Description

Technical Field

[0001] This utility model relates to the field of fall arrestor suspension technology, and more specifically, to an aluminum alloy casement window auxiliary fall arrestor suspension. Background Technology

[0002] Casement windows are a type of window used in residential buildings, where the sash moves horizontally when opened and closed. Casement windows are divided into sliding and top-hung types. Their advantages include a large opening area, good ventilation, good sealing, and excellent sound insulation, heat insulation, and water resistance. Aluminum alloy casement windows are window products made of aluminum alloy profiles for both the outer frame and sash frame, achieving ventilation by opening inwards or outwards. When installing aluminum alloy casement windows, cranes or other equipment are needed to hoist the window frame from the ground. However, there are no protective measures outside the hoisting opening, posing a risk of fall for workers standing in the hoisting opening, and the hoisted window frame itself may also fall. Therefore, we have proposed an auxiliary anti-fall suspension device for aluminum alloy casement windows. Utility Model Content

A hanging device of a certain length is provided to prevent workers from falling through window openings. A support mechanism 9 is provided on the side of the height adjustment mechanism 2. The height adjustment mechanism 2 includes a lower branch pipe 10 fixedly connected to the top surface of the lower support plate 1 and a manual hydraulic cylinder 11 fixedly installed on the top surface of the lower support plate 1. The manual hydraulic cylinder 11 is located inside the lower branch pipe 10. An operating groove 18 is provided on the side of the lower branch pipe 10. A lifting column 12 is fixedly connected to the top of the manual hydraulic cylinder 11. A lifting pipe 13 is movably sleeved on the outer side of the top of the lifting column 12. The top of the lifting pipe 13 is connected to the bottom surface of the upper support plate 14. Multiple first through holes 15 are provided on the lifting column 12. The lifting pipe 13 has multiple through holes 15 on both sides. Each has a first fixing hole 16, and a first bolt assembly 17 is fitted into the inner cavity of the first fixing hole 16. The first bolt assembly 17 passes through the inner cavity of a first through hole 15. The cantilever mechanism 3 includes a cantilever pipe 19 fixedly connected to the side of the lifting pipe 13. A cantilever column 20 is movably sleeved in the inner cavity of the cantilever pipe 19. The end of the cantilever column 20 extends to the outside of the cantilever pipe 19 and is connected to the hoisting seat 4. Multiple second through holes 22 are opened on the side of the cantilever column 20. Second fixing holes 21 are opened on both sides of the cantilever pipe 19.

Through the threaded engagement between the stud 27 and the threaded hole 26, the top of the conical head 28 abuts against the connection between the lifting seat 4 and the cantilever column 20, so that the support mechanism 9 can support the cantilever mechanism 3.

[0019] Example 2: Based on Example 1, such as Figures 1 to 4As shown, the sides of the lifting column 12 are respectively fitted with the inner walls of the lower branch pipe 10 and the lifting pipe 13 to ensure the stability of the lifting column 12 during expansion and contraction within the lower branch pipe 10 and the lifting pipe 13. The outer diameter of the first bolt assembly 17 is equal to the inner diameter of the first through hole 15 and the first fixing hole 16 to ensure the stability of the first bolt assembly 17 when inserted into the inner cavities of the first through hole 15 and the first fixing hole 16, thereby ensuring the stability of the connection between the lifting column 12 and the lifting pipe 13. The side of the cantilever column 20 is fitted with the inner wall of the cantilever pipe 19 to ensure the stability of the cantilever column 20 during expansion and contraction within the cantilever pipe 19. The outer diameter of the second bolt assembly 23 is... The inner diameters of the second bolt assembly 23 and the second fixing hole 21 and the second through hole 22 are not equal to ensure the stability of the second bolt assembly 23 when inserted into the inner cavity of the second fixing hole 21 and the second through hole 22, thereby ensuring the stability of the connection between the cantilever pipe 19 and the cantilever column 20. In addition, the first bolt assembly 17 and the second bolt assembly 23 are both composed of hexagonal socket head cap screws, nuts and washers. This is a conventional mechanism. The two sides of the lower support plate 1, the lower branch pipe 10, the lifting pipe 13 and the upper support plate 14 are all flush, ensuring that the sides of the lower support plate 1, the lower branch pipe 10, the lifting pipe 13 and the upper support plate 14 can contact the wall surface so that the wall surface can provide support.

[0020] It should be noted that this utility model is an auxiliary anti-fall suspension device for aluminum alloy casement windows. In use, firstly, the lifting tube 13 is extended or retracted at the top of the lifting column 12, so that the bottom surface of the lower support plate 1 contacts the ground. Simultaneously, the upper support plate 14 at the top of the lifting tube 13 is brought close to the roof, and the two first fixing holes 16 on the side of the lifting tube 13 are aligned with the two first through holes 15 on the lifting column 12. First bolt assemblies 17 are inserted into the first through holes 15 and the first fixing holes 16, thereby fixing the lifting column 12 and the lifting tube 13 together. Then, the lifting tube 13 and the upper support plate... The side of 14 contacts the top beam around the window opening, and the manual hydraulic cylinder 11 is manually driven to move the lifting column 12, lifting pipe 13 and upper support plate 14 upward, so that the top surface of the upper support plate 14 contacts the roof. In addition, the cantilever column 20 and the hoisting seat 4 are pulled outward, so that the first hanger 6 and the second hanger 8 under the hoisting seat 4 are placed on the side of the window opening. At this time, the two second fixing holes 21 on the side of the cantilever pipe 19 are aligned with the second through holes 22 on the cantilever column 20. The second bolt assembly 23 is inserted into the second fixing holes 21 and the second through holes 22 for fixing, and then... Turn the second bolt assembly 23 so that the tip of the conical head 28 aligns with the connection between the lifting base 4 and the cantilever column 20. Hold the rotating column 29 and rotate the stud 27. The threaded engagement between the stud 27 and the threaded hole 26 causes the stud 27 and the conical head 28 to move upwards, so that the tip of the conical head 28 rests against the connection between the lifting base 4 and the cantilever column 20. This utilizes the rotating base 24, the support column 25, the stud 27, and the conical head 28 to support the cantilever mechanism 3 and the lifting base 4. Finally, the hook at the bottom of the second suspension device 8 is connected to the worker's safety belt via a rope. When the worker... When a worker falls through the window opening, the locking device inside the second hanger 8 locks the rope to prevent the worker from falling. Additionally, when hoisting the window, workers use hoisting ropes to pull the hook below the first hanger 6 towards the ground, causing the rope in the first hanger 6 to slowly extend and connect the hook below the rope to the hoisted window. As the window rises, the rope on the first hanger 6 gradually contracts. When the hoisted window experiences a rapid fall, the locking device inside the first hanger 6 locks the rope to prevent the window from falling.
