Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to a measuring instrument for geological engineering surveying. Background Technology

[0002] Geological engineering surveying instruments are specialized tools used in geological exploration, surveying, and engineering construction to assist in detailed measurements and data collection of topography, landforms, groundwater, and other aspects. Depending on the purpose of the measurement, accuracy requirements, and the measurement environment, different surveying instruments are used. These are primarily electronic surveying instruments that integrate multiple functions such as angle measurement, distance measurement, and data storage. They enable precise measurements of location, coordinates, and other information.

[0003] Most existing geological engineering surveying instruments rely on manual hand-holding and support frames to ensure stability and facilitate data reading. However, traditional triangular support frames require adjustment and rotation when used on sloping ground, making setup cumbersome and impacting work progress. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a measuring instrument for geological engineering surveying.

[0005] This utility model is achieved by the following technical solution: a measuring instrument for geological engineering surveying, including a measuring instrument base, an adjustment support assembly is provided on the top of the measuring instrument base, and a limit component is provided inside the adjustment support assembly.

[0006] The adjusting support assembly includes a fixing block, which is fixedly connected to the top of the measuring instrument base. A limiting groove is formed on the top of the fixing block, and a limiting ball is rotatably connected to the inner wall of the limiting groove. A multi-stage connecting rod is fixedly connected to the surface of the limiting ball. A connecting rod is fixedly connected to the end of the multi-stage connecting rod away from the limiting ball, and a second limiting ball is fixedly connected to the end of the connecting rod away from the multi-stage connecting rod. A second fixing block is rotatably connected to the outer wall of the second limiting ball, and a measuring instrument support base is fixedly connected to the end of the second fixing block away from the second limiting ball. A central limiting block is fixedly connected to the top surface of the measuring instrument base, and a second limiting groove is formed on the top of the central limiting block. A third limiting ball is rotatably connected to the inner wall of the second limiting groove, and a connecting rod is fixedly connected to the top of the third limiting ball. A sliding rod housing is slidably connected to the outer wall of the connecting rod, and the end of the sliding rod housing away from the connecting rod is fixedly connected to the bottom of the measuring instrument support base.

[0007] As a further improvement to the above solution, three fixing blocks are provided, and the three fixing blocks are evenly arranged around the central limiting block. Three multi-stage connecting rods are also provided, and the three multi-stage connecting rods are evenly arranged around the central limiting block.

[0008] As a further improvement to the above solution, three connecting rods are provided, and the three connecting rods are evenly arranged around the central limiting block. Three fixing blocks are also provided, and the three fixing blocks are evenly arranged around the central limiting block.

[0009] The above technical solution involves placing the measuring instrument base on the ground, allowing it to conform to the curvature of the ground. Then, by pulling the measuring instrument support, the support moves the fixed block two, causing the limiting ball two to rotate inside the fixed block two. Simultaneously, the limiting ball two pulls the connecting rod, which in turn pulls the multi-stage connecting rod, causing the multi-stage connecting rod to rotate the limiting ball within the limiting groove opened in the fixed block.

[0010] As a further improvement to the above solution, the limiting component includes a limiting hole, which is opened on the surface of the slide rod housing. A limiting pin is slidably connected to the inner wall of the limiting hole. A bottom fixing plate is fixedly connected to the surface of the connecting rod, and a support bolt is threadedly connected to the inner wall of the bottom fixing plate.

[0011] As a further improvement to the above solution, a plurality of limiting holes are provided, which are evenly distributed on the surface of the slide rod housing, and four support bolts are provided, which are symmetrically arranged with the connecting rod as the center.

[0012] As a further improvement to the above solution, a T-shaped groove is formed on the surface of the measuring instrument support base, a T-shaped slider is slidably connected to the inner wall of the T-shaped groove, the measuring instrument is fixedly connected to the top of the T-shaped slider, a limit groove is formed on the inner wall of the measuring instrument support base, a limit spring is fixedly connected to the right side of the inner wall of the limit groove, a limit slider is fixedly connected to the end of the limit spring near the T-shaped slider, the outer wall of the limit slider is slidably connected to the inner wall of the limit groove, and the outer wall of the limit slider is slidably connected to the surface of the T-shaped slider.

[0013] As a further improvement to the above solution, two limiting slides are provided, and the two limiting slides are symmetrically arranged with the T-shaped slider as the center. There are two limiting sliders, and the two limiting sliders are symmetrically arranged with the T-shaped slider as the center.

[0014] With the above technical solution, when the height of the measuring instrument support needs to be adjusted and the measuring instrument support needs to be fixed, the limiting pin is inserted into the limiting hole opened in the slide rod housing, so that the limiting pin passes through the slide rod housing and supports the top of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention places the measuring instrument base on the ground, allowing it to conform to the ground's curvature. Pulling the measuring instrument support causes the support to move the second fixing block, rotating the second limiting ball within it. Simultaneously, the limiting ball pulls a connecting rod, which in turn pulls a multi-stage connecting rod, causing the limiting ball to rotate within the limiting groove of the fixing block. This allows the evenly spaced multi-stage connecting rods to adjust their lengths according to the ground's inclination. As the measuring instrument support moves upward, it moves the sliding rod housing, whose inner wall slides upward along the outer wall of the connecting rod. Simultaneously, the connecting rod causes the third limiting ball to rotate along the limiting groove of the central limiting block. Therefore, when installing the measuring instrument base and support, there is no need to repeatedly rotate the measuring instrument base; simply pulling the support vertically upward is sufficient. This provides the device with great flexibility and adaptability to various terrains.

[0017] This invention, after adjusting the height of the measuring instrument support base, requires fixing it by inserting a limiting pin into the limiting hole in the slide rod housing. The limiting pin penetrates the slide rod housing and supports the top of the connecting rod. Then, by rotating the support bolts, the bolts move downwards along the bottom fixing plate, causing the bottom of the support bolts to contact the top of the central limiting block. This ensures that the four support bolts, according to the inclination angle of the connecting rod, contact the surface of the central limiting block to varying degrees, thus supporting the connecting rod and preventing the limiting ball from rotating during measurement. This increases the stability and applicability of the equipment during measurement. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

A limiting ball 211 is rotatably connected to the inner wall of the limiting groove 210. A connecting rod 212 is fixedly connected to the top of the limiting ball 211. A sliding rod housing 213 is slidably connected to the outer wall of the connecting rod 212. The end of the sliding rod housing 213 away from the connecting rod 212 is fixedly connected to the bottom of the measuring instrument support base 208.

[0028] There are three fixed blocks 201, which are evenly arranged around the central limiting block 209. There are also three multi-stage connecting rods 204, which are evenly arranged around the central limiting block 209.

[0029] There are three connecting rods 205, which are evenly arranged around the central limiting block 209. There are also three fixing blocks 207, which are evenly arranged around the central limiting block 209.

[0030] The limiting component 3 includes a limiting hole 301, which is formed on the surface of the slide rod housing 213. A limiting pin 302 is slidably connected to the inner wall of the limiting hole 301. A bottom fixing plate 303 is fixedly connected to the surface of the connecting rod 212. A support bolt 304 is threadedly connected to the inner wall of the bottom fixing plate 303.

[0031] Several limiting holes 301 are provided, and the several limiting holes 301 are evenly distributed on the surface of the slide rod housing 213. Four support bolts 304 are provided, and the four support bolts 304 are symmetrically arranged with the connecting rod 212 as the center.

[0032] The measuring instrument support 208 has a T-shaped groove 305 on its surface. A T-shaped slider 306 is slidably connected to the inner wall of the T-shaped groove 305. A measuring instrument 307 is fixedly connected to the top of the T-shaped slider 306. A limiting groove 308 is provided on the inner wall of the measuring instrument support 208. A limiting spring 309 is fixedly connected to the right side of the inner wall of the limiting groove 308. A limiting slider 310 is fixedly connected to the end of the limiting spring 309 near the T-shaped slider 306. The outer wall of the limiting slider 310 is slidably connected to the inner wall of the limiting groove 308 and the surface of the T-shaped slider 306.

[0033] There are two limiting slides 308, which are symmetrically arranged with the T-shaped slider 306 as the center. There are two limiting sliders 310, which are symmetrically arranged with the T-shaped slider 306 as the center.

[0034] The implementation principle of a geological engineering surveying instrument in this embodiment is as follows: The instrument base 1 is placed on the ground, allowing it to conform to the ground's curvature. Then, by pulling the instrument support 208, the support 208 drives the second fixing block 207, causing the second limiting ball 206 to rotate within the fixing block 207. Simultaneously, the limiting ball 206 pulls the connecting rod 205, which in turn pulls the multi-stage connecting rod 204. This causes the multi-stage connecting rod 204 to rotate the limiting ball 203 within the limiting groove 202 of the fixing block 201. This allows the evenly spaced multi-stage connecting rods 204 to be adjusted in length according to the ground's inclination curvature, thus allowing the instrument support 204 to rotate. As the measuring instrument support 208 moves upward, the measuring instrument support 208 drives the sliding rod housing 213. The inner wall of the sliding rod housing 213 slides upward along the outer wall of the connecting rod 212. At the same time, the connecting rod 212 drives the limiting ball 211 to rotate along the limiting groove 210 opened by the central limiting block 209. This allows the measuring instrument base 1 to be repeatedly rotated when installing the measuring instrument base 1 and the measuring instrument support 208. Simply pull the measuring instrument support 208 vertically upward. This gives the equipment great flexibility and adaptability to various terrains. After the height of the measuring instrument support 208 is adjusted, it needs to be supported and fixed. This is done by inserting the limiting pin 302 into the sliding rod housing 212. The limiting hole 301 is opened in the 13th hole, so that the limiting pin 302 passes through the inside of the slide rod housing 213 to support the top of the connecting rod 212. Then, by rotating the support bolt 304, the support bolt 304 moves downward along the inside of the bottom fixing plate 303, so that the bottom of the support bolt 304 contacts the top of the central limiting block 209. Thus, the four support bolts 304 contact the surface of the central limiting block 209 to different degrees according to the inclination angle of the connecting rod 212, thereby supporting the connecting rod 212 and preventing the connecting rod 212 from driving the limiting ball 211 to rotate during the measurement process. This increases the stability and applicability of the equipment during the measurement process. Then, by using the T-shaped slider 306... The measuring instrument 307 is installed along the T-shaped groove 305 provided in the measuring instrument support 208. Simultaneously, the T-shaped slider 306 compresses the limiting slider 310 inside the limiting groove 308, thereby compressing the limiting spring 309 inside the limiting groove 308. Then, when the T-shaped slider 306 drives the measuring instrument 307 completely into the T-shaped groove 305, the T-shaped slider 306 disengages from the surface of the limiting slider 310. This allows the limiting slider 310 to limit the surface of the T-shaped slider 306 under the push of the limiting spring 309, preventing the measuring instrument 307 from disengaging from the measuring instrument support 208 during measurement. This increases the flexibility and applicability of the equipment, facilitating the installation and removal of the measuring instrument 307.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
