Description

Technical Field

[0001] This utility model relates to the field of mining machinery, specifically to a lifting platform and a ore chute dredging device with the lifting platform. Background Technology

[0002] In existing mining lifting platforms, the lifting mechanism can typically only achieve vertical lifting movement, but cannot perform horizontal translation. This deficiency makes it difficult for workers to accurately position the lifting platform in narrow or complex mine environments, requiring manual pushing or the use of other equipment for movement, which not only reduces work efficiency but also poses safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a lifting platform and a mine chute dredging device with the lifting platform, which solves the problem that existing lifting mechanisms can usually only achieve vertical lifting movement and cannot perform horizontal translation adjustment.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: a lifting platform, comprising a sliding platform base and a lifting platform body slidably disposed on the sliding platform base; The sliding platform base is hinged to a support leg on its side wall. A linkage is provided between the support leg and the main body of the lifting platform. The linkage is used to drive the support leg to rotate up and down when the main body of the lifting platform slides.

[0005] Preferably, the support leg is located on the moving path of the lifting platform body.

[0006] Preferably, the sliding platform base is provided with a driving component for driving the main body of the lifting platform to move horizontally.

[0007] Preferably, the support leg includes a bracket and a telescopic leg disposed on the bracket.

[0008] Preferably, the sliding platform base is provided with a mounting seat on its side wall, the bracket is hinged to the mounting seat, the linkage is a flexible connector, and the two ends of the flexible connector are respectively connected to the bracket and the lifting platform body.

[0009] Preferably, the mounting base is provided with a limiting block, and the bracket is hinged with a limiting hook for hanging on the limiting block, and the end of the flexible connector away from the main body of the lifting platform is connected to the limiting hook.

[0010] Preferably, the mounting base is provided with a guide block for supporting the flexible connector.

[0011] Preferably, the lifting platform body is equipped with a camera.

[0012] Preferably, a mine chute dredging device includes a mobile device, a medicine delivery trolley, and a lifting platform as described above, wherein the lifting platform is mounted on the mobile device and the medicine delivery trolley is mounted on the lifting platform.

[0013] The beneficial effects of this utility model are as follows: the driving component drives the main body of the lifting platform to move horizontally on the sliding platform seat, so that the lifting platform can be further adjusted in a narrow space, ensuring that the lifting platform can accurately reach the predetermined area. The supporting legs support the horizontally moving lifting platform, increasing the stability of the lifting platform. At the same time, when the main body of the lifting platform moves, the linkage component will act on the supporting legs, causing the supporting legs to rotate, so that the supporting legs move synchronously with the main body of the lifting platform, which facilitates the unfolding and storage of the supporting legs.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1 Please see Figure 1 , Figure 3 and Figure 5A lifting platform includes a sliding platform base 1, with a lifting platform body 2 slidably mounted on the top of the sliding platform base 1; support legs are hinged to the side walls of the sliding platform base 1, and a linkage is provided between the support legs and the lifting platform body 2; when the lifting platform body 2 slides above the sliding platform base 1, the linkage will cause the support legs to rotate up and down (e.g., ...). Figure 3 As described above, the lifting platform body 2 moves to the left and the support leg rotates downward; the lifting platform body 2 moves to the right and the support leg rotates upward.

[0018] It should be noted that the linkage can be a flexible component, such as a steel wire rope, or it can be composed of a rack and pinion plate and a gear. The rack and pinion plate is installed at the bottom of the main body 2 of the lifting platform, and the gear is installed on the support leg. The gear meshes with the bottom of the rack and pinion plate. When the main body 2 of the lifting platform moves, it will move the rack and pinion plate, which will drive the gear to rotate the support leg.

[0019] Example 2 The following is a detailed explanation using one embodiment of the linkage as an example; Please see Figure 1 , Figure 3 and Figure 5 Mounting base 4 is installed on the side wall of sliding platform base 1. Support leg is hinged to mounting base 4. Linkage component refers to flexible connector 10 (such as steel wire rope). The two ends of flexible connector 10 are connected to the lifting platform body 2 and support leg respectively.

[0020] Working principle: The main body 2 of the lifting platform moves horizontally on the sliding platform base 1 (e.g., Figure 3 As shown, the lifting platform body 2 is driven to move to the left. At this time, the tension of the flexible connector 10 is reduced, which reduces the tension of the support leg. Under the action of gravity, the support leg rotates downward and contacts the ground to support the lifting platform body 2 after translation. When the lifting platform body 2 moves in the opposite direction to reset, the flexible connector 10 will be pulled and tightened by the lifting platform body 2, causing the support leg to rotate upward to a vertical state.

[0021] In this embodiment, as a further optimization, please refer to... Figure 3 A drive component 11 (such as a hydraulic cylinder) is installed on the sliding platform base 1. The moving end of the drive component 11 is connected to the lifting platform body 2. The lifting platform body 2 is moved by the drive component 11.

[0022] In this embodiment, as a further optimization, please refer to... Figure 1 , Figure 2 and Figure 3 The support leg includes a bracket 5 and a telescopic leg 6 mounted on the bracket 5 (referring to the hydraulic cylinder and the support plate, with the support plate mounted on the moving end of the hydraulic cylinder). The bracket 5 is hinged to the mounting base 4, and the overall length of the support leg can be adjusted according to requirements by extending and retracting the telescopic leg 6.

[0023] It should be noted that, as Figure 3 As shown, the support leg is located on the left side of the sliding platform base 1 to ensure its stability in supporting the lifting platform body 2.

[0024] In this embodiment, as a further optimization, please refer to... Figure 2 , Figure 3 and Figure 4 The bottom wall of the mounting base 4 is provided with a limit block 9, and a limit hook 7 is hinged on the bracket 5. The limit hook 7 is hung on the limit block 9 to lock the bracket 5 when it is rotated to face downwards, so that it will not move accidentally and to ensure the support of the bracket 5 and the telescopic leg 6 on the lifting platform body 2. The end of the flexible connector 10 away from the lifting platform body 2 is connected to the limit hook 7. When the lifting platform body 2 is reset, the flexible connector 10 will pull the limit hook 7 to rotate, so that the limit hook 7 does not contact the limit block 9, and release the lock on the bracket 5. Then the flexible connector 10 continues to pull the limit hook 7, so that it pulls the bracket 5 to move.

[0025] It should be noted that a spring is installed between the limit hook 7 and the bracket 5 to provide support for the limit hook 7 and ensure that the limit hook 7 will not automatically detach when it is hooked on the limit block 9.

[0026] In this embodiment, as a further optimization, please refer to... Figure 2 , Figure 3 and Figure 4 The mounting base 4 is provided with a guide block 8, which is used to support the flexible connector 10 and prevent friction between the flexible connector 10 and the mounting base 4.

[0027] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 3 A camera 3 is installed on the main body 2 of the lifting platform to observe the situation above the main body 2 of the lifting platform.

[0028] Example 3 Please see Figure 6 and Figure 7 A mine chute clearing device includes a mobile device 12 (such as a mobile vehicle), a delivery trolley 13, and a lifting platform. The lifting platform is mounted on the mobile device 12, and the delivery trolley 13 is placed on the lifting platform. The delivery trolley 13 is a remote-controlled vehicle with explosives mounted on top. After the mobile device 12 moves the lifting platform and the delivery trolley 13 to the area to be cleared, the lifting platform is raised. Then, the delivery trolley 13 places the explosives in the predetermined area. After completion, the lifting platform is reset, and the mobile device 12 moves away with the lifting platform and the delivery trolley. Then, the explosives are detonated to clear the mine chute.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
