The bottom platform 1 is provided with a lifting mechanism, and the upper part of the lifting mechanism is provided with a telescopic suspension arm telescopic mechanism. The lifting mechanism comprises a first hydraulic oil cylinder 8 arranged on the bottom platform 1, a telescopic lifting mechanism telescopic part 9 is arranged in the first hydraulic oil cylinder 8, a horizontal fixing part 16 is arranged at the tail end of the lifting mechanism telescopic part 9, a second hydraulic oil cylinder 14 of the suspension arm telescopic mechanism is arranged on the horizontal fixing part 16, a telescopic suspension arm telescopic part 13 is arranged in the second hydraulic oil cylinder 14, and a suspension rope 11 is arranged on the suspension arm telescopic part 13; the lifting rope 11 is connected with a lifting ring 10 for lifting the battery box. The horizontal fixing piece 16 is connected with the middle part of a horizontally arranged suspension arm fixing piece 15, and two ends of the suspension arm fixing piece 15 are respectively connected with the second hydraulic oil cylinder 14. A plurality of lifting rope fixing points 12 which are uniformly distributed at intervals are arranged on the lifting arm telescopic piece 13, and the installation requirements of battery box bodies with different specifications can be met by changing the positions of the lifting ropes 11.

The lifting mechanism and the suspension arm telescopic mechanism are hydraulic jacks, and the lifting mechanism comprises a first pedal 2 which is arranged at the bottom of the bottom platform 1 and used for lifting the lifting mechanism and a first rocker 18 used for lowering the lifting mechanism; the suspension arm telescopic mechanism comprises a second pedal 3 which is arranged on the bottom platform 1 and enables the suspension arm telescopic mechanism to extend and a second rocker 19 which enables the suspension arm telescopic mechanism to shorten; the positions of the first rocker 18 and the second rocker 19 are higher than the positions of the first pedal 2 and the second pedal 3. The position of the first rocker 18 and the second rocker 19 facilitates manual operation. And the first pedal 2 and the second pedal 3 are positioned lower for foot operation. The principle of the hydraulic jack is adopted, the manual operation can be realized, but the hydraulic jack is different from a common jack. The common jack comprises a pedal for extending the jack, a rocker for contracting the jack, a hydraulic oil cylinder, a telescopic piece in the hydraulic oil cylinder, a hydraulic oil pump, a piston in the hydraulic oil cylinder, an oil tank, a pipeline and other accessories. The lifting mechanism and the suspension arm telescopic mechanism are equivalent to the telescopic ends of two jacks which are connected in series in the vertical direction and the horizontal direction, but the pedal, the rocker and the oil tank are arranged on the bottom platform. The first pedal 2 and the second pedal 3 can be operated by foot to lead the lifting mechanism to lift and the suspension arm telescopic mechanism to extend; the first rocker 18 and the second rocker 19 are operated to lower the lifting mechanism and retract the boom extension mechanism, thereby adjusting the position of the hoist ring 10. The bottom platform 1 is also provided with a first oil tank 5 and a first hydraulic oil pump 20 belonging to the lifting mechanism, a second oil tank 17 and a second hydraulic oil pump 21 belonging to the boom extension mechanism, and a mechanism of connected oil pipes and internal valve bodies. The concrete connection mode of the components is the same as the principle of the hydraulic jack. The lifting mechanism is taken as an example for explanation. The lifting mechanism comprises a first pedal 2, a first hydraulic oil pump 20, a piston 31 in the first hydraulic oil pump 20, a connecting rod 33 for connecting the first pedal 2 and the piston 31, a first oil tank 5, a first hydraulic oil cylinder 8, a hydraulic oil cylinder piston 28 in the first hydraulic oil cylinder 8, a lifting mechanism telescopic piece 9, an oil pipe A37, an oil pipe B42, an oil pipe C43, a check valve A (25) in the oil pipe B42, a check valve B (26) in the oil pipe A37, an oil drain valve 27 in the oil pipe C43 and a connecting piece 36 for connecting the first rocker 18 and the oil drain valve 27.

The lifting principle of the lifting mechanism is explained as follows: when the first pedal 2 is returned upward, the connecting rod 33 drives the piston 31 to move upward, and the working volume of the first hydraulic oil pump 20 increases. At this time, since the oil discharge check valve a25 and the oil discharge valve 27 close their respective oil passages, the internal volume of the first hydraulic oil pump 20 increases to form a partial vacuum, and the hydraulic oil in the hydraulic first oil tank 5 enters the first hydraulic oil pump 20 through the check valve B26, thereby completing one oil suction operation.

When the first pedal 2 is stepped downward, the piston 31 moves downward, and the seal displacement volume in the first hydraulic oil pump 20 decreases. At this time, since the oil discharge check valve B26 and the oil discharge valve 27 close their respective oil passages, the hydraulic oil in the first hydraulic oil pump 20 enters the first hydraulic oil cylinder 8 through the check valve a25, and the hydraulic oil in the first hydraulic oil cylinder 8 pushes the hydraulic oil cylinder piston to move upward, so that the lifting mechanism telescopic member 9 extends upward. The first pedal 2 is repeatedly returned and stepped downwards, so that the telescopic part 9 of the lifting mechanism can continuously rise, and the height is continuously increased.

The first rocker 18 can be shaken to open the oil drain valve 27 through the driving of the connecting piece 36, the piston of the hydraulic oil cylinder moves downwards under the action of the self gravity and the gravity of the telescopic piece 9 of the lifting mechanism, and the hydraulic oil 41 flows back into the first oil tank 5 through the oil drain valve 27. The oil drain valve 27 can be opened or closed at any time by the first rocker 18, thereby adjusting the height of the hydraulic lifting mechanism.

The principle and structure of the boom extension mechanism are similar and will not be described in detail. The only difference is that when the boom is retracted, the power for the hydraulic oil in the hydraulic cylinders of the boom to flow back into its corresponding second oil tank 17 comes not from the effect of the gravity of the boom extension 13 but from the force generated by the operator pulling back the boom extension 13 by means of the boom cable 11.

The bottom platform 1 is provided with a vertical fixed rod, and the fixed rod is provided with a handrail 7. The handrail 7 has 2 semicircular structures, humanized design, and the handrail is conveniently held by the human hand and the operation comfort level is improved.

The roller connecting piece 44 is provided with a roller shaft 46, and the roller 45 is rotatably arranged on the roller shaft 46. The self-locking device 48 is connected with the roller connecting piece 44 through a pin 47. The end of the limiting device 50 is provided with a mechanism such as a hook, the limiting device 50 is rotatably arranged on the semicircular ring 49, the self-locking device 48 is provided with a snap ring 51 which can be connected with the hook of the limiting device 50, and the snap ring 51 can be in a semicircular ring shape or other shapes. When the limiting device 50 is lifted and the roller self-locking device 48 is stepped, the roller 45 is clamped by the self-locking device 48, the clamping hook of the limiting device 50 is fixed on the clamping ring 51, the roller 45 is clamped by the self-locking device 48, large friction force is generated to enable the wheel not to rotate, the self-locking purpose is achieved, and at the moment, the battery box installation mechanism cannot move. When the self-locking is unlocked, the hook of the limiting device 50 is connected with the tail end of the self-locking device, and the self-locking device 48 is in a state of upwards leaving the roller 45 at the moment. In this embodiment, the end of the snap ring 51 and the self-locking device 48 are two connection points. Other connection points may of course be provided.
