, the hand-push type tank car comprises a car frame 1, a tilt power-assisted mechanism 6 and a horizontal power-assisted mechanism.

The liquid storage tank is provided with a push handle 21. The armrest is provided with a slope power assisting mechanism part power assisting electromagnet opening switch 61 and a horizontal power assisting mechanism part power assisting electromagnet opening switch 71, and both the slope power assisting mechanism part power assisting electromagnet opening switch 61 and the horizontal power assisting mechanism part power assisting electromagnet opening switch 71 are push switches. The lower end of the liquid storage tank is provided with a bracket 22 and a discharge steel pipe 23. The discharge steel pipe is provided with a discharge valve 231. The inlet of the discharge steel pipe is positioned at the lowest point of the inner space of the liquid storage tank when the liquid storage tank is in an inclined state. When in use, the invention is pushed by a push to move the invention to a destination. The rotation of the liquid storage tank is realized by taking the sucker disk as a shaft.

The rotating disc is provided with a support column 13. The carriage is hinged to the support column by a horizontally extending hinge shaft 14. The rotating disc is provided with a horizontal position limiting column 17 and an inclined position limiting column 16.

The inclined position limiting column comprises an inclined position limiting column lower section 162 with the lower end fixedly connected on the rotating disc and an inclined position limiting column upper section 163 with the lower end penetrating into the upper end of the inclined position limiting column lower section.

The upper end of the upper section of the inclined position limiting column is wrapped with an inclined boosting mechanism part rubber cap 62. An inclined boosting mechanism part liquid storage cavity 63 is formed between the inclined boosting mechanism part rubber cap 62 and the upper section of the inclined position limiting column. The liquid storage cavity of the inclined power-assisted mechanism part is internally provided with an inclined power-assisted mechanism part pressure switch 67. The bracket part first ferromagnet is arranged on the bracket and is used for pressing the rubber cap of the inclination assisting mechanism part. The distance between the liquid storage cavity of the inclined power-assisted mechanism part and the first ferromagnetic body of the bracket part is 2.2-2.9 mm.

The process of inclining the liquid storage tank comprises the following steps: after the switch 61 is turned on by the power-assisted electromagnet of the tilt power-assisted mechanism part, the bracket is turned towards the tilt power-assisted mechanism, and when the switch is turned on by the power-assisted electromagnet of the tilt power-assisted mechanism part, the power-assisted electromagnet of the tilt power-assisted mechanism part cannot be conducted with a power supply, namely, the power is not supplied, so that magnetic force is generated. When the bracket rotates to the state that the first bracket part ferromagnetic body presses the liquid storage cavity of the inclination power assisting mechanism part, the pressure in the liquid storage cavity of the inclination power assisting mechanism part is increased, the pressure increase is detected by the pressure switch of the inclination power assisting mechanism part, at the moment, the power assisting electromagnet of the inclination power assisting mechanism part is communicated with the power supply to generate electricity to generate magnetic force (namely, the power assisting electromagnet of the inclination power assisting mechanism part is started), the magnetic force generates attractive force on the ferromagnetic body of the inclination power assisting mechanism part and the first bracket part ferromagnetic body, the attractive force generates force for driving the upper section of the inclination power assisting mechanism part to be inserted into the lower section of the inclination limiting column, and the bracket rotates by taking the horizontal hinge shaft as a shaft to generate moment rotating towards the inclination power assisting mechanism, so that the effect of generating inclination. When the bracket rotates to a required inclination angle, the upper section of the inclined position limiting column presses the power-assisted electromagnet closing switch of the inclined power-assisted mechanism part, so that the power-assisted electromagnet of the inclined power-assisted mechanism part is disconnected with a power supply without generating magnetic force, and the bracket is supported on the inclined position limiting column and is kept in an inclined state only through the gravity of the liquid storage tank. If the attraction of the power-assisted electromagnet is designed to drive the bracket and the object on the bracket to rotate, the bracket can be inclined only by rotating a tiny angle until the rubber cap of the inclined power-assisted mechanism part is squeezed, so that the rotation is labor-saving, and false operation can not be generated.

The horizontal position limiting column 17 comprises a horizontal position limiting column lower section 172 with the lower end fixedly connected on the rotating disc and a horizontal position limiting column upper section 173 with the lower end penetrating in the upper end of the horizontal position limiting column lower section. The horizontal power-assisted mechanism comprises a horizontal power-assisted mechanism part power-assisted electromagnet opening switch 71, a horizontal power-assisted mechanism part upper section reset spring 79 for driving the upper section of the horizontal position limiting column to extend out of the lower section of the horizontal position limiting column, a horizontal power-assisted mechanism part power-assisted electromagnet 74 arranged in the upper section of the horizontal position limiting column, a bracket part second ferromagnetic body 78, a horizontal power-assisted mechanism part ferromagnetic body 75 arranged in the horizontal power-assisted mechanism and a horizontal power-assisted mechanism part power-assisted electromagnet closing switch 76. The upper end of the upper section of the horizontal position limiting column is wrapped with a horizontal boosting mechanism part rubber cap 72. A liquid storage cavity 73 of the horizontal boosting mechanism part is formed between the rubber cap 72 of the horizontal boosting mechanism part and the upper section of the horizontal position limiting column. A pressure switch 77 of the horizontal power-assisted mechanism part is arranged in the liquid storage cavity of the horizontal power-assisted mechanism part. The bracket part second ferromagnet is arranged on the bracket and is used for pressing the horizontal boosting mechanism part rubber cap. The distance between the liquid storage cavity of the horizontal boosting mechanism part and the second ferromagnet of the bracket part is 2.2-2.9 mm.

The process of rotating the liquid storage tank from the inclined state to the horizontal state comprises the following steps: after the horizontal assisting mechanism part assisting electromagnet starting switch 71 is pressed, the bracket is rotated towards the horizontal assisting mechanism, and when the horizontal assisting mechanism part assisting electromagnet starting switch is only pressed, the horizontal assisting mechanism part assisting electromagnet cannot be conducted with a power supply, namely, the power is not supplied, so that magnetic force is generated. When the bracket rotates to the liquid storage cavity of the bracket part, the second ferromagnetic body of the bracket part presses the liquid storage cavity of the horizontal power-assisted mechanism part, the pressure in the liquid storage cavity of the horizontal power-assisted mechanism part is promoted to rise, the rise of the pressure is detected by a pressure switch of the horizontal power-assisted mechanism part, at the moment, the power-assisted electromagnet of the horizontal power-assisted mechanism part is communicated with a power supply to generate electric force (namely, the power-assisted electromagnet of the horizontal power-assisted mechanism part is started), the magnetic force generates attractive force on the ferromagnetic body of the horizontal power-assisted mechanism part and the second ferromagnetic body of the bracket part, the attractive force generates force for driving the upper section of the horizontal power-assisted mechanism part to be inserted into the lower section of the horizontal power-assisted mechanism part, and the bracket rotates by taking the. When the bracket rotates to the horizontal position, the upper section of the horizontal position limiting column presses the power-assisted electromagnet closing switch of the horizontal power-assisted mechanism part, so that the power-assisted electromagnet of the horizontal power-assisted mechanism part is disconnected with a power supply without generating magnetic force, and the bracket is supported on the horizontal position limiting column and is kept in a horizontal state only through the gravity of the liquid storage tank. When the liquid storage tank is restored to the horizontal position, namely the horizontal state, the horizontal position limiting column is contracted to a position with the length longer than the shortest position. When the horizontal power-assisted mechanism is in a free state, namely the return spring is extended to be pressed by the weight of the upper section of the horizontal position limiting column, the distance between the horizontal power-assisted mechanism and the second power-assisted electromagnet of the bracket part is 2-3 mm. If the attraction of the power-assisted electromagnet is designed to drive the bracket and the object thereon to rotate, the bracket only needs to rotate a tiny angle to the horizontal power-assisted mechanism part to be squeezed when the bracket is horizontal, so that the rotation is labor-saving and no misoperation occurs, if the horizontal power-assisted mechanism part power-assisted electromagnet is controlled by only depending on the two of an opening switch of the horizontal power-assisted mechanism part power-assisted electromagnet or a pressure switch of the horizontal power-assisted mechanism part, the misoperation is easy to occur, and the existing control method for the action part is controlled by only one person.

When the liquid storage pot inclines, the upper section of the horizontal position limiting column upwards stretches out and resets under the action of the upper section return spring of the horizontal power-assisted mechanism part, so that the pressing action on the closing switch of the horizontal power-assisted mechanism part is lost, and the power-assisted electromagnet of the horizontal power-assisted mechanism part can be started. When the bracket recovers the level, the upper section of the inclined position limiting column extends upwards to reset under the action of the reset spring of the upper section of the inclined power-assisted mechanism part, so that the pressing action on the closing switch of the inclined power-assisted mechanism part is lost, and the power-assisted electromagnet of the inclined power-assisted mechanism part can be started.

The rotating disk is provided with a plurality of positioning holes 15 distributed along the circumferential direction of the rotating disk. In the embodiment, the number of the rotary disc is 4, and the rotary disc is uniformly distributed along the circumferential direction of the rotary disc. The bracket is provided with a positioning pin 24. When the positioning pin is aligned with the positioning hole, the positioning pin penetrates through the positioning hole under the action of the self weight of the positioning pin. Two force limiters 3 distributed along the circumferential direction of the rotating disc are arranged in the positioning hole. The force limiter comprises a lifting guide groove 31 extending from the hole wall of the positioning hole to the upper end face of the rotating disc, a sliding hole 32 arranged on the bottom wall of the lifting guide groove and extending along the circumferential direction of the rotating disc, a positioning stop 33 penetrating the sliding hole and a force limiting spring 34 positioned in the sliding hole and driving the positioning stop to extend out of the limiting hole. The lift guide groove is a spiral groove centered on the axis of the rotating disk. When the positioning pin is inserted into the positioning hole during use, the positioning stop block abuts against the column positioning pin, so that the rotating disc cannot rotate freely. When the rotating disc needs to be rotated to realize the rotation of the liquid storage barrel, the force which can overcome the force of the force limiting spring to drive the positioning stop block to extend out is manually applied to rotate the liquid storage barrel, so that the positioning pin can push the positioning stop block into the sliding hole and pull out the positioning hole under the guiding action of the lifting guide groove.
