Description

Technical Field

[0001] The invention relates to the field of safety belt fixing devices for construction projects, and more particularly to a safety belt fixing device for edge operations. Background Art

[0002] In engineering construction, working at height is one of the most dangerous parts. In order to ensure the safety of workers, safety protection is essential. Generally speaking, the safety measures taken for working at height include setting up guardrails, installing safety doors, setting up protective scaffolding, etc. In working at height, the edge of the working surface has no enclosure facilities or has enclosure facilities but the height is low. It is called edge working. Workers must wear safety belts to ensure the safety of workers.

[0003] At present, the commonly used method in engineering is to drill holes in the column walls on both sides of the floor adjacent hole to install expansion screws, install the safety rope on the expansion screws, and then the workers will tie the safety belt to the reinforced safety rope during construction. This method requires drilling holes and installing expansion screws at each adjacent hole, and the safety rope needs to be fixed to the expansion screws. It requires a special person to install and remove. The operation process is cumbersome and time-consuming. The installation of expansion screws destroys the finished components and cannot be reused, which increases the cost sharply. Summary of the invention

The reference foot 4 and the movable foot 5 are provided with mutually symmetrical clamping devices 41 at the bottom. The locking component comprises an upper sleeve 1 and a lower sleeve 2. The upper sleeve 1 and the lower sleeve 2 are arranged horizontally and parallel to each other and are located between the reference foot 4 and the movable foot 5. The right end of the upper sleeve 1 is fixed to the top of the movable foot 5, and the other end is at a certain distance from the top of the reference foot 4. The right end of the lower sleeve 2 is fixed to the middle of the movable foot 5, and the other end is at a certain distance from the reference foot 4. The upper sleeve 1 comprises a first outer sleeve 11 and a first inner sleeve 12 which are sleeved together. The two can move relative to each other. For convenience, the locking component may not be provided. If for safety, a locking component may also be provided separately. The first inner sleeve 12 is longer than the first outer sleeve 11, and the left end is fixedly connected to the top of the reference foot 4. The lower casing 2 includes a second outer casing 21 and a screw rod 22 which are threadedly connected and fixed by a screw nut 23. The screw rod 22 is longer than the second outer casing 21. The screw nut 23 locks the screw rod 22 and the second outer casing 21 by rotating the screw rod 22. The left end of the screw rod 22 is fixedly connected to the middle of the reference foot.

[0019] A rotatable seat belt extender 3 is also fixed between the upper sleeve 1 and the lower sleeve 2. The seat belt extender 3 is columnar and includes a rotating outer tube 31 and a second inner tube 32. The two ends of the second inner tube 32 are respectively fixedly connected to the upper sleeve 1 and the lower sleeve 2. The rotating outer tube 31 is rotatably sleeved on the outer layer of the second inner tube 32, and a steel wire rope 34 is installed on the rotating outer tube 31. One end of the steel wire rope 34 is fixed in the seat belt extender 3, and the other end is fixed with a second seat belt tie 35 for connecting the seat belt. A rotating handle 33 is fixed on the outer rotating outer tube 31 of the seat belt extender 3, which is used to control the rotation of the rotating outer tube 31, so that the seat belt extender 3 forms a rotatable structure in which the rotating outer tube 31 is rotatable and the second inner tube 32 is fixed. The length of the steel wire rope 34 is preferably 2 meters.
