A mounting method of a deceleration strip installer for a building construction road comprises the following specific steps:
in the initial state, the elastic force of the return spring 59 is larger than that of the compression spring 51;
the first step is as follows: when the deceleration strip needs to be laid, after the moving vehicle 10 moves to the laying position, the two trapezoidal blocks 40 are manually moved, so that the two trapezoidal blocks 40 move towards each other, so that the lifting rod 41 moves downwards, the limiting plate 15 descends and compresses the lifting spring 45, the lower ends of the limiting plate 15, the blocking plate 23 and the guide plate 14 are contacted with the ground, the rightmost electric guide rail 46 works to drive the rightmost supporting plate 11 to move back and forth once, so that one deceleration strip moves downwards to leave the storage cavity 36, so that the deceleration strip enters the external space through the falling cavity 13 and the guide plate 14, when the deceleration strip slides downwards along the guide plate 14, the rotating plate 22 is driven to rotate rightwards, when the deceleration strip is positioned at the right side of the rotating plate 22, the rotating plate 22 rotates and resets, so that the rotating plate 22 is separated from the contact switch 19 and is contacted once, at this time, the driving motor 33 works to drive the winding shaft 32 to rotate, thereby reeling in the rope 29, moving the moving plate 34 to the right and stretching the moving spring 16, so that the lifting plate 35 and the supporting block 18 move to the right, so that the rotating plate 22 moves to the right and drives the speed bump to move to the right, and the driving motor 33 stops moving until the speed bump contacts the blocking plate 23;
the second step is that: two first electromagnets 52 in one ejection cavity 65 work to repel each other, so that the upper end of the upper first electromagnet 52 is located in the through hole 68, at this time, the rotating motor 53 works to drive the transmission shaft 63 to rotate, thereby driving the second bevel gear 62 to rotate, thereby driving the first bevel gear 61 to rotate with the rotating shaft 55, thereby driving the cam 56 to rotate, thereby driving the rotating disc 57 to move downwards, thereby driving the connecting rod 50 to move downwards with the annular supporting block 70 and compress the compression spring 51, when the drill bit 72 descends along with the rotating disc 57 until the drill bit passes through the reserved hole on the deceleration strip to be in contact with the ground, the rotating motor 73 works to drive the drill bit 72 to rotate, thereby starting drilling along with the continuous descending of the drill bit 72, when the drilling is completed, the farthest end of the cam 56 far from the rotating shaft 55 just contacts with the rotating disc 57, at this time, the rotating motor 53 continues to output power, at this time, the compression spring 51, thereby moving the connecting rod 50 and the rotating disk 57 upward, thereby moving the drill bit 72 upward out of the drill hole, and when the annular supporting block 70 is moved to be reset, the rotating motor 53 stops working and the two first electromagnets 52 also stop working, so that the first electromagnet 52 on the upper side is out of the through hole 68;
