Abstract
The utility model relates to a falling-preventive lifting bar for lifting moulds, which comprises a lifting bar body and an anti-loose retaining key. A mounting groove is processed at one end of the lifting bar body radially, the anti-loose retaining key is mounted in the mounting groove, the lower end of the anti-loose retaining key is provided with a threaded hole, a screw through hole and a screw cap counter hole are arranged below the mounting groove, a screw penetrates through the screw through hole from the lower side of the mounting groove and is connected with the threaded hole at the lower end of the anti-loose retaining key, and a screw cap of the screw is limited by the screw cap counter hole. A spring is sleeved on the screw, the lower end of the spring is abutted onto the bottom of the screw through hole, the upper end of the spring is abutted onto the lower end face of the anti-loose retaining key, the spring can support the anti-loose retaining key when the anti-loose retaining key is ejected upwards, and the upper end of the anti-loose retaining key can retract into the mounting groove under the action of pressure. The falling-preventive lifting bar is simple in structural design, convenient for processing, popularization and operation, quite high in safety, long in service life and applicable to various moulds, and falling of the lifting bar can be effectively avoided.
Description
Technical field
The utility model relates to a kind of mould structure.
Background technology
As everyone knows, in die production with in using, the mould transhipment is very frequent; Mould is all moving when using and transport always, and mold weight is more than 2 tons, and majority adopts hangers and the excellent lifting of lifting; Because the lifting rod self has constant weight; In case unstable with being connected of hanger, the generation safety misadventure that drops consequence is hardly imaginable, therefore the lifting rod is anti-lost quite important for safety in production.
And in the prior art, hanging rod only is to be through on the hanger, has the potential safety hazard that drops easily.
The utility model content
The purpose of the utility model is to provide a kind handling mould with anti-lost lifting rod to the deficiency that prior art exists.
The technical scheme of the utility model is following:
A kind of handling mould comprises lifting barred body and block key with anti-lost lifting rod.Radially process a mounting groove at an end of barred body, the shape of groove is processed as square or the anti-stop key of bar shaped rotates, and the anticreep block key is installed in mounting groove.There is tapped bore the lower end of said anticreep block key, has screw via hole and screw cap counterbore, a screw to pass the screw via hole from the below below the mounting groove and is connected with the lower end snail pit of anticreep block key, and the screw cap of screw is spacing by the screw cap counterbore.Be with spring on the screw, the spring lower end withstands on the bottom of screw via hole, and the upper end withstands on the lower surface of anticreep block key, and the anticreep block key is popped up, and spring plays the effect of supporting the anticreep block key, and anticreep block key upper end is the retractable mounting groove under pressure.
Further, weld a block in the outside of mounting groove, retaining is in the side of anticreep block key, can protect the effect of anticreep block key getting when hanging rod block, prevents come off the dangerous of distortion and increasing the service life of block key.
Said anticreep block key upper end towards that one side of barred body end for playing directional tagging in the inclined-plane.
The other end of said barred body radially is connected with one handle and just hangs rod with fetching.
The length of said handle is more than 1 times of excellent diameter of lifting, adopts welding manner to be connected with barred body.
The utility model is provided with compressible anticreep block key through the end at barred body, when assembling with hanger, is compressed, and after being seated, upsprings, and is stuck in the hanger side, make thus the lifting rod can not landing from hanger.This project organization is simple, is convenient to processing and popularization, and is easy to operate, can prevent to lift by crane rod effectively and drop, and safety is high, and period of service is long, is applicable to all moulds.
Description of drawings
Fig. 1 is the structural representation of this anti-lost lifting rod;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the upward view of Fig. 1;
Fig. 4 is the assembly relation scheme drawing of this anti-lost lifting rod and hanger.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, an end of this anti-lost lifting rod has rectangular handle 6, and the length of handle is more than 1 times of excellent main body 5 diameters of lifting, and anti-lost structure is to be made up of 3,1 screw 4 of 2,1 spring of 1 anticreep block key and 1 block 1.Radially process a mounting groove 51 at an end of barred body, the shape of groove is processed as square or the anti-stop key of bar shaped rotates, and anticreep block key 2 is installed in mounting groove.In the lower end of anticreep block key tapped bore 21 is arranged, have screw via hole and screw cap counterbore 52, screw 4 to pass the screw via hole from the below below the mounting groove and be connected with the lower end snail pit of anticreep block key 2, the screw cap of screw is spacing by the screw cap counterbore.Be with spring 3 on the screw, the spring lower end withstands on the bottom of screw via hole, and the upper end withstands on the lower surface of anticreep block key, and the anticreep block key is popped up, and spring plays the effect of supporting the anticreep block key, and anticreep block key upper end is the retractable mounting groove under pressure.Weld a block 1 in the outside of mounting groove, can protect the effect of anticreep block key getting when hanging rod block, on the other end of hanging rod, be provided with handle, block and handle adopt welding manner and lift by crane excellent main body and be connected.
Principle of work, referring to Fig. 4:
When mould need lift by crane; Hand arrest the excellent main body 5 of lifting with the termination aim at lifting special hole above the mould hanger 7 (generally big by 2 ~ 5mm) compared with hanging rod, slowly push away forward again, hanger lifting this moment special hole has contacted with anti-lost block key 2; Pushing away forward gently; Whole anti-lost block key gets in the hanger lifting eye fully, on the string steel rope pusher to terminal, anti-lost afterwards block key is upspring card always on hanger.The taking-up only with hand of lifting rod refers to that anti-lost block key is down pinned past hanger gently again to be pulled, and just can easily take out the lifting rod.
