Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, and particularly relates to a steel plate lifting balance device on a traveling crane. Background Art

[0002] Most of the existing large-sized steel plates are unloaded by being lifted by a traveling crane. During unloading, steel plate clamps are often used to directly clamp both ends of the steel plate for hoisting.

[0003] This unloading method will cause the steel plate to bend when unloading relatively thin or small quantities of steel plates, and it is not easy to master the center of gravity of the steel plate, which easily causes the steel plate to tilt and slide. Bent steel plates often require a higher lifting height, increasing the danger. In severe cases, even steel plate slipping and injuring people accidents may occur, posing a large safety hazard. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a steel plate lifting balance device on a traveling crane, which solves the technical problems that most of the existing large-sized steel plates are unloaded by being lifted by a traveling crane, and steel plate clamps are often used to directly clamp both ends of the steel plate for hoisting during unloading, which easily causes the steel plate to tilt and slide, and there are large safety hazards.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0006] A steel plate lifting balance device on a traveling crane includes a traveling crane hook, an upper chain, and a balance beam. Among them, the upper chain is installed on the balance beam, the traveling crane hook is connected to the middle part of the upper chain, and two lower chains are provided below the balance beam. Steel plate clamps are installed at both ends of each lower chain, and a steel plate is clamped between the four steel plate clamps.

[0007] Preferably: The balance beam is a symmetric structure, and the main body is composed of two channel steels welded back to back. Two large lifting lugs and two small lifting lugs are welded on each side, and connection holes are provided on the large lifting lugs and the small lifting lugs.

[0008] Preferably: A lifting ring is installed on each large lifting lug, and the same lifting rings are installed on the two small lifting lugs located on the upper side.

[0009] Preferably: The two ends of the upper chain are respectively connected to the two large lifting lugs on the upper side of the balance beam through lifting rings, and the upper chain passes through the lifting rings on the two small lifting lugs located on the upper side.

[0010] Preferably: The middle parts of the two lower chains are respectively connected to the two lifting rings located on the lower side.

[0011] The utility model has the following beneficial effects:

[0012] 1. The lifting balance device of the present utility model changes the original lifting method that only clamps the steel plate at two places into clamping the steel plate at four places, which can effectively maintain the balance of the steel plate, reduce the lifting height, and improve the operation safety.

[0013] 2. The lifting balance device of the present utility model has a simple structure. When not in use, the lifting rings and chains can be removed and stored separately, or different chains can be replaced. The balance beam of the lifting balance device of the present utility model is of a symmetrical structure, which is convenient for use. Moreover, the upper chain can be directly connected to the large lifting ear without passing through the small lifting ear of the balance beam according to the on-site conditions, which is convenient for adjusting the lifting height.

[0017] The embodiment of the present application provides a steel plate lifting balance device on an overhead crane, which effectively solves the technical problem that most of the existing large-sized steel plates are unloaded by lifting with an overhead crane, and the steel plate is often directly clamped at both ends by a steel plate clamp during lifting, which is likely to cause the steel plate to tilt and slide, posing a great safety hazard. Embodiment

[0018] The general idea of the technical solution in the embodiment of the present application is as follows:

[0019] As Figure 1 shown, in view of the problems existing in the prior art, the present utility model provides a steel plate lifting balance device on an overhead crane, including an overhead crane hook 1, the overhead crane hook 1 is connected to an upper chain 2, the other end of the upper chain 2 is connected to one side of a balance beam 3, the other side of the balance beam 3 is connected to a lower chain 4, a steel plate clamp 5 is arranged on the lower chain 4, and the steel plate clamp 5 clamps both sides of a steel plate 6. The chain has the advantages of strong bearing capacity and convenient disassembly;

[0020] Further, the balance beam 3 is of a symmetric structure. Its main body is composed of two channel steels welded back to back. There are two large lifting lugs 31 and two small lifting lugs 32 on each side. Connecting holes 33 are provided on the large lifting lugs 31 and the small lifting lugs 32, and they are welded on both sides of the balance beam 3. There are four large lifting lugs 31, located at both ends of the balance beam 3. There are four small lifting lugs 32, arranged at the middle section of the balance beam 3, two on each side. The connecting holes 33 can all be connected to the lifting rings 7. Both ends of the upper chain 2 are connected to the overhead crane hook 1 and the large lifting lug 31 on one side of the balance beam 3 through the lifting rings 7. The upper chain 2 passes through the lifting rings 7 on the small lifting lugs 32 of the balance beam 3. One end of the lower chain 4 is connected to the large lifting lug 31 on the other side of the balance beam 3 through the lifting ring 7, and the other end is connected to the steel plate clamp 5. There are two sections of the upper chain 2 in total, forming a triangular structure with the balance beam 3. There are four sections of the lower chain 4 in total, two sections at each end of the balance beam 3, forming two triangular structures with the clamping lines of the steel plate 6. The steel plate 6 is clamped by the steel plate clamp 5 at four places, with a stable structure and a smooth and reliable hoisting process. In this embodiment, the distance between the steel plate 6 and the overhead crane is relatively short, which is suitable for the situation where the elevation difference between the hoisting starting point and the hoisting destination is large. Embodiment

[0021] Based on Embodiment 1, for a steel plate hoisting balance device on an overhead crane, the upper chain 2 is directly connected to the overhead crane hook 1 and the large lifting lug 31 on one side of the balance beam 3 through the lifting ring 7, without passing through the lifting rings 7 on the small lifting lugs 32 of the balance beam 3. This embodiment increases the distance between the steel plate 6 and the overhead crane, which is suitable for the situation where the elevation difference between the hoisting starting point and the hoisting destination is not large.
