Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a novel rapid measurement positioning device. Background Art

[0002] Surveying is a science with a long history developed from human production practice. It is a means for humans to fight against nature. There are records in ancient times that "travel by car on land, travel by boat on water, travel by sled on mud, travel by sedan chair on mountain, use a plumb line on the left, have rules, carry the four seasons, open the nine states, connect the nine roads, fill the nine lakes, and cross the nine mountains." These are actually the functions of engineering surveying.

[0003] A total station is a device that uses the principle of light reflection to perform calculations by combining electromagnetic wave distance measurement with horizontal plate angle measurement. It is widely used in construction surveying and mapping.

[0004] However, there is a disadvantage of the total station when performing measurement operations, as follows:

[0005] When you need to accurately locate a point, you need to first enter the coordinates and elevation parameters into the total station host, and manually move the small prism, repeatedly moving the small prism according to the deviation calculated by the host each time for precise positioning. On average, you need to move the prism 6 times for one plane positioning point, which is very time-consuming.

[0006] In some scenarios, when the target point is located in a special position, or the total station is located in a special position, such as a major traffic artery, and the small prism needs to be moved too many times, it is easy to be interfered with by other external factors, such as the need to avoid vehicles and people in time. Because a problem occurs in a certain operation, the entire process will be interrupted and need to be restarted, which greatly affects efficiency. Utility Model Content

[0007] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a novel measurement and rapid positioning device which reduces the number of small prism movements and improves operating efficiency and positioning accuracy.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new type of measurement and rapid positioning device, including a compass component and a scale component;

[0009] The compass component serves as a center point component, and is used to form a center origin and serve as a reference point for orientation indication;

[0010] The scale assembly includes eight scales, which are distributed at equal angles around the compass assembly, and the zero point of each scale coincides with the position of the compass assembly.

[0011] The scale values ​​drawn on the scale serve as indicator points for positioning the prism rods.

[0012] Preferably, the width of the scale is 1 cm-2 cm.

[0013] Preferably, the length of the ruler is 30cm-35cm.

[0014] Preferably, the minimum unit of the scale is 1 mm.

[0015] Preferably, the scale is fixedly connected to the compass assembly.

[0016] Preferably, the scale is hinged to the compass assembly.

[0017] Preferably, the scale is pluggably connected to the compass assembly.

[0018] Preferably, the eight scales are an integrally formed plate structure.

[0019] Preferably, the scale assembly is made of steel sheet or iron sheet.

[0020] Preferably, the compass assembly is fixed to the center of the plate structure by bolts or gluing.

[0021] This utility model offers substantial advantages and advancements over existing technologies. Specifically, it provides a scale reference for prism movement. During measurement, based on the X and Y axis deviation values ​​reported by the operator, the operator determines the orientation using the compass in the center of the positioning device. The operator then moves the prism rod according to the scale of the positioning device, accurately locating the plane point. This significantly reduces the need for the operator to frequently move the prism, shortens measurement time, and improves efficiency and positioning accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0025] like Figure 1 As shown, a novel measurement and rapid positioning device includes a compass component 1 and a scale component 2.

[0026] The compass assembly 1 is used as a center point assembly to form the center origin and as a reference point for azimuth indication. The main function of the compass assembly 1 is to provide azimuth information and determine the azimuth information of the prism rod 3 according to the coordinate deviation information reported by the main surveyor. Figure 1 The dots on the prism rod 3 are only used to indicate their positions, and the positions are not limited to those shown in the figure.

[0027] The scale assembly 2 includes eight scales, which are distributed at equal angles around the compass assembly 1. The zero point of each scale coincides with the point where the compass assembly is located. The width of the scale is 1cm-2cm, the length is 30cm-35cm, and the minimum unit is 1mm, which basically meets the measurement requirements.

[0028] The scale values ​​drawn on the scale serve as the indicating points for positioning the prism rod 3 .

[0029] In order to ensure that the relative position relationship between the scale assembly 2 and the compass assembly 1 is accurate and stable, the scale is fixedly connected to the compass assembly. To avoid precision errors caused by assembly, the eight scales are an integrally formed plate structure, such as a steel sheet or an iron sheet. The compass assembly 2 is fixed to the center of the plate structure by bolts or glue.

[0030] In other embodiments, for easy storage, the scale and the compass assembly are hinged, or the scale and the compass assembly are pluggable and connected to facilitate transfer.

[0031] Technical principle description:

[0032] Generally speaking, prisms are auxiliary equipment used for positioning. During the measurement process, the accuracy of the prism point must be ensured first.

[0033] During the specific operation, the main surveyor operates the total station, the auxiliary personnel operates the prism rod 3, and the main surveyor observes the position of the prism rod 3 through the total station.

[0034] During the measurement process, the operator determines the XY axis deviation values ​​reported by the surveyor, uses the compass component in the positioning device to determine the orientation, and then moves the prism rod 3 according to the positioning device's scale to accurately locate the plane point. This significantly reduces the need for the surveyor to frequently move the prism, shortens measurement time, and improves efficiency and positioning accuracy.

[0035] This device was experimentally verified during the construction of pre-embedded bolts for equipment at the Xingshan County Waste Incineration Power Generation Project. The plant required numerous pre-embedded bolts for the lower steel structures and equipment, and the installation error of the pre-embedded bolts was required to be controlled within 2mm. Traditional positioning methods are time-consuming for measurement and positioning, so our department used a total station and a level in conjunction with this new rapid positioning device for measurement and positioning. This not only ensured installation accuracy but also shortened the measurement and positioning operation time.

[0036] First, a drawing of a stainless steel circular positioning scale was drawn, and the measuring device was manufactured according to the drawing. After the manufacturing was completed, it was verified on site to ensure its measurement and positioning accuracy. During the construction of the factory, the layout of all embedded parts was carried out using a station instrument, a level instrument and a new measuring device;

[0037] Then, on the short column reinforcement frame where the reinforcement binding construction has been completed, a total station, a level and a new measuring device are used to lay out the vertical and horizontal axes. The prism is placed on the circular scale for positioning. During the measurement process, the prism is directly moved according to the circular measuring scale based on the XY axis deviation value feedback from the main measuring personnel. Finally, the position of the embedded steel plate is determined and the steel plate is welded to the short column reinforcement. After welding is completed, the position and level of the steel plate are checked, and then the short column concrete is poured.

[0038] After that, assemble the mounting frame, check the relative positions of the four bolt holes, accurately determine the position of the mounting frame, and weld the mounting frame to the embedded steel plate;

[0039] Finally, a positioning steel plate is welded vertically above and below the bolt, and then four fine-tuning bolts are installed on the channel steel around the bolt hole to accurately locate the plane position of the embedded bolt and control the installation error within 2mm.

[0040] Finally, it should be noted that: The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
