Description

Technical Field

[0001] The utility model relates to the technical field of piston oxygen compressors, in particular to a temperature measuring and controlling device for the piston rod of a piston oxygen compressor. Background Technique

[0002] As disclosed in the piston rod and sleeve clearance detection device of the integrated oxygen socket (application number: 202121860729.8) on the Chinese Patent Network, in order to ensure the normal operation of the piston rod, the distance between the piston rod and the sleeve is detected to prevent the piston rod from being too close or too far from the sleeve, resulting in the oxygen compressor being unable to be used normally. However, there is a lack of a detection mechanism for the surface temperature of the piston rod. If the temperature of the piston rod is too high, the oxygen compressor will also be unable to be used normally. Content of the Utility Model

[0003] Based on the technical problem that the existing piston rod detection mechanism cannot detect the surface temperature, the utility model proposes a temperature measuring and controlling device for the piston rod of a piston oxygen compressor.

[0004] A temperature measuring and controlling device for the piston rod of a piston oxygen compressor proposed by the utility model includes an oxygen compressor body and a base. Installation columns are fixedly installed on both side surfaces of the base. A control device is arranged inside the installation column. The control device includes a control motor, a driving bevel gear, a driven bevel gear, a threaded rod, and a pressing rod. When the control motor is started, the rotating shaft drives the driving bevel gear to rotate. The rotation of the driving bevel gear drives the driven bevel gear and the threaded rod to rotate. The rotation of the threaded rod controls the horizontal movement of the pressing rod.

[0005] Preferably, a sliding box is slidably inserted inside the installation column on the left side. The control motor is fixedly installed inside the sliding box. The driving bevel gear is fixedly installed on the rotating shaft of the control motor. A fixed box is fixedly installed on the oxygen compressor body.

[0006] Through the above technical solution, when the control motor is started, the rotating shaft drives the driving bevel gear to rotate, and the sliding box slides linearly inside the installation column.

[0007] Preferably, the pressing rod is slidably inserted inside the fixed box. Clamping rods are fixedly installed on both side surfaces of the sliding box. The outer surface of the clamping rod is slidably connected to the inside of the installation column. A rotating rod is rotatably connected inside the sliding box.

[0008] Through the above technical solution, the clamping rod slides inside the installation column, enabling the sliding box to move up and down linearly inside the installation column.

[0009] Preferably, a rotating circular plate is fixedly installed on the left end surface of the rotating rod. The outer surface of the rotating circular plate is rotatably connected to the inside of the sliding box. The threaded rod is threadedly connected to the inside of the extrusion rod. The driven bevel gear is fixedly installed on the left end of the threaded rod. The outer surface of the driven bevel gear is meshed with the outer surface of the driving bevel gear. The left side surface of the driven bevel gear is fixedly connected to the right end surface of the rotating rod.

[0010] Through the above technical solution, the rotating circular plate rotates within the sliding box, keeping the rotating rod stable in the sliding box. When the threaded rod rotates, it drives the extrusion rod to move horizontally.

[0011] Preferably, a telescopic motor is fixedly installed on the upper surface of the oxygen compressor body. A piston rod is slidably inserted into the inside of the fixed box. The right end surface of the piston rod is fixedly connected to the control mechanism of the telescopic motor. A moving circular rod is fixedly installed on the left end surface of the piston rod.

[0012] Through the above technical solution, when the telescopic motor is started, it controls the piston rod to move horizontally, driving the moving circular rod to move horizontally.

[0013] Preferably, a moving frame is fixedly installed on the left end surface of the moving circular rod. The lower surface of the moving frame is fixedly connected to the control mechanism of the oxygen compressor body. A lifting block is slidably inserted into the inside of the fixed box below the piston rod. The left inclined surface of the lifting block is slidably connected to the right inclined surface of the extrusion rod. A detection block is fixedly installed on the upper surface of the lifting block.

[0014] Through the above technical solution, the moving circular rod drives the moving frame to move horizontally, thereby controlling the operation of the oxygen compressor body. The extrusion rod squeezes the lifting block, causing the lifting block to move up and down.

[0015] Preferably, a thermometer is fixedly installed on the outer surface of the fixed box. The thermometer is electrically connected to the detection block through a wire. A buffer support mechanism is fixedly installed on the upper surface of the base. The upper end of the buffer support mechanism is fixedly connected to the lower surface of the oxygen compressor body. Clamping plates are fixedly installed on both side surfaces of the oxygen compressor body. Both of the clamping plates are slidably inserted into the inside of the installation column.

[0016] Through the above technical solution, the lifting block drives the detection block to contact the piston rod, and then the thermometer detects the temperature of the piston rod. The buffer support mechanism can reduce the vibration of the oxygen compressor body. The thermometer is connected to the DCS computer in the central control room through an optical fiber cable for configuration display and voice-controlled high-temperature alarm reminder.

[0017] The beneficial effects in the present utility model are:

[0018] By setting up a control device, when controlling the oxygen compressor body to work, the telescopic motor is started to control the piston rod to move horizontally, driving the moving round rod to move horizontally, and the moving round rod drives the moving frame to move horizontally, thereby controlling the operation of the oxygen compressor body. When detecting the temperature of the piston rod, the control motor is started, the rotating shaft drives the driving bevel gear to rotate, controls the driven bevel gear to rotate, so that the threaded rod rotates in the extrusion rod, controls the extrusion rod to extrude the lifting block, and enables the lifting block to drive the detection block to move upward. The detection block is closely attached to the surface of the piston rod for temperature measurement, and the thermometer can display the value. When the detected temperature exceeds a certain level, the computer in the background central control room will give an alarm to prevent the temperature of the piston rod from being too high, achieving the effect of facilitating the detection of the surface temperature of the piston rod.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Refer to Figures 1-4, A temperature measuring and controlling device for the piston rod of a piston oxygen compressor, comprising an oxygen compressor body 1 and a base 2. Mounting columns 3 are fixedly installed on both side surfaces of the base 2. To facilitate the detection of the surface temperature of the piston rod 13 inside the oxygen compressor, a control device is arranged inside the mounting column 3. The control device includes a control motor 4, a driving bevel gear 5, a driven bevel gear 6, a threaded rod 7, and an extrusion rod 8. When the control motor 4 is started, the rotating shaft drives the driving bevel gear 5 to rotate. The rotation of the driving bevel gear 5 drives the driven bevel gear 6 and the threaded rod 7 to rotate, and the rotation of the threaded rod 7 controls the horizontal movement of the extrusion rod 8.

[0026] To facilitate the control of the rotation of the driving bevel gear 5, a sliding box 31 is slidably inserted inside the left mounting column 3. The control motor 4 is fixedly installed inside the sliding box 31, and the driving bevel gear 5 is fixedly installed on the rotating shaft of the control motor 4. A fixed box 11 is fixedly installed on the oxygen compressor body 1. When the control motor 4 is started, the rotating shaft drives the driving bevel gear 5 to rotate, and the sliding box 31 slides linearly inside the mounting column 3.

[0027] To ensure that the sliding box 31 can move up and down linearly inside the mounting column 3, the extrusion rod 8 is slidably inserted inside the fixed box 11. Clamping rods 32 are fixedly installed on both side surfaces of the sliding box 31, and the outer surface of the clamping rod 32 is slidably connected to the inside of the mounting column 3. A rotating rod 33 is rotatably connected inside the sliding box 31. The clamping rod 32 clamps and slides inside the mounting column 3, enabling the sliding box 31 to move up and down linearly inside the mounting column 3.

[0028] To facilitate the control of the horizontal movement of the extrusion rod 8, a rotating circular plate 34 is fixedly installed on the left end surface of the rotating rod 33. The outer surface of the rotating circular plate 34 is rotatably connected to the inside of the sliding box 31. The threaded rod 7 is threadedly connected to the inside of the extrusion rod 8. The driven bevel gear 6 is fixedly installed on the left end of the threaded rod 7, and the outer surface of the driven bevel gear 6 meshes with the outer surface of the driving bevel gear 5. The left side surface of the driven bevel gear 6 is fixedly connected to the right end surface of the rotating rod 33. The rotating circular plate 34 clamps and rotates inside the sliding box 31, keeping the rotating rod 33 stable in rotation inside the sliding box 31. When the threaded rod 7 rotates, it drives the extrusion rod 8 to move horizontally.

[0029] To facilitate the control of the horizontal movement of the moving circular rod 14, a telescopic motor 12 is fixedly installed on the upper surface of the oxygen compressor body 1. A piston rod 13 is slidably inserted inside the fixed box 11. The right end surface of the piston rod 13 is fixedly connected to the control mechanism of the telescopic motor 12. A moving circular rod 14 is fixedly installed on the left end surface of the piston rod 13. When the telescopic motor 12 is started, it controls the horizontal movement of the piston rod 13, driving the moving circular rod 14 to move horizontally.

[0030] To facilitate the control of the extrusion block to extrude the lifting block 16, a moving frame 15 is fixedly installed on the left end surface of the moving round rod 14. The lower surface of the moving frame 15 is fixedly connected to the control mechanism of the oxygen compressor body 1. Inside the fixed box 11, a lifting block 16 is slidably inserted below the piston rod 13. The left inclined surface of the lifting block 16 is slidably connected to the right inclined surface of the extrusion rod 8. A detection block 17 is fixedly installed on the upper surface of the lifting block 16. The moving round rod 14 drives the moving frame 15 to move horizontally, thereby controlling the operation of the oxygen compressor body 1. The extrusion rod 8 extrudes the lifting block 16, causing the lifting block 16 to move up and down.

[0031] To facilitate high-temperature alarm reminder, a thermometer 18 is fixedly installed on the outer surface of the fixed box 11. The thermometer 18 is electrically connected to the detection block 17 through a wire. A buffer support mechanism 21 is fixedly installed on the upper surface of the base 2. The upper end of the buffer support mechanism 21 is fixedly connected to the lower surface of the oxygen compressor body 1. Clamping plates 19 are fixedly installed on both side surfaces of the oxygen compressor body 1. Both clamping plates 19 are slidably inserted into the inside of the mounting column 3. The lifting block 16 drives the detection block 17 to contact the piston rod 13, thereby enabling the thermometer 18 to detect the temperature of the piston rod 13. The buffer support mechanism 21 can reduce the vibration of the oxygen compressor body 1. The thermometer 18 is connected to the DCS computer in the central control room through an optical fiber cable for configuration display and voice-controlled high-temperature alarm reminder.

[0032] By setting up the control device, when controlling the oxygen compressor body 1 to operate, the telescopic motor 12 is started to control the piston rod 13 to move horizontally, driving the moving round rod 14 to move horizontally. The moving round rod 14 drives the moving frame 15 to move horizontally, thereby controlling the operation of the oxygen compressor body 1. When detecting the temperature of the piston rod 13, the control motor 4 is started to make the rotating shaft drive the driving bevel gear 5 to rotate, controlling the driven bevel gear 6 to rotate, so that the threaded rod 7 rotates inside the extrusion rod 8, controlling the extrusion rod 8 to extrude the lifting block 16, causing the lifting block 16 to drive the detection block 17 to move upward. The detection block 17 closely adheres to the surface of the piston rod 13 for temperature measurement. The thermometer 18 can display the value. When the detected temperature exceeds a certain level, the computer in the background central control room will give an alarm to prevent the temperature of the piston rod 13 from being too high, achieving the effect of facilitating the detection of the surface temperature of the piston rod 13.

[0033] Working principle: When controlling the oxygen compressor body 1 to work, start the telescopic motor 12 to control the horizontal movement of the piston rod 13, drive the moving round rod 14 to move horizontally, and the moving round rod 14 drives the moving frame 15 to move horizontally, thereby controlling the operation of the oxygen compressor body 1.
