Description

Technical Field

[0001] The present invention mainly relates to the technical field of track wear monitoring, and in particular to a track wear monitoring device and a monitoring method thereof. Background Art

[0002] Tracks are widely used in engineering machinery and are part of crawler excavator walking devices. Since excavators generally work in relatively harsh environments, track wear monitoring is required.

[0003] According to a crawler excavator provided by the patent document with application number CN201810535550.1, the crawler excavator includes a lower walking track, a rotating platform arranged above the lower walking track, a cab and a counterweight mounted on the rotating platform, and a working device arranged in front of the rotating platform, wherein the working device includes a boom, a dipper arm and a bucket, and the lower walking track is composed of a driving wheel, a tensioning wheel, a walking wheel, a drag chain wheel, a tensioning device, a high-pressure jet device and a track frame, and a defect detection component is also provided for detecting whether the driving block of the track shoe is worn and deformed, so as to ensure the working performance of the excavator track.

[0004] The above-mentioned crawler excavator is provided with a defect detection component for detecting whether the drive block of the track shoe is worn or deformed, so as to ensure the working performance of the excavator track. The traditional track wear monitoring device uses a camera to photograph the track surface and then inputs the photos into a computer for comparison. This method is easily affected by impurities on the surface of the excavator track and affects the wear detection results. Summary of the invention

[0005] The present invention mainly provides a track wear monitoring device and a monitoring method thereof to solve the technical problems raised in the above background technology.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A track wear monitoring device comprises a monitoring box for the track to pass through, a cleaning mechanism is provided at one end of the monitoring box, and a defect monitoring mechanism is provided at the other end of the monitoring box;

[0008] The cleaning mechanism includes an exhaust pipe arranged on one side of the monitoring box, an air induction plate installed on a side surface of the exhaust pipe extending to the inside of the monitoring box, and a fender installed inside the monitoring box, and an air induction component is provided on the shell of the air induction plate;

[0009] The air induction assembly includes hinged seats installed at both ends of one side surface of the exhaust pipe, a wind shield rotatably connected to the inside of the hinged seat, and an accordion-type wind shield is connected between the wind shield and the air induction plate;

[0010] The defect monitoring mechanism comprises a reflector plugged into the top of the monitoring box and an industrial camera installed on the top of the reflector.

[0011] Furthermore, the air induced assembly also includes a gear coaxially arranged with the wind shield, one side of the gear is meshingly connected with a rack, the rack is connected to the execution end of the electric telescopic rod, and the electric telescopic rod is inserted into the top of the monitoring box. In the present invention, the wind shield coaxially arranged with the gear is driven to perform reciprocating angular displacement. Since the wind shield is located at the air outlet of the exhaust duct, the size of the air outlet of the exhaust duct is periodically adjusted through the periodic angular displacement of the wind shield, thereby changing the air outlet effect, so as to effectively deal with impurities on the track by utilizing the airflow discharged from different angles.

[0012] Furthermore, a plurality of reflective plates are installed inside the reflector, and the plurality of reflective plates are arranged around the industrial camera. In the present invention, the reflective plates reflect light, so that the industrial camera located near the reflective plates can take pictures conveniently.

[0013] Furthermore, the defect monitoring mechanism also includes a fill light installed at both ends of the monitoring box and located at the bottom of the reflector. In the present invention, the light emitted by the fill light provides lighting for the industrial camera near the fill light to facilitate the industrial camera to take pictures.

[0014] Furthermore, the cleaning mechanism also includes a blower installed on one side surface of the monitoring box, and the air outlet end of the blower is connected to the air inlet end of the exhaust duct through a pipe. In the present invention, the airflow discharged by the blower enters the exhaust duct through the pipe and is discharged through the exhaust duct. The airflow discharged by the exhaust duct blows away impurities on the surface of the crawler inserted into the monitoring box, thereby preventing the impurities attached to the crawler from affecting the photographing results of the industrial camera, thereby improving the accuracy of the photos taken by the industrial camera.

[0015] Furthermore, a contact switch is installed on one side surface of the exhaust duct, and the contact switch is electrically connected to the industrial camera. In the present invention, the contact switch is triggered by a windshield plate that performs reciprocating angular displacement. Since the contact switch is electrically connected to the industrial camera, the timing of turning on the industrial camera is controlled, so that the industrial camera cooperates with the windshield plate to clean the track and periodically photographs the cleaned track.

[0016] Furthermore, a slag discharge port is provided on the side of the monitoring box away from the exhaust pipe, and a landslide is provided at the bottom of the monitoring box. In the present invention, impurities falling to the bottom of the monitoring box are discharged through the landslide, thereby preventing impurities from accumulating in the monitoring box and causing secondary pollution to the track, thereby affecting the detection of track wear.

[0017] Furthermore, a support rod is installed at the top of the monitoring box near the end surface of the exhaust pipe, and a plurality of curtain pieces are arranged along a linear array on the lower surface of the support rod. In the present invention, the support rod is used to provide support for the plurality of curtain pieces, and the curtain pieces are used to block the opening of the monitoring box for the track to pass through, thereby reducing the dissipation of the airflow discharged from the exhaust pipe and facilitating the blowing away of impurities on the surface of the track.

[0018] According to the technical solution of the track wear monitoring device described above, a track wear monitoring method is also provided, comprising the following steps:

[0019] Step 1: Start the blower, the airflow discharged from the blower passes through the pipeline into the exhaust pipe and is discharged through the exhaust pipe, and the airflow discharged from the exhaust pipe blows away the impurities on the surface of the crawler inserted into the monitoring box;

[0020] Step 2, photographing the track shoe cleaned in step 1 by an industrial camera, and uploading the photograph to a computer connected to the industrial camera;

[0021] Step three, using a computer to compare the photos uploaded in step two to determine whether the track is worn.

[0022] Furthermore, in step one, when the airflow discharged from the exhaust pipe blows away the impurities on the surface of the crawler inserted into the monitoring box, the electric telescopic rod drives the rack connected to its execution end to rise and fall, thereby driving the wind shield plate coaxially arranged with the gear to perform reciprocating angular displacement, thereby changing the air outlet effect.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] Firstly, the present invention can quickly clean the track plate before detection, thereby reducing the influence of impurities attached to the track surface on the wear monitoring results. Specifically, the airflow discharged from the blower enters the exhaust pipe through the pipeline and is discharged through the exhaust pipe. The airflow discharged from the exhaust pipe blows away the impurities on the surface of the track inserted into the monitoring box.

[0025] Secondly, the electric telescopic rod of the present invention drives the rack connected to its execution end to rise and fall, and through the meshing of the rack and the gear, the gear converts the linear motion of the rack into its own rotational motion, thereby driving the wind shield plate coaxially arranged with the gear to perform reciprocating angular displacement. Since the wind shield plate is located at the air outlet of the exhaust duct, the size of the air outlet of the exhaust duct is periodically adjusted through the periodic angular displacement of the wind shield plate, thereby changing the air outlet effect, so as to effectively deal with impurities on the crawler track by utilizing the airflow discharged from different angles.
