Description

Technical Field

[0001] The utility model belongs to the technical field of creep endurance testing, in particular to a heating furnace replacement device for a creep endurance testing machine. Background Art

[0002] The creep endurance tester measures the endurance strength and creep performance of materials under a certain temperature and constant tensile load within a specified time. It simulates the deformation and destruction process of materials under high temperature and high stress conditions. It is widely used in aviation, energy, civil engineering and manufacturing industries. It is a common equipment for metallurgical departments, scientific research institutions, colleges and universities, and related factories and mines to conduct material performance inspection and research.

[0003] The creep endurance tester works at high temperature for a long time, and the heating body is prone to aging and often burns out. The power cord and terminal will also burn out or burn out due to current overload. In addition, the furnace lining material is also prone to breakage due to long-term use; therefore, when the heating furnace fails, it needs to be replaced in time. In some laboratories, due to the limitation of the operating space in the workplace or the layout of power line troughs on the ground, it is often necessary to manually support and replace the faulty heating furnace. Due to the large size and heavy weight of the heating furnace, the labor intensity of the staff is greatly increased, which reduces the maintenance efficiency of the test machine. Utility Model Content

[0025] The replacement device of the utility model includes a heating furnace supporting platform 8, a hand jack 9 and a jack platform 10. The jack platform 10 is installed on the column 1 of the creep endurance testing machine. The lower end of the hand jack 9 is welded to the jack platform 10. The upper end of the hand jack 9 is welded and fixed to the heating furnace supporting platform 8. The heating furnace supporting platform 8 is connected to the column 1 of the creep endurance testing machine through the upper quick-release clamp 4 so as to be relatively movably connected. The hand jack 9 drives the heating furnace supporting platform 8 to move up and down, and after moving into place, it abuts against the faulty heating furnace 7. After moving into place, the heating furnace supporting platform 8 is kept fixed to the column 1 of the creep endurance testing machine through the upper quick-release clamp 4.

[0026] In order to increase the moving stroke of the heating furnace supporting platform 8, the jack platform 10 of this embodiment is relatively movably connected to the creep endurance testing machine column 1 through the lower quick-release clamp 5, and remains fixed to the creep endurance testing machine column 1 after moving into position.

[0027] The heating furnace supporting platform 8 of this embodiment is detachably connected to the upper quick release clamp 4 by bolts 3, and the jack platform 10 is detachably connected to the lower quick release clamp 5 by bolts 3. Rubber pads 11 are provided between the inner surface of the upper quick release clamp 4 and the column 1 of the creep endurance test machine, and between the inner surface of the lower quick release clamp 5 and the column 1 of the creep endurance test machine.

[0029] The upper surface of the heating furnace supporting platform 8 of the present embodiment is provided with a circular shock-absorbing cushion 12 , and the material of the shock-absorbing cushion 12 is rubber.

[0030] The shape of the heating furnace supporting platform 8 in this embodiment is circular (diameter can be 25-40 mm), square (side length can be 25-40 mm) or rectangular (length can be 25-40 mm, width can be 25-40 mm), preferably circular, and the thickness can be 2-5 mm. The material of the heating furnace supporting platform 8 can be stainless steel or other carbon steel with a yield strength greater than 200 MPa, preferably stainless steel.

[0031] The working principle of the utility model is:

[0032] The utility model is installed on the column 1 of the creep endurance test machine through a quick-release clamp, and the heating furnace supporting platform 8 is adjusted up and down by a hand-cranked jack 9 to the position of supporting the heating furnace 7 that has a fault, the heating furnace suspension arm latch 6 is removed, and the hand-cranked jack 9 is adjusted to lower the heating furnace supporting platform 8 to a suitable operating position. Specifically:

[0033] The utility model installs the heating furnace supporting platform 8 on the column 1 of the creep endurance test machine through the upper quick release clamp 4, and installs the jack platform 10 on the column 1 of the creep endurance test machine through the lower quick release clamp 5. After adjusting the jack platform 10 to the set height, lock the lower quick release clamp 5 to keep it fixed with the column 1 of the creep endurance test machine, so as to keep the jack platform 10 fixed with the column 1 of the creep endurance test machine. Use the hand-cranked jack 9 to raise the heating furnace supporting platform 8 to the bottom of the heating furnace 7 that needs to be replaced and has a fault, close to the bottom of the heating furnace 7; adjust the heating furnace suspension arm 2 to align the heating furnace 7 with the center of the heating furnace supporting platform 8, and then shake the hand-cranked jack 9 to make the heating furnace supporting platform 8 support the heating furnace 7, and lock the upper quick release clamp 4 to keep it fixed with the column 1 of the creep endurance test machine. After confirming that the whole replacement device is stable, remove the heating furnace suspension arm latch 6 between the heating furnace 7 and the other side of the second suspension arm 202, and adjust the position of the heating furnace 7 while removing the heating furnace suspension arm latch 6, so that the heating furnace 7 falls stably on the center of the heating furnace support platform 8. After confirming that the whole replacement device is stable and firm again, open the upper quick release clamp 4, so that the upper quick release clamp 4 and the creep endurance test machine column 1 can move relative to each other, adjust the hand jack 9 to lower the heating furnace support platform 8 to a suitable operating position, lock the upper quick release clamp 4 to keep it fixed with the creep endurance test machine column 1, and move the heating furnace 7 that needs to be replaced and has a fault out of the operating space. Finally, move the new heating furnace 7 to the heating furnace supporting platform 8, open the upper quick-release clamp 4, adjust the heating furnace supporting platform 8 to the position of the heating furnace suspension arm 2 through the hand-cranked jack 9, lock the upper quick-release clamp 4 to keep it fixed with the creep endurance testing machine column 1, adjust the heating furnace suspension arm 2, and insert the heating furnace suspension arm latch 6 to complete the replacement of the faulty heating furnace 7.
