[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] See also Figures 1 to 4 As shown, the utility model is a protective device for asphalt concrete road construction site, comprising a base 1 and a movable groove 101 arranged at the edge of one side of the upper surface thereof, the other side of the upper surface of the base 1 is movably connected to the bottom of the adjustment frame 102 through a hinge, and the first fixed block 103 and the second fixed block 104 are respectively installed on both sides of the upper surface of the base 1, and a cleaning component 2 is arranged above the inner and outer sides of the adjustment frame 102, and the angle of the adjustment frame 102 can be adjusted under the action of the hinge, and the first fixed block 103 and the second fixed block 104 are the same in shape, size, etc.;

[0033] The cleaning assembly 2 includes a first motor 201 and a first threaded rod 202 mounted on its output shaft through a coupling, the other end of the first threaded rod 202 passes through a threaded hole at the center of the upper surface of the first moving block 203 and is connected to a bearing at the bottom end of the adjusting frame 102, the first motor 201 drives the first threaded rod 202 to rotate, and the external thread on the outer wall of the first threaded rod 202 is meshed with the internal thread in the wall of the threaded hole on the end face of the first moving block 203, playing a transmission role;

[0034] Warning lights 1021 are installed on both sides of the top of the adjustment frame 102. The upper inner wall of the adjustment frame 102 is movably connected to the connecting rod 1022 through a hinge. A warning plate 1023 is installed inside the inner side of the adjustment frame 102. The warning lights 1021 and the warning plate 1023 are both prior art, so they are not described in detail here. The other end of the connecting rod 1022 is movably connected to the surface of the third moving block 304 through a hinge.

[0035] A telescopic rod 1031 is installed at the center of the outer wall of the first fixed block 103, and a docking block 1032 is installed at the telescopic end of the telescopic rod 1031. The telescopic rod 1031 can be used to telescope and store the docking block 1032.

[0036] A rotating shaft 2041 is installed in a bearing at the center of the outer wall of the first moving block 203, and a cleaning roller 204 is sleeved on the outer side of the outer wall of the rotating shaft 2041. The other end of the rotating shaft 2041 is installed in a bearing on the outer wall of the second moving block 205. The cleaning roller 204 will rotate with the rotating shaft 2041 as the center and clean the surface of the warning plate 1023.

[0037] A guide rod 206 is installed at the inner center of the second moving block 205. The top and bottom ends of the guide rod 206 are respectively fixed to the inner wall of the adjustment frame 102. Under the action of the second moving block 205 and the guide rod 206, the cleaning roller 204 can be assisted to move.

[0038] When the above arrangement is in use, after the warning plate 1023 is used for a long time, the first motor 201 is started, and the output shaft of the first motor 201 rotates to drive the first threaded rod 202 to rotate through the coupling, and the external thread on the outer wall of the first threaded rod 202 is meshed and connected with the internal thread in the wall of the threaded hole on the outer wall of the first moving block 203. Therefore, when the first threaded rod 202 rotates, it will drive the first moving block 203 to move upward or downward.

[0039] Among them Figure 1 , 5 As shown in FIG. 6 , an adjustment assembly 3 is disposed inside the movable groove 101. The adjustment assembly 3 includes a fixed plate 302 and a second motor 301 mounted on the outer wall thereof. The output shaft of the second motor 301 passes through the bearing on the outer wall of the fixed plate 302 and is connected to the second threaded rod 303 through a coupling. The operation of the second motor 301 can drive the second threaded rod 303 to rotate.

[0040] A docking assembly 4 is disposed at the center of the outer wall of the second fixed block 104. The docking assembly 4 includes a docking frame 401 and a seesaw 402 installed above and below the docking frame 401. The edges of the inner wall of the seesaw 402 at both ends are fixedly connected to the outer wall of the rotating rod 403 through connecting blocks. The cross section of the seesaw 402 is L-shaped. The seesaw 402 will rotate around the rotating rod 403 as the center when subjected to force.

[0041] The other end of the second threaded rod 303 passes through the threaded hole on one end face of the third moving block 304 and is connected to the bearing on the inner wall of the moving groove 101. The outer wall of the fixing plate 302 is fixed to the inner wall of the moving groove 101. The external thread on the outer wall of the second threaded rod 303 is meshed with the internal thread in the wall of the threaded hole on the end face of the third moving block 304, which plays a role of transmission.

[0042] A torsion spring 404 is sleeved on the outer side of the outer wall of the rotating rod 403. The two ends of the rotating rod 403 are respectively installed in bearings on the inner walls of the adjacent side plates 405. One end surface of the side plate 405 is fixed on the outer wall of the docking frame 401. The elastic performance of the torsion spring 404 can drive the seesaw 402 to rotate.

[0043] When the above arrangement is in use, the second motor 301 is started, and the output shaft of the second motor 301 rotates, driving the second threaded rod 303 to rotate under the action of the coupling, and the external thread on the outer wall of the second threaded rod 303 is meshed and connected with the internal thread in the wall of the threaded hole on the end face of the third moving block 304, playing a transmission role. Therefore, the position of the third moving block 304 can be adjusted, and the top of the third moving block 304 is connected to the connecting rod 1022 through a hinge, and the other end of the connecting rod 1022 is connected to the inner wall of the adjustment frame 102 through a hinge, and the bottom of the adjustment frame 102 is connected to the surface of the base 1 through a hinge. Therefore, when the third moving block 304 moves, the angle of the adjusting frame 102 can be adjusted under the action of the connecting rod 1022 and the hinge, which is convenient for making corresponding adjustments according to the construction site, with high work efficiency, and saves time and effort. When placing, place the bottoms of multiple protective devices close to each other, and then pull the docking block 1032 outward. The docking block 1032 extends outward under the action of the telescopic rod 1031 and is inserted into the docking frame 401. At this time, the inner end of the seesaw 402 is pressed inward, and the end of the seesaw 402 is forced to rotate with the rotating rod 403 as the center of the circle and squeeze the torsion spring 404. Then, the docking block 1032 is completely inserted into the docking frame 401, and then the force on the seesaw 402 is stopped. At this time, the seesaw 402 will bounce back to the initial position under the elastic performance of the torsion spring 404. Since the shape of the seesaw 402 is L-shaped, it can limit the outer wall of the docking block 1032 to complete the docking. The same is true when disassembling, which is convenient for the staff to quickly dock and separate adjacent protective devices, save time, have high work efficiency, and will not affect the surrounding personnel.

[0044] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
