As shown in fig. 5, when the second basket 20 reciprocates along the second direction X, various arrangements can be formed with the first basket 10, specifically as follows:

in the first arrangement, when the second baskets 20 at the two ends of the first basket 10 are symmetrical about the first basket 10, the first basket 10 and the second basket 20 jointly form an I-shaped structure, and the second baskets 20 can be moved to be symmetrically arranged at the two ends of the first basket 10 during transportation, so that good stability of the whole structure is ensured.

In a second arrangement, when the second basket 20 at the first end of the first basket 10 moves in the positive direction of the second direction X, the second basket 20 at the second end of the first basket 10 moves in the negative direction of the second direction X, so that the first basket 10 and the second basket 20 form an approximate "Z" structure to adaptively repair the blades at different positions.

In a third arrangement, when the second baskets 20 at the two ends of the first basket 10 move in the same direction in the second direction X, the first basket 10 and the second basket 20 form a structure similar to a "C" shape, so as to form a common blade maintenance platform for maintaining the blades.

The embodiment of the utility model provides a through adjusting the position of the second hanging flower basket 20 that is located first hanging flower basket 10 both ends to adapt to different in service behavior, make things convenient for the whole transportation of hanging flower basket subassembly and use.

Example 2:

as an embodiment of the present invention, on the basis of the above embodiment 1, a partial alternative to the above embodiment 1 is provided.

In this embodiment, the guiding element 30 may be a guiding rod (not shown in the figure), and the guiding rod may be disposed parallel to the side surface of the second bearing platform 21 along the length direction of the second bearing platform 21 and connected to the two ends of the second bearing platform 21 through flanges.

The engaging member 40 may be a collar (not shown) correspondingly fitted on the outer surface of the guiding rod, and the collar may be fixedly mounted on the first bearing platform 11 or the first guard rail 12.

When the second basket 20 needs to move along the second direction X at two ends of the first basket 10, a force is applied to the second basket 20 to make the guide rods and the lantern rings slide in a matching manner, so that the second basket 20 moves to a required maintenance position along the extending direction of the guide rods, and a worker enters the second basket 20 to perform comprehensive maintenance or repair on the blades.

Of course, the guide rods may also be disposed parallel to the end surface of the first carrying platform 11 along the width direction of the first carrying platform 11, and connected to both sides of the first carrying platform 11 through flanges. The collar is fixed on the second bearing platform 21 or the second guard rail 22 corresponding to the installation position of the guide rod.

Example 3:

as an embodiment of the present invention, on the basis of the above embodiment 1, a partial alternative to the above embodiment 1 is provided.

The guide member 30 may include a rail body provided with a guide groove along an extending direction thereof, which may also be understood as a length direction or a guide direction of the rail, and a rack (not shown in the drawings). The rack can be arranged on one side of the outer part of the guide rail body, and can also be arranged on one side of the notch of the guide groove.

The engaging member 40 includes a pulley holder 41, and a guide pulley 42 and a gear (not shown) provided on the pulley holder 41, the guide pulley 42 can be engaged with the rail body for guiding, the gear can be engaged with the rack for driving the rail body to move, i.e., the gear can be in transmission connection with an output shaft of a driving motor (not shown), and the driving motor can be installed in the first basket 10.

When second hanging flower basket 20 is required to move along second direction X at the both ends of first hanging flower basket 10, can be through starting driving motor, make driving motor work drive gear revolve, gear and rack toothing to make guide rail body and guide pulley 42 cooperation slide, so that second hanging flower basket 20 reaches required maintenance position along the extending direction automatic movement of guide body, the staff gets into the second hanging flower basket and overhauls or maintains the blade comprehensively, high durability and convenient operation, use labour saving and time saving more.

It can be understood that the guide rail 31 provided in this embodiment has both driving and guiding functions, and can replace the manual pushing of the second hanging basket 20 to move, so that the operation is convenient, and the time and labor are saved.

Furthermore, the rack can be a roller rack, and the roller rack is suitable for being matched with the roller and used for controlling the guide rail body to move.

The roller rack is specifically a zero back clearance roller rack, 2-3 positions of teeth (rolling pins) of the zero back clearance roller rack are in contact with the rack, and no back clearance occurs in the positive and negative directions. Because no back clearance is generated between the roller and the roller rack in the driving process, high-speed operation can be realized, the reciprocating positioning precision is high, and the roller slides on the roller rack, so that the defects of low precision, high noise and larger dust generation in the process of long-distance driving transmission by using the traditional gear rack can be avoided.

In the above three embodiments, the second basket 20 is directly connected to the first basket 10 through the guide rail assembly and the anti-dropping part; the second basket 20 and the first basket 10 can also be connected indirectly, for example, the second basket 20 and the first basket 10 are connected through a connecting rod mechanism, and meanwhile, a lifting point device is arranged on the second basket 20, so that the second basket 20 can also move back and forth at two ends of the first basket 10.

Example 4:

referring to fig. 1 and 3, as an embodiment of the present invention, on the basis of the above embodiments, unlike the above embodiments, the anti-drop part 50 further includes a wear-proof plate 52, and the wear-proof plate 52 may be disposed between the anti-drop hook 51 and the basket of the second basket 20; a wear plate 52 may also be provided between the mousing-hook 51 and the first basket 10; the wear plate 52 may also be provided between the anti-drop hook 51 and the first and second baskets 10 and 20 at the same time.

The wear plate 52 may be formed by bending a sheet metal into a shape that conforms to the internal structure of the anti-drop hook 51. The wear-resistant plate 52 can be welded and fixed on the anti-disengaging hook 51, and the wear-resistant plate 52 is arranged between the anti-disengaging hook 51 and the protection body 221, so that the contact area between the anti-disengaging hook 51 and the protection body 221 is increased, the anti-disengaging capacity of the anti-disengaging hook 51 is increased, and the wear of the anti-disengaging hook 51 is reduced.

In order to further reduce the wear of the anti-drop hook 51, a rubber pad may be further provided on the side of the wear plate 52 facing the protection body 221.

In order to limit the second basket 20, a limit pin 53 is provided on at least one of the wear plate 52 and the anti-drop hook 51, a plurality of limit holes 223 are provided on the basket where the second basket 20 contacts the wear plate 52 or the anti-drop hook 51, and the limit pin 53 is inserted into any limit hole 223 to limit the second basket 20 on the first basket 10.
