Description

Coil trolley with rotatable steel coil

technical field

The utility model relates to the field of production of cold-rolled steel coils, in particular to a rotatable coil transporting trolley for steel coils.

Background technique

The production steps of the traditional cold-rolled steel coil are: firstly, lift the raw material pickled coil to the raw material saddle, untie the strap with strap shears, transport it to the uncoiler with a trolley, and roll it through the cold rolling mill. The finished product rolls are formed on the machine, and then transported to the finished product saddle by a trolley for bundling, and hoisted to the finished product area. In the process of loading and unloading, the rolling trolley is used to realize it. At present, the coil conveying trolleys are generally in the form of V-shaped brackets. During the unbundling process of steel coils, the steel coil head may be directly above or on the side of the steel coils, and loose coils are prone to appear after unbundling. In some cases, the head will fall down and injure personnel or equipment, and the same problem also exists in the bundling of steel coils. At present, the solution to this problem is generally in the form of a rotatable saddle roller used at the saddle position. When the steel coil is transported to the saddle roller, the coil delivery trolley puts the steel coil down, and the saddle roller rotates the steel coil to press the steel coil head. Unbundle again at the bottom of the steel coil. At this time, another problem has arisen. In order to improve production efficiency, multiple steel coil saddles will be installed, which can reduce the number of turnovers for lifting. However, only one saddle roller is generally installed, so that each steel coil must pass through the saddle roller before the strap can be untied, so that the coil transport trolley will carry the steel coil back and forth between the saddles, and the result is to reduce the Productivity.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the utility model mainly includes a vehicle frame 1 and a rotating wheel 11 installed on the vehicle frame 1, an elevating platform 2 above the vehicle frame 1, a rotating bracket 3 installed on the elevating platform 2 and The rotating roller 31 installed on the top of the rotating bracket 3, the hydraulic device 21 is provided between the lifting platform 2 and the vehicle frame 1, the rotating roller 31 is divided into a driving roller 31a and a driven roller 31b, and the driving roller 31a is Connected to the drive unit. The hydraulic device 21 can drive the lifting platform 2 to move up and down, so that the steel coil 4 carried on the rolling trolley reaches a predetermined height to realize coil winding and unloading, and the steel coil 4 is rotated by the rotating roller 31, when the steel coil 4 takes the lead Unbundling or bundling is carried out when the steel coil reaches the bottom, and the whole process can be completed on the coil transport trolley, which reduces the number of transfers and turnovers.

The trolley is provided with four rotating wheels 11, which are respectively installed on both sides of the vehicle frame 1, that is, two are respectively arranged at the front and rear ends of the vehicle frame 1, and a rotating shaft is connected between the two rotating wheels 11 at the same end. The rotating shaft is provided with a sprocket 12, and the vehicle frame 1 is provided with a reduction motor 13, and the reduction motor 13 drives the sprocket 12 to rotate through a chain 14. The rolling trolley generally runs on the rails, and it can move by itself by setting the geared motor 13, which reduces the labor intensity.

The cylinder body 21 a of the hydraulic device 21 is fixed on the vehicle frame 1 , and the cylinder head 21 b of the hydraulic device 21 is fixed below the lifting platform 2 . The cylinder body 21a of the hydraulic device 21 is preferably installed at the center of the vehicle frame 1, and the cylinder head 21b is also preferably installed at the center of the upgrading platform 2, so that the force on the whole rolling trolley is more uniform when it is raised and lowered. , running more smoothly.
