Description

Technical Field

[0001] The utility model relates to the technical field of surveying devices, in particular to a surveying device for cost engineering. Background Technique

[0002] In the field of engineering construction, cost engineering plays a crucial role. With the continuous development of social economy and the increasing number of construction projects, the accurate determination and effective control of project cost have become increasingly critical. With the development of information technology and the update of management concepts, modern cost engineering has gradually introduced advanced calculation methods, software tools, and the concept of whole-process management to achieve precise control and optimization of project cost, and improve the economic and social benefits of engineering construction.

[0003] Chinese Patent with the publication number CN221237508U discloses a on-site surveying device for building project cost. By rotating the worm through the handle, the position of the second connecting column is adjusted, so as to adjust the relative height between the surveying instrument and the support block, playing a role in finely adjusting the surveying instrument, making the surveyed data more accurate, and being suitable for the usage habits of workers, facilitating the workers to adjust the surveying device for surveying. A fixing mechanism is added to the surveying device. The umbrella handle is inserted into the limiting groove, and then the umbrella is clamped and limited through the cooperation of the limiting column and the fixing block, so that the workers do not need to hold an umbrella by hand for surveying in rainy weather, and at the same time, it is beneficial to prevent the surveying device from getting water, and the practicability is good.

[0004] However, in the actual application of the on-site surveying device for building project cost in the above scheme, the usage site is not always a flat ground. When encountering an inclined ground, it cannot flexibly adapt to the inclination angle of the ground, resulting in the bottom of the device not being able to fit well with the ground, being unstable, and further affecting the accuracy of the measurement data.

[0005] Therefore, it is necessary to invent a surveying device for cost engineering. Content of the Utility Model

[0006] The purpose of the utility model is to provide a surveying device for cost engineering to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A surveying device for cost engineering, including a cross plate, a protective shell is fixedly arranged on the top of the cross plate, a support plate is slidably arranged in the protective shell, a measurement main body is fixedly arranged on the top of the support plate, a plurality of C-shaped plates are fixedly arranged on the bottom of the cross plate, a support leg is rotatably arranged between the two side walls of the C-shaped plate, a ball hinge is fixedly arranged at the bottom end of the support leg, a base is arranged at the bottom end of the ball hinge, a fastening bolt is threadedly inserted on one side of the ball hinge, and a groove is opened at the bottom of the base, and a tapered column is rotatably arranged in the groove.

A base 22 is arranged at the bottom end of the ball hinge 21. A fastening bolt 23 is threadedly inserted into one side of the ball hinge 21. A groove 24 is opened at the bottom of the base 22. A tapered column 25 is rotatably arranged in the groove 24.

[0027] Further, a short shaft 26 is rotatably arranged between the two side walls of the groove 24. The short shaft 26 is fixedly connected with the tapered column 25, which facilitates the rotation of the tapered column 25.

[0028] Further, one end of the short shaft 26 penetrates through the groove 24 and the base 22 and a second disc 261 is fixedly arranged at its end. A second fixing block 27 is fixedly arranged on one side of the base 22. A second spring 271 is fixedly arranged on one side of the second fixing block 27. A second T-shaped block 28 is fixedly arranged at the other end of the second spring 271. A second inserting post 29 is fixedly arranged on the other side of the second T-shaped block 28. The second inserting post 29 is movably inserted into the second disc 261, which facilitates the fixation of the second disc 261.

[0029] Further, a plurality of second circular grooves 262 are opened on the outer side of the second disc 261. The second inserting post 29 is movably inserted into the second circular grooves 262.

[0030] Further, symmetrically distributed sliding grooves 131 are opened on the inner side wall of the protective shell 13. Symmetrically distributed sliding rods 121 are fixedly arranged on the outer side of the support plate 12. The sliding rods 121 are slidably installed in the sliding grooves 131, which facilitates the sliding of the sliding rods 121.

[0031] Further, symmetrically distributed blocks 31 are fixedly arranged on the outer side of the protective shell 13. A screw 32 is threadedly inserted into one side of the block 31. Symmetrically distributed inserting slots are opened on one side of the sliding rod 121. The screw 32 movably penetrates through the inserting slots, which facilitates the fixation of the sliding rod 121.

[0032] Further, a rotating shaft 15 is rotatably arranged between the two side walls of the C-shaped plate 14. The rotating shaft 15 is fixedly connected with the support leg 16, which facilitates the rotation of the support leg 16.

[0033] Further, one end of the rotating shaft 15 penetrates through the C-shaped plate 14 and a first disc 151 is fixedly arranged at its end. A first fixing block 17 is fixedly arranged on one side of the C-shaped plate 14. A first spring 171 is fixedly arranged at the bottom of the first fixing block 17.

[0035] Working principle: When this solution is in use, during the survey process, the rotation angle of the base 22 can be adjusted according to the inclination degree of the ground. When the device is on an inclined ground, the fastening bolt 23 can be loosened, then the base 22 is rotated and the base 22 is made parallel to the ground, and then the fastening bolt 23 is tightened again to prevent the ball hinge 21 from rotating, which is convenient for the base 22 to fit the ground more closely, thereby realizing the fixation of the base 22 and further stably fixing the device;

[0036] When it is used on a relatively soft soil surface, by rotating the conical column 25 to be perpendicular to the ground and inserting the conical column 25 into the ground, the contact area and friction with the ground are increased, preventing shaking or tilting during use and improving the stability of the device;

[0037] When the device needs to be stored, the first inserting post 173 is removed from the first disc 151, thereby compressing the first spring 171. Then, the three support legs 16 are stored. Finally, the first inserting post 173 is inserted into the first disc 151 again to fix the support legs 16. Then, the screw 32 can be removed from the sliding rod 121, and the support plate 12 and the measuring body 11 are stored in the protective shell 13. Then, the screw 32 is inserted into the sliding rod 121 again to fix the support plate 12 and the measuring body 11, thereby protecting the measuring body 11 when the device is stored.
