Description

Technical Field

[0001] This utility model relates to the field of building engineering surveying technology, specifically to a level for measuring building engineering costs. Background Technology

[0002] In construction cost estimation, the level is a core instrument used to measure the elevation, distance, and slope of ground points. Its measurement accuracy directly affects the accuracy of the project cost estimate. Leveling the level is a crucial step in ensuring measurement accuracy. It typically requires initial setup using a support structure, followed by fine-tuning of the level's horizontal position using adjustment devices to meet the reliability requirements of engineering surveying data.

[0003] Traditional leveling instruments rely heavily on manual operation for leveling: coarse adjustment is performed by manually extending and retracting the tripod legs, followed by fine adjustment using the mechanical fine-tuning knobs at the bottom of the instrument. This process is cumbersome and inefficient. Especially in complex terrain or when frequently moving the measurement position, the accuracy of fine adjustment after coarse adjustment is easily affected by the operator's experience, making it difficult to quickly achieve a high-precision level. This leads to increased measurement errors and affects the reliability of engineering cost measurement results.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a level instrument for measuring construction engineering costs, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A leveling instrument for measuring construction engineering costs includes a support structure, a connecting structure connected to the support structure, and an instrument structure docked to the connecting structure. The instrument structure achieves automated leveling adjustment through the connecting structure.

[0007] Furthermore, the support structure includes a first rotating support, a mounting plate, a triangular support leg, a threaded knob, a friction rotating ring, and a threaded connecting seat. The mounting plate is fixedly connected to the bottom end of the first rotating support, and the triangular support leg is hinged to the bottom end of the mounting plate.

A threaded knob is threadedly connected to one side of the first rotating support, and a friction rotating ring is rotatably connected to the upper limit of the first rotating support. A threaded connecting seat is fixedly provided on the friction rotating ring.

[0008] Furthermore, the connection structure includes a docking seat, a docking threaded groove, a second rotating support, a mounting ring, an adjusting ball seat, a docking ball cavity, an adjusting servo, an adjusting cam, a pull ring, and a tension spring. The top of the docking seat is fixedly connected to the mounting ring, and the adjusting servo is fixedly connected to the mounting ring. The driving end of the adjusting servo is connected to the adjusting cam. The bottom of the docking seat has a docking threaded groove that matches the threaded connection seat. The docking seat achieves docking with the friction rotating ring through the threaded connection of the threaded groove and the threaded connection seat. The center of the docking seat is fixedly provided with an adjusting ball seat. The top of the docking seat has a second rotating support, and the bottom of the second rotating support has a docking ball cavity. The adjusting ball seat and the docking ball cavity are connected in a damped rotational manner. The docking seat is rotatably connected to the second rotating support through the adjusting ball seat. The mounting ring has a tension spring, and pull rings are connected to both ends of the tension spring.

[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] According to an embodiment of the present invention, a level instrument for measuring the cost of building construction is provided.

[0016] Example 1; like Figure 1-6 As shown, the building construction cost measurement level instrument according to an embodiment of the present utility model includes a support structure 1, a connecting structure 2 connected to the support structure 1, an instrument structure 3 connected to the connecting structure 2, and the instrument structure 3 realizes an automated level adjustment function through the connecting structure 2.

[0017] The support structure 1 includes a first rotating support 101, a mounting plate 102, a triangular support leg 103, a threaded knob 104, a friction rotating ring 105, and a threaded connecting seat 106. The mounting plate 102 is fixedly connected to the bottom end of the first rotating support 101. The triangular support leg 103 is hinged to the bottom end of the mounting plate 102. The triangular support leg 103 is provided with a telescopic support leg. The threaded knob 104 is threadedly connected to one side of the first rotating support 101. The friction rotating ring 105 is rotatably connected to the upper limit of the first rotating support 101. The threaded connecting seat 106 is fixedly provided on the friction rotating ring 105.

[0018] As the basic support component of the overall device, the first rotating support 101 and the triangular support leg 103 are connected by the mounting plate 102. The telescopic support leg of the triangular support leg 103 can adjust the overall support height and stability, realizing the initial erection of the device in different terrains. The friction rotating ring 105 and its threaded connection seat 106 connected to the upper limit of the first rotating support 101 serve as the core interface for docking with the connecting structure 2. The threaded knob 104 can fix the rotation position of the friction rotating ring 105 through the threaded connection, ensuring the relative stability of the support structure 1 and the connecting structure 2 after docking, and providing a solid foundation for subsequent adjustments.

[0019] The connecting structure 2 includes a docking seat 201, a docking threaded groove 202, a second rotating support 203, a mounting ring 204, an adjusting ball seat 205, a docking ball cavity 206, an adjusting servo motor 207, an adjusting cam 208, a pull ring 209, and a tension spring 210. The mounting ring 204 is fixedly connected to the top of the docking seat 201, and the adjusting servo motor 207 is fixedly connected to the mounting ring 204. The driving end of the adjusting servo motor 207 is connected to the adjusting cam 208. The docking seat 201 has a docking threaded groove 202 at its bottom, which engages with the threaded connecting seat 106. The docking seat 201 connects with the threaded connecting seat through the docking threaded groove 202. The threaded connection of 106 enables docking with the friction rotating ring 105. The center of the docking seat 201 is fixedly provided with an adjusting ball seat 205. The top of the docking seat 201 is provided with a second rotating support 203. The bottom end of the second rotating support 203 is provided with a docking ball cavity 206. The adjusting ball seat 205 and the docking ball cavity 206 are connected in a damped rotational manner. The docking seat 201 is rotatably connected to the second rotating support 203 through the adjusting ball seat 205. The mounting ring 204 is provided with a tension spring 210. The two ends of the tension spring 210 are connected with pull rings 209. The pull rings 209 are respectively fixedly installed on the bottom surface of the second rotating support 203 and the top surface of the mounting ring 204.

[0020] As the core component for connecting and adjusting the support structure 1 and the instrument structure 3, the docking seat 201 is threadedly connected to the threaded connection seat 106 of the support structure 1 through the docking thread groove 202 at the bottom of the docking seat 201. The adjusting ball seat 205 at the center of the docking seat 201 is damped and rotatedly connected to the docking ball cavity 206 at the bottom of the second rotating support 203, providing a structural basis for the multi-angle rotation of the second rotating support 203. The eight sets of adjusting servo motors 207 installed on the mounting ring 204 drive the adjusting cam 208 to rotate. Utilizing the elliptical characteristics of the adjusting cam 208, the lifting height of the corresponding point of the second rotating support 203 is changed by different rotation angles. With the help of the pull ring 209 and the tension spring 210, the second rotating support 203 and the adjusting cam 208 are kept in continuous contact, thereby realizing the height adjustment of the eight points of the second rotating support 203, and thus adjusting the horizontal position of the instrument structure 3 to complete the automated horizontal adjustment function.

[0021] The instrument structure 3 includes an adjusting support 301 and a level 302. The level 302 is mounted on the adjusting support 301, and the adjusting support 301 is fixedly connected to the top of the second rotating support 203.

[0022] As the core measuring component of the device, the adjusting support 301 is fixedly connected to the top of the second rotating support 203 of the connecting structure 2. As an adjusting device in the prior art, the adjusting support 301 can make fine adjustments to the horizontal angle and elevation angle of the level 302 installed on it. It works in conjunction with the horizontal adjustment function realized by the connecting structure 2 to ensure that the level 302 is in a precise horizontal state during the measurement process, thereby improving the accuracy and efficiency of construction cost measurement.

[0023] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0024] In summary, with the help of the above-mentioned technical solution of this utility model, the adjustment support 301 of the instrument structure 3 is an adjustment device in the prior art, which can finely adjust the horizontal angle and elevation angle of the level 302. The connecting structure 2 is mainly used for docking the instrument structure 3 with the support structure 1 and can adjust the horizontal position of the instrument structure 3. The horizontal position of the instrument structure 3 is mainly adjusted by the adjustment servo motors 207 distributed on the mounting ring 204 driving the rotation of the adjustment cam 208. There are eight sets of adjustment servo motors 207 evenly distributed on the mounting ring 204. The pull ring 209, together with the tension spring 210, can keep the second rotating support 203 in contact with the cam. Due to the elliptical characteristics of the cam, the servo motor further adjusts the horizontal position of the level 3. During the transmission process of its cam, different rotation angles will cause the cam to produce different lifting heights relative to the corresponding points of the second rotating support 203. The eight sets of cams can adjust the height of the eight points corresponding to the second rotating support 203 within a certain range, thereby changing the relative position of the second rotating support 203 on the docking seat 201, thus realizing fine adjustment of the horizontal position of the level instrument 302. The coarse adjustment of the horizontal position of the level instrument 302 is completed by the triangular support leg 103 of the support structure 1. The triangular support leg 103 is equipped with a telescopic support leg, which can be telescopically adjusted according to the bottom surface conditions, so that the level instrument 302 is in a relatively horizontal position. Then, fine adjustment is performed through the connecting structure 2.

[0025] The second rotating support 203 is connected to the adjusting ball seat 205 at the center of the docking seat 201 via the docking ball cavity 206 at the bottom end, forming a structural foundation that can rotate in all directions. Simultaneously, the tension spring 210 on the mounting ring 204 is connected to the bottom surface of the second rotating support 203 and the top surface of the mounting ring 204 via pull rings 209 at both ends. Under the action of the spring tension, the bottom surface of the second rotating support 203 always maintains close contact with the adjusting cam 208 on the mounting ring 204, providing pre-tight constraint for subsequent adjustment. The adjusting servo motors 207 are provided in eight groups, evenly distributed on the mounting ring 204. Each group of servo motors independently drives the adjustment cam 208 to rotate. Since the adjustment cam 208 has an elliptical structure, the distance from its outer periphery to the rotation center changes with the rotation angle: when the servo motor drives the cam to rotate, the radial height of the contact point between the cam and the bottom surface of the second rotating support 203 changes accordingly. When the long axis of the cam is oriented towards the second rotating support 203... The lifting height is at its maximum when the short axis is facing outwards, and at a medium angle, it corresponds to a medium height. The eight sets of adjusting cams 208 correspond to eight evenly distributed support points on the bottom surface of the second rotating support 203. By controlling the rotation angle of the servo motors at different positions, the lifting height of each support point can be adjusted independently. For example, when the level instrument 302 detects a tilt in a certain direction, the adjusting servo motor 207 corresponding to the tilt direction drives the cam to rotate to the long axis position, increasing the height of that support point; the servo motor in the opposite direction drives the cam to rotate to the short axis position, decreasing the height of the corresponding support point. Combined with the auxiliary fine adjustment of the other support points, the second rotating support 203 rotates around the adjusting ball seat 205 until the overall posture reaches a horizontal state. During this process, the tension spring 210 continuously provides downward force to ensure that the bottom surface of the second rotating support 203 is always in contact with each cam, avoiding gaps or jamming during the adjustment process, and finally realizing the automated horizontal adjustment of the second rotating support 203.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
