In the embodiment of the utility model, the track-changing device further comprises a blocking plate 4, which is arranged at the lower side of the main track 8, and the blocking plate 4 is positioned below the front cut-off section of the cut-off position on the main track 8 based on the running direction of the carrier on the main track 8, so as to block the carrier from falling off.

In the embodiment of the utility model, the output end of the lifting device 1 stretches in the vertical direction, so that the lifting block 3 is driven to lift in the vertical direction; when ascending, the lifting block 3 can enter the cut-off position of the main rail 8 and is basically at the same height as the main rail 8, so that a transmission relation between a carrier on the lifting block and a driving device of the main rail 8 can be established.

In a specific embodiment, the stop plate 2 may be disposed on the lower side of the base plate 11, and the stop plate 2 is disposed near the end of the guide rail 9, so as to block the end of the guide rail 9 during the lifting process of the lifting block 3, so that the subsequent carriers on the guide rail 9 are stopped from falling. It will be appreciated that the stop plate 2 is arranged vertically and its length should be greater than the lifting travel range of the lifting block 3, so that the stop plate 2 can always block the end of the guide rail 9 during lifting of the lifting block 3.

The width of the stop plate 2 is larger than the diameter of the guide rail 9, and the stop plate 2 can be provided with a vertical concave area at the tail end of the guide rail 9, so that part of the structure at the tail end of the guide rail 9 can be positioned in the concave area, the two sides of the stop plate 2 directly abut against the carrier at the tail end of the guide rail 9, the basic hanging posture of the carrier is ensured, and the carrier can slide down onto the lifting block 3.

In the utility model, the lifting block 3 can be in butt joint with the main rail 8 when ascending and in butt joint with the tail end of the guide rail 9 when descending; the tail end of the guide rail 9 is in an inclined posture, the carrier slides downwards at the tail end of the guide rail 9 through self gravity, and the lifting block 3 is required to keep the inclined posture at the same angle with the guide rail 9 in order to slide downwards smoothly; the main rail 8 is in a horizontal posture, the carrier is driven on the main rail 8 by a driving device carried by the main rail 8, and in order to ensure the stability of the transmission relationship between the carrier and the driving device, the lifting block 3 should maintain the same horizontal posture as the main rail 8.

In the embodiment of the utility model, the inclined posture of the lifting block 3 can be matched with the position stability of the carrier in the stable lifting process of the blocking plate 4. Due to inertia of the carrier on the guide rail 9, when the lifting block 3 is in butt joint with the guide rail 9, the carrier can slide down onto the lifting block 3, so that the carrier is ensured not to drop off/return to the guide rail 9 again in order to stabilize the stability of the carrier on the lifting block 3, and a limiting included angle can be arranged between the lifting block 3 and the blocking plate 4, so that the position of the lifted carrier is stabilized, and the lifted carrier is prevented from shaking.

As a preferred embodiment, the rotation angle of the rotation connection between the lifting block 3 and the base 12 may be greater than 180 °, so that the lifting block 3 has an inclined posture (relative to the blocking plate 4), and after the lifting block 3 is located in the area of the lifting block 3, the lifting block is slid down along the upper surface of the lifting block 3, and the lifting block is limited by using the limiting included angle formed between the inclined posture lifting block 3 and the vertically arranged blocking plate 4, so as to ensure the stability of the lifting block 3; specifically, the bottom of the side, close to the blocking plate 4, of the lifting block 3 is provided with a magnet 7, and the base 12 is made of a magnetic material or a part of the base 12 is made of a magnetic material, such as iron, so that an adsorption effect can be generated between the magnet 7 and the base 12, and the basic posture of the lifting block 3 in a normal state is changed. Normal means that the lifting block 3 does not reach the height of the main rail 8.

When the lifting block 3 is not acted by external force, one side of the lifting block 3, which is close to the blocking plate 4, rotates downwards to be adsorbed to the base 12, so that one end of the lifting block 3, which is close to the blocking plate 4, rotates downwards, and the whole lifting block 3 is inclined, so that a limiting included angle is formed between the lifting block 3 and the blocking plate 4; when the carrier slides down onto the lifting block 3 from the guide rail 9, the carrier slides down into the limiting included angle directly. When the lifting block 3 ascends, the angle of the limiting included angle is unchanged.

It can be understood that the inclination angle generated by the influence of the magnetic force on the lifting block 3 is the same as the inclination angle of the tail end of the guide rail 9, so that the lifting block 3 can be connected to the tail end of the guide rail 9 in a homeotropic manner, and the carrier on the guide rail 9 is guided to slide down onto the lifting block 3 and is limited by the limiting included angle.

In the utility model, the height of the lifting block 3 is gradually consistent with that of the main rail 8 in the lifting process, but the lifting block 3 in a normal state is in an inclined posture, so that a new limiting included angle can be formed between the lifting block and the cut-off surface of the main rail 8, and the operation of the carrier on the main rail 8 is influenced.

It will be appreciated that the flush effect between the lifting block 3 and the main rail 8 is adjusted by adjusting the thickness of the alignment step 15.

According to the utility model, the lifting block 3 can be divided into the magnetic attraction end and the pressing end by taking the rotation connection part of the plug-in column 13 as a boundary, the magnetic attraction end ensures that the posture of the lifting block 3 is consistent in a normal state, the inclined butt joint effect with the tail end of the guide rail 9 is stable, and a limiting included angle can be formed with the blocking plate 4 to limit the carrier when the carrier is driven to rise; the pressing end ensures the horizontal butt joint effect of the lifting block 3 and the main rail 8 when the main rail is in butt joint by ascending.

It will be appreciated that the range of travel of the base plate 11 and the output end is substantially consistent, taking into account the dimensions of the base 12 and the lifting block 3 itself when interfacing with the main rail 8 and the guide rail 9. As a preferred embodiment, the lowest part of the lifting travel of the lifting device 1 is lower than the end of the guide rail 9, so that the lifting block 3 can be docked with the guide rail 9, thereby guiding the carrier onto the lifting block 3; the highest position of the lifting travel of the lifting device 1 is lower than the cut-off of the main rail 8, so that the lifting block 3 can be flush with the main rail 8, and the carrier is lifted to the effective driving range of the driving device and is pushed by the driving device to run along the main rail 8.
