Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a building construction surveying and mapping device. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. The place where the construction work is done is called "construction site" or "construction site", also called construction site.

[0003] The commonly used surveying tools in the construction process include: triangular ruler, ruler, vernier card, surveying instrument and other common measuring tools. The existing surveying instrument needs to be folded and carried after the bracket is moved when it is used, which is troublesome, increases the time cost and is inconvenient to use. Therefore, we propose a construction surveying device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a construction surveying and mapping device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A construction surveying and mapping device comprises a base plate, the outer surface of the base plate is fixedly connected with fixing grooves arranged at equal distances, the interiors of the three fixing grooves are all hinged with support rods through pins, the interior of each of the support rods is sleeved with a first connecting rod, the bottom end of each of the first connecting rods is fixedly connected with a base, the bottom surface of each of the bases is fixedly connected with a universal wheel, the upper surface of the base plate is fixedly connected with a fixed shaft, the outer surface of the fixed shaft is fixedly connected with a first bearing, the outer surface of the first bearing is fixedly connected with a turntable, the upper surface of the turntable is fixedly connected with an outer shell, a second connecting rod is provided inside the outer shell, the top end of the second connecting rod passes through the outer shell and is fixedly connected with a surveying instrument.

[0007] In a further embodiment, a rotating rod is fixedly connected to one side of the rotating disk, and a handle is fixedly connected to one end of the rotating rod.

[0008] In a further embodiment, a second bearing is provided inside the housing, an adjusting rod is fixedly connected to the inner wall of the second bearing, a gear is installed in the middle of the adjusting rod, and the other end of the adjusting rod passes through the housing and extends to the outside of the housing.

[0009] In a further embodiment, one side of each support rod is fixedly connected to a limiting groove, the interior of each limiting groove is movably hinged to a limiting rod through a pin shaft, and one end of each limiting rod is movably hinged to a limiting seat through a pin shaft.

[0010] In a further embodiment, each of the support rods is a hollow structure, the outer surface of each of the first connecting rods is sleeved with a spring, the top end of each spring is connected to the bottom end of the support rod, and the bottom end of each spring is connected to the upper surface of the base.

[0011] In a further embodiment, a rack is fixedly connected to the bottom end of the second connecting rod, and the rack is meshed with the gear.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The device uses human power to open the support rod, so that the limit groove fixed on the surface of the support rod drives the limit rod and the limit seat to rise accordingly, and when the limit rod and the limit seat rise to be parallel to the limit groove, they will stop moving, thereby solving the problem that the angle of the bracket will increase due to loose fixation. When the device is pushed by human power, the universal wheel drives the device to move, and because of the cooperation of the spring, the support rod and the first connecting rod, it will play a shock-absorbing role when the device moves on an uneven road section, thereby solving the problem that the existing surveying and mapping instrument needs to fold the bracket when it is moved during use, which is troublesome to carry, increases time cost and is inconvenient to use.
