Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermocouples, in particular to a thermocouple position fixing device suitable for concrete beam temperature field test. Background Art
[0002] A thermocouple refers to a temperature measuring element in a temperature measuring instrument. It directly measures temperature and converts the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium through an electrical instrument. It is usually composed of a thermoelectrode, an insulating sleeve protection tube, a junction box and other main parts. In the field of thermocouple temperature measurement experiments, in the process of conducting concrete beam temperature field experiments, when studying the temperature field inside the concrete beam, it is necessary to drill holes on the side of the beam mold before pouring the concrete beam, and then insert the thermocouple through the hole to collect the temperature. In the process of pouring the concrete beam, in order to ensure that the position of the thermocouple does not shift and reduce the impact of vibration on the position of the thermocouple, the position of the thermocouple must be fixed. Therefore, a thermocouple position fixing device suitable for concrete beam temperature field tests is required.
[0003] However, in the prior art, in the temperature field experiment of concrete beams, nylon ropes and wooden boards are generally used to fix thermocouples. Both of them directly fix the thermocouples by fixing the thermocouples with the thermoelectrodes. Since the temperature of the thermoelectrodes is usually very high during the temperature field test, and the thermocouples are not fixed by the concrete slabs, and the thermocouples are not indirectly fixed by the protective tubes for fixing the thermocouples, this will affect the test results, and the test position of the thermocouples may deviate, thereby reducing the accuracy of the fixed thermocouple position. In addition, in the prior art, since the height of the thermocouples is generally fixed when they are fixed, they can only fix thermocouples with a single arrangement height, which makes it impossible to fix thermocouples with different arrangement heights, thereby reducing its scope of application.

[0028] When in use, one end of the mounting screw 13 is located inside the mounting block 11, the screw rod 6 is threadedly connected to the first thread groove 36, the second fixing tube 35 and the second limiting column 33 are both located in the connecting long groove 39, and one end of the limiting long plate 30 is located in a first limiting long groove 12. Before pouring a concrete beam, when it is necessary to use this device to fix a thermocouple, move this device to the ground where a concrete beam temperature field experiment is conducted, move the concrete slab body 41, and put the concrete slab body 41 into the concrete beam mold body 40. The concrete slab body 41 is bonded to the inside of the concrete beam mold body 40 through the concrete, and the thermocouple insertion hole on the concrete slab body 40 corresponds to the thermocouple insertion hole on the concrete slab body 41, so that the mounting The mounting hole 4 corresponds to the thermocouple insertion hole on the concrete beam mold body 40 and the mounting hole 4 is located on the right side of the concrete beam mold body 40. The four mounting screws 13 are rotated at the same time to rotate one end of the mounting screw 13 and insert it into the ground. When one end of the mounting screw 13 is completely inserted into the ground, the four mounting screws 13 are stopped from rotating and the thermocouple is moved. First, the thermocouple is inserted into the mounting hole 4, and then the thermocouple is passed out from the thermocouple insertion hole on the concrete beam mold body 40. Then, the thermocouple is inserted into the thermocouple insertion hole on the concrete slab body 41. When the electric heating pole of the thermocouple passes out from the mounting hole 4 and the protective tube of the thermocouple is located inside the mounting hole 4, the two screws 6 are rotated at the same time to make the screws 6 and the first thread groove 36 is disconnected and one end of the screw rod 6 is located inside the limiting square plate 18, the supporting cross plate 17 is rotated to make the supporting cross plate 17 rotate along the outer annular groove 22, the sector ring 5 rotates along the inner annular groove 20, and the limiting square plate 18 rotates along the column box 3, so that the supporting cylinder 31 rotates along the column box 3 and the first fixed cylinder 21 respectively.

The second fixing tube 35 is moved to make the limiting cross bar 32 slide along the second limiting long groove 38. When the second fixing tube 35 slides to the maximum distance, the second fixing tube 35 contacts the first fixing tube 21, and the rotation of the holding column 15 stops. At this time, the first limiting column 19 squeezes the protection tube of the thermocouple, causing the first limiting column 19 to deform. Under the action of the first limiting column 19, the upper half of the protection tube of the thermocouple is compressed, and the protection tube of the thermocouple squeezes the connecting column 34, causing the connecting column 34 to deform. Under the action of the connecting column 34, the lower half of the protection tube of the thermocouple is compressed.

When it is necessary to fix thermocouples arranged at different heights, the two holding plates 24 are moved away from the supporting cylinder 8 at the same time, so that the door-shaped plate 14 moves, the spring 28 is stretched, the limiting horizontal plate 27 and the limiting long rod 29 are both slid along the supporting cylinder 8, and the limiting long plate 30 is respectively slid along a first limiting long groove 12 and the supporting cylinder 8. When the limiting long plate 30 is disconnected from a first limiting long groove 12, the state of the two holding plates 24 is kept unchanged, and the supporting cylinder 8 is moved in the vertical direction so that the supporting cylinder 8 is respectively slid along the positioning vertical plate 9 and the supporting vertical plate 9. The plate 23 and the limit block 25 slide to make the connecting vertical plate 7 slide along the positioning vertical plate 9. When the height of the device is the height of the arranged thermocouple, and when the limit long plate 30 corresponds to the other first limit long groove 12, the state of the supporting long cylinder 8 is kept unchanged, the two holding plates 24 are released, and the spring 28 changes from a stretched state to a compressed state, so that the limit long plate 30 enters the other first limit long groove 12, and the supporting long cylinder 8 is released. At this time, the device can fix thermocouples with different arrangement heights. In this process, the height of the device can be changed, so that the device can fix thermocouples with different arrangement heights, so that the device can avoid narrowing the scope of application due to the inability to fix thermocouples with different arrangement heights, and the device has a wide range of application.
