Description

Technical Field

[0001] This utility model relates to the field of wall panel storage and transportation brackets, specifically a wall panel storage and transportation bracket for a large sulfuric acid storage tank. Background Technology

[0002] Sulfuric acid is an indispensable chemical solvent in large-scale smelters, and its demand is enormous. This high demand necessitates large sulfuric acid storage tanks, making them an essential facility in smelters. During the construction of these tanks, the curved steel plates for the tank walls need to be transported from the manufacturer to the site, and this transportation process presents another challenge.

[0003] Curved steel plates are a key component of sulfuric acid tanks. During the construction of these tanks, curved steel plates need to be continuously transported to the site for sequential hoisting and installation. Transporting the curved steel plates to the site requires securing them with transport brackets before trailer transport. Because of their large size, curved steel plates cannot be rolled up like steel coils for transport; they must be laid out, making securing them during transport a significant challenge. Therefore, developing a transport bracket for curved steel plates is essential to improving the safety and convenience of steel plate transportation.

[0004] To address the aforementioned issues, a storage and transportation support for the wall panels of a large sulfuric acid storage tank is proposed. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned problems and to provide a storage and transportation bracket for the wall panel of a large sulfuric acid storage tank.

[0006] The specific solution of this utility model is as follows: a large sulfuric acid storage tank wall panel storage and transportation bracket, comprising: a base, the base being a rectangular frame, the base having several crossbeams inside, short enclosure components symmetrically arranged on both sides of the middle of the base, the short enclosure components being baffles vertically arranged on the base; lifting lugs on both sides of the middle of the base; long enclosure components at both ends of the base, the long enclosure components comprising: long columns, two of the long columns being arranged in the width direction of the base; a support beam between the two long columns, the two ends of the support beam being fixedly connected to the upper part of the long columns; a locking mechanism at both ends of the base, the locking mechanism comprising: a drum, the two ends of the drum being rotatably connected to the base, a ratchet mechanism between the drum and the base, a pull cable on the drum, and a hook at the outer end of the pull cable.

[0007] Furthermore, a middle enclosure component is provided between the short enclosure component and the long enclosure component. The middle enclosure component includes a central column, and a limiting beam is provided in the middle of the central column. A limiting channel is formed between the limiting beam and the base.

[0008] Furthermore, the ratchet mechanism includes: a ratchet, which is fixedly sleeved on one end of the drum; and a pawl, which is rotatably connected to the base via a pin. A torsion spring is provided between the pawl and the base, and the torsion spring keeps the pawl engaged with the ratchet, thereby restricting the drum to rotate only in one direction, so as to realize the unidirectional winding and unwinding of the cable and prevent the cable from winding back uncontrollably.

[0009] Furthermore, the central column is provided with reinforcing ribs on both sides.

[0010] Furthermore, a support column is provided between the support beam and the base, and the support column is located in the middle of the support beam.

[0013] 1. This utility model has a simple structure, no complicated connections, and is easy to operate; it also has better overall stability and safety.

[0014] 2. The supporting beams of the long enclosure components allow the curved steel plates to maintain their curvature. No further curvature adjustment is required before reaching the construction site.

At the same time, it can be connected to a crane via lifting lugs for loading / unloading, which increases the overall flexibility of use, is reusable, saves construction costs, and improves the economic efficiency of construction.
