[0025] Example 1

[0026] like Figure 1 to Figure 4 As shown, this embodiment proposes a field survey rod for bridge engineering design, including a main board 1, the bottom surface of the main board 1 is provided with an adjustment mechanism 2, the adjustment mechanism 2 includes three mounting blocks 201 fixedly connected to the bottom surface of the main board 1, and the mounting blocks 201 are hinged with transmission rods 202, the outer surface of each transmission rod 202 is provided with a thread line 203, and the outer surface of the thread line 203 is sleeved with an adjustment cylinder 204, the outer surface of the thread line 203 is threadedly connected with an adjustment ring 205, and the lower end of each adjustment cylinder 204 is fixedly connected with an adjustment ball 206.

[0027] In this embodiment, the setting of the adjustment cylinder 204 can slide at the transmission rod 202, and the adjustment cylinder 204 has damping properties with the transmission rod 202 when sliding, thereby avoiding the risk of the adjustment cylinder 204 slipping. The adjustment cylinder 204 can be limited, blocked and pushed by adjusting the adjustment ring 205, and the setting of the adjustment ball 206 can be suitable for placement on different terrains.

[0028] The outer surface of each adjusting ball 206 is sleeved with a limiting ring 3, and the bottom surface of the limiting ring 3 is provided with anti-slip grooves. By setting the limiting ring 3, the limiting ring 3 can rotate in all directions with the adjusting ball 206, so that it can be suitable for various grounds with large inclinations, and can better facilitate the placement of the entire device, and can reduce the sliding between the device and the ground during placement, thereby greatly improving the stability of the entire device when placed on different terrains.

[0029] The outer surface of each limit ring 3 is fixedly connected to the base 4, and the outer surface of the base 4 is threadedly connected to the bolts 5 in a circular array. By setting the bolts 5, the entire device can be better fixed to the ground when the position is adjusted, thereby facilitating the inspection personnel to carry out survey work.

[0030] A blocking ring 7 is fixedly connected to the outer surface of each adjustment cylinder 204, and the blocking ring 7 is located outside the locking ring 6. By providing the blocking ring 7, it is easier to limit the locking ring 6 and avoid falling off during angle adjustment, thereby greatly improving the safety of the device.

[0031] Example 2

[0032] like Figure 1 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the bottom surface of the mainboard 1 is fixedly connected with an electric push rod 207, and the output end of the electric push rod 207 is fixedly connected with a transmission ring 208, the outer surface of the transmission ring 208 is hinged with a ring-shaped array of transmission plates 209, and each transmission plate 209 is hinged with a push ring 2010 at one end away from the transmission ring 208.

[0033] In this embodiment, the setting of the electric push rod 207 is that by starting the electric push rod 207, the output end of the electric push rod 207 pushes the transmission ring 208 to perform lifting movement, and the transmission ring 208 drives the pushing ring 2010 to move through the transmission plate 209 during the movement, so that the pushing ring 2010 pushes the adjusting cylinder 204 to perform extension movement through the subsequent locking component, and can adjust the extension movement of a single adjusting cylinder 204 according to needs, so that it is suitable for adjustment use in terrains with large height differences.

[0036] The upper surface of the adjustment plate 10 is rotatably connected to a rotating rod 11, and the upper end of the rotating rod 11 is fixedly connected to a triangular prism 12. By setting the rotating rod 11, the triangular prism 12 can be easily rotated, and the triangular prism 12 is used for reflecting the light beam to facilitate length measurement.

[0037] A damping ring 13 is fixedly connected to the upper surface of the adjustment plate 10, and the inner ring of the damping ring 13 is rotatably connected to the outer surface of the rotating rod 11. By providing the damping ring 13, the triangular prism 12 can be more easily rotated, and the damping ring 13 has damping properties, which can avoid the risk of the triangular prism 12 being affected by external factors and rotating when the surveyor adjusts the angle of the triangular prism 12, thereby greatly improving the use stability of the overall device.

[0038] Working principle: When measuring a bridge project on site, the whole device is first placed at a predetermined position. By starting the electric push rod 207, the output end of the electric push rod 207 pushes the adjustment cylinder 204 to extend through the transmission ring 208, the transmission plate 209 and the push ring 2010, so that the whole device is placed. By rotating the adjustment ring 205, the adjustment ring 205 performs an adjustment movement at the transmission rod 202, so that the adjustment ring 205 pushes the adjustment cylinder 204 to adjust the length, so that it is suitable for adjustment in different terrains, and a single adjustment cylinder 20 4 can be adjusted, which greatly improves the application range of the device, and through the cooperation between the adjusting ball 206 and the limiting ring 3, the device can be fixed on the inclined ground through the bolt 5 and the base 4 for stable placement, thereby further improving the application range and convenience of use of the device, avoiding the situation where it is inconvenient to install or unstable to place on the ground with a large inclination angle, and through the cooperation between the pushing ring 2010 and the locking ring 6, the control of the single adjusting cylinder 204 can be released, so that the single adjusting cylinder 204 can be extended and adjusted for use, thereby greatly improving the convenience of the device.
