Description

Technical Field

[0001] This utility model relates to the field of small prism measurement technology, and in particular to an auxiliary support device for a small prism of a total station. Background Technology

[0002] Traditional measurement method a: Directly using the prism-free method. This method is only suitable for situations where high precision is not required. It is clearly unsuitable for measurements requiring high precision. Measurement method b: Directly using the total station's small prism. This method can provide measurements with higher precision than the prism-free method. However, for precision measurements required under special conditions, it is more difficult for surveyors to set up the measuring rod under those conditions. Sometimes, in special circumstances, the line of sight is obstructed, and it is necessary to raise the small prism. The accuracy of the prism's verticality directly affects the measurement results. This is because the higher the small prism is, the greater the impact of its vertical deviation on the measurement results. Sometimes, a combination of factors can even affect the measurement by up to one centimeter, which can lead to significant errors in our measurement results.

[0003] Therefore, a small prism auxiliary support device for total station was developed to solve the above problems. Utility Model Content

[0030] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1 As shown, this utility model discloses an auxiliary support device for a small prism of a total station, comprising:

[0032] Support platform 1, the support platform 1 is provided with mounting through hole 3, the mounting through hole 3 is used for the support leg of the small prism to pass through;

[0033] Support leg 2, one end of which is connected to the bottom of the support platform 1 via a first universal ball joint 23. The bottom of the support platform 1 is connected to three support legs 2. The three support legs 2 can be connected at the bottom of the support platform 1 to form an equilateral triangle. The support leg 2 is a telescopic rod structure.

[0034] The magnetic structure 4 is connected to the other end of the support leg 2 via the second universal ball joint 24.

[0035] like Figure 2 As shown, in some embodiments, one end of the support leg 2 is provided with a first threaded structure, and one end of the support leg 2 is connected to the first universal ball joint 23 through the first threaded structure.

[0036] like Figure 2 As shown, in some embodiments, the other end of the support leg 2 is provided with a second threaded structure, and the other end of the support leg 2 is connected to the second universal ball joint 24 through the second threaded structure.

[0037] Combination Figure 2 and Figure 3As shown, in some embodiments, the support leg 2 includes an inner rod 22, an outer cylinder 21, and a tightening bolt 25. The outer cylinder 21 has a telescopic channel for the inner rod 22, and the inner rod 22 is inserted into the telescopic channel. The upper part of the outer cylinder 21 has a horizontally arranged threaded through hole. One end of the tightening bolt 25 is threadedly connected to the threaded through hole. When the tightening bolt 25 is tightened toward the inside of the outer cylinder 21, one end of the tightening bolt 25 abuts against the outer wall of the inner rod 22 and presses the inner rod 22 against the inner wall of the outer cylinder 21.

[0038] like Figure 1 As shown, in some embodiments, the support platform 1 is a disk structure.

[0039] like Figure 2 As shown, in some embodiments, the magnetic structure 4 is connected to the bottom of the second universal ball joint 24 via a metal base 26. The metal base 26 is provided with a second slot, and the second universal ball joint 24 is hinged in the second ball slot. The magnetic structure 4 is adhered to the bottom surface of the metal base 26.

[0040] like Figure 2 As shown, in some embodiments, the support platform 1 has a first slot at its bottom, and the first universal ball joint 23 is hinged in the first ball slot.

[0041] like Figure 2 As shown, in some embodiments, the other end of the support leg 2 is a pointed structure.

[0042] In use, the support legs of the small prism are inserted into the mounting through hole 3. The size of the mounting through hole 3 is such that the small prism does not wobble. The operator holds the outer guide tube with one hand and the inner guide tube with the other to extend or retract it, allowing the inner layer to rise or fall. Then, tightening the locking screw locks the inner guide tube, thus maintaining stability. Using the built-in bubble level at the top of the small prism, the operator can check and keep the small prism in an upright position for accurate measurement. The specific usage process is as follows:

[0043] Rough setup: Align the tips of the small prism support legs roughly with the points to be measured, then unfold the three support legs 2 of this device, and use the magnetic structure 4 at the bottom of the support legs 2 to hold the steel mold or corresponding steel structure, so that the entire prism system is roughly supported.

[0044] Precise placement: Align the tip of the small prism leg precisely with the point to be measured, and slightly adjust the position of the support leg tip to better ensure the balance and stability of the small prism system. Then adjust the height of each of the three support feet 2 so that the level bubble on the small prism is precisely centered, thus ensuring that the small prism is accurately upright. At this point, tighten the locking devices on the three support legs to complete the entire process of setting up the small prism.

[0045] Considering it's specifically designed for a small prism, and the small prism's height, including the supporting legs, is 100mm, and there are three additional detachable extension rods, each 300mm long, which can be assembled according to site requirements. When using this design, to ensure the fitting is properly secured to the small prism assembly (totaling 400mm in height), and taking into account a certain unfolding angle, the fully folded section should align with the first long segment of the total station's small prism at approximately 450mm. If fully extended, it should be around 600-800mm. Figure 4 As shown, in order to prevent shaking, the mounting through hole 3 of the support platform 1 and its bottom periphery are thickened downward by 10mm to form a stable sleeve 11.

[0046] This invention has the following advantages over the prior art:

[0047] The support leg 2 has a magnetic structure 4, which facilitates attaching the support leg 2 to the steel mold or other steel frame. It is connected via a universal ball joint, and the orientation of the bracket and the magnet base can be adjusted as needed. At the same time, the support leg 2 and the ball joint can be made detachable, so that when a support leg 2 is not on the steel structure, the ball magnet base can be removed, and the support leg 2 can be directly used to stand upright on the ground using its own pointed structure.

[0048] The support leg 2 is retractable, which facilitates operation in special environments;

[0049] The support leg 2 and the support platform 1 are also designed to be connected by a detachable universal ball joint. This allows for adjustments to one of the support legs in the horizontal direction without affecting the leveling of the top connector if it is not possible to ensure that the three support legs can be deployed in 120-degree directions in three special cases. Alternatively, in special cases where it is not possible to install the third support leg 2 and the two support legs 2 can be kept stable, the third support leg 2 can be removed first to avoid affecting the balance and stability formed by the remaining two support legs 2 and the small prism support leg.

[0050] This invention proposes an auxiliary support device for a total station prism. It helps to properly erect the prism in special circumstances, ensuring it remains vertical for as long as possible, thus guaranteeing the accuracy of measurement results. The support rod device frees up the person setting up the measuring rod; after erection, no one needs to constantly hold it. Only the surrounding environment needs to be maintained to ensure the prism is not disturbed by other construction personnel or equipment during measurement. Crucially, it solves the problem of instability in special situations such as on steel formwork trolleys or on steel frames, where a two-legged support plus a prism bracket is often insufficient. Sometimes, even in long tunnels with strong winds, it may not be able to maintain verticality and stability. Therefore, a tripod support is used to directly fix the prism, and the magnetic devices at the tips of the tripod legs can adhere to the formwork wall or steel frame, ensuring the stability of the tripod and thus the stability of the prism.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
