Description

Technical Field

[0001] The utility model belongs to the technical field of coke oven brick gas channel positioning tools, in particular to a portable coke oven brick gas channel positioning tool. Background Art

[0002] The coke oven gas duct pipe brick is directly connected to the coke oven gas downspout, and is the channel for the coke oven gas to enter the coke oven body for combustion and provide heat energy. The accuracy of the center distance position of the gas pipe brick channel has a great impact on the fire adjustment, temperature control and iron maintenance in the production process after the coke oven is put into production. According to relevant specifications, the spacing of the center line of the brick gas duct and the spacing with the longitudinal center line of the coke oven are allowed to have an error of ±3mm. If the error is too large, it will directly affect the normal production of the coke oven. The traditional control method for laying gas pipe bricks is: the first layer uses an ink fountain to draw the pipe brick control line on the sliding layer of the top plate of the foundation, and the pipe bricks are laid first according to the control line, and then the side bricks around the pipe bricks are laid; the control method for laying the upper gas duct pipe bricks is to use a wood-made wire rod to control the wire laying according to the longitudinal center line of the coke oven. Although the traditional method can accurately position the gas duct bricks in the first layer, it is inevitable that the already laid bricks will be squeezed due to manual operation during the subsequent masonry process, which will cause the deviation of the center distance of the gas duct bricks; resulting in low accuracy of the positioning control line.

[0028] The fixing mechanism includes a limit ring 8, a limit plug plate 9, a hollow limit plug tube 10, a plurality of limit blocks 11 and an elastic column 12. The limit ring 8 is slidably installed in an installation groove 1. A through groove 1 is provided at the top of the limit ring 8, and a through hole 3 is provided at the bottom of the limit ring 8. Both the through groove 1 and the through hole 3 are connected to the through hole 1. The limit plug plate 9 is slidably installed on the through groove 1.

[0029] The hollow limit insert 10 passes through the second mounting groove, the second through hole on the caliper 6, the first through hole on the positioning rod 2, and the third through hole and the first through groove on the limit ring 8, and the hollow limit insert 10 is adapted to the second mounting groove, the second through hole, the first through hole, the third through hole and the first through groove.

[0030] A plurality of through openings are provided on the hollow limit insert 10, and a plurality of limit blocks 11 are hingedly installed on the plurality of through openings, respectively. The plurality of limit blocks 11 are respectively adapted to the plurality of through openings. An elastic column 12 is provided in the hollow limit insert 10, and the length of the elastic column 12 is equal to the length of the hollow limit insert 10 and the limit ring 8.

[0031] Limiting blocks are installed on the outer walls of both sides of the limiting plug plate 9, limiting grooves 1 are provided inside both sides of the through groove 1, and the limiting blocks are adapted to the limiting grooves 1. A through groove 2 is provided on the positioning rod 2, and the through groove 2 is communicated with the through groove 1.

[0032] According to the design dimensions of the gas pipe brick masonry drawing, calculate the size of the edge line of each pipe brick on the masonry, and then use a 10m steel ruler to pull the ruler through the stainless steel square tube laying rod composed of positioning rod 1, positioning rod 2 and positioning rod 3 4, and use a fine-refill oily marker to lay out the gas pipe brick center distance control line. The control line is marked with a marker that does not fade easily. It can be drawn in an inverted triangle marking style to facilitate positioning and verification.

[0033] After the foundation is laid, the center line of the coke oven is released and the main wall furnace head is built. After the furnace head is built, the main positioning rod composed of positioning rod 1, positioning rod 2 and positioning rod 3 4 is installed. The two calipers 6 on the main positioning rod are fixed on both sides of the furnace head, and the error between the center line of the coke oven and the center line of the main positioning rod is checked to be less than 2mm. After checking that the error is within the allowable range, the first layer of gas pipe bricks is installed. The special positioning rod has been arranged at a distance from the design size, and there is no need to use an ink line to pop out the center line of the gas pipe brick.

[0034] The positioning main rod adopts a three-section connection type, wherein a positioning rod 1, a positioning rod 2 and a positioning rod 3 4 are movably connected through a hinge 1 3 and a hinge 2 5, so that it is easy to carry and fold, providing convenience for use.

[0035] The positioning master rod is connected to the two calipers 6 by a fixing mechanism, so the caliper 6 can be separated from the positioning master rod, specifically: press the second limit stopper 13, and squeeze the spring telescopic rod 14 downward through the second limit stopper 13 to make the second limit stopper 13 lower than the bottom of the limit plug 9, then slide and pull out the limit plug 9, so that the limit plug 9 is separated from the limit ring 8, and then pull out the elastic column 12. In the absence of the elastic column 12 squeezing the first limit stopper 11, the hollow limit plug 10 can be pulled out through the limit ring 8. At this time, under the action of the second installation groove, the first limit stopper 11 can enter the hollow limit plug 10 through the through opening;

[0036] During installation, the hollow limit insert 10 is inserted into the through hole 2 on the caliper 6 through the through groove 1, through hole 3 and through hole 1 on the positioning rod 2 2 on the limit ring 8, and the bottom end of the hollow limit insert 10 is inserted into the installation groove 2, and the limit stopper 11 is also in the installation groove 2. Then, the elastic column 12 is inserted into the hollow limit insert 10, and the limit stopper 2 13 and the spring telescopic rod 14 are pressed at the same time, so that the limit plug plate 9 is inserted into the limit ring 8, and the elastic column 12 is squeezed by the limit plug plate 9, so that the elastic column 12 squeezes multiple limit stops 11, causing the limit stopper 11 to rush out of the through opening and contact the inner wall of the installation groove 2 to fix the positioning rod 2 2 and the caliper 6. At the same time, under the action of the limit stopper 2 13 and the spring telescopic rod 14, the limit plug plate 9 can be reset to limit it to prevent the limit plug plate 9 from slipping out. Similarly, the positioning rod 3 4 and the caliper 6 can be fixed.
