Description

Transformer core stacking and overturning platform transported by air cushion flat car

Technical Field

The utility model relates to the technical field of transformer overturning and processing equipment, in particular to a transformer core stacking and overturning platform transported by an air cushion flat car.

Background

A transformer iron core stacking and overturning platform is equipment for stacking and overturning iron cores in the process of producing transformers by transformer manufacturers. The iron core stacking and overturning platform is characterized in that the iron core is overturned by 90 degrees after being stacked on the main platform, and the iron core is vertically arranged on the side platform, like the large-scale hydraulic overturning platform disclosed by the Chinese patent CN201120560693.1, when the main platform and the side platform need to be combined by 90 degrees, the overturning oil cylinder jacks up the platform on one side to ascend until the main platform and the auxiliary platform reach 90 degrees.

In actual production, however, the width of the air cushion flat car bracket is fixed due to the fact that the thickness of the iron core is large. The existing iron core stacking turnover table can not directly place the iron core at the center of the air cushion flatcar bracket on the side table during turnover. The iron core lifting equipment can only be lifted off by a travelling crane and placed on an air cushion flat carriage bracket, and then the iron core is carried away by an air cushion platform. However, the crane needs to be equipped with a large-tonnage crane in a factory building when being lifted, and meanwhile, the hanging and dismantling of the rope are time-consuming and labor-consuming, and the safety risk is increased during overhead operation.

Detailed Description

The following provides a more detailed description of the embodiments and the operation of the present invention with reference to the accompanying drawings.

As shown in fig. 1-2, a transformer core stacking and overturning platform transported by an air cushion flat car comprises a main platform 1, a side platform 2, an overturning oil cylinder 3, a first hinge fixing seat 4 and a second hinge fixing seat 5, the main platform 1 is provided with a core column supporting table 6, the main platform 1 and the side platform 2 are respectively and correspondingly arranged on the first hinged fixed seat 4 and the second hinged fixed seat 5, the first hinged fixed seat 4 is hinged with the second hinged fixed seat 5 through a central hinge group 7, the overturning oil cylinder 3 is hinged at the bottom of the first hinged fixed seat 4 and the bottom of the second hinged fixed seat 5, be provided with position adjustable air cushion vehicle bracket 8 on side platform 2, just after articulated fixing base 5 of second drove side platform 2 upset 90, the downside of air cushion vehicle bracket 8 is less than the last side of main platform 1.

Specifically, one side of the air cushion vehicle bracket 8, which is far away from the main platform 1, is connected with the side platform 2 through an adjustable pull rod 10, and one side of the air cushion vehicle bracket 8, which is close to the main platform 1, is abutted against a limiting mechanism 9 arranged on the side platform 2.

Through the mutual cooperation of adjustable pull rod 10 and stop gear 9, can realize the regulation of hovercraft bracket 8 mounted position on side platform 2 to realize the regulation of hovercraft bracket 8 central point and put, so that it can be adapted to the transformer core S of different specifications.

Further, the limiting mechanism 9 comprises an installation plate 92 fixed on the side platform 2 through a fastening bolt 1, a limiting plate 93 is fixed on one side of the installation plate 92 away from the main platform 1, and the limiting plate 93 abuts against the hovercraft bracket 8; a plurality of adjusting bolts 94 are arranged on one side of the limiting plate 93 close to the hovercraft bracket 8, and the plurality of adjusting bolts 94 are distributed on the limiting plate 93 in at least two rows.

By adjusting the adjusting bolts 94, the left side surface of the hovercraft bracket 8 can be finely adjusted, so that the right side surface of the hovercraft bracket 8 is parallel to the left side surface of the transformer core S, and the center line of the hovercraft bracket 8 is ensured to coincide with the center line of the stacked transformer core S in the horizontal direction after being turned over.

Preferably, a reinforcing plate 95 is connected between the mounting plate 92 and the limiting plate 93 to reinforce the connection strength between the mounting plate 92 and the limiting plate 93.

In this example, an expansion sleeve type pin 11 is disposed at a position of the first hinge fixing seat 4 close to the central hinge group 7, a pin hole 12 is disposed on the second hinge fixing seat 5, and the expansion sleeve type pin 11 can be inserted into the pin hole 12 after the second hinge fixing seat 5 rotates by 90 °.

In the traditional technology, when the main platform and the side platform are combined and fixed for 90 degrees, the two sides of the main platform and the side platform 2 are respectively fixed by a pull rod, but the structure can influence the air cushion flat car to move out from the two sides of the platform. And this embodiment adopts bolt formula structure to carry out 90 combination to main platform 1, side platform 2 and fixes, has avoided traditional pull rod structure to influence the influence of air cushion flatcar. In addition, the large-scale iron core stacking overturning platform usually reaches 8-15 meters due to the large length of the platform surface, in order to bear the lateral component force of the iron core to the platform in the overturning process, a plurality of groups of hinged fixing seats are needed to be adopted for bolt fixing, due to the influences of machining precision, deformation and the like, great difficulty is brought to smooth insertion of the bolt, and in order to solve the problems, the bolt adopts an oil cylinder driven expansion sleeve type bolt.

The object of the present embodiment can be achieved by using the stem support base 6 having various height specifications so as to satisfy the condition that the center positions of the cores S have the same height in all the specifications. However, the number of the specifications of the stem supporting table 6 is increased, so that the cost is high; moreover, when the specification of the iron core S is changed, the core column supporting table 6 needs to be changed before stacking, so that the production efficiency is reduced; in addition, the core support table 6 is not easily stacked after being raised.

In addition, due to the characteristics of the air cushion flatcar, the edge of the side platform 2 and the workshop terrace foundation 13 need to be leveled and sealed, referring to fig. 3, an installation block 15 and a sealing body 16 are fixed on the workshop terrace foundation 13 through a connecting piece 14, a sealing gasket 17 is fixed on the sealing body 16 through a screw, and cushion blocks 18 are arranged at the bottoms of the installation block 15 and the sealing body 16.

Therefore, in the present embodiment, the main platform 1 and the rotation center (i.e., the central hinge group 7) of the side platform 2 are moved downward, after the side platform 2 rotates 90 degrees, the right edge of the air cushion vehicle bracket 8 on the side platform 2 is lower than the upper plane of the main platform 1, so that a downward movement space of the air cushion vehicle bracket 8 is left between the main platform 1 and the side platform 2, after the air cushion vehicle bracket 8 is moved downward, the center of the iron core can be aligned with the center of the bracket, and the turned state is as shown in fig. 4, so as to ensure that the stacked transformer iron core can be erected at the center of the bracket after being turned 90 degrees, and a sealing structure is adopted between the edge of the side platform 2 and the floor foundation of the workshop, so that the air cushion vehicle is adopted for transportation, and further, a traveling vehicle is not required to suspend the iron core away from a turnover device, thereby avoiding the defects of time and labor waste and high altitude operation safety risk.

The technical solution provided by the present invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts.
