Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, in particular to a hoisting tool for a sand box. Background Art

[0002] When carrying heavier goods, lifting tools are usually used. The gantry and the lifting tools are used together to carry heavier goods or products, thereby reducing labor. In the past, lifting tools hooked the goods or products and then lifted them. This method is indeed more convenient, but there are certain problems. When using the previous lifting tools, the hooks need to be hung on the four corners of the goods or products. They need to be hung every time they are lifted, and the hooks need to be taken out every time the goods or products are put down. This method is more troublesome and inconvenient to operate.

[0003] As for the sand box (a sand box is a mold used for casting), when lifting it, it is often lifted by hanging it with an existing hook, which is inconvenient. The sand box generally has a certain size, and the existing lifting tools are used for each lifting and each discharge process, which is repetitive, thereby wasting a lot of time for hanging and placing, affecting the processing of the sand box.

[0004] Therefore, in order to be able to adapt to the lifting and placing of sand boxes of different sizes without repeated operations, a hoisting tool for the sand box is specially proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a lifting tool for a sand box, which solves the problem that the prior lifting tools require repetitive operations of hooking and taking down when lifting and lowering goods or products, making the operation inconvenient and too cumbersome when dealing with a series of products with the same specifications and sizes.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lifting tool for a sand box, comprising a lifting structure and a connecting structure connected to the lifting structure, the lifting structure comprising a lifting frame, the front and rear inner walls of the lifting frame are provided with grooves, a movable column is movably installed in the groove, a sliding block is movably installed on the surface of the movable column, a hook is installed toward the inside of the sliding block, a load block is connected to the upper end of the hook, a connector is installed on the upper end surface of the load block, the surface of the connector is connected to the connecting structure, a connecting plate is installed in the middle of the inner wall of the lifting frame, an opening is provided on the surface of the connecting plate, the movable column passes through the opening, a groove is provided on the surface of the movable column, a protrusion is provided on the inner wall of the sliding block, the protrusion is inserted into the groove, and a gasket is provided on the surface of the hook.

[0007] Through the above technical solution, further, the connection structure includes a first steel wire connection rope, wherein the first steel wire connection rope is installed on a connecting body, and the ends of four groups of first steel wire connection ropes are fixedly connected to the first connecting body.

[0008] Furthermore, a second steel wire connecting rope is fixedly connected to the upper end of the first connecting body, and the end of the second steel wire connecting rope is divided into two outer branches through the second connecting body, and the surfaces of the two groups of outer branches are both provided with clamping rings.

[0009] As a preferred technical solution, a U-shaped body is movably installed on the upper end of the clamping ring, the U-shaped body is inserted into the clamping ring, a clamping bolt is installed on the end surface of the U-shaped body, and two outer support sleeves are arranged between the U-shaped body and the clamping ring.

[0010] Furthermore, the connection structure also includes a connection component connected to the gantry hook, and the connection component includes a sling connected to the gantry hook, and a hook ring is movably installed in the sling, and the surface of the hook ring is sleeved between the U-shaped body and the clamping ring.

[0011] As a preferred technical solution, a rubber pad is installed on the surface of the U-shaped body facing the clamping ring.

[0012] Compared with the prior art, the utility model provides a hoisting tool for a sand box, which has the following beneficial effects:

[0013] 1. For the same type of sand box specifications, it is only necessary to adjust the position of the movable column and the sliding block so that the hook corresponds to the hole opened on the surface of the sand box. At this time, due to the action of the load block, the hook is in an outwardly expanded state and will not be clamped with the hole on the surface of the sand box. At this time, through lifting, the tension of the load block wire connecting rope is lifted upward, which drives the hook to move upward, so that the hook is stuck in the opening on the surface of the sand box, thereby completing the clamping, and this state does not need to be adjusted to lift the next sand box, which is more convenient. Secondly, when the sand box is lowered, the weight of the load block itself is used to disengage the hook from the opening on the surface of the sand box. At this time, the user needs to pull the lifting frame. When encountering another sand box of different specifications and sizes, it is only necessary to adjust the position of the movable column and the sliding block. Then, through the above method, the lifting tool for the sand box is more convenient, and the lifting and placing operations of the sand box can be completed without too much repetitive operations, which is more convenient.
