DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be further described below with reference to the drawings and specific embodiments. The technical solutions in the embodiments of the utility model are described clearly and completely, and the described embodiments are only part of the embodiments of the utility model, rather than all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] As Figure 1 、 2 , 3, 4, the utility model discloses a kind of adjustable height's gasification furnace masonry with arched top mould, and one embodiment of the utility model is designed, and the arched top mould in this embodiment includes hemispherical steel mold 1, and the bottom surface of steel mold 1 is evenly assembled with 5 support legs 2. Steel mold 1 is formed by the annular plate 11 of multiple coaxial settings, the diameter of each annular plate 11 is gradually decreased from bottom to top, and is assembled and fixed by connecting plate 12. The bottom surface of the lowermost annular plate 11 is evenly welded with 5 groups of plugboard 13 along the circumference, and each group of plugboard 13 includes two plate bodies, and the two plate bodies are arranged along the radial direction and side by side on the bottom surface of annular plate 11.

[0020] The support leg 2 is composed of two sections of pipe bodies in sleeve connection, which are a first pipe body 201 and a second pipe body 202. The first pipe body 201 is located at the lower side, and the second pipe body 202 is inserted into the first pipe body 201 in sleeve connection from top to bottom. Corresponding clamping grooves are punched on the two side walls of the two pipe bodies respectively, so as to facilitate positioning and auxiliary sliding of the two pipe bodies. A reinforcing sleeve is arranged on the outer side of the top end of the first pipe body 201 for reinforcing treatment. A first positioning hole is opened in the upper part of the pipe wall of the first pipe body 201, and a positioning sleeve 207 is welded on the outer side of the first positioning hole. A positioning pin 206 is slidably connected in the positioning sleeve 207, and a baffle and a pull ring 218 are welded on the outer side end of the positioning pin 206. A return tension spring 217 is sleeved between the baffle and the positioning sleeve 207, and the two ends of the return tension spring 217 are fixedly connected with the positioning sleeve 207 and the baffle respectively. A plurality of second positioning holes 213 are uniformly opened in the vertical direction on the second pipe body 202, and the hole diameter of the second positioning hole 213 is the same as that of the first positioning hole. The inner side end of the positioning pin 206 sequentially passes through the first positioning hole and the second positioning hole 213 coinciding with the first positioning hole, and the support leg 2 is positioned in height by the positioning pin 206 passing through the corresponding positioning holes of the first pipe body 201 and the second pipe body 202. A lower support plate 211 is welded on the outer periphery of the bottom end of the first pipe body 201, and a reinforcing rib plate 214 is welded between the upper side of the lower support plate 211 and the first pipe body 201. A pad 208 is assembled on the bottom surface of the lower support plate through bolts, and a spring 209 is fixed on the upper side surface of the pad 208 in the center position. The spring 209 is inserted into the first pipe body 201 upwardly, and the top part of the spring 209 is fixedly connected with the bottom end of the second pipe body 202. The spring 209 supports the second pipe body 202 and also avoids the second pipe body 202 from being pulled out of the top end of the first pipe body 201.

[0021] The top of the second pipe body 202 is provided with a socket 203, which is provided with two cavities suitable for the insertion plate 13. The second pipe body 202 is transversely provided with a notch 204 on the pipe wall at the same side of the two cavities of the socket 203. One end of the notch 204 is welded with a hinged seat, and a locking bolt 205 is rotatably connected in the hinged seat. The locking bolt 205 can be rotatably clamped in the notch 204, and the outer diameter of the locking bolt 205 is the same as the height dimension of the notch 204. The locking bolt 205 is connected with a fastening nut 215. After the locking bolt 205 is rotatably clamped in the notch 204, the fastening nut 215 is rotated to abut against the pipe wall of the second pipe body 202, so that the locking bolt 205 is positioned and cannot be rotated. The outer side of the top end of the second pipe body 202 is welded with an upper support plate 210 to increase the contact area between the top end of the support leg 2 and the steel mold 1. The bottom surface of the upper support plate 210 and the pipe wall of the second pipe body 202 are also welded with a reinforcing rib plate. In addition, a length scale line 216 is arranged on the outer side of the pipe wall of the second pipe body 202 at the side where the second positioning hole 213 is arranged. The positions of the plurality of second positioning holes 213 on the second pipe body 202 correspond to the height scale line 216. When the telescopic support leg 2 is stretched to the corresponding height, one of the second positioning holes 213 is aligned with the first positioning hole on the first pipe body 201.

[0022] The same side end surfaces of the two plate bodies of the insertion plate 13 of the steel mold 1 are provided with notches 14 with the same size as the notch 204 of the socket 203. When the insertion plate 13 is inserted into the socket 203 of the support leg 2, the notches 14 on the insertion plate 13 will coincide with the notch 204 on the side surface of the socket 203. The insertion plate 13 is locked by rotating the locking bolt 205 to be clamped in the notch 204 and the notches 14, thereby completing the assembly and fixation between the steel mold 1 and the support leg 2. In addition, in order to facilitate the quick insertion of the insertion plate 13 and the socket 203, the bottom ends of the two plate bodies of the insertion plate 13 are chamfered.

[0023] When the novel height-adjustable gasification furnace masonry arch mold is applied, the steel mold 1 is first assembled on the scaffold platform in the furnace, and then the steel mold 1 is hoisted as a whole by using a crane (or an electric hoist) through a lifting belt, so that the steel mold 1 is closely attached to the partially masonry arch bricks. Then the telescopic support leg 2 is adjusted to the desired height and is sequentially assembled and connected with the steel mold. After the support leg is installed, the crane (or the electric hoist) hook is lowered, and the lifting belt is removed. The steel mold is supported by the support leg, and then the arch bricks are masonry built by using the installed steel mold.

[0024] The above content is only the preferred embodiment of the present application, and cannot limit the implementation range of the present application. Any simple equivalent changes and modifications made according to the claims and the description of the present application still belong to the scope covered by the present application.
