Description

Technical Field

[0001] The utility model relates to the technical field of furnace wall vibration balancers.

[0002] Specifically, it relates to a pneumatic shock absorbing balancer. Background Art

[0003] Existing furnace-building machines require a balancer to adjust and correct deviation during the furnace-building process, and the balancer is also equipped with a shock-absorbing device. In the prior art, the shock absorption of the balancer is achieved by installing a spring on the connecting rod mechanism. For example, our company developed a first-generation vibration balancer with the Chinese utility model patent application number CN202121243506.7. However, with actual use, new problems have emerged: during the vibration of the furnace, all forces act on the spring, making it prone to breakage. Moreover, the vibration during the furnace-building process is very large, often compressing the spring to its limit. This can cause collisions between parts, damage parts in the connecting rod mechanism, and shorten the service life of the balancer. Utility Model Content

[0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned traditional technology and to provide a pneumatic shock absorbing balancer in view of the deficiencies of the existing technology.

[0005] The purpose of the utility model is achieved through the following technical measures: a pneumatic shock-absorbing balancer, comprising a main disk, a distributor is provided at the center of the main disk, a balancing turntable is mounted on the outer side of the distributor, a plurality of air hammers are provided circumferentially of the main disk, and a probe is connected to the air hammer. The utility model is characterized in that a shock absorber and a connecting rod are provided between the probe and the balancing turntable, a shift fork is provided at one end of the connecting rod close to the shock absorber, a gas cavity is provided in the shock absorber, the shift fork is connected to the shock absorber and can slide along the shock absorber to compress the gas in the gas cavity.

[0006] As an improvement of the above technical solution: the shock absorber includes a shell, a gas cavity is provided in the shell, a piston push rod is installed in the gas cavity, the piston push rod can slide along the gas cavity, and the piston push rod is fixedly connected to the shift fork.

[0007] As an improvement of the above technical solution: the piston push rod divides the gas cavity into a first gas cavity and a second gas cavity at both ends, and the piston push rod is located between the first gas cavity and the second gas cavity, separating the first gas cavity and the second gas cavity, so that the first gas cavity and the second gas cavity are independent of each other.

[0008] As an improvement to the above technical solution: the gas in the first gas cavity and the second gas cavity can only enter but not exit, the first gas cavity is connected to a first inflation tube for replenishing gas, and the second gas cavity is connected to a second inflation tube for replenishing gas.

[0009] As an improvement to the above technical solution: a first return spring is installed in the first gas cavity, and a second return spring is installed in the second gas cavity.

[0010] As an improvement to the above technical solution: a sliding groove is provided on the housing along the movement direction of the piston push rod, and the sliding groove is a through groove, which connects the interior of the housing with the outside.

[0011] As an improvement to the above technical solution: the piston push rod is connected to the shift fork through a flat pin, and a flat pin sleeve is fixedly sleeved on the piston push rod. One end of the flat pin is fixedly connected to the shift fork, and the other end passes through a slide groove and is fixedly connected to the flat pin sleeve.

[0012] As an improvement to the above technical solution: the connecting rod and the balance turntable are hinged via a first rotating head, and the shock absorber and the probe are hinged via a second rotating head.

Even if compressed, the piston push rod will not collide with the end of the shock absorber during movement. Compared with the spring shock absorption in the existing technology, there will be no collision between parts. The compression force acts on the gas, and there is no situation like the spring being compressed to the bottom. The parts will not be damaged by collision, which can effectively improve the buffering effect, thereby effectively protecting the shock absorber and extending its service life.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example: As shown in the attached Figure 1-3 As shown, a pneumatic shock-absorbing balancer comprises a main plate 1 with a distributor 2 disposed at its center. A balancing disc 3 is mounted on the outer side of the distributor 2. Multiple air hammers 4 are arranged around the main plate 1, each connected to a probe 5. In this embodiment, a shock absorber 6 and a connecting rod 7 are disposed between the probe 5 and the balancing disc 3. A shift fork 8 is disposed at one end of the connecting rod 7 near the shock absorber 6. A gas cavity is defined within the shock absorber 6. The shift fork 8 is connected to the shock absorber 6 and can slide along the shock absorber 6 to compress the gas within the gas cavity.

[0020] like Figure 1-3 As shown, in this embodiment, the shock absorber 6 includes a housing 9, which has a gas cavity disposed therein. A piston push rod 10 is mounted within the gas cavity. The piston push rod 10 can slide along the gas cavity and divide the gas cavity into a first gas cavity 11 and a second gas cavity 12 at either end. The piston push rod 10 is located between the first gas cavity 11 and the second gas cavity 12, separating the first gas cavity 11 and the second gas cavity 12 so that the first gas cavity 11 and the second gas cavity 12 are independent of each other. The gas in the first gas cavity 11 and the second gas cavity 12 can only enter but not exit. The first gas cavity 11 is connected to a first inflation pipe 13 for replenishing gas into the first gas cavity 11, and the second gas cavity 12 is connected to a second inflation pipe 14 for replenishing gas into the second gas cavity 12, ensuring that the air pressure in the first gas cavity 11 and the second gas cavity 12 is always maintained at a set state and does not decrease.

[0021] In this embodiment, the end away from the connecting rod 7 is defined as the first gas cavity 11 , and the end close to the connecting rod 7 is defined as the second gas cavity 12 , and vice versa.

[0022] The shift fork 8 is fixedly connected to the piston push rod 10. During movement, the probe 5 drives the shock absorber 6 to move, and the piston push rod 10 moves toward the first gas cavity 11 or the second gas cavity 12 under the action of the shift fork 8, compressing the gas in the first gas cavity 11 or the second gas cavity 12, thereby achieving buffering and shock absorption. The first gas cavity 11 and the second gas cavity 12 are filled with gas, and buffering and shock absorption are achieved by compressing the gas during movement. The gas in the first gas cavity 11 and the second gas cavity 12 only enters but does not exit, and there is always gas. Even if compressed, the piston push rod 10 will not collide with the end of the shock absorber 6 during movement. Compared with the spring shock absorption in the prior art, there will be no collision between parts. The compression force acts on the gas, and there is no situation like the spring being compressed to the bottom. The parts will not be damaged by collision, which can effectively improve the buffering effect, thereby effectively protecting the shock absorber 6 and extending its service life.

[0023] like Figure 2-3 As shown, a first return spring 15 is installed in the first gas cavity 11, and a second return spring 16 is installed in the second gas cavity 12. After the piston push rod 10 moves toward the first gas cavity 11 and compresses the air inside to provide overall cushioning and shock absorption, the first return spring 15 pushes the piston push rod 10 back to its original position. After the piston push rod 10 moves toward the second gas cavity 12 and compresses the air inside to provide overall cushioning and shock absorption, the second return spring 16 pushes the piston push rod 10 back to its original position.

[0024] like Figure 2 As shown, a chute 17 is provided on the housing 9 along the direction of movement of the piston push rod 10. This chute 17 is a through slot that connects the interior of the housing 9 with the outside world. The piston push rod 10 is connected to the shift fork 8 via a flat pin 21. A flat pin sleeve 22 is fixedly mounted on the piston push rod 10. One end of the flat pin 21 is fixedly connected to the shift fork 8, and the other end passes through the chute 17 and is fixedly connected to the flat pin sleeve 22.

[0025] The shift fork 8 and the connecting rod 7 are integrally provided, or they can be separately provided. If they are separately provided, the two can be fixedly connected.

[0026] like Figure 1-3 As shown, the connecting rod 7 is connected to the balancing turntable 3 via a first turret 18, and the shock absorber 6 is connected to the probe 5 via a second turret 19. Both the first turret 18 and the second turret 19 are U-shaped hinged joints. One end of the first turret 18 is fixed to the connecting rod 7, and the other end is connected to the balancing turntable 3 via a hinge shaft. The probe 5 includes a ruler body arranged along the direction of movement of the air hammer 4 and a ruler seat 20 fixedly connected to the air hammer 4. One end of the second turret 19 is fixed to the housing 9 of the shock absorber 6. The ruler seat 20 extends along the surface of the main plate 1 and is hinged to the other end of the second turret 19 via a hinge shaft.

[0027] In this embodiment, three air hammers 4 are arranged along the circumference of the main disk 1. The number of air hammers 4 can be set according to actual conditions and is not specifically limited. The probe 5 corresponds to the air hammer 4 one by one. A balancing turntable 3 is also provided, which is circular. The balancing turntable 3 is concentrically arranged with the distributor 2 and is connected by a bearing so that the balancing turntable 3 can rotate freely along the distributor 2. The connection points between the shock absorber 6 and the balancing turntable 3 are evenly distributed along the circumference of the balancing turntable 3. Multiple connection points can be set along the circumference of the balancing turntable 3. However, in this embodiment, there are three groups of shock absorbers 6, and there are three connection points with the balancing turntable 3.

[0028] During use, the gas source passes the gas into the air hammer 4 through the distributor 2 and pushes the air hammer 4 to move forward. The three air hammers 4 move forward and at the same time drive their corresponding probes 5 to move forward. The probes 5 drive the corresponding shock absorbers to pull the balance turntable 3 to rotate. If the distance that one or two air hammers 4 move forward is different from the others due to unstable shaking of the machine, the corresponding shock absorber will exert a greater pulling force on the balance turntable 3, thereby increasing the rotation angle of the balance turntable 3. Since the three shock absorbers are centrally symmetrical along the balance turntable 3, the balance turntable 3 will drive the shock absorbers corresponding to the other air hammers 4 to increase the movement amplitude, and the shock absorber will react on the corresponding air hammer 4, so that the three shock absorbers always move at the same time under the drive of the balance turntable 3, and the movement amplitude is always equal, thereby achieving the purpose of synchronous adjustment of the air hammers 4 when the furnace is struck.
