Medium-thick plate flame cutting sampling device and sampling method thereof

Abstract

The invention discloses a medium-thick plate flame cutting sampling device and a sampling method thereof, belonging to the sampling equipment. The medium-thick plate flame cutting sampling device also comprises a pit formed in the bottom surface of a sampling station, wherein a ground roll for supporting and rotating a steel coil is arranged in the pit, a pulling steel rope is arranged on the ground at one side of the pit and is perpendicular to the axis of the ground roll, a guardrail and a baffle are arranged in the pit above a driving motor of the ground roll; a flamer, an air wrench and a pneumatic packer are suspended at the periphery of the guardrail, and the baffle is matched with the pit. The medium-thick plate flame cutting sampling device has the advantages of simplifying equipment required by sampling, having convenience and rapidness in the whole sampling process, improving the working efficiency, reducing the labor intensity and saving the production cost; the whole tail plate is pulled by the pulling steel rope after being cut, the tail plate can incline to the ground slowly, the potential safety hazard is eliminated, then the tail plate of the steel coil can automatically restore under the action of the ground roll, and the whole steel coil cannot be loosened, thereby bringing convenience to the follow-up rebinding and ensuring smooth process of the 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
