The two ends of the driving shaft and the driven shaft extend out of the guide rail and are rotatably connected to the bearings arranged in the tensioning plate. One end of the driving shaft is provided with a motor fixed to one side of the guide rail. The endless belt cooperates with the driving plate, and friction is generated by the contact between the driving plate and the endless belt and the tension spring, thereby driving the transport vehicle to move.

[0011] Furthermore, in the above-mentioned light-load suspension belt conveyor system, the ends of the connecting crossbeam are provided with buffer plates, and the buffer plates at the front end of the moving direction are provided with buffer sleeves, and the buffer sleeves are made of elastic plastic. When accumulating, the rear transport vehicle approaches the front transport vehicle, and the buffer sleeves provide a buffer force to the front vehicle, thereby reducing the vibration caused by the collision, increasing the service life of the equipment, and preventing the items on the transport vehicle from falling due to the collision.

[0014] Furthermore, in the above-mentioned light-load suspended belt conveyor system, the positioning platform is concentric with one of the guide wheels, one end of the tension spring is sleeved on the positioning platform, and the other end is sleeved on the connecting screw above the guide wheel.

Guide wheels 313 are provided on both sides below the vehicle body 311. The guide wheels 313 cooperate with the slide groove 23 and are slidably connected with the slide groove 23 to guide the moving direction of the transport vehicle 3, so that the transportation of the transport vehicle 3 is faster and more stable.

[0051] like Figure 5 , 10 As shown, a load-bearing shaft 34 connected to the vehicle body 311 is provided between the two guide wheels 313. The load-bearing shaft is located at the optimal stress point of the vehicle body so that the stress of the vehicle group is balanced. Load-bearing sleeves 331 are provided in the through holes at both ends of the connecting beam 33 to enhance the strength of the connection. The load-bearing shaft 34 is sleeved in the load-bearing sleeves 331 and is connected to the connecting beam 33 through a limiting ring 35 and a double nut. The connection is simple, convenient and firm.

[0052] The ends of the connecting crossbeam 33 are provided with buffer plates 332, and the buffer plates 332 at the front end in the moving direction are provided with buffer sleeves 333, and the buffer sleeves 333 are made of elastic plastic. When stacking, the rear transport vehicle approaches the front transport vehicle, and the buffer sleeves 333 provide a buffer force to the front vehicle, reducing the vibration caused by the collision, increasing the service life of the equipment, and preventing the items on the transport vehicle from falling due to the collision.

[0053] The working principle of the light load suspension belt conveyor system of the present invention is as follows: Figure 8 As shown, when it is necessary to stop the accumulation, the front transport vehicle moves to the tail of the guide rail 2, the cylinder 42 of the stopper 4 extends, the first brake wheel 317 of the front transport vehicle contacts the brake plate 314, and the second brake wheel 322 contacts the stopper 4 limit plate 44, so that the connecting rod 315 descends along the guide groove 3111, the driving plate 314 leaves the annular belt 11, and the front transport vehicle switches to a powerless state. At the same time, the stopper limit rod 46 blocks the connecting rod 315 to prevent the front transport vehicle from moving forward due to inertia. At this time, the front transport vehicle stops, and the rear transport vehicle moves close to the front transport vehicle. At this time, the first driving wheel 317 of the front vehicle group 31 of the rear transport vehicle contacts the brake 321 of the rear vehicle, and the driving plate 314 of the front vehicle group of the rear transport vehicle separates from the annular plate 11 and is in a powerless state. In this cycle, the subsequent transport vehicles are switched to a powerless state in turn, and the transport vehicles 3 stop in turn, and the conveying system changes to an accumulation state. It is achieved that only one stopper is used to stop multiple transport vehicles, thereby reducing the manufacturing cost of the suspension conveying system and reducing the probability of error.

[0054] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
