Description

Technical Field

[0001] The utility model relates to the technical field of precision measuring equipment, in particular to a shell structure node installation precision measuring device. Background Art

[0002] In modern engineering construction, shell structures are widely used in the construction of stadiums, office building roofs, and industrial plants. The quality and precision of these shell structures have a crucial impact on the performance, safety, and service life of the products. Therefore, accurately measuring the installation accuracy of the shell structure nodes is a key link in ensuring product quality. With the continuous development of construction technology, especially in the construction of grid shells involving multiple buildings, such as the construction of the G60 Science and Technology Innovation Cloud Corridor roof shell, the measurement requirements for the installation accuracy of the shell structure nodes are becoming increasingly stringent. Not only do they require high-precision measurement results, but they also require fast and efficient measurement methods to meet the needs of large-scale production and high-quality production.

[0003] In the prior art, some common shell structure node installation accuracy measurement equipment adopts more traditional mechanical structures and measurement principles. For example, some devices use a measuring mechanism based on the lever principle, which amplifies the measured displacement or angle change by rotating the lever, and then displays the measurement results through a dial or pointer. Some other devices use a guide rail and slider structure, install the measuring probe on the slider, and measure different positions of the shell by moving the slider on the guide rail. In addition, some more complex devices use a gear transmission mechanism to transmit power through the meshing of gears to achieve precise movement and positioning of the measuring probe. The measurement principle of these devices is mostly based on physical contact measurement, that is, the measuring probe is in direct contact with the shell structure, and the displacement or deformation of the measuring probe is used to reflect the installation accuracy of the shell structure node.

[0004] During the measurement process, the existing shell structure node installation accuracy measurement equipment requires multi-directional angle adjustment of the measurement probe due to the different shapes and positions of the shell structures. However, the existing measurement equipment can often only perform angle adjustment in a single direction, which not only increases the difficulty and time cost of measurement, but also easily leads to an increase in measurement errors, thereby affecting the accuracy and reliability of the measurement results. Therefore, a shell structure node installation accuracy measurement device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 2The present invention provides an embodiment of a shell structure node installation accuracy measuring device, comprising a base plate 1, the side wall of the base plate 1 being rotatably connected to a support leg 2, the support leg 2 being rotatable relative to the base plate 1. This rotatable connection method facilitates the device to adjust its own support state in different usage scenarios to adapt to different ground surfaces or installation environments. The upper surface of the base plate 1 is fixedly connected to a connecting block 6, the side wall of the connecting block 6 is fixedly connected to a mounting plate 7, the side wall of the mounting plate 7 is provided with a measuring instrument 11, the measuring instrument 11 is an existing device and will not be described in detail here, the side wall of the mounting plate 7 is provided with an adjustment component, the leg 2 is provided with a telescopic component, the lower surface of the base plate 1 is fixedly connected to a fixed column 3, the side wall of the fixed column 3 is slidably connected to a sliding ring 4, the side wall of the sliding ring 4 is rotatably connected to a rotating bar 5, one end of the rotating bar 5 is rotatably connected to the side wall of the leg 2, the rotatable connection between the rotating bar 5, the sliding ring 4 and the leg 2 can coordinate the motion relationship between the various components when the leg 2 is telescoped or rotated, and ensure the overall stability of the device. The adjustment assembly includes a fixed plate 18, the side wall of which is fixedly connected to the side wall of the mounting plate 7. A motor 19 is fixedly connected to the side wall of the fixed plate 8, and a rotating block 10 is fixedly connected to the output end of the motor 9. Starting the motor 9 can rotate the rotating block 10, thereby driving the measuring instrument 11 to rotate left and right, achieving horizontal angle adjustment of the measuring instrument 11, facilitating the measurement of shell structural nodes at different positions. A fixed plate 2 is fixedly connected to the side wall of the mounting plate 7, and a motor 2 is fixedly connected to the side wall of the fixed plate 2 12. A rotating block 2 is fixedly connected to the output end of the motor 2 13. When the motor 2 13 is started, it can drive the rotating block 2 14 to rotate. The rotational connection between the rotating block 2 14 and the measuring instrument 11 allows the measuring instrument 11 to rotate up and down, achieving vertical angle adjustment of the measuring instrument 11, further improving the flexibility of the measuring instrument 11 in measuring angle measurement. The side wall of the rotating block 10 is rotatably connected to the side wall of the measuring instrument 11, and the side wall of the measuring instrument 11 is rotatably connected to the inside of the rotating block 2 14. This connection method ensures that the measuring instrument 11 can achieve stable and accurate angle adjustment under the drive of the motor 1 9 and the motor 2 13;

[0035] When using the device for measurement, first place the device in a suitable position, then slide the sliding ring 4 down. As the sliding ring 4 slides down along the fixed column 3, since it is rotatably connected to the rotating bar 5, it will change the angle of the rotating bar 5, causing the rotating bar 5 to rotate. The rotation of the rotating bar 5 will apply an outward force to the support leg 2, thereby unfolding the support leg 2. After the support leg 2 is unfolded, it can increase the contact area between the device and the ground, improve the stability of the device, provide a stable support environment for subsequent measurements, and perform fixed support. Then, the measuring instrument 11 is started to scan the node part of the shell structure. The measuring instrument 11 uses its own measurement principle and sensor to perform a comprehensive scan of the shell structure node surface and obtain point cloud data of the node surface. These point cloud data contain the spatial coordinate information of each point on the node surface and are the basis for subsequent analysis. The data is then processed by software, which uses specific algorithms, such as fitting and analyzing the collected point cloud data, to obtain node dimensional information. During the measurement process, motor 19 can be activated. Once activated, its output drives the fixedly connected rotating block 10 to rotate. The rotation of rotating block 10, through its rotational connection with measuring instrument 11, drives measuring instrument 11 to rotate left and right. This left and right rotation allows measuring instrument 11 to cover a wider horizontal angle range and scan data at different horizontal positions of the node. Alternatively, motor 213 can be activated to drive rotating block 214. The power output of motor 213 is transmitted to rotating block 214. Due to the rotational connection between measuring instrument 11 and rotating block 214, measuring instrument 11 rotates up and down, allowing measuring instrument 11 to adjust its angle in the vertical direction, thereby achieving a full-scale scanning of the structural node. Full-scale scanning can avoid measurement blind spots and obtain a more comprehensive and high-precision node model. This high-precision node model can more accurately reflect the actual conditions of the shell structure node and provide more reliable data for installation accuracy assessment.

[0036] Reference Figure 3-Figure 5The telescopic assembly includes a sliding leg 15, the side wall of the sliding leg 15 is slidably connected to the inside of the support leg 2, and a fixing hole 16 is opened inside the sliding leg 15. The side wall of the support leg 2 is fixedly connected to a mounting sleeve 17, and the mounting sleeve 17 is slidably connected to a connecting column 18. The connecting column 18 can slide in the mounting sleeve 17, and one end of the connecting column 18 is rotatably connected to a rotating handle 19. The rotating handle 19 is convenient for the operator to apply external force. The side wall of the connecting column 18 is sleeved with a spring 20, one end of the spring 20 is fixedly connected to the inside of the mounting sleeve 17, and the other end of the spring 20 is fixedly connected to the side wall of the connecting column 18. The spring 20 plays the role of reset and auxiliary fixation. The other end of the connecting column 18 is fixedly connected to a card block 21, which cooperates with the fixing hole 16 to fix the position of the sliding leg 15 in the support leg 2, ensuring the stability of the support leg 2 after the length is adjusted, and preventing the sliding leg 15 from sliding due to vibration and other reasons during the use of the equipment, thereby affecting the normal use and measurement accuracy of the equipment. The side wall of the clamping block 21 is slidably connected to the inside of the fixing hole 16. This sliding connection mode enables the clamping block 21 to be smoothly inserted into or out of the fixing hole 16, thereby achieving adjustment and fixation of the length of the leg 2.

[0037] When the sliding leg 15 needs to be adjusted, the first step is to rotate the rotating handle 19. The rotation of the rotating handle 19 can easily transmit external force to the connecting column 18, causing it to pull the connecting column 18 to slide. The connecting column 18 slides within the mounting sleeve 17. This sliding method ensures that the connecting column 18 moves in the predetermined direction, thereby squeezing the spring 20. After being squeezed, the spring 20 will elastically deform and store elastic potential energy. During the squeezing process of the spring 20, the block 21 connected to the connecting column 18 will move along with the connecting column 18, causing the block 21 to disengage from the fixing hole 16. After the block 21 is separated from the fixing hole 16, it loses its fixing effect on the sliding leg 15. The sliding leg 15 can now move freely. At this time, the length of the sliding leg 15 can be adjusted by sliding the sliding leg 15 downward. Sliding the sliding leg 15 can change the overall length of the support leg 2 to adapt to different measurement height requirements or uneven ground conditions. When it slides to the appropriate length, the rotating handle 19 is rotated again. The rotation of the rotating handle 19 again changes the direction of the external force. , the connecting column 18 moves in the opposite direction under the action of the new external force. This movement causes the spring 20 to lose its extrusion. The spring 20 uses its own stored elastic potential energy to restore its original shape, and during the recovery process, pushes the block 21 to slide back into the fixing hole 16. After the block 21 re-enters the fixing hole 16, the sliding leg 15 is fixed. This fixing method can ensure that the sliding leg 15 will not slide at will during use, thereby ensuring that the support leg 2 remains horizontal. Keeping the support leg 2 horizontal is very important for the stability of the entire equipment. It can ensure the accuracy of the measuring instrument 11 during the measurement process and avoid measurement errors caused by the tilt of the support leg 2.

[0038] Working principle: When using the device for measurement, first place the device in a suitable position, then lower the sliding ring 4 to rotate the rotating bar 5, and then unfold the legs 2 for fixed support, then start the measuring instrument 11 to scan the node part of the shell structure, obtain the point cloud data of the node surface, and then process the data through software to obtain the size information of the node. During the measurement process, you can start the motor 19 to drive the rotating block 10 to rotate, thereby driving the measuring instrument 11 to rotate left and right, or you can start the motor 2 13 to drive the rotating block 2 14 to rotate, thereby measuring the measuring instrument 11. It rotates up and down to achieve an all-round scanning of the structural nodes and obtain a more comprehensive and high-precision node model. When the sliding leg 15 needs to be adjusted, first turn the rotating handle 19 to pull the connecting column 18 to slide, and then squeeze the spring 20 to make the block 21 disengage from the fixing hole 16 and lose the fixation of the sliding leg 15. At this time, the length of the sliding leg 15 can be adjusted by sliding it down. When it slides to the appropriate length, turn the rotating handle 19 again to make the spring 20 lose its extrusion and push the block 21 to slide back into the fixing hole 16 to fix the sliding leg 15 and ensure that the support leg 2 remains level.
