Description

Technical Field

[0001] The utility model belongs to the field of building construction, and particularly relates to a movable safety belt hanging device on a steel beam. Background Technique

[0002] In the operation of steel structure construction, many operations involve working at heights. To prevent accidental falling injuries, it is required that operators must wear safety belts. The safety belt mainly consists of a safety rope, a buffer, and a lacing. When in use, the metal buckle at the upper end of the safety rope is hung on the hanging point device on a fixed structure. Once a fall occurs, the hanging point device catches the safety rope to prevent further falling, thus providing safety protection for the operator. In steel structure construction, there are a large number of operations at heights. However, since the steel structure does not allow the installation of hanging point devices by welding or bolting, the end of the safety rope has to be tied to adjacent structural members. Since it is generally operated by non-lifting professionals, it is difficult to achieve standard and firm tying. Once a fall occurs, under the impact of gravity, the safety rope is very likely to fall off, unable to ensure safety and reliability. And when there are no other members available for utilization around, the safety rope has to be tied to the member under the feet, adopting the low-hanging method that poses the greatest threat to the human body, which further increases the danger; in addition, the fixed hanging point limits the working range and requires frequent replacement of the hanging point position, which is very inconvenient and greatly affects the work efficiency and construction progress; at the same time, the probability of safety risks also increases during the continuous replacement of the hanging point. Therefore, a movable safety belt hanging device on a steel beam has been developed. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a movable safety belt hanging device on a steel beam to solve the problems pointed out in the above background technique.

[0004] In order to achieve the above utility model purpose, the following technical solutions are further adopted:

[0005] A movable safety belt hanging device on a steel beam includes a supporting vertical plate. On both sides of the upper end of the supporting vertical plate, ear plates are symmetrically fixed. The lower end of the supporting vertical plate is fixedly connected to the middle of a horizontal supporting shaft. Rotating shafts are symmetrically installed on the horizontal supporting shaft. Fixing components are symmetrically installed at both ends of the horizontal supporting shaft, and at least one of the two fixing components is detachably connected to the horizontal supporting shaft. The fixing component includes a fixing vertical plate. A first fastening plate and a second fastening plate are vertically fixed on the fixing vertical plate. The second fastening plate is located below the first fastening plate. A plurality of fastening bolts are threadedly connected to the second fastening plate. After the upper end of the fastening bolt passes through the second fastening plate, a top pressing plate is fixed. The setting of the top pressing plate can increase the contact area with the upper flange plate of the steel beam, so that the safety belt hanging device can be more firmly fixed on the steel beam.

[0006] As a further improvement of the utility model, the lower end of the first fastening plate is flush with the lower end of the rotating shaft.

[0007] As a further improvement of the utility model, the pressing plate is a circular plate.

[0008] As a further improvement of the utility model, a circular operating handle for convenient rotation is fixed at the lower end of the fastening bolt.

[0009] As a further improvement of the utility model, a through hole is provided in the middle of the circular operating handle to facilitate inserting a wrench into the through hole to rotate the fastening bolt conveniently.

[0010] As a further improvement of the utility model, one end of the horizontal support shaft is fixedly connected to the fixing component, and the other end is detachably connected to the fixing component through a connecting piece.

[0011] As a further improvement of the utility model, the connecting piece includes a connecting screw rod fixed at the end of the other end of the horizontal support shaft. The connecting screw rod passes through the fixing vertical plate of the corresponding side fixing component and is threadedly connected with a fastening nut.

[0012] The beneficial effects of the utility model are as follows: Using the utility model as a safety rope hanging point does not damage the steel structure, the installation is firm and reliable, fully meeting the requirements of the load falling impact load, and ensuring the safety of high-altitude operators. Through the setting of the rotating shaft, the safety belt suspension device can be pushed or pulled to move on the steel beam, expanding the working surface, greatly improving the construction efficiency, and accelerating the construction progress. The utility model has a low manufacturing cost, can be recycled, is convenient for installation and disassembly, has obvious economic benefits, and saves labor, effort and time. When in use, the steel wire rope is tied to the ear plate at the upper end of the support vertical plate, and then the safety belt is hung on the steel wire rope. BRIEF DESCRIPTION OF THE DRAWINGS
