Description

Length-adjustable lifting appliance

Technical Field

The utility model belongs to the technical field of lifting device, especially, relate to a length adjustable hoist.

Background

Currently, the current state of the art commonly used in the industry is such that:

when the die insert is disassembled and assembled, a T-shaped lifting appliance is usually used, the lifting appliance is fixedly connected with the insert through threads, then a lifting device is connected with the lifting appliance, and the insert is lifted and separated from the die cavity through the lifting device. The insert with large volume needs to be lifted by a plurality of lifting appliances at the same time, the insert is different in shape, the height of the place connected with the lifting appliances is different, in order to ensure that the insert can be lifted smoothly, the height of the point where each lifting appliance is connected with lifting equipment must be the same, the lifting appliances with fixed specifications cannot be well adapted to the inserts with different shapes, the insert is not easy to disassemble and assemble, and the efficiency is low.

In summary, the problems of the prior art are as follows: the existing hoisting device has high requirements on the hoisting tool, the hoisting tool with fixed specification can not be well adapted to the inserts with different shapes, the assembly and disassembly are not easy, and the efficiency is lower.

The difficulty in solving the technical problems is as follows: the insert is irregular in shape, the gravity center position of the insert is difficult to control, and the assembly and disassembly efficiency cannot be guaranteed.

Disclosure of Invention

Problem to prior art existence, the utility model provides a length adjustable hoist.

The utility model is realized in such a way that the lifting appliance with adjustable length is provided with a round pipe;

the lifting handle is welded at the tail end of the circular tube;

the screw rod is spirally arranged at the front end of the circular tube;

and the fixing nut is sleeved at the joint of the screw rod and the circular tube.

Further, both ends of the screw rod are provided with thread bodies with different lengths.

In summary, the advantages and positive effects of the invention are:

the length-adjustable lifting appliance ensures that the insert can be normally lifted, and can effectively avoid the damage of the inclined-pulling inclined lifting to the insert; convenient to use can improve work efficiency, saves T type hoist quantity, and convenient operation improves mould maintenance efficiency.

Drawings

Fig. 1 is a schematic structural diagram of a lifting appliance with adjustable length provided by the embodiment of the present invention.

In the figure: 1. a screw; 2. fixing a nut; 3. a circular tube; 4. a hanging handle.

Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

This adjustable length's hoist includes: both ends all screwed screw 1, hexagonal fixation nut 2 is provided with internal screw thread pipe 3, and the welding of pipe 3's end has lifting handle 4. The screw rod 1 is gone up the one end that the screw thread is few and is connected with inserting, and pipe 3 and screw rod 1 are through rotatory adjustment relative position for adjust overall length, and length adjustment is suitable back, restricts the position of pipe 3 and screw rod 1 with fixation nut 2, and the lift by crane handle 4 and lifting by crane equipment connection at last accomplishes the dismouting of inserting, separates the hoist and inserts through fixation nut 2 at last.

The working principle is as follows:

this length-adjustable's hoist makes the die insert focus can keep in central point and puts, inserts can not block in the die frame, makes things convenient for the dismouting, saves T type hoist quantity, and convenient operation improves mould maintenance efficiency. One end of a screw rod 1 is connected to the die insert through threads, the other end of the screw rod 1 is connected to the T-shaped sleeve through a nut 2, the height of the T-shaped lifting appliance is controlled by adjusting the thread access amount, the center of gravity of the die insert is kept at the central position, and a steel wire rope is hung on a lifting handle 4 for lifting.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.

Claims (2)

1. The length-adjustable lifting appliance is characterized by being provided with a circular tube;

the lifting handle is welded at the tail end of the circular tube;

the screw rod is spirally arranged at the front end of the circular tube;

and the fixing nut is sleeved at the joint of the screw rod and the circular tube.

2. The length-adjustable hanger according to claim 1, wherein both ends of the threaded rod are provided with threaded bodies of different lengths.
