DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 As shown, an auxiliary surveying tool for construction engineering cost includes a mounting platform 1, a circular placement opening is provided on the top of the mounting platform 1, a fixed structure 2 is movably installed at the axis of the bottom of the mounting platform 1, three extension structures 3 are rotatably installed at the edge of the bottom of the mounting platform 1 in a circular distribution, a placement structure 4 is movably installed at the bottom of the three extension structures 3, a counterweight structure 5 is movably installed at the middle of one side of the three extension structures 3 close to the fixed structure 2, and a surveying instrument 6 is arranged on the top of the mounting platform 1, and the bottom of the surveying instrument 6 is threadedly connected with the top of the fixed structure 2. The mounting platform 1 can provide an installation position for some parts of the device, the placement opening can provide a placement position for the surveying instrument 6, the fixed structure 2 can fix the surveying instrument 6, the extension structure 3 can provide support of different heights for surveying by its own rotation and extension, the staff can switch the device to the sliding placement mode by adjusting the placement structure 4, so as to facilitate the sliding displacement of the device, the staff can adjust the counterweight structure 5 according to the surveying needs, so as to improve the placement stability of the device, and at the same time avoid the device being too heavy and causing difficulty in carrying, and the staff can survey the site through the surveying instrument 6.

[0028] like Figure 2 and Figure 3 As shown, the fixing structure 2 includes a limit clamp 21, and three mounting grooves 11 are installed in a circular arrangement on the inner side of the bottom of the mounting platform 1. The right part of the limit clamp 21 is rotatably installed on the inner side of the mounting groove 11 located on the right side, and the left part of the limit clamp 21 extends to the bottom left position of the placement port. A threaded handle 22 is slidably installed on the inner side of the limit clamp 21, and the top of the threaded handle 22 is threadedly connected with the bottom of the surveying instrument 6. The mounting groove 11 can provide a mounting position for some parts of the device. The limit clamp 21 can movably install the threaded handle 22 on the inner side of the placement port, and when the staff holds the threaded handle 22 to move, the threaded handle 22 is limited through the inner opening, so that the threaded handle 22 can only be horizontally displaced on the inner side of the placement port. When the staff places the surveying instrument 6 on the placement port, the staff can adjust the position of the threaded handle 22 and rotate it so that the top of the threaded handle is turned into the threaded port at the bottom of the surveying instrument 6 to complete the fixation.

[0029] like Figure 4 and Figure 5As shown, the extension structure 3 includes three mounting shells 31, and the left and right sides of the tops of the three mounting shells 31 are rotatably connected to the adjacent sides of each two mounting slots 11, and the left and right sides of the inner cavities of the three mounting shells 31 are fixedly installed with mounting columns 32, and the adjacent sides of the two mounting columns 32 are slidably installed with an extension slot plate 33, and the top and bottom of the outer wall of the extension slot plate 33 are fixedly installed with a first locking component 34 and a second locking component 35, respectively, and the middle and bottom of the two mounting columns 32 are respectively located at the inner left and right positions of the first locking component 34 and the second locking component 35, and a mounting opening is opened at the bottom of the extension slot plate 33. The mounting shell 31 and the mounting opening can provide mounting positions for some parts of the device. When the device needs to be extended and supported, the staff can open the first locking component 34 and the second locking component 35, and hold the mounting platform 1 and pull it upward to drive the mounting column 32 to move upward. The extension slot plate 33 remains stationary due to its own gravity to allow the structure to be extended. After the extension is completed, the first locking component 34 and the second locking component 35 can be closed to lock the extension slot plate 33 and the two mounting columns 32. Then, as needed, the top position of the mounting shell 31 can be used as a rotation node to rotate outward to expand the extension structure 3, so that the entire device is in a triangular column shape to complete the support, and after the overall support, fine-tuning can be performed by opening and closing the first locking component 34 and the second locking component 35.

[0030] like Figure 6 and Figure 7 As shown, the placement structure 4 includes a fixing bolt 41, which passes through the left and right sides of the bottom of the extension slot plate 33 and is rotatably installed on the bottom of the extension slot plate 33. A mounting block 42 is fixedly installed in the middle of the fixing bolt 41, and the mounting block 42 is located on the inner side of the bottom of the extension slot plate 33. A buffer shell 43 is fixedly installed on the top of the mounting block 42, and a spring is fixedly installed on the bottom of the inner cavity of the buffer shell 43. A universal wheel 44 is fixedly installed on the top of the spring, and the bottom of the universal wheel 44 is located on the inner side of the top of the buffer shell 43. A placement foot 45 is fixedly installed on the bottom of the mounting block 42. The three placement feet 45 can fix and support the device when it is unfolded, and the mounting block 42 can provide an installation position for some parts. When the device needs to be moved quickly, the staff can turn the nut on the right side of the fixing bolt 41 to unlock the fixing bolt 41, and then the mounting block 42 and the parts thereon can be rotated. After adjusting the universal wheel 44 to a suitable position, the staff can re-lock the mounting block 42 and the parts thereon by turning the nut. The universal wheel 44 can buffer the displacement in the vertical direction of the inner side of the buffer shell 43, and the spring can buffer the universal wheel 44 during the pushing process, thereby facilitating the device to pass through rugged roads, thereby improving the portability and practicality of the device.

[0031] like Figure 6As shown, a pedal is fixedly installed on the top of the placement foot 45 away from the mounting block 42, and a plurality of strip friction grooves are provided on the top of the pedal. When the device is used on a muddy placement surface, the staff can drive the placement foot 45 deep into the mud by stepping on the pedal, thereby improving the placement stability of the device, and the strip friction groove can increase the contact friction between the user's foot and the pedal, making it easier to step on it stably.

[0032] like Figure 1 and Figure 8 As shown, the counterweight structure 5 includes three mounting rods 52, one end of the three mounting rods 52 away from the mounting platform 1 is rotatably connected to the middle part of one side of the three extension slot plates 33 close to the mounting platform 1, and one end of the three mounting rods 52 close to the mounting platform 1 is rotatably installed with a connecting block 51, a threaded column 53 is hung at the bottom of the connecting block 51, and a disassembly disk 54 is threadedly installed at the bottom of the threaded column 53, and a plurality of counterweight blocks 55 are clamped on the outer wall of the threaded column 53, and the bottom of the counterweight block 55 located at the bottom is in contact with the top of the disassembly disk 54. The three mounting rods 52 and the connecting block 51 can provide installation positions for some components and guide the structural components to move to the bottom position of the device through their own gravity during the extension process, thereby improving the placement stability of the device. When the staff needs to adjust the number of counterweight blocks 55, they can hold the disassembly disk 54 and rotate it until the top surface of the top counterweight block 55 no longer generates pressure with the remaining components to complete the unlocking. The staff can quickly remove and place the counterweight block 55 from the threaded column 53 through the notch on the counterweight block 55. After the adjustment is completed, rotate the disassembly disk 54 in the opposite direction to move the disassembly disk 54 upward until the top counterweight block 55 is locked.

[0033] The working principle of the utility model is as follows: before extending the device, the staff can open the first locking component 34 and the second locking component 35, and hold the mounting platform 1 and pull it upward to drive the mounting column 32 to move upward. The extension slot plate 33 remains stationary due to its own gravity to allow the structure to extend. After the extension is completed, the first locking component 34 and the second locking component 35 can be closed to lock the extension slot plate 33, and then the extension structure 3 can be rotated outward as needed to make the device as a whole in a triangular column shape to complete the support, and after the overall support, the first locking component 34 and the second locking component 35 can be opened and closed for fine adjustment. After the unfolding and placement is completed, the staff can adjust the counterweight structure 5 according to the needs of surveying and mapping, thereby improving the placement stability of the device and avoiding the difficulty of carrying due to the excessive weight of the device. After the counterweight adjustment is completed, the staff can place the surveying instrument 6 on the placement port, and the staff can adjust the position of the threaded handle 22 and rotate it so that the top of the handle is turned into the threaded port at the bottom of the surveying instrument 6 to complete the fixation, and then the surveying and mapping operation can be carried out.
