Box type derrick welding auxiliary system and use method thereof

Abstract

The invention relates to a box type derrick welding auxiliary system and a use method thereof. The system comprises a box type derrick unit and a welding auxiliary supporting device, wherein the box type derrick unit comprises four side box plates, each side box plate comprises a steel plate, the inner side of each steel plate is provided with multiple H-shaped steels, and a first clamping grooveis formed between every two adjacent H-shaped steels; and the welding auxiliary supporting device comprises two supporting columns, a first flat tube arranged between the two supporting columns and adraw cord. According to the box type derrick welding auxiliary system, the inner side of an existing steel plate is additionally provided with multiple H-shaped steels, the welding auxiliary supporting device is arranged between two opposite side box plates, so that the excursion cannot occur during welding of the third side box plate and fourth side box plate, and it is ensured that the four sidebox plates can be welded into the complete box type derrick unit. The welding auxiliary supporting device can be recycled and cannot cause obstacles to welding equipment and welding workers during the use, the operation is simple and convenient, and the time and labor are saved.

Description

technical field [0001] The invention relates to a box-type derrick welding auxiliary system and a using method thereof, belonging to the technical field of building installation. Background technique [0002] At present, in the construction process of most coal mines, non-coal mines and underground mining mines, a derrick needs to be erected. In order to reduce cost and weight, the derrick is usually a hollow structure. Because the length of the derrick is usually tens of meters, in the process of manufacture, it is usually processed into several derrick units, and then the derrick units are connected end to end to form the derrick. The derrick unit is usually welded into a box-shaped structure with four steel plates. Since the length of the steel plates is usually 6-12 meters and the width is 3-5 meters, the weight of the steel plates makes it difficult to adjust the position of the steel plates. When the steel plates are welded into a box-shaped derrick unit, the third an...

Problems solved by technology

Due to the existence of metal rods, it is very troublesome for welding equipment and welding workers to perform welding operations inside the box-type derrick unit, and the welding operation is time-consuming and labor-intensive; and, in order to facilitate wiring inside the box-type derrick in the follow-up, the There needs to be enough space inside the box-type derrick unit, that is to say, after the welding operation between the two opposite steel plates is completed, the welded metal rod needs to be cut off again. Changes cannot be reused, therefore, the amount of metal rods used is very large
