Description

Technical Field

[0001] The present invention relates to the technical field of motor graders, and in particular to a device for reminding an angle positioner to replace a wear-resistant block, and a motor grader. Background Art

[0002] A motor grader is a type of construction machinery used for site leveling. It uses the cutting and leveling action of its blade to gradually smooth uneven ground. During operation, the motor grader can shovel, scrape, and fill soil as needed.

[0003] The motor grader's blade is mounted in the angle positioner. Wear blocks are installed at the contact area between the angle positioner and the blade. The blade transmits the applied force to the angle positioner via the wear blocks. During operation, the wear blocks gradually wear out due to wear and the impact of applied forces. When severely worn, the applied force during operation is directly transmitted to the angle positioner, potentially damaging it. Therefore, the wear blocks need to be replaced during use.

[0004] However, whether the wear-resistant block needs to be replaced requires manual observation of the wear degree of the wear-resistant block. The wear rate of the wear-resistant block is different in different working conditions. As a result, there is a situation where the user does not have a good grasp of the replacement cycle of the wear-resistant block, resulting in damage to the angle positioner, and the user experience is poor.

[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0037] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0038] An embodiment of the present invention provides a device for reminding users to replace the wear blocks of an angle positioner. This device is suitable for use in motor graders. It reminds users when the wear blocks of the angle positioner need to be replaced, helping to prevent damage to the angle positioner and improving the user experience. The angle positioner includes multiple U-shaped grooves, within which the wear blocks are positioned. Figure 1 This is a schematic diagram of a device for reminding an angle positioner to replace a wear-resistant block provided by an embodiment of the present invention. Figure 2 This is a side front view of the angle positioner provided by an embodiment of the present invention. Figure 1 and Figure 2 The angle positioner wear block replacement reminder device includes: a control module 120, a warning module 130 and at least one sensor module 110.

[0039] The sensor module 110 is arranged near the U-shaped groove 210; the sensor module 110 is used to detect the actual distance between the shovel and the first side plate of the U-shaped groove 210; wherein the first side plate is the side plate of the U-shaped groove 210 close to the sensor module 110; each sensor module 110 is connected to the control module 120; the control module 120 is used to generate a reminder signal when the actual distance is less than the preset distance; the warning module 130 is used to remind the user according to the reminder signal.

[0040] Specifically, the angle positioner's wear block is positioned within the U-shaped groove 210, and the wear block is also provided with a slot. The guide rail of the shovel blade is clamped within the slot of the wear block, and the guide rail of the shovel blade can slide within the slot of the wear block. During operation, the wear block is squeezed by the shovel blade, causing wear on the wear block, and the distance between the shovel blade and the first side plate of the U-shaped groove 210 will also change accordingly, that is, the shovel blade gradually approaches the first side plate of the U-shaped groove 210. In other words, the distance between the shovel blade and the first side plate of the U-shaped groove 210 is the thickness of the wear block.

[0041] The sensing module 110 detects the actual distance between the shovel and the first side plate of the U-shaped groove 210. The control module 120 obtains the actual distance between the shovel and the first side plate of the U-shaped groove 210 detected by the sensing module 110, and compares the actual distance with the preset distance. The control module 120 generates a reminder signal when the actual distance is less than the preset distance. The warning module 130 obtains the reminder signal and reminds the user according to the reminder signal. Exemplarily, the way in which the warning module 130 reminds the user may be an audible and visual alarm. It should be noted that the preset distance is the preset minimum distance between the shovel and the first side plate of the U-shaped groove 210, that is, the minimum thickness for replacement of the wear-resistant block. The preset distance depends on the working environment of the wear-resistant block and the material of the wear-resistant block itself. For example, the material of the wear-resistant block may be brass or nylon. In actual application, the preset distance can be set according to actual conditions, and this embodiment does not limit this.

[0042] In an embodiment of the present invention, the actual distance between the shovel blade and the first side plate of the U-shaped groove 210 is detected by the sensor module 110. The control module 120 obtains the actual distance detected by the sensor module 110 and generates a reminder signal when the actual distance is less than a preset distance. The warning module 130 obtains the reminder signal and reminds the user to replace the wear-resistant block according to the reminder signal. In an embodiment of the present invention, the actual distance between the shovel blade and the first side plate of the U-shaped groove 210 is detected by the sensor module 110 and reminds the user to replace the wear-resistant block when the actual distance is less than a preset distance, which helps to avoid damage to the angle positioner and improve user experience.

[0043] Figure 3 This is a schematic diagram of a grader working device provided by an embodiment of the present invention. Based on the above embodiment, optionally, Figure 2 and Figure 3 The sensing module 110 includes a sensor 111 and a bracket 112 .

[0044] The bracket 112 is disposed near the U-shaped groove 210 ; the sensor 111 is disposed on the bracket 112 ; the sensor 111 is used to detect the actual distance between the blade and the first side plate of the U-shaped groove 210 ; the bracket 112 is used to carry the sensor.

[0045] Specifically, the bracket 112 and the guide rail of the blade 310 are arranged on the same side. The bracket 112 is provided with an opening, and the sensor 111 is disposed within the opening of the bracket 112. The thickness of the wear-resistant block is equal to the horizontal distance between the blade and the first side plate of the U-shaped groove 210. Therefore, when the sensor 111 is fixed, the detection surface of the sensor 111 is perpendicular to the blade 310. This arrangement of the present embodiment helps improve the detection accuracy of the sensor 111. It should be noted that the type of sensor 111 can be selected according to actual circumstances, as long as it can detect the distance between the blade and the first side plate of the U-shaped groove 210. This embodiment does not impose any restrictions on this. For example, the sensor 111 can be a metal contact sensor. A metal contact sensor is a device that can detect the distance between a metal object and the metal contact sensor. When a metal object approaches the metal contact sensor, it causes a change in parameters such as resistance, capacitance, or inductance in the metal contact sensor, thereby generating a change in an electrical signal. The change in the electrical signal can be used to determine the distance between the metal object and the metal contact sensor.

[0046] Figure 4 This is a schematic diagram of another angle positioner wear block replacement reminder device provided by an embodiment of the present invention. Based on the above embodiments, optionally, refer to Figure 4 The angle positioner wear block replacement reminder device also includes: a communication positioning module 140.

[0047] The communication positioning module 140 is connected to the control module 120; the communication positioning module 140 is used to locate the position of the angle positioner wear block replacement reminder device and generate a positioning signal, and send a positioning signal and a reminder signal to the terminal.

[0048] Specifically, the communication positioning module 140 locates the position of the angle positioner wear block replacement reminder device, that is, locates the position of the grader equipped with the angle positioner wear block replacement reminder device. The communication positioning module 140 generates a positioning signal based on the positioning result and sends the positioning signal to the terminal. The terminal can be a mobile phone or a computer. The communication positioning module 140 also obtains the reminder signal. When the communication positioning module 140 obtains the reminder signal, the communication positioning module 140 sends the positioning signal and the reminder signal together to the terminal. The user can understand the position of each grader, the wear condition of the angle positioner wear block in each grader, and whether the angle positioner wear block needs to be replaced through the terminal. It should be noted that the communication method between the communication positioning module 140 and the terminal can be direct communication with the terminal or communication with the terminal through server relay. In actual application, it can be set according to actual needs, and this embodiment does not limit this. Optionally, the control module 120 and the communication positioning module 140 can be connected through a controller area network (CAN) bus. Specifically, the CAN bus is a serial communication network that effectively supports distributed control or real-time control.

[0049] Figure 5 This is a schematic diagram of another angle positioner wear block replacement reminder device provided by an embodiment of the present invention. Based on the above embodiments, optionally, refer to Figure 5 The communication and positioning module 140 includes: a communication unit 141 and a positioning unit 142 .

[0050] The communication unit 141 is connected to the control module 120; the communication unit 141 is also connected to the positioning unit 142; the positioning unit 142 is used to locate the position of the angle positioner wear block replacement reminder device and generate a positioning signal; the communication unit 141 is used to send a positioning signal and a reminder signal to the terminal.

[0051] Specifically, the positioning unit 142 locates the position of the angle positioner wear block replacement reminder device, that is, locates the position of the grader equipped with the angle positioner wear block replacement reminder device. The positioning unit 142 generates a positioning signal based on the positioning result. The communication unit 141 obtains the positioning signal and sends the positioning signal to the terminal. The terminal can be a mobile phone or a computer. The communication unit 141 also obtains the reminder signal. When the reminder signal is obtained, the communication unit 141 sends the positioning signal and the reminder signal to the terminal together. The user can understand the position of each grader, the wear condition of the angle positioner wear block in each grader, and whether the angle positioner wear block needs to be replaced through the terminal. It should be noted that the communication method between the communication unit 141 and the terminal can be direct communication with the terminal or communication with the terminal through server relay. In actual application, it can be set according to actual needs, and this embodiment does not limit this.

[0052] Based on the above embodiments, optionally, the number of sensor modules 110 is the same as the number of U-shaped slots 210. Specifically, under different working conditions, the degree of wear of each wear-resistant block in the angle positioner is not consistent. Therefore, it is necessary to detect the wear of the wear-resistant blocks in each U-shaped slot 210 to further prevent damage to the angle positioner.

[0053] Figure 6 This is a schematic diagram of another angle positioner wear block replacement reminder device provided by an embodiment of the present invention. Based on the above embodiments, optionally, refer to Figure 6 The warning module 130 includes: a display 131 .

[0054] The display 131 is connected to the control module 120 and is used to display a reminder sign in response to the reminder signal. Specifically, the reminder sign can be an icon, a prompt word, or a combination of an icon and a prompt word. In actual application, it can be set according to actual circumstances and this embodiment does not impose any restrictions on this.

[0055] Specifically, when used, the display 131 can be provided together with the control module 120 to improve the integration of the angle positioner wear block replacement reminder device and reduce the required area of ​​the angle positioner wear block replacement reminder device. In actual use, the angle positioner wear block replacement reminder device can be powered by the grader's battery, and the power supply of the control module 120 can be separated from the power supply of the display 131. In other words, turning off the display 131 does not affect the operation of the control module 120, thereby reducing the power consumption of the angle positioner wear block replacement reminder device. For example, the power supply of the display 131 can be controlled by the start switch of the grader.
