Description

Technical Field

[0001] This invention relates to the field of interlocking safety protection devices, and in particular to a bearing device and its operation method with interlocking safety protection function. Background Technology

[0002] Mobile vertical shaft impact crushers are reliable and aesthetically pleasing. Equipped with a highly reliable vertical shaft impact crusher and hydraulic lubrication system, advanced electrical control, and optimized engine power matching, among other mature technologies, the overall design reaches international advanced levels. They are widely used for shaping and sand making of natural stones such as granite with medium to high hardness. However, due to the inherent structural characteristics of the main shaft assembly, the installation of the bearing end-face thermal resistors in mobile vertical shaft impact crushers is difficult. Furthermore, they are prone to poor contact with the main shaft or even falling off during operation. Once this occurs, the workload for replacing the end-face thermal resistors increases significantly, requiring the removal of the mobile vertical shaft impact crusher main unit. To avoid difficulties in installation, poor contact after installation, and easy detachment of the end-face thermal resistors, a reliable and efficient mechanism and operating method should be provided to reduce the occurrence of poor contact and detachment, thereby lowering the probability of failure. Therefore, how to reliably and quickly install the end-face thermal resistors, minimizing the workload of installation workers and improving installation quality, has become an urgent problem to be solved for mobile vertical shaft impact crushers.

[0008] Preferably, the adjustment assembly includes a lifting cylinder vertically disposed at the lower end of the resistance temperature detector. The lifting cylinder is placed inside the fastener, and a threaded line is provided on the outer side of the lifting cylinder. An internal threaded pipe is provided on the inner wall of the fastener, and the lifting cylinder is threadedly connected to the fastener. The top surface of the lifting cylinder abuts against the bottom surface of the movable seat, and a rotating block is fixedly connected to the outer side of the lower end of the lifting cylinder.

[0009] Preferably, a first connector is fixedly connected to the bottom surface of the probe. The first connector is placed inside the power base.

[0012] This invention also proposes an operating method for a bearing device with online interlock safety protection function, comprising the following steps:

[0013] S1. First, insert the RTD detector into the mounting hole on the outside of the bearing housing, so that the probe at the top of the RTD detector protrudes from inside the bearing housing. At this time, the plug at the bottom of the RTD detector is locked in the mounting hole. Then, connect the other end of the wire to the sensor and upload the data to the computer through the sensor. Next, install the roller bearing, ball bearing and shaft in sequence inside the bearing housing. Then connect the shaft to the drive device. The probe protruding inside the bearing housing is pushed back into the mounting hole by the installation of the roller bearing. At this time, the first spring is compressed and the upper end of the probe abuts against the outer surface of the roller bearing.

[0014] S2. After the resistance temperature detector is installed, connect the drive device to the wires and power it on. Then start the drive device and connect the output shaft of the drive device to the rotating shaft, thereby rotating the rotating shaft. At this time, the rotating shaft rotates in the roller bearing and ball bearing, thereby controlling the rotation of the rotor in the roller bearing and ball bearing, thereby generating heat. Then the resistance temperature detector detects the temperature of the roller bearing surface, and then the data is uploaded to the computer through the wires and sensors.

[0015] S3. When the drive unit runs for a long time, the roller bearing is always installed in the bearing housing. The first spring will experience elastic fatigue, which will cause the upper end of the probe to be unable to abut against the outer surface of the roller bearing. At this time, pinch the side wings on both sides of the fastener and rotate the lower end of the rotating block. The rotating block is fixed to the lower end of the lifting cylinder. The lifting cylinder is then threadedly connected to the fastener. When the rotating block rotates, the lifting cylinder rises inside the fastener, thereby pushing the moving seat upward and then pushing the lower connecting ring upward, so that the upper end of the probe abuts against the outer surface of the roller bearing. At this time, the length of the first spring is shortened and it is in a compressed state.

[0016] S4. When the temperature on the outer side of the roller bearing is too high, the surrounding air will diffuse into the mounting hole, causing the temperature around the wire at the upper end of the RTD detector to rise. The high temperature is isolated on the outside by the heat insulation sleeve, and then the metal heat dissipation wire is connected to the heat insulation sleeve. Thus, when the temperature is too high, the heat insulation sleeve and the metal heat dissipation wire ensure that the temperature of the wire at the upper end of the RTD detector is kept within a stable value, which facilitates better data uploading and improves the stability of data transmission. When the detection is completed, the drive device is powered off.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention facilitates rapid installation of the RTD detector through the cooperation of the plug and fasteners, preventing the device from easily falling off after installation; the cooperation of the first spring and the probe facilitates the probe to abut against the outside of the roller bearing, preventing poor contact or detachment between the RTD detector and the bearing end face; the cooperation of the lifting cylinder and the first spring facilitates the probe to abut against the outside of the roller bearing even if the first spring experiences elastic fatigue; the cooperation of the heat insulation sleeve and the metal heat dissipation wire facilitates the reduction of the temperature at the upper end of the wire, preventing excessive temperature from affecting data transmission; the cooperation of the first connector and the second connector facilitates rapid installation of the RTD detector and also facilitates rapid replacement of damaged components within the RTD detector, improving installation efficiency; this device reduces the probability of failure and improves installation efficiency.

[0019] 2. This invention, through the combination of plugs and fasteners, allows for convenient on-site installation, effectively shortening operation time, improving installation quality, and ensuring safe and reliable operation. It can be directly applied not only to mobile vertical shaft impact crushing plants but also to similar products such as stationary vertical shaft impact crushers. Attached Figure Description

[0035] Working principle: In this embodiment, the present invention also proposes a method for using a bearing device with online interlock safety protection function, including the following steps:

[0036] Step 1: First, insert the RTD detector 7 into the mounting hole 6 on the outside of the bearing housing 1, so that the probe 16 at the upper end of the RTD detector 7 protrudes from inside the bearing housing 1. At this time, the plug 8 at the lower end of the RTD detector 7 is locked in the mounting hole 6. Then, connect the other end of the wire 24 to the sensor, and upload the data to the computer through the sensor. Next, install the roller bearing 2, ball bearing 3 and shaft 4 in sequence inside the bearing housing 1. Then connect the shaft 4 to the drive device 5. The probe 16 protruding inside the bearing housing 1 is pushed back into the mounting hole 6 by the installation of the roller bearing 2. At this time, the first spring 12 is in a compressed state, and the upper end of the probe 16 abuts against the outer surface of the roller bearing 2.

[0037] Step 2: After the resistance temperature detector 7 is installed, connect the drive device 5 to the power supply and start the drive device 5. The output shaft of the drive device 5 is connected to the rotating shaft 4, which rotates the rotating shaft 4. At this time, the rotating shaft 4 rotates in the roller bearing 2 and the ball bearing 3, thereby controlling the rotation of the rotor in the roller bearing 2 and the ball bearing 3, thereby generating heat. The resistance temperature detector 7 then detects the temperature of the surface of the roller bearing 2, and the data is then uploaded to the computer through the wire 24 and the sensor.

[0038] Step 3: When the drive device 5 runs for a long time, the roller bearing 2 is always installed in the bearing housing 1. The first spring 12 will experience elastic fatigue, which will cause the upper end of the probe 16 to be unable to abut against the outer surface of the roller bearing 2. At this time, pinch the side wings on both sides of the fastener 9 and rotate the lower end of the rotating block 18. The rotating block 18 is fixed to the lower end of the lifting cylinder 17, and the lifting cylinder 17 is threadedly connected to the fastener 9. When the rotating block 18 rotates, the lifting cylinder 17 rises inside the fastener 9, thereby pushing the moving seat 10 upward, and then pushing the lower connecting ring 11 upward, so that the upper end of the probe 16 abuts against the outer surface of the roller bearing 2. At this time, the length of the first spring 12 is shortened and it is in a compressed state.

[0039] Step four: When the temperature on the outer side of the roller bearing 2 is too high, the surrounding air will diffuse into the mounting hole 6, thereby raising the temperature around the wire 24 at the upper end of the thermal resistance detector 7. The high temperature is isolated on the outside by the heat insulation sleeve 26, and then the metal heat dissipation wire 27 is attached to the heat insulation sleeve 26. Thus, when the temperature is too high, the heat insulation sleeve 26 and the metal heat dissipation wire 27 ensure that the temperature of the wire 24 at the upper end of the thermal resistance detector 7 is kept within a stable value, which facilitates better data uploading and improves the stability of data transmission. When the detection is completed, the drive device 5 is powered off.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The high temperature is isolated to the outside by the heat insulation sleeve (26), and then the metal heat dissipation wire (27) is attached to the heat insulation sleeve (26). Thus, when the temperature is too high, the heat insulation sleeve (26) and the metal heat dissipation wire (27) ensure that the temperature of the wire (24) at the upper end of the thermal resistance detector (7) is kept within a stable value, which facilitates better data transmission. When the detection is completed, the motor (5) is powered off.
