Description

Technical Field

[0001] This utility model relates to the field of furnace building machine technology, specifically to a wear-resistant pneumatic hammer head structure for a furnace building machine. Background Technology

[0002] An electric frequency furnace concentrates the magnetic lines of force generated by an electric current onto the object being heated, and generates eddy currents through electromagnetic induction to heat the object. Due to various problems in the furnace construction and use process, the service life of furnace linings made of the same material varies greatly. In order to obtain a stable and long service life for the furnace lining, the furnace lining knots must be firm. To ensure that the furnace lining has sufficient firmness, a pneumatic furnace construction machine is an indispensable tool.

[0003] Currently, pneumatic furnace lining machines use pneumatic propellers to adjust the distance between the cylinder assembly and the crucible. During operation, the machine uses pneumatic hammers to strike the inner wall of the induction furnace crucible, utilizing vibration to compact and strengthen the furnace lining sand. This ensures that the sand particles of varying sizes fill the gaps, achieving a dense lining. The machine gradually pushes upwards from the bottom of the crucible, raising it 80-100 mm every 10-15 minutes, and so on.

[0004] Since pneumatic hammer cylinders are generally fixed with bolts and nuts through alignment screw holes, the lack of a preliminary limiting structure on the mounting base during screw hole alignment makes it easy for screw hole alignment to go wrong, resulting in low installation efficiency and inconvenience for personnel operation. Therefore, a wear-resistant pneumatic hammer structure for furnace building machines is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant pneumatic hammer head structure for a furnace construction machine, which solves the problem in the prior art that the screw hole alignment is prone to errors, resulting in low installation efficiency and inconvenience for personnel operation because the installation base does not have a structure to initially limit the pneumatic hammer head cylinder during the screw hole alignment process.

[0006] This utility model provides the following technical solution: a wear-resistant pneumatic hammer head structure for a furnace building machine, including a mounting base. A gas source distributor is fixedly installed on the top of the mounting base, and several sets of limiting frames are fixedly connected to the bottom of the mounting base. Each pair of limiting frames is equipped with a pneumatic hammer head assembly for contacting and impacting the crucible wall. Each set of limiting frames is equipped with a limiting component on its side for fixing the pneumatic hammer head assembly and automatically aligning the pneumatic hammer head assembly with the screw holes of the mounting base.

[0007] As a preferred embodiment of the above technical solution, the pneumatic hammer assembly includes a pneumatic hammer cylinder, the top of which is fixedly connected to a limiting plate, which is inserted between the inner sides of every two sets of limiting frames.

[0008] As a preferred embodiment of the above technical solution, each set of the limiting frame is L-shaped, and each set of the limiting frame has a slot on its side.

[0009] As a preferred embodiment of the above technical solution, the side end of the limiting plate is fixedly connected to two insert plates, each of which is inserted into each slot, and the bottom end of the insert plate is provided with an insertion hole.

[0010] As a preferred embodiment of the above technical solution, the limiting component includes a mounting box, which is fixedly connected to the side of the limiting frame. A pull plate is provided at the bottom of the outer side of the mounting box, and a connecting rod is fixedly connected to the top of the pull plate. The connecting rod is inserted into the interior of the mounting box, and a rectangular plate is fixedly connected to the top of the connecting rod. An insert rod is fixedly connected to the top of the rectangular plate, and a spring is sleeved on the outer end of the connecting rod. One end of the spring is fixedly connected to the bottom of the interior of the mounting box, and the other end of the spring is fixedly connected to the bottom of the rectangular plate.

[0011] As a preferred embodiment of the above technical solution, the mounting box is located at the bottom end of the insert plate, and the side end of the pull plate is provided with a finger groove.

[0012] As a preferred embodiment of the above technical solution, the top end of the insertion rod is sloped, and the insertion rod is adapted to the insertion hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: When the pneumatic hammer head structure of the wear-resistant furnace lining machine of this utility model is in operation, the pneumatic hammer head assembly is first placed into the two sets of limiting frames at the bottom of the mounting base. The limiting frames achieve initial limiting, and then the limiting components are activated to fix the pneumatic hammer head assembly. At the same time, the assembly is automatically and accurately aligned with the screw holes of the mounting base, eliminating the need for repeated manual adjustments. This solves the problems of easy screw hole alignment errors and low installation efficiency in traditional structures, making it convenient for personnel to operate and improving the installation speed. After the pneumatic hammer head assembly is stably installed, it can efficiently impact the crucible wall to compact the furnace lining sand, ensuring the solidity of the furnace lining.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a wear-resistant pneumatic hammer head structure for a furnace-building machine, including a mounting base 1, a gas source distributor 101 fixedly mounted on the top of the mounting base 1, and several sets of limiting frames 102 fixedly connected to the bottom of the mounting base 1. Each pair of limiting frames 102 contains a pneumatic hammer head assembly 2 for contacting and impacting the crucible wall. Each set of limiting frames 102 has a limiting component 3 on its side for fixing the pneumatic hammer head assembly 2 and automatically aligning the pneumatic hammer head assembly 2 with the screw holes of the mounting base 1. When the pneumatic hammer structure of the furnace lining machine is working, the pneumatic hammer assembly 2 is first placed into the two sets of limiting frames 102 at the bottom of the mounting base 1. The limiting frames 102 achieve initial limiting. Then, the limiting assembly 3 is activated to fix the pneumatic hammer assembly 2. At the same time, the assembly is automatically and accurately aligned with the screw holes of the mounting base 1 without the need for repeated manual adjustments. This solves the problems of easy screw hole alignment errors and low installation efficiency in traditional structures, making it convenient for personnel to operate and improving the installation speed. After the pneumatic hammer assembly 2 is stably installed, it can efficiently impact the crucible wall to compact the furnace lining sand, ensuring the solidity of the furnace lining.

[0018] As one implementation method in this embodiment, such as Figure 1 and Figure 4 As shown, the pneumatic hammer assembly 2 includes a pneumatic hammer cylinder 201. A limiting plate 202 is fixedly connected to the top of the pneumatic hammer cylinder 201. The limiting plate 202 is inserted between the inner sides of every two sets of limiting frames 102. Each set of limiting frames 102 is L-shaped. A slot 103 is provided on the side end of each set of limiting frames 102. Two insert plates 203 are fixedly connected to the side end of the limiting plate 202. Each insert plate 203 is inserted into each slot 103. Inside the 3, the bottom end of the insert plate 203 is provided with an insertion hole 204. In practice, the initial positioning is achieved by the cooperation of the limiting frame 102 and the pneumatic hammer assembly 2. The limiting plate 202 at the top of the pneumatic hammer cylinder 201 is inserted by sliding along the inner side of the two sets of L-shaped limiting frames 102. The insert plate 203 at the side end of the limiting plate 202 is simultaneously inserted into the slot 103 at the side end of the limiting frame 102 to avoid the pneumatic hammer cylinder 201 from shifting during installation and to prepare for the alignment of the screw holes.

[0019] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, the limiting component 3 includes a mounting box 301, which is fixedly connected to the side of the limiting frame 102. A pull plate 302 is provided at the bottom outer end of the mounting box 301. A connecting rod 304 is fixedly connected to the top of the pull plate 302. The connecting rod 304 is inserted into the interior of the mounting box 301. A rectangular plate 305 is fixedly connected to the top of the connecting rod 304. An insertion rod 306 is fixedly connected to the top of the rectangular plate 305. A spring 307 is sleeved on the outer end of the connecting rod 304. One end of the spring 307 is fixedly connected to the bottom inner end of the mounting box 301, and the other end is fixedly connected to the bottom end of the rectangular plate 305. The mounting box 301 is located at the bottom of the insertion plate 203. A finger groove 303 is provided on the side of the pull plate 302. The top of the insertion rod 306 is sloped and matches the insertion hole 204. During implementation, during insertion, the bottom end of the insertion plate 203... The insertion rod 306, which is sloped in the limiting component 3, contacts the top of the insertion plate 203. The sloped design reduces the pressure resistance of the insertion plate 203, causing the insertion plate 203 to push the insertion rod 306 downward. The insertion rod 306 drives the rectangular plate 305 to compress the spring 307 in the mounting box 301 through the connecting rod 304. The spring 307 contracts and stores elastic potential energy. When the insertion plate 203 continues to move until the insertion hole 204 at the bottom is aligned with the insertion rod 306, the spring 307 releases its potential energy to push the rectangular plate 305 upward, causing the insertion rod 306 to be accurately inserted into the insertion hole 204, thus completing the limiting and fixing of the pneumatic hammer assembly 2. Subsequently, by removing the fastener 205 and pulling down the pull plate 302 (with the groove 303 for easy pulling by personnel), the insertion rod 306 is disengaged from the insertion hole 204, and the limiting plate 202 can be removed from between the limiting frames 102, completing the disassembly of the pneumatic hammer assembly 2, which is convenient and quick.

[0020] Working principle: When installing the pneumatic hammer head structure of this wear-resistant furnace building machine, the initial positioning is achieved by the cooperation of the limiting frame 102 and the pneumatic hammer head assembly 2. The limiting plate 202 at the top of the pneumatic hammer head cylinder 201 is inserted into the inner side of the two sets of L-shaped limiting frames 102. The insert plate 203 at the side end of the limiting plate 202 is inserted into the slot 103 at the side end of the limiting frame 102 at the same time to avoid the pneumatic hammer head cylinder 201 from shifting during installation and to prepare for the alignment of the screw holes.

[0021] During insertion, the bottom end of the insert plate 203 contacts the top end of the inclined insert rod 306 in the limiting component 3. The inclined design reduces the pressure resistance of the insert plate 203, causing the insert plate 203 to push the insert rod 306 downward. The insert rod 306 drives the rectangular plate 305 to compress the spring 307 in the mounting box 301 through the connecting rod 304. The spring 307 contracts and stores elastic potential energy. When the insert plate 203 continues to move until the insertion hole 204 at the bottom end is aligned with the position of the insert rod 306, the spring 307 releases its potential energy to push the rectangular plate 305 upward, causing the insert rod 306 to be accurately inserted into the insertion hole 204, thus completing the limiting and fixing of the pneumatic hammer assembly 2. At this point, the pre-set screw holes of the limit frame 102, the limit plate 202, and the mounting base 1 are automatically and accurately aligned, eliminating the need for repeated manual adjustments. This solves the problem of incorrect screw hole alignment and low installation efficiency caused by the lack of initial positioning in traditional structures. Subsequently, the bolts and nuts 205 can be used to fasten the screw holes, making the operation convenient and significantly improving installation efficiency. At the same time, after the pneumatic hammer cylinder 201 is stably installed, it can vibrate the furnace lining sand by impacting the crucible wall, ensuring the firmness of the furnace lining, extending the service life of the furnace lining, and meeting the wear-resistant and high-efficiency operation requirements of the furnace building machine.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
