The roller assembly 330 includes an upper traveling wheel 331 that moves along the bottom surface of the upper track 100. The upper traveling wheel 331 is mounted on the mounting seat 333 of the roller assembly 330 through a floating mechanism 332 so that the upper traveling wheel 331 adaptively fits the bottom surface of the upper track 100.

[0030] The lower rail 200 can be installed on a predetermined foundation, such as on the ground or on a platform at a certain height. There are two lower rails 200 arranged in parallel. The specific shape of each lower rail 200 can be designed as needed, such as a rail with a triangular cross-section, an I-beam rail, a channel steel, or other feasible structures; no limitation is made here. The upper rail 100 can be fixed to the ceiling or to a bracket. The upper rail 100 can also be a known feasible structure, such as a rectangular tube, or of course, a channel steel or an I-beam, etc.; no limitation is made here.

[0031] As attached Figure 1 As shown, the lifting and transferring trolley 300 includes a traveling base 350. The traveling base 350 can adopt a known traveling structure of a rail-guided trolley, which will not be described in detail here. The traveling base 350 is movably mounted on two lower tracks 200 via a set of lower traveling wheels 351. A column 310 is provided on the traveling base 350, and a lifting mechanism is provided at the column 310. The lifting mechanism includes, for example, a vertically arranged servo module. The servo module is connected to a support plate 370, a telescopic fork, or a conveyor and drives the support plate, telescopic fork, or conveyor to move up and down. Of course, in other embodiments, the lifting mechanism can also be other feasible mechanisms, which are not limited here.

[0032] The number of roller assemblies can be designed as needed; preferably, two roller assemblies are provided on the top of each column.

[0033] In order to enable the lifting and transfer trolley 300 to move more stably along the upper track 100, as shown in the attached... Figure 2 As shown, there are two upper traveling wheels 331, each connected to the mounting base 333 via a floating mechanism 332. A mounting plate 334 is provided on the mounting base 333 between the two upper traveling wheels 331. A guide wheel 335 is provided on the mounting plate 334, with the axis of the guide wheel 335 extending vertically. The number of guide wheels can be designed as needed; for example, there can be only one guide wheel 335. In this case, the upper track 100 can be a C-shaped track, and the guide wheel 335 is located within the groove of the upper track 100 and moves between the inner walls of the groove.

[0034] In another embodiment, there are two guide wheels 335. In this case, the two guide wheels 335 are movably disposed on both sides of the upper rail 100. Correspondingly, the upper rail 100 is a rectangular tube or an I-shaped guide rail.

[0035] As attached Figure 3As shown, the floating mechanism 332 comprises a floating frame which is vertically movable relative to the mounting base 333, the floating frame comprises a U-shaped wheel frame 301, a supporting shaft is arranged on the U-shaped wheel frame 301, the upper walking wheel 331 is rotatably arranged on the supporting shaft through a bearing, and an elastic member 302 is arranged between the floating frame and the mounting base 333 to apply an upward pressure to the floating frame.

[0036] Further, in order to prevent the floating frame from being pulled out from the top of the mounting base 333, the floating frame further comprises a guide shaft 303 which is connected below the U-shaped wheel frame 301 and is vertically movably arranged on the mounting base 333, the lower end of the guide shaft 303 extends below the mounting base 333 and is connected with a stopper 304, the size of the stopper is larger than the size of a through hole on the mounting base through which the guide shaft passes, so that the stopper can block the guide shaft from being pulled out from the through hole.

[0037] In addition, in order to make the guide shaft 303 move more smoothly, the guide shaft 303 is movably arranged on a shaft sleeve or a linear bearing 305 in the mounting base 333, the elastic member 302 is a spring which is sleeved on the outer periphery of the guide shaft 303, one end of the spring abuts against the bottom of the U-shaped wheel frame 301, and the other end of the spring abuts against the top of the shaft sleeve or the linear bearing 305, and the spring is kept in a compressed state in a normal state, so that the upward jacking force applied to the floating frame by the elastic member can be continuously maintained to make the upper walking wheel 331 fully fit the upper track 100.

[0038] More preferably, in order to facilitate the jacking force applied to the floating frame by the elastic member, the floating frame is movably arranged on an adjusting block 306 in the mounting base 333 in the vertical direction, the adjusting block 306 is adjustably arranged in the mounting base 333. Specifically, the shaft sleeve or the linear bearing 305 on which the floating frame is arranged is fixed on the adjusting block 306, the adjusting block 306 is movably arranged in the mounting base 333 in the vertical direction, and at least one adjusting bolt 307 is threadedly connected to the mounting base 333, the adjusting bolt 307 extends into the mounting base 333 from the bottom of the mounting base 333 and abuts against the bottom of the adjusting block 306. More preferably, the adjusting bolt 307 is two and symmetrically abuts against the two sides of the adjusting block 306, when it is needed to increase the jacking force of the elastic member 302, the adjusting bolt 307 can be screwed to move upward so as to push the adjusting block 306 to move upward relative to the mounting base 333, so as to achieve the purpose of adjusting the jacking force.

[0039] Further, in order to avoid the adjusting block 306 from moving up and down in the mounting base 333, as shown in FIG. 4, a limiting block 308 is arranged on the mounting base 333, the limiting block 308 is arranged on the mounting base 333 and is located below the adjusting block 306, and the limiting block 308 is arranged on the mounting base 333 and is located below the adjusting block 306. Figure 4As shown, the mounting seat 333 is locked with the adjusting block 306 through a locking bolt 308, the mounting seat 333 is formed with a waist-shaped hole 309 for the locking bolt 308 to pass through, the waist-shaped hole 309 extends in the vertical direction, so that when the height of the adjusting block 306 needs to be adjusted, the locking bolt 308 is loosened, then the adjusting bolt 307 is screwed to adjust the height of the adjusting block 306, after the adjustment is completed, the locking bolt 308 is tightened again to fix the adjusting block 306 with the mounting seat 333.
