Description

Technical Field

[0001] This utility model relates to the field of road construction equipment, and in particular to a road construction stabilization grinding device. Background Technology

[0002] Road engineering encompasses the comprehensive planning, design, construction, maintenance, and management of roads, as well as the physical engineering entities involved in these activities. Like other branches of civil engineering, road engineering also possesses significant technical, economic, and managerial attributes.

[0003] Road surface smoothness is a key indicator for measuring the quality and service level of road construction. It involves measuring the unevenness of the road surface intermittently or continuously using a specified standard range; in other words, it's a quantitative indicator of road surface roughness. Since the road surface layer is in direct contact with vehicles, any unevenness increases driving resistance and causes additional vibrations. This vibration not only causes bumps but also affects driving speed, safety, and the smoothness and comfort of driving. Especially in situations with extremely high requirements, such as airports or highways, smoothness becomes a crucial factor in controlling road surface quality.

[0004] In some construction sites, especially in areas with high requirements for road surface smoothness, such as airports and highways, it is necessary to finely grind protruding parts. Currently, the commonly used method is to complete the grinding process manually or semi-manually, which is not only inefficient but also makes it difficult to ensure the efficient execution of the grinding process and the final smoothness. Utility Model Content

[0005] The main purpose of this utility model is to provide a stable grinding equipment for road construction, which aims to solve the problems of low efficiency and difficulty in ensuring efficient grinding and final flatness in the commonly used manual or semi-manual methods of road construction grinding equipment.

[0006] To achieve the above objectives, this utility model provides a road construction stabilization grinding device, comprising:

[0007] The transfer vehicle includes a vehicle body, on which a hydraulic workstation is installed. A hydraulic support leg is installed at each of the four corners of the vehicle body. The hydraulic support legs are connected to the hydraulic workstation, and the operation of the four hydraulic support legs is independently controlled.

[0008] A telescopic arm is installed on the vehicle body, and its extension and retraction direction is consistent with the width direction of the vehicle body.

[0009] The base is installed at the free end of the telescopic arm;

[0010] A first hydraulic drive is disposed on the base and operates in the vertical direction and is connected to the hydraulic workstation;

[0011] A grinding assembly includes a motor mounting base and a motor mounted on the motor mounting base. The motor mounting base is connected to the output end of the first hydraulic drive. The motor is located at the middle of the base along its length. The motor output end is located below and connected to a grinding disc.

[0012] A laser-type road surface evenness gauge is connected to one end of the base along its length and extends along the width of the vehicle body.

[0013] Furthermore, the base is equipped with a downward-facing distance sensor.

[0014] Furthermore, a control center is provided on the vehicle body, and the sensing data of the distance sensor is transmitted to the control center.

[0015] Furthermore, the sensor data of the laser-type road surface evenness meter is transmitted to the control center.

[0016] Furthermore, when the telescopic arm is in the retracted state, the laser-type road surface smoothness gauge is located below the vehicle body.

[0017] Furthermore, the vehicle body is provided with a hanging component, and the end of the laser road surface evenness gauge away from the base slides and cooperates with the hanging component.

[0018] Furthermore, the first hydraulic drive is disposed on the upper surface of the base.

[0019] Furthermore, the motor mounting base includes two vertical guide rods that slide in cooperation with the base. The upper and lower ends of the two guide rods are respectively connected to an upper plate and a lower plate, and the free end of the first hydraulic drive supports the upper plate.

[0020] Furthermore, the vehicle body is also equipped with a second hydraulic drive connected to the hydraulic workstation, which drives the telescopic arm to reciprocate along the length of the vehicle body.

[0021] Furthermore, a level indicator is provided on the vehicle body.

[0022] The road construction stabilization grinding equipment provided by this utility model includes a laser-type road surface evenness gauge connected to the base and extending along the width of the vehicle body. As the transfer vehicle moves along the length of the road, the laser-type road surface evenness gauge moves accordingly, allowing for a wide-range scan. When the laser-type gauge detects unevenness, the grinding component is moved to the relevant location on the road by the movement of the transfer vehicle along the road length and the extension and retraction of the telescopic arm along the road length. When the grinding component reaches the working position, it is stably supported by hydraulic support legs, and the independent length adjustment of each hydraulic support leg completes the leveling process. Finally, the grinding disc of the grinding component contacts the road surface through the operation of the first hydraulic drive, completing the grinding process. This achieves efficient and high-quality completion of the grinding process. Attached Figure Description

[0030] Reference Figures 1 to 3 In one embodiment of this utility model, a road construction stabilization grinding device includes:

[0031] The transfer vehicle 100 includes a vehicle body 110, on which a hydraulic work station 120 is provided. A hydraulic support leg 130 is provided at each of the four corners of the vehicle body 110. The hydraulic support legs 130 are connected to the hydraulic work station 120. The operation of the four hydraulic support legs 130 is independently controlled.

[0032] The telescopic arm 200 is installed on the vehicle body 110, and its extension and retraction direction is consistent with the width direction of the vehicle body 110.

[0033] The base 300 is installed at the free end of the telescopic arm 200;

[0034] A first hydraulic drive 400 is disposed on the base 300 and operates in the vertical direction and is connected to the hydraulic workstation 120;

[0035] The grinding assembly 500 includes a motor mounting base 530 and a motor 510 mounted on the motor mounting base 530. The motor mounting base 530 is connected to the output end of the first hydraulic drive 400. The motor 510 is located at the middle of the base 300 in the length direction. The output end of the motor 510 is located below and connected to a grinding disc 520.

[0036] A laser-type road surface evenness gauge 600 is connected to one end of the base 300 along its length and extends along the width of the vehicle body 110.

[0037] In the current technology, road grinding is usually carried out manually or semi-manually. This method is not only inefficient, but also makes it difficult to ensure that the grinding process is efficient and that the final smoothness is achieved.

[0038] In this invention, the road construction stabilization and grinding equipment includes a transfer vehicle 100, which comprises a main body 110. Multiple transfer wheels are mounted on the lower part of the main body 110, enabling the transfer vehicle 100 to move. A hydraulic workstation 120 is mounted on the main body 110. A hydraulic support leg 130 is located at each of the four corners of the main body 110 and is connected to the hydraulic workstation 120. When the road construction stabilization and grinding equipment reaches its working position, the hydraulic support legs 130 provide stable support, and the independent length adjustment of each hydraulic support leg 130 allows for horizontal adjustment. The direction of movement of the transfer vehicle 100 is its length direction. The general operating mode of the transfer vehicle 100 is to move along the length of the road.

[0039] The telescopic boom 200 is mounted on the vehicle body 110. The telescopic boom 200 extends in the same direction as the width of the vehicle body 110. The base 300 is mounted on the free end of the telescopic boom 200.

[0040] The first hydraulic drive 400 is disposed on the base 300 and operates in the vertical direction and is connected to the hydraulic workstation 120. The first hydraulic drive 400 can be disposed at the upper end or the lower end of the base 300.

[0041] The grinding assembly 500 includes a motor mounting base 530 and a motor 510 mounted on the motor mounting base 530. The motor mounting base 530 is connected to the output end of the first hydraulic drive 400. The motor 510 is positioned at the middle of the base 300 along its length, and its output end is located below and connected to a grinding disc 520. The working height of the grinding assembly 500 is adjusted by the operation of the first hydraulic drive 400.

[0042] A laser-type road surface smoothness gauge 600 is connected to one end of the base 300 along its length and extends along the width of the vehicle body 110. Therefore, the extension direction of the laser-type road surface smoothness gauge 600 is the width direction of the road. As the transfer vehicle 100 moves along the length of the road, the laser-type road surface smoothness gauge 600 moves accordingly, allowing it to perform a wide-area scan. When the laser-type road surface smoothness gauge 600 detects unevenness at a relevant road location, the movement of the transfer vehicle 100 along the road length and the extension and retraction of the telescopic arm 200 along the road length move the grinding component 500 to the relevant road location. Finally, the operation of the first hydraulic drive 400 brings the grinding disc 520 of the grinding component 500 into contact with the road surface, completing the grinding process.

[0043] In summary, the laser-type road surface smoothness gauge 600 is connected to the base 300 and extends along the width direction of the vehicle body 110. As the transfer vehicle 100 moves along the length of the road, the laser-type road surface smoothness gauge 600 moves accordingly, allowing it to perform a wide-range scan. When the laser-type road surface smoothness gauge 600 detects unevenness, the movement of the transfer vehicle 100 along the road length and the extension / retraction of the telescopic arm 200 along the road length move the grinding component 500 to the relevant position on the road. When the grinding component 500 reaches the working position, it is stably supported by the hydraulic support legs 130, and the independent length adjustment of each hydraulic support leg 130 completes the horizontal adjustment process. Finally, the operation of the first hydraulic drive 400 causes the grinding disc 520 of the grinding component 500 to contact the road surface, completing the grinding process. This achieves efficient and high-quality completion of the grinding process.

[0044] In one embodiment, the base 300 is provided with a downward-facing distance sensor.

[0045] In this embodiment, the distance sensor can be ultrasonic, and it guides the driving dimensions of the first hydraulic drive 400 during operation. For example, the detection result of the laser road surface smoothness gauge 600 shows a certain degree of unevenness in the road surface, while the position of the laser road surface smoothness gauge 600 has deviated from the position of the uneven road surface during the operation of the grinding component 500. At this time, the signal from the distance sensor provides working guidance for the first hydraulic drive 400.

[0046] Reference Figures 1 to 2 In one embodiment, a control center 140 is provided on the vehicle body 110, and the sensing data of the distance sensor is transmitted to the control center 140.

[0047] In this embodiment, the test data from the distance sensor is transmitted to the control center 140, allowing operators on the transfer vehicle 100 to access the relevant test data. The control center 140 may include a processing module, a display module, and an input module, among others.

[0048] In one embodiment, the sensor data of the laser-type road surface evenness meter 600 is transmitted to the control center 140.

[0049] In this embodiment, the relevant test data of the laser road surface evenness tester 600 is transmitted to the control center 140, so that the operator on the transfer vehicle 100 can obtain the relevant test data through the control center 140.

[0050] Reference Figure 2In one embodiment, when the telescopic arm 200 is in a retracted state, the laser-type road surface smoothness gauge 600 is located below the vehicle body 110.

[0051] In this embodiment, considering that the laser road surface smoothness gauge 600 moves along with the telescopic arm 200, the shape of the vehicle body 110 and the position of the laser road surface smoothness gauge 600 are defined so that when the telescopic arm 200 is in the retracted state, the laser road surface smoothness gauge 600 is located below the vehicle body 110, so that the entire telescopic arm 200 does not need to consider the interference of the laser road surface smoothness gauge 600 during operation.

[0052] In one embodiment, a hanging device is provided on the vehicle body 110, and the end of the laser road surface evenness meter 600 away from the base 300 slides and cooperates with the hanging device.

[0053] In this embodiment, the suspension bracket makes the laser-type road surface evenness gauge 600 more stable. Since the laser-type road surface evenness gauge 600 moves along with the telescopic arm 200, the laser-type road surface evenness gauge 600 and the suspension bracket need to be slidably positioned. For example, the laser-type road surface evenness gauge 600 has a slot, and the suspension bracket has a protruding structure corresponding to the slot, thus allowing for a sliding fit between the two.

[0054] Reference Figures 1 to 3 In one embodiment, the first hydraulic drive 400 is disposed on the upper surface of the base 300.

[0055] In this embodiment, since the motor 510 is preferably positioned below the base 300, the first hydraulic drive 400 is positioned on the upper surface of the base 300 to provide space for the installation of the motor 510.

[0056] Reference Figures 1 to 3 In one embodiment, the motor mounting base 530 includes two vertical guide rods 531 that slide in cooperation with the base 300. The upper and lower ends of the two guide rods 531 are respectively connected to an upper plate 532 and a lower plate 533, and the free end of the first hydraulic drive 400 supports the upper plate 532.

[0057] In this embodiment, the upper plate 532 serves as the base for the first hydraulic drive 400, the motor 510 is mounted on the lower plate 533, and the cooperation between the guide rod 531 and the base 300 ensures accurate positioning of the motor mounting base 530 during sliding. A linear bearing can also be provided on the base 300 corresponding to the guide rod 531, further smoothing the sliding process of the guide rod 531.

[0058] Reference Figures 1 to 2In one embodiment, the vehicle body 110 is further provided with a second hydraulic drive 150 connected to the hydraulic workstation 120, and the second hydraulic drive 150 drives the telescopic arm 200 to reciprocate in the length direction of the vehicle body 110.

[0059] In this embodiment, after the laser-type road surface evenness tester 600 detects unevenness in the road surface, the grinding assembly 500 is driven to a suitable position by the operation of the second hydraulic drive 150 and the telescopic arm 200. Since the position of the laser-type road surface evenness tester 600 has deviated from the location of the uneven road surface during the operation of the grinding assembly 500, after the grinding assembly 500 completes its work, the second hydraulic drive 150 re-drives the laser-type road surface evenness tester 600 back to the road surface position, completing the evenness inspection.

[0060] In one embodiment, a level indicator is provided on the vehicle body 110.

[0061] In this embodiment, the adjustment process of the four hydraulic support legs 130 can be guided by the leveling indicator. The specific form and model of the leveling indicator are not the focus. Since the leveling indicator is installed on the vehicle body 110, there is no need to provide related devices during use.

[0062] In summary, the road construction stabilization grinding equipment provided by this utility model includes a laser-type road surface smoothness gauge 600 connected to the base 300 and extending along the width direction of the vehicle body 110. As the transfer vehicle 100 moves along the length of the road, the laser-type road surface smoothness gauge 600 moves accordingly, allowing it to perform a wide-range scan. When the laser-type road surface smoothness gauge 600 detects unevenness, the grinding component 500 is moved to the relevant position on the road by the movement of the transfer vehicle 100 along the road length and the extension and retraction of the telescopic arm 200 along the road length. When the grinding component 500 reaches the working position, it is stably supported by hydraulic support legs 130, and the independent length adjustment of each hydraulic support leg 130 completes the horizontal adjustment process. Finally, the grinding disc 520 of the grinding component 500 contacts the road surface through the operation of the first hydraulic drive 400, completing the grinding process. This achieves efficient and high-quality completion of the grinding process.
