Sampling device and sampling method for flame cutting of medium and heavy plates

Abstract

The invention discloses a medium-thick plate flame cutting sampling device and a sampling method thereof, belonging to sampling equipment. The device also includes a ground pit arranged on the bottom surface of the sampling station, a ground roller for supporting and rotating steel coils is arranged in the ground pit, and a pull belt steel wire rope is arranged on the ground at one side of the pit to be perpendicular to the axis of the ground roller; The pit above the drive motor of the roller is provided with guardrails and baffles, flame guns, pneumatic wrenches and pneumatic balers are hung around the guardrails, and the baffles are matched with the pits. The advantage is that the equipment required for sampling is simplified, the whole sampling process is convenient and fast, the work efficiency is improved, the labor intensity is reduced at the same time, and the production cost is saved; Eliminate potential safety hazards, and then the steel coil tail plate resets itself under the action of the ground roller, and the entire steel coil does not loosen, which provides convenience for subsequent re-bundling and packaging, and ensures smooth production.

Description

technical field [0001] The invention belongs to sampling equipment, in particular to a device for cutting and sampling medium-thick plates and strip coils, and also relates to a sampling method for the device. Background technique [0002] According to the requirements of the standard, after the steel plate and strip products in the form of steel coils are produced, samples need to be taken to test their components, and the samples should be taken within a range of 3 to 5 meters from the head. Due to the thickness and elasticity of medium-thick steel coils, sampling is very difficult and difficult to cut. The sampling device currently used is composed of a driving car, a saddle, a sampling trolley and a cutting device. When cutting, the crane lifts the sampling steel coil to the saddle, and the crane and the saddle cooperate to rotate the steel coil to the cutting position, and then uncoil, pry off the tail plate, cut, tighten the steel coil, pack the steel coil, and unload...

AI Technical Summary

Problems solved by technology

The existing defect is that the steel coil is hoisted to the saddle by the crane, and the saddle will inevitably shake when the steel coil weighing dozens of tons is uncoiled, causing the saddle to shift, and the gun head of the sampling trolley cannot be aimed at the cutting of the sample On the other hand, it is necessary to readjust the position of the gun head. The whole process is time-consuming, labor-intensive, and low-efficiency. At the same time, when the large sample (3m-long pipeline steel tail plate weighs about 500kg) is cut off, it is affected by the impact force and the sample falls. The sampling trolley is pushed out a few meters away in an instant, and the sampling trolley hits other equipment, causing damage, increasing production costs, and posing serious safety hazards
