Description

Technical Field

[0001] The utility model relates to the technical field of transformer assembly frames, in particular to a lifting table of a transformer assembly frame. Background Art

[0002] In the production process of large transformers, there is a process of inserting upper yoke laminations into the "Mountain" - shaped iron core after the transformer is erected to form a closed - loop magnetic circuit. This process needs to be carried out on the yoke lamination platform, that is, placing the upper yoke of the transformer on the lamination feeding platform, and then taking the yoke laminations to insert.

[0003] During the process of inserting the upper yoke laminations of the transformer, because the materials stacked on the feeding platform of the transformer assembly frame are very heavy, it is easy to cause the risk of tilting or even falling of the feeding platform. Usually, support members are slidably installed at the bottom of the feeding platform to solve the problem of the feeding platform tilting. The support members are installed between the transformer body and the feeding platform. Slideways and sliders are installed at the bottom of the feeding platform for the sliding of the support members. However, the slideways and sliders are prone to deformation and damage under long - term stress, affecting the service life. Frequent replacement of parts even more affects the production and assembly of transformers.

[0004] Therefore, it is necessary to propose an improvement to overcome the defects of the prior art. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems in the prior art, and provide a lifting table of a transformer assembly frame to solve the problems of short service life and easy damage of the parts at the bottom of the feeding platform.

[0006] The technical solution of the utility model is as follows:

[0007] A lifting table of a transformer assembly frame includes a feeding platform. A transverse slideway is provided at the bottom of the feeding platform. A transverse sliding seat is slidably installed on the transverse slideway. A longitudinal slideway is provided on the transverse sliding seat. A longitudinal slider is slidably installed on the longitudinal slideway. A connecting seat is fixed on the longitudinal slider. A positioning pin is provided on the connecting seat. A longitudinal sliding seat is slidably installed on the positioning pin. A first support plate and a first fixing plate are provided on the longitudinal sliding seat. The positioning pin is slidably installed on the first fixing plate. The first support plate is arranged on the first fixing plate. The distance between the first support plate and the transverse sliding seat is less than the distance between the connecting seat and the first fixing plate.

[0008] Among them, a support member is installed on the longitudinal slide. When the support member is not stressed, in the natural state of the support member and the longitudinal slide, the distance between the first support plate and the transverse slide is less than the distance between the connecting seat and the first fixing plate. The longitudinal slide slides up and down along the positioning pin, driving the support member to slide up and down. By adjusting the length of the positioning pin, the distance between the first support plate and the transverse slide is controlled to be less than the distance between the connecting seat and the first fixing plate. When the lower end of the support member abuts against the transformer box, the longitudinal slide is stressed and slides upward along the positioning pin, and the first support plate slides to the bottom of the transverse slide and abuts against it, avoiding the stress on the longitudinal slideway and the longitudinal slider, prolonging the service life of the longitudinal slideway and the longitudinal slider under stress, and ensuring the production and assembly efficiency of the transformer.

[0009] As a preferred technical solution, a jack is provided at the lower end of the longitudinal slide for supporting the feeding platform.

[0010] As a preferred technical solution, a second support plate and a second fixing plate are provided on the longitudinal slide. The second support plate is fixed to the first fixing plate, the second fixing plate is fixed to the second support plate, and the jack is fixed to the second fixing plate.

[0011] Among them, during the transformer assembly operation, one end of the jack is fixed to the second fixing plate, and the other end supports the transformer body to prevent the feeding platform of the lifting platform of the transformer assembly rack from tilting.

[0012] As a preferred technical solution, a pin shaft hole is provided on the first fixing plate, the positioning pin is installed in the pin shaft hole, the positioning pin is in clearance fit with the pin shaft hole, and a fixing bolt is installed at the bottom of the positioning pin, and the fixing bolt is installed at the lower end of the first fixing plate.

[0013] Among them, when the longitudinal slide is stressed, the first fixing plate slides upward along the positioning pin.

[0014] As a preferred technical solution, a wear-resistant pad is provided at the upper end of the first support plate. When the first support plate abuts against the transverse slide, it is prone to wear under stress, and the wear-resistant pad prolongs the service life of the first support plate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] The lifting platform of the transformer assembly rack of the present utility model is equipped with a transverse slideway at the bottom of the feeding platform, a longitudinal slideway is installed on the transverse slideway, a longitudinal slider is installed on the longitudinal slideway, a connecting seat is installed on the longitudinal slider, a positioning pin is installed on the connecting seat, a longitudinal sliding seat is slidably installed on the positioning pin, the longitudinal sliding seat is provided with a first support plate and a first fixing plate, the positioning pin is slidably installed on the first fixing plate, and by setting the length of the positioning pin, the distance between the first support plate and the transverse sliding seat is controlled to be less than the distance between the connecting seat and the first fixing plate, so as to ensure that the longitudinal slideway and the longitudinal slider are not stressed when the support member is stressed, extend the service life of the components, reduce the frequency of frequent replacement of the components due to stress damage, and ensure the efficiency of transformer assembly.
