A switcher is provided on the vehicle body 1, and the actuator of the switcher controls the connection between the X-direction moving rollers 4 and the Y-direction moving rollers 5.

[0025] In use, the trolley body 1 is controlled to move on the support 2 to adjust the position of the trolley body 1 (i.e. to move the trolley body 1 directly above the storage basket 3 to be lifted), since the X-direction moving rollers 4 and the Y-direction moving rollers 5 are arranged on the trolley body 1, when it is necessary to adjust the position of the trolley body 1 in the X-direction on the support 2, the switcher is switched to make the X-direction moving rollers 4 work and the Y-direction moving rollers 5 retract, so that the trolley body 1 moves along the X-direction cross beams 6 under the action of the X-direction moving rollers 4 to change the position of the trolley body 1 in the X-direction on the support 2; conversely, when it is necessary to adjust the position of the trolley body 1 in the Y-direction on the support 2, the switcher is switched to make the Y-direction moving rollers 5 work and the X-direction moving rollers 4 retract, so that the trolley body 1 moves along the Y-direction cross beams 7 under the action of the Y-direction moving rollers 5 to change the position of the trolley in the Y-direction on the support 2, and then the trolley body 1 is moved to the preset position, after that, the first driving mechanism is controlled to lower the lifting rope 8, the lifting rope 8 is lowered to make the clamping hook hook the hanging opening 9 on the storage basket 3, so as to lift the storage basket 3, since the distance from the top to the bottom of the storage basket 3 is less than the distance between the lower surface of the lifting frame 17 and the lower surface of the trolley body 1, after the first driving mechanism retracts the lifting rope 8, the storage basket 3 is moved to the position directly below the lifting frame 17, the storage basket 3 will not contact the X-direction cross beams 6 and the Y-direction cross beams 7, so as not to affect the movement of the trolley body 1 on the top of the support 2 due to lifting the storage basket 3, then the trolley body 1 is controlled to move to the position to be moved, and then the first driving mechanism is controlled to lower the lifting rope 8, and then the clamping hook is taken out of the hanging opening 9. In this way, the storage basket 3 is moved to the target position by the trolley body 1.

[0026] As a preferred mode, the top of the support 2 is provided with a plurality of X-direction cross beams 6 and Y-direction cross beams 7, the X-direction cross beams 6 and the Y-direction cross beams 7 are located in the same horizontal plane, any two X-direction cross beams 6 are parallel to each other, any two Y-direction cross beams 7 are parallel to each other, any one X-direction cross beam 6 and any one Y-direction cross beam 7 are perpendicular to each other and intersect, the upper surface of the X-direction cross beam 6 is provided with a wheel groove 10 along the length direction of the X-direction cross beam 6, the X-direction moving roller 4 can roll in the wheel groove 10 on the X-direction cross beam 6, the upper surface of the Y-direction cross beam 7 is provided with a wheel groove 10 along the length direction of the Y-direction cross beam 7, the Y-direction moving roller 5 can roll in the wheel groove 10 on the Y-direction cross beam 7. After such arrangement, the top of the support 2 forms a plurality of grids, after the trolley body 1 moves, the lifting rope 8 is lowered at the corresponding grid (a pattern formed by two adjacent X-direction cross beams 6 and two adjacent Y-direction cross beams 7) to achieve the purpose of lifting the storage basket 3.

[0027] As a preferred mode, the switching device is a lifting device 11, the bottom of the trolley body 1 is provided with the X-direction moving roller 4, and the Y-direction moving roller 5 is fixedly arranged on the trolley body 1 through the lifting device 11. After the lifting device 11 is arranged, when the lifting device 11 is lowered, the Y-direction moving roller 5 can be ensured to be in contact with the Y-direction beam 7, and at the same time, the X-direction moving roller 4 is suspended, that is, the X-direction moving roller 4 is not in contact with the X-direction beam 6; when the lifting device 11 is raised, the Y-direction moving roller 5 is suspended, that is, the Y-direction moving roller 5 is not in contact with the Y-direction beam 7, and at the same time, the X-direction moving roller 4 is in contact with the X-direction beam 6.

The purpose of arranging four hanging ropes 8 is to make the pulling force on the storage basket 3 uniform during lifting the storage basket 3. The heavy plate 14 has two purposes. One is to control the relative position relationship between the four hanging ropes 8, so as to prevent the clamping hooks on the four hanging ropes 8 from swinging (out of synchronization). The other is to make the gravity of the heavy plate 14 and the edge of the hanging opening 9 on the storage basket 3 press the pressure trigger together when the clamping hook contacts the hanging opening 9, so that the clamping hook can hook the hanging opening 9.

[0030] As a preferred mode, the four clamping hooks are uniformly distributed around the geometric center of the heavy plate 14.

[0033] The vertical part of the L-shaped second hook body 13 is fixedly connected to the lower surface of the heavy plate 14 away from one end of the horizontal part, the vertical part of the L-shaped second hook body 13 is perpendicular to the lower surface of the heavy plate 14, the lower surface of one end of the horizontal part of the L-shaped second hook body 13 away from the vertical part is provided with a slope 15, the distance from one end of the free end of the horizontal part of the L-shaped second hook body 13 to the upper surface of the horizontal part of the L-shaped second hook body 13 is less than the distance from the other end of the free end of the horizontal part of the L-shaped second hook body 13 to the upper surface of the horizontal part of the L-shaped second hook body 13.

[0034] The vertical part of the L-shaped first hook body 12 and the vertical part of the L-shaped second hook body 13 are provided with a preset gap, the transverse part of the L-shaped first hook body 12 is located on the side of the vertical part of the L-shaped first hook body 12 away from the second hook body 13, the transverse part of the L-shaped second hook body 13 is located on the side of the vertical part of the L-shaped second hook body 13 away from the first hook body 12, and the vertical part of the L-shaped first hook body 12 and the vertical part of the L-shaped second hook body 13 are both elastic;

[0035] A horizontal plate 16 parallel to the bottom wall of the storage basket 3 is arranged on the side wall of the storage basket 3 close to the opening, the hanging opening 9 is arranged on the horizontal plate 16, the length of the hanging opening 9 is greater than the distance between the end of the inclined surface 15 on the first hook body 12 facing the second hook body 13 and the end of the inclined surface on the second hook body 13 facing the first hook body 12, and the length of the hanging opening 9 is less than the distance between the end of the inclined surface 15 on the first hook body 12 away from the second hook body 13 and the end of the inclined surface 15 on the second hook body 13 away from the first hook body 12.

[0036] After the setting, when the clamping hook descends with the heavy plate 14, the slope 15 of the lower end of the clamping hook first contacts the edge of the hanging opening 9. With the first driving mechanism (the first driving mechanism can adopt the way of four servo motors, each servo motor is provided with a belt pulley on the output shaft, and the upper end of the lifting rope 8 is fixedly connected with the circumferential surface of the belt pulley. After the setting, if the servo motor rotates forward, the lifting rope 8 is wound on the belt pulley to realize the function of lifting the storage basket 3, and when the servo motor reverses, the lifting rope 8 wound on the belt pulley is released, thereby achieving the function of putting down the storage basket 3), the lifting rope 8 is continuously released, the pressure of the heavy plate 14 on the clamping hook is continuously increased, thereby the first hook body 12 and the second hook body 13 are continuously inserted into the hanging opening 9. During the insertion, due to the setting of the slope 15, the edge of the hanging opening 9 further extrudes the first hook body 12 and the second hook body 13 towards each other, so that the horizontal part of the L-shaped first hook body 12 and the horizontal part of the second hook body 13 are both inserted into the hanging opening 9 (that is, they penetrate the hanging opening 9 and are inserted into the lower surface of the horizontal plate 16), so that the vertical part of the L-shaped first hook body 12 and the vertical part of the L-shaped second hook body 13 both have elasticity. After the first driving mechanism retracts the lifting rope 8, the gravity is pulled by the lifting rope 8 and no longer exerts pressure on the first hook body 12 and the second hook body 13. At this time, the horizontal part of the first hook body 12 and the horizontal part of the second hook body 13 restore the original shape, so that the horizontal part of the first hook body 12 and the horizontal part of the second hook body 13 are both located below the horizontal plate 16, and the horizontal plate 16 is supported by the horizontal part of the first hook body 12 and the horizontal part of the second hook body 13 during the lifting of the first hook body 12 and the second hook body 13 by the lifting rope 8, thereby lifting the horizontal plate 16 and the storage basket 3 together (because the horizontal plate 16 is fixedly arranged on the storage basket 3).
