Description

Technical Field

[0001] The present application relates to the technical field of mine surveying engineering, and specifically to a level instrument used in mine surveying engineering. Background Art

[0002] In mining surveying projects, the level is a commonly used instrument. It is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points based on the leveling principle. The main components include a telescope, a tube level (or compensator), a vertical axis, a base, and a foot screw.

[0003] When an existing level is mounted on a support frame for measurement, the support frame is generally perpendicular to the ground. However, in some special measurement tasks (such as on terrain with restrictive obstacles), the vertically mounted support frame may cause the level to be unable to accurately observe the target point, thereby increasing the measurement error and reducing the overall measurement accuracy. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to propose a level for mine surveying engineering to solve the problems existing in the prior art.

[0005] In order to achieve the above purpose, the utility model provides a level for mining surveying engineering, including a base, a partially threaded rod fixedly penetrated through the inner side of the base, the outer surface of the partially threaded rod is rotatably connected to a turntable, the outer surface of the turntable is provided with a slot, the top of the turntable is fixedly connected to a support rod, the top of the support rod is fixedly connected to a mounting platform, the top of the mounting platform is provided with a level, and the outer surface of the base is provided with a screw locking mechanism.

[0006] Preferably, the screw locking mechanism includes a screw sleeve threaded on the outer surface of a portion of the threaded rod, and the end of the screw sleeve away from the rotary table is fixedly connected to a knob. The screw locking mechanism can be used to adjust the inclination angle of the support rod together with the mounting table, and can prevent them from loosening or deflecting.

[0007] Preferably, a ratchet is provided on the outer surface of the screw sleeve, and a first fixed shaft is fixedly connected to the outer surface of the base.

[0008] Preferably, the outer surface of the first fixed shaft is rotatably connected to a pawl, and the outer surface of the pawl is provided with a shift plate.

[0009] Preferably, the outer surface of the base is fixedly connected to a second fixed shaft, and a spring pick is provided on the second fixed shaft. The spring pick is usually made of a material with high elastic limit, fatigue limit and impact toughness.

[0010] Preferably, a storage drawer is provided on the mounting platform.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This level used in mine surveying projects introduces an inclination adjustment function, allowing the support rod and the erection platform to flexibly cope with various terrain conditions. Especially in the presence of restrictive obstacles (such as steep slopes, rock protrusions, etc.), the level can be adjusted to the appropriate position to ensure that the level can accurately observe the target point, greatly broadening the scope of application of the surveying work.

[0013] 2. The level used in mining surveying projects has a locking mechanism between the support rod and the mounting platform, such as a ratchet and pawl, which ensures stability after adjustment, effectively prevents equipment instability caused by shaking or external force, and improves safety during the measurement process.

[0018] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] See also Figure 1-3 A level for mining surveying engineering includes a base 1, a partially threaded rod 2 is fixedly penetrated on the inner side of the base 1, a rotary table 3 is rotatably connected to the outer surface of the partially threaded rod 2, a slot 4 is provided on the outer surface of the rotary table 3, a support rod 5 is fixedly connected to the top of the support rod 5, a setting platform 6 is fixedly connected to the top of the setting platform 6, a level 7 is provided on the top of the setting platform 6, and a screw locking mechanism is provided on the outer surface of the base 1.

[0020] Through the above technical solution, when the level 7 is measuring on the mounting platform 6, the inclination angle of the support rod 5 can be adjusted according to needs. This process requires rotating the turntable 3 along part of the threaded rod 2, and the screw sleeve 8 can be used to stably limit the turntable 3 by screwing the locking mechanism.

[0021] Specifically, the screw locking mechanism includes a screw sleeve 8 threadedly sleeved on the outer surface of a portion of the threaded rod 2 , and a knob 9 is fixedly connected to one end of the screw sleeve 8 away from the rotary table 3 .

[0022] With the above technical solution, the portion where the threaded rod 2 contacts the turntable 3 is not designed with threads, and the screw sleeve 8 can move along the axial direction during the rotation of the threaded rod 2 , thereby tightly pressing against the turntable 3 .

[0023] Specifically, a ratchet 10 is fixedly mounted on the outer surface of the screw sleeve 8 , and a first fixed shaft 11 is fixedly connected to the outer surface of the base 1 .

[0024] Through the above technical solution, the ratchet 10 will rotate synchronously with the rotation of the screw sleeve 8, and the pawl 12 limits the ratchet 10, which will cause the screw sleeve 8 to be limited synchronously.

[0025] Specifically, the outer surface of the first fixed shaft 11 is rotatably connected to a pawl 12 , and the outer surface of the pawl 12 is provided with a shift plate 13 .

[0026] Through the above technical solution, the tip portion of the pawl 12 is usually designed with a shape and size that matches the teeth of the ratchet 10 to ensure that it can be stably inserted between the teeth. This shape matching enables the pawl 12 to be more easily inserted into the ratchet 10 and remain stable when supported by the spring paddle 15.

[0027] Specifically, a second fixed shaft 14 is fixedly connected to the outer surface of the base 1 , and a spring pick 15 is provided on the second fixed shaft 14 .

[0028] Through the above technical solution, the spring pick 15 exerts a continuous supporting force on the pawl 12 through its elastic force, so that the pawl 12 can maintain a certain position or posture. This supporting force helps the pawl 12 to stably engage between the teeth when it contacts the ratchet 10.

[0029] Specifically, a storage drawer 16 is provided on the mounting platform 6 .

[0030] Through the above technical solution, the storage drawer 16 can be partially withdrawn. This design is to facilitate the operator to place the computer on it, so as to better collect and organize data, which reflects the humanized processing.

[0031] Working principle: During the mine surveying process, the device measures the height difference between two points through the level 7. Taking into account that in some special measurement tasks (such as on terrain with restrictive obstacles), the vertically erected support frame may cause the level 7 to be unable to accurately observe the target point, thereby increasing the measurement error and reducing the overall measurement accuracy. At this time, the inclination angle of the support frame can be adjusted, that is, the rotary table 3 is rotated along part of the threaded rod 2, thereby driving the support rod 5 and the mounting platform 6 to adjust the inclination angle. After the rotary table 3 is rotated to a certain angle, the paddle plate 13 needs to be pushed outward so that the pawl 12 rotates along the first fixed axis 11 against the spring paddle 15 until the tip of the pawl 12 is no longer stuck in the teeth of the ratchet 10. After that, the knob 9 can be rotated to make the screw sleeve 8 rotate along the part of the threaded rod 2. During this process, the screw sleeve 8 will move axially along the part of the threaded rod 2 until the screw sleeve 8 is tightly stuck in the groove 4 opened on the surface of the rotary table 3, thereby stably holding and limiting the rotary table 3. Finally, the plate 13 is released, and the pawl 12 is elastically supported by the spring paddle 15. The pawl 12 will be re-engaged between the teeth of the ratchet 10, thereby stably limiting the ratchet 10, that is, stabilizing the rotary table 3 to prevent the screw sleeve 8 from shaking and affecting the stability of the rotary table 3, that is, allowing the support rod 5 together with the top mounting platform 6 to remain stable after adjusting to the corresponding inclination angle, thereby avoiding restrictive obstacles and allowing the level 7 to accurately measure.

[0032] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
