Description

Technical Field

[0001] This utility model belongs to the technical field of creep testing devices, specifically relating to a bolt creep testing device. Background Technology

[0002] Creep testing is an experimental method used to evaluate the deformation behavior of materials under prolonged stress. It is primarily used to study the deformation properties of materials under high temperature and sustained stress environments, particularly stress relaxation or plastic deformation that may occur in engineering structures. In creep testing, material samples are typically subjected to a constant stress or strain while the temperature is maintained at a high level. By monitoring and recording the deformation of the material over a period of time, the creep behavior can be determined, such as creep rate, creep retardation time, and creep life. Creep testing is crucial for evaluating the stability and reliability of materials under high temperature and sustained stress environments.

[0003] Bolt creep tests are generally conducted using a creep testing machine. Existing creep testing machines are equipped with a heating furnace. The bolt specimen is fixed inside the heating furnace by a clamp between the upper and lower pull rods. After the test, the staff opens the heating furnace and takes out the bolt specimen. Because the temperature inside the heating furnace is very high after the test, the staff needs to wait for a certain period of time before opening the heating furnace, and they may still be burned by the high temperature inside the heating furnace. Utility Model Content

[0004] The purpose of this invention is to provide a bolt creep testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bolt creep testing device, comprising a body, a heating mechanism, and a cooling mechanism. The body includes a base, a top base, and a support column fixedly installed between the base and the top base. The heating mechanism includes two semi-circular heating furnace bodies. A support plate is fixedly installed between two adjacent support columns. An electric push rod is fixedly installed on the support plate, and one end of the electric push rod is fixedly connected to the semi-circular heating furnace body.

[0006] The cooling mechanism includes an air outlet pipe fixedly connected between the base and the top base. Several air outlet nozzles are provided on the side of the air outlet pipe near the semi-circular heating furnace body. A water tank is fixedly installed on one side of the base, and a blower is fixedly installed on one side of the water tank. A heat exchange tube is fixedly connected to the outlet end of the blower. The heat exchange tube passes through the water tank, and the end of the heat exchange tube away from the blower is connected to the air outlet pipe.

[0007] In a preferred embodiment, both ends of the support plate are fixedly connected to mounting sleeves, which are then fixedly mounted on the support column by bolts.

[0008] In a preferred embodiment, a filter screen is fixedly connected inside the air outlet.

[0009] In a preferred embodiment, the heat exchange tubes are arranged in an S-shape inside the water tank.

[0010] In a preferred embodiment, a cooling component is provided on one side of the water tank.

[0011] In a preferred embodiment, the cooling assembly includes a heat dissipation plate fixedly connected to the outer wall of the water tank, a plurality of heat conduction pipes extending into the water tank being fixedly connected to one side of the heat dissipation plate, cooling fins being fixedly connected to the surface of the heat dissipation plate, and a radiator being fixedly installed on the surface of the cooling fins.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This bolt creep testing device, through the setting of the heating mechanism, can activate the electric push rod to retract after the test, so that the electric push rod drives the two semi-arc heating furnace bodies to separate, without the need to manually open the heating furnace, reducing the risk of burns when opening the furnace;

[0014] This bolt creep testing device, through the setting of a cooling mechanism, allows the blower to be started to blow air into the heat exchange tubes after the two semi-circular heating furnace bodies are separated. When the air in the heat exchange tubes passes through the water tank, the water in the tank can cool the air in the heat exchange tubes to a certain extent. The low-temperature air enters the air outlet pipe through the heat exchange tubes and blows onto the bolt sample from the air outlet nozzle of the air outlet pipe, rapidly cooling the bolt sample, reducing waiting time, and avoiding high-temperature burns.

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-5 This utility model provides a bolt creep testing device, including a body 1, a heating mechanism 2, and a cooling mechanism 3. The body 1 includes a base 11, a top seat 12, and a support column 13 fixedly installed between the base 11 and the top seat 12. A pull rod 14 is provided at the top of the base 11, and an upper pull rod 15 is provided at the bottom of the top seat 12. Clamps 16 are provided at the ends of both the pull rod 14 and the upper pull rod 15. The heating mechanism 2 includes two semi-circular heating furnace bodies 21. A support plate 22 is fixedly installed between two adjacent support columns 13. An electric push rod 23 is fixedly installed on the support plate 22. One end of the electric push rod 23 is fixedly connected to the semi-circular heating furnace body 21. Mounting sleeves 24 are fixedly connected to both ends of the support plate 22 by bolts. The mounting sleeve 24 is fixed on the support column 13. With the heating mechanism 2, during use, the bolts of the mounting sleeve 24 are loosened, the mounting sleeve 24 is slid along the support column 13, the semi-circular heating furnace body 21 is moved to a suitable height, and then the bolts are tightened to fix the mounting sleeve 24. During the test, the two ends of the bolt are fixed by the clamps 16 on the pull rod 14 and the pull rod 15 respectively. Then, the electric push rod 23 is activated to extend, so that the electric push rod 23 drives the two semi-circular heating furnace bodies 21 to close, so that the bolt sample can undergo a high-temperature creep test in the two semi-circular heating furnace bodies 21. After the test, the electric push rod 23 can be activated to retract, so that the electric push rod 23 drives the two semi-circular heating furnace bodies 21 to separate, without the need to manually open the heating furnace.

[0024] Reference Figures 1-3The cooling mechanism 3 includes an air outlet pipe 31 fixedly connected between the base 11 and the top seat 12. Several air outlet nozzles 32 are provided on the side of the air outlet pipe 31 near the semi-circular heating furnace body 21. A water tank 33 is fixedly installed on one side of the base 11, and a blower 34 is fixedly installed on one side of the water tank 33. A heat exchange tube 35 is fixedly connected to the outlet end of the blower 34. The heat exchange tube 35 passes through the water tank 33 and is arranged in an S-shape within the water tank 33. The end of the heat exchange tube 35 furthest from the blower 34 is connected to the air outlet. With the connection of pipe 31 and the setting of cooling mechanism 3, after the two semi-arc heating furnace bodies 21 are separated, the blower 34 can be started to blow air into the heat exchange tube 35. When the air in the heat exchange tube 35 passes through the water tank 33, the water in the water tank 33 can cool the air in the heat exchange tube 35 to a certain extent. The low temperature air enters the air outlet pipe 31 through the heat exchange tube 35 and blows from the air outlet nozzle 32 of the air outlet pipe 31 onto the bolt sample, which quickly cools the bolt sample, reduces the waiting time, and avoids high temperature burns.

[0025] The air outlet 32 ​​is internally connected to a filter 36, which prevents impurities from entering the air outlet 32.

[0026] Reference Figure 2 and Figure 4 A cooling assembly 37 is provided on one side of the water tank 33. The cooling assembly 37 includes a heat sink 371 fixedly connected to the outer wall of the water tank 33. Several heat conduction pipes 372 extending into the water tank 33 are fixedly connected to one side of the heat sink 371. A cooling chip 373, which is a semiconductor cooling chip, is fixedly connected to the surface of the heat sink 371. A radiator 374 is fixedly installed on the surface of the cooling chip 373. With the cooling assembly 37, during use, as the water temperature in the water tank 33 gradually rises, the cooling chip 373 and the radiator 374 can be activated. This allows the heat conduction pipes 372 to conduct the heat in the water tank 33 to the surface of the heat sink 371. The hot end of the cooling chip 373 absorbs the heat from the heat sink 371 and transfers the heat to the cold end of the cooling chip 373. The radiator 374 then dissipates the heat, thereby ensuring that the water in the water tank 33 is in a low-temperature environment.

[0027] The working principle and usage procedure of this utility model are as follows: First, during use, loosen the bolts securing the mounting sleeve 24, slide the mounting sleeve 24 along the support column 13, move the semi-circular heating furnace body 21 to a suitable height, and then tighten the bolts to fix the mounting sleeve 24. During the test, fix both ends of the bolt using the clamps 16 on the lower pull rod 14 and the upper pull rod 15, respectively. Then, activate the electric push rod 23 to extend, causing the electric push rod 23 to drive the two semi-circular heating furnace bodies 21 to close, allowing the bolt sample to undergo a high-temperature creep test within the two semi-circular heating furnace bodies 21. After the test, The electric push rod 23 can be activated to retract, causing the two semi-circular heating furnace bodies 21 to separate without manually opening the heating furnace. After the two semi-circular heating furnace bodies 21 separate, the blower 34 can be activated to blow air into the heat exchange tube 35. When the air in the heat exchange tube 35 passes through the water tank 33, the water in the water tank 33 can cool the air in the heat exchange tube 35 to a certain extent. The low-temperature air enters the air outlet 31 through the heat exchange tube 35 and is blown onto the bolt sample from the air outlet 32 ​​of the air outlet 31, which quickly cools the bolt sample, reduces waiting time, and avoids high-temperature burns.
