Bridge steel plate hoisting device with adjustable hoisting gravity center

Abstract

The invention belongs to the field of hoisting equipment, particularly relates to a bridge steel plate hoisting device with an adjustable hoisting gravity center. The device aims to solve the problemsthat the gravity center of a bridge steel plate hoisting device is inconvenient to adjust when bridge steel plates with different sizes are hoisted, a protection mechanism is not arranged, and safetyaccidents easily occur when faults occur. The hoisting device comprises a hoisting machine and a hoisting ring, a noose is arranged on the hoisting machine, the noose and the hoisting ring are fixedly installed, two first steel cables which are symmetrically arranged are fixedly installed on the hoisting ring, a same installation plate is fixedly installed at the bottoms of the two first steel cables, an adjusting block is fixedly installed at the bottom of the installation plate, and the adjusting block is hollow. According to the bridge steel plate hoisting device, bridge steel plates of different sizes can be hoisted at different gravity centers, the hoisting stability of the bridge steel plates is high, the application range is wide, the bridge steel plates in the hoisting process canbe protected, and the safety coefficient of hoisting the bridge steel plates is increased.

Description

technical field [0001] The invention belongs to the field of hoisting equipment and relates to a bridge steel plate hoisting device with an adjustable hoisting center of gravity. Background technique [0002] Bridge steel plate is a thick steel plate specially used for manufacturing bridge structural parts, and is made of carbon steel and low alloy steel for bridge construction. Bridge steel plates are mainly used to build railway bridges, highway bridges, sea-crossing bridges, etc. It is required to have high strength, toughness and withstand the load and impact of rolling stock, as well as good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. [0003] At present, in the production of enterprises, the lifting and transshipment of bridge steel plates are often involved. Due to the heavy weight of the bridge steel plate, the steel wire rope is passed through the bottom of the steel plate during hoisting, and then connected with the...
