Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, and in particular to a screed and a paver. Background Technology

[0002] As a construction equipment for paving road materials, a paver consists of different systems working together to complete the paving operation. During the paving operation, the paver uses a screed to smooth and compact the road surface.

[0003] Currently, screeds consist of a base plate and heating elements mounted on the base plate. The base plate is used to contact the road material, and the heating elements are used to heat the base plate to prevent the road material from sticking to the base plate and causing uneven paving. The heating elements are generally coiled back and forth, and the coiled heating elements are then fixed to the base plate.

[0004] However, the heating element heats unevenly on both sides of the base plate along its length. When the paver is in operation, material tends to stick to the edges of the base plate on both sides, resulting in roughness on the paved road surface and substandard road smoothness. Utility Model Content

[0005] Based on this, this application provides a part and device to solve the problem of uneven heating of the heating element on both sides of the base plate in the related art.

[0006] In a first aspect, embodiments of this application provide an ironing board, including a base plate and a heating strip mounted on one side of the base plate;

[0007] The heating strip is installed on the base plate;

[0008] The heating strip includes a first heating section, a second heating section and a third heating section connected in sequence. The first heating section and the third heating section are located on opposite sides of the base plate along its length. Both the first heating section and the third heating section extend along the width of the base plate. The second heating section is located on one side of the base plate along its width and extends along the length of the base plate.

[0009] The base plate has a first center line that extends along the length of the base plate, and the two ends of the heating strip are located on the side of the first center line away from the second heating section.

[0010] In one possible implementation, the heating strip further includes a fourth heating section, which is located on the side of the base plate away from the second heating section in the width direction of the base plate; one end of the fourth heating section is connected to the end of the first heating section away from the second heating section, and the fourth heating section extends along the length direction of the base plate.

[0011] In one possible implementation, the heating strip further includes a fifth heating segment, a sixth heating segment, a seventh heating segment, and an eighth heating segment connected in sequence. The end of the fifth heating segment away from the sixth heating segment is connected to the end of the third heating segment away from the second heating segment. The extension directions of the fifth, seventh, and eighth heating segments are all parallel to the extension direction of the second heating segment. The fifth heating segment is located on the side of the base plate away from the second heating segment. The seventh and eighth heating segments are located between the second and fourth heating segments. The extension direction of the sixth heating segment is parallel to the extension direction of the third heating segment. The sixth heating segment is located on the side of the third heating segment facing the first heating segment.

[0012] In one possible implementation, two adjacent heating sections are connected by a transition section, which is arc-shaped with a radius of 30mm-50mm.

[0013] In one possible implementation, the second heating section, the seventh heating section, the eighth heating section, and the fourth heating section are arranged at equal intervals.

[0014] In one possible implementation, the eighth heating section has a wiring section at the end facing the third heating section.

[0015] In one possible implementation, there are multiple heating bars, all of which have the same shape and are arranged sequentially from the inside out.

[0016] In one possible implementation, the ironing board also includes a pressure plate, which is placed on and fixed to the base plate, and a heating strip is held between the base plate and the pressure plate.

[0017] In one possible implementation, a stud is mounted on the base plate, with its end passing through a pressure plate. A nut is mounted on the stud, and the nut abuts against the side of the pressure plate opposite to the base plate.

[0018] Secondly, embodiments of this application provide a paver, including the aforementioned screed.

[0019] The screed and paver provided in this application include a base plate and a heating strip mounted on one side of the base plate. The heating strip is disposed on the base plate. The heating strip includes a first heating section, a second heating section, and a third heating section connected in sequence. The first and third heating sections extend along the width direction of the base plate, and the second heating section extends along the length direction of the base plate. In use, the first and third heating sections are located on the left and right sides of the base plate, respectively, and the second heating section is located on the front side of the base plate. The heating strip forms a complete and continuous heating unit on the left, right, and front sides of the base plate, improving the heating effect at the edge of the base plate and ensuring uniform heating on the left, right, and front sides. The two ends of the heating strip are located on the side away from the second heating section from the first center line. Since there is a gap between the end of the heating strip and the main body of the heating strip, the rear side of the base plate is relatively insensitive to temperature. Placing the two ends of the heating strip close to the rear side of the base plate can reduce the impact of the aforementioned gap on the paving effect and help ensure paving quality.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0034] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0035] In the prior art, a screed includes a base plate and a heating element mounted on the base plate. The base plate is used to contact the road material, and the heating element is used to heat the base plate to prevent the road material from sticking to the base plate, which would result in an uneven paved surface. Figure 1As shown, to reduce costs, heating strips 200 are generally used as heating elements. The heating strips 200 typically coil back and forth along the length of the base plate 100, forming an approximate "S" shape, and are then fixed to the base plate 100. However, the heating strips bend on both sides of the base plate with a large radius of curvature, resulting in discontinuity and low heating density in the heating element's length direction on both sides, leading to uneven heating. During paver operation, material tends to stick to the edges of the base plate on both sides, causing roughness on the paved surface and resulting in substandard road surface smoothness.

[0036] After repeated consideration and verification, the inventors discovered that reshaping the heating strip on the base plate to ensure its continuity on the left, right, and front sides guarantees uniform heating across these areas. Positioning the heating strips closer to the rear of the base plate reduces the impact of the gap between the ends and the main body on the paving effect, thus improving paving quality.

[0037] In view of this, the inventors designed a screed and a paver, wherein the heating strip of the screed is set on the base plate. The heating strip includes a first heating section, a second heating section, and a third heating section connected in sequence. The first and third heating sections are located on the left and right sides of the base plate, respectively, and both heating sections extend in the front-to-back direction. The second heating section is located on the front side of the base plate and extends in the left-to-right direction. The two ends of the heating strip are set behind the center line of the base plate. This ensures uniform heating on the left, right, and front sides of the base plate and helps to ensure paving quality.

[0038] The technical solutions of the screed and paver provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0039] Reference Figures 2 to 4 As shown in the embodiment of this application, the ironing board includes a base plate 100 and a heating strip 200 mounted on one side of the base plate 100. The heating strip 200 is disposed on the base plate 100. Optionally, the heating strip 200 can be fixed to the base plate 100 by means of a snap fastener or by means of a limiting piece cooperating with a fastener.

[0040] The heating strip 200 includes a first heating section 210, a second heating section 220 and a third heating section 230 connected in sequence. The first heating section 210 and the third heating section 230 are located on opposite sides of the base plate 100 in the length direction. Both the first heating section 210 and the third heating section 230 extend along the width direction of the base plate 100. The second heating section 220 is located on one side of the base plate 100 in the width direction and extends along the length direction of the base plate 100.

[0041] Among them, the length direction of the base plate 100 is... Figures 2-4 The direction indicated by the X-axis is the width direction of the base plate 100. Figures 2-4 The direction indicated by the Y-axis. The first heating section 210, the second heating section 220, and the third heating section 230 are formed by bending the heating strip 200. The overall shape of the heating strip 200 is approximately rectangular, with the first heating section 210, the second heating section 220, and the third heating section 230 located at the edges of the rectangle. When the ironing board is in use, the first heating section 210 and the third heating section 230 are located on the left and right sides of the base plate 100, respectively, and the second heating section 220 is located on the front side of the base plate 100. The first heating section 210 and the third heating section 230 make the heating strip 200 continuous on the left and right sides of the base plate 100, respectively, while the second heating section 220 makes the heating strip 200 continuous on the front side of the base plate 100. Those skilled in the art can set the spacing between the first heating section 210, the second heating section 220, and the third heating section 230 and the adjacent edges of the base plate 100 as needed, and no unique limitation is made here. Optionally, the length of the second heating section 220 can be the same as the length of the third heating section 230.

[0042] The base plate 100 has a first center line L1, which extends along the length of the base plate 100. The two ends of the heating strip 200 are located on the side of the first center line L1 away from the second heating section 220.

[0043] The first centerline L1 is the length centerline of the base plate 100. When the ironing board is in use, the two ends of the heating strip 200 are located on the rear side of the base plate 100. It is worth noting that, to facilitate the placement of the heating strip 200, there is a gap between the two ends of the heating strip 200 and its main body. This gap causes the heating strip 200 to be discontinuous at both ends. When the ironing board is in use, the rear side of the base plate 100 is relatively less sensitive to temperature than other areas. Placing the two ends of the heating strip 200 on the rear side of the base plate 100 reduces the impact of the gap at the ends of the heating strip 200 on the paving effect.

[0044] In one possible implementation, the first heating section 210 is located on the left side of the base plate 100, and the third heating section 230 is located on the right side of the base plate 100. In another possible implementation, the first heating section 210 is located on the right side of the base plate 100, and the third heating section 230 is located on the left side of the base plate 100. That is to say, the winding path of the heating strip 200 can be mirrored left and right.

[0045] The screed provided in this embodiment has a first heating section 210 and a third heating section 230 located on the left and right sides of the base plate 100, respectively, and a second heating section 220 located on the front side of the base plate 100. The heating strip 200 is a complete continuous heating unit on the left, right, and front sides of the base plate 100, improving the heating effect at the edges of the base plate 100 and ensuring uniform heating on the left, right, and front sides. The two ends of the heating strip 200 are located on the side of the first centerline away from the second heating section 220. Since there is a gap between the ends of the heating strip 200 and its main body, and the rear side of the base plate 100 is relatively insensitive to temperature, placing the two ends of the heating strip 200 close to the rear side of the base plate 100 can reduce the impact of this gap on the paving effect and help ensure paving quality.

[0046] Furthermore, the heat from the heating strip 200 can be directly transferred to the base plate 100, resulting in high heating efficiency. The heating strip 200 does not have multiple bends on either side of the base plate 100, ensuring uniform heating of the edge areas of the base plate 100.

[0047] In one embodiment, such as Figures 2-4 As shown, the heating strip 200 also includes a fourth heating section 240. In the width direction of the base plate 100, the fourth heating section 240 is located on the side of the base plate 100 away from the second heating section 220. One end of the fourth heating section 240 is connected to the end of the first heating section 210 away from the second heating section 220, and the fourth heating section 240 extends along the length direction of the base plate 100.

[0048] The fourth heating section 240 is also formed by bending the heating strip 200. When the ironing board is in use, the fourth heating section 240 is located in the rear area of ​​the base plate 100. Schematic, the length of the fourth heating section 240 is less than the length of the second heating section 220, thus the fourth heating section 240 does not overlap with the third heating section 230. Figures 2-4 As shown, the end of the fourth heating section 240 facing the third heating section 230 is one end of the heating bar 200.

[0049] In this structure, the heating strip 200 can heat the rear area of ​​the base plate 100 through the fourth heating section 240. The fourth heating section 240 is a relatively complete heating unit, which can make the rear area of ​​the base plate 100 have a better heating effect.

[0050] In a specific embodiment, such as Figure 2 and Figure 3 As shown, the heating strip 200 also includes a fifth heating section 250, a sixth heating section 260, a seventh heating section 270, and an eighth heating section 280 connected in sequence. The fifth heating section 250, the sixth heating section 260, the seventh heating section 270, and the eighth heating section 280 are also formed by bending the heating strip 200.

[0051] The end of the fifth heating section 250 that is away from the sixth heating section 260 is connected to the end of the third heating section 230 that is away from the second heating section 220. Figure 2 and Figure 3 As shown, the fourth heating section 240, the first heating section 210, the second heating section 220, the third heating section 230, the fifth heating section 250, the sixth heating section 260, the seventh heating section 270 and the eighth heating section 280 are connected in sequence.

[0052] The fifth heating section 250, the seventh heating section 270, and the eighth heating section 280 all extend parallel to the extension direction of the second heating section 220, with the fifth heating section 250 located on the side of the base plate 100 away from the second heating section 220. That is, the fifth heating section 250, the seventh heating section 270, and the eighth heating section 280 extend along the length of the base plate 100. Understandably, when the ironing board is in use, the fifth heating section 250 and the fourth heating section 240 together heat the rear area of ​​the base plate 100.

[0053] The seventh heating section 270 and the eighth heating section 280 are located between the second heating section 220 and the fourth heating section 240. The extension direction of the sixth heating section 260 is parallel to the extension direction of the third heating section 230. The sixth heating section 260 is located on the side of the third heating section 230 facing the first heating section 210.

[0054] Specifically, the second heating section 220, the seventh heating section 270, the eighth heating section 280, and the fourth heating section 240 are arranged at intervals along the width direction of the base plate 100. The lengths of the seventh heating section 270 and the eighth heating section 280 are both shorter than the length of the second heating section 220. The end of the eighth heating section 280 facing the third heating section 230 is the other end of the heating strip 200. When the third heating section 230 is located on the right side of the base plate 100, the sixth heating section 260 is arranged close to the right side of the base plate 100; when the third heating section 230 is located on the left side of the base plate 100, the sixth heating section 260 is arranged close to the left side of the base plate 100. Those skilled in the art can set the interval between the third heating section 230 and the sixth heating section 260 as needed, and no unique limitation is made here.

[0055] With the above settings, the area where the heating strip 200 is set can be heated evenly, and the two ends of the heating strip 200 can be set close to the rear side of the base plate 100.

[0056] In one possible implementation, such as Figures 2-4 As shown, two adjacent heating sections are connected by a transition section 290, which is arc-shaped with a radius of 30mm-50mm.

[0057] In other words, adjacent heating sections are transitioned by a rounded corner with a radius greater than or equal to 30 mm and less than or equal to 50 mm. The transition section 290 can prevent large stress concentrations in the heating strip 200 between adjacent heating sections and prevent damage to the heating strip 200 during bending.

[0058] For example, the radius of the arc can be 30mm, 35mm, 40mm, 45mm, or 50mm, etc., and is not limited to a single value. When the radius of the arc formed by the transition section 290 is less than 30mm, the stress between two adjacent heating sections of the heating strip 200 may be relatively large, and the heating strip 200 may be damaged during bending. When the radius of the arc formed by the transition section 290 is greater than 50mm, the transition section 290 occupies a large space, resulting in a shorter heating section and affecting the heating effect of the heating section. In other words, by limiting the radius of the arc to 30mm-50mm, the reliability of the heating strip 200 can be guaranteed while also ensuring the heating effect of the heating section.

[0059] like Figure 2 and Figure 3 As shown, the second heating section 220, the seventh heating section 270, the eighth heating section 280, and the fourth heating section 240 are arranged at equal intervals. The spacing between any two adjacent heating sections is set according to the interval between the second heating section 220 and the fourth heating section 240, and is not limited to a single value here.

[0060] Understandably, the above settings can ensure that the heating strip 200 can evenly heat the area between the second heating section 220 and the fourth heating section 240.

[0061] In one possible implementation, such as Figure 2 and Figure 3 As shown, a wiring section 201 is provided at one end of the eighth heating section 280 facing the third heating section 230.

[0062] The heating strip 200 is an electric heating element, and the wiring part 201 can be a connector at the end of the heating strip 200. The heating strip 200 can be connected to an external power source through the wiring part 201 to heat the base plate 100.

[0063] Those skilled in the art will understand that the base plate 100 of the ironing board is fixed to the frame for ironing operations. For example Figure 2 and Figure 3 As shown, a connecting post 400 can be provided on the base plate 100. The end of the connecting post 400 away from the base plate 100 can be threaded. The base plate 100 can be fixed to the frame by the connecting post 400 and the nut installed on the connecting post 400.

[0064] In this embodiment, the wiring part 201 is located at one end of the eighth heating section 280 facing the third heating section 230, which allows the wiring part 201 to have a certain distance from the rear edge of the base plate 100, making it less likely for the wiring part 201 to interfere with the frame, and facilitating the assembly of the base plate 100.

[0065] In another possible implementation, such as Figure 4 As shown, there are multiple heating bars 200, all of which have the same shape and are arranged in a ring from the inside out.

[0066] The number of heating bars 200 can be two, three, or four, etc., and is not limited to a single number. Each heating bar 200 includes a first heating section 210, a second heating section 220, a third heating section 230, and a fourth heating section 240. It is understood that the first heating sections 210 of the multiple heating bars 200 are arranged in parallel and spaced apart, the second heating sections 220 of the multiple heating bars 200 are arranged in parallel and spaced apart, the third heating sections 230 of the multiple heating bars 200 are arranged in parallel and spaced apart, and the fourth heating sections 240 of the multiple heating bars 200 are arranged in parallel and spaced apart.

[0067] With the above settings, the base plate 100 can be heated evenly by multiple heating bars 200.

[0068] In one embodiment, the ironing board further includes a pressure plate (not shown), which covers and is fixed to the base plate 100, and the heating strip 200 is clamped between the base plate 100 and the pressure plate.

[0069] For example, the shape and size of the pressure plate can match the base plate 100. The pressure plate and the base plate 100 can be fixed together by clamps or other fasteners. When the heating strip 200 is provided with a wiring portion 201 at its end, the wiring portion 201 passes through the pressure plate so that an external power source can supply power to the heating strip 200.

[0070] In one possible implementation, a limiting groove can be provided on the side of the base plate 100 facing the pressure plate. The shape and size of the limiting groove match the main body of the heating strip 200, and the main body of the heating strip 200 can be embedded in the limiting groove.

[0071] In this embodiment, the heating strip 200 can be reliably fixed on the base plate 100 by the cooperation between the pressure plate and the base plate 100, ensuring that the heating strip 200 can reliably heat the base plate 100.

[0072] like Figure 4As shown, in one specific embodiment, a stud 300 is mounted on the base plate 100, with one end of the stud 300 passing through a pressure plate. The stud 300 can be located between the heating strip 200 and the edge of the base plate 100. One end of the stud 300 is fixed to the base plate 100, and the other end passes through the pressure plate. The number of studs 300 and their specific positions on the pressure plate can be configured as needed and are not limited to a single configuration.

[0073] A nut (not shown) is installed on the stud 300, and the nut abuts against the side of the pressure plate away from the base plate 100.

[0074] In this embodiment, the pressure plate can be positioned on the base plate 100 by the engagement between the stud 300 and the corresponding nut, thereby reliably fixing the heating strip 200 on the base plate 100.

[0075] This application also provides a paver, including the screed described above.

[0076] The paver provided in this application uses the aforementioned screed, which ensures uniform heating of the left, right, and front sides of the base plate 100. During operation, material does not easily stick to the edges of the left and right sides of the base plate 100, thus ensuring the paving effect and the smoothness of the road surface.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
