Description

Technical Field

[0001] This utility model belongs to the technical field of safety protection devices, and in particular relates to a safety protection device for electromechanical installation engineering construction. Background Technology

[0002] Mechanical and electrical installation projects often involve high-altitude, live-line, and overlapping operations, resulting in high risks. Installing safety railings can prevent workers from falling and tools from dropping, isolate live equipment and operating machinery, avoid electric shock and mechanical injuries, delineate work areas, and reduce interference between different trades; simultaneously, it complies with safety regulations and is a crucial measure to ensure the safety of personnel and the project.

[0003] Existing safety railings have several drawbacks, such as: the height of the railings cannot be adjusted, making them unsuitable for diverse electromechanical installation scenarios. For example, high-altitude work platforms require railings of at least 1.2 meters, while temporary passageways only need 0.8 meters of warning. Fixed heights are either insufficiently protective or redundant. Furthermore, assembling two sets of railings requires tools, with each component needing to be secured individually. Large-scale assembly involves numerous tool-operated steps, making it more time-consuming than tool-free assembly and increasing labor costs. Therefore, we propose a safety protection device for electromechanical installation engineering construction. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for electromechanical installation engineering construction, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a construction safety protection device for electromechanical installation engineering, comprising two support columns, and further comprising: Two fixing bars are respectively inserted into two support columns. A fixing rod is fixedly installed between the two fixing bars. A sliding bar is slidably installed between the two fixing bars and above the fixing rod. A plurality of first fixing columns are installed on the top of the fixing rod. A first sliding column is slidably installed in each of the plurality of first fixing columns. The plurality of first sliding columns are all fixedly connected to the sliding bar. The second fixed column is fixedly installed on the top of the fixed rod. The second sliding column is slidably installed inside the second fixed column. The second sliding column is fixedly connected to the sliding strip. Both of the two support columns are provided with a power cavity. Two limiting rods are symmetrically rotated and installed in both power cavities. The limiting rods are inserted and engaged with the fixed strip. Two sets of drive components are located in two support columns respectively and are used to drive the rotation of eight limit rods; A fixing component is located inside the second sliding column and is used to fix the position of the second sliding column.

[0006] In this technical solution, when the overall device needs to be installed, the drive component can drive the four limit rods to rotate. After all four limit rods are fully inserted into the power cavity, the fixing strip is inserted into the support column. The drive component can then drive the four limit rods to rotate downwards, with two of the limit rods inserting into the fixing strip. This fixes the position of the fixing strip, making it convenient to combine and install the two devices. The operation is simple and requires no tools. When it is necessary to adjust the height of the first sliding column extending outward, the sliding bar can be pulled to slide by the fixed component. The sliding bar drives several first sliding columns to slide within several first fixed columns. When the position of the sliding bar is appropriate, the position of the second sliding column can be fixed by the fixed component, and the position of the sliding bar can be further fixed to ensure that the whole device can be used in various environments.

[0007] In the above technical solution, the driving component further includes: A rectangular bar is slidably installed inside the power chamber. Two racks are symmetrically fixedly installed on the rectangular bar. Gears are meshed on one side of each of the four racks. The four gears are fixedly connected to four limiting rods respectively. A threaded rod is threadedly installed at the upper end of the rectangular bar. The upper end of the threaded rod passes through the rectangular bar and the power chamber and extends to the outside. The threaded rod and the four gears are rotatably connected to the power chamber. The four racks are slidably connected to the power chamber.

[0008] In this technical solution, when the overall device needs to be installed, the threaded rod is first rotated forward. Under the action of the thread, the rectangular bar slides downward, which drives the four racks to slide downward. The four racks drive the four gears meshing with them to rotate, and the four gears drive the four limiting rods to rotate. When all four limiting rods are fully inserted into the power chamber, the fixing strip is inserted into the support column. Then, by reversing the above operation, the four limiting rods can be driven to rotate downward, and two of the limiting rods will be inserted into the fixing strip, which can fix the position of the fixing strip. This facilitates the combination and installation of the two devices, and the operation is simple and does not require the use of tools.

[0009] In the above technical solution, the fixing component further includes: A limiting groove is formed inside a second sliding column. A sliding rod is slidably installed inside the limiting groove. Two connecting rods are rotatably installed at the lower end of the sliding rod. A limiting block is rotatably installed at the lower end of each of the two connecting rods. Several grooves are formed on the second fixed column. The ends of the two limiting blocks that are far apart from each other pass through the limiting groove. The limiting blocks are inserted into the grooves. The upper end of the sliding rod passes through the limiting groove and extends to the outside. Both limiting blocks are slidably connected to the limiting groove. The handle is fixedly installed at the top of the sliding rod. Two guide posts are fixedly installed at the top of the sliding rod. The upper ends of the two guide posts pass through the handle. A tension spring is sleeved on each of the two guide posts. The handle is slidably connected to the two guide posts.

[0010] In this technical solution, when it is necessary to adjust the height of the first sliding column extending outward, first pull the handle upward. The handle pulls the two tension springs to extend, and at the same time, the handle drives the sliding rod upward. The sliding rod pulls the two connecting rods to rotate. The two connecting rods respectively pull the two limiting blocks to slide and move closer to each other. When both limiting blocks are fully inserted into the limiting groove, the sliding strip can be pulled to slide. The sliding strip drives several first sliding columns to slide in several first fixed columns. When the position of the sliding strip is appropriate, release the handle. Under the action of the tension of the two tension springs, the handle slides downward. The handle drives the sliding rod downward. The sliding rod squeezes the two connecting rods to rotate. The two connecting rods respectively squeeze the two limiting blocks to slide and move away from each other. The two limiting blocks are respectively inserted into the corresponding grooves, which can fix the position of the second sliding column. Furthermore, it can fix the position of the sliding strip, ensuring that the overall device can be used in various environments.

[0011] Furthermore, in the above technical solution, the second sliding column is engraved with scale lines.

[0012] In this technical solution, the slider is fixed in the appropriate position by observing the scale lines.

[0013] In the above technical solution, further, the grooves are evenly spaced on the second fixed post.

[0014] In this technical solution, the slider can be fixed at any height.

[0015] In the above technical solution, the cross-section of the fixing strip is T-shaped.

[0016] In this technical solution, it is ensured that the fixing strip will not shift after being inserted into the support column.

[0017] In the above technical solution, furthermore, the two ends of the tension spring are fixedly connected to the sliding bar and the handle, respectively.

[0018] In this technical solution, the tension spring is ensured to be used stably.

[0019] The beneficial effects of this utility model are: 1. The construction safety protection device for this electromechanical installation project, when the overall device needs to be installed, can drive four limit rods to rotate through the set drive component. After all four limit rods are fully inserted into the power cavity, the fixing strip is inserted into the support column.

Moreover, the operation is simple and does not require the use of tools.

[0020] 2. The construction safety protection device for this electromechanical installation project, when it is necessary to adjust the height of the first sliding column extending outward, can pull the sliding bar to slide through the set fixing components. The sliding bar drives several first sliding columns to slide within several first fixed columns respectively.
