And the contact point with the ground as the support device can be regarded as the fulcrum of the lever. When the frame is under unbalanced force, it will rotate around this lever fulcrum, resulting in the influence on the stability of the equipment and even causing equipment damage.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] The present utility model provides a telescopic conveyor with a weight balancing function, enabling the support mechanism of the conveyor main frame to move synchronously and in the same direction as the telescopic frame, and synchronously adjusting the grounding position of the support mechanism when the center of gravity of the overall frame changes, ensuring that the center of gravity of the overall frame always remains between the grounding end of the main frame and the grounding position of the support frame, making the frame stable.

[0033] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following further details the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0034] As Figure 1-4 shown, the present utility model provides a telescopic conveyor with a weight balancing function, including a main frame 1, a telescopic frame 2 that reciprocates axially in the main frame 1, and a support device 3 that moves in the same direction as the telescopic frame 2. The main frame 1 is an inclined structure, with the lower end being the grounding end and the higher end being the extending end. The telescopic frame 2 extends from the extending end. The support device 3 contacts the ground. During the extension process of the telescopic frame 2, the center of gravity of the overall frame formed by the main frame 1 and the telescopic frame 2 will continuously move in the extending direction of the telescopic frame 2. Since the ground contact point of the support device 3 can be regarded as a lever fulcrum, when the center of gravity of the overall frame is on the right side of the ground contact point of the support device 3, there will be a problem that the overall frame rotates around the ground contact point of the support device 3 and then topples. Therefore, in this application, the support device 3 moves synchronously and in the same direction as the telescopic frame 2. During this process, the center of gravity of the overall frame always remains between the grounding end of the main frame 1 and the ground contact point of the support device 3 until the telescopic frame 2 moves to the limit position, avoiding the problem of the overall frame toppling. A power assembly for driving the telescopic frame 2 and the support device 3 to move is provided on the main frame 1. The power assembly can be a device that can provide power to the telescopic frame 2 and the support device 3 simultaneously, or a combination of two sets of devices that respectively provide power to the telescopic frame 2 and the support device 3.

[0035] As Figure 1-4As shown, in a preferred embodiment, traveling wheels 31 are installed on the support device 3. The traveling wheels 31 are in contact with the ground. The traveling wheels 31 can convert sliding friction into rolling friction, making it more convenient for the support device 3 to move. At the same time, the telescopic conveyor with a weight balance function equipped with the traveling wheels 31 can be directly towed by a trailer, facilitating the transportation and placement of the telescopic conveyor with a weight balance function. When the convenience of transportation is not considered, the traveling wheels 31 can also be replaced with structures such as crawlers and auxiliary wheels, or the support device 3 can be placed on a track and sliding members matching the track can be installed at the bottom of the support device 3.

[0036] The power assembly includes a power component, a first drive component, and a second drive component. The first drive component is arranged on the telescopic frame 2, and the input end of the first drive component is connected to the first output end of the power component; the second drive component is arranged on the support device 3, and the input end of the second drive component 5 is connected to the second output end of the power component, as Figure 2 and 4 As shown, in a preferred embodiment, the second drive component includes a second rack 51 and a fourth gear 52 meshing with the second rack 51. The second rack 51 is arranged on the top of the support device 3, and the fourth gear 52 is connected to the second output end of the power component.

[0037] As Figure 1 and 3 As shown, the sliding component includes a slide rail 11. A first pulley 12, a second pulley 13, and a third pulley 14 are installed in the slide rail 11. The first pulley 12, the second pulley 13, and the third pulley 14 are connected to the support device 3 through a mounting plate 15. When the support device 3 moves, the first pulley 12, the second pulley 13, and the third pulley 14 roll along the slide rail 11, minimizing the resistance received by the support device 3. The slide rail 11 also plays a limiting role to prevent the support device 3 from separating from the main frame 1.

[0038] As Figure 2 and 4 As shown, the first drive component includes a first rack 41 and a first gear 42. The first rack 41 is installed at the bottom of the telescopic frame 2. The first gear 42 meshes with the first rack 41, and the first gear 42 is connected to the first output end of the power component. In a preferred embodiment, the first drive component 4 further includes a first sprocket 43, a chain 44, and a second sprocket 45 for transmission. The chain 44 meshes with the first sprocket 43 and the second sprocket 45, and the second sprocket 45 and the first gear 42 are coaxially arranged.

[0039] As Figure 2 and 4 shown, in a preferred example, the power assembly is a set, the power assembly includes an engine 61 and a speed reducer 62, the output end of the engine 61 is connected to the input end of the speed reducer 62, and the two output ends of the speed reducer 62 are respectively the first output end of the power assembly and the second output end of the power assembly.

[0040] The engine 61 is an electric motor, and the engine can also be a steam engine, a diesel engine or a gasoline engine.

[0041] As Figure 5 and 6 shown, the present utility model further includes a conveyor belt 7 and a conveyor belt movement assembly, the conveyor belt 7 and the conveyor belt movement assembly are installed on the main frame 1 and the telescopic frame 2, the conveyor belt movement assembly includes a driving roller 81, a deflecting roller 82, a deflecting roller 83, a deflecting roller 84 and a deflecting roller 85, the driving roller 81, the deflecting roller 84 and the deflecting roller 85 are installed on the main frame 1, the deflecting roller 82 and the deflecting roller 83 are installed on the telescopic frame 2, and the conveyor belt 7 is wound around the driving roller 81, the deflecting roller 82, the deflecting roller 83, the deflecting roller 84 and the deflecting roller 85.

[0042] The conveyor belt 7 can be deformed following the movement of the telescopic frame 2. When the telescopic frame 2 does not extend, a part of the conveyor belt 7 is stored between the telescopic frame 2 and the main frame 1. When the telescopic frame 2 continuously extends outwards, the stored part of the conveyor belt 7 is continuously supplemented to the extended part of the telescopic frame 2 until the telescopic frame 2 reaches the limit position.
