[0015] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0016] Embodiment 1

[0017] Please refer to Figure 1 , a movable pedestrian bridge across the belt conveyor, which is used to be installed across and movably above the belt conveyor 1, and includes a bridge 2, a ladder 3 and walking wheels 4. A bridge opening for the belt conveyor 1 to pass through is formed at the lower part of the bridge 2. The two ladders 3 are oppositely arranged on both sides of the bridge 2, and several walking wheels 4 are oppositely arranged at the bottom of both sides of the bridge 2. In this embodiment, a toolbox for storing maintenance tools is installed on the bridge.

[0018] By installing the bridge 2 on the belt conveyor 1, the belt conveyor 1 is located inside the bridge opening, and it can be moved to any position of the belt conveyor 1 through the walking wheels 4 for maintenance, without the need to shut down the belt conveyor 1, climb over the belt conveyor 1, or go around the head and tail of the belt conveyor 1 back and forth, which saves time and effort, reduces the labor intensity of maintenance personnel, improves the maintenance efficiency, and at the same time reduces the probability of belt injury accidents and improves the safety of maintenance; moreover, it also improves the efficiency of leakage cleaning, and reducing the number of times the belt conveyor is stopped helps to improve the operating efficiency of the belt conveyor 1.

[0019] The bridge frame 2 serves as the main body of the entire device, including a middle arch portion and walking portions respectively connected to the bottom ends on both sides of the middle arch portion. The walking wheels 4 are movably arranged on the bottom surface of the walking portions. In this embodiment, the middle arch portion is in a "Π" shape, and its top surface forms a bridge deck for walking. The middle arch portion can also be in structures such as a "∩" shape. During maintenance, maintenance personnel move to both sides of the belt conveyor 1 through the ladder 3 and the bridge deck for maintenance; on the bridge deck of the middle arch portion, there is a swing-open hanging plate (not shown in the figure). The operation condition of the belt conveyor 1 can be observed by opening the hanging plate, and maintenance can also be carried out by opening the hanging plate when the belt conveyor 1 is shut down.

[0020] Among them, the middle arch portion and the walking portions are of an integrally formed structure.

[0021] Preferably, an inner right-angle structure is formed at the connection between the middle arch portion and the walking portions. The ladder 3 is arranged at the inner right-angle structure. The upper end of the ladder 3 is connected to both ends of the top surface of the middle arch portion, and the lower part of the ladder 3 is connected to the edge of the walking portion.

[0022] Preferably, handrails 5 are arranged on both sides of the top surface of the middle arch portion and on both sides of the ladder 3 to ensure the safety of personnel passing.

[0023] The walking wheels 4 are the key structures to ensure the movement of the entire device. In this embodiment, the number of the walking wheels 4 is eight. Four of the walking wheels 4 are arranged in a square matrix on the bottom surface of one of the walking portions, and the remaining four walking wheels 4 are arranged in a square matrix on the bottom surface of the other walking portion. The walking wheels 4 are bidirectional wheels and can only move back and forth along the conveying direction of the belt conveyor 1 and cannot move left and right to both sides of the belt conveyor 1, so as to ensure that the movable pedestrian bridge always runs in a straight line on the center line of the belt conveyor 1.

[0024] Embodiment 2

[0025] A belt conveying device includes a belt corridor 6, a belt conveyor 1, and a movable pedestrian bridge spanning across the belt conveyor. The belt conveyor 1 is laid in the belt corridor 6, and the belt corridor 6 plays a role in protection to avoid affecting the products on the belt due to dust and the like. The movable pedestrian bridge is straddled on the belt conveyor 1 for maintenance and operation personnel to cross the belt conveyor 1 and move to both sides of it, thereby improving the maintenance and operation efficiency.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
