Description

Technical Field

[0001] The invention relates to the field of steel coil transportation, and in particular to a steel coil transportation system. Background Art

[0002] The steel coil transportation system is an indispensable part of the strip steel production system. The early steel coil transportation system consists of walking beams, fast chains and other equipment. The combination of the above equipment can realize the continuous transportation of steel coils from the coiler outlet to the corresponding target location in the warehouse area. This type of transportation system is gradually being replaced by a new type of steel coil transportation system due to the heavy weight of the equipment, high energy consumption, deep foundation and difficult maintenance.

[0003] In 2005, the pallet steel coil transportation solution began to be used in China for steel coil transportation. In the early stage, a double-layer structure was adopted, and the heavy-load rollers carrying steel coil pallets and the empty rollers conveying empty pallets were arranged vertically in the height direction. The disadvantages were that the equipment foundation was deep, the lower roller was difficult to inspect and repair, and the daily use and maintenance of the equipment were inconvenient.

[0004] In 2007, the pallet transport system evolved into a double-row arrangement, with the heavy-load rollers carrying steel coil pallets and the empty rollers conveying empty pallets arranged side by side in height. The equipment has a shallow foundation and is easy to use and maintain, but it occupies a large space.

[0005] In recent years, when some steel mills upgraded the traditional walking beam transport system, the double-layer pallet transport solution was basically no longer used because of its deep foundation and inconvenient use and maintenance. Figure 1 ) is a relatively good alternative. As shown in the figure, the double-row pallet transport system has two horizontally arranged transport rollers 1, and each transport roller is equipped with a steel coil saddle 2 for transporting steel coils 3. Since the two sets of transport rollers 1 are arranged side by side, the width of the equipment foundation is relatively large. For renovation projects, a large amount of foundation renovation is required, the construction period is long, and the overall investment of the project is relatively high.

[0006] It can be seen that when upgrading the transport chain equipment under the conditions of limited foundation space and short construction period, the original foundation should be used as much as possible, the equipment layout should be optimized, and the cost performance and construction period should be fully considered. In response to the above actual needs, a new steel coil transportation solution is proposed. This transportation solution occupies a narrow foundation width, has low construction difficulty, simple equipment, convenient maintenance, and obvious economy. Summary of the invention

[0007] The present invention provides a steel coil transportation system, the steel coil transportation system comprising:

[0008] A plurality of transport roller units, each of which is composed of a first heavy-load roller and a first light-load roller arranged horizontally, wherein the first heavy-load roller is arranged higher than the first light-load roller;

[0016] Balance beams are arranged at both ends of the first lifting platform near the guide wheel group, and the top of the balance beams is fixedly connected to the other end of the chain; wherein,

[0017] A transfer roller unit is arranged on the first lifting platform, and the transfer roller unit consists of a second heavy-load roller and a second light-load roller which are arranged horizontally and at different heights. The second heavy-load roller and the second light-load roller are distributed in the same manner as the first heavy-load roller and the first light-load roller.

[0018] Furthermore, each of the lifting type transverse roller vehicles comprises a frame, and a driving wheel group and a driven wheel group are respectively arranged on the front and rear sides of the bottom of the frame, and the driving wheel group and the driven wheel group are both arranged on a track perpendicular to the current transport roller unit;

[0021] The beneficial effects of the present invention are:

[0022] 1. Solved the problem of wide foundation width of existing steel coil transportation scheme. For example, the equipment layout width of double-row pallet steel coil transportation scheme requires 5.3 meters, while the equipment layout width of this scheme only requires 3.2 meters.

[0023] 2. The steel coil transportation solution is mainly composed of a transport roller unit, which can be combined as an integral module, easy to install and easy to repair and maintain.

[0024] 3. The width of the foundation pit of the traditional walking beam transportation scheme is basically between 3.5 meters and 4 meters.
