Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering measurement, in particular to a curve surveying and mapping device for construction engineering measurement. Background Art

[0002] When measuring and drawing curves in construction engineering, traditional manual methods or simple measuring tools are usually used. For example, a level ruler, a tape measure, and a plumb line are usually used to measure the horizontal and vertical positions of a series of characteristic points on the curve, and then the point-to-point line method is used for measurement and drawing. These methods are not only inefficient but also difficult to ensure accuracy. Therefore, people have developed methods such as the existing authorization announcement number CN 215217609. U's "Curve Surveying Device for Construction Engineering Measurement" is designed to improve curve surveying operations. It includes a surveying ruler and an arc-shaped member detachably connected to one side of the ruler. The arc-shaped member and the ruler are equipped with a measuring assembly for measuring curve angles. The measuring assembly includes an adjustment rod movably connected to one side of the ruler and an angle disc that rotates in conjunction with the adjustment rod. The adjustment rod has a screw hole with a locking bolt threadedly connected to the inner thread of the screw hole on the side facing the ruler. The threaded portion of the locking bolt is threadedly sleeved with a sliding block, which is slidably connected to an arc-shaped groove on the outer wall of the arc-shaped member. A pen clamp assembly is provided on the outer periphery of the adjustment rod, and a protective structure is provided on the outer surface of the arc-shaped member. This curve surveying device for construction engineering measurement has a simple structure and is easy to carry.

At the same time, although it can improve portability to a certain extent, its portability still has room for improvement. To this end, in response to the above-mentioned deficiencies, the present utility model proposes a curve surveying device for construction engineering measurement.

The support shaft 21 is fixedly mounted on the front side of the base 1, and the circular plate 2 is mounted on the support seat for damped rotation. An angle disk 25 is fixedly mounted on the front side of the base 1, and a pointer 24 is fixedly mounted on the outer circumference of the circular plate 2. The pointer 24 is adapted to the angle disk 25, which is convenient for users to observe the angle of rotation of the circular plate 2 relative to the base 1. The two mounting boxes 3 are fixedly mounted on the base 1 and the circular plate 2 respectively. A rotating shaft 32 is rotatably mounted in the mounting box 3, and the rotating shaft 32 is mounted on the rotating shaft A winding roller 31 is provided on the fixed sleeve, and two steel rulers 34 are fixed and wound on the winding rollers 31 respectively. A coil spring 33 centered on the rotating shaft 32 is fixedly installed between the rotating shaft 32 and the inner wall of the mounting box 3, which can realize the automatic winding operation of the steel ruler 34 when the limit on the steel ruler 34 is released. Two card slots are provided on the front side of the base 1, and the same U-shaped limit block 5 is clamped and installed in the two card slots. The limit block 5 is fixedly installed with an anti-slip pad 51 that abuts against the corresponding steel ruler 34. After the steel ruler 34 on the base 1 is pulled out to the required length, it can be limited by the cooperation of the limit block 5 and the anti-slip pad 51;

[0033] In order to facilitate the drawing of curves and to be able to clamp and fix drawing pens of different diameters, a support ring 4 is fixedly installed on the end of the steel ruler 34 on the circular plate 2 away from the circular plate 2, and two screw rods 41 located on the same axis are threadedly installed on the support ring 4. The ends of the two screw rods 41 that are close to each other are rotatably installed with clamping blocks 42, and the ends of the two screw rods 41 that are away from each other are fixedly sleeved with adjusting wheels, and the sides of the two clamping blocks 42 that are away from each other are fixedly installed with multiple sliding rods 43 that are slidably connected to the support ring 4 and are arranged to be parallel to the screw rods 41.

[0034] In this embodiment, in order to prevent the protrusion generated when the angle ruler is installed on the base 1 from having a negative impact on the steel ruler 34 on the base 1, an annular groove is opened on the front side of the base 1, and the angle disk 25 is located in the annular groove, and the front side of the angle disk 25 is flush with the front side of the base 1.

[0035] In this embodiment, in order to ensure a more stable rotation of the circular plate 2, a plurality of guide pins 22 are fixedly installed on the rear side of the circular plate 2, and a guide groove 23 arranged in a ring shape is opened on the front side of the base 1 with the support shaft 21 as the center, and a plurality of guide pins 22 are respectively slidably installed in the corresponding guide grooves 23.

[0036] In this embodiment, in order to fix the relative position between the circular plate 2 and the base 1 as needed, a limiting bolt 201 is threadedly installed on the circular plate 2 , and the rear end of the limiting bolt 201 abuts against the front side of the base 1 .

Then, according to the length of the curve to be measured, pull out the steel ruler 34 to the appropriate position, and temporarily fix the steel ruler 34 through the limit block 5 and the anti-slip pad 51. At the same time, the operator can rotate the circular plate 2 and adjust the angle between the two steel rulers 34 through the cooperation of the pointer 24 and the angle disk 25, so as to accurately measure the angle of the curve. During the measurement process, the clamping block 42 on the support ring 4 can be adjusted to adapt to the required diameter of the drawing pen, thereby ensuring the flexibility and accuracy of the drawing.

[0040] After the measurement is completed, the steel ruler 34 can be automatically reeled in by utilizing the elastic force of the coil spring 33 , and then the protective cover 12 can be covered on the base 1 . The hanging ring 11 provided can facilitate users to carry the device more conveniently.
