Description

Lifting appliance

Technical Field

The utility model relates to a lifting appliance, and belongs to the technical field of lifting appliances.

Background

When the annular and circular plate-shaped workpieces are hoisted, a plurality of problems such as skew, potential safety hazards and the like easily occur in the process of overturning the workpieces. Taking a flange disc workpiece as an example, the placing state of the flange disc workpiece when being stored is that the end face of the flange disc is kept horizontal with the ground, and when in production and processing, the flange disc needs to be hoisted so as to be convenient for a subsequent horizontal lathe to process. The existing hoisting tool can only hoist the workpiece according to the original placement state, can not realize the overturning of the workpiece by 90 degrees in the safe state in the hoisting process, easily generates deflection in the process of overturning the workpiece, has potential safety hazards and can not meet the use requirements.

In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.

Disclosure of Invention

Aiming at the defects, the utility model provides the lifting appliance which can improve the stability and the safety of workpieces in the lifting process; the workpiece can be quickly hoisted and turned over.

In order to solve the technical problems, the utility model adopts the following technical scheme: the lifting appliance comprises a stand column, wherein a cross rod is arranged at the end part of the stand column, one end, far away from the cross rod, of the stand column is connected with a lifting ring, and a sliding block is sleeved on the stand column;

support blocks are arranged at two ends of the cross rod, and the support blocks are provided with first clamping grooves; the sliding block is provided with a second clamping groove; the openings of the second clamping groove and the first clamping groove face opposite;

one side of the sliding block is connected with a clamping bolt in a threaded manner, and the clamping bolt penetrates through the sliding block to the second clamping groove to be abutted against the workpiece.

Further, the hanging ring is hinged with the upright post.

Further, the sliding block can slide up and down along the upright post.

Further, the stand column is perpendicular to the cross rod, and the stand column is arranged in the middle of the cross rod.

Further, the support block is far away from the cross bar one end and is provided with a lug, and a first clamping groove is formed between the lug and the cross bar.

Further, a plurality of the clamping bolts are provided.

After the technical scheme is adopted, compared with the prior art, the utility model has the following advantages:

according to the utility model, the three clamping grooves which are arranged in a triangle are arranged, and the workpiece is fixed through the clamping bolts, so that the stability of the workpiece in the hoisting process is ensured, and the safety is improved; meanwhile, when the workpiece is hoisted, the workpiece can be turned over by 90 degrees, so that the workpiece can be hoisted and turned over rapidly.

The utility model will now be described in detail with reference to the drawings and examples.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is a schematic view of a lifting workpiece in accordance with the present utility model;

in the drawing the view of the figure,

the device comprises a vertical column 1, a lifting ring 2, a cross rod 3, a supporting block 4, a protruding block 5, a first clamping groove 6, a sliding block 7, a second clamping groove 8 and a clamping bolt 9.

Detailed Description

For a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a lifting appliance, which comprises a stand column 1, wherein a cross rod 3 is fixed at one end of the stand column 1, and the cross rod 3 and the stand column 1 are fixed in a bolt connection or welding connection mode; the other end of the upright post 1 is connected with a hanging ring 2, and the hanging ring 2 is hinged with or welded with the upright post 1; the upright 1 is vertically arranged in the middle of the cross bar 3.

The lower parts of the two ends of the cross rod 3 are provided with supporting blocks 4, and the supporting blocks 4 are provided with first clamping grooves 6; the first clamping groove 6 is used for accommodating a workpiece; preferably, a bump 5 is arranged at one end of the supporting block 4 far away from the cross bar 3, and the bump 5 protrudes upwards; the first clamping groove 6 is formed between the protruding block 5 and the cross bar 3.

The upper portion of the upright column 1 is sleeved with a sliding block 7, a second clamping groove 8 for accommodating a workpiece is arranged on the sliding block 7, and the opening directions of the second clamping groove 8 and the opening directions of the first clamping groove 6 are opposite.

One side of the sliding block 7 is also in threaded connection with a plurality of clamping bolts 9, and the clamping bolts 9 penetrate through the sliding block 7 to the second clamping grooves 8 to be abutted against the workpiece so as to fix the workpiece.

The sliding block 7 can slide up and down along the upright post 1, so that the workpiece can be conveniently disassembled and assembled, and the workpiece lifting device can be suitable for lifting workpieces with different specifications.

The hoisting process of the utility model is as follows:

as shown in fig. 2, the lifting appliance is horizontally placed, a sliding block is slid, one side of a workpiece is clamped into a first clamping groove, then the sliding block is clamped into a second clamping groove, at the moment, the workpiece is clamped into the clamping groove, and then a clamping bolt is screwed to fix the workpiece; the lifting device is used for penetrating through the lifting ring to lift the workpiece, and in the lifting and transferring process, the workpiece is converted from the original state that the end face is parallel to the horizontal ground to the state that the end face of the workpiece is perpendicular to the horizontal line of the ground (the state shown in fig. 2), so that the workpiece can be quickly turned over.

The foregoing is illustrative of the best mode of carrying out the utility model, and is not presented in any detail as is known to those of ordinary skill in the art. The protection scope of the utility model is defined by the claims, and any equivalent transformation based on the technical teaching of the utility model is also within the protection scope of the utility model.
