Description

Technical Field

[0001] The utility model relates to the field of safety rope operations, in particular to a safety rope hanging buckle dedicated to H-shaped steel columns. Background Art

[0002] When installing H-shaped steel steel structures, there are only columns at the bottom of the H-shaped steel. Especially when there is no cross beam, during construction operations, workers rely only on ladders, and the ladders lean on the columns. However, the ladders are not sufficient to ensure the safety of construction workers. If safety wearing devices are used, it can provide an additional guarantee for construction workers. The new problem is that there is no safety rope hanging buckle that can be fixed on the H-shaped steel to hang the safety rope connected to the safety wearing device, and thus the problem of high hanging and low using of the safety belt cannot be solved.

[0003] Therefore, it is necessary to design a safety rope hanging buckle with quick installation and disassembly to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a safety rope hanging buckle applicable to H-shaped steel.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A safety rope hanging buckle dedicated to H-shaped steel columns includes an outer fixing plate, an eccentric shaft, a locking component, and a movable safety bending plate fixed to the eccentric shaft;

[0007] One end of the outer fixing plate is in a hook shape and is used to surround one end of the H-shaped steel wing plate in the width direction. The outer fixing plate is located outside the wing plate, and the other end of the wing plate is located between the movable safety bending plate and the other end of the outer fixing plate;

[0008] The eccentric shaft includes a rotating shaft and an eccentric locking shaft that rotates eccentrically relative to the rotating shaft;

[0009] Wherein, one end of the rotating shaft freely passes through the outer fixing plate and is rotatably connected to the outer fixing plate, and the other end of the rotating shaft is fixed to the eccentric locking shaft;

[0010] The locking component is used to keep the position of the eccentric shaft relative to the outer fixing plate unchanged in the thickness direction of the wing plate;

[0011] The movable safety bending plate is integrally bent and includes an operation plate and a friction plate that are respectively parallel to the wing plate. The intersection of the operation plate and the friction plate rotates coaxially with the rotating shaft;

[0012] Wherein, a safety rope lock hole is provided at the tip of the operation plate located outside the H-shaped steel;

[0013] When the operation panel tilts upward from the initial position, there is a gap between the wing plate and the eccentric locking shaft, and the tip of the friction plate leaves the other end of the wing plate. The eccentric shaft can move vertically.

[0014] When the operation panel is pressed down, the eccentric locking shaft rotates eccentrically relative to the rotating shaft, causing the gap between the wing plate and the eccentric locking shaft to gradually disappear. The eccentric shaft presses the wing plate and the friction plate fits against the other end of the wing plate.

[0015] Further, the locking member includes a gasket and a nut. One end of the rotating shaft is provided with a thread that mates with the nut. The gasket is sleeved outside one end of the rotating shaft, and the nut locks the position of the rotating shaft relative to the outer fixing plate.

[0016] Further, the number of safety rope hanging buckles is two.

[0017] Further, the outer fixing plate is provided with weight-reducing holes.

[0018] In the above technical solution, the present utility model has the following beneficial effects:

[0019] During the work at height of the H-shaped steel member, the safety rope hanging buckle can be fixed at any height position of the H-shaped steel, effectively ensuring the safety of construction workers.

[0020] When in use, first hang the hooked end of the outer fixing plate on one side of the width of the wing plate of the H-shaped steel, then press down the operation panel of the movable safety bent plate, so that the eccentric locking shaft is fastened to the end face at the other end in the width direction of the wing plate. At the same time, the friction plate of the movable safety bent plate fits against the wing plate, restricting the safety rope hanging buckle from falling off in the thickness direction of the wing plate; when it needs to be moved, the operation panel of the movable safety bent plate can be lifted upward to release the fastening of the eccentric locking shaft, and at the same time the friction plate also disengages from the wing plate, and the safety rope hanging buckle can be removed from the side and moved to the next position of the H-shaped steel column.

[0021] The special safety rope hanging buckle can be quickly installed and disassembled, which is convenient and safe; it improves work efficiency and reduces safety investment. In this way, the safety wearing device can be hung on the H-shaped steel through the safety rope hanging buckle. Even if the ladder loses weight and tilts, the safety wearing device can hold the operator. In addition, in order to be suitable for climbing operations, when changing the position of the operator, the two safety rope hanging buckles can be used alternately. Description of the Drawings

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0030] It should be noted that the orientation or positional relationship indicated by the terms "above", "one end", "upper", etc. used in this article is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description. Similar expressions are only for the purpose of illustration and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] Such as Figures 1-4 shown, a safety rope hanging buckle dedicated to an H-shaped steel column includes an outer fixing plate 1, an eccentric shaft 2, a locking component, and a movable safety bending plate 3 fixed to the eccentric shaft 2.

[0032] The H-shaped steel includes two oppositely arranged flange plates and a web connecting the two flange plates, and a safety rope hanging buckle is installed on any one of the flange plates.

[0033] One end of the outer fixing plate is hook-shaped and is used to surround one end in the width direction of the flange plate of the H-shaped steel. The outer fixing plate is located outside the flange plate, and the other end of the outer fixing plate is flat and exceeds the width of the flange plate to provide an installation basis for the eccentric shaft 2. Preferably, the vertical dimension of the hook-shaped end of the outer fixing plate is greater than the vertical dimension of its other end.

[0034] The other end of the wing plate is located between the other ends of the movable safety bending plate and the outer fixing plate.

[0035] The eccentric shaft 2 includes a fixed eccentric locking shaft 21 and a rotating shaft 22. The eccentric locking shaft 21 can rotate eccentrically relative to the rotating shaft 22. The axis of rotation of the eccentric locking shaft 21 and the axis of rotation of the rotating shaft 22 are coaxial, but the geometric axis where the center of the eccentric locking shaft 21 is located has a distance from its own axis of rotation.

[0036] One end of the rotating shaft 22 freely passes through the outer fixing plate 1 and is rotatably connected to the outer fixing plate 1. The other end of the rotating shaft 22 is fixed to the eccentric locking shaft 21. The two axial end faces of the eccentric locking shaft 21 abut between the movable safety bending plate 3 and the outer fixing plate.

[0037] The locking member is arranged on the outer fixing plate 1 to keep the position of the eccentric shaft relative to the outer fixing plate unchanged in the thickness direction of the wing plate, so as to realize the synchronous up and down movement of the eccentric locking shaft 21 and the outer fixing plate 1. The rotating shaft only rotates relative to the outer fixing plate 1, but there is no position movement in the thickness direction of the wing plate.

[0038] The movable safety bending plate 3 is integrally bent and includes an operation plate 31 and a friction plate 32. At the intersection of the operation plate 31 and the friction plate 32, that is, the root of the two rotates coaxially with the rotating shaft 22.

[0039] Among them, a safety rope lock hole 311 is formed at the tip of the operation plate 31 located outside the H-shaped steel.

[0040] When the operation plate 31 tilts upward from the initial position, there is a gap between the wing plate and the eccentric locking shaft 21 and the tip of the friction plate leaves the wing plate, and the eccentric shaft 2 can move vertically.

[0041] When the operation plate 31 is pressed down, the eccentric locking shaft 21 makes an eccentric movement relative to the movable safety bending plate 3 and the rotating shaft. The gap between the wing plate and the eccentric locking shaft 21 gradually disappears. The eccentric shaft 2 presses the wing plate and the friction plate 32 fits the other end of the wing plate, so that the friction force between the other end of the wing plate and the friction plate becomes larger.

[0042] Preferably, the locking member includes a gasket 41 and a nut 42. One end of the rotating shaft 22 is provided with a thread for mating with the nut 42. The gasket 41 is sleeved outside one end of the rotating shaft 22, and the nut 42 locks the position of the rotating shaft 22 relative to the outer fixing plate 1. Both the gasket 41 and the nut 42 are located on the outer surface of the outer fixing plate 31. When the operation plate 31 is pressed down, since the eccentric locking shaft 21 presses the wing plate, the wing plate abuts against one end of the outer fixing plate. At the same time, the greater the downward pressing force of the operation plate 31, the vertical displacement of the eccentric shaft 2 and the wing plate is fixed; since one end of the outer fixing plate is in a hook shape, the position of one end of the wing plate in the thickness direction of the wing plate can be fixed, and the other end of the wing plate is in close contact with the friction plate 32, further fixing the position of the eccentric shaft 2 and the wing plate in the thickness direction of the wing plate.

[0043] Preferably, the number of safety rope hanging buckles is two. To be applicable to the climbing scenario, the two safety rope hanging buckles are used alternately. When the operator goes up and down, the position of the first safety rope hanging buckle on the wing plate is fixed, and the position of the other safety rope hanging buckle on the wing plate is changed and fixed to facilitate the operator to move to the other safety rope hanging buckle; after the operator moves to the other safety rope hanging buckle, the position of the first safety rope hanging buckle on the wing plate is moved again.

[0044] Preferably, when the operation plate 31 is tilted upward from the initial position, the operation plate 31 is located outside the H-shaped steel and forms an angle of 30 degrees with the horizontal direction, and the friction plate 32 forms an angle of 120 degrees with the operation plate 31. When the operation plate 31 is tilted downward until the eccentric locking shaft 21 abuts against the end face of the wing plate, the distance from the bottom edge of the eccentric locking shaft 21 to the axis of the eccentric locking shaft 21 is the largest, that is, the grounding distance of the outer surface of the eccentric locking shaft 21 is the smallest.

[0045] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
