Abstract

The utility model provides an adjustable hook. The hook comprises a height adjustment structure. The height adjustment mechanism comprises a beam and a supporting plate. Each end of the height adjustment mechanism is respectively connected through a bolt. No less than one hole of the beam and the supporting plate matched with the bolt is a light hole. The bolt is provided with a positioning nut in a rotating mode. The supporting plate is fixedly provided with two tensile plates with long holes. The vertical length of the long holes is greater than the height of the beam. The beam passes through the long holes of the two tensile plates and is connected in a movable fit mode. A stand column is connected with the supporting plate. The adjustable hook has the advantages of adjusting precisely, placing hook plates of each hook in the same level, avoiding damage to a transformer in the hoisting process, and thus improving product quality. By adopting a novel base, the adjustable hook further has the advantages of using hook plates in different forms for different products and widening the using range.

Description

Adjustable suspension hook

Technical field

The utility model is a kind of adjustable suspension hook.

Background technology

In the production of shunt reactor, iron core column and coil need to be joined four independent suspension hooks with cross lifting beam and be lifted by crane.Because iron core cake of electric reactor and coil are of a great variety, therefore required suspension hook generally is that every kind of specification is joined a cover, causes suspension hook storage of a great variety and uses inconvenience.All there are manufacturing errors in four suspension hook length and plane, so four hook plates are not usually not at grade, and iron core cake and coil unbalance stress can cause distortion, even cause between the cake and cake of iron core, break away between the ectonexine of coil and damage, have product safety and operating personnel's potential safety hazard.For the low capacity reactor, the right alignment of iron core and coil etc. is required lower, therefore adopted behind the segmental hoisting the again mode of assembled formation.But for high-capacity reactor, height and the weight of iron core and coil are heavier, and high to the right alignment requirement of iron core cake simultaneously, the mode of therefore assembling again behind original segmental hoisting can not satisfy the higher requirements such as right alignment.Avoid contacting with the metal parts of suspension hook in order better to protect the iron core cake, installed the protection type insulcrete additional at driving surface, avoided the clashing and breaking of iron core cake glue-line and the pollution of metal powder.Although the technical personnel in the industry improves correlation technique, but still do not solve the coil hook plate on unified plane and problem that hook plate can not be general.

Summary of the invention

The purpose of this utility model is: disclose a kind of coil hook plate that can solve and be positioned at conplane problem, and further solve the adjustable suspension hook that same mechanism adapts to the voltage transformer assembling of different model.

The utility model comprises height adjustment mechanism, the column that connects successively and the base that is connected with column, described height adjustment mechanism comprises crossbeam and stay bearing plate, its each end respectively connects by a bolt, the hole that in crossbeam and the stay bearing plate at least one cooperates with bolt is unthreaded hole, is rotary with setscrew nut on the bolt; Be fixed with two on the stay bearing plate with the tension board of slotted hole, the longitudinal length of slotted hole is greater than the height of crossbeam, crossbeam pass on two tension boards slotted hole and with its running-fit; Column is connected with stay bearing plate.

During use, generally be that a plurality of the utility model use simultaneously, by the technical solution of the utility model, just can regulate respectively these suspension hooks, thereby with the hook plate adjustment on each suspension hook at grade, solve the damage problem that prevents in the hoisting process transformer part.

For the utility model, base portion is also done corresponding improvement, for example: can comprise with column being provided with suspension hook by dismantled and assembled the mode upper bed-plate that is connected and the movable hook plate that is connected with upper bed-plate on the movable hook plate.Like this, just can realize at suspension hook the replacing of hook plate, thereby make the lifting of the product that is applicable to different model.

In said structure, be provided with horizontal direction, dovetail furrow wide at the top and narrow at the bottom on the movable hook plate, the suspension hook consistent with its cross sectional shape is fixed in wherein, the modes such as suspension hook fixing can be with bolts, interference fit.

For making things convenient for column to lengthen or collection, described column can be set to folding structure.Its structure can be multiple known form, and also can be following form: described column is folding structure: column is by the connecting panel of upper pillar stand, lower pillar stand and connection, and the connecting panel two ends are connected with lower pillar stand with upper pillar stand by a pin respectively.Be to guarantee intensity and the convenient operation of column, the partial cross section that upper pillar stand or lower pillar stand are corresponding with connecting panel is aft-opening U-shaped structure, and the surface of end that connecting panel is positioned at the part of U-shaped structure is the arc surface take the pin that is close to this end as axle; The other parts of column are rhs-structure.After adopting folding structure, for strengthen pin and with its junction on lower pillar stand be subjected to force intensity, upper pillar stand and/or lower pillar stand both sides are equipped with strength plates by pin respectively.

Because the utility model in use, its column may touch the corresponding component of voltage transformer and the company of causing is electric, be preferably in its corresponding component and install insulating barrier additional, for example, column by strength layer and the insulating barrier that is arranged at least its front side or its all sides form, insulating barrier is fixed by screws on the strength layer.Can insulating barrier be set at other surface even whole outside face of column as required.

The beneficial effects of the utility model are: by height adjustment mechanism being set and fold mechanism is accurately regulated, make the hook plate of each suspension hook be positioned at same plane, and increased insulating barrier at column, thereby fully guarantee the lifting effect, prevent in the hoisting process damage to voltage transformer, thereby improve the quality of products.In addition, by the novel base of the utility model design, can also make the utility model use multi-form hook plate for different products, make its Applicable scope wider.
