Description

Technical Field

[0001] The utility model relates to the technical field of measuring and setting out, in particular to a civil engineering measuring and setting out device. Background Art

[0002] The preliminary work of building construction includes cleaning, leveling the site and measuring and setting out the lines. Construction positioning is carried out according to the building design drawings. After the building positioning piles are set, the surveying personnel of the construction unit, the person in charge of the construction site and the supervisor jointly participate in the line setting and measurement work. During the line setting process, the construction personnel are required to measure the construction site.

[0003] A Chinese patent with announcement number CN220649521U discloses a civil engineering measurement and layout equipment. Through the setting of the shell, handle, and ground nails, the overall space occupied by the civil engineering measurement and layout equipment is small during use. It can be used by directly inserting it into the ground, and it is easy to carry and use, thereby improving the measurement and layout efficiency. At the same time, through the setting of the retracting mechanism, the measuring tape can be squeezed during the retracting process to avoid gaps in the measuring tape when retracting, thereby ensuring the stability of the retracting.

[0004] The above solution improves the stability of the measuring tape during winding by using a stopper against the measuring tape. However, the measuring tape inevitably rubs against the stopper, which reduces its service life. Furthermore, the measuring tape is only manually controlled by a crank, making it inconvenient for workers to perform other operations. Therefore, we provide a civil engineering surveying and setting-out device to address these issues. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-4 As shown, the utility model provides a technical solution: a civil engineering measurement and layout device, including a housing, a rotating shaft 5, a wire pressing assembly, a mounting block 16 and two supports 9.

[0033] The housing includes a storage box 1 , an inlet and outlet pipe 2 and a limiting pipe 3 , and the storage box 1 is connected to the limiting pipe 3 through the inlet and outlet pipe 2 .

[0034] The rotating shaft 5 is rotatably connected to the storage box 1, and a measuring tape 6 is wound on the rotating shaft 5, and the measuring tape 6 forms a wire coil on the rotating shaft 5. The end of the measuring tape 6 away from the rotating shaft 5 passes through the inlet and outlet tubes 2 and the limiting tube 3 in sequence and extends to the outside of the limiting tube 3. A guide roller 7 is rotatably connected to the storage box 1, and the guide roller 7 is used to guide the measuring tape 6 when it is extended from the storage box 1. The outer surface of the measuring tape 6 is designed with scale lines, and the extension length of the measuring tape 6 can be adjusted according to needs. A motor 4 is installed on the storage box 1, and the output shaft of the motor 4 is installed on the rotating shaft 5. There are many ways to rotate the rotating shaft 5. The rotating shaft 5 can be directly driven to rotate by turning the handle, and the rotating shaft 5 can also be driven to rotate by the output shaft of the motor 4.

[0035] The wire pressing assembly is arranged on the storage box 1, and is used to elastically contact the measuring tape 6 to compact the wire roll. The wire pressing assembly includes a linkage rod 18 slidably connected to the storage box 1, one end of the linkage rod 18 is fixedly connected to a mounting seat 19, and a supporting roller 20 is rotatably connected to the mounting seat 19.

[0036] When the measuring tape 6 is retracted or extended, the diameter of the wire coil will change, and the mounting seat 19 will always move closer to the wire coil under the elastic action of the first support spring 22 itself, so that the abutment roller 20 is pressed against the wire coil, and the abutment roller 20 rotates to tighten the measuring tape 6 when it is retracted or extended, thereby avoiding misalignment of the wire coil.

[0037] Two supports 9 are arranged in the limiting tube 3, and the two supports 9 are rotatably connected to the squeezing rollers 10. The limiting tube 3 is provided with a distance adjustment component for adjusting the distance between the two squeezing rollers 10, and the limiting is completed by adjusting the distance between the squeezing rollers 10 and the measuring tape 6.
