Description

Technical Field

[0001] This utility model relates to the technical field of fall protection devices in building construction, specifically a fall protection device for building construction safety. Background Technology

[0002] Fall arresters effectively prevent workers from falling by securing the connection between the worker and the safety rope, thus ensuring their safety. In high-altitude operations, if a worker slips or other unexpected situation occurs, the fall arrester can be triggered immediately and take measures to avoid serious consequences. With fall arresters installed, workers can work at heights with greater peace of mind, avoiding negligence and anxiety caused by fear of falling, thereby improving work efficiency and quality.

[0003] For example, the construction safety fall protection device disclosed in the authorization announcement number CN219548447U includes two support rods, a fall protection net is fixedly installed between the two support rods, support straps are fixedly installed at the front and rear ends of the fall protection net, and the two ends of the support straps are fixedly connected to the support rods. A front clamping plate is fixedly installed at the front end of each of the two support rods, a rear clamping plate is correspondingly installed at the rear side of each of the two front clamping plates, a connecting column is fixedly installed on each of the two rear clamping plates, the front end of the connecting column is sleeved with a sliding sleeve that is snapped onto the front clamping plate, and a fixing nut is connected to the front end of the connecting column through a spiral thread.

[0004] Although it achieves the clamping of the side wall of the window through the front and rear clamps, and fixes the two support rods to both sides of the window, the two support rods can open the fall protection net outside the window for fall protection.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the construction fall protection device not only realizes the convenient movement of the construction fall protection device to the work area for protection, facilitates convenient extension and adjustment of protection, and increases the relative protection area, but also facilitates folding and moving the device together, and facilitates increasing the protection area after unfolding, thereby improving the protection effect of the construction fall protection device.

[0018] (1) When using the fall protection device for construction safety, open two sets of electric wheels. The electric wheels drive the rotating shaft to slide inside the track. The rotating shaft drives the support plate, support column, gimbal plate, extension plate, first extension plate, second extension plate, third extension plate, and fourth extension plate to move to the bottom of the work area. This facilitates convenient movement to the work area for protection and improves the convenience of moving the fall protection device.

[0019] (2) When it is necessary to extend the extension plate 4, two sets of stepper motors are turned on.

Under the threaded connection between the second threaded rod and the second threaded block, the second threaded rod drives the second threaded block to move. The second threaded block drives the extension plate to move, so that the two sets of extension plates can extend outward, which facilitates the extension of the extension plate 4 and realizes the convenient extension adjustment protection of the construction fall protection device, increasing the relative protection area.

[0020] (3) When the protective area needs to be expanded, the dual-axis motor is turned on. With the support of the support block, the dual-axis motor drives the first threaded rod to rotate. With the threaded connection between the first threaded rod and the first threaded block, the first threaded rod drives the first threaded block to move. The first threaded block drives the first arm and the second arm to move through two sets of support shafts respectively. With the support of the second hinge and the second T-shaped buckle, the first arm and the second arm extend in a cross manner. The first arm drives a set of sliding blocks to slide on the surface of the limit rod, and the second arm drives another set of sliding blocks to slide on the surface of the limit rod. The U-shaped block supports the limit rod through the first T-shaped buckle. Driven by the power of the first arm and the second arm, the fourth extension plate and the third extension plate are connected by the first hinge. The hinges rotate around the axis, with the second and third extension plates rotating around the second hinge, the first and second extension plates rotating around the third hinge, and the gimbal plate and the first extension plate rotating around the fourth hinge. This facilitates the unfolding of the first, second, third, and fourth extension plates. The dual-axis motor is opened in the reverse direction to facilitate folding the first, second, third, and fourth extension plates together. This convenient unfolding of the extension plates enables easy folding and unfolding of the construction fall protection device, facilitating movement when folded together, increasing the protective area after unfolding, and improving the protective effect of the construction fall protection device.

The electric wheels 11 are slidably connected to the track 2.

[0034] When using the fall protection device for construction safety, the two sets of electric wheels 11 are opened. The electric wheels 11 drive the rotating shaft 10 to slide inside the track 2. The rotating shaft 10 drives the support plate 1, support column 9, gimbal plate 3, extension plate 4, first extension plate 5, second extension plate 6, third extension plate 7, and fourth extension plate 8 to move to below the working area. This facilitates convenient movement to the working area for protection and improves the ease of movement of the construction fall protection device.

The side of the second arm 14 away from the limiting rod 12 is movably connected to another set of support shafts 25.

[0039] A second T-shaped buckle 32 is movably installed at the intersection of the first arm 13 and the second arm 14, and the second T-shaped buckle 32 is movably connected to the second hinge joint 19;

[0040] When the protected area needs to be expanded, the dual-axis motor 22 is turned on. Supported by the support block 21, the dual-axis motor 22 drives the first threaded rod 23 to rotate. With the threaded connection between the first threaded rod 23 and the first threaded block 24, the first threaded rod 23 drives the first threaded block 24 to move. The first threaded block 24, via two sets of support shafts 25, drives the first arm 13 and the second arm 14 to move respectively. Supported by the second hinge 19 and the second T-shaped buckle 32, the first arm 13 and the second arm 14 extend in a crisscross pattern. The first arm 13 drives a set of sliding blocks 17 to slide on the surface of the limiting rod 12, and the second arm 14 drives another set of sliding blocks 17 to slide on the surface of the limiting rod 12. The U-shaped block 15 supports the limiting rod 12 via the first T-shaped buckle 16. Driven by the power of the first arm 13 and the second arm 14, the fourth extension plate 8 and... The third extension plate 7 rotates around the first hinge 18, the second extension plate 6 and the third extension plate 7 rotate around the second hinge 19, the first extension plate 5 and the second extension plate 6 rotate around the third hinge 20, and the gimbal plate 3 and the first extension plate 5 rotate around the fourth hinge 26.

The dual-axis motor 22 is opened in the reverse direction to facilitate the folding of the first extension plate 5, the second extension plate 6, the third extension plate 7, and the fourth extension plate 8 together. This facilitates the convenient unfolding of the extension plates, enabling the construction fall protection device to be easily folded and unfolded. It also facilitates the movement of the folded plates, increases the protective area after unfolding, and improves the protective effect of the construction fall protection device.

[0041] Working principle: When using the fall protection device for construction safety, the two sets of electric wheels 11 are activated.

The stepper motor 29 drives the second threaded rod 30 to rotate. The second threaded rod 30 drives the second threaded block 31 to move. The second threaded block 31 drives the extension plate 4 to move, causing the two sets of extension plates 4 to extend outward. The dual-axis motor 22 drives the first threaded rod 23 to rotate. The first threaded rod 23 drives the first threaded block 24 to move. The first threaded block 24 drives the first arm 13 and the second arm 14 to move via the two sets of support shafts 25 respectively. The first arm 13 and the second arm 14 extend in a crisscross pattern. The first arm 13 drives a set of sliding blocks 17 to slide on the surface of the limiting rod 12, and the second arm 14 drives another set of sliding blocks 17 to slide on the surface of the limiting rod 12.
