The monitoring points of the existing detection device are single, which easily leads to inaccurate monitoring data. The monitoring points of the existing detection device need to be installed and debugged one by one with the rotary kiln and the supporting roller seat, and the overall installation is complicated. At the same time, the detection device is prone to resonance with the rotary kiln and the supporting roller seat, which affects the technical problem of monitoring data.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic detection device for the position of a rotary kiln roller comprises a rotary kiln, a roller seat and a detection mechanism, wherein roller seats are installed at both ends of the rotary kiln, and detection mechanisms for detecting vibration of the roller seats are installed at both ends of the rotary kiln, and the detection mechanism comprises a fixed ring cocentric with the rotary kiln, and a plurality of groups of slide rails are arranged at equal angles on the fixed ring, and a slider is slidably installed on the slide rail, and a support seat is installed on the slider, a vibration sensor is installed at the center of the inner side of the support seat, and the detection contact of the vibration sensor is in contact with the outer side of the roller seat, and sliders are installed at both ends of the inner side of the support seat and on both sides of the roller seat, and a movement sensor is installed on the inner side of the slider, and the detection contact of the movement sensor is in contact with the side wall of the roller seat.

[0007] Preferably, the detection mechanism further comprises a mounting plate connected to the ground embedded part, a plate seat is mounted on the mounting plate, a movable plate is mounted on the bottom side of the fixed ring, and the movable plate is mounted in the plate seat.

[0008] Preferably, both ends of the mounting plate are provided with a first mounting groove, and the plate seat is provided with a second mounting groove, wherein a screw rod passes through the second mounting groove and the movable plate, and both ends of the screw rod are connected to nuts.

[0009] Preferably, a first motor is installed at the end of the support seat, and sliding grooves are provided at both ends of the inner side of the support seat, and a threaded rod is installed in the sliding groove at the output end of the first motor.

[0010] Preferably, the threads at both ends of the threaded rod are in opposite directions, and both ends of the threaded rod are located in the slide groove and are threadedly connected to the detection block.

[0011] Preferably, a rotating ring is installed on the side wall of the fixed ring through a bearing, and external teeth are arranged on the outer side of the rotating ring. A fixing plate is arranged on the fixed ring, and a second motor is installed on the fixing plate.

[0012] Preferably, a plurality of guide grooves are formed at equal angles on the fixed ring, and the guide grooves are located between each set of slide rails, and a plurality of arc grooves are formed at equal angles on the rotating ring.

[0013] Preferably, a guide rod penetrating the guide groove and the arc groove is installed on the sliding block, a pneumatic cylinder is installed on the end of the guide rod, a clamping block is installed on the telescopic end of the pneumatic cylinder, and a ball is installed on the clamping block.

[0014] Preferably, the specific operating steps of the device are as follows:

[0015] Step 1: The detection mechanism is mounted on both ends of the rotary kiln, and the detection block is located on both sides of the supporting roller seat at this time. The mounting plate is pre-fixed with the ground embedded parts, and the plate seat and the movable plate are pre-fixed, that is, the bolts on the mounting plate and the nuts on the plate seat are all in a loose state, and the second motor on the fixed ring drives the rotating gear to rotate, and cooperates with the meshing external teeth to drive the rotating ring to rotate. At this time, the arc groove on the rotating ring acts on the guide rod, driving the guide rod to move along the guide groove, and the slider, support seat and pneumatic cylinder connected to the guide rod move synchronously. At the same time, the clamping block is driven to move through the expansion and contraction of the pneumatic cylinder, and the position of the clamping block is adjusted to ensure that the clamping block contacts the outer wall of the rotary kiln. At this time, the rotary kiln, the fixed ring and the rotating ring are co-centered, and then the ball on the clamping block is used to realize the horizontal movement of the fixed ring and the rotating ring to ensure that the supporting roller seat is located at the center of the support seat. After the fixed ring and the rotating ring are adjusted, the bolts on the mounting plate and the nuts on the plate seat are tightened to fix the fixed ring;

[0016] Step 2: The pneumatic cylinder contracts, the clamping block separates from the rotary kiln, and the rotating ring continues to rotate to drive the support seat to continue to approach the roller seat until the detection contacts of the vibration sensor are in contact with the outside of the roller seat. The first motor drives the threaded rod to rotate, and then drives the two threaded detection blocks to approach the roller seat until the detection contacts of the movement sensor on the detection block are in contact with the side wall of the roller seat. At this time, the contact point between the detection mechanism and the rotary kiln and the roller seat is the contact head of the sensor. When the rotary kiln rotates, the longitudinal vibration of the roller seat is monitored by the vibration sensor, and the lateral movement of the roller seat is monitored by the movement sensor.

[0017] The beneficial effects of the present invention are as follows: the rotating ring rotates, and the arc groove on the rotating ring acts on the guide rod, driving the guide rod to move along the guide groove, and the slider, the support seat and the pneumatic cylinder connected to the guide rod move synchronously, and at the same time, the clamping block is driven to move by the expansion and contraction of the pneumatic cylinder, and the position of the clamping block is adjusted to ensure that the clamping block contacts the outer wall of the rotary kiln. At this time, the rotary kiln, the fixed ring and the rotating ring are co-centered, the fixed ring is connected to the ground, and the overall translation of the detection mechanism is realized by the translation of the clamping block on the rotary kiln, so that the detection mechanism, the rotary kiln and the supporting wheel seat are accurately positioned and installed;

[0018] The pneumatic cylinder contracts, the clamp block separates from the rotary kiln, and the support seat continues to rotate through the rotating ring, driving it to continue to approach the roller seat, until the detection contacts of the vibration sensor are in contact with the outside of the roller seat, and the first motor drives the threaded rod to rotate, thereby driving the two threaded detection blocks to approach the roller seat, until the detection contacts of the movement sensor on the detection block are in contact with the side wall of the roller seat. At this time, the contact point between the detection mechanism and the rotary kiln and the roller seat is the contact head of the sensor. When the rotary kiln rotates, the longitudinal vibration of the roller seat is monitored by the vibration sensor, and the lateral movement of the roller seat is monitored by the movement sensor. At the same time, each sensor is subjected to the same contact force with the roller seat, ensuring that the measurement data of the vibration sensor and the movement sensor are close, and the roller seat is comprehensively monitored in terms of angle and multi-directions to ensure the accuracy of the monitoring data.

[0019] After installation, the detection mechanism is fixed on the ground, and only the detection heads of the vibration sensor and the movement sensor are in contact with the roller seat, so as to avoid the vibration of the rotary kiln and the roller seat causing resonance of the detection mechanism.
