Technical Field

The invention belongs to the field of coil heat treatment, and particularly relates to a feeding and discharging trolley for a coil of a coil upender.

Background

In the production process of heat treatment of coils by a bell-type heating furnace, one or more coils are placed on a high-temperature material rack and are loaded into the furnace along with the high-temperature material rack for annealing heat treatment. The coil is horizontally placed on a high-temperature material rack in the furnace, but the coil is vertically transported by a forklift or a C-shaped hook in the transportation process, so that the coil needs to be turned over for 90 degrees once in the coil charging process. Therefore, when loading, the high-temperature material rack is laid flat by using the rolling machine, the coil conveyed by the forklift or the C-shaped hook is loaded into the high-temperature material rack by the loading and unloading trolley, then the rolling machine is turned up to stand the high-temperature material rack, and the high-temperature material rack and the coil are loaded into the furnace together; the process of unloading the coil from the hot rack is completely the reverse of the loading process.

Currently, the following problems exist in the process of loading or unloading coils into or out of a high temperature rack: 1) the external dimension of the coil is irregular, the external diameters and the central positions of different coils are different, each coil and the high-temperature material rack need to be centered during charging, charging is realized, and the heights of different coil brackets are different during discharging, so that the height of the bracket needs to be continuously adjusted to facilitate the coil to be smoothly discharged; 2) when the multiple rolls are unloaded, the rolls are easy to adhere to each other, and the trolley can slip when walking.

Furthermore, a limiting flange is arranged on one side, close to the pin rack, of the wheel and abuts against the side edge of the guide rail.

Further, the transmission mechanism adopts chain transmission and comprises a chain wheel and a chain.

Furthermore, the guide rail is made of steel.

The invention has the beneficial effects that:

hydraulic lifting and pin tooth transmission are adopted, the structure is simple, and the requirements on manufacturing and mounting precision are low; the speed reducing motor is positioned at the upper part of the tail end of the vehicle chassis and is far away from the coil upender, so that the maintenance is convenient; when the coil is charged and discharged, the height is adjusted through the lifting hydraulic cylinder to realize centering with the high-temperature material rack, so that the coil is convenient and quick; the walking is driven by the pin teeth, and if the coils are mutually adhered during multi-coil discharging, the wheels cannot slip, so that the coils are ensured to be smoothly discharged out of the high-temperature material rack.
