Description

Sand box capable of preventing lifting and slipping

Technical Field

The utility model relates to a casting technical field especially relates to a can prevent sand box that handling skidded.

Background

During the casting process, a flask is required to form the target part model. Before and after the target piece model is formed, the sand box is required to be lifted, moved or turned, and other working procedures are required, so that a lifting handle is required to be arranged on the outer surface of the sand box.

The sand box handle commonly used at present is bent into the ear type with the coarse reinforcement and directly welds on the sand box, when lifting by crane the operation to the sand box, generally can catch the sand box handle through the hoist cable pocket, perhaps catches on the sand box handle through the couple.

When the two operations are carried out, the surfaces of the handles are smooth, so that the sling is easy to fall off from the sand box handle when the sling is used, the life safety of workers is threatened, a large potential safety hazard exists, and sand mould scrapping can be caused when the sand box falls off; when the hook is used, the hook can also move along the curved surface of the handle, so that the sand box can swing back and forth in the moving process, the target piece model formed in the sand box can be easily damaged, and the hook is very inconvenient to use.

SUMMERY OF THE UTILITY MODEL

For the technical problem who exists among the solution background art, the utility model provides a can prevent sand box that handling skidded.

The utility model provides a sand box capable of preventing lifting and slipping, which comprises a sand box body, wherein two opposite side edges of the sand box body are provided with at least two lifting lugs;

the lifting lug is provided with two handle rod parts which are opposite in position and a connecting part for connecting one ends of the two handle rod parts, and the other ends of the two handle rod parts of the lifting lug are fixed with the sand box body;

the junction of two shank portions and connecting portion of lug still is fixed with spacing portion, and spacing portion is protruding to shank portion periphery.

Preferably, the limiting part is a circular ring-shaped or polygonal stop block.

Preferably, the shank portion and the connecting portion of the shackle are integrally formed.

Preferably, the shank portion and the connecting portion of the shackle are circular in cross-section.

The utility model discloses in, this sand box has following beneficial effect:

the lifting lug of the sand box is firm and reliable, two handle rod parts of the lifting lug can be used for lifting a sling, the connecting part between the handle rod parts can be used for lifting a lifting hook, the limiting part is arranged between the handle rod parts and the connecting part, the limiting part is protruded towards the periphery of the handle rod parts, the part protruded from the limiting part can block the sling from slipping towards the outer side of the lifting lug, and therefore the sand box can be prevented from falling off when being lifted, moved or overturned in various operations, and the sand box has good safety.

Two handle pole portions are connected to the connecting portion of this sand box lug, and connecting portion can supply the lifting hook application of force to lift by crane, because spacing position in the both ends of connecting portion, its bulge can hinder the lifting hook to handle pole portion removal to make the lifting hook only can be along a linear motion segment distance on connecting portion, make the sand box be difficult for the swing, at handling in-process not fragile model, it is very convenient to use.

Detailed Description

Referring to fig. 1-2, a sand box capable of preventing lifting and slipping according to an embodiment of the present invention includes a sand box body 1, and at least two lifting lugs 2 are disposed on two opposite sides of the sand box body 1. Each lifting lug 2 is provided with two opposite handle rod parts 21 and a connecting part 22 for connecting one ends of the two handle rod parts 21, the other ends of the two handle rod parts 21 of the lifting lug 2 and the sand box body 1 can be fixed in a welding mode, and ear holes of the welded lifting lug 2 are vertical to the upper surface and the lower surface of the sand box. A limiting part 23 is further fixed at the joint of the two shank parts 21 and the connecting part 22 of each lifting lug 2, the limiting part 23 can also be fixed on the lifting lug 2 by adopting a welding mode, and the limiting part 23 protrudes towards the periphery of the shank part 21.

In this embodiment, the shank portion 21 and the connecting portion 22 of the lifting lug 2 are integrally formed, the cross sections of the shank portion 21 and the connecting portion 22 of the lifting lug 2 are circular, and the top rod portion and the connecting portion 22 are formed by bending steel bars, so that the lifting lug 2 can have better strength.

The stopper portion 23 is preferably a circular or polygonal stopper, and the stopper portion 23 may have other shapes as long as the stopper portion 23 can surround the handle bar and protrude toward the outer periphery of the handle bar portion 21, thereby functioning as a stopper for a suspension cable or a hook.

According to the sand box of the embodiment, when the sand box is lifted, as shown in fig. 2, the handle rod part 21 of the lifting lug 2 can be held by the sling of the crane from the lower part of the lifting lug 2, the limiting part 23 is arranged between the handle rod part 21 and the connecting part 22, the limiting part 23 protrudes towards the periphery of the handle rod part 21, the protruding part of the limiting part 23 can block the sling to move towards the outer side of the lifting lug 2, the sling can be prevented from slipping and falling off, the sand box can be prevented from falling off during various operations such as lifting, moving or turning, the personal safety of workers can be ensured, and the model can be prevented from being damaged due to the falling of the sand box.

In addition, the sand box can also be lifted by hooking the lifting lug 2 through the lifting hook, the lifting hook can hook the connecting part 22 of the lifting lug 2, and the limiting parts 23 are positioned at the two ends of the connecting part 22, and the protruding parts of the limiting parts can prevent the lifting hook from moving to the handle rod part 21, so that the lifting hook can only move on the connecting part 22 for a small distance along a straight line and cannot move to the handle rod part 21, and great swing cannot be generated, so that the sand box cannot swing easily, and the model in the sand box cannot be damaged in the lifting process.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
