Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of borehole verification, and more specifically, to a verification device for bolt connection holes on an ultra-large installation platform. Background Technology
[0002] In the installation system of large equipment, the extra-large installation platform (or installation base) is the core foundation supporting the main structure of the equipment, and its stability and precision directly determine the operational efficiency of the entire equipment. To achieve a firm connection between the main body of the equipment and the platform, multiple connection holes need to be pre-machined on the surface of the platform. The accuracy of these hole positions is a key prerequisite for subsequent bolt tightening and structural alignment. Currently, the machining of connection holes for such ultra-large platforms mainly relies on large-span drilling equipment with gantry structures. Although such equipment can meet the machining needs of large-size platforms, due to factors such as mechanical operation errors and platform deformation under load, the drilled connection holes often have problems such as hole position misalignment and hole diameter deviation. If the hole position verification is skipped and the installation process proceeds directly, it may result in bolts not being able to be inserted, forced alignment of components causing stress, or even more serious issues such as abnormal noise and excessive vibration in the equipment, and even potential safety hazards. Traditional verification methods rely on manual measurement: workers must use tools such as measuring tapes and total stations to obtain the coordinates of each hole, and then manually compare them with the theoretical values on the design drawings. This method is not only cumbersome, but also limited by the skill level and sense of responsibility of the operators, and is easily affected by reading errors and record omissions. Therefore, developing a dedicated device that can perform high-precision and rapid verification of connection holes on ultra-large platforms has become an urgent need to solve the current pain points in the industry.

Detailed Implementation
[0016] Example The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 5As shown, the verification device for bolt connection holes on the extra-large installation platform surface in this embodiment includes a platform 10, a plurality of connection holes 11 opened on the platform 10, a limiting post 21 locked in the connection hole 11, a connecting rod 22 rotatably connected to the limiting post 21, a positioning block 23 slidably connected to the connecting rod 22, and a ranging device 24 disposed on the positioning block 23; the axial direction of the limiting post 21 is perpendicular to the length direction of the connecting rod 22, and the positioning block 23 is attached to the side of the platform 10; the ranging device 24 is arranged facing the adjacent ranging device 24. Specifically, in use, the limiting post 21 is inserted into the pre-drilled connecting hole 11. Then, the connecting rod 22 is rotated so that the positioning block 23 is attached to the side of the platform 10, and the connecting rod 22 is perpendicular to the side of the platform 10. After the limiting post 21 is inserted into both connecting holes 11 simultaneously, and both positioning blocks 23 are fully attached to the side wall of the platform 10, the distance measuring device 24 can be used to measure the precise distance between two adjacent positioning blocks 23. The distance between two adjacent connecting holes 11 can be measured and compared with the pre-designed distance to calculate whether the error is within the allowable range. The first limiting post 21 is removed from the connecting hole 11 and then inserted into the second connecting hole 11 to continue the subsequent connecting hole 11 measurement operation. This method is relatively simple to operate and does not require highly skilled or precise operators to obtain accurate values quickly and efficiently. It can efficiently verify the opening accuracy of the connecting hole 11. It should be noted that this device is only applicable to platforms 10 with flat sidewalls, and the spacing between the connecting holes 11 and the platform 10 is relatively uniform.
[0017] The ranging device 24 in this embodiment includes a receiving plate 241 disposed on the side of the positioning block 23 away from the platform 10, and a rangefinder 242 disposed on one side of the receiving plate 241; one rangefinder 242 is positioned facing the ranging plate of the adjacent ranging device 24. Specifically, the rangefinder 242 can use laser ranging or infrared ranging. When using infrared ranging, a visible red light can be emitted to indicate the ranging position. Usually, if the position of the connecting hole 11 is accurate, the red light will illuminate the exact center of the receiving plate 241. If the position of the connecting hole 11 is offset, the red light will not illuminate the exact center of the receiving plate 241. Therefore, the offset of the position of the connecting hole 11 can be roughly determined by the offset of the light spot on the receiving plate 241.
[0018] In this embodiment, the lower end of the positioning block 23 is provided with a horizontally arranged cross plate, and each end of the cross plate is fixedly provided with a mounting block 26; the mounting block 26 is attached to the side of the platform 10. A pressure sensor is provided on the side of the mounting block 26 closest to the platform 10; when the pressure sensor contacts the side wall of the platform 10, there is a gap between the positioning block 23 and the side wall of the platform 10. Specifically, the force between the mounting blocks 26 at both ends of the cross plate and the side of the platform 10 can be used to determine whether the cross plate is parallel to the side wall of the platform 10, that is, whether the connecting rod 22 is perpendicular to the side of the platform 10. When the difference between the values displayed by the pressure sensors on the two mounting blocks 26 is within a certain range, it can be determined that the connecting rod 22 is basically perpendicular to the side of the platform 10.
[0019] In this embodiment, a display screen 27 is provided on the side of the patch 26 away from the platform 10. The display screen 27 is used to display the values measured by the pressure sensor. Specifically, the pressure value of the pressure sensor can be directly displayed on the display screen 27, and then the worker can judge it by himself. Alternatively, a relevant program can be programmed to automatically compare the values of the two pressure sensors. When the error is within a certain range, an indicator light can be used to provide a prompt.
[0020] In this embodiment, the positioning block 23 has a sliding hole at its upper end, and the connecting rod 22 is slidably disposed in the sliding hole. The cross-sectional shape of the connecting rod 22 is square, and the sliding hole is a shape adapted to the connecting rod 22. A sleeve 28 is provided at the end of the connecting rod 22 away from the limiting post 21. The inner wall of the sleeve 28 is threaded, and a screw 29 is threadedly connected to the sleeve 28. The axial direction of the screw 29 is parallel to the length direction of the connecting rod 22. The end of the screw 29 closest to the platform 10 abuts against the positioning block 23. Specifically, a lever or knob can be provided at the end of the screw 29, and the positioning block 23 can be slowly moved by rotating the screw 29 to achieve precise positioning.
[0021] In this embodiment, a scale is provided on the outer wall of the connecting rod 22, and the scale is distributed along the length of the connecting rod 22. Specifically, the scale can be read by the position of the positioning block 23, thereby obtaining the distance between the connecting hole 11 and the side of the platform 10.
[0022] In this embodiment, the upper end of the limiting post 21 is provided with a limiting piece 210, and the upper end of the limiting piece 210 is provided with a rotating shaft 211. A collar 212 is rotatably provided on the outer wall of the rotating shaft 211. The limiting piece 210 is attached to the upper surface of the platform 10, the axis of the rotating shaft 211 coincides with the axis of the limiting post 21, and the collar 212 is fixedly connected to the connecting rod 22. Specifically, the outer diameter of the limiting post 21 is slightly smaller than the inner diameter of the connecting hole 11, so that the limiting post 21 can be easily and quickly inserted into the connecting hole 11, but the gap between the limiting post 21 and the connecting hole 11 is small, and the shaking is also small.
[0023] In summary, the verification device for bolt connection holes on the extra-large installation platform surface in this embodiment involves inserting the limiting post 21 into the pre-drilled connection hole 11, then rotating the connecting rod 22 so that the positioning block 23 is attached to the side of the platform 10, and making the connecting rod 22 perpendicular to the side of the platform 10. After simultaneously inserting the limiting post 21 into both connection holes 11 and ensuring that both positioning blocks 23 are fully attached to the side wall of the platform 10, the distance measuring device 24 can be used to measure the precise distance between two adjacent positioning blocks 23. This allows for the measurement of the distance between two adjacent connection holes 11, which can be compared with the pre-designed distance to calculate whether the error is within the allowable range. The first limiting post 21 is then removed from the connection hole 11 and inserted into the second connection hole 11 to continue the subsequent connection hole 11 measurement operation. This method is relatively simple to operate and does not require highly skilled or precise operators to obtain accurate values quickly and efficiently. It can efficiently verify the drilling accuracy of the connection hole 11.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
