Whether it is a "tower" type furnace or a "Π" type furnace, its interior is composed of many heating surfaces, and it needs to be equipped with water-cooled wall tube rows to achieve cooling of the heating surfaces. In view of the large size of the water-cooled wall tube row and the large number of installations required, the existing lifting equipment has fixed lifting points during the lifting process, and the lifting point position cannot be adjusted according to the specific size of the water-cooled wall tube row. This makes it difficult to ensure stability during the lifting process, and the tube row is unevenly stressed, which is easy to cause damage. To this end, we proposed a water-cooled wall tube row lifting tool. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The utility model provides a technical solution: a water-cooled wall tube row hoisting tool, which is mainly used for the hoisting of water-cooled wall tube rows, economizers, reheaters, and superheater tube rows, including a fixing frame 1, a connecting frame 2 is welded and fixed on the top of the fixing frame 1, and the number of the connecting frames 2 is at least four. By setting the end of the rope in the connecting frame 2, the fixing frame 1 is connected to a lifting device such as a crane by setting the connecting frame 2. The setting of four connecting frames 2 can increase the overall stability of the fixing frame 1 during the hoisting process. The bottom of the fixing frame 1 is provided with an assembly groove 3, and the number of the assembly groove 3 is at least four groups. Each group of the assembly grooves 3 is respectively equipped with an assembly frame 4, and the two assembly grooves 3 of each group are symmetrically opened on the fixing frame 1 in the front and rear. The bottom of the assembly frame 4 is detachably fixedly connected to the assembly groove 3 through a connecting component 5. By setting the connecting component 5, the assembly frame 4 can be adjusted to a short-distance fixed position in the assembly groove 3, so that in the process of hoisting the water-cooled wall tube row, it is convenient to adjust the position of the hanging point according to the specific size of the tube row, so that the utility model can hoist water-cooled wall tube rows of different sizes more stably. The bottom of the assembly frame 4 is symmetrically fixedly equipped with a fixing mechanism 6 in the front and rear. The fixing mechanism 6 is used to be fixedly connected to one end of the rope, and the other end of the rope is sleeved on the hoisting point of the water-cooled wall tube row.

[0021] like Figure 2As shown in the figure, the connecting component 5 includes a connecting block 51, which is integrally formed at the top of the assembly frame 4. There are two connecting blocks 51, and the two connecting blocks 51 are symmetrically distributed in the front and rear and are respectively inserted into the assembly slot 3. The side walls of the connecting blocks 51 are provided with connecting holes 52 symmetrically distributed in the left and right directions. The connecting holes 52 penetrate the connecting blocks 51, and the side walls of the fixing frame 1 are evenly provided with positioning holes 53 penetrating into the assembly slot 3. The side walls of the fixing frame 1 are screwed with positioning bolts 54 penetrating the positioning holes 53 and the connecting holes 52. By screwing the positioning bolts 54 into the connecting holes 52, the connection and fixation of the assembly frame 4 and the assembly slot 3 are achieved. The connection and fixation of the connecting blocks 51 and the assembly slot 3 from the front and rear directions can enhance the stability of the fixation between the assembly frame 4 and the fixing frame 1.

[0022] like Figure 3 , Figure 4 and Figure 5 As shown in the figure, the fixing mechanism 6 includes a first fixing plate 61 and a second fixing plate 62, and the first fixing plate 61 and the second fixing plate 62 are welded and fixed to the bottom of the assembly frame 4, and the side wall of the first fixing plate 61 is inserted with a fixing bolt 63 that is screwed to the second fixing plate 62, and the side wall of the fixing bolt 63 is provided with an annular groove 631 for rope sleeve. The rope is sleeved in the annular groove 631, so that the rope can be located between the first fixing plate 61 and the second fixing plate 62, and the rope is limited by the first fixing plate 61 and the second fixing plate 62 to prevent the rope from falling off from between the first fixing plate 61 and the second fixing plate 62 during the lifting process.

[0023] A clamping assembly 7 is installed between the side wall of the first fixing plate 61 and the fixing bolt 63. After the fixing bolt 63 is screwed to the installation position by the provided clamping assembly 7, the position of the fixing bolt 63 is clamped and fixed to avoid the fixing bolt 63 being driven by the rope to rotate in the first fixing plate 61 and the second fixing plate 62 during the process of using the rope to hoist the water-cooled wall tube row. The connection between the fixing bolt 63 and the first fixing plate 61 and the second fixing plate 62 is unstable, making the rope connected with the fixing bolt 63 easy to fall off, thereby causing a safety accident during the hoisting process.

[0024] like Figure 3 and Figure 4As shown in the figure, the clamping assembly 7 includes a mounting frame 71, which is welded and fixed to the side wall of the first fixing plate 61, and a mounting block 72 is slidably assembled in the mounting frame 71. A clamping pin 73 that penetrates the mounting frame 71 and is symmetrically distributed on the left and right is welded and fixed on the top of the mounting block 72. A clamping groove 74 corresponding to the clamping pin 73 is opened on the side wall of the fixing bolt 63. The clamping pin 73 is clamped into the clamping groove 74 to limit and fix the connection position of the fixing bolt 63 and the first fixing plate 61 and the second fixing plate 62, thereby increasing the fixing To ensure the stability of the bolt 63, the bottom of the mounting block 72 is fixedly connected to a handle frame 75 that passes through the mounting frame 71, and a spring 76 is fixedly assembled between the bottom of the mounting block 72 and the mounting frame 71. The elastic force generated by the spring 76 on the mounting block 72 keeps the connection position of the pin 73 with the slot 74 stable. After the mounting block 72 is driven downward by the handle frame 75 and the pin 73 is moved out of the slot 74, the fixing bolt 63 can be disassembled, which facilitates the maintenance and replacement of the rope assembled on the outer wall of the fixing bolt 63.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown in the figure, the side wall of the fixing bolt 63 is provided with marking grooves 8 which are symmetrically distributed on the left and right, and the side wall of the first fixing plate 61 is welded and fixed with marking blocks 9 which are symmetrically distributed on the left and right. In the process of assembling and fixing the fixing bolt 63 with the first fixing plate 61 and the second fixing plate 62, the marking grooves 8 and the marking blocks 9 are used to facilitate the judgment of the position of the card slot 74, and to facilitate the docking of the position between the card slot 74 and the card pin 73.

[0026] Working principle: Figure 6 As shown in , during the use of the utility model, first, the rope passing through the connecting frame 2 is connected to a lifting device such as a crane, and a lifting point is set according to the size of the water-cooled wall tube row to be lifted. The relative position between the assembly frame 4 and the assembly groove 3 is adjusted according to the lifting point. The adjustment process is simple and convenient. Then, one end of the rope is connected to the fixing mechanism 6, and the other end of the rope is sleeved on the lifting point of the water-cooled wall tube row. The lifting operation of the water-cooled wall tube row can be completed. When the rope is worn and needs maintenance and replacement, the handle frame 75 is pulled downward, and then the fixing bolt 63 and the first fixing plate 61 and the second fixing plate 62 are disassembled, and the rope can be maintained and replaced later.
