Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, specifically to an engineering surveying device for construction. Background Technology

[0002] Construction engineering surveying devices are a general term for a class of instruments and equipment used throughout the construction process to measure, lay out, and monitor geometric quantities such as ground points, elevations, distances, angles, shapes, and positions. Their core purpose is to accurately "place" the buildings on the design drawings onto the actual site and ensure the accuracy and safety of the construction process. With the continuous development of construction engineering, various surveying devices have emerged, such as a construction engineering surveying device.

[0003] A search revealed a surveying device for architectural engineering surveying, patent number CN202420539885.1. This device includes a tripod and a surveying module. The tripod consists of a support platform and three telescopic legs. The surveying module has a rotating base at its bottom, and a main shaft at its bottom. A first ball head is fixed on the main shaft, and the support platform has a first ball seat. A second and third ball head are movably fitted onto the main shaft. A first and second adjusting frame are horizontally slidably mounted on the support platform. The first adjusting frame has a first groove, and the second adjusting frame has a second groove. The support platform also has a first threaded push rod and a second threaded push rod. This invention allows for simultaneous rotation of the two threaded push rods by both hands. The device uses two screw rods that rotate in both directions to control the spindle's rotation at any angle and direction within a certain range, thus achieving horizontal leveling of the surveying module. This results in relatively high leveling efficiency. However, while the device can control the spindle's rotation at any angle and direction within a certain range using the two screw rods, the elevation angle can only be changed by adjusting the two screws with both hands. The elevation angle depends on the vertical distance between the first and second adjustment frames, and the adjustment range is relatively small, not exceeding 180 degrees. Furthermore, the screws are small and located on the side, making finger adjustment cumbersome, and the device uses many mechanical parts. Therefore, a construction engineering surveying device is proposed that can adjust the elevation angle of the surveying instrument 360 degrees and can be changed with one hand, offering simple and convenient operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an engineering surveying device for construction, which has the advantages of being able to adjust the elevation angle of the surveying instrument by 360 degrees and changing the elevation angle with one hand, and being simple and convenient to operate. It solves the problems of the Chinese utility model patent with patent number CN202420539885.1, which requires two hands to adjust the elevation angle by adjusting two screws, the elevation angle depends on the vertical distance between the first and second adjustment frames, the elevation angle adjustment range is small and does not exceed 180 degrees, the screws are small and are all on the side, and the adjustment by fingers is relatively troublesome.

[0005] To achieve the above-mentioned goal of being able to adjust the elevation angle of the surveying instrument by 360 degrees and change the elevation angle with one hand, and to make the operation simple and convenient, this utility model provides the following technical solution: a construction engineering surveying device, including a tripod, a fixed plate fixedly installed on the top of the tripod, a movable plate provided on the top of the fixed plate, and an adjustment mechanism provided on the top of the movable plate; The adjustment mechanism includes a mounting box one, a rotating column, a worm gear, a worm, a frosted column, a bearing one, a movable rod, a rubber ring, a mounting box two, a bearing two, and a bearing three. The top of the movable plate is fitted with mounting box one, and the rotating column is housed inside mounting box one. A worm gear is fixedly connected to the outside of the rotating column, and a worm meshes with the outside of the worm gear. A frosted column is fixedly mounted on the top of the worm. The inside of the fixed plate is fitted with bearing one, and the top of bearing one is fitted with a movable rod. A rubber ring is provided on the opposite surface of the fixed plate and the movable plate. The top of the movable plate is fitted with mounting box two, and the inside of mounting box two is fitted with bearing three.

[0006] Furthermore, four connecting posts are welded to the top of the movable plate. The four connecting posts are divided into two groups, with two posts in each group. Mounting box one and mounting box two are welded to the movable plate through the two groups of connecting posts respectively.

[0007] Furthermore, a rotating hole is provided on the top of the mounting box, which is adapted to the worm gear. A movable hole is provided on the right side of the mounting box, which is adapted to the rotating column. A surveying instrument is fixedly installed on the outside of the rotating column.

[0008] Furthermore, the bottom of the worm gear is fixedly connected to the interior of bearing three, and the worm gear is movably connected to mounting box one through bearing three.

[0009] Furthermore, the movable rod is fixedly connected to the inner ring of the bearing, the movable rod is movably connected to the fixed disk through the bearing, and the top of the movable rod is welded to the movable disk.

[0010] Furthermore, the right side of the rotating column is fixedly connected to the inner ring of the bearing two, and the rotating column is movably connected to the mounting box two through the rotating column.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: This engineering surveying device for construction uses an adjustment mechanism. When the elevation angle needs to be adjusted, the user grips the frosted column with one hand and rotates it clockwise. This engages the worm gear with the worm wheel, thereby driving the surveying equipment on the rotating column to adjust the elevation angle. Through continuous rotation, the surveying equipment can be rotated to a suitable position at a large angle without restriction on elevation angle rotation. The horizontal angle can be adjusted by directly rotating the adjusting bar on the movable disc, and vice versa. This adjustment mechanism can adjust the elevation angle of the surveying instrument 360 degrees and can be changed with one hand, making it simple and convenient to operate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 An engineering surveying device for construction in this embodiment includes a tripod 1, a fixed plate 2 fixedly installed on the top of the tripod 1, a movable plate 3 provided on the top of the fixed plate 2, and an adjustment mechanism 4 provided on the top of the movable plate 3. The adjusting mechanism 4 includes mounting box 1 401, rotating column 402, worm gear 403, worm 404, frosted column 405, bearing 1 406, movable rod 407, rubber ring 408, mounting box 2 409, bearing 2 4010, and bearing 3 4011. Mounting box 1 401 is installed on the top of the movable plate 3. Rotating column 402 is installed inside mounting box 1 401. Worm gear 403 is fixedly connected to the outside of rotating column 402. Worm 404 is meshed with the outside of worm gear 403. Frosted column 405 is fixedly installed on the top of worm 404. Bearing 1 406 is installed inside the fixed plate 2. Movable rod 407 is installed on the top of bearing 1 406. Rubber ring 408 is installed on the opposite side of fixed plate 2 and movable plate 3. Mounting box 2 409 is installed on the top of the movable plate 3. Bearing 2 4010 is installed inside mounting box 2 409. Bearing 3 4011 is installed inside mounting box 1 401.

[0016] In the implementation of the case, four connecting columns are welded to the top of the movable plate 3. The four connecting columns are divided into two groups, with two columns in each group. Mounting box 1 401 and mounting box 2 409 are welded to the movable plate 3 through the two groups of connecting columns. The "welding" and "connecting columns" ensure the firmness and stability of the connection between the mounting box and the movable plate, thereby improving the structural strength and reliability of the entire adjustment mechanism 4 and preventing the measurement accuracy from being affected by loose connections during adjustment or use.

[0017] In the implementation of the case, the top of the mounting box 401 is provided with a rotating hole that is adapted to the worm gear 404. The right side of the mounting box 401 is provided with a movable hole that is adapted to the rotating column 402. A surveying instrument is fixedly installed on the outside of the rotating column 402, which ensures that the worm gear 404 and the rotating column 402 can pass smoothly through the mounting box 401 and rotate, reducing unnecessary friction and interference.

[0018] In the implementation of the case, the bottom of the worm 404 is fixedly connected to the bearing 4011, and the worm 404 is movably connected to the mounting box 401 through the bearing 4011. Using the bearing 4011 to support the worm 404 can greatly reduce the friction and shaking when the worm 404 rotates, ensuring that the rotation and elevation angle adjustment process is smooth, effortless and precise. This enhances the comfort of the adjustment feel and the accuracy of the adjustment result.

[0019] In the implementation of the case, the movable rod 407 is fixedly connected to the inner ring of the bearing 406, and the movable rod 407 is movably connected to the fixed disk 2 through the bearing 406. The top of the movable rod 407 is welded to the movable disk 3. The movable connection between the movable rod 407 and the fixed disk 2 is realized through the bearing 406, so that the movable disk 3 can rotate flexibly horizontally relative to the fixed disk 2.

[0020] In the implementation of the case, the right side of the rotating column 402 is fixedly connected to the inner ring of the bearing 4010. The rotating column 402 is movably connected to the mounting box 409. The bearing 4010 provides stable support for the other end of the rotating column 402. Together with the structure inside the mounting box 401, they ensure that the rotating column 402 can only rotate around its axis and will not move radially. This further ensures the stability and pointing accuracy of the surveying instrument during the elevation angle adjustment process and avoids measurement errors caused by shaft wobble.

[0021] When implementing this procedure, please follow these steps: 1) When it is necessary to adjust the elevation angle, hold the frosted column 405 firmly with one hand; 2) Then rotate clockwise so that the worm 404 meshes with the worm wheel 403; 3) Then, drive the surveying equipment on the rotating column 402 to adjust the elevation angle; 4) Finally, by continuously rotating, the surveying equipment can be rotated to a suitable position at a large angle. The elevation angle rotation is unrestricted, and the horizontal angle can be adjusted by directly rotating the adjusting bar on the movable disk 3.

[0022] In summary, this engineering surveying device for construction, through the setting of the adjustment mechanism 4, allows for adjustment of the elevation angle by holding the frosted column 405 with one hand and rotating it clockwise. This causes the worm gear 404 to mesh with the worm wheel 403, thereby driving the surveying equipment on the rotating column 402 to adjust the elevation angle. Through continuous rotation, the surveying equipment can be rotated to a suitable position at a large angle, with no restriction on the elevation angle rotation. Furthermore, the horizontal angle can be adjusted by directly rotating the adjustment bar on the movable disk 3. This adjustment mechanism 4 can adjust the elevation angle of the surveying instrument 360 degrees and can change the elevation angle with one hand, making the operation simple and convenient.
