Description

Technical Field

[0001] This invention belongs to the field of engineering construction, and specifically relates to an angle divider for engineering applications. Background Technology

[0002] The current method for determining the bisectors of engineering angles uses a theodolite or total station. However, this requires that the target object at the theodolite or total station location is relatively small and that there is sufficient space for instrument placement. When the target object is too large or too tall, making direct measurement with a theodolite or total station impossible, auxiliary measurement methods must be used. These methods are complex, involve numerous calculations, and require multiple movements of the theodolite or total station. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an angle bisector for engineering purposes, so as to solve the problem of complicated operation in the current engineering construction when the target object is too large or too high.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An engineering angle divider is used to measure the angle bisectors of the angle formed by target objects in a triangular positional relationship. It includes a fixed module set on the target object, a measuring module set on the fixed module for measuring the angle formed by the target object, a laser module set on the measuring module for indicating the angle bisectors of the target object, and observation target modules for auxiliary positioning set on both sides of the measuring module.

[0006] Furthermore, the fixing module includes a first connecting part and a first fixing part. The first connecting part is used to connect to the measuring module, and the first fixing part is located on the side of the first connecting part away from the measuring module. The first fixing part is used to connect the first connecting part to the target object.

[0007] Furthermore, the measurement module includes a connecting part connected to the first connecting part, and a protractor for displaying the measurement angle is provided on the connecting part. The protractor is provided with an observation and aiming device for observing the two observation target modules to determine the measurement angle.

[0008] Furthermore, the protractor includes a protractor, a fixed observation arm, and a movable observation arm. The protractor is mounted on the connecting part, the fixed observation arm is fixedly mounted on the protractor, and the movable observation arm is rotatably mounted on the protractor with the center of the protractor as the center point.

[0009] Furthermore, the observation and aiming device is rotatably mounted at the center of the protractor, and calibration pointers are provided at the upper ends of both the fixed observation arm and the movable observation arm on the side furthest from the protractor.

[0010] Furthermore, there are two observation and aiming devices, which are respectively installed on the fixed observation arm and the movable observation arm.

[0011] Furthermore, the laser module includes a housing, a connecting plate is provided on the side of the housing near the protractor, the connecting plate is rotatably connected to the protractor with the center of the protractor as the point, a measuring pointer for indicating the scale of the protractor is provided on the side of the housing near the protractor, a laser head is provided on the housing, a battery connected to the laser head is provided inside the housing, and a charging port and a switch connected to the battery are provided on the housing.

[0012] Furthermore, a horizontal bubble meter is installed on the upper part of the outer casing.

[0013] Furthermore, the observation target module includes a second fixing part, a second connecting part, and a scale. The second connecting part is disposed on the second fixing part, and the scale is vertically disposed on the side of the second connecting part away from the second fixing part. A slider for indicating the scale is movably connected to the scale. The second fixing part is used to connect the second connecting part to a reference object.

[0014] The significant beneficial effects achieved by this invention are as follows:

[0015] 1. This invention discloses an angle bisector for engineering applications, used to measure the angle bisectors of targets in a triangular relationship. It includes a fixed module mounted on the target object, a measuring module mounted on the fixed module for measuring the angle formed by the target object, a laser module mounted on the measuring module for indicating the angle bisectors of the target object, and observation target modules for auxiliary positioning on both sides of the measuring module. This application uses the fixed module to mount the measuring module and laser module on the target object. The two observation target modules serve as auxiliary positioning points for the measuring module, mounted on reference objects on both sides of the target object to determine the measurement angle. The laser module indicates the angle bisectors of the target object. The measurement method is simple, the structure is simple and easy to carry and use, and it eliminates the need for a theodolite or total station, effectively solving the problem of cumbersome angle bisector determination operations when the target object is too large or too tall in current engineering construction.

[0016] 2. The first fixing part and the second fixing part can be provided as straps or rigid sleeves to facilitate fixing to a circular or regular polygonal target or reference object.

[0017] 3. The aiming and calibrating pointer can be aligned with the target module to adjust the angle between the fixed and movable observation arms. A single, flip-up aiming device allows for separate observation of the fixed and movable arms. A dual aiming device allows for separate observation by staff, making it more convenient to operate than a single device.

[0018] 4. The leveling bubble setting in the laser module allows for leveling of the laser module, while the battery, charging port, and switch settings facilitate continuous use of the laser head.

[0019] 5. The scale and slider settings can be used for adjacent reference objects of different diameters. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0033] To facilitate understanding by those skilled in the art, in this application, O is the target object, and A and B are reference objects on both sides of O. Example 1

[0034] like Figures 1-7 As shown, an engineering angle bisector is used to measure the angle bisector of a target object in a triangular positional relationship. Reference objects in a triangular positional relationship with the target object are set on both sides of the target object. The instrument includes a fixed module 1 installed on the target object, a measuring module 2 installed on the fixed module 1 for measuring the angle between AO and BO (i.e., the angle formed by the target object), a laser module 3 installed on the measuring module 2 for indicating the angle bisector of the target object, and observation target modules installed on reference objects A and B on both sides of the measuring module 2 for auxiliary positioning.

[0035] The fixing module 1 includes a first connecting part 5 and a first fixing part 6. The first connecting part 5 is used to connect to the measuring module 2. The first fixing part 6 is located on the side of the first connecting part 5 away from the measuring module 2. The first fixing part 6 is a strap, and the first connecting part 5 is a connecting block. Connecting buckles 51 are provided on both sides of the connecting block. The two ends of the strap are connected to the connecting buckles 51. A slide rail 52 is provided on the side of the connecting block away from the strap. The measuring module 2 is mounted on the first connecting part 5 via the slide rail 52. The first fixing part 6 is a strap, which can be detachably connected to the connecting buckles 51 on both sides of the first fixing part 6. The strap can be easily tied to the target object.

[0036] The measurement module 2 includes a connecting part 7 connected to the first connecting part 5. The connecting part 7 is equipped with a protractor for displaying the measured angle. An observation and aiming device 8 is mounted on the protractor. The observation and aiming device 8 is used to observe the angle formed by the two observation target modules. The connecting part 7 is a semi-circular plate with a groove 71 that matches the slide rail 52 on the first connecting part 5. The protractor includes a semi-circular protractor 9, which is fixedly mounted on the semi-circular plate. A fixed observation arm 10 is provided on one side of the protractor 9, and a movable observation arm 11 with the center of the protractor 9 as its rotatable point is rotatably connected to the protractor 9. The observation and aiming device 8... The aiming device 8 is rotatably connected to the center of the protractor 9 via a bracket. The aiming device 8 can be rotated horizontally and flipped to face different directions via the bracket. The fixed observation arm 10 and the movable observation arm 11 are both equipped with a calibration pointer 12 on the upper side of the end away from the protractor 9. By referring to the calibration pointer 12 on the fixed observation arm 10 or the movable observation arm 11, the aiming device 8 is aligned with the observation target module on the two reference objects to obtain the angle between AO and BO. The aiming device 8 can be a laser head, a graduated eyepiece or a telescope. The graduated eyepiece or telescope can easily find the reference point with the observation target module, which is convenient for measurement.

[0037] The laser module 3 includes a housing 13 located on the outer arc side of the protractor 9. A connecting plate 14 is provided on the side of the housing 13 closest to the protractor 9. The end of the connecting plate 14 furthest from the housing 13 is rotatably connected to the bottom of the connecting part 7 with the center of the protractor 9 as the pivot point. The housing 13 rotates around the protractor 9 on the outer side via the connecting plate 14. A slot 131 adapted to the outer arc of the protractor 9 is provided on the side of the housing 13 closest to the protractor 9. A measuring pointer 15 is provided on the side of the housing 13 closest to the protractor 9, located at the upper end of the protractor 9 to indicate the angle on the protractor 9. A laser head 16 is mounted on the upper end of the housing 13, rotatably mounted on the housing 13 via a bracket. An electrical connection is provided inside the housing 13 with the laser head 16. The battery 19 is connected, and the outer casing 13 is provided with a charging port 17 and a switch 18 connected to the battery 19. A level bubble meter 20 is installed on the upper end of the outer casing 13 on one side of the laser head 16. The laser module 3 is set to indicate the angle bisector of the target object. After the observation and aiming device 8 determines the angle between AO and BO through the movable observation arm 11 and the fixed observation arm 10, the angle of the target object's angle bisector is calculated by the angle. The outer casing 13 is moved to move the measuring pointer 15 to set the angle of the angle bisector. The laser head 16 emits a laser to indicate the angle bisector of the target object. The laser head 16 can be a cross laser or a line laser. The flip-out setting of the laser head 16 can facilitate the multi-angle display of the position of the angle bisector on the target object.

[0038] The observation target module includes a second fixing part 21, a second connecting part 22, and a scale 23. The second connecting part 22 is disposed on the second fixing part 21, and the scale 23 is vertically mounted on the second connecting part 22 on the side away from the second fixing part 21. A slider 24 for indicating the scale is slidably connected on the scale 23 along its length. The second fixing part 21 and the first fixing part 6, and the second connecting part 22 and the first connecting part 5 have the same structure. The second fixing part 21 is used to fix the second connecting part 22 on the reference object. By installing the two observation target modules on two adjacent reference objects of the target object respectively, the positioning points of the movable observation arm 11 and the fixed observation arm 10 are used to obtain the angle between AO and BO, and to determine the angle bisector of the target object. The fact that the second fixing part 21 and the first fixing part 6, and the second connecting part 22 and the first connecting part 5 have the same structure can facilitate mass production.

[0039] Instructions for use: Step 1: Fix the fixing module 11 onto the target object O. The cross-section of the target object O can be circular or a regular polygon. When it is circular, use a flexible fixing strap. Fix the first connecting part 5, the measuring module 2 and the laser module 3 onto the target object O through the first fixing part 6. Adjust the bubble level on the laser module 3 to make the entire device horizontal.

[0040] Step 2: Fix the two observation target modules to the adjacent reference objects A and B on both sides of the target object O through the second fixing part 21. Adjust and align the observation target modules so that the scale 23 is perpendicular to the tangent points of OA, OB and reference objects A and B. Keep the installation height as consistent as possible with the angle divider used in engineering. The cross-sections of reference objects A and B can be circular or regular polygons. If they are circular, use flexible fixing straps.

[0041] Step 3: Continuously observe the scale 23 with indicator slider 24 in the fixed observation target module on reference objects A and B through the observation and aiming device 8 of the measurement module 2. When the cross-sections of reference objects A and B are of equal diameter or their circumscribed circles are of equal diameter, adjust the movable observation arm 11 back and forth multiple times to make the readings of the scale 23 on reference objects A and B in the central line of sight of the observation and aiming device 8 consistent.

[0042] Step 4: When the cross sections of reference object A and reference object B or their circumscribed circles are not of equal diameter, first measure the difference in diameter between the cross sections of reference object A and reference object B or their circumscribed circles. Adjust the movable observation arm 11 back and forth multiple times until the difference in the reading of the scale 23 on reference objects A and B in the center line of sight of the observation device 8 is consistent with the diameter difference, which satisfies the requirements.

[0043] Step 5: When the movable observation arm 11 is adjusted to meet the measurement requirements, read the reading of the protractor 9 in the measurement module 2.

[0044] Step 6: Calculate the equidistant angle value according to the reading, and rotate the laser module 3 so that the scale indicated by its measuring pointer 15 is consistent with the calculated equidistant angle value.

[0045] Step 7: Turn on the power switch 18 of laser module 3. Its vertical laser line is the angle bisector.

[0046] Step 8: Rotate the laser head 16 to determine the location of the angle bisector of the target object along the laser line direction.

[0047] The observation principle involves placing the target module at points a and b on the reference object. The measurement module and laser module are fixed on the target object at point o via a fixing module. Simplified into a mathematical geometric diagram, the measured angle ∠α is formed by OA and OB. Due to the principle that opposite angles are equal, ∠β = ∠α. ∠β is read using a protractor. The angle ∠δ formed by the extensions of OC and OB is taken as ∠δ = ∠β / n, where n is an integer greater than 0. The formed angle ∠δ is the angle bisector.

[0048] In summary, this application uses a fixing module 1 to fix the measurement module 2 and the laser module 3 onto the target object. Two observation target modules are installed on both sides of the target object as auxiliary positioning points for the measurement module 2 to determine the measurement angle. The laser module 3 indicates the location of the angle bisector of the target object. The angle bisector is obtained based on the angle formed by the target object. The measurement method is simple, the structure is simple, and it is easy to carry and use. There is no need to use a theodolite or total station for measurement, which effectively solves the problem of complicated operation of angle bisector determination when the target object is too large or too high in current engineering construction.

[0049] Example 2

[0050] like Figure 8 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. The difference between this embodiment and embodiment 1 is that there are two observation devices 8 in this embodiment. The two observation devices 8 are respectively rotatably connected to the upper side of the fixed observation arm 10 and the movable observation arm 11 away from the protractor 9 by the bracket. The setting of two observation devices 8 is more convenient than one observation device 8, and observation can be carried out without rotating the observation device 8 back and forth. The installation orientation of the two observation devices 8 is consistent with the length direction of the fixed observation arm 10 and the movable observation arm 11 to ensure the accuracy of observation.

[0051] Example 3

[0052] like Figure 9 and Figure 10 As shown, the structure of this embodiment is generally similar to that of embodiment 1. The difference between this embodiment and embodiment 1 is that when the cross-section of the target object O or the reference objects A and B is a regular polygon, the first fixing part 6 and the second fixing part 21 are both rigid circular sleeves. The rigid circular sleeve is equipped with an adjustable buckle 26 for adjusting the size of the circular sleeve. The first connecting part 5 and the second connecting part 22 are both provided with a slide rail 52 that is adapted to the connecting part 7 and a circular sleeve mounting groove 25 that is adapted to the rigid circular sleeve.

[0053] Currently, the technical solution of this application has undergone pilot testing, which is a small-scale experiment before the product is mass-produced. After the pilot testing was completed, a user survey was conducted on a small scale, and the survey results showed that user satisfaction was high. Now, preparations have begun for the formal production and industrialization of the product (including intellectual property risk warning surveys).
