DETAILED DESCRIPTION

[0028] The following will be combined with the attached Figure 1 -Attached Figure 4 The present invention is further illustrated by the following embodiments.

[0029] This embodiment discloses a steel bridge deck paving construction device.

[0030] Reference Figure 1 After the construction is completed, the steel bridge deck includes a steel plate 11, an epoxy resin bonding layer 12 and an epoxy asphalt concrete surface layer 13 from bottom to top. The steel bridge deck paving construction equipment of this embodiment is used to pave the epoxy asphalt concrete surface layer 13 of the steel bridge deck.

[0031] Reference Figure 2 and Figure 3The steel bridge deck paving construction equipment includes a traction device 21 and a mounting plate 22 arranged at the rear end of the traction device 21. The traction device 21 is used to pull the mounting plate 22 forward. In this embodiment, the traction device 21 is a vehicle to achieve automatic traction. In other embodiments, human traction can also be used. An asphalt storage tank 3 is arranged on the top of the mounting plate 22. A feeding port 31 is arranged on the top of the asphalt storage tank 3. Asphalt concrete enters the asphalt storage tank 3 through the feeding port 31. A discharge port 32 is arranged at the bottom of the asphalt storage tank 3. The lower end of the discharge port 32 penetrates the mounting plate 22 downward. The asphalt concrete in the asphalt storage tank 3 falls onto the epoxy resin bonding layer 12 of the steel bridge deck through the discharge port 32. A stirring mechanism is rotatably arranged in the asphalt storage tank 3. The stirring mechanism rotates around the vertical axis. A stirring motor 33 is arranged on the top of the asphalt storage tank 3. The stirring motor 33 is connected to the stirring mechanism to drive the stirring mechanism to perform stirring. By arranging the stirring motor 33 and the stirring mechanism, the condensation of asphalt concrete in the asphalt storage tank 3 can be reduced.

[0032] Reference Figure 2 and Figure 3 A cloth plate 44 is provided at the bottom of the mounting plate 22. The cloth plate 44 is located behind the discharge port 32. The height of the cloth plate 44 is lower than the height of the discharge port 32. The cloth plate 44 is used to pave the asphalt concrete that falls onto the steel bridge deck. The mounting plate 22 is provided with a first height adjustment mechanism. The first height adjustment mechanism is used to adjust the height of the cloth plate 44 to adapt to different paving thicknesses of the asphalt concrete. Specifically, the first height adjustment mechanism includes an adjustment motor 51, a first screw rod 52, a first slide rod 53 and a connecting frame 54. Two first slide rods 53 are provided. The two first slide rods 53 are respectively vertically slidably arranged on the left and right sides of the mounting plate 22. The cloth plate 44 is fixedly connected between the lower ends of the two first slide rods 53 and is movably arranged at the bottom of the mounting plate 22. The adjusting motor 51 is fixedly arranged at the bottom of the mounting plate 22, the connecting frame 54 is fixedly connected to the top of the cloth plate 44, the first screw rod 52 is vertically arranged and the upper end is connected to the adjusting motor 51, and the lower end is connected to the connecting frame 54. When the adjusting motor 51 drives the first screw rod 52 to rotate, the rotation of the cloth plate 44 is restricted, and the connecting frame 54 will drive the cloth plate 44 to rise and fall, thereby realizing the height adjustment of the cloth plate 44. Compared with the manual adjustment method, by setting the first height adjustment mechanism, the effect of facilitating the adjustment of the height of the cloth plate 44 can be achieved.

[0033] Reference Figure 2 and Figure 3, an adjusting plate 41 is provided on the bottom surface of the discharge port 32 to slide back and forth, and the adjusting plate 41 controls the opening size of the discharge port 32 by sliding, and moves closer to or away from the distribution plate 44 by sliding. Further, a fixed rod 42 is fixedly connected to one end of the adjusting plate 41 facing the distribution plate 44, and a movable rod 43 is movably connected between the fixed rod 42 and the distribution plate 44, and the two ends of the movable rod 43 are respectively hinged to the fixed rod 42 and the distribution plate 44, and the end of the movable rod 43 connected to the fixed rod 42 is used as the upper end, and the end of the movable rod 43 connected to the distribution plate 44 is used as the lower end. Through the above arrangement, when the paving thickness increases and the height of the distribution plate 44 needs to be raised, the distribution plate 44 can push the adjusting plate 41 to slide through the movable rod 43 and the fixed rod 42, thereby further opening the opening of the discharge port 32, so that the discharge port 32 of the asphalt storage tank 3 can be enlarged with the increase of the paving thickness, and finally the asphalt concrete surface layer can be filled in time.

[0034] Reference Figure 2 and Figure 3 The bottom surface of the discharge port 32 is an inclined surface, and the highest point and the lowest point of the bottom surface of the discharge port 32 are distributed front and back. Correspondingly, the adjustment plate 41 is set obliquely. The inclined adjustment plate 41 is more conducive to the discharge of the asphalt concrete in the asphalt storage tank 3 through the discharge port 32 than the horizontally set adjustment plate 41. In addition, a right-angled triangle block is fixedly arranged between the front end of the discharge port 32 and the front end of the mounting plate 22. The inclined surface of the right-angled triangle block is coplanar with the bottom surface of the discharge port 32. The adjustment plate 41 slides between the bottom surface of the discharge port 32 and the inclined surface of the right-angled triangle block to improve the sliding stability. Furthermore, a plug hole is opened on the side wall of the discharge port 32, and a baffle is movably inserted into the plug hole. After the baffle is inserted, it is used to stop the discharge of the discharge port 32.

[0035] Reference Figure 2 and Figure 3A pressing wheel 47 is provided at the bottom of the mounting plate 22. The pressing wheel 47 is located behind the material distribution plate 44. The height of the pressing wheel 47 is lower than the height of the material distribution plate 44. The pressing wheel 47 is used to compact the asphalt concrete surface layer after paving. The mounting plate 22 is provided with a second height adjustment mechanism. The second height adjustment mechanism is used to adjust the height of the pressing wheel 47 so that the height of the pressing wheel 47 can be adaptively adjusted according to the height of the material distribution wheel. The second height adjustment mechanism includes an oil cylinder 61, a second sliding rod 62 and a connecting rod 63. Two second sliding rods 62 are provided. The two second sliding rods 62 are respectively vertically slidably arranged on the left and right sides of the mounting plate 22. The pressing wheel 47 is rotatably connected between the lower ends of the two second sliding rods 62 to be movably arranged at the bottom of the mounting plate 22. The connecting rod 63 is connected between the two second slide bars 62, and the oil cylinder 61 is arranged on the top of the mounting plate 22. The oil cylinder 61 is connected to the connecting rod 63. The oil cylinder 61 drives the connecting rod 63 to rise and fall by telescoping, and the connecting rod 63 drives the pressing wheel 47 to rise and fall by using the second slide bar 62, thereby realizing the height adjustment of the pressing wheel 47. In other embodiments, the oil cylinder 61 can be replaced by other lifting control components as long as the lifting control effect can be achieved.

[0036] When the paving thickness of the asphalt concrete surface layer increases, if you still want to maintain a consistent compaction effect, you need to gradually increase the height difference between the pressing wheel 47 and the distributing plate 44 while achieving synchronous lifting of the pressing wheel 47 and the distributing plate 44. Figure 2 and Figure 3 , a positioning plate 45 tilted forward and backward is movably provided at the bottom of the mounting plate 22, the lowest point and the highest point of the positioning plate 45 are distributed forward and backward, the bottom surface of the positioning plate 45 is a curved surface, the positioning plate 45 is horizontally movably provided between the material distribution plate 44 and the pressure wheel 47, and the positioning plate 45 moves forward as the material distribution plate 44 is raised. Further, a positioning wheel 46 is connected between the two second slide bars 62, the positioning wheel 46 is located in front of the pressure wheel 47 and below the positioning plate 45, when the first height adjustment mechanism is used to control the material distribution plate 44 to rise so that the positioning plate 45 moves forward, the second height adjustment mechanism is used to control the pressure wheel 47 to rise until the positioning wheel 46 contacts the positioning plate 45, that is, the height of the pressure wheel 47 is determined by the contact position between the bottom surface of the positioning plate 45 and the positioning wheel 46. Further, under the positioning effect of the positioning plate 45 and the positioning wheel 46, the correlation between the increase in the height of the pressure wheel 47 and the increase in the height of the material distribution plate 44 is as follows: Figure 4 As shown, the ratio of the increase in the height of the pressure wheel 47 to the increase in the height of the distribution plate 44 is less than 1, and the ratio gradually decreases with the increase in height, and ultimately the pressure wheel 47 and the distribution plate 44 are raised synchronously while gradually increasing the height difference between the pressure wheel 47 and the distribution plate 44, so that the asphalt concrete surface layer can always obtain a better compaction effect.

[0037] Reference Figure 2 and Figure 3 In order to achieve the effect that the positioning plate 45 moves forward with the lifting of the cloth plate 44, a linkage assembly is also provided at the bottom of the mounting plate 22, and the linkage assembly includes a gear box 71, a second screw rod 72, a slider 73 and a connecting column 74. The slider 73 is arranged at the bottom of the mounting plate 22 to slide forward and backward, and the slider 73 is connected to the positioning plate 45 through the connecting column 74. The gear box 71 is fixedly arranged at the bottom of the mounting plate 22, and the second screw rod 72 is arranged horizontally and the front end is connected to the adjustment motor 51 through the gear box 71, and the rear end is threadedly connected to the slider 73, and the upper end of the first screw rod 52 is also connected to the adjustment motor 51 through the gear box 71. Finally, when the adjustment motor 51 drives the cloth plate 44 to lift up by using the first screw rod 52, the adjustment motor 51 also drives the positioning plate 45 to move forward by using the second screw rod 72, so that the positioning plate 45 moves forward with the lifting of the cloth plate 44. In this embodiment, a bevel gear set is provided inside the gear box 71, and different bevel gears in the bevel gear set respectively control the rotation of the first screw rod 52 and the second screw rod 72, so that the gear box 71 has an input end and two output ends, and the two bevel gears in the bevel gear set are of the same size to ensure that the strokes controlled by the first screw rod 52 and the second screw rod 72 are consistent.

[0038] Reference Figure 2 and Figure 3 , because in the process of controlling the lifting of the pressure wheel 47, if the human eye is relied on to judge whether the positioning wheel 46 and the positioning plate 45 are in contact, there are still defects of inaccurate positioning and over-reliance on manpower. For this reason, the outer sides of the two second slide bars 62 are hinged with a swing rod 81, and the positioning wheel 46 is rotatably connected between the two swing rods 81. The outer sides of the two second slide bars 62 are also fixedly provided with overlapping blocks 82, and the two overlapping blocks 82 are respectively provided for horizontal overlapping of the two swing rods 81. A force sensor is set on the top of one of the overlapping blocks 82, and the force sensor is connected to the signal of the oil cylinder 61. When the sensing value of the force sensor exceeds the threshold value, the oil cylinder 61 is controlled to stop moving, so that in the process of judging whether the positioning wheel 46 and the positioning plate 45 are in contact, accurate positioning and reduced reliance on manpower are achieved.

[0039] Reference Figure 3 The rear end of the positioning plate 45 is also provided with an avoidance groove for avoiding the telescopic rod of the oil cylinder 61.

[0040] This embodiment also discloses a steel bridge deck paving construction method.

[0043] S2: applying epoxy resin bonding layer 12;

[0045] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto.
