Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a wear-resistant liner cutting device for environmentally friendly boilers. Background Technology

[0002] Boiler wear-resistant liners are structural components used to protect the interior of boilers. They are typically made of alumina as the main raw material, a special corundum ceramic that is fired at high temperatures, and then combined with rubber or high-strength adhesives. They are key components for reducing wear and extending the service life of equipment.

[0003] When installing the wear-resistant liner of the boiler, it is necessary to cut the wear-resistant liner according to the actual assembly requirements. Due to the limited operating space, it is difficult to cut it with large machines. At present, during the cutting process of the wear-resistant liner, one person needs to hold the cutting device to cut the liner, and another person needs to spray water to cool the cutting position to prevent damage to the cutting device and the wear-resistant liner.

[0004] However, working together in a limited space is cramped and can easily lead to danger during the cutting process, and it also wastes manpower. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant liner cutting device for environmentally friendly boilers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wear-resistant liner cutting device for environmentally friendly boilers, comprising:

[0008] The main body of the cutting device has a cutting blade installed at its output end. A mounting base is fixedly installed on the surface of the main body of the cutting device. A water outlet pipe is connected to one side of the mounting base, and a water inlet pipe is connected to the other side of the mounting base.

[0009] A rotating mandrel is rotatably mounted inside the mounting base. A water passage hole is opened on the surface of the rotating mandrel, and a second mounting shaft is provided at one end of the rotating mandrel.

[0010] A connecting rod is sleeved on the surface of the second mounting shaft, and a trigger rod is connected to one end of the connecting rod.

[0011] Preferably, the mounting base has a torsion spring groove inside, and a stop block is fixedly installed on the surface of the mounting base.

[0012] Preferably, the inlet pipe and the outlet pipe are connected internally through the mounting base, and a spray cap is installed at the end of the outlet pipe, with the spray cap corresponding to the cutting blade.

[0013] Preferably, one end of the rotating spindle is fixedly connected to a first mounting shaft, the first mounting shaft is inserted into the inside of the torsion spring groove, and a torsion spring is connected between the first mounting shaft and the inner wall of the torsion spring groove.

[0014] Preferably, the water passage hole passes through the rotating mandrel, and the two ends of the water passage hole are respectively provided with the water outlet pipe and the water inlet pipe, and the two ends of the water passage hole have a fan-shaped opening.

[0015] Preferably, the second mounting shaft is located at the end of the rotating spindle away from the first mounting shaft, and the second mounting shaft passes through the mounting base.

[0016] Preferably, the connecting rod is located at the end of the mounting base away from the main body of the cutting device, the connecting rod is fixedly connected to the second mounting shaft, and the bottom surface of the connecting rod is in contact with the stop block.

[0017] Preferably, the trigger rod and the connecting rod are an integral structure, and the trigger rod is an arc-shaped plate structure coaxial with the main body of the cutting device.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting up a spray cap and a trigger rod, during the cutting process, the trigger rod is squeezed and drives the rotating spindle to rotate, so that the two ends of the water passage hole are connected to the water outlet pipe and the water inlet pipe respectively. This allows the cooling water to pass through the water passage hole and be sprayed onto the cutting disc through the spray cap. This enables a single person to operate and cool the cutting disc during the grinding process, avoiding the need for two or more people to be in a confined space at the same time, reducing the probability of danger, and saving manpower.

[0020] 2. By setting a torsion spring, when the cutting disc is moved away from the wear-resistant liner, the trigger rod returns to its initial position under the rebound force of the torsion spring, driving the rotating spindle to rotate. This disconnects the two ends of the water passage from the water outlet and water inlet pipes, preventing the cooling water from continuing to spray. This stops the spraying of cooling water at the same time as stopping the cutting, saving cooling water and avoiding excess cooling water from polluting the work site, thus improving environmental protection.

[0031] Please see the appendix Figure 1 To be continued Figure 4 As shown, this utility model provides a wear-resistant liner cutting device for environmentally friendly boilers, comprising:

[0032] The cutting device body 1 has a cutting blade 11 installed at its output end. A mounting base 2 is fixedly installed on the surface of the cutting device body 1. A torsion spring groove 25 is opened inside the mounting base 2. A stop block 24 is fixedly installed on the surface of the mounting base 2. A water outlet pipe 21 is connected to one side of the mounting base 2, and a water inlet pipe 23 is connected to the other side of the mounting base 2. The water inlet pipe 23 and the water outlet pipe 21 are connected through the interior of the mounting base 2. A spray cap 22 is installed at the end of the water outlet pipe 21, and the spray cap 22 is correspondingly arranged with the cutting blade 11.

[0033] A rotating spindle 4 is rotatably disposed inside the mounting base 2. One end of the rotating spindle 4 is fixedly connected to a first mounting shaft 42, which is inserted into the inside of a torsion spring groove 25. A torsion spring 3 is connected between the first mounting shaft 42 and the inner wall of the torsion spring groove 25. A water passage hole 41 is formed on the surface of the rotating spindle 4, which penetrates the rotating spindle 4. The two ends of the water passage hole 41 are respectively corresponding to the water outlet pipe 21 and the water inlet pipe 23. The two ends of the water passage hole 41 are fan-shaped openings. A second mounting shaft 43 is provided at one end of the rotating spindle 4, which is located at the end of the rotating spindle 4 away from the first mounting shaft 42. The second mounting shaft 43 penetrates the mounting base 2.

[0034] A connecting rod 5 is sleeved on the surface of the second mounting shaft 43. The connecting rod 5 is located at the end of the mounting base 2 away from the main body 1 of the cutting device. The connecting rod 5 is fixedly connected to the second mounting shaft 43. The bottom surface of the connecting rod 5 is in contact with the stop block 24. One end of the connecting rod 5 is connected to a trigger rod 51. The trigger rod 51 and the connecting rod 5 are an integral structure. The trigger rod 51 is an arc-shaped plate structure coaxial with the main body 1 of the cutting device.

[0035] This utility model proposes a wear-resistant liner cutting device for environmentally friendly boilers. In use, the main body 1 of the cutting device is connected to a power source, and the inlet pipe 23 is connected to a water pump. During the cutting process, the switch of the main body 1 is turned on, and the cutting blade 11 rotates to cut. The trigger rod 51 contacts the wear-resistant liner before the cutting blade 11 contacts it. During the pushing of the cutting blade 11 towards the wear-resistant liner, the trigger rod 51 is compressed, causing the connecting rod 5 to swing. The connecting rod 5 drives the rotating spindle 4 to rotate via the second mounting shaft 43, connecting the two ends of the water passage hole 41 to the outlet pipe 21 and the inlet pipe 23 respectively. This allows cooling water to pass through the water passage hole 41 and be sprayed onto the cutting blade 11 via the spray cap 22. This allows for single-person operation to cool the cutting blade 11 during the grinding process, avoiding the need for two or more people to be in a confined space simultaneously, reducing the probability of danger, and saving manpower.

[0036] As a further improvement of this utility model, by setting a torsion spring 3, when the cutting blade 11 is moved away from the wear-resistant liner, the trigger rod 51 returns to the initial position under the rebound force of the torsion spring 3, driving the rotating spindle 4 to rotate, so that the two ends of the water passage 41 are disconnected from the water outlet pipe 21 and the water inlet pipe 23, preventing the cooling water from continuing to spray, thus stopping the spraying of cooling water at the same time as stopping the cutting, saving cooling water and avoiding the pollution of the work site by excess cooling water, thereby improving environmental protection.

[0037] Working Principle: The wear-resistant liner plate is used to protect the internal structure of the boiler. This utility model proposes a wear-resistant liner plate cutting device for environmentally friendly boilers. In use, the main body 1 of the cutting device is connected to a power source, and the water inlet pipe 23 is connected to a water pump. During the cutting process, the switch of the main body 1 of the cutting device is turned on, and the cutting blade 11 rotates to cut. The trigger rod 51 contacts the wear-resistant liner plate before the cutting blade 11 contacts it. During the process of pushing the cutting blade 11 towards the wear-resistant liner plate, the trigger rod 51 is compressed, causing the connecting rod 5 to swing. The connecting rod 5 drives the rotating spindle 4 to rotate via the second mounting shaft 43, causing the two ends of the water passage hole 41 to... The water outlet pipe 21 and the water inlet pipe 23 are connected, so that the cooling water passes through the water passage hole 41 and is sprayed onto the cutting blade 11 through the spray cap 22. This allows for single-person operation to cool the cutting blade 11 during the grinding process. When the cutting blade 11 is moved away from the wear-resistant liner, the trigger rod 51 returns to its initial position under the rebound force of the torsion spring 3, which drives the rotating spindle 4 to rotate. This disconnects the two ends of the water passage hole 41 from the water outlet pipe 21 and the water inlet pipe 23, preventing the cooling water from continuing to spray. This stops the spraying of cooling water at the same time as stopping the cutting, saving cooling water and avoiding pollution of the work site by excess cooling water, thus improving environmental protection.
