DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] As Figures 1 - 3 shown, an altimeter for the survey and design of public beam bridges according to an embodiment of the present utility model includes an altimeter body 1, a moving component, and a leveling component: A base 2 is fixedly connected to the bottom of the altimeter body 1; The moving component includes two support plates 3 fixedly connected to the bottom of the base 2. The outer wall surface of the support plate 3 is coated with a rough friction coating. A support bottom frame 4 is slidably connected to the outer walls of both support plates 3. Two moving bottom wheels 5 are fixedly connected to the bottom of each support bottom frame 4. An anti-slip washer is sleeved on the outer surface of the moving bottom wheel 5;

[0026] Lower the support bottom frame 4 and the moving bottom wheels 5, and retract the lifting frame 7 and several electric push rods 8. Use the moving bottom wheels 5 to support the moving function of the base 2 and the altimeter body 1 to facilitate the position adjustment and transportation operation of the altimeter.

[0027] As Figure 1 and Figure 2 shown, the leveling component includes a fixing plate 6 fixedly connected to the bottom of the base 2. A lifting frame 7 is slidably connected to the outer wall of the fixing plate 6. Both the fixing plate 6 and the lifting frame 7 are arranged in a concave structure. The outer wall surface of the fixing plate 6 is coated with a rough friction coating. Several electric push rods 8 are fixedly connected to the bottom of the lifting frame 7. A support bottom pad 14 is fixedly connected to the output end of the electric push rod 8;

[0028] Retract the support bottom frame 4 and the moving bottom wheels 5, and lower the lifting frame 7 and several electric push rods 8. Control the output ends of several electric push rods 8 to extend different distances to adjust the height and tilt angle of the base 2, so as to maintain the levelness of the base 2 and the altimeter body 1, thereby facilitating the adjustment of the horizontal position of the altimeter and ensuring the measurement accuracy of the altimeter.

[0029] As Figures 1 - 3 shown, two linkage control components are fixedly connected to the bottom of the base 2. The linkage control component includes a rotating bracket fixedly connected to the bottom of the base 2. A rotating shaft 9 is rotatably connected to the rotating bracket. A rotating motor 13 is fixedly connected to the bottom of the base 2 through a fixed bracket. The output end of the rotating motor 13 is fixedly connected to one end of the rotating shaft 9. Two transmission gears 10 are fixedly connected to the outer wall of the rotating shaft 9. Two first rack plates 11 are fixedly connected to the outer wall of the support bottom frame 4. Two second rack plates 12 are fixedly connected to the outer wall of the lifting frame 7. The racks on the first rack plate 11 and the second rack plate 12 are meshed with the transmission gears 10;

[0030] The rotating motor 13 is driven to rotate the rotating shaft 9, causing the transmission gear 10 to start rotating.

When the base 2 and the altimeter body 1 need to be horizontally adjusted, the support bottom frame 4 and the moving bottom wheels 5 can be retracted, and the lifting frame 7 and several electric push rods 8 can be lowered. The height and tilt angle of the base 2 are adjusted by controlling the output ends of several electric push rods 8 to extend different distances, so as to maintain the levelness of the base 2 and the altimeter body 1, thereby facilitating the adjustment of the horizontal position of the altimeter and ensuring the measurement accuracy of the altimeter.

[0034] 3. During the process of lowering the support bottom frame 4 and the moving bottom wheels 5 and retracting the lifting frame 7 and several electric push rods 8, or retracting the support frame bottom 4 and the moving bottom wheels 5 and lowering the lifting frame 7 and several electric push rods 8, the rotating motor 13 is controlled to start. The rotating motor 13 is driven to rotate the rotating shaft 9, causing the transmission gear 10 to start rotating. Then, the meshing transmission between the transmission gear 10 and the racks on the first rack plate 11 and the second rack plate 12 is used to drive the support frame 1 and the lifting frame 7 to move up and down in the opposite direction, so that the synchronous exchange of the moving function and the leveling function can be realized, and the convenience of using the altimeter can be improved.
