Description

Technical Field

[0001] This invention relates to the field of hoisting technology, and in particular to a hoisting device for the top of a lifting furnace made of silicon carbide composite ceramic material. Background Technology

[0002] High-temperature furnaces, as a type of heating equipment, are mainly used for heating and heat treatment in laboratories and testing facilities of various industrial and mining enterprises and scientific research units. They are indispensable instruments and equipment in various laboratories. With the development of society, there are many types of high-temperature furnaces, among which high-temperature lifting furnaces are one type. Lifting furnaces are electric furnaces that can be lifted and lowered during use, and are an upgraded version of box furnaces and muffle furnaces.

[0003] In certain special circumstances, such as when cleaning the furnace or performing equipment maintenance, the furnace top needs to be raised to allow for internal operations. Raising the furnace top requires the use of hoisting equipment. Currently, the furnace top is generally hoisted using hooks and cranes. However, this hoisting method makes the furnace unstable during the hoisting process. After the furnace top is hoisted, workers need to manually position and lower the furnace top and furnace body before the furnace top can be installed and fixed. This process is cumbersome and increases the workload of workers. In addition, there are certain operational risks involved in the process of hoisting the furnace top. Summary of the Invention

An insertion block is inserted into the insertion groove. The end of the insertion block away from the clamping block is connected to the other movable rod.

[0011] Preferably, a second electric telescopic rod is embedded in the bottom of the lifting rod, with the telescopic end of the second electric telescopic rod facing downwards. The telescopic end of the second electric telescopic rod is connected to the top of the fifth fixed rod. An eighth sliding groove is horizontally opened at the bottom of the fifth fixed rod along its length direction. An eighth electric slider is installed at the top of the movable rod and is slidably installed inside the eighth sliding groove.

[0012] Preferably, the auxiliary mechanism includes a fourth fixed rod, a connector, and a connecting block. Multiple fourth fixed rods are movably and evenly installed on the bottom of the second fixed plate. A connector is movably installed on the bottom of the fourth fixed rod. A connecting block is rotatably installed inside the connector. A rotary motor is installed on the side wall of the connector. The output end of the rotary motor movably passes through the side wall of the connector and is connected to the connecting block.

[0013] Preferably, the bottom of the second fixing plate is provided with an annular groove, the top of the fourth fixing rod is provided with a third fixing rod, the bottom of the third fixing rod is provided with a fourth groove horizontally along the length of the third fixing rod, the top of the fourth fixing rod is provided with a fourth electric slider, the fourth electric slider is slidably installed inside the fourth groove, the top of the third fixing rod is provided with a third electric slider, the third electric slider is slidably installed inside the annular groove, and the bottom of the fourth fixing rod is embedded with a first electric telescopic rod, the telescopic end of the first electric telescopic rod faces downward, and the telescopic end of the first electric telescopic rod is connected to the connecting piece.

[0014] Preferably, a first slot is provided on one side of the connecting block, and a seventh sliding groove is provided on both sides of the first slot. A cleaning brush is slidably installed inside the first slot, and a seventh electric slider is installed on the side of the cleaning brush near the first sliding groove. The seventh electric slider is slidably installed inside the seventh sliding groove.

[0015] Preferably, the bottom of the connecting block has a second slot, a movable block is slidably installed inside the second slot, a pressure sensor is installed at the top of the inner wall of the second slot, a spring telescopic rod is installed at the top of the movable block, and the telescopic end of the spring telescopic rod is connected to the pressure sensor.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this invention, by incorporating clamping blocks and connecting blocks, when the furnace top needs to be hoisted, the clamping blocks and connecting blocks secure the furnace top lifting ring. Subsequently, the furnace top can be hoisted by raising the second fixing rod. During the hoisting process, the connecting blocks abut against the furnace top, thus securing it and making the furnace top more stable during hoisting, preventing positional shifts. When the furnace top needs to be reinstalled, it can be lowered directly, increasing the ease of use of the device, reducing the workload of workers, and the fully automatic operation also reduces the operational risks for workers.

[0018] This invention incorporates a movable block, a cleaning brush, and a pressure sensor. The cleaning brush abuts against the top of the lifting furnace, and a third electric slider slides in an annular groove, causing the cleaning brush to brush the furnace top. This prevents a large amount of dust from falling from the furnace top during hoisting and also performs daily cleaning and maintenance of the furnace top, increasing the ease of use of the device. When there are deposits on the furnace top that the cleaning brush cannot easily clean, the connecting block taps the furnace top, causing it to vibrate. The deposits on the furnace top vibrate under the vibration, reducing their adhesion and allowing the cleaning brush to clean the furnace top more easily, thus increasing the cleaning effectiveness of the device.

[0019] Before hoisting the furnace top, the movable block abuts against the furnace top, and the spring telescopic rod presses against the pressure sensor. At this time, the pressure sensor transmits the measured pressure value to the background control system. The background control system stores the pressure value measured by the pressure sensor when the lifting ring has not deformed, under the same abutment process of the movable block. The background control system compares the two pressure values. If the difference between the two exceeds the preset difference range, it indicates that the lifting ring has deformed. At this time, the staff should check the lifting ring and only hoist the furnace top after confirming that it is safe, so as to increase the safety of the equipment.

[0020] After the furnace top is lifted, the movable block abuts against the furnace top. At this time, the pressure sensor maintains the measuring state and has a stable pressure value. If the pressure value measured by the pressure sensor continues to decrease, it indicates that the furnace top is loose. At this time, by rotating the connecting block to a horizontal state and moving it below the furnace top, the connecting block provides additional support for the furnace top, thus completing the hoisting and reinforcement of the furnace top and increasing the safety of the device.

[0021] When installing the furnace top, the furnace top is pressed by the movable block. At this time, the pressure sensor measures the pressure value. The background control system compares the pressure values ​​measured by multiple pressure sensors. If the difference between multiple pressure values ​​exceeds the preset difference, it means that the furnace top is not placed in the furnace body. Then the staff can adjust the position of the furnace top. In this way, the placement of the furnace top can be detected, which increases the convenience of the staff for installing the furnace top.

[0022] After the furnace top and furnace body are in place, the furnace top is temporarily fixed by pressing it with connecting blocks. Then, when the staff installs the fixing bolts on the furnace top and furnace body, the furnace top will not shift in position, increasing the ease of use of the device.

[0023] During the operation of the lifting furnace, the connecting block moves to the top of the furnace according to the preset process. At this time, the pressure sensor measures the pressure value and transmits it to the background control system. The background control system compares the pressure value at this time with the preset standard pressure value. If the pressure difference exceeds the difference range, it indicates that the furnace top has deformed. At this time, the staff should immediately inspect the furnace top so that the device can detect the status of the furnace top and increase the ease of use of the device. Attached Figure Description

[0034] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The bottom of the second fixing plate 8 is equipped with a clamping mechanism and an auxiliary mechanism. The clamping mechanism allows the device to clamp the furnace top, and the lifting of the furnace top is completed by raising the second fixing rod 7.

[0036] As a technical optimization of the present invention, a first sliding groove 2 is horizontally formed on the top of the first fixing plate 1 along its length direction, and a first electric slider 3 is installed at the bottom of the first fixing rod 4. The first electric slider 3 is slidably installed inside the first sliding groove 2. By moving the first electric slider 3 in the first sliding groove 2, the first fixing rod 4 can be moved according to usage requirements.

[0037] As a technical optimization of the present invention, a second sliding groove 5 is vertically formed on one side of the first fixed rod 4 along its length direction. A second electric slider 6 is installed on the end of the second fixed rod 7 near the first fixed rod 4, and the second electric slider 6 is slidably installed inside the second sliding groove 5. By moving the second electric slider 6 in the second sliding groove 5, the second fixed rod 7 can be moved according to usage requirements.

[0038] As a technical optimization of the present invention, a fifth sliding groove 19 is horizontally formed at the bottom of the second fixing rod 7 along its length direction, and a fifth electric slider 20 is installed on the top of the second fixing plate 8. The fifth electric slider 20 is slidably installed inside the fifth sliding groove 19. The sliding of the fifth electric slider 20 in the fifth sliding groove 19 allows the second fixing plate 8 to move according to usage requirements.

[0039] As a technical optimization of the present invention, the clamping mechanism includes a lifting rod 31, a fifth fixed rod 32, and a movable rod 35. The lifting rod 31 is installed at the bottom center of the second fixed plate 8. The fifth fixed rod 32 is movably installed at the bottom end of the lifting rod 31. Two movable rods 35 are movably installed at the bottom of the fifth fixed rod 32. A clamping block 36 is installed on the bottom side of one movable rod 35 near the other movable rod 35. An insertion groove 37 is opened at the end of the clamping block 36 away from the installed movable rod 35. An insertion block 38 is inserted into the insertion groove 37. The end of the insertion block 38 away from the clamping block 36 is connected to the other movable rod 35. By sliding the eighth electric slider 34 in the eighth sliding groove 33, the insertion block 38 moves closer to the clamping block 36. When the insertion block 38 is inserted into the insertion groove 37, the clamping of the lifting ring is completed. At this time, the lifting of the furnace top can be completed by the retraction of the second electric telescopic rod 39 and the rise of the second fixed rod 7.

[0040] As a technical optimization of the present invention, a second electric telescopic rod 39 is embedded in the bottom of the lifting rod 31, with the telescopic end of the second electric telescopic rod 39 facing downwards. The telescopic end of the second electric telescopic rod 39 is connected to the top of the fifth fixed rod 32. An eighth sliding groove 33 is horizontally formed at the bottom of the fifth fixed rod 32 along its length. An eighth electric slider 34 is installed on the top of the movable rod 35 and is slidably installed inside the eighth sliding groove 33. By extending and retracting the second electric telescopic rod 39, the fifth fixed rod 32 can be extended to different positions according to different usage needs. The eighth electric slider 34 slides in the eighth sliding groove 33, allowing the movable rod 35 to move, thereby completing the clamping of the lifting ring.

[0041] As a technical optimization of the present invention, the auxiliary mechanism includes a fourth fixing rod 14, a connecting member 15, and a connecting block 17. Multiple fourth fixing rods 14 are movably and evenly installed on the bottom of the second fixing plate 8. A connecting member 15 is movably installed on the bottom of each fourth fixing rod 14. A connecting block 17 is rotatably installed inside the connecting member 15. A rotary motor 16 is installed on the side wall of the connecting member 15. The output end of the rotary motor 16 movably passes through the side wall of the connecting member 15 and is connected to the connecting block 17. The rotary motor 16 can drive the connecting block 17 to rotate, facilitating its switching between different usage states according to different usage requirements.

[0042] As a technical optimization of the present invention, the bottom of the second fixing plate 8 is provided with an annular groove 10, the top of the fourth fixing rod 14 is provided with a third fixing rod 9, the bottom of the third fixing rod 9 is provided with a fourth groove 12 horizontally along the length direction of the third fixing rod 9, the top of the fourth fixing rod 14 is provided with a fourth electric slider 13, the fourth electric slider 13 is slidably installed inside the fourth groove 12, the top of the third fixing rod 9 is provided with a third electric slider 11, the third electric slider 11 is slidably installed inside the annular groove 10, the bottom of the fourth fixing rod 14 is embedded with a first electric telescopic rod 24, the telescopic end of the first electric telescopic rod 24 faces downward, and the telescopic end of the first electric telescopic rod 24 is connected to the connecting member 15. The sliding of the third electric slider 11 in the annular groove 10 allows the connecting block 17 to rotate above the furnace top, facilitating the cleaning brush 27 to clean the furnace top. The first electric telescopic rod 24 can extend the connecting block 17. By extending and retracting the connecting block 17 through the first electric telescopic rod 24, the connecting block 17 strikes the furnace top of the lifting furnace, causing the furnace top to vibrate. At this time, the adhering material on the furnace top will vibrate under the vibration of the furnace top, reducing the adhesion of the adhering material, making it easier for the cleaning brush 27 to clean the furnace top, and increasing the cleaning degree of the device on the furnace top.

[0043] As a technical optimization of the present invention, a first slot 23 is provided on one side of the connecting block 17, and a seventh sliding groove 25 is horizontally provided on both sides of the first slot 23. A cleaning brush 27 is slidably installed inside the first slot 23, and a seventh electric slider 26 is installed on the side of the cleaning brush 27 near the first sliding groove 25. The seventh electric slider 26 is slidably installed inside the seventh sliding groove 25. The connecting block 17 rotates until the cleaning brush 27 faces the top of the lifting furnace. At this time, the seventh electric slider 26 slides in the seventh sliding groove 25, causing the cleaning brush 27 to move out of the first slot 23. Then, the first electric telescopic rod 24 drives the connecting piece 15 to extend, causing the connecting block 17 to move closer to the top of the lifting furnace until the cleaning brush 27 abuts against the top of the lifting furnace. At this time, the third electric slider 11 slides in the annular sliding groove 10, causing the cleaning brush 27 to brush the top of the lifting furnace.

[0044] As a technical optimization of the present invention, a second slot 28 is provided at the bottom of the connecting block 17. A movable block 18 is slidably installed inside the second slot 28. A pressure sensor 29 is installed at the top of the inner wall of the second slot 28. A spring telescopic rod 30 is installed at the top of the movable block 18, and the telescopic end of the spring telescopic rod 30 is connected to the pressure sensor 29. The movable block 18 abuts against the furnace top, which can complete the deformation detection of the furnace top. During the hoisting of the furnace top, the hoisting stability of the furnace top can be detected. During the installation of the furnace top, the installation position of the furnace top and the furnace body can be detected to prevent the furnace top and the furnace body from tilting, which would affect the installation of the furnace top and the furnace body. During the hoisting of the furnace top, the deformation of the lifting ring can be detected, which increases the safety of the device.

[0045] When using this invention, the electric drive mechanism used in this device can be controlled by the preset control system on the device. When using this device, the operator moves the first fixing plate 1 to the ground behind the lifting furnace and places the device stably. After the device is installed, the second fixing plate 8 and its installed mechanism are located above the top of the lifting furnace. The top of the lifting furnace is equipped with a lifting ring for hoisting. The lifting ring is a mature existing technology, so it will not be described in detail here.

[0046] When the furnace top needs to be hoisted, the rotating motor 16 drives the connecting block 17 to rotate until the cleaning brush 27 faces the furnace top. At this time, the seventh electric slider 26 slides in the seventh slide groove 25, causing the cleaning brush 27 to move out of the first slot 23. Then, the first electric telescopic rod 24 drives the connecting piece 15 to extend, causing the connecting block 17 to move closer to the furnace top until the cleaning brush 27 touches the furnace top. At this time, the third electric slider 11 slides in the annular slide groove 10, causing the cleaning brush 27 to brush the furnace top.

[0047] The first electric slider 3 slides in the first slide groove 2, allowing the first fixed rod 4 to move on the outside of the lifting furnace. The second fixed plate 8 moves on the top of the lifting furnace by sliding the fifth electric slider 20 in the fifth slide groove 19. This allows the cleaning brush 27 to thoroughly clean the top of the lifting furnace, increasing the ease of use of the device. When there are deposits on the top of the lifting furnace that the cleaning brush 27 cannot clean, the rotating motor 16 drives the connecting block 17 to rotate, causing the movable block 18 to rotate upwards. At this time, the first electric telescopic rod 24 drives the connecting block 17 to extend and retract. The connecting block 17 then taps the top of the lifting furnace, causing it to vibrate. The deposits on the top of the lifting furnace will vibrate under the vibration, reducing their adhesion and making it easier for the cleaning brush 27 to clean the top. This increases the cleanliness of the top and prevents dust and impurities from falling into the furnace body after the top is hoisted.

[0048] The workers unscrewed the fixing bolts between the furnace top and the furnace body, and then used the second electric telescopic rod 39 to drive the fifth fixing rod 32 to extend downwards until the fifth fixing rod 32 reached the lifting ring on the furnace top. At this time, the eighth electric slider 34 slids in the eighth sliding groove 33, causing the plug block 38 to move closer to the clamping block 36. When the plug block 38 is inserted into the plug groove 37, the lifting ring is clamped. At this time, the furnace top of the lifting furnace can be hoisted by the retraction of the second electric telescopic rod 39 and the rise of the second fixing rod 7.

[0049] Before hoisting the furnace top, after the lifting ring is clamped and fixed, the connecting piece 15 extends downwards. After the connecting piece 15 extends to the preset process, the movable block 18 abuts against the furnace top, and the spring telescopic rod 30 presses against the pressure sensor 29. At this time, the pressure sensor 29 transmits the measured pressure value to the background control system. The background control system stores the pressure value measured by the pressure sensor 29 when the lifting ring is not deformed and the movable block 18 abuts against the same process. The background control system compares the two pressure values. If the difference between the two exceeds the preset difference range, it indicates that the lifting ring has deformed. At this time, the staff should check the lifting ring and ensure safety before hoisting the furnace top to increase the safety of the equipment.

[0050] After the furnace top is hoisted, the movable block 18 abuts against the furnace top. The abutment of the furnace top by the connecting block 17 ensures the furnace top remains level during hoisting and increases its stability. At this time, the pressure sensor 29 maintains a stable pressure value. If the pressure value measured by the pressure sensor 29 continuously decreases, it indicates that the furnace top hoisting has become loose. In this case, the connecting block 17 no longer abuts against the furnace top, and the fourth electric slider 13 slides in the fourth slide groove 12, causing the fourth fixed rod 14 to move away from the lifting rod 31. When the fourth fixed rod 14 moves to the outer edge of the furnace top, the connecting block 17 is rotated by the rotary motor 16, causing the connecting block 17 to rotate to a horizontal position. Then, the connecting block 17 is moved downward by the first electric telescopic rod 24. When the connecting block 17 moves to below the furnace top, the fourth fixed rod 14 moves closer to the furnace top. When it moves to the preset position, the first electric telescopic rod 24 moves the connecting block 17 upward until the connecting block 17 touches the bottom of the furnace top. At this time, the hoisting and reinforcement of the furnace top is completed, increasing the safety of the device.

[0051] When the furnace top needs to be reinstalled on the furnace body, the second fixing rod 7 moves downwards to reinstall the furnace top on top of the furnace body. After the furnace top and furnace body are positioned, the two movable rods 35 move away from each other and then the lifting ring is released. At this time, the first electric telescopic rod 24 drives the connecting block 17 to extend, so that the movable block 18 can press the furnace top. At this time, the pressure sensor 29 measures the pressure value. The background control system compares the pressure values ​​measured by multiple pressure sensors 29. If the difference between multiple pressure values ​​exceeds the preset difference, it means that the furnace top and furnace body are not positioned correctly. Then the staff can adjust the position of the furnace top. In this way, the placement of the furnace top can be detected, increasing the ease of use of the device.

[0052] After the furnace top and furnace body are placed, the furnace top is temporarily fixed by pressing it with connecting block 17. Then, when the staff installs the fixing bolts on the furnace top and furnace body, the furnace top will not shift in position, increasing the ease of use of the device.

[0053] During the operation of the lifting furnace, the connecting block 17 moves to the top of the furnace according to the preset process. At this time, the movable block 18 squeezes the spring telescopic rod 30, and the spring telescopic rod 30 squeezes the pressure sensor 29. The pressure sensor 29 measures the pressure value and transmits it to the background control system. The background control system compares the pressure value at this time with the preset standard pressure value. If the pressure value difference exceeds the difference range, it indicates that the furnace top has deformed. At this time, the staff should immediately check the furnace top so that the device can detect the state of the furnace top and increase the ease of use of the device.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
