Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a measuring instrument used in water supply engineering construction. Background Art

[0002] A water supply project is a project for laying water supply pipelines. When constructing a water supply project, it is necessary to use measuring instruments such as levels and theodolites to measure elevations, angles and other data to ensure the correct direction and position of the pipeline during the construction of the water supply project. Levels and theodolites need to be fixed to the ground through a tripod. In order to reduce the burden of carrying, a tripod is generally carried. Different project data are measured by connecting different measuring instruments and tripods. This requires repeated disassembly and installation of measuring instruments and tripods, and readjustment of the tripod and ground fixation and leveling, which is very inconvenient to operate. Therefore, an adjustable and easy-to-install measuring instrument is required during the construction of water supply projects.

[0003] Chinese patent document CN116608843B discloses a measuring instrument for water supply engineering construction, in which the transfer frame is fixed by connecting and fixing a plurality of measuring instruments through a tail connecting screw rod, and the switching operation of measuring instruments such as a level and a theodolite is realized by rotating the transfer frame, thereby eliminating the operation of disassembling and installing measuring instruments with different functions, eliminating the disassembly and installation of measuring instruments and tripods with different functions, and avoiding the need to readjust the tripod and the ground for fixing and leveling during the construction of water supply projects. The measuring instruments rotate to the inside of the outer protection box body as the transfer frame rotates, and the outer protection box body can protect a plurality of measuring instruments, eliminating the need for additional boxes for the measuring instruments, and eliminating the need to place the measuring instruments in the protection box body during the construction of water conservancy projects, thereby reducing the number of equipment carried, and the first guide slide groove and the second guide slide groove guide the central connection transfer frame and the measuring instrument to rotate outward when they are replaced, thereby reducing the diameter of the central connection transfer frame and the measuring instrument, reducing the diameter size of the outer protection box body, and reducing space occupancy.

[0004] The existing technology has the following problems:

[0005] When using the measuring instruments currently on the market, the installation steps of the measuring instruments and the tripod are relatively cumbersome and inconvenient to use. At the same time, in actual use, the existing measuring instruments are not easy to adjust the angle of the measuring instruments, which is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1-Figure 7As shown, a measuring instrument for water supply engineering construction includes a shell 1, a mounting assembly 3 and an adjusting assembly 4 are arranged on the front side of the shell 1, and the mounting assembly 3 is located above the adjusting assembly 4, an adjusting screw 5 is fixedly installed on the lower surface of the adjusting assembly 4, an outer surface of the adjusting screw 5 is threadedly connected to an internal threaded tube 6, and a tripod 7 is rotatably connected to the lower surface of the internal threaded tube 6, and a measuring instrument body 2 is arranged in the inner cavity of the shell 1, and the threaded action of the internal threaded tube 6 and the adjusting screw 5 facilitates the height adjustment of the measuring instrument body 2, and the adjusting assembly 4 includes a disc 41, and the disc 41 has a The lower surface is fixedly installed with the upper end of the adjusting screw 5, the lower surface of the inner cavity of the disc 41 is rotatably connected with the adjusting shaft 45, and the upper end of the adjusting shaft 45 extends to the top of the disc 41, the mounting assembly 3 includes a transverse plate 31, the rear side of the transverse plate 31 is fixedly installed with the front side of the outer shell 1, a connecting screw 32 is arranged on the front side of the lower surface of the transverse plate 31, the outer surface of the connecting screw 32 is threadedly connected with the inner surface of the adjusting shaft 45, a socket 36 is provided on the right side of the connecting screw 32, and the left end of the socket 36 extends to the left side of the adjusting shaft 45, and the inner cavity of the socket 36 is plugged with an insertion rod 33 passing through the adjusting shaft 45.

[0029] By adjusting the threaded action of the shaft 45 and the connecting screw 32, the housing 1 can be easily installed, making the installation of the measuring instrument body 2 more flexible. The measuring instrument body 2 is an instrument such as a level or a theodolite. The tripod 7 is inserted into the ground. The distance and angle of the pipeline trench excavation in the water supply project construction are measured through the measuring instrument body 2 to ensure that the direction of the water supply project construction is consistent with the direction of the drawing. When the angle of the measuring instrument body 2 needs to be adjusted, the housing 1 is driven to rotate by the adjusting component 4, thereby driving the measuring instrument body 2 to rotate, which is convenient for adjusting the angle of the measuring instrument. The threaded action of the internal threaded tube 6 and the adjusting screw 5 makes it convenient to adjust the height of the measuring instrument body 2.

[0030] like Figure 2-Figure 4 As shown, a worm wheel 42 is fixedly mounted on the outer surface of the adjusting shaft 45 , and a worm 43 passing through the disc 41 is rotatably connected to the left side of the inner cavity of the disc 41 , and the front side of the worm 43 is meshed with the rear side of the worm wheel 42 .

[0031] The worm 43 is rotated, and when the worm 43 is meshed with the worm wheel 42, the worm wheel 42 drives the adjusting shaft 45 to rotate. The adjusting shaft 45 drives the housing 1 to rotate through the mounting assembly 3, thereby driving the measuring instrument to rotate, so as to facilitate the adjustment of the angle of the measuring instrument. Since the worm wheel 42 is self-locking when meshing with the worm 43, after determining the angle of the housing 1, the adjusting shaft 45 can be maintained in the corresponding position without the need for an additional limiting structure to limit it.

[0032] like Figure 2-Figure 4 As shown, a hand wheel 44 is fixedly mounted on the right end of the worm 43, and the material of the hand wheel 44 is silicone.

[0033] When the worm 43 is rotated, the hand wheel 44 made of silicone material can play an anti-slip role.

[0034] like Figure 2 , Figure 3 As shown, a wear-resistant sleeve 47 is embedded and installed on the upper surface of the disc 41, and the material of the wear-resistant sleeve 47 is rubber.

[0035] The wear-resistant sleeve 47 reduces the wear between the adjusting shaft 45 and the disc 41, thereby extending the service life thereof.

[0036] like Figure 5-Figure 7 As shown, a positioning column 35 is fixedly installed at the lower end of the connecting screw 32, and a positioning groove 46 is opened on the upper surface of the bottom of the adjusting shaft 45. The inner surface of the positioning groove 46 is plugged into the outer surface of the positioning column 35, and the lower ends of the positioning groove 46 and the positioning column 35 are both truncated cone structures.

[0037] The connecting screw 32 is positioned by the positioning groove 46 and the positioning column 35 .

[0038] like Figure 5-Figure 7 As shown, a stud 37 is fixedly installed on the left end of the insertion rod 33, and a hexagonal nut 34 is threadedly connected to the outer surface of the stud 37.

[0039] The insert rod 33 is passed through the adjusting shaft 45 and the connecting screw 32, and then the hexagonal nut 34 is threadedly connected to the stud 37, so as to limit the connecting screw 32 and the adjusting shaft 45 to prevent the connecting screw 32 and the adjusting shaft 45 from rotating when the measuring instrument is adjusting the angle.

[0040] The working principle of the present invention is as follows: through the threaded action of the adjusting shaft 45 and the connecting screw 32, the housing 1 is easily installed, so that the installation of the measuring instrument and the tripod 7 is more flexible. The insert rod 33 passes through the adjusting shaft 45 and the connecting screw 32, and then the hexagonal nut 34 is threadedly connected to the stud 37. The measuring instrument body 2 is an instrument such as a level or a theodolite. The tripod 7 is inserted into the ground. The distance, angle, etc. of the pipeline trench excavation in the water supply project construction are measured through the measuring instrument body 2 to ensure that the direction of the water supply project construction is consistent with the direction of the drawing. When it is necessary to adjust the measuring instrument body 2, the measuring instrument body 2 can be adjusted to the desired position. When the angle of the body 2 is adjusted, the worm 43 is driven to rotate by the hand wheel 44. Under the meshing of the worm 43 and the worm wheel 42, the worm wheel 42 drives the adjusting shaft 45 to rotate. The adjusting shaft 45 drives the housing 1 to rotate through the mounting assembly 3, thereby driving the measuring instrument to rotate, which is convenient for adjusting the angle of the measuring instrument. Since the worm wheel 42 is self-locking when meshing with the worm 43, after determining the angle of the housing 1, the adjusting shaft 45 can be maintained in the corresponding position without adding an additional limiting structure to limit it. The threaded action of the internal threaded tube 6 and the adjusting screw 5 makes it easy to adjust the height of the measuring instrument body 2.

[0041] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
