Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, and in particular to a portable on-site video acquisition device for building engineering management. Background Technology

[0002] In the field of construction project management, on-site video capture is crucial for controlling construction progress, supervising construction safety, and ensuring project quality. However, traditional on-site video capture equipment has many problems in practical applications.

[0003] Early fixed cameras, once their positions were determined, were difficult to change and could not be flexibly adjusted in terms of shooting angle. For large and complex construction sites, the monitoring range was extremely limited, with many blind spots, making it difficult to fully capture key information during the construction process. While some movable cameras could be adjusted to a certain extent, they often required frequent manual operation, which was extremely inconvenient and inefficient in the case of complex terrain and limited space at construction sites.

[0004] Most existing portable video acquisition devices require additional supports or complex manual adjustment devices for height adjustment. This not only makes the adjustment process cumbersome but also makes it difficult to accurately position the required height. It cannot meet the needs of quickly and flexibly adjusting the shooting height in different construction scenarios. When stored, they are bulky and complex in structure, making them inconvenient to carry and increasing the burden on engineering management personnel when moving around the construction site.

[0005] When faced with columnar structures commonly found on construction sites (such as tower crane columns and building support columns), installing video capture equipment at the required height usually requires operators to climb and fix it in place. This operation is not only cumbersome, but also inconvenient to adjust the height according to actual needs after installation. It is impossible to capture video at different column heights, which greatly limits the monitoring of the vertical construction of the building project.

[0006] Therefore, this utility model proposes a portable on-site video acquisition device for construction engineering management to solve the above problems.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0033] Reference Figure 1-6 A portable on-site video acquisition device for construction engineering management includes a housing 1, a lifting plate 11, a spherical camera 2, an arc-shaped frame 42, a mounting block 5, two fixing blocks 4, and a fixed camera 3. The lifting plate 11 is slidably installed inside the housing 1, and the bottom of the housing 1 is open. A mounting base is fixedly installed on the bottom side of the lifting plate 11, and the spherical camera 2 is fixedly installed on the bottom side of the mounting base. Three threaded sleeves are fixedly installed on the lifting plate 11. Three lead screws 12 are rotatably installed on the top inner wall and bottom inner wall of the housing 1, and the three lead screws 12 are threadedly connected to the corresponding threaded sleeves. Each lead screw 12 is fixedly fitted with a driven gear 15. An adjustment motor 13 is fixedly installed on the top inner wall of the housing 1. An active gear 14 is fixedly fitted on the output shaft of the adjustment motor 13. The active gear 14 meshes with the three driven gears 15, which can control the lifting plate 11 to rise and fall when the lead screw 12 rotates. This allows the spherical camera 2 to be retracted and extended from the opening at the bottom of the housing 1. A support plate is fixedly installed on the inner side wall of the housing 1, and the fixed camera 3 is fixedly installed on the support plate. The housing 1 has an installation opening, and the fixed camera 3 is adapted to the installation opening.

[0034] Mounting block 5 and two fixing blocks 4 are fixedly mounted on the outside of housing 1. A U-shaped rod 41 is fixedly mounted on each of the two fixing blocks 4. An arc-shaped frame 42 is slidably mounted on the U-shaped rod 41. Tension springs 43 are fixedly mounted on each of the two fixing blocks 4. Both tension springs 43 are fixedly connected to the arc-shaped frame 42, and both tension springs 43 are movably sleeved on the outside of the U-shaped rod 41, allowing the arc-shaped frame 42 to move closer to housing 1 when not being operated. Four rotating pins are rotatably mounted on the arc-shaped frame 42, and guide wheels 421 are fixedly sleeved on each of the four rotating pins, allowing the arc-shaped frame 42 to be controlled to move closer to housing 1 when subjected to loads. When the tension spring 43 is pulled, the arc frame 42 and guide wheel 421 are controlled to approach the column to be climbed, and can provide support and guidance for the housing 1 as it moves along the axis of the column. A mounting frame 51 is hinged on the mounting block 5, and two drive wheels 52 are rotatably mounted on the mounting frame 51. The two drive wheels 52 are symmetrically arranged based on the mounting block 5 as the center. A brake motor 53 is fixedly mounted on the mounting frame 51. The output shaft of the brake motor 53 is axially fixedly connected to one of the drive wheels 52, which enables the device to climb along the outside of the column and stop and stay in the position after climbing to a suitable height.

[0035] In this embodiment, in order to facilitate manual operation of the arc frame 42, make the device easy to carry, and facilitate the closure of the opening at the bottom of the housing 1 after the spherical camera 2 is stored inside the housing 1, and also provide support for the device when it is idle and placed on a table, a handle is fixedly installed on the arc frame 42, a handle is fixedly installed on the top of the housing 1, a protective cover 101 is threadedly installed on the bottom of the housing 1, and a support ring is fixedly installed on the bottom side of the protective cover 101.

[0036] In this embodiment, in order to facilitate image recording by the fixed camera 3 and avoid the external environment from affecting the normal operation of the fixed camera 3, a transparent cover is fixedly installed on the outside of the housing 1, and the transparent cover is adapted to the mounting opening.

[0037] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0038] Working principle: In use, first carry the device to the desired location using the handle, then pull the arc frame 42 with the handle to create distance between it and the housing 1. Next, place the multiple guide wheels 421 on the arc frame 42 and the two drive wheels 52 on the mounting frame 51 onto the outside of the column to be installed. Then release the handle. Under the reaction force of the tension spring 43, the multiple guide wheels 421 and the two drive wheels 52 can be controlled to abut against the outside of the column. Then unscrew the protective cover 101 of the device, and start the brake motor 53 after connecting the power. The output shaft of the brake motor 53 drives one of the drive wheels 52 to rotate. With the cooperation of the other drive wheel 52 and multiple guide wheels 421, the one drive wheel 52 drives the mounting frame 51, the arc frame 42 and the housing 1 to move synchronously upward along the column to the desired height and then stop. Since the brake motor 53 provides the drive for the drive wheel 52, it can still maintain good stability after stopping and will not move downward along the column due to its own weight or other factors.

[0039] Then start the adjustment motor 13. The output shaft of the adjustment motor 13 drives the drive gear 14 to rotate. The drive gear 14 drives the three driven gears 15 to rotate. The three driven gears 15 drive the three lead screws 12 to rotate respectively. The three lead screws 12 control the lifting plate 11 to move downward to a suitable position with the cooperation of the three screw sleeves, so that the spherical camera 2 can be extended from the opening at the bottom of the housing 1 and reach a suitable height.

[0040] Then, video can be captured from the scene using a fixed camera 3 and a spherical camera 2.
