[0002] Bridge pavement paving refers to the laying of pavement materials on the foundation structure of a bridge, and a bridge pavement paver is a mechanical equipment specially used for pavement paving operations in bridges and other road projects. Its main function is to evenly spread concrete or asphalt materials on the pavement of the bridge to form a flat and solid pavement structure. Due to the uneven accumulation of pavement paving materials, as the device moves forward a certain distance, the paving materials on the front side of the device will accumulate too much and easily overflow to the middle section of the device, thereby affecting the normal operation of the device drive components. As a result, the existing bridge pavement paver requires continuous manual intervention by staff to use a shovel to remove and shift the paving materials on the front side of the device during paving operations. The overall operation process is cumbersome and the paving efficiency is low. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0034] like Figures 1 to 6 As shown, the bridge pavement paver provided by the embodiment of the present utility model includes a paver body 1, an auger shaft 2, an auxiliary pushing mechanism 3, a portable assembly mechanism 4 and an auxiliary moving mechanism 5;

[0035] Two sets of pressure rollers are symmetrically installed inside the paver body 1, and an auger shaft 2 is provided on the side of the pressure rollers at the forward end of the paver body 1;

[0036] The paver body 1 is provided with two sets of support bases, and the upper part of the two sets of support bases is connected to an auxiliary pushing mechanism 3, and the auxiliary pushing mechanism 3 is oriented at the forward end of the entire device;

[0037] A portable assembly mechanism 4 is connected between the auger shaft 2 and the two supporting bases of the paver body 1. The spiral blades arranged on the outside of the auger shaft 2 are symmetrically arranged in two groups, and the spiral directions of the two groups of spiral blades are arranged in opposite directions.

[0038] An auxiliary moving mechanism 5 for pushing the device forward is connected to the top of the two supporting bases of the paver body 1.

[0039] It should be noted that when the device is in use, the paver body 1 is composed of a common mechanical structure on the market, and the specific operation can be carried out in accordance with the existing operating technical standards. Here, two groups of spiral blades are symmetrically arranged, and the spiral directions of the two groups of spiral blades are set in opposite directions, so that the auger shaft 2 can transport and level the paving material on the road surface when rotating, thereby achieving the effect of uniform paving. At the same time, the auger shaft 2 is used in the front to level and transport the paving material, and the pressure roller at the rear of the device automatically flattens the filler, and the road paving work can be completed.

[0040] In this embodiment, the auxiliary pushing mechanism 3 includes a pushing box 31, a positioning base plate 32, a positioning threaded hole 33, a docking threaded hole 34 and a positioning bolt 35;

[0041] The outer walls of the bottom ends of the two support bases of the paver body 1 are connected to a push box 31, and the outer walls of the sides of the push box 31 at the bottom end are symmetrically provided with positioning bottom plates 32;

[0042] The bottom outer wall of the positioning base plate 32 is symmetrically provided with positioning threaded holes 33, and the top outer wall of the supporting base is correspondingly provided with two sets of docking threaded holes 34;

[0043] The positioning threaded hole 33 and the docking threaded hole 34 are threadedly mounted with the positioning bolt 35 .

[0044] The cam 32 is then screwed onto the top of the support frame 31 so that the cam 32 can be screwed onto the support frame 31.

[0045] In this embodiment, the side outer wall of the pushing box 31 located at the forward end of the device is set to an open structure, and the bottom outer wall of the pushing box 31 is set to an arc structure.

[0046] It should be noted that the above design allows excess paving material to enter the push box 31 more smoothly during the movement of the device, and the blocking effect of the push box 31 will not directly overflow into the driving components of the device, thereby achieving better protection effect.

[0047] In this embodiment, the portable assembly mechanism 4 includes a mounting shaft 41, a supporting shaft 42, an interference block 43, an interference slot 44, a first threaded slot 45, a second threaded slot 46 and a fastening bolt 47;

[0048] The outer walls of both sides of the auger shaft 2 are symmetrically provided with mounting shafts 41, and the side outer walls of the mounting shaft 41 are fitted with support shafts 42, which are rotatably mounted with the side inner walls of the support base of the paver body 1;

[0049] The outer side wall of the mounting shaft 41 is provided with a resisting block 43, and the outer side wall of the supporting shaft 42 is provided with a resisting slot 44, and the resisting block 43 and the resisting slot 44 are engaged with each other;

[0050] A first thread groove 45 is formed through the outer wall of the top end of the support shaft 42 at the position where the support shaft 42 contacts the clamping groove 44 , and a second thread groove 46 is formed through the outer wall of the top end of the clamping block 43 at the position corresponding to the first thread groove 45 .

[0051] The first thread groove 45 and the second thread groove 46 are threadedly mounted to the fastening bolt 47 .

[0052] It should be noted that when the auger shaft 2 needs to be installed in the middle position of the two supporting bases before the device is used, it is necessary to first adjust the installation shaft 41 on the side of the auger shaft 2 to a suitable position and then push the interference block 43 on its side into the interference slot 44 at the corresponding position. When the interference block 43 moves to the bottom end of the interference slot 44, the positions of the first thread groove 45 and the second thread groove 46 are in a corresponding fitting state. Then, the fastening bolt 47 is directly used to pass through the first thread groove 45 and screw it to the bottom end of the second thread groove 46 to complete the installation of the auger shaft 2.

[0053] In this embodiment, the opening diameters of the first thread groove 45 and the second thread groove 46 are equal.

[0054] It should be noted that, through the above design, the threaded hole diameters of the fastening bolt 47 and the first thread groove 45 and the second thread groove 46 are consistent, and thus are not likely to loosen after being tightened.

[0055] In this embodiment, the auxiliary movement mechanism 5 includes a telescopic rod 51, a cross bar 52 and a limit handle 53;

[0056] A telescopic rod 51 is installed on the top outer wall of the support base of the paver body 1. There are two groups of telescopic rods 51, and a cross bar 52 is connected between the top outer walls of the two groups of telescopic rods 51 at the output end position. Limit handles 53 are symmetrically provided on the outer walls on both sides of the cross bar 52.

[0057] It should be noted that when manual assistance is required to push the device to move during use, two staff members are required to be located on both sides of the device and simultaneously pull the limit handle 53 to move the device in the opposite direction of its forward movement. The movement of the limit handle 53 will automatically drive the cross bar 52 and the telescopic rod 51 to move, thereby pushing the device forward. When the support height of the telescopic rod 51 needs to be adjusted according to the height of the staff, the support height of the telescopic rod 51 can be directly adjusted. It should be noted that the telescopic rod 51 can be a telescopic rod 51 with a self-locking function on the market. The adjustment principle belongs to the existing conventional technical means and will not be described in detail here.

[0058] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of equivalents of the claims be included in the present invention.
