Technical Field

[0001] The utility model relates to the technical field of temperature detection auxiliary equipment, in particular to an auxiliary equipment for detecting abnormal temperature of gas turbine bearings. Background Technique

[0002] The gas turbine bearing is a crucial component in a gas turbine, responsible for supporting the rotor and ensuring its stability and reliability under high-temperature and high-speed operating conditions. During the production process of gas turbine bearings, high-temperature detection is required to test the bearings under high temperature. When abnormalities occur during the high-temperature detection of the bearings, they can be removed through auxiliary equipment for recycling, avoiding the use of inferior products and affecting the normal operation of the gas turbine. Nowadays, detection is usually carried out through auxiliary equipment, where an electric heating element is used to heat the outer surface of the bearing, and a thermocouple temperature sensor is used to complete the temperature detection.

[0003] However, most of the common auxiliary equipment for detecting abnormal temperature of gas turbine bearings is fixed during the detection process, and its detection structure and heating structure are both fixedly arranged, resulting in a reduction in heating efficiency and an uneven heating situation, affecting the accuracy of the detection results. In view of this, we propose an auxiliary equipment for detecting abnormal temperature of gas turbine bearings. Content of the Utility Model

[0006] Above the top wall of the workbench, there is a temperature detection component for facilitating the heating and temperature detection of the gas turbine bearing. The temperature detection component includes a first cylinder. The output end of the first cylinder is connected to a double-axis hinge. A perforated movable rod is sleeved on the vertical shaft of the double-axis hinge. A first rotating shaft is arranged in another opening of the perforated movable rod.

The output end of the motor is connected to a second rotating shaft. The bottom end of the second rotating shaft is connected to a turntable.

[0008] Preferably, a first rotation hole is opened on one side wall of the workbench. The support base is installed on one side wall of the workbench. The output end of the forward and reverse motor corresponds to the position of the first rotation hole.

[0009] Preferably, a second rotation hole is opened between the two first limit chutes. A groove is opened on the side wall of one of the limit chutes. A bearing is arranged in the groove.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects:

[0015] The utility model drives through a forward and reverse motor, enabling a bidirectional threaded rod to drive two threaded hole plates and arc-shaped chucks to move in opposite directions. Under the action of the arc surface of the arc-shaped chucks, the gas turbine bearing placed on the workbench is clamped and positioned. Then, the motor drives the second rotating shaft to drive the turntable to rotate, enabling the temperature detection component installed on the turntable to rotate. During the rotation process, the electric heating arc panel can uniformly heat the bearing, reducing the problem that uneven heating of the bearing affects the detection result. And under the rotation of the thermocouple temperature sensor, multi-site detection of the bearing is achieved, avoiding differences in the temperature of some structures of the bearing that are difficult to detect by a fixedly installed thermocouple temperature sensor, thereby improving the accuracy during detection. At the same time, driven by the first cylinder, the distance between the electric heating arc panel and the thermocouple temperature sensor can be adjusted in cooperation with the double-axis hinge, the perforated movable rod, the first rotating shaft and the anti-disengagement movable part, which is beneficial to applying gas turbine bearings of different diameters and facilitating subsequent detection work.

Detailed Description of the Embodiment

[0021] The following further describes the technical solution of the utility model in conjunction with the drawings and specific embodiments. Embodiment

[0022] As Figures 1-4As shown in the figure, an auxiliary device for detecting abnormal temperature of a gas turbine bearing proposed by the present utility model includes a workbench 1 with symmetrically arranged first limit chutes on its top wall. The support legs of the bracket 2 are fixedly connected to the top wall of the workbench 1, and the controller 3 is fixedly installed on the front-facing wall of the workbench 1. A clamping and limiting assembly 4 for facilitating the position limitation of the gas turbine bearing is installed on the workbench 1. The clamping and limiting assembly 4 includes a support seat 41, a forward and reverse motor 42, a bidirectional threaded rod 43, a threaded hole plate 44, and an arc-shaped chuck 45. The support seat 41 is fixedly installed on one side wall of the workbench 1. The position of the first rotation hole opened on one side wall of the workbench 1 corresponds to the position of the second rotation hole opened between the two first limit chutes. At the same time, the positions of the first rotation hole and the second rotation hole also correspond to the position of the groove opened on the side wall of one first limit chute. The bearing arranged in the groove is sleeved on the outer surface of the bidirectional threaded rod 43. The end of the bidirectional threaded rod 43 passes through the second rotation hole and the first rotation hole, so that its end is connected to the output end of the forward and reverse motor 42, which is beneficial to driving the bidirectional threaded rod 43 to rotate in the first limit chute by the forward and reverse motor 42. Both threaded hole plates 44 are sleeved on the bidirectional threaded rod 43 through the threaded holes opened on their own bodies and are symmetrically arranged in the two first limit chutes. Two arc-shaped chucks 45 are symmetrically installed on the top walls of the two threaded hole plates 44, so that the arc surfaces of the two arc-shaped chucks 45 are arranged in the opposite direction. Thus, under the rotation action of the bidirectional threaded rod 43, the threaded hole plate 44 can drive the arc-shaped chuck 45 to move in the same or opposite direction, which is beneficial to adjusting according to the diameter of the gas turbine bearing. And when moving in the opposite direction, it can reversely clamp the gas turbine bearing sleeved on the arc-shaped chuck 45 to complete the limitation and prevent it from moving during the detection process and affecting the detection work.

[0023] Further, there is a temperature detection component 5 above the top wall of the workbench 1 for facilitating the heating and temperature detection of the gas turbine bearing. The temperature detection component 5 includes a first cylinder 51, a biaxial hinge 52, an opening activity rod 53, a first rotating shaft 54, an anti - detachment activity member 55, an electric heating arc panel 56, and a thermocouple temperature sensor 57. The output end of the first cylinder 51 is connected to the back wall of the biaxial hinge 52, which is beneficial for driving the biaxial hinge 52 to move. The two vertical shafts provided on the biaxial hinge 52 are respectively arranged in one opening of the two opening activity rods 53, so that the connection between the opening activity rod 53 and the biaxial hinge 52 can rotate; the two first rotating shafts 54 are respectively arranged in the other opening of the two opening activity rods 53, and the two first rotating shafts 54 are respectively installed in the notches opened on the two anti - detachment activity members 55, so that the first rotating shaft 54 cooperates with the other opening of the opening activity rod 53, and the connection between the anti - detachment activity member 55 and the opening activity rod 53 can rotate, enabling the biaxial hinge 52 to push the two anti - detachment activity members 55 to move in the same or opposite directions during the movement. The electric heating arc panel 56 and the thermocouple temperature sensor 57 are respectively installed at the bottom of the two anti - detachment activity members 55. Through the activity of the anti - detachment activity members 55, it is beneficial to adjust the distance between the electric heating arc panel 56 and the thermocouple temperature sensor 57 according to the diameter of the gas turbine bearing, improving the applicable range and providing convenience for subsequent detection and heating work.

[0024] Further, an adjustment component 6 for facilitating the movement of the temperature detection component 5 is arranged on the top wall of the support 2. The adjustment component 6 includes a second cylinder 61, a cross plate 62, a motor 63, a second rotating shaft 64 and a turntable 65. The two second cylinders 61 are symmetrically installed on the top wall of the support 2. The bottom wall of the cross plate 62 is fixedly connected to the output ends of the two second cylinders 61. The motor 63 is fixedly installed on the bottom wall of the cross plate 62. The top end of the second rotating shaft 64 passes through a third rotating hole opened on the top wall of the support 2 and is connected to the output end of the motor 63. The top wall of the turntable 65 is fixedly connected to the bottom end of the second rotating shaft 64, so that the motor 63 drives the second rotating shaft 64 to drive the turntable 65 to rotate, and under the drive of the second cylinder 61, the turntable 65 can be driven to lift through the cross plate 62, the motor 63 and the second rotating shaft 64; the first cylinder 51 is fixedly installed on the top wall of the turntable 65, so that the turntable 65 can drive the first cylinder 51 to lift during the lifting process, avoiding affecting the removal and replacement of the gas turbine bearing after the detection is completed; the side wall convex structures of the two anti-disengagement moving parts 55 are located in the second limit sliding grooves symmetrically opened on the wall of the turntable 65, which is beneficial to enabling the anti-disengagement moving parts 55 to move along the track of the second limit sliding groove, avoiding the deviation of their moving tracks and affecting the subsequent adjustment function. At the same time, under the rotation of the turntable 65, the temperature detection component 5 as a whole can rotate, so that the electrically heated arc panel 56 in the rotating state uniformly heats the gas turbine bearing, and in cooperation with the thermocouple temperature sensor 57 in the rotating state, multi-site temperature detection of the gas turbine bearing is realized, improving the accuracy of the detection result.
