Description

Technical Field

[0001] The utility model belongs to the field of building construction equipment, and in particular relates to a movable safety belt hanging device for an H-shaped steel beam. Background Art

[0002] With the development of the construction industry, steel structures are increasingly used in various types of buildings. The main construction of steel structures includes the installation of steel columns and steel beams. When the steel beams are hoisted to the designated location for temporary connection, workers need to install steel beam bolts, weld steel beams, and remove steel beam decks and lifting lugs. Since lifelines are often not available in the early stages of steel beam construction, safety belts are usually hung on the steel beams to ensure the safety of workers. However, this practice makes it inconvenient for workers to move, and they need to untie the safety ropes when moving, which increases the risk of working at height.

[0003] In the past, many kinds of safety belt suspension devices have been disclosed in patents. For example, the utility model patent with the authorization announcement number CN205127200U discloses a movable steel beam safety belt suspension device: including a sliding sleeve that can slide on the I-beam, the sliding sleeve is formed by at least two groove-shaped folding plates, and the top edge of the groove-shaped folding plates is provided with a docking ring that is connected to each other; the top of the sliding sleeve is fixed with a clamp for fixing the safety belt. The utility model patent with the authorization announcement number CN218205854U discloses a steel beam assembled safety belt adjustable suspension device: a fixed clamp is fixedly installed at one end of the load-bearing crossbar, a sliding clamp is slidably installed on the load-bearing crossbar, a spring buckle used in conjunction with the clamping groove is installed on the sliding clamp, and a safety belt hanging device is movably installed on the load-bearing crossbar between the fixed clamp and the sliding clamp. The utility model patent with authorization announcement number CN219878970U also discloses a temporary suspension device for a construction safety belt: the suspension device is connected to the wing plate of the steel structure, the suspension device includes a pin shaft, two sets of clamping components are arranged on the pin shaft, anti-loosening fasteners are connected to both sides of the clamping components, rollers are arranged on the clamping components, and the rollers are clamped to the edge of the wing plate; a hanging plate is arranged in the middle position of the pin shaft, the hanging plate is provided with a connecting hole, and the hook of the safety belt is connected to the connecting hole.

[0004] However, the above-mentioned safety belt suspension device cannot be applied to H-beams with stiffening ribs and lifting lugs that have not been removed. In this case, workers need to first release the connection between the safety belt suspension device and the H-beam, and then pass over the stiffening ribs and lifting lugs in the H-beam before they can continue to use it. In this process, there are certain safety hazards because the safety belt suspension device is not temporarily connected to the H-beam. In addition, if the above-mentioned device is too tightly connected to the H-beam, the safety belt may be rigidly dragged during walking, causing serious wear of the paint on the surface of the H-beam, affecting the construction quality. Therefore, there is an urgent need to design a movable safety belt suspension device for H-beams. Utility Model Content

[0036] In the device of the present utility model, the first card slot 101 and the second card slot 103 are both C-shaped as a whole. The first card slot 101 and the second card slot 103 are respectively arranged on both sides of the upper flange 501 of the H-shaped steel beam 5, one end of which is located on the upper side of the upper surface of the upper flange 501, and the other end is located on the lower side of the lower surface of the upper flange 501.

[0038] like Figure 2 As shown, the first adjustment end 108 and the second adjustment end 109 are connected by an open body fixing member 107. In this embodiment, the open body fixing member 107 adopts two identical long strip plates, which are arranged in parallel on both sides of the first adjustment rod 102 and the second adjustment rod 104.

In this embodiment, the first ear plate 105 and the second ear plate 106 are respectively welded to one end of the first slot 101 and the second slot 103 located on the upper side of the upper flange 501. Under normal construction conditions, the worker's safety belt needs to be connected to the first ear plate 105 and the second ear plate 106 of the first suspension mechanism 1 and the second suspension mechanism 2 at the same time to ensure construction safety.

Figure 4 As shown, the first suspension mechanism 1 is moved across the lifting eye 503, moved to the other side and then connected to the H-beam 5. Then the safety belt suspension device is moved to make the second suspension mechanism 2 closer to the lifting eye 503, and then the connection between the second suspension mechanism 2 and the H-beam 5 is released, and the second suspension mechanism 2 is moved across the lifting eye 503, moved to the other side of the lifting eye 503 and then connected to the H-beam 5, so as to realize the movement of the safety belt suspension device on the H-beam 5, and at the same time ensure that the suspension mechanism is connected to the H-beam 5 at any time.

[0044] (2) When the safety belt suspension device is used on the H-beam 5, it is moved to one side of the stiffening plate 502, and the connection between the first suspension mechanism 1 closer to the stiffening plate 502 and the H-beam 5 is first released. The first suspension mechanism 1 is moved across the stiffening plate 502, moved to the other side of the stiffening plate 502, and then connected to the H-beam 5. The safety belt suspension device is then moved so that the second suspension mechanism 2 is closer to the stiffening plate 502, and then the connection between the second suspension mechanism 2 and the H-beam 5 is released. The second suspension mechanism 2 is moved across the stiffening plate 502, moved to the other side of the stiffening plate 502, and then connected to the H-beam 5, so as to realize the movement of the suspension device on the H-beam 5, and at the same time ensure that the suspension mechanism is connected to the H-beam 5 at any time.

Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
