Abstract
Description
Technical Field
[0001] The present application relates to the technical field of mechanical equipment, and in particular to a power-assisted lifting mechanism for a confined space. Background Art
[0002] The ampoule is heated in the crucible barrel of the swing furnace. When the material in the bottle is completely molten, the bottle needs to be taken out from the crucible barrel, and the removal direction needs to be vertically upward along the barrel wall. After the ampoule is completely taken out of the swing furnace, it needs to be transferred to a cold water truck for rapid cooling. At present, the fixture for clamping ampoules is a pneumatic clamp. Due to the large amount of high-temperature melt in the ampoule or crucible, the weight is heavy, plus the weight of the pneumatic clamp, the overall weight is relatively heavy, and the total length of the bottle is relatively long. At this time, it is also required to lift the bottle vertically upward when taking out the ampoule, and the bottle must not shake much during transfer, so it is more difficult for employees to lift and transfer the bottle. In addition, an exhaust duct is installed above the swing furnace, and the distance between the exhaust duct opening and the upper surface of the swing furnace is approximately between 700-800 mm. The length of the ampoule bottle is between 300-380 mm, which limits the internal working space. Therefore, the ordinary pneumatic power-assisted lifting mechanism cannot be used. For this reason, the utility model proposes a power-assisted lifting mechanism for a confined space. Utility Model Content
[0003] The embodiment of the present application provides a power-assisted lifting mechanism for a confined space, which enables lifting operations to be performed in a confined and narrow space. The ampoule bottle can be vertically lifted out of the crucible barrel, and the ampoule bottle can also be freely rotated to achieve horizontal transportation of the bottle body.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0031] This application provides an embodiment of a power-assisted lifting mechanism for a confined space. For details, please refer to Figure 1 .
[0032] The power-assisted lifting mechanism for confined space in this embodiment includes: a supporting structure, a horizontal rotating mechanism 4 is arranged on the top of the supporting structure, a column 5 is fixedly arranged on the top of the horizontal rotating mechanism 4, a cross bar 8 is connected to the top of the column 5 for rotation in the vertical direction, a first driving device for driving the cross bar 8 to perform pitch motion is arranged on the column 5, a pulley assembly 11 and a second driving device are arranged on the cross bar 8, and a suspension rope is connected to the output end of the second driving device for controlling the extension and retraction of the suspension rope; the suspension rope is connected to a clamping mechanism through the pulley assembly 11.
[0033] It should be noted that the power-assisted lifting mechanism for confined space has a simple structure and is easy to use, and can well solve the problem of power-assisted lifting of heavy objects in a small space or a space with limited conditions. Through the cooperation of the second drive device, the suspension rope and the pulley assembly 11, the ampoule can be lifted out of the crucible barrel in the vertical direction, and at the same time, the horizontal rotating mechanism 4 can be used to achieve free rotation, and the high-temperature ampoule can be turned out of the narrow space. In addition, since the height of the cold water truck is lower than the swing furnace, the present application sets a first drive device, and uses the first drive device to drive the cross bar 8 to perform a pitching motion, which can be lowered twice, thereby facilitating the high-temperature ampoule to be placed in the cold water truck.
[0034] The above is an embodiment of a power-assisted lifting mechanism for a confined space provided in the embodiment of the present application. The following is an embodiment of a power-assisted lifting mechanism for a confined space provided in the embodiment of the present application. For details, please refer to Figure 1 .
[0035] The power-assisted lifting mechanism for confined space in this embodiment includes: a support structure, a horizontal rotation mechanism 4 is arranged on the top of the support structure, a column 5 is fixedly arranged on the top of the horizontal rotation mechanism 4, a cross bar 8 is connected to the top of the column 5 in a vertical rotation direction, a first driving device for driving the cross bar 8 to perform pitching movement is arranged on the column 5, a pulley assembly 11 and a second driving device are arranged at the bottom of the cross bar 8, a suspension rope is connected to the output end of the second driving device for controlling the extension and retraction of the suspension rope; the suspension rope is connected to a clamping mechanism through the pulley assembly 11. Specifically, the clamping mechanism can be a pneumatic clamp 12.
[0036] It should be noted that: this power-assisted lifting mechanism can be used in smaller spaces or spaces with restricted conditions. In terms of vertical lifting, it can easily help employees lift heavier objects, and the lifting stability will not produce greater shaking compared to existing large-scale power-assisted lifting mechanisms.
[0037] The output end of the second driving device is connected to the suspension rope via a slider 13, and the slider 13 is slidably connected to the crossbar 8. It can be understood that by providing the slider 13, the suspension rope can be made more stable during movement.
[0038] The second driving device can be a pen-shaped cylinder 9, which saves space and can ensure a larger stroke, and is simple to combine and has lower cost. The telescopic movement of the pen-shaped cylinder 9 drives the rope to move on the pulley assembly 11, thereby realizing the vertical up and down movement of the clamping mechanism.
[0039] Specifically, a mounting platform 6 is fixedly disposed at the lower portion of the column 5 , and the first driving device is disposed on the mounting platform 6 .
[0040] The mounting platform 6 is provided with a first manual valve for controlling the first driving device and a second manual valve for controlling the second driving device.
[0041] The first driving device is a telescopic cylinder 7 , and the output end of the telescopic cylinder 7 is hinged to the tail end of the cross bar 8 .
[0042] It should be noted that the movement of the telescopic cylinder 7 and the pen-shaped cylinder 9 is controlled by the first manual valve and the second manual valve. Only compressed air is required without external power supply. Compared with the current large-scale lifting mechanism, it is more flexible to use and can be easily moved to any position.
[0043] Preferably, the pulley assembly 11 is arranged at the head end of the cross bar 8 .
[0044] The supporting structure includes a supporting column 1 and a base plate 2 arranged at the bottom of the supporting column 1 .
[0045] The bottom of the base plate 2 may be provided with moving wheels to facilitate the movement of the power-assisted lifting mechanism. Specifically, the moving wheels may be universal wheels 3, which are more convenient for movement in a narrow space.
[0046] The lifting rope can be a steel wire lifting rope 10 .
[0047] In the specific implementation, a quartz ampoule with an inner diameter of 100 mm and a wall thickness of 4 mm was used as a reaction and containing container for the reaction of the components As 40 Se 60When melting the chalcogenide glass, high-purity As and high-purity Se with a purity of 5N were used as raw materials. As was accurately weighed as 1162.4g and Se was as high as 1837.6g in the glove box. The weight of the quartz ampoule was 2503g. The quartz ampoule containing the raw materials was vacuum-evacuated and sealed with hydrogen-oxygen flame in turn. The ampoule was then transferred to a rocking furnace, slowly heated from room temperature to 900°C, and then kept warm for high-temperature rocking melting and homogenization. After high-temperature melting for 10 hours, the temperature was lowered to When the temperature is 400℃, the furnace door is opened. At this time, the power-assisted lifting mechanism is moved to the top of the furnace body. Before taking out of the furnace, the pneumatic clamp 12, the telescopic cylinder 7 and the pen-shaped cylinder 9 are all connected to compressed air. The air inlet pressure is 0.6Mpa. The manual valve of the pneumatic clamp 12 is opened to open the pneumatic clamp 12. The pneumatic clamp 12 is transferred to the top of the quartz ampoule to be taken out of the furnace. The second manual valve is opened. At this time, the pen-shaped cylinder 9 extends out, and the pneumatic clamp 12 is slowly lowered until the quartz ampoule to be clamped is After the top of the ampoule is flush with the root of the pneumatic clamp 12, the manual valve of the pneumatic clamp 12 is closed. Under the action of the cylinder, the pneumatic clamp 12 is tightened inward until it contacts and clamps the outer diameter of the quartz tube ampoule. After the pneumatic clamp 12 stops moving, the second manual valve is closed. At this time, the pen-shaped cylinder 9 shrinks and resets, and the high-temperature ampoule is moved out of the heating furnace (the pulling force of the pen-shaped cylinder 9 back to the origin is roughly equal to the gravity of the heavy object (including the ampoule, the material in the molten state, and the clamping mechanism). The operator only needs to grab the pneumatic gripper 12 and gently lift it up to lift the item out), then transfer the ampoule bottle to the top of the quenching liquid through the horizontal rotating mechanism 4, open the pen-shaped cylinder 9 and the telescopic cylinder 7, and let the ampoule bottle drop into the quenching liquid for quenching treatment. The temperature of the quenching liquid is 50℃ warm water, and the quenching time is 5min. After the quenching is completed, the quartz tube is transferred to the annealing furnace, and after being kept at 180℃ for 3h, it is cooled to room temperature at a cooling rate of 3℃ / h. After the annealing is completed, the stripe degree of the obtained chalcogenide glass rod material is tested to be A level.
[0048] A quartz ampoule with an inner diameter of 80 mm and a wall thickness of 3.5 mm was used as a reaction and holding container for the Ge 33 As 12 Se 55When melting the chalcogenide glass, high-purity As, high-purity Se and high-purity Ge with a purity of 5N were used as raw materials. 235.4 g As, 1137 g Se and 627.6 g Ge were accurately weighed in the glove box. g, the weight of the quartz ampoule is 2503g. The quartz ampoule containing the raw materials is vacuum-drawn and sealed with a hydrogen-oxygen flame in turn, and then the ampoule is transferred to a swing furnace, slowly raised from room temperature to 950℃, and then kept warm for high-temperature swing melting and homogenization treatment. After high-temperature melting for 15 hours, the furnace door is opened when the temperature drops to 550℃. At this time, the power-assisted lifting mechanism is moved to the top of the furnace body. Before taking out of the furnace, the pneumatic clamp 12, the telescopic cylinder 7 and the pen-shaped cylinder 9 are all connected to compressed air, and the air inlet pressure value is 0.6Mpa. The manual valve of the pneumatic clamp 12 is opened to open the pneumatic clamp 12, and the pneumatic clamp 12 is transferred to the top of the quartz ampoule to be taken out of the furnace. The second manual valve is opened, and the pen-shaped cylinder 9 is extended at this time. The pneumatic clamp 12 is slowly lowered straight When the top of the quartz ampoule to be clamped is flush with the root of the pneumatic clamp 12, the manual valve of the pneumatic clamp 12 is closed. Under the action of the cylinder, the pneumatic clamp 12 is tightened inward until it contacts and clamps the outer diameter of the quartz tube ampoule. When the pneumatic clamp 12 no longer moves, the second manual valve is closed. At this time, the pen-shaped cylinder 9 shrinks and resets, and the high-temperature ampoule is moved out of the heating furnace. Then, the ampoule is transferred to the top of the quenching liquid through the horizontal rotating mechanism 4, and the pen-shaped cylinder 9 and the telescopic cylinder 7 are opened to make the ampoule drop into the quenching liquid for quenching treatment. The temperature of the quenching liquid is 50°C warm water, and the quenching time is 5min. After the quenching is completed, the quartz tube is transferred to the annealing furnace, and after being kept at 350°C for 5h, it is cooled to room temperature at a cooling rate of 3°C / h. After the annealing is completed, the stripe degree of the obtained chalcogenide glass rod material is tested to be B grade.
