It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1 to 6, the box derrick welding auxiliary system comprises a box derrick unit and a welding auxiliary supporting device 20, wherein the box derrick unit comprises four side box boards 10, the side box boards 10 comprise steel plates 11, a plurality of H-shaped steel 12 are arranged on the inner sides of the steel plates 11, the length directions of the H-shaped steel 12 are parallel to the length directions of the steel plates 11, the H-shaped steel 12 comprises a first flange plate 121, a web 122 and a second flange plate 123 with the same structure as the first flange plate 121, and the second flange plate 123 is welded and connected with the steel plates 11; a first clamping groove 13 is arranged between adjacent H-shaped steel 12 in the side box plate 10; the welding auxiliary supporting device 20 comprises two supporting columns 21, a first flat tube 22 and a pull rope 23, wherein the first flat tube 22 is positioned between the two supporting columns 21, the supporting columns 21 comprise a second flat tube 211 which is mutually perpendicular to the first flat tube 22, the end part of the first flat tube 22 is welded with the middle part of the second flat tube 211, two ends of the second flat tube 211 are respectively provided with an electromagnet 212, and the end face of the second flat tube 211 is welded with the side wall of the electromagnet 212; the two ends of the second flat tube 211 are respectively provided with a first baffle 213 and a second baffle 214, a first mounting hole for the end part of the second flat tube 211 to enter and exit is formed in the center of the first baffle 213, the first mounting hole is rectangular, the hole wall of the first mounting hole is welded with the outer side wall of the second flat tube 211, a second mounting hole for the end part of the second flat tube 211 to enter and exit is formed in the center of the second baffle 214, the second mounting hole is rectangular, the hole wall of the second mounting hole is welded with the outer side wall of the second flat tube 211, the first baffle 213 is arranged between the second baffle 214 and the electromagnet 212, the first baffle 213 is tightly attached to the electromagnet 212, and a second clamping groove 215 matched with the edge part of the first flange 121 is formed between the first baffle 213 and the second baffle 214; the electromagnet 212 is positioned inside the first clamping groove 13, and the first baffle 213 is positioned inside the first clamping groove 13; a pull ring 221 is fixedly arranged in the middle of the first flat tube 22, and the tail end of the pull rope 23 is fixedly connected with the pull ring 221.
The H-shaped steel 12 is an economic section bar with an H-shaped section, and is also called a universal steel beam, a wide-edge I-steel or a parallel-flange I-steel. The H-section steel 12 is welded to the inner side of the steel plate 11 so that the bending strength of the side case plate 10 is remarkably improved. If the same quality steel plate material is welded on the inner side of the steel plate 11 to obtain a comparison side box plate, the bending strength of the side box plate 10 is 1.7-2.2 times of that of the comparison side box plate.
The first flat tube 22 and the second flat tube 211 are rectangular tubes, and have the same bending resistance and torsional strength, and are light in weight, so that they are widely used for manufacturing mechanical parts and engineering structures. Meanwhile, since the second flat tube 211 has a hollow structure, it is convenient for the cable connected to the electromagnet 212 to be routed inside the second flat tube 211.
In the manufacturing process of the box derrick unit, the first side box plate 10 is horizontally placed on the ground or a horizontal working table, then the second side box plate 10 is placed on one side of the first side box plate 10, and the second side box plate 10 can be supported by a wall surface perpendicular to the ground or a supporting table perpendicular to the horizontal working table, so that the second side box plate 10 is not easy to deviate. After full-welding is adopted between the second side box plate 10 and the first side box plate 10, the third side box plate 10 is placed on the other side of the first side box plate 10, and then a welding auxiliary supporting device 20 is placed between the third side box plate 10 and the second side box plate 10, as shown in fig. 7, wherein the electromagnet 212 is positioned in the first clamping groove 13, the first baffle 213 is positioned in the first clamping groove 13, and the two supporting columns 21 can move along the direction defined by the first clamping groove 13, namely, the two supporting columns 21 can move along the length direction of the side box plate 10; the edge of the first flange plate 121 is just clamped into the second clamping groove 215, and the welding auxiliary supporting device 20 is not offset when moving along the length direction of the side box plate 10 due to the cooperation between the edge of the first flange plate 121 and the second clamping groove 215, and is not offset between the third side box plate 10 and the second side box plate 10 due to the limitation of the first baffle 213 and the second baffle 214. When the welding operation is performed between the third side box board 10 and the second side box board 10, the supporting columns 21 are 1-1.5 meters away from the area to be welded, so that enough movable space is reserved for welding equipment and workers, and meanwhile, an area of 1-1.5 meters exists between the electromagnet 212 and the area to be welded, and the situation that the normal operation of the electromagnet 212 is influenced by high temperature generated when the area to be welded is welded when the electromagnet 212 is electrified can be avoided. In order to prevent the support column 21 from moving, the electromagnet 212 is energized, and since both the steel plate 11 and the H-section steel 12 can be absorbed by the electromagnet 212, the second flat tube 211, the first baffle 213 and the second baffle 214 can also be made of ferroalloy that can be absorbed by the electromagnet 212, and the support column 21 can not move any more under the absorption of the electromagnet 212; after welding 0.5-1 m between the third side box plate 10 and the second side box plate 10, the electromagnet 212 is powered off, the electromagnet 212 does not generate magnetic force at this time, the supporting column 21 is pulled by the pull rope 23 to move 0.5-1 m along the length direction of the side box plate 10, the pull rope 23 is stopped to be pulled, the electromagnet 212 is powered on, and the welding equipment is used for continuously welding the third side box plate 10 and the second side box plate 10 forwards for 0.5-1 m, so that the cycle is performed until the welding between the third side box plate 10 and the second side box plate 10 is completed. Similarly, when the fourth box board 10 is welded, the welding auxiliary supporting device 20 is placed between the fourth side box board 10 and the first side box board 10, and the above operation is repeated until the fourth box board 10 is welded, as shown in fig. 1.
When the third side box plate 10 and the fourth side box plate 10 are welded, due to the welding auxiliary supporting device 20, even if external force or dead weight acts on the two opposite side box plates 10, the two opposite side box plates 10 cannot deviate, so that the four side box plates 10 can be welded into a complete box type derrick unit. In the welding process, each time 0.5-1 meter is welded, the welding auxiliary supporting device 20 moves backwards by 0.5-1 meter, and the welding auxiliary supporting device 20 does not block the activities of welding equipment and welding staff, so that the welding equipment and the welding staff can freely weld in the box-type derrick unit, the operation is simple and convenient, and the time and the labor are saved; moreover, the welding auxiliary supporting device 20 can be moved by means of magnetic force generated by electrifying the electromagnet 212 and by means of de-electrifying the electromagnet 212, so that the fixing and separating operations of the welding auxiliary supporting device 20 become simple and convenient, and meanwhile, the welding auxiliary supporting device 20 can be recycled, and the construction cost is remarkably reduced. Wherein the spacing between adjacent webs 122 is equal. The distance between the adjacent webs 122 is x, the length of the electromagnet 212 is equal to the length of the first baffle 213, and the length of the electromagnet 212 is y, y=x, so that two ends of the electromagnet 212 can contact the webs 122, the adsorption area is further increased, and the fixing effect between the support column 21 and the side box board 10 is improved.
Further, as shown in fig. 8, a plurality of triangular reinforcing plates 30 are fixedly arranged between the adjacent side box plates 10, and the reinforcing plates 30 are all arranged inside the box-type derrick unit. The reinforcing plate 30 functions as a reinforcing rib, and can increase the strength of the joint surface between the adjacent side case plates 10.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
