Description

Technical Field

[0001] The utility model relates to the technical field of material transfer, in particular to a sling for raw material transfer. Background Art

[0002] After the casting coating is prepared, it is usually packaged in a packaging barrel. In order to facilitate operations such as transfer, the packaging barrel is usually provided with a pair of hanging ears at the upper end of the packaging barrel. During the transfer, the operator hooks the hook set on the crane on the hanging ears and then transfers it. However, during the operation, due to the stability of the crane movement and the quality of the packaging barrel, the hanging ears often break when the packaging barrel is transferred, resulting in waste of casting coating and even safety accidents. Utility Model Content

[0003] The utility model provides a sling for raw material transfer, which solves the shortcomings of the prior art, improves the safety during transfer and has strong practicability.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A sling for raw material transfer comprises a horizontal plate, two ends of the horizontal plate are respectively provided with a pair of guide holes, vertical rods are movably arranged in the guide holes, each pair of vertical rods on the same side are respectively provided with a limiting lower plate, the limiting lower plate is located on the lower side of the horizontal plate, the lower ends of each pair of vertical rods on the same side are respectively installed with mounting blocks, the lower ends of the mounting blocks are installed with support plates, the upper ends of each pair of vertical rods on the same side are respectively installed with T-blocks, the upper ends of the T-blocks are hinged with connecting plates, the upper ends of the connecting plates are hinged with convex plates, U-shaped rods are installed between the convex plates, the U-shaped rods are connected to a traveling crane by ropes, when the U-shaped rods are pulled upwards, the T-blocks are pulled inwards by the connecting plates, so that the support plates are passed through the lower ends of the packaging barrels, so that the support plates support the lower ends of the packaging barrels, thereby ensuring safety during transfer, and in this transfer method, due to the gravity of the packaging barrels during the transfer process, the support plates will stably support the packaging barrels.

[0006] Furthermore, a support plate is obliquely installed on the outer wall of the mounting block, and the lower end of the support plate extends obliquely outward. A roller is rotatably provided at the lower end of the support plate. The setting of the roller can improve the flexibility of the support plate moving inward when the support plate is pulled inward by the U-shaped rod.

[0007] Furthermore, the support plate is in a wedge-shaped structure, and its inner end is a small end, and the upper end of the support plate is an inclined surface, so that the support plate can be inserted into the lower side of the packaging barrel.

[0008] Furthermore, a limit pin is passed through the convex plate, and the lower end of the limit pin is arranged on the horizontal plate. The limit pin can limit the upward movement distance of the U-shaped rod, and through the limitation, it can prevent the mounting block from causing damage to the packaging barrel due to the inward force.

[0009] The lower plate is provided with an L-shaped rod, and the inner side of the horizontal section of the L-shaped rod is provided with a limit plate, and the inner side of the horizontal section of the L-shaped rod is provided with a sleeve. When the action plate is arranged to rotate, the lower end of the action plate will act on the horizontal plate, thereby causing the movable end rod to move upward, and the movement of the movable end rod will cause the movable vertical plate to move inward, and the horizontal section of another L-shaped rod will be passed through the plug sleeve through the movement, so that the hanging ear is constrained by the L-shaped rod and the plug sleeve, and in this way the packaging barrel is limited and constrained to avoid the problem of the packaging barrel falling during the transfer process.

[0010] Furthermore, the lower end of the action plate is in an arc-shaped structure to facilitate the rotation of the action plate.

[0011] The advantages of the above technical solution are:

[0012] When the packaging barrel is transferred, the utility model ensures the safety of the transfer by supporting and lifting the lower end of the packaging barrel. In addition, the stability of the packaging barrel is limited during the transfer, thereby further ensuring the safety. BRIEF DESCRIPTION OF THE DRAWINGS
