Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a measuring and positioning device for a construction site of a building project. Background Art

[0002] During the construction process, measurement and positioning are key steps to ensure accurate construction of buildings. These steps involve the use of a variety of high-precision measurement equipment, such as common total stations and theodolites, which also need to be installed and fixed with a tripod.

[0003] The utility model patent with authorization announcement number CN218754116U discloses a construction engineering surveying and setting-out device, which includes a theodolite, a tripod is arranged on one side of the theodolite; a theodolite seat is fixedly connected to one side of the theodolite, a tripod sleeve is fixedly connected to one side of the tripod, the theodolite seat is movably connected to the tripod sleeve, a rubber ring is arranged inside the theodolite seat, a rubber ring slot is opened inside the tripod sleeve, the rubber ring is adapted to the rubber ring slot, a screw is arranged on the outside of the tripod sleeve, the screw is threadedly connected to the tripod sleeve, and one end of the screw passes through the tripod sleeve and is movably connected to the rubber ring. Since the cross-section of the rubber ring is trapezoidal and the rubber ring is made of rubber, the rubber ring has a certain elasticity, so that the rubber ring also closes the channel for the lubricating oil to escape from the seat ring, so that the loss of lubricating oil can be reduced in the process of the theodolite driving the theodolite seat to rotate, saving the number of oiling times and the oiling cost; since a limit block is arranged on the outside of the tripod sleeve and a screw step is arranged on the outer sleeve of the screw, the limit block can block the screw step in the process of separation of the screw and the rubber ring, so that the problem of the screw being screwed out of the tripod sleeve can be avoided.

[0004] Although the construction engineering surveying and laying-out device can avoid the problem of the screw being unscrewed from the tripod sleeve, the tripod of the theodolite still has the following problems when being stored: since the multiple legs of the tripod are hinged, it is convenient to adjust the height of the theodolite during use, but after the measurement is completed, the multiple legs need to be folded and stored to improve the convenience of transportation and storage. In order to prevent the closed legs from spreading out, the traditional method is to bundle the multiple legs with cable ties, etc., but this operation method has the problems of inconvenient operation and poor fixing effect. In view of this, we propose a construction engineering construction site measurement and positioning device. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a construction site measurement and positioning device for a building project.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] The inner wall of the fixing seat is fixed with a fixing plate, and the multiple fixing plates are located at different horizontal heights, and the fixing plates are all provided with fixing holes; a bracket is fixed to the bottom end of the fixing plate at the bottom, and a fixing rod is passed through the opening of the bracket, and the top of the fixing rod passes through multiple fixing holes in sequence, and a slide plate that can be raised and lowered along the opening of the bracket is fixed to the outer wall of the fixing rod, and a spring for pressing the slide plate is also provided on the fixing rod.

[0010] Furthermore, a pull ring is fixed at the bottom end of the fixing rod, and the overall shape of the pull ring is ring-shaped.

[0011] Furthermore, the overall shape of the bracket is U-shaped, and the bracket is fixedly connected to the fixing plate by bolts.

[0015] Furthermore, the support plate is of a hollow structure, and the support plate is fixedly connected to the tip by bolts.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] By providing a fixing plate and a fixing rod on the tripod, when the multiple legs are folded and stored, the multiple fixing holes are located on the same axis. At this time, the fixing rod passes through the multiple fixing holes in sequence. Under the restriction of the fixing rod, the fixing plate can be restricted on the fixing rod, thereby limiting the multiple legs, so that the multiple legs will not loosen easily after being folded. This design not only improves the storage convenience of the tripod, but also ensures the fixing effect of the multiple legs. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-Figure 4As shown, the construction site measurement and positioning device of the construction project includes a measuring instrument 1, and a tripod 2 is fixed to the bottom end of the measuring instrument 1. The tripod 2 includes a top seat 20, and a plurality of connection grooves 201 are provided on the outer wall of the top seat 20; three supporting feet are provided below the top seat 20; the supporting feet include two symmetrical support rods 21, a connecting seat 22 is fixed between the top ends of the two support rods 21, and the connecting seat 22 is hinged to the connecting groove 201, and a fixed seat 23 is fixed between the bottom ends of the two support rods 21, and a sliding groove 231 is provided on the fixed seat 23, and a support plate 29 is slidably installed in the sliding groove 231, and a tip 291 is fixed to the bottom end of the support plate 29; the outer wall of the fixed seat 23 is also threadedly connected with an adjusting bolt 2 4, and the end of the adjusting bolt 24 is pressed against the support plate 29; the inner wall of the fixing seat 23 is fixed with a fixing plate 25, and the plurality of fixing plates 25 are located at different horizontal heights, and the fixing plates 25 are all provided with fixing holes 251; the bottom end of the fixing plate 25 located at the bottom is fixed with a bracket 26, and a fixing rod 27 is penetrated at the opening of the bracket 26, and the top of the fixing rod 27 passes through the plurality of fixing holes 251 in sequence, and the outer wall of the fixing rod 27 is fixed with a slide plate 271 that can be raised and lowered along the opening of the bracket 26, and the fixing rod 27 is also sleeved with a spring 28 for pressing against the slide plate 271.

[0028] In this embodiment, a pull ring 272 is fixed at the bottom end of the fixing rod 27, and the overall shape of the pull ring 272 is annular. The annular design of the pull ring 272 is convenient for the user to pull, which increases the convenience of use.

[0029] In this embodiment, the overall shape of the bracket 26 is U-shaped, and the bracket 26 is fixedly connected to the fixing plate 25 by bolts. The U-shaped overall shape provides good support and stability.
