[0033] Example 1

[0034] See also Figure 1-Figure 2 This embodiment provides a scraper chain maintenance device to solve the problem of limited working space and low maintenance efficiency caused by the use of wire ropes and lifting chains to complete the existing scraper chain maintenance work.

[0035] In this embodiment, the scraper chain maintenance device includes a support tube 20 coaxially fixed to both sides of the transition plate 10, an adjusting rod 30 is rotatably inserted inside the support tube 20, and an adjusting disk 31 that is clamped to the inside of the transition plate 10 is fixedly connected to the middle part of the adjusting rod 30. An operating port 11 is opened on the transition plate 10, and screws 32 are fixedly connected to both ends of the adjusting rod 30. A slider 33 is screwed on the screw 32. The slider 33 is fixedly connected to a sleeve 34 mounted on the outside of the support tube 20, and a hook 36 is fixedly connected to the sleeve 34.

[0036] In this embodiment, by rotating the adjustment disk 31 at the operating port 11, the adjustment rod 30 and the screw rod 32 can be driven to rotate synchronously, thereby driving the two hooks 36 to move toward each other and allowing the hooks 36 to hook the rollers 41 of the scraper chain 40, thereby achieving appropriate margin of the scraper chain 40 between the two rollers 41, facilitating maintenance work, reducing the limitation of the working space, and having the advantage of easy operation.

[0037] It should be noted that the transition plate 10 is constructed as a whole into a hollow disc shape, and a circular installation space is defined inside the transition plate 10 for accommodating the adjustment plate 31. The two support tubes 20 are symmetrically arranged on both sides of the transition plate 10, and the two support tubes 20 are coaxially arranged with the transition plate 10. The operating port 11 is formed on the circumferential surface of the transition plate 10 and extends from the circumferential surface of the transition plate 10 toward the axial side. The operating port 11 is constructed as a whole into a fan shape. The operating port 11 is used to expose part of the circumferential surface of the adjustment plate 31, thereby providing an operating space for the operator to rotate the adjustment plate 31.

[0038] In addition, the adjusting disk 31 as a whole is coaxially arranged with the transition disk 10, and the adjusting rod 30 is symmetrically arranged on both sides of the adjusting disk 31. The adjusting rod 30 can be rotatably inserted into the corresponding support tube 20. As an example, the outer diameter of the adjusting rod 30 is equal to the inner diameter of the support tube 20, which can ensure the stability of the rotation of the adjusting rod 30 in the support tube 20. The screw 32 is integrally formed at the outer end of the adjusting rod 30, and the screw 32 and the adjusting rod 30 are coaxially arranged. The outer diameter of the screw 32 is smaller than the outer diameter of the adjusting rod 30. The two screws 32 are symmetrically arranged on both sides of the adjusting disk 31, and the two screws 32 have threads with opposite rotation directions, which are used to enable the rotation of the adjusting disk 31 to drive the two sliders 33 to move synchronously in opposite directions or reverse directions.

[0039] In addition, the slider 33 is integrally screwed onto the outside of the screw rod 32, and the outer diameter of the slider 33 is equal to the inner diameter of the support tube 20. A slide groove 21 extending along its axial direction is provided on the outer wall of the support tube 20, and the sleeve 34 is slidably sleeved on the outer wall of the support tube 20. The inner diameter of the sleeve 34 is equal to the outer diameter of the support tube 20. The sleeve 34 and the slider 33 maintain a one-to-one correspondence, and a connecting plate 35 is fixedly connected between the slider 33 and the sleeve 34, and the connecting plate 35 is integrally slidably engaged in the slide groove 21, and the hook 36 is fixedly connected to the outer wall of the sleeve 34. By utilizing the sliding engagement of the connecting plate 35 and the slide groove 21, the slider 33 is only allowed to slide along the axis of the support tube 20, and the two hooks 36 can be driven to move synchronously in opposite directions or reverse directions by rotating the adjusting disk 31.

[0040] When in use, first place the two hooks 36 on the two rollers 41 on the scraper chain 40, then rotate the adjusting disk 31 at the operating port 11 to make the two hooks 36 move toward each other until the hooks 36 hook the rollers 41 and make the scraper chain 40 between the two rollers 41 have an appropriate margin, at which time the chain plate or pin can be inspected and replaced.

[0041] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
