Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Example

[0025] At present, in order to make the concrete pavement texture increase the friction of the pavement, improve the grip of vehicles and pedestrians under slippery conditions, and reduce traffic accidents caused by slippery pavement, a pavement texture construction device is needed to carry out the construction of the asphalt concrete pavement of municipal roads. However, the municipal asphalt concrete pavement construction device of the prior art has the following disadvantages during use:

[0026] Generally, the connected multiple grain drawing claws 21 are pulled by a hand-held rod 1, and the grain drawing operation is performed on the surface of the concrete pavement. However, the distance between the multiple grain drawing claws 21 is fixed, and the distance between the multiple grain drawing claws 21 cannot be adjusted according to actual use requirements, resulting in a fixed distance between the drawn grains, which cannot meet the construction requirements of different concrete pavements;

[0027] To do this, see Figure 1-4 The utility model provides a municipal road asphalt concrete pavement construction device, comprising: a hand-held rod 1, an adjusting rod 3 is slidably inserted into the inner side of the hand-held rod 1, a connecting plate 2 is fixedly connected to the front end of the hand-held rod 1, an end of the adjusting rod 3 away from the connecting plate 2 is fixedly connected to a handle a31, a hand screw a32 is movably inserted into the position of the hand-held rod 1 away from the connecting plate 2, a plurality of screw holes a321 matched with the hand screw a32 are opened on the outer wall of the adjusting rod 3, a plurality of equally spaced drawing claws 21 are installed at the bottom end of the connecting plate 2, and the top end of the middle drawing claw 21 among the plurality of drawing claws 21 is fixedly connected to the middle part of the bottom end of the connecting plate 2;

[0028] It also includes a spacing synchronization adjustment component 4, which is installed on the top of the hand-held rod 1 and is connected to the connecting plate 2, the handle a31 and the top ends of the plurality of drawing claws 21;

[0029] After the adjusting rod 3 is telescopically adjusted and fixed on the hand-held rod 1 , the spacing synchronous adjustment component 4 can simultaneously and conveniently adjust the spacing between every two adjacent two grain drawing claws 21 among the plurality of grain drawing claws 21 .

[0030] Among them, the setting of the hand screw a32 can enable the adjusting rod 3 to be locked and fixed after adjusting the telescopic length in the hand-held rod 1.

[0031] Further as Figure 1-4 As shown, it is worth explaining in detail that the spacing synchronization adjustment component 4 includes two symmetrically arranged slide grooves opened on the connecting plate 2, and each slide groove is slidably connected with a plurality of equidistantly arranged sliders 41, and the vertical cross-sections of the sliders 41 are I-shaped structures. The bottom ends of the sliders 41 are fixedly connected to the top ends of the corresponding drawing claws 21, and a transmission column 42 is fixedly connected to the outer side of each slider 41. A guide column 43 is fixedly connected to the middle part of the top end of the connecting plate 2. A plurality of transmission columns 42 and guide columns 43 are movably sleeved on the outer sides thereof. The bottom ends of the synchronization plates 44 are fixedly connected with two symmetrically arranged guide blocks 45, and the guide blocks 45 are slidably sleeved on the outer sides of the slide rods 46, and the slide rods 46 are fixedly connected to the outer sides of the connecting plate 2.

[0032] The guide column 43 and the transmission column 42 have the same diameter.

[0033] Further as Figure 1-4 As shown, it is worth specifically explaining that, in order to enable the adjusting rod 3 to adjust the telescopic length in the hand-held rod 1, the distance between the multiple drawing claws 21 can be adjusted manually and synchronously, so a guide straight groove 431 matching with the guide column 43 is provided through the middle of the synchronous plate 44, and a plurality of transmission grooves 421 are provided on both sides of the guide straight groove 431. The multiple transmission grooves 421 provided on each side are based on the guide straight groove 431, and the inclination angles of each side from near to far are arranged in sequence from large to small, and a moving plate 44 is fixedly connected to the middle of the top of the synchronous plate 44. A movable block 47 is threadedly connected with a one-way screw 48, one end of the one-way screw 48 is fixedly connected with a spline sleeve 49, the spline sleeve 49 is rotatably connected to the outside of the hand-held rod 1 through two bearing seats a, a spline shaft 410 is movably inserted in the spline sleeve 49, one end of the spline shaft 410 away from the one-way screw 48 is rotatably connected to the top of the handle a31 through the bearing seat b, and a handle b411 is fixedly connected to the outside of the extension part of one end, and a hand screw b412 is also threadedly connected to the handle b411, and one end of the hand screw b412 is pressed against the outside of the bearing seat b after being locked.

[0034] Among them, the guide straight groove 431 and the synchronous plate 44 are vertically arranged at 90 degrees, and the width of the guide straight groove 431 is equal to the diameter of the guide column 43, which effectively avoids the movement of the synchronous plate 44 during movement. Secondly, the width of the multiple transmission grooves 421 on each side is equal to the diameter of the transmission column 42, and the hand-screwed screw b412 is locked to prevent the spline shaft 410 from moving when the device is manually constructed, thereby preventing the distance between its multiple drawing claws 21 from changing.

[0035] In summary: when using the municipal road asphalt concrete pavement construction device, first, the length of the hand-held rod 1 can be adjusted according to the width of the asphalt concrete pavement, and the hand-screw a32 can be loosened to make the hand-screw a32 disengage from its corresponding screw hole a321, so that the adjusting rod 3 can be pulled and extended by the handle a31, and at the same time, the spline shaft 410 is driven to extend and adjust the inner side of the spline sleeve 49. After the adjustment is completed, the hand-screw a32 can be locked. Secondly, when it is necessary to adjust the spacing between the multiple drawing claws 21, When performing synchronous adjustment, the hand-tightening screw b412 can be loosened and the spline shaft 410 can be rotated by the handle b411, so that the spline sleeve 49 drives the one-way screw 48 to rotate. Since the one-way screw 48 is threadedly connected to the moving block 47, the synchronous plate 44 can move on the top of the connecting plate 2, and cooperate with the guide straight groove 431 and the multiple transmission grooves 421 on both sides, so that the distance between each adjacent two drawing claws 21 among the multiple drawing claws 21 can be adjusted to the same, thereby meeting different concrete pavement construction requirements.
