A using method of a horizontal measuring device for bridge construction comprises the following steps:
s1: firstly, by shaking a rocker 41, the rocker 41 drives a first worm wheel 39 to rotate through a worm 40, the first worm wheel 39 drives a first nut 3 to move downwards through a first threaded rod 2, and when the first nut 3 moves to the outer side of a box body 1, a support rod 5 is unfolded outwards under the action of a first spring 6 and a limiting plate 7;
s2: when the worm 40 rotates, the first rotating rod 43 is driven to rotate through the second worm wheel 42, the first rotating rod 43 drives the second threaded rod 46 to rotate through the meshing action of the first gear 44 and the second gear 45, and the second threaded rod 46 drives the level to ascend through the action of the first threaded sleeve 47;
s3: then, by pulling the first handle 26 outwards, the first handle 26 drives the movable block 20 to compress the fourth spring 24 through the L-shaped rod 25 to move leftwards, the movable block 20 moves leftwards so that the third spring 18 and the conical plate 17 drive the vertical rod 9 to move upwards, the vertical rod 9 moves upwards to drive the universal wheel 12 to move upwards through the first transverse plate 11, so that the universal wheel 12 is completely retracted into the first box body 10, and the slipping phenomenon during working is prevented;
s4: when the vertical rod 9 ascends, the second connecting rod 32 pushes the sliding block 31 to move downwards under the action of the first connecting rod 27 and the second handle 28, and the movable block 31 moves downwards to enable the bearing plate 35 to be in an unfolded state under the action of the third connecting rod 34 and the fourth connecting rod 38, so that a worker can conveniently record when measuring;
s5: then, by rotating the first rotating disc 54, the first rotating disc 54 drives the second bevel gear 52 to rotate through the third rotating rod 53, the second bevel gear 52 drives the first disc 50 to rotate through the first bevel gear 51 and the second rotating rod 49, and the first disc 50 drives the level body 63 to rotate through the telescopic rod 60 and the second disc 62, so as to adjust the angle of the level body 63;
s6: meanwhile, the second turntable 59 can drive the fourth bevel gear 57 to rotate through the fourth rotating rod 58, the fourth bevel gear 57 drives the second threaded sleeve 61 to move upwards through the third bevel gear 56 and the third threaded rod 55, and the second threaded sleeve 61 drives the level body 63 to adjust up and down through the second disc 60;
s7: then, the size of the second circular opening of the fourth disk 66 can be adjusted through the action of the diamond plates 65, the second rotating shaft 67 and the third rotating shaft 68 by rotating the third disk 64, so that the size of the viewing coil of the eyepiece 77 can be adjusted;
s8: the third disk 64 is rotated while the third gear 70 is driven to rotate by the transmission rod 69, the third gear 70 drives the fourth threaded rod 72 to rotate by the fourth gear 71, the fourth threaded rod 72 drives the sixth connecting rod 81 to move leftwards by the second nut 75, and the sixth connecting rod 81 drives the dust cover 79 to be opened upwards by the fifth connecting rod 80.
The working principle is as follows: firstly, through swinging the rocker 41, the rocker 41 drives the first worm wheel 39 to rotate through the worm 40, the first worm wheel 39 expands the support rod 5 outwards through the action of the first threaded rod 2 and the support mechanism 82, the first rotating rod 43 is driven to rotate through the second worm wheel 42 while the worm 40 rotates, the first rotating rod 43 drives the second threaded rod 46 to rotate through the meshing action of the first gear 44 and the second gear 45, the second threaded rod 46 drives the level gauge to ascend through the action of the first threaded sleeve 47, then the first handle 26 is pulled outwards, the universal wheel 12 is completely retracted into the first box body 10 through the action of the telescopic mechanism 83, the slipping phenomenon is prevented from occurring during working, the bearing plate 35 is in an expanded state through the receiving mechanism 84 through the action of the first connecting rod 27 and the second handle 28 when the vertical rod 9 ascends, so that a worker can conveniently record during measurement, then rotate first carousel 54, can adjust the angle of spirit level body 63 and drive spirit level body 63 and adjust from top to bottom under the effect of adjustment mechanism 85, later can adjust the size of looking the eye coil of eyepiece 77 through slewing mechanism 86 by rotating third carousel 64, drive third gear 70 through transfer line 69 and rotate when rotating third carousel 64, third gear 70 drives fourth threaded rod 72 through fourth gear 71 and rotates, fourth threaded rod 72 drives sixth connecting rod 81 through second nut 75 and moves left, sixth connecting rod 81 drives shield 79 through fifth connecting rod 80 and upwards opens.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
