Example 1
In this embodiment, a wheel-rail system capable of dual coupling is specifically adopted, so that a plurality of moving members 4 can share one rail, and the purposes of saving space and improving structural compactness are achieved. As shown in fig. 1, it mainly includes a base 3, a combined rail 2 provided on the base 3, a plurality of moving members 4, and a roller device 1 disposed on each of the moving members 4, thereby constituting an entire wheel-rail system. The connection relationship between the various components is: the roller devices 1 are connected to the bottom of the moving members 4, two roller devices 1 are arranged at the bottom of each moving member 4, each roller device 1 runs on the combined rail 2, the combined rail 2 is fixed on the base 3, and the roller devices 1 are placed on the combined rail 2 and are in coupling contact with the combined rail 2, so that displacement movement of the moving members 4 is realized.
In order to further realize the coupling contact between the roller device 1 and the combined track 2, as shown in fig. 1 and 4, the combined track 2 comprises a plurality of first tracks 2.1 and second tracks 2.2, wherein each first track 2.1 is arranged on one track and each second track 2.2 is arranged on the other track, the two track directions are parallel to each other, and at least one gap section is reserved in the track direction where each first track 2.1 is positioned; when the moving member 4 is in motion, the roller devices 1 of the moving member 4 are separated from or run on the combined rail 2 through the gap section, and the first rail 2.1 and the second rail 2.2 simultaneously or independently serve as bearing rail surfaces of the roller devices 1.
In order to realize stable installation of the combined track 2, as shown in fig. 5, the combined track further comprises U-shaped seats 2.3 which are arranged on the base 3 at intervals, the first track 2.1 is connected between the side surfaces of two adjacent U-shaped seats 2.3, the second track 2.2 is arranged on an open slot of the U-shaped seat 2.3, and the length of the second track 2.2 is slightly equal to that of the U-shaped seat 2.3. The first rail 2.1 is provided with a rectangular flat plate structure and is connected to the side surfaces of two adjacent U-shaped seats 2.3, and the second rail 2.2 is provided with a strip-shaped cylinder or circular tube structure and is connected above the U-shaped seats 2.3.
As shown in fig. 1 and fig. 4, the first rail 2.1 and the second rail 2.2 are arranged at intervals along the longitudinal direction, a section of overlapping area exists between the end part of the first rail 2.1 and the end part of the second rail 2.2 on the U-shaped seat 2.3, the space overlapping area of the first rail 2.1 and the second rail 2.2 on the U-shaped seat 2.3 is made to be an overlapping section, and when the roller 1.1 runs on the overlapping section, the first rail 2.1 and the second rail 2.2 are simultaneously used as bearing rail surfaces of the roller 1.1 and are respectively contacted with the first tread 1.1a and the second tread 1.1 b; when the roller 1.1 moves away from the overlap section, the first rail 2.1 or the second rail 2.2 alone serves as a support rail surface for the roller 1.1.
Since there is no shielding on the side of the middle of the first track 2.1, as shown in fig. 3, it is convenient to arrange a translation mechanism or a swing mechanism to transversely carry the moving member 4 provided with the roller device 1 along the first track 2.1 on or off (i.e. out of or into the combined track 2), thereby freeing up a track space for other moving members 4.
As shown in fig. 2 and 8, the roller device 1 includes a wheel seat 1.2 and a roller 1.1 rotatably disposed on the wheel seat 1.2, the roller 1.1 includes a first tread 1.1a and a second tread 1.1b concentrically disposed, and the first tread 1.1a and the second tread 1.1b are respectively matched with the first rail 2.1 and the second rail 2.2. In order to ensure that the roller 1.1 can be doubly coupled with the combined rail 2, the first tread 1.1a and the second tread 1.1b are respectively set to be annular cylindrical surfaces and annular arc surfaces, so that the first tread 1.1a and the second tread 1.1b can be respectively matched with the first rail 2.1 and the second rail 2.2, and further, stable operation of each roller device 1 on the moving member 4 is ensured.
As shown in fig. 5, when the roller 1.1 moves, the first tread 1.1a of the roller 1.1 is cylindrical and the second tread 1.1b is arc-shaped, and the first track 2.1 with a plate-shaped top surface being a plane is adopted to contact with the first tread 1.1a, so that the roller 1.1 can be in accessible ground track from the side surface of the first track 2.1, as shown in fig. 6 and 7, the second track 2.2 with a cylindrical shape is adopted to contact with the second tread 1.1b, and under the action of gravity, the contact point of the second tread 1.1b and the second track 2.2 is always positioned at the arc highest point of the second track 2.2, so that the symmetrical center of the second tread 1.1b coincides with the second track 2.2, thereby playing the best guiding role. Preferably, the radius of the arc of the second tread 1.1b is slightly larger than the radius of the second track 2.2 matched with the second tread to reduce the difficulty of matching the wheel and the track, so that the roller 1.1 slides smoothly, and protruding rims 1.1c are arranged on two sides of the second tread 1.1b to prevent the roller 1.1 from falling off the second track 2.2 in the running process.
As shown in FIG. 5, the roller 1.1 is made into a revolving body with a round hole in the center and 2 treads on the periphery, a wheel shaft 1.5 is installed in the round hole of the roller 1.1 through a rolling bearing 1.3, a wheel seat 1.2 is made into a square frame shape with an opening at the bottom, the wheel shaft 1.5 is installed on the wheel seat 1.2, a retainer ring 1.4 positioned between the wheel seat 1.2 and the roller 1.1 is sleeved on the wheel shaft 1.5, the retainer ring 1.4 is in a ring shape, the wheel shaft 1.5 is a cylinder with steps, the roller 1.1, the rolling bearing 1.3 and the retainer ring 1.4 are connected on the wheel seat 1.2 through the wheel shaft 1.5, wherein the rolling bearing 1.3 is arranged in the roller 1.1 to reduce rolling resistance, and the retainer ring 1.4 is arranged between the wheel seat 1.2 and the rolling bearing 1.3 to prevent the roller 1.1 from moving along the wheel shaft 1.5.
For better matching the movement of the roller 1.1, as shown in fig. 5, the first rail 2.1 and the second rail 2.2 are staggered by a certain distance in the transverse direction (perpendicular to the rail track direction), so that a space is reserved for the rim 1.1c of the roller 1.1 to pass through, the relative height and the transverse distance of the first rail 2.1 and the second rail 2.2 are matched with the first tread 1.1a and the second tread 1.1b of the roller 1.1, the first tread 1.1a can be contacted with the top surface of the first rail 2.1 when the roller 1.1 passes through a superposition area, meanwhile, the second tread 1.1b can also be contacted with the top surface of the second rail 2.2, and the first rail 2.1 and the second rail 2.2 simultaneously support the roller device 1 and a moving member 4 carried by the roller device 1; when the roller device 1 leaves the overlapping area, the roller device can be smoothly switched to the first track 2.1 or the second track 2.2, so that the roller device 1 can continuously run within the length range of the combined track 2.
The invention is not limited to the above-described alternative embodiments, and any person who may derive other various forms of products in the light of the present invention, however, any changes in shape or structure thereof, all falling within the technical solutions defined in the scope of the claims of the present invention, fall within the scope of protection of the present invention.
