Description

A kind of positive extension is counter to mention electric block

Technical field

The utility model relates to a kind of crane hoisting equipment, more particularly to a kind of positive hang counter mentions electric block.

Background technique

Endless-chain electric hoist is also known as electric block, is a kind of light-duty crane hoisting equipment, is widely used in building, machine The object of the engineering fields such as tool, metallurgical mine, vehicle, ship slowly lifts.As shown in Figure 1, illustrating for existing electric block Cucurbit 1 is fixed on the eminence that object needs to be promoted during, the hook 2 on chain is hooked in lifting object by figure On.Heavy lift in place after if you need to continue up to be promoted, then need manually to have enough to meet the need cucurbit 1 toward on the suspension centre of higher height.

Electric block is also commonly used for attachment type raise scaffold field, and attachment type raise scaffold is skyscraper and superelevation Equipment used in layer construction is promoted in use or operational process or decline process is slowly to carry out, be often used electricity Cucurbit is moved as lifting device.Usual scaffold needs manual handling cucurbit 1 toward solid in high one layer of structure in lifting process It is fixed, after frame body promotion is fixed in place, needs to remove cucurbit 1, manually fix the floor that cucurbit 1 is transported to higher level, Another frame body is carried out after jack again to be promoted.Usually during decline, need manual handling cucurbit 1 toward in low one layer of structure Fixation needs to remove cucurbit 1, manually fixes the floor that cucurbit 1 is transported to lower level after frame body falls into place fixation, Another frame body decline is carried out after jack again.

The operation of above-mentioned cucurbit is not only laborious, and there is also great security risks, while cucurbit constantly dismounts, and gives equipment Also loss is brought.

Utility model content

The purpose of the utility model is to provide a kind of positive hang counter to mention electric block.

The purpose of this utility model is achieved through the following technical solutions:

The positive extension of the utility model is counter to mention electric block, including cucurbit ontology, lower draw-bar, upper hook and chain, the chain One end of item is fixed on the electric block ontology, the other end around the cucurbit ontology main drive wheel and lower draw-bar and upper The load-bearing guide wheel of hook, is finally fixed in the upper hook.

Positive extension provided by the embodiment of the utility model is counter it can be seen from above-mentioned technical solution provided by the utility model mentions Electric block does not need turnover cucurbit ontology during circularly enhancing or decline, it is only necessary to turnover hook, to reduce artificial Operation protects electric block, improves whole safety.The field for needing Integral synchronous group to hang in the realm of building construction, it is main It is used for the framework equipment that attachment type raise scaffold, pit shaft descending operation frame, creeping formwork etc. need Integral synchronous to be promoted.

Specific embodiment

The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail The content of description belongs to the prior art well known to professional and technical personnel in the field.

The positive extension of the utility model is counter to mention electric block, and preferable specific embodiment is:

Including cucurbit ontology, lower draw-bar, upper hook and chain, one end of the chain is fixed on the electric block ontology On, the other end is finally fixed at described around the main drive wheel of the cucurbit ontology and the load-bearing guide wheel of lower draw-bar and upper hook In upper hook.

The cucurbit ontology and lower draw-bar are fixed on lifting object, and the upper hook is fixed on the height that object needs to be promoted Place.

The cucurbit ontology is fixed on the top of lifting object, and the lower draw-bar is fixed on the lower part of lifting object.

The positive extension of the utility model is counter to mention electric block, and turnover cucurbit sheet is not needed during circularly enhancing or decline Body, it is only necessary to which turnover hook protects electric block, improve whole safety to reduce manual work.

The positive extension of the utility model is counter to mention cucurbit, has the advantages that

When lifting work, the cucurbit ontology is connect with by lifting object middle and lower part, the lower draw-bar with lifted by crane The connection of object lower part, the upper hook are fixed by component and force structure, and chain described in lifting process is in electric block Under the action of ontology main drive wheel, upper hook and the direct chain length of lower draw-bar are shunk, is risen to drive and be played hanging object, instead Can also make by rise hanging object decline.

It is fixed with force structure afterwards in place by lifting object, the lower draw-bar is detached from and is played hanging object, electric block Chain is put in overturning, by lower draw-bar from gravity, smoothly extends the chain length between upper hook and lower draw-bar.It is described in this way Hook of falling again connect with hanging object lower part, the upper hook can be followed toward hanging on higher force structure into next Ring.The utility model has the advantages of simple structure, easy to use, can reduce manual work, avoids the carrying of electric block ontology from colliding with, mentions High general safety performance, realizes automated job, suitable for the lifting of the light equipment repeatedly to work.

Specific embodiment:

The utility model includes electric block ontology 10, lower draw-bar 20, upper hook 30 and chain 40, chain as shown in Figure 2 On the fixed electric block ontology 10 of one section of 40, around 30 load-bearing of the main drive wheel of cucurbit ontology 10, lower draw-bar 20 and upper hook Guide wheel, the final other end are fixed on upper hook 30.

The electric block ontology 10 of the utility model mainly include driving motor, driving wheel, deceleration mechanism, load-bearing hook, Hook, steel shell etc..Lower draw-bar 20 includes hook and two load-bearing guide wheels, and the rigid part of connection.Upper hook 30 includes hook With a load-bearing guide wheel, and the rigid part of connection.

The utility model concrete operating principle is (as shown in Figures 2 and 3):

When lifting work, the cucurbit ontology 10 is connect with by lifting object middle and lower part, the lower draw-bar 20 and quilt The connection of hanging object lower part is played, the upper hook 30 is fixed by component and force structure, and chain 40 described in lifting process exists Under the action of 10 main drive wheel of electric block ontology, 40 length of chain between upper hook 30 and lower draw-bar 20 is shunk, thus band It is dynamic to be played hanging object rising, on the contrary it can also make to be played hanging object decline.

It is fixed with force structure afterwards in place by lifting object as shown in Figure 4 and Figure 5, the lower draw-bar 20 is detached from quilt Hanging object is played, chain 40 is put in the reversion of electric block 10, by lower draw-bar 20 from gravity, smoothly extends upper hook 30 and lower draw-bar 40 length of chain between 20.Lower draw-bar 20 is connect with hanging object lower part again in this way, the upper hook 30 past can be hung over more On high force structure, recycled into next promotion.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should Subject to the scope of protection of the claims.
