[0013] Beneficial Effects

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] When loading, the utility model reverses the truck so that the carriage hits the baffle to overcome the elastic force of the torsion spring, and the baffle drives the rotating shaft to rotate downward, so that the bridge plate turns down and leans against the carriage, which is convenient for loading tobacco rods; after the truck finishes loading and drives away, the bridge plate automatically turns up under the elastic force of the torsion spring, and there is no need to manually rotate and place the bridge plate, which can reduce the labor intensity of workers and improve efficiency.

[0024] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0025] See also Figure 2 to Figure 7A tobacco rod loading platform comprises a boarding bridge body 1, and a bridge plate 2 is provided at the front end of the boarding bridge body 1. Bearing seats 3 are provided on both sides of the front end of the boarding bridge body 1, and a plurality of spaced connecting ear plates 4 are provided at one end of the bottom of the bridge plate 2. The connecting ear plates 4 are commonly connected to a rotating shaft 5, and both ends of the rotating shaft 5 are rotatably mounted on the bearing seat 3 through bearings. A plurality of spaced torsion springs 6 are provided on the periphery of the rotating shaft 5, that is, the rotating shaft 5 is penetrated by a plurality of torsion springs 6, one end of the torsion spring 6 clamps the bottom of the bridge plate 2, and the other end clamps the bottom of the boarding bridge body 1. In a natural state, the bridge plate 2 is tilted upward, and when the truck reverses, the carriage 14 will not touch the bridge plate 2, and a baffle 7 is provided at the bottom of the rotating shaft 5.

[0026] Furthermore, the upper end of the baffle plate 7 is rotatably connected to the bottom of the rotating shaft 5, and a limit plate 8 is fixedly provided on the rotating shaft 5 behind the baffle plate 7. A spring 9 is provided between the baffle plate 7 and the limit plate 8, and the elastic force of the spring 9 is greater than the elastic force of the torsion spring 6, that is, the elastic coefficient of the spring 9 is greater than the elastic coefficient of the torsion spring 6. The baffle plate 7 is located below the bridge plate 2 and extends obliquely downward.

[0027] When the carriage 14 hits the baffle 7, it first overcomes the elastic force of the torsion spring 6, and the baffle 7 drives the rotating shaft 5 to rotate downward, so that the bridge plate 2 flips down and leans against the carriage 14. At this time, the truck stops, which is convenient for loading tobacco rods. When the truck stops but fails to stop in time, the carriage 14 continues to push the baffle 7, and at this time, the elastic force of the spring 9 is overcome, and the baffle 7 can rotate backward a certain margin. At this time, the truck stops, thereby avoiding the overshoot of the truck and damaging the bridge plate 2. After the truck is loaded and leaves, the bridge plate 2 automatically flips up under the elastic force of the torsion spring 6, and there is no need to manually rotate and place the bridge plate, which can reduce the labor intensity of workers and improve efficiency.

[0028] Buffer blocks 10 are respectively provided on both sides of the front end of the boarding bridge body 1 to prevent trucks from over-rushing. Preferably, the buffer blocks 10 are made of rubber.

[0029] Furthermore, the utility model further comprises an indicator light 11, which is mounted on a building on one side of the boarding bridge body 1, so that the truck driver can see it easily. A travel switch 12 is arranged at the front end of the boarding bridge body 1, and the travel switch 12 is electrically connected to the indicator light 11. When the truck is reversed into place, the travel switch 12 is closed and the indicator light 11 is turned on. When the truck driver sees the indicator light 11, he can stop the truck immediately.

[0030] The bridge plate 2 is welded to the connecting ear plate 4. The connecting ear plate 4 is provided with a mounting hole, and the mounting hole and the rotating shaft 5 are interference fit. The rotating shaft 5 is provided with a key 13, and correspondingly, a keyway adapted to the key 13 is provided in the mounting hole.

[0031] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the utility model, which will not affect the effect of the implementation of the utility model and the practicality of the patent.
