Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road construction devices, in particular to a paver widening device and a paver. Background Art
[0002] In road construction, the paver is the most common construction machine, and its screed width can be freely assembled according to the designed width of the road surface. During construction, since the width of the road surface is different in the filling section and the excavation section, and the assembly of the paver screed is cumbersome, time-consuming and labor-intensive, the paver screed is often assembled in a narrow width to avoid obstruction by structures, and manual compensation is used to widen the paving width when paving a wider road section. This method increases labor consumption, there are human errors, and the construction quality is unstable. Utility Model Content
[0003] The utility model aims to provide a paver widening device and a paver to address the problem in the prior art that the width of the road surface is different between the filling section and the excavation section, and manual compensation is needed to widen the paving width when paving a wider road surface section.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A paver widening device comprises a widening plate and a base, wherein the widening plate is vertically detachably connected to the base, and the base is installed on at least one side of the paver.
[0006] The paver widening device is arranged on at least one side of the paver, and then increases the material spreading amount of the paver, and flattens the edge mixture through the widening plates on at least one of the left and right sides to complete the paving of the widened part, thereby solving the problem of width change during road paving and the problem of unstable quality caused by manual compensation; and because the widening plate is detachably connected to the base, the widening plate can be removed when constructing a narrow section to avoid obstruction of the paver by structures.
[0007] As a preferred embodiment of the utility model, at least one strip hole is provided at one end of the widened plate abutting against the base, and the strip hole is provided for detachably connecting the widened plate to the base, and the strip hole allows the connection position between the widened plate and the base to be adjusted, thereby allowing the bottom edge of the widened plate to be adaptively adjusted according to the height of the paving surface.
[0008] As a preferred solution of the utility model, at least one mounting hole is provided on the base, the position of the mounting hole matches the position of the strip hole, the mounting hole is provided for the detachable connection of the widened plate to the base, and the base and the widened plate are connected by bolts.
[0009] As a preferred solution of the present utility model, the widened plate is in a rectangular shape.
[0010] As a preferred solution of the utility model, the cross-sectional shape of the base is L-shaped, and the cross-sectional shape of the base is set to be L-shaped, one side of the L-shape is used to connect to the paver, and the other side is used to fix the widened plate.
[0011] As a preferred solution of the utility model, the width of the widening plate can be adapted according to the paving width that needs to be widened on the road surface. Since the road to be constructed each time is different, the width of the road surface is also different, so the width of the paver widening device required to be set on the paver needs to be adjusted according to the width of the road surface, and the width of the widening plate determines the width of the paver widening device, and the width of the widening plate must be able to adapt to the paving width that needs to be widened on the road surface.
[0012] As a preferred solution of the utility model, the width of the widened plate is S, 100mm≤S≤300mm, and the thickness of the widened plate is 5mm. In order to meet the general requirement of widening the paver to achieve widened paving width, the width of the widened plate is set to be greater than or equal to 100mm and less than or equal to 300mm; and in order to make the widened plate have sufficient strength, the thickness of the widened plate is set to 5mm.
[0013] As a preferred solution of the utility model, the bottom edge of the widened plate is 1-2 cm higher than the paving surface. As a normal ironing plate has a rammer, the loose paving coefficient will be smaller. The steel plate we added is not compacted with a rammer, so the loose paving coefficient will be larger. Setting it upwards means that the paving is thicker to ensure that it is consistent with the paving height in the middle after compaction, so that the bottom of the widened plate can be better adapted to the paving surface, resulting in better paving effect of the road surface.
[0014] As a preferred solution of the utility model, the widening plate and the base are both steel plate components. Setting the widening plate and the base as steel plate components, on the one hand, steel plate materials are relatively easy to obtain during road construction, and on the other hand, this will further ensure the strength of the wide plate and the base and improve the service life of the paver widening device.
[0015] A paver is provided with a paver widening device as described in any one of the above items.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0017] The paver widening device and the paver are arranged on both sides of the paver, and then the material spreading amount of the paver is increased, and the edge mixture is flattened by the widening plates on the left and right sides to complete the paving of the widened part, thereby solving the problem of width change during road paving and the problem of unstable quality caused by manual compensation, reducing labor costs, saving time, and improving the quality of road construction; and, since the widening plates are detachably connected to the base, the widening plates can be removed when constructing narrow sections to avoid obstruction of the paver by structures.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] Example 1
[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a paver widening device 1 includes a widening plate 3 and a base 4, wherein the widening plate 3 is vertically and detachably connected to the base 4, and the base 4 is installed on at least one side of the paver 2.
[0026] Those skilled in the art can understand that the paver widening device 1 is arranged on both sides of the paver 2, and then the material distribution amount of the paver 2 is increased, and the edge mixture is flattened by the widening plates 3 on the left and right sides to complete the paving of the widened part, thereby solving the problem of width change during road paving and the problem of unstable quality caused by manual compensation; and, since the widening plates 3 are detachably connected to the base 4, the widening plates 3 can be removed when constructing narrow sections to avoid obstruction of the paver 2 by structures.
[0027] In a preferred embodiment, at least one strip hole 5 is formed at one end of the widened plate 3 abutting against the base 4. Specifically, two strip holes 5 are formed at one end of the widened plate 3 abutting against the base 4, and the strip holes 5 are arranged in a row vertically; or one strip hole 5 is arranged vertically.
[0028] Those skilled in the art can understand that the strip hole 5 is provided for the detachable connection of the widened plate 3 with the base 4, and the strip hole 5 allows the connection position between the widened plate 3 and the base 4 to be adjusted, thereby allowing the bottom edge of the widened plate 3 to be adaptively adjusted according to the height of the paving surface.
[0029] In a preferred embodiment, at least one mounting hole is provided on the base 4, and the position of the mounting hole matches the position of the strip hole 5. Specifically, two mounting holes are provided on the base 4, and the size of the mounting holes matches the M12 bolt.
[0030] Those skilled in the art can understand that the installation holes are provided for the purpose of detachably connecting the widened plate 3 to the base 4, and the base 4 and the widened plate 3 are connected by bolts.
[0031] In a preferred embodiment, the widening plate 3 is rectangular in shape.
[0032] In a preferred embodiment, the cross-section of the base 4 is L-shaped.
[0033] Those skilled in the art can understand that the cross-sectional shape of the base 4 is set to be L-shaped, one side of the L-shape is used to be connected to the paver 2, and the other side is used to be fixedly connected to the widened plate 3.
[0034] In a preferred embodiment, the width of the widening plate 3 can be adapted according to the paving width that needs to be widened on the road surface.
[0035] Those skilled in the art can understand that since the road to be constructed each time is different and the width of the road surface is also different, the width of the paver widening device 1 required to be set on the paver 2 needs to be adjusted according to the width of the road surface, and the width of the widening plate 3 determines the width of the paver widening device 1, and the width of the widening plate 3 must be able to adapt to the paving width that needs to be widened according to the road surface.
[0036] In a preferred embodiment, the width of the widened plate 3 is S, 100mm≤S≤300mm, and the thickness of the widened plate 3 is 5mm.
[0037] Those skilled in the art can understand that in order to meet the general requirement of widening the paver 2 to achieve a widened paving width, but the widening plate 3 is too large, which will cause the support to be unable to withstand deformation and lead to poor paving quality. The width of the widening plate 3 is set to be greater than or equal to 100 mm and less than or equal to 300 mm; and in order to make the widening plate 3 have sufficient strength, the thickness of the widening plate 3 is set to 5 mm.
[0038] In a preferred embodiment, the bottom edge of the widened plate 3 is 1-2 cm higher than the paving surface.
[0039] Those skilled in the art can understand that, because a normal ironing plate has a rammer, the loose paving coefficient will be smaller. The steel plate we added is not compacted by a rammer, so the loose paving coefficient will be larger. Setting it upwards means paving thicker to ensure that it is consistent with the paving height in the middle after compaction, so that the bottom of the widened plate 3 can be better adapted to the paving surface, resulting in a better paving effect on the road surface.
[0040] In a preferred embodiment, the widening plate 3 and the base 4 are both steel plate components.
[0041] Those skilled in the art can understand that setting the widening plate 3 and the base 4 as steel plate components, on the one hand, is that steel plate materials are relatively easy to obtain during road construction, and on the other hand, this will further ensure the strength of the widening plate 3 and the base 4 and improve the service life of the paver widening device 1.

[0044] Example 3
[0045] like Figure 1 , Figure 2 , Figure 3 As shown, a specific usage of a paver widening device 1.
[0046] Before the road paving construction, the base 4 is welded to a suitable position between the two ends of the paver 2 near the lower edge by using an electric welder.
[0047] When paving a wider road section, operators at both ends of the paver 2 use bolts to connect and install the widening plate 3 on the base 4, and adjust the bottom edge height to be 1-2 cm higher than the paving surface.
[0048] The amount of material distributed at the edge of the paver 2 is increased so that part of the mixed material overflows from the edge of the paver 2, and the paver widening device 1 is used to flatten the overflowing mixed material.
[0049] When the construction reaches a narrow section, operators at both ends of the paver 2 remove the widening plate 3 to avoid obstruction of the paver 2 by the structure.
[0050] In addition, in the description of the technical solution of the utility model, unless otherwise clearly specified / defined / restricted, the terms "set", "install", "connect", "connected", "provided with", "laid", and "arranged" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, and can be welding, riveting, bolting, threading, and other commonly used connection means in the field. This connection can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal communication of two components.
[0051] In addition, if the terms "horizontal", "vertical", "overhanging", "parallel" and the like appear, it does not mean that the corresponding devices / components / elements are required to be absolutely horizontal or vertical or overhanging or parallel, but may be slightly tilted or have deviations. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but may be slightly tilted. Alternatively, it can be simplified to mean that the corresponding devices / components / elements are set in directions such as "horizontal", "vertical", "overhanging", "parallel", etc., and can have an error / deviation of ±10% relative to the corresponding direction setting, more preferably an error / deviation within ±8%, more preferably an error / deviation within ±6%, more preferably an error / deviation within ±5%, and more preferably an error / deviation within ±4%.
