Description

Technical Field

[0001] The utility model relates to the technical field of coil drying racks, and particularly relates to a support-type multi-layer drying rack for use with transformer coils. Background Art

[0002] In the production and manufacturing process of transformers, insulation drying is one of the key processes, and its effect is the main factor affecting the dielectric loss and partial discharge of transformers. For decades, domestic and foreign researchers have been continuously exploring and improving the drying process methods of products, experiencing different stages such as vacuum drying, hot oil liquid-phase drying, hot air circulation drying, and variable voltage method drying processes. Currently, the drying process of transformers generally adopts hot air circulation and variable voltage method drying, and the insulation drying degree has achieved a relatively satisfactory effect. However, these drying process methods still have the deficiencies of long product drying cycle, large energy consumption, and relatively high product dielectric loss. At the same time, the transfer trays for placing coils occupy a large area, hold a small number of coils, waste space and energy, and delay the product delivery date. Summary of the Invention

[0003] An improvement is made to at least one defect of the prior art. The utility model provides a support-type multi-layer coil drying rack, which is simple to manufacture, has a low cost, and is convenient to operate.

[0004] To achieve the above object, the present invention adopts the following technical solution: A support-type multi-layer coil drying rack includes a fixed base with a rectangular hollow frame structure. More than 2 groups of fixed bases are arranged parallel to each other at intervals up and down. Four corners of the fixed base are surrounded by four groups of fixed rods to form a drying rack structure. Universal wheels are installed at the four corners of the lowermost fixed base. Sliding tracks are arranged on the parallel two sides of each layer of the fixed base. Drying trays are installed on the sliding tracks. More than 2 groups of cylindrical support rods are vertically arranged on the drying trays. A silicone rubber sleeve is sleeved on each group of support rods. A pull handle is arranged on the side surface of the drying tray perpendicular to the sliding track. Two legs connected by hinges are arranged on the bottom surface of the drying tray close to the handle.

[0005] A foldable inclined support is arranged between the legs and the drying tray.

[0006] The length of each group of legs is the same as the height of the corresponding drying tray bottom surface from the ground.

[0007] Anti-slip silicone pads are arranged at the bottom ends of the legs.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: The present utility model provides a support-type multi-layer coil drying rack. By setting a pull-out slideway, the drying tray can be conveniently pulled out, facilitating the picking and delivering of large-weight coils; by setting multi-layer drying trays, the number of coils for drying can be increased, while saving space and achieving the purpose of fully utilizing energy; by setting cylindrical support rods, the coils can be placed upright on the drying trays to increase the number of coils placed; by sleeving silicone rubber on the support rods, buffering is increased and the coils will not be bumped or scratched; by setting a pull handle, it is convenient for employees to operate and reduces labor intensity; by setting foldable legs, the drying trays can be effectively supported, with strong load-bearing capacity and space saving; by setting anti-slip silicone pads, it can easily bear the weight; by setting universal wheels, the transfer and movement of the drying rack can be facilitated.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] The structure of the present utility model is shown in the figure to Figure 7 , a support-type multi-layer coil drying rack, including universal wheels 1, which facilitate the transfer and movement of the entire drying rack; a fixed base 2 is arranged on the universal wheels 1. The fixed base 2 is a rectangular hollow frame, and there are multiple groups of fixed bases 2, which are arranged in parallel at intervals. The four corners are welded to the universal wheels 1 at the bottom, and welding fixing rods 3 are fixed above the four corners for welding the bases of each layer of the drying rack; sliding tracks 4 are arranged on both parallel sides of the fixed base 2 for the pulling and pushing of the drying trays 5, reducing the labor intensity; multiple cylindrical support rods 6 are arranged on the drying trays 5, enabling the coils to be erected and placed on the drying trays 5, increasing the number of coils placed; silicone rubber sleeves 7 are sleeved on the support rods 6 in a straight line, which can effectively increase the buffer and reduce the bumping and scratching of the coils. A pulling handle 8 is arranged on the side of the drying tray 5 perpendicular to the sliding track 4, which can facilitate the operation of employees and reduce the labor intensity; two legs 9 connected by hinges are arranged on the bottom surface of the drying tray 5 near the handle 8 for supporting the weight after the drying tray 5 is pulled out. The length of the legs 9 is the same as the height of the bottom surface of the drying tray 5 from the ground, and the length of the legs of each layer of drying tray is the same as the height of the bottom surface of the drying tray from the ground; a foldable inclined support 10 is arranged between the legs 9 and the drying tray 5, which can make the support firm and have a stronger load-bearing capacity, and at the same time, folding saves space; an anti-slip silicone pad 11 is arranged at the bottom end of the legs 9, which can easily bear the weight.

[0019] During the actual use of this device, the coils to be dried are transported to the constant temperature room. The drying tray 5 is pulled out through the handle 8, the legs 9 are opened, and the foldable inclined support 10 is adjusted to make the legs 9 stand stably on the ground. The coils are gently picked up and erected on the drying tray 5, and the sides of the coils are leaned against the support rods 6. After the drying tray 5 is filled with coils, the legs 9 are folded up, and the drying tray 5 is slowly pushed into the drying rack along the sliding track 4. By analogy, each layer of drying tray can place coils. Finally, the drying rack is moved to an appropriate position in the constant temperature room for coil drying.
