Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, specifically to a paver. Background Technology

[0002] A paver is a type of construction machinery used for laying various road surface materials. Currently, pavers consist of a material placement device and a screed device. After the material placement device lays the material, the screed device presses it down to improve smoothness and strength. In related technologies, the screed device uses a telescopic structure. When the screed device extends, some material accumulates in the area between the material placement device and the extended part of the screed device. Because this portion of material lacks the direct action of the material placement device, it accumulates to a relatively high height, resulting in poor subsequent pressing effects. Utility Model Content

[0003] To address the aforementioned technical problems, embodiments of this application provide a paver that can improve the problem of excessive material accumulation height between the end of the fabric spreading device and the end of the telescopic part, thereby enhancing the smoothing effect of the material between the end of the fabric spreading device and the end of the telescopic part.

[0007] An ironing device includes a main body and a telescopic part. The main body is connected to the machine body, and the telescopic part is slidably connected to the main body along the length direction of the main body. At least a portion of the telescopic part can extend out of the main body.

[0008] An auxiliary conveying device is connected to the machine body, and at least a portion of the auxiliary conveying device is disposed between the end of the fabric device and the end of the telescopic part. The auxiliary conveying device is used to disperse the material between the end of the fabric device and the end of the telescopic part.

[0015] A drive unit is disposed on the housing and is connected to the screw conveyor.

[0016] According to a first aspect of this application, the housing is provided with an opening, and the housing is disposed in a portion of the spiral conveyor through the opening.

[0017] According to a first aspect of this application, the transport body further includes:

[0021] The second arm is rotatably connected to the end of the first arm away from the machine body, and the end of the second arm away from the first arm is rotatably connected to the conveying body.

[0022] According to a first aspect of this application, the telescopic portion includes:

[0023] An ironing body is slidably connected to the main body along its length.

[0024] A first baffle is distributed at intervals from the main body along the length direction of the main body, and the first baffle is connected to the end of the ironing body away from the main body;

[0025] The second baffle is connected to the first baffle, and the second baffle is spaced apart from the ironing body. The main body is located between the second baffle and the ironing body.

[0026] The auxiliary conveying device is at least partially disposed between the first baffle, the second baffle, and the fabric feeding device.

[0027] According to a first aspect of this application, a notch is formed between the auxiliary conveying device and the end of the first baffle away from the ironing body, and the auxiliary conveying device is used to disperse material between the ends of the first baffle, the second baffle and the fabric device through the notch to a region on the side of the first baffle away from the second baffle.

[0028] According to a first aspect of this application, the paver further includes:

In other words, the auxiliary conveying device can disperse excessively high material between the ends of the fabric spreading device and the telescopic section, resulting in a more uniform material height distribution. This improves the pressing effect of the subsequent telescopic section on the material between the ends of the fabric spreading device and the telescopic section, while also mitigating the problems of uneven stress and easy deformation of the telescopic section during pressing.

Detailed Implementation

[0039] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0040] Figure 1 This is a schematic diagram of the structure of a paver provided for an exemplary embodiment of this application. Figure 1 As shown, the paver 100 provided in this application embodiment may include a body 110, a fabric spreading device 120 and an ironing device 130, both of which are connected to the body 110.

[0041] In practical applications, the spreading device 120 and the ironing device 130 work together to improve the quality of road paving. Specifically, the spreading device 120 can evenly spread the material in the hopper (set on the machine body 110) onto the road surface, while the ironing device 130 can iron and press the spread material to improve the flatness of the material after paving.

[0042] In practical applications, in order to adapt to road surfaces of different widths, the ironing device 130 will adopt a telescopic structure to enable it to complete the ironing operation on road surfaces of different widths.

[0043] Specifically, such as Figure 1 As shown, the ironing device 130 may include a main body 131 and a telescopic part 132. The main body 131 is connected to the machine body 110, and the telescopic part 132 extends along the length of the main body 131 (see reference for details). Figure 1 The main body 131 is slidably connected in the Y-axis direction.

[0044] It should be understood that after the telescopic part 132 extends out of the main body 131 along its length, the overall length of the ironing device 130 increases, making it applicable to wider roads. In practical applications, only a portion of the telescopic part 132 may extend out of the main body 131; or, the entire telescopic part 132 may extend out of the main body 131 (reaching its maximum length).

[0045] like Figure 1 As shown, in actual construction, at least a portion of the telescopic part 132 extends out of the main body 131, and a stacking area 140 can be formed between the end of the telescopic part 132 and the end of the fabric spreading device 120. During the fabric spreading process of the fabric spreading device 120, some of the material will move outside the coverage area of ​​the fabric spreading device 120 under the action of compression, that is, some of the material will move into the stacking area 140. The stacking area 140 can receive some of the material output by the fabric spreading device 120, and the telescopic part 132 can iron the material in the stacking area 140.

[0046] It should be noted that in the relevant technology, since the material in the stacking area 140 lacks the direct action of the spreading device 120, the material in the stacking area 140 may have excessively high stacking height and uneven dispersion. This will result in poor ironing effect of the telescopic part 132 on the material in the stacking area 140. Furthermore, excessively high stacking of material will also cause uneven force on the telescopic part 132 during ironing, making it prone to deformation.

[0047] Therefore, such as Figure 1 As shown, the paver 100 provided in this application embodiment may further include an auxiliary conveying device 150, which is connected to the machine body 110. At least a portion of the auxiliary conveying device 150 is disposed between the end of the spreading device 120 and the end of the telescopic part 132 (within the material stockpiling area 140 in actual construction). The auxiliary conveying device 150 can be used to disperse the material between the end of the spreading device 120 and the end of the telescopic part 132 (within the material stockpiling area 140 in actual construction). In other words, the auxiliary conveying device 150 can disperse the excessively tall material between the end of the fabric device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction), making the height distribution of the material between the end of the fabric device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction) more uniform. This is beneficial to improving the ironing effect of the telescopic part 132 on the material between the end of the fabric device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction), and at the same time, it improves the problem of uneven force and easy deformation of the telescopic part 132 during the ironing process.

[0048] In one embodiment, such as Figure 1As shown, the fabric feeding device 120 can be a screw conveyor. The length direction of the main body 131 is parallel to the axial direction of the screw conveyor. When at least part of the telescopic part 132 extends out of the main body 131, the aforementioned stacking area 140 can be formed between the end of the screw conveyor and the end of the telescopic part 132. Some material will be squeezed from the end of the screw conveyor into the stacking area 140.

[0049] In one embodiment, a portion of the auxiliary conveying device 150 may extend between the end of the fabric spreading device 120 and the end of the telescopic part 132 (within the material stacking area 140 during actual construction).

[0050] In one embodiment, the entire auxiliary conveying device 150 may extend between the end of the fabric spreading device 120 and the end of the telescopic part 132 (within the material stacking area 140 during actual construction).

[0051] like Figure 1 As shown, the telescopic part 132 may include an ironing body 1321, a first baffle 1322 and a second baffle 1323. The ironing body 1321 is slidably connected to the main body 131 along the length direction of the main body 131. The first baffle 1322 is spaced apart from the main body 131 along the length direction of the main body 131. The first baffle 1322 is connected to the end of the ironing body 1321 away from the main body 131. The second baffle 1323 is connected to the first baffle 1322. The second baffle 1323 is spaced apart from the ironing body 1321. The main body 131 is located between the second baffle 1323 and the ironing body 1321.

[0052] It should be noted that at least a portion of the aforementioned auxiliary conveying device 150 is located between the ends of the first baffle 1322, the second baffle 1323, and the fabric spreading device 120. In actual construction, a material stacking area 140 can be formed between the first baffle 1322, the second baffle 1323, and the fabric spreading device 120. Specifically, the first baffle 1322 can restrict the material in the stacking area 140 to prevent material leakage; the second baffle 1323 can push and scrape the material in the stacking area 140, providing a relatively flat material for the telescopic section 132, which is beneficial to improving the ironing effect of the subsequent telescopic section 132.

[0053] In practical applications, there is a need for ultra-wide paving operations. Specifically, when the telescopic section 132 extends to its maximum length beyond the main body 131, the distance between the first baffle 1322 and the main body 131 is at its maximum, and the material storage area 140 is at its maximum. Even in this state, the road width requirement cannot be met, necessitating the transfer of some material from the material storage area 140 to the outside of the first baffle 1322 (i.e., the side of the first baffle 1322 facing away from the second baffle 1323), which is the requirement for ultra-wide paving operations. In related technologies, the material in the material storage area 140 is transferred to the outside of the first baffle 1322 manually, which is time-consuming and labor-intensive.

[0054] Therefore, in this embodiment of the application, when there is a need for ultra-wide paving operations, a gap 160 can be formed between the auxiliary conveying device 150 and the end of the first baffle 1322 away from the screed body 1321. The auxiliary conveying device 150 can use the gap 160 to disperse the material between the ends of the first baffle 1322, the second baffle 1323, and the material spreading device 120 (within the material stacking area 140 in actual construction) to the area on the side of the first baffle 1322 away from the second baffle 1323, thereby realizing ultra-wide paving operations. During the operation, the step of manually transferring materials is eliminated, saving time and labor.

[0055] In one embodiment, the size of the notch 160 can be adjusted by adjusting the angle between the end of the auxiliary conveying device 150 extending into the first baffle 1322, the second baffle 1323 and the end of the material distribution device 120 (within the material stacking area 140 in actual construction).

[0056] like Figure 1 As shown, the auxiliary conveying device 150 may include a connecting arm 151 and a conveying body 152. The connecting arm 151 is rotatably connected to the machine body 110, and the conveying body 152 is drive-connected to the connecting arm 151.

[0057] It should be noted that at least a portion of the conveying body 152 is located between the end of the spreading device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction). The conveying body 152 can be used to disperse the material between the end of the spreading device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction). In practical applications, the rotation of the connecting arm 151 relative to the machine body 110 and / or the rotation of the conveying body 152 relative to the connecting arm 151 can adjust the angle at which the conveying body 152 extends into the area between the end of the spreading device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction). This allows the conveying body 152 to disperse the material in different areas between the end of the spreading device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction), thereby increasing the material density between the end of the spreading device 120 and the end of the telescopic part 132. The material height uniformity within the actual construction material storage area 140; on the other hand, after the length of the telescopic part 132 extending out of the main body 131 changes, the area between the end of the material distribution device 120 and the end of the telescopic part 132 (within the actual construction material storage area 140) will change. Correspondingly, the angle between the end of the conveying body 152 extending into the material distribution device 120 and the end of the telescopic part 132 (within the actual construction material storage area 140) can be adjusted to avoid interference between the conveying body 152 and a part of the telescopic part 132.

[0058] In one embodiment, the robotic arm can be driven to rotate relative to the body 110 by a motor; and / or, the conveying body 152 can be driven to rotate relative to the robotic arm by a motor.

[0059] like Figure 1 As shown, the connecting arm 151 includes a first arm 1511 and a second arm 1512. The first arm 1511 is rotatably connected to the machine body 110, the second arm 1512 is rotatably connected to the end of the first arm 1511 away from the machine body 110, and the end of the second arm 1512 away from the first arm 1511 is rotatably connected to the conveying body 152.

[0060] It should be understood that by adjusting the included angle between the first arm 1511 and the second arm 1512, the angle range between the end of the conveying body 152 extending into the material distribution device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction) can be increased, so that the conveying body 152 can further adapt to more variations in the area size between the end of the material distribution device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction).

[0061] Figure 2 A schematic diagram of the structure of the transport body provided in an exemplary embodiment of this application from a first perspective. Figure 3This is a schematic diagram of the transport body provided as an exemplary embodiment of this application from a second perspective. Figures 1 to 3 As shown, the conveying body 152 may include a housing 1521 and a screw conveyor 1522. The housing 1521 is rotatably connected to the connecting arm 151, and the screw conveyor 1522 is rotatably connected to the housing 1521. At least a portion of the screw conveyor 1522 is located between the end of the material distribution device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction). In this way, on the one hand, when the housing 1521 rotates relative to the connecting arm 151 (and / or the connecting arm 151 drives the housing 1521 to rotate relative to the machine body 110), the screw conveyor 1522 can move synchronously with the housing 1521, thereby adjusting the angle between the end of the screw conveyor 1522 extending into the material distribution device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction); on the other hand, by rotating the screw conveyor 1522 relative to the housing 1521, the screw conveyor 1522 can disperse the material between the end of the material distribution device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction).

[0062] In one embodiment, the higher the rotational speed of the screw conveyor 1522, the higher the material dispersion efficiency between the end of the spreading device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction). When the material height between the end of the spreading device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction) is high, it is usually necessary to increase the rotational speed of the screw conveyor 1522 to achieve rapid dispersion of the material between the end of the spreading device 120 and the end of the telescopic part 132 (within the actual material stacking area 140 during construction).

[0063] like Figure 2 and Figure 3 As shown, the conveying body 152 may also include a driving member 1523. The driving member 1523 is disposed on the housing 1521 and is connected to the screw conveyor 1522. The driving member 1523 can drive the screw conveyor 1522 to rotate relative to the housing 1521.

[0064] In one embodiment, the rotational speed of the screw conveyor 1522 can be adjusted by adjusting the output power of the drive member 1523.

[0065] In one embodiment, the drive unit 1523 may include an electric motor, a hydraulic motor, a pneumatic motor, etc.

[0066] like Figures 1 to 3As shown, the housing 1521 has an opening 1524, through which the housing 1521 can cover a portion of the screw conveyor 1522. In practical applications, during the material distribution process between the end of the material distribution device 120 and the end of the telescopic part 132 of the screw conveyor 1522 (within the material stacking area 140 during actual construction), the housing 1521 can block a portion of the material distributed by the screw conveyor 1522, preventing material splashing.

[0067] like Figure 1 As shown, one part of the screw conveyor 1522 extends between the end of the material distribution device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction), and the other part of the screw conveyor 1522 is located outside the material stacking area 140. The housing 1521 covers the part of the screw conveyor located outside the material stacking area 140 to prevent material from splashing to other areas.

[0068] In one embodiment, the housing 1521 may have an opening 1524 formed on one side (for example, by removing the bottom wall of the housing 1521 to form an opening 1524); or, it may have an opening 1524 formed on both sides (for example, by removing the bottom wall of the housing 1521 and one of the side walls connected to the bottom wall to form an opening 1524); or it may have an opening 1524 formed on all three sides (for example, by removing the bottom wall of the housing 1521 and the two side walls connected to the bottom wall to form an opening 1524).

[0069] like Figure 2 and Figure 3 As shown, the conveyor body 152 may also include a support wheel 1525, which is connected to the housing 1521. It should be understood that during the adjustment of the position of the housing 1521, the support wheel 1525 can assist the housing 1521 in moving, improving the moving efficiency of the housing 1521, thereby quickly adjusting the angle between the end of the screw conveyor 1522 extending into the material distribution device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction).

[0070] In one embodiment, the number of support wheels 1525 can be one, two, three, four, etc.

[0071] Figure 4 A control block diagram of a controller, a detection element, and an auxiliary conveying device provided for an exemplary embodiment of this application. (See diagram below.) Figure 4As shown, the paver 100 may also include a detection element 170 and a controller 180. The detection element 170 can be used to detect the height of the material between the end of the spreading device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction). The controller 180 is communicatively connected to the detection element 170 and the auxiliary conveying device 150. The controller 180 can adjust the conveying speed of the auxiliary conveying device 150 (for example, adjust the rotation speed of the aforementioned screw conveyor 1522) according to the signal output by the detection element 170.

[0072] For example, in one embodiment, if the detection element 170 detects that the height of the material between the end of the spreading device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction) is greater than or equal to a height threshold, then the controller 180 can correspondingly control the conveying speed of the auxiliary conveying device 150 to increase the material dispersion efficiency and quickly reduce the material accumulation height; correspondingly, if the detection element 170 detects that the height of the material between the end of the spreading device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction) is less than a height threshold, then the controller 180 can correspondingly control the conveying speed of the auxiliary conveying device 150 to decrease.

[0073] In one embodiment, the detection element 170 may be disposed on the aforementioned first baffle 1322; or, it may be disposed on the aforementioned second baffle 1323.

[0074] In one embodiment, the detection element 170 may include a distance sensor. For example, the distance sensor is disposed on the first baffle 1322. When the material height is low, the material cannot block the detection signal of the distance sensor, and the distance value detected by the distance sensor is large. When the distance detected by the distance sensor becomes smaller (e.g., less than the distance threshold), it can be considered that the material accumulation height between the end of the fabric distribution device 120 and the end of the telescopic part 132 (within the material stacking area 140 in actual construction) is too high (exceeding the height threshold), blocking the detection signal. The controller 180 can adjust the conveying speed of the auxiliary conveying device 150 according to the signal emitted by the distance sensor at this time.

[0075] In one embodiment, the detection element 170 may further include a temperature sensor. It should be noted that the higher the material accumulation height, the higher the temperature of that accumulated material. Therefore, in practical applications, if the temperature sensor detects that the temperature of the material between the end of the fabric distribution device 120 and the end of the telescopic part 132 (within the actual material accumulation area 140 during construction) is too high (exceeding the temperature threshold), it can be considered that the material accumulation height between the end of the fabric distribution device 120 and the end of the telescopic part 132 (within the actual material accumulation area 140 during construction) is too high (exceeding the height threshold), and the controller 180 can adjust the conveying speed of the auxiliary conveying device 150 based on the signal emitted by the temperature sensor at this time.

[0076] In one embodiment, the detection element 170 may further include a camera. The camera can capture real-time images of the material accumulation between the end of the material distribution device 120 and the end of the telescopic part 132 (within the actual material accumulation area 140 during construction). By analyzing the accumulation images, the controller 180 can determine the material accumulation height relative to the road surface. In this case, if the image captured by the camera indicates that the material accumulation height between the end of the material distribution device 120 and the end of the telescopic part 132 (within the actual material accumulation area 140 during construction) is too high (exceeding a height threshold), the controller 180 can adjust the conveying speed of the auxiliary conveying device 150 accordingly.

[0077] It should be understood that the aforementioned height threshold, distance threshold, temperature threshold, etc., can all be set according to actual conditions, and this application embodiment does not impose specific limitations on them.
