Description

Technical Field

[0001] The utility model belongs to the field of lifting tools, and in particular relates to a lifting auxiliary tool suitable for large plates. Background Art

[0002] When lifting steel plates, lifting auxiliary tools are needed to connect the crane to the lifting machine through the lifting rope. Traditional lifting auxiliary tools usually use DD-B type steel plate hooks. When in use, four hooks are used in conjunction with the lifting rope to lift the steel plate. This type of hook only hooks the bottom of the steel plate and relies on the tension of the four hooks and the weight of the steel plate to achieve balance. If the plate shakes during the lifting process, it is very likely to cause the plate to fall off, thereby causing certain damage. Therefore, the reliability of current lifting auxiliary tools needs to be improved. Utility Model Content

[0003] (1) Technical problem to be solved: The hooks used in the prior art have the disadvantage of poor compatibility with steel plates and a high probability of plates falling off, so their reliability needs to be improved. The present utility model provides a relatively reliable lifting auxiliary tool suitable for large plates.

[0004] (2) The technical solutions adopted by this utility model are as follows:

[0005] A lifting auxiliary tool suitable for large plates includes a base plate, a side plate is provided on one side of the base plate, a bite plate is provided on the side plate, the middle part of the bite plate is hinged to the side plate through a pin shaft, one end of the bite plate is located above the base plate, and the other end of the bite plate is connected to a lifting chain. A through hole is provided on the top of the side plate, and the lifting chain is passed through the through hole.

[0006] A further technical solution is that the bite plate is provided with serrations on a side facing the base plate.

[0007] A further technical solution is that a plurality of pin connection holes are opened on the side plate, and the plurality of pin connection holes are distributed along the height direction.

[0008] A further technical solution is that the bite plates are divided into two, the two bite plates are connected by a connecting rod, and the connecting rod is connected to the hanging chain.

[0009] (3) Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0010] By arranging a side plate on one side of the base plate, the middle part of the bite plate and the side plate are hinged by a pin shaft, one end of the bite plate is located above the base plate, and the other end of the bite plate is connected to a lifting chain. When in use, the steel plate is placed between the bite plate and the base plate, and the lifting chain is pulled to make the bite plate close to the base plate, thereby biting the steel plate. Two lifting auxiliary tools recorded in the utility model are respectively installed on both sides of the steel plate. After the lifting chains in the two lifting auxiliary tools are connected to the lifting rope of the crane, the two lifting chains can be pulled at the same time so that the two lifting auxiliary tools can bite the steel plate for lifting. The heavier the steel plate, the greater the bite force. Compared with the existing technology, the lifting reliability of Jining using the lifting auxiliary tools in this solution is better, and the reliability of the steel plate falling off is greatly reduced.

[0013] Figure 3 It is a structural schematic diagram of the multiple pin shaft connecting holes described in the present invention. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-Figure 3 A lifting auxiliary tool suitable for large plates includes a base plate 1, a side plate 2 provided on one side of the base plate 1, a snap plate 3 provided on the side plate 2, the middle portion of the snap plate 3 being hinged to the side plate 2 via a pin 4, one end of the snap plate 3 being located above the base plate 1, the other end of the snap plate 3 being connected to a hanging chain 5, and a through hole 6 provided on the top of the side plate 2, through which the hanging chain 5 is inserted.

[0016] When in use, the number of lifting auxiliary tools is 2-4, which can be selected according to actual conditions. Taking four as an example, before lifting the steel plate, the four lifting auxiliary tools are installed in groups of two on both sides of the steel plate, so that the side of the steel plate is between the bite plate 3 and the bottom plate 1. The lifting chain 5 of each lifting auxiliary tool is connected to the lifting rope of the crane, and the four lifting chains 5 can be pulled at the same time. Since the lifting chain 5 is passed through the through hole 6 at the top of the side plate 2, the lifting chain 5 can also limit the side plate 2 while pulling the bite plate 3, thereby achieving the purpose of the bite plate 3 and the bottom plate 1 biting the bottom plate 1. The heavier the steel plate, the greater the bite force.

[0017] The bite plate 3 is provided with serrations 7 on one side facing the base plate 1 , which can increase the friction between the bite plate 3 and the steel plate, further play an anti-slip role, and further improve reliability.

[0018] The side plate 2 is provided with a plurality of pin connection holes 8, which are distributed along the height direction. When in use, the height at which the bite plate 3 is connected to the side plate 2 can be adjusted to adapt to steel plates of different thicknesses.

[0019] The two bite plates 3 are connected by a connecting rod 9, the connecting rod 9 is connected to the hanging chain 5, and the hanging chain 5 is connected to the connecting rod 9 through a hook.

[0020] The above are only preferred embodiments of the present invention.
