A roof anti-fall anchor device made of aluminum alloy

Abstract

The present invention discloses a roof anti-fall anchor device made of aluminum alloy, which relates to the field of anti-fall technology and includes a limit assembly, an anchor assembly, an anchor assembly, a positioning assembly, a steel cable, and a hook assembly. When the hook bracket on the hook assembly is close to the anchor ring, the hook bracket is first manually lifted so that the hook bracket first enters the first limit frame and the second limit frame, and then the upper end of the contact sensor contacts the inner surface of the first limit frame. At this time, the safety personnel controls the anti-slip electric push rod to drive the locking bracket to lift, thereby realizing a temporary locking function. When the locking bracket is lifted, the locking bracket drives the anti-slip block and the anti-slip magnet to slide downward through the linkage belt, so that the hook baffle is disengaged from the anti-slip magnet, and then the hook baffle is manually opened outward to open the notch on the hook bracket. At this time, the hook bracket can pass through the outer periphery of the anchor ring along the inner surface of the first limit frame and the second limit frame to realize a safe switching function.

Description

Technical Field

[0001] The present invention relates to the technical field of roof anti-falling, and in particular to a roof anti-falling anchoring device made of aluminum alloy. Background Art

[0002] During the decoration and construction of buildings, corresponding anti-fall anchor devices are generally installed for the safety of workers. These anti-fall anchor devices generally fix steel cables to the wall through anchor points, and then hang corresponding safety ropes on the steel cables to prevent workers from falling.

[0003] When existing anti-fall anchor devices pass through the anchor point, the hook at the upper end of the safety rope must be unhooked before passing through the anchor point. During this process, the safety rope is temporarily ineffective, greatly increasing the probability of safety accidents. Furthermore, existing anti-fall anchor devices lack corresponding locking measures when the hook opening cannot be closed or is damaged, thus failing to prevent safety accidents. Therefore, there is a need for an aluminum alloy roof anti-fall anchor device that can pass through the anchor point without ineffectiveness of the safety rope and can automatically lock with the steel cable when the hook opening is damaged, to address the shortcomings of existing anti-fall anchor devices.

[0004] For example, the patent with announcement number CN111911512B provides an anchoring device, which includes a lower part and an upper part. In a first position, the upper part can rotate freely relative to the lower part, and in a second position, the upper part acts on the bolt in a torque-transmitting manner. This application can effectively avoid the corresponding loosening problem when a force with a lateral force component is applied to the upper part. This solution still uses conventional bolts to fix to the wall, and when subjected to long-term vibration, it will still cause the bolts to loosen from the wall; this solution cannot solve the problem of the safety rope hook failing when it passes through the anchoring device; this solution cannot automatically lock the failed hook with the steel cable when the safety rope hook is damaged; and this solution cannot issue a warning signal when the safety rope hook is about to be unhooked.

[0041] Taking the preferred embodiment as an example, during the installation of the anchor assembly 3, the anchor screw 307 is first screwed into the positioning sleeve 404 of the positioning assembly 4. When the anchor screw 307 is tightened, the first gasket 304 and the second gasket 305 will be aligned with the first positioning hole 402 and the second positioning hole 403 respectively. At the same time, the positioning hole 315 on the anchor screw 307 will also be aligned with the positioning groove 405 on the positioning sleeve 404. Then the anchor assembly 2 is put on the outside of the positioning assembly 301; during the installation of the anchor assembly 2, the anchor support 203 is manually aligned with the anchor support 302, and the linkage sleeve 204 is inserted into the outside of the positioning assembly 301.

Then, the limiting ring 103 on the limiting assembly 1 is aligned with the first gasket 304, and the limiting ring 103, the first gasket 304 and the anchor bracket 306 are fixed together by bolts. The fixed bracket 306 is fixed to the wall 401 to realize the fixing function of the limit component 1; then the steel cable 5 is passed through the anchor ring 201 to realize the installation of the steel cable 5; when the hook bracket 601 on the hook component 6 is close to the anchor ring 201, the hook bracket 601 is manually lifted up first, so that the hook bracket 601 first enters the first limit frame 101 and the second limit frame 102, and then the upper end of the contact sensor 604 will first contact the inner surface of the first limit frame 101 and send a signal to the security personnel. At this time, the security personnel remotely controls the anti-slip electric push rod 611 to drive the locking bracket 602 to lift, so that the locking bracket 602 and the hook bracket 601 clamp the steel cable 5 to realize the temporary locking function and the hanging The limiting function of the hook bracket 601; when the locking bracket 602 is lifted, the locking bracket 602 drives the anti-dropping block 606 and the anti-dropping magnet 608 to slide downward through the linkage belt 616, so that the hook baffle 605 is out of contact with the anti-dropping magnet 608, and then the hook baffle 605 is manually opened outward to open the gap on the hook bracket 601, and then the anti-dropping block 606 is manually pressed down and the contact sensor 604 is in contact with the first limit frame 101, and then the anti-dropping electric push rod 611 is controlled to drive the locking bracket 602 to retract, and at this time the hook bracket 601 can pass through the outer side of the anchor ring 201 along the inner surface of the first limit frame 101 and the second limit frame 102 to realize the safety switching function;When the contact sensor 604 is no longer in contact with the first limit frame 101, and the hook baffle 605 loses contact with the pressure sensor at the rear end of the hook bracket 601, the pressure sensor controls the warning light 603 to immediately sound an alarm.

At this time, the staff checks whether the hook assembly 6 is abnormal. If the hook assembly 6 is normal or has just passed the anchor ring 201, the staff manually releases the anti-slip block 606, causing the spring in the anti-slip slide 610 to drive the anti-slip support 609 and the anti-slip block 606 to rebound.
