Abstract
Description
Technical Field
[0001] This utility model specifically relates to an integrated measuring device for a space frame structure ball rod, belonging to the field of measurement engineering. Background Technology
[0002] Measurement of space frame structures is primarily based on the different needs of the construction and service phases. During construction, measurement is a crucial quality control tool, ensuring the accuracy of member installation positions and node connections, preventing unreasonable structural stress due to positional deviations, and monitoring construction progress to promptly identify and adjust any delays. Furthermore, measurement can monitor structural deformation in real time during construction, ensuring construction safety. During service, measurement is used for structural health monitoring, regularly checking deformation and vibration characteristics to promptly detect damage and anomalies. Simultaneously, measurement data is a vital basis for safety assessments and maintenance decisions, helping to determine whether older space frame structures require reinforcement or component replacement to ensure long-term safe use. It also helps determine whether the dimensions of newly constructed space frame structures meet standards. Currently, there are no corresponding suitable tools for all of these testing processes. In high-altitude measurement operations of space frame structures, surveyors must climb to different locations for spot checks, generally facing the following problems:
[0003] 1. The inspection requires carrying a variety of tools, such as a total station, steel ruler, and angle ruler. Frequent tool changes are not only inconvenient to operate, but also easy to cause tools to fall, threatening the safety of personnel and equipment below.
[0004] 2. The complex structure of the space frame, the challenging angles of the measurement points, and the confined space or obstructed view in some areas make direct measurement with conventional tools difficult, affecting measurement accuracy and efficiency. These problems increase the difficulty and risk of high-altitude operations, requiring targeted solutions. Utility Model Content

Detailed Implementation
[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0027] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11This embodiment describes a space frame structure ball-and-stick integrated measuring device comprising a disc-shaped outer shell 1, a central drive component 3, and six measuring components 2. The six measuring components 2 are evenly arranged along the circumference of the disc-shaped outer shell 1. One end of each measuring component 2 is installed inside the disc-shaped outer shell 1, and the other end of each measuring component 2 is a measuring end. The measuring end of each measuring component 2 passes through one side of the disc-shaped outer shell 1 and is located outside the disc-shaped outer shell 1. The disc-shaped outer shell 1 and the central drive component 3 are coaxially arranged. One end of the central drive component 3 is a driving end, and the other end of the central drive component 3 passes through the disc-shaped outer shell 1. The other side meshes with each measuring element 2; each measuring element 2 includes a driven helical gear 2-1, a threaded rod 2-2, a slider 2-3, a clamping rod 2-4, and a bidirectional pointer 2-5. The driven helical gear 2-1 is disposed at one end of the threaded rod 2-2, and the other end of the threaded rod 2-2 is hinged to the disc-shaped housing 1. The threaded rod 2-2 is threadedly connected to the slider 2-3. The driven helical gear 2-1 and the threaded rod 2-2 are coaxially disposed. The slider 2-3 is slidably disposed on the disc-shaped housing 1. The upper end of the slider 2-3 is provided with a bidirectional pointer 2-5, and the lower end of the slider 2-3 is provided with a clamping rod 2-4.
[0028] The driven helical gear 2-1 is driven to rotate by the central drive component 3, which in turn drives the threaded rod 2-2 to rotate. The threaded rod 2-2 is threadedly connected to the slider 2-3. At this time, the slider 2-3 slides along the length of the threaded rod 2-2, thereby driving the clamping rod 2-4 and the bidirectional pointer 2-5 to move synchronously. This allows the bidirectional pointer 2-5 to follow the movement of the clamping rod 2-4 and point to different scale lines 1-1-3, thus achieving the purpose of directly obtaining the measurement value.
[0029] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. The disc-shaped outer shell 1 includes a disc shell 1-1 and a hand handle 1-2. The hand handle 1-2 is provided on the disc shell 1-1. The disc shell 1-1 and the hand handle 1-2 are coaxially arranged. A through hole 1-2-1 is machined on the hand handle 1-2. A cavity 1-1-1 is machined inside the disc shell 1-1. The cavity 1-1-1 is connected to the through hole 1-2-1. Six elongated holes 1-1-2 are machined along the circumference of the disc shell 1-1. The elongated holes 1-1-2 correspond one-to-one with the measuring piece 2. The elongated holes 1-1-2 are connected to the cavity 1-1-1. A slider 2-3 is slidably arranged inside the elongated holes 1-1-2. A threaded rod 2-2 is hinged to the inner wall of the elongated holes 1-1-2. A driven helical gear 2-1 is hinged inside the cavity 1-1-1.
[0030] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. The driven helical gear 2-1 meshes with the central driving component 3. The central driving component 3 includes a screwing component 3-1, a connecting rod 3-2, and a driving helical gear 3-3. One end of the connecting rod 3-2 is provided with the screwing component 3-1, and the other end of the connecting rod 3-2 is provided with the driving helical gear 3-3. The screwing component 3-1, the connecting rod 3-2, and the driving helical gear 3-3 are coaxially arranged. The connecting rod 3-2 passes through the through hole 1-2-1, and the driving helical gear 3-3 is hinged in the cavity 1-1-1. The driving helical gear 3-3 meshes with the driven helical gear 2-1.
[0031] By rotating the screwing component 3-1, the screwing component 3-1 drives the active helical gear 3-3 to rotate through the connecting rod 3-2, so that the active helical gear 3-3 simultaneously drives the six driven helical gears 2-1, thereby achieving the purpose of operating the six measuring components 2 at the same time, and making the data of this utility model accurate when measuring the node ball 6 or the rod 5.
[0032] Specific Implementation Method Four: This implementation method further defines Specific Implementation Method One, Two, or Three. Each elongated hole 1-1-2 has scale lines 1-1-3 machined on both sides of its top. Each elongated hole 1-1-2 has a groove 1-1-4 machined on both sides of its inner wall. Each slider 2-3 has a protrusion 2-3-1 machined on both sides. The groove 1-1-4 and the protrusion 2-3-1 slide in a one-to-one correspondence. The protrusion 2-3-1 slides in the groove 1-1-4, causing the slider 2-3 to move the bidirectional pointer 2-5. The bidirectional pointer 2-5 points to the scale line 1-1-3, which can intuitively provide measurement data. The measurement method is easy to standardize and operate.
[0033] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Method 1, 2, 3 or 4. An elastic sleeve 1-3 is provided on the hand handle 1-2. The elastic sleeve 1-3 is fitted onto the hand handle 1-2. The outer wall of the elastic sleeve 1-3 is machined with multiple strip grooves along its length. The elastic sleeve 1-3 increases the friction of the measuring person's hand, making it easier to rotate the screwing part 3-1.
[0034] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, or Five. The first screwing component 3-1 is replaced with a secondary helical gear 3-4. The secondary helical gear 3-4 meshes with the extension component 4. The extension component 4 includes a main helical gear 4-1, a cylindrical rod 4-2, a long rod 4-3, a second screwing component 4-4, an arc-shaped connecting strip 4-5, and a connecting cylinder 4-6. The connecting cylinder 4-6 is detachably connected to the hand handle 1-2. The top end of the connecting cylinder 4-6 is connected to one end of the arc-shaped connecting strip 4-5. The other end of the arc-shaped connecting strip 4-5 is set on the cylindrical rod 4-2. The long rod 4-3 passes through the cylindrical rod 4-2 and is hinged inside the cylindrical rod 4-2. One end of the long rod 4-3 is provided with the second screwing component 4-4, and the other end of the long rod 4-3 is provided with the main helical gear 4-1. The main helical gear 4-1 meshes with the secondary helical gear 3-4.
[0035] The angle between the extended component 4 and the central drive component 3 is 90°, which makes it easier for the measuring personnel to place the measuring component 2 vertically on the node ball 6 or the rod 5 in a horizontal position. The measuring personnel hold the cylinder rod 4-2 and rotate the screwing component 4-4 with the other hand. The screwing component 4-4 drives the long rod 4-3 to rotate inside the cylinder rod 4-2, so that the long rod 4-3 drives the main helical gear 4-1 to rotate. The main helical gear 4-1 meshes with the secondary helical gear 3-4, thereby driving the secondary helical gear 3-4 to rotate, and thus completing the purpose of the central drive component 3 driving the measuring component 2. This makes the operation of the measuring personnel more convenient and can also adapt to different measuring positions.
[0036] Working principle:
[0037] When measuring the diameter of node ball 6: Determine the node ball 6 to be measured, and then make the six clamping rods 2-4 wrap around the node ball 6. At this time, the six driven helical gears 2-1 are driven simultaneously by the central drive component 3. The driven helical gears 2-1 drive the threaded rod 2-2 to rotate. The threaded rod 2-2 is threadedly connected to the slider 2-3. At this time, the slider 2-3 moves along the length of the long hole 1-1-2 towards the driven helical gear 2-1, thereby retracting the six clamping rods 2-4 and clamping the node ball 6. At this time, the scale line 1-1-3 pointed to by the bidirectional pointer 2-5 is the radius of the node ball 6.
[0038] When measuring the diameter of rod 5: place rod 5 between the six clamping rods 2-4 so that rod 5 evenly divides the six clamping rods 2-4. Then, drive the six driven helical gears 2-1 simultaneously through the central drive member 3. Repeat the above operation to make the six clamping rods 2-4 retract simultaneously. Consider the two adjacent bidirectional pointers 2-5 and the center of the disc-shaped outer shell 1 as three points. The triangle formed by these three points is an equilateral triangle. Therefore, when the clamping rods 2-4 contact the outer wall of rod 5, the scale line 1-1-3 pointed to by the bidirectional pointers 2-5 is the diameter of rod 5.
