Technical Field

[0001] This utility model relates to the field of heating furnace technology, and in particular to a repair device for expansion joints on the top of a heating furnace. Background Technology

[0002] In industrial production, heating furnaces are indispensable key equipment in many fields such as steel smelting and ceramic firing. The expansion joint on the furnace top plays a crucial role in compensating for thermal expansion and contraction caused by temperature changes during furnace operation. When the expansion joint is damaged or the filling material fails, it needs to be repaired in a timely manner to maintain the normal operation of the heating furnace and ensure production efficiency and product quality. Traditional furnace top expansion joint repairs mostly rely on manual operation. Maintenance personnel need to carry various repair tools and materials to climb to the furnace top and manually fill the repair material, which is extremely labor-intensive and makes it difficult to guarantee the accuracy and consistency of operation, thus affecting the repair quality. To solve the above-mentioned drawbacks of manual repair, some existing furnace top expansion joint repair devices have emerged. However, current repair devices still have many technical defects. In terms of operation, many repair devices have complex structural designs and cumbersome operating procedures. Therefore, it is necessary to provide a new type of repair device for furnace top expansion joints. Utility Model Content

Detailed Implementation

[0021] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1-4 As shown, this utility model provides a repair device for expansion joints on the top of a heating furnace, including a housing 1, which is divided into upper and lower parts connected by bolts; a first handle 2, which is integrally formed with the lower half of the housing 1; a transmission mechanism installed inside the housing 1; a mounting sleeve 6 threadedly connected to one end face of the housing 1; a material tube 7, which is detachably installed on the inner wall of the mounting sleeve 6 for holding filling material; a positioning sleeve 8 threadedly connected to the end of the mounting sleeve 6 away from the housing 1, which is used to limit the position of the material tube 7; and a discharge pipe 9 detachably installed at one end of the material tube 7.

[0023] The first grip 2 has a cavity 13 inside, and a storage battery is installed inside the cavity 13. The bottom end of the first grip 2 has a charging hole 11 for charging the storage battery.

[0024] The housing 1 is equipped with a motor 14 that is electrically connected to a battery. The output end of the motor 14 is fixedly connected to a worm gear 15. The outer surface of the top end of the worm gear 15 is engaged with a worm wheel 16. The outer surfaces of both ends of the worm wheel 16 are mounted to the inner wall of the housing 1 through bearings. The outer surface of the worm wheel 16 is threadedly connected to a threaded rod 4.

[0025] A switch 12 for controlling the motor 14 is installed on the outer surface of the housing 1.

[0026] One end of the threaded rod 4 is fixedly connected to a protective plate 5, and the other end of the threaded rod 4 away from the protective plate 5 is fixedly connected to a push block 17. The push block 17 is slidably connected to the inner wall of the material tube 7. A limiting groove 19 is opened on the outer surface of the threaded rod 4, and a limiting block 3 adapted to the limiting groove 19 is fixedly connected to one end face of the housing 1.

[0027] The bottom end of the mounting sleeve 6 is fixedly connected to a second grip 10.

[0028] The housing 1 has a mounting cavity 20 for mounting the push block 17 at one end near the mounting sleeve 6.

[0029] The discharge pipe 9 is threaded to one end of the material pipe 7. The end of the discharge pipe 9 away from the material pipe 7 is beveled. A protruding plate 18 is installed on the outer surface of the discharge pipe 9.

[0030] The working principle of this device is as follows: The power source of this device is a battery installed in the cavity 13 on the first grip 2. The battery can be charged through the charging hole 11 at the bottom of the first grip 2. When the device needs to be started, the motor 14 is controlled by the switch 12 on the outer surface of the housing 1. After the motor 14 is started, the worm 15 at its output end begins to rotate. Since the worm 15 meshes with the worm wheel 16, the rotation of the worm 15 drives the worm wheel 16 to rotate on the inner wall of the housing 1 through the bearing. The outer surface of the worm wheel 16 is threaded with a threaded rod 4. When the worm wheel 16 rotates, the threaded rod 4 will move axially under the action of its thread. One end of the threaded rod 4 is connected to a protective plate 5, and the other end is connected to a push block 17. The push block 17 is inside the material tube 7. The wall slides, and at the same time, the outer surface of the threaded rod 4 has a limiting groove 19. The limiting block 3 on one end face of the housing 1 is adapted to the limiting groove 19. This can ensure that the threaded rod 4 will not rotate during the movement and can only move axially. When the threaded rod 4 moves towards the material tube 7, the push block 17 will push the filling material in the material tube 7 towards the discharge tube 9. The filling material is pushed by the push block 17 and output through the discharge tube 9. The discharge tube 9 is threaded to one end of the material tube 7, and its end away from the material tube 7 is a beveled surface. This design is conducive to the filling material being accurately filled into the expansion joint of the furnace top of the heating furnace. The protruding plate 18 on the outer surface of the discharge tube 9 is used to better control the position of the discharge tube 9 during operation and to smooth the filling material.

[0031] The housing 1 of this device is divided into upper and lower parts, which are connected by bolts to facilitate the installation and maintenance of the device. The first handle 2 is integrally formed with the lower half of the housing 1 for easy gripping by the user. The mounting sleeve 6 is threaded to one end face of the housing 1 for mounting the material tube 7. The material tube 7 is detachably mounted on the inner wall of the mounting sleeve 6. The positioning sleeve 8 is threaded to the end of the mounting sleeve 6 away from the housing 1 to limit the position of the material tube 7 and ensure the stability of the material tube 7 during operation. The bottom end of the mounting sleeve 6 is also fixed with a second handle 10 to facilitate better control of the position of the material tube 7 and the discharge tube 9 during operation.

[0032] This device has two handles, a first handle 2 and a second handle 10, which are convenient for users to hold and operate, allowing them to better control the position and direction of the device and accurately fill the expansion joint of the furnace top with filling material. The device can effectively push the filling material in the material tube 7 out through the transmission mechanism composed of motor 14, worm 15, worm wheel 16 and threaded rod 4. Compared with the manual filling method, it can provide filling power more stably and continuously, improving filling efficiency. The shell 1 is divided into upper and lower parts connected by bolts, which facilitates the maintenance and repair of internal components such as motor 14 and transmission mechanism. The detachable connection between material tube 7 and discharge tube 9, as well as the positioning sleeve 8 to limit the position of material tube 7, makes it easier to replace and clean material tube 7 and discharge tube 9 when damaged or blocked. The beveled design at the end of discharge tube 9 allows the filling material to be filled into the expansion joint more accurately, improving the quality and effect of repair. The protruding plate 18 on the outer surface of discharge tube 9 also helps to better control the discharge process and can achieve the purpose of smoothing the filling material.
