Technical Field

The invention relates to a dry-type transformer casting mold gas trough plate demolding device and an operation method thereof.

Background

In the process of demoulding the iron sheet air duct plate, although the air duct plate is designed with a demoulding angle and brushed with a demoulding agent, demoulding is still difficult. If the pouring coil needs to be completely cooled in order to simply and easily demold, the efficiency is low in the actual production and manufacturing process, and the occupied resources are large. The demoulding method which is generally adopted at present is to fix the lower part of a cast coil by a clamp and use a crane to finish demoulding. The method has the advantages that the crane stroke is large, the crane and the pouring coil vibrate violently at the moment of demoulding, the danger coefficient is high, the noise is large, and the damage to equipment is large.

Disclosure of Invention

The invention improves the problems, namely the invention aims to solve the technical problems that the existing demoulding process by adopting a crane is large, the crane and a pouring coil vibrate violently at the moment of demoulding, the danger coefficient is high, the noise is large, and the damage to equipment is large.

The specific embodiment of the invention is as follows: dry-type transformer pouring mould gas tank board shedder, including a plurality of gas tank boards and the base that are used for shaping air flue, the top fixedly connected with roof of each gas tank board, wherein two tops have the trompil through roof fixed connection's gas tank board upper portion, it has the pole to run through in the trompil, it leaves the clearance to wear between pole and the roof, the base is the type of falling U and upper portion and strides between pole and the roof, base upper portion is fixed with the jack, can contact lifting and roof fixed connection's gas tank board with the roof when the flexible end extension of jack.

Further, the base includes vertical support column and is fixed in the horizontal backup pad at vertical support column top, the jack is fixed in on the horizontal backup pad.

Furthermore, the jack is a hydraulic jack.

Further, the top plate is connected with the air groove plate through bolts.

The invention also comprises an operation method of the dry-type transformer casting mold gas groove plate demoulding device, which comprises the following steps of:

(1) after the dry-type transformer is poured, the penetrating rod penetrates through an upper opening of the air trough plate, then the base penetrates through a space between the penetrating rod and the top plate, the lower part of the base is supported on a supporting platform surface or a ground supporting platform, and the upper part of the air trough plate is exposed under the base;

(2) hydraulic jack is placed above the base, the top plate is jacked up by the hydraulic jack, the top plate is fixedly connected with the gas groove plate, and the jack-up top plate can be lifted together with each gas groove plate fixedly connected with the top plate to realize gas groove plate demoulding.

Compared with the prior art, the invention has the following beneficial effects: the pre-demoulding device has a simple structure, pre-demoulding of the gas tank plate is realized by utilizing the ejector rods arranged and connected at the top of the gas tank plate and lifting the top plate through the base provided with the jack, and damage to a coil easily caused by adopting a crane demoulding mode is avoided.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, the air channel plate demolding device for a dry-type transformer casting mold comprises a plurality of air channel plates 10 used for forming air channels and a base, wherein a top plate 20 is fixedly connected to the top of each air channel plate, openings 110 are formed in the upper portions of the two air channel plates 10, the tops of the two air channel plates are fixedly connected to the top plate, penetrating rods 30 penetrate through the openings, gaps are reserved between the penetrating rods 30 and the top plate 20, the base 40 is in an inverted U shape, the upper portion of the base 40 spans between the penetrating rods 30 and the top plate 20, a jack 50 is fixed to the upper portion of the base 40, and when the telescopic end of the jack 50 extends, the jack can be in contact with the top plate 20 to lift the air channel plate 10 fixedly connected to.

In this embodiment, the base 40 includes a longitudinal support column and a transverse support plate 420 fixed on top of the longitudinal support column 410, and the jack 50 is fixed on the transverse support plate.

In this embodiment, the jack is a hydraulic jack, and the top plate is connected to the gas tank plate by bolts, or may be fixedly connected by welding or the like.

In operation, after the dry-type transformer is poured, the through rod passes through the upper opening 110 of the gas tank plate, then the base passes through the space between the through rod 30 and the top plate 20, the lower part of the base 40 is supported on a supporting platform such as a supporting table top or the ground, the upper part of the gas tank plate is exposed under the base, the hydraulic jack 50 is placed above the base 40, the top plate 20 is jacked up by the hydraulic jack 50, the top plate 20 is fixedly connected with the gas tank plate, the top plate can be connected with each gas tank plate together or connected with two gas tank plates one by one, and the gas tank plates 10 fixedly connected with the top plate can be lifted up by jacking the top plate by the jack. Because the hydraulic jack has small stroke, the demoulding hardly generates vibration, and the hydraulic jack is safe and reliable; due to the design of the demoulding inclination of the air channel plate, the demoulding with the maximum resistance can be completed in the effective stroke of the hydraulic jack. After the completion, the device is dismantled, and the air trough plate and the pouring coil are loosened, so that the air trough plate and the pouring coil can be easily pulled up.
