Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying and setting out technology, specifically an engineering surveying and setting out device. Background Technology

[0002] Engineering surveying and setting out is a core step in building construction, determining the location, axis, elevation, and geometry of buildings, directly impacting construction quality. Commonly used tools include traditional tools and modern surveying instruments. Modern surveying instruments mainly include total stations, laser levels, RTK-GPS surveying systems, 3D laser scanners, electronic theodolites, and laser rangefinders. Because these instruments are used with tripods and in complex environments, almost all of these instruments require being kept level. This necessitates tripod leveling. Although existing tripod technologies allow for quick adjustments, the accuracy of these adjustments is difficult to control. Utility Model Content

[0003] To address the problem of difficulty in controlling the leveling accuracy of measuring equipment used in a horizontal state, this utility model provides an engineering surveying and setting-out device.

[0004] This utility model is achieved through the following technical solution:

[0005] An engineering surveying and setting-out device includes a surveying and setting-out instrument body and a tripod assembly supporting the surveying and setting-out instrument body. The tripod assembly includes a mounting plate, a support sleeve, and an inner connecting rod. The surveying and setting-out instrument body and a level are mounted on the mounting plate. The top of the support sleeve is hinged to the mounting plate. The inner connecting rod is inserted into the support sleeve. An adjusting toothed plate is provided on the inner connecting rod.

[0006] The support tube sleeve is provided with an adjusting gear that can mesh with the adjusting tooth plate. One side of the adjusting gear is provided with a limiting tooth plate installed in the support tube sleeve and capable of meshing with the adjusting gear. The outside of the support tube sleeve is provided with a rotating rod that passes through the support tube sleeve. The rotating rod drives the adjusting gear to move along the tooth line direction of the adjusting tooth plate and realizes contact or separation with the limiting tooth plate.

[0007] The operating adjustment gear controls the extension of the inner connecting rod beyond the length of the support sleeve, and the adjustment state can be stabilized through contact with the limit tooth plate; the cooperation between the gear and the tooth plate enables controllable precision; during operation, a level instrument is used for verification.

[0008] A further improvement of this utility model is that the aforementioned support sleeve has an adjustment window opposite to the limiting toothed plate, and the adjustment window is covered by a cover plate installed on the support sleeve, with the rotating rod provided on the cover plate. The limiting toothed plate is installed inside the support sleeve through the reserved adjustment window.

[0009] A further improvement of this invention is that the adjustment window is located above the middle of the support sleeve. The adjustment window is positioned high up, allowing the operator to easily observe the horizontal level while operating the adjustment gear.

[0010] A further improvement of this invention is that a knob is provided on the outside of the aforementioned support sleeve to mount the rotating rod. The rotating rod is driven by the knob, making operation convenient.

[0011] A further improvement of this invention is that the inner wall of the aforementioned support sleeve is provided with a guide strip arranged along its length, and the inner connecting rod is provided with a guide groove adapted to the guide strip. The cooperation between the guide strip and the guide groove ensures the stability of the sliding operation of the inner connecting rod on the support sleeve.

[0012] A further improvement of this invention is that the cross-section of the guide strip is dovetail-shaped, forming a two-way constraint on the inner connecting rod and preventing lateral swaying.

[0013] A further improvement of this utility model is that an adjustment groove is provided on the upper part of the inner connecting rod, and an adjustment toothed plate is provided on one inner wall of the adjustment groove. The adjustment groove allows the inner connecting rod to avoid the limiting toothed plate when moving within the support sleeve, while also increasing the guiding contact surface between the inner connecting rod and the support sleeve.

[0014] A further improvement of this invention is that the bottom of the inner connecting rod is provided with a foot, and the top surface of the foot is universally connected to a connecting rod installed at the bottom of the inner connecting rod. This universal connection between the connecting rod and the foot helps improve the adaptability of the tripod assembly to uneven road surfaces.

[0015] A further improvement of this invention is that the bottom surface of the aforementioned foot is evenly distributed with at least three conical spikes. The use of spikes helps to increase the stability of the tripod assembly in contact with the ground.

[0016] A further improvement of this utility model is that the outer periphery of the mounting plate is evenly distributed with ear plates one that match the number of support tube sleeves, and ear plates two that are hinged to the ear plates one and installed at the top of the support tube sleeves.

[0017] As can be seen from the above technical solution, the beneficial effects of this utility model are: the operation of the adjusting gear controls the extension of the inner connecting rod out of the support sleeve, and the stability of the adjustment state can be achieved through contact with the limiting tooth plate; the cooperation between the gear and the tooth plate achieves controllable precision; and the operation is checked in conjunction with the observation of the level.
