Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying and mapping, and in particular to a marking device used for on-site surveying and mapping of construction projects. Background Art

[0002] In the design, construction and management stages of a building project, it is necessary to conduct on-site surveying and mapping operations. The purpose is to accurately calibrate the plane position and elevation of each part of the building in accordance with the design requirements, so as to serve as the basis for construction and installation. In the surveying and mapping process, it is often necessary to conduct surveying and mapping work at a fixed location, so the accuracy requirements for the surveying and mapping location are very strict.

[0003] At present, when surveying and mapping on the construction site, the main method is to manually hold a bucket filled with lime powder and spread the lime powder to the measurement position to mark the measurement position to ensure the accuracy of the subsequent surveying and mapping results. However, the use of lime powder marking is greatly affected by the external environment. It is easy for the lime powder to deviate from the marked position on rainy days and windy weather, resulting in inaccurate measured positions after marking, which is not conducive to the accurate implementation of the subsequent surveying and mapping process. In addition, the single marking method also makes the flexibility of measuring position marking during construction site surveying and mapping poor. Utility Model Content

[0006] (II) Technical solution

[0007] The utility model is achieved through the following technical scheme: the utility model proposes a marking device for on-site surveying and mapping of construction projects, including a marking disk, a fixing rod is installed in the middle of the bottom end of the marking disk, four marking ropes are installed in a ring shape on the outer wall of the marking disk, each of the marking ropes is connected to a marking rod at one end away from the marking disk, a winding groove is provided on the marking rod at a position connected to the marking rope, a storage cavity is provided in the lower part of the marking rod, a discharge hole is provided at the bottom end of the storage cavity, a spiral rod is installed in the middle of the storage cavity, a cross handle is connected to the top end of the spiral rod, and a protective cap is also installed at the bottom end of the marking rod located at the discharge hole.

[0008] Furthermore, the marking disk is provided with four annular holes for fixing the marking rod.

[0009] By adopting the above technical solution, the socket can realize the convenient insertion and storage of the marking rod after use.

[0010] Furthermore, a feeding plug plate is installed at the feeding hole of the marking rod, and the feeding plug plate is a rubber plug.

[0011] By adopting the above technical solution, after the feeding plug plate is opened, the marked dry lime powder can be added into the storage cavity first.

[0012] Furthermore, the fixing rod is welded to the marking plate, and the bottom ends of the fixing rod and the marking rod are both pointed structures.

[0013] By adopting the above technical solution, such a design can ensure that when the marking plate and the marking rod are used for fixed-point marking, the marking rod and the fixing rod can be conveniently inserted into the soil at the construction process surveying site.

[0014] Furthermore, one end of the marking rope is connected to the marking disk in a bundled manner, and the other end of the marking rope is connected to the winding groove in a bundled manner.

[0015] By adopting the above technical solution, the marking rope can ensure that the marking rod is reliably connected to the marking disk, and under the action of the marking rope, the marking rod can be rotated around the fixed rod at the bottom end of the marking disk, thereby realizing the circular motion of the marking rod around the fixed rod, thereby ensuring the circular arc motion trajectory of the lime powder when spreading the lime powder.

[0016] Furthermore, the spiral rod passes through the top end of the marking rod and is rotatably connected to the marking rod, and the spiral rod is welded to the cross handle.

[0017] By adopting the above technical solution, the cross handle is rotated to rotate the spiral rod, which can ensure that the lime powder in the storage chamber can be fully discharged, so that the construction engineering surveying site can be marked with the help of the lime powder.

[0018] Furthermore, the protective cap is threadedly connected to the marking rod, and the protective cap is a hard steel cap.

[0019] By adopting the above technical solution, the protective cap is mainly used to seal and protect the discharge port at the bottom end of the marking rod. When it is necessary to mark the surveying site by spreading lime powder, the protective cap needs to be removed in advance.

A spiral rod 12 is installed in the middle of the storage chamber 10, and a cross handle 1 is connected to the top of the spiral rod 12. The cross handle 1 is rotated to rotate the spiral rod 12, which can ensure that the lime powder in the storage chamber 10 can be fully discharged, so that the construction engineering surveying and mapping site can be marked with the help of lime powder. A protective cap 5 is also installed at the bottom end of the marking rod 2 at the discharge hole 11. The protective cap 5 is mainly used to seal and protect the discharge port at the bottom end of the marking rod 2. When it is necessary to mark the surveying and mapping site by spreading lime powder, the protective cap 5 needs to be removed in advance.

[0029] like Figure 1-Figure 2 As shown, in this embodiment, four insertion holes 8 for fixing the marking rod 2 are provided in a ring shape on the marking disk 7, and the insertion holes 8 can realize the convenient insertion and storage of the marking rod 2 after use. A feeding plug plate 4 is also installed at the feeding hole of the marking rod 2, and the feeding plug plate 4 is a rubber plug. After opening the feeding plug plate 4, the dry lime powder in the mark can be added to the storage chamber 10 first.
