Description

Technical Field

[0001] The utility model relates to a lifting structure, in particular to a stable lifting structure of a cover plate. Background Art

[0002] In engineering projects, it is common to see some cable trench and pipeline trench covers. For the sake of overall beauty and safety, no lifting rings are reserved on them, but only two rectangular lifting holes are reserved. When lifting the cover, a lifting tool cut into the shape of an anchor is often used, and the lifting tool is inserted into the lifting hole for lifting. This lifting method is very likely to cause unhooking due to unbalanced force, which poses a great safety hazard and has low operating efficiency. Summary of the invention

[0003] The utility model aims to provide a stable lifting structure for a cover plate which has a scientific and reasonable structural design, is easy to operate, is not easy to unhook, is safe and reliable, has high lifting efficiency, and is easy to implement.

[0004] The utility model solves the technical problem through the following technical solutions:

[0005] A stable lifting structure for a cover plate includes an anchor-shaped sling, which is characterized by: further comprising a limit block and a cross brace, wherein the anchor-shaped sling is installed in the lifting hole of the cover plate, the limit block is clamped in the gap between the anchor-shaped sling and the lifting hole, and a cross brace is welded on the upper end surface of the limit block, and the cross brace is supported on the cover plate.

[0006] Moreover, the cover plate is a structure with lifting holes symmetrically arranged on the left and right.

[0007] Moreover, the width of the limit block is adapted to the width of the hoisting hole, and the length of the limit block is equal to the length of the hoisting hole minus the thickness of the anchor-shaped hanger.

[0008] Moreover, the anchor-shaped hanger is formed by a steel plate, and is composed of a hoisting ring portion, a vertical connection portion and a limiting anchor portion, and the hoisting ring portion is arranged on the upper part of the limiting anchor portion through the vertical connection portion.

[0009] The advantages and beneficial effects of the utility model are:

[0010] The stable lifting structure of the cover plate limits the position of the anchor-shaped sling in the lifting hole by setting the limit block, avoiding the cover plate unhooking problem caused by the anchor-shaped sling coming out of the lifting hole, improving the safety of the cover plate lifting, and effectively eliminating the potential safety hazard of the sling unhooking. Only one person is needed to operate the lifting operation easily, and the operation efficiency is greatly improved. At the same time, the lifting is stable, which also ensures the quality of the components and effectively eliminates the appearance damage of the components caused by unhooking.

[0017] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0018] A stable lifting structure for a cover plate includes an anchor-shaped sling 2, and its innovation lies in: it also includes a limit block 4 and a cross brace 3, the cover plate 1 is a structure with lifting holes 5 symmetrically arranged on the left and right, the anchor-shaped sling is installed in the lifting hole of the cover plate, the limit block is clamped in the gap between the anchor-shaped sling and the lifting hole, and a cross brace is welded on the upper end surface of the limit block, and the cross brace is supported on the cover plate.

[0019] The width of the limit block is adapted to the width of the lifting hole, and the length of the limit block is equal to the length of the lifting hole minus the thickness of the anchor hanger, so as to ensure that the limit block can stably squeeze the anchor hanger into the lifting hole.

[0020] The anchor-shaped sling is formed by processing a steel plate, and is composed of a hoisting ring portion 6, a vertical connection portion 7 and a limiting anchor portion 8. The hoisting ring portion is arranged on the upper part of the limiting anchor portion through the vertical connection portion.

[0021] The method of using the utility model is to make a pair of auxiliary metal plug plates that can be quickly installed based on the original lifting method by using the lifting holes of the cover plate. The plug plates can effectively prevent the anchor-shaped sling from rotating and unhooking due to unbalanced force. The plug plates are composed of a cross brace and a limit block: the limit block is inserted into the gap between the reserved lifting hole and the anchor-shaped sling to support the anchor-shaped sling and prevent the anchor-shaped sling from swinging left and right. The width of the limit block needs to be slightly smaller than the width of the anchor-shaped sling after being inserted into the lifting hole. The cross brace is welded to the limit block to prevent the limit block from falling into the lifting hole and play a fixing role.

[0022] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
