Hoisting equipment with overload protection function for steel coil production

Abstract

The invention relates to the technical field of steel coils, in particular to steel coil production hoisting equipment with an overload protection function, which comprises a steel coil, a controller, an alarm and two pressure sensors, the controller needs to be externally connected with a power supply through a wire, and the alarm and the pressure sensors are electrically connected with the controller through wires; a traction device is arranged on one side of the U-shaped bottom plate, and a controller and an alarm are fixed to one side of the U-shaped bottom plate. The universal wheels are fixed on the lower side of the U-shaped bottom plate; the lifting plate is arranged on the upper side of the U-shaped bottom plate, and the two pressure sensors are fixed to the lower side of the lifting plate. Through the arrangement of the controller, the alarm, the pressure sensor, the U-shaped bottom plate, the universal wheels, the lifting plate, the sliding blocks, the sliding holes, the connecting bases, the lifting rods, the supporting bases and the guide columns, the lifting device has the functions of automatic lifting, overload protection, synchronous automatic adjustment, universality, dual protection, falling prevention and the like.

Description

technical field [0001] The invention relates to the technical field of steel coils, in particular to a hoisting device for steel coil production with an overload protection function. Background technique [0002] Steel coil, also known as coil steel. The steel is hot-pressed and cold-pressed into rolls. In order to facilitate storage and transportation, and facilitate various processing (such as processing into steel plates, steel strips, etc.), formed coils are mainly hot-rolled coils and cold-rolled coils. Hot rolled coil is a processed product before billet recrystallization. Cold rolled coil is the subsequent processing of hot rolled coil. The difference between cold-rolled steel and hot-rolled steel is not in the smelting process, but in the rolling temperature, or the termination temperature of rolling. The finish rolling temperature lower than the recrystallization temperature of the steel becomes cold rolled steel. Hot-rolled steel is easy to roll and has high r...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the steel coil hoisting equipment in the prior art has no overload protection function, so that the steel coil may fall due to overload during use, which may cause personal injury and cause Due to the shortcomings of causing economic damage, low safety, and no general function, it is impossible to lift steel coils of different specifications, and propose a lifting equipment for steel coil production with overload protection function
