Description

Technical Field

[0001] This utility model belongs to the field of prefabricated component installation technology, specifically relating to a rapid installation and positioning structure for fire-resistant prefabricated components. Background Technology

[0002] Refractory precast components are a key part of industrial kiln linings and are widely used in high-temperature equipment such as blast furnaces, heating furnaces, and rotary kilns. Their main functions are to withstand high temperatures and resist chemical corrosion and mechanical wear.

[0003] Currently, existing refractory precast components are typically installed and fixed by directly connecting them to the steel shell with bolts. This installation method suffers from poor positioning of the precast components. Furthermore, since damaged precast components need to be replaced periodically, this connection method easily exacerbates damage to the steel shell, especially under high-temperature environments, where thermal expansion mismatch and stress concentration further increase the risk of deformation and cracking. In addition, repairs are required after precast components are damaged or detached, but the repair work is extremely cumbersome, often requiring the removal of adjacent precast components, which seriously affects production efficiency. Utility Model Content

[0004] This utility model provides a rapid installation and positioning structure for fire-resistant prefabricated components, which solves the problems mentioned in the background art, such as poor positioning effect of prefabricated components, easy damage to the steel shell, and cumbersome repair work.

[0005] The technical solution adopted in this utility model is: a rapid installation and positioning structure for fire-resistant prefabricated components, comprising:

[0006] The positioning substrate has a first mounting groove arranged in a cross pattern on its surface;

[0007] The precast component body has through mounting holes on its surface;

[0008] A metal base frame is fixedly connected to the precast component body. A second mounting groove is provided at the bottom of the metal base frame, and a sleeve that can extend into the mounting hole is installed on the metal base frame.

[0009] The connecting component is slidably connected in the first mounting slot and the second mounting slot. The connecting component has a screw hole, and a bolt can be inserted into the mounting hole of the precast body. One end of the bolt passes through the sleeve and is connected to the connecting component by means of a threaded connection.

[0010] One side of the preform body has an outwardly protruding bump, and the other side has a groove that matches the bump.

[0011] The metal base frame includes a base plate located in the middle and side plates located at both ends of the base plate and extending upwards.

[0012] The bottom of the precast component body has a through slot that matches the base plate, and the lower edges on both sides of the precast component body have inwardly recessed areas.

[0013] Anchors are provided on the surface of the base plate of the metal base frame and on the outer wall of the sleeve.

[0014] The connecting assembly includes a lower connector and an upper connector. There are two upper connectors. The upper connectors are detachably connected to the surface of the lower connectors, and the screw holes are located at the center of the lower connectors.

[0015] Both the first and second mounting slots are dovetail or T-shaped slots. The integral structure formed by the two upper connectors is installed in the second mounting slot, and the lower connector is installed in the first mounting slot.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model has a reasonable design structure. By using a positioning base plate as a foundation component to connect with the prefabricated component, damage to the steel shell is avoided. Furthermore, the prefabricated component body with a metal base frame is connected to the positioning base plate through a connecting component. Combined with the groove and protrusion structure on the side of the prefabricated component body, the accuracy of the fire-resistant prefabricated component during installation and positioning can be improved, thus enhancing the positioning effect.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] As shown in the figure, a rapid installation and positioning structure for fire-resistant prefabricated components includes:

[0031] The positioning base plate 1 has a first mounting groove 101 arranged in a cross pattern on its surface. The positioning base plate 1 can be fixed to the inner wall of the steel shell of the furnace body by bolts or welding. It can be used as a mounting base for refractory prefabricated parts, which can reduce the probability of damage to the steel shell and extend the service life of the furnace body.

[0032] The precast body 2 has through mounting holes 202 on its surface. In this example, there are two mounting holes 202, and bolts can be inserted into the mounting holes 202.

[0033] The metal base frame 3 is fixedly connected to the precast body 2. The bottom of the metal base frame 3 is provided with a second mounting groove 302, and a sleeve 304 that can extend into the mounting hole 202 is installed on the metal base frame 3. The outer wall of the sleeve 304 fits the inner diameter of the mounting hole 202, and the sleeve 304 extends to the middle position of the mounting hole 202. This can prevent the metal sleeve 304 from being heated and causing problems such as strength reduction and cracking.

[0034] The connecting component is slidably connected in the first mounting groove 101 and the second mounting groove 302. The connecting component has a screw hole 501. A bolt can be inserted into the mounting hole 202 of the precast body 2, and one end of the bolt passes through the sleeve 304 and is connected to the connecting component by a threaded connection.

[0035] One side of the preform body 2 has an outwardly protruding protrusion 201, and the other side has a groove 204 that matches the protrusion 201. In two adjacent preform bodies 2, the protrusion 201 of one preform body 2 can be placed in the groove 204 of the other preform body 2. This arrangement is mainly used to achieve precise positioning between two adjacent preform bodies 2 and improve the positioning effect.

[0036] The metal base frame 3 includes a base plate 301 located in the middle and side plates 303 located at both ends of the base plate 301 and extending upward. The bottom of the prefabricated body 2 has a through slot 205 that matches the base plate 301. The lower edges on both sides of the prefabricated body 2 have inwardly recessed areas 203. This is designed to avoid the appearance of the overall structure formed by the metal base frame 3 and the prefabricated body 2 having too many protruding structures, which would cause transportation inconvenience.

[0037] Anchors 305 are provided on the surface of the base plate 301 of the metal base frame 3 and on the outer wall of the sleeve 304. The anchors 305 are welded to the metal base frame 3 and the sleeve 304. This arrangement can improve the connection between the precast body 2 and the metal base frame 3. The anchors 305 can adopt a V-shaped or Y-shaped structure, which is not limited here.

[0038] The connecting assembly includes a lower connector 5 and an upper connector 4. There are two upper connectors 4. The upper connectors 4 are detachably connected to the surface of the lower connector 5. The screw hole 501 is opened at the center of the lower connector 5. The two upper connectors 4 are respectively connected to the lower connector 5 by screws.

[0039] Both the first mounting groove 101 and the second mounting groove 302 are dovetail grooves or T-shaped grooves. The integral structure formed by the two upper connecting parts 4 is installed in the second mounting groove 302, and the lower connecting part 5 is installed in the first mounting groove 101. This arrangement can further improve the positioning effect of the fire-resistant prefabricated parts.

[0040] When using this rapid installation and positioning structure for refractory prefabricated components, first install the positioning base plate 1 on the inner wall of the furnace steel shell, then install the integrated structure composed of the lower connector 5 and the upper connector 4 in the first mounting groove 101. After that, connect the integrated structure composed of the metal base frame 3 and the prefabricated component body 2 to the connecting assembly, and use bolts to connect the integrated structure composed of the metal base frame 3 and the prefabricated component body 2 to the connecting assembly. At this time, the bolt head is in the middle position of the mounting hole 202. In order to further avoid damage to the bolt head due to heat, the mounting hole 202 can be filled with castable or heat-insulating bar material to prevent the bolt from being heated. In this way, the installation process of the refractory prefabricated component is completed.

[0041] When refractory precast components are damaged or peel off due to long-term use, the damaged precast components can be knocked off and replaced with new refractory precast components consisting of a new precast component body 2 and a metal base frame 3. Since the upper connector 4 cannot enter the second mounting groove 302 of the metal base frame 3, the two upper connectors 4 can be disassembled, leaving only the lower connector 5 in the first mounting groove 101. This allows the bottom surface of the metal base frame 3 to contact the surface of the positioning base plate 1, and the new refractory precast component can then be installed by bolt connection, achieving a quick repair effect.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
