[0027] refer to Figure 1-Figure 2 The present invention discloses a conveyor track for a trolley 5. The trolley 5 is used to support a conveyor belt. The conveyor belt is loaded with materials and is driven by a drive device to circulate along the conveying direction. The trolley 5 also moves along the conveying direction due to the friction between the trolley 5 and the conveyor belt. In some embodiments, the carrying track 1 includes an upper track 101 and a lower track 102. The upper track 101 carries the trolley 5 from the material drop end to the material discharge end, and the lower track 102 carries the trolley 5 for the return trip.

[0028] The conveyor's trolley track includes a load-bearing track 1, a track support frame 2, and an auxiliary track 3. The load-bearing track 1 and the auxiliary track 3 are respectively fixedly connected to the track support frame 2. The load-bearing track 1 is used to carry the trolley 5 and run along the load-bearing track 1. The auxiliary track 3 includes a limiting track 302 and a transverse support portion 301. The limiting track 302 is fixedly connected to the transverse support portion 301, and the transverse support portion 301 is connected to the track support frame 2. The limiting track 302 is at least partially located above the track surface of the load-bearing track 1. The minimum distance between the limiting track 302 and the load-bearing track 1 on the normal plane of the load-bearing track 1 is greater than the diameter of the wheel 501 of the trolley 5. Therefore, under normal operating conditions, the wheel 501 of the trolley 5 runs on the load-bearing track 1, and the upper end of the wheel 501 does not contact the limiting track 302, which can ensure the vehicle's efficient operation with low friction resistance. If the wire rope between the trolleys 5 becomes loose, the wheels 501 become worn, the frame deforms, or the track shape changes, and the trolley 5 jumps off the load-bearing track 1, the auxiliary rails 3 limit the displacement of the wheels 501 of the trolley 5, so that the wheel rims 502 do not exceed the top surface of the limit rails 302. The wheel rims 502 also limit the left and right displacement of the trolley 5, thereby preventing derailment accidents. At the same time, the auxiliary rails 3 also limit the upward jump of the trolley 5, preventing the problem of excessive movement of conveyor belt materials on the conveyor belt due to excessive jump of the trolley 5.

[0029] In some embodiments, the track support frame 2 includes track legs 6, which are spaced apart along the direction of the trailer track and are used to install the load-bearing track 1 and the auxiliary track 3 at a specified height. The lateral support portion 301 of the auxiliary track 3 is fixedly connected to the track legs 6, and the limiting track 302 is then installed on the lateral support portion 301. Such an arrangement not only ensures the anti-derailment function of the auxiliary track 3, but also minimizes the steel consumption of the auxiliary track 3. Preferably, the lateral support portion 301 is fixedly connected to the track legs 6 by bolts or welding.

[0030] In some embodiments, the lower surface of the limiting rail 302 is parallel to the track surface of the supporting rail 1, and the friction coefficient of the lower surface of the limiting rail 302 is greater than the track surface of the supporting rail 1, so as to reduce the speed of the trolley 5 after it leaves the track surface and reduce the jumping amplitude.

[0031] In some embodiments, on the normal plane of the load-bearing rail 1, the minimum distance between the limiting rail 302 and the tread of the wheel 501 of the trailer 5 is less than the height of the wheel rim 502 of the trailer 5. Furthermore, the inner crotch distance of the limiting rail 302 is equal to or greater than the inner crotch distance of the load-bearing rail 1 and less than the outer wheel distance of the trailer 5. With this arrangement, during normal driving conditions, the wheel rim 502 does not rub against the limiting rail 302, thereby preventing the negative impact of increasing the resistance of the trailer 5.

[0032] In some embodiments, the auxiliary rail 3 is installed at intervals according to the path conditions of the trailer track, that is, the auxiliary rail 3 is installed on the section where the trailer 5 is likely to derail. Preferably, the auxiliary rail 3 is arranged above the track surface of at least one of the concave arc section, convex arc section or turning section of the load-bearing track 1. In some embodiments, the auxiliary rail 3 is also provided with a guide rail 4, which is arranged at the starting position where the trailer 5 enters the auxiliary rail 3, and the minimum distance between the guide rail 4 and the load-bearing track 1 in the normal direction of the track surface of the load-bearing track 1 changes from large to small from the direction of travel of the trailer 5. With such an arrangement, the trailer 5 passes through the guide rail 4 before entering the limiting track 302, so as to avoid the trailer 5 wheel 501 jumping when entering the auxiliary rail 3 and colliding with the side end face of the limiting track 302, thereby reducing the possibility of accidents.

[0033] In some embodiments, the limiting rail 302 may be C-shaped, L-shaped, rectangular, or circular on the normal plane of the supporting rail 1 .

[0034] The present invention also provides a belt conveyor comprising a trolley 5, a conveyor belt, and a drive mechanism. The wheels 501 of the trolley 5 are provided with wheel rims 502 on their inner sides. The trolley 5 also comprises the trolley rails of the belt conveyor in any of the above-mentioned embodiments. Thus, while maintaining the advantages of low resistance and high operating speed of the wheel-rail conveying method, safety can also be ensured to the greatest extent possible.

Each embodiment focuses on the differences between the other embodiments. In particular, the system embodiments are generally similar to the method embodiments, so the description is relatively simple.
