Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically to a geological measuring device suitable for different terrains. Background Technology

[0002] A geological surveying tripod is an indispensable piece of equipment in geological exploration and topographic surveying. It typically consists of three adjustable-length support legs and a top platform, used to stably support surveying instruments such as levels, theodolites, or total stations. The tripod legs are generally made of high-strength, lightweight materials, such as aluminum alloy or carbon fiber, to ensure durability and portability. In geological surveying, the stability of the tripod is crucial. It ensures that surveying instruments remain level in complex terrain and harsh environments, thereby improving the accuracy and reliability of measurements. Furthermore, the top platform of the tripod is usually designed with adjustable screws and fine-tuning devices for precise adjustment of the position and angle of the surveying instruments.

[0003] CN222230142U discloses a geological surveying device suitable for different terrains, including a mounting plate. A measuring instrument body is fixedly mounted on the top surface of the mounting plate, and a support plate is fixedly connected to the top surface of the mounting plate. Several support sleeves are rotatably connected to the side of the support plate. The advantages of this invention are: by pushing the slider downwards along the guide rod until the insertion pin passes through the through hole and extends out of the support rod, the insertion pin can be exposed. The insertion pin can then be inserted into the ground. Furthermore, the extension length of the insertion pin can be adjusted. When conducting surveying operations in areas with harder geology, the slider can control the insertion pin to retract into the groove. Finally, the threaded post is inserted into the threaded sleeve and rotated. Through threaded transmission, the threaded post is installed into the inner wall of the threaded sleeve. Then, the support base plate is placed on the ground, increasing the contact area between the tripod and the ground, thus improving the stability of the tripod.

[0004] The aforementioned geological surveying device, suitable for different terrains, requires manual disassembly / installation of components (such as connectors and threaded sleeves) to adapt to different terrains. This involves many steps and parts are easily lost. Furthermore, when retrieving connectors, soil is easily introduced, and long-term accumulation can cause the mechanism to jam.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-5This utility model provides a technical solution: a geological surveying device suitable for different terrains, including a support plate 1, a measuring instrument body 11 mounted on the top of the support plate 1, three sets of foot rods 12 connected in a ring at the bottom of the support plate 1, a hollow foot sleeve 13 fixedly connected to the bottom of each foot rod 12, a turning component 2 set inside the hollow foot sleeve 13, the turning component 2 including a threaded rod 23 rotatably connected inside the hollow foot sleeve 13, a ground support component 3 set outside the threaded rod 23, the ground support component 3 including a ground support frame 32 that can extend from the bottom of the hollow foot sleeve 13 and support the ground, and a rolling component 4 set at the bottom of the hollow foot sleeve 13, the rolling component 4 including a ball bearing 411 that can drive the hollow foot sleeve 13 and the support plate 1 as a whole to slide and move on the ground;

[0025] This design adopts an integrated terrain adaptation mechanism and a self-cleaning and sealing design to solve the problems of cumbersome function switching and easy jamming of the mechanism caused by soil accumulation in the existing technology.

[0026] Please see Figure 3 The screwing assembly 2 also includes a lower connecting post 22, which is fixedly connected to the top of the threaded rod 23. A screwing sleeve 21 is fixedly connected to the end of the lower connecting post 22 away from the threaded rod 23. The screwing assembly 2 also includes a rubber ring 212, which is fixedly connected to the bottom of the screwing sleeve 21. The rubber ring 212 is in contact with the inner wall of the hollow foot sleeve 13.

[0027] This design prevents foreign objects such as dust from entering the hollow foot sleeve 13 through the annular groove 131;

[0028] Please see Figure 3 The screwing assembly 2 also includes a protective layer 211, which is distributed in a ring on the outside of the screwing sleeve 21;

[0029] The friction force of the operator turning the screw sleeve 21 is increased by providing a protective layer 211 on the outside of the screw sleeve 21.

[0030] Please see Figure 5 The hollow foot sleeve 13 has an annular groove 131 on its side wall, which corresponds to the position of the screw sleeve 21. The bottom of the hollow foot sleeve 13 has a first threaded groove 132 in the center, and the bottom of the hollow foot sleeve 13 has inlet and outlet grooves 133 through the first threaded groove 132 on both sides.

[0031] The support plate 1 also includes a scraper 1331, which is fixedly connected to the inside of the inlet / outlet groove 133;

[0032] The rolling assembly 4 can be disassembled and assembled through the first threaded groove 132;

[0033] When the ground support frame 32 is retracted into the hollow foot sleeve 13 at the inlet / outlet slot 133, the scraper 1331 inside the inlet / outlet slot 133 can scrape off the soil attached to the surface of the ground support frame 32, thereby preventing soil and other foreign objects from entering the hollow foot sleeve 13 along with the ground support frame 32.

[0034] Please see Figure 4 The ground support component 3 includes a sliding sleeve 31 and a second threaded groove 312. The second threaded groove 312 is opened on the inner side of the sliding sleeve 31. The sliding sleeve 31 is threaded to the outer side of the threaded rod 23 through the second threaded groove 312. A limiting strip 311 is symmetrically fixedly connected to the outer side of the sliding sleeve 31. The sliding sleeve 31 and the limiting strip 311 are integral and match the shape of the inner groove of the hollow foot sleeve 13.

[0035] By providing a limiting strip 311 on the outside of the sliding sleeve 31, lateral displacement of the sliding sleeve 31 inside the hollow foot sleeve 13 can be avoided.

[0036] Please see Figure 4 The ground support frame 32 is fixedly connected to the bottom of the sliding sleeve 31, and the ground support frame 32 corresponds to the position of the inlet / outlet groove 133;

[0037] Please see Figure 5 The rolling assembly 4 also includes a base 41, the bottom of which is rotatably connected to the ball 411, and a threaded post 42 is fixedly connected to the top of the base 41. The threaded post 42 matches the first threaded groove 132, and the base 41 is threadedly connected to the first threaded groove 132 through the threaded post 42.

[0038] This design allows for quick assembly and disassembly of the base 41 and ball bearings 411 at the bottom of the hollow foot sleeve 13.

[0039] The working principle and usage process of this utility model are as follows:

[0040] After the hollow foot sleeve 13 at the bottom of the measuring instrument body 11 is unfolded, the screw sleeve 21 located at the annular groove 131 of the hollow foot sleeve 13 can be screwed, which causes the screw sleeve 21 to drive the lower connecting column 22 and the threaded rod 23 to rotate inside the hollow foot sleeve 13. At this time, the sliding sleeve 31 threaded to the outside of the threaded rod 23 can drive the ground support frame 32 to move downward inside the hollow foot sleeve 13 until the ground support frame 32 extends out from the inlet and outlet groove 133. This design allows the ground support frame 32 to replace the hollow foot sleeve 13 in contact with the ground, thereby increasing the stability of ground support.

[0041] Similarly, when the support plate 1 and the measuring instrument body 11 are in the transport state, the screw sleeve 21 can be twisted in reverse to allow the support frame 32 to be retracted into the hollow foot sleeve 13. This design can prevent the support frame 32 from contacting external objects and causing damage.

[0042] In particular, when the support plate 1 and the measuring instrument body 11 are moved short distances on a smooth surface, the support frame 32 can be retracted into the hollow foot sleeve 13, and the ball bearing 411 can be used to roll and contact the ground, thereby allowing the support plate 1 and the measuring instrument body 11 to slide quickly to the target measurement position.

[0043] For the consumable ball bearing 411, this design provides a first threaded groove 132 at the bottom of the hollow foot sleeve 13. The ball bearing 411 can be quickly installed and removed from the bottom of the hollow foot sleeve 13 by threaded connection between the threaded post 42 and the first threaded groove 132, so that the damaged ball bearing 411 can be replaced separately later.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
