Description

TECHNICAL FIELD

[0001] The present application relates to a curb edge asphalt compaction tool. BACKGROUND

[0002] At present, in the construction of municipal road asphalt pavement, the curb edge design is often arc-shaped at the pavement turning area, turning lane, bus stop, parking area and other positions, as shown in Figure 7 In these narrow areas, since the paver cannot work, manual paving is generally used, and the flatness of manual paving is not as good as that of the paver. The rolling procedure after paving is very important. The traditional steel wheel roller and rubber tire roller cannot perform asphalt compaction work. Generally, a flat tamper is used for tamping work at such positions. However, the bottom plate of the flat tamper is generally rectangular, and there is a problem of not being able to stick to the edge for a circular arc-shaped edge with a small radius, which often causes the asphalt in the curb edge area to not be compacted, resulting in poor pavement flatness, compaction, aesthetics and quality. Figure 8 In addition, for a parallelogram inclined parking space, there is an acute angle area in the curb edge, as shown in The flat tamper cannot tamp the acute angle area. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a curb edge asphalt compaction tool which can effectively compact the asphalt at the circular arc-shaped edge of the municipal road asphalt pavement and the acute angle of the parallelogram inclined parking space.

[0004] To solve the above technical problems, the present application provides a curb edge asphalt compaction tool, which comprises a flat tamper, the flat tamper comprising a horizontal bottom plate, a tamper body provided on the bottom plate and an operating handle, at least two groups of front and rear spaced connection assemblies being provided on the bottom plate at a position close to the edge of the left and right sides, each group of connection assemblies comprising two left and right spaced connection blocks, a channel being provided in the middle of each connection block and extending through the connection block in the left and right directions, and a first threaded hole being provided on the upper side of each connection block corresponding to the channel and extending through the connection block in the vertical direction and communicating with the channel.

[0005] The tamper body is provided with a accessory box, and the accessory box is provided with a plurality of R-angle pressing plates and a plurality of acute angle pressing plates.

[0006] Each R-angle pressing plate is a horizontally arranged long strip plate body, the left and right side edges of the R-angle pressing plate are straight edges running from front to back, and the other side edges are circular arc edges, the side edge of the R-angle pressing plate closer to the straight edge is the inner side, and the side edge closer to the circular arc edge is the outer side, the upper side of the R-angle pressing plate is provided with a first connecting rod extending horizontally inwards, the number and size of the first connecting rod on each R-angle pressing plate are matched with the number of the connecting assemblies on the bottom plate and the size of the channel on the connecting block, and each first connecting rod is provided with a second threaded hole corresponding to the first threaded hole of the two connecting blocks in the connecting assembly.

[0007] Each acute-angle pressing plate is a horizontally arranged isosceles triangular plate body, the length direction of the middle line of the isosceles triangular base edge of the acute-angle pressing plate runs in the left and right direction, the side edge of the acute-angle pressing plate closer to the base edge is the inner side, and the side edge closer to the vertex angle is the outer side, the upper side of the acute-angle pressing plate is provided with a second connecting rod extending horizontally inwards, the number and size of the second connecting rod on each acute-angle pressing plate are matched with the number of the connecting assemblies on the bottom plate and the size of the channel on the connecting block, and each second connecting rod is provided with a third threaded hole corresponding to the first threaded hole of the two connecting blocks in the connecting assembly.

[0008] For the sake of simplicity, the road kerb edge asphalt compacting tool described in the present application is referred to as the tool hereinbelow.

[0009] The use method and advantages of the tool:

[0010] When the circular arc edge with a small radius needs to be asphalt compacted, the R-angle pressing plate corresponding to the arc is taken out from the accessory box, and then the R-angle pressing plate is placed on the side edge of the bottom plate provided with the connecting assembly, so that the first connecting rod corresponds to the channel of the two connecting blocks of the connecting assembly, and is fixed with the bolt matched with the first threaded hole and the second threaded hole, at this time, the flat rammer is started to compact the circular arc edge, and the appropriate R-angle pressing plate can be selected according to the curvature of the circular arc edge;

[0011] When the acute-angle position of the parallelogram inclined parking space needs to be asphalt compacted, the acute-angle pressing plate corresponding to the model is taken out from the accessory box, and then the acute-angle pressing plate is placed on the side edge of the bottom plate provided with the connecting assembly, so that the second connecting rod corresponds to the channel of the two connecting blocks of the connecting assembly, and is fixed with the bolt matched with the first threaded hole and the third threaded hole, at this time, the flat rammer is started to compact the acute-angle position of the parallelogram inclined parking space, and the appropriate acute-angle pressing plate can be selected according to the specific shape of the acute-angle region.

[0012] The R-angle pressing plate and the acute-angle pressing plate are stored in the accessory box when not in use, which not only prevents loss and facilitates transportation, but also increases the self-weight of the flat rammer, thereby improving the compacting effect.

[0013] In order to achieve better use of the tool, the preferred scheme is as follows:

[0014] As preferred, the circular arc edge of the R-angle pressing plate is provided with an upward first flange, and the edge corresponding to the two waist lines of the isosceles triangle of the acute-angle pressing plate is provided with an upward second flange.

[0015] The first flange and the second flange facilitate the flat-plate rammer to compact the asphalt while advancing, and play a guiding role. In addition, the flanges can increase the edge strength of the R-angle pressing plate and the acute-angle pressing plate, and prevent damage to the R-angle pressing plate and the acute-angle pressing plate during compaction.

[0016] As preferred, the acute-angle pressing plate is provided with a vertical screw rod near the top corner of the isosceles triangle, the screw rod is screwed to the acute-angle pressing plate, a plurality of annular weight plates are sleeved on the screw rod, the weight plates are stacked in sequence along the vertical direction, and a fixing nut is screwed to the upper part of the screw rod, and the lower side of the fixing nut is in close contact with the uppermost weight plate.

[0017] The installation of the screw rod and the weight plates can increase the weight of the acute-angle pressing plate. Since the center of the acute-angle pressing plate is far away from the body of the rammer, the weight of the body of the rammer cannot act on the acute-angle pressing plate. By arranging the weight structure near the top corner of the isosceles triangle of the acute-angle pressing plate, the compaction effect can be improved. In addition, the screw rod, the weight plates, and the nut are detachable loose structures, which can be stored in a accessory box during daily transportation. BRIEF DESCRIPTION OF DRAWINGS
