Description

Technical Field

[0001] The utility model relates to the technical field of scraper wear detection for sweepers, in particular to a scraper wear degree detection device for sweepers. Background Art

[0002] A belt conveyor is a mechanical device that uses friction to continuously transport materials. It boasts high conveying capacity, long conveying distances, a simple structure, easy maintenance, and convenient programmable control and automated operation. During the conveying process, if residual material enters the roller or idler bearing seats, it can accelerate bearing wear. Material adhering to the roller or idler surfaces can tear and roughen the belt's surface, accelerating belt wear and damage. Therefore, a matching cleaner is essential.

[0003] The scraper in the sweeper is used to scrape off the attachments on the conveyor belt, but the scraper will continue to wear during use. This requires that fixed personnel be arranged to regularly inspect the sweeper to prevent secondary damage to the conveyor belt due to severe scraper wear. However, the current method of only relying on regular inspections by maintenance personnel to detect scraper wear is not only wasteful of manpower and material resources, but also the scraper wear may not be discovered in time and thus cannot be replaced in a timely and effective manner, and there is still a chance of causing secondary damage to the conveyor belt. Utility Model Content

[0004] In response to the above technical problems, the utility model provides a device for detecting the degree of scraper wear of a sweeper. By installing a monitoring component on the scraper, the degree of scraper wear can be monitored in real time. There is no need to arrange fixed personnel to inspect the sweeper regularly, which reduces manpower. A backup mechanism is also set up to avoid secondary damage to the conveyor belt due to the inability to scrape off attachments during the period of waiting for personnel to stop and replace the scraper.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A device for detecting the degree of wear of a scraper blade of a sweeper, characterized in that it includes a monitoring component and a backup mechanism, wherein the monitoring component is mounted on the scraper, the scraper is mounted on a scraper frame, the scraper frame is provided with a backup mechanism, the monitoring component is composed of a machine box, a circuit board, a wear sensor and a wear part, the machine box is fixedly mounted on the inner side of the scraper with screws, a circuit board is provided in the machine box, a wear sensor is mounted on the circuit board, the wear sensor is connected to the wear part, and the upper edge of the wear part is flush with the tip of the scraper.

[0007] The backup mechanism consists of a positioning cylinder, a limiting stud, a mounting seat, an electric telescopic rod and a backup scraper. The positioning cylinder is sleeved on the fixed shaft of the scraper frame. The threaded hole provided on the positioning cylinder is threadedly connected to the limiting stud. The mounting seat is fixed on the positioning cylinder. The electric telescopic rod is installed in the mounting seat. The telescopic end of the electric telescopic rod is connected to the backup scraper.

[0008] The spare scraper is located in a groove provided on the mounting seat.

[0009] Specifically, the monitoring component and the electric telescopic rod are electrically connected to the main controller on the circuit board in the control panel through wires. The control panel is equipped with a buzzer and a display screen, and the main controller is electrically connected to the buzzer and the display screen respectively.

[0010] Specifically, the main controller adopts a PLC controller.

[0011] Beneficial effects of the utility model:

[0012] The utility model installs a monitoring component on the scraper. During the cleaning process, the wear part of the monitoring component wears away together with the scraper. The wear sensor can sense the wear change of the wear part in real time and convert the wear signal into an electrical signal output. The signal is processed and analyzed by the PLC controller and transmitted to the display screen to display the wear degree of the scraper. There is no need to arrange fixed personnel to regularly inspect the cleaner, which reduces manpower.

[0013] When the degree of wear reaches the preset value, the PLC controller controls the buzzer to start to remind the staff, and turns on the electric telescopic rod in the standby mechanism, controlling the spare scraper to extend from the groove and contact the conveyor belt to scrape off the attachments on the conveyor belt, which greatly avoids the situation where the conveyor belt is damaged again due to the inability to scrape off the attachments while waiting for the staff to stop the machine to replace the scraper.

[0022] Example 1

[0023] As shown in the figure, the monitoring component consists of a machine box 11, a circuit board, a wear sensor and a wear part 12. The machine box 11 is fixedly installed on the inner side of the scraper 2 with screws. A circuit board is set in the machine box 11, and the circuit board is equipped with a wear sensor. The wear sensor is connected to the wear part 12. The upper edge of the wear part 12 is flush with the tip of the scraper 2. It should be noted that the wear sensor is an existing sensor that can be purchased. Its monitoring principle is to use the induction principle to monitor the wear of the wear part. When the wear part gradually wears during use, the sensor can sense this change in real time.

[0024] The scraper 2 is installed on the scraper frame 3, and a spare mechanism is provided on the scraper frame 3. The spare mechanism consists of a positioning cylinder 41, a limiting stud 44, a mounting seat 42, an electric telescopic rod 45 and a spare scraper 43. The positioning cylinder 41 is sleeved on the fixed shaft of the scraper frame 3, and the threaded hole provided on the positioning cylinder 41 is threadedly connected to the limiting stud 44, which is installed on the scraper frame 3 by tightening the limiting stud. The mounting seat 42 is fixed on the positioning cylinder 41, and the electric telescopic rod 45 is installed in the mounting seat 42. The telescopic end of the electric telescopic rod 45 is connected to the spare scraper 43, and the spare scraper 42 is located in the groove provided on the mounting seat 42.

[0025] The monitoring component and the electric telescopic rod 45 are electrically connected to the main controller on the circuit board in the control panel 51 through wires. A buzzer 53 and a display screen 52 are installed on the control panel 51. The main controller on the circuit board is electrically connected to the buzzer 53 and the display screen 52 respectively. It should be noted that the control panel 51 can be installed in a position that is convenient for staff to observe according to the situation, and then the control panel is connected to the monitoring component and the electric telescopic rod 45 through cables. Among them, the main controller can be a PLC controller.

[0026] Example 2

[0027] The cleaner is installed on the belt conveyor so that the scraper 2 is in contact with the conveyor belt, and the spare scraper 43 is adjusted so that it is also in contact with the conveyor belt. After the adjustment operation, the electric telescopic rod 45 is started to control the scraper 43 to move into the groove of the mounting seat so that the tip of the spare scraper 43 does not contact the conveyor belt.

[0028] During the cleaning process, the wear part 12 in the monitoring assembly wears together with the scraper 2. The wear sensor can sense the wear changes of the wear part in real time and convert the wear signal into an electrical signal output. The signal is processed and analyzed by the PLC controller and transmitted to the display screen to display the degree of scraper wear. This eliminates the need to arrange fixed personnel to regularly inspect the sweeper, reducing manpower.

[0029] When the degree of wear reaches a preset value, the PLC controller controls the buzzer 53 to start making a sound to remind the staff to perform maintenance and replacement, and the PLC controller sends a control command to control the electric telescopic rod in the standby mechanism to extend, and controls the standby scraper 43 to extend from the groove and abut against the conveyor belt. The standby scraper 43 is used to scrape off the attachments on the conveyor belt, which greatly avoids the situation where the conveyor belt is damaged again due to the inability to scrape off the attachments during the period of waiting for the staff to stop the machine to replace the scraper.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. The various components mentioned in the present invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
