Description

Technical Field

[0001] The utility model relates to the technical field of furnace building machines.

[0002] Specifically, the invention relates to a multi-layer furnace building machine. Background Art

[0003] Various problems arise during the construction and operation of electric frequency furnaces, and the service life of linings made of the same material varies significantly. To ensure a stable and long service life, the lining must be firmly knotted. To ensure this sufficient lining strength, a furnace builder is an essential tool. Currently, furnace builder machines use a single-layer pneumatic hammer to create knots. However, even with sufficient air pressure at the furnace site, a single-layer hammer is slow and inefficient. Since only one furnace builder can be installed in a single furnace, a furnace builder with high efficiency, even with sufficient air pressure, is urgently needed to address these issues. 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 multi-layer furnace building machine in view of the deficiencies of the existing technology.

[0005] The purpose of the present utility model is achieved through the following technical measures: a multi-layer furnace building machine, characterized in that: it includes a main disk, the main disk is provided with multiple layers, the multiple main disks are parallel to each other and concentrically arranged, each layer of the main disk is provided with multiple air hammers along the circumference, the multiple air hammers are evenly distributed along the circumference of their respective corresponding main disks, the air hammers are connected to feelers, and the air hammers and feelers are arranged in a one-to-one correspondence.

[0006] As an improvement to the above technical solution: a distributor is installed at the center of the uppermost main disk, and the air source passes the gas into the air hammer through the distributor and pushes the air hammer to move forward.

[0007] As an improvement to the above technical solution: the air pressure from the distributor to the main disk increases gradually from top to bottom.

[0008] As an improvement to the above technical solution: a pressure regulating valve is provided between the distributor and the air hammer on the upper main disk, and a pressure gauge is installed on one side of the pressure regulating valve.

[0009] As an improvement of the above technical solution: a balancing turntable is mounted on the outside of the distributor, the balancing turntable is concentrically arranged with the distributor and connected through a bearing, and a balancer is arranged between the probe corresponding to the air hammer on the top main disk and the balancing turntable.

[0010] As an improvement of the above technical solution: the balancer includes a shock absorber and a connecting rod, 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] Due to the adoption of the above technical scheme, the advantages of the present invention compared with the existing technology are: by setting up multiple layers of main disks, each layer of main disk is equipped with its own corresponding air hammer, and the multiple layers of air hammers operate simultaneously, the knotting area is expanded, which can effectively improve the furnace building efficiency. After field practice, compared with the single-layer furnace building machine in the existing technology, the double-layer main disk furnace building can save one-third of the furnace building time; the air pressure supplied to the upper air hammer is controlled by the pressure regulating valve, so that the air pressure of each layer of air hammer is gradually increased from top to bottom. Since knots are tied from bottom to top when building the furnace, the air pressure of the upper air hammer is small, and the knotting force is also small. The furnace lining is first pre-vibrated by an air hammer with smaller force, and then actually vibrated by an air hammer with larger force. Compared with directly using large impact force for knotting, the solidity of the furnace wall can be improved, and the knotting quality can be effectively improved.

[0020] 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.

[0021] Example: As shown in the attached Figure 1-3 As shown, a multi-layer furnace building machine includes a main disk 1, and a plurality of air hammers 4 are arranged circumferentially on the main disk 1, and the plurality of air hammers 4 are evenly distributed along the circumference of the main disk 1. A probe 5 is connected to the air hammer 4, and the air hammer 4 and the probe 5 are arranged in a one-to-one correspondence. The main disk 1 is provided with multiple layers, and the multiple layers of main disks 1 are arranged parallel to each other and concentrically. In this embodiment, there are two layers of main disks 1, and three air hammers 4 are installed on each layer of main disk 1. When beating the furnace, the six air hammers 4 work together to gradually knot the furnace lining from bottom to top. The multi-layer air hammers 4 expand the knotting area, which can effectively improve the efficiency of furnace building. According to field practice, compared with the single-layer furnace building machine in the prior art, the double-layer main disk 1 can save one-third of the furnace building time when building the furnace. It can also be set to three layers, four layers, etc. according to actual conditions, as long as the on-site air pressure is sufficient.

[0022] like Figure 1-2 As shown, a distributor 2 is mounted in the center of the topmost main disk 1. During operation, the air source passes gas through the distributor 2 into the air hammers 4, propelling them forward. A balancing turntable 3 is mounted on the outside of the distributor 2. Balancers 23 are positioned between the sounding rods 5 corresponding to the air hammers 4 on the topmost main disk 1 and the balancing turntable 3. Balancers 23 are positioned one-to-one with the sounding rods 5, with multiple balancers 23 arranged in a circular array around the center of the balancing turntable 3. In this embodiment, three sets of air hammers 4, three corresponding sounding rods 5, and three corresponding balancers are positioned on the topmost main disk 1.

[0023] 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 balancer 23 and the balancing turntable 3 are evenly distributed along the circumference of the balancing turntable 3. The balancing turntable 3 can be provided with multiple connection points along the circumference. However, in this embodiment, there are three groups of balancers, and there are also three connection points with the balancing turntable 3.

[0024] The air pressure from the distributor 2 to the main disk 1 gradually increases from top to bottom. A pressure regulating valve 24 is provided between the distributor 2 and the air hammer 4 on the upper main disk 1. A pressure gauge 25 is installed on one side of the pressure regulating valve 24 to display the gas pressure to the air hammer 4 in real time. The air pressure supplied to the upper air hammer 4 is controlled by the pressure regulating valve 24, so that the air pressure of each layer of air hammer 4 gradually increases from top to bottom. Since knots are tied from bottom to top when building a furnace, the air pressure of the upper air hammer 4 is small, and the knotting force is also small. The furnace lining is first pre-vibrated by the air hammer 4 with smaller force, and then actually vibrated by the air hammer 4 with larger force. Compared with knotting directly using large impact force, the firmness of the furnace wall can be improved, and the knotting quality can be effectively improved. Since it is necessary to control the air pressure of the air hammer 4 from top to bottom to gradually increase, there is no need to install a pressure regulating valve 24 between the bottom air hammer 4 and the distributor 2, and the bottom air hammer 4 can be directly supplied with air.

[0025] like Figure 2-3 As shown, in this embodiment, the balancer includes a shock absorber 6 and a connecting rod 7. A shift fork 8 is provided at one end of the connecting rod 7 near the shock absorber 6. A gas cavity is provided in the shock absorber 6. The shift fork 8 is connected to the shock absorber 6 and can slide along the shock absorber to compress the gas in the gas cavity.

[0026] like Figure 2-3 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.
