[0002] Conveyor belts and belt conveyors are widely used in agriculture, industrial and mining enterprises, and transportation industries to transport various solid block and powder materials or finished items. Conveyor belts can transport continuously, efficiently, and at a large angle. Conveyor belts are safe to operate, easy to use, easy to maintain, and have low freight costs. They can also shorten transportation distances, reduce project costs, and save manpower and material resources. Therefore, they are widely used in cement, coking, metallurgy, chemical, steel and other industries where the transportation distance is short and the transportation volume is small.

[0003] Since the conveyor belt is long, there are too many detours to the other side, which greatly affects the efficiency of the inspection work of the conveyor belt.

[0023] When it is necessary to install a ladder on the conveyor belt 1, the two fixing frames 2 can be moved to both sides of the conveyor belt 1 first. At this time, the connecting plate 3 can be installed on the upper ends of the two fixing frames 2. When rain falls on the connecting plate 3 in an outdoor environment, the rain will flow along the water trough 32 on the connecting plate 3. When it is necessary to pass through the conveyor belt 1, the handrail 21 can be used to climb onto the connecting plate 3. When walking on the connecting plate 3, the guardrail 31 has a certain protective effect on the staff. The device sets both sides of the ladder on the ground near the conveyor belt 1, and the fixing frames 2 and connecting plates 3 on both sides can be moved, which is flexible to use.

[0024] Example 2

[0025] See also Figure 2-Figure 4 Both sides of the two fixing frames 2 are provided with diversion holes 22, and the water trough 32 is connected with the diversion holes 22. With the cooperation between the fixing frames 2, the diversion holes 22 and the water trough 32, rainwater can be directly discharged from the fixing frames 2 to the outside through the water trough 32 and the diversion holes 22.

[0026] Connecting plate 2 33 is fixedly installed on both sides of connecting plate 1 3, and the adjustment component 4 includes an adjustment block 41 slidably installed in the slot 23. A slot 42 is provided on the upper end of the adjustment block 41, and one side of connecting plate 2 33 is slidably connected in the slot 42. With the cooperation between connecting plate 1 3, connecting plate 2 33, slot 23, adjustment block 41 and slot 42, connecting plate 1 3 and adjustment block 41 are connected together through connecting plate 2 33.

[0027] The two fixing frames 2 are both rotatably connected with a rotating rod 43, and a gear 44 is fixedly installed on the rotating rod 43. A mounting groove 46 is opened inside the adjusting block 41, and the rotating rod 43 and the gear 44 are both rotatably connected in the mounting groove 46. With the cooperation between the fixing frame 2, the rotating rod 43, the gear 44, the adjusting block 41 and the mounting groove 46, the rotating rod 43 and the gear 44 can rotate in the mounting groove 46.

[0028] A rack plate 45 is fixedly mounted on one side wall of the mounting groove 46 , and the rack plate 45 meshes with the gear 44 . With the cooperation among the mounting groove 46 , the rack plate 45 and the gear 44 , the adjusting block 41 can be lifted upward when the rotating rod 43 rotates.

[0029] A handle 24 is fixedly mounted on one side of the rotating rod 43 , and the handle 24 is rotatably connected to the side wall of the fixing frame 2 . With the cooperation among the rotating rod 43 , the handle 24 and the fixing frame 2 , the rotating rod 43 can be driven to rotate by rotating the handle 24 .

[0030] When it is necessary to install a ladder on the conveyor belt 1, first place the fixing frame 2 on both sides of the conveyor belt 1, and place the connecting plates 2 33 on both sides of the connecting plate 1 3 into the card slots 42 on the adjusting blocks 41 on both sides respectively, to complete the installation and fixation of the connecting plate 1 3. When the goods transported on the conveyor belt 1 at the lower end are large, the connecting plate 1 3 may affect the transportation of the goods. At this time, the handle 24 on the side of the fixing frame 2 can be rotated. When the handle 24 is rotated, the rotating rod 43 can be driven to rotate in the installation groove 46. When the rotating rod 43 rotates, it drives the gear 44 to rotate, and the gear 44 rotates to drive it and the gear 44 to rotate. The meshing rack plate 45 moves, and when the rack plate 45 moves, it drives the adjustment block 41 to slide upward along the side wall of the slot 23. When the adjustment block 41 moves, it drives the upper connecting plate 3 to be lifted upward at the same time, so that larger goods can pass through the lower end of the connecting plate 3. When rainwater falls on the upper end of the connecting plate 3, the rainwater can flow into the guide hole 22 along the gutter 32 and finally flow out. When the goods transported by the conveyor belt 1 at the lower end of the device are higher, the height of the connecting plate 3 can be adjusted by rotating the handles 24 on both sides, and the rainwater can flow out through the gutter 32 and the guide hole 22.
