[0033] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0034] Embodiment 1:

[0035] like Figure 1-3 As shown, a surveying and mapping tool for bridge engineering includes a support base 1, a surveying and mapping instrument 2 installed on the top of the support base 1, and a supporting component 3 and a stabilizing component 4 arranged on the bottom of the support base 1.

[0036] The stabilizing component 4 includes a fixed sleeve rod 5, a movable rod 7, a knob 9 and a base plate 13. The fixed sleeve rod 5 is fixedly connected to the bottom of the support seat 1. The movable rod 7 is slidably matched with the inner wall of the fixed sleeve rod 5, and the inner wall of the fixed sleeve rod 5 is threadedly connected with an adjusting bolt 6 for limiting the movable rod 7. The knob 9 is threadedly connected to the outer wall of the movable rod 7. The bottom of the knob 9 is rotatably connected with a pressure plate. The inner wall of the base plate 13 can only be slidably connected longitudinally with multiple positioning piles 12. The top of the positioning pile 12 is fixed with a limiting plate 10. The bottom of the positioning pile 12 is a pointed end, and the opposite side of the limiting plate 10 and the base plate 13 is buckled with a spring 11.

[0037] The support assembly 3 is used to provide support for the device. When the soil of the surveying area is relatively soft, the adjusting bolt 6 can be rotated to contact the restriction on the movable rod 7, and then the movable rod 7 can be pulled outward until the base plate 13 is in contact with the ground. The adjusting bolt 6 is then rotated to limit and fix the movable rod 7, and then the knob 9 is turned to make the knob 9 drive the pressure plate to move downward along the movable rod 7. When the pressure plate contacts the limit plate 10, the knob 9 is continued to be rotated, and the pressure plate and the limit plate 10 are used to push the positioning pile 12 into the soil. The spring 11 is subjected to force and elastic deformation occurs, thereby increasing the stability of the device.

[0038] The device is provided with a plurality of positioning piles 12, and the knob 9 is rotated to drive the pressure plate to descend, and the pressure plate is used to push the positioning piles 12 into the soil, thereby providing stable support for the device and preventing the device from tipping over and causing damage.

[0039] like Figure 2 , 4 and Figure 5 As shown, the support assembly 3 includes a plurality of support rods 8, which are rotatably connected to the bottom of the support seat 1 via a pin 14, and one end of the pin 14 passes through the support seat 1 and is threadedly connected with a fastening nut 15.

[0040] The bottom of the support rod 8 is connected with a spherical sleeve 17 through a thread, a limiting pin 18 is sleeved inside the spherical sleeve 17, and the outer wall of the support rod 8 above the spherical sleeve 17 is fixedly connected with a support plate 16.

[0041] Loosen the fastening nut 15 outward so that the fastening nut 15 no longer restricts the pin 14, thereby adjusting the rotation angle of the support rod 8. After the adjustment is completed, screw the fastening nut 15 inward so that the support rod 8 can maintain the current angle unchanged; after the spherical sleeve 17 is installed at the bottom of the support rod 8, the angle of the limit pin 18 can be adjusted and the limit pin 18 can be inserted into the soil by stepping on the support plate 16.

[0042] The device is provided with a spherical sleeve 17 and a limiting nail 18. The spherical sleeve 17 is detachably installed at the bottom of the support rod 8. Therefore, when the land to be placed is too bumpy, the limiting nail 18 can be inserted into the land after adjusting the angle. In combination with the positioning pile 12, the stability of the support for the surveying instrument can be enhanced, making it less likely to slide, thereby improving the accuracy of surveying.

[0043] In this embodiment: the device can be used on flat ground, potholes, and soft soil. When used on a flat ground, there is no need to install the spherical sleeve 17. First, loosen the fastening nut 15 so that the support rod 8 can rotate. After the angle of the support rod 8 is adjusted, tighten the fastening nut 15, and use the support rod 8 to support the device on the ground. Then loosen the adjusting bolt 6 so that the movable rod 7 can be pulled out until the bottom plate 13 contacts the ground, and then tighten the adjusting bolt 6 to fix the movable rod 7; when used on a low-lying or soft soil ground, the movable rod 7 is still pulled out and fixed, so that the bottom plate 13 contacts the ground, and the spherical sleeve 17 is installed on the bottom of the support rod 8, and then the angle of the limit pin 18 is rotated as needed, and then the limit pin 18 is aligned with the ground and the foot support plate 16 is stepped on to insert the limit pin 18 into the soil, and then the knob 9 is rotated to drive the pressure plate to descend, and the pressure plate is used to push the limit plate 10 and the spring 11 to descend, so that the spring 11 is inserted into the soil, thereby providing stable support for the device.

[0044] Embodiment 2:

[0045] A surveying and mapping tool for bridge engineering, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 6-8 As shown:

[0046] The support assembly 3 includes a plurality of support rods 8 , a universal ball 19 and a support plate 20 . The universal ball 19 is fixedly connected to the bottom of the support rod 8 , and the support plate 20 is rollingly matched with the outer wall of the universal ball 19 .

[0047] The bottom of the support plate 20 is rotatably connected to a ground nail 21 via a rotating shaft 22 , a pressing block 23 is slidably fitted on the inner wall of one side of the support plate 20 , and a tooth 25 is provided at one end of the rotating shaft 22 .

[0048] The inner wall of the push block 23 is provided with an escape groove, and the inner wall of the escape groove is provided with a tooth groove engaged with the tooth 25, and a spring 24 is buckled on the opposite side of the rotating shaft 22 and the escape groove.

[0049] The bottom of the support plate 20 is provided with a receiving groove for receiving the ground nail 21 .

[0050] In this embodiment: when the push block 23 is pushed inward, the spring 24 is squeezed, and the tooth groove leaves the tooth 25, so that the tooth 25 is located in the avoidance groove. At this time, the rotating shaft 22 is not restricted, and the ground nail 21 can be rotated out of the accommodating groove, and the angle of the ground nail 21 can be adjusted. When the angle is determined, the push block 23 is released, and the push block 23 is pushed outward under the action of the spring 24, and the tooth groove is engaged with the tooth 25 again, thereby limiting the rotating shaft 22 so that it cannot rotate. The ground nail 21 can maintain the current angle unchanged, and then the ground nail 21 is aligned with the ground and the support plate 20 is stepped on to insert the ground nail 21 into the soil; when used on a flat ground, the ground nail 21 can be retracted into the support plate 20, and the universal ball 19 can be used to make the bottom of the support plate 20 fit the ground, providing stability for the device.

[0051] The device is provided with a universal ball 19 and a ground nail 21, and utilizes the characteristics of the universal ball 19 to allow the support plate 20 to rotate arbitrarily, so that after the ground nail 21 is inserted into the soil, the support plate 20 can contact the ground with the maximum area. When the ground nail 21 is not needed, the ground nail 21 can be rotated and retracted into the support plate 20, thereby increasing the flexibility of the device.

[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
