Description

Technical Field

[0001] The present application relates to the technical field of road material production, and in particular to a lifting device for transferring cover plates without lifting rings. Background Art

[0002] Side ditches are longitudinal artificial ditches installed outside the cut shoulder and the footing of low-fill roadbeds to collect surface water. Side ditches play a crucial role in pavement structure, connecting the roadbed slope with the roadside, acting as a "bridge" between the two. Side ditches require covering with slabs, which significantly enhance the overall aesthetics of roads and sidewalks and facilitate pedestrian and vehicle traffic. Currently, side ditches are no longer equipped with steel lifting rings, and conventional lifting methods are no longer suitable for covers without lifting rings. Utility Model Content

[0003] The present application provides a lifting device for transferring cover plates without lifting rings, which solves the problem that cover plates without lifting rings are not suitable for crane lifting at this stage.

[0004] The technical solution of this application is as follows:

[0005] A lifting device for transferring cover plates without lifting rings, comprising:

[0006] A vertical plate, wherein the vertical plate is parallel to the thickness direction of the cover plate;

[0007] An upper splint, the upper splint being L-shaped, with its short side fixedly connected to the vertical plate and its long side extending toward the upper surface of the cover plate;

[0008] A lower splint, the lower splint is L-shaped, with its short side fixedly connected to the vertical plate below the upper splint, and its long side extending toward the lower surface of the cover plate;

[0009] an upper extension plate, the upper extension plate being L-shaped, with a long side thereof being anchored to a long side of the upper clamping plate at a first position;

[0010] The lower extension plate is linear and is anchored to the long side of the lower clamping plate at the second position and the third position. The second position and the third position correspond to the two ends of the first position after being translated upward.

[0011] Furthermore, rubber gaskets are provided on the lower surface of the upper clamping plate, the lower surface of the upper extension plate, the upper surface of the lower clamping plate, and the upper surface of the lower extension plate.

[0012] Furthermore, the surfaces of the vertical plate, the upper clamping plate, the lower clamping plate, the upper extension plate and the lower extension plate are all provided with a plurality of bolt holes for anchoring.

[0013] Furthermore, the end of the long side of the lower clamping plate is cut downward to form a release angle.

[0014] Furthermore, one end of the lower extension plate facing the lower surface of the cover plate is cut downward to form a release angle.

[0015] Due to the adoption of the above technical solution, the beneficial effects of this application are as follows:

[0016] 1. The present application forms a space capable of stably clamping the cover plate through the upper and lower clamping plates, and further extends the upper and lower surfaces of the cover plate through the upper extension plates and the lower extension plates. When two or more sets of lifting devices are used at the same time, the cover plate's anti-overturning ability during the lifting process can be significantly improved, and this process does not require the cover plate to have a lifting ring structure.

[0017] 2. In this application, the second position and the third position are located at both ends of the first position after translation, which can make up for the support blind spot of the cover plate. At the same time, since the second position and the third position are at the bottom, the distance between them is larger, so they can better play a supporting role.

[0018] 3. As a preferred embodiment of the present application, the various components in the present application are fixedly connected by detachable bolts and bolt holes, and different installation lengths can be adjusted according to different plate sizes to achieve multi-scenario applications of a sling, and the lifting of special-shaped cover plates can be achieved by adjusting one of the slings separately.

[0024] Based on the background technology, the present application provides a lifting device for transferring a cover plate A without a lifting ring, comprising:

[0025] A vertical plate 1, wherein the vertical plate 1 is parallel to the thickness direction of the cover plate;

[0026] An upper splint 2, the upper splint 2 being L-shaped, with its short side fixedly connected to the vertical plate 1 and its long side extending toward the upper surface of the cover plate A;

[0027] The lower splint 3 is L-shaped, with its short side fixedly connected to the vertical plate 1 below the upper splint 2 and its long side extending toward the lower surface of the cover plate A;

[0028] An upper extension plate 4 , the upper extension plate 4 is L-shaped, and its long side is anchored to the long side of the upper clamping plate 2 at a first position 6;

[0029] The lower extension plate 5 is linear and is anchored to the long side of the lower clamping plate 3 at the second position 7 and the third position 8. The second position 7 and the third position 8 correspond to the two ends of the first position 6 after being translated upward.

[0030] As attached Figure 1 and attached Figure 2 As shown, in this embodiment, the vertical plate 1, the upper clamping plate 2, the lower clamping plate 3, the upper extension plate 4, and the lower extension plate 5 all utilize their thickness to clamp the cover plate A. In this embodiment, the upper clamping plate 2 and the lower clamping plate 3 are fixed to the vertical plate 1 by two bolts. In different embodiments, the upper clamping plate 2 and the lower clamping plate 3 can also be fixed in different positions to accommodate different thicknesses of the cover plate A.

[0031] In this embodiment, the upper extension plate 4 is slightly shorter than the lower extension plate 5 to enhance the support provided by the bottom and stabilize the cover A during transfer. The upper clamping plate 2 and upper extension plate 4 are anchored at a first position 6, while the lower clamping plate 3 and lower extension plate 5 are anchored at a second position 7 and a third position 8, respectively. After translation, the second and third positions 7 and 8 are positioned at opposite ends of the first position 6. This increases the stability of the cover A during support and prevents it from tipping over.

[0032] In different embodiments, the cover plate A with a wider and longer size can be clamped by further adding upper extension plates 4 and lower extension plates 5 .

[0033] As a preferred embodiment of the present application, rubber gaskets 11 are provided on the lower surface of the upper clamping plate 2, the lower surface of the upper extension plate 4, the upper surface of the lower clamping plate 3, and the upper surface of the lower extension plate 5. The rubber gaskets 11 can reduce the pressure at the application point and prevent the cover plate A from being crushed due to excessive local stress.

[0034] As a preferred embodiment of the present application, the surfaces of the vertical plate 1, upper clamping plate 2, lower clamping plate 3, upper extension plate 4, and lower extension plate 5 are each provided with a plurality of bolt holes 9 for anchoring. Multiple anchoring positions enable the use of a single tool in multiple scenarios, helping to adapt to the size and shape of the cover plate A.

[0035] As a preferred embodiment of the present application, the end of the long side of the lower clamping plate 3 is cut downward to form a release angle 10. The release angle 10 is an angle cut to avoid material processing during machining. In the present application, the release angle 10 can avoid stress concentration and increase the service life of the sling.

[0036] As a preferred embodiment of the present application, one end of the lower extension plate 5 facing the lower surface of the cover plate A is cut downward to form a release angle 10.

[0037] In specific applications, the sling is fixedly mounted on a crane, and the cover is raised and lowered by operating the crane. The crane is installed via ropes at the front ends of the two sets of upper extension plates 4 and the bolt holes 9 of the vertical plate 1 to achieve the sling's lifting. In other words, the bolt holes 9 also serve as entry points for the ropes. To prevent the cover from tipping over during the lifting process, the lengths of the left and right ropes can be controlled to tilt the sling. If necessary, ropes can also be installed axially to prevent the cover from slipping. However, in most scenarios, the lifting distance of the sling will not be too long, and the transfer function can be achieved without ropes.

[0038] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0039] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
